Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 exemplarily shows a system architecture to which the heating method of the remote radio unit according to the embodiment of the present invention is applied, where the system architecture may include a power supply module 101, a digital signal processing module 102, a power amplifier module 103, a monitoring module 104, and a temperature sensor 105. The power module 101 is used for converting 220V mains supply into power supply voltage required by electronic components contained in each module; the digital signal processing module 102 performs up-conversion, digital-to-analog conversion and filtering on the baseband signal to convert the baseband signal into a radio frequency small signal; the power amplifier module 103 is an amplifying circuit for outputting a high-power signal; the monitoring module 104 mainly implements a main control function of the device; the temperature sensor 105 is used to detect the device temperature of the remote radio unit device.
Based on the above description, fig. 2 exemplarily shows a flow of a heating method of a remote radio unit according to an embodiment of the present invention, where the flow may be executed by a monitoring module, and the apparatus may be located in the monitoring module, and may be the monitoring module. As shown in fig. 2, the process specifically includes:
Here, the current device temperature of the remote radio unit is the ambient temperature before the remote radio unit is normally started.
The remote radio unit converts the baseband optical signal into a radio frequency signal at a remote end, amplifies the radio frequency signal and transmits the radio frequency signal, and the remote radio unit can comprise a power supply module, a digital signal processing module, a power amplifier module, a monitoring module and a temperature sensor. The normal starting temperature of the remote radio unit is influenced by the normal starting temperatures of the power supply module, the digital signal processing module, the power amplifier module, the monitoring module and the temperature sensor. The components with a wide working temperature range can be selected as the components of the power supply module, the power amplifier module, the monitoring module and the temperature sensor, so that the normal starting temperature of the power supply module, the power amplifier module, the monitoring module and the temperature sensor is lower than the normal starting temperature of the digital signal processing module.
When the current equipment temperature of the radio remote unit is lower than the normal starting temperature of the radio remote unit, that is, the radio remote unit cannot be normally started at the current equipment temperature, the power amplifier module is started in advance to heat the radio remote unit. Specifically, when the current device temperature of the remote radio unit is lower than the normal start temperature of the remote radio unit, the power amplifier module is turned on in advance, and the heat generated by the power amplifier module during operation is used for heating the digital signal processing module.
And when the temperature of the equipment heated by the remote radio unit is determined to be not less than the normal starting temperature of the remote radio unit, closing the power amplifier module and normally starting the remote radio unit. Equivalently, after the radio remote unit is heated by heat generated by the power amplifier module during working, the normal starting temperature of the radio remote unit can be reached, the heating of the radio remote unit by the power amplifier module can be finished, and then the radio remote unit is normally started.
Here, the normal start temperature of the remote radio unit may be understood as the normal start temperature of the digital signal processing module, and the normal start of the remote radio unit may be understood as the normal start of the power supply module, the digital signal processing module, the power amplifier module, the monitoring module, and the temperature sensor of the remote radio unit. The above embodiment may be understood as turning off the power amplifier module when it is determined that the temperature of the device heated by the remote radio unit is not less than the normal start temperature of the digital signal processing module; and normally starting the power supply module, the digital signal processing module, the power amplifier module, the monitoring module and the temperature sensor.
In order to better explain the embodiment of the present invention, the flow of the heating method of the remote radio unit will be described in the following specific implementation scenarios. It is assumed that the normal start temperature of the power module, the power amplifier module, the monitoring module and the temperature sensor of the remote radio unit is a minimum, and the normal start temperature of the remote radio unit (the normal start temperature of the digital signal processing module) is B minimum, where the temperature B is higher than the temperature a. The flow of the heating method of the remote radio unit is shown in fig. 3.
When the current equipment temperature is not lower than A, the power supply module, the power amplifier module, the monitoring module and the temperature sensor can be started normally, and at the moment, the radio remote unit can be started in a cold mode at a low temperature.
In step 302, a temperature sensor detects a current device temperature.
Step 304, turn on the power amplifier module.
In step 305, the temperature sensor detects the current device temperature.
And step 306, judging whether the temperature is not lower than B. If so, go to step 307, otherwise, go to step 305.
Since the specific implementation of this embodiment has been described in other embodiments, it is not described herein.
In the above embodiment, the current device temperature of the remote radio unit is obtained, and if the current device temperature is lower than the normal start temperature of the remote radio unit, that is, the remote radio unit cannot be normally started at the current device temperature, the power amplifier module is turned on in advance, and the power amplifier module heats the remote radio unit, so that the temperature of the remote radio unit can reach the normal start temperature. Under the premise of ensuring the normal starting of the remote radio unit in a low-temperature environment, the scheme has the following beneficial effects:
1. the method provided by the invention only needs to select parts of components with wider working temperature range to ensure the normal work of the power supply module, the power amplifier module, the monitoring module and the temperature sensor, thereby reducing the production cost of the radio remote unit.
