Description

Technical Field

[0001] The present invention relates to the technical field of safe power supply control for communication base stations, and in particular to a method and system for safe control of photovoltaic power supply for communication base stations based on a cloud control platform. Background Art

[0002] A communication base station is an access device that enables multiple user terminals to communicate with the access network or other networks. Its primary function is similar to that of an OLT, but unlike an OLT, a communication base station is a wireless access point. User terminals typically do not have IP addresses, only MAC addresses. The base station requires an IP address from the carrier and uses the carrier's bandwidth resources. Communication base stations are typically powered by mains electricity, batteries, or photovoltaic power. Mains electricity requires laying transmission lines, while batteries have limited energy storage and cannot be replenished in a timely manner. Therefore, photovoltaic power is a more environmentally friendly and economical solution.

[0003] When photovoltaic power supply is used, the photovoltaic components are prone to the following situations: (1) short circuit failure, resulting in power reduction or disappearance, affecting the power compensation of the communication base station; (2) open circuit failure, resulting in power reduction, affecting the power compensation of the communication base station; (3) excessive temperature, affecting the power compensation of the communication base station; (4) component power attenuation, affecting the power compensation of the communication base station; (5) component shadow, affecting the power compensation of the communication base station. When the photovoltaic components have the above failures, it will not be able to provide continuous power. At this time, it is necessary to switch the photovoltaic power supply to battery power supply in time. However, the battery power supply has limited stored energy. The existing battery is set to three groups, namely one main battery and two backup batteries. Although it can meet the normal power supply for a period of time, the power consumption is fast, which wastes energy and has a limited service life. It requires manual maintenance and replacement in a timely manner. Summary of the Invention

[0023] As a further limitation of the first aspect of the present invention, a judgment threshold for the battery to release electrical energy is determined based on the initial value and actual value of the battery power.

[0042] To facilitate understanding of the present invention, the present invention is further explained below with reference to specific embodiments in conjunction with the accompanying drawings, and the specific embodiments do not constitute a limitation to the embodiments of the present invention.

[0043] Those skilled in the art should understand that the drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily necessary for implementing the present invention. Example 1

[0044] This implementation proposes a photovoltaic power supply safety control method for communication base stations based on a cloud control platform, which includes the following steps:

[0045] S1: Status monitoring: obtaining the operating status information of the photovoltaic modules powered by the communication base station in real time, and comparing the operating status information with a preset operating status threshold;

[0046] S2: Abnormality determination: If the operating status information exceeds a preset operating status threshold, it is determined that the component is operating abnormally, and the power supply mode of the communication base station is controlled to switch from power supply by the photovoltaic component to power supply by the battery;

[0047] S3: Power supply mode switching: controlling the photovoltaic module to stop external discharge, starting the photovoltaic module, collecting excess electrical energy generated by the photovoltaic module, and storing it in a battery;

[0048] S4: Energy storage monitoring: obtaining the battery power information in real time, and when the battery reaches the release mode, obtaining the current light intensity of the photovoltaic module, and determining whether the light intensity is within a preset light intensity range;

[0049] S5: Release adjustment: If the light intensity is within a preset light intensity range, control the battery to stop supplying power to the base station; otherwise, determine a release ratio corresponding to the light intensity, and control the battery output power according to the release ratio.

[0050] In this implementation, the photovoltaic components and the batteries are both connected to the base station, and the terminal voltage V1 of A1 and A2 and the terminal current I1 of A1 and A2 of the photovoltaic components that power the base station are obtained in real time. The terminal voltage and terminal current are compared with the preset voltage threshold and current threshold respectively. The voltage threshold and current threshold here are the preset operating status thresholds.

[0051] Specifically, when the terminal voltage V1 is greater than a preset voltage threshold, or when the terminal current I1 is greater than a preset current threshold, the photovoltaic module is determined to be operating abnormally. The power supply mode is switched, the photovoltaic module stops discharging externally, and the photovoltaic module is started to collect the electrical energy generated by the photovoltaic module and store it in the battery. When the terminal voltage V1 is less than or equal to the preset voltage threshold, and the terminal current I1 is less than or equal to the preset current threshold, the photovoltaic module is determined to be operating normally.

[0052] The battery is connected to the photovoltaic assembly, and the battery supplies power to the gateway;

[0053] The battery includes a supercapacitor and an AC / DC converter, wherein the supercapacitor and the AC / DC converter are connected in series. The supercapacitor is connected to the battery, the AC / DC converter is connected to the battery, the battery is connected to the communication base station, and the AC / DC converter is simultaneously connected to the battery, the gateway, and the battery.

[0054] Specifically, the battery supplies power to the gateway. When the photovoltaic module operates abnormally, the battery is controlled to supply power to the communication base station to ensure normal communication use of the communication base station. The battery is connected to the photovoltaic module, and the photovoltaic module charges the battery to ensure the power of the battery.

[0055] The battery is connected to the AC / DC converter to convert the battery voltage to the voltage required by the AC / DC converter, ensuring the normal operation of the AC / DC converter. The battery is connected to the AC / DC converter to store the output power of the AC / DC converter in the battery. The battery is connected to the gateway and, when the battery voltage is insufficient, it powers the gateway to ensure its operation.

[0056] The battery is connected to the photovoltaic module and stores the electrical energy generated by the photovoltaic module in the battery. If the battery charge exceeds a preset charge threshold, the battery is controlled to stop supplying power to the gateway. If the battery charge is equal to the preset charge threshold, the battery is directly controlled to supply power to the gateway. If the battery charge is less than the preset charge threshold, the light intensity A of the photovoltaic module is determined, a preset light intensity range B is obtained, and the battery is controlled to supply power to the gateway.

[0057] Specifically, if the battery power is less than a preset power threshold, the photovoltaic module stores electrical energy in the battery. If the battery power reaches the preset power threshold, the battery is controlled to stop supplying power to the gateway. If the battery power is less than the preset power threshold, it is determined whether the light intensity of the photovoltaic module is less than a preset light intensity range.

[0058] If the light intensity of the photovoltaic component is less than the preset light intensity range B, the battery still supplies power to the gateway; if the light intensity is greater than or equal to the preset light intensity range B, the release ratio corresponding to the light intensity is determined, and the battery output power is controlled according to the release ratio.

[0059] In one embodiment, when the light intensity is less than the preset light intensity range, if the light intensity is less than the preset maximum light value, the corresponding release ratio B1 is determined, and the battery releases electrical energy according to the release ratio B1; if the light intensity is less than the preset minimum light value, the corresponding release ratio B2 is determined, and the battery releases electrical energy according to the release ratio B2.

[0060] In one embodiment, if the illumination intensity of the photovoltaic assembly is greater than the preset threshold range, the battery is controlled to stop supplying power to the gateway.

[0061] If both V1 and I1 of the photovoltaic module are greater than the preset voltage and current thresholds of the photovoltaic module, the power supply mode is switched, the photovoltaic module stops discharging electricity, and starts to operate, collecting the electricity generated by the photovoltaic module and storing it in the battery. When V1 is less than the preset voltage threshold and I1 is less than the preset current threshold, the photovoltaic module operates normally and stops collecting the electricity generated by the photovoltaic module.

[0062] The battery is connected to the AC / DC converter and vice versa. The AC / DC converter converts the voltage generated by the battery into a supply voltage and stores it in the battery. When V1 is less than a preset voltage threshold and I1 is less than a preset current threshold, the battery is controlled to power the gateway. The voltage generated by the battery is converted into a supply voltage to ensure the normal operation of the gateway.

[0063] The battery is connected to both the photovoltaic module and the AC / DC converter. Terminal A2 of the photovoltaic module is connected to terminal A3 of the battery, which is connected to the AC / DC converter. Terminal A3 and the AC / DC converter are both connected to the battery. Excess electricity from the photovoltaic module is stored in the battery. When the battery's charge reaches a threshold, the battery is directly controlled to power the gateway. When the gateway consumes too much power and the battery's power supply cannot meet the gateway's operating requirements, the battery will power the gateway.

[0064] The gateway is connected to the battery, the AC / DC converter, and the battery. The AC / DC converter is connected to the battery and converts the voltage of the photovoltaic panel or the battery into a power supply voltage to ensure normal operating voltage for the gateway. If the battery charge level is greater than a preset charge threshold, the AC / DC converter draws power from the battery. If the battery charge level is equal to the preset charge threshold, the AC / DC converter directly powers the gateway.

[0065] Obtain the power level of the battery, determine whether the current power level of the battery is less than a preset power threshold, and if so, determine the light intensity of the photovoltaic component. When the light intensity is greater than a preset light intensity range, stop supplying power to the gateway. If the light intensity is less than or equal to the preset light intensity range, determine a release ratio corresponding to the light intensity, and provide the gateway with the currently required power according to the release ratio.

[0066] When the power level of the battery is greater than a preset power threshold, the battery stops supplying power to the gateway.

[0067] When V1 is greater than a preset voltage threshold, or I1 is greater than a preset current threshold, the photovoltaic component is judged to be operating abnormally. According to the status monitoring result, the power supply mode is controlled to switch, and the photovoltaic component stops discharging to the outside; the photovoltaic component is started, and the excess electric energy generated by the photovoltaic component is collected and stored in the battery.

[0068] The communication base station includes Vnet. When V1 is greater than a preset voltage threshold, or I1 is greater than a preset current threshold, Vnet obtains V1 and I1 information; determines whether the V1 and I1 information are abnormal; if the V1 or I1 information is abnormal, controls the power supply mode to switch, and controls the battery to power the power supply base station. If the battery power threshold is greater than a preset power threshold, controls the battery to stop powering the gateway.

[0069] If the battery power is less than or equal to a preset power threshold, obtain the light intensity A of the solar panel and determine whether A is less than a preset light intensity range B; if the light intensity A is less than the light intensity range B, determine the corresponding release ratio B1 or B2 according to the light intensity A, and use the battery to power the gateway according to the preset ratio B1 or B2; if A is equal to B, it is determined to be a normal working state, and the energy storage module is controlled to normally power the gateway; if A1 is greater than the A1 threshold or I1 is greater than the I1 threshold, control the power supply mode to switch, and stop the photovoltaic panel from discharging externally.
