The principle of work of electronic fence host is that after pulse producer energising, emission port forward end fence sends pulse voltage, about 1.5 seconds of time interval transmitting 1 time, about 0.1 second of the time that pulse stops on fence, on front end fence, form the receiving port that pulse is sent back to behind loop to main frame, this port receives the pulse signal feeding back, main frame also can be surveyed two resistance values between transmitting terminal simultaneously, if front end fence suffers to destroy to cause to open circuit or short circuit, the resistance that the receiving port of pulse main frame does not receive between pulse signal or two transmitting terminals is too little, main frame all can send warning.
Fence generally adopts 220V mains-supplied, and is furnished with the accumulator of special making, when having a power failure, is switched to storage battery power supply, switches back again mains-supplied after incoming call.According to traditional system setting, the frequency of high-voltage pulse signal is non-adjustable or adopt fork shift mode switching regulator, high-voltage pulse output frequency under 220V civil power or DC12V battery powered mode is identical, so not only to accumulator capacity, require larger, and greatly reduce service lifetime of accumulator, improve equipment operating cost.
