The control device 300 is managed by the management server 80. The management server 80 may provide a service of an application (may be described as an application) for managing the control device 300. The control device 300 unlocks according to, for example, an unlock signal transmitted by the management server 80. Further, the control device 300 locks according to, for example, a lock signal transmitted by the management server 80.

The barrier device 100 relays communication between the management server 80 and the control device 300. The barrier device 100 communicates with the management server 80 via the network 70.

May be good. Here, a case where the mobile communication network complies with the LTE communication method will be described as an example. The barrier device 100 may access the mobile communication network via a radio base station. The network 70 may include the Internet.

The barrier device 100 has a gateway 102 and a hub 104. The gateway 102 transmits a signal to the control device 300 via the wireless relay device 200 according to the instruction of the management server 80. The hub 104 connects a plurality of wireless relay devices 200. The hub 104 may be an example of a connection contact. The hub 104 may be arranged outside the barrier device 100 without the barrier device 100 having the hub 104.

In this case, depending on the positional relationship of the plurality of wireless relay devices 200, wireless interference may occur, resulting in an error in setting the password for at least one of the plurality of wireless relay devices 200. For example, when a plurality of control devices 300 are installed on the doors of each room of a hotel, radio interference occurs between signals to the plurality of control devices 300 installed in adjacent rooms, and the control device 300 May not be able to receive the signal normally. Even if the barrier device 100 retransmits the set signal in response to the occurrence of an error, wireless interference may occur again and an error may occur again, which hinders the normal operation of the control device 300.

The barrier device 100 according to the present embodiment has a function for suppressing the occurrence of such radio interference. The barrier device 100 controls each of the plurality of wireless relay devices 200 so that the timing of wirelessly transmitting a signal to each of the plurality of control devices 300 is different.

For example, when the barrier device 100 sets different delay times for each of the plurality of wireless relay devices 200 and causes the plurality of wireless relay devices 200 to transmit the signal received from the management server 80, the delay time of each is set. The signal is transmitted with a delay of 1 minute. As a result, the timing of wireless transmission of signals by the plurality of wireless relay devices 200 can be made different, and the possibility of wireless interference can be reduced.

Here, the description will be continued on the assumption that the set signal has not reached two or more of the control devices 300 among the plurality of control devices 300 due to wireless interference.

It is said that a control error has occurred in response to the fact that the wireless relay device 200 has not received a response from the control device 300 between the time when the set signal is transmitted in S106 and the time when a predetermined time elapses. to decide. In S108, the wireless relay device 200 that determines that the control error has occurred transmits the control error to the barrier device 100.

In S112, the barrier device 100 waits for each of the plurality of wireless relay devices 200 for each delay time, and then retransmits the set signal. As a result, the transmission timings of the two or more wireless relay devices 200 in which the wireless interference has occurred can be made different from each other, and it is possible to prevent the wireless interference from occurring again.

In S114, each of the plurality of wireless relay devices 200 wirelessly transmits a setting signal to the corresponding control device 300.

In S120, the barrier device 100 transmits a received response indicating the completion of the setting to the management server 80.

FIG. 4 is an explanatory diagram for explaining the steady-state monitoring process by the barrier device 100. The barrier device 100 according to the present embodiment may execute a steady monitoring process of constantly monitoring each of the state of the barrier device 100 and the state of the control device 300 and reporting to the management server 80.

The barrier device 100 transmits, for example, state information indicating the state of the barrier device 100 to the management server 80 at predetermined first time intervals. The first time may be arbitrarily set, for example, 10 minutes, or may be changeable.

Further, the barrier device 100 manages state information indicating the state of the control device 300 when the communication with the control device 300 via the wireless relay device 200 is not continuously performed for a predetermined second time. Send to server 80. The second time may be longer than the first time. For example, a time such as 3 hours is set as the second time. The second time may be arbitrarily set and may be changeable.

The barrier device 100 is, for example, via a radio base station, a communication path 152 and a communication path 154 established with an IoT-PF (Internet of Thing-PlatForm) 90 arranged in the network 70, and the barrier device 100. The state information of 100 and the state information of the control device 300 are transmitted to the management server 80. For example, the barrier device 100 establishes a communication path 152 and a communication path 154, which are two sessions in the application layer, on one LTE communication line, and transmits the state information of the barrier device 100 via the communication path 152. , The state information of the control device 300 is transmitted via the communication path 154. The communication path 152 and the communication path 154 may be, for example, a communication path compliant with MQTT (Message Queuing Telemetry Transport).

Not limited to these, the state information of the control device 300 may include arbitrary information regarding the state of the control device 300.

The barrier device 100 may transmit state information indicating the state of the communication path 154 to the management server 80 via the communication path 152 together with the state information of the barrier device 100. It is configured to transmit the state information of the communication path 154 together with the state information of the barrier device 100 via the communication path 152 which is transmitted at a transmission interval shorter than the transmission interval of the state information of the control device 300 via the communication path 154. Therefore, the change in the state of the communication path 154 can be made known to the management server 80 at an early stage.

As described above, the barrier device 100 periodically transmits the state information of the barrier device 100 and the state information of the control device 300 to the management server 80, so that the state of the barrier device 100 and the state of the control device 300 are transmitted to the management server 80. Although the state can be appropriately grasped, the state of the control device 300 is not notified to the management server 80 when a problem occurs in information transmission by the communication path 154, for example, the communication path 154 is disconnected. If this happens, the service may be hindered. When the barrier device 100 according to the present embodiment detects that an obstacle has occurred in transmitting information through the communication path 154, such as detecting a disconnection of the communication path 154, the state information of the control device 300 is transmitted to the communication path. It may be transmitted via 152. Thereby, for example, when the communication path 154 is disconnected for some reason, it is possible to prevent the management server 80 from being unable to grasp the state of the control device 300.

Further, when the barrier device 100 detects that an obstacle has occurred in transmitting information through the communication path 152, such as detecting a disconnection of the communication path 152, the state information of the barrier device 100 is transmitted via the communication path 154.

Further, for example, the signal receiving unit 112 receives the authentication information release signal. Further, for example, the signal receiving unit 112 receives the signal of the initialization instruction of the control device 300.

The relay control unit 120 controls the wireless relay device 200. The relay control unit 120 causes, for example, the wireless relay device 200 to wirelessly transmit a signal to the control device 300. The relay control unit 120 may receive a signal wirelessly received by the wireless relay device 200 from the control device 300 from the wireless relay device 200.

The relay control unit 120 may control the plurality of wireless relay devices 200 in order to transmit the signal received by the signal reception unit 112 to each of the plurality of control devices 300. The relay control unit 120 may control the plurality of wireless relay devices 200 so that the timing of wirelessly transmitting signals to each of the plurality of control devices 300 is different.

The relay control unit 120 transmits signals to each of the plurality of wireless relay devices 200 at different timings by a predetermined time, so that each of the plurality of wireless relay devices 200 can be plurality of. The timing of wirelessly transmitting a signal to each of the control devices 300 of the above is changed.

The relay control unit 120 has a delay time setting unit 122. The delay time setting unit 122 sets the delay time for each of the plurality of wireless relay devices 200. The delay time setting unit 122 sets, for example, a delay time in each of the plurality of wireless relay devices 200, in which the ascending order number of the number of contacts of the plurality of contacts of the hub 104 is a multiplier. The relay control unit 120 may transmit a signal to each of the plurality of wireless relay devices 200 at a time delayed by the delay time having the ascending order number of the number of contacts of the plurality of contacts of the hub 104 as a multiplier.

The delay time setting unit 122 sets, for example, a delay time determined based on the port number of the hub 104 to which the wireless relay device 200 is connected to each of the plurality of wireless relay devices 200. The delay time setting unit 122 sets, for example, a time obtained by multiplying 500 milliseconds by a port number and adding 3000 milliseconds and a predetermined time as a delay time. As a specific example, the delay time setting unit 122 sets the delay time of each of the plurality of wireless relay devices 200 by using the following mathematical formula 1.

By setting the delay time based on the port number in this way, it is possible to set different delay times for each of the plurality of wireless relay devices 200. Further, by adding random times, for example, when two or more hubs 104 are used, the delay time set in the wireless relay device 200 connected to the port number 1 of the first hub 104 and the delay time are set. It is possible to prevent the delay time set in the wireless relay device 200 connected to the port number 1 of the second hub 104 from becoming the same, and wireless interference occurs between these wireless relay devices 200.

The signal may be transmitted at a time delayed by the delay time having the ascending order number of the number of the relay devices 200 as a multiplier. For example, when the target for transmitting a signal is six wireless relay devices 200, the delay time setting unit 122 sets a delay time in which a number from 1 to 6 is a multiplier for each of the six wireless relay devices 200. do. Further, for example, when the target for transmitting a signal is four wireless relay devices 200, the delay time setting unit 122 sets a delay time in which the numbers 1 to 4 are multipliers for each of the four wireless relay devices 200.

As a result, the delay time can be shortened as compared with the case where the port number is used. For example, when transmitting a signal to the wireless relay device 200 having port number 7 and the wireless relay device 200 having port number 8, if the port number is used, a delay time having 7 and 8 as a multiplier is set. By using the number of objects to which signals are transmitted, a delay time having 1 and 2 as a multiplier is set, and the delay time can be shortened.

The relay control unit 120 has a specific unit 124. The specifying unit 124 identifies the control device 300 that could not receive the signal after causing the plurality of wireless relay devices 200 to wirelessly transmit the signal received by the signal receiving unit 112 toward the plurality of control devices 300. For example, the identification unit 124 receives a response after a signal is wirelessly transmitted to each of the plurality of control devices 300 by each of the plurality of wireless relay devices 200 until a predetermined time elapses. If not, the control device 300 that did not receive the response is specified as the control device 300 that could not receive the signal.

On the other hand, the timing of wirelessly transmitting the signal may be controlled to be different. For example, the relay control unit 120 transmits the delay time set for each of the plurality of wireless relay devices 200 by the delay time setting unit 122 to each of the plurality of wireless relay devices 200, receives the signal, and then receives the signal. At the timing when the delay time has elapsed, the plurality of wireless relay devices 200 are controlled so as to transmit the signal to the control device 300.
