| description | An infrared warning guard fence is characterized by comprising fence racks provided with infrared emission detectors. The fence racks are connected by warning bands, the infrared detectors are connected with each other by signal wires, and the infrared detectors are connected with an intelligent warning main unit and an electric leakage circuit breaker by signal wires. Each infrared emission detector includes both an emitter and a receiver, a normally closed contact of each infrared detector (or a fence) is converted into an open contact when an infrared pulse light beam between the emitter and the receiver is shielded, so that a warning signal is generated for the warning main unit, simultaneously, the warning main unit outputs a short circuit signal to the electric leakage circuit breaker, and the electric leakage circuit breaker is tripped to function in protection. The adopted infrared warning guard fence realizes warning and cutting off of a test power supply when a test zone is invaded, prevents persona |
