TEST APPARATUS OF INTERLOCKING DETECTION SYSTEM, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/240477

A1

A test apparatus of an interlocking detection system, and an electronic device. The apparatus comprises: a first controlled end of a first relay, a second controlled end of a fourth relay, and one end of a resistor are connected to one end of an interlocking loop, a third controlled end of the first relay is connected to a first controlled end of a third relay, and a first control end of the first relay receives a first signal; a first controlled end of a second relay is connected to the other end of the interlocking loop, a second controlled end of the second relay is connected to a first controlled end of the fourth relay, and a first control end of the second relay receives a second signal; a second controlled end of the third relay is connected to a power supply, a third controlled end of the third relay is grounded, and a first control end of the third relay receives a third signal; a third controlled end of the fourth relay is connected to the other end of the resistor, a first control end of the fourth relay receives a fourth signal, and second control ends of all the relays are grounded; and then the state of the interlocking loop is simulated by means of the first signal, the second signal, the third signal, and the fourth signal, so that the detection efficiency and accuracy are improved.
