【摘要】：现今的职业学校很多课程的学习已经不局限于教室，而是在实验室，甚至是大型的车间和厂房。在实验室、车间中引进大量先进设备，因此，设备的安全监控成为重要的问题。在安全监控系统中，无线通信技术所起到作用越来越大。计算机网络技术深入到人们的日常生活当中，，也深入到人们的生产活动当中，在工业控制领域和安全保障领域也得到了很大的发展。前期的安全监控系统中，有较多的被测点、被测设备所处的地理位置离安全监控中心距离远，监测人员就必须花费大量时间、精力和金钱来布通信线并进行维护，有些被测点所处位置的自然环境恶劣，条件特殊，人们不容易到达或者根本不能由人来采集监控的信息。无线通信技术和计算机网络技术加入到安全监控系统中，就解决了这些问题。本论文的主要技术路线是无线通信技术（General Packet Radio Service）和单片机技术，在安全监控系统的智能终端设计中涉及传感器技术的应用，在此基础之上，提出了适合学校实验室安全监控系统的方案。首先对现有的无线通信技术发展现状进行简要概述，并提出了整篇论文的结构；然后介绍在监控系统设计中应用到的硬件，单片机AT89S52，GPRS通信模块SIM300C等硬件的特点和应用，并对其软件开发进行设计。最终设计了一种基于SIMCOM公司的GPRS模块以及单片机的远程无线安全监控系统。此监控系统与实验室监控采集设备通过串口相连，用单片机AT89S52驱动GPRS通信模块SIM300C，通过GPRS无线通信网络与Internet建立连接，安全监控中心连接Internet接收相应的安全监测信息，安全监控中心与实验室监控采集设备的智能终端的可靠数据无线通信得以实现。本系统是一套安全防盗、隐患探测和电源便利控制于一体的实验室监控系统。其中，防盗系统最大的作用就是提高盗贼的作案难度，以及及时通知实验员，并且具备一定阻吓和威慑能力；隐患探测主要是为了提前发现潜在的危险，以便实验员及时做出防范，消除隐患，防止不必要的意外发生；电源便利控制只要是计算机控制整个实验室系统的电源定时通断，或者特殊情况断电处理，并能使用短信通知相关人员。
[Abstract]:Nowadays, the study of many courses in vocational schools is not confined to classrooms, but in laboratories, even large workshops and workshops. In laboratories, workshops, the introduction of a large number of advanced equipment, so. The safety monitoring of equipment becomes an important problem. In the security monitoring system, wireless communication technology plays a more and more important role. Computer network technology goes deep into people's daily life, and also into people's production activities. In the field of industrial control and security has also been a great development. In the early security monitoring system, there are more points to be measured, the geographical location of the equipment is far from the safety monitoring center. Monitors must spend a great deal of time, energy and money to distribute and maintain communication lines, some of which are located in poor natural environment and special conditions. It is not easy for people to collect monitoring information. Wireless communication technology and computer network technology are added to the security monitoring system to solve these problems. The main technical route of this thesis is wireless communication technology, general Packet Radio service) and single chip microcomputer technology. The application of sensor technology is involved in the intelligent terminal design of security monitoring system. This paper puts forward a scheme suitable for the school laboratory security monitoring system. Firstly, the development status of the existing wireless communication technology is briefly summarized, and the structure of the whole paper is put forward. Then it introduces the hardware used in the design of monitoring system, the characteristics and application of MCU AT89S52 / GPRS communication module SIM300C and so on. Finally, a remote wireless security monitoring system based on GPRS module of SIMCOM company and single chip microcomputer is designed. Serial port. The GPRS communication module SIM300C is driven by single chip computer (AT89S52), and the connection between SIM300C and Internet is established through the GPRS wireless communication network. The security monitoring center connects the Internet to receive the corresponding security monitoring information, and the reliable data wireless communication between the security monitoring center and the intelligent terminal of the monitoring and collecting equipment in the laboratory can be realized. This system is a set of security, hidden trouble detection and power convenience control of the laboratory monitoring system. Among them, the most important role of the anti-theft system is to improve the crime difficulty of thieves, and inform the experimenter in time. And has a certain deterrent and deterrence capacity; The main purpose of hidden trouble detection is to detect the potential danger in advance so that the experimenter can take precautions in time, eliminate the hidden danger and prevent unnecessary accidents. Power supply convenience control as long as the computer controls the entire laboratory system of the power supply on-time, or special cases of power failure, and can use short message to notify the relevant personnel.
