Description

Technical Field

[0001] The invention relates to the field of electronics, and in particular to a dual power supply switching control system. Background Art

[0002] When using a capsule endoscope for stomach examination, the stomach is relatively large, so the capsule endoscope needs to be controlled for motion. The current common control method in the industry uses an external magnetic control device to control the movement of the magnet inside the capsule. In order to use it more conveniently and quickly, mobile robot magnetic control devices are the future development direction. The electric control system of the magnetic control device will provide power for the precise movement of the large magnet. The diversity of the electric energy properties of the electric control system determines the functional practicality of the magnetic control device system, especially when controlling circuits of different electric energy types and sizes such as AC / DC, high and low voltage, etc., the minimum electronic components and the simplest operation are required to achieve the required control functions.

[0003] Chinese patent application 2023113438225 provides a method for controlling a motor by switching between dual power supplies, which uses a main control chip to control a driving circuit to drive the motor.

[0004] Chinese patent application 2023112858633 provides a dual power supply management circuit capable of automatically switching the auxiliary power supply, which uses an MCU main control circuit to control the main power supply and the auxiliary power supply, thereby providing a stable power supply for the data acquisition terminal.

[0005] Both of the above-mentioned technical solutions use chips for power switching, which results in complex circuit design, high industrial manufacturing cost, and circuit stability that needs to be improved.

[0006] Therefore, it is necessary to design a dual power switching control system that is simple, efficient, circuit stable and low in cost. Utility Model Content

[0007] The present invention provides a dual power supply switching control system, and the specific technical solution is as follows:

[0008] A dual power switching control system includes a first circuit, a second circuit and a third circuit. The first circuit and the second circuit are controlled on and off by a switch, and the switch is a single-pole double-throw switch. The second circuit further includes a relay, and the relay controls the on and off of the third circuit according to the on and off of the second circuit.

[0009] Furthermore, the first circuit is an AC line provided by a grid power supply, and its circuit parameters are 220V / 10A.

[0010] Furthermore, the second circuit is a DC circuit provided by an internal power supply, and its circuit parameters are 5V / 45mA.

[0011] Furthermore, the third circuit is a DC line provided by an internal power supply, and its circuit parameters are 48V / 20A.

[0012] Furthermore, the electrical parameter of the switch is 250V / 10A.

[0013] Furthermore, the first circuit, the second circuit and the third circuit use any one of an AC line or a DC line or a combination thereof.

[0014] Furthermore, the relay is any one of a solid-state relay and a contactor.

[0015] Furthermore, the electrical parameter of the power switch is 10A.

[0016] The dual power switching control system of the present invention can control two lines of different power types and power sizes, such as AC / DC, high and low voltage, by utilizing the strong current-carrying capacity of the relay contact switch. One line directly controls the on-off of the AC line, and the other line indirectly controls the on-off of the DC line by controlling the relay coil loop. This can effectively solve the problem of switch current limitation that cannot be directly controlled by a small switch with a commonly used specification of 10A, thereby improving the flexibility of circuit design and the competitiveness of products. The system is particularly suitable for the electric control system of mobile robot magnetic control equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] refer to Figure 1 The schematic diagram of the dual power switching control system of the present invention, the dual power switching control system of the present invention comprises a first circuit S1, a second circuit S2 and a third circuit S3, the first circuit S1 and the second circuit S2 are controlled on and off by a switch K1, and the switch K1 is a single-pole double-throw switch; the first circuit S1 and the third circuit S3 are circuits that need to be controlled simultaneously.

[0020] The first circuit S1 is a power supply line provided by a grid power supply, which is an AC line with a voltage of 220V and a current of 10A.

[0021] The second circuit S2 is a control circuit provided by an internal power supply, which is a DC circuit with a voltage of 5V and a current of 45mA. The second circuit S2 serves as a control circuit of the third circuit S3 to control the on and off of the third circuit S3.

[0022] The third circuit S3 is a power supply circuit provided by an internal power supply, which is a DC circuit with a voltage of 48V and a current of 20A.

[0023] The second circuit S2 further includes a relay K2, which serves as a connecting device between the second circuit S2 and the third circuit S3. When the second circuit S2 is connected, the relay K2 works and the third circuit S3 is connected. Otherwise, the third circuit S3 is disconnected.

[0024] Furthermore, the switch K1 adopts the commonly used single-pole double-throw switch device specification of 250V / 10A. As a device that directly controls the on-off of the circuit, it can control two circuits with a voltage within 250V and a current within 10A, that is, control the on-off of the first circuit S1 and the second circuit S2.

[0025] Those skilled in the art will appreciate that the first circuit S1, the second circuit S2 and the third circuit S3 may use either an AC line or a DC line, and the relay K2 may be a solid-state relay, a contactor or any other power control device that achieves the same function.

Those skilled in the art will appreciate that the dual power switching control system of the present invention is not limited thereto.

[0027] Furthermore, the robot is either a fully automatic machine or a collaborative robot.

[0028] Furthermore, the switch K1 is a small switch rather than an industrial switch used in large equipment, which can effectively solve the switch current limitation problem that cannot be directly controlled by a small switch with a common 10A specification, and has a lower design cost and further improved reliability.

[0029] Furthermore, by using the dual power switching control system of the present invention, the power switch K1 uses a commonly used 10A single-pole double-throw switch and can be designed into different colors and shapes, using products produced by different manufacturers, which is more versatile and provides greater flexibility and reliability for the appearance of the whole machine and the supply of production materials.

[0030] Those skilled in the art can understand that the specific composition forms of the first circuit S1, the second circuit S2 and the third circuit S3 involved in the present invention belong to the common knowledge of ordinary technicians in the field, and the present invention does not limit this. As long as the design concept of the present invention is adopted to perform dual power supply switching control, it falls within the protection scope of the present invention.
