System Overview

In recent years, as the application of computers has become more and more widespread, the traditional security methods of secret-related entities have fallen far short of the needs of the development of informatization. How to ensure the safety of computers and data in applications and prevent leaks has become an important task at present.
U disks, mobile hard drives, personal notebooks, etc. are the main carriers of information dissemination. There is currently no good monitoring method for its use. Most of its monitoring uses manual methods, which can no longer adapt to the current information security control. .
In response to the above situation, Suzhou Mulan Electronics has innovatively launched RFID-based products as the core, combined with the company’s secret-related asset management system, to replace the traditional secret-related carrier management methods. The secret-related carrier must be approved by the leader to bring out the surveillance area. The remote identification and judgment of U disks and mobile hard disks brought into or out of the monitoring area will be carried out. If illegal carriers are found, they will be reported to the police immediately, which greatly improves the scientificity, effectiveness and safety of the management of secret-related carriers. .

　　Program overview

This system is mainly composed of the following modules: low-frequency activation system, long-distance card reading system, abnormal alarm system and LED display system.

1) Working principle diagram of low-frequency activation system:

The dual-frequency tag is in a deep sleep state under normal conditions, and the power consumption is extremely low, and the overall power consumption is not more than 3uA. Only when a person or object with a dual-frequency tag enters the coverage of the low-frequency signal source (0.5-7m), the low-frequency signal detection chip of the dual-frequency tag will detect this signal and immediately wake up the sleeping MCU , Make it enter the working state. Then send the relevant information (including your own ID number—-unique code, battery capacity information, low-frequency signal source number, etc.) in the form of high frequency to the far away card reader or dual Frequency card reader.

The signal coverage of low-frequency wake-up is 0.5-7 meters, and the signal range of high-frequency transmission is 0-50 meters (maximum 80 meters). In other words, it can be positioned closer and more accurately without reducing the original communication distance of 2.45GHz in essence.

Advantages of using low frequency activation:

1. Ultra-low power consumption, the dual-frequency tag is in a deep sleep state under normal conditions, and the power consumption is extremely low, and the overall power consumption is not more than 3uA.
2. The accuracy rate is high, because the low frequency coverage (0.5-7m) will only be recognized within the range again, avoiding the interference of other long-distance electronic tags.

2) Working principle diagram of long-distance card reading system:

The activated dual-frequency electronic tag sends relevant information (including its own ID number —- unique code, battery capacity information, low-frequency signal source number, etc.) in the form of high-frequency signals to a longer distance in the prescribed format Card reader or dual-frequency card reader. The signal range of high frequency emission is 0-50 meters (maximum 80 meters). In other words, dual-frequency electronic tags can be positioned closer and more accurately without essentially reducing the original 2.45GHz communication distance. After the card reader receives the high-frequency wireless signal, it will parse the acquired data, parse the information carried by the dual-frequency tag and store it temporarily in the reader and use a fixed protocol to wire (RS485/RS232/Ethernet/light Etc.) or wirelessly (GPRS/CDMA/WIFI/3G, etc.) to upload the information to the management dispatch center.

Advantages of using long-distance card reading:

1. Long distance: The reading distance does not need to be manually close to the card or to pass in the designated area to recognize, realize automatic recognition, advanced anti-collision technology, support multi-label recognition and writing, which can effectively alleviate the excessive number of vehicles entering and leaving the warehouse during peak hours. Congestion caused by queuing to swipe cards;
2. Stable operation: The active card has a stable reading distance and is not easily affected by the surrounding environment. Moreover, the active card can effectively break through the shielding effect of the automobile’s explosion-proof metal mesh, and smoothly exchange data with the reader. Using channel isolation technology, multiple devices do not interfere with each other;
3. Supports high-speed mobile reading: the moving speed of the identification card can reach 200 km/h.
4. High reliability: it can operate normally within the ambient temperature of -40℃-85℃ (MTBF≥70000 hours), especially under the low temperature in the north and high temperature in the south, it has more advantages, and it can effectively resist the air in the coal mine environment. The normal use of equipment can be guaranteed in environments with high dust, pollutants, and rainy weather.
5. Encrypted calculation and authentication to ensure data security and prevent link eavesdropping and data cracking; high anti-interference and lightning protection design has no special requirements for various interference sources on site, meets industrial environment requirements, and is convenient and simple to install. There is no need to apply for and pay for the ISM microwave frequency band that is open worldwide.
6. Ultra-low power consumption: long service life, low average cost, safer and healthier for the human body, and no radiation damage. Configurable microwave module working mode, adjustable transmission power;
7. Multi-identification: It can identify more than 200 signs at the same time. If there are more than 200 signs on the spot, we have ways to deal with it.

The ML-M2000DX long-distance card reader has a control alarm function, which can remind people to pay attention in the form of an alarm when an abnormal situation occurs.

4) LED large screen display function:

Relevant information can be displayed on the LED display screen, so that it is convenient to view the information, and if there is a problem, it can be dealt with in the first time.

5) The overall working principle diagram of the system:

Working method: When the article carries the dual-frequency electronic tag passing by, the low-frequency signal source first activates the dual-frequency electronic tag, and the activated dual-frequency electronic tag stores relevant information (including its own ID number-unique code, battery) The battery power information, the number of the low-frequency signal source, etc.) are sent to the reader at a long distance in the form of high-frequency according to the prescribed format. The reader reads the relevant information and passes through the confidential asset management software and computer. The processing judges whether the current operation is legal and makes corresponding judgments. If the current operation is an illegal operation, an alarm will be issued. If it is a legal operation, no alarm response will be made, and only relevant information will be recorded. The LED display screen displays relevant real-time information for easy viewing.
