x-γ radiation personal alarm device PC management software
Abstract:With the rapid development of modern information technology and the wide application of computer network, computer communication technology has become more mature. By using computer to control a machine operation, maintenance and optimization of a wide range of applications. Serial communication is a widely used and practical way of communications, because of the line is simple, flexible application, high reliability, a series of advantages for a long time widely. Computer serial communication in data finance, data communication, fault detection, remote computer monitoring and with extensive practical value, especially under Windows of serial communication can make full use of the resource advantages of the Windows software, realizing multi-duties conditions of external data transmission, information collection and processing.This system using Visual Studio 2010 programming environment to programming. Combined with the.net Framework class library provide SerialPort class to write the cues from χ-γ radiation personal alarm device who the data sent the machine. microsoft access 2003 and serial communication class to achieve a bit machine data collection, storage and thus the analysis of the stored data to understand the different types of machines, within the range of detectable amount of radiation for people to provide some intuitive expression of the detection to the amount of radiation.
