Problems solved by technology

Due to the large amount of equipment involved in the testing process, manual operation of the equipment and data recording is not only inefficient, but also prone to errors, affecting product quality
[0003]The current secondary power supply circuit test system can realize automatic test and channel switching function, but the resistance characteristic test of the tested product and the test equipment, the tested The safety monitoring of the circuit has not been clearly stated. During the resistance test of the secondary power supply circuit, there is a charging and discharging process in the internal circuit, so the test time cannot be fixed and there is no unified judgment standard for whether the test results are stable; the input voltage of the secondary power supply and The load capacity has a certain range. If the power supply / load is abnormal or the secondary power supply fails during the test, the test safety will be threatened.

Abstract

The invention relates to an intelligent testing system and method for secondary power supply circuits, belongs to the technical field of secondary power supply circuit testing, and is used for automatically testing a plurality of secondary power supply circuits at the same time. The testing system realizes the real-time monitoring, recording and diagnosis of a device operation state, acquires theoutput state information of an incubator, a power supply and a load in real time, displays, updates and stores the information in real time for analyzing and tracing the influence of the device outputstate on a product performance index, and performs closed-loop control on the device; meanwhile, the testing system compares the device state information with an abnormal mode, thereby achieving therecognition, alarm and processing of an device operation fault in the testing process, and achieving the protection to a product and the device.

Description

technical field [0001] The invention relates to an intelligent testing system and method for a secondary power supply circuit, which belongs to the technical field of secondary power supply circuit testing and is used for simultaneous automatic testing of multiple secondary power supply circuits. Background technique [0002] The secondary power circuit test system is a necessary tool for the adjustment and testing of the secondary power circuit. The test of the secondary power supply circuit generally uses equipment such as a thermostat, power supply, load, multimeter, and oscilloscope to conduct a resistance test and output voltage test on the secondary power supply circuit under full temperature conditions. During the test, the test equipment needs to be controlled. , so that it meets the test process requirements. Due to the large amount of equipment involved in the testing process, it is not only inefficient to manually operate the equipment and record data, but also p...
