Abstract

The invention relates to a method for realizing ZPW-2000 track circuit calibration intellectualization, which is realized through an intelligent calibration system. The intelligent calibration system comprises a control terminal and an execution end, a control unit is in communication connection with the control terminal through a Bluetooth module, the output end of the control unit is connected with the input end of a transmitter through a relay matrix unit. The output end of the transmitter is connected with the wire inlet end of the reversing unit, the wire outlet end of the reversing unit is connected with the input end of the attenuator through a track to be calibrated, the output end of the attenuator is connected with the input end of the receiver, and the output end of the receiver is connected with the input end of the control unit through the relay matrix unit. According to the method for realizing the intelligent calibration of the ZPW-2000 track circuit, by applying the intelligent calibration system, the automatic selection of the calibration standard of the track circuit, the automatic terminal connection according to the calibration standard and the judgment and recording of the calibration result can be automatically completed, and the intelligentization and automation of the calibration of the track circuit are realized.

Description

technical field [0001] The invention relates to the technical field of realizing rail transit power distribution, in particular to a method for realizing the intelligentization of ZPW-2000 rail circuit standard adjustment. Background technique [0002] PW-2000 track circuit is the mainstream equipment of my country's railway signal, through which track occupancy monitoring, track signal transmission, etc. can be realized, so as to ensure the safe operation of trains. Before the new line is opened or when the existing line is transformed, the track circuit needs to be adjusted to ensure that the track signal meets the relevant technical requirements. [0003] At present, there are a large number of manual operations in the entire track circuit calibration process, such as manual calculation of cable length, manual confirmation of cable compensation standards, manual search and connection of compensation network terminal numbers, manual review and selection of adjustment table...

AI Technical Summary

Problems solved by technology

The entire standard adjustment process requires a lot of manual measurement, manual calculation, manual table lookup, and manual connection. On the one hand, it causes low work efficiency, affects the progress of the project, and affects railway transportation in severe cases.

On the other hand, a large number of manual operations can easily cause human errors, affect the quality of track circuit calibration, and even cause damage to track circuit equipment or personal injury. Specifically, there are the following outstanding problems:

[0004] 1) The selection of standard adjustment standards is cumbersome, and all of them are manually operated, so it is very easy to make mistakes in the selection of adjustment standards, resulting in misadjustment and misadjustment;

[0005] 2) During the calibration process, manual operation is required for terminal connection, which is heavy workload, low efficiency, and error-prone;

[0006] 3) The calibration results are recorded manually, which increases the workload of personnel, and the recorded results are unreliable
