[0002] In modern electronic devices, it is often necessary to process different types of signals. For example, in motor control systems, there are voltage signals from sensors that are used to feedback the motor status, as well as control signals for controlling the motor's rotation angle. These signals are based on different physical quantities and representation forms and need to be converted to each other to achieve effective system control.

[0004] In some application scenarios, the acquisition and processing of angle information is crucial. For example, in the joint control of a robotic arm, the rotation angle of the joint needs to be accurately measured and controlled. The angle sensor may output a digital angle signal or an analog voltage signal related to the angle. In the system's control unit, other voltage signals may need to be converted into corresponding angle signals for precise position control. Conversely, in some measurement systems, angle changes need to be converted into voltage signals for further signal processing, transmission, and storage.

[0035] First embodiment

[0036] Please refer to Figure 1 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a voltage-to-angle conversion circuit provided by the present invention. A voltage-to-angle conversion circuit includes:

[0037] A power supply 6, wherein the delivery end of the power supply 6 is connected to two switches 1 via an electric wire, and the delivery ends of the two switches 1 are both connected to a digital voltmeter 2 via a connecting wire;

[0038] Multiple sampling lines 5, each of which is connected to the delivery ends of the two digital voltmeters 2, one end of each of the sampling lines 5 is connected to a potentiometer 4, and the delivery end of the potentiometer 4 is connected to a sampling resistor 3 via a wire;

[0039] The signal device 7 is connected to one end of the sampling resistor 3 via a connecting line.

[0040] Sampling resistors 3 are connected to both sides of the potentiometer 4 through wires. The two sampling resistors 3 are connected through wires.

[0041] The digital voltmeter 2 is used to display the angle signal in the form of voltage value.

[0042] The sampling circuit 5 is used to transmit the calculated voltage angle signal.

[0043] The potentiometer 4 is used to adjust the accuracy.

[0044] The required sampling circuit 5 is composed of precision resistors and potentiometers. By changing the input of multiple high-precision voltages, the angle display can be flexibly realized, and miniaturization is easy to achieve.

[0045] The voltage solution is a linear angle display. When measuring, you only need to operate the switch to turn on the working power supply and input multiple high-precision voltage-type angle signals to complete the direct measurement and display of the angle corresponding to the voltage value. The displayed value directly displays multiple angle values ​​with a small voltage, and different angle values ​​can be displayed by changing the input of high-precision voltage-type angle signals of different amplitudes. By changing the size of the sampling resistor, the voltage-type angle values ​​with different mathematical relationships can be displayed.

[0046] Digital voltmeter 2 is a ±200mv digital voltmeter.

[0047] The proportional resistors of the solving circuit are 60K ohms and 500 ohms respectively. The adjustment potentiometer is used to adjust the accuracy, and the resistance value of the adjustment potentiometer is 500 ohms.

[0048] The pitch and tilt input voltage signal is 0.000V, and the corresponding angle signal displays 0°;

[0051] Accuracy error: 0° not greater than ±0.06°, 30° not greater than ±0.1°, and 30° not greater than ±0.2°.

[0052] The working principle of a voltage conversion angle circuit provided by the utility model is as follows:

[0053] During use, when the power supply 6 is powered on, 220V AC current flows to the switch 1 through the wires. When the 220V AC current flows to the switch 1, the switch 1 then supplies the 220V AC current to the digital voltmeter 2. When the digital voltmeter 2 is powered on, the digital voltmeter 2 enters the working mode. At the same time, 220V AC current also flows to the sampling resistor 3 and the potentiometer 4 through the wires. When the current flows into the sampling resistor 3 and the potentiometer 4, the sampling resistor 3 and the potentiometer 4 settle and divide the input voltage angle signal, and transmit the resolved voltage angle signal to the digital voltmeter 2 through the sampling line 5. The digital voltmeter 2 displays the angle signal in the form of a voltage value.
