摘　　要：在中小化工企业的生产装置中，测控系统仍沿用分体式单元组合仪表来实现，其系统技术落后，亟待进行技术改造。为此，以８７Ｃ５５２单片机作为核心部件研制了一种新型多功能测控仪表，较好地满足了对测控系统进行低成本技术改造的需要。详细阐述了仪表的硬件特点、软件设计方法，并提出了提高仪表抗干扰性能的有效方法。It is well known that measurement-controlling system on the production facility of many mid-small chemical industry is processed by using split or unit-organization instruments, and the system is fall behind modern technology. For this purpose,a new type of Multifunction instrument was developed by using 87C552 single-chip processor as main component to be satisfied for reforming the system in low-cost.The paper introduces the characteristic of hardware and the design procedures of software ,and offers an effective methed of modifying characteristic of antijamming.
