Description

  The present invention belongs to the technical field of security keys used for security management (mainly locking and unlocking) of an air compressor and an air compressor management method using the security key.

  An air compressor is generally known as an apparatus for generating compressed air, and is used for nailing work at a construction site or the like.

  For example, the air compressor disclosed in Patent Document 1 includes a compression device that generates compressed air and an air tank that stores the compressed air. The compression device is placed and fixed on the air tank while being covered with a cover. The air tank that supports the compression device is generally composed of two cylinders and is arranged in parallel.

  Many of this type of air compressor is configured as a portable device, and has a design that takes into account a certain degree of portability, such as a hand-held handle for carrying. Such air compressors are widely used in construction sites and construction sites that require nailing work because of their high functionality.

JP 2010-096141 A

  As mentioned above, air compressors are widely used in sites that require nailing work, etc., but many of these construction sites and construction sites have low security, and people other than those involved in construction (for example, theft) The target person or the suspicious person can often go in and out relatively easily. For this reason, portable air compressors that are easy to carry and high-priced work equipment are particularly susceptible to theft by thieves, and theft for resale purposes is unending. Damage has been reported. (Because it has the features of “easy to carry” and “high price”, it has a much higher probability of being stolen than other tools and equipment.) Especially, it was left on the spot during breaks such as lunch breaks and at night. If left untouched, there is often a problem that the probability of theft becomes extremely high because there are often fewer people around the site.

  Although air compressors are considered to be easy to carry to some extent, even general ones weigh between 16 kg and 20 kg, so they are often left as they are during breaks. In other words, it is extremely cumbersome and heavy labor to carry and store the air compressor in a warehouse or mobile vehicle every time you leave the site, so even if the worker temporarily leaves the site temporarily due to a break etc. In many cases, they are left as they are. Also, depending on the worker, taking out after work is troublesome, and it may be left unattended on the spot until the next day.

  Therefore, as a measure to prevent theft of air compressors that are particularly susceptible to theft at the work site, a lock mechanism that can be unlocked with a key is attached to the air compressor (so that the compressor can be operated only when a physical key is inserted and unlocked) To prevent the removal or theft of equipment by persons without keys.

  However, such a security means has a problem that the anti-theft effect can hardly be expected because the compressor can be easily operated if the lock mechanism is removed after being taken away.

  In addition, this type of key (air compressor key) is much less portable than mobile phones and other valuables, so it is not portable when it is left at home or left behind in a company or mobile vehicle. There are many cases. In such a case, a fatal problem arises that the air compressor cannot be used at the work site, and the nailing operation or the like is forced to be stopped.

  Furthermore, when a small number of keys are reused by a plurality of workers, the management becomes extremely complicated, and as the number of workers increases, the key management is likely to be appropriate, and the risk of loss is extremely high. Become.

  Furthermore, if the key is lost, it cannot be dealt with on the spot, and it is necessary to request a reissue of the key from a dealer or manufacturer. Such reissuance of a key generally takes several days to several weeks, and thus there is a problem that it is necessary to stop the work or prepare an alternative device until the key arrives at hand.

  Such a keyed air compressor is provided with a plurality of keys including a spare key from the beginning. It is also possible to make a plurality of spare keys in preparation for loss after purchasing an air compressor. Therefore, by lending such a spare key to a plurality of workers (planned users of air compressors) in advance, even if one of them loses or misplaces the key, work can be started immediately. It is also possible to keep it.

However, when the key is left lent to each of a plurality of workers, the management becomes very complicated and the security of the air compressor is weakened.
For example, if one of the workers loses a key and leaves the situation of the loss, the air compressor is exposed to the risk of theft (taken away by the person who picked up the key) Risk).
Also, for example, if any worker retires and fails to collect the key, the air compressor is exposed to the risk of theft (risk of being taken away by the retired person).
Also, for example, it is impossible to deny the possibility that one of the workers duplicates the spare key indefinitely and gives it to others. In that case, it becomes difficult for the administrator to grasp the owner of the key without omission, It can be said that the function as security is already lost.

  Therefore, the air compressor with a key as described above has a problem that the anti-theft effect is poor, the key is easily lost and easily misplaced, and the management of the key itself is extremely complicated, and the security of the air compressor There is a problem of weakening.

  Therefore, in view of the above-described problems, the object of the present invention is to make it possible to easily and surely perform advanced security management for an air compressor that is particularly easily stolen at the work site, and to leap the anti-theft effect of the air compressor. It is an object to provide a new security means that can increase the security level and facilitate the management of security keys.

Such a purpose is a security key for turning ON / OFF the security of the air compressor, which is composed of a seal-type non-contact IC tag that can be attached to any possessed item of the compressor user. This is achieved by an air compressor security key comprising an IC chip on which readable unique identification information is recorded.
This security key can be used to turn on or off one or more air compressors with a single key.
In the present invention, the “unique identification information readable by the compressor” may be, for example, a unique ID code assigned and recorded at the time of manufacturing the non-contact IC tag, It may be unique key information written in the contact IC tag. That is, the identification information referred to in the present invention includes all unique information that can identify the contactless IC tag.

  Further, the above object is achieved by a security key seal set including a plurality of seal-type non-contact IC tags forming the security key described above, each having unique identification information recorded therein.

  The above object is achieved by an air compressor that includes a communication unit that performs short-range wireless communication with the above-described security key and has a security management device that performs security ON / OFF based on the communication result. In this air compressor, not only one security key but also a plurality of security keys of the present invention can be registered.

Also, the above object is to register security key identification information (for example, a unique ID code) in a security management device of an air compressor, and a non-contact IC tag forming the security key is pasted to any possessed item of the user. And an air compressor management method comprising the steps of:
Alternatively, the identification information (for example, unique key information) is written in the security key, the identification information is registered in the security management device of the air compressor, and the user has any contactless IC tag that forms the security key. And affixing the product to a product, the air compressor management method comprising:

In addition, the object is to individually register security key identification information (for example, a unique ID code) in each security management device of a plurality of prepared air compressors, and a non-contact IC tag forming the security key to a user. And affixing to any personal belongings of the air compressor management method.
Alternatively, a step of writing identification information (for example, unique key information) in the security key and individually registering the identification information in each security management device of a plurality of prepared air compressors, and contactless forming the security key And affixing the IC tag to any possession of the user.
Thus, by registering identification information of one security key in a plurality of air compressors, a plurality of air compressors can be used properly with one key as shown in FIG. In addition, since it is not necessary to have a plurality of keys corresponding to each of the plurality of air compressors, the conventional troublesome key management becomes unnecessary.

In order to unlock security with this management method,
Requesting ON / OFF of security for air compressor (arbitrary compressor when there are multiple units);
Performing near field communication between the security key in a state affixed to the user's personal belongings and the security management device, and reading identification information of the security key;
Executing the requested security ON / OFF when the read identification information is registered on the air compressor side.

  In this method, when invalidating the function of the security key registered in the air compressor, the registration of the identification information of the security key is canceled on the compressor side.

  The security key of the present invention is an electronic key for turning on / off (locking / unlocking) the security of the air compressor, and is a seal-type super key used in a state of being affixed to any possessed item of the compressor user. It consists of a small non-contact IC tag. The possessed items (objects to which the non-contact IC tags are attached) here are not particularly limited, and all items possessed by the user are targeted, but preferably individual items such as mobile phones, licenses, watches, wallets, accessories, etc. It is desirable to have a high portable awareness in the daily life of the user and a low possibility of misplacement or loss. And the possession which attaches a non-contact IC tag can be arbitrarily determined by individual user's judgment. That is, the security key can be freely attached to any item that the user desires.

  As described above, by configuring the security key with a non-contact IC tag, the key itself can be significantly downsized (miniaturized). And it becomes possible to affix on any possession of a user freely by reducing in size and comprising in a seal shape. As a result, each user can add a security key to an article with high mobile awareness (for example, a mobile phone, a license, a wallet, etc.) at his / her discretion. Therefore, according to the present invention, it becomes possible for a user to add a function of a key to an article that he / she desires desirable (an article having a strong user's sense of carrying). The concept of “owning an independent item” can be eliminated. Therefore, according to the present invention, as compared with a normal plug-in key or card key, a special effect that the possibility of loss, misplacement, or non-carrying of the key becomes extremely low is achieved.

  Further, by configuring the security key with a non-contact IC tag as in the present invention, it is easy to prevent a worker assigned with the security key from duplicating the key without permission.

  In addition, by providing a seal set with a plurality of non-contact IC tags that form such a security key, the required number of security keys can be issued simply and quickly to those who wish to use the compressor when necessary. become able to.

  Further, in the air compressor management method of the present invention, the non-contact IC tag functions as a security key simply by registering the identification information of the non-contact IC tag in the security management device of the air compressor. And you can easily prepare as many spare keys as you need.

  Also, according to the present invention, when one air compressor is used by a plurality of users as shown in FIG. 3, it is possible to easily assign a security key to each user. As a result, since the same key is not reused between workers as in the prior art, it is possible to prevent weakening of security caused by it.

  According to the present invention, as shown in FIG. 4, one non-contact IC tag can be used as a security key for a plurality of air compressors. As a result, even when a plurality of air compressors are used properly, the ON / OFF operation can be performed with one security key, and it is not necessary to possess a plurality of keys, so management of the security key is facilitated. Also, when using multiple air compressors, it is not necessary to find the corresponding key from among similar keys, so security ON / OFF operations can be completed quickly.

  In the present invention, security key identification information is registered in the air compressor, whereby the security of the air compressor can be centrally managed. That is, since identification information and the number of effective security keys registered in the air compressor can be grasped, the management of security keys is unified and facilitated.

  Further, in the present invention, only the security key whose identification information is registered on the air compressor side can be used to cancel or reset the security of the compressor. Therefore, the anti-theft effect can be drastically enhanced as compared with general air compressors conventionally used.

  In the present invention, the function as the security key can be invalidated by canceling the registration of the security key on the air compressor side. According to such a feature, when the user loses his / her security key or retires, the corresponding security key can be invalidated with a simple operation. Further, when performing such deregistration, it is not necessary to collect the security key, so the management of the security key is simple.

  Further, according to the present invention, even when a security key is individually assigned to each of a large number of workers, it is possible to easily confirm who assigned the security key at any time, and if necessary, the security key Can be invalidated (deregistered), so there is no risk that the security of the air compressor will be weakened.

(Overview of system configuration)
FIG. 1 shows a schematic configuration of an air compressor management system using the security key of the present invention.

  This management system includes an air compressor that generates compressed air (hereinafter abbreviated as “compressor”) and a seal-type non-contact IC tag for turning on / off the security of the compressor. “ON” of security means that the compressor is electronically locked so that the compression device of the compressor cannot be driven, or a state in which it is locked as such. “OFF” of security means unlocking so that the compression device of the air compressor can be driven, or a state in which it is unlocked.

  As shown in FIG. 1, the compressor has a security management device that performs security control and security management of the compressor in addition to a compression device that generates compressed air. This security management device is provided with an NFC module (communication means) for short-range wireless communication with a non-contact IC tag that forms a security key.

  A seal-type non-contact IC tag (hereinafter abbreviated as “seal tag”) functions as a security key for turning on / off the security of the compressor. This seal tag includes an IC chip in which identification information, which is a unique ID code, is recorded, and is used in a state of being affixed to a compressor user's belongings (such as a mobile phone).

  Details of the compressor and the security key will be described below.

(compressor)
The compressor is a device for generating compressed air, and mainly includes a compression device that plays a role of generating compressed air, and a security management device that performs security control and security management of the compression device.

  The compressor has a motor that drives a piston for generating compressed air, and an MCU that controls the motor and that is a control means for transmitting and receiving control signals to and from the MCU on the security management device side. doing.

  The compressor security management device includes an information display unit for displaying various guidance and security information, a switch or LED as an I / O unit, an NFC module (communication unit) for performing near field communication with a seal tag, It has MCU etc. which control each said part. Specific examples of the information display unit on the compressor side include, for example, a 7-segment display, LED, liquid crystal display, and organic EL display. The I / O means is not limited to the switch and the LED, and other I / O means such as an input touch panel and a speaker for outputting a warning sound can be employed.

  An NFC module (Near Field Communication Module) is a communication means for performing near field communication with a seal tag, and functions as a reader / writer for the IC chip of the seal tag. This NFC module includes an antenna for performing short-distance wireless communication with a seal tag, a controller that transmits instructions for reading and writing information on the seal tag, and the like.

  Numbers, alphabets, and the like can be displayed on the information display unit, and various guidance, security information, and the like are simply displayed according to the state and operation status of the device. For example, when an alarm due to an erroneous operation or malfunction occurs, simple guidance indicating an error such as “E1” or “E2” is displayed. If the user is familiar with the device, the contents of the simple display are displayed. It becomes possible to grasp the fact and contents of the alarm.

  The MCU of the security management device includes a memory for recording various information, and transmits and receives control signals to and from the compression device side MCU. In addition to the ID code of the seal tag, the user name and user number of the seal tag are recorded in the MCU memory as necessary. These ID codes and user names corresponding to the ID codes are recorded in the MCU while being associated with each other. Thus, by registering the ID code of the seal tag in the MCU, it becomes possible to make the seal tag function as a security key for the compressor.

  The main role of the MCU of the security management device is to perform security key authentication when wirelessly communicating with a seal tag, for example, and permit the locking and unlocking of the device only when the authentication is successful Etc.

  When operating the compressor having the above-described configuration, the security key registered on the compressor side is held near (by touching or approaching) the NFC module of the security management device. As a result, short-range wireless communication is automatically executed between the compressor and the seal tag, the ID code of the seal tag is read, and unlocked after passing the authentication of the security key so that the compression device can be driven.

(Security key / Seal tag)
The security key of the present invention is an electronic key mainly for turning on / off the security of the compressor, and is composed of a seal-type non-contact IC tag (wireless IC tag). The seal tag that forms the security key is used for wireless communication with a small IC chip in which a unique ID code (unique identification information / unique ID that does not overlap with other seal tags) that can be read by the compressor is recorded, and the NFC module on the compressor side. It has a small antenna to do. The ID code recorded in the IC chip is read out when performing wireless communication with the NFC module on the compressor side, transmitted to the NFC module, and used for authentication or the like in the security management apparatus.

  In the present invention, security key identification information used for security ON / OFF is not particularly limited. For example, a unique ID code assigned to the tag at the time of manufacture of the seal tag is used for security authentication. It can be used as identification information. Alternatively, identification information (key information) for security authentication can be written from the compressor side to the IC chip of the seal tag and registered in the MCU of the compressor, and this identification information (key information) can be used for security authentication thereafter. All of these ID codes and key information are included in specific examples of identification information for security authentication.

  The seal tag having the above-described configuration that functions as a security key is used by being affixed to any personal belongings such as a cellular phone of a compressor user. The personal belongings here are not particularly limited, and any item possessed by the user can be affixed, but preferably individual users such as mobile phones, smartphones, licenses, wallets, wristwatches, jewelry, home keys, etc. It is desirable to have a high portable consciousness in daily life and a low possibility of misplacement or loss. And the possession which affixes a seal tag can be determined freely by judgment of each user. That is, the seal tag can be freely affixed to any article that is desired by the user (an article that is assumed to be possessed when the compressor is used). The “user” here is not limited to the owner or manager of the compressor, but includes a person who simply uses the compressor at the work site.

  Such a seal tag may be provided alone, but may be provided in the form of a seal set including a plurality of seal tags, for example, as shown in FIG. Moreover, such a seal tag may be enclosed at the time of sale of a compressor, or may be provided to a user by another route.

  In this seal set, a unique ID code is assigned to each seal tag, and each seal tag is detachably attached to the mount. Each sticker tag is coated with an adhesive on the back side, and can be peeled off from the mount and attached to any user possession (in the illustrated example, the back side of the mobile phone) as shown on the right side of FIG.

  Hereinafter, a compressor management method using the compressor having the above-described configuration and a security key will be described in detail.

(Example of processing when registering security key ID code in the compressor)
In order to use the seal tag having the above configuration as a security key for the compressor, first, the ID code is registered on the compressor side. Hereinafter, a processing example when registering the ID code of the seal tag in the compressor will be described with reference to FIG.

  At the same time as the power is turned on, the compressor is on standby in a security ON state (a state in which the compression device is locked so that it cannot be driven and security is valid) <step S101>. When the security management device of the compressor is set to the security key registration mode <S103>, the security management device is requested to register the security key, and then the security management device waits in the seal tag ID code request state. Start <S105>.

  Subsequently, the seal tag is held near (touched or brought close to) the NFC module of the compressor security management device, and short-range wireless communication is performed between the two. By this short-range wireless communication, the ID code is read from the IC chip of the seal tag, and at the same time, the ID code is wirelessly transmitted to the compressor side <S107>. The ID code is identification information unique to the seal tag and does not overlap with other seal tags.

  Subsequently, the compressor security management device issues a management code such as a serial number or a user number <S109>, and then associates the ID code read in step S107 with the management code as exemplified in Table 1. Record in the MCU of the security management device <S111>. By recording in association with the ID code and the management code as shown in Table 1, even if the number of registrations of the ID code increases, the management and grasping are facilitated.

  Through the above processing, the security key registration processing is completed. When the registration process is completed, it is affixed to any possessed item of the user (preferably a possessed item such as a mobile phone or a license with high mobile awareness and low possibility of loss or misplacement). The article to be affixed is not particularly limited, and can be freely affixed to an object that each user desires.

  By repeating such registration processing for a plurality of seal tags, a plurality of security keys can be registered in one compressor as shown in FIG. Since each security key is given unique identification information (ID code in this embodiment), even when a plurality of security keys are registered, it is possible to individually cancel the registration. . The procedure for deregistration will be described later.

  In this embodiment, after the ID code of the seal tag is registered on the compressor side, the seal tag is affixed to the user's belongings, but this order may be reversed.

  In the embodiment illustrated in FIG. 5, the case where the ID code of one seal tag is registered in one compressor has been described. However, a plurality of compressors having the above-described configuration are prepared, and the same registration process is performed on these compressors. However, it is also possible to use one seal tag as a security key for a plurality of compressors. (Note that registration processing may be performed for a plurality of compressors at once, or the number of registrations may be increased sequentially as necessary.) As shown in FIG. Since a single seal tag can be used for multiple compressors, security key management becomes easy.

  Further, although not particularly limited in the above-described embodiment, it is also possible to limit a person who can perform such a seal tag registration process to a certain person. For example, a security authentication step may be interposed between steps S103 and S105 so that the security key can be registered only when authentication is passed. Such an authentication process is performed, for example, between a non-contact IC card for managers (a security card dedicated to the compressor manager) on which predetermined identification information bundled with the compressor is recorded and a security management device for the compressor. It can be carried out.

  In the embodiment shown in FIG. 5, the management code is automatically generated on the compressor side and associated with the read ID code. However, as shown in step S110 of FIG. It may be determined and input to the compressor side. For example, a user name of a seal tag to be registered may be input, and this user name may be associated with an ID code as shown in Table 2 as a management code. Other specific examples of management codes that can be entered include serial numbers and dates. As described above, the management and understanding of the ID code is further facilitated by recording the arbitrary management code determined by the user in association with the ID code.

  As another modification, information (authority information) regarding the authority to use the compressor may be input, and the authority information may be associated with the ID code and registered on the compressor side. As such authority information, for example, as shown in Table 3, there are the number of times it can be used, time, period, and the like. As a result, the function as the security key is automatically disabled after the specified number of times, time, and period are exceeded, so that it is not necessary to bother to collect the security key, and security management is further simplified.

(Processing example when the user starts using the compressor)
When the user uses the compressor, it is necessary to remove the security. Hereinafter, based on FIG. 7, an example of security release processing when the user starts using the compressor will be described.

  At the same time as the power is turned on, the compressor is on standby in a security ON state (locked so that the compression device cannot be driven and security is valid) <Steps S201 and S203>. When the security management device of the compressor is set to the security release mode <S205>, the security management device is requested to release the security, and then the security management device starts waiting in the seal tag ID code request state <S207 >.

  Subsequently, the seal tag is held near (touched or brought close to) the NFC module of the compressor security management device, and short-range wireless communication is performed between the two. By this short-range wireless communication, the ID code is read from the IC chip of the seal tag, and at the same time, the ID code is wirelessly transmitted to the compressor side <S209>.

  Subsequently, the security management apparatus of the compressor executes authentication for the read ID code. In this authentication process, it is determined whether or not the ID code of the seal tag that communicated this time is registered on the compressor side <S211>. If it is determined that the ID code is registered in the MCU and the ID authentication is successful, the security release of the compressor is executed in response to the security release request in step S205 <S213>. Thereafter, until the security is reset, it can be freely operated in the same manner as a conventional compressor.

(Processing example when resetting compressor security)
FIG. 8 is a flowchart showing a processing example when the user returns the security setting to the ON state (locked state) again after the use of the compressor is finished. Since this process is the same as the security release process shown in FIG. 7 except that the request for the compressor is changed to “security reset (locking)”, detailed description is omitted.

(Processing example when disabling security key)
In the present invention, when a user with a security key leaves or the security key itself is lost, the function can be easily disabled on the compressor side without collecting the security key. Hereinafter, based on FIG. 9, a processing example when invalidating the function of the security key registered on the compressor side will be described.

  At the same time as the power is turned on, the compressor is on standby in a security ON state (locked so that the compression device cannot be driven and security is valid) <steps S401 and S403>. When the security management device of the compressor is set to the security key invalidation processing mode <S405>, a management code (serial number or user name) as shown in Table 1 or Table 2 is displayed on the information display section <S407>. > The operator is requested to select a management code to be invalidated.

  Subsequently, when the operator selects a management code to be invalidated <S409>, the corresponding ID code is deleted from the MCU of the security management device <S411>. As a result, the ID code of the seal tag is deleted from the compressor, and thereafter the seal tag does not function as a security key for the compressor.

  The security key revocation process is completed through the above processes.

  In addition, although it does not specifically limit in embodiment mentioned above, it is also possible to limit the person who can perform the invalid process of such a security key to a fixed person. For example, a security authentication step may be interposed between steps S405 and S407 so that the security key registration can be canceled only when authentication is passed. Such authentication processing is performed, for example, between a manager's wireless IC card (a security card dedicated to the compressor manager) on which predetermined identification information bundled with the compressor is recorded and a compressor security management device. be able to.
