Description

Technical Field

[0001] The utility model relates to the technical field of camp management equipment, and in particular to an intelligent camp access control system based on RFID. Background Art

[0002] The camp is usually an organized, highly restrictive area with specific management regulations and safety measures. In these places, entry and exit need to be strictly managed. The commonly used technical means are manual monitoring and video monitoring. The former is monitored by the management personnel (gatekeepers) in shifts, and the latter is achieved by setting up video monitoring equipment around the camp to achieve 24-hour monitoring of the camp. Although the video monitoring system can monitor suspicious targets through real-time recording and video dynamic capture, the identification of suspicious targets by this monitoring still requires the management personnel to make decisions. Therefore, this traditional monitoring management technology is not intelligent enough and is not very convenient to use. The reliability of monitoring is heavily dependent on the professional quality and sense of responsibility of the monitoring personnel. After all, human energy is limited, so it is difficult to achieve real-time high-quality monitoring management.

[0003] Today's smart camps use the concept of smart camp system construction, gather human wisdom and give things intelligence, and realize data sharing and equipment network-wide connection in accordance with the requirements of "digitalization, intelligence, networking, interactivity, collaboration, and integration" to create a smart and safe camp. Therefore, a corresponding smart camp access control system is needed, such as the camp access control system based on radio frequency identification technology disclosed in application number CN201220377706.6, which saves human resources and improves the degree of intelligence; the sensor wakes up the sensing antenna only when it senses that someone or a vehicle is approaching the sensing antenna, which reduces system power consumption and usage costs, and can also extend the service life of the sensing antenna; strict management of one person and one card is implemented, which can record detailed entry and exit records of people in the camp, including the name, department, entry and exit time, etc. of the people entering and leaving the camp, to ensure that the management of the camp is traceable and improve the reliability of camp management.

[0004] However, the above technical solution still has some technical problems. For example, the sensor wakes up the sensing antenna after the approaching person is recognized, but the approaching person is just passing by and has no intention of entering or leaving the camp, which causes unnecessary waste. At the same time, if the access card with the RFID chip is lost in the camp, it is inconvenient to find it, and it will also cause unnecessary trouble. Utility Model Content
