Problems solved by technology

Since there are many types of connectors used for overhauling passenger car axle temperature and broadcasting networking tests, including broadcasting connector plugs, 15-pin communication connector plugs, DC600V-39-pin communication connector plugs, and AC380V-39-pin communication connector plugs, different communication connections are used. It is impossible to carry out the test on the passenger car with the device, which greatly increases the difficulty of passenger car maintenance and reduces the maintenance efficiency

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] 1. Shaft temperature networking test

[0015] 1) Car number renumber test: select the same communication connector plug as the bus under test, and insert it into the socket of the bus under test. Turn on Q1, turn off Q2, set the axle temperature alarm of the bus under test and the axle temperature alarm of the test device to the same serial number, turn off the axle temperature alarm of the bus under test, and then turn on the bus again, and the axle temperature alarm of the bus under test will flash The car order number is successful.

[0016] 2) On-line alarm test: set the sequence number of the bus under test to be different from that of the test device, and use the temperature control device to control the ambient temperature change of the axle temperature sensor RT1, so that the axle temperature alarm of the test device is in the...

Abstract

The invention belongs to the field of passenger car maintenance, and especially relates to a passenger car networking test device. The passenger car networking test device comprises a rectification and voltage-stabilizing power supply, an axle temperature alarm apparatus, an axle temperature recorder, a connector plug, a cage-type terminal strip, a temperature control device, an acousto-optic indicating device and a power amplifier. The passenger car networking test device is in rapid connection with a tested passenger car through the passenger car communication connector plug, the alarm temperature of the axle temperature alarm apparatus is precisely controlled through the temperature control device, an axle temperature networking alarm function is realized, and whether the axle temperature networking function of the tested passenger car is normal is judged. The passenger car networking test device adopts the power amplifier to send audio information to the tested passenger car, the networking with the tested passenger car is realized through a broadcasting network, and whether the broadcasting networking function of the tested passenger car is normal is judged according to the definition of the audio information received by a loudspeaker of the tested passenger car, so that the difficulty of the passenger car maintenance and organization is reduced greatly and the maintenance efficiency is improved.

Description

technical field [0001] The invention belongs to the field of passenger car maintenance, and in particular relates to a passenger car networking test device. Background technique [0002] On July 31, 2015, the new plant repair regulations of China Railway General Corporation came out. The regulations require that a network test should be done before leaving the factory for passenger car maintenance to ensure that the factory car is in good condition. Since there are many types of connectors used for overhauling passenger car axle temperature and broadcasting networking tests, including broadcasting connector plugs, 15-pin communication connector plugs, DC600V-39-pin communication connector plugs, and AC380V-39-pin communication connector plugs, different communication connections are used. The passenger car with the device cannot be tested, which greatly increases the difficulty of passenger car maintenance and reduces the maintenance efficiency. Contents of the invention ...
