[0002] With the rapid development of industrial automation and Internet of Things technology in recent years, the application of remote monitoring and intelligent control systems has become increasingly widespread. Especially in fluid control systems, valve controllers, as key components, have significantly enhanced their intelligence and remote control trends. The integration of wireless communication technology, especially the rise of low-power wide area network (LPWAN) technology, has brought revolutionary changes to valve controllers. Among them, long-range radio (LORA) technology, with its advantages of long-distance transmission, low power consumption, and high penetration, has shown great potential in many fields such as smart agriculture, urban water supply systems, and industrial process control. The LORA valve controller can achieve remote monitoring and precise control, greatly improving the efficiency and flexibility of the system and reducing maintenance costs.

[0003] However, there are still some shortcomings in the wireless LoRa valve controllers currently on the market, which limit the full application of their effectiveness. First, energy supply has become a major bottleneck. Most products rely on grid power or traditional batteries, which not only increases the complexity of installation and maintenance, but also limits their application in remote areas or areas where it is inconvenient to lay cables. Secondly, some controller designs use solenoid valves for control, but they only have two states, open and closed, making it difficult for users to flexibly configure according to actual needs. Therefore, we propose a wireless LoRa valve controller. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, a wireless LORA valve controller provided by an embodiment of the utility model includes a wireless gateway 3 and a column 1, a solar panel 10 is fixedly connected to the front side of the wireless gateway 3, an antenna 9 is fixedly connected to the upper part of the wireless gateway 3, a support frame 2 is fixedly connected to the upper part of the column 1, the support frame 2 is connected to the wireless gateway 3 by bolts, a LORA data transmission module is arranged inside the wireless gateway 3, the LORA data transmission module is respectively connected to the first valve assembly 5 and the second valve assembly 4 by two groups of signal lines, a plug rod 6 is fixedly connected to the lower part of the column 1, and the structures of the first valve assembly 5 and the second valve assembly 4 are the same.

[0025] Fixing the solar panel 10 on the front side of the wireless gateway 3 is a design choice that is both energy-saving and environmentally friendly. Considering that valve controllers are often deployed outdoors or in remote locations, traditional power supply access is inconvenient and maintenance costs are high. The solar power supply solution effectively overcomes these problems. By directly converting solar energy into electrical energy, the continuous operation of the wireless gateway 3 and the LORA data transmission module is ensured, reducing dependence on external power supplies, and improving the system's self-sufficiency and long-term operational stability.

[0026] The wireless gateway 3 is embedded with a LORA data transmission module. By utilizing the low power consumption and long-distance transmission characteristics of LORA technology, the controller can achieve remote and reliable signal transmission in complex industrial environments or vast farm irrigation systems. Compared with traditional wireless communication methods, LORA technology can better penetrate obstacles, reduce signal attenuation, ensure the accurate transmission of control instructions, and improve the immediacy and accuracy of valve control, which is crucial for remote automation management.

[0027] The stable connection between the column 1 and the support frame 2 is fixed by bolts, which not only provides physical support for the wireless gateway 3, but also ensures the stability of the entire system under adverse outdoor weather conditions. Such a structural design is conducive to rapid installation and maintenance, and also enhances the system's ability to resist factors such as wind loads and vibrations, prolongs its service life, and is the basis for achieving long-term unattended operation.

[0028] The first valve assembly 5 includes a base 51 , and two vertical plates 54 are fixedly connected to the upper portion of the base 51 . The left vertical plate 54 is connected to the first clamping jaw 53 via a rotating shaft, and the right vertical plate 54 is connected to the second clamping jaw 56 via a rotating shaft.

[0029] A stable and flexible mechanical structure is formed by two vertical plates 54 on the base 51 and the first clamping jaw 53 and the second clamping jaw 56 connected to each other. This design can accurately surround and fix the water valve, ensuring stable control of the valve under various operating conditions, and solves the adaptability problem of the traditional single clamping mechanism on complex or irregular water valve shapes.

[0030] A battery box 52 is fixedly connected to the upper left side of the base 51 , and a bracket 55 is fixedly connected to the upper portion of the vertical plate 54 .

[0031] The battery box 52 on the upper left side of the base 51 provides auxiliary power for the entire valve controller, ensuring that basic functions can be maintained in the event of insufficient solar power supply or power outage, thereby enhancing the reliability and continuous working ability of the system and avoiding control interruptions caused by energy problems.

[0032] A water valve pipe portion 11 is provided on the upper portion of the bracket 55 , a water valve handle portion 12 is rotatably connected to the lower portion of the water valve pipe portion 11 , and a water valve joint portion 13 is connected to one end of the water valve pipe portion 11 .

[0033] The arrangement of the bracket 55 provides a stable support for the water valve pipe portion 11 , thereby improving the stability of the entire system.

[0034] The first clamping jaw 53 and the second clamping jaw 56 are connected by a long bolt 57 , and a hand-tightened nut is connected to the long bolt 57 .

[0035] The first clamping jaw 53 and the second clamping jaw 56 are connected by a long bolt 57 and provided with a hand-tightened nut thereon, so as to facilitate quick adjustment of the clamping jaw spacing on site to adapt to valves of different sizes, thus reflecting the humanization and practicality of the design, simplifying the installation and debugging process and reducing the difficulty of maintenance.

[0036] The first clamping jaw 53 and the second clamping jaw 56 are respectively provided with a toothed portion 58 on their inner sides.

[0037] The design of the latching teeth 58 enhances the friction and stability during clamping, and can maintain a firm hold on the valve even in an environment of external vibration or pressure changes, thereby improving the stability of control and avoiding operational errors caused by accidental loosening.

[0038] A stepper motor 59 is disposed inside the base 51 . A handle clamp 7 is fixedly connected to the upper end of the output shaft of the stepper motor 59 . A stepper motor driver 8 is disposed inside the base 51 .

[0039] The stepper motor 59 and the stepper motor driver 8 integrated in the base 51 directly drive the water valve handle 12 through the handle fixture 7, thereby realizing accurate positioning and automatic control of the valve. Compared with traditional motors or manual control, the use of the stepper motor 59 can achieve precise control of small angles, meet the demand for precise regulation of water flow, and improve the level of automation and control accuracy.

[0040] When in use, the solar panel 10 captures and converts sunlight into electrical energy, continuously supplies power to the wireless gateway 3 and the internal LORA data transmission module, ensuring the system's uninterrupted operation around the clock. This design reduces dependence on external power sources and is particularly suitable for remote areas or areas where it is inconvenient to lay power lines.

[0041] The LORA data transmission module receives control instructions from the remote monitoring center. By utilizing the low power consumption and long-distance transmission characteristics of LORA technology, it can ensure stable signal transmission even in complex environments, thus improving the real-time and accuracy of control instructions.

[0042] After receiving the control signal, the stepper motor 59 in the first valve assembly 5 drives the handle fixture 7 according to the command, and realizes the precise positioning and control of the water valve handle 12 through precise stepping control. This process ensures that valves of various sizes are firmly clamped without external interference through the double clamping claws and the toothed portion 58 connected by the long bolt 57, thereby improving the stability and accuracy of the valve switch.

[0043] As the stepper motor 59 rotates, the handle fixture 7 and the water valve handle 12 rotate accordingly, and the water flow is turned on or off by the water valve handle 12, thereby achieving precise control of the flow of liquid. In this process, the bracket 55 provides necessary support for the water valve pipe 11, and the battery in the battery box 52 provides additional energy guarantee for the stepper motor 59 and other electronic components, ensuring that the system can work normally even on rainy days or at night.

[0044] The model of the LORA data transmission module is F8L10C, the model of the wireless gateway 3 is F8L10GW-L, and the model of the stepper motor driver 8 is AHD825X.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
