The alarm signal of abnormal entry is issued through various alarm detectors at the front end of the system, and a strong sound and light alarm signal is sounded in the alarm zone. At the same time, send the signal to the security monitoring center, start the related linkage equipment, complete the camera, turn on the lights and other work. The library of the "Siku Quanshu" is set up as a partial three-level deep protection system, with a three-level protection system of surveillance area, protection area and restricted area. The infrared protection and fire alarm monitoring area is used around the protection building. The stairwell adopts dual-detection alarm and TV monitoring and protection area. The book library and monitoring room adopt dual-detection alarm, TV monitoring and access control to control the ready-made forbidden zone. Stairwells and entrances and exits are equipped with dual-detection alarms and ready-made surveillance areas. The protection zones, passages and stairwells are equipped with dual-detection alarms and TV monitoring ready-made protection zones. In addition, the sound recovery device is installed in the library channel and the eight protection zones, and the security window, the security door and the access controller should be installed in the protection zone.
Perimeter defense system The general perimeter defense alarm system is composed of detectors, alarm controllers, linkage controllers, analog electronic screens, searchlights, and sirens. According to the characteristics of the topography and geomorphology of the site, the surrounding area of ​​the pavilion is a complex irregular curved shape. It is difficult to prevent the infrared radiation on the perimeter of the pavilion. Therefore, the local infrared radiation prevention alarm system is used--the infrared radiation detector is installed.
Access Control Systems Previous contact access systems have been slowly replaced by current inductive access systems with more features and benefits. The inductive access control system can effectively manage and restrict the entry and exit personnel, and can effectively limit the access rights of staff and non-workers, and can register the information about the entry and exit personnel, which is convenient for archiving and future inquiry. In terms of improving the safety of the warehouses in the museum, on the other hand, it not only reduced the number of staff, but also greatly reduced the workload of the staff. The system is mainly composed of access control management host, system software, card reader, electromagnetic lock and RF card.
