More and more residential, property and shopping mall elevators are equipped with wireless monitoring systems. Due to the inconvenience and inconvenience of wiring, more and more elevators have chosen wireless monitoring. Modern elevator wireless monitoring is divided into analog wireless monitoring systems and digital wireless monitoring systems.
Let's take a look at the installation techniques of elevator wireless monitoring and analysis of some common problems:
First, elevator simulation wireless monitoring method
Let us first talk about the principle of analog monitoring: simply by the camera (front-end) through the transmission device to the back-end storage (DVR or monitoring host) for video and real-time preview. Therefore, we can start from these parts.
Elevator simulation wireless monitoring necessary tools: screwdriver, pliers, multimeter, measuring instrument, engineering treasure and so on.
Elevator analog monitoring transmission
1, through the elevator with wireless transmission equipment transmission, and then laying a video cable in the shaft, directly to the monitoring room
2. The elevator pipeline is transmitted by wireless transmission equipment, and the elevator engine room transmits light to the monitoring room.
Analog camera without image detection method
First, check whether the back-end video capture card or hard disk recorder has loose interfaces and whether the power supply is normal. If everything is normal, you need to go to the front end to check if the camera power and the camera are working properly. Surveillance cameras have no video signal. First check if there is any problem with the power supply of the camera. Use a multimeter to check whether the 12V output voltage is normal. If it is normal, continue troubleshooting other fault points. If it is not normal, replace the 12V power supply and do another test. After checking the camera power problem, and then detect whether the camera is faulty, you can use the engineering treasure to directly detect whether the camera has an image. If there is no image, the camera is proved to be faulty. If the image is normal, the camera is proved to be normal, and then the test is used to connect. The line is normal.
Second, digital elevator wireless monitoring
The digital elevator wireless monitoring is transmitted through the wireless bridge in the elevator channel, and the receiver is connected to the switch so as to access the formed LAN. The back end passes through the computer and the web page is displayed.
Several installation methods of digital elevator wireless monitoring
1. If it is close to the equipment room and can be transmitted through the wireless bridge, the receiving bridge is directly connected to the equipment room with the network cable.
2. If you are far away from the computer room, you can use a wireless bridge. The camera is equipped with a transmitter. The elevator room is equipped with a receiver. It is connected to the equipment room through an optical cable.
3. If it is far from the computer room, it is inconvenient to arrange the optical cable for distribution. After the elevator channel is transmitted through the wireless bridge, the cable is connected to the roof of the building and the signal is transmitted to the equipment room through the wireless bridge.
Digital monitoring without image detection method
First detect if the camera is broken, if it is not bad, check the network transmission, especially if the crystal head order is correct, whether the crystal head is pressed well, use the line tester to test whether the network is connected, or if the ping camera address through the dos command is there It is an optional wireless bridge that detects whether the network bridge is damaged or not, whether the wireless bridge network is unblocked, and whether the wireless bridge installation method is correct.

12 Layer PCB

Cheap 12 Layers PCB stackup and thickness


We are one of the few manufacturers in China that can manufacture 12-layer PCB boards on a large scale.

The 12-layer board can usually be manufactured smoothly on a 1.6mm thick FR-4 board. But we've seen more 14- to 16-layer boards are being fabricated into 1.6mm thick boards, but the number of manufacturers that can produce them is limited to manufacturers that can produce HDI PCB boards. Those who can produce HDI Circuit boards are increasing.

12 Layers PCB– Heavy industry boards or boards with may tracks

For industrial PC design, 12-layer circuit boards are more popular. Compared with other multi-layer PCB circuit boards, such as four-layer circuit boards, 8-layer circuit boards, 10-layer circuit boards, The price of the 12-layer PCB is still reasonable.
