Description

The present invention can be set to any one of a plurality of security modes including a warning state in which security is performed based on an output from a detection unit that detects an abnormality in the security area and a warning release state in which security is not performed. A configured security device;
The present invention relates to a security system comprising: a security mode changing device configured to change the setting of the security mode of the security device.

  In a security system for security in a security area such as a general home or building, a mechanism for starting security is to incorporate a PIN code switch or card reader function in the controller and operate them. . The controller is often installed in the center of a living room, for example, in the case of ordinary households. For example, when going out in a warning state and releasing the warning when returning home, the controller must always go to the position where the controller is installed to release it. Is required.

  The warning state must be released within a certain period of time after the sensor installed at the entrance reacts.To reduce the risk of false alarms, the time can be lengthened. Due to the nature of, it is better that the time until the release operation is as short as possible. Therefore, there is a system in which the PIN code switch and the card reader are made independent and can be separately placed in a highly convenient place such as near the entrance. Specifically, as shown in Patent Document 1, when a user holds an RFID (Radio Frequency IDentifier) tag over a predetermined RFID reader, a signal is transmitted to a controller to which the RFID reader is connected, and a warning state is set. A system that can be changed exists.

  When a card reader is installed at the entrance in such a system, when a card used for security is registered in the controller, it is necessary to switch the controller to the registration mode and read the card to be registered by the card reader. That is, at the time of card registration, it is necessary to operate both the card reader and the controller. If the registration work is performed by one person, for example, it is necessary to go back and forth between the living room where the controller is installed and the entrance where the card reader is installed. Moreover, if it is going to reduce the effort of a round trip, registration work will be performed by two people.

  Another problem is that when a card reader is installed at the entrance, wiring work with the controller is required, which increases the construction cost. As another problem, in such a system, since the installation location of the card reader is fixed, for example, the card reader fixed to the entrance is fixed to the bedroom only for the purpose of setting the controller in the outing warning mode. There is a problem that the usage of the card reader is limited, for example, the card reader is used only for the usage set in the home security mode.

  In light of these issues, the applicants improve the portability of the card reader and increase its versatility by configuring the card reader to be wireless and performing wireless communication between the card reader and the controller. At the same time, we invented a system that increased the construction cost and usability of the security system.

JP 2009-093520 A

  However, there are the following points when the card reader is made wireless. In consideration of the convenience of the user, it is desirable to confirm whether the state of the detection means can be set to the warning state when setting the warning state using the wireless card reader. Therefore, an object of the present invention is to make it possible to confirm whether or not the state of the detection means can be set to a warning state. Furthermore, when the card reader and the controller communicate with each other by wire, it is possible to always confirm the state. However, when communicating wirelessly, if the constant confirmation is performed, the power consumption is large, and the card If there are a plurality of readers or there is a detecting means for performing wireless communication, there is a risk of interference. Therefore, another object of the present invention is to confirm whether or not the state of the detection means can be set to a warning state while avoiding constant communication.

  When performing registration at the time of installing a card reader or deleting registration for associating a controller and a card reader, it is necessary for an operator to go to the installation location of the controller and perform registration and deletion operations using a setting device.

  In addition, if the registration deletion operation is not performed when the card reader is removed, the following problem may occur. When the user wishes to remove the card reader, if the customer performs the operation of returning the card reader by the customer himself without performing the deregistration work at the site, the personnel / cost related to the deletion can be simplified. However, if the collected wireless reader is newly registered and used in a controller installed in the vicinity of the controller that was originally used, both the originally used controller and the newly registered controller will be used. There is a risk of simultaneous communication.

  As described above, when the card reader is removed, it is desirable to perform an on-site registration deletion operation. However, for this purpose, there is a problem that the human cost is increased in the operation of the security system. Therefore, another object of the present invention is to realize a security system that can be operated without work by local workers when removing a wireless operation device such as a card reader, and to reduce the human cost of the security system. Is to reduce.

  In order to achieve the above object, the characteristic configuration of the security system according to the present invention includes a warning state in which security is performed based on an output from a detection means for detecting an abnormality in the security area, and a warning release state in which security is not performed. A security device configured to be settable to any one of a plurality of security modes, and a security mode changing device configured to be able to change the setting of the security mode of the security device. The security mode changing device is configured to change the security mode of the security device using wireless communication, and a mode for transmitting a command to change the security mode to the security device. A change command means; and a security state acquisition means for acquiring from the security device a security status including change permission / inhibition information indicating whether the security mode can be changed in the security device. The security state is the security condition acquired by the acquiring means, when it is possible to change the security mode, in configured point to be able to change the security mode of the security device by the mode change command means.

  According to the above characteristic configuration, the security mode change device acquires a security state before a predetermined operation is performed on the activation unit and a command is sent to the security device to change the security mode by the mode change command unit. The changeability information indicating whether or not the security mode can be changed by the means can be acquired from the security device. In this case, for example, when the security device has a plurality of security modes such as an outing security mode and a home security mode as a security mode, by obtaining information on whether or not to change to each security mode, which one is changed by the security mode change device. It can be set as the structure which can select whether it changes into security mode. Further, for example, the security mode changing device is configured to output the obtained change enable / disable information externally (for example, output by sound, light, vibration, or notification to a user's mobile terminal). For example, before operating the mode change command means, the user can grasp whether the security mode can be changed by operating the mode change command means, and operate the mode change command means even though the security mode cannot be changed. It is possible to eliminate useless movements such as.

  Further, as a further characteristic configuration, unique identification information is set in the security mode changing device and the security device, and the security mode changing device stores one piece of identification information of the security device. The security device comprises security device-side storage means for storing at least one identification information of the security mode change device, and the security mode change device and the security device communicate with each other at the start of wireless communication. It is configured that the security mode of the security device can be changed from the security mode changing device only when mutual authentication is performed to check whether the identification information is stored and the mutual authentication is successful.

  According to the above characteristic configuration, the security mode changing device is configured to store only one piece of identification information of the security device that is the counterpart of the wireless communication. Further, only when the security mode changing device and the security device store each other's identification information, the mutual authentication succeeds, and the security mode of the security device can be changed from the security mode changing device.

  For this reason, for example, when removing a security mode change device configured to wirelessly communicate with one security device, the security device identification stored in the change device side storage means of the removed security mode change device By only changing or erasing information, mutual authentication between the security device and the removed security mode change device does not succeed, and the security mode of the security device cannot be changed from the security mode change device. That is, the communication between the security device and the removed security mode changing device can be prevented from being normally terminated without changing the security device-side storage means of the security device.

  Therefore, when the security mode change device is removed, there is no problem if the user of the security system simply returns the security mode change device to the operator of the security system as it is. No need to do work. As described above, when the security mode changing device using wireless communication is removed, it is possible to realize a security system that can be operated without any work by local workers, and to reduce the operation and maintenance costs of the security system.

  In the security system according to the present invention, in addition to the above-described characteristic configuration, it is preferable that the security device-side storage unit stores a plurality of identification information of the security mode changing device.

  According to the above characteristic configuration, the security mode can be changed with respect to one security device using a plurality of security mode changing devices. Therefore, it is possible to prepare a plurality of security mode changing devices for the security device and to use the security mode changing device properly for each place and application. Specifically, for example, it can be used in a bedroom or a living room in addition to the entrance. That is, it is possible to realize a security system that is highly convenient for the user while reducing the operation and maintenance costs of the security system.

  In addition, it is preferable that the security device includes an identification information changing unit for changing the identification information of the security mode changing device stored in the security device-side storage unit.

  According to the above characteristic configuration, by providing the security device with the identification information changing means, it is possible to easily change the identification information. Specifically, for example, when the security device is installed, it is not necessary for the worker to prepare equipment such as a setting device for changing the identification information of the security mode device separately stored in the security device-side storage means. Therefore, the operation and maintenance cost of the security system can be further reduced.

  Further, it is preferable that the mode change command means transmits a command to change the security mode to the security device when an information storage medium having unique identification information exists in a predetermined area.

  Further, as another characteristic configuration, the security mode change device is provided separately from the mode change command means, and an activation means for starting power supply from a power source by a predetermined operation, and the activation means When the predetermined operation is performed and power supply is started by the activation unit, the security state is acquired by the security state acquisition unit, and when the security mode can be changed, the mode change command unit After the security mode of the security device is changed, the power supply from the power source is terminated, and when the security mode cannot be changed, the intermittent operation control means for terminating the power supply from the power source, It is suitable to provide.

According to the above characteristic configuration, the power is supplied from the power source only when it is necessary to change the security mode of the security device after the intermittent operation control means performs a predetermined operation on the activation means. Therefore, unnecessary power consumption during the standby time when nothing is performed can be suppressed.
In addition, since the timing of performing wireless communication is limited, there is little risk of interference even when there are multiple security mode change devices or when there is a detection means that performs wireless communication, and a signal that is generated during interference Increase in the number of retransmissions can be suppressed. Specifically, it is possible to suppress interference with a signal transmitted every time a state change occurs by a periodic communication periodically transmitted from the detection means to the security device or a detection means such as a passive sensor. Thereby, the power consumption by the radio | wireless communication of a security mode change apparatus can be reduced.

As described above, the security mode changing device can confirm whether the state of the detection means can be set to the warning state while avoiding constant communication and suppressing power consumption. That is, it is possible to realize a security system with excellent convenience while suppressing power consumption.
In addition, in the said characteristic structure, when the portability of a security mode change apparatus is considered, it is suitable to use a battery as a power supply. In this case, in addition to the improvement of portability, the above-described characteristic configuration suppresses battery consumption and extends the operation time. Therefore, the battery replacement cycle becomes long, and the operation cost of the user can be reduced.

  Hereinafter, a security system S according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the security system S is configured to be able to detect various abnormalities in a predetermined security area A. More specifically, in the security area A, one or more detection means 20 connected to the controller 10 by wire or wireless using an electromagnetic method is installed. When detecting the abnormality, the detection means 20 is configured to output a signal indicating that the abnormality is detected to the controller 10. The controller 10 receives the output from the detection means 20 and performs security such as reporting to a monitoring center (not shown) managed by the operator of the security system S or issuing an alarm.

  As illustrated, the security system S includes a controller 10, one or more detection means 20, and a wireless reader 30. These devices are installed in the security area A as illustrated. Here, in this embodiment, the case where a general household is used as the security area A is shown. The controller 10 corresponds to a “security device” according to the present invention, and the wireless reader 30 corresponds to a “security mode changing device”.

  The controller 10 is installed in a living room, for example. As shown in FIG. 2, the controller 10 has a warning mode M1 for performing security based on an output signal indicating an abnormality from the detection means 20 for detecting an abnormality in the security area A, and a warning release mode M2 for performing no security. Can be set to any one of a plurality of security modes. In the alert release mode M2, the controller 10 temporarily stops the operation of the detection means 20, or does not process the output signal from the detection means 20, thereby entering a state where no security is performed. Here, the alert mode M1 corresponds to the “alert state” according to the present invention, and the alert release mode M2 corresponds to the “alarm release state”.

  Although not shown, the controller 10 is configured to be able to communicate with the monitoring center via a communication line such as a telephone line or the Internet. When the controller 10 detects an abnormality in the alert state, the controller 10 is configured to notify the user of the security system S or the monitoring server that the abnormality has been detected. When an abnormality is confirmed on the monitoring server side, measures such as dispatching a security guard to the security area A are taken.

  In the present embodiment, the controller 10 includes an external contact output terminal X. For example, when the security mode of the controller 10 is set to the security mode M1, the external contact output terminal X is configured to be able to control the operation of the device connected to the external contact output terminal X in conjunction with the external contact output terminal X.

  In order to detect an abnormality in the security area A, one or more detection means 20 are installed in the security area A where monitoring is considered necessary. The controller 10 is connected by wire or wireless. As the detection means 20, various sensors such as a human sensor, an infrared sensor, a passive sensor, and a magnet sensor for detecting illegal intrusion are used. Specifically, for example, opening / closing of a doorway or opening / closing of a window in the security area A is detected using a magnet sensor. Moreover, as the detection means 20, a fire alarm or a gas alarm for detecting an abnormality in the security area A can also be used. The detection unit 20 communicates with the controller 10 wirelessly or by wire. Hereinafter, information output from the detection unit 20 to the controller 10 is referred to as “alarm information”.

  The wireless reader 30 is configured to transmit and receive signals to and from the controller 10 by wireless communication. In the present embodiment, a plurality of wireless readers 30 are provided in the security area A, and are arranged, for example, in the vicinity of the entrance / exit of the security area A or in the bedroom. The wireless reader 30 is configured such that the security mode setting of the controller 10 can be changed by a user performing a predetermined operation. In the present embodiment, as shown in FIG. 4, the wireless reader 30 is configured to be able to read the RFID tag 40, and is configured to allow the user to change the security mode of the controller 10 by holding the RFID tag 40. Is done. As the RFID tag 40, for example, a non-contact type IC card can be used.

[Detailed configuration of equipment]
Hereinafter, detailed configurations of the controller 10 and the wireless reader 30 will be described with reference to the drawings.
1. Controller 10
As shown in FIG. 2, the controller 10 is connected to one or more detection units 20 by wire or wirelessly and is connected to one or more wireless readers 30 wirelessly. The controller 10 includes a control device 11, a storage device 12, and a communication control unit 14.

  The control device 11 includes an arithmetic processing device such as a CPU and a storage device such as a volatile memory, and is configured to perform various processes by controlling operations of the storage device 12 and the communication control unit 14. The storage device 12 is configured to be capable of storing information semi-permanently, such as a nonvolatile memory. The communication control unit 14 controls communication between the controller 10, the detection unit 20, and the wireless reader 30. Specifically, for example, an LSI for short-range wireless communication can be used. More specifically, it is preferable to use a specific low-power wireless standard for the communication method between the controller 10 and the detection means 20.

  Moreover, the controller 10 is provided with an operation button 13 for operating the controller 10 on the front surface. Specifically, the “registration button” used for the reader ID registration work, the block button to which the numbers “0” to “9” are assigned, the security mode of the controller 10 is the outing warning mode M1a, the home warning mode M1b. , Or a security mode setting button for setting one of the warning cancellation modes M2.

  The controller 10 is set with unique identification information (controller ID). In the present embodiment, the controller ID is set in advance at the manufacturing stage of the controller 10. The controller ID is stored in the storage device 12.

  Further, the controller 10 has an area in which one or more pieces of identification information (reader ID) set uniquely for each wireless reader 30 can be stored. The reader ID is stored in the storage device 12. In the present embodiment, the storage device 12 is configured to be capable of storing a plurality of reader IDs. The storage device 12 corresponds to a “security device-side storage unit” according to the present invention.

  In the present embodiment, in addition to the identification information of the wireless reader 30, the storage device 12 also stores identification information of various devices (wired reader and detection means 20) connected to the controller 10 in a wired or wireless manner. . That is, the controller 10 can simultaneously use a wired reader in addition to the wireless reader 30.

  The control device 11 includes a detection means confirmation means 110, a security mode setting means 111, a mutual authentication execution means 112, and an identification information change means 113. In the present embodiment, these means (110 to 113) are implemented as a program that operates on the control device 11.

  The detection means confirmation means 110 is configured to confirm whether the outputs from all the detection means 20 connected to the controller 10 are normal. Here, the determination of whether or not it is normal is determined by whether or not the detection means 20 is operating normally (whether or not it has failed) and whether or not the controller 10 can be shifted to the alert mode M1. The More specifically, “whether or not the controller 10 can be shifted to the alert mode M1” is determined, for example, by the detection unit 20 to determine whether a door or window that is a detection target is closed. As the detection means confirmation means 110, for example, a loopback function can be implemented between the controller 10 and the detection means 20, and it can be configured to determine whether or not a loopback test passes. Hereinafter, the confirmation result by the detection means confirmation means 110 (whether or not the outputs from all the detection means 20 are normal) is referred to as “loop information L” (FIG. 8). The “loop information L” corresponds to “change possibility information” according to the present invention, and is included in a “security state” described later.

  In the present embodiment, the controller 10 includes two types of modes, an outing warning mode M1a and a home warning mode M1b, as the warning mode M1. The “loop information L” sent from the controller 10 to the wireless reader 30 is configured by loop information corresponding to each alert mode M1. Specifically, the “loop information L” includes two types of “outing warning loop information” corresponding to the outing warning mode M1a and “home warning loop information” corresponding to the home warning mode M1b. .

  The outing warning loop information indicates whether or not the outputs of all the detection means 20 are normal in a state where the controller 10 is set in the outing warning mode M1a, that is, for example, a door or a detection target of the detection means 20 Indicates whether all windows are closed.

  The home warning loop information indicates whether or not all the outputs from the detection means 20 validated in the home warning mode M1b are normal. That is, it indicates whether a door or a window that is a detection target of the detection means 20 used for warning in the home warning mode M1b is closed.

  The security mode setting unit 111 sets the security mode of the controller 10. In the present embodiment, the warning mode M1 is configured to be selectable from two types: a going-out warning mode M1a and a home warning mode M1b.

  The outing warning mode M1a is used when the user needs security when going out. In this mode, when the controller 10 receives an output signal indicating that an abnormality has been detected from any of the detection means 20, it notifies the monitoring center or issues an alarm.

  The home security mode M1b is used when the user needs security while at home. This mode is used, for example, when the user goes to bed. In the home security mode M1b, the user can select which area in the security area A from which the output from the detection means 20 is valid. Specifically, for example, the setting can be made such that the detection means 20 in the building in the security area A is disabled and the detection means 20 relating to the intrusion route into the security area A from the outside is enabled.

  The warning cancellation mode M2 is mainly used when the user is at home and does not require security. In this mode, even if the controller 10 receives an output signal indicating that an abnormality has been detected from the detection means 20, the controller 10 does not report to the monitoring center or issue an alarm. That is, the output from the detection means 20 does not determine that an abnormality has occurred in the guard area A. In this mode, the output from the detection means 20 is not attributed to the intruder but is attributed to the user's own behavior.

  In the present embodiment, the controller 10 and the wireless reader 30 perform mutual authentication for confirming whether or not identification information of a communication partner is stored with each other at the start of wireless communication. The mutual authentication execution unit 112 performs processing necessary for the controller 10 in “mutual authentication”. Specifically, the reader ID of the wireless reader 30 transmitted from the wireless reader 30 is received, and it is confirmed whether the reader ID matches the reader ID as the connection destination ID of the wireless reader 30 stored in the storage device 12. If they match, the controller ID of the controller 10 stored in the storage device 12 is transmitted to the wireless reader 30. If they do not match, it is considered that mutual authentication has failed, and communication with the wireless reader 30 is terminated. Specifically, for example, processing such as forcibly terminating communication or notifying the wireless reader 30 that mutual authentication has failed is performed.

  The identification information changing unit 113 changes the reader ID as the connection destination ID stored in the storage device 12. That is, the controller 10 is configured to be able to rewrite the reader ID stored in the storage device 12 by the identification information changing unit 113 without separately preparing a dedicated register such as a PC. Specifically, the identification information changing unit 113 can newly register a reader ID in the storage device 12 or delete the reader ID stored in the storage device 12.

  The identification information changing unit 113 is configured to operate when a user operates a button provided on the controller 10. Here, the change operation of the reader ID is usually performed on the business owner side of the security system S. Therefore, the operation for operating the identification information changing means 113 is a special operation that the user cannot take during normal operation. Assign operations. Specifically, for example, in addition to the registration button provided in the controller 10, the identification information changing unit 113 is operated by an operation such as pressing a plurality of buttons that are not normally pressed simultaneously for a specified number of seconds or longer. Can be configured.

  With this configuration, when rewriting the reader ID stored in the storage device 12 of the controller 10, the reader ID registration of the wireless reader 30 can be performed only by the controller 10 without separately preparing a dedicated register. And can be deleted. Thereby, for example, when the controller 10 is installed, the worker can easily perform the registration work of the wireless reader 30. Therefore, the cost related to construction of the security system S can be reduced.

1-1. Operation Mode of Controller 10 Further, the controller 10 in the present embodiment is configured to be able to change the reader ID stored in the storage device 12 without using the identification information changing means 113. More specifically, as shown in FIG. 3, when the controller 10 performs a startup process after power-on, the controller 10 transitions to any one of “operation mode”, “PC registration mode”, and “one-touch registration mode”. Here, the “operation mode” is a mode in which the security of the security area A can be executed by communicating with the detection means 20, and the “PC registration mode” and the “one-touch registration mode” are stored in the storage device 12 of the controller 10. This is a mode for changing the reader ID.

  More specifically, the controller 10 is set to the alert mode M1 or the alert release mode M2 by the guard mode setting unit 111 when the controller 10 transits to the “operation mode”. In this embodiment, the outing warning mode M1a or the home warning mode M1b is used as the warning mode M1 as described above.

  In the “one-touch registration mode”, the reader ID can be changed by operating the identification information changing unit 113. In the “PC registration mode”, the reader ID can be changed using a dedicated register such as a PC.

  When the controller 10 is turned on, the controller 10 performs an operation check process at the time of startup, and then shifts to an “operation mode” that operates in the alert mode M1 or the alert release mode M2. Here, the controller 10 shifts to the “one-touch registration mode” by performing the above-described special operation in the alert cancellation mode M2. On the other hand, in the alert release mode M2, for example, by performing a registration operation such as pressing and holding a registration button provided on the controller 10 for a specified number of seconds or more, the mode shifts to the “PC registration mode”. In addition, it can transfer to "PC registration mode" by performing registration operation, after satisfy | filling a predetermined condition at the time of starting of the controller 10. FIG.

  As described above, by providing a plurality of modes, for example, when there is little necessary work for changing the reader ID, the one-touch registration mode is used. When it is necessary to perform a plurality of work for changing the reader ID, the PC registration mode is used. It is possible to select an efficient method according to the work content, such as using.

  In the PC registration mode, the controller ID of the controller 10 to be removed may be overwritten with the controller ID of the newly attached controller 10 when the controller 10 is replaced. By overwriting, the newly attached controller 10 and the existing wireless reader 30 are paired again, and the work of re-registering the reader ID in the newly attached controller 10 can be made unnecessary.

  The one-touch registration mode will be described in detail. In the one-touch registration mode, it is possible to register or delete the reader ID by operating the identification information changing unit 113 by operating the button of the controller 10.

  The one-touch registration mode starts when the controller 10 is in the operation mode and is in the alert release mode M2 by simultaneously pressing and holding the registration button and a predetermined key for a predetermined time or more. When the controller 10 shifts to the one-touch registration mode, for example, the controller 10 is configured so that it can be visually confirmed by a method such as blinking a lamp provided in the controller 10.

  In the one-touch registration mode, the mode is shifted to the operation mode by pressing the registration button again. Further, after the transition to the one-touch registration mode, it may be configured to shift to the operation mode when there is no operation for a predetermined time. Here, the predetermined time can be set to 10 minutes, for example.

1-2. Registration Method of Detection Unit 20 to Controller 10 In the one-touch registration mode, the controller 10 can register the detection unit 20 in addition to changing the reader ID. By pressing the block button for a predetermined time, the detection means registration pattern corresponding to the long-pressed number can be selected. As detection means registration patterns, “wireless detection means registration pattern”, which is a registration pattern of wireless detection means 20 connected to the controller 10 by wireless communication, and “wired detection,” which is a registration pattern of wired detection means 20. There are two types of “means registration pattern”.

  Here, the detection unit registration pattern is a setting of the detection unit 20 including a combination of the type of the detection unit 20, the installation location, and the communication method (one-way communication or two-way communication) in a state of being associated with the numbers 0 to 9. Is registered. That is, the detection means registration pattern is a set of 10 types of detection means 20 corresponding to numbers 0-9. The settings of the detection means 20 included in the detection means registration pattern correspond to numbers 0-9.

  In the present embodiment, two patterns can be set as the “wireless detection means registration pattern”. Specifically, for example, as a wireless detection means registration pattern, a detection means registration pattern that is selected when one or two block buttons are pressed and held is provided.

  When the detection unit registration pattern 1 or 2 is selected and a block button with a number corresponding to the setting of the detection unit 20 to be used is pressed among the settings included in the selected detection unit registration pattern, the corresponding block button Is turned on, and a standby state for waiting for a signal from the wireless detection means 20 is entered. When a signal requesting registration from the detection means 20 is received in the reception waiting state, the received detection means 20 is registered in the controller 10 with the setting of the detection means 20 selected by pressing the block button. At the time of registration of the detection means 20, a device number is assigned to the detection means 20. In the present embodiment, the smallest number to which the detection means 20 is not allocated is set as the device number.

  When the detection unit 20 cannot be registered in the reception waiting state, the state returns to the reception waiting state from the detection unit 20. Examples of the case where the detection unit 20 cannot be registered include a case where a signal requesting registration from the already registered detection unit 20 is received, or a case where there is no newly assigned device number.

2. Wireless reader 30
The configuration of the wireless reader 30 is shown in FIG. The wireless reader 30 is configured to communicate with the controller 10 wirelessly, and is configured to be able to change the security mode of the controller 10 when the user holds the RFID tag 40 over the wireless reader 30. In the present embodiment, the wireless reader 30 can change the setting to one of the outing warning mode M1a, the home warning mode M1b, or the warning release mode M2 depending on how the RFID tag 40 is held. A state in which the security mode of the controller 10 can be changed when the RFID tag 40 is held over the wireless reader 30 is hereinafter referred to as a “standby state”.

  Here, the RFID tag 40 corresponds to an “information storage medium” according to the present invention, and the front surface of the wireless reader 30 corresponds to a “predetermined area”. As the RFID tag 40 used by the user, a non-contact type IC card in which the RFID tag 40 is built, a mobile phone, a smartphone, or the like can be used. In the present embodiment, Felica (registered trademark), MIFARE (registered trademark), or the like may be used as the RFID tag 40.

  Whether or not a predetermined RFID tag 40 can change the security mode of the controller 10 via the wireless reader 30 is determined by whether or not the unique identification number of the RFID tag 40 is stored in the controller 10. . That is, the storage device 12 of the controller 10 stores the identification number of the RFID tag 40 that can be used for changing the setting of the security mode. In the present embodiment, the controller 10 is configured so that the identification number of the RFID tag 40 stored in the storage device 12 can be set by the user.

  The wireless reader 30 includes a control device 31, a storage device 32, and a communication control unit 34. The control device 31 includes an arithmetic processing device such as a CPU and a storage device such as a volatile memory, and is configured to perform various processes by controlling the operations of the storage device 32 and the communication control unit 34. The storage device 32 is configured to be capable of storing information semi-permanently, such as a nonvolatile memory. The communication control unit 34 controls communication between the wireless reader 30 and the controller 10, and specifically, for example, a short-range wireless communication LSI can be used. More specifically, it is preferable that the communication method between the controller 10 and the wireless reader 30 is the same as the communication method between the controller 10 and the detection unit 20 and a specific low power wireless standard is used.

  In the present embodiment, the wireless reader 30 uses a battery built in the apparatus as the power source 36 necessary for operation. The card reader unit 37 and the communication control unit 34 are intermittently supplied with power from the power source 36 under the control of the intermittent operation control unit 310. Since there is no need to connect a separate power source to the wireless reader 30 and the operation can be performed only by the wireless reader 30 alone, the portability is excellent. Therefore, for example, it is possible to perform operations such as bringing the wireless reader 30 to a bedroom or the like and setting the home alert mode M1b at bedtime. In addition, by placing the wireless reader 30 at hand, if there is a false alarm for the disaster prevention alarm, the disaster prevention alarm can be canceled on the spot without moving to the location of the controller 10.

  An appearance of the wireless reader 30 is shown in FIG. As shown in the figure, the wireless reader 30 includes an activation button 33, a confirmation signal output unit 35, a card reader unit 37, and an operation switching unit 38 on the front surface of the apparatus. The activation button 33 corresponds to “activation means” according to the present invention, and the card reader unit 37 corresponds to “mode change command means”.

  When the activation button 33 is pressed by the user, power is supplied from the power source 36 to each part of the wireless reader 30. In the present embodiment, a lamp provided on the front surface of the wireless reader 30 and a buzzer provided inside the wireless reader 30 are used as the confirmation signal output means 35. The card reader unit 37 is configured to read unique identification information set in the RFID tag 40 when the RFID tag 40 approaches within a predetermined distance.

  The operation switching unit 38 switches the operation mode of the controller 10 that is set when the user holds the RFID tag 40 over it. In the present embodiment, the operation switching unit 38 includes a DIP switch. The operation switching means 38 can switch the operation mode set when the RFID tag 40 is held immediately after the activation button 33 is pressed to the outing warning mode M1a or the home warning mode M1b. As shown in FIG. 6, the operation switching means 38 is configured to take two states, ON and OFF.

  In the present embodiment, the wireless reader 30 sets the operation mode of the controller 10 as follows: when the RFID tag 40 is held immediately after the activation button 33 is pressed (first operation procedure), after the activation button 33 is pressed and released, There are two ways of holding the RFID tag 40 while pressing the start button 33 again (second operation procedure). When the operation switching means 38 is ON, the home warning mode M1b is set in the first operation procedure, and the outing warning mode M1a is set in the second operation procedure. In the case of OFF, it is configured to be set to the outing warning mode M1a in the first operation procedure and to the home warning mode M1b in the second operation procedure.

  As shown in FIG. 5, identification information (reader ID) unique to each wireless reader 30 is set in the wireless reader 30. In the present embodiment, the reader ID is set in advance at the manufacturing stage of the wireless reader 30. The reader ID is stored in the storage device 32.

  Further, the storage device 32 of the wireless reader 30 stores only one piece of identification information (controller ID) of the controller 10 as a connection destination ID. The storage device 32 stores a controller ID of the controller 10 that permits communication with the wireless reader 30. The storage device 32 corresponds to a “change device-side storage unit” according to the present invention.

  The control device 31 includes intermittent operation control means 310, mutual authentication execution means 311, and guard state acquisition means 312. In this embodiment, these means (310-312) are mounted as a program which operates on the control device 11.

  The intermittent operation control unit 310 supplies power from the power source 36 to a necessary portion for a certain period of time after a predetermined operation is performed on the activation button 33, and suppresses power consumption of the wireless reader 30. More specifically, the intermittent operation control means 310 is configured to control the power supply to the locations (card reader unit 37 and communication control unit 34) used when changing the security mode of the controller 10.

  Specifically, the intermittent operation control means 310 starts power supply from the power source 36 to the card reader unit 37 and the communication control unit 34 when the activation button 33 is pressed by the user, When the change succeeds or fails, the power supply is terminated. Details of the control of the intermittent operation control means 310 will be described later in “5-1. Operation of Wireless Reader”. By performing such control, the wireless reader 30 can communicate with the controller 10 while suppressing power consumption. In addition, after a certain time has elapsed, power supply to the communication control unit 34 is cut off, so that power consumption can be suppressed. Thereby, the wireless reader 30 in the present embodiment can be used for a long period of time while using the battery for the power source 36.

  The mutual authentication execution unit 311 performs processing necessary for the wireless reader 30 in the mutual authentication performed when the wireless communication between the controller 10 and the wireless reader 30 is started. Specifically, the reader ID stored in the storage device 32 is transmitted to the controller 10 when communication between the controller 10 and the wireless reader 30 is started. Also, the controller ID transmitted from the controller 10 is received, and it is confirmed whether the received controller ID matches the connection destination ID stored in the storage device 32.

  If they match, it is determined that mutual authentication has succeeded, and bidirectional communication between the controller 10 and the wireless reader 30 is possible. After the mutual authentication is successful, communication for changing the security mode of the controller 10 is performed from the wireless reader 30.

  If they do not match, it is determined that mutual authentication has failed and communication with the controller 10 is terminated. Specifically, for example, the communication is forcibly terminated and power is supplied to the wireless reader 30, or the controller 10 is notified of the fact that the wireless reader 30 has failed mutual authentication. The controller 10 may also notify that the mutual authentication has failed.

  When the activation button 33 is pressed and power supply to each part of the wireless reader 30 is started and activated, the security status acquisition unit 312 acquires the security status set in the controller 10 at that time. In the present embodiment, the security status acquisition unit 312 detects the loop information L by the detection unit confirmation unit 110 of the controller 10 and the detection unit 20 such as a fire / gas / emergency / intrusion as a security state in addition to the security mode of the controller 10. Get alarm information from.

  The wireless reader 30 outputs the security mode of the controller 10 included in the acquired security status in a form that can be visually recognized by the user by the confirmation signal output means 35. In the present embodiment, after the information is received, the lamp as the confirmation signal output means 35 is configured to indicate the security mode by the color or the blinking state. With this configuration, the user can grasp the current security state before holding the RFID tag 40 over the wireless reader 30. That is, in the present embodiment, the wireless reader 30 is set in the controller 10 by the security state acquisition unit 312 when the activation button 33 is pressed when changing the security mode of the controller 10 by a user operation. Is configured to get the security mode.

[Operation of security system S]
3. Pairing of Controller and Wireless Reader In the following, the reader ID of the wireless reader 30 is registered in the storage device 12 of the controller 10 by the “one-touch registration mode” or the “PC registration mode”, and the storage device 32 of the wireless reader 30 is registered. A procedure for registering (pairing) the controller ID of the controller 10 will be described. If the registration button provided on the wireless reader 30 is pressed for a predetermined time while the wireless reader 30 is in a standby state, the confirmation signal output means 35 displays that the wireless reader 30 starts registration processing with the controller 10. In the present embodiment, the lamp provided as the confirmation signal output means 35 is lit red. Here, the registration button is usually provided at a place where the user cannot operate, for example, directly on the electronic circuit board of the wireless reader 30.

  In this state, when the registration button is released and a predetermined time elapses, the display of the external output means 15 disappears, and a signal requesting registration is transmitted from the wireless reader 30 to the controller 10 together with the reader ID of the wireless reader 30. Thereafter, a response including the controller ID is received from the controller 10. When receiving the reply, the wireless reader 30 registers the controller ID in the storage device 32 and displays the reception result by the confirmation signal output means 35.

  Specifically, when a notification indicating that the registration is successful is received as a response from the controller 10, the confirmation signal output means 35 displays a registration completion display, and then shifts to a standby state. In this embodiment, as a registration completion display, the lamp as the confirmation signal output means 35 is lit in red for 2 seconds, and a buzzer sounds. On the other hand, when the reply cannot be received, a registration failure display is performed and the process shifts to a standby state.

  FIG. 7 shows an example of a sequence diagram for registering the wireless reader 30 in the controller 10. After the registration button is pressed for 2 seconds, the lamp is turned on, and after 1 second from the release of the registration button, the lamp is turned off and a registration process is executed between the controller 10 and the wireless reader 30.

  Specifically, first, when the lamp is turned off, a signal including a reader ID of the wireless reader 30 and a request for registration is transmitted from the wireless reader 30 to the controller 10 (STEP 1). When the controller 10 receives the signal, the controller 10 stores the reader ID as a connection destination ID in the storage device 12 (STEP 2). Thereafter, a response indicating success or failure of registration and a controller ID is transmitted from the controller 10 to the wireless reader 30 (STEP 3). When receiving the response from the controller 10, the wireless reader 30 registers the controller ID included in the response in the storage device 32 (STEP 4). After the registration process, the wireless reader 30 turns on the lamp as the confirmation signal output means 35 for 2 seconds and sounds the buzzer for a predetermined time in order to display the reception result.

  Here, in STEP 4, if another controller ID is already stored in the storage device 32, it is overwritten.

  Note that it is preferable that the operator performs the registration work of the wireless reader 30 to the controller 10 while the worker carries the wireless reader 30 close to the controller 10 because one worker can perform the registration work.

4). Mechanism of Mutual Authentication As described above, when the wireless reader 30 is registered in the controller 10, communication between the controller 10 and the wireless reader 30 becomes possible. Here, in the present embodiment, when wireless communication is started, first, mutual authentication for confirming whether or not the identification information of communication partners is stored is executed.

  Specifically, when communication with the controller 10 is started, for example, when the RFID tag 40 is held over the wireless reader 30 after the activation button 33 is pressed, for example, the mutual authentication execution unit 311 first performs the controller 10 In response, the reader ID of the wireless reader 30 is transmitted. When the controller 10 receives the reader ID, the mutual authentication execution unit 112 confirms whether the reader ID is registered as the connection destination ID of the storage device 12.

  When the registration is confirmed, the controller ID stored in the storage device 12 is transmitted to the wireless reader 30 by the mutual authentication execution unit 112. If the registration is not confirmed, the subsequent communication is forcibly terminated and the power supply to the wireless reader 30 is stopped.

  When the wireless reader 30 receives the controller ID from the controller 10, the mutual authentication execution unit 311 confirms whether the received controller ID matches the connection destination ID of the storage device 32.

  If they match, it is determined that mutual authentication has succeeded, and subsequent communication from the wireless reader 30 to the controller 10 becomes possible. Specifically, the security mode of the controller 10 can be changed from the wireless reader 30. On the other hand, if they do not match, it is determined that mutual authentication has failed and no subsequent communication is performed. That is, for example, even if the RFID tag 40 is held over the wireless reader 30, if mutual authentication fails, the communication to the controller 10 is forcibly terminated, and the power supply to the wireless reader 30 is stopped. The security mode of the controller 10 is not changed.

5). Operation of Wireless Reader Hereinafter, an operation when the RFID tag 40 is held over the wireless reader 30 in a state where the controller 10 and the wireless reader 30 are paired will be described. In the following description, it is assumed that the mutual authentication is successful, and the description is omitted.

  In the present embodiment, the wireless reader 30 is configured to be able to set the security mode of the controller 10 by two procedures, a first operation procedure and a second operation procedure. Specifically, in the state where the controller 10 is set to the warning release mode M2, for example, when the first operation procedure is performed, the outing warning mode M1a is set, and when the second operation procedure is performed, the home warning mode is set. Set to M1b. In the present embodiment, the operation switching means 38 can replace the warning mode M1 set in the first operation procedure and the second operation procedure.

  In the first operation procedure, the security mode of the controller 10 is set by holding the RFID tag 40 after the activation button 33 is pressed. In the second operation procedure, after the start button 33 is pressed, the start button 33 is once released, and the RFID tag 40 is held while the start button 33 is pressed again, whereby the security mode of the controller 10 is set.

  In the present embodiment, when the controller 10 is set in the warning release mode M2, the outing warning mode M1a is set when the first operation procedure is performed, and the home warning mode M1b is set when the second operation procedure is performed. The That is, the case where the operation switching means 38 is set to OFF is shown. Further, when the controller 10 is set to the alert mode M1, when the first operation procedure is performed, the alert release mode M2 is set. Hereinafter, the procedure for setting the security mode of the controller 10 will be described.

5-1. Operation of Wireless Reader In describing the procedure for setting the security mode of the controller 10, internal processing in the wireless reader 30 when setting the security mode will be described. In addition, the control of power supply to the card reader unit 37 and the operation switching unit 38 by the intermittent operation control unit 310 will be described in detail. The intermittent operation control unit 310 is configured to supply power to the card reader unit 37 and the communication control unit 34 only at a necessary timing. FIG. 8 shows an example of internal processing in the wireless reader 30.

  FIG. 8 shows a case where the security mode of the controller 10 is changed by the second operation procedure when the controller 10 is in the warning cancellation mode M2 and the loop information L by the detection means confirmation means 110 is normal. That is, after the activation button 33 of the wireless reader 30 is once pressed and released, the RFID tag 40 is held over while the activation button 33 of the wireless reader 30 is pressed again, and the security mode of the controller 10 is set to the security mode M1. Shows the case.

  The operation switching means 38 shown in FIG. 5 switches whether the controller 10 is set to the outing warning mode M1a or the home warning mode M1b by the operation of FIG. When the controller 10 is set to the outing warning mode M1a, the outing warning loop information is used as the loop information L, and when the controller 10 is set to the home warning mode M1b, the home warning loop information is used.

  When the start button 33 is pressed, the wireless reader 30 first sounds a buzzer as the confirmation signal output means 35. Subsequently, the intermittent operation control unit 310 supplies power to the communication control unit 34, and requests and acquires a “security state” from the controller 10 via the communication control unit 34. More specifically, as the “security state” by the security state acquisition unit 312, in addition to the security mode of the controller 10, the loop information L (the outing warning loop information and the home security warning) by the detection unit confirmation unit 110 of the controller 10 Loop information), and request and acquire alarm information from the detection means 20 such as fire, gas, emergency, intrusion, etc.

  When receiving the “security state”, the wireless reader 30 cuts off the power supply to the communication control unit 34. That is, the intermittent operation control unit 310 supplies power to the communication control unit 34 from when the activation button 33 is pressed until the security state is acquired by the security state acquisition unit 312.

  Next, the intermittent operation control unit 310 supplies power from the power source 36 to the card reader unit 37. At the same time, the received guard state is output by the lamp and buzzer as the confirmation signal output means 35.

  When the RFID tag 40 is held over the card reader unit 37 of the wireless reader 30 in a state where the security state is displayed by the confirmation signal output unit 35, the fact that the RFID tag 40 has been read by the sound of the buzzer as the confirmation signal output unit 35 is indicated. Is output. After the output, the power supply of the card reader unit 37 is cut off. That is, the intermittent operation control unit 310 does not supply power to the communication control unit 34 while the card reader unit 37 is operated, and only supplies power to the card reader unit 37.

  Subsequently, the intermittent operation control unit 310 resumes power supply from the power supply 36 to the communication control unit 34. When the power supply is resumed, the wireless reader 30 transmits a command C including information on the alert mode M1 (outing alert mode M1a or home alert mode M1b) set in the controller 10 via the communication control unit 34. In the present embodiment, identification information of the RFID tag 40 held over is also transmitted.

  Although omitted in the figure, when receiving information on the alert mode M1 from the wireless reader 30, the controller 10 sets the received alert mode M1. Thereafter, the “warning state” is transmitted to the wireless reader 30. Here, as the “warning state”, in addition to the security mode of the controller 10, loop information L (outing warning loop information and home warning loop information) by the detection means confirmation means 110 of the controller 10, fire / gas / The alarm information from the detection means 20 such as emergency / intrusion and whether the held RFID tag 40 is valid are included.

  When the wireless reader 30 receives a warning state from the controller 10, the intermittent operation control unit 310 cuts off the power supply from the power source 36 to the communication control unit 34. That is, the intermittent operation control unit 310 supplies power to the communication control unit 34 from the power source 36 until the alert state is received after the command C is transmitted.

  When it is determined that the security mode of the controller 10 has been switched, the wireless reader 30 performs a security status confirmation display by the confirmation signal output means 35. Specifically, as the security state confirmation display, the buzzer is sounded and the lamp is lit in a different color for a predetermined time in accordance with the security mode. In this embodiment, the lighting time is set to 4 seconds.

  Note that the identification information of the RFID tag 40 held over is not registered in the controller 10 and is received from the controller 10 when the RFID tag 40 is determined to be invalid, or when the security mode included in the command C transmitted by the wireless reader 30 is received. When the security mode included in the selected security status does not match, the security status confirmation display is not performed. In this case, the confirmation signal output means 35 outputs that it is invalid. Specifically, for example, an output such as a buzzer beeping is performed.

5-2. Security Mode Setting by First Operation Procedure A series of operations when the RFID tag 40 is held by the first operation procedure will be described. In this case, first, when the start button 33 is pressed, the wireless reader 30 acquires the current security mode and loop information L (outing warning loop information and home warning loop information) from the controller 10.

  The wireless reader 30 confirms whether the acquired security mode is the warning cancellation mode M2 and the condition that the loop information L corresponding to the warning mode M1 set by the first operation procedure is normal is satisfied. When the condition is satisfied, the controller 10 can be set to the alert mode M1 by holding the RFID tag 40. When the condition is not satisfied, an error process described later is performed. Below, the setting of the security mode by the 1st operation procedure in this embodiment is demonstrated more concretely.

5-2-1. When the operation switching means 38 is set to OFF When the RFID tag 40 is held over the wireless reader 30 by the first operation procedure, the controller 10 is set to the outing warning mode M1a. Specifically, as shown in FIG. 9A, first, when the start button 33 is pressed, the lamp as the confirmation signal output means 35 of the wireless reader 30 is in the alert release mode M2 and goes out. Lights up in green indicating that warning loop information has been established.

  When the RFID tag 40 is held over in this state, a signal (command C) for setting the outing warning mode M1a is transmitted from the wireless reader 30 to the controller 10. When the setting is successful, the fact that the outing warning mode M1a has been set is transmitted from the controller 10 to the wireless reader 30, and the lamp as the confirmation signal output means 35 lights up in red indicating the outing warning mode M1a for 4 seconds. Thereafter, the lamp is turned off.

5-2-2. When the operation switching unit 38 is set to ON When the operation switching unit 38 is set to ON, when the RFID tag 40 is held over by the first operation procedure, the controller 10 performs the home alert mode M1b. Set to In this case, when the start button 33 is pressed, the lamp as the confirmation signal output means 35 of the wireless reader 30 is lit in green indicating that the alarm release mode M2 and the home alarm loop information are established. .

  When the RFID tag 40 is held over in this state, a signal (command C) for setting the home alert mode M1b is transmitted from the wireless reader 30 to the controller 10. When the setting is successful, the fact that the home security mode M1b has been set is transmitted from the controller 10 to the wireless reader 30, and the lamp as the confirmation signal output means 35 is lit in orange indicating the home security mode M1b for 4 seconds. Thereafter, the lamp is turned off.

5-3. Security Mode Setting by Second Operation Procedure A series of operations when the RFID tag 40 is held by the second operation procedure will be described. As in the case of the first operation procedure, when the start button 33 is pressed, the wireless reader 30 acquires the current security mode and loop information L (outing warning loop information and home warning loop information) from the controller 10. . Next, it is confirmed whether the acquired security mode is the warning cancellation mode M2 and the condition that the loop information L corresponding to the warning mode M1 set by the second operation procedure is normal is satisfied.

  When the above-described conditions are satisfied, the controller 10 can be set to the alert mode M1 by holding the RFID tag 40. When the conditions are not satisfied, an error process described later is performed. Below, the setting of the security mode by the 2nd operation procedure in this embodiment is demonstrated more concretely.

5-3-1. When the operation switching means 38 is set to OFF When the RFID tag 40 is held over the wireless reader 30 by the second operation procedure, the controller 10 is set to the home alert mode M1b. Specifically, as shown in FIG. 9 (b), when the start button 33 is pressed, the lamp as the confirmation signal output means 35 of the wireless reader 30 is in the warning release mode M2 and for going out warning. Lights up in green indicating that loop information has been established. Next, the start button 33 is once released, the start button 33 is pressed again, and the pressed state is maintained. Here, when the activation button 33 is pressed again and the home alert loop information is established, the lamp as the confirmation signal output means 35 continues to be lit in green. If the home warning loop information is not established when the start button 33 is pressed again, for example, an error indicator is displayed in orange on the lamp.

  When the RFID tag 40 is held over in this state, a signal (command C) for setting the home alert mode M1b is transmitted from the wireless reader 30 to the controller 10. When the setting is successful, the fact that the home security mode M1b has been set is transmitted from the controller 10 to the wireless reader 30, and the lamp as the confirmation signal output means 35 is lit in orange indicating the home security mode M1b for 4 seconds. Thereafter, the lamp is turned off.

5-3-2. When the operation switching means 38 is set to ON In this case, when the RFID tag 40 is held over the wireless reader 30, the controller 10 is set to the outing warning mode M1a. A description of the same parts as in the case of OFF will be omitted.

  Unlike the case of OFF, when the start button 33 is once released, the start button 33 is pressed again and the pressed state is maintained, and when the outing warning loop information is established, the confirmation signal output means The lamp as 35 continues to light green.

  Further, when the RFID tag 40 is held over, a signal (command C) for setting the outing warning mode M1a is transmitted from the wireless reader 30 to the controller 10. When the setting is successful, the fact that the outing warning mode M1a has been set is transmitted from the controller 10 to the wireless reader 30, and the lamp as the confirmation signal output means 35 lights up in red indicating the outing warning mode M1a for 4 seconds.

5-4. Release of alert The alert is released when the RFID tag 40 is held by the first operation procedure in a state where the controller 10 is set to the alert mode M1. Specifically, as shown in FIG. 10C, first, when the start button 33 is pressed, the lamp as the confirmation signal output means 35 of the wireless reader 30 is red indicating the outing warning mode M1a, or Lights orange to indicate the home alert mode M1b.

  When the RFID tag 40 is held over in this state, a signal (command C) for setting the alert release mode M2 is transmitted from the wireless reader 30 to the controller 10. When the setting is successful, the fact that the warning release mode M2 has been set is transmitted from the controller 10 to the wireless reader 30, and the lamp as the confirmation signal output means 35 is lit in green indicating the warning release mode M2 for 4 seconds. Thereafter, the lamp is turned off.

5-5. When there is an error, when mode change is not permitted, or when mode change fails When a non-registered card is held over or when a card is held over when the loop information L is not normal, communication related to transmission of command C is normal In the case where the error cannot be made, the confirmation signal output means 35 outputs an error message. Specifically, as shown in FIG. 10 (d), the buzzer beeps and the lamp blinks orange for a predetermined time.

  Note that nothing happens when a card reader unit 37 of the wireless reader 30 cannot be read (for example, just a magnetic card).

[Reuse of wireless reader]
As described above, the wireless reader 30 that can be used to change the security mode of the controller 10 is configured to be easily reusable in the security system S in another home in this embodiment. Yes. Hereinafter, this feature will be described.

  The wireless reader 30 in the present embodiment is configured to perform mutual authentication with the controller 10 at the start of communication and to store only one controller ID as a connection destination ID in the storage device 32 of the wireless reader 30. For this reason, when the wireless reader 30 is re-paired with another controller 10, the controller ID stored in the wireless reader 30 changes and mutual authentication with the original controller 10 becomes impossible. Therefore, the wireless reader 30 in which the new connection destination ID is stored does not affect the original controller 10 without changing the connection destination ID stored in the original controller 10. 10 can be communicated.

  An example of handling the wireless reader 30 in a situation where the wireless reader 30 is actually reused will be described. When the wireless reader 30 according to the present embodiment is used, when the wireless reader 30 used in one security system S becomes unnecessary, the user of the security system S gives the operator of the security system S.
