Description

Technical Field

[0001] This invention relates to the field of valve controller technology, and in particular to a low-power dual-channel wireless valve controller with switch feedback. Background Technology

[0002] Wireless solenoid valve controllers are widely used in agriculture, animal husbandry, and landscaping for remote control and management of irrigation systems. Since these applications typically lack power supply facilities, the controllers require power from batteries and solar panels. Therefore, the controller's power consumption is a particularly important technical indicator, and the accuracy of its control over the opening and closing of the solenoid valves reflects the controller's reliability.

[0003] Currently, there are some similar wireless valve control boxes available both domestically and internationally, but their operating time in battery-powered mode is typically only 3-15 days. This is because existing technologies have some issues with power consumption control and energy saving, leading to excessively rapid battery depletion.

[0004] First, existing technologies often use traditional communication protocols and high-power wireless modules. These modules generate high power consumption during operation, leading to increased power consumption. Furthermore, these modules typically need to communicate and receive commands constantly, further increasing power consumption.

[0005] Secondly, existing technologies do not adequately optimize battery management. For example, they lack sophisticated power consumption control and energy-saving strategies, and fail to take effective measures to extend battery life. This results in short controller operating time in battery-powered mode, and the inability to guarantee the correct opening or closing of solenoid valves. Due to their high power consumption, solar panels are made very large to ensure sufficient power, which is inconvenient for installation and implementation in actual projects, and also increases costs.

[0006] Furthermore, in the field of wireless valve controllers both domestically and internationally, when sending open or close commands to a solenoid valve, most existing products cannot accurately determine whether the solenoid valve is actually open or closed, resulting in a certain degree of misjudgment. This is because traditional wireless valve controllers mainly rely on signal transmission and reception to determine the valve status, and cannot obtain the actual status of the valve in real time, leading to a certain degree of uncertainty in determining the solenoid valve's on / off state.

[0007] In summary, existing technologies suffer from problems such as high controller power consumption, short battery life, inability to accurately determine the solenoid valve's on / off status, and difficulty in installation. Summary of the Invention

[0008] To overcome the shortcomings of the prior art, the purpose of this invention is to provide a low-power dual-channel wireless valve controller with switch feedback.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide a low-power dual-channel wireless valve controller with switch feedback. This invention solves the problems of high power consumption, short battery life, inability to accurately determine the solenoid valve switching status, and difficulty in installation of existing controllers.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 As shown, the present invention provides a low-power dual-channel wireless valve controller with switch feedback, comprising:

[0033] The system includes a microcontroller module, a lithium battery, a boost module, and a first solenoid valve switch control module, a second solenoid valve switch control module, a wireless communication module, and a solenoid valve power supply management module connected to the microcontroller module. The lithium battery and the boost module are both connected to the solenoid valve power supply management module.

[0034] The microcontroller module is used to implement intelligent sleep mode and task scheduling of the first solenoid valve switch control module, the second solenoid valve switch control module, the wireless communication module, and the solenoid valve power supply management module according to user instructions and through microcontroller programs. The lithium battery is used to power the microcontroller module, the boost module, the first solenoid valve switch control module, the second solenoid valve switch control module, the wireless communication module, and the solenoid valve power supply management module. The solenoid valve power supply management module is used to control the first solenoid valve switch control module and the second solenoid valve switch control module to enter the working state through the boost module. The wireless communication module is used to realize the transmission of user instructions and microcontroller data. The first solenoid valve switch control module is used to control the opening and closing of the first valve, and the second solenoid valve switch control module is used to control the opening and closing of the second valve.

[0035] Specifically, the most advanced low-power LoRa wireless communication module, based on the SX1262 chip, is selected both domestically and internationally. This reduces power consumption during communication, lowering the receiving current from 12mA in similar products to 5mA. It enables sending and receiving commands to cloud servers or mobile phones via 4G communication.

[0036] Furthermore, it also includes:

[0037] Interconnected solar panels and solar charging management module;

[0038] The solar panel is used to charge the lithium battery through the solar charging management module.

[0039] like Figure 2-4 As shown, the ultra-low power MSP430G2553 MCU (microcontroller) is selected. This MCU is manufactured by TI (Texas Instruments) in the United States. Based on its electrical and pin structure, a microcontroller control program completely independently developed by our company is injected. The program developed by our company controls the various input / output (IO) pins of the MCU. The MCU's input / output pins are connected to the wireless transmission module, solenoid valve power supply management module, solenoid valve control module A (first solenoid valve control module), and solenoid valve control module B (second solenoid valve control module) on the controller. When the user does not send a solenoid valve switching command, the microcontroller (microcontroller module) controls the controller to put all modules except the MCU, LDO 3.3V step-down power supply module, and solar charging module into a sleep standby state through program control, realizing intelligent sleep and greatly reducing the overall power consumption of the controller. When a user sends a solenoid valve switch command, the wireless transmission module transmits the received command to the MCU (microcontroller). The MCU, through our program, activates the solenoid valve power management module and the 12V boost module. Simultaneously, based on the received command, the MCU, through our program, controls whether solenoid valve control module A or solenoid valve control module B is active, achieving task scheduling and controlling the switching of solenoid valves A or B. Once the solenoid valve switch action is completed, the controller enters a sleep state, awaiting the next switch command. During the sleep state, the average operating current of the entire controller is below 1.1mA. Each control box is equipped with a small 4400mAh lithium battery, theoretically allowing for continuous operation for 4000 hours (166 days) without solar charging. In actual use, without the addition of a micro solar panel, the solenoid valve can operate stably for over 120 days. Compared to similar products at home and abroad, which can only guarantee solenoid valve operation for 3-15 days without solar panels, our power consumption is reduced by 8-40 times.

[0040] Furthermore, the solar panel area is greater than 30cm². The controller of this invention can operate stably year-round simply by attaching a 30cm² solar panel to the controller box, with low requirements for sunlight. This is of great significance for planting areas without power supply, especially during the rainy season and prolonged cloudy days in southern my country, ensuring the long-term stable operation of the solenoid valve! At the same time, compared with similar products at home and abroad, the significantly reduced size of the solar panel makes our controller installation very convenient, greatly reducing construction costs and fixing materials.

[0041] Due to the reduction in the overall power of the controller, a miniature solar panel, no smaller than 30cm², can provide a continuous and reliable power supply to the controller, ensuring stable operation of the solenoid valve throughout the year. Because the size of the solar panel is significantly reduced, the controller and solar panel can be integrated, making installation of the controller very convenient and greatly reducing construction costs and fixing materials.

[0042] Furthermore, the microcontroller module includes:

[0043] Two switch feedback pins are connected to the water flow toggle switch of the first valve and the water flow toggle switch of the second valve, respectively, to obtain the switch status information of the first valve and the switch status information of the second valve. The microcontroller module determines the switch status of the first valve and obtains the switch status of the second valve based on the switch status information of the first valve and the switch status information of the second valve.

[0044] Specifically, a water flow toggle switch is installed on the side of the solenoid valve's outlet. When the solenoid valve is open, the water flow impacts the toggle switch, causing it to close. Conversely, when the solenoid valve is closed, there is no water flow impacting the toggle switch. The two water flow toggle switches of solenoid valve A (the first valve) and solenoid valve B (the second valve) are connected to two input pins of the MCU. The MCU (microcontroller) monitors the level of the two input pins through our developed program, thus determining the actual on / off state of solenoid valves A and B. It then sends the on / off monitoring status to the server and the user's mobile phone, achieving precise on / off feedback.

[0045] This invention's controller achieves a 100% success rate in controlling solenoid valves, significantly improving the reliability of wireless valve controllers. When the solenoid valve itself malfunctions or is lost, this technology enables a solenoid valve fault alarm. This has significant practical implications in real-world applications!

[0046] Furthermore, in intelligent sleep mode, the current of the working circuit of the dual-channel wireless valve controller is 1.1mA.

[0047] The beneficial effects of this invention are as follows:

[0048] Extremely low power consumption: By adopting advanced low-power communication protocols and wireless modules, as well as intelligent power management technology, this invention reduces the power consumption of the controller, which greatly extends the battery life and enables stable operation for more than 120 days.

[0049] like Figure 5As shown, it is easy to install: due to the reduced power consumption of the controller, it only needs to be attached to a 30cm2 micro solar panel to work stably for a long time, and the requirements for sunlight are low. This greatly facilitates on-site installation and implementation, and reduces the overall cost and expense of project implementation.

[0050] Switch feedback function: Introducing innovative switch feedback technology, it can monitor the actual switching status of the solenoid valve in real time, thereby accurately determining whether the solenoid valve is closed or open, improving the reliability and stability of the controller.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
