Problems solved by technology

In the case where the traction power supply arm on both sides of the traction substation is used as a unit to form a traction power supply integrated automation system, for the AT power supply mode, due to the complex structure of the system, it is difficult to realize it by a single ranging device, and the communication signal of the power supply integrated automation system It often interferes with the ranging system, which greatly reduces the accuracy of data collection and data processing, and it is difficult to realize synchronous signal transmission, data collection and data transmission between points and points, and between places.

Embodiment 1

[0021] Embodiment 1: a kind of communication method of old standard system, it is characterized in that it comprises the following steps:

[0022] ① When a fault occurs at a certain point of the traction network, the measurement and control device installed on the protection side of the electric railway feeder detects the fault and sends a signal to start the fault;

[0023] ② After receiving the above fault signal, the fault marking system judges whether the starting signal is the left power supply arm or the right power supply arm;

[0024] ③Send a general call frame to all faulty devices on the faulty line in the power supply arm on this side through the communication network;

[0025] ④When the faulty devices of the substations, AT stations, and partition stations on the power supply arm receive the call frame sent in step ③, they take out the data that conforms to the time stamp information from the memory, calculate the effective value, and upload it to the Substation s...

Abstract

A communication method for a fault system: ①The measurement and control device detects a fault and sends a signal to start a fault; ②The fault system judges the activation signal after receiving the above fault signal; ③Sends a general call frame; ④From the memory Take out the data that conforms to the time scale information; ⑤ send the calculation results, and upload to the local monitoring and dispatching master station; the fault marking system, including the external power grid, power supply arm, and electric railway feeder, is characterized in that the fault marking system is also controlled by GPS satellites It is composed of a clock, a channel, a marking device and a communication processing device; its advantages are: simple operation, high acquisition accuracy, and synchronous transmission of data.

Description

(1) Technical field: [0001] The present invention relates to a communication method and its application, in particular to a communication method and its application of a faulty system. (two) background technology: [0002] The AT fault location system is suitable for fault point calibration of all short-circuit fault types in various operating modes under the condition of AT traction power supply system. In the case where the traction power supply arm on both sides of the traction substation is used as a unit to form a comprehensive automation system for traction power supply, for the AT power supply mode, due to the complex structure of the system, it is difficult to realize it by a single ranging device, and the communication signal of the power supply comprehensive automation system It often interferes with the ranging system, greatly reducing the accuracy of data collection and data processing, and it is difficult to realize synchronous signal transmission, data collecti...
