[0029] Embodiment 1

[0030] Figure 1 This is a structural block diagram of an agricultural and animal husbandry irrigation water meter monitoring system provided in the first embodiment of the present invention. This embodiment can be applied to the situation where a mechanical water meter in an agricultural and animal husbandry irrigation scene is remotely monitored online, such as Figure 1As shown, the agricultural and animal husbandry irrigation water meter monitoring system 100 includes: a mechanical water meter 110, an agricultural and animal husbandry irrigation water meter monitoring device 120 and an Internet of Things monitoring terminal 130; the mechanical water meter 110 is configured in the agricultural and animal husbandry irrigation area, the agricultural and animal husbandry irrigation area includes at least one mechanical water meter 110, and each mechanical water meter 110 is respectively installed with an agricultural and animal husbandry irrigation water meter monitoring device 120, and the agricultural and animal husbandry irrigation water meter monitoring device 120 is communicatively connected with the Internet of Things monitoring terminal 130;

[0031] The mechanical water meter 110 is configured to measure and display in real time the current water consumption of the associated mechanical and electrical well in the associated agricultural and pastoral irrigation area;

[0032] The agricultural and animal husbandry irrigation water meter monitoring device 120 is configured to collect water meter images and obtain water meter parameter information of the associated mechanical water meter 110, and package the water meter images and water meter parameter information and send them to the Internet of Things monitoring terminal 130;

[0033] The IoT monitoring terminal 130 is configured to parse the water meter image and water meter parameter information included in the received packaged data, obtain the real-time water volume reading information of the mechanical water meter 110 associated with the packaged data, and add the watermark information including the water meter parameter information to the water meter image for storage.

[0034] In a specific embodiment of the present invention, an agricultural and animal husbandry irrigation area refers to an area where an irrigation mode is used to ensure crop production, mainly through various agricultural water conservancy irrigation facilities to meet the needs of crops for water, regulate land temperature, humidity and soil air and nutrients, and improve land production capacity. Depending on the specific application scenario, an agricultural and animal husbandry irrigation area can be any area that uses an irrigation mode for crop production.

[0035] Correspondingly, a mechanical water meter refers to an instrument that can measure the amount of water used, and according to the use of water resources, the current amount of water used is recorded in real time, and the measured amount of water used is displayed on the dial of the instrument. Among them, any instrument that can realize the metering of water use can be applied to this embodiment, and the metering method and display method of the mechanical water meter are not limited. According to the irrigation needs, a plurality of electromechanical wells can be set in the agricultural and pastoral irrigation area, and the electromechanical wells supply water to different areas in the agricultural and pastoral irrigation area respectively to complete the irrigation of the agricultural and pastoral irrigation area. Correspondingly, in order to monitor the amount of water used, record the amount of irrigation water, and prevent excessive use of water, the mechanical water meters are also dispersedly set in the agricultural and pastoral irrigation area along with the distribution of electromechanical wells.

[0036] In this embodiment, the agricultural and animal husbandry irrigation water meter monitoring device refers to a monitoring device that integrates a macro camera, an image encoding unit, a fill light unit, a main control unit, a data storage unit, a wireless communication unit or a positioning unit. An agricultural and animal husbandry irrigation water meter monitoring device is installed in each mechanical water meter in the agricultural and animal husbandry irrigation area to form a new intelligent water meter. Therefore, when it is necessary to monitor the water intake and withdrawal amount of the agricultural and animal husbandry irrigation area online, the agricultural and animal husbandry irrigation water meter monitoring device is used to collect images and obtain water meter parameter information of the corresponding mechanical water meter to be monitored, collect water meter record information in a visual manner, and upload the collected data and images in a minimized manner, so as to achieve a complete record of the metering situation of the water meter. Among them, the water meter image includes a mechanical water meter water volume reading interface, and the water meter parameter information may include a unique identification code of the mechanical water meter, a timestamp when the initial water meter image is collected, the positioning information of the water meter, and the power information; wherein, the position information of the mechanical water meter can be collected in real time by the positioning unit, but since the position of the mechanical water meter is relatively fixed, the position coordinates of the mechanical water meter and the unique identification code of the mechanical water meter can also be pre-stored in the agricultural and animal husbandry irrigation water meter monitoring device to uniquely identify the collected water meter image.

[0037] In this embodiment, the Internet of Things monitoring terminal refers to a terminal that can remotely monitor the real-time water consumption online. It can receive the water meter image and water meter parameter information uploaded by the agricultural and animal husbandry irrigation water meter monitoring device, and use image recognition or deep learning algorithms to identify the water consumption reading in the water meter image, thereby obtaining the real-time water volume reading information of the mechanical water meter. Specifically, the Internet of Things monitoring terminal may include a cloud server and a cloud Internet of Things management platform. Among them, the cloud server is used to parse and process the received water meter image and water meter parameter information, and the cloud Internet of Things management platform is used to uniformly monitor and control the readings of each mechanical water meter in the agricultural and animal husbandry irrigation area.

[0038] Correspondingly, the IoT monitoring terminal can also send control instructions to the agricultural and animal husbandry irrigation water meter monitoring device in reverse to control the working status of the agricultural and animal husbandry irrigation water meter monitoring device and the mechanical water meter, such as controlling the power supply model of the agricultural and animal husbandry irrigation water meter monitoring device, the monitoring frequency of the image, and the valve status of the mechanical water meter.

[0039] Specifically, in the process of monitoring agricultural and animal husbandry irrigation water meters, the mechanical water meter measures the irrigation water consumption in real time and displays it on the dial of the mechanical water meter. The agricultural and animal husbandry irrigation water meter monitoring device collects images and data according to the configuration information, and obtains a water meter image with a clear picture and small data volume including the mechanical water meter water volume reading interface by taking a macro shot of the mechanical water meter after adjusting the illumination, and then packages the obtained mechanical water meter parameter information and the compressed and encoded water meter image together and uploads them to the Internet of Things monitoring terminal, so as to minimize the upload of the water meter image. Finally, the Internet of Things monitoring terminal obtains the real-time water volume reading information of the mechanical water meter by analyzing the water meter image. At the same time, in order to ensure the traceability and security of the data, watermark information including the water meter parameter information can also be added to the water meter image, and the Internet of Things monitoring terminal is responsible for the unified management of the water intake and usage information.

[0040] The technical solution of this embodiment uses an agricultural and animal husbandry irrigation water meter monitoring device to collect images of mechanical water meters, and uploads the acquired water meter parameter information and water meter images to the Internet of Things monitoring terminal, and reads and identifies the water meter images through the monitoring terminal to obtain real-time water volume reading information. The embodiment of the present invention installs an agricultural and animal husbandry irrigation water meter monitoring device for mechanical water meters, and combines the remote monitoring terminal to identify the water meter reading information, thereby realizing online monitoring of the water intake of mechanical water meters in agricultural and animal husbandry irrigation scenarios, reducing the use cost of equipment and improving the accuracy of data monitoring.

[0041] Embodiment 2

[0042] Based on the above-mentioned first embodiment, this embodiment provides a preferred implementation of an agricultural and animal husbandry irrigation water meter monitoring device, which can minimize the upload of macro-shot water meter images in agricultural and animal husbandry irrigation scenarios. Figure 2 The structural block diagram of the agricultural and animal husbandry irrigation water meter monitoring device provided in the second embodiment of the present invention is as follows: Figure 2 As shown, the agricultural and animal husbandry irrigation water meter monitoring device 120 includes: a water meter image acquisition module 121 and a main control module 122, and the water meter image acquisition module 121 is connected to the main control module 122 through a serial port; wherein the water meter image acquisition module 121 includes a macro camera 1211 and an image encoding unit 1212, and the image encoding unit 1212 is connected to the macro camera 1211; the main control module 122 includes a micro control unit 1221 and a wireless communication unit 1222, and the micro control unit 1221 is connected to the wireless communication unit 1222;

[0043] The macro camera 1211 is configured to perform macro photography of the associated mechanical water meter 110, obtain an initial water meter image including a water volume reading interface of the mechanical water meter, and send the initial water meter image to the image encoding unit 1212;

[0044] The image encoding unit 1212 compresses and encodes the received initial water meter image to obtain a compressed and encoded water meter image to be detected;

[0045] The micro control unit 1221 is configured to obtain water meter parameter information of the associated mechanical water meter 110, and pack the image of the water meter to be detected and the parameter information into a data packet;

[0046] The wireless communication unit 1222 sends a data packet to the IoT monitoring terminal 130 .

[0047] In a specific embodiment of the present invention, a water meter image acquisition module is used for the acquisition and encoding of water meter images, and may include a macro camera and an image encoding unit. The associated mechanical water meter refers to a mechanical water meter to be monitored that is equipped with a current agricultural and animal husbandry irrigation water meter monitoring device, and the current agricultural and animal husbandry irrigation water meter monitoring device is integrated in the mechanical water meter to be monitored. Among them, the macro camera can take ultra-close-up photos of the mechanical water meter to achieve close-up clear photography when the space of the mechanical water meter is limited; the image encoding unit is used to compress and encode the acquired initial water meter image to reduce the data volume of the water meter image, and convert the initial water meter image into the image encoding format required by the business.

[0048] For example, a high-definition low-light macro camera can use a small-sized CMOS sensor to ensure high-quality images, collect image data with lower resolution, such as 640×480 or 160×80, etc., and obtain a water meter image in JPG encoding format through an image encoding unit. In this way, the processing of the collected image can be minimized without affecting image recognition, thereby saving the limited storage space occupied in the agricultural and animal husbandry irrigation water meter monitoring device, reducing the traffic consumption and cost when uploading data, improving the data upload speed, and ensuring the real-time nature of online monitoring.

[0049] In this embodiment, the main control module is connected to the water meter image acquisition module via a serial port. The main control module is used to upload the packaged water meter image and water meter parameter information for processing, and may include a micro control unit and a wireless communication unit. Among them, the micro control unit can obtain the water meter parameter information of the mechanical water meter. Optionally, the parameter information of the mechanical water meter at least includes a unique identification code of the mechanical water meter, a timestamp when the initial water meter image is acquired, and the positioning information of the water meter. Among them, the unique identification code and positioning information of the mechanical water meter may be pre-configured in the agricultural and animal husbandry irrigation water meter monitoring device. Optionally, the main control module also includes a positioning unit, which is configured to locate the current position information of the associated mechanical water meter. Furthermore, the positioning information may also be obtained by means of the positioning unit, and the timestamp when the initial water meter image is acquired may be determined according to the time information in the micro control unit or an additional timing unit. Then the micro control unit packages the water meter parameter information and the water meter image to be detected together for processing. The wireless communication unit may be a low-power, low-cost wireless communication module, which is used to upload the packaged data packet including the water meter parameter information and the water meter image to be detected to the Internet of Things monitoring terminal.

[0050] For example, the image of the water meter to be detected transmitted by the water meter image acquisition module can be received through the UART serial port. Accordingly, the micro control unit obtains the current water meter parameter information of the mechanical water meter and packages it with the water meter to be detected into a data packet. The wireless communication module can use a GPRS or NB-IOT module to upload the data packet to the Internet of Things monitoring terminal. Combined with the water meter image acquisition module, the minimized upload of the water meter image is achieved.

[0051] The technical solution of this embodiment is to install an agricultural and animal husbandry irrigation water meter monitoring device for a mechanical water meter, collect a water meter image with a low data volume through a macro camera in a water meter image acquisition module, and compress and encode the water meter image through an image encoding unit, thereby obtaining water meter parameter information through a micro control unit of a main control module, and packaging the water meter parameter information and the water meter image, and uploading the data packet including the water meter parameter information and the water meter image to an Internet of Things monitoring terminal through a wireless communication unit. The embodiment of the present invention is based on an agricultural and animal husbandry irrigation water meter monitoring device installed for a mechanical water meter in an agricultural and animal husbandry irrigation scenario, realizes macro photography of a water meter to be monitored, and minimizes uploading of the collected water meter image, provides a basis for visual-based online monitoring of water meters, reduces the use cost of equipment in agricultural and animal husbandry irrigation scenarios, and improves the accuracy of data monitoring.

[0054] In a specific embodiment of the present invention, the fill light unit can be used to detect the lighting environment when the macro camera is shooting, so as to adjust the lighting conditions of the mechanical water meter in the absence of light or dim light, and avoid the situation where there is no light or reflection during macro shooting, which affects the shooting. Furthermore, the agricultural and animal husbandry irrigation water meter monitoring device in this embodiment is not affected by the agricultural and animal husbandry irrigation lighting environment, and supports fill light shooting in a lightless environment. Exemplarily, LED can be used for fill light adjustment.

[0055] Optionally, the main control module 122 further includes a data storage unit 1223, and the data storage unit 1223 is configured to store the image of the water meter to be detected and parameter information of the mechanical water meter.

[0056] In a specific embodiment of the present invention, the data storage unit is used to store the image of the water meter to be detected and the parameter information of the mechanical water meter, and can also store information such as cache data in the data processing process or instructions issued by the Internet of Things monitoring terminal.

[0058] In a specific embodiment of the present invention, the power management unit can control the power supply mode or working state of the power supply module according to the control of the micro control unit. The power supply module can be powered by a passive battery and based on a dual-state alternating working mode of sleep and wake-up to minimize the energy consumption of the device.

[0059] The technical solution of this embodiment, by adding a fill light unit to the water meter image acquisition module, can not only ensure the clarity under normal lighting conditions during macro shooting, but also achieve a clear effect under weak light conditions through its own light source, and can remove interference such as reflections. By adding a data storage unit to the water meter image acquisition module, a data caching function is provided. At the same time, the agricultural and animal husbandry irrigation water meter monitoring device also includes a power supply module to minimize the energy consumption of the device without affecting the normal operation of the equipment.

Thus, the Internet of Things monitoring terminal responds to the user's operation instruction and sends a control instruction to the agricultural and animal husbandry irrigation water meter monitoring device.

[0066] Correspondingly, the agricultural and animal husbandry irrigation water meter monitoring device receives the control instruction, parses the control instruction through the micro control unit, and thus controls the corresponding action object. Exemplarily, the image acquisition state or frequency of the macro camera in the water meter image acquisition device can be controlled, such as manually triggering the macro camera to acquire water meter images, thereby triggering the monitoring function; or acquiring water meter images according to the configured frequency; or acquiring water meter images when water pressure is detected, etc. The working mode of the power supply module can also be controlled to reduce invalid power supply and reduce equipment power consumption. In addition, for large-caliber mechanical water meters, such as metering devices that measure water resources flowing through water supply pipes with a diameter of DN40-DN300, water pressure control can be used to support valve state control of mechanical water meters.

[0067] The technical solution of this embodiment can realize the function of controlling the agricultural and animal husbandry irrigation water meter monitoring device and / or the mechanical water meter by receiving the control instruction issued by the Internet of Things monitoring terminal through the agricultural and animal husbandry irrigation water meter monitoring device while realizing the monitoring of the mechanical water meter.
