Detailed ways

The present invention will be further described below in conjunction with specific embodiments.

Example 1

Pump pipe valve system with intelligent remote monitoring, early warning and control terminal, intelligent remote monitoring, early warning and control terminal, composed of micro-hydropower control board and data acquisition board; data acquisition board includes processor, on-board memory chip, Isolated interface, digital input interface, digital output interface, analog input interface and several function expansion sockets, on-board memory chip, isolated interface, digital input interface, digital output interface, analog input interface, expansion socket are respectively in the processor The micro-hydro power generation control board is connected with the data acquisition board through the bus.

The equipment and devices connected to the intelligent remote monitoring, early warning and control terminal in each pump station and valve room collect data in real time and transmit it to the intelligent remote monitoring and early warning and control terminal. The processor compares the real-time parameters with the set parameters, and then There is no action within the normal range. If an abnormality is found, the corresponding alarm signal will be triggered, and the abnormal parameters will be transmitted to the upper-layer monitoring center. The upper-layer network will analyze the most suitable solution and transmit it back to the intelligent remote monitoring, early warning and control terminal. Remote monitoring and early warning and control terminal control the corresponding device action until the alarm signal disappears.

As shown in Figure 1, after the water in the pump tube valve system is processed by the pump station, it is transported to the destination through the pipeline. In the figure, it passes through 4 water distribution ports, and each water distribution port is controlled by a water distribution port valve chamber to control the flow of the water flow branch. size. Each water outlet valve chamber is equipped with different devices according to the specific situation, terrain and environment. As shown in Figure 2, the system of a certain water outlet valve room is configured with 2 groups of valves. The 2 front and rear maintenance valves of each group are maintenance butterfly valves. Sensing devices such as pressure sensors and noise and vibration sensors of the main valve. As shown in Figure 3, the upper information network is connected to the monitoring center by the intelligent remote monitoring, early warning and control terminal through switches or routers, and the upper platform of the monitoring center has a complete set of application system deployment, connecting the control network of each pumping station and water outlet; The control network of each pump station and water outlet on the lower layer is also deployed by switches or routers, and the intelligent remote monitoring, early warning and control terminals are connected to various actuators and sensing devices through switches or routers.

As shown in Figure 3, taking the valve chamber control network as an example, the intelligent remote monitoring, early warning and control terminal is connected to multiple devices through the RS485 bus. , When the valve cannot switch the valve through the normal torque, and the valve cannot read the flat pressure signal, it means that the valve is faulty and cannot operate normally. At this time, the fault alarm signal is sent through the intelligent remote monitoring, early warning and control terminal, and the relevant data is transmitted to the monitoring center system platform. The system platform obtains the optimal control strategy through big data analysis, and returns to the intelligent remote monitoring, early warning and control terminal. The remote monitoring, early warning and control terminal is transmitted to the execution device through the bus, and the corresponding actions in the control strategy are made. After the fault is eliminated, the system returns to normal and the alarm signal disappears.

Example 2

Different from Embodiment 1, Embodiment 2 is distributed control of multiple intelligent remote monitoring, early warning and control terminals. In long-distance water delivery projects, in the valve chambers of multiple water outlets in the pipeline, to realize the pressure and flow control of the system for the safe operation of the pipeline, not only the intelligent remote monitoring, early warning and control terminal is required, but also the joint control of multiple units is required. In the distributed deployment network, master-slave deployment is implemented between intelligent remote monitoring and early warning and control terminals, and the real-time data collected according to actual working conditions is aggregated, analyzed and controlled in a unified manner. As shown in Figure 1, for example, when the pool of a certain No. 2 water outlet is full and the water level of the pool exceeds the high water level, an alarm signal will be sent. Control strategy to each water outlet. At the No. 1 water distribution port, the valve will be controlled to be appropriately closed, so that the outflow will become smaller and not exceed the high water level line of the No. 1 water distribution port. When the water level of the water outlet pool drops, when the water level of the No. 2 pool does not exceed the high water level line, the No. 3 water level remains within the normal water level range, the alarm signal disappears, the system returns to normal, and the indoor valves of each water outlet valve return to the level before the control strategy was executed. status.
