Abstract

Abstract: In order to avoid the accidents of working personnel caused by thermal stress in enclosed structure of shielding suit for live operation, a safety early warning system based on body signs was developed based on the thermal stress theory. Firstly, the state parameters of human body were analyzed and set as the threshold of the early warning system. Secondly, the safety warning method was proposed and the design idea was introduced from five module including power supply, microprocessor, Wireless Fidelity(WiFi) communication, data acquisition and alarm. Finally, the WiFi communication function test, the heart rate detecting function test and the high-voltage electric field experiment were carried out by using the sample machine. The results show that the proposed system's endurance capacity is greater than 8 h, that WiFi communication distance is greater than 15 m, that the heart rate error is less than 3%, and that it can work normally under 300 kV high pressure environment.

Key words: live working, thermal stress, body signs, safety early warning system, heart rate test
