Embodiment

[0027] Example: such as Figure 1 to Figure 4 As shown in the figure, an accelerometer array-based explosive shock debris protective clothing positioning alarm system is mainly composed of a sensor node unit 1, a flexible substrate 3 laid with serpentine copper wires 2, firefighter protective clothing, a signal processing unit, a data It consists of analysis unit, wireless transmission unit, upper computer display unit and alarm unit. The sensor node unit 1 is installed on the above-mentioned flexible substrate 3 and closely attached to the above-mentioned protective clothing for detecting the collision position and intensity of the explosive fragments and the above-mentioned protective clothing. The above-mentioned sensor node unit uses a MEMS acceleration sensor as a sensing node, It does not affect the normal work of firefighters. It can not only monitor the personal safety of firefighters in real time, but also alert firefighters and commanders to take rescue measures in t...

Abstract

The invention discloses an explosive impact fragment protection suit positioning alarm system based on an accelerometer array, and the system comprises a sensor node unit, a flexible substrate, a protection suit, a signal processing unit, a data analysis unit, a wireless transmission unit, an upper computer display unit, and an alarm unit. The sensor node unit is mounted on the flexible substrate and is attached to the protective clothing; the signal processing unit is used for acquiring output signals of the plurality of sensor node units closest to the collision position of the explosive fragments and the work clothes; the data analysis unit calculates the collision position and amplitude according to the amplitude of the output signal, and transmits the collision position and amplitude to the upper computer display unit through the wireless transmission unit; and the collision position and amplitude are combined to give an alarm in a grading manner through the alarm unit. According to the system, the danger degree of the firefighter is digitized and visualized, accurate information is provided for on-site commanders to quickly make decisions and command emergency rescue, and the personal safety of the firefighter is guaranteed as much as possible.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring of protective clothing, in particular to an accelerometer array-based positioning and alarm system for explosive impact fragment protective clothing. Background technique [0002] With the rapid development of the economy, the number of large buildings is increasing, which also leads to the frequent occurrence of large fires, and even explosion accidents in severe cases. Firefighters who are responsible for fire fighting and rescue work will be in a very dangerous situation, and their personal safety is greatly threatened in severe fire scenes. Personal injury accidents during firefighter operations have always been the focus of social attention. Once firefighters are in distress during an explosion accident, if they cannot be rescued within a short period of time, serious casualties will result. At this time, firefighters Injury information is particularly important. However, the...
