Research On Automation Control And Failure Diagnosis Of Elevator By Pcc

Elevators have already become the essential vertical transportation in people normally life, with the development of economy and the booming of high buildings. In order to preferably satisfy custom's requirement, the major object of elevator Produce Corporation of our country and foreign is the development elevator of more safety, more reliability, more efficiency, less energy consumption and riding more comfortable. And then it is the most important way that we can come to the above target by developing elevator control system.The fast development of industry automation technology provided the substance foundation for the technical renewing of elevator control system. The most important and effective means is that we constantly induct the most advanced technique and produce of industry control field into elevator control. PCC(Program Computer Controller) ?the new-type industry control facility, which integrated together with computer, communication and automation technology, is applied to elevator control in this research.The research submits that elevator major control system adopts B&R 2005 PCC, based on the full analysis of our country's percent situation and development tendency of elevator, and designs a twelve landing central selection control elevator's hardware and software of control system. By making use of the function of logical operation and date processing of PCC, the elevator PCC control system has the capacity of monitoring and diagnosing failure of elevator operation. Moreover the research introduces the elevator group control and that PCC control system is applied to remote monitoring of elevator.The research analyzes the development status of elevator industry and the elevator marketplace situation of our country, and the economic benefit of PCC elevator control system. The issue manifests that PCC elevator control system have the better economic benefit, and the achievements of the research are worthy to be generalized and applied.
