At the accident site, due to incomplete combustion, accidental leakage and other emergencies, a large amount of toxic gases (such as CO, H ₂ S, etc.) Protection is especially important. Traditional emergency rescue protective clothing (such as firefighting clothing) is a functional clothing that can only achieve basic functions such as fire prevention, heat insulation and flame retardancy, while environmental parameters such as the concentration of toxic gases in the rescue environment cannot be known in time by the on-site rescue team and rear commanders. . Therefore, it is very important to strengthen the personal protection of rescuers to ensure the safety of rescuers and the emergency command at the scene of the accident.

Electrochemical gas sensors use gas sensing electrodes or gas diffusion electrodes to form a series of batteries to measure various gas concentrations. The electrochemical sensor can accurately measure the concentration of trace gases (ppm level) in the air, such as CO, H ₂ S, SO ₂ , NH ₃ , HF and other corrosive or toxic gases. The electrochemical sensor has a small size and can be directly and quickly detected on site And unique advantages such as continuous detection. Compared with semiconductor gas sensors and infrared gas sensors, electrochemical sensors have the advantages of low power consumption and high linearity. A new generation of information processing integrated circuits (ICs) such as PSoC and Fusion FPGA rely on their highly integrated and highly reliable internal integrated circuits to achieve fast and accurate information processing at low power consumption and low cost. Wireless communication is a communication method that only uses electromagnetic waves in free space without passing through wired cables. With the rapid development of communication technology, people can rely on a new generation of wireless communication technology to exchange information in real time. Among them, ZigBee is a global wireless communication standard for wireless monitoring and control applications based on the IEEE802.15.4 standard. Control, medical care, remote control and other fields.

It is thanks to the rapid development of sensor technology, information processing technology and wireless communication technology that the informatization and intelligence of emergency rescue clothing become possible.
