Abstract

The invention discloses a single board information monitoring device and a distributed single board information monitoring system. The device comprises a monitoring device, a monitoring unit and a main central processing unit (CPU), wherein the monitoring device is used for collecting environment information of a device on a single board; the monitoring unit is used for acquiring the environment information and transmitting the acquired environment information to the main CPU; and the main CPU is used for switching a monitoring channel when the monitoring unit fails and acquiring the environment information collected by the monitoring device. The system comprises a main control board and at least one service board, wherein a monitoring unit in the main control board is communicated with a monitoring unit in the service board; a main CPU in the main control board is communicated with a main CPU in the service board; a monitoring unit of each service board is used for collecting the environment information of the service board and uploading the collected environment information to the monitoring unit in the main control board; and the monitoring unit in the main control board is used for collecting the environment information of the main control board and transmitting the environment information of the main control board and the environment information of each service board to the main CPU of the main control board. By the device and the system, the usability and the maintainability of an embedded system are greatly enhanced.

Description

technical field [0001] The invention relates to the field of embedded system environment information monitoring, in particular to a single board information monitoring device and a distributed single board information monitoring system. Background technique [0002] At present, embedded systems are becoming more and more complex with powerful functions, and there are more and more chips on a single board. In order to better monitor the environmental information around each device, there are often a large number of temperature sensors and humidity sensors in embedded systems. , Voltage power sensors and other devices. The main CPU can access each monitoring device through the corresponding bus interface, but when the main CPU fails, the environmental information cannot be fed back to the user, and the user has no way to know the environmental information at that time, which is not conducive to equipment maintenance. For this reason, a monitoring unit independent of the main ...
