The intelligent station system is connected with cameras inside and outside the roller shutter door to perform real-time monitoring and linkage, a video analysis subsystem of the intelligent station system adjusts the cameras of the indoor and outdoor ball machines to proper preset positions in the opening and closing process of the roller shutter door, performs image real-time monitoring on videos of the indoor and outdoor cameras, automatically sends a stop command to a roller shutter door controller through a BAS environment monitoring system if an object exists or passes under the roller shutter door, immediately stops the roller shutter door, and simultaneously broadcasts alarm voice in a linkage manner;

the intelligent station system automatically controls the ascending and descending processes in a remote mode and simultaneously allows the emergency stop operation to be carried out through the local control button.

Compared with the prior art, the utility model has the beneficial effects that:

1. the utility model adopts the infrared curtain, the micro sensor, the multi-range automatic stop control and the linkage acousto-optic voice alarm to ensure the safety of the rolling door in the opening and closing process to the maximum extent;

2. the utility model accesses the video data inside and outside the rolling door to monitor the real-time images, and the integrated video analysis subsystem analyzes the video data in real time, links the acousto-optic voice alarm and automatically stops the rolling door when the video data is abnormal, thereby ensuring the safety of the rolling door in the process of remote opening and closing;

3. the utility model can be controlled by remote switch, and can support remote and local emergency stop, thereby improving the efficiency of switching station.
