Moreover, a manager is required to be responsible for the irrigation activities of 5-10 greenhouses; if there is a node leakage problem in the irrigation network during the irrigation process, the waste of water resources is secondary, and the important thing is that the leaked irrigation network will affect the crops. have a devastating effect
Because there are generally no drainage channels in greenhouses

Embodiment 1

[0068] Such as Figure 4 As shown in the case of using the greenhouse form, due to the adoption of the greenhouse form, even if the management personnel manage the nearby greenhouses, they cannot find the irrigation network with node leakage in time. It needs to be discovered when the water overflows the greenhouse, but it is too late at this time, and the entire greenhouse has been flooded. Therefore, this system needs to be installed to prevent such things from happening. The appearance of such things is generally caused by other reasons such as the aging of the sealing ring, but because the irrigation net is attached to the ground, it will be subject to various corrosions, so it is not uncommon at this time. Moreover, each experiment takes a long time to complete. At the same time, whether it is for experiments or planting crops, especially for experiments, the seeds used are all screened. If some accidents cause the experiments to be unable to proceed normally, A lot of t...

Embodiment 2

[0074] In the non-greenhouse mode of farmland irrigation, it is generally possible to judge with the naked eye whether node leakage occurs, but it is not easy to judge when the crops grow. Therefore, the system still needs to be installed. If only the method of video surveillance is installed, managers need to watch the video from time to time, or need to inspect occasionally. This approach greatly increases the labor intensity of managers.

[0075] Through this system, the network mode of 4G mobile phone card can be used, which can allow managers to manage more and larger farmland. Due to the large area of ​​farmland, leakage can occur, as long as the time is not long, it will have little impact. Therefore, in the farmland mode, a manager basically manages the irrigation and node leakage of more than 20 farmlands a day through this system. And do not need other activities such as patrols, the above activities can be completed indoors, greatly reducing labor intensity and ma...

Abstract

The invention discloses a multifunctional leakage node determination system for farmland irrigation network. The multifunctional leakage node determination system comprises a hardware part and a software part, wherein the hardware part comprises an irrigation net, wherein a solenoid valve is mounted on a main water inlet pipe of the irrigation net; a wireless communication module is connected to the solenoid valve; a pressure sensor is mounted on the main water inlet pipe; an acquisition module is connected to the pressure sensor; the acquisition module and the wireless communication module are connected to a CPU module; a storage module is also connected to the CPU module; and a video monitoring module is also connected to the CPU module; and the software part comprises a mobile phone terminal, and software on the mobile phone terminal comprises a flow curve module, an alarm module, a control module, a greenhouse addition module and a video monitoring module. The multifunctional leakage node determination system disclosed by the invention has the advantages that a correction ratio is high, leakage errors can be effectively determined, and corresponding actions can be executed, so that water conservation is realized and convenience is provided for users. The system disclosed by the invention can work under a variety of environments, that is, the system can stably work in large fields, greenhouses and areas being shortage of power supply.

Description

technical field [0001] The invention relates to the agricultural field, in particular to a multifunctional farmland irrigation network leakage node judging system. Background technique [0002] At present, in farmland irrigation, especially in greenhouses, most of them are irrigated in the form of irrigation nets. Moreover, a manager is required to be responsible for the irrigation activities of 5-10 greenhouses; if there is a node leakage problem in the irrigation network during the irrigation process, the waste of water resources is secondary, and the important thing is that the leaked irrigation network will affect the crops. have a devastating effect. Because there are generally no drainage channels in greenhouses. The occurrence of this situation is mainly due to the fact that the irrigation network has been used for a long time and the sealing rubber ring of a certain node is aging. In the actual observation and practice process, when the irrigation system is runnin...
