Detection grid system for intrusion early warning

The invention belongs to the technical field of detection grids, and particularly relates to an intrusion early warning detection grid system which comprises a cloud database, a detection module, a monitoring module and an early warning module, the cloud database is linearly connected with the detection module, the cloud database is linearly connected with the monitoring module, the cloud database is linearly connected with the early warning module, and the early warning module is linearly connected with the detection module. The detection module comprises a grid detection unit and a radar detection unit. According to the invention, the system can quickly identify and record the outside personnel by analyzing the outside personnel entering and exiting and performing data labeling on the outside personnel entering and exiting in the monitoring picture, so that the infrared correlation detection grid system can learn and memorize for a long time; when external personnel who often enter and exit enter and exit t
