State monitoring system based on single-chip microcomputers

Abstract

The invention discloses a state monitoring system based on single-chip microcomputers. The state monitoring system comprises an interface board single plate and multiple service board single plates. Each single plate comprises a single-chip microcomputer processor, a current acquisition circuit, a voltage and temperature acquisition circuit, an I2C interface, a GPIO interface and an analog I2C interface. The interface board single plate further comprises an RS 485 interface. A distributed master-slave communication structure is adopted in the state monitoring system, an interface board single-chip microcomputer serves as a master computer, service board single-chip microcomputers serve as slave computers, and the single plates are distinguished by being configured with ID numbers. The interface board single-chip microcomputer is used for collecting state information of each single plate, enables each single plate to be in communication with a host computer and an external master control unit in a uniform mode, and state parameters like the power voltage, the current, the core chip temperature of each single plate and external chip work clocks in a whole machine can be monitored in real time. The state monitoring system has the advantages of being complete in detection, simple in external interface, uniform in configuration item, high in generality, good in real time performance, and the like.

Description

technical field [0001] The invention relates to a state monitoring system based on a single-chip microcomputer, in particular to a state monitoring system suitable for multi-board cooperative operation. Background technique [0002] The task of condition monitoring is to understand and grasp the operating status of the equipment during the operation of the equipment or without disassembly, and to evaluate the current operating status of the equipment by using various detection, monitoring, analysis and discrimination methods, and to judge its status. Normal state, abnormal state or fault state, lays the foundation for subsequent fault location and fault diagnosis. [0003] In the case of multiple boards working together in the system, it is necessary to monitor the status of each board and centrally manage the monitoring results, which requires the use of distributed monitoring technology. After reviewing relevant literature on monitoring system voltage, current, temperatur...
