Abstract
The utility model provides a CR200J motor train unit safety loop test device, and discloses a detection circuit design formed by a wireless communication mechanism of a communication seat plug and a hand-held detection control end, so that the detection operation is flexible and efficient, communication can be performed by using a wireless transceiver module according to the requirements of maintenance personnel and field test, and the safety loop test device is convenient to use. According to the method, the action state of a certain safety loop is controlled and checked, the detection efficiency is high, detection can be completed only by a single person, efficient and accurate detection of the safety loop of the motor train unit is achieved, the problem that the safety loop of a single carriage cannot be tested and checked after the safety loop of the CR200J motor train unit is decompiled and separated is solved, and the detection efficiency is improved. Maintenance personnel can find and deal with the fault problem of the safety loop in advance, and it is ensured that the safety loop of each compartment is in a good state after being overhauled and the system test is normal after marshalling. Meanwhile, the utility model provides a simple, reliable and safe test method for solving the problem that the test cannot be carried out due to the limitation of maintenance conditions during the separation maintenance of the cut-through loop.
