Measuring And Control System To Fuel Test Bed

What this topic studies is a computer testing system for a fuel oil pressure testing platform, this testing system is used for the examinations of the physical quantity correlated to the estimating production. The high-speed signals of the intrance and out pressures of the fuel oil valve, the value of the coil electric current and voltage, are requested to be catches by the testing system, and also its waves are requested to be demonstrated. So that the workers can make a judgment to the product performance.The function of the testing system is divided into four stature functions module: The pressure control function module, Switch volume control function module, the flow measurement function module and the data acquisition function module. In the hardware realization aspect, the PC machine for Industrial, intelligence data acquisition card and'PLC compose a whole part. The development aspect of the system has used the many kinds of softwares, such as kingview software, Visual Basic6.0 and STEP7-Micro/WIN32 programming software. The c kingview software has the multitudinous merit, like the contact surface manufacture is easy, configurating simply and Convenient re-development and so on, but it insufficiently is high in the speed of the data acquisition. In order to make up the kingview software in the high speed data gathering aspect insufficiency, used the higher order language to program realizes high speed data acquisition. This system isnovelty or creativity in the data acquisition aspect.The realization of the testing system , has improved the precision of quality testing of the products , has improved efficiency of measuring , have made certain contribution for the Company.
