A Scrutiny System In The Oil Field Important Place Safety On Guard

A practical engineering item about safety keep away from theft and fire in a oil field is discussed. The scrutiny system designing theory is discussed in this paper. It include the function of the system, structure, selecting parts of an apparatus, fitting, regulating and preserve methods and so on.A superior-slave structure is adopted in this system. The superior system adopt industry control computer. It works stabilize, safety credibility, price lows. Micro-soft Windows OS system is selected. VB programming software is uses. It has friendly visit serial convenience advantage on the Visual Basic. Its function can satisfy Programming condition for the apply system. The superior's function is set up defenses and cancel defenses on area in part time. The alarm record and managing records are printed.The three parts are mated in slave system:The first slave system is locale coders and data collection system. This class system is mated for more than one. Its main function is collection sensor's state in guard against area. if some alarm case is happen there, the locale slave system report to superior system. It accepts command from superior system and control the defenses, cancel defenses, open lamp, alarm and so on.The second slave system is video frequency quadrature switch system. The main function is executing from superior system. It can control display video frequency switch. This system is consisted of 8090 CPU mainly.The third slave system is main control platform. This system is consisted of 8051 CPU mainly. When superior system transmit the control power to this slave system, it will control locale coders and data collection system by keyboard on platform.The superior system communicates with slave system through serial port.Now, the scrutiny system in a oil field important place safety on guard having used in locale safety.
