Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a comprehensive automation simulation training system for railway marshalling yards. Background technique [0002] The marshalling station integrated automation system (SAM) has been constructed or put into use in more than ten large and medium-sized marshalling stations along the road. Since the system is a comprehensive and integrated project, it involves multiple disciplines such as information, signal, and communication, as well as multiple departments such as railway dispatching, stations, electricity, maintenance, vehicles, etc. It adopts various technologies such as computers, networks, and databases, and has various functions. , The technology is complex, requiring systematic management, operation, and maintenance units to strengthen daily training on the job, and strive to improve the level of operation and maintenance of employees. At present, the training of SAM ...

AI Technical Summary

Problems solved by technology

[0006] Yet the defect of this scheme is: 1) the above-mentioned training method is severely restricted by the environment. For example, when the system is being debugged, since the microcomputer interlocking system has usually been connected with the field equipment, the interlocking interface is all in the state of no section occupation

After simulating the open signal on the operation interface, since there will be no real locomotive running on the site, the locomotive running cannot appear on the interface

Therefore, it is impossible to simulate the continuous operation content by comparing with the actual operation method on site

2) The training method is limited in time

Since the system used for training and the production system are a set of systems, the training process must not affect the production system debugging or normal use of the production system, so the training process must fully consider the combination with the system commissioning process or normal production process; resulting in a long training cycle, The problem that the number of personnel who can be trained at a time is limited

3) Since this training method uses a real system, the operation of the system during the training process will actually bring about an impact on the field equipment; if the operating system functions when the outdoor personnel check the equipment before opening, the switch action may cause personnel safety accidents ; If the training is based on the existing production system, in the normal pick-up and dispatch operation, if there is a negligent misoperation, it may cause unexpected production accidents

[0015] The above-mentioned system can only simulate the standard station, the method is outdated, the training scene is single, and it can only train the operation function of the SAM system interface. There are mainly two defects in the following aspects:

[0016] 1. The existing simulation system cannot be consistent with the station where the user is located. The operation of the existing simulation training system can only be set according to the standard station, and the user cannot teach in the training system according to the actual station type of the station

Existing simulation systems can only be pre-fabricated by the manufacturer with specific on-site scenes when leaving the factory. If the user wants to set specific on-site equipment exceptions or station layout conditions to meet the training requirements for employees, the manufacturer needs to create the scene and then Add to the catalog of prefabricated scenes for users to read and use; this method is inefficient and the effect is not good; it is difficult to meet the diverse training requirements of users in real time

The existing simulation system can only be practiced manually on the system, and cannot use the live records of on-site operations to run the playback process on the simulation system. The function is single, and it cannot be used for the analysis of events that have occurred and the teaching of corresponding disposal measures.

[0017] 2. Defects that cannot meet the needs of production units:

In the process of communicating with users through the simulation training system, R&D personnel cannot carefully review the functions provided by the equipment, and it is difficult to obtain suggestions from users to return to the system through the training system

[0019] 2) The existing simulation environment single-set marshalling station integrated automation system uses a lot of equipment, and the cost of equipment invested in building a system is high

The equipment and configuration used by each product are similar, and cannot be mixed in one system for testing

For example: the database configuration of the system is completely consistent, if mixed, it will cause each system to be unable to distinguish its own database

As a result, only one set of system tests can be carried out in one stage of the current test environment. Before the test, specific technical personnel must import and export the equipment, which is time-consuming and laborious.

[0020] 3) The maintenance of existing simulated environment equipment is difficult and costly

Therefore, any equipment failure will affect the normal use of the simulation system

After the hardware equipment fails, it is necessary to replace the new hardware in time. Due to the influence of the equipment procurement cycle, usually the equipment failure will affect the test work in the daily simulation environment.

[0021] 4) In the process of configuring the existing simulation environment, there are many parameters that need to be modified

The problem with using this method to configure the system is that errors often occur when opening the test software, causing the test platform to fail to work normally
