DETAILED DESCRIPTION

[0064] The technical solutions in the embodiments of the application will be described below with reference to the drawings in the embodiments of the application.

[0065] Please refer to Figure 1 , Figure 1 The functional module diagram of the control device provided in the embodiment of the application is shown in the figure. The control device is installed on the water outlet stake valve for irrigation, and is used to control the on-off state of the water outlet stake valve. The control device comprises an actuator, a wireless communication module, a master control module and an execution control circuit. The actuator is connected with the on-off control component of the water outlet stake valve, the wireless communication module, the execution control circuit and the master control module are connected, the execution control circuit is connected with the actuator, and the execution control circuit is used to drive the actuator.

[0066] In the embodiment of the application, the actuator is directly connected with the on-off control component of the water outlet stake valve, and is responsible for executing the opening and closing actions of the valve. The wireless communication module is used to receive the control instructions from the client or the server. The master control module serves as the core of the control device, is responsible for processing the control instructions received by the wireless communication module, and generates corresponding control signals according to the instruction content. The execution control circuit connects the master control module and the actuator, and is responsible for converting the control signals output by the master control module into driving signals that can be understood by the actuator. Through the control device of the embodiment, the user can realize the on-off control of the water outlet stake valve through remote control of the device without going to the field, which greatly saves time and effort, improves the irrigation efficiency, and can also realize accurate control of the irrigation time and water quantity, reducing the waste of water resources.

[0067] The main control module can be an MCU (microcontroller), DSP (digital signal processor), MPU (microprocessor), FPGA (field programmable gate array), ARM architecture processor, etc.

[0068] A client can refer to an application used by a user, which runs on a client device. A client device can be a mobile phone, laptop, tablet, PC, dedicated handheld device, etc. Alternatively, a client can refer to the client device used by the user, including both hardware and software.

[0069] Users can send control commands to the control device through the client. Of course, the control device can also feed back some data, such as the device's status information (e.g., power consumption, network connection status, sensor data, water pressure data, etc.), to the client so that the user can know and make corresponding decisions, such as whether irrigation should be carried out, or whether the control device needs to be replaced or repaired.

[0070] A server can include both hardware and software, or it can consist only of server-side programs. For example, an irrigation system manufacturer could purchase a computer and install server-side programs on it to serve as the server in the irrigation system, or it could simply develop the server-side programs and deploy them on a rented cloud server.

[0071] Communication between the client and the server can occur in different ways: For example, if the client device is a mobile communication terminal (such as a mobile phone), the client can establish a communication connection with the server through a mobile communication network. Alternatively, if the client device is not a mobile communication terminal (such as a PC), the user can use a computer network to manage and control the device by accessing a specific URL provided by the server through a browser. In this case, the client can be considered as a browser or a specific webpage opened within a browser.

[0072] In some alternative implementations, the main control module employs a low-power MCU that enters sleep mode when not in operation and can be woken up by the wireless communication module. Furthermore, the wireless communication module also has a wake-up function; it operates in a low-power state when data reception is not required, and can be quickly woken up when data reception is needed.

[0073] In some alternative implementations, the wireless communication module includes a first wireless communication module, such as... Figure 2 As shown; the first wireless communication module is used to form a local area network with other control devices.

[0074] In the embodiments of the present application, the first wireless communication module allows each control device to communicate with each other in the local area network, so that multiple water outlet pile valves in the farmland can be uniformly managed and controlled through the local area network. Specifically, the first wireless communication module can be constructed based on wireless communication standards such as LoRa, Starlink, etc. The specific selection of which standard depends on the actual application scenario and requirements, such as communication distance, power consumption, cost, etc. The local area network can adopt various topological structures such as star, tree, mesh, etc.

[0076] The mobile communication module includes multiple 2 / 3 / 4 / 5G mobile communication modules, each of which carries an operator SIM card, forming a multi-network multi-standby multi-communication system, such as a dual-network dual-standby dual-communication system (2-way mobile communication module with 2 operators), or a triple-network triple-standby triple-communication system (3-way mobile communication module with 3 operators). Multiple operator networks are simultaneously connected to the server, and the control device automatically selects the best operator network for communication with the server to ensure stable connection of the mobile network signal.

[0077] In the embodiments of the present application, the user sends control instructions to the server using a client (such as a mobile phone APP, computer software, etc.), and the server transmits these instructions to the control device through the mobile communication network. At the same time, the control device can also upload its state data, monitoring information, etc. to the server through the mobile communication module, improving the remote control capability of the control device. The above workflow specifically includes:

[0078] The user inputs control instructions or initiates query requests through the client.

[0079] The server receives the instructions or requests and performs necessary processing (such as verifying the user's identity, parsing the instructions, etc.).

[0080] The server sends the processed instructions to the corresponding control device through the mobile communication network.

[0081] The control device receives the instructions through the mobile communication module and performs corresponding operations (such as opening / closing the valve).

[0082] At the same time, the control device can periodically or on demand upload state data (such as valve status, battery level, etc.) to the server.

[0083] The server presents the received state data to the client for viewing and analysis by a user.

[0084] The mobile communication module can communicate based on 2G / 3G / 4G / 5G mobile communication networks, and the specific network to be selected depends on specific communication requirements, coverage, cost, and other factors.

[0085] In some optional embodiments, the wireless communication module further includes a second wireless communication module, such as Figure 3 as shown in the figure.

[0086] The second wireless communication module is used for close-range wireless communication with the client.

[0087] In the embodiments of the present application, the second wireless communication module allows the control device to perform close-range wireless communication with the client (such as a smart phone, a tablet computer, etc.), and this communication mode does not depend on the mobile communication network. When the mobile communication network signal is weak or there is no signal, the control device can also be controlled through the client. Considering that existing smart phones and tablet computers and other clients have widely integrated wireless communication modules such as Bluetooth, Wi-Fi, and NFC, the second wireless communication module can adopt Bluetooth, Wi-Fi, NFC (Near Field Communication), etc.

[0088] In some optional embodiments, the second wireless communication module includes a WiFi module and / or a Bluetooth module; and the first wireless communication module includes a Lora module.

[0089] In the embodiments of the present application, the Lora technology has good penetration and supports a relatively long communication distance, and does not need to deploy a base station, so it is very suitable for field application and is also suitable for use in some remote areas. WiFi and Bluetooth are standard configurations of many devices (such as mobile phones, notebook computers, and tablet computers), so the second wireless communication module selects a WiFi module or a Bluetooth module to facilitate communication with the device where the client is located.

[0090] The control device of one or more embodiments of the present application is installed on a water outlet pile valve, which can be a ball valve, a gate valve, a stop valve, a butterfly valve, etc. The following embodiments take the water outlet pile valve as a ball valve as an example for illustration.

The control device 1 can control the opening and closing states of the water outlets of the ball valve 6. Taking the three-way valve as an example, the control device 1 can control the two water outlets to be opened or closed at the same time, or can independently control the opening or closing of each water outlet, or can control the opening degree of each water outlet, such as 5 degrees, 10 degrees, etc. Of course, the specific control mode depends on the structure of the ball valve 6 itself, such as whether the ball valve 6 supports independent opening or closing of each water outlet, and also depends on the connection mode of the control device 1 and the ball valve 6. In the embodiment, the wireless communication module, the execution control circuit and other modules are arranged on the main control board 11.

[0107] In some optional embodiments, the interaction module further includes a ball valve 6 rotation indication structure, which is fixedly connected with the actuator 12, and is used to rotate with the actuator 12 when the actuator controls the ball valve 6 to open or close, thereby indicating the rotation direction and angle of the ball valve 6.

[0108] In the embodiment of the application, the water outlet valve adopts a ball valve 6, and the ball valve 6 rotation indication structure is fixedly connected with the actuator 12. When the actuator 12 rotates to open or close the ball valve 6, the ball valve 6 rotation indication structure will rotate accordingly, thereby directly indicating the rotation direction and angle of the ball valve 6. The ball valve 6 rotation indication structure is designed in the shape of an arrow or other easily recognizable graphics, and its rotation range should match the rotation range of the ball valve 6.

[0109] In other embodiments, the water outlet valve can also adopt a gate valve, a stop valve, a butterfly valve, etc. Different types of valves have different opening and closing modes, and different indication structures can be designed according to the specific opening and closing mode and fixedly connected with the actuator 12. The actuators 12 corresponding to different types of valves can be the same or different.

[0110] Please refer to Figure 6 , Figure 6 The structure of the actuator 12 provided in the embodiment of the application is shown in the figure. The actuator 12 of the embodiment includes a motor 121 and a gear set 122. One end of the gear set 122 is connected with the rotating shaft of the motor 121, and the other end of the gear set 122 is connected with the valve rod of the ball valve 6. The gear set 122 connects the rotating shaft of the motor 121 and the valve rod of the ball valve 6, and realizes the function of speed reduction. The gear set 122 can convert the high-speed rotation of the motor 121 into the low-speed and high-torque rotation movement required by the valve rod.

[0111] The gear set 122 achieves deceleration through multi-stage gear transmission. The basic principle is to use a small gear to drive a large gear, and use the gear ratio to achieve deceleration. When the motor 121 drives the small gear to rotate, the large gear will rotate at a lower speed due to the larger number of teeth, thereby achieving the effect of deceleration. This deceleration effect enables the high-speed rotation of the motor 121 to adapt to the low-speed, high-torque requirements of the valve stem. Accompanying the deceleration effect is the increase in torque. When the speed of the gear set 122 is reduced, the torque output by the gear set 122 will increase accordingly. This is crucial for controlling the opening and closing of the ball valve 6, as the ball valve 6 usually requires a large torque to be reliably closed or opened.

[0112] When the motor 121 receives the drive signal of the execution control circuit, the rotational power generated by the motor 121 is transmitted to the gear set 122 through the shaft. The gear set 122 decelerates and increases torque according to the preset gear ratio, and then transmits the processed power to the valve stem, thereby controlling the opening and closing of the ball valve 6.

[0113] In some optional embodiments, the control device 1 further comprises a battery 16, a shell, and an antenna 13; the antenna 13 is connected to the wireless communication module; the shell comprises an antenna 13 accommodating cavity, a functional module accommodating cavity, and a battery compartment; the antenna 13 is placed in the antenna 13 accommodating cavity; the main control board 11 is placed in the functional module accommodating cavity; and the battery is placed in the battery compartment. The shell of the embodiment specifically comprises an upper shell 14 and a lower shell 15, the antenna 13 accommodating cavity is arranged on the upper shell 14, the functional module accommodating cavity and the battery compartment are arranged on the lower shell 15, and the battery compartment is further provided with an opening, and the battery compartment cover 17 is arranged at the opening of the battery compartment.

[0114] In the embodiment, the antenna 13 is built-in in the control device 1, which can avoid the installation and maintenance troubles of the external antenna 13, and improve the overall aesthetics and portability of the device. The built-in battery makes the control device 1 more independent and portable, and can work for a long time without relying on external power supply. Moreover, the battery compartment is provided with an opening and a battery compartment cover 17, so that the user can conveniently replace or charge the battery, thereby ensuring the continuous operation of the device.

[0115] Please refer to Figure 7 , Figure 7 The signal transmission schematic diagram between the master station device 2, the slave station device 3, the server 4, and the client 5 provided in the embodiment is shown. In the embodiment, among the plurality of control devices 1 constituting the local area network, one control device 1 has a mobile communication module, and this control device 1 serves as the master station device 2, and the other control devices 1 serve as the slave station devices 3. The master station device 2 is used to communicate with the server 4 through the mobile communication module, the client 5 is used to control the master station device 2 through the server 4 based on the mobile communication network, and the slave station devices 3 are controlled through the server 4 and the master station device 2.

[0116] In this embodiment, the master device 2 is equipped with a mobile communication module, which adopts 4G communication and is responsible for wireless communication with the server 4. The master device 2, as the center node in the local area network, is also the gateway of the local area network, and receives control instructions from the client 5. If the control instruction is for the master device 2 itself, the master device 2 receives the control instruction by itself; if the control instruction is for the slave device 3, the master device 2 forwards the control instruction to the slave device 3. The communication between the master device 2 and the slave device 3 adopts Lora communication. The master device 2 collects the state data of the slave device 3 and uploads the state data to the server 4. The Lora module of the master device and the slave device corresponds to the first wireless communication module in the above embodiment.

[0117] The local area network can have various topological structures: for example, the local area network adopts a star structure, the master device is the center node of the star structure, and each slave device is only in communication connection with the master device; for another example, the local area network adopts a tree structure, the master device is the root node of the tree structure, and the slave devices are leaf nodes or internal nodes of the tree structure, and each control device is only in communication connection with the nodes connected in the tree structure, and the like.

[0118] The slave device 3 does not have a mobile communication module, but communicates with the master device 2 through the local area network. The slave device 3 executes the control instruction forwarded by the master device 2, such as opening / closing a valve, adjusting the irrigation amount, and the like. The slave device 3 sends its own state data to the master device 2.

[0119] The server 4 receives control instructions or query requests from the client 5. The server 4 forwards the instructions or requests to the master device 2 and receives the state data uploaded by the master device 2. The server 4 stores and processes the data and provides functions such as historical records and analysis reports for users.

[0120] The user sends control instructions or query requests to the server 4 through the client 5. The client 5 also receives the state data or analysis report returned by the server 4, which is used for monitoring and managing the irrigation system.

[0121] In this embodiment, the master device 2 also has a Bluetooth module, and the Bluetooth module of the master device corresponds to the second wireless communication module in the above embodiment. In the case that the 4G network signal is weak or the user is close to the master device 2, the master device 2 and the client 5 of the user can communicate through Bluetooth, so that the application range of the system is wider, and it is also applicable to some remote areas without mobile communication network.

[0122] In some optional embodiments, in one implementation, the slave device 3 is also provided with a Bluetooth module, and the slave device 3 can also communicate with the client 5 directly through the Bluetooth module, and the client 5 can also control the slave device 3 provided with the Bluetooth module directly based on the short-range wireless communication, and control the master device 2 and other slave devices 3 through the slave device 3.

[0123] In the above-described embodiments, only the master device 2 can directly communicate with the client 5 based on the short-range wireless communication, because the master device 2 is provided with the Bluetooth module. However, if a slave device 3 is far away from the master device 2 (for example, the local area network adopts a tree structure), and the client 5 is located near the slave device 3, the client 5 can not be connected to the master device 2 based on the short-range wireless communication, and thus the slave device 3 can not be controlled. The above-described implementation can effectively solve this problem: by adding the Bluetooth module in the slave device 3, even if the client 5 is far away from the master device 2, the client 5 can still communicate with the slave device 3 near the client 5, so as to control the slave device 3, and even control more devices through the slave device 3, and thus it is beneficial to support the irrigation system to be deployed in a larger geographical range.

[0124] The master device 2 and the slave device 3 in the embodiments are both installed on the water outlet pile valve, and the installation manners are similar, and the structures are similar, so that unified design and manufacturing are facilitated, and production and manufacturing costs are saved.

[0125] In the embodiments provided in the present application, it should be understood that the disclosed devices and methods can be implemented in other manners. The above-described device embodiments are only schematic. For example, the division of the units is only a logical function division. There can be another division manner for the actual implementation, for example, multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. In addition, the displayed or discussed mutual couplings or direct couplings or communication connections between the units can be indirect couplings or communication connections through some interfaces, devices or units, and can be electrical, mechanical or in other forms.

[0126] In addition, the units described as separate components can or can not be physically separate, and the components displayed as units can or can not be physical units. That is, they can be located in one place, or can be distributed on a plurality of network units. Some or all of the units can be selected according to actual needs to achieve the purposes of the embodiments.
