The Research And Design Of Forensic Identification Measurement Analysis System Based On ARM

With the rapid development of electronic technology,the performance of ARM system will also be improved.While the electronic field which based on ARM system has also gone through earth-shaking changes,the ARM measuring system is also becoming increasingly popular.ARM processor testing equipment has the following advantages such as low power consumption,smaller in size,better performance,etc.This paper will give an analysis from the perspective of the portability,intelligent,practicability and the compatibility of the measuring system and will focus on improving the traditional forensic measurement analysis system data transmission mode.The research will simplifying the manual operation,improving work efficiency,enhancing the data processing ability as well as improving the system compatibility.After comprehensive consideration,we decide to take the ARM architecture processor as the main controller,and take DS18B20 package insert type sensor as the temperature sensor,and then use the humidity sensor and light sensors for environmental monitoring to research the rectal temperature.Based on the object cooling rule,combined with the environmental temperature,as well as the body influence factors such as clothing,coverings,we build mathematical model to deduce the time of death abstraction and establish used to deduce the mathematical model of the time of death and get more accurate algorithm of the time of death,thus improve the ability of data analysis and accuracy.The paper has its innovative opinions and practicability such as using wireless sensor technology for data transmission to make the equipment compatibility more stronger improve the ability of data analysis and accuracy.Its innovative and practical embodies in: using wireless sensor technology,data transmission equipment compatibility is stronger;Using a 5.4-inch touch screen for Human-computer interaction which can be manually entered various immeasurement factor data,which all changed the traditional forensic oneness measurement analysis system.This paper established the mathematical model which can deduce the time of death,and also gives an more accurate analysis on algorithm of the time of death.The temperature data can be collected and recorded automatically and establish a test database,thus improve the accuracy of the recorded test data and the data processing ability of the system.Time collected and the analyzed results will be sent to the mobile phone via bluetooth which provide great convenience for forensic workers as well as provide important data and analysis results to the entire forensic identification system.
