(1) Outline The outline of the electric lock system including the electric lock control system according to the present embodiment will be described below. As shown in FIG. 1, the electric lock system 10 according to the present embodiment includes an electric lock control system 1 and a key device 2. Further, the electric lock system 10 further includes an electric lock 3 controlled by the electric lock control system 1.

The electric lock control system 1 according to the present embodiment is a system for controlling the electric lock 3. The electric lock 3 locks or unlocks the opening / closing member 5 (see FIGS. 2 and 3). The opening / closing member 5 opens / closes the opening 40 of the building 4. The opening / closing member 5 is a door or window that separates the inside (inside 41) and the outside (outside 42) of the building 4, and is, for example, a door (swing door or sliding door) such as an entrance or a doorway, or a sweep-out window. is there. In the present embodiment, the opening / closing member 5 is a front door. The electric lock control system 1 and the electric lock 3 are installed on the opening / closing member 5. The electric lock control system 1 is configured to be able to communicate with the key device 2. The electric lock control system 1 is configured to electrically switch between a locked state in which the opening / closing member 5 is locked and an unlocking state in which the opening / closing member 5 is unlocked by communicating with the key device 2.

The key device 2 has a communication function with the electric lock control system 1. In the present embodiment, the communication method between the electric lock control system 1 and the key device 2 is wireless communication using radio waves as a medium. The key device 2 is, for example, a battery-powered mobile terminal device, and in the present embodiment, the power source of the electric lock control system 1 is also a battery. In the present embodiment, the case where the building 4 is a detached house will be described as an example. Therefore, the user 6 is a resident of the building 4 and related persons who own the key device 2. When there are a plurality of users 6, the plurality of users 6 may each own the key device 2, and in that case, the electric lock system 10 includes the plurality of key devices 2.

The electric lock 3 electrically locks or unlocks the opening / closing member 5 by a locking signal or an unlocking signal output from the lock side control unit 11 (described later) of the electric lock control system 1. That is, the electric lock 3 is switched to a locked state in which the opening / closing member 5 is locked or an unlocking state in which the opening / closing member 5 is unlocked by a locking signal or an unlocking signal from the lock side control unit 11.

The electric lock control system 1 and the electric lock system 10 according to the present embodiment are configured as follows so as to improve the security performance.

As shown in FIG. 1, the electric lock control system 1 according to the present embodiment includes a lock-side communication unit 13 and a lock-side control unit 11.

The lock-side communication unit 13 wirelessly communicates with the key device 2.

The lock-side control unit 11 controls the electric lock 3 that locks or unlocks the opening / closing member 5 based on the information received from the key device 2 by the lock-side communication unit 13. The lock-side control unit 11 detects whether or not the key device 2 exists in a predetermined communication range A1 (see FIGS. 2 and 3) based on the communication state between the lock-side communication unit 13 and the key device 2. To do. The predetermined communication range A1 is, for example, a range in which the strength of the signal received from the key device 2 by the lock-side communication unit 13 is equal to or higher than a predetermined first threshold value. In the present embodiment, the "first threshold value" is set to a value corresponding to the strength of the received signal from the key device 2 located at a position several meters away from the installation location of the electric lock control system 1.

The lock side control unit 11 detects the existence of the key device 2 in the communication range A1 and performs the first process when the determination condition is satisfied in the state where the existence of the key device 2 is detected in the communication range A1. The "first treatment" is a treatment for locking or unlocking the electric lock 3. The lock-side control unit 11 performs a predetermined second process different from the first process when the state in which the determination condition is not satisfied continues for a predetermined standby time T1 or more in the state where the key device 2 exists in the communication range A1. ..

Here, the "standby time T1" is, for example, about 1 minute to 5 minutes, and can be appropriately changed according to the setting of the communication range A1 and the usage environment.

The "judgment condition" is a condition for locking or unlocking the electric lock 3. The determination condition includes, for example, a condition that the strength of the received signal from the key device 2 is equal to or higher than a predetermined second threshold value (threshold value). In the present embodiment, the lock side operation unit 15 of the electric lock control system 1 ( It further includes the condition that (described later) is operated. Here, the key device 2 is, for example, a key device that is permitted to lock or unlock the electric lock 3.

The "second threshold value" is set to a value larger than the first threshold value. An authentication area A2 narrower than the communication range A1 is set in the vicinity of the opening 40 in the outside of the house 42. The authentication area A2 has a distance of about 1 m from the opening / closing member 5, and the strength of the signal received by the lock-side communication unit 13 from the key device 2 existing in the authentication area A2 is equal to or higher than the second threshold value. The value of the second threshold value is set. Therefore, the above-mentioned determination condition includes the condition that the key device 2 exists in the authentication area A2, and further includes the condition that the lock side operation unit 15 is operated in the present embodiment.

The "second treatment" is a treatment different from the first treatment for locking or unlocking the electric lock 3. The second process is, for example, a process of changing the determination condition. As described above, when the determination condition is not satisfied while the key device 2 is present in the communication range A1 and the predetermined standby time T1 or more continues, the first process of locking or unlocking the electric lock 3 is performed. Since there is no such thing, security performance can be improved.

In the present embodiment, the second process is a process of changing the determination condition so that the determination condition is less likely to be satisfied. For example, the threshold value of the received signal strength (second threshold value) is set before the determination condition is changed. This is the process of changing to a larger value. Here, when the threshold value (second threshold value) of the received signal strength is changed to a value larger than that before the determination condition is changed, the authentication area A2 is changed to a narrow range A22 as compared with the range A21 before the change. (See FIGS. 2 and 3). In the following, the authentication area A2 before the second process (before the change) may be referred to as the authentication area A21, and the authentication area A2 after the second process (after the change) may be referred to as the authentication area A22. For example, when the user 6 exists outside the authentication area A22 in the authentication area A21, the determination condition is changed when the determination condition is changed by the second process and the authentication area A2 is changed from the authentication area A21 to the authentication area A22. It will be unsuccessful. Therefore, in this state, the electric lock 3 is not unlocked, and there is an advantage that the security performance can be improved.

The lock-side communication unit 13 has, for example, an antenna and a communication circuit, and performs wireless communication using radio waves as a medium. The lock-side communication unit 13 is configured to perform short-range wireless communication conforming to, for example, the BLE [Bluetooth (registered trademark) Low Energy] standard. Here, "BLE" is a name for a low power consumption specification (version 4.0 or higher) in the specification of Bluetooth (registered trademark) which is a wireless PAN (Personal Area Network) technology. The lock-side communication unit 13 intermittently (for example, at 1-second intervals) transmits an advertisement signal (beacon signal) in accordance with a command from the lock-side control unit 11. Further, the lock-side communication unit 13 receives a response signal transmitted from the key-side communication unit 22 (described later) in response to the advertisement signal. That is, the lock-side communication unit 13 has a signal transmission function and a signal reception function, and is configured to perform bidirectional communication with the key-side communication unit 22. Further, the lock-side communication unit 13 has a function of measuring the received signal strength (RSSI: Received Signal Strength Indicator) of the received wireless signal (radio wave signal) Sig1. When the lock-side communication unit 13 receives the wireless signal Sigma1 from the key device 2, it locks information such as key information included in the wireless signal Sigma1 and the received signal strength (measured value) of the wireless signal Sigma1 (received signal). Output to the side control unit 11.

The notification unit 14 has, for example, a display unit composed of an LED (Light Emitting Diode) or the like, and a buzzer. The notification unit 14 has a function of notifying the user 6 whether or not the opening / closing member 5 is locked. The notification unit 14 causes, for example, display the operating state of the electric lock 3 on the display unit. Specifically, the notification unit 14 turns on or blinks the LED when the opening / closing member 5 is locked or unlocked by the electric lock 3. Further, the notification unit 14 sounds a buzzer when the opening / closing member 5 is not locked by the electric lock 3. As a result, the user 6 can know whether or not the opening / closing member 5 is locked according to the notification content of the notification unit 14. The notification unit 14 is not an essential configuration for the electric lock control system 10, and can be omitted as appropriate.

The lock-side operation unit 15 has a function of receiving an operation input by the user 6 (that is, a person). The lock-side operation unit 15 includes, for example, a push button switch provided on the case 17 so as to be exposed to the outside of the building 4 (outside the house 42). The lock side operation unit 15 may be provided on, for example, a door handle (handle) provided on the opening / closing member 5 (entrance door), or is a touch sensor or the like that detects an operation in which the user 6 touches the door handle. You may. When the lock-side operation unit 15 receives the operation input by the user 6, the lock-side operation unit 15 outputs an operation signal corresponding to the operation input to the lock-side control unit 11.

The lock-side storage unit 16 includes an electrically rewritable non-volatile memory such as an EEPROM (Electrically Erasable and Programmable Read-Only Memory). The lock-side storage unit 16 stores the key information of one or more key devices 2 authorized to control the electric lock 3 as authentication information. Different key information is assigned to the plurality of key devices 2. Therefore, the lock-side storage unit 16 stores the identification information of the key device 2 and the key information given to the key device 2 in association with each other. Further, the lock-side storage unit 16 also stores in advance the determination conditions before the second processing is performed, the determination conditions after the second processing is performed, the release conditions for canceling the second processing, and the like. ..

The lock side control unit 11 controls the electric lock 3 that locks or unlocks the opening / closing member 5. The lock-side control unit 11 is composed of, for example, a microcomputer having a processor and a memory. That is, the lock side control unit 11 is realized in a computer system having a processor and a memory. When the processor executes a program recorded in the memory or the lock side storage unit 16, for example, various functions of the lock side control unit 11 (for example, functions of the authentication unit 111, the determination unit 112, etc.) are realized by the computer system. Will be done. The program may be pre-recorded in the memory of the microcomputer or the lock side storage unit 16, or may be recorded and provided through a telecommunication line such as the Internet or a non-temporary recording medium such as a memory card. Good.

The authentication unit 111 collates the key information received from the key device 2 by the lock-side communication unit 13 with the authentication information stored in the lock-side storage unit 16, so that the key device 2 that has transmitted the key information is an electric lock. It authenticates whether or not the key device 2 is authorized to control 3.

The determination unit 112 determines whether or not to perform the first process and the second process based on the information received from the key device 2 by the lock side communication unit 13. When the lock-side communication unit 13 receives the wireless signal Sigma 1 from the key device 2, the information contained in the wireless signal Sigma 1 received from the key device 2 and the strength (measured value) of the wireless signal Sigma 1 are transmitted to the lock-side control unit 11. Output. The determination unit 112 compares the height of the received signal strength input from the lock side communication unit 13 with the first threshold value. If the received signal strength is equal to or higher than the first threshold value, the determination unit 112 determines that the key device 2 exists in the communication range A1, and causes the authentication unit 111 to authenticate the key device 2.

When the determination unit 112 determines that the determination condition is satisfied while detecting the existence of the key device 2 in the communication range A1, the determination unit 112 executes the first process. That is, the determination unit 112 performs the first process when the determination condition is satisfied between the predetermined timing and the elapse of the predetermined standby time in the state where the presence of the key device 2 is detected in the communication range A1. As described above, when the key device 2 enters the communication range A1, the authentication unit 111 performs a process of collating the key information of the key device 2 with the authentication information. The "predetermined timing" is the authentication unit 111. This is the timing when the key device 2 in which the key information is successfully authenticated by the user enters the authentication area A2. That is, it is the timing when the determination unit 112 determines that the strength of the received signal from the key device 2 in which the authentication unit 111 has successfully authenticated the key information is equal to or higher than the second threshold value. If the key device 2 enters the authentication area A2 before the authentication of the key information by the authentication unit 111 is completed, the timing at which the authentication unit 111 succeeds in authenticating the key information of the key device 2 that has entered the authentication area A2. Is the "predetermined timing". In the present embodiment, the "determination condition" is a condition that the received signal strength (measured value) from the key device 2 is equal to or higher than the second threshold value and the lock side operation unit 15 is operated by a person. Therefore, if the lock side operation unit 15 is operated while the key device 2 is present in the authentication area A2 from the predetermined timing until the standby time T1 elapses, the determination unit 112 determines that the determination condition is satisfied. Then, the first process is executed.

On the other hand, if the lock side operation unit 15 is not operated even after the standby time T1 elapses from the predetermined timing, the determination unit 112 determines that the state in which the determination condition is not satisfied continues for the standby time or longer, and the second Perform processing. The second process is a process of changing the determination condition, for example, a process of changing the value of the second threshold value to a value larger than that before the determination condition is changed. When the determination unit 112 executes the second process, the authentication area A2 is changed to the authentication area A22 which is narrower than the authentication area A21 before the change.

When the dead bolt is moved to the unlocked position, the entire dead bolt is out of the bolt hole, and in this state, the opening / closing member 5 can be opened / closed. That is, the opening / closing member 5 is unlocked.

(3) Operation First, the first process performed by the electric lock control system 1 will be described with reference to FIG.

In the electric lock control system 1, the lock-side communication unit 13 periodically (for example, every second) transmits an advertisement signal (S1).

It is assumed that the user 6 carrying the key device 2 approaches the opening 40 of the building 4 in order to enter the house 41 from the outside 42. When the user 6 carrying the key device 2 approaches the opening 40 of the building 4 outside the house 42 and the key device 2 receives the advertisement signal from the lock side communication unit 13, the key device 2 locks the response signal to the advertisement signal. It is transmitted to the side communication unit 13 (S2).

The lock-side control unit 11 compares the magnitude of the received signal strength (measured value) of the lock-side communication unit 13 with the first threshold value, and if the received signal strength is equal to or higher than the first threshold value, the key device 2 has a communication range. It is determined (detected) that it exists in A1 (S3).

When the lock-side control unit 11 detects the key device 2 existing in the communication range A1, the lock-side control unit 11 periodically (for example, 0.) between the lock-side communication unit 13 and the key device 2 in order to monitor the state of the key device 2. Communicate every second) (S4: monitoring process).

When the lock side control unit 11 starts communication with the key device 2, the lock side control unit 11 performs an authentication process of the key device 2 (S5). The lock side control unit 11 requests the key device 2 to transmit the key information from the lock side communication unit 13, and when the lock side communication unit 13 receives the key information transmitted from the key device 2, the lock side storage unit stores the key information on the lock side. It is collated with the authentication information stored in the unit 16. If the key information matches the authentication information (that is, when the key information authentication is successful), the lock side control unit 11 determines that the key device 2 is authorized to control the electric lock 3, and the key information is authenticated. If it does not match the information, it is determined that the key device 2 does not allow the control of the electric lock 3.

When the key information authentication is successful, the lock side control unit 11 causes the lock side communication unit 13 and the key device 2 to perform periodic communication, and the strength of the received signal from the key device 2 is equal to or higher than the second threshold value. Then, it is determined that the key device 2 exists in the authentication area A2 (S6).

Then, when the user 6 operates the lock-side operation unit 15 between the timing when the lock-side control unit 11 determines that the key device 2 exists in the authentication area A2 and the elapse of the predetermined standby time T1, the lock-side operation An operation signal is output from the unit 15 to the lock side control unit 11 (S7). If the operation signal is input from the lock side operation unit 15 before the standby time T1 elapses, the lock side control unit 11 determines that the determination condition is satisfied (S8), and outputs an unlock signal to the electric lock 3. (S9). The electric lock 3 unlocks the opening / closing member 5 when an unlocking signal is input from the lock side control unit 11 (S10). That is, the lock side control unit 11 performs the first process of unlocking the opening / closing member 5. As a result, the user 6 carrying the key device 2 can open the opening / closing member 5 and enter the house 41. The lock-side control unit 11 may output a lock signal to the electric lock 3 to lock the electric lock 3 after a certain period of time has elapsed after unlocking the electric lock 3.

Next, the second process performed by the electric lock control system 1 will be described with reference to FIG.

In the electric lock control system 1, the lock-side communication unit 13 periodically transmits an advertisement signal (S11).

It is assumed that the user 6 carrying the key device 2 approaches the opening 40 of the building 4 in order to enter the house 41 from the outside 42. When the user 6 carrying the key device 2 approaches the opening 40 of the building 4 outside the house 42 and the key device 2 receives the advertisement signal from the lock side communication unit 13, the key device 2 locks the response signal to the advertisement signal. It is transmitted to the side communication unit 13 (S12).

The lock-side control unit 11 compares the magnitude of the received signal strength of the lock-side communication unit 13 with the first threshold value, and if the received signal strength is equal to or higher than the first threshold value, the key device 2 exists within the communication range A1. Then, it is determined (detected) (S13).

When the lock side control unit 11 detects the key device 2 existing in the communication range A1, the lock side control unit 11 causes the lock side communication unit 13 and the key device 2 to periodically communicate with each other in order to monitor the state of the key device 2. (S14: Monitoring process).

When the lock side control unit 11 starts communication with the key device 2, the lock side control unit 11 performs an authentication process of the key device 2 (S15). The lock side control unit 11 requests the key device 2 to transmit the key information from the lock side communication unit 13, and when the lock side communication unit 13 receives the key information transmitted from the key device 2, the lock side storage unit stores the key information on the lock side. It is collated with the authentication information stored in the unit 16.

When the key information authentication is successful, the lock side control unit 11 causes the lock side communication unit 13 and the key device 2 to perform periodic communication, and the strength of the received signal from the key device 2 is equal to or higher than the second threshold value. Then, it is determined that the key device 2 exists in the authentication area A2 (A21) (S16).

Here, when the lock side operation unit 15 is not operated from the timing when the key device 2 is determined to exist in the authentication area A21 until the standby time T1 elapses, that is, the state in which the determination condition is not satisfied is the standby time T1. After the above lapse, the lock side control unit 11 performs the second process (S17). Here, the second process is a process of changing the determination condition, and by setting the second threshold value to a value larger than that before the change, the authentication area A2 is narrower than the authentication area A21 before the change. Change to. When the lock side control unit 11 performs the second process, the lock side control unit 11 determines whether to lock or unlock based on the changed determination condition.

For example, when the user 6 carrying the key device 2 is stopped outside the authentication area A22 in the authentication area A21, the user 6 is located outside the changed authentication area A22. Therefore, in this state, a third party Even if the lock side operation unit 15 is operated by, the determination condition is not satisfied. Therefore, the possibility that the electric lock 3 is unlocked by a third party who is not permitted to unlock the electric lock 3 is reduced, and the security performance can be improved.

After that, when the user 6 carrying the key device 2 moves to the authentication area A22, the lock side control unit 11 is permitted to lock or unlock the electric lock 3 based on the strength of the received signal from the key device 2. It is determined that the key device 2 exists in the authentication area A22 (S18). When the user 6 operates the lock-side operation unit 15 in this state (S19), an operation signal is output from the lock-side operation unit 15 to the lock-side control unit 11. When the operation signal is input from the lock side operation unit 15, the lock side control unit 11 determines that the determination condition is satisfied (S20), and outputs an unlock signal to the electric lock 3 (S21). The electric lock 3 unlocks the opening / closing member 5 when an unlocking signal is input from the lock side control unit 11 (S22). That is, the lock side control unit 11 performs the first process of unlocking the opening / closing member 5. As a result, the user 6 carrying the key device 2 can open the opening / closing member 5 and enter the house 41. The lock-side control unit 11 may output a lock signal to the electric lock 3 to lock the electric lock 3 after a certain period of time has elapsed after unlocking the electric lock 3.

In this way, the electric lock control system 1 determines whether or not to perform the first process according to the changed determination condition even after the second process is performed to change the determination condition. Therefore, even after the determination condition is changed by the second process, the electric lock 3 can be unlocked or controlled by using the key device 2, and the security performance is improved while maintaining the usability of the electric lock control system 1. it can.

Further, the lock side control unit 11 determines that the predetermined unlocking condition is satisfied when the authentication process based on the key information of the key device 2 is successful and the unlocking of the electric lock 3 is completed after the second process is performed. Then, the second process is canceled and the state before the second process is returned to the state (S23). That is, the lock side control unit 11 returns the determination condition to the determination condition before the change by the second process, and returns the second threshold value to the value before the change. As a result, the authentication area A2 changes from the changed authentication area A22 to the authentication area A21, and the state in which the authentication area A2 is restricted does not continue, so that the usability of the electric lock control system 1 is improved.

(4) Modifications The above embodiment is only one of the various embodiments of the present disclosure. The above-described embodiment can be changed in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Further, the same function as that of the electric lock control system 1 may be realized by a control method of the electric lock control system 1, a computer program, a non-temporary recording medium on which the computer program is recorded, or the like.

The control method according to one aspect includes a first process and a second process. Further, the program according to one aspect is a program for causing a computer system to execute a first process and a second process. In the first process, when the determination condition is satisfied while the presence of the key device 2 is detected in the predetermined communication range A1 based on the communication state with the key device 2, the electric lock 3 is locked or unlocked. This is a process (step S8 in FIG. 4). The second process is a predetermined process different from the first process, which is performed when the determination condition is not satisfied between the timing when the presence of the key device 2 is detected in the communication range A1 and the elapse of the waiting time T1 (the second process). Step S15 in FIG. 5).

Hereinafter, modifications of the above-described embodiment will be listed. The modifications described below can be applied in combination as appropriate.

(4.1) Modification 1
In the above-described embodiment, the case where the received signal strength used in the determination process of the determination unit 112 is the reception signal strength of the wireless signal Sigma 1 from the key device 2 has been described as an example, but the wireless signal from the electric lock control system 1 has been described. It may be the received signal strength of. In this case, the reception signal strength of the radio signal from the electric lock control system 1 is measured by the key device 2, and the measurement result is transmitted from the key device 2 to the electric lock control system 1. Then, the determination unit 112 of the electric lock control system 1 performs the determination process based on the reception signal strength (measured value) of the reception signal received by the key device 2.

Further, the key device 2 may be provided with a determination unit. In this case, the received signal strength used in the determination process of the determination unit may be the received signal strength of the radio signal Sigma 1 from the key device 2 to the electric lock control system 1, or the received signal strength from the electric lock control system 1 to the key device 2. It may be the received signal strength of the radio signal to. In the case of the wireless signal Sigma 1 from the key device 2 to the electric lock control system 1, the received signal strength of the wireless signal Sigma 1 is measured by the electric lock control system 1, and the measurement result is transferred from the electric lock control system 1 to the key device 2. Send. Further, in the case of a wireless signal from the electric lock control system 1 to the key device 2, the received signal strength of the wireless signal is measured by the key device 2. Then, the determination unit of the key device 2 may perform the determination process based on the acquired received signal strength.

(4.2) Modification 2
The second process was a process of changing the second threshold value, which is the threshold value of the received signal strength. For example, by changing the sensitivity of the lock side communication unit 13 or the key side communication unit 22, the authentication area A2 It may be a process of changing. When the lock side control unit 11 changes the sensitivity of the key side communication unit 22 of the key device 2, the lock side communication unit 13 transmits a control signal for reducing the sensitivity to the key device 2, and the key device 2 receives the reception sensitivity. Should be changed.

Further, the second process may be a process of changing the detection condition for detecting whether or not the key device 2 exists. For example, in the second process, the range for detecting whether or not the key device 2 exists (communication range A1) is changed by increasing the value of the first threshold value or lowering the transmission output of the advertisement signal. The process may be narrower than before.

Further, the second process may be a process of changing the time interval in which the lock-side communication unit 13 communicates with the key device 2 existing in the communication range A1. For example, in the second process, the communication time interval may be changed to a longer time interval (for example, 1 second interval) than before the change, and the number of communications (frequency) per unit time is reduced. In this way, since the number of communications between the lock-side communication unit 13 and the key device 2 is reduced, the power consumption of the electric lock control system 1 and the key device 2 can be reduced.

(4.3) Modification 3
The release condition for releasing the second process is that the authentication process based on the key information of the key device 2 is successful and the unlocking of the electric lock 3 is completed, but the authentication process based on the key information of the key device 2 is performed. It may be a condition that the locking of the electric lock 3 is completed successfully.

Here, when the electric lock control system 1 includes a plurality of key devices 2, the release condition for releasing the second process is to lock the electric lock 3 by using the key device 2 that caused the second process to be performed. It may be a condition that unlocking is completed. In this case, since the second process cannot be canceled by the other key device 2, the security performance can be improved.

Further, the release condition for releasing the second process may be a condition that the locking or unlocking of the electric lock 3 is completed by any of the plurality of key devices 2. In this case, since the second process can be canceled by any key device 2, usability is improved.

Further, the release condition for releasing the second process may be a condition that the communication state between the key device 2 and the lock side communication unit 13 changes. For example, the release condition may be a condition that the received signal strength received from the key device 2 by the lock-side communication unit 13 is lower than the first threshold value, that is, a condition that the key device 2 goes out of the communication range A1.

Further, the release condition may be a condition that the lock-side communication unit 13 cannot communicate with the key device 2, for example, a condition that the key device 2 has moved to a distance where the advertisement signal from the lock-side communication unit 13 cannot be received.

Further, the second process may be released for all the key devices 2 depending on the release conditions, or the second process may be released only for the specific key device 2. For example, when the unlocking condition is that the locking or unlocking of the electric lock 3 is completed, the lock side control unit 11 releases the second process for all the key devices 2 in the authentication area A2. If the release condition is that the key device 2 goes out of the communication range A1, the lock side control unit 11 releases the second process only for the key device 2 that goes out of the communication range A1. In this case, when another key device 2 exists in the communication area A1, the lock side control unit 11 does not release the second process for the other key device 2 in the communication area A1.

(Summary)
As is clear from the above-described embodiment, the electric lock control system (1) of the first aspect has a lock-side communication unit (13) and a lock-side communication unit (13) that wirelessly communicate with the key device (2). Includes a lock-side control unit (11) that controls the electric lock (3) based on information received from the key device (2).
The electric lock (3) locks or unlocks the opening / closing member (5) that opens / closes the opening (40) of the building (4). The lock-side control unit (11) detects the presence of the key device (2) in a predetermined communication range (A1) based on the communication state between the lock-side communication unit (13) and the key device (2). When the determination condition is satisfied in the above, the first process of locking or unlocking the electric lock (3) is performed.
