Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a rail transit vehicle automatic station reporting dynamic simulation test method and a rail transit vehicle automatic station reporting dynamic simulation test system.
Background
The station reporting of the rail transit vehicle is generally divided into full-automatic station reporting and semi-automatic station reporting.
The full-automatic station reporting is that the vehicle-mounted ATC equipment receives a ground signal system instruction and then sends the station reporting instruction to the vehicle network control system, and the vehicle network control system sends the station reporting instruction to the broadcast control host through the MVB. The broadcast control host sends the playing information to the stop reporting execution mechanisms such as a display, a dynamic map, a broadcast controller and the like through the Ethernet, so that the automatic stop reporting action is completed.
The semi-automatic station reporting is that a starting point position is set for a vehicle firstly, then the actual running speed provided by a speed sensor on the vehicle is obtained by a vehicle network control system and sent to a broadcast control host, or the broadcast control host directly obtains a speed signal of a GPS antenna, and then the actual running position of the vehicle is obtained through integral operation. And the broadcast control host compares the position data with the kilometers stored in the broadcast control host in advance, and sends the playing information to a station reporting execution mechanism such as a display, a dynamic map, a broadcast controller and the like through the Ethernet when the condition that the vehicle enters or exits the station is judged to be met, so that semi-automatic station reporting action is executed.
The automatic stop reporting function of the vehicle affects the safety and comfort of passengers, so the automatic stop reporting function must be tested, and the vehicle can be put into formal operation.
Existing automated stop-reporting tests are typically performed by: applying for all lines of the formal operation of the vehicle, and operating the vehicle in a full-automatic mode and a semi-automatic mode respectively. And in the running process, the behavior of the station reporting equipment of each compartment of the vehicle is observed and recorded one by a tester. This test method has the following drawbacks:
1) and under the condition that the ground signal system is not debugged, the full-automatic station reporting function test cannot be carried out.
2) The test cost is high, and vehicle resources, line resources, signal resources, high-voltage power supply resources, manual resources such as drivers and dispatching and the like need to be prepared in advance in each test.
3) The line formally operated by the owner often has various task requirements such as operation, maintenance and the like, the resources are precious and the application procedure is complex. The conventional test method also has the risks that the test result is unqualified, and the vehicle is rectified and retested. Therefore, the test period is long due to the influence of line resources and the number of tests.
4) The number of the station reporting devices of a train is large, but the actual station reporting action of each station is short in duration, and the influence of human factors cannot be avoided by adopting a mode that a tester observes the phenomenon and judges the result.
