Study And Design Of Intelligent Pressure Measurement System

With the development of micro-electronical technology and information technology, automatic measurement technology has been one of the most important popular technologies in some developed countries. Now in many areas such as industry, agriculture, national defense, transportation, medical treatment, scientific research, measurement technology have been effecting more and more, measurement equipments can transmit many useful information continually like nerve and sense organ. Especially automatic measurement, alarm and control of pressure parameter have got a lot of attention. Although the research and development in this area has received some achievements recently, it still cannot meet the actual requirements, especially low power-consuming multiplex measurement technology needs to be developed urgently.The article does a deep research on the theory and application of intelligent pressure measurement system, comes up with a new structure of intelligent pressure measurement system, and designs completely on its intelligent functions, hardware and intelligent software. Meanwhile, considering universality, applicability and flexibility of the system application, many communication interface circuits is configured in the system, which can make the system more especial.Many simulative and digital peripheral modules are integrated in a high compositive powerful-functioned new SCM MSC1211Y4, which is used in the system to control and it has strong data processing capacity.The paper finished a complete intelligent software design, it makes the whole measurement system more intellectualized and realizes automatic plus control, temperature compensate, auto-collate, etc. For assuring the stability and reliability of the system, the calculating method of temperature compensate is figured out, and anti-jamming designs of hardware, PCB and software is made in the measurement system.The software was programmed in C language, which makes the software more readable. Modularization design is used in the software, which is easy to program and debug.The characteristics of the research are small cubage, low cost, low power- consuming, high reliability, fast reaction speed, high intelligentized level, etc., which can be used in many areas widely.
