[0015] Embodiments of the present invention relate to a buried pipe network control device, such as figure 1 As shown, including the inlet tube 1, the cartridge 2, the overhaul hole 3, the inlet pressure sensor 4, the flow regulator 5, the data collector 6, the controller 7, the flow sensor 8, the outlet pressure sensor 9, and the outlet tube 10.

[0016] Further, the inlet tube 1 is disposed on one side of the cylinder 2, the outlet tube 10 is disposed on the other side of the cylinder 2, and the inlet tube 1 is connected to the outlet tube 10, the inlet tube 1. The inlet pressure sensor 4 is provided with an inlet pressure sensor 4 in the inlet pipe 1, and an outlet pressure sensor 9 is provided on the inlet pipe 1, and an outlet pressure sensor 9 is provided. The inlet tube 1 and an outlet tube. 10 The connection is provided with a flow regulator 5, and the flow regulator 5 is disposed between the inlet pressure sensor 4 and the outlet pressure sensor 9, and a flow sensor 8 is provided between the flow regulator 5 and the outlet pressure sensor 9. The top of the cylinder 2 is opened, which is easy to repair and maintenance; the inlet pressure sensor 4, the flow regulator 5, the data collector 6, the controller 7, the flow sensor 8, and the outlet pressure sensor 9. The accommodation is integrated within the cylindrical body 2; the data collector 6 and the controller 7 are integrated; the data collector 6 is configured to collect the pressure signal of the inlet pressure sensor 4, the pressure signal of the outlet pressure sensor 9 The flow signal of the flow sensor 8; the controller 7 is configured to adjust the overcurrent area of ​​the flow regulator 5, thereby changing traffic and pressure.

[0017] Further, the buried pipe network control device in the present embodiment is completed in the factory, and the overall transportation to the installation site, digging pits directly connected to the pipeline buried underground, and the pipeline is connected to the mud backfill, pipe network measurement and control The device is buried below the ground and does not occupy the ground space.

[0018] Further, the remote data transmission module is provided in the controller 7, which is configured to transmit the pressure signal and flow signal collected by the data collector 6 to the scheduling control center or the cloud. By the scheduling control center or the cloud understands the pressure and flow state information of the pipe network; the controller 7 is also provided with an output pressure model in accordance with the flow rate.

[0019] During the pipe network water supply, the controller 7 transmits the signal of the inlet pressure sensor 4, the flow sensor 8, and the outlet pressure sensor 9 through the remote data transmission module to the scheduling control center, and realizes the monitoring network operation status parameters. The following pairing network The situation encountered during the water supply process is specified:

[0020] When in the water supply trough, the flow rate in the pipe network, the loss of the pipe network is reduced, the remaining pressure in the pipe network is too large, the end of the pipe network is elevated, so it is necessary to step down, on the one hand, the controller 7 passes remotely The data transmission module transmits the pressure signal to the dispatch control center, the scheduling control center reduces the output pressure of the front end booster system according to the pressure signal of the inlet pressure sensor 4 acquired by the data collector 6, and can effectively reduce the pipe network boost system. Energy consumption; on the other hand, the controller 7 transmits the control signal to the flow regulator 5, that is, the overcurrent area of ​​the flow regulator 5 is reduced by the controller 7, so that the output pressure of the front end booster system and the output The pressure value of the pressure model is in the range of preset error.

[0021] When in the peak water supply peak, the traffic in the pipe network is large, the pressure is insufficient in the pipe network. On the one hand, the controller 7 transmits the pressure signal to the dispatch control center by the remote data transmission module, and the scheduling control center is collected according to the data collector 6. The pressure signal of the inlet pressure sensor 4, raises the output pressure of the front end booster system; on the other hand, the controller 7 transmits the control signal to the flow regulator 5, i.e., by the controller 7 to increase the traffic adjustment. The overcurrent area of ​​the device 5 makes the output pressure of the front end booster system and the pressure value of the output pressure model in the preset error range.

[0022] When in the normal water supply period, the flow in the pipe network is moderate, and some of the time stress in the pipe network, the partial pressure is insufficient, the controller 7 transmits the control signal to the flow regulator 5, adjust the overcurrent area of ​​the flow regulator 5, and make the front end The output pressure of the booster system and the pressure value of the output pressure model are within the preset error range, ensuring stable user-end pressure.

[0023] Further, the output pressure model can vary depending on the change of the water supply scene, and the output pressure model can vary depending on the factors such as the flow rate, and the flow requirements, and the flow rate change, the output pressure model can vary with the water supply scene. The supply demand for commercial buildings changes over time; in addition, the output pressure model can be customized.

[0024] From this, it can be seen that the present invention can solve the operating state monitoring of the pipe network, reduce the risk of pipe network explosion tube, and reduce the energy consumption of the pipe network water supply boost system.
