Embodiment
LED display character library type control system principle of the present utility model as shown in Figure 1, comprise PC, character library type control card and LED display, PC turns the RS232/RS485 interface that 485 converters connect character library type control card by RS232 connection or passive RS232, and character library type control card connects LED display.RS485 is 2 line differential transfer.Possess transmission range long (1KM), anti-interference good characteristics, cheap, the LED on-screen data that is widely used in stopping transmission.General desktop computer is not to be with the RS485 interface, but the RS232 serial ports is arranged, can use＜passive RS232 turns 485〉converter, realize conversion.If computer does not have the RS232 serial ports, just can use USB RS 232 mouth.
The whole RAM of character library type control card refresh in real time, and configuration testing software and communication protocol are provided.Address code can arrange by the RS485/RS232 mode, supports the user can revise the start literal and shows (the longest 128 Chinese characters).This character library type control card comprises following characteristics: (1) RS485/RS232 interface is optional.The RS485 mode can be supported maximum 255 display screens networkings.(2) built-in 16/32 GB2312 Chinese character base and English character library.(3) monochrome: 512 * 32 is double-colored: 256 * 64.(4) queuing control card scan mode: 1/16,1/8,1/4, have 2 general HUB08 output interfaces.(5) sweep frequency: 100HZ.(6) maximum information length: 256 Chinese characters or 512 ascii characters.(7) display mode: directly show/move to left/glimmer/on move, speed is adjustable.(8) start literal: support the user can revise the start literal and show (the longest 128 Chinese characters).(9) dynamic display text adopts the RAM storer, and all RAM refresh in real time, without FLASH erasing and writing life problem.(10) provide configuration testing software and communication protocol.(11) MAX232 and the MAX3485EAS of communication chip employing are technical grade, guarantee communication robust.The built-in simplified form of Chinese Character character library of this character library type control card directly sends the ASC code by serial ports and just can show, has a transmission of data few, the advantage of fast response time.Be fit to very much adopt intelligentized control system, can reduce the person of inducing, reduce cost, raise the efficiency.Reduce the program development difficulty, shorten the construction cycle, system stability is provided.
Embodiment 1, and along with economic development, city high rise building stands in great numbers, and the underground parking is more and more.The underground parking, the number of plies is many, and area is large, and environment is dark moist, atmosphere draught-free, working environment very severe.Adopt the artificial induction to stop, cost is high, and is dangerous.When car was many, workload was very large.So at large parking lot, be fit to very much adopt intelligentized parking lot inducible system, can reduce the person of inducing, reduce cost, raise the efficiency.Use the utility model LED display character library type control system the parking lot inducible system workflow as shown in Figure 2, principle is as shown in Figure 3.Guiding LED screen has played crucial indicative function in whole process of inducing, allow the driver can accurately find fast the position of parking stall.
Master control PC connects the card sender card reader, door lock, LED screen, monitoring camera.When automobile is entered, the button card taking, master control PC records automobile information, and retrieves the position, parking stall, calculates traffic route, generates induction information.Master control PC sends out induction information to go specific LED guiding screen, indication driver driving direction.The LED screen that leads receives the information from PC, and shows.Use character library type LED control card, be conducive to reduce the program development difficulty, shorten the construction cycle, system stability is provided.
