Abstract
The utility model provides a passenger-room LED display screen which comprises a micro-control unit, a switch and a display module. The micro-control unit is connected with the switch and an address detection unit, the switch is connected with a network interface, the output end of the micro-control unit is connected with the input ends of a row driver and a column driver, and the output ends of the row driver and the column driver are connected with the display module. The passenger-room LED display screen has the advantages that the 100M network interface is used to receive and transmit display contents, thereby greatly improving the communication speed and reducing the data processing time; hardware no longer requires outer expanded FLASH, the received and transmitted contents include lattice data, and the received lattice data is directly sent to the display module and displayed by the display module, namely, what is received is what is displayed, and secondary switching is not needed; and the passenger-room LED display screen is also simple in structure, convenient to use, good in instantaneity, and high in communication speed.
Description
Technical field
The utility model belongs to public transport passenger information system field, especially relates to a kind of guest room LED display.
Background technology
In the Public Address system of the field of traffic such as light rail, subway, in each guest room, can be provided with a guest room LED display, for showing train arrival information, when having emergency condition to occur, also necessary urgent protection information can be shown, the advertising message that some are default can also be shown.The communication interface of traditional guest room LED display is RS485 interface, and master control adopts ARM7 chip, and displaying contents will be stored in FLASH to scheme sheet mode in advance, and these have all caused the technical matterss such as traffic rate is low, and real-time is poor.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of guest room LED display simple in structure, easy to use, is especially suitable for light rail, the Customer information display system of the field of traffic such as subway.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of guest room LED display, comprise micro-control unit, switch, display module, described micro-control unit is connected with address detected unit with switch respectively, described switch is connected with network interface, the output terminal of described micro-control unit drives the input end driving with row to be connected with row respectively, and described row drives the output terminal driving with row to be connected with display module respectively.
Further, described micro-control unit is STM32F207ZCT6.
Further, the chip of described switch is KSZ8863RLL.
Further, the chip that described row drives is line pipe SI4953, and the chip that row drive is 74HC595.
Further, described display module is the double-colored 8X8LED lattice module of Ф 3.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, guest room LED display has adopted 100M network interface to receive and dispatch displaying contents, greatly improved traffic rate, reduced data processing time, on hardware, no longer need to extend out FLASH, transmitting-receiving content is dot array data, and the dot array data receiving is directly delivered to display module and shown, receive and show, without secondary, change; Have simple in structurely, easy to use, real-time is good, traffic rate advantages of higher.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of guest room of the utility model LED display, comprise micro-control unit, switch, display module, described micro-control unit is connected with address detected unit with switch respectively, described switch is connected with network interface, the output terminal of described micro-control unit drives the input end driving with row to be connected with row respectively, described row drives the output terminal driving with row to be connected with display module respectively, described micro-control unit is STM32F207ZCT6, the chip of described switch is KSZ8863RLL, described line driving chip is line pipe SI4953, it is 74HC595 that row drive chip, described display module is the double-colored 8X8LED lattice module of Ф 3.
The course of work of this example: during work, switch receives from network interface the data that network transmits, send micro-control unit to, address detected unit sends signal to micro-control unit, after the data division of micro-control unit analyzing and processing oneself, signal is sent to row and drive and be listed as driving, line pipe 4953 is responsible for certain a line of gating display module, and row drive 74HC595 to be responsible for dot array data to pass out to display module, jointly complete the demonstration of display module.Guest room LED display has adopted 100M network interface to receive and dispatch displaying contents, greatly improved traffic rate, reduced data processing time, on hardware, no longer need to extend out FLASH, transmitting-receiving content is dot array data, the dot array data receiving is directly delivered to display module and is shown, institute receive be show, without secondary, change.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
