Design and implementation of an elevator wireless adjustment system

Abstract

The existing cable adjustment system has a long adjustment cycle on the adjustment of flat floor, running curves and involving running part for the car. On the other hand, it usually requires the close coordination between two adjustors. So this paper designs an elevator wireless adjustment system, involving Bluetooth technology, WIFI technology, Android phone technology and microcontroller technology. The elevator wireless adjustment system makes the process of adjustment intuitive, reduces the workload of adjustor and speeds up the elevator adjustment cycle. Compared with the traditional elevator adjustment method, this system makes it possible that using an Android phone as an elevator adjustment tool to debug the elevator with WIFI or Bluetooth. Besides compared with other wireless elevator adjustment methods, the wireless module is fixed on the controller for elevator car instead of the elevator controller, this method avoids the limit of wireless distance, and the adjustor just needs to stay in the elevator car when adjusting the parameter of elevator car instead of running up and down, the real-time adjustment result is able to be seen in the Android phone. Test has proved that the feasibility, effectiveness and reliability of the design of an elevator wireless adjustment system.
