摘 要：根据黄河流域引黄灌区引水多泥沙、易淤积的特点，采用电子、自动控制、物联通信、防盗防破坏等关键技术研发了适合手动闸门量水控制的手改电闸门测控一体化系统。系统中设计了太阳能供电装置，将手动闸门改造成电动闸门进行控制，闸门下游设计安装超声波水位计测量闸门下游标准堰槽处的水位及流量，并作為反馈值反馈给闸门控制单元，通过内置控制算法程序驱动闸门启闭机实现闸门闸位、水位及过闸流量的动态控制;系统上位应用管理软件引入智能PID控制算法，实现了系统参数自动调节和稳定运行。系统在引黄灌区开展应用，解决了引黄灌区手动闸门长期靠人工计量与控制造成的测控精度低、实时性差问题，实现了手改电闸门的水位、闸位及流量的远程自动控制。

Abstract： According to the characteristics of sediment and siltation in the irrigation area of the Yellow River basin， the integrated monitoring and control system of the hand-changed electric gate was developed by using the key technologies of electronics， automatic control， communication between objects， anti-theft and anti-destruction. Solar power supply system was designed in the system. The manual gate was transformed into an electric gate for control. An indirect ultrasonic water level meter was installed downstream of the gate to measure the water level and flowed at the standard weir channel downstream of the gate. The feedback value was fed back to the gate control unit and the gate was driven by the built-in control algorithm program. The hoist realized the dynamic control balance of gate level， water level and flowed through the gate; the upper application management software of the system introduced the second-order system and the intelligent PID control algorithm with self-learning function of self-learning PID， and explored and designed the application management software suitable for the integrated monitoring and control system of the hand-changed gate. The system had been applied in the irrigation area of the Yellow River diversion. It had solved the old and difficult problems of the manual gate in the irrigation area of the Yellow River diversion， such as long-term manual measurement and control， low measurement and control and poor real-time performance， and had realized the remote automatic control of the water level， gate level and flow of the manual gate.

Key words： manual to electric gate; integration technology of measurement and control; Yellow River irrigation area

黄河流域有许多大型的引黄灌区，历来是我国的粮食主产地。但是黄河水自古以来就有泥沙含量高、淤积严重等特点，采用传统的投入式等直接量测水方式，很难保证量测的精度，不适合水量的计量和监控;而且手动闸门地处野外，点多面广，在供电、通信、防盜防破坏等方面存在一系列问题。长期以来，引黄灌区手动闸门的量测水方式较为落后，精度低、实时性差，难以达到水资源精细化管理的要求。
