Device heating method

Abstract

The invention discloses a device heating method. A marking device is heated to a target temperature by a plurality of temperature ranges. The method comprises the following steps of: sensing the current device temperature of the marking device; comparing the current device temperature with range set temperature in a current temperature rang to obtain a stage error value; regulating heating power according to the stage error value; heating the marking device with the heating power; progressively rising the range set temperature in the current temperature range by using a preset temperature progressive rising value to obtain the range set temperature of the next temperature range; and repeating the same steps in each temperature range until the range set temperature or device temperature reaches the target temperature.

Description

【Technical field】 [0001] The present invention relates to the design of a heating method, in particular to a device heating method. 【Background technique】 [0002] If an electronic device (such as a notebook computer) needs to start or operate in a low temperature environment, a heater (such as a hard disk heater) is required to heat a specific hardware module (such as a hard disk). However, the current heaters, whether they are controlled by hardware circuits or application software or firmware, are simply heated with a fixed heating power, or heated at different temperatures with different heating powers. [0003] refer to figure 1 As shown, the temperature curve W1 represents the relationship between the temperature and time of the heated device when the existing heating technology is used for heating. The existing heating technology only considers the target temperature Tf to be heated to by the device, and does not consider the temperature change at each time point du...

Problems solved by technology

[0007] When the initial temperature Td0' of the device is different, because the existing heating technology uses ordinary heating power to heat, the temperature curve W3 shows that it has already been heated to the target temperature Tf before the predetermined heating time course F1, resulting in an instantaneous overheating situation

[0008] In view of the above, when using the existing heating technology to heat a certain device, there will be problems such as uneven temperature rise rate, excessive instantaneous temperature change and uncontrollable heating time.

For devices with heat-sensitive characteristics, the heating mechanism cannot be adjusted by itself

In addition, once the heater changes the heating source, the characteristic resistance of the heating medium changes, or uses a heater to heat different devices, the temperature curve will also change greatly, and the heating effect cannot be predicted and controlled.
