Communication test system for vehicle control of maglev transportation

Abstract

The invention provides a communication testing system for a maglev transportation on-vehicle operation controller. The system mainly comprises a testing system host, a train diagnosis computer simulating unit, a driver operation computer simulating unit, a subarea safe computer simulating unit, an on-vehicle radio simulating unit and an on-vehicle operation control calculating result indicating unit. The testing system host generates a control command for simulating train operation and transmits a control signal to each simulating unit. The train diagnosis computer simulating unit simulates transmitted data of the train diagnosis computer to an on-vehicle operation control system in a train driving process according to the control command and generates corresponding state information, andfurthermore transmits the state information to a tested object. The on-vehicle operation control calculating result indicating unit records and displays a testing result through the storage equipment.According to the communication testing system, the testing system simulating unit is correlated with a testing object through different communication connection modes, and the communication functionof the on-vehicle operation control system can be wholly, reliably and safely tested.

Description

technical field [0001] The invention relates to the technical field of maglev rail transit, in particular to a communication test system for vehicle-mounted operation control of maglev transportation. Background technique [0002] The on-board operation control system of maglev transportation is a subsystem of the maglev train operation control system located on the vehicle. It is mainly used to control the start and stop of the train, levitation, braking and monitor the vehicle status, and ensure the safety of the train operation by monitoring the train speed curve. [0003] In order to ensure the safe operation of the maglev train, the on-board operation control system must communicate with other modules in the train operation control system (train diagnostic computer, partition safety computer, driver operation computer, on-board radio transmission system, etc.) The sent status information, command information and request information make corresponding decisions, so as to...

AI Technical Summary

Problems solved by technology

[0005] 1. The subsystems of the operation and control system of the maglev train are often developed by different developers or even different units. It is unrealistic to jointly debug the vehicle operation and control subsystem and other related modules during the development stage, and after the line is completed The joint debugging of each unit is often laborious and inefficient

[0006] 2. During the development process of the on-board operation and control system of the maglev train, it is impossible to guarantee that the function is completely correct after the development is completed. If it is directly debugged in the vehicle operation line, it may cause danger

However, in a real system, it is often impossible to conduct a sufficient and effective fault injection test, and at the same time, due to the unreasonable design of the system, there may be dangers in the test process.

[0008] 4. The communication between the on-board radio system of maglev transportation and the partition computer often adopts wireless communication, and the communication test environment is difficult and cumbersome to set up, which is often time-consuming and labor-intensive
