Embodiment 1

[0080] In the first embodiment, a new communication protocol is used to transmit control messages between the locomotive and the ground control center. Due to the large amount of information transmitted, effective safety control of the locomotive can be realized and the safety of the locomotive can be improved.

[0081] While improving the safety of the locomotive, automatic driving (ATO) messages can also be added to enable the locomotive to have a certain intelligent driving function, thereby realizing the operability of the locomotive. The ATO message is generated by the ground control center when generating the ATP message, and sent together with the ATP message. The ATO message includes driving command, schedule data, acceleration data, and return data, as shown in Figure 3. The process of generating the ATO message is described in detail below.

[0082] The ground control center generates acceleration data according to energy consumption data and mode correction data, g...

Abstract

The invention discloses a locomotive control method and a locomotive control system, and the method comprises the following steps: a ground control center generates and sends an ATP message which contains protective point distance data, road speed restriction data, advanced road selection data and an emergence command; a locomotive-mounted control device receives the ATP message and determines whether the emergence command is valid, and controls the locomotive to stop if valid, determines the validness of the advanced road selection data if invalid; if the advanced road selection data is valid, the locomotive-mounted control device selects a driving path by using the advanced road selection data to implement the path selection algorithm, and generates first speed data according to the selected driving path and the protective point distance data; if the advanced road selection data is invalid, the locomotive-mounted control device generates the first speed data according to the current driving path and the protective point distance data; the first speed data is compared with the predefined road speed restriction data, and the smaller speed data is taken as the current driving speed data, and then the invention controls the locomotive according to the driving speed data. The method and the system of the invention can control the safe and intelligent driving of the locomotive.

Description

technical field [0001] The invention relates to the technical field of locomotive control, in particular to a locomotive control method and a locomotive control system. Background technique [0002] In the process of rapid development of the transportation industry, the development of locomotives is the fastest, from railway locomotives to subways and urban railways. [0003] At present, the control of the locomotive adopts the relay coding method, that is, multiple safety relays are used, and the binary logic data of the relays are combined to obtain a variety of information to express the meaning of the target speed and the current speed. This relay then drives the relevant track circuit to send the current of the corresponding frequency to the track for the locomotive to collect. Each frequency represents information of a speed class, and the locomotive uses this information as the basis for driving. [0004] With the development of locomotives, the application of digit...
