Device and method for realizing overheating prompt of mobile terminal

Abstract

The invention discloses a device for realizing overheating prompt of a mobile terminal. The device comprises a thermal-sensitive device for acquiring the temperature of a heat emitting device, a baseband processor and an alarm device, wherein the baseband processor obtains the temperature rising speed of the heat emitting device according to the temperature acquired by the thermal-sensitive device, compares the temperature rising speed with the pre-stored conventional temperature rising curve of the heat emitting device, and sends an alarm command to the alarm device when the temperature rising speed of the heat emitting device is higher than the temperature rising speed corresponding to the conventional temperature rising curve and the power of transmitting a signal is over a preset threshold value; and the alarm device generates an alarm according to the alarm command. The invention also discloses a method for realizing overheating prompt of the mobile terminal. The scheme of the invention can prompt the user and inform the user the current communication condition and the heating state when the communication environment becomes bad and the temperature rising speed of the mobile terminal becomes faster.

Description

technical field [0001] The invention relates to a mobile terminal overheat detection technology, in particular to a device and method for realizing a mobile terminal overheat prompt. Background technique [0002] In today's highly developed wireless communication system, people have become accustomed to maintaining voice communication with relatives and friends and accessing network resources anytime, anywhere through convenient and light mobile terminals. With the development of chip packaging technology, more and more functions are being integrated into small mobile terminals, and this type of products has shown a corresponding trend of substantial increase. However, customer demand and competitive pressure force mobile terminal manufacturers to pursue miniaturization. This development trend of mobile terminal design has led to an increase in the heat generation density per unit volume in the mobile terminal, and in the limited space inside the mobile terminal, it is impos...

Problems solved by technology

It is noteworthy that when the radio frequency signal is transmitted at high power, the power amplifier is usually working at full capacity, and the power amplifier generates the most heat in the mobile terminal, causing a large amount of heat to be generated, and the temperature of the mobile terminal rises extremely fast, so that the user can obviously Feel the hotness of the mobile terminal, which is the worst user experience mentioned above

[0006] In addition, in the existing mobile terminals, it is common only to display the signal bar on the corner of the screen according to the received power read by the radio frequency chip of the mobile terminal, and use the grid number to represent the strength of the signal; In the case of not using the headset to make a call, it is impossible to know the quality of the local signal during the mobile call, and it is even more impossible to know the working status of the power amplifier, whether the mobile terminal has overheated or is about to overheat, etc.

[0007] Moreover, the existing mobile terminals do not prompt the user that the heating of the mobile terminal is caused by the bad communication environment where the user is located; nor do they find that the temperature rises too fast according to the temperature detection and signal detection, and remind the user that the current environment where the wireless communication Poor signal quality, long-term calls will cause overheating of the mobile terminal, or suggest that users try to change the communication location to improve the heating of the mobile terminal
