Description

Technical Field

[0001] This invention belongs to the field of power supply detection and aging management technology, specifically relating to a mobile DCS power supply automatic detection device. Background Technology

[0002] Traditional power supply testing requires disassembling the power supply and using multimeters, oscilloscopes, and other equipment to measure each component independently. Dedicated power supply testing devices can only test specific power supply models. Some general-purpose power supply testing platforms can only adjust the load and measure the power supply's output parameters by adjusting the output. However, the parameters measured are incomplete, the test items are fixed, and targeted testing is not possible. Therefore, they are of little reference value for power supply repair and aging management.

[0003] This device can not only detect changes in output load, but also detect power input and protection characteristics. In addition, in accordance with upstream regulatory requirements, it provides customized testing procedures for power supply spare parts acceptance, burn-in, periodic / aging testing, aging function verification, and post-repair evaluation, providing strong support for power supply maintenance and management. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile DCS power supply automatic testing device that designs selectable power supply test items based on the input parameters of the power supply under test, and, in accordance with regulatory requirements, performs tests on various input / output performance of the power supply under different conditions and generates corresponding reports and analysis results.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A mobile DCS power supply automatic testing device includes an industrial control computer that inputs the power supply information under test, formulates the test procedures, generates control commands, and controls other units to coordinate and complete the input / output / protection tests of the power supply under test, providing test reports and various statistical results. The device includes an AC test power supply and power supply circuit that provide various input parameter changes according to the host computer's commands; an electronic load and load circuit that provide various output load changes according to the host computer's commands; a system control unit that completes power protection action command changes according to the host computer's commands; and a power analyzer, input acquisition circuit, and sampling circuit that collect and feed back various input / output test results to the industrial control computer.

[0007] Input the relevant parameters of the power supply under test into the host computer, select the test items to be executed according to actual needs, and generate test instructions.

[0008] The AC power supply generates different input voltage / current signals according to the test instructions from the host computer, and generates different input signals through the power supply circuit to act on the power supply under test.

[0009] The input acquisition circuit transmits the relevant input measurement signals back to the host computer via the power analyzer to generate the corresponding test results.

[0010] The system control unit generates a protection action signal according to the test instructions from the host computer, which is applied to the power supply under test through the control loop and returned to the host computer through the sampling loop to form the test results of the relevant items.

[0011] The electronic load generates load conformity changes according to the test instructions from the host computer, which are applied to the power supply under test through the load circuit and returned to the host computer through the sampling circuit to form the test results of the relevant items.

[0012] The host computer generates the final power supply test reports and analysis results.

[0013] The beneficial effects achieved by this invention are as follows:

[0014] This invention can autonomously select appropriate test items based on input power parameters, regulatory requirements, and actual needs; test items can be combined autonomously; it achieves the detection of the power input part through an AC test power supply and a power analyzer and its circuit; and it realizes the detection of the power supply's protection function through the system control unit and its circuit.
