In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of special nodes, and if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all the nodes in the system can also achieve consensus on the transaction.

An execution subject of the embodiment of the present application is a computer device, where the computer device is a terminal or a server, and the computer device is an information management server capable of updating a location parameter, as shown in fig. 1, to describe an implementation environment of the embodiment of the present application, where the implementation environment includes: the mobile terminal comprises at least three terminal devices 101 and an information management server 102, wherein the at least three terminal devices belong to the same geographical area, the at least three terminal devices 101 are used for reporting position parameters to the information management server 102, and the information management server 102 is used for updating wrong position parameters in the position parameters reported by the at least three terminal devices 101 based on the received position parameters.

The information management server 102 is an independent physical server, or a server cluster or distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, CDN (Content Delivery Network), big data and artificial intelligence platform, and the like.

The at least three terminal devices 101 are respectively connected with the information management server 102 directly or indirectly through wired or wireless communication, which is not limited in the embodiment of the present application.

In a possible implementation manner, the information management server 102 manages terminal devices in a plurality of geographic areas, as shown in fig. 2, the information management server 102 is further connected to at least three terminal devices 103 and at least three terminal devices 104, where areas to which the at least three terminal devices 103 belong, areas to which the at least three terminal devices 104 belong, and areas to which the at least three terminal devices 101 belong are different, and in fig. 2, it is shown that the at least three terminal devices 101 belong to an area a, the at least three terminal devices 103 belong to an area B, and the at least three terminal devices 104 belong to an area C. The information management server 102 updates the location parameters of the terminal devices in the same geographic area, such as correcting incorrect location parameters, based on the location parameters of at least three terminal devices in the same geographic area.

In a possible implementation manner, the information management server 102 is a blockchain link point in a blockchain system, such as the structural diagram of the blockchain system shown in fig. 3, where the blockchain system includes a plurality of blockchain nodes, the plurality of blockchain nodes are information management servers, and any one blockchain link point in the blockchain system may perform one or more steps of the location parameter updating method provided by the embodiment of the present application. Wherein the block link point is connected to a plurality of terminal devices. A point-To-point (P2P, Peer To Peer) network formed between blockchain nodes, and the P2P Protocol is an application layer Protocol operating on a Transmission Control Protocol (TCP). In the blockchain system, any computing device such as a server, a user terminal, etc. can be added to form a blockchain node.

Referring to the functions of each blockchain node in the blockchain system shown in fig. 3, the functions involved include routing and application, wherein the routing is used for supporting communication between blockchain nodes, and the application is used for deployment in the blockchain system, and a specific service is realized according to actual service requirements:

The block may include information such as a time stamp at the time of block generation.

The location parameter updating method provided by the embodiment of the application can be applied to any scene for updating location parameters. For example, in a scenario of online shopping and online payment, a plurality of terminal devices 501 for performing face-brushing payment or code-scanning payment are deployed in different stores by dividing The stores into regions, and as shown in fig. 5, The terminal device 501 is a face terminal device of The Internet of Things (IOT).

Each terminal device 501 reports the position parameters to the information management server, and the information management server processes the position parameters reported by at least three terminal devices 501 belonging to the same store by using the method provided by the embodiment of the application, so as to determine the accurate reference position parameters and the wrong position parameters, and replace the wrong position parameters with the reference position parameters, thereby realizing the automatic correction of the wrong position parameters.

Fig. 6 is a flowchart of a location parameter updating method according to an embodiment of the present application. An execution subject of the embodiment of the present application is an information management server, and referring to fig. 6, the method includes:

601. the information management server determines a difference between the position parameters of each two devices as a distance between each two devices according to the position parameters of at least three devices belonging to the target area.

In the embodiment of the application, a plurality of devices for providing services for users, such as terminal devices for code scanning payment or face brushing payment, are deployed in different areas, and the devices can process service requests of the users. Alternatively, the area is divided according to the requirement, for example, the area is divided by stores in the scene of online shopping, and one store is one area. Alternatively, the regions are divided according to geographical location, e.g., one cell is a region, one street is a region, etc.

The information management server is used for managing the position parameters of the devices, and ensuring the safety of the service request of the user according to the position parameters of the devices, namely performing risk control on the service request. For example, if the information management server determines that the face recognition is performed on the user a by the device in beijing in the previous minute and the face recognition is also performed on the user a by the device in shenzhen in the next minute based on the location parameter of the device, it indicates that the service request of the user a is at risk, and the information management server performs interception processing on the service request of the user a.

However, the location parameter stored in the information management server may be an erroneous location parameter, and thus the location parameter needs to be updated to correct the erroneous location parameter. In the embodiment of the application, the position parameters of the devices in the area are updated by taking the position parameters of the devices in the area as a reference, taking into account that the actual position parameters of the devices in the area have small differences.

Taking the example of updating the location parameters of the devices belonging to the target area, the information management server determines the difference between the location parameters of each two of the at least three devices according to the location parameters of the at least three devices belonging to the target area, and determines the distance between each two devices according to the difference between the parameters of each two devices.

602. The information management server determines the position parameter of one of the devices corresponding to the minimum distance among the plurality of distances as a reference position parameter.

Since the at least three devices all belong to the target area, and the actual distance between each two devices in the at least three devices is small, if the location parameter reported by the device is correct, the distance between each two devices determined according to the location parameter should be small, so the information management server selects the minimum distance from the determined multiple distances, and can determine the location parameter of one of the two devices as the reference location parameter, where the reference location parameter is used to correct the wrong location parameter, if the location parameter corresponding to the minimum distance is an accurate location parameter.

603. And if at least two distances corresponding to any one of the at least three devices are greater than a first distance threshold, the information management server replaces the position parameter of any one device with the reference position parameter.

If the distance between any two devices is greater than a certain threshold, the location parameter of one of the two devices may be considered erroneous. In the embodiment of the present application, a first distance threshold is used as a reference, and if a certain distance is greater than the first distance threshold, it is determined that a location parameter of at least one device exists in two devices corresponding to the distance, which is wrong. Optionally, the first distance threshold is a distance between two points that are farthest apart in the target region. Optionally, the first distance threshold is set by the information management server itself, or determined by the information management server according to a setting operation of a maintenance worker, which is not limited in this embodiment of the application.

Since each of the at least three devices corresponds to at least two distances, assuming that the location parameter of a certain device is a wrong location parameter, the at least two distances corresponding to the certain device are both greater than the first distance threshold. Therefore, if at least two distances corresponding to any one of the at least three devices are greater than the first distance threshold, it is indicated that the location parameter of the any one device is erroneous, and the information management server replaces the location parameter of the any one device with the reference location parameter, thereby correcting the erroneous location parameter.

In the method provided by the embodiment of the present application, since at least three devices belong to the target area, the true distance between every two devices in the at least three devices is small, and if the location parameter reported by the device is correct, the distance between any two devices determined according to the location parameter of the device should be small. On the contrary, if at least two distances among the distances between any one device and other devices are greater than the first distance threshold, the position parameters of the any one device are not accurate. Therefore, the position parameter of one of the devices corresponding to the minimum distance is used as a reference position parameter to replace the position parameter of any one of the devices, and the wrong position parameter reported by the device is automatically corrected by referring to the position parameters of other devices in the same area, so that the accuracy of device positioning is guaranteed.

Fig. 7 is a flowchart of a location parameter updating method according to an embodiment of the present application. An execution subject of the embodiment of the present application is an information management server, and referring to fig. 7, the method includes:

701. and the information management server receives POI information reported by the multiple devices.

In the embodiment of the present application, a plurality of devices for providing services for a user are deployed in different areas, and the plurality of devices respectively report Point of Interest (POI) information to an information management server. The POI information of the device includes information related to the device, such as a device identifier, an area identifier of an area to which the device belongs, and a location parameter of the device.

In a possible implementation manner, multiple devices in the same area can be connected to each other, in this embodiment of the application, the connection condition of any two devices is that a distance between any two devices is smaller than a second distance threshold, for example, a bluetooth connection is established between any two devices, and a maximum distance of the bluetooth connection is the second distance threshold. Or, a wired connection is established between any two devices, and the maximum distance of the wired connection is the second distance threshold.

In one possible implementation manner, the POI information of the device includes a first device identifier, a second device identifier, a location parameter of the device, and an area identifier. The first device identifier included in the POI information is used to indicate a device that reports the POI information, for example, the first device identifier is a Serial Number of the device, a Serial Number (SN) of the device, or the like. The area identifier included in the POI information is used to indicate an area to which the device reporting the POI information belongs, for example, if an area is divided into stores, the area identifier is a store identifier, such as a store name. The second device identifier included in the POI information is used to indicate other devices connected to the device reporting the POI information. The location parameters included in the POI information are used to indicate the location where the device is located, and for example, the location parameters are longitude parameters and latitude parameters. The device may perform Positioning in different manners to obtain the location parameter, for example, Positioning via GPS (Global Positioning System), WIFI (wireless internet access), or base station.

For example, the data format of the POI information reported by the device is as follows:

{poi:{latitude,longtitude},b_sn:{sn1,sn3},storeid:store1,sn:sn2}；

the POI indicates POI information, latiude indicates a latitude parameter, longtitude indicates a longitude parameter, { latiude, longtitude } indicates a location of the device, b _ SN indicates an SN list of other devices connected to the device, the SN list includes SN1 and SN3, storeid indicates a store identifier of a store to which the device belongs, SN indicates a device identifier of a device reporting the POI information, and the device identifier is SN 2.

And the information management server receives the POI information reported by the multiple devices and manages the POI information of the devices. Wherein the information management server provides location parameter update services based on the POI information of the device, and in addition, the computer device can provide other services, such as risk control services, location parameter query services, and the like, based on the POI information of the device.

In a possible implementation manner, a POI database is arranged in the information management server, and the information management server stores POI information of any device into the POI database when receiving the POI information reported by any device.

702. The information management server establishes a first association relationship between the area identifier and the first device identifier contained in each POI message.

In order to update the location parameters of the devices belonging to the same area based on the location parameters of the devices in the same area, it is necessary to determine the relationship between the areas and the devices, that is, to determine which area each of the multiple devices reporting the POI information belongs to. Therefore, the information management server analyzes the multiple pieces of POI information to obtain the area identifier and the first device identifier included in each piece of POI information.

The area identifier is used for indicating an area to which the device reporting the POI information belongs, and the first device identifier is used for indicating the device reporting the POI information, so that the information management server establishes a first association relationship between the area identifier included in each POI information and the first device identifier, and the first association relationship comprises an association relationship between the area identifier corresponding to any area and the first device identifier corresponding to any device belonging to any area, and can indicate which devices exist in any area.

703. And the information management server establishes a second association relationship between the area identifier and the second equipment identifier contained in each POI message.

The information management server analyzes the multiple pieces of POI information, and obtains a second device identifier included in each piece of POI information, where the second device identifier is used to indicate another device to which the device reporting the POI information is connected, and because a connection condition of any two devices is that a distance between any two devices is smaller than a second distance threshold, a distance between a first device corresponding to the first device identifier and a second device corresponding to the second device identifier is smaller than the second distance threshold, that is, the second device is closer to an area to which the first device belongs, within an acceptable error, the location parameters between the devices connected to each other can be corrected mutually, that is, the location parameters of the second device can also be used to update the location parameters of the devices in the area to which the first device belongs.

The information management server establishes a second association relationship between the area identifier included in each piece of POI information and the second device identifier, where the second association relationship includes an association relationship between the area identifier corresponding to any area and the second device identifier corresponding to another device connected to any device belonging to any area, and can indicate which devices exist in any area or in the vicinity of any area.

It should be noted that, in the embodiment of the present application, only the first association relationship between the first device identifier and the area identifier is respectively established, and the second association relationship between the second device identifier and the area identifier is established as an example for explanation. In another embodiment, the information management server analyzes the POI information to obtain a first device identifier, a second device identifier and an area identifier included in the POI information, and the information management server directly establishes a first association relationship between the first device identifier and the area identifier because the area identifier represents an area to which the first device belongs. Because the second device is connected with the first device, the second device may or may not belong to the area to which the first device belongs, the information management server queries the area to which the second device belongs based on the multiple pieces of POI information, if the area to which the second device belongs is the same as the area to which the first device belongs, the information management server establishes a first association relationship between the second device identifier and the area identifier, and if the area to which the second device belongs is not the same as the area to which the first device belongs, the information management server establishes a second association relationship between the second device identifier and the area identifier.

704. And the information management server inquires a first equipment identifier corresponding to the target area identifier according to the established first incidence relation.

In the embodiment of the present application, the location parameter of the device belonging to the target area is updated as an example, so after the information management server establishes the association relationship between the area identifier and the device identifier, if the location parameter of the device belonging to the target area is to be updated, which devices are included in the target area is queried. The information management server inquires a plurality of first equipment identifications corresponding to the target area identification according to the established first incidence relation, wherein the target area identification is used for indicating the target area.

705. And the information management server inquires the position parameter corresponding to the first equipment identifier.

After the information management server queries the first device identifier, it queries a location parameter corresponding to the first device identifier, that is, a location parameter reported by the first device indicated by the first device identifier.

When the device performs positioning, there may be a situation that positioning fails and the device does not acquire the location parameter, so the device may not report the location parameter, or the reported location parameter is null. Therefore, when the information management server queries the location parameters corresponding to the plurality of first device identifiers, the location parameters corresponding to a certain first device identifier may not be queried. For example, the information management server queries 7 first device identifiers, and when querying the location parameters corresponding to the 7 first device identifiers, only the location parameters corresponding to 5 of the 7 first device identifiers are queried, and the location parameters corresponding to the remaining 2 first device identifiers are not queried.

In one possible implementation manner, the information management server queries the location parameter corresponding to the first device identifier from the received multiple pieces of POI information. That is, the POI information reported by the first device indicated by the first device identifier is queried from the multiple pieces of POI information, and the location parameter included in the POI information is obtained.

706. And the information management server inquires a second equipment identifier corresponding to the target area identifier according to the established second incidence relation.

In the embodiment of the present application, the location parameter of the device belonging to the target area is updated as an example, so after the information management server establishes the association relationship between the area identifier and the device identifier, it is queried which devices are connected to all devices included in the target area, in addition to which devices are included in the target area. And the information management server inquires a plurality of second equipment identifications corresponding to the target area identification according to the established second incidence relation. Since the second devices indicated by the plurality of second device identifications are closer to the target area, the plurality of second devices can be approximately considered to belong to the target area.

707. And the information management server inquires the position parameter corresponding to the second equipment identifier.

After the information management server queries the second device identifier, it queries the location parameter corresponding to the second device identifier, that is, the location parameter reported by the device indicated by the second device identifier.

In one possible implementation manner, the information management server queries the location parameter corresponding to the second device identifier from the received multiple pieces of POI information. That is, the POI information reported by the second device indicated by the second device identifier is queried from the multiple POI information, and the location parameter included in the POI information is obtained.

It should be noted that, in the embodiment of the present application, only the first association relationship and the second association relationship are respectively established, and the first device identifier is queried in the first association relationship, and the second device identifier is queried in the second association relationship. In another embodiment, the information management server only establishes the first association relationship without establishing the second association relationship, that is, the information management server only performs the

steps

702 and 704 and 707 without performing the

steps

703 and 706 and 707.

708. The information management server determines a difference between the position parameters of each two devices as a distance between each two devices according to the position parameters of at least three devices belonging to the target area.

The information management server determines the difference value between the position parameters of every two devices in the at least three devices according to the inquired position parameters of the at least three devices belonging to the target area, and determines the distance between every two devices according to the difference value between the parameters of every two devices.

Optionally, the information management server obtains, by query, a location parameter corresponding to the first device identifier and a location parameter corresponding to the second device identifier, where the first device indicated by the first device identifier belongs to the target area, and a distance between the second device indicated by the second device identifier and a device in the target area is smaller than a second distance threshold, which may approximately be considered that the second device belongs to the target area. That is, the at least three devices include a device belonging to the target area and a device establishing a connection with a device in the target area.

Optionally, the information management server only queries the location parameter corresponding to the first device identifier, and does not query the location parameter corresponding to the second device identifier. That is, only the devices belonging to the target area are included in the at least three devices, and the devices establishing connection with the devices in the target area are not included.

709. The information management server determines the position parameter of one of the devices corresponding to the minimum distance among the plurality of distances as a reference position parameter.

Since the at least three devices all belong to the target area, and the actual distance between each two devices in the at least three devices is small, if the location parameter reported by the device is correct, the distance between each two devices determined according to the location parameter should be small, so the information management server selects the minimum distance from the determined multiple distances, and can determine the location parameter of one of the two devices as the reference location parameter, where the reference location parameter is used to correct the wrong location parameter, if the location parameter corresponding to the minimum distance is an accurate location parameter. The information management server may randomly select one of the two devices, and determine a location parameter of the selected device as a reference location parameter.

In one possible implementation manner, the information management server determines a minimum distance smaller than a third distance threshold value in the plurality of distances, and determines a location parameter of one of the devices corresponding to the minimum distance as a reference location parameter.

The information management server determines a distance smaller than a third distance threshold value in the plurality of distances, and if the information management server determines only one distance smaller than the third distance threshold value, determines the position parameter of one device corresponding to the distance as a reference position parameter. And if the information management server determines a plurality of distances smaller than the third distance threshold, selecting a minimum distance from the determined distances, and determining the position parameter of one device corresponding to the minimum distance as the reference position parameter.

710. And if at least two distances corresponding to any one of the at least three devices are greater than a first distance threshold, the information management server replaces the position parameter of any one device with the reference position parameter.

Different devices have different positioning modes, such as GPS positioning, WIFI positioning, or base station positioning, due to differences in hardware configuration or differences in device connection networks. The different positioning methods cause differences in the obtained location parameters, and there may be situations where the location parameters are missing or inaccurate, so it is necessary to determine whether the location parameters reported by the device are wrong location parameters.

Since the at least three devices all belong to the target area, the actual distance between every two devices of the at least three devices will be small, and therefore, if the location parameter reported by the device is correct, the distance between every two devices determined according to the location parameter should be small. Since each of the at least three devices corresponds to at least two distances, assuming that the location parameter of a certain device is a wrong location parameter, the at least two distances corresponding to the certain device are both greater than the first distance threshold. Therefore, if at least two distances corresponding to any one of the at least three devices are greater than the first distance threshold, it is indicated that the location parameter of the any one device is erroneous, and the information management server replaces the location parameter of the any one device with the reference location parameter, thereby correcting the erroneous location parameter. In the embodiment of the application, the position parameters of the same area are shared, so that a scheme for correcting the abnormal position parameters of the equipment based on end-to-end data sharing is realized.

Optionally, the first distance threshold is a distance between two points that are farthest apart in the target region. Optionally, the first distance threshold is set by the information management server itself, or determined by the information management server according to a setting operation of a maintenance worker, which is not limited in this embodiment of the application.

In one possible implementation, the location parameters include a longitude parameter and a latitude parameter.

Then, in the above-described step 708, the information management server determines, as a longitude distance between each two devices, a difference between the longitude parameters of each two devices based on the longitude parameters of at least three devices, and determines, as a latitude distance between each two devices, a difference between the latitude parameters of each two devices based on the latitude parameters of at least three devices.

In step 709, the information management server determines a longitude parameter of one of the devices corresponding to a minimum longitude distance of the plurality of longitude distances as a reference longitude parameter; the information management server determines a latitude parameter of one of the devices corresponding to a minimum latitude distance among the plurality of latitude distances as a reference latitude parameter.

In step 710, if at least two longitude distances corresponding to any one of the at least three devices are greater than the longitude distance threshold, the information management server replaces the longitude parameter of the any one device with the reference longitude parameter. If at least two latitude distances corresponding to any one of the at least three devices are greater than the latitude distance threshold, the information management server replaces the latitude parameter of the any one device with the reference latitude parameter.

711. And if the position parameter corresponding to any first equipment identifier is not inquired, the information management server determines the reference position parameter as the position parameter corresponding to any first equipment identifier.

In step 705 above, when the information management server queries the location parameter corresponding to the first device identifier, there may be a case that the location parameter corresponding to a certain first device identifier is not queried, that is, the location parameter not reported by the first device corresponding to the first device identifier or the reported location parameter is null, and the location parameter of the first device identifier needs to be automatically supplemented. Therefore, if the location parameter corresponding to any first device identifier is not queried, the information management server determines the reference location parameter as the location parameter corresponding to any first device identifier after determining the reference location parameter. Therefore, the problem that the position parameters of partial devices in the same area are lost is effectively solved by sharing the position parameters of the devices in the same area, so that the condition that the service is unavailable due to the lack of the position parameters is avoided, and the service availability is improved.

It should be noted that, the embodiment of the present application only describes a process of determining the reference location parameter as the location parameter corresponding to the first device identifier. In another embodiment, in step 707, when the information management server queries the location parameter corresponding to the second device identifier, there may be a case where the location parameter corresponding to a certain second device identifier is not queried, and if the location parameter corresponding to any second device identifier is not queried, the information management server determines the reference location parameter as the location parameter corresponding to the any second device identifier.

It should be noted that the embodiments of the present application only illustrate how to update the location parameters when the location parameters of at least three devices are queried. In another embodiment, if only two first device identifiers corresponding to the target area identifier are queried, and the location parameter corresponding to one of the first device identifiers is queried, but the location parameter corresponding to the other first device identifier is not queried, the information management server cannot determine which location parameter is correct and which location is wrong according to the distance between the devices, and therefore the information management server directly determines the queried location parameter as the location parameter corresponding to the other first device identifier.

For example, when the information management server queries that the target area identifier corresponds to the device identifier 1 and the device identifier 2, and queries the location parameters corresponding to the device identifier 1 and the device identifier 2, the information management server only queries the location parameter corresponding to the device identifier 1, and does not query the location parameter corresponding to the device identifier 2, and then determines the location parameter corresponding to the device identifier 2 as the location parameter corresponding to the device identifier 2.

It should be noted that, in the embodiments of the present application, only the information management server stores the reference location parameter as an example. In another embodiment, the information management server is a blockchain link point in a blockchain system, after the reference location parameter is acquired in step 709, the information management server stores the reference location parameter in the blockchain, and if at least two distances corresponding to any one of the at least three devices are greater than a first distance threshold, queries the reference location parameter from the blockchain, and replaces the location parameter of the any one device with the reference location parameter.

After the information management server determines the reference position parameter, a block including the reference position parameter is generated, the block is broadcasted to block chain nodes in the block chain system, the block is identified by a plurality of block chain nodes in the block chain system, and when the block passes the identification, the block is added to a block chain of the block chain system.

Optionally, the information management server stores the received POI information, the established first association relationship, the established second association relationship, and the like in the blockchain, in addition to storing the reference position parameter in the blockchain.

It should be noted that, in the embodiment of the present application, only the execution subject is taken as an example of the information management server, and in another embodiment, the execution subject may also be a terminal having an information management function, and the terminal executes the above-mentioned

step

701 and 711 to implement the location parameter updating method.

The store 802 is identified as store 1. The device identification of the 4G device 8021 is SN1, and the location parameters are determined according to GPS positioning; the device identifier of the WIFI device 8022 is SN2, and the location parameters are determined according to WIFI positioning; the device identification of the 4G device 8023 is SN3, determining location parameters from the base station location. Fig. 8 illustrates an example in which the location parameter is a longitude parameter and a latitude parameter, where LO denotes the longitude parameter and LA denotes the latitude parameter. The 4G device 8021, the WIFI device 8022, and the 4G device 8023 report POI information to the information management server 801, respectively, where the POI information includes a location parameter.

(2) When the position parameters in the POI information have null values and the number of the devices in the store is 2, the position parameters which are not null values are determined as reference position parameters, and the position parameters of the abnormal devices are replaced by the reference position parameters.

4. The face recognition module 8014 is configured to provide a verification service for face recognition. In the embodiment of the present application, when a user performs face recognition on a device in a store, the terminal may call a face recognition module of the information management server 801 to perform identity authentication. And, the risk control module 8015 is invoked to perform risk judgment in the authentication process, thereby intercepting a high-risk service request.

5. The risk control module 8015 is configured to manage a risk policy of a service, where a location parameter in a POI in the risk policy is a core factor, and is configured to reflect a location where a user requests a service based on a location parameter of a device, for example, if the user a uses a face recognition service on a device in beijing in the previous minute and uses a face recognition service on a device in shenzhen in the next minute, the service request of the user a has a certain risk and needs to be intercepted. In the embodiment of the present application, when a service request of an SN device with an abnormal location parameter is found, the location decision module 8013 is called, the location parameter of the SN device is updated by using a reference location parameter, and if the reference location parameter is not queried, the service request is directly intercepted.

As shown in fig. 8, the information management server 801 stores therein the association relationship between the identification store1 of the store 802 and the device identifications SN1, SN2, and SN3 corresponding to the devices in the store 802. The position parameters corresponding to the SN1 are LA1 and LO1, the position parameters corresponding to the SN2 are LA2 and LO2, and the position parameters corresponding to the SN3 are LA3 and LO 3. Wherein, according to the difference values among LO1, LO2 and LO3, determining that LO1 and LO2 are accurate longitude parameters and LO3 is wrong longitude parameters, replacing LO3 with LO1 or LO2, thereby completing the updating of the position parameters.

And because the connection condition of any two devices is that the distance between any two devices is smaller than the second distance threshold, the position between the devices is further confirmed according to the connection between the devices, so that the second association relationship is established, the position parameters are mutually corrected through the devices connected with each other within an acceptable error, and the accuracy of the device positioning is further ensured.

In addition, the problem that the position parameters of partial devices in the same area are lost is effectively solved by sharing the position parameters of the devices in the same area, so that the condition that the service is unavailable due to the lack of the position parameters is avoided, and the service availability is improved.
