1. Introduction to the system
The physical evidence management system strictly complies with the requirements of the “Specifications for the Management of Physical Evidence in Public Security Organs” and combines the experience of business experts engaged in physical evidence management for many years. It uses radio frequency technology, network camera technology, network technology and database technology to research and develop collective evidence tracking, monitoring, case and A comprehensive physical evidence information management platform with functions such as physical evidence information entry, physical evidence photo collection and storage, query, automatic inventory, and statistical analysis. The system divides the physical evidence into twelve categories according to characteristics, supports the classified storage of physical evidence, and establishes a unique identification code for each physical evidence for electronic file management according to the type and storage location of the physical evidence, and uses radio frequency electronic tags (EPC) Identify and distinguish. When the physical evidence is transferred and returned from the physical evidence storage room, the monitoring system can automatically scan the radio frequency electronic tags on the physical evidence in a non-contact manner and start the network camera to capture and record. If there is no transfer procedure or the wrong physical evidence, the system can Remind by audible alarm. Through the optional handheld library machine, combined with the corresponding library software, thousands of tens of thousands of evidence can be completed within ten minutes. The network function of the system provides classification and statistical analysis of physical evidence, and provides accurate data and an efficient platform for leaders and superior authorities to better supervise and guide the management of physical evidence.

Six, product parameters
(1) Basic parameters
– Use the electronic tag to bind the physical evidence only, “one item, one code”, the electronic tag can store the information of the physical evidence, the life span is more than 20 years, and it can work in harsh environments without fear of pollution;
– Able to quickly and automatically identify and read invisible multiple physical evidence in batches without manual intervention;
– The case and material evidence data items are compatible with the coding rules and standards of the Ministry of Public Security’s case (incident) on-site investigation information;
– Compatible with and support barcode management, and support triple binding of electronic tags, physical evidence identification codes, and on-site physical evidence numbers;
– Support users to customize the unit name of the physical evidence system, and use the customized unit name to display on the login interface;
– Real-time linkage of physical evidence and storage location information, prompting the location of the physical evidence in real time, and graphically displaying the use and idle status of various storage devices;
– According to the physical evidence room environment, you can arbitrarily divide the area and combine freely according to the management requirements; customize the storage device type, from the storage area/storage room to the door or dense cabinet layer of each storage device, etc.;
– Support a variety of equipment such as ordinary physical evidence cabinets, smart cabinets, dense cabinets and electromagnetic cabinets, and support storage linkage (hardware support is required);
– Adopt UI-Facade-Data Access hierarchical design mode, adopt standardized model, stable structure, strong compatibility and scalability;
– The electronic tag radio frequency acquisition terminal and the high-definition image acquisition terminal work continuously without failure for 7X24 hours.
– The system adopts embedded system design; adopts low duty cycle, dynamic antenna switch, and active online electronic tag search technology;
– Support PoE power supply mode, easy to deploy, low power consumption and environmental protection; the interface supports IEEE 802.3af standard;
Seven, functional modules
– Information reminder
Checking the record of physical evidence operation request; reminding the information of the overdue physical evidence; reminding the information of the overdue physical evidence of the storage period; reminding the statistics of the storage status of the physical evidence.
– Physical evidence management
Complete the entire process of physical evidence management from physical evidence registration, storage to storage, transfer, destruction, and loss. Keep all handover evidence and records. The system allows the material evidence temporarily stored in the material evidence temporary storage area to be managed. When the material evidence is officially put into the warehouse, specify the storage location and proceed to the warehouse.
– Traceability of physical evidence circulation
The physical evidence can be quickly indexed according to various query conditions, and the detailed information of the physical evidence, storage conditions, etc. can be viewed; all historical operation records and circulation records of the physical evidence can be traced.
– Case management
Complete case management functions, including case addition, modification, deletion and detailed information viewing, custom coding function, fast indexing, and automatic filing of case-related audio and video.
– Statistical report
Count and export the physical evidence in the library regularly and export it to the file for preservation and record; make statistics on all physical evidence in the warehouse, out of the warehouse, etc. of the unit, and graphically analyze and output;
Make statistics on the historical access of all physical evidence and report output;
Statistic on storage device usage and report output;
– Authority and approval management
Manage system users, assign user login names and user information; assign and manage permissions for users; support multi-unit data management and independent management of subordinate departments’ physical evidence;
Set up the approval process for the release and operation of various physical evidences, and control the physical evidence at different levels according to the importance of the physical evidence, and customize the approval process;
– Operation record traceability
Quickly query the list of all physical evidence information, time, physical evidence status, etc. historically handled by relevant personnel; trace back the physical evidence and the historical operation records of the personnel in a certain period of time at any time.
– Handheld Disk Library
Handheld library, you can export the physical evidence in the library table to the handheld library device at any time. Use the handheld library system for handheld fast library (need to be equipped with a handheld library system). Real-time display of inventory and loss data information and pictures, convenient and rapid for secondary inventory and physical evidence verification.
– Remote physical evidence management
Authorized users of the public security intranet can inquire about their own physical evidence information, physical evidence status, case information, case and related picture information at any time according to their authority; according to authorization, remotely review and approve physical evidence storage and processing applications, and add approval opinions.
– Remote physical evidence traceability
According to authorization, real-time query of the historical circulation record information of the material evidence and trace the historical activity track of the material evidence. Real-time understanding of the unit’s physical evidence storage situation and status, statistical information on the amount of various physical evidence in and out of the warehouse; records of each physical evidence in and out of the warehouse and historical processing operations.
