Project background

The 21st century is the era of information technology. Information carriers such as notebook computers and mobile hard disks have entered popularized applications. Whether in commercial, military, or political fields, leaks have occurred from time to time, bringing major issues to relevant countries and enterprises. In order to ensure and facilitate the control of secret-related assets when going out, Jiangsu Tangan has launched an active 433MHz real-time monitoring and management solution for secret-related assets, which monitors the status of secret-related assets in real time in seconds. And successfully applied in the civilian field.

Solution advantage

1. 433MHz active RFID technology is currentlyRFIDThe technology with the longest recognition distance in the technology has the characteristics of strong penetration, strong diffraction, and long transmission distance. Therefore, even if it is impossible to enter certain workplaces, the RFID technology can still be used to check whether the classified assets are in place, which facilitates the inspection of whether the classified assets are in place and prevents illegal means of carrying them out.

2. Real-time monitoring solves the problem of unrecognized carry-out in violation of the general entry and exit system (such as illegal carry-out from a window, etc.). As long as the classified asset leaves the signal coverage area, the system will immediately alarm.

3. Utilizing the long-distance characteristics of 433MHz active RFID technology, the handheld device can also be used to check the presence of classified assets at designated locations.

4. The electronic label adopts special anti-dismantling technology, and the action of the anti-dismantling switch is both sensitive and accurate. As long as there is an attempt to remove the label, the label will emit an alarm signal and the system will automatically alarm immediately.

5. The system can accurately and automatically identify and record secret-related assets brought out (or brought into) the office area, and warns about unapproved secret-related assets brought out (or brought into) the office area, ensuring the management of secret-related assets Effectiveness.

6. High reliability, the hardware is industrial grade product, and the system can work 24H uninterrupted and stably.

7. Ultra-low power consumption, lower radiation intensity than CDMA mobile phones, no radiation damage, safe and reliable use.

　　Scheme principle

The system is composed of “application software server”, “monitoring computer”, “RFID reader” and “RFID electronic tag”.

Working principle: Paste the “RFID electronic tag” on the notebook or mobile hard disk device under management, install a certain number of “RFID readers” in the office area to achieve full coverage of the signal in the office area; when the notebook or mobile hard disk is in the signal coverage In the office area, the “RFID reader” immediately receives the “RFID electronic tag” signal, and feeds the information back to the “monitoring computer”, and the “monitoring computer” processes the received information (if it fails to receive the tag signal or receive When the tag is disassembled, it is judged whether to call the police immediately according to the prior approval status), and the record is stored in the “application software server”, thereby realizing the function of real-time monitoring of the presence of classified assets.

　　System functions

1. Location monitoring: real-time display of the location and time of classified assets

2. Off-location alarm: alarm for illegal off-location of classified assets

3. Departure information of the day: the monitoring terminal displays the number of departures and the time of departure of the current day

4. Anti-dismantling alarm: If the label is disassembled, it will alarm immediately

5. Online application and approval function of the management terminal

6. Online query function: can query historical information of dislocation and disassembly

7. Software shutdown password: you need to enter the password to close the software

8. Cancel the alarm password: you need to enter the password to cancel the alarm
