Intelligent automatic test system based on low-frequency circuit and test method thereof

Abstract

The invention discloses an intelligent automatic test system based on a low-frequency circuit and a test method thereof, the system comprises a test board, the surface of the test board is provided with a control panel, the bottom of the test board is fixedly connected with a bottom frame, and the diagonal position of the top of the test board is fixedly provided with a test box through a support frame, and the invention relates to the technical field of circuit test. According to the intelligent automatic test system based on the low-frequency circuit and the test method thereof, a circuit clamping mechanism is arranged, a cylinder is utilized to drive a piston rod to move, and the piston rod drives a connecting rod and a moving plate to move, so that a rotating rod between a first rotating block and a second rotating block is driven to rotate; according to the device, the two movable rotating shafts are driven to slide in the movable grooves, so that clamping points for testing can be adjusted, transmission clamping can be synchronously realized, the energy loss is reduced, meanwhile, direct contact of personnel is avoided, and the testing safety is enhanced.

Description

technical field [0001] The invention relates to the technical field of circuit testing, in particular to an intelligent automatic testing system based on low-frequency circuits and a testing method thereof. Background technique [0002] A measurement circuit is a circuit that measures the signal under test. In a multi-wire electrical tester, the circuit that uses a galvanometer to measure the potential difference is called a measuring circuit, and the measured potential difference can be obtained according to the following formula: △V=0.001Kic×R×L, where: Kic is the current constant (μA / cm) of the galvanometer system; R is the total resistance of the measurement circuit; L is the centimeter of light spot deflection. It is not difficult to see from the formula that the measurement circuit is mainly a set of precision resistors in addition to the galvanometer system to adapt to the range of the measured potential difference. [0003] Existing personnel also have the followin...
