Elevator Safety Monitoring and Early Warning System Based on Directional antenna transmission technology

In order to solve problems of the absence of security protection and the lack of early warning mechanism in the current elevator operation process, elevator safety monitoring and early warning system based on directional antenna transmission technology was proposed. The system includes sensor module circuit, microcontroller module circuit, display module, directional antenna transmission module, remote server and data monitoring system. Design ideas of hardware development, remote server and data monitoring system are introduced. Two version monitoring software are written, one for PC monitor, the other one for mobile phone monitoring. In order to improve data transmission distance, transmission rate and transmission quality, automatic antenna alignment system is designed, which combines the advantages of directional antennas and omnidirectional antennas transmission technique. To overcome problems such as instability of the alignment process, delay and other factors, DMC (Dynamic Matrix Control) algorithm should be used in the system and optimal control of the antenna angular alignment will be achieved. The system can continuously transmit real-time elevator’s working status information and environmental information, and it also send commands to notify elevator company managers once an abnormal conditions occur in the elevator, so that people can take urgent measures and maintenance measures. This system can be applied to real-time warning of all-types elevators.
