在内置式驱动活塞阀3上安装有传感器，包括安装在内置式驱动活塞阀3表面的振动传感器312、噪音传感器313，安装在内置式驱动活塞阀3内的压力传感器314、流量传感器315。具体地，振动传感器和噪音传感器的采集频率为0.2～1Hz，压力传感器的采集频率为10～100Hz，流量传感器的采集频率为1～10Hz，传感器可配置不同的采集频率。数据采集控制装置5与各传感器相连，通过智能RTU系统进行传感器数据采集，传输，远程控制内置式驱动活塞阀3。
本实施例中的无轴发电机2包括定子21、转子22、桨叶23和压盖24，定子21和转子22设置在管道1内，转子22与桨叶23为一体化设计，取消了中心轴，无轴发电机2整体采用钛合金螺栓联结，便于各种环境现场分散式拆装。定子21外壁与管道1固定连接；转子22包括开槽圆环221、永磁体222，开槽圆环221设置在桨叶23外侧，开槽圆环221的凹槽内交替放置极性不同的永磁体222，在无轴发电机2与管道1的连接处设置有压盖24。
内置式驱动活塞阀3包括阀体301、鼠笼304、阀座305和活塞302，阀座305设于阀体301末端，活塞302与鼠笼304之间设有连接盘303，阀体301内部具有容纳空间用于安装驱动装置310，驱动装置310与连接盘303之间通过连接板308连接，由驱动装置310带动活塞302沿内置式驱动活塞阀3中心轴线前后移动。
连接盘303上具有多处镂空，只需起到连接活塞302与鼠笼304的作用即可，镂空可减轻连接盘303本身重量，降低其加工工艺难度，同时也降低其制作成本。活塞302与鼠笼304均具有法兰端面且两法兰端面贴合，连接盘303通过螺栓与该两法兰端面紧固连接。本实施例中在整流短管4内设置有多根整流小孔，多根整流小孔阵列呈平板或蜂窝状结构且焊接成一体，整流短管4安装在无轴发电机2后方，对通过无轴发电机2的水流整流，调整流态，减少对内置式驱动活塞阀3的影响。
阀体301内部安装有闷盖307，闷盖307封闭端呈弧面结构，阀座口部设有阀座密封圈306，活塞口部设有活塞密封圈，阀体表面安装有控制盒316，控制盒316上设有穿线管311。
本实施例中，数据采集控制装置5通过RS485总线与内置式驱动活塞3阀相连，并在处理器内置嵌入式控制算法对内置式驱动活塞阀3进行调节，Modbus、IEC104等常见水利行业协议进行传输，可以兼容多种不同信号形式传输，支持多种通信方式。
具体地，在数据采集控制装置5中处理器集成了水力模型、设备特性曲线的仿真运行数据，构建策略知识库。各个传感器实时采集传输数据到数据采集控制装置5中，由处理器处理，当采集到的数据超出了设定范围最大值，处理器做出该器件故障的判定，数据采集控制装置5发出报警信号，通知工作人员及时处理，准确控制阀门运行安全性。
在离线状态下，各个传感器实时采集传输数据到数据采集控制装置5中，采集到的数据与设定在处理器中的设定值范围对比，如没有超出设定范围最小值，则将该数据记录存储在存储芯片中，如超出了设定范围但没有超过设定范围最大值，在记录到储存芯片的同时，由处理器里集成的水力模型数据会自动根据当前数据，分析整理出合理的方案，并且通过数据采集装置传输至器件动作，使采集到的数据控制在合理范围。
在数据采集控制装置5的处理器中集成有阀门常见类故障与阀门运行特征数据，构建健康诊断知识库，能快速、准确判断阀门健康度。当超过设定值范围时，处理器自动分析模型数据，得出针对当前工况的最优处理方案，通过I/O接口传送至驱动装置，驱动装置310依照方案中指令执行。
本实施例中，智能RTU系统集成仿真模型的控制策略，实时采集阀门运行状态和水力参数，并通过PID技术对内置式驱动活塞阀进行智能调节和分布式控制。具体地，智能RTU采用ARM V8架构的CPU Cortex-A72，并配以4G以上的内存，集成了无轴发电机自供电调流调压智能装备KV曲线，作为日常运行校核运行状态和故障等健康度判断的依据，并不断校核；接收并集成上层平台完成的迭代了KV曲线的瞬态水力模型的分析数据，在目标控制和策略控制时，作为控制过程安全校核的依据，并对控制后的效果进行评估；在智能RTU中构建了策略库，将经过安全校核的经验控制策略，和经过瞬态安全仿真的控制策略，集中存储作为策略库；在日常控制过程中汲取非策略库中的控制模式，并更新策略库。
本智能内置式驱动活塞阀集成现代物联网技术，实现可实时监控内置式驱动活塞阀中流量、压力、动作位置等信息，存储并传输数据，根据阀门中不同的情况作出相应的调节，远程控制内置式驱动活塞阀，抑制故障的发生，提升阀门和系统的安全性、可靠性。
显然，上述实施例仅仅是为清楚地说明本发明的技术方案所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
