[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0036] The embodiment of the present invention discloses an irrigation area metering device integrating measurement, control and management, including a first irrigation channel 1, a second irrigation channel 2 located downstream of the first irrigation channel 1, and the first irrigation channel 1 is connected to the second irrigation channel through a connecting pipe 3 Channel 2 is connected;
[0037] A pipe flow meter 4 and a gate 5 are installed inside the connecting pipe 3, and the pipe flow meter 4 is arranged behind the gate 5;
[0038] The soil irrigated by the second irrigation channel 2 is provided with a soil moisture sensor 6 for sensing the water demand, and the gate 5 and the soil moisture sensor 6 are electrically connected through a remote control device.
[0039] Preferably, in the above-mentioned irrigation area metering equipment with integrated measurement, control and management, the gate 5 is arranged at the end of the connecting pipe 3 at the intersection of the connecting pipe 3 and the second irrigation channel 2. When water injection is required, the gate 5 is lowered. When you put it away.
[0040] Preferably, in the above-mentioned irrigation area metering equipment integrated with measurement, control and management, the gate 5 is an electric gate, which is controlled by a remote control device.
[0041] Preferably, in the above-mentioned irrigation area metering device with integrated measurement and control pipe, the connecting pipe 3 is arched.
[0042] Preferably, in the above-mentioned irrigation area metering equipment with integrated measurement, control and management, a fine mesh 7 is provided at the intersection of the first irrigation channel 1 and the connecting pipe 3.
[0043] The invention also discloses a metering method for the irrigation area metering equipment using the above-mentioned integrated measurement, control and management, including the following steps:
[0044] (1) When the water volume of the first irrigation channel reaches saturation, the water flows into the connecting pipe after passing through the fine mesh;
[0045] (2) The water flow continues to flow forward into the second irrigation channel, and the pipe flowmeter measures the water volume;
[0046] (3) After the water flows out of the second irrigation channel, it continues to flow into the soil. The soil moisture sensor detects soil moisture in real time, transmits the detection data to a remote control device, and the remote control device controls the gate according to the detection data. To control the status.
[0047] Preferably, in the above-mentioned irrigation area measurement method with integrated measurement, control and management, in step (3), when the soil moisture sensor detects that the soil moisture is higher than a set value, the remote control device controls the The gate blocks the water flow; when the soil moisture sensor detects that the soil moisture is lower than the set value, the gate is controlled to be retracted on the top of the connecting pipe.
[0048] The above-mentioned irrigation area metering equipment with integrated measurement, control and management can adjust the gate control equipment through the software platform to control the water volume remotely, and accurately measure the water volume in real time through the pipe flowmeter, and transmit the data back to the system platform in real time, providing a data basis for decision-making It provides data support for the calculation and collection of water charges, achieving accurate measurement and accurate calculation and collection, and provides basic hardware equipment for the national water-saving policy.
[0049] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other. Regarding the solution disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant part can refer to the description of the method part.
[0050] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown in this document, but should conform to the widest scope consistent with the principles and novel features disclosed in this document.
