Elevator Wireless Monitoring
BackgroundThe traditional elevator CCTV system sent the video signal with dedicated video cables of elevator.The elevator subscribers have been increasing as time flies. It’s been reflected that circuit had became useless after 6 months using with twists and turns hundreds of time everyday. We realized that replacing the damaged circuit with new is complex and unreasonable, we decided to solve the issue about complicated wiring and circuit aging by wireless transmission to get done this project.
Demands AnalysisMonitor the elevators all day long with digital network monitoring.Call the video record immediately to get the solution and evidence once the unexpected situation occurred.The video images are supposed to be reliable and clear.

Environment Analysis
Elevator Front System DesignThe front camera connect with the wifi bridge A(CPE) by cables, which is fastened to the top of the elevator .Set up wireless router B(AP) on the top and then connect it to wirless router C (CPE) with cables.Wireless router C is about to transmit the data to relay D.Relay D and relay E are charge of broadcasting.Wireless router E connects to control center through the wireless router F.Monitor the inner elevator with network cameras.The signal collector is about to gather the state and datas,then transfer to wireless bridge.The central host can do remote simultaneousmonitoring and the video shows how the elevator works.
We will install A point with DIP356-H as a sender considering the state of running up and down of the elevator, and install the same model in B point as a receiver.1.Outdoor sender
We choose the roof of a higher building as a sender point considering transmission quality, and install several DIP356-H on it.2.Outdoor receiver
We install several DIP356-H as receivers in open space .3.Control room interface
This is a view of the monitoring center.
Using the inverter and special modulation techniqueto choose4.9-6.1 channel for avoiding the interference with the 2.4G spectrum wireless
