However, in practical applications, not all systems may be used at the same time, so some channels are often in an empty state, which wastes power and generates a lot of heat at the same time, which increases the temperature inside the module and has a negative impact on the module.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] refer to figure 1 The present invention provides a device for controlling a power amplifier according to downlink power, which is applied to an optical fiber distribution system. The device comprises a main control unit 10 and a first inquiry unit 11 connected to the main control unit 10, a first judging unit 12, a second judging unit 13, a control unit 14, a comparison unit 15, a second inquiring unit 16, and a third judging unit. unit 17 , polling unit 18 , saving unit 19 , first checking unit 20 , and second checking unit 21 .

[0033] The first inquiry unit 11 is used to inquire about the power of all systems corresponding to the remote power amplifier on the digital board and predict the signal power to be output by each system on the corresponding power amplifier channel.

[0034] The first judging unit 12 is configured to compare the out...

Abstract

The invention relates to a method and device for controlling a power amplifier according to downlink power. The method comprises the following steps of searching all systems of power on a digital plate and predicting to-be-output signal power of each system on a corresponding power amplifier channel, wherein the power corresponds to a far end power amplifier; comparing the to-be-output signal power of each system with a preset threshold value, and if the to-be-output signal power is smaller than the preset threshold value, judging that the system corresponding to the signal power is not used; judging use condition of all systems, if all systems are not used, closing the power amplifiers, if any system of all systems is used, opening the power amplifier; and comparing the closed or opened state of the power amplifier with a current state of the power amplifier, if the states are different, closing or opening the power amplifier and recording the state of the power amplifier, and if the states are the same, not carrying out processing. According to the method and the device, the power amplifier is opened when the power amplifier needs to be used and is closed when the power amplifier does not need to be used and the power amplifier channels are prevented from empty load.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of wireless communication, in particular to a method and device for controlling a power amplifier according to downlink power. [0003] 【Background technique】 [0004] In an optical fiber distribution system, several systems are generally integrated, and in some highly integrated projects, more than a dozen systems are required to be integrated at the same time. The systems with different frequencies will occupy different channels on the power amplifier. However, in practical applications, not all systems may be used at the same time, so some channels are often in an unloaded state, which wastes power and generates a lot of heat, which increases the temperature inside the module and has a negative impact on the module. If the power amplifier channel can be opened only when the power amplifier is needed, and the power amplifier channel is automatically closed when the power amplifier is not in...
