Abstract

A CPCI power supply based on data collection and monitoring is composed of a backboard connector, a redundancy control unit, a filter circuit unit, an isolation voltage conversion unit, an collectionamplification unit, an AD conversion unit, a temperature sampling unit, an MCU processing unit, an RS485 communication unit, an indicating lamp and a digital display unit. Double-path isolation voltage output has a redundancy function; a monitoring circuit on the board card monitors the voltage, the current and the temperature in real time, displays the voltage, the current and the temperature ona nixie tube in real time, and transmits the voltage, the current and the temperature to a host system for analysis and storage through an RS485 data communication channel; and an indicator light on the power panel displays operation and fault states.

Description

[0001] (1) Technical field: [0002] The invention relates to the field of CPCI (Compact PCI, compact PCI, PCI, Peripheral Component Interconnect, peripheral component interconnect standard) power supply, in particular to a CPCI power supply based on data acquisition and monitoring. [0003] (two) background technology: [0004] With the development of modern society, the requirements for computer reliability are getting higher and higher. Compact PCI is a high-performance industrial bus based on the PCI specification. It has greatly improved its structural and electrical reliability. It is widely used in industries with high reliability requirements such as aerospace, orbital signals, surveying and mapping, and medical treatment. [0005] The CPCI power supply is the key to ensure the stable operation of the entire system. To ensure the stable power supply requirements of the system, it is generally sufficient to provide the normal power supply voltage of the system and the st...
