The invention provides a full digital compartment dynamic map. The full digital compartment dynamic map comprises a control board, a power supply board, an interface board, an address board and a display board, wherein the power supply output interface of the interface board is connected with the input interface of the power supply board; the output interface of the power supply board is respectively connected with the power supply interface of the display board, the power supply interface of the control board and the power supply interface of the address board; the display interface of the control board is connected with the input interface of the display board; the interface of the address board is connected with the address interface of the control board; the network interface of the control board is connected with the interface of the interface board. The full digital compartment dynamic map has the benefits that the control board transmits received control signals of the interface board and received address signals of the address board to the display board for display, the display screen displays the current running position of a train and information on the next station where the train is to reach, the control board is connected with the interface board via the network interface, the communication ratio is improved, and the time of data processing is shortened; in addition, the full digital compartment dynamic map has the advantages of simple structure, convenience for use, strong commonality and practicality, high reliability and the like.
Description
technical field [0001] The invention belongs to the field of public transport passenger information systems, and in particular relates to a dynamic map of full digital passenger compartments. Background technique [0002] In the passenger information display system in light rail, subway and other transportation fields, there will be a dynamic map of the passenger compartment above the door of each passenger compartment, which is used to display the current location of the train and the next station the train will arrive at; it can also display the The running line and running direction. In the existing technology, the dynamic map of the passenger room is not fully digital, and there are technical problems such as poor versatility and low reliability. Contents of the invention [0003] The problem to be solved by the present invention is to provide a dynamic all-digital passenger room map with simple structure and convenient use, which is especially suitable for use in pas...
