Project background

With the emphasis on asset management by the state, enterprises and institutions, the informatization construction has gradually developed from the original focus on the informatization of financial management to the informatization of asset management. Strengthen the scientific, standardized and standardized management of assets; give full play to the role of assets in work; realize real-time monitoring of asset inventory and dynamics at all levels; achieve unified planning, unified management, and unified dispatch; use powerful network facilities to achieve Units at all levels, enterprises and institutions send data online to achieve the goal of asset tracking management. Realize the dynamic management of assets within the scope of supervision, standardize and modernize asset management, and further improve the asset management level of enterprises and institutions.Jiangsu Tangan’s active 2.4GHz asset real-time monitoring and anti-theft alarm management solutions have established and adopted advancedRFIDThe system uses advanced RFID equipment to collect data through the tags placed on the assets, and through the intelligent decision-making of the back-end application software, it realizes the regionalized management of the assets and ensures the safety of the assets.

Solution advantage

1. The 2.4GHz active RFID technology can meet a large monitoring area and has the ability to identify and record multiple tags at the same time. The reading distance can reach more than 50 meters indoors, the reading distance can be adjusted by software, and the information of 1000 tags can be recognized and processed at the same time per second. Therefore, within the effective scope of asset management and control, relying on the RFID technology can check whether the controlled assets are in place in real time, effectively preventing the illegal movement of the controlled assets.

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 controlled asset leaves the signal coverage area, the system will immediately alarm.

3. The electronic tag 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.

4. The use of this system can realize the accurate and automatic identification and recording of the control assets brought out (or brought into) the designated area, and the unapproved control assets are brought out (or brought into) the designated area to give an alarm to ensure the effective management of the managed assets. sex.

5. The system has complete functions and practical standards, and the system settings emphasize practicality; it meets the requirements of relevant domestic and foreign standards, is simple to use and easy to operate.

6. The system maintains technological advancement under the premise of satisfying reliability and practicability, and is especially in line with the latest development trend of computer technology and network communication technology and has mature applications.

7. The system has extremely high safety and reliability, and has long-term and stable working ability.

Scheme principle

The system consists of “database server”, “application server”, “monitoring computer”, “RFIDReader“And “RFID electronic tags”.

1. Installation plan:

1. Install RFID tags for assets that need to be controlled to form a one-to-one identity correspondence.

2. Install RFID readers at key locations in the asset management and control area to realize the identification of RFID tags.

3. Install asset management software on the monitoring computer, which mainly realizes mutual communication with RFID readers and exchange of data information, so as to accurately identify the RFID tag ID number and corresponding related data information, and perform related asset management operations to realize assets Computer management of changing data.

2. Working principle:

In the 2.4GHz active RFID asset real-time monitoring and anti-theft alarm management system, “RFID electronic tags” are installed on the asset equipment under management, and a certain number of “RFID readers” are installed in the office area or the control area to realize the office area Or the signal in the control area is fully covered; when the managed asset is located in the office area covered by the signal, the “RFID reader” immediately receives the “RFID electronic tag” signal and feeds the information back to the “monitoring computer”. The received information is processed (if the label signal is not received in time or the label is disassembled, it is judged whether to call the police immediately according to the prior approval), and the record is stored in the “application server”, thereby realizing real-time monitoring The function of whether the asset is in place, and finally the historical data information is stored in the “database server” for storage.

The working principle of RFID is shown in Figure 1. The RFID reader sends out a certain frequency radio frequency signal through the reader antenna. When the tag enters the magnetic field where the reader antenna is located, the tag sends its own data information to the reader, and the reader performs data information Collect and transfer data information to the computer for processing.

System functions

User Management:

Mainly add, delete, and change the management account. By setting different user rights, the requirements for different management rights of the system are met.

Label management:

It mainly includes tag information writing, tag rebuilding function, tag status change, etc.

asset Management:

It mainly includes asset information entry, asset acquisition management, asset outbound management, asset authority management, asset inventory management, etc.

Monitoring and management:

It is mainly for real-time monitoring and related settings of managed assets.

Alarm management:

The system alarm categories can be divided into alarms for asset disappearance, alarms for illegal asset removal, alarms for illegal removal of tags, alarms for asset going out, etc.

Query stats:

Mainly can realize asset classification inquiry, personnel inquiry, inventory inquiry, asset outgoing inquiry, alarm inquiry and so on.

System architecture

The real-time asset monitoring and anti-theft alarm management system requires a database server, an application server, and a background monitoring terminal. The third-party data interface is mainly used to provide a linkage interface with the video monitoring system and the access control monitoring system. Managed assets read the RFID information of the assets passing through the monitoring points through the reader devices deployed at each monitoring point, and determine the access authority of the assets through the background system. If illegal items enter the area, the system will alarm to achieve Safe management of assets.

Figure 2 shows the overall network topology of the real-time asset monitoring and anti-theft alarm management system.
