Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0021] like figure 1 As shown, a method for automatic analysis of code loss of track circuit in a station includes the following steps:

[0022] Step 1) Use the signal acquisition equipment to collect the pick-up and drop states of the departure code sending relay, pick-up code sending relay, transfer relay and track relay in real time. The signal collection equipment adopts the signal centralized monitoring system that comes with the original system. The monitoring system can collect the pick-up and drop-off states of each relay.

[0023] Step 2) According to the working principle of the electric coding circuit, calculate the code sending timing of the electric code sending current. This process depends on the computer. When the transfer relay of this track circuit is sucked up, it will pre-code this track circuit by one track circuit ...

Abstract

The invention provides an automatic analysis method for code decoding and code dropping of an in-station track circuit. The method comprises the following steps that 1) states of a departure code sending relay, a receiving code sending relay, a transmission relay and a track relay are collected in real time through signal collection equipment; step 2) according to the working principle of a coded circuit, calculating the code sending time of coded sending current; 3) analyzing the current change in the code sending time period; according to the method, the problem of code falling positioning caused by ground equipment faults is solved, and the blank that the code falling position cannot be determined in the traditional code falling analysis process is filled up.

Description

technical field [0001] The invention relates to the field of maintenance of track circuit coding equipment in a station, and in particular relates to an automatic analysis method for code dropping of a track circuit in a station. Background technique [0002] The track circuit coding equipment in the station can upload the occupation information and ground signal status of the track circuit in the station to the on-board equipment of the train through the rails. Conforms to the safety principle of "failure-oriented safety". [0003] In field use, it often happens that the vehicle equipment cannot receive the data information of the ground equipment correctly due to the failure of the ground equipment or the vehicle equipment, which is commonly known as "dropping codes". [0004] When "dropping codes" occurs, it is necessary to find the cause and location of the fault in time, and the current centralized signal monitoring system cannot solve the problem of distinguishing gro...
