Description

Technical Field

[0001] The utility model belongs to the technical field of detecting fluid flow rate, and in particular relates to a non-contact and continuously measurable integrated flow monitoring device, which is used for measuring flow rate, water level and flow rate. Background Art

[0002] In some areas with abnormal rainfall, floods have a great impact on local residents, causing casualties, house collapse, traffic interruption and other serious consequences. In some underground coal mining faces, water companies, and sewage treatment plants, drainage system failures often occur. If the failure is not discovered in time, it will bring immeasurable losses. Flow meters can play a significant role in these areas and companies, and can feed back the water flow of rivers, lakes and drainage channels to the staff, so that protective measures can be taken more timely to reduce the losses caused by disasters.

[0003] The existing traditional contact flowmeter is affected by temperature, humidity, pressure, wind or other environmental conditions, sewage corrosion, sediment, etc., and has weak anti-interference ability; it needs to be in contact with the water body, and impurities or floating objects in the water body can easily cover the probe, and it is corroded by water, which affects the measurement accuracy or sensor failure. It cannot be applied to many rivers and lakes in my country with complex geographical environments. In the face of torrents, it is impossible to monitor the subtle changes in the river flow rate before the torrent arrives, resulting in the staff being unable to accurately predict the scope and size of the flood. At the same time, the maintenance of traditional contact flowmeters is relatively complicated and difficult, and the economic practicality is poor. Moreover, if traditional contact flowmeters are used, data collection and statistics are extremely inconvenient, and remote viewing of data terminals cannot be realized, and timely warning of emergencies cannot be provided.

[0028] In order to better explain the present invention and facilitate understanding, the technical scheme and effects of the present invention are described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, a non-contact and continuously measurable integrated flow monitoring device includes a monitoring pole 6, which is vertically fixed to the bank of the channel by screws through a ground cage for the installation of other devices. A lightning rod 3 is fixed on the top of the monitoring pole 6, and a lightning protection grounding grid 7 is laid underground to protect the monitoring equipment. A solar panel 4 is installed on the monitoring pole 6 and fixed under the lightning rod 3 by a stainless steel tie for energy transmission to provide electrical energy for the entire flow measuring device. An instrument box 5 is provided on the monitoring pole 6 and is installed under the solar panel 4 by a stainless steel tie for placing an adapter 9 and a battery 8. The battery 8 is placed in the instrument box 5 and electrically connected to the solar panel 4 for storing the electrical energy transmitted by the solar panel 4. After the solar panel 4 is connected to the battery 8, the battery 8 is directly connected to the adapter 9 and the radar flowmeter 1 respectively to provide electrical energy for both.

[0030] A cantilevered measuring rod 2 is installed on the monitoring pole 6 for installing the radar flowmeter 1; the measuring rod 2 is fixed to the monitoring pole 6 by a U-shaped buckle, and the plane where the end of the measuring rod 2 is located is located in the middle of the channel. The radar flowmeter 1 is fixed to the end of the measuring rod 2 and is electrically connected to the adapter 9 to measure the measuring liquid in the channel.

[0031] The solar panel 4 is fixed on the monitoring pole 6 to ensure the power supply of the adapter 9 and the radar flowmeter 1; the input end of the battery 8 is connected to the solar panel 4 to store power, and the output end is connected to the radar flowmeter 1 and the adapter 9 to provide power for both. Further, the radar flowmeter 1 is used to measure and receive water flow data, measure the water level and flow rate, and obtain the result flow data A according to the formula: instantaneous flow = average flow rate × flow cross-sectional area × correction coefficient, and then transmit the water flow data to the adapter 9 through the transmission line. The average flow rate and flow cross-sectional area are obtained by the radar flowmeter, and the correction coefficient is calculated based on the standard value obtained in the actual measurement environment.

[0032] The non-contact and continuously measurable integrated flow monitoring device also includes a control system, which includes a display and a MixIOT system. The display displays the measured open channel data in the form of a large data screen in the form of a chart. The MixIOT system is a software platform that uses collaborative filtering algorithms, CART decision tree algorithms, hash mapping theory, and data analysis models for multi-source heterogeneous data fusion to perform data statistics and storage, and compares the instantaneous flow and average flow rate transmitted to the MixIOT system by the radar flowmeter with the pre-set flow rate or flow standard value, and outputs different results in the face of different data situations. The MixIOT system is connected to the adapter 9 and the display. The adapter 9 establishes communication with the radar flowmeter 1 through the MoudbusRTU protocol to collect the required data. The adapter 9 converts the collected data into data in the MQTT format and transmits the data with the MixIOT platform through the MQTT protocol. The MixIOT system compares the data and controls the alarm program switch, and the display displays the water level changes and flow rate of the detection point in real time. The adapter model used in this embodiment is APRUS AX 6213C1, and the programming of the adapter is as follows:

[0035] The MixIOT system adopts existing technology. The MixIOT system undertakes tasks including IoT data reception, command issuance, data storage, data processing and data application interface, and the applications in the platform include terminal management, statistical calculation, offline data, object management, automatic reporting, etc. The MixIOT system is provided with a water body data input terminal and a result data output terminal. The water body data input terminal is connected to an adapter, which is used to input the water body data collected by the radar flow meter into the MixIOT system to provide real-time and accurate water body data; the result data output terminal is connected to a terminal display, which is used for the output and expression of the result flow data A to ensure the intuitive expression of the flow measurement results.

[0036] When the MixIOT system outputs the result flow data A to the display, the following comparison is performed at the same time: if A is greater than the set flow rate or flow rate standard, the alarm program is controlled to display the words "abnormal flow point" on the display; if A is less than the set flow rate or flow rate standard, the alarm program is kept in a static state. In this way, flow measurement and early warning are achieved. The utility model can realize remote monitoring functions, improve work efficiency and safety, and can efficiently monitor the real-time water level changes, flow rate and flow rate of the flow measurement point.

[0039] S2, place the battery 8 and the adapter 9 in the instrument box 5, the solar panel 4 collects solar energy and converts it into electrical energy and stores it in the battery 8, the battery 8 provides electrical energy for the radar flow meter 1 and the adapter 9, and supports the normal operation of the radar flow meter 1 and the adapter 9.

[0040] S3, radar flowmeter 1 measures water flow data, water level and flow rate, and obtains the result flow data A according to the formula: instantaneous flow = average flow rate × flow cross-sectional area × correction coefficient, and then transmits the water flow data to adapter 9 through the transmission line. The average flow rate and flow cross-sectional area are obtained by the radar flowmeter, and the correction coefficient is calculated based on the standard value obtained from the actual measurement environment. Adapter 9 establishes communication with radar flowmeter 1 through the Moudbus RTU protocol to collect the required data. Adapter 9 will convert the collected data into MQTT format data, and transmit data with the mixiot platform through the MQTT protocol.

[0041] S4, MixIOT system receives data, and MixIOT system compares the data and controls the alarm program switch, and the display shows the water level change and flow rate of the detection point in real time. MixIOT system finally displays the specific data on the display, and compares the data at the same time. If the result data A is greater than the set flow rate or flow standard value, the alarm program is controlled to display the words "abnormal flow point" on the display. If A is less than the set flow rate or flow standard, the alarm program remains in a static state. At this time, the flow measurement data has been completed.
