[0049] In some embodiments, the processor 105 is also configured to control the start and stop of the motor and the connection and disconnection of the cable in response to a remote control command triggered by a user.

[0050] The remote control command can include control information sent to specified motors and cables. For example, when a user determines that a cable fire has occurred in the plant based on alarm information, the user can control the start and stop of one or more motors, as well as the on / off state of one or more cables. Subsequently, based on the fire information, manual inspections can be carried out on motors and cables in areas where no fire has occurred to reduce the probability of fire in the plant.

[0051] The following is combined with Figure 5 The fire control system shown is described below. The working principle of the fire control system 100 is explained as follows:

[0052] First, the first temperature T1 of the cable is obtained by the thermistor 1011 arranged on the surface of the cable in the power plant, and the second temperature T2 of the motor is obtained by the infrared temperature measuring device 1012 arranged on the surface of the motor in the power plant. The temperature measuring device 101, including the thermistor 1011 and the infrared temperature measuring device 1012, transmits the first temperature T1 and the second temperature T2 to the processor 105 through a wireless network.

[0053] Meanwhile, the ambient humidity RH of the environment where the cable is located is obtained by a humidity measuring instrument 102 that is evenly distributed in the cable trench, and the obtained ambient humidity RH is transmitted to the processor 105 via a wireless network.

[0054] Meanwhile, gas sensors 103, located at the motor's air inlet and outlet, the connection between the cable and the motor, and the top and bottom of the cable trench, acquire the smoke concentration c1, hydrocarbon gas concentration c2, and halogen acid gas concentration c3 of the environment where the cable is located. The acquired smoke concentration c1, hydrocarbon gas concentration c2, and halogen acid gas concentration c3 are then transmitted to the processor 105 via a wireless network. The gas sensors 103 include a smoke sensor 1031, a hydrocarbon gas sensor 1032, and a halogen acid gas sensor 1033. The smoke sensor 1031 is used to acquire the smoke concentration c1, the hydrocarbon gas sensor 1032 is used to acquire the hydrocarbon gas concentration c2, and the halogen acid gas sensor 1033 is used to acquire the halogen acid gas concentration c3.

[0055] Meanwhile, video information of the cable is acquired by a camera device 104 installed at the top of the cable trench, and the acquired video information is transmitted to the processor 105 via a wireless network.

[0056] Secondly, the processor 105 analyzes the first temperature T1, the second temperature T2, the ambient humidity RH, the smoke concentration c1, the hydrocarbon gas concentration c2, the halogen acid gas concentration c3 and the video information relative to the change information of the reference data by the analysis module 1051, and determines that the change information is analyzed when one or more of the following conditions is analyzed: the deviation rate of the first temperature T1 relative to the reference first temperature T a is greater than the set change threshold; the deviation rate of the second temperature T2 relative to the reference second temperature T b is greater than the set change threshold; the deviation rate of the ambient humidity RH relative to the reference ambient temperature RH0 is greater than the set change threshold; the deviation rate of the smoke concentration c1 relative to the reference smoke concentration c a is greater than the set change threshold; the deviation rate of the hydrocarbon gas concentration c2 relative to the reference hydrocarbon gas concentration c b is greater than the set change threshold; the deviation rate of the halogen acid gas concentration c3 relative to the reference halogen acid gas concentration c c is greater than the set change threshold; and smoke appears near the cable in the video information and the cable appears to be burnt in the historical video.

[0057] Finally, after determining that the analysis module 1051 analyzes the change information, the control module 1052 triggers the fire extinguishing instruction including the fire extinguishing location, and the fire extinguishing device 106 moves to the fire extinguishing location in the fire extinguishing instruction at a preset speed. After moving to the fire extinguishing location, the fire extinguishing device 106 sprays dry powder extinguishing agent to the burning place of the cable, and the spraying time and the total amount of spraying are adjusted according to the severity of the fire, wherein the severity of the fire is determined by the smoke concentration and the smoke height and the burnt degree in the video information.

[0058] In this way, the temperature, humidity, gas and video of the cable and the motor connected to the cable in the power station are comprehensively monitored, so that the inspection range covers the entire station, and the accuracy and efficiency of fire identification in complex environment are effectively improved. At the same time, the movable fire extinguishing device can execute the fire extinguishing operation, so that the fire can be handled in time and the fire handling efficiency is improved.

Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0060] In addition, it should be noted that various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction.
