基于蓝牙的电梯无线调试系统研究.

Aiming at that traditional elevator adjustment method exist adjustor's heavy workload, long adjustment and other defects, and that the wireless elevator adjustment method currently used was limited by the wireless signal transmission distance, elevator control system, elevator car communication, Bluetooth wireless communication, mobile phone Android technology, etc. were studied, the elevator wireless adjustment system based on Bluetooth was proposed. Bluetooth technology and Android phone technology were applied to the elevator adjustment system in the system designed in this paper, Bluetooth module was embedded in the elevator car controller, and then the Android mobile phone connected elevator car controller, so as to achieve the purpose of elevator adjustment. The system was based on BÖHNKE +PARTNER BP304 elevator control system platform,and tested at a height of 2 meters test tower. The results indicate that using the system to adjust elevator, the reaction time of elevator is 25 ms to 50 ms, which is able to meet the requirements of the elevator adjustment. The system has advantages of low cost, high reliability, high flexibility, and displays visual adjustment results. [ABSTRACT FROM AUTHOR]
