Embodiment Construction

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] Such as image 3 As shown, a new type of dynamic map display system includes LCD dynamic map master control, LCD display, train Ethernet and train RS485 bus network, and the left and right sides of the car body are composed of two LCD dynamic map masters. Video control pair, the control pair is set in each passenger compartment respectively, each LCD dynamic map master in the control pair is connected to the train PA master through the RS485 bus and receives the train control information issued by it, the control The left and right LCD dynamic map master controllers in the pair are respectively connected to the corresponding first LCD display screens on the left and right sides of the passenger room through the differential signal output ports. There are multiple LCD displays symmetrically on the left and right sides of the pa...

Abstract

The invention relates to a novel dynamic map display system. The system comprises liquid crystal display (LCD) dynamic map master controls, LCD screens, a train Ethernet and a train RS 485 bus network. The two LCD dynamic map master controls form a left and right dynamic map video control pair of a carriage train body, the control pair is arranged in each passenger carriage, and each LCD dynamic map master control in the control pairs is connected with a PA master control through a RS 485 bus and receives train control information released by the PA master control. The left and right LCD dynamic map master controls are connected with corresponding first LCD screens on the left and right sides in the passenger rooms through differential signal output ports respectively, a plurality of LCD screens are arranged on the left and right sides of the passenger rooms symmetrically respectively, and the LCD screens on each side are connected in a cascading mode. By means of the system, centralized control of the passenger rooms is achieved through a distributive central control scheme, normal display of other carriage dynamic maps cannot be affected by the failure of one passenger room, and the system cost is reduced effectively.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted broadcasting systems for rail transit, and in particular relates to a novel dynamic map display system. Background technique [0002] Rail transit not only has the attribute of transportation, but also has the attribute of city business card and media publicity. The traditional LED dynamic map has the disadvantages of single display information, poor scalability, and inability to realize cross-line operation, etc., which can no longer meet the needs of the current rail transit operation mode. The LCD dynamic map display system can achieve high resolution, digital information transmission, multi-interface and multi-information display, allowing passengers to maintain information exchange with the outside world at all times in a closed space, fully reflecting the people-oriented and passenger-oriented public transportation Service philosophy. The system can realize the management and release of mult...
