Figure 1 A harmful gas early warning system is provided, which includes at least a harmful gas detection device, a positioning device and a transmission device, which are described in detail as follows:

[0035] At least one hazardous gas detection device comprises a hollow housing, the housing being equipped with a positioning assembly for determining a worker's position, a detection assembly for detecting hazardous gas concentrations, a controller, and a clip. The controller is electrically connected to the positioning assembly and the detection assembly. The hollow housing can be rectangular or cylindrical. The hazardous gas can be one or more of carbon monoxide, hydrogen sulfide, hydrogen cyanide, methane, propane, pentane, chlorine, and ammonia. The controller processes data from the positioning assembly and the detection assembly.

[0036] At least one positioning device is installed at a predetermined location in the workshop, and the positioning device and the positioning assembly are compatible. The predetermined location can be an area corresponding to equipment that uses or stores hazardous gases, such as a multi-level platform for heating furnace gas equipment. The positioning device and the positioning assembly are compatible, and it can be understood that the positioning device and the positioning assembly cooperate with each other to determine the position of the worker.

[0037] At least one transmission device is communicatively connected to the controller and the backend server. The transmission device can transmit data from the controller to the backend server, or transmit data from the backend server to the controller.

[0038] In some embodiments, the harmful gas detection device includes a first communication module, the transmission device includes a second communication module, and the background server includes a third communication module. The transmission device and the controller are communicated through the first communication module and the second communication module, and the transmission device and the background server are communicated through the second communication module and the third communication module.

[0039] In some embodiments, the detection component includes: an air intake pipe connecting the inner and outer sides of the hollow shell; a sampling tube, which is provided with a harmful gas sensor; and an air intake pump, which is provided in the hollow shell, wherein the inlet of the air intake pump is connected to the internal space of the hollow shell, and the outlet is connected to the sampling tube. The harmful gas sensor can be an electrochemical gas sensor suitable for detecting reducing gases such as carbon monoxide, hydrogen sulfide, and ammonia, or a photoionization gas sensor. When the air intake pump is started, the gas in the atmosphere passes through the air intake pump and the sampling tube in sequence from the air intake pipe. The harmful gas sensor in the sampling tube detects the harmful gas in the inhaled gas, and the controller processes the detection data to obtain the concentration of the harmful gas.

[0040] In some embodiments, the hollow housing is further provided with an emergency call button, a microphone, and a speaker. The emergency call button, the microphone, and the speaker are all electrically connected to the controller. The backend server includes a voice response module, and the voice response module and the controller are communicatively connected via the transmission device. When the emergency call button is pressed, the controller sends an emergency call signal to the backend server via the transmission device so that other personnel can provide rescue. The staff can communicate with other personnel on the backend server through the microphone and the speaker, wherein the microphone is used to receive the staff's voice and the speaker is used to play the voices of other personnel on the backend server.

[0041] In some embodiments, a lithium battery is further disposed within the hollow housing and is electrically connected to the positioning assembly, the detection assembly, and the controller.

The video recording component may include multiple video cameras located at predetermined locations. Other personnel on the backend server can use the video recording component to observe the work area and, if a worker in one area is in danger, promptly notify workers in other areas to provide rescue assistance.

[0043] In some embodiments, the backend server includes a display module having an electronic map built in. When the transmission device sends the worker's location to the backend server, the electronic map can display the worker's location.

[0044] In some embodiments, the transmission device and the backend server are connected via 4G or 5G signals. Using 4G or 5G signals for data transmission can ensure the stability and real-time performance of data transmission at long distances.

[0045] In some embodiments, the transmission device and the harmful gas detection device are connected via a radio frequency carrier signal. When the signal in the field is poor, the transmission device can also perform well on the data of the harmful gas detection device.

[0046] In some embodiments, the hazardous gas detection device further includes an alarm component that generates an alarm when hazardous gas levels exceed a specified limit, and the alarm component is electrically connected to the controller. When the hazardous gas levels exceed a specified limit, the alarm component generates an alarm. Upon receiving the alarm, personnel evacuate the site or call for help using an emergency button. Simultaneously, the alarm information is transmitted to the backend server via a transmission device, allowing other personnel on the backend server to be notified.
