The course of curriculum design is a kind of basic quality training of students is better form, can through the curriculum design to strengthen the students practical ability, practical ability and learning ability. Combine learning theoretical knowledge and actual situation, thus make the pressure measurement and control system design. 1 this topic. The rapid economic development of today makes scientific, intelligent construction of city gradually. Integrated with various features of fusion, now become the mainstream of technology development trend. Pressure measurement and control system is an important measurement in industrial production process automation equipment, can be used to measure pressure, liquid level of engineering parameters. This paper introduces a kind of pressure measurement and control system based on 8086 microprocessor, system operation is simple, high degree of automation, extension, convenient and has a good ability of human-computer interaction. Through the experiment,
