[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0019] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0021] like Figure 1 to Figure 2As shown, an intelligent circuit control device includes a controller, the controller includes an air switch, two AC contactors, two intermediate relays and a switching power supply; the switching power supply is provided with a plurality of switch buttons, the air switch controls two coils of the AC contactor, wherein the neutral line is electrically connected to the AC contactor, the live line is electrically connected to the intermediate relay, the air switch is electrically connected to the switching power supply, and the negative pole of the switching power supply is electrically connected to the intermediate relay, the voltage of the switching power supply is 12V, a soil sensor and an ambient temperature sensor are electrically connected to the controller, a single-chip microcomputer is electrically connected between the soil sensor and the ambient temperature sensor, the soil sensor is used to obtain soil moisture data, the ambient temperature sensor is used to measure the temperature of the environment, the single-chip microcomputer is electrically connected to the intermediate relay, an ultrasonic sensor and an alarm component are electrically connected to the controller, the AC contactor has two inputs and outputs, and the two paths can be interlocked, one path can be open and the other path can be closed, or both can be opened, the switch is 12V weak current, the controller is electrically connected to an intelligent control component, and the intelligent control component is provided with a data acquisition component and a data storage library.

[0022] In specific use, the main function of the controller is to control all circuits in the same field through one device, and to realize the forward and reverse interlocking function of the motor. The AC contactor in this device has two inputs and outputs, and the two can be interlocked (interlocking is one way open and the other closed), and can also be opened at the same time. The switch is 12V weak current, which is safer to use.

[0023] Design plan: Taking KM1 as an example, the air switch takes power in two ways. One way controls the two coils of the AC contactor. The neutral line is directly connected to the A1 port of the AC contactor KM 1. The live wire passes through the intermediate relay control circuit and then returns to the A2 port of KM 1 via the NC line of KM2 (normally closed, the circuit is closed when the coil cannot be energized). The air switch provides power to the switch, which is output as 12V weak current. The negative pole of the switch power goes directly into the 13th port of the intermediate relay KA1, and the positive red wire goes into the normally closed circuit of the close button, and then goes into the 14th port of the intermediate relay KA after being connected to the normally open circuit of the open button. Use the red wire to connect the closed 2 points with the 4 points of the intermediate relay, and use a wire to short-circuit the intermediate relay 6 and 14 to complete the self-locking connection of the intermediate relay.

[0024] When the open button is pressed, the coil 13-14 of the intermediate relay is energized, and the AC contactor controlled by the intermediate relay changes from normally open to closed state. The main circuit enters the AC contactor A2 through the intermediate relay, and the main contacts of the AC contactor are closed, the life circuit is connected, and the intermediate relay of the control part is self-locking and keeps energized. At this time, turn on another button, KM2 is not energized, and its A2 port circuit passes through the NC port of KM1 (the NC port is in the disconnected state at this time). When the close button is pressed, the 14th port of the intermediate relay KA1 is energized, the KA1 coil 13-14 loses power, the KM1 circuit is disconnected, and the production circuit is closed. The control principle of KM2 is the same as that of KM1 and will not be described again. If there are multiple electrical appliances, install them according to whether self-locking is required.

[0025] In the intelligent control part, we obtain soil moisture data through soil sensors and ambient temperature sensors through ambient temperature. The soil moisture and ambient temperature thresholds written into the single-chip computer control the high and low level conversions to trigger the high-level relay switch. The high-level relay replaces the intermediate relay KA1 or KA2 of the basic part to control the AC contactor KM 1 or KM2. The relay circuit controls the basic part to realize intelligent circuit control. The ultrasonic sensor tests the distance. When someone approaches a certain area, the distance threshold and predetermined conditions are written into the single-chip computer to control the voice module to issue an alarm command, thereby realizing the alarm function when people or objects reach the predetermined area. The single-chip computer interacts with the connected mobile phone or computer and platform through 5G or WIFI to realize intensive management and data analysis.

[0026] Control function: The main function is to control all circuits in the same venue through one device, and can realize the forward and reverse interlocking function of the motor. The AC contactor in this device has two inputs and outputs, and the two can be interlocked (interlocking is one way open and the other closed), and can also be opened at the same time. The switch is 12V weak current, which is safer to use.

[0027] Design plan: Taking KM1 as an example, the air switch takes power in two ways. One way controls the two coils of the AC contactor. The neutral line is directly connected to the A1 port of the AC contactor KM 1. The live wire passes through the intermediate relay control circuit and then returns to the A2 port of KM 1 via the NC line of KM2 (normally closed, the circuit is closed when the coil cannot be energized). The air switch provides power to the switch, which is output as 12V weak current. The negative pole of the switch power goes directly into the 13th port of the intermediate relay KA1, and the positive red wire goes into the normally closed circuit of the close button, and then goes into the 14th port of the intermediate relay KA after being connected to the normally open circuit of the open button. Use the red wire to connect the closed 2 points with the 4 points of the intermediate relay, and use a wire to short-circuit the intermediate relay 6 and 14 to complete the self-locking connection of the intermediate relay.

[0028] When the open button is pressed, the coil 13-14 of the intermediate relay is energized, and the AC contactor controlled by the intermediate relay changes from normally open to closed state. The main circuit enters the AC contactor A2 through the intermediate relay, and the main contacts of the AC contactor are closed, the life circuit is connected, and the intermediate relay of the control part is self-locking and keeps energized. At this time, turn on another button, KM2 is not energized, and its A2 port circuit passes through the NC port of KM1 (the NC port is in the disconnected state at this time). When the close button is pressed, the 14th port of the intermediate relay KA1 is energized, the KA1 coil 13-14 loses power, the KM1 circuit is disconnected, and the production circuit is closed. The control principle of KM2 is the same as that of KM1 and will not be described again. If there are multiple electrical appliances, install them according to whether self-locking is required.

[0029] In the intelligent control part, we obtain soil moisture data through soil sensors and ambient temperature sensors through ambient temperature. The soil moisture and ambient temperature thresholds written into the single-chip computer control the high and low level conversions to trigger the high-level relay switch. The high-level relay replaces the intermediate relay KA1 or KA2 of the basic part to control the AC contactor KM1 or KM2. The relay circuit controls the basic part to realize intelligent circuit control. The ultrasonic sensor tests the distance. When someone approaches a certain area, the distance threshold and predetermined conditions are written into the single-chip computer to control the voice module to issue an alarm command, thereby realizing the alarm function when people or objects reach the predetermined area. The single-chip computer interacts with the platform through 5G or WIFI to realize intensive management and data analysis.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
