Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a coupler control system, method, terminal and storage medium. Background Art

[0002] In modern communication systems, couplers are key components that ensure effective signal transmission and are indispensable for maintaining the accuracy and continuity of data transmission. However, the current in the communication line is not constant and is easily disturbed by various external factors such as load changes and power supply fluctuations, which in turn cause current fluctuations.

[0003] The traditional technical solution is usually to increase the energy storage power supply, control the charging and discharging of the energy storage power supply to ensure that the coupler can operate stably when the current of the communication line changes, and reduce the impact of current fluctuations. This method has worked to a certain extent, but with the continuous development of communication technology and the increasing requirements for communication quality, its limitations have gradually emerged. On the one hand, the response speed to current changes in the existing technology is slow, and it does not consider dynamically adjusting the charging current and discharging current as the current changes in the circuit. When the current changes rapidly, it may not be possible to adjust its own working state in time to adapt to the current fluctuations. This may cause interruption or distortion of signal transmission, seriously affecting the quality of communication. For example, in the process of real-time communication or data transmission, instantaneous current fluctuations may cause the loss or damage of important information, causing great inconvenience to users. On the other hand, the existing technology cannot accurately control the charging current and discharging current according to the rate of change of the current in terms of energy management, which makes the energy distribution and utilization efficiency in the circuit low, which not only causes energy waste, but also may cause the system to heat up. In addition, under the existing technology, frequent and inappropriate charging and discharging will accelerate the aging of the energy storage power supply, causing its performance to decline, requiring more frequent replacement, increasing maintenance costs and resource consumption, and the aging of the energy storage power supply may also cause its output current to be unstable, further affecting the working performance of the coupler, forming a vicious circle. This is the shortcoming of the existing technology. Summary of the invention
