Burglar Alarm System Of Oil Storage Tanks Base On Wireless Network

In recent years, the development of wireless communication technology is a big role in promoting all industries, especially in the petrochemical industry. Petrochemical industry, there is wide geographical, characteristics of higher risk, using wireless communication technology can significantly reduce the connection between field devices, improve system flexibility and security.With the steadily rising international oil prices, some lawless elements sights on the crude oil, by stealing crude oil to reap economic benefits, the breeding of this phenomenon to the petrochemical enterprise safety management brought a lot of hidden dangers, caused significant economic losses to the enterprise, how to effectively suppress this phenomenon became a petrochemical producers have to face problems. In this paper, because most of the oil storage tanks at the field site is unattended and do not have any oil security monitoring equipment, storage tanks Stolen unable to detect and stop the phenomenon, has designed a solution. The system uses the latest generation of ARM, CortexTM-M3 core 32-bit processor STM32F103, support for multiple data acquisition methods(current, voltage, RS485, CAN), through a variety of wireless data transmission methods(GPRS, radio stations, ZIGBEE) transfer data to the center. Support oil storage burglar alarm function, when happen oil stolen, the system give alarm by voice and SMS, in cooperation with wireless networks and data centers software, users can remotely monitor the stolen phenomenon.System software design using object-oriented design and standard user interface, according to software function, the system software is divided into driver layer, middle layer and the user layer, drives layer is a collection of drivers for hardware modules, middle layer is to provide a common operation for collection of user, such as the middle layer FatFS file system provide to read and write file user-level access services, user layer is a collection of user operation interface, by use of user-level services to provide functionality required for users, the system have Shell service, MODBUS service, parameter configuration service, system log service, SMS service, communication service, oil security services.The last part of paper describes the testing system, including the development test and field testing, detail the system test environment and test results, through extensive testing of the system, verify the effectiveness of the system design, reliability and security, through the field test, the system well positioned to meet petrochemical requirements, effectively reducing the enterprises economic losses due to Stolen.
