摘　　要：介绍一种基于STC单片机的正负压测漏系统。通过对现有气压测漏仪的研究,设计出能实现正负压综合检测的气动系统;以STC89C52RC单片机为核心控制单元,设计了测漏系统的控制部分;分析实验结果,得出检测过程符合泄漏规律的结论。因此该正负压测漏系统能够实现对密封件的检测。A new positive and negative pressure leak detection system based on STC microprocessor was introduced. By analyzing present pressure leak detector, the pneumatic system which could be applied in case of positive and negative pressure comprehensive testing was designed. By the STC89C52RC microprocessor as the core control unit, the control section of this leak detector was designed. The experimental results were analyzed, and the conclusion was that the leak detection process met the leak rules. So this system can be used to test seals.
