[0022] The features and advantages of the present invention will become more readily understood through the following description with reference to the accompanying drawings, which are not drawn to scale and in which some features are exaggerated or minimized to show details of particular components:

[0023] Figure 1 It is the appearance assembly drawing of the debugging device of the present invention;

[0024] Figure 2 It is a circuit diagram of the debugging device of the present invention. DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present invention. It should be noted that the following detailed description of the present invention is only for the purpose of illustration, and is not intended to limit the present invention.

[0026] The present invention provides a debugging device and a debugging method for matching the speed of a driver and a motor of a single-tube product shooting control system, which are designed according to the control principle of the driver. The driver control circuit is mainly composed of a speed loop and a current loop. The speed loop receives an external speed setting and compares it with the speed feedback of the servo motor. The difference is amplified by proportional integration as a current setting and sent to the input end of the current loop. The current setting value and the current feedback value are compared and amplified. The analog voltage output by the current loop is sent to a pulse width regulator to be converted into a pulse signal with an amplitude corresponding thereto, and finally the corresponding AC voltage is output by the power component to drive the servo motor.

[0027] like Figure 1 As shown, a speed matching and debugging device for a shooting control system driver and a motor provided by the present invention includes a socket XS, a box body, and a debugging component arranged on the box body. The socket XS is used to connect the driver through a cable, and the driver and the servo motor are connected through an armature cable and a feedback cable.

[0028] like Figure 2 As shown, the debugging assembly includes a speed setting switch K1, a drive enabling switch K2, a pulse enabling switch K3, a double-pole double-throw switch K4, a speed adjustment potentiometer RP1, a first speed setting voltage test interface K5, and a second speed setting voltage test interface K6. These components can be arranged on a panel of the box body to facilitate the operation of the operator, and a mark for identifying the purpose of the component, such as Chinese characters, can also be marked at the corresponding position on the panel.

[0029] The connection relationship of the debugging component is as follows: the input end of the speed setting switch K1 is the positive power supply interface of the debugging device, and the output end is connected to the first fixed end of the speed adjustment potentiometer RP1; the second fixed end and the sliding end of the speed adjustment potentiometer RP1 are respectively connected to the two input ends of the double-pole double-throw switch K4; the two output ends of the double-pole double-throw switch K4 are respectively connected to the input ends of the first speed given voltage test interface K5 and the second speed given voltage test interface K6; the second fixed end of the speed adjustment potentiometer RP1 is the negative power supply interface of the debugging device.

[0030] The speed setting switch K1 can control the on and off of the input voltage of the power supply of the debugging device, and cut off the given voltage of the input driver under abnormal conditions. The speed adjustment potentiometer RP1 changes its internal resistance value by adjusting the position of the sliding end, thereby changing the current or voltage passing through the speed adjustment potentiometer RP1, so that the voltage between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 changes between 0V and 10V; the voltage between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured and displayed by a digital multimeter, so that the operator can adjust the given voltage in time to ensure accuracy; one output end of the double-pole double-throw switch K4 is connected to the sliding end of the speed adjustment potentiometer RP1, and the other output end is connected to the second fixed end of the speed adjustment potentiometer RP1. The output positive and negative poles of the given voltage are controlled by the double-pole double-throw switch K4, thereby controlling the forward and reverse rotation of the servo motor.

[0031] The socket XS has a first pin, a second pin, a third pin, a fourth pin and a fifth pin. The first pin is connected to the 24V voltage of the driver, the second pin is the output end of the drive enable switch K2, the third pin is the output end of the pulse enable switch K3, the fourth pin is the output end of the first speed given voltage test interface K5, and the fifth pin is the output end of the second speed given voltage test interface K6; the input ends of the drive enable switch K2 and the pulse enable switch K3 are both connected to the first pin.

[0032] Through the above five pins on the socket XS, the debugging component can be connected to the driver using a tooling cable. The driver's own 24V voltage enters the debugging device through the first pin, and is sent back to the driver through the drive enable switch K2 and the pulse enable switch K3 to control the driver to power on the servo motor. The drive enable switch K2 and the pulse enable switch K3 can control the internal circuit of the driver to enable the driver.

[0033] The debugging device designed in the present invention simulates the corresponding control signal of the upper computer, that is, the given voltage in the present invention, to match the speed of the driver and the servo motor before the driver and the servo motor are assembled to the equipment. The debugging device designed in the present invention is connected to the controlled driver using a tooling cable, and the driver is powered on and operated by the drive enable switch K2 and the pulse enable switch K3. The speed of the servo motor is matched by adjusting the given voltage, and the forward and reverse rotation of the servo motor is controlled by the double-pole double-throw switch K4.

[0034] A protective resistor R1 is connected between the speed setting switch K1 and the speed adjustment potentiometer RP1. By adjusting the current or voltage, the circuit of the debugging device is protected from damage. The protective resistor R1 needs to select a suitable power level according to the current size and power consumption.

[0035] The speed adjustment potentiometer RP1 is a potentiometer with a resistance value of 10KΩ, which can be used conveniently under normal temperature. The first speed given voltage test interface K5 and the second speed given voltage test interface K6 are connected to a digital multimeter to detect the voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6. The debugging device also includes a tachometer for measuring the speed of the output shaft of the servo motor, and matching the speed of the driver with the servo motor based on the speed of the output shaft of the servo motor.

[0036] The driver and servo motor are controlled units and actuators in the electrical system of the equipment. The driver receives the control signal from the host computer and responds accordingly to control the direction and speed of the servo motor, thereby driving the movement of mechanical parts.

[0037] like Figure 1 As shown, a speed matching debugging method for a shooting control system driver and a motor provided by the present invention is applied to a debugging device, comprising the following steps:

[0038] Step 1: First, connect the positive pole of the debugging device to +24V and the negative pole of the power supply to ground. Connect the debugging device to the driver through cables, and connect the driver to the servo motor through armature cables and feedback cables.

[0039] Step 2: Turn the double-pole double-throw switch K4 to the forward position, measure the voltage between the first speed given voltage test interface K5 and the second speed given voltage test interface K6, and adjust the speed adjustment potentiometer RP1 to make the measured voltage within the given voltage range, then make the potential energy of the driver drive the output shaft of the servo motor to rotate forward, and measure the first speed of the output shaft of the servo motor;

[0040] Step 3: According to the first speed, adjust the speed adjustment potentiometer of the driver to control the output voltage of the driver so that the driver and the servo motor reach the required matching speed;

[0041] Step 4: Turn the double-pole double-throw switch K4 to the reverse position, measure the voltage between the first speed given voltage test interface K5 and the second speed given voltage test interface K6, and adjust the speed adjustment potentiometer RP1 to make the measured voltage value within the given voltage range, then use the potential energy of the driver to drive the output shaft of the servo motor to reverse, and measure the second speed of the output shaft of the servo motor;

[0042] Step 5: According to the second speed, the speed adjustment potentiometer of the driver is adjusted to control the output voltage of the driver so that the driver and the servo motor reach the required matching speed.

[0043] Below, each step is described in detail.

[0044] In step 1, the debugging device is powered on and connected to the driver through a cable. The driver and the servo motor are connected through an armature cable and a feedback cable to form a debugging loop.

[0045] The specific steps of step 2 are: first turn the double-pole double-throw switch K4 to the forward position, at this time, the speed of the driver and the forward-rotating servo motor are matched, and then the speed adjustment potentiometer RP1 is adjusted to the minimum speed position, and the speed setting switch K1 is closed, and the voltage output is turned on to the driver. The first voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by a multimeter, which is 0V, to ensure that the output shaft of the servo motor does not rotate after power is applied, and then the drive enable switch K2 and the pulse enable switch K3 are closed, and then the speed adjustment potentiometer RP1 is slowly adjusted to the required position of the given voltage to make the servo motor speed change smoothly, and the second voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by a multimeter, which gradually approaches and reaches 10V, and the output shaft of the servo motor rotates forward under the potential energy drive of the driver, and finally the first speed of the output shaft of the servo motor is measured by a tachometer.

[0046] In step 3, the speed of the first speed at the second voltage value is measured to be 6000±30r / min, and the speed adjustment potentiometer of the driver is adjusted at this speed so that the speed of the driver also reaches 6000±30r / min.

[0047] The specific steps of step 4 are: first turn the double-pole double-throw switch K4 to the reverse position, at this time, the speed of the driver and the reversed servo motor are matched, and then the speed adjustment potentiometer RP1 is adjusted to the minimum speed position, and the speed setting switch K1 is closed. The first voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by a multimeter, which is 0V, and then the drive enable switch K2 and the pulse enable switch K3 are closed, and then the speed adjustment potentiometer RP1 is slowly adjusted to the required position of the given voltage, and the second voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by a multimeter, which gradually approaches and reaches 10V, and the servo motor output shaft is reversed under the potential energy drive of the driver, and finally the second speed of the servo motor output shaft is measured by a tachometer.

[0048] In step 5, the second speed at the second voltage value is the measured servo motor speed, and the speed adjustment potentiometer of the driver is adjusted according to the speed requirement index of 6000±30r / min, so that the matching speed of the driver and the servo motor also reaches 6000±30r / min.

[0049] The driver and the servo motor output shaft are adjusted to rotate forward and the servo motor output shaft is adjusted to match the speed. When the given voltage reaches 10V, the speed adjustment potentiometer of the driver is adjusted so that the matching speed of the driver and the servo motor reaches 6000±30r / min. The debugging device designed by the present invention is used to perform speed matching debugging of the driver and the servo motor to meet the use requirements and ensure the reliability of the product during subsequent debugging. At the same time, a detection and debugging means is provided for the maintenance of the driver and the servo motor of the subsequent corresponding after-sales products, which is consistent with the debugging method of the speed matching of the driver and the servo motor.

[0050] Finally, it should be noted that the features mentioned and / or shown in the above description of the exemplary embodiments of the present invention may be combined in the same or similar manner into one or more other embodiments, combined with the features in other embodiments or substituted for the corresponding features in other implementations. The technical solutions obtained by these combinations or substitutions shall also be deemed to be included in the protection scope of the present invention.
