[0016] The present invention is described below in conjunction with the accompanying drawings. The specific implementation methods described here are only used to illustrate and explain the present invention and are not used to limit the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solution of the present invention by ordinary technicians in this field should fall within the scope of protection of the present invention.

[0017] like Figures 1 to 7 As shown, the orchard environment remote monitoring system of this embodiment includes a medicine storage tank, a water storage tank, a temperature and humidity sensor, a network camera, a PLC controller, a network module, a water pump, a water pipe, a sprinkler and a mobile terminal.

[0018] Generally, there are pesticide storage tanks and water storage tanks in the orchard to facilitate the staff to obtain pesticides and clean water.

[0019] There are multiple temperature and humidity sensors evenly arranged in the soil of the orchard, and the temperature and humidity values ​​of the orchard soil are collected by the temperature and humidity sensors.

[0020] There are multiple network cameras evenly distributed in the orchard, and the environmental conditions of the orchard are photographed through the network cameras.

[0021] The PLC controller is electrically connected to multiple temperature and humidity sensors respectively, and the signal output ends of the temperature and humidity sensors are electrically connected to the signal input ends of the PLC controller. The temperature and humidity sensors send detection signals to the PLC controller, and the PLC controller converts the detection signals into temperature and humidity values. In the circuit diagram, the number of temperature and humidity sensors is 2. This number is only for reference, but does not mean that the system has only 2 temperature and humidity sensors.

[0022] The network module is connected to the PLC controller, network camera, and mobile terminal. In this embodiment, the network module utilizes a router. A network is deployed in and around the orchard. When powered on, the router can connect to the network and generate a WiFi signal. The mobile terminal in this embodiment is a PC or smartphone, with the PC being a laptop. The PLC controller's network port is connected to the router via a network cable, enabling the PLC controller to connect to the network and thereby wirelessly communicate with the mobile terminal. An operator can use the mobile terminal to issue commands to the PLC controller via the wireless network, thereby achieving remote control of the PLC controller.

[0023] This embodiment of the network camera is a next-generation product that combines traditional cameras with network video technology. In addition to possessing all the image capture functions of a conventional camera, it also features a built-in digital compression controller and a web-based operating system. This allows compressed and encrypted video data to be delivered to end users via a local area network, the internet, or a wireless network. The network camera can connect to a router's WiFi signal to establish a network connection. A mobile terminal with a monitoring client for the corresponding network camera is installed. The operator can add the device and configure the appropriate settings in the client's management interface to establish a wireless connection between the mobile terminal and the network camera. The operator can then monitor the camera's footage by simply opening the client.

[0024] At least two water pumps are provided, both electrically connected to a PLC controller, and the operation of the water pumps is controlled by the PLC controller. The at least two water pumps are evenly arranged beside the medicine storage tank and the water storage tank. The water inlet of the water pump located beside the medicine storage tank is connected to the medicine storage tank via a water pipe, and the water outlet is connected to a nozzle via a water pipe. The nozzle is located beside the fruit tree and sprays pesticides through the nozzle. The water pump located beside the water storage tank is connected to the water storage tank via a water pipe, and the water outlet is connected to a nozzle via a water pipe. The nozzle is located beside the fruit tree and sprays clean water through the nozzle to moisten the soil or replenish water for the fruit tree. In addition, the water pipe connected to the water outlet of the water pump includes a main pipe and multiple branch pipes. One end of the main pipe is connected to the water outlet of the water pump, and the other end is connected to one end of multiple branch pipes. The other end of the branch pipe is connected to a nozzle. A solenoid valve is provided on the pipeline of each branch pipe, and the solenoid valve is electrically connected to the PLC controller. After starting the water pump, the PLC controller controls the solenoid valve on the corresponding branch pipe to conduct, allowing the branch pipe to conduct and spraying pesticides or clean water accordingly. This allows for targeted use without wasting resources. In addition, a water pressure sensor is installed on the main pipe, which is electrically connected to the PLC controller. The water pressure sensor can detect the water pressure at the water outlet of the water pump. The PLC controller converts the detection signal into a pressure value, which can be sent to the mobile terminal via the network module. In the circuit diagram, there are two water pressure sensors. This number is for reference only and does not mean that the system only has two water pressure sensors.

[0025] The orchard environment remote monitoring system of this embodiment also includes a power supply module, which includes a 220V AC power supply and a switching power supply. The L and N terminals of the switching power supply input are electrically connected to the L and N terminals of the 220V AC power supply, respectively. The output terminal of the switching power supply can output a 24V DC voltage and a 5V DC voltage. The router, network camera, and water pump are powered by the 220V AC power supply, and the remaining components are powered by the output terminal of the switching power supply. The power supply module also includes a rocker switch and a fuse FU1. The rocker switch is used to connect and disconnect the power supply, and the fuse FU1 is used to protect the circuit.

[0026] In this embodiment, relays are electrically connected between the water pump and solenoid valve and the PLC controller. These relays drive the water pump and solenoid valve. In the circuit, the water pumps are represented by D1, D2, ..., Dn, the relays are represented by KA1, KA2, ..., KAn, and the solenoid valves are represented by M1, M2, ..., Mn. Taking water pump D1 as an example, the output terminal Q1.0 of the PLC controller is electrically connected to the positive pole of the coil of relay KA1, the negative pole of the coil of relay KA1 is electrically connected to the GND terminal, the normally open terminal of relay KA1 is electrically connected to the L terminal of the 220V mains power supply, the common terminal is electrically connected to the power supply terminal L of water pump D1, and the power supply terminal N of water pump D1 is electrically connected to the L terminal of the 220V mains power supply. When the output terminal Q1.0 of the PLC controller outputs a signal, the coil of relay KA1 is energized, and the normally open terminal of relay KA1 is closed. At this time, the power supply terminal of water pump D1 is turned on and begins operation. When the PLC controller does not output a signal, relay KA1 is turned off. The circuit connection method of other water pumps is the same as that of water pump D1.

[0027] Taking solenoid valve M1 as an example, the PLC controller's output terminal Q1.3 is electrically connected to the positive pole of the relay KA4 coil, the negative pole of the relay KA4 coil is electrically connected to the GND terminal, the normally open terminal of relay KA4 is electrically connected to the positive pole of the 24V DC voltage output terminal of the switching power supply, the common terminal is electrically connected to the positive pole of the solenoid valve M1 power supply terminal, and the negative pole of the solenoid valve M1 power supply terminal is electrically connected to the GND terminal. When the PLC controller's output terminal Q1.3 outputs a signal, the relay KA4 coil is energized, and the normally open terminal of relay KA4 closes. At this time, the solenoid valve M1 is conductive, and the branch pipe is conductive. When the PLC controller does not output a signal, relay KA4 is not conductive. The circuit connection method for other solenoid valves is the same as that of solenoid valve M1.

[0028] In addition, the system also includes control buttons for controlling the operation of the water pumps and solenoid valves. The control buttons are electrically connected to the PLC controller. Each water pump is connected to a corresponding control button, and each solenoid valve is connected to a corresponding control button. In the circuit, the control buttons for controlling the water pumps are represented by KD1, KD2, ..., KDn, and the control buttons for controlling the solenoid valves are represented by KM1, KM2, ..., KMn. This allows not only the mobile terminal to send instructions to the PLC controller through the network module to control the operation of the water pumps and solenoid valves, but also the control buttons can be used on-site to control the operation of the water pumps and solenoid valves.

[0029] Water level sensors are installed inside the water tank and the medicine tank. The water level sensors are electrically connected to the PLC controller. The two water level sensors detect the water levels of the liquids in the water tank and the medicine tank, respectively, and send the detection signals to the PLC controller. The PLC controller converts the detection signals into water level values ​​and sends the corresponding water level values ​​to the mobile terminal. The staff can check the water levels in the water tank and the medicine tank through the mobile terminal and replenish the liquid in the corresponding tank in time according to the water level values. In the circuit diagram, the number of water level sensors is 2, which is only for reference and does not mean that the system has only 2 water level sensors. The temperature and humidity sensor, water pressure sensor, and water level sensor of this embodiment are all existing technologies and are common sensors in life.

[0030] In addition, the system also includes a touch screen electrically connected to the PLC controller. The PLC controller and the touch screen are connected via an RJ45 interface. The touch screen can send instructions to the PLC controller and display the values ​​detected by each sensor.

[0031] The operating principle of this system is: the temperature and humidity of the orchard soil can be detected through multiple temperature and humidity sensors, and the detection signals are sent to the PLC controller and converted into temperature and humidity values. The environment of the orchard can be monitored through the network camera. Since the PLC controller and the network camera are both connected to the mobile terminal through the network module, the temperature and humidity values ​​and the video images taken by the network camera can be sent to the mobile terminal through the network module. The staff can remotely monitor the soil temperature and humidity and the environment of the orchard through the mobile terminal; in addition, the mobile terminal is used to send instructions to the PLC controller through the network module. The PLC controller controls the operation of the water pump and the solenoid valve according to the instructions, thereby achieving the purpose of remote control of the operation of the water pump and the solenoid valve. The water pump sprays the fruit trees by extracting pesticides or clean water from the medicine storage tank or water storage tank, which prevents pests and replenishes water to the fruit trees or soil. Compared with manual spraying of pesticides and replenishing water, this system greatly reduces labor costs. When the humidity sensor at a certain location registers low humidity, staff can activate a nearby solenoid valve and a connected pump to replenish water. Furthermore, staff can control the corresponding pumps and solenoid valves using buttons and a touchscreen while on-site at the orchard. A water pressure sensor monitors the water pressure in the pipes, while a water level sensor monitors the water levels in the two tanks. The pressure and level values ​​generated by the PLC controller are displayed on the touchscreen and transmitted to a mobile device via a network module.
