Problems solved by technology

[0013] However, it is difficult to realize the structure of the RF power control device 100 in the prior art only in the form of hardware and software, and at the same time, many problems will arise during use.
[0014] First. Regarding the setting of the temperature value for operating the above switch
[0015] Second. When operating the above power back mode (power back mode), there will be an overshoot problem
[0016] Third. When cutting off the operation of the above switch, it is necessary to perform two calibration operations according to the opening / closing timing, which is also inconvenient
[0018] However, in the method of cutting off the power supply by means of a temperature sensor, repeaters or base station equipment are mainly used, but it is difficult to use them on high-output mobile communication terminals such as telematics terminals as described above.

Abstract

The invention relates to a RF power control device which monitors the internal temperature of remote message processing terminal computers and of contour output mobile communication terminals and controls power levels on the ''power level 1'' of the AMPS type thus restraining affiliated element fever. The RF power control device of the invention comprises a sensor for monitoring the internal temperature of the contour output mobile communication terminals, an HDET part for sensing the transmission power of the communication terminals and a communication part which transmits the temperature information of temperature sensor and the power numerical values of thte HDET part, controls the power levels and at the same time compares the internal temperature with the set critical temperature so as to adjust the transmission power levels. The invention is free from the influence of overshooting and hardware structure super-addition and can restrain the internal fever of the contour output mobile communication terminals. On vehicles where correcting operation according to control operation is not necessarily conducted, assembling is fit for special conditions. The invention achieves barrier-free communication and controls only the transmission power levels, thus effectively preventing overheating.

Description

technical field [0001] The invention relates to an RF power control device of a high-output mobile communication terminal. Background technique [0002] In the case of a mobile communication terminal that generally uses CDMA (code division multiple access), in the process of performing gain control communication with the base station, if the communication is performed at the maximum power, the function will not be caused by heat generation. abnormal. [0003] However, in a mobile communication terminal that performs communication at a high output, depending on the usage environment, in the case where heat is generated in the chipset environment of the product, the chipset or other components can be guaranteed to operate normally within a limited temperature of 70 degrees to 80 degrees . When the above-mentioned high-output mobile communication terminal is used in summer or in a high-temperature / high-humidity area, it may cause abnormal operation. [0004] That is, the tem...
