Self-diagnosis system of high-voltage alarm for locomotive climbing to the top

Abstract

The invention discloses a self-diagnosis system for a locomotive top ascending high-voltage alarm. The self-diagnosis system comprises a self-diagnosis instruction key unit (1), an MCU unit (2), a signal generating unit (3), a protective filtering unit (4), a scaling-up unit (5) and a comparator unit (6). The self-diagnosis instruction key unit (1) and the MCU unit (2) are connected, the input end of the signal generating unit (3) is connected with the MCU unit (2), the output end of the signal generating unit (3) is connected with a signal connecting line 1 of a high-voltage sensor, and a signal connecting line 2 of the high-voltage sensor, the protective filtering unit (4), the scaling-up unit (5) and the comparator unit (6) are sequentially connected. The tail end of the signal connecting line 2 of the high-voltage sensor, the output end of the protective filtering unit (4), the output end of the scaling-up unit (5) and the output end of the comparator unit (6) are each provided with a lead connected with the MCU unit (2). The invention further provides a self-diagnosis method for the locomotive top ascending high-voltage alarm, and a reliable means is provided for testing the sound condition of the locomotive top ascending high-voltage alarm for an operator before locomotive top ascending.

Description

technical field [0001] The invention relates to safety auxiliary equipment for locomotive climbing operations, in particular to a self-diagnosis system for high-pressure alarms for locomotive climbing. Background technique [0002] In order to ensure the personal safety of the locomotive climbers, a locomotive climber high-voltage alarm is generally provided near the locomotive climber entrance to remind the workers of the live state of the high-voltage line on the roof. In order to ensure that the high-voltage alarm is in normal working condition, the operator needs to perform a self-diagnosis operation on the high-voltage alarm before climbing to the summit. When the high-voltage alarm fails, the existing high-voltage alarm can only give a prompt message of whether there is a failure, but cannot give which link of the high-voltage alarm system fails, which brings difficulty to the detection of technicians. Therefore, it is necessary to design a self-diagnosis system. When...
