[0002] In order to eliminate the phenomena of illegal discharge and leakage and ensure the efficient operation of drainage pipe networks and sewage treatment facilities, it is urgent to build a real-time, efficient, low-cost and easy-to-deploy sewage pipe network flow rate online monitoring system. At present, the flow rate measurement mainly adopts the Doppler flow rate measurement principle, radar flow rate measurement, electromagnetic flow rate and other principles. However, the complexity of the drainage pipe network working conditions makes the single measurement principle have certain limitations, so the measurement solution of integrated technology becomes very meaningful.

[0003] Existing drainage network detection usually adopts Doppler flow velocity measurement principle and electromagnetic flow velocity, but it only performs detection at a single location and cannot completely eliminate the phenomenon of illegal drainage and leakage. In order to ensure the orderly discharge of the drainage network, it is necessary to detect it as a whole. Therefore, a comprehensive drainage network flow velocity measurement system is proposed to solve the above-mentioned problems. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] In the embodiment, Figure 1-3 A comprehensive drainage network flow velocity measurement system is provided. The present invention includes a basic velocity measurement unit, which includes an information processing module, a main control module, a data collection module and a power supply module.

[0038] Main control module: provides basic functions for controlling data transmission and each module, as well as providing computing support for each module;

[0039] Information processing module: provides data storage and wireless transmission functions, and can also form a transmission network;

[0040] Data collection module: supported by Doppler flow acquisition module and electromagnetic flow acquisition module, which monitor water flow respectively;

[0041] Power supply module: provides data wired transmission and power supply functions;

[0042] There are multiple basic speed measurement units and they are set at pipeline nodes and branches, and multiple information processing modules are used to build a network through wireless transmission.

[0043] Among them, the main control module contains a control information storage module and a switch signal generating module. The control information storage module includes a normal information storage module and a test information storage module. The normal information storage module stores readable and writable speed measurement event intervals and speed measurement duration information, and the test information storage module stores read-only test duration information and speed measurement control information.

[0044] In the test state, the system runs as a whole, all internal components remain in working state, and continue to work for a set time. After the test process is completed, it is forced to sleep for a set time. The test results are fed back through the power supply module.

[0045] The switch signal generating module transmits the switch signal through the power supply module, and the switch signal generating module generates the switch signal according to the control information in the control information storage module.

[0046] The switch signal is generated according to the information in the normal information storage module. After the switch signal is generated, the corresponding switch signal is transmitted through the bus and controlled by the main control module.

[0047] Among them, the basic speed measuring unit at the pipeline node and the basic speed measuring unit at the branch are point-to-point connected through the information processing module, and the two adjacent basic speed measuring units at the pipeline node are bridged through the wireless transmission function.

[0048] Among them, the information processing module stores the speed measurement data, and the amount of data stored in the information processing module is controlled by the main control module. The information processing module in the basic speed measurement unit at the pipeline node simultaneously compares the data correctness.

[0049] When the data from the branch is transmitted to the main line, the main line compares the previous speed measurement information of the branch with the last transmitted information. If there is a difference, it means that packet loss has occurred. At this time, it is judged that the wireless transmission function of the basic speed measurement unit at this location is no longer reliable and requires maintenance.

[0050] Among them, the Doppler flow acquisition module and the electromagnetic flow acquisition module both include a detection data analysis module and a speed measuring probe. The detection data analysis module converts the signal of the speed measuring probe into an electrical signal and transmits it through the information processing module.

[0051] Among them, the power supply module includes a bus and a backup power storage module. The backup power storage module provides backup power for other modules. Multiple basic speed measurement units are connected through the bus, and the main control module, information processing module and power supply module are directly connected to the bus.

[0052] Through the bus connection, the aforementioned data comparison can also be combined with the bus data transmission for comparison. If errors still occur, it indicates that there is an abnormality in the line or the entire basic speed measurement unit, and maintenance is required.

[0053] Among them, it also includes control cloud and data relay terminals;

[0054] The data relay terminal is connected to the bus and transmits data to the control cloud via 5G signals;

[0055] The control cloud is used to store data and share it with other terminal devices through the cloud;

[0056] The information processing module stores the operation log, and the control cloud can directly read the operation log through the data relay terminal and bus.

[0057] Other terminal devices include network devices that can log in to the cloud, such as mobile phones. At the same time, the control data submitted by the network devices can be transmitted through the control cloud and data relay terminals, so that remote control can be performed through the network devices.

[0058] Among them, the basic speed measuring unit is based on a speed measuring device, which includes a device housing 1. The inside of the device housing 1 is fixed with a power supply 2, an electromagnetic flow velocity analysis device 3, a multipt flow velocity analysis device 4, a communication device 5, and a microprocessor 6. The inside of the device housing 1 is fixed with an electromagnetic flow velocity detection probe 7 and a multipt flow velocity detection probe 8 extending to the outside.

[0059] In particular, the entire shell 1 is made of ABS plastic, and the electromagnetic flow velocity detection probe 7 and the Dopt flow velocity detection probe 8 are fixed with fasteners. The device shell 1 is fixed by fasteners, which is convenient for subsequent disassembly and maintenance. The microprocessor 6 is also responsible for signal processing and control of various components, and the power supply 2 is connected to the bus.

[0060] Working principle:

[0061] Under normal conditions, the flow velocity at this location is detected by the electromagnetic flow velocity detection probe 7 and the Dopt flow velocity detection probe 8, and then the electromagnetic flow velocity analysis device 3 and the Dopt flow velocity analysis device 4 perform signal analysis to generate a flow velocity signal. At this time, the flow velocity signal can be processed by the microprocessor module 6 and then transmitted through the communication device 5 and the bus.

[0062] By detecting the flow rate at multiple branches and coordinating the flow rate detection at the nodes, the flow rate can be conveniently monitored uniformly. When abnormal discharge occurs, the flow rate anomaly can be directly traced back to the branch, and the abnormal point can be known.

[0063] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
