Abstract

The invention discloses a temperature sensing method, device and system of a hardware-free temperature sensor. The method comprises the following steps: acquiring a PHY chip temperature of a network card interface; pHY chip temperature values at different sampling time points are recorded, the PHY chip temperature values are recorded in a MySQL database, linearization and noise reduction processing is carried out on the PHY chip temperature values, and a PHY chip isothermal curve data model is established; migrating the established PHY chip isothermal curve data model to a CPU temperature curve data model according to the relationship between the CPU temperature and the PHY chip temperature; and linearly comparing the MySQL database, and calculating to obtain CPU temperature values corresponding to different sampling time points. By the adoption of the technical scheme, stability monitoring can be carried out on an old computer system without a CPU temperature sensor, and especially temperature monitoring of a core component CPU can be carried out.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a temperature sensing method, device and system without a hardware temperature sensor. Background technique [0002] Computer systems have been applied to various fields of today's society, especially important fields such as water conservancy, power generation and gas, which are related to the national economy and people's livelihood. It is of great significance to monitor the stability of business systems running in various fields, especially the temperature monitoring of the core component CPU. But since older devices don't have hardware temperature sensors, they can't sense temperature changes. [0003] Therefore, the present invention provides a method for sensing CPU temperature without a hardware temperature sensor. SUMMARY OF THE INVENTION [0004] The present invention provides a temperature sensing method without a hardware temperature sensor, comprising: [0...
