Elevator Control System Fault Diagnosis And Elevator Simulation System

With the development of the modern city, the requirement of elevator is becoming more and more. Imploring the safety and decreasing test on spot is the technology direction of elevator control. Following the application of microcomputer in elevator control system, test process is becoming more and more complex, so the capacity of test personnel and method of test must be enhanced. The situation demands that only advance test device be equipped, the quality of products and work efficiency can be improved.According to this situation, using industry control computer, data acquisition board, combining computer software, we designed and developed a fault test system for lift controller. This system has realized automatization in some degree. Being compatible, this system can be applied to various lift controllersThe paper analysis the important application of data acquisition system (ADS) in the fault test system for lift controller, introduces concept ^ significance and function of ADS, describes the typical structure of ADS.We designed the hardware of test system in the paper, analyzed the principle of each parts of hardware and the design of microcomputer interface circuit.We designed the software of test system in the paper; discussed the scheme of software and the application of Visual Basic in real-time test system; introduced the digital filter, data compress, parameter transform, curve painting and so on.At last we applied the Expert System theory of artificial intelligence to lift's controller fault test system, analyzed the application of Expert System in auto-test field, and designed the Expert System of fault test for lift's controller, and introduced a method of machine learning in this system on emphases.This system has been applied to Ltd. ZheJiang JuRen elevator, the practical running results show that the system is practicable and convenient, and improved the test efficiency.
