Elevator speed control method based on wireless sensor network

The control of elevator running speed, real-time, and reliable transmission is the key parameters of the elevator, the traditional elevator speed control method cannot ensure the real-time reliability of elevator transmission parameters, reduce the elevator speed control accuracy. For this reason, a new elevator speed control method based on wireless sensor network is proposed. Introduces the wireless sensor network, gives the car terminal sensor node design process. The operating principle of the elevator is analysed, and the speed curve of the ideal elevator is obtained under the condition of satisfying the high efficiency and comfort. The elevator speed is regarded as the feedback signal, and the fuzzy proportion integral differential (PID) control of the elevator speed is completed through the deviation and deviation change rate between the ideal speed curve and the ideal speed curve. The experimental results show that the proposed method has high control accuracy and good robustness.
