本文介绍一种精密液压自动发生系统。该系统采用闭环负反馈控制、应用步进电机带动活塞压力泵作执行机构．采用０．０５级标准压力表作测量装置、应用单片机进行人工智能控制。系统满足了快速性、没有压力过冲、又有较高精度的要求。该系统研制成功不仅为压力自动检定提供了精密标准压力源。对于其它要求精密压力的场合也有应用价值。
This article describes a precision hydraulic automatic generation system. The system uses closed-loop negative feedback control, the application of stepper motor driven piston pressure pump for implementing agencies. Using 0.05 standard pressure gauge as measuring device, the application of single-chip artificial intelligence control. System to meet the rapidity, no pressure overshoot, but also a higher accuracy requirements. The successful development of the system not only provides a precise standard pressure source for pressure automatic verification. For other applications require precise pressure of the occasion also has application value.
