It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
At present, monitoring equipment of a power transmission line and a transformer substation is required to be provided with a set of independent and complete power supply system, so that the construction difficulty is high, the maintenance cost is high, the fault probability is high, the use of high-quality and high-power devices is limited, the problems of repeated resource construction and excessive occupation of tower body resources of a tower are also existed, the installation cost is increased when the monitoring equipment is installed, and the stability of each power supply system is not easy to guarantee, so that the normal operation of the monitoring equipment is easily influenced due to faults; meanwhile, the monitoring equipment on the power transmission line usually adopts a solar power supply mode, and under the condition of insufficient electric quantity, the power supply of each monitoring equipment cannot be managed in a unified mode.
The embodiment of the invention discloses a power supply control method of power transmission line monitoring equipment.

step S103, acquiring the current residual electric quantity of the solar battery for supplying power to each monitoring device;
in the embodiment, the solar cell is powered by a photovoltaic panel and adopts a 600 to 800Ah @12V colloid battery;
and step S104, determining the current power supply priority according to the current residual power based on a second preset mapping table, and supplying power to the monitoring equipment with the corresponding power supply priority according to the current power supply priority, wherein the second preset mapping table comprises a corresponding relation between a plurality of groups of residual power intervals and the power supply priority.
And acquiring the electricity utilization data of each monitoring device and the current residual electricity quantity of the solar battery through the current collector and the voltage collector.
In the above embodiment, in the process that the power supply supplies power to the monitoring devices, the power consumption data of each monitoring device is detected, the power consumption of each monitoring device within the preset power consumption duration is obtained according to the power consumption data, and meanwhile, the residual power of the solar cell, that is, the current residual power, is detected in real time; dividing each monitoring device into a plurality of power supply priorities according to the power consumption of each monitoring device within the preset power consumption duration based on a first preset mapping table; based on the second preset mapping table, the current power supply priority is determined according to the current residual capacity of the solar battery, so that when the residual capacity of the solar battery is insufficient, power is preferentially supplied to part of monitoring devices, and the unified management of power supplies of a plurality of monitoring devices is realized.
For example, monitoring equipment with the electricity consumption less than 0.1 kilowatt hour in the preset electricity consumption duration may be used as a first power supply priority, monitoring equipment with the electricity consumption more than or equal to 0.1 kilowatt hour and less than 0.5 kilowatt hour in the preset electricity consumption duration may be used as a second power supply priority, and monitoring equipment with the electricity consumption more than or equal to 0.5 kilowatt hour in the preset electricity consumption duration may be used as a third power supply priority; the priority of the monitoring equipment from the first power supply priority to the monitoring equipment from the third power supply priority is decreased; for example, when the remaining capacity of the solar cell is greater than or equal to thirty percent of the total capacity of the solar cell, the solar cell simultaneously supplies power to all the monitoring devices within the first power supply priority, the second power supply priority and the third power supply priority; when the residual electric quantity of the solar cell is more than or equal to twenty percent of the total capacity of the solar cell and less than thirty percent of the total capacity of the solar cell, the solar cell simultaneously supplies power to all monitoring equipment in the first power supply priority and the second power supply priority; and when the residual capacity of the solar battery is less than twenty percent of the total capacity of the solar battery, only the monitoring equipment in the first power supply priority level is powered.
As an implementation manner of power consumption calculation, the specific step of calculating the power consumption of each monitoring device according to the power consumption data includes that the power consumption is obtained according to the power consumption voltage, the power consumption current and the preset power consumption duration: electricity consumption = electricity voltage and electricity current and preset electricity consumption duration; the preset power-on time can be determined according to actual conditions, for example, the preset power-on duration can be set to be 24 hours, namely, the power consumption of each monitoring device in one day is calculated;
referring to fig. 1, as a further embodiment of the power supply control method, after the step of generating the power supply priority of each monitoring device, the method further includes:
sending a first preset mapping table to a management terminal; the management terminal is used for adjusting the first preset mapping table and monitoring equipment in each power supply priority, and the adjustment of the first preset mapping table comprises adjustment of an interval range of a power consumption interval;
the management terminal may be a computer terminal in a monitoring room, or may be an intelligent mobile terminal of a manager, such as a mobile phone, a tablet, and the like.
In the above embodiment, the management terminal receives the first preset mapping table, and the manager adjusts the interval range of the power consumption interval of the first preset mapping table through the management terminal according to the actual situation, where the adjustment at least includes adjustment of the interval of the power consumption interval and adjustment of the endpoint of the power consumption interval, so as to facilitate more reasonable power supply priority division according to power consumption adjustment of each monitoring device; meanwhile, the management terminal is also used for adjusting the power supply priority of each monitoring device, and a manager can freely adjust the power supply priority of the monitoring device according to the importance degree of the monitoring device;
for example, important equipment which has a higher power consumption in a preset power consumption duration and is used as a monitoring key point can be adjusted to a first power supply priority so as to preferentially ensure the power supply of the important equipment; or the monitoring equipment which has lower power consumption within the preset power consumption duration and is not taken as a monitoring key point is adjusted to a third priority level, so that the power consumption is reduced and the energy is saved under the condition of insufficient power supply of the solar battery; the effect of preferentially ensuring the power supply of important monitoring equipment when the electric quantity of the solar cell is insufficient is achieved.
Referring to fig. 2, as a further embodiment of the control method, it is determined whether the current remaining power is lower than a preset power warning value, if so, a power warning signal is generated, and the power warning signal is sent to a management terminal; the management terminal is used for receiving the electric quantity early warning signal and controlling each monitoring device to reduce the monitoring frequency;
in the embodiment, when the electric quantity of the solar battery is lower than the preset electric quantity early warning value, the electric quantity early warning signal is sent to the management terminal, and a manager can easily and timely obtain a signal that the electric quantity of the solar battery is insufficient through the management terminal so as to complete subsequent related work, and meanwhile, the manager can adjust the monitoring frequency of each monitoring device according to actual conditions;
for example, the time interval for reporting the monitoring data by the microclimate sensor and the icing tension sensor is once in 10 minutes, when a manager receives an electric quantity early warning signal, the time interval for reporting the monitoring data by the microclimate sensor and the icing tension sensor can be remotely adjusted to once in half an hour through the management terminal, so that the power consumption of part of monitoring equipment is reduced, and the service life of the residual electric quantity of the solar cell is prolonged; and when the residual electric quantity of the solar battery is greater than or equal to the preset electric quantity early warning value, canceling the warning of the electric quantity early warning signal.
In addition, the preset electric quantity early warning value can be determined according to actual conditions and historical experience, but when the residual electric quantity of the preset electric quantity early warning value is higher than the highest residual electric quantity of the power supply priority, for example, the preset electric quantity early warning value can be set to be forty percent of the residual electric quantity of the solar battery, the power supply priority can perform partial power supply when the residual electric quantity is lower than thirty percent, namely, an electric quantity early warning signal is sent to the management terminal, and the residual electric quantity is not supplemented, namely, the residual electric quantity is supplied to a part of monitoring equipment according to the priority of the power supply priority.
Referring to fig. 3, as a further embodiment of the power supply control method, after the step of generating the electric quantity early warning signal, the method further includes:
acquiring illumination intensity data in a preset time period;
and judging whether the illumination intensity data is lower than a preset illumination intensity threshold value, if so, sending a charging prompt signal to the management terminal.
The method for acquiring the illumination intensity data can be to call the illumination intensity data of the meteorological platform or integrate the illumination intensity data of the meteorological platform through monitoring data of related equipment such as a microclimate sensor in monitoring equipment; the preset time is a period of time after the electric quantity early warning signal is generated, for example, the illumination intensity data within one hour after the electric quantity early warning signal is generated can be obtained.
In the above embodiment, after the electric quantity of the solar battery is lower than the preset electric quantity early warning value, the illumination intensity data in the preset time period is acquired, and if the illumination intensity data is lower than the preset illumination intensity threshold value, it is indicated that the illumination used by the solar battery for charging in the current time period is insufficient, and at this time, the remaining electric quantity of the solar battery is low and may be caused by insufficient illumination, and a charging prompt signal is sent to the management terminal, so that a manager can perform manual charging according to actual conditions. It is noted that the illumination intensity data should be collected as an average illumination intensity over a period of time, rather than illumination intensity data at one point in time.
As a further scheme of sending the charging prompt signal, after the step of acquiring the light intensity data within the preset time period,
acquiring current time information, and judging whether the current time is in the day or at night according to the current time information;
wherein, the time from the local sunrise time to the local sunset time is the day, and the time from the local sunset time to the local sunrise time is the night;
if the current time is in the daytime, judging whether the illumination intensity data is lower than a preset illumination intensity threshold value, and if so, sending a charging prompt signal;
and if the current time is at night, acquiring weather forecast information after sunrise, judging whether enough illumination intensity is available for charging the solar battery after sunrise or not according to the weather forecast information after sunrise, if so, not sending a charging prompt signal, and if not, sending the charging prompt signal.
And if the weather forecast information after sunrise is sunny, judging that enough illumination intensity exists after sunrise, and if the weather forecast information after sunrise is cloudy or rainy, judging that enough illumination intensity does not exist after sunrise.
In the above embodiment, if the current time is daytime, but an electric quantity early warning signal is generated and the illumination intensity data in the preset time period is lower than the illumination intensity threshold, it indicates that the insufficient electric quantity of the solar cell is insufficient due to insufficient illumination intensity caused by factors such as weather; if the current time is night, the obtained illumination intensity is lower than an illumination intensity threshold value, then the judgment of the weather forecast after sunrise is carried out, if enough illumination intensity is predicted to charge the solar battery after sunrise, a charging prompt signal is not sent first, and if not enough illumination intensity is predicted to charge the solar battery after sunrise, a charging prompt signal is sent; the solar battery cannot be charged at night, namely the solar battery is in a discharging process at night, the situation that the electric quantity of the solar battery is lower than an electric quantity early warning value can be caused at the moment, if enough illumination is provided for charging the solar battery after sunrise, manual supplementary charging is not needed, and a charging prompt signal is not needed to be sent at the moment; and when the illumination intensity data in the daytime is lower than the illumination intensity threshold value, or when the sunlight is judged to be insufficient at night, namely, the solar battery is charged by insufficient illumination, the manual supplementary charging is needed at the moment, namely, a charging prompt signal is sent.
For example, an electric quantity early warning signal is sent at 3 o 'clock (night) in the morning, and illumination intensity data is acquired, since the current time is at night, the illumination intensity data is certainly smaller than an illumination intensity threshold value under normal conditions, assuming that the local sunrise time is 7 o' clock, weather forecast information after 7 o 'clock is acquired, if the result is clear, enough illumination is available to charge the solar cell after 7 o' clock, and in this case, a charging prompt signal is not needed to be sent; if the solar battery is in cloudy days or rainy days after 7 o 'clock, the solar battery is not charged with enough illumination intensity after 7 o' clock, and at the moment, a charging prompt signal needs to be sent to prompt manual supplementary charging, so that the situation that the monitoring equipment cannot normally operate due to the defects is avoided to a certain extent.
Referring to fig. 4, as a further embodiment of the control method, after the step of generating the electric quantity warning signal, the method further includes:
acquiring the power consumption of each monitoring device according to the power consumption data of each monitoring device; the power consumption can be calculated by the following formula: power consumption = present power consumption voltage vs present power consumption current;
respectively judging whether the power consumption of each monitoring device is greater than a preset power threshold of the corresponding monitoring device, if so, sending an abnormal signal of the monitoring device to a management terminal; the preset power threshold is the rated power of each monitoring device.
In the above embodiment, after the electric quantity of the solar battery is lower than the preset electric quantity early warning value, the electric power of each monitoring device is calculated according to the electric power data of each monitoring device, and then whether the electric power of the monitoring device is higher than the preset power threshold of the monitoring device is judged, if so, the monitoring device is possibly in an abnormal discharging condition, at the moment, the residual electric quantity of the solar battery is low and is possibly caused by the abnormal increase of the electric power of the monitoring device, and an abnormal signal of the monitoring device is sent to the management terminal, so that a manager can overhaul the monitoring device according to the actual condition.
