Description

Technical Field

[0001] The present invention relates to the technical field of communication technologies, and in particular to a modular energy-saving control system for a communication base station. Background Art

[0002] Communication base station, i.e. public mobile communication base station, is a form of radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication exchange center in a limited radio coverage area. The base station is the basic unit that constitutes a cellular cell in mobile communication, and completes the communication and management functions between the mobile communication network and mobile communication users.

[0003] In order to reduce the energy consumption and carbon emissions of base stations, as well as reduce equipment heating, temperature and equipment noise, communication base stations generally choose to install energy-saving control systems to solve these problems. However, since traditional energy-saving control systems rely too much on manual settings, they cannot achieve intelligent and adaptive energy efficiency management, and may not provide sufficient security monitoring for base stations, and cannot effectively prevent illegal intrusion and electricity theft. Therefore, with the continuous development of energy-saving control technology, they have gradually been eliminated by the market, and the current energy-saving control systems have basically achieved full automatic control.

[0004] For example, the patent document with application number 202410434280.0 discloses an energy-saving control system and method for a communication base station room. The invention controls the air conditioning or ventilation equipment to cool down the room by setting a threshold for the temperature in the room. When the temperature in the room is high, the air conditioning equipment is detected by current through the infrared code in the cloud, and the infrared code of the air conditioning model is automatically matched to realize remote control of the air conditioner or the ventilation fan. When the temperature in the room drops to the requirement, the air conditioner or ventilation fan can be turned off remotely, which can accurately control the opening or closing of the air conditioner or ventilation fan, greatly improving the accurate shutdown rate of the air conditioner or ventilation fan and reducing energy consumption.

[0005] However, the existing energy-saving control systems similar to the above applications still have the following shortcomings:

[0006] Although the existing energy-saving control system is designed with temperature control energy saving, which can reduce the energy consumption of communication base stations in temperature control, the control logic is complex and cumbersome, and it requires a lot of computing resources. It is also impossible to select the temperature control method based on the temperature control rate. At the same time, it also ignores the energy saving of equipment operation, which is not conducive to further reducing energy consumption and operating costs, affecting the energy-saving effect. In addition, due to the lack of modular design, the system cannot be flexibly expanded and combined as needed. When any module fails, it cannot be repaired and maintained independently, which will affect the operation of the entire system.

[0007] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and shortcomings, and provides a communication base station modular energy-saving control system. Summary of the invention

[0057] The present invention provides a communication base station modular energy-saving control system, which has the following beneficial effects:

[0058] The present invention uses modular design to carry out energy-saving control from two directions: temperature control energy saving and operation energy saving, so that the system can adapt to different environmental conditions and operation requirements. For temperature control energy saving, a temperature control instruction generation logic with minimum energy consumption is designed, which can not only determine whether the communication base station needs temperature control with the shortest logical path, but also select a better temperature control method based on the difference calculation result between the temperature control rate of the ventilation fan and the temperature control rate of the air conditioner. Especially for the temperature control of the ventilation fan, it can cooperate with the wind direction outside the base station to realize the windward ventilation fan, further improving the energy saving effect. For operation energy saving, AI is used to predict the changes in network traffic and traffic volume in different time periods and user density, and multi-base station collaboration is performed to dynamically adjust the working status of the base station equipment, so as to more effectively perform energy management according to the actual needs of the base station, reduce energy consumption and operating costs, and achieve more efficient energy saving effects.

A communication base station modular energy-saving control system according to claim 1, characterized in that: The main control module uses a single-chip microcomputer or a microprocessor as the main control unit, and the operating logic of the single-chip microcomputer is as follows: Power-on reset: When the power is turned on, a power-on reset operation is performed to reset the internal state of the microcontroller to the initial state; PC initialization: PC points to the starting address of the program memory and is ready to start executing the program; Instruction fetch: The microcontroller fetches instructions from the program memory according to the address in the PC, and automatically adds 1 to the value of the PC to fetch the next instruction; Instruction decoding: The instruction decoder inside the MCU decodes the fetched instruction, determines the instruction's operation code and operand, and prepares to execute the corresponding operation; Instruction execution: According to the decoding results, the microcontroller performs the corresponding operation. When it comes to reading and writing data, it exchanges data with the internal memory and external devices through the data bus; Repeated execution: After executing an instruction, the microcontroller returns to the instruction fetch stage and continues to execute the next instruction until the program ends or an interrupt request is encountered; The operating logic of the microprocessor is as follows: Initialization: When the power is turned on, a power-on reset operation is performed to reset the internal state of the microprocessor to the initial state; Instruction prefetching: While executing the current instruction, the microprocessor pre-fetches the next instruction from the instruction cache or memory; Instruction fetch, decode and execute: The microprocessor fetches instructions from the instruction cache or memory, decodes them and executes the corresponding operations; Pipeline processing: Pipeline technology is used to divide the execution process of instructions into several stages, so that each stage can process different parts of different instructions in parallel; Interrupt processing: During the execution of instructions, if the microprocessor encounters an interrupt request, it will suspend the execution of the current instruction and switch to processing the interrupt service program. After processing the interrupt, it will restore the execution state before the interruption and continue to execute the original program.
