[Abstract]:As an indispensable loading tool in modern architecture, elevator has become a transportation tool closely related to the daily life of residents. The elevator is monitored in real time by computer to detect and troubleshoot in time. It is very important to strengthen the real-time management of elevators and ensure the safe operation of elevators. In recent years, the wireless monitoring system of elevator status information has become one of the hot spots in the research of new elevator technology at home and abroad. Aiming at wireless monitoring of elevator status information, based on the in-depth study of existing methods and techniques, this paper develops the elevator status information collection terminal, builds the data transmission network based on zigbee, and compiles the software of the data monitoring center bit machine. The wireless monitoring system of elevator status information based on ZigBee is completed. The main work is as follows: firstly, the method of collecting elevator state information is discussed in detail, and the detection methods including elevator temperature, humidity, noise, acceleration, vibration, elevator position, traction current, voltage and so on are studied. The principle and application of a series of intelligent sensors are introduced. The improved capacitive triaxial acceleration sensor with high precision is used to reduce the damping factor of the sensor and improve the resolution of the sensor. At the same time, in data processing, oversampling technology is used to further improve the resolution of acceleration detection. In the elevator vibration detection, wavelet threshold noise reduction technology is used to improve the detection accuracy. Secondly, after analyzing the performance structure of the elevator, it is determined that the state information collection terminal is composed of three elevator status information acquisition modules: elevator car, machine room and traction machine, which is responsible for collecting the state information of each elevator in real time. Each terminal acquisition module takes the Cortex-M3 intelligent processor as the core and combines various sensors as the module to input the elevator real-time status information. Each module is equipped with DGUS high-definition LCD touch screen, and a man-machine interactive interface is developed, which can display the elevator temperature, humidity, noise, acceleration, vibration, elevator position, tracer current in real time and dynamically. Voltage and other status information. Each terminal module is connected to the zigbee wireless transmitting node and uses the zigbee wireless communication technology to build the data transmission network based on zigbee and communicate with the wireless gateway. Finally, the data processing software of data monitoring center is designed and developed by using VisualC# tool. The data center receives elevator state information data from zigbee wireless network through wireless gateway and stores information through data processing software for further data analysis. Through the field test of the system many times, the functions of the system have been fully tested, and the design requirements have been better achieved.
