[0025] See also Figure 1 , Figure 1 A schematic structural diagram of a gas detector provided in an embodiment of the present application, such as Figure 1 As shown, the gas detector 11 may include a hydrogen sensor 111 , a carbon monoxide sensor 112 , a VOC sensor 113 , a smoke sensor 114 , a temperature sensor 115 and a processor 116 .

[0026] The processor 116 is connected to the hydrogen sensor 111 , the carbon monoxide sensor 112 , the VOC sensor 113 , the smoke sensor 114 and the temperature sensor 115 .

[0027] Specifically, the first end of the processor 116 is connected to the hydrogen sensor 111, the second end of the processor 116 is connected to the carbon monoxide sensor 112, the third end of the processor 116 is connected to the VOC sensor 113, the fourth end of the processor 116 is connected to the smoke sensor 114, and the fifth end of the processor 116 is connected to the temperature sensor 115.

[0028] The hydrogen sensor 111 is used to collect hydrogen in the environment, generate a signal for describing the concentration of hydrogen in the environment based on the collected hydrogen, and send the signal for describing the concentration of hydrogen in the environment to the processor 116.

[0029] The carbon monoxide sensor 112 is used to collect carbon monoxide in the environment, generate a signal describing the concentration of carbon monoxide in the environment based on the collected carbon monoxide, and send the signal describing the concentration of carbon monoxide in the environment to the processor 116 .

[0030] The VOC sensor 113 is used to collect volatile organic compounds in the environment, generate a signal for describing the concentration of the volatile organic compounds in the environment according to the collected volatile organic compounds, and send the signal for describing the concentration of the volatile organic compounds in the environment to the processor 116 .

[0031] The smoke sensor 114 is used to collect smoke in the environment, generate a signal for describing the smoke concentration in the environment according to the collected smoke, and send the signal for describing the smoke concentration in the environment to the processor 116 .

[0032] The temperature sensor 115 is used to detect the ambient temperature, generate a signal describing the ambient temperature, and send the signal describing the ambient temperature to the processor 116 .

[0033] Exemplarily, the temperature sensor 115 is used to generate a voltage value for describing the ambient temperature according to the ambient temperature, and send the voltage value for describing the ambient temperature to the processor 116 .

[0034] The processor 116 is used to receive a signal sent by the hydrogen sensor 111 for describing the hydrogen concentration in the environment, and determine whether the hydrogen concentration in the environment is greater than a preset hydrogen concentration threshold according to the signal for describing the hydrogen concentration in the environment.

[0035] The processor 116 is further configured to receive a signal sent by the carbon monoxide sensor 112 for describing the carbon monoxide concentration in the environment, and determine whether the carbon monoxide concentration in the environment is greater than a preset carbon monoxide concentration threshold value based on the signal for describing the carbon monoxide concentration in the environment.

[0036] The processor 116 is further configured to receive a signal sent by the VOC sensor 113 for describing the concentration of volatile organic compounds in the environment, and determine whether the concentration of volatile organic compounds in the environment is greater than a preset volatile organic compound concentration threshold value based on the signal for describing the concentration of volatile organic compounds in the environment.

[0037] The processor 116 is further configured to receive a signal sent by the smoke sensor 114 for describing the smoke concentration in the environment, and determine whether the smoke concentration in the environment is greater than a preset smoke concentration threshold value based on the signal for describing the smoke concentration in the environment.

[0038] The processor 116 is further configured to receive a signal sent by the temperature sensor 115 for describing the ambient temperature, and determine whether the ambient temperature is greater than a preset temperature threshold according to the signal for describing the ambient temperature.

[0039] Exemplarily, the processor 116 is used to receive a voltage value for describing the ambient temperature sent by the temperature sensor 115, and determine whether the ambient temperature is greater than a preset temperature threshold based on a voltage value threshold corresponding to the voltage value for describing the ambient temperature and the temperature threshold.

[0040] It can be seen from the above that the gas detector provided in the embodiment of the present application includes a hydrogen sensor, a carbon monoxide sensor, a VOC sensor, a smoke sensor, a temperature sensor and a processor; the processor is connected to the hydrogen sensor, the carbon monoxide sensor, the VOC sensor, the smoke sensor and the temperature sensor. Since the gas detector provided in the present application includes a hydrogen sensor, a carbon monoxide sensor, a VOC sensor, a smoke sensor, a temperature sensor and a processor, it is not necessary to use multiple gas detectors at the same time to simultaneously detect hydrogen, carbon monoxide, VOC, smoke and temperature in the environment, thereby improving the convenience of the gas detector.

[0041] See also Figure 2 , Figure 2 A schematic structural diagram of a gas detector provided in another embodiment of the present application is shown in FIG. Figure 2 As shown, the gas detector 11 may further include a communication device 117 . The communication device 117 may be connected to the processor 116 .

[0042] In the embodiment of the present application, the communication device 117 may include a first communication module 1171 , a second communication module 1172 and a third communication module 1173 .

[0043] The first communication module 1171 can be connected to the cloud platform through the gateway system. Specifically, the first communication module 1171 can be connected to the gateway system for communication, and the gateway system can be connected to the cloud platform for communication. In a possible implementation, the first communication module 1171 can be a controller area network (CAN) interface.

[0044] The processor 116 can send the acquired signals and data to the cloud platform in real time through the first communication module 1171 and the gateway system. After receiving the real-time signals and data, the cloud platform can organize, analyze and store the received signals and data.

[0045] The cloud platform can also determine whether there is any abnormality in the environment where the gas detector 11 is located based on the received signals and data. If the cloud platform determines that there is any abnormality in the environment where the gas detector 11 is located, the cloud platform can remind the user that there is any abnormality in the environment where the gas detector 11 is located through a preset reminder method (such as sending a prompt message or outputting a prompt sound, etc.).

[0046] In addition, the cloud platform can also be used to remotely upgrade the gas detector 11. Specifically, when the gas detector 11 needs to be upgraded, the cloud platform can send the upgrade package to the processor 116 through the gateway system and the first communication module 1171 to instruct the processor 116 to upgrade. By upgrading through remote upgrade, there is no need for personnel to go to the site to upgrade the gas detector 11, which reduces the operation and maintenance costs.

[0047] The second communication module 1172 may be connected to the battery charge and discharge management system. In a possible implementation, the second communication module 1172 may be a CAN interface.

[0048] The gas detector 11 may be disposed in the energy storage power station and may detect hydrogen, carbon monoxide, VOC, smoke and temperature in the energy storage power station.

[0049] If the gas detector 11 determines that an abnormality occurs in the environment of the energy storage power station where the gas detector 11 is located (such as a hydrogen concentration greater than a hydrogen concentration threshold, a carbon monoxide concentration greater than a carbon monoxide concentration threshold, a VOC concentration greater than a volatile organic compound concentration threshold, a smoke concentration greater than a smoke concentration threshold, or a temperature greater than a temperature threshold), the gas detector 11 can send an environmental abnormality signal indicating that an environmental abnormality has occurred to the battery charge and discharge management system through the processor 116. After receiving the environmental abnormality signal, the battery charge and discharge management system can control the batteries in the energy storage power station.

[0050] Exemplarily, when the gas detector 11 determines that the ambient temperature is too high, the battery charge and discharge management system can reduce the charging current or discharging current of the battery. When the gas detector 11 determines that the hydrogen concentration in the environment is too high, or the carbon monoxide concentration in the environment is too high, or the VOC concentration in the environment is too high, or the smoke concentration in the environment is too high, the battery charge and discharge management system can control the battery to stop charging or discharging by cutting off the power supply connected to the battery.

[0051] The third communication module 1173 may be connected to a fire protection system. In a possible implementation, the third communication module 1173 may be a 485 interface.

[0052] The processor 116 can send a fire instruction to the fire system through the third communication module 1173.

[0053] The fire fighting system can receive the fire fighting instruction sent by the gas detector 11 and take corresponding fire fighting actions according to the fire fighting instruction sent by the gas detector 11.

[0054] For example, if the processor 116 determines that the hydrogen concentration in the environment is greater than the hydrogen concentration threshold, or the carbon monoxide concentration in the environment is greater than the carbon monoxide concentration threshold, or the VOC concentration in the environment is greater than the VOC concentration threshold, or the smoke concentration in the environment is greater than the smoke concentration threshold, the processor 116 can send a fire extinguishing instruction to the fire fighting system to instruct the fire fighting system to perform a fire extinguishing operation. For example, the fire fighting system can perform a fire extinguishing operation by releasing perfluorohexanone or fine water mist.

[0055] For example, if the processor 116 determines that the ambient temperature is greater than the temperature threshold, the processor 116 may send a cooling instruction to the fire fighting system to instruct the fire fighting system to perform a cooling operation. For example, the fire fighting system may perform a cooling operation by turning on an air cooling system or a water cooling system.

[0056] In the embodiment of the present application, the gas detector 11 may further include an audible and visual alarm 118. The audible and visual alarm 118 may be connected to the processor 116.

[0057] The processor 116 may send an alarm instruction to the sound and light alarm 118 to instruct the sound and light alarm 118 to perform a corresponding alarm action.

[0058] For example, if the processor 116 determines that the hydrogen concentration in the environment is greater than the hydrogen concentration threshold, or determines that the carbon monoxide concentration in the environment is greater than the carbon monoxide concentration threshold, or determines that the VOC concentration in the environment is greater than the VOC concentration threshold, or determines that the smoke concentration in the environment is greater than the smoke concentration threshold, or determines that the ambient temperature is greater than the temperature threshold, the processor 116 can send an alarm instruction to the sound and light alarm 118.

[0059] The sound and light alarm 118 can receive the alarm instruction sent by the processor 116 and make corresponding alarm actions. The specific alarm action made by the sound and light alarm 118 can be set according to actual needs. For example, if the processor 116 determines that the hydrogen concentration in the environment is greater than the hydrogen concentration threshold, the sound and light alarm 118 can broadcast a voice signal of "hydrogen concentration is too high" and flash a red light; if the processor 116 determines that the carbon monoxide concentration in the environment is greater than the carbon monoxide concentration threshold, the sound and light alarm 118 can broadcast a voice signal of "carbon monoxide concentration is too high" and flash a red light, and so on.

Figure 3 As shown, the gas detection system 31 may include a plurality of gas detectors 11 , a gateway system 311 , a cloud platform 312 , a battery charge and discharge management system 313 , and a fire protection system 314 .

[0061] Among them, the gateway system 311 can be communicated with each gas detector 11, the cloud platform 312 can be communicated with the gateway system 311, the battery charge and discharge management system 313 can be communicated with each gas detector 11, and the fire protection system 314 can be communicated with each gas detector 11.

[0062] The number of gas detectors 11 can be set according to actual needs.

[0063] The following combination Figure 3 , the specific working principle of the gas detection system provided in the embodiment of the present application is described in detail.

[0064] Exemplarily, when gas detection is required for an energy storage power station, a plurality of gas detectors 11 may be arranged at different locations of the energy storage power station.

[0065] The hydrogen sensor 111 in any gas detector 11 can send a signal to the processor 116 of the gas detector 11 for describing the hydrogen concentration in the environment, the carbon monoxide sensor 112 in any gas detector 11 can send a signal to the processor 116 of the gas detector 11 for describing the carbon monoxide concentration in the environment, the VOC sensor 113 in any gas detector 11 can send a signal to the processor 116 of the gas detector 11 for describing the volatile organic compound concentration in the environment, the smoke sensor 114 in any gas detector 11 can send a signal to the processor 116 of the gas detector 11 for describing the smoke concentration in the environment, and the temperature sensor 115 in any gas detector 11 can send a signal to the processor 116 of the gas detector 11 for describing the ambient temperature.

[0066] The processor 116 in any gas detector 11 can determine whether the hydrogen concentration in the environment is greater than the preset hydrogen concentration threshold based on the received signal, and can determine whether the carbon monoxide concentration in the environment is greater than the preset carbon monoxide concentration threshold, and can determine whether the volatile organic compound concentration in the environment is greater than the preset volatile organic compound concentration threshold, and can also determine whether the smoke concentration in the environment is greater than the preset smoke concentration threshold, and can also determine whether the ambient temperature is greater than the preset temperature threshold.

[0067] If the processor 116 in any gas detector 11 determines that the hydrogen concentration in the environment is greater than the hydrogen concentration threshold, or determines that the carbon monoxide concentration in the environment is greater than the carbon monoxide concentration threshold, or determines that the VOC concentration in the environment is greater than the VOC concentration threshold, or determines that the smoke concentration in the environment is greater than the smoke concentration threshold, the processor 116 in the gas detector 11 can send a fire extinguishing instruction to the fire protection system 314, send an alarm instruction to the sound and light alarm 118, and send an environmental abnormality signal to the battery charge and discharge management system 313.

[0068] If the processor 116 in any gas detector 11 determines whether the ambient temperature is greater than a preset temperature threshold, the processor 116 in the gas detector 11 can send a cooling instruction to the fire protection system 314, send an alarm instruction to the sound and light alarm 118, and send an environmental abnormality signal to the battery charge and discharge management system 313.

[0069] After the fire fighting system 314 receives the cooling instruction, the fire fighting system 314 can perform the cooling operation. And after the fire fighting system 314 receives the fire extinguishing instruction, the fire fighting system 314 can perform the fire extinguishing operation.

[0070] After receiving the alarm instruction, the sound and light alarm 118 can make corresponding alarm actions.

[0071] After receiving the abnormal environment signal, the battery charge and discharge management system 313 may reduce the charging current or discharging current of the battery, or may cut off the power supply connected to the battery to control the battery to stop charging or discharging.

[0072] In addition, the processor 116 in each gas detector 11 can also send the received signals and data to the cloud platform 312 in real time through the gateway system 311.

[0073] The cloud platform 312 can receive the signals and data sent by the processor 116 in each gas detector 11, and determine whether there is an abnormality in the environment where the gas detector 11 is located based on the received signals and data. If the cloud platform 312 determines that there is an abnormality in the environment where the gas detector 11 is located, the cloud platform 312 can remind the user that there is an abnormality in the environment where the gas detector 11 is located through a preset reminder method (such as sending a prompt message or outputting a prompt sound, etc.).

[0074] In addition, the cloud platform 312 can also be used to remotely upgrade each gas detector 11. Specifically, when a gas detector 11 needs to be upgraded, the cloud platform 312 can send an upgrade package to the processor 116 of the gas detector 11 through the gateway system 311 and the first communication module 1171 to instruct the processor 116 of the gas detector 11 to upgrade.
