Design And Implementation Of Police Evidence Control System Based On Internet Of Things

From the general criminal case incidence situation,at present,the overall trend of high incidence of criminal cases has not been fundamentally changed,at the same time,with the development of science and technology,but also for the case investigation provides more evidence,more extensive criminal evidence,and more convenient in the detection conditions at the same time,the social demands of the masses of the public security organs of law enforcement to further improve the handling.In all things the evidence has become a prerequisite for the work of law enforcement investigators.On the basis of this,it also puts forward higher requirements on the material evidence management.And from the current situation,the development of the application of information technology in public security evidence is accelerating,such as the Beijing Municipal Public Security Bureau developed a field automatic mapping system,Shanghai City Public Security Bureau developed a fingerprint automatic identification system,etc..Relatively speaking,the degree of information management of public security evidence has not been significantly improved.At present,the public security organs evidence management level is generally weak,the management means is relatively old,the pattern is still in use for decades now,manual and manual management is still the main way.In this case,the direct result of the material evidence management flaws,loopholes,every year,there are a lot of evidence in the custody of the problem,resulting in violation,discipline and even illegal issues,has clearly not meet the needs of public security work,especially the development of criminal technology work.Therefore,to improve the level of management,to achieve information management,has become the reality of public security evidence management.This paper analyzes the application status of the Internet of things technology and the reality of the current physical evidence management,around the realization of the "evidence must be preserved,identification must be accurate," the goal,combined with the national laboratory accreditation requirements,the construction of evidence preservation center and the center of the goods.Frequency Identification Radio(RFID)is used as the information medium.The system of the Public Security Bureau evidence management system is discussed,which is based on the RFID technology.The system has been analyzed.The main functions of the system are analyzed.The system has been analyzed.Information management system is the inevitable choice for the development of the Public Security Bureau in the future,with information as the lever and fulcrum,improve the information construction,reform the traditional evidence management,realize accurate,timely and reliable data information collection,protect evidence and system data security,construction of digital evidence management and intelligent management system platform,improve the comprehensive management level,business level and academic level.In this paper,a material evidence management system based on Internet of things technology is realized.The system combines the actual needs of public security scene investigation and evidence collection,and realizes the whole business flow management,and ensures the security and reliability of the evidence management.The system has achieved good results in the practical test,which provides a strong guarantee for the safety of the people's personal and property.
