[0027] Figure 1 It is a structural schematic diagram of a gas detection system based on star flash communication provided according to an embodiment of the utility model. The gas detection system comprises: a gas detection controller 110, an intelligent alarm 120 and an intelligent valve 130;

[0028] The gas detection controller 110 establishes communication connections with the smart alarm 120 and the smart valve 130 respectively;

[0029] The smart alarm 120 is used to receive the gas concentration detection instruction sent by the gas detection controller 110; and is also used to send a smart valve disconnection instruction to the smart valve 130;

[0030] The smart valve 130 is used to receive the smart valve disconnection instruction sent by the smart alarm 120; it is also used to feedback the smart valve status to the smart alarm 120; it is also used to feedback the collected abnormal gas usage data to the gas detection controller 110;

[0031] Wherein, a communication connection is established between the smart alarm 120 and the smart valve 130 based on star flash communication.

[0032] In this embodiment, the intelligent alarm is controlled by a gas detection controller to detect the gas concentration corresponding to the current moment in real time, and abnormality judgment is performed based on the size of the gas concentration detection result.

[0033] Specifically, assuming that the abnormal gas concentration condition is Th and the gas concentration detection result is Th1, if Th1<Th, it means that the gas concentration detection result does not meet the abnormal gas concentration condition, and the gas concentration detection instruction sent by the gas detection controller continues to be received.

[0034] If Th1≥Th, it means that the gas concentration detection result meets the abnormal gas concentration condition, then the abnormal judgment result can be obtained, and the smart valve disconnection instruction is sent to the smart valve, and the sound and light alarm processing is performed, and the sound and light alarm information is fed back to the gas detection controller.

[0035] Furthermore, after the smart valve receives the smart valve disconnection instruction, the smart valve can be disconnected. Prior to this, the initial state of the smart valve needs to be obtained to perform the valve disconnection processing operation and feedback the smart valve state to the smart alarm. Correspondingly, the collected abnormal gas usage data can also be fed back to the gas detection controller.

[0036] Optionally, the smart valve is located between the gas meter and the gas-using device.

[0038] In this embodiment, the smart valve also needs to send heartbeat message information to the smart alarm according to a preset time period, and receive heartbeat message feedback information sent by the smart alarm to ensure that the smart alarm is online.

[0039] Specifically, assuming that the heartbeat message information is sent according to a time period T, when the smart alarm receives the heartbeat message information, it will send heartbeat message feedback information to the smart valve, so that the smart valve can determine that the smart alarm is online.

[0040] On the contrary, if the smart valve does not receive the heartbeat message feedback information within the preset time after sending the heartbeat message information to the smart alarm, the number of times the heartbeat message feedback information is not received is updated. Further, the heartbeat message information is sent to the smart alarm again. If the heartbeat message feedback information is not received within the preset number threshold, the smart valve can determine that the smart alarm is offline. If the smart valve determines that the smart alarm is offline, it will disconnect the smart valve and feedback to the gas detection controller.

[0044] Among them, the alarm star flash communication unit can be used for interactive communication with the valve star flash communication unit.
