How to install monitoring in the elevator?
Elevator is a complex closed environment. Currently mature wireless monitoring has become the primary choice for elevator monitoring applications. The wireless bridge is a transmission device in wireless monitoring, which is convenient to install and low in cost. However, in the actual elevator monitoring installation process, many problems will occur. Here are a few points, I hope to help everyone in the actual installation.
Note one: Blind entry?
Elevators are special equipment and are dangerous. Do not enter the site blindly.
Before installation, we need to go to the property to understand the wiring situation of the on-site elevator and monitoring.
First contact the elevator maintenance personnel. Outside personnel must be led by the elevator maintenance personnel to enter the site. (Elevator operators are required to hold special operation operation certificates issued by the General Administration of Safety Supervision to work.)
Note two: how to solve the bridge power supply?
Different elevator brands and structures are different, and the configuration of the top and bottom of the car is also different. The power of the elevator car roof of the reconstruction project is likely to be occupied by the camera. Where does the bridge get its power from? When surveying, pay attention to whether there is a power strip at the top of the car. If there is no power strip, you need to prepare another power strip to facilitate power extraction.
Note three: Where is the bridge installed?
Select the installation point of the bridge to avoid obstructions as much as possible, especially metal materials will affect the signal. The bridge on the top of the elevator car can be installed on the upper railing; the other is installed on the foundation pit? It is possible that the foundation pit will accumulate water and affect the bridge signal transmission, so it is a good method to fix it on the elevator shaft wall.
Note four: What fixed the bridge?
How to fix the bridge at the top or bottom of the elevator shaft? When the bridge leaves the factory, most manufacturers' accessories only include hoop or cable tie, and there is no bracket, so don't forget to buy a bracket! Hoops and cable ties should also be held tightly when fixing the bridge.
