First, the system background

Material evidence is one of the evidences stipulated in the criminal procedure law, and it is the important evidence to prove the crime. It has objective reality, irreplaceable, legal. Many of the physical evidence obtained from crime scenes are surveyors, technicians who work day and night, and are carefully collected and extracted in extremely difficult and harsh conditions. Therefore, the work should strengthen the norms and requirements, the use of modern information technology to improve the quality of management, evidence management to achieve a scientific, to make up for deficiencies in the work, thereby enhancing efficiency.


Second, the system components

Public Security Bureau physical evidence management system consists of RFID tags, read and write equipment, application systems, alarm systems and other components.

Third, the system process

 

● Acquisition layer: RFID tags, one-dimensional bar code, handheld terminal, four-channel fixed reader, antenna.

● Communication layer: The tag information of the physical and chemical tags collected by the reader can be transmitted to the background application system through the network for analysis. The communication interface of the transmission can be selected according to the needs of the users, such as RS232, RJ45 and WIFI.
● application layer: the completion of the collection of data processing, including physical evidence storage management, physical evidence out of library management, alarm and other functions.
● Data integration layer: complete with other systems within the enterprise interconnection, data sharing and transparency.
 Public Security Bureau physical evidence management system hardware consists of RFID tags, one-dimensional bar code, fixed reader, handheld reader, application systems and other components. In the system, the handheld computer is mainly used to scan the physical evidence in the warehouse to find out the physical evidence needed quickly and accurately. Combined with the fixed reader, the data entry and storage control system is realized, and the data entry system is combined with the application system. Of the Public Security Bureau evidence management system.

 

Fourth, the system features

◇ digital evidence management
● application system can quickly check the physical evidence information, physical evidence out of the library data automatically uploaded;
● physical evidence are affixed with labels and one-dimensional bar code, can quickly scan the physical evidence information and storage location;
● handheld display the physical evidence to read the information to ensure the correctness of taking out the physical evidence;
◇ high safety performance
● RFID tags combined with one-dimensional bar code, to ensure that the physical evidence of information fully identified;
● Each electronic tag has a unique code, rapid identification of physical evidence, will not lead to confusion due to duplication of coding;
? Prevention of "entrainment" of physical evidence that is not registered in the system will not be entrained in the normal physical evidence;
● The handset and the fixed reader cooperate to improve the correctness of the system;
◇ data automatically upload to improve work efficiency
● Automatic data collection and storage, reduce human error;
● Improve the accuracy and reliability of physical evidence management;
● reduce the cost of manual management;
◇ easy to install, easy to expand
● Label according to the actual situation and diverse choice;
● Can be easily extended to increase the positioning of valuable equipment, fixed assets and physical evidence;
● Combination of peripheral devices can be visualized management, easy to expand.
● RFID tags combined with one-dimensional bar code, to ensure that the physical evidence of information fully identified;
