[0026] The technical solution of the present invention is described in detail below through specific embodiments.

[0027] Example 1

[0028] like Figure 1-8 As shown, a circuit diagram of each part of a four-way water pump control system based on the ZigBee protocol in an embodiment of the present invention and a circuit principle schematic diagram are respectively given.

[0029] The four-way water pump control system includes an independently arranged power supply voltage stabilizing circuit, a four-channel ZigBee communication module and a four-channel relay output circuit.

[0030] The four-channel ZigBee communication module includes a four-channel ZigBee switch controller module, and a four-channel button control circuit and a mobile phone APP cloud connected to it. The four-channel button control circuit is the physical button end, and the mobile phone APP cloud is the remote mobile phone end. Both the button end and the mobile phone end can issue switch control instructions to the four-channel ZigBee switch controller module.

[0031] The four-channel button control circuit is connected to the four-channel ZigBee switch controller module in a one-way communication manner, that is, signals can only be sent from the four-channel button control circuit to the four-channel ZigBee switch controller module, but not in the reverse direction. The mobile phone APP cloud is connected to the four-channel ZigBee switch controller module in a two-way communication manner.

[0032] The four-channel button control circuit is provided with physical buttons. By pressing the physical button of the corresponding channel, a pulse signal can be sent to the four-channel ZigBee switch controller module, which outputs an open or close signal alternately. For example, the last time it is pressed, it is open, and the next time it is pressed, it is closed, and vice versa, thereby controlling the opening or closing of the corresponding channel.

[0033] There are cloud buttons and status display windows on the mobile phone APP cloud. Pressing the cloud button can send a signal to the four-channel ZigBee switch controller module to open or close the corresponding channel. At the same time, the four-channel ZigBee switch controller module will also send a signal to the mobile phone APP cloud, and the status of the four channels can be displayed on the status display window whether it is open or closed.

[0034] Users can observe the status of each channel in the status display window on the mobile phone APP cloud to understand whether each channel is currently open or closed, and then adjust it by operating physical buttons or cloud buttons.

[0035] The power supply voltage stabilization circuit includes a voltage regulator 1 and a voltage regulator chip 2 connected in series, wherein the voltage regulator 1 is a 12V-5VDC voltage step-down converter, and the voltage regulator chip 2 is an AMS1117-3.3V voltage regulator chip. The input end of the voltage regulator 1 is connected to an external power supply, and the output end is connected to the input end of the voltage regulator chip 2. The input end and the output end of the voltage regulator 1 are both grounded, and a first capacitor 3 is provided on the output end grounding line of the voltage regulator 1. The input end and the output end of the voltage regulator chip 2 are both grounded, and a second capacitor 4 is provided on the output end grounding line of the voltage regulator chip 2.

[0036] In the power supply voltage stabilization circuit, a 12V power supply is input, which is converted to 5V through a voltage reducer 1 and then used to provide power for subsequent circuits. After the 5V power supply passes through the voltage stabilization chip 2, it can provide stable power supply for the ZigBee module. The first capacitor 3 and the second capacitor 4 have the function of filtering and anti-interference, which can prevent voltage jitter and noise interference, and ensure that the circuit is more stable and reliable.

[0037] The four-channel key control circuit includes four key control circuits connected in parallel, each of which includes a first resistor 5 (10K resistor) and a switch key 6 connected in series, the switch key 6 is grounded, and the switch key 6 is a physical key. The output end of the power supply voltage stabilizing circuit is connected to the input end of the four-channel key control circuit, and can provide a voltage-stable power supply for the four-channel key control circuit.

[0038] The four-channel relay output circuit includes four independently arranged relay output circuits, and the four relay output circuits are all connected to the four-channel ZigBee switch controller module.

[0039] In the relay output circuit, an LED light emitting diode 7, a second resistor 8 (chip resistor 1K / 0603), a transistor 9 (NPN / S8050 / SOT23) and a third resistor 10 (1K) are connected in series in sequence. The output pin of the transistor 9 is grounded, and the output end of the relay output circuit is grounded. A fourth resistor 11 (chip resistor 2.7K / 0402 / 5%) is provided on the output end grounding circuit of the relay output circuit.

[0040] A relay 12 (W11-1A2STLE) is connected to the circuit between the second resistor 8 and the transistor 9. A diode 13 (IN4148 / LL34 cylindrical package) is connected in reverse parallel at both ends of the relay 12. The diode 13 can provide a discharge current loop for the self-induced electromotive force, and can provide continuous current to protect the circuit.

[0041] A socket 14 is provided behind the relay 12, specifically DA-804-5, and the water pump is connected to the relay output circuit via the socket 14. There are 4 water pumps in total, and each water pump is connected to 1 relay output circuit.

[0042] The four-channel ZigBee switch controller module includes four independently set switch buttons 6, namely K1, K2, K3 and K4, and four independently set IO ports L1, L2, L3 and L4.

[0043] The four switch buttons 6K1, K2, K3 and K4 in the four-channel ZigBee switch controller module correspond to the four switch buttons 6K1, K2, K3 and K4 in the four-channel button control circuit, and correspond to the four relays 12 in the four-channel relay output circuit. By pressing the four buttons in the switch button 6, the four relays 12 can be controlled to be turned on or off. The four IO ports L1, L2, L3 and L4 are connected to the input ends of the four independently set relay output circuits.

[0044] The four-channel ZigBee switch controller module also includes: (1) a VCC power input terminal connected to the output terminal of the power supply voltage stabilization circuit; (2) an LED display terminal for LED color indication; and (3) a ground terminal.

[0045] In the present invention, a physical button (four-channel button control circuit) and a mobile phone cloud button (mobile phone APP cloud) are provided in the four-channel ZigBee communication module, which can independently control the four-channel ZigBee switch controller module and the four-channel relay output circuit. When the mobile phone end or the button end issues an opening control command, the IO ports L1, L2, L3 and / or L4 in the four-channel ZigBee switch controller module will output a continuous high level, and the current will be amplified by the transistor 9 to drive the relay 12 of the corresponding channel to pull in, thereby opening the Lwire-Nwire output circuit (12V or 24V voltage), the power supply is turned on, and the back-end device of the corresponding channel, i.e., the water pump, is powered on and works.

[0046] Similarly, when the mobile phone or button end issues a shutdown control command, the IO ports L1, L2, L3 and / or L4 in the four-channel ZigBee switch controller module will output a continuous low level, and the transistor 9 will not detect the signal input, and will disconnect the relay 12, thereby closing the Lwire-Nwire output circuit, disconnecting the power supply, and the back-end device of the corresponding channel, i.e., the water pump, will be powered off and stop working.

[0047] The four switch buttons K1, K2, K3 and / or K4 can work independently and can turn on or off one or more of them at the same time. The four water pumps of the back-end equipment can be turned on or off one or more at a time, and the various control circuits do not interfere with each other.

[0048] When the hydroponic equipment needs water supply, turn on the switch button of the corresponding water pump through the physical button end or the mobile phone cloud, the water pump is powered on, and water can be provided to the hydroponic equipment; when water supply is not needed, turn off the switch button of the corresponding water pump, the water pump is powered off, and the water source is disconnected. Therefore, one power adapter can provide power to multiple water pumps at the same time, and multiple water pumps work independently and supply water separately.

[0049] Since it is equipped with a mobile phone terminal, the water pump can be easily controlled by the Internet of Things, can be remotely controlled, and can also be linked with other devices for easy use.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
