With the increasingly prominent urban traffic congestion problem, various public transportation solutions are proposed, including subways, BRTs, light rails, smart rails, and the like, and especially intelligent vehicles with higher automation and intelligence degrees. The intelligent rail train is a brand new transportation tool developed by institute of electric locomotives, ltd, zhou zhi. The maximum speed per hour is designed to be 70 kilometers, high-speed rail flexible marshalling is adopted, the virtual track following control technology is utilized to run on a set virtual track, the zero emission and pollution-free characteristics of rail trains such as light rails and subways are achieved, and multiple power supply modes are supported. The intelligent rail train is used as the intelligent rail express transportation system of the core carrier, has the advantages of short construction period, low infrastructure investment, high urban adaptability, strong comprehensive transportation capacity and the like, and has good application prospect.
The intelligent rail train is particularly different from the technical difference of the traditional rail vehicles such as subways, and firstly, the intelligent rail train runs on the ground and is in a mixed running state with other vehicles on the ground; secondly, compared with the subway, the operation path of the intelligent rail train has no uniqueness, and the operation scene also has no uniqueness; and thirdly, the operation of the intelligent rail train on multiple lines is adjustable at any time, and the operation of the intelligent rail train on different lines can be adjusted according to actual needs.
The schedule plan information comprises information such as train number, running direction, departure time, stop time, arrival time, running path, turn-back time and the like, is compiled and dispatched by a dispatching management system and is sent to a vehicle-mounted computer at a certain time so as to guide the running of intelligent transportation tools (such as intelligent rail trains). Taking the intelligent rail train as an example, due to the characteristics of the intelligent rail train, the running path of the intelligent rail train is not fixed, and the intelligent rail train can support the mixed running line of the train and the operation of a multi-line scene. Therefore, the intelligent rail train needs to match corresponding line data in real time according to the received schedule plan information, and the vehicle-mounted computer of the intelligent rail train can enter a normal mode after entering a main line; during the period, the vehicle-mounted computer of the intelligent rail train displays the running path of the electronic display screen in the train and plays the broadcast information content in the train according to the received schedule information.
From the above, it is very important to correctly transmit and receive schedule plan information, especially for intelligent public transportation. In the technical field of traditional rail transit such as subways and trains, some practitioners have proposed some technical schemes for compiling or issuing schedules, such as the chinese patent application "a synchronization method of schedule files of a subway ATS system" (CN201911079678.2), the chinese patent application "a method and a system for ensuring accurate operation of subway trains according to schedules" (CN201410492745.4), the chinese patent application "a method and a device for downloading and controlling train operation plans" (CN201811284073.2), and the like. The traditional modes are mainly applied to the field with stronger regularity and uniqueness in train operation and have powerful communication guarantee. However, none of the technical solutions applied to the conventional rail transit considers the operation characteristics of the smart rail train, and how to handle the situation that the train is not in communication with the dispatching center is not proposed.
