An embodiment of the present invention will be described below with reference to the drawings.
(Outline of storage system)
FIG. 1 is a perspective view of a storage system 1 according to this embodiment.
The storage system 1 includes a plurality of storage boxes 10-1, 10-2,..., 10-N (N is a positive integer). In the example shown in FIG. 1, the storage boxes 10-1, 10-2,..., 10-N are arranged side by side in two rows. Hereinafter, the storage cases 10-1, 10-2,... 10-N will be referred to as the storage case 10 unless particularly distinguished. The storage case 10 includes a door capable of closing a storage space provided inside the storage case 10. Further, the storage system 1 includes the electric lock control system 100, and the user can restrict the opening and closing of the door of each storage 10 by the electric lock control system 100.

FIG. 2 is a block diagram showing the configuration of the electric lock control system 100.
The electric lock control system 100 includes one master device 70 and a plurality of slave devices 80-1, 80-2,..., 80-N (N is a positive integer). Hereinafter, the plurality of slave units 80-1, 80-2,..., 80-N will be referred to as slave units 80 unless otherwise distinguished. The cordless handset 80 includes a lock portion 83 that is an electric lock, and controls locking/unlocking of the lock portion 83 provided in each storage case 10. Further, the master device 70 acquires various information from the authentication medium. Here, as an example, a case where the non-contact IC card 50 is adopted as the authentication medium will be described. The card 50 stores an address, a master device ID (IDentifier), a command, and update data. Of these, the master ID is used to authenticate the card 50.

The address is identification information corresponding to each storage case 10. That is, the address is the identification information corresponding to the lock part 83 of each storage case 10 and the slave unit 80 that controls the lock part 83. In this embodiment, there are two types of addresses: individual addresses and common addresses. The individual address is an address individually set for each storage 10. Basically, the individual address is set to a different value for each storage case 10. However, the same value may be set as the individual address of the plurality of storage boxes 10. The common address is an address common to all the storage boxes 10 included in the storage system 1. Hereinafter, the card 50 storing the individual address will be referred to as an individual card, and the card 50 storing the common address will be referred to as a common card.

The base unit ID is identification information unique to the base unit 70. In the present embodiment, as an example, the master ID includes the identification information (building ID) of the building in which the master is installed, the floor identification information (floor ID), and the group identification information (group ID). Is described. That is, the master ID is location information corresponding to the installation location of the electric lock control system 100. The master ID is used for authenticating the card 50.
The command is information indicating an instruction to the child device 80. The command includes, for example, an unlocking instruction, an unlocking holding instruction (continuous unlocking), a locking instruction, and the like, and the slave device 80 controls the operation of the lock unit 83 according to the command. Further, the command may instruct a change in state such that a lock instruction is given in the unlocked state, and an unlock instruction is given in the locked state.

The update data is information indicating the number of issued cards 50 for each storage 10. The update data is used to manage the validity of the card 50. For example, the value of the update data of the card 50 issued first is “00”. Then, according to the loss of the card 50 or the change of the user, a new card 50 is issued and the value of the update data is incremented by one. Then, the master device 70 does not accept the update data card 50 having a smaller value than the update data value managed by the master device. As a result, the master device 70 can invalidate the old card 50 in response to the issuance of the new card 50.

The card 50 may store identification information unique to the card 50 (card ID) and identification information unique to the user (user ID), in addition to the address, the master ID, and the command. However, as described later, the electric lock control system 100 can control locking/unlocking of the lock unit 83 without using the card ID or the user ID.

The outline of the operation of the storage system 1 will be described.
In locking and unlocking the storage 10, the user presents the card 50 to the master device 70. The master device 70 reads the address, the master device ID, and the command from the card 50. The master device 70 verifies the master device ID read from the card 50 with the master device ID of the self device to authenticate the card 50. When the two parent device IDs match as a result of the matching, the parent device 70 transmits the address read from the card 50 to the child device 80. Hereinafter, the address transmitted from the parent device 70 to the child device 80 is referred to as a target address. Next, the child device 80 collates the target address received from the parent device 70 with the individual address and common address of the own device. Then, when the target address matches the individual address or common address of the own device, the slave device 80 causes the lock unit 83 to perform an operation according to the command.

As described above, the storage system 1 includes the card 50, the storage case 10, the master device 70, and the slave device 80 that controls the lock portion 83 of the storage case 10. The card 50 stores an address and a command corresponding to the operation of the lock unit 83. The parent device 70 acquires an address and a command from the card 50, and transmits the acquired address and command to the child device 80. Then, the child device 80 receives the address and the command transmitted by the parent device 70, and causes the lock unit 83 to perform the operation corresponding to the command based on the received address and the address set in the own device. ..

As a result, in the storage system 1, the card 50 stores the address and command of the child device 80, so that, for example, in the parent device 70, the process of identifying the address from the card ID is unnecessary. That is, in the storage system 1, the master 70 can lock and unlock the storage 10 corresponding to the card 50 without managing the address of the slave 80. That is, in the electric lock control system 100, the locking/unlocking of each storage case 10 can be controlled by connecting the required number of slave units 80 having the same configuration to the master unit 70. The number can be changed flexibly. Further, since the child device 80 only needs to have the same configuration, the manufacturer of the electric lock control system 100 can deliver the electric lock control system 100 inexpensively in a short delivery time.

Further, in the storage system 1, the parent device 70 authenticates the card 50 based on the parent device ID. Therefore, for example, even when a simple address that is the same as the address of another storage system is set in the child device 80, the storage system 1 can ensure security. Specifically, since each card 50 corresponds to the installation location of the storage system 1, a usable location is determined for each card 50. As described above, in the storage system 1, since the master device 70 performs the authentication process and the slave device 80 determines whether the lock portion 83 is locked or unlocked, it is possible to achieve both security and system flexibility.
The above is a description of the outline of the storage system 1.

(Structure of electric lock control system)
Next, the configuration of the electric lock control system 100 will be described with reference to FIG.
The electric lock control system 100 includes the above-described card 50, a master device 70, a plurality of slave devices 80, and a power supply unit 60 that supplies power to the master device 70 and the slave devices 80. In the present embodiment, as an example, the master device 70 and the plurality of slave devices 80 are serially connected and perform communication in accordance with the RS-485 standard. In the example shown in FIG. 2, the master device 70 or each slave device 80 is connected to two of the master device 70 or each slave device 80, respectively. For example, the child device 80-1 is connected to the parent device 70 and the child device 80-2. The master device 70 is connected to the slave devices 80-1 and 80-N, and all the master devices 70 or the slave devices 80 are connected in a ring type. Hereinafter, the device to which the master device 70 or each slave device 80 is connected may be referred to as an adjacent device.

The base device 70 transmits information to the two adjacent devices. Further, the child device 80 transmits the information received from one of the two adjacent devices to the other adjacent device. Further, the master device 70 discards the information received from the slave device 80. As a result, the information transmitted by the master device 70 is sequentially transmitted and shared by all the slave devices 80. In addition, the master device 70 and the slave device 80 are connected in a ring type, and the master device 70 transmits information to two adjacent devices. Therefore, the child device 80 has an opportunity to receive information twice, for example, via the clockwise route and the counterclockwise route. Therefore, even if one of the child devices 80 fails and cannot transmit/receive information, the information is transmitted via one of the two adjacent devices of the parent device 70, that is, a clockwise path or a counterclockwise direction. All of the child devices 80 can receive the information transmitted from the parent device 70 via the route.
The above is the description of the overall configuration of the electric lock control system 100.

(Card structure)
Next, the configuration of the card 50 will be described.
FIG. 3 is a block diagram showing the configuration of the card 50.
The card 50 includes a card communication unit 51, a card storage unit 52, and a card control unit 53. The card communication unit 51, the card storage unit 52, and the card control unit 53 may be implemented by an RFID tag, for example.

The card communication unit 51 communicates with the master device 70 and transmits and receives various information to and from the master device 70.
The card storage unit 52 includes, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). In addition, the card storage unit 52 may include an EEPROM (Electrically Erasable Programmable Read Only Memory), a flash memory, and the like. The card storage unit 52 stores, for example, an address, a master ID, and a command.

The card control unit 53 is a control IC that controls the operations of the card communication unit 51 and the card storage unit 52. The card control unit 53 reads, for example, an address, a master unit ID, and a command stored in the card storage unit 52 in response to a request from the master unit 70, and transmits them via the card communication unit 51. Further, for example, when the card control unit 53 receives a registration request for an address, a master unit ID, and a command from another device, the card storage unit 52 receives the received address, master unit ID, and command. Memorize.
The above is the description of the configuration of the card 50.

(Configuration of base unit)
Next, the configuration of the master device 70 will be described.
FIG. 4 is a block diagram showing the configuration of the master device 70.
The parent device 70 includes a parent device wireless communication unit 71, a parent device first wired communication unit 72, a parent device second wired communication unit 73, a parent device storage unit 74, and a parent device control unit 75.
The base unit wireless communication unit 71 includes, for example, an RFID tag reader or the like, and detects the card 50 presented by the user. The base unit wireless communication unit 71 communicates with the detected card 50 and acquires various information such as an address, a base unit ID, and a command from the card 50.

The base unit first wired communication unit 72 and the base unit second wired communication unit 73 include, for example, an RS-485 communication interface. The parent device first wired communication unit 72 and the parent device second wired communication unit 73 are respectively connected to one of two adjacent devices of the parent device 70. For example, in the case of the example shown in FIG. 2, the parent device first wired communication unit 72 connects to the child device 80-1, and the parent device second wired communication unit 73 connects to the child device 80-N.

The parent device storage unit 74 includes, for example, a ROM and a RAM. Further, the parent device storage unit 74 may include an EEPROM, a flash memory, or the like. The master storage unit 74 stores, for example, a master ID unique to the own device. The parent machine ID is configured to include, for example, a building ID in which the storage system 1 is installed, a floor ID, and a group ID. In the present embodiment, as an example, a case will be described in which a building ID is represented by 5 [Byte], a floor ID is represented by 2 [Byte], and a group ID is represented by 1 [Byte]. The parent device ID in this case is, for example, “AB001 13 A” or the like. The master ID may include arbitrary identification information related to the storage system 1, such as the ID of the administrator of the storage system 1.

The master unit control unit 75 includes an integrated circuit such as an ASIC (Application Specific Integrated Circuit), and the master unit wireless communication unit 71, the master unit first wired communication unit 72, the master unit second wired communication unit 73, and the master unit second wired communication unit 73. And the machine storage unit 74.
Specifically, when the parent device wireless communication unit 71 acquires the address, the parent device ID, and the command from the card 50, the parent device control unit 75 stores the obtained parent device ID of the card 50 and the parent device storage unit 74. It collates with the registered master ID. When the master device ID of the card 50 and the master device ID of the own device match, the master device control unit 75 includes a pulse signal (telegram) including the address (that is, the target address) acquired from the card 50 and the command. Is transmitted to the adjacent device of the own device via the parent device first wired communication unit 72 and the parent device second wired communication unit 73. Here, in the electric lock control system 100, since all the parent devices 70 and the child devices 80 are serially connected, the parent device first wired communication unit 72 and the parent device second wired communication unit 73 are adjacent devices. The pulse signal transmitted to the slave unit 80 is sequentially transmitted to all the slave units 80. In this pulse signal, for example, the address may be represented by 3 [Byte] and the command may be represented by 4 [Byte].
The above is the description of the configuration of the base device 70.

(Structure of child device)
Next, the configuration of the child device 80 will be described.
FIG. 5 is a block diagram showing the configuration of the child device 80.
The slave 80 includes a slave first communication unit 81, a slave second communication unit 82, a lock unit 83, an address setting unit 85, and a slave controller 86.
The handset first communication unit 81 and the handset second communication unit 82 include, for example, an RS-485 communication interface. The handset first communication unit 81 and the handset second communication unit 82 are respectively connected to one of the two adjacent devices of the own device. For example, in the case of the child device 80-1 illustrated in FIG. 2, the child device first communication unit 81 connects to the parent device 70 and the child device second communication unit 82 connects to the child device 80-2.

Here, the RS-485 communication corresponds to transmission of information from the child device 80 to the parent device 70, such as polling. However, in the present embodiment, as an example, transmission of information from the child device 80 to the parent device 70 is not performed. For example, when the child device 80 breaks down and the transmission to the parent device 70 is continuously performed, the processing of the parent device 70 is affected, and the abnormality may spread to other child devices 80. is there. On the other hand, by restricting the transmission of information from the child device 80 to the parent device 70, it is possible to prevent a failure of one child device 80 from affecting another child device 80.

The lock unit 83 is an electric lock including a drive unit such as a motor, and locks and unlocks the door in response to a command from the slave unit control unit 86.
The child device storage unit 84 includes, for example, a ROM and a RAM. Further, the child device storage unit 84 may include an EEPROM, a flash memory, or the like. The child device storage unit 84 stores various information such as a common address. The value of the common address may be settable by the address setting unit 85. In this case, the address setting unit 85 may be software.

The address setting unit 85 sets the individual address of its own device. The address setting unit 85 includes an arbitrary number of hardware modules such as a rotary switch, a DIP switch, and a jumper pin. The user can set an arbitrary address in the child device 80 by changing the settings of these modules.

Here, an example of setting an address will be described with reference to FIG. FIG. 6 shows an example of address setting using two decimal rotary switches “10SW1” and “10SW2”. In the example shown in FIG. 6, addresses “0” to “99” (“BOX address” in FIG. 6) are assigned to 100 storage boxes 10. The tens digit of each box address is indicated by the value of the rotary switch "10SW2", and the ones digit of each box address is indicated by the value of the rotary switch "10SW1". The address setting example shown in FIG. 6 is an example, and the address may be set using any number of hardware modules such as a rotary switch, a DIP switch, and a jumper pin. Further, address information may be stored in the child device storage unit 84. However, the electric lock control system 100 allows the individual address to be set using the hardware module, so that the individual address of the child device 80 can be easily set or changed without using special software or the like. be able to.
The above is the description of the address setting example.

The slave unit controller 86 includes an integrated circuit such as an ASIC, and controls the slave unit first communication unit 81, the slave unit second communication unit 82, and the lock unit 83.
Specifically, when the child device first communication unit 81 or the child device second communication unit 82 receives the pulse signal from the adjacent device, the child device control unit 86 determines that the target address indicated by the pulse signal is the individual address of the own device, Alternatively, it is determined whether or not it matches the common address. When the target address matches the individual address or the common address, the child device control unit 86 causes the lock unit 83 to perform an operation according to the command indicated by the pulse signal. When the slave unit first communication unit 81 receives the pulse signal, the slave unit control unit 86 causes the adjacent device of the own device to transmit the pulse signal via the slave unit second communication unit 82. When the slave unit second communication unit 82 receives the pulse signal, the slave unit control unit 86 causes the adjacent device of the own device to transmit the pulse signal via the slave unit first communication unit 81.

Here, the slave unit control unit 86 has two operation modes in the control of the lock unit 83, an immediate execution mode and a delayed execution mode.
The immediate execution mode is a mode in which when the target address matches the individual address or the common address, the lock unit 83 immediately executes the operation according to the command.
The delayed execution mode is a mode in which, when the target address matches the individual address or the common address, the lock unit 83 executes the operation according to the command after the elapse of a predetermined delay time. The delay time may be set arbitrarily. Here, as an example, the predetermined time is a value obtained by multiplying the address value by a predetermined unit time such as 0.2 seconds.

In the present embodiment, as an example, the child device control unit 86 operates the lock unit 83 in the immediate execution mode when the target address matches the individual address, and delays execution when the target address matches the common address. The lock portion 83 is operated in the mode. As a result, when the target address indicates an individual address, that is, when the command for the specific storage case 10 is executed, the child device control unit 86 operates the lock unit 83 without delay, so that the user can lock and unlock the door. Never make you wait. Further, when the target address indicates the common address, that is, when the command for all the storage cases 10 is executed, the lock part 83 of each storage case 10 is operated at a different time. Therefore, for example, even when all the storage cases 10 are locked and unlocked by one command, all the lock parts 83 do not operate at the same time, so that the power consumption does not suddenly increase. Therefore, the electric lock control system 100 can operate with less electric power. Further, for example, by setting the delay time in the delay execution mode to a value obtained by multiplying the address value by a predetermined unit time, it is possible to lock and unlock the lock unit 83 at a time corresponding to the address. That is, it is possible to easily confirm whether or not the address is set correctly from the locking/unlocking delay time.
The above is the description of the configuration of the child device 80.

(Operation of electric lock control system)
Next, the operation of the electric lock control system 100 will be described.
FIG. 7 is a sequence chart showing an example of the flow of processing by the electric lock control system 100.
(Step S100) The base device 70 determines whether or not the card 50 is detected. When the card 50 is detected (step S100; YES), the electric lock control system 100 advances the process to step S102. When the card 50 is not detected (step S100; NO), the electric lock control system 100 returns the process to step S100.
(Step S102) The parent device 70 acquires the parent device ID, the address, the command, and the update data from the card 50. After that, the electric lock control system 100 advances the process to step S104.

(Step S104) The parent device 70 determines whether or not the parent device ID acquired from the card 50 and the parent device ID of the own device match. When the parent device ID acquired from the card 50 and the parent device ID of the own device match (step S104; YES), the electric lock control system 100 advances the process to step S108. When the parent device ID acquired from the card 50 and the parent device ID of the own device do not match (step S104; NO), the electric lock control system 100 advances the process to step S122.

(Step S106) The parent device 70 compares the value of the update data acquired from the card 50 with the value of the update data stored in its own device. When the value of the update data acquired from the card 50 is equal to or larger than the value of the update data stored in the device itself (step S106; YES), the electric lock control system 100 advances the process to step S108. When the value of the update data acquired from the card 50 is smaller than the value of the update data stored in the device itself (step S106; NO), the electric lock control system 100 advances the process to step S122.

(Step S108) The master device 70 stores the update data acquired from the card 50 in association with the address, and stores the address (that is, the target address) acquired from the card 50 and the command, which is an adjacent device of its own device. It transmits to the two child devices 80. After that, the electric lock control system 100 advances the process to step S110.
(Step S110) The child device 80 receives the target address and the command from the adjacent device of the own device. After that, the electric lock control system 100 advances the process to step S112.

(Step S112) The child device 80 determines whether or not the target address matches the common address. When the target address matches the common address (step S114; YES), the electric lock control system 100 advances the process to step S114. When the target address does not match the common address (step S114; NO), the electric lock control system 100 advances the process to step S116.
(Step S114) The subunit|mobile_unit 80 clocks and suspends a process until a predetermined delay time passes. After that, the electric lock control system 100 advances the process to step S118.

(Step S116) The child device 80 determines whether or not the target address matches the individual address. When the target address matches the individual address (step S116; YES), the electric lock control system 100 advances the process to step S118. When the target address does not match the individual address (step S116; NO), the electric lock control system 100 advances the process to step S120.

(Step S118) The child device 80 controls the lock part 83 according to the command. After that, the electric lock control system 100 advances the process to step S120.
(Step S120) The child device 80 transmits the target address and the command to a neighboring device that is different from the neighboring device that has transmitted the target address and the command to the own device among the two neighboring devices of the own device. After that, the electric lock control system 100 advances the process to step S122.

(Step S122) The base device 70 discards the target address and the command. At this time, the target address and command to be discarded are the target address and command acquired from the card 50 that does not match the parent device ID of the own device or all the slave devices 80 connected in the ring type. It is the target address and command that has returned. After that, the electric lock control system 100 returns the process to step S100.

(Summary of this embodiment)
As described above, the electric lock control system 100 according to the present embodiment includes the card 50, the master unit 70, and the slave unit 80 that controls the electric lock (for example, the lock unit 83). In the system, the card 50 is a card storage unit that stores first identification information (for example, a target address) of a plurality of child device identification information corresponding to a child device and a command corresponding to an operation of an electric lock. The base unit 70 includes the base unit wireless communication unit 71 that acquires the first identification information and the command from the card 50, and the first unit identification information and the command that the base unit wireless communication unit 71 acquires. The base unit first wired communication unit 72 and the base unit second wired communication unit 73 for transmitting to the second unit 80, the handset unit 80, the second identification information (for example, individual address, common address) of the plurality of identification information. ), a slave unit first communication unit 81 and a slave unit second communication unit 82 that receive the first identification information and the command transmitted by the master unit 70, and a slave unit first communication unit 81. And a slave unit controller 86 that causes the electric lock to perform an operation corresponding to the command, based on the first identification information received by the slave second communication unit 82 and the second identification information set by the address setting unit 85. , Is provided.

As a result, the electric lock control system 100 can cause the electric lock to perform an operation according to a command by storing the identification information corresponding to the slave device 80 in the card 50. In other words, the electric lock control system 100 may control the electric lock of the storage box 10 without managing identification information such as individual address of the slave unit 80 to the base unit 70. Therefore, the electric lock control system 100 can flexibly change the number of electric locks.
Specifically, in the electric lock control system 100, the number of storages 10, that is, the number of locks 83 is, for example, 10 at one time and 90 at another time. Even if the number differs depending on the number, it is possible to deal flexibly. In addition, since the parent device 70, the child device 80, and the lock unit 83 may have exactly the same function and performance, the system supplier can provide the system at a low cost with a short delivery time, and perform maintenance management. It's easy.

Further, the electric lock control system 100 includes a plurality of child devices 80, and the child device 80 communicates with the parent device 70 and two adjacent devices different from its own device among the plurality of child devices 80, and the child devices 80 communicate with each other. The device first communication unit 81 and the child device second communication unit 82 transmit the first identification information and the command received from one of the two adjacent devices to the other.
Thereby, the electric lock control system 100 can transmit the first identification information and the command to all the slaves 80 even if the number of the slaves 80 as a whole is not specified. Therefore, the electric lock control system 100 can flexibly change the number of electric locks.

Further, the parent device first wired communication unit 72 and the parent device second wired communication unit 73 transmit the first identification information and the command acquired by the parent device wireless communication unit 71 to the two child devices 80.
As a result, the master device 70 can transmit the command to all the slave devices 80 via the two routes. Therefore, for example, even when one of the slaves 80 fails and information cannot be transmitted/received, the command can be transmitted to all the other slaves 80. Therefore, the electric lock control system 100 can be a robust system that is resistant to failure, and maintenance can be facilitated. Further, by adopting a one-output serial communication base such as RS-485 for the base device 70, the base device 70 can be significantly downsized as compared with the case where a multi-output base is adopted.

Further, the child device first communication unit 81 and the child device second communication unit 82 do not transmit information to the parent device 70.
As a result, the electric lock control system 100 can prevent the failure of a certain slave device 80 from spreading to the master device 70 and impairing the operation of the entire electric lock control system 100. Therefore, the electric lock control system 100 can be a robust system that is resistant to failure, and maintenance can be facilitated.

Also, the address setting unit 85 uses, as the second identification information, third identification information (for example, an individual address) different from each other in the plurality of slaves 80 and fourth identification information that is common to the plurality of slaves 80 (for example, the common identification). And/or address).
Thereby, the electric lock control system 100 can lock/unlock a specific electric lock or lock/unlock a plurality of electric locks all at once in accordance with the card 50 presented by the user. Therefore, for example, when cleaning each storage case 10, by presenting the card 50 that stores the common address, the electric locks can be locked and unlocked all at once, so that maintenance and management can be easily performed.

Further, the child device control unit 86 includes the first identification information (for example, the target address) received by the child device first communication unit 81 or the child device second communication unit 82 and the fourth identification information set by the address setting unit 85. When they match (for example, a common address), a plurality of slave units 80 are provided with delays of different predetermined times to start the operation corresponding to the command to the electric lock.

As a result, the electric lock control system 100 can change the locking/unlocking timing of each locking unit 83 even when locking/unlocking the locking units 83 of the plurality of child devices 80 all at once. Thereby, the electric lock control system 100 can be operated with less electric power.

The address setting unit 85 also includes a hardware module that sets the second identification information.
Thus, the user of the electric lock control system 100 can easily set the address of the child device 80.
