In order to facilitate understanding of the technical solutions provided by the embodiments of the present application by those skilled in the art, the following briefly describes related technologies:

in an application scenario dedicated for a 5G private network, the 5G private network device may include a core network (control plane 5GC-CP, user plane function 5 GC-UPF) and a 5G base station RAN. After the control plane 5GC-CP is deployed on the public cloud, because the UPF is a full sinking scheme in the application scenario of the private network, most of the scenario data in the private network does not need to go out of the park, and part of the data can go out of the park through the N6 interface, so that for the 5G base station (Radio Access Network, abbreviated as RAN) and the user plane function (User Plane Function, abbreviated as UPF) equipment, the possibility of combining the RAN and the UPF is provided.

Referring to fig. 1, the technical solution provided at present is to integrate the complete RAN and UPF directly into the field device without any modification to the 5GRAN and UPF, and then the core network control plane 5GC-CP may be deployed on the cloud, where the field device is suitable for accessing the local application and the public network application, but resources between the RAN and UPF may be wasted because the private network data mostly does not go out of the park. In particular, referring to fig. 2-3, when integrating RAN and UPF into field devices, a specific network architecture may be: the core network 5GC-CP and the user plane function-control plane UPF-CP are deployed on public cloud, the user plane function-data plane UPF-UP and the base station RAN are deployed on private network site, wherein the user plane RAN-UP of the base station can be connected with UPF through N3 interface communication. The RAN-UP comprises a service data adaptation (Service Data Adaption Protocol, SDAP) module, a packet data convergence (PacketData Convergence Protocol, PDCP) module, a radio link Layer control (Radio Link Control, RLC) module, a medium access control (Medium Access Control, MAC) module and a Physical Layer (PHY) module, wherein the PDCP module and the SDAP module are in communication connection with a GPRS tunneling protocol GTP-U module, and are used for transmitting data required to be transmitted between the 5G RAN and the UPF through a GTP protocol and a data packet encapsulation operation, and then the data subjected to the GTP encapsulation operation can be transmitted to the UPF through an N3 interface. After the UPF receives the data, the data is unpackaged by using a GTP-U module included in the UPF, and the data after the unpackaged operation is forwarded by using an IP module.

However, the above-described data transmission process has the following problems: (1) Because the performance and the reliability of the public network have larger uncertainty, in the process of data transmission between the 5G RAN and the UPF, the data transmission operation can be ensured through an N3 interface and a GTP related encryption and decryption mechanism; the performance and reliability of the private network are far higher than those of the public network, and especially when the 5G RAN and UPF are deployed in unified equipment on the private network site at the same time, the mechanism of encapsulation and connection encapsulation required by data to be transmitted has no practical effect, so that the waste of resources is caused; (2) Because the GTP modules are deployed in the 5G RAN and the UPF to realize the data encapsulation or decapsulation operation, GTP processing resources occupy a larger proportion in the 5G RAN and the UPF, so that the processing resource requirements on the whole field-embodying equipment are higher, the cost of data transmission is increased, and the processing resource of the field equipment is wasted.

In order to improve the utilization rate of resources and the integration level of devices and reduce the cost of the devices, the embodiment provides a private network device, a data processing method, a vehicle control method and a device, and specifically, referring to fig. 4, the private network device may be deployed on a private network, and the private network device may be in communication connection with a terminal device and a core network control plane to implement data processing operation. The core network control plane may include a mobility management function (Access and Mobility Function, abbreviated as AMF) network element, a session management function (Session Management Function, abbreviated as SMF) network element, a user plane data forwarding (User Plane Function, abbreviated as UPF) control plane, and the like, and the private network device may also be communicatively connected to the UPF control plane through an included UPF data plane proxy module.

In addition, for the core network control plane, the core network control plane may be deployed at the cloud, it may be understood that the cloud may be deployed with one or more core network control planes, one core network control plane may generate or establish one or more core network control plane instances, and the core network control plane instances may provide corresponding public cloud services for single tenants or multiple tenants. In some examples, the core network control plane may configure a plurality of core network control plane instances, and more flexible and reliable cloud services may be provided by the plurality of core network control plane instances.

The terminal device may be any computing device with a certain data transmission capability, and in specific implementation, the terminal device may be a mobile phone, a personal computer PC, a tablet computer, a data acquisition device, a virtual reality head display device, a vision quality inspection device, an AGV vehicle, and the like. Furthermore, the basic structure of the terminal device may include: at least one processor. The number of processors depends on the configuration and type of terminal device. The terminal device may also comprise a Memory, which may be volatile, such as RAM, or nonvolatile, such as Read-Only Memory (ROM), flash Memory, etc., or both. The memory typically stores an Operating System (OS), one or more application programs, program data, and the like. In addition to the processing unit and the memory, the terminal device comprises some basic configuration, such as a network card chip, an IO bus, a display component, and some peripheral devices. Alternatively, some peripheral devices may include, for example, a keyboard, a mouse, a stylus, a printer, and the like. Other peripheral devices are well known in the art and are not described in detail herein.

Specifically, the private network device may include: the system comprises a wireless access module, a Packet Data Convergence Protocol (PDCP) module and a shunting processing module; the wireless access module is in communication connection with the PDCP module, the PDCP module is in communication connection with the shunt processing module, in some examples, the PDCP module may be in communication connection with the shunt processing module through an N3 interface, and the wireless access module, the PDCP module, and the shunt processing module are configured to perform the following steps:

the wireless access module is in communication connection with the terminal equipment through a wireless access technology and obtains data to be processed sent by the terminal equipment; the radio access technology (radio interface technologies, abbreviated as RIT) refers to a technology of connecting a terminal device with a network node through a wireless medium to realize information transfer between a user and the network, and is also called an air interface.

And the Packet Data Convergence Protocol (PDCP) module is in communication connection with the wireless access module and is used for generating a PDCP data packet to be processed based on the data to be processed.

And the distribution processing module is used for acquiring the PDCP data packet, determining flow table information for processing the PDCP data packet, and forwarding the PDCP data packet based on the flow table information.

Specifically, the wireless access module may be in communication connection with one or more terminal devices through a wireless access technology, when there is a data processing requirement, the wireless access module may acquire data to be processed sent by the terminal devices, then the PDCP module may acquire the data to be processed through the wireless access module, specifically, the data to be processed may be actively acquired by the PDCP module, or may also be passively acquired by the PDCP module, for example, a private network device is in communication connection with a core network and/or one or more terminal devices (may be a mobile phone, a computer, a tablet computer, a data acquisition device, etc.), the terminal devices may send the data to be transmitted to the private network device through the wireless access module, and then the PDCP module may passively acquire the data to be transmitted through the wireless access module; or when the wireless access module detects that the terminal equipment has the data to be processed, the PDCP module can actively acquire the data to be processed from the terminal equipment through the wireless access module. After the PDCP module obtains the data to be processed, a PDCP packet to be processed may be generated based on the data to be processed, and the number of generated PDCP packets may be one or more.

When the PDCP module generates a PDCP data packet to be processed, in order to enable data processing operation, the shunt processing module may acquire the PDCP data packet through the PDCP module, and it should be noted that the shunt processing module may actively or passively acquire the PDCP data packet through the PDCP module.

After the PDCP data packet is obtained by the splitting processing module, since the PDCP data packet is not subjected to the GTP protocol encapsulation operation, the PDCP data packet does not need to be subjected to the GTP decapsulation operation, but the PDCP data packet can be directly analyzed to determine flow table information for processing the PDCP data packet.

In some examples, flow table information for processing PDCP packets may be stored in a preset area, after the PDCP packets are acquired, an identity of a data radio bearer corresponding to the PDCP packets may be determined, and then the preset area may be accessed based on the identity of the data radio bearer, so that flow table information for processing PDCP packets may be determined.

In other examples, the flow table information may be obtained not only by accessing a preset area, but also when the terminal device accesses to the core network, and specifically, the private network device may be communicatively connected to at least one terminal device through a wireless access module; at this time, the split-flow processing module is specifically configured to: acquiring a first mapping relation between a Tunnel Endpoint Identifier (TEID) and an identity of a data radio bearer and a second mapping relation between the TEID and an IP address of a terminal device; and determining flow table information for identifying the mapping relationship between the IP address of the terminal equipment and the identity of the data radio bearer based on the first mapping relationship and the second mapping relationship.

Specifically, in order to enable the splitting processing module in the private network device to stably acquire the second mapping relationship, the private network device in this embodiment may further include: the data plane proxy module of the user plane function UPF (namely UPF-U plane proxy module) is used for establishing communication connection with a UPF control plane on the cloud.

In order to ensure that data transmission operation can be performed between private network equipment and a core network control plane, a data plane proxy module of a user plane function UPF can be established or generated in the private network equipment, specifically, standard definition for defining the data plane proxy module of the UPF can be firstly obtained, the data plane proxy module of the user plane function UPF is established in a base station based on the standard definition, the established data plane proxy module of the UPF (i.e. UPF-U plane proxy module) is used for being responsible for butting with a UPF-C (UPF control plane) on a cloud, no forwarding and processing operation of terminal local data are performed, and UPF network elements are divided into a UPF data plane (i.e. UPF-U plane proxy module) and a UPF control plane (i.e. UPF-C plane), so that the processing operation of cloud data is convenient to perform, and the cost for deploying the UPF is greatly reduced.

After the data plane proxy module of the user plane function UPF is established in the private network device, the second mapping relationship between the obtained TEID and the IP address of the terminal device in this embodiment may include: and in the process of accessing the terminal equipment into the core network, a second mapping relation between the TEID and the IP address of the terminal equipment is obtained through the data plane proxy module and the UPF control plane. Specifically, when the terminal equipment UE accesses to the network, the UE may send a PDU session establishment request to an AMF network element and an SMF network element in the core network, after the core network receives the PDU session establishment request, the core network may generate an N4 session establishment request based on the PDU session establishment request, and send the N4 session establishment request to the UPF control plane, where the UPF control plane may generate a second mapping relationship between the UE IP and the TEID, and then the private network equipment may obtain the mapping relationship between the UE IP and the TEID through the UPF control plane. In some examples, after the private network device acquires the mapping relationship between the UE IP and the TEID, feedback information for identifying the acquired mapping relationship between the UE IP and the TEID may be sent to the UPF control plane, which may send the acquired feedback information to the core network.

In addition, when the terminal device accesses to the core network, the private network device may acquire a first mapping relationship between the TEID and an identity (abbreviated as DRB ID) of the data radio bearer. After the core network obtains the feedback information, a PDU session resource setting request can be sent to the private network device to generate a first mapping relation, and after the private network device obtains the PDU session resource setting request, TEID searching and route entry adding can be performed, so that flow table information for identifying the mapping relation between the IP address of the terminal device and the identity of the data radio bearer can be obtained. Specifically, after the private network device obtains the first mapping relationship and the second mapping relationship, the first mapping relationship and the second mapping relationship may be directly analyzed and processed, so that flow table information for identifying the mapping relationship between the UE IP and the DRB ID may be determined.

After the flow table information and the PDCP data packet are obtained by the flow table processing module, forwarding operation can be performed on the PDCP data packet based on the flow table information, in some examples, since the flow table information is used to identify a mapping relationship between the UE IP and the DRB ID, the PDCP data packet corresponds to the DRB ID, so that the UE IP corresponding to the PDCP data packet can be obtained through the flow table information, and then forwarding operation can be performed on the PDCP data packet through the IP module, thereby effectively implementing forwarding operation of data without performing any GTP packet or packet unpacking operation on the data.

In still other examples, to enable the private network device to have similar functions and capabilities as the base station, the private network device may further include, in addition to the PDCP module and the shunt processing module:

a physical layer PHY module for providing a transport channel to the medium access control MAC module;

the MAC module is in communication connection with the PHY module and the Radio Link Control (RLC) module and is used for providing logic signals for the RLC module;

the RLC module is in communication connection with the PDCP module and is used for providing an RLC channel for the PDCP module;

the PDCP module is in communication connection with the service data adaptation SDAP module and is used for providing a radio bearer for the SDAP module;

And the SDAP module is used for providing service quality information for the core network.

In addition, for the private network device, in order to stably implement the data forwarding operation, the private network device may include not only a PDCP module and a shunt processing module, but also an IP module and an ethernet module that are communicatively connected to the shunt processing module, where the IP module is used to implement the data forwarding operation, and the ethernet module is used to debug and debug a transmission signal on the ethernet.

According to the private network equipment provided by the embodiment, the data to be processed sent by the terminal equipment is obtained through the wireless access module, the data to be processed is analyzed and processed through the shunt processing module, the PDCP data packet is generated, the flow table information for processing the PDCP data packet is determined, then the PDCP data packet is forwarded based on the flow table information, the protocol stack technology (or the user mode technology) is effectively utilized to realize the private network equipment, and when the private network equipment is utilized to carry out data processing operation, any GTP processing operation is not needed, so that the expenditure of GTP processing resources is effectively reduced, the integration level of the private network equipment is improved, the cost of data forwarding is reduced, the applicability of the private network equipment is effectively expanded, and the practicability of the private network equipment is ensured.

On the basis of the above embodiment, with continued reference to fig. 4, the splitting processing module in this embodiment is capable of performing processing operation on not only uplink data, but also downlink data, and specifically, the splitting processing module in this embodiment is further configured to: acquiring data to be transmitted; determining an identity of a data radio bearer corresponding to data to be transmitted; and sending the data to be transmitted to the PDCP module for processing based on the identification of the data radio bearer.

The data to be transmitted may be downlink data to be sent to the private network device, where the data to be transmitted may be sent to the private network device through a core network (for example: a campus network), and the obtained data to be transmitted may be used to be sent to a terminal device communicatively connected to the private network device, where the terminal device may include at least one of the following: for the data to be transmitted, the data content or the form of the obtained data to be transmitted may be different in different application scenarios, for example: in an application scenario for controlling a virtual reality terminal, a mobile phone, a tablet personal computer, a personal computer and an automatic guided transport AGV, the obtained data to be transmitted can be control data for controlling the terminal equipment; or, when playing the display content of the virtual reality terminal, the obtained data to be transmitted may be data for display or playing.

In order to perform stable forwarding operation on the data to be transmitted, after the data to be transmitted is acquired, analysis processing can be performed on the data to be transmitted, so that the identity of the data radio bearer corresponding to the data to be transmitted can be determined. In some examples, the identity of the data radio bearer may be obtained by the identity of the terminal device, where the offloading processing module is specifically configured to: acquiring an identity of a terminal device corresponding to data to be transmitted; based on the identity of the terminal device, the identity of the data radio bearer corresponding to the data to be transmitted is determined.

Specifically, after the splitting processing module obtains the data to be transmitted, the data to be transmitted may be directly processed, so that the identity of the terminal device corresponding to the data to be transmitted may be obtained. In other examples, the identity of the terminal device may have a mapping relationship with the data to be transmitted, and at this time, the identity of the terminal device corresponding to the data to be transmitted may be obtained through the mapping relationship.

Because a specific data radio bearer corresponds to a terminal device, that is, an identity of a terminal device may correspond to an identity of a data radio bearer, after the identity of the terminal device is obtained, the identity of the terminal device may be analyzed, so that the identity of the data radio bearer corresponding to the data to be transmitted may be accurately determined.

It should be noted that the identity of the data radio bearer may be obtained not only by the identity of the terminal device, but also by other means in the prior art, for example: the QOS information QOS corresponding to the data to be transmitted may be acquired first, where a mapping relationship between the QOS and the identity of the data radio bearer is preconfigured, and then the identity of the data radio bearer corresponding to the data to be transmitted may be determined based on the QOS and the mapping relationship, so that accuracy and reliability of acquiring the identity of the data radio bearer are also ensured.

After the identity of the data radio bearer is obtained, the data to be transmitted can be sent to the distribution processing module for data processing based on the identity of the data radio bearer, so that the distribution processing module can perform data processing operation on the data to be transmitted, and the quality and effect of data forwarding operation are effectively ensured.

In this embodiment, the splitting processing module obtains the data to be transmitted, determines the identity of the data radio bearer corresponding to the data to be transmitted, and then sends the data to be transmitted to the PDCP module for processing based on the identity of the data radio bearer, so that it is effectively achieved that for the data to be transmitted in the downlink direction, a complete local GTP packet is not required, so that GTP resources and kernel resources required during data processing are reduced, stability and reliability of data processing operations are also ensured, and practicability of the device is further improved.

In a specific implementation, referring to fig. 5, compared with the existing network architecture, the private network device in this embodiment has and can implement related functions of the base station and the UPF, where the private network device can replace the base station and the UPF in the existing architecture to perform communication connection with the core network, and in a specific implementation, the private network device can be obtained by cutting and optimizing the related protocols related to GTP packet and packet in the protocol stack of the base station RAN and the UPF protocol stack, and can stably implement data processing operation based on the private network device. Specific:

For the data to be transmitted in the uplink direction, after the splitting processing module in the private network device acquires the PDCP data packet to be processed, the flow table information for processing the PDCP data packet can be determined, and the flow table information can directly acquire the flow table information for identifying the relation of the UE IP < - > DRB ID through the mapping relation between the TEID < - > UE IP and the mapping relation between the TEID < - > DRB ID. After the PGCP packet and the flow table information for processing the PDCP packet are acquired, the PDCP packet corresponding to the DRB ID may be directly forwarded to a channel corresponding to the UE IP according to the flow table information, so as to implement a stable processing operation on data to be transmitted in an uplink direction.

For the data to be transmitted in the downlink direction, after the shunt processing module in the private network device acquires the PDCP data packet to be processed, the shunt processing module can forward the PDCP data packet to a corresponding channel of the DRB ID for processing according to the UE ID, so that the data to be transmitted in the downlink direction is processed.

Based on the above statement, when the private network device is used for data processing operation, since the private network device has direct forwarding capability, the PDCP module in the private network device can directly perform data transmission operation with the shunt processing module without performing any GTP processing operation on the data, so that not only is the data processing resource optimized and the cost of data processing reduced, but also the integration level of the private network device is improved, and meanwhile, the problem of redundant resources caused by simple integration of the 5G RAN and the UPF can be completely eliminated.

Fig. 7 is a schematic flow chart of a vehicle control method according to an embodiment of the present application; fig. 8 is a schematic view of a scenario of a vehicle control method according to an embodiment of the present application; referring to fig. 7 to 8, the present embodiment provides a vehicle control method, in which the execution subject is a vehicle control apparatus, and it is understood that the vehicle control apparatus may be implemented as software, or a combination of software and hardware, and in particular, when the vehicle control apparatus is implemented as hardware, it may be specifically various electronic devices having a vehicle control operation. When the vehicle control apparatus is implemented as software, it may be installed in the electronic device exemplified above. In particular, the vehicle control device may be implemented as a vehicle control device deployed locally on a private network, the vehicle control device including: the system comprises a wireless access module, a Packet Data Convergence Protocol (PDCP) module and a shunting processing module which is in communication connection with the PDCP module; specifically, the vehicle control method may include:

Step S701: the wireless access module is in communication connection with the terminal equipment through a wireless access technology, and obtains data to be processed sent by the terminal equipment.

Step S705: the split flow processing module forwards the PDCP data packet to a vehicle control network based on the flow table information so as to generate control information corresponding to the vehicle to be controlled through the vehicle control network.

Specifically, in the process of driving the vehicle to be controlled (unmanned vehicle or manned vehicle), the vehicle to be controlled may be in communication connection with the vehicle control device through the base station, so as to enable the vehicle to be controlled to be accurately and effectively controlled, a PDCP module in the vehicle control device may generate a PDCP data packet corresponding to the vehicle to be controlled, and the shunt processing module may acquire the PDCP data packet corresponding to the vehicle to be controlled through the PDCP module, where the PDCP data packet may include vehicle operation data, a driving destination, a driving path, and the like, and the vehicle operation data may include a current position of the vehicle, a driving speed of the vehicle, a driving state of the vehicle, and the like. After the PDCP data packet is acquired, in order to ensure the stability and reliability of the vehicle control, flow table information for processing the PDCP data packet may be determined, and then the PDCP data packet may be forwarded to a vehicle control network based on the flow table information, specifically, after the PDCP data packet is acquired by the vehicle control network, the PDCP data packet may be analyzed and processed, so that control information corresponding to the vehicle to be controlled may be generated, so as to perform stable and effective control operation on the vehicle to be controlled based on the control information, for example, a lane on which the vehicle to be controlled is traveling may be controlled based on control information of a traveling path in the control information, that is, the vehicle to be controlled may be controlled to be switched from lane 1 to lane 2 based on the control information.

In other examples, the method in this embodiment may include the steps of obtaining the control information to be transmitted through the vehicle control network, and then sending the control information to the implementation process of the vehicle to be controlled: acquiring control information corresponding to the vehicle to be controlled; and sending the control information to the vehicle to be controlled through a data convergence protocol (PDCP) module and the PDCP module so as to control the vehicle to be controlled through the control information.

Specifically, after the PDCP data packet is acquired by the vehicle control network, the PDCP data packet may be analyzed to obtain control information corresponding to the vehicle to be controlled, and in order to enable the vehicle to be controlled to perform control operation, the vehicle control network may send the control information to the vehicle control device, so that the vehicle control device may receive and acquire the control information corresponding to the vehicle to be controlled.

After the control information is acquired, in order to accurately perform transmission operation on the control information, the control information can be sent to the PDCP module through the shunting processing module, and then the information to be controlled is sent to the vehicle to be controlled through the PDCP module, so that the vehicle to be controlled can be controlled based on the control information.

In some examples, in order to improve stability and reliability of controlling the vehicle, the vehicle to be controlled may be provided with a sensor, and the sensor may rapidly acquire the operation state data corresponding to the vehicle to be controlled, where the operation state data corresponding to the vehicle to be controlled may include at least one of the following: the method comprises the steps of current speed, running direction and environment information of a vehicle, wherein the environment information comprises distribution positions of surrounding objects, speed of the vehicle in front of the vehicle and road speed limit of a road on which the vehicle is located. In some examples, the sensors may include an image acquisition sensor, a radar sensor, and a global positioning system GPS, and in particular, the operational status data corresponding to the vehicle to be controlled is determined by the image acquisition sensor, the radar sensor, and the global positioning system GPS.

It is to be noted that, as for the vehicle control device, the vehicle control device may be provided on the vehicle, or the vehicle control device may be provided independently of the vehicle, in which case the vehicle control device may be communicatively connected to the vehicle CPU.

In addition, the vehicle control device may be adjusted according to different vehicles, that is, the algorithm modules included in the vehicle control device may be different according to different vehicle types, and at this time, the vehicle control device may implement not only the control operation of the automatic driving of the vehicle but also other operations. For example, different vehicle control devices may be involved for logistics vehicles, public service vehicles, medical service vehicles, terminal service vehicles. The algorithm modules included in the vehicle control apparatus are respectively illustrated below for these four autonomous vehicles:

Wherein, logistics vehicles refer to vehicles used in logistics scenes, such as: can be a logistics vehicle with an automatic sorting function, a logistics vehicle with a refrigerating and heat-preserving function and a logistics vehicle with a measuring function. These logistics vehicles may involve different algorithm modules.

For example, for a logistics vehicle, an automated sorting device may be provided which can automatically pick up and transport, sort and store goods after the logistics vehicle arrives at the destination. This involves an algorithm module for sorting of goods, which mainly implements logic control of goods taking out, handling, sorting and storing.

For another example, for a cold chain logistics scene, the logistics vehicle can be further provided with a refrigeration and heat preservation device, and the refrigeration and heat preservation device can realize refrigeration or heat preservation of transported fruits, vegetables, aquatic products, frozen foods and other perishable foods, so that the fruits, vegetables, aquatic products, frozen foods and other perishable foods are in a proper temperature environment, and the problem of long-distance transportation of perishable foods is solved. The algorithm module is mainly used for dynamically and adaptively calculating proper temperature of cold food or heat preservation according to information such as food (or article) properties, perishability, transportation time, current seasons, weather and the like, and automatically adjusting the cold food or heat preservation device according to the proper temperature, so that transportation personnel do not need to manually adjust the temperature when different foods or articles are transported by a vehicle, the transportation personnel are liberated from complicated temperature regulation and control, and the efficiency of cold food or heat preservation transportation is improved.

For example, in most logistics scenes, the charge is carried out according to the volume and/or weight of the packages, the number of the logistics packages is very large, and the volume and/or weight of the packages are simply measured by an express delivery person, so that the efficiency is very low, and the labor cost is high. Therefore, in some logistics vehicles, a measuring device is additionally arranged, so that the volume and/or the weight of the logistics package can be automatically measured, and the cost of the logistics package can be calculated. This involves an algorithm module for logistic parcel measurement which is primarily used to identify the type of logistic parcel, determine the way in which the logistic parcel is measured, such as whether a volumetric measurement or a weight measurement is made or a combination of volumetric and weight measurements are made simultaneously, and can perform volumetric and/or weight measurements based on the determined way of measurement, and perform cost calculations based on the measurement results.

The public service vehicle is a vehicle that provides a certain public service, for example: can be a fire truck, a deicing vehicle, a watering vehicle, a snow shovel, a garbage disposal vehicle, a traffic guidance vehicle and the like. These public service vehicles may involve different algorithm modules.

For example, for an automatically driven fire engine, the main task is to perform a reasonable fire extinguishing task for a fire scene, which involves an algorithm module for the fire extinguishing task, and the algorithm module at least needs to implement logic of fire condition identification, fire extinguishing scheme planning, automatic control of a fire extinguishing device and the like.

For another example, for deicing vehicles, the main task is to remove ice and snow on the road surface, which involves an algorithm module for deicing that at least needs to implement logic for identifying ice and snow conditions on the road surface, making deicing schemes based on the ice and snow conditions, such as which road segments need to be defrosted, which road segments need not be defrosted, whether salt spraying mode, salt spraying gram number, etc. are used, and automatic control of the deicing device in case of determining the deicing scheme.

The medical service vehicle is an automatic driving vehicle capable of providing one or more medical services, and the vehicle can provide medical services such as disinfection, temperature measurement, medicine preparation, isolation and the like, and the medical service vehicle relates to algorithm modules for providing various self-service medical services, wherein the algorithm modules mainly realize the identification of disinfection requirements and the control of disinfection devices so as to enable the disinfection devices to disinfect patients or identify the positions of the patients, control the temperature measurement devices to automatically measure the temperature of the patients at the positions of the forehead and the like of the patients, or realize the judgment of symptoms, give medicine according to the judgment result and need to realize the identification of medicines/medicine containers, control the medicine taking mechanical arm so as to enable the medicine taking mechanical arm to take medicines for the patients according to the medicine prescription, and the like.

The terminal service vehicle refers to a self-service type automatic driving vehicle capable of replacing some terminal equipment to provide certain convenience services for users, for example, the vehicle can provide printing, attendance checking, scanning, unlocking, payment, retail and other services for the users.

For example, in some application scenarios, users often need to go to a particular location to print or scan a document, which is time consuming and laborious. Therefore, there is a terminal service vehicle capable of providing a printing/scanning service for a user, the service vehicles can be interconnected with a user terminal device, the user sends a printing command through the terminal device, the service vehicle responds to the printing command, automatically prints a document required by the user and can automatically send the printed document to a user position, the user does not need to go to a printer for queuing, and the printing efficiency can be greatly improved. Or, the user can respond to the scanning instruction sent by the terminal equipment and move to the user position, and the user can finish scanning on the scanning tool of the service vehicle for placing the document to be scanned, so that queuing at a printer/scanner is not needed, and time and labor are saved. This involves an algorithm module providing print/scan services that at least needs to identify interconnections with the user terminal device, responses to print/scan instructions, positioning of user location, travel control, etc.

For another example, as new retail scenarios develop, more and more electronic commerce uses self-service vending machines to sell goods to various office buildings and public areas, but the self-service vending machines are placed in fixed positions and are not movable, and users need to go to the self-service vending machines before they can purchase the required goods, so that convenience is still poor. The self-service driving vehicles capable of providing retail services are arranged, the service vehicles can bear goods to automatically move, corresponding self-service shopping APP or shopping portals can be provided, a user can place an order to the self-service driving vehicles providing retail services through the APP or shopping portals by means of terminals such as mobile phones, the order comprises names, quantity and user positions of goods to be purchased, after receiving an order placing request, the vehicles can determine whether the current remaining goods have the goods purchased by the user and whether the quantity is enough, and under the condition that the goods purchased by the user are determined to be enough, the goods can be carried to the user positions automatically, and the goods are provided for the user, so that the convenience of shopping of the user is further improved, the user time is saved, and the user can use the time for more important things. This involves the algorithm modules providing retail services that implement mainly logic for responding to user order requests, order processing, merchandise information maintenance, user location positioning, payment management, etc.
