Elevator Control System Based On AT94K40

With the development of national economy and the improvement of people's life, a lot of the elevators that installed before 1990 year require to be reinstalled because of the laggard control system high frequency of fault inconvenient maintenance high power cost sometimes not comfort and so on. For the quantity is enormous the elevator will become the focus of purchasing in the follow years. With the improvement of the living standards of the people and individualized design of living conditions, the villa use small-scale elevator will be developed rapidly soon.For the reason above, the elevator control system is a very popular direction. Now a lot of foreign big company's elevator control systems have taken a great part in the Chinese market. We are passive to maintain the elevators. Also as the development of the Chinese electronic technique it is a good time to make a Chinese elevator.The elevator control system adopt FPSLIC SOC (System On Chip) AT94K40 microcontroller of ATMEL as the main controller. AT94K40 is composed of AVR microprocessor and FPGA. It has the multifunction of the traditional microprocessor and the fast data processing speed. Adopt this kind of SOC chip the controller's digital logical circuit makes up the controller's speed and dependability is much better compared with the traditional microcontroller. Have solved the system halted of the microcontroller and the flying of the program from essence. The data communication between the main controller car controller and outside call controller is by CAN bus protocol. CAN bus communication, use the on-the-spot bus of industry to...
