The elevator is a complex system involving security, elevator call board is one of the integral parts. Each lifts establish an outbound service layer board in each city, elevator outbound passengers board the elevator and the main means of interaction. By elevators call the message boards have the car and the car is currently running direction where the floor, issued by elevator outbound passengers board the elevator ride to the instruction, use the elevator call button, press the direction button upstairs, downstairs pressing direction button.江苏锐 Teng Technology Co., Ltd. based on a variety of technology development in this piece focuses on the ordinary display LED dot matrix TFT panel and lift elevator outbound call board, this one set in the key markets of the common effort to create buttons and touch key development and production. LED Elevator outbound board to LED dot matrix display information, but can also display a variety of characters through the PC, to meet customer demand for a variety of character display; TFT elevator outbound plate with true color TFT LCD screen as the display medium, display Beautiful interface, is now a clear trend developing the elevator industry. Traditional outbound elevator or black and white plate with LED dot matrix LCD display is monotonous, and the use of TFT LCD, not only high brightness and can display color images and text, display beautiful, in addition you can also show some ads based on need, information notice, is the future direction of development. Develop a TFTLCD outbound elevator controller program selected NXP's LPC2478, LPC2478 is a built-in LCD controller chip ARM7, performance excellence, it is also integrated CAN controllers, USB, Ethernet network, UART and other rich peripherals, is the best choice TFTLCD outbound control panel. Advantage elevator outbound program is very prominent: 1, the LPC2478 chip integrated LCD controller, the system is highly integrated, with no FPGA-driven LCD, the entire peripheral circuit is very simple, effective cost reduction; 2, industrial-grade chips, to make the whole system work more stable and reliable; 3, TFT true color LCD display, 24-bit interface, can support up to 1024X768 for TFT LCD screen; 4, USB port support U disk update pictures and other information is displayed, easy to operate; 5, CAN interface, but can also be set aside RS485 interface for compatibility with legacy RS485 network; 6, scalable Ethernet interface for network communication. Standard brands such as: Otis, Schindler, Mitsubishi, Foster, Hitachi, ThyssenKrupp and other brands available standard power supply stable. The main supply of Liaoning, Jilin and Heilongjiang regions. Independent production, independent design, independent research and development department. Can be used to match more than 90% in the elevator, and welcome to the concept of plant light guide
