Abstract
The elevator is a kind of product with comprehensive more complicated machine electricity, elevator the technical development and modern science is vitally related.Gather to choose the control elevator in various category of the elevator since can carry out the driver operation and can also carry out to have no driver operation, is a kind of elevator that moves a control highly.In gather choose the control elevator, this article is concerning three soon elevator of the design of the PLC electricity control system.
Communicate double soon elevator of the electricity control system mainly adopted a programmable controller PLC technique.The PLC technique is use many electronicses of the microprocessor realization is machines after the electricity and in fixed time with count a machine of combination body, the trapezoid diagram type plait distance of[with] the adoption electricity operation personnel's habit, keep a view to understand easily.
Because the direct current motive depends to change toward machine to change to, cause the direct current motive manufacturing cost high,the price is expensive and support trouble and use environment to be subjected to restriction, also controling electrical engineering to turn soon, the power upper limit, spread the application for move to bring a series to the direct current thus of restriction.Opposite say in the direct current motive, the alternate current motive especially the rat cage type difference tread electric motor to have structure in brief, the manufacturing cost is low, hard enduring, circulate credibility, support convenience, inertial and small, the dynamic state respond to good, and be easy to toward advantages, such as high pressure,high speed and the big power direction development...etc., past in the design adopted the rat cage type electrical engineering to become pole adjust a technique soon.Although the exchanges double soon elevator the comfortable feeling isn't too good, has structure tightly packed and supports a simple characteristics, adopting to open the wreath control method again, the circuit is simple, the price is lower.
