Embodiment 1

[0077] Such as figure 1 As shown, the patent of the present invention includes five modules on the physical model:

[0078] The CPU module includes the main CPU, memory and storage unit, which is the main power consumption and heat generation module; the temperature detection module includes a set of temperature sensors, which can convert the temperature near the CPU into digital quantities, and the CPU module and MCU module can pass I2C The bus is used to obtain temperature information; the data selector is used to select whether the I2C bus connected to the temperature sensor is the I2C bus of the CPU or the I2C bus of the MCU. The MCU module is composed of a low-power single-chip microcomputer, which is used to control the channel selection of the data selector, receive the CPU heartbeat signal and data, and communicate with the fan control module through the I2C bus; the fan control module includes the fan control unit and the fan, and receives the MCU module control inst...

Embodiment 2

[0085] Under normal circumstances, the MCU module controls the data selector through the SEL signal, and selects the I2C0 of the CPU module to access the temperature sensor and obtain temperature parameters. The CPU module sends the parameters for controlling the fan to the MCU module through the I2C1 bus, and the MCU module controls the fan through the fan control module on the I2C2 bus according to the acquired parameters.

[0086] When the CPU module cannot work normally due to high temperature or is invaded by viruses, the heartbeat signal of the CPU module will be abnormal. The MCU module will regularly detect the heartbeat signal of the CPU module. When it detects that the heartbeat signal of the CPU module is abnormal, it will control the data selector through the SEL signal, select the I2C0 of the MCU module to access the temperature sensor, and cut off the connection with the I2C1 of the CPU module. The temperature of the temperature sensor controls the fan independen...

Abstract

The present invention provides a fan control method of system and system and a compute readable storage medium. The method comprises 1 periodically transmitting a heartbeat signal of a CPU module to an MCU module at a preset time interval; 2 according to the received heartbeat signal of the CPU module, using the MCU module to judge whether the heartbeat signal of the CPU module conforms to the preset standard, if so, using the MCU module to judge that the heartbeat signal is normal, entering the step 3 and continuing to execute, otherwise, using the MCU module to judge that the heartbeat signal is abnormal, and entering the step 4 and continuing to execute; 3 using the MCU module to read the temperature information of the temperature sensor and controlling the operation of the fan. When the MCU module of the invention detects the abnormal heartbeat signal of the CPU module, the MCU module can perform temperature collection and fan control independently of the CPU module, so as to avoidthe CPU module from being burned due to excessive temperature.

Description

technical field [0001] The patent of the present invention relates to the technical field of system fan control, in particular, to a system fan control method, system, and computer-readable storage medium, and in particular, to a safe system fan control method. Background technique [0002] Due to the rapid development of the scientific and technological communication industry, the application of information products has also become popular, especially the electronic communication equipment with high power consumption, which also frequently appears in daily life. The CPU module of many electronic communication devices is equipped with a fan, and the fan controller controls the fan to send air to the CPU to help the CPU dissipate heat, so that the CPU can run normally and process data quickly, especially in high temperature environments or when the CPU is often at full load work situation. [0003] For electronic communication equipment, display, storage, and CPU are the thr...
