[0041] Figure 3 It is a structural schematic diagram of an electronic device provided in an embodiment of the present application. DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In one embodiment, the present invention provides a generator excitation side fire protection method, which can be implemented by a generator excitation side fire protection device. The generator excitation side fire protection device can be implemented by software and / or hardware.

[0044] like Figure 1 As shown, the fire prevention method for the generator excitation side of the embodiment of the present invention specifically includes the following steps:

[0045] S110, obtaining hydrogen content data in a generator room where a target generator is located and temperature data of the generator room;

[0046] Exemplarily, by evaluating the safety status of the generator room where the target generator is located through a variety of data, more scenarios can be addressed, that is, the method can be directed to the scenario of hydrogen leakage as well as the scenario of fire in the generator room.

[0047] S120, comparing the hydrogen content data with a preset hydrogen content threshold to obtain a first comparison result, and comparing the temperature data with a preset temperature threshold to obtain a second comparison result;

[0048] S130: if the first comparison result is used to indicate that the hydrogen content data is greater than or equal to a preset hydrogen content threshold value and / or the second comparison result is used to indicate that the temperature data is greater than or equal to a preset temperature threshold value, then acquiring image data of the generator room, and determining whether there is a person in the generator room based on the image data by using image recognition technology;

[0049] Exemplarily, the hydrogen content data and the temperature data are first judged. If the first comparison result is used to characterize that the hydrogen content data is greater than or equal to a preset hydrogen content threshold and / or the second comparison result is used to characterize that the temperature data is greater than or equal to a preset temperature threshold, the image data of the generator room is then acquired. When both the hydrogen content data and the temperature data exceed the corresponding thresholds, it is proved that the generator room is safe, that is, there is no need to determine whether there is anyone in the generator room, and there is no need to acquire the image data of the generator room, thereby avoiding the data storage pressure caused by real-time acquisition of the image data of the generator room.

[0050] S140, if there is a person in the generator room, generate an alarm message;

[0051] S150: If there is no person in the generator room, control the gas spray device in the generator room to release flame-retardant gas to fill the generator room.

[0052] By obtaining the hydrogen content data in the generator room where the target generator is located and the temperature data of the generator room; comparing the hydrogen content data with the preset hydrogen content threshold to obtain a first comparison result, and comparing the temperature data with the preset temperature threshold to obtain a second comparison result; if the first comparison result is used to characterize that the hydrogen content data is greater than or equal to the preset hydrogen content threshold and / or the second comparison result is used to characterize that the temperature data is greater than or equal to the preset temperature threshold, then obtaining the image data of the generator room, and judging whether there is a person in the generator room based on the image data by image recognition technology; if there is a person in the generator room, an alarm message is generated; if there is no person in the generator room, the gas spray device in the generator room is controlled to release flame-retardant gas to fill the generator room. By real-time monitoring of the hydrogen content and temperature changes in the generator excitation side area, timely and effective early warning of fire prevention is ensured in a safe and unmanned environment, thereby effectively preventing and dealing with potential safety hazards caused by hydrogen leakage.

[0053] In a possible implementation manner, the step of obtaining hydrogen content data in a generator room where a target generator is located includes:

[0054] Acquiring initial hydrogen content data at different positions in the generator room to obtain an initial hydrogen content set;

[0055] A maximum value is selected from the initial hydrogen content set as the hydrogen content data in the generator room where the target generator is located.

[0056] Exemplarily, by acquiring initial hydrogen content data at different locations in the generator room and selecting the maximum value therein as the hydrogen content data in the generator room where the target generator is located, inaccurate detection results caused by uneven hydrogen distribution can be avoided, and failure in hydrogen leakage detection can be more reliably avoided.

[0057] In a possible implementation manner, the step of obtaining hydrogen content data in the generator room where the target generator is located further includes:

[0058] The average hydrogen content at different positions in the generator room is calculated according to the initial hydrogen content set, and the average hydrogen content is used as the hydrogen content data in the generator room where the target generator is located.

[0059] For example, when the generator room is large, in order to reduce the cost pressure caused by adding sensors, the average hydrogen content at different positions in the generator room is calculated as the hydrogen content data in the generator room where the target generator is located, thereby saving costs while ensuring reliable hydrogen leakage detection.

[0060] In a possible implementation manner, the step of generating an alarm message if there is a person in the generator room includes:

[0061] If there is a person in the generator room, identifying the person's posture information based on the image data and a preset posture recognition model;

[0062] Generate warning information according to the posture information and preset warning rules.

[0063] Exemplarily, generating different alarm information for personnel in different postures is conducive to being applicable to more specific scenarios. Using different alarm information for different specific scenarios is conducive to the staff to understand the safety status of the generator room in a timely manner.

[0064] In a possible implementation manner, the step of generating alarm information according to the posture information and a preset alarm rule includes:

[0065] The posture information is matched with the preset posture information in the preset alarm rule. If the posture information is consistent with the preset posture information, alarm information is generated according to the preset alarm mode corresponding to the preset posture information in the preset alarm rule.

[0066] Exemplarily, when the posture information of the person represents a lying posture, and the preset posture information in the preset alarm rule is also a lying posture, the alarm information is generated according to the preset alarm method corresponding to the lying posture in the preset alarm rule.

[0067] In a possible implementation manner, the step of generating alarm information according to a preset alarm mode corresponding to the preset posture information in the preset alarm rule includes:

[0068] Generate an alarm instruction based on a warning mode in the preset alarm mode, wherein the warning mode includes at least one of a light warning and a sound warning;

[0069] The alarm information is generated according to the identification information of the preset alarm target in the preset alarm mode and the alarm instruction.

[0070] Exemplarily, when the posture information of a person represents a lying posture, the preset posture information in the preset alarm rule is also a lying posture, and the warning method in the preset alarm method adopts light warning and sound warning to wake up the person by light and sound. Because the alarm information may not be obtained when the posture information of the person represents a lying posture, and thus other people's help is needed, a preset alarm target is set. For example, the preset alarm target is set to a doctor, a manager, etc., and the alarm information is generated according to the identification information of the preset alarm target and the alarm instruction, so that the alarm information is sent to the preset alarm target.

[0071] In a possible implementation manner, the method further includes:

[0072] When the hydrogen content data is less than a preset hydrogen content threshold, and the temperature data is less than a preset temperature threshold, the gas spray device is controlled to be closed.

[0073] Second, as Figure 2 As shown, the present application provides a generator excitation side fire protection system, the system comprising:

[0074] Target generator 3, hydrogen content sensor, gas spray device 6, visual PTZ / infrared temperature measuring device 7 and control unit 2;

[0075] The gas nozzle of the gas spray device 6 is arranged at the top of the discharge machine room 1 where the target generator 3 is located, and the gas spray device 6 is used to release flame-retardant gas to fill the generator room 1;

[0076] The hydrogen content sensor is arranged in the generator room 1 where the target generator 3 is located;

[0077] The visual pan / tilt / infrared temperature measuring device 7 is arranged at the top of the generator room 1, and the visual pan / tilt / infrared temperature measuring device 7 is used to obtain the temperature data of the generator room 1, and the visual pan / tilt / infrared temperature measuring device 7 is also used to obtain the image data of the generator room 1;

[0078] The control unit 2 is data-connected with the hydrogen content sensor, the gas spray device 6 , and the visual pan / infrared temperature measuring device 7 , respectively.

[0079] In a possible implementation manner, the gas spray device includes at least two gas spray heads, and the gas spray heads are symmetrically arranged on both sides of the target generator.

[0080] Exemplarily, by symmetrically arranging the gas nozzles on both sides of the target generator, it is possible to avoid the problem that the flame-retardant gas ejected from a single gas nozzle is difficult to quickly reach the other side of the target generator when the target generator is blocked.

[0081] In a possible implementation manner, the generator excitation side fire protection system includes at least two hydrogen content sensors, wherein the first hydrogen content sensor 4 is arranged on the target generator, and the second hydrogen content sensor 5 is arranged on the base of the target generator.
