1. Project background
Personnel attendance technologies, such as fingerprint recognition, 13.56MHz RIFD swiping, face recognition, etc., require employees to be close to the device to achieve this. It is easy to cause a large number of queues for attendance on and off work, and channel congestion leads to many complaints. Regarding the departure situation of employees during working hours, if the employee does not go to the designated location to perform actions such as swiping the card, the attendance of these departures cannot be counted.
Haiweida’s 433MHz RFID-based personnel real-time attendance solution makes attendance more convenient, solves the problem of channel congestion, and can also record the time of departure in real time, making attendance more refined. It is an ideal choice for real-time attendance of enterprises and institutions!
2. Program features and advantages
1. 433MHz active RFID technology has the characteristics of strong penetration, strong diffraction, and long transmission distance. It is suitable for various complex environments and has strong environmental adaptability.
2. In view of the penetrability and strong diffraction of 433MHz, the electronic tag can be hung on the chest in the form of a badge or placed in a clothes pocket, which is convenient to carry.
3. Automatic long-distance recognition, long reading distance (adjustable from 1 to 150 meters), no need to close the card, just follow the normal path to enter and exit the work area to identify, the system can identify up to 200 people at the same time to pass through, completely resolved This solves the problem of congestion in the attendance channel to and from get off work.
4. Real-time monitoring, the reader continuously monitors the electronic tags of the personnel, as long as the signal coverage area of the reader is left, the system will automatically record the time of leaving the post.
5. Ultra-low power consumption, no radiation damage, safe and reliable to use.
6. Due to the powerful long-distance characteristics of 433MHz RFID, it gives great convenience to the application of handsets. For emergency evacuation drills, etc., you only need to use a mobile phone with a portable Bluetooth reader or handheld to scan the information of the people in place at the assembly point, which is convenient for the emergency evacuation of personnel.
Three, the principle of the scheme
The system is composed of “application software server”, “monitoring computer”, “RFID reader” and “RFID electronic tag”.
Working principle: Distribute “RFID electronic tags” to each employee to realize one person, one card. Employees hang the “RFID electronic tags” on their chests or put them in their pockets. The monitoring computer is connected to the RFID reader. When the RFID card worn by the person is scanned by the reader, the reader will send the acquired RFID card information to the monitoring program, and the monitoring program will register for work, leave work, and leave. Bit registration, etc. are judged, and corresponding records are generated and sent to the database for system users to consult.
