Description

Technical Field

[0001] This utility model belongs to the field of agricultural electricity, specifically relating to a smart agricultural well power control system. Background Technology

[0002] In vast agricultural areas, especially in the north, irrigation is essential. Crops require irrigation from wells several times a year. However, due to the limited number of wells and the fact that each household charges separately for its pumps, a single well cannot be shared. During the busy farming season, farmers have to queue for irrigation, which is very inconvenient and can even delay the optimal irrigation time for crops, hindering agricultural development. Furthermore, the current metered billing system requires dedicated personnel to collect payments and then turn on the electricity to release water, wasting manpower and resources. Utility Model Content

[0003] This utility model provides a smart agricultural well power control system that uses a card reader or communication module for remote control of the controller. The controller controls the on / off of the well circuit, eliminating the need for a dedicated person to collect fees. Furthermore, a positioning module is used to locate the entire control system, preventing theft.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A smart agricultural well power control system includes a controller, a communication module, a positioning module, an electricity metering module, a temperature acquisition module, a card swiping module, a relay control module, and a control power supply module. The control power supply module supplies power to the controller, communication module, positioning module, electricity metering module, temperature acquisition module, card swiping module, and relay control module. The card swiping module, electricity metering module, temperature acquisition module, and positioning module are all electrically connected to the controller. The controller has a bidirectional communication connection with the communication module, and the controller controls the opening and closing of the normally open contacts of the AC contactor in the well power supply circuit through the relay control module. The relay control module includes a relay coil and a normally open relay contact. The controlled end of the relay coil is connected to the controller, and the normally open relay contact is connected to the AC contactor coil in the well power supply circuit. The communication module can receive remote commands and transmit collected information to a remote operating terminal. The temperature acquisition module collects the temperature of the environment in which the control system is located to avoid high temperatures affecting electrical safety. The card swiping module uses an RFID reader; after a card is swiped, the controller receives the card swiping signal and accordingly controls the relay control module to operate.

[0006] As a preferred embodiment of this utility model, the communication module is a 4G network module or an NB communication module.

[0007] As a preferred embodiment of this utility model, it also includes a touch screen, which is connected to the controller. The touch screen can send instructions to the controller on-site, and can also display the display information sent by the controller.

[0008] As a preferred embodiment of this utility model, the positioning module is a Beidou positioning module.

[0009] As a preferred embodiment of this utility model, it also includes an alarm module, which includes a buzzer alarm module, a vibration alarm module, and a flashing light alarm module.

[0010] As a preferred embodiment of this utility model, the electricity metering module is a timer or an energy meter; the timer is used to count the duration of electricity consumption, and the controller controls the relay to disconnect when the set time is reached; if an energy meter is used, the controller controls the relay to disconnect when the set amount of electricity is reached.

[0011] In a preferred embodiment of this utility model, the well power supply circuit includes a main well power supply circuit and a well power supply control circuit. The main well power supply circuit consists of an AC power source and normally open contacts of an AC contactor. The AC power source is a line output from the transformer to the well. The normally open contacts of the AC contactor serve as control switches on this line. The AC contactor coil is connected to the well power supply control circuit, which includes normally open contacts of a relay and an AC contactor coil. The normally open contacts of the relay are connected in series with the AC contactor coil. The relay coil is controlled by the controller to be energized. When energized, the normally open contacts of the relay close, energizing the AC contactor coil. This causes the normally open contacts of the AC contactor on the main well power supply circuit to close, thus powering the pump at the well and enabling it to start. When the controller de-energizes the relay coil, the normally open contacts of the relay open, de-energizing the AC contactor coil. This causes the normally open contacts of the AC contactor on the main well power supply circuit to open, thus de-energizing the pump at the well.

[0012] This utility model uses a controller to control whether the well is powered or not. It can be started by a card swipe module or remotely via a communication module. It also detects the ambient temperature of the control system and will cut off the power if the temperature is too high to protect the safety of the power supply system. The electricity metering module measures the electricity consumption, and the controller cuts off the power at the well when the set value is reached. Remote control does not require a dedicated person to cut off the power or charge the bill. Attached Figure Description

[0024] Example:

[0025] A smart agricultural well power control system, such as Figure 1 As shown, it includes a controller, a communication module, a positioning module, an electricity metering module, a temperature acquisition module, a card swiping module, a relay control module, and a control power supply module.

[0026] The circuit diagram of the control power module is as follows: Figure 9 As shown, the control power module supplies power to the controller, communication module, positioning module, electricity metering module, temperature acquisition module, card reader module, and relay control module. The controller uses a microcontroller, model STM32L072CBT6; the pin connection circuit of the microcontroller is as follows. Figure 2 As shown.

[0027] The card reader module, electricity metering module, temperature acquisition module, and positioning module are all electrically connected to the controller. The card reader module uses an RFID card reader, and the electricity metering module uses a timer in this embodiment. The circuit diagram of the timer is shown below. Figure 5As shown, it connects to the pins of the microcontroller; of course, the power metering module can also use an energy meter, which collects the power consumption of the well power supply circuit, and the controller controls the power consumption accordingly.

[0028] In this embodiment, the communication module uses an NB network module, and the circuit diagram is as follows. Figure 3 As shown, other network modules can also be used, as long as they can communicate bidirectionally with the controller, that is, receive remote commands and transmit them to the controller, and transmit the signals sent by the controller to the operating terminal.

[0029] The relay control module includes a relay coil and a normally open relay contact. The controlled terminal of the relay coil is connected to the controller, and the normally open relay contact is connected to the AC contactor coil in the well power supply circuit. The communication module can receive remote commands and transmit collected information to a remote operating terminal. The temperature acquisition module collects the ambient temperature of the control system to prevent high temperatures from affecting electrical safety. The circuit diagram of the temperature acquisition module is shown below. Figure 4 As shown; the card swiping module uses radio frequency scanning. After the card is swiped, the controller can receive the card swiping signal and control the relay control module accordingly.

[0030] To enable on-site operation and information display, a touchscreen is installed. The touchscreen is connected to the controller, allowing it to send commands to the controller and display information sent by the controller. The touchscreen's circuit diagram is shown below. Figure 8 As shown.

[0031] In this embodiment, the positioning module is a Beidou positioning module, and the circuit diagram is as follows. Figure 6 As shown, it is used to locate the entire system, and can know the location of the control system in real time. Even if it is stolen, the location information can still be obtained. The controller can also transmit the location information to the host computer or management terminal through the network module.

[0032] To provide a clear view of the control system's status, an alarm module is included. This alarm module comprises a buzzer alarm module, a vibration alarm module, and a flashing light alarm module. The specific circuit diagram is shown below. Figure 7 As shown.

[0033] The well power supply circuit consists of a main power supply circuit and a control circuit. The main power supply circuit comprises an AC power source and an AC contactor with normally open contacts (KM). The AC power source is a line output from the transformer to the well. The normally open contacts of the AC contactor act as control switches on this line. The AC contactor coil is connected to the control circuit, which includes a relay with normally open contacts (KM) and an AC contactor coil (JM). The relay with normally open contacts (KM) and the AC contactor coil (JM) are connected in series. The relay coil is controlled by the controller to be energized. When energized, the relay with normally open contacts closes, energizing the AC contactor coil. This energizes the AC contactor with normally open contacts on the main power supply circuit, allowing the pump at the well to receive power and start. When the controller de-energizes the relay coil, the relay with normally open contacts opens, de-energizing the AC contactor coil. This de-energizes the AC contactor with normally open contacts on the main power supply circuit, causing the pump at the well to lose power.
