Serial server module application

(1) Supermarket storage cabinet

In supermarkets, customers need to enter the supermarket to shop, and their own bags and other items are not allowed to be brought in. Automatic storage cabinets can solve this problem very well, automatically register faces, automatically recognize faces and switch on and off.

The implementation principle is: place the serial port server module in the supermarket storage cabinet, DI and DO links control the door switch, and the other end is connected to the computer. At the same time, this system also uses a camera to collect face data. The first successful face recognition will automatically open a storage cabinet. When the last recorded face appears in front of the camera again and the comparison with the last face is successful, the serial port server module will control the corresponding locker to open.

(2) Automatic weighing

On highways or on certain special road sections, cars need to be weighed.

Implementation principle: There is a weighing device buried under the road, and the serial port server module is used to connect the weighing device and collect data. Send the collected data to the computer in the control room to achieve unmanned weighing. Through the background system, the corresponding price can also be automatically calculated and displayed on the display screen.
