Embodiment 1
[0034] Such as figure 1 As shown, the present embodiment provides a train information display system, including a central processing unit, a control operation display screen, a positioning unit, an antenna, an MVB unit, a main switch, a sub-switch, a compartment sub-processing unit, an in-vehicle display, and an external display ; The positioning unit, the MVB unit, the control operation display screen and the main switch are respectively connected to the central processing unit; the sub-switches are connected to the main switch through Ethernet; The compartment sub-processing unit is connected to the sub-switch; the antenna is connected to the positioning unit; when the positioning unit loses data, the central processing unit starts the mileage redundancy positioning algorithm, and the train provided by the MVB unit Operational data, combined with the train operating route database, to calculate real-time mileage information for positioning. Through accurate positioning info...
Embodiment 2
[0046] Such as figure 2 As shown, this example provides a train information display method for realizing the train information display system of Embodiment 1, comprising the following steps:
[0047] Step S1, the system is powered on and initialized, and the train operation database and train information database are automatically loaded:
[0048] As described in step S1, when the system is powered on and starts running, the train operation database and display information database are automatically loaded. A train display information list is displayed on the first man-machine interface, and at the same time, the system automatically detects the online status of the equipment, which is also displayed on the first man-machine interface. The train display information is information in a train display information database.
[0049] Step S2, waiting for parameter setting, setting the train number information and marshalling information of the train;
[0050] As described in st...

Abstract
The invention provides a train information displaying system and method. The train information displaying system comprises a central processing unit, a control operation display screen, a positioning unit, an antenna, an MVB (Multifunction Vehicle Bus) unit, a main switch, a branch switch, a carriage branch processing unit, a train internal displayer and a train external displayer, wherein the positioning unit, the MVB unit, the control operation display screen and the main switch are respectively connected with the central processing unit; the branch switch is connected with the main switch through Ethernet; the train internal displayer and the train external displayer are respectively connected with the branch switch through the carriage branch processing unit; and the antenna is connected with the positioning unit. When data of the positioning unit are lost, a mileage redundancy positioning algorithm is started through the central processing unit, train operating data are provided through the MVB unit and a train operation route database is combined so as to work out real-time mileage information and realize the positioning. The system provided by the invention has the advantages that trains can be accurately positioned; the data are transmitted at a high speed; and the information is intelligently displayed.
Description
technical field [0001] The invention relates to the field of train information display, in particular to a train information display system and method. Background technique [0002] With the rapid development of economy and information technology, high speed, intelligence and comfort have become the trend of train development. At the same time, passengers have also put forward higher requirements for train comfort and information services. The train information display system is one of the main ways to realize train service informatization. At present, information display devices are gradually installed on domestic high-speed trains. [0003] This type of information display device generally adopts 485 bus, which has the problems of slow data transmission, low reliability and poor scalability in the complex working environment of the train. [0004] The triggering of information display content is generally triggered by manual display, which is prone to omission and misre...
