Starting voltage testing method for all-digital follow-up system

Abstract

The invention relates to a starting voltage testing method for an all-digital follow-up system. A test bench, a servo controller and a power amplifier are adopted, wherein the test bench comprises a singlechip microcomputer with a display screen and a starting button; the singlechip microcomputer is electrically connected with the starting button; a voltage regulating value text frame and a voltage display frame are displayed on the display screen; when a number is input into the voltage regulating value text frame, a voltage value in a current state can be immediately displayed in the voltage display frame below the voltage regulating value text frame; every time the starting button is clicked, the voltage displayed by the voltage display frame is cumulatively increased by taking the number of the voltage regulating value text frame as an increment; the servo controller is electrically connected with the singlechip microcomputer, receives voltage digital quantity displayed by the voltage display frame of the test bench and sends the voltage digital quantity to the power amplifier; the input end of the power amplifier is electrically connected with the servo controller, and the output end of the power amplifier is electrically connected with a motor; the power amplifier can be a digital power amplifier or an analog power amplifier and drives the motor.

Description

technical field [0001] The invention belongs to a starting voltage testing method, in particular to a starting voltage testing method of an all-digital servo system of an optical cabin. Background technique [0002] At present, after the assembly of many optical chambers, the starting voltage of the test system is still manually tested, that is, the adjustable power supply is used to check whether the system can start when the voltage is gradually increased. This method is not accurate. The adjustable power supply voltage is in volts. The accuracy is 0.1 volts; the workload is cumbersome and can only be used in the most initial debugging state. When the whole system is assembled, especially after the high and low temperature experiments, it is necessary to test the starting voltage of the motor if there is a problem. Obviously, the manual test method in the past requires a lot of work such as disassembling the leads, which is not practical. Some people also use the CCS ram ...

[0002] At present, after the assembly of many optical chambers, the starting voltage of the test system is still manually tested, that is, the adjustable power supply is used to check whether the system can start when the voltage is gradually increased. This method is not accurate. The adjustable power supply voltage is in volts. Accuracy is 0.1 volts; the workload is cumbersome and can only be used in the most initial debugging state

When the whole system is assembled, especially if there is a problem after high and low temperature experiments, it is necessary to test the starting voltage of the motor. Obviously, the manual test method in the past requires a lot of work such as disassembling the lead wires, which is not practical.

Some people also use the CCS ram program to modify the value online to test the starting voltage. The problems of this method include: 1. The ram program cannot set a breakpoint in the case of a motor. Manual setting may cause errors, causing the program to run away and the motor to lose control. System or human body damage; 2. RAM memory is limited, if there are too many program codes, it cannot be tested online; 3. The accuracy is not enough, it is only a rough test, and it is necessary to manually calculate the motor voltage input
