A license plate recognition system is installed in the garage of the community. There are two cars at home and only one parking space. I want to make a license plate of my home, so that two cars can get in. The garage in the community is equipped with a license plate recognition system, and both cars can enter. Of course, it's no problem to enter the garage, but you have to pay extra. But as the owner, he has a parking space at home, but the version allows him to park the same car as long as it does not occupy other parking spaces.

Look at the function of management software. Poor management software, unable to get in; Management software ok, you can enter. The correct management logic is: 2 vehicles (or even more) form a group.

Identify the trigger mode of the system:

License plate recognition system has two triggers, one is a peripheral trigger, and the other is a video trigger.

The peripheral trigger detects vehicle passing signals by using coils, infrared rays or other detectors. After receiving the vehicle trigger signal, the license plate recognition system collects the vehicle image, automatically recognizes the license plate and carries out subsequent processing. This method has the advantages of high trigger rate and stable performance. The disadvantage is that the coil needs to be dug and laid, and the construction scale is large.
