The operation method of the screen display of the train operation monitoring device without basic data storage

Abstract

Disclosed is an operation method of a screen displayer of a train operation monitoring device without stored basic data. A main control unit adopts a linear FLASH as storage medium of basic data and sends the basic data needed by the screen displayer in real time according to the operation state of a train; the main control unit broadcasts the basic information of two block sections in the front operating direction of the train in real time; when positioning of the basic data begins and the route of the train is transferred, the main control unit actively sends the basic data in the front operating direction of the train to the screen displayer; the screen displayer judges whether the basic information, broadcasted in real time, of the two block sections in the front operating direction of the train is consistent with the received basic data in the front operating direction of the train; if not, or the screen displayer is restarted due to power down, the screen displayer actively applies for basic data from the main control unit; after the main control unit receives the application, the main control unit immediately sends the basic data in the front operating direction of the train to the screen displayer from the current position; the screen displayer displays various types of state information in the front operating direction of the train according to the received basic data.

Description

technical field [0001] The invention relates to a kind of basic data applied in the train operation monitoring device (hereinafter referred to as LKJ). Background technique [0002] The basic data of the train operation monitoring device (hereinafter referred to as LKJ) is the basis for the realization of the control function of the LKJ and the basis for operation analysis. The accuracy of the basic data of the LKJ is the premise and guarantee for monitoring the safe operation of the train. Currently, the basic data of the LKJ (vehicle part) are stored separately In the LKJ monitoring host and LKJ screen display. [0003] The LKJ screen display displays the information of the signal machine ahead of the train in real time according to the stored basic data, and displays the line curves, slopes, crossings, bridges and tunnels within no less than 3km ahead of the train in the form of curves, symbols and text And information such as station, signal machine, catenary phase mark...

AI Technical Summary

Problems solved by technology

[0008] 2) There are certain security risks

[0009] ①. When the basic data is replaced, if any data is not updated or the updated version is wrong, it will affect the normal operation of the train;

[0010] ②. The screen display needs to store LKJ basic data, and there are certain risks in the effectiveness of data storage;

[0011] ③ When the data is updated correctly, if there is a momentary abnormality on a certain display, the display at this end will not be able to correctly call the basic data, thus affecting the normal operation of the train

[0012] 3) Poor adaptability of the screen display

[0013] When a fault occurs when the train is running to another railway bureau and the screen display needs to be replaced, the screen display of another railway bureau cannot be replaced due to the different basic data stored in the internal storage (or the replacement is very complicated and the data needs to be reset)

[0014] 4) The processing logic of the screen display software is complex and poorly adaptable

[0015] The LKJ basic data call and processing logic is relatively complicated, and the software needs to consume more resources to process the basic data, and when the basic data format changes, the screen display software needs to be modified and replaced at the same time; if the screen display software and the LKJ monitoring host software process data When there is a difference in the method, it will cause inconsistencies in the display and control of the screen display
