[0018] This utility model provides a garden watering control system based on low-power remote control technology. The overall concept of the technical solution is as follows:

[0019] When it's time to water the plants in the garden, people use a watering signal transmitter inside the house. By operating the first button panel, they first select the first identifier code pre-stored in the first MCU, and then send a watering start signal. The watering signal is broadcast outward via the FSK modulation transmission circuit and the first antenna. Multiple watering signal receivers located in the garden receive the watering signal via the second antenna. The first identifier code is extracted from the watering signal by the FSK demodulation receiving circuit. The second MCU then judges whether the second identifier code it stores matches the first identifier code. Only when the second identifier code matches the first identifier code will the watering signal receiver open the solenoid valve according to the watering signal, and the water from the watering pipe will flow to the sprinkler head. When the second identifier code does not match the first identifier code, the watering signal receiver will not perform the watering operation.

[0020] The watering signal transmitter can store multiple different first identifier codes. People can operate the first button panel to select another first identifier code and send a watering signal. Then another matching watering signal receiver will perform the watering work.

[0021] People can use watering signal transmitters to remotely receive watering signals and set operations such as starting watering, continuous watering time, and stopping watering, without having to walk back and forth between the house and the garden.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] See Figure 1 and Figure 2 The preferred embodiment of this utility model.

[0024] A garden watering control system based on low-power remote control technology includes:

[0025] Watering signal transmitter 1 and watering signal receiver 2;

[0026] The watering signal transmitter 1 includes a first MCU 11, a first button panel 12, an FSK modulation transmission circuit 13, and a first antenna 14. The first MCU 11 is electrically connected to the first button panel 12 and the input terminal of the FSK modulation transmission circuit 13, and the output terminal of the modulation transmission circuit is electrically connected to the first antenna 14.

[0027] The watering signal receiver 2 includes a second MCU 21, a second button panel 22, an FSK demodulation receiving circuit 23, a second antenna 24, a solenoid valve driving circuit 25, and a solenoid valve 26. The second MCU 21 is connected to the second button panel 22, the output terminal of the FSK demodulation receiving circuit 23, and the input terminal of the solenoid valve driving circuit 25. The input terminal of the demodulation receiving circuit is electrically connected to the second antenna 24. The output terminal of the solenoid valve driving circuit 25 is electrically connected to the solenoid valve 26. The solenoid valve 26 is installed in the watering pipe 3.

[0028] The first MCU11 of the watering signal transmitter 1 stores a first identification code, and the second MCU21 of the watering signal receiver 2 stores a second identification code. The first antenna 14 of the watering signal transmitter 1 is communicatively connected to the second antennas 24 of the multiple watering signal receivers 2. When the first identification code matches the second identification code, the watering signal transmitter 1 controls the watering signal receiver 2.

[0029] The beneficial effects or advantages of this utility model are as follows: This utility model adopts low-power FSK radio frequency modulation and demodulation technology. People can use a watering signal transmitter 1 in the house to remotely control multiple watering signal receivers 2 located in the garden. There is no need to walk back and forth between the house and the garden. According to the actual watering needs of the garden, watering can be selectively controlled by using preset identification codes. The watering signal receiver 2 only controls the state of the solenoid valve 26 when it matches the identification code stored in its own memory. The operation is convenient.

[0030] For example, there is one watering signal transmitter, which stores three different first identifier codes: A01, A02, and A03. There are five watering signal receivers. Three of these receivers store the second identifier code A01 and are located in the same area of ​​the garden. The other two receivers store the second identifier codes A02 and A03, respectively, and are located in different areas of the garden. When people use the watering signal transmitter in their homes, they operate the first button panel, select the first identifier code A01, select the desired watering operation, and then send the watering signal outward by pressing the confirmation button. The first antenna broadcasts the watering signal outward. The second antennas of all five watering signal receivers receive the watering signal and extract the first identifier code A01 from it. Only the three watering signal receivers with the second identifier code A01 activate the solenoid valve to perform the watering operation; the other two receivers do not operate. People use a watering signal transmitter in their homes. They operate the first button panel, select the first identifier code A02, select the desired watering operation, and then send a watering signal outward through the first antenna by pressing the confirmation button. All five watering signal receivers extract the first identifier code A02 from the watering signal. Only the watering signal receiver with the second identifier code A02 will perform the watering operation, while the other four watering signal receivers will not work.

[0031] The first button panel 12 of the watering signal receiver 2 is easy for people to operate; the second button panel 22 of the watering signal receiver 2 is used for manually opening and closing the solenoid valve 26 or setting the identification code, etc.

[0032] Frequency Shift Keying (FSK) is one of the earliest modulation methods used in information transmission. Its main advantages are that it is relatively easy to implement and has good noise and attenuation resistance. Therefore, it has been widely used in medium and low speed data transmission.

[0033] The identification coding is a prior art technique. This utility model utilizes identification coding to achieve one-to-many selective control of garden watering.

[0034] Furthermore, the watering signal transmitter 1 also includes a first LCD display screen 15, which is electrically connected to the first MCU 11. The watering signal receiver 2 also includes a second LCD display screen 27, which is electrically connected to the second MCU 21. The LCD displays show the current operation.

[0035] Furthermore, the watering signal transmitter 1 also includes a first battery 16, which is electrically connected to the first MCU 11 and the modulation transmission circuit. The watering signal receiver 2 also includes a second battery 28, which is electrically connected to the second MCU 21, the demodulation receiving circuit, and the solenoid valve drive circuit 25. This invention is battery powered.

[0036] Furthermore, the solenoid valve 26 is a pulse solenoid valve. A pulse solenoid valve is a special type of solenoid valve used to control the flow of fluids or gases. It generates a pulse signal through a rapidly switching electromagnetic relay, causing the valve to open or close quickly, thereby achieving precise control of the fluid or gas.

[0037] In this embodiment, one watering signal transmitter can control multiple watering signal receivers. If the user stores the same identification code of the watering signal transmitter in multiple watering signal receivers at the same time, one watering signal transmitter can control multiple watering signal receivers at the same time. If each watering signal receiver stores a different identification code, the user can select the corresponding identification code on the watering signal transmitter and send a watering signal to select one of the multiple watering signal receivers to control the watering work.

[0038] A watering signal receiver can store up to three different identifier codes. These three different identifier codes are stored in three different watering signal transmitters, so a watering signal receiver can be controlled by different watering signal transmitters.

[0039] The following details the functions of this invention: This invention employs low-power FSK radio frequency modulation and demodulation technology. The watering signal receiver 2 activates the FSK demodulation receiving circuit 23 every second to detect the presence of a radio signal conforming to the encoding method. If a radio signal conforming to the encoding method is found, the data is demodulated and sent to the MCU for processing. When the watering signal transmitter 1 needs to send data commands to the watering signal receiver 2, it sends modulated data for more than one second to ensure the watering signal receiver 2 can correctly receive the data. This garden watering system features high real-time performance, high data transmission rate, strong anti-interference capabilities, and low power consumption. Both the watering signal transmitter 1 and the watering signal receiver 2 are battery powered, solving the problems of high power consumption requiring adapter power and limited application range associated with traditional radio frequency receivers.

[0040] The operation of this utility model is described in detail below: Before use, the watering signal transmitter 1 and the watering signal receiver 2 are registered and connected via code learning. The connection data is stored by the second MCU 21 of the watering signal receiver 2. During use, pressing the first button panel 12 of the watering signal transmitter 1 displays the operation corresponding to the button value on the first LCD. Simultaneously, the data is encoded, modulated by the FSK modulation transmission circuit 13, and transmitted. When the FSK demodulation receiving circuit 23 of the watering signal receiver 2 receives the data, it demodulates it into received data. The MCU of the watering signal receiver 2 compares the received data with the stored data to determine if it matches the transmitted data. If the data matches, the pulse solenoid valve is driven by the solenoid valve drive circuit 25 to open or close.

[0041] The second LCD of the watering signal receiver 2 is responsible for displaying the working status of the watering signal receiver 2; the second button panel 22 of the watering signal receiver 2 is used to perform setting operations of the watering signal receiver 2 or to manually open and close the solenoid valve.

[0042] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
