Abstract

부하의 전류를 일정비율로 변환시킬 수 있도록 된 전류변환기, 이 전류변환기의 2차측에 연결되어 발생된 AC 출력전압을 일정레벨의 DC전압으로 정류하도록 된 정류부, 그리고 이 정류부에 의해 평활된 아날로그의 신호를 디지탈신호로 변환시켜 주도록 된 A/D컨버터, 이 A/D컨버터 로부터 출력된 디지탈신호를 내장된 프로그램에 따라 판별하여 각 부하의 성능 혹은 고장유무를 검출하도록 된 마이컴, 또한 이 마이컴에 의해 검출된 각 부하의 판단결과를 외부로 표시하도록 된 표시부로 이루어져 각 부하에서 발생되는 부하전류를 셋팅된 프로그램에 따라 각각 판별하고 그 판별된 결과치를 외부로 표시되도록 함으로써, 각 부품의 동작상태를 쉽게 판별할 수 있도록 됨으로 회로의 동작성능을 감지할 수 있도록 됨은 물론 그에 따라 부품고장시 발생되던 오동작도 방지시킬 수 있다.A current converter capable of converting the load current to a constant ratio, a rectifier connected to the secondary side of the current converter to rectify the generated AC output voltage into a DC voltage of a constant level, and an analog smoothed by the rectifier. A / D converter which converts signal into digital signal, Micom which detects the performance or failure status of each load by discriminating the digital signal output from this A / D converter according to the built-in program. The display unit is configured to display the detected result of each detected load to the outside, so that the load current generated from each load can be determined according to the set program, and the determined result is displayed to the outside. It is possible to detect the operation performance of the circuit, as well as to detect the failure Malfunctions can also be prevented.

Claims

A current converter 1 capable of converting the current of the load to a constant ratio, a rectifier 2 connected to the secondary side of the current converter 1 to rectify the generated AC output voltage to a DC voltage of a predetermined level, The A / C converter 3, which converts the analog signal smoothed by the rectifier 2 into a digital signal, and the digital signal output from the A / C converter 3 are discriminated according to the built-in program. The microcomputer 4 is configured to detect the performance or the presence or failure of each load, and the display unit 5 is configured to display the determination result of each load detected by the microcomputer 4 to the outside. Magnetic check function circuit of equipped electronic equipment

Initializing the micro register and the check data by the self-checking function mode is set, and if the step proceeds, turn off the connection switches (SWn) of all loads and turn on only the connection switches of the loads to be checked. Checking the value, comparing the value of the load current checked during the step with the normal load current value set in advance to determine the performance and failure of the load, and determining the value of the load determined by the step The display of the determination result to the outside, and if the checking operation of the individual load set in the step is completed, the step of setting the load to be checked next and repeating the above steps, the magnetic of the electronic device equipped with a microcomputer Degaussing method of checking function circuit

The electronic device of claim 2, wherein the comparing of the currently checked load current value with a preset normal load current value is subdivided into a plurality of check steps for an accurate checking operation. Control method of self-checking circuit
