Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1-5 shown.

[0024] A synchronous control method for heavy-duty locomotive signals based on ATP / ATO equipment, which is an important part of the electrification equipment of the on-board signaling system of heavy-duty freight trains. For the equipment composition of the entire system, see figure 1 ; The whole control method includes synchronous control of train power distribution and synchronous transmission of wireless data, and the specific steps are as follows:

[0025] First, install a set of exactly the same ATP / ATO equipment for each locomotive to facilitate marshalling;

[0026] Secondly, the locomotive at one end along the running direction is used as the master locomotive of the train, which is responsible for communicating with the train control dispatching center. At the same time, the master locomotive calcul...

Abstract

The invention provides a synchronous control method for a heavy-duty locomotive signal based on ATP / ATO (Automatic Train Protection / Automatic Train Operation) equipment. The synchronous control method is characterized by comprising the following steps of: synchronously controlling the power distribution of a train, and synchronously transmitting wireless data, wherein each locomotive is provided with a set of identical ATP / ATO equipment for grouping; the locomotive at one end in running direction is used as the main control locomotive for the train and responsible for the communication with a train control dispatching center; meanwhile, the main control locomotive is used for calculating the power distribution according to the line conditions and the grouping conditions and transmitting a synchronous control command to a slave control locomotive; after receiving the command from the main control locomotive, the slave control locomotive can synchronously apply traction force or braking force; and a GSM-R (Global System for Mobile Communications for Railway) digital mobile communication network is adopted as a wireless communication synchronization link of the locomotive signal according to the control command between the main control locomotive and the slave control locomotive. By implementing the synchronous control method for the heavy-duty locomotive based on the ATP / ATO equipment, the safety and the reliability of the control system are greatly improved.

Description

technical field [0001] The present invention relates to a heavy-duty locomotive control technology, especially a train control technology composed of multiple locomotive formations using ATP-ATO equipment as the control equipment, specifically a heavy-duty locomotive based on ATP-ATO equipment Signal synchronization control method. Background technique [0002] At present, my country's Daqin heavy-duty train line is the first electrified line dedicated to heavy-duty trains in my country. It mainly operates 5000t-10000t-class coal-only trains. Its locomotive signal system relies on 450MHz / 800MHz wireless communication links for remote control. Multiple slave locomotives make these locomotives run like a whole train, thereby greatly reducing coupler force, and the air supply of each locomotive improves the braking performance. However, the use of this system also has some unsatisfactory places, such as the loss or interruption of communication data in some line sections du...
