Abstract: This paper developed a set of intelligent safety monitoring system with double line of defense used in high-voltage test site. Introduction was made to its work theory and the design scheme was given. The system was based on the technique of infrared detection, signal detection and processing etc., and it formed a dual protection area for warning and tripping through the unit-modularize design. In allusion to judging the situation of test locale personnel’s mis-entering area, the corresponding sound and light alarming or emergency trip action was implemented at last so as to avoid danger. The practical application proves the reliability and practicability of this system.
Key words: high-voltage test; double line of defense; intelligent safety monitoring system
