Based On The Mcu And Gprs Research Laboratory Safety Alarm Monitoring System

Currently, Modern vocational school courses have been confined to the classroom,but in the laboratory, and even large workshops and factories. The introduction of alarge number of advanced equipment, laboratories, workshops, equipment safetymonitoring has become an important problem.In the safety monitoring system, wireless communication technologies play agrowing role. Computer network technology into people’s daily lives, reaching out tothe people’s production activities, has also been great development in the field ofindustrial control and security field. Pre-safety monitoring system, there are moremeasured point, the geographic location of the device under test distance away from thesecurity monitoring center, monitoring staff must spend a lot of time, effort and moneyto cloth lines of communication and maintenance, some measured point location of theharsh natural conditions, special conditions, it is not easy to reach, or simply to collectmonitoring information. Wireless communication technology and computer networktechnology to the security monitoring system, to solve these problems.The paper’s main contents has the wireless communication technology (GeneralPacket Radio Service) and the microcontroller technology, involves the application ofsensor technology in the intelligent terminal design of the safety monitoring system, inthis basis, for the school laboratory safety monitoring system solution. First a briefoverview of existing wireless communications technology development status, and theentire structure of the paper; then introduced in the monitoring system design applied tothe characteristics of the hardware, microcontroller AT89S52, GPRS communicationmodule SIM300C and other hardware and applications, and its software developmentand design. Final design based the SIMCOM Company GPRS module andmicrocontroller remote wireless security monitoring system. This monitoring systemand laboratory monitoring acquisition devices through the serial port connected to theMCU AT89S52drive GPRS communication module to establish a connection throughGPRS wireless communication network SIM300C with the Internet, securitymonitoring center connected to the Internet to receive the appropriate safety monitoring information, the security monitoring center and laboratory reliable wireless datacommunication monitoring acquisition devices, smart terminal can be achieved.The system uses microcomputer technology, sensor technology, GPRS technologyto design a laboratory surveillance system of the security, the hidden trouble detectionand the power control. The most important role of the anti-theft system is to increase thedifficulty of thieves committing the crime, and notify the lab assistant promptly, andhave a certain deterrent capacity for deterrence. The hidden trouble detection is toidentify potential hazards in advance, so that the experimenter to make a timely mannerto prevent and eliminate the hidden dangers. The power control uses computer tocontrol the timing off the power of the entire laboratory system, or deal with specialcircumstances of power, and use SMS to notify the relevant personnel.
