However, irrigation of rooftop gardens has always been a difficult problem. Traditional irrigation methods often suffer from uneven irrigation and water waste. To solve these problems, an intelligent irrigation system is needed that can achieve precise irrigation of rooftop gardens.

[0034] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0035] like Figure 1 and Figure 2 As shown, a smart irrigation system for rooftop gardens includes a smart irrigation controller, an irrigation module, a light sensor, a soil moisture sensor, a rainfall sensor, and supplemental lighting. The smart irrigation controller includes a waterproof box, three circuit boards, a transformer, a main switch, and a communication antenna. The three circuit boards are the main control board, the interface board, and the lighting board, respectively. The main control board and the interface board are the main control module and the interface module of the smart irrigation controller, respectively. The main control board is the core control board, housed in the waterproof box and connected to the main support frame via the waterproof box. The waterproof box has through-holes for cables connecting to the main control board, which are sealed with sealant to ensure the main control board's waterproofness. The main control board includes a microcontroller, a power management module, a communication module, a switch interface circuit, an indicator light interface circuit, a signal processing circuit, and an output drive circuit. The power management module, communication module, switch interface circuit, indicator light interface circuit, signal processing circuit, and output drive circuit are all electrically connected to the microcontroller, which can be a 51 series microcontroller or an STM32 microcontroller.

[0036] like Figure 2 and Figure 3 As shown, the interface board is equipped with a power interface, an input signal interface, and an output signal interface. The power interface is used to connect to an external power source. The input signal interface is electrically connected to the signal processing circuit, and the output signal interface is electrically connected to the output drive circuit. The power interface uses a 3-pin connector, including an ACL, ACN, and PE connector. The power interface is used to connect to a 220V external power source. The input terminal of the transformer is electrically connected to the power interface. The external power source connects to the transformer through the power interface. A main switch is located between the input terminal of the transformer and the power interface to control the on / off state of the circuit between the transformer and the power interface. The output terminal of the transformer is electrically connected to the power management module. The transformer steps down the 220V power supply to 24V, which is then supplied to the main control board through the power management module or power management circuit for use by the electrical components installed on the main control board.

[0037] like Figure 1 and Figure 2 As shown, the input signal interface is electrically connected to the signal processing circuit, as follows: Figure 4As shown, the input signal interface uses a 13P interface, which includes multiple sensor signal input interfaces. These sensor signal input interfaces use an RS-485 communication interface. The signal processing circuit is an RS-485 signal processing circuit. The input signal interfaces are electrically connected to the signal processing circuit via a PHB cable to transmit the sensor signals received by the sensor signal input interfaces to the signal processing circuit, and then to the microcontroller.

The light sensor transmits the light intensity at the roof garden to the microcontroller. The soil moisture sensor is placed in the soil of the roof garden to transmit soil moisture to the microcontroller. The rainfall sensor transmits the rainfall at the roof garden to the microcontroller.

[0038] Irrigation modules come in various structural forms. One typical structure includes a water tank, a water pump, an electrically controlled valve, and a water delivery pipeline. The water tank stores irrigation water, and the water pump delivers the water from the tank to the water delivery pipeline. The pipeline has multiple outlets, each equipped with a corresponding sprinkler head. The electrically controlled valve, located on the pipeline, controls the on / off state of the pipeline containing one or more sprinklers. In addition to the electrically controlled valve, manual valves can also be installed on the pipeline at appropriate locations as needed.

[0039] like Figure 2 As shown, the output signal interface is electrically connected to the output driver circuit, as follows: Figure 5 As shown, the output signal interface uses a 12-pin connector, including a 220V output interface and a 24V output interface. The 220V output interface is used to electrically connect to 220V electrical equipment, such as supplemental lighting and water pumps. The 24V output interface is used to electrically connect to 24V electrical equipment, such as electrically controlled valves and safety valves. The electrically controlled valves can be solenoid valves. The electrical equipment electrically connected to the output signal interface is controlled by the microcontroller. For example, the water pump and electrically controlled valve in the irrigation module are electrically connected to the output signal interface of the interface board, and thus controlled by the microcontroller. A flow meter is also installed on the water pipeline. The flow meter is electrically connected to the input signal interface of the interface board. The flow meter is used to provide feedback on the irrigation water volume to the microcontroller for precise control of the irrigation water volume. The supplemental lighting is electrically connected to the output signal interface of the interface board, thus connecting to the microcontroller.

[0040] In some exemplary embodiments, a liquid level sensor and a safety valve are also provided. The liquid level sensor is installed in the water tank and is communicatively connected to the interface module. The liquid level sensor is used to detect the liquid level in the water tank and transmit the liquid level signal to the main control module. The liquid level sensor can directly or indirectly achieve functions such as liquid level detection, automatic water replenishment, water shortage alarm, and leakage detection. The safety valve is installed on the water supply pipe between the water tank and the water pump suction port. The safety valve is electrically connected to the output signal interface of the interface board, thereby achieving electrical connection with the microcontroller and being controlled by the microcontroller.

[0041] like Figure 2 As shown, the intelligent irrigation controller also includes a light panel with indicator lights and an emergency stop switch. The indicator lights are electrically connected to the indicator light interface circuit, and the emergency stop switch is electrically connected to the switch interface circuit. The indicator lights include red, green, and blue lights. Different colors can be defined to indicate different operating states, such as a red light indicating a fault, a green light indicating normal operation and irrigation in progress, and a blue light indicating normal operation but no irrigation. This allows users to easily determine whether the invention and the irrigation system incorporating it are operating normally and in what state. The emergency stop switch can stop the system in case of a fault, improving safety.

[0042] like Figure 2 As shown, the main control board's communication module is a 4G module, and the communication antenna is a 4G antenna. The 4G module is connected to the 4G antenna via an SMA feeder. This allows the microcontroller to connect to the server via a 4G network signal and send data collected by various sensors to the server. Users can download and install a control app on their mobile phones, which is linked to the smart irrigation controller or a smart irrigation system with a smart irrigation controller. Users can then view various data collected by the sensors affecting plant growth in the rooftop garden, as well as the operating status of the smart irrigation controller and the smart irrigation system. Furthermore, a Bluetooth chip electrically connected to the microcontroller can be installed on the main control board of the smart irrigation controller. This allows the microcontroller to communicate with the control app on the user's mobile phone via Bluetooth, and the microcontroller can directly transmit data to the user's mobile phone via Bluetooth.

[0043] The control logic design of this utility model is as follows:

[0044] I. Irrigation Control Mode

[0045] (1) Manual irrigation control mode

[0046] The manual irrigation control mode is a mode in which the electric control valve is manually opened and automatically closed. When this mode is entered, the system will open the electric control valve according to the instruction and automatically close the electric control valve after the set stop time is reached, and then the system enters the standby state.

[0047] When the smart irrigation controller is in manual irrigation control mode, it must accept two control parameters, including:

[0048] Irrigation time: This parameter specifies the duration for which the electrically controlled valve is open. When the electrically controlled valve is opened, the system starts a countdown. When the set irrigation time is reached, the controller will send a shutdown command to close the electrically controlled valve.

[0049] Electrically controlled valve opening command: This parameter is the command for opening the electrically controlled valve in manual irrigation control mode. Upon receiving this command, the system will send an opening signal to the electrically controlled valve.

[0050] (2) Automatic control mode for timed and quantitative irrigation

[0051] In the automatic control mode of timed and quantitative irrigation, each electric control valve can be set to have 4 opening time periods as required. The electric control valve will periodically open to carry out irrigation according to the opening time periods.

[0052] When the intelligent irrigation controller is in the automatic control mode of timed and quantitative irrigation, each electrically controlled valve must receive three control parameters, including:

[0053] Irrigation time periods: Within a 24-hour period, four irrigation time periods are set for each electronically controlled valve, such as 1:00-2:00, 6:00-8:00, 15:00-17:00, and 19:00-20:00.

[0054] Irrigation cycle: can be set monthly, weekly, or by interval days, where:

[0055] ① The monthly setting allows irrigation to be carried out according to the odd or even date within the above-mentioned irrigation time period. The intelligent irrigation controller will perform irrigation on a monthly cycle. When the set date and irrigation time period are reached, the controller will open the electric control valve to complete the irrigation task.

[0056] ② Weekly setting allows users to select any day or multiple days from Monday to Sunday according to their needs. Irrigation tasks will be completed according to the above irrigation time period. When working in this mode, the intelligent controller will execute irrigation tasks on a weekly basis.

[0057] ③ The interval setting allows users to choose to perform irrigation tasks at intervals of one day or more, depending on their needs. When the interval date arrives, the system will activate the electrically controlled valve to perform irrigation according to the set time period. When operating in this mode, the intelligent controller will execute tasks at set time intervals.

[0058] Rainfall override: When rainfall override is enabled, if rainfall occurs within the set irrigation period and the rainfall exceeds the set value, the electrically controlled valve will not open during this irrigation period. Conversely, if this function of the intelligent irrigation controller project implementation plan is not enabled, the system will open the electrically controlled valve to perform the irrigation task according to the settings, regardless of whether there is rainfall.

[0059] (3) Intelligent irrigation control mode

[0060] In intelligent irrigation control mode, the controller will automatically execute irrigation tasks based on data from soil moisture sensors, rainfall sensors, and timers. In this mode, the electrically controlled valve will only open when both the soil moisture threshold and the irrigation time interval threshold meet the requirements.

[0061] When the smart irrigation controller is in smart irrigation control mode, each electrically controlled valve must receive three control parameters, including:

[0062] Soil moisture threshold: A soil moisture threshold is set. The electrically controlled valve will only open when the soil moisture level is below the set value. Irrigation will only commence when the irrigation time interval threshold is also met.

[0063] Irrigation interval threshold: Set the irrigation interval time. The electric control valve will only open when the irrigation time exceeds the set value and the soil moisture is lower than the set value.

[0064] Rainfall override: When rainfall override is enabled, if both the soil moisture threshold and irrigation interval threshold are met, and the rainfall exceeds the set value, the electronically controlled valve will not open. Conversely, if this function is not enabled, the electronically controlled valve will open to perform irrigation tasks according to the set logic, regardless of whether there is rainfall.

[0065] II. Safety Valve Control Mode

[0066] (1) Safety valve manual control mode

[0067] When the safety valve is in manual control mode, the system will open or close the safety valve according to manual instructions.

[0068] (2) Automatic control mode of safety valve

[0069] When the safety valve is in automatic control mode, the system will automatically close the safety valve and send an alarm message after detecting water leakage or excessive water.

[0070] When the smart irrigation controller is in the automatic safety valve control mode, it must accept two control parameters, including:

[0071] Minimum leakage threshold: This threshold indicates the minimum flow rate in the pipeline when the electrically controlled valve is closed. When the pipeline flow rate exceeds this flow rate, the safety valve will close to prevent leakage and overflow problems.

[0072] Excess water threshold: This threshold indicates the maximum total irrigation flow rate for the day. When the total irrigation flow rate exceeds this value, the safety valve will close.

[0073] When the safety valve is triggered and closed, the entire system switches to manual mode. After the fault is cleared, each system will switch back to automatic operation mode from manual operation. Otherwise, all system functions will remain in manual operation mode.

[0074] III. Fill Light Control Mode

[0075] (1) Manual control mode for fill light

[0076] When in manual control mode for the fill light, the system will turn the fill light on or off according to manual instructions.

[0077] (2) Automatic control mode for fill light

[0078] When in automatic fill light control mode, the system will turn the fill light on or off according to a preset time. This mode requires two control parameters, including:

[0079] Fill light activation time: When the set fill light activation time is reached, the system will automatically turn on the fill light.

[0080] Fill light off time: When the set fill light off time is reached, the system will automatically turn off the fill light.

[0081] IV. Water Pump Control Mode

[0082] (1) Manual control mode of water pump

[0083] When in manual pump control mode, the system will turn the pump on or off according to manual instructions.

[0084] (2) Automatic control mode of water pump

[0085] When in automatic pump control mode, the system will turn the pump on or off according to a preset time. This mode requires two control parameters, including:

[0086] Pump start time: When the set pump start time is reached, the system will automatically start the pump.

[0087] Pump shutdown time: When the set pump shutdown time is reached, the system will automatically shut down the pump.

[0088] In summary, this utility model is equipped with an intelligent irrigation controller, a light sensor, and supplemental lighting. The light sensor can transmit the light intensity of the roof garden to the intelligent irrigation controller. Based on the received light intensity signal and the internal settings, the intelligent irrigation controller can automatically control the supplemental lighting to supplement the light of the roof garden flowers when it is determined that the light is insufficient, so that the flowers in the roof garden will not be affected by insufficient light.

[0089] Furthermore, the intelligent irrigation controller of this utility model is equipped with a main control board and an interface board. The main control board is equipped with a microcontroller, and the interface board is equipped with an input signal interface for connecting various sensors. The interface board is also equipped with an output signal interface for connecting a precision irrigation device. The microcontroller can process the data from various sensors and automatically perform intelligent control of the precision irrigation device under the control of the control program, thereby achieving precise irrigation and effectively solving the problems of uneven irrigation and water waste.

[0090] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
