Research Of Performance Of Temperature Transducer Used In Car Realm Test System

With the extensive application of temperature transducer used in Automobile, especially used as the information source of car electronics control system, the research and technical improvement of temperature transducer seem to be particularly for importance. So that is in car realm, real time and the high accuracy acquires the temperature is the key to go deep into investigative in Automobile. Performance of temperature transducer used in car realm test system embodies the technology of computer control, information detect. The research for this system to pass real time detect the temperature transducer with temperature and resistance, and draw the characteristic curve of the each temperature according to the parameter. The design of this system can improve not only the temperature transducer technique, but also provide with evidental documents to realize the test of all kinds of parameters make use of the computer, and the technology of computer control the extensive application in car realm.Firstly we study the construction of the system, it is the basis to realize the measure and control. In this system we design the electric elevator, gasoline tank and the circulatory system to examine the system, discuss how to design and how to manufacture them, and proceed to analyse the examination accuracy.The control system is the core for test-bed, for this, this text design the control system of the electric elevator and the control system of the temperature. To the electric elevator, we use the auto and manual method of control, combine control principle of two kinds of methods, it provides guarantee for whole line of the system. While in addition to measure the temperature and the resistance, the control system of the temperature still controls process, regulate and control temperature etc. In the control system of the temperature here, we introduce a kind of fuzzy PID control technique, which resolving the temperature of the hard solution in method in other control the super adjusting the problem goodly, making whole on trial can smoothly progress, increases the temperature control the accuracy.Make use of the interface technique of computer and hardware, apply Visual Basic language, establish the customer interface on the computer screen, push the control button, realize to control all procedures and the whole system. Namely we realize to collect the data of temperature transducer, enactment of the temperature, the auto control of the electric elevator and use the picture box of VB to hatch so that we can compare, analyze and research.After debugging and operating dynamic character parameter of the test system, we analyze the error of the experimental result and prove that experiment data and curves are in the range of permission. The design of the whole system can reduce to test manpower for needing devotion consumedly with time, the system circulates dependable. The design of the whole system is reasonable and successive, and can proceed the practical stage completely. It is of great importance to study how improve and increase the technique of temperature transducer.
