Sensor information transmission system, method and device and storage medium

Abstract

The invention discloses a sensor information transmission system, which is applied to a BMC (baseboard management controller), and comprises: a plurality of sensor information subscription modules, wherein each sensor information subscription module is used for subscribing a theme of sensor information required by the sensor information subscription module in advance; a sensor information issuingmodule which is used for reading the information of each sensor, and sending the information of the sensor to the intermediate module when determining that the information of any sensor is changed; and an intermediate module which is used for obtaining the theme of the sensor information after receiving any one of the sensor information sent by the sensor information publishing module, and sendingthe sensor information to each sensor information subscription module which subscribes the theme of the sensor information. By applying the scheme provided by the invention, the sensor information can be conveniently and effectively transmitted, and the occupation of CPU resources is reduced. The invention further discloses a sensor information transmission method and device and a storage mediumwhich have corresponding technical effects.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a sensor information transmission system, method, device and storage medium. Background technique [0002] With the development of information technology, servers have been widely and deeply applied in cloud computing, big data and traditional industries. BMC (Baseboard Management Controller, Baseboard Management Controller) , It plays an important role in providing management interfaces for upper-layer applications. [0003] One of the core interfaces of the BMC is IPMI (Intelligent Platform Management Interface, Intelligent Platform Management Interface). Users can monitor the server through IPMI commands. Sensor monitoring is a core function of the IPMI interface. Through sensor monitoring of parameters such as voltage, temperature, and fan speed, abnormal server operations can be detected in time. [0004] In the existing solution, the hardware access program of the senso...

Problems solved by technology

However, since there are many processes that need to use sensor information in the BMC, mutually exclusive access is required, that is, the hardware access program cannot be accessed by multiple processes that need to use sensor information at the same time, so it is not conducive to the timely delivery of sensor information, thereby affecting stable operation of the system

In addition, processes that need to use sensor information usually periodically query the hardware access program of the sensor, which also consumes a lot of CPU resources.
