Thesis Topic:Design And Implementation Of Elevator Control System Based On Stc12C5a60S2

Since the reform and opening up, China’s economic development and rapid growth throughout the city, urbanization will greatly speed up the. With row upon row of tall buildings around the country quickly built up, the elevatordemand is also rapidly increasing. Demand for the goods ladder city someeconomically developed regions also has a gradually increasing trend. In addition, with the broad masses of the people’s living standards improve,residential, villas and other small elevator is booming. All of theseapplications, so that the elevator has a very large market.Present situation of high performance elevator on the current market is dominated by foreign elevator company monopoly based on, in order toenter the market as soon as possible, to realize industrialization, this paperaccording to the actual demand of project, for the elevator market at present,design a low cost, low power consumption, high price of elevator controlsystem is safe and reliable and convenient for the old elevator update.The elevator control system of this thesis intends to use STC12C5A60S2single-chip microprocessor as the core of the system control chip, and supplemented by relevant peripheral circuits, such as CAN bus circuit, CPLD circuit as the elevator control system components communication processingmethod and system I/O port expansion mode. Adopting these methods for the transformation of the old elevator controlsystems of the past provides a more convenient condition, to seek greater development space for the elevator enterprises.This paper mainly does the following work:(1) This paper based on the practical research of elevator control system,introduced the elevator control system in the domestic and foreign research present situation and the development trend, and in the light of the actualneeds of elevator control system to make the overall scheme of the system isdesigned, and the definition of the interface design function. Innovative ideasof this part lies in the overall design of elevator control system divided intodifferent functional parts, so as to realize the design of more specific. (2) The hardware circuit of the elevator control system was designed, including the design of the bus member and a communication circuit elevator master control board and the user calling control board and the design of control system. Innovative ideas for this part of the work is to design the hardware circuit of the system, using modular design, more convenient for the readers to understand the.(3) The driver of the bus elevator control system circuit was designed to write,and write a CPLD program was developed, man-machine interactive operation procedures, elevator control system design of control programcompilation. Innovative ideas for this part of the work is on the system when the program design and the hardware circuit was effective combination,convenient for future system program debugging.(4) The system described in the elevator control system related test methods on the test platform as well as the results of the verification system, the designof elevator control system superiority and reliability. Innovative ideas of this part lies in the elevator control system implements the test, in order to prove the results of the work.(5) The dissertation is a summary of the work and the prospect for the future.
