Problems solved by technology

[0007] 3. The compatibility of this power screen monitoring system is insufficient, and it is impossible to test various power modules from multiple manufacturers. The biggest problem facing the power screen detection platform now is that there is no unified, exact definition, executable, and targeted design codes and standards
Therefore, the biggest problem facing the current detection of power screens is that there are too many modules, and the interface methods of each manufacturer are different.

Embodiment

[0033] A working method based on an embedded general test platform for power modules, such as figure 1 As shown, the test platform includes an embedded control system, a single-chip microcomputer control board and a meter sensor, wherein the embedded control system exchanges data with the single-chip microcomputer control board through the RS-232 The embedded control system adopts SUMSANG S5PV210 main chip, which can quickly process data and run programs. Its main function is to send control commands and recover the data returned by the meter sensor and the single-chip control board, and use it for storage. The electrical signal data of the power supply is convenient for detection; the single-chip control board contains two 8051 single-chip microcomputers, and the closing and opening of the relay and the contactor are controlled by the high and low levels of the single-chip I / O pins, and the test pins of the power module under test are short-circuited. Control different power ...

Abstract

A working method of an embedding-based power module general testing platform belongs to the technical field of intelligent detection of the power module of a power supply panel. Stable working of the power supply module of the power supply panel is one of the premises of guaranteeing reliable and stable operation of power supply, while whether the power supply module can stably output appropriate power signals is the data which must be detected for power supply control. The embedding-based power module general testing platform is composed of an embedded control system, a single chip microcomputer control panel and a gauge sensor, wherein the embedded control system achieves output of electric signals to be detected of the power supply module through the single chip microcomputer control panel, and the gauge sensor collecting the electric signal data of the power supply module by receiving the instruction of the embedded control system and feeds the electric signal data back to the embedded control system; the embedded control system can complete monitoring on the electric signal data of DC (direct current) or AC (alternate current) voltage, current and power factors of the power supply module inside the power supply panel. The embedding-based power module general testing platform has the advantages of being stable, high in compatibility, low in complexity and the like.

Description

technical field [0001] The invention relates to a working method based on an embedded universal test platform of a power supply module, and belongs to the technical field of intelligent detection of a power supply module of a power supply screen. Background technique [0002] With the rapid development of science and technology, the power supply, as the core product of the electrified information society, has greatly promoted the development of the informatization of the electrical signal system and the update of the power screen equipment. At the same time, higher requirements are put forward for the power supply. The basic requirements of signal equipment for power supply are: reliable, stable and safe. In order to make the power supply more available, the power supply standard of the Ministry of Railways stipulates the value of the output voltage fluctuation range of the signal power supply and the allowable range of the AC frequency fluctuation. The power supply equipm...
