The embodiment of the application provides a street lamp power supply management method, which is executed by an electronic device or a server, and the method comprises steps S101 to S104 with reference to fig. 1, wherein:
step S101, after the electric quantity of the energy storage battery is determined to be smaller than a preset low electric quantity threshold value, switching the power supply source to the commercial power, wherein the low electric quantity threshold value is the minimum value of switching the power supply source from the energy storage battery to the commercial power.
Referring to fig. 2, in the embodiment of the present application, the checking of the electric quantity of the energy storage battery may be performed in real time, or may be performed at preset time intervals, and the embodiment of the present application is not limited in any way. Specifically, the power supply circuit of the street lamp should have two types, namely, the power supply circuit of the mains supply to the street lamp and the power supply circuit of the energy storage battery to the street lamp. Likewise, there should also be a charging circuit of the solar photovoltaic panel to the energy storage battery.
Further, when the electric quantity of the energy storage battery is within a preset interval, the power supply source of the street lamp is switched from the energy storage battery to the commercial power, and the low electric quantity threshold value is the minimum value within the preset interval. However, the specific value of the low battery threshold is not specifically limited in the embodiments of the present application.
And S102, monitoring the electric quantity of the energy storage battery, and determining the power shortage duration of the energy storage battery smaller than a low electric quantity threshold.
In the embodiment of the application, the monitoring of the electric quantity of the energy storage battery can be carried out in real time or at preset intervals. And starting timing from the moment when the electric quantity of the energy storage battery is detected to be smaller than the low electric quantity threshold value for the first time so as to determine the time length when the energy storage battery is smaller than the low electric quantity threshold value.
Step S103, determining whether the power-shortage duration is greater than a preset critical duration, where the critical duration is the shortest duration that the energy storage battery can be damaged under a low electric quantity.
In the embodiment of the present application, for the specific duration of the critical duration, no specific limitation is made in the embodiment of the present application, as long as the probability of damage to the energy storage battery is reduced.
And step S104, if so, controlling the commercial power to charge the energy storage battery.
In this application embodiment, if the energy storage cell continues for a preset time period in a low power state where the power is less than the preset threshold, it indicates that the energy storage cell is not charged by the solar photovoltaic panel within the preset time period, that is, there may be no weather of sunlight or a charging loop of the solar photovoltaic panel has a fault within the critical time period.
After the energy storage battery is smaller than the low-electricity threshold value, the energy storage battery is in a low-electricity power-shortage state, and a power supply source of the street lamp is switched to commercial power from the energy storage battery; at this moment, the battery is probably charged by the photovoltaic board, also probably not charges, and electronic equipment can monitor energy storage battery's electric quantity to when judging energy storage battery's insufficient voltage time and being greater than critical duration, charge for energy storage battery through the commercial power, further increase in the time of the insufficient voltage state with the reduction energy storage battery, can reduce the probability that energy storage battery damaged, and then can reduce new forms of energy street lamp's extra maintenance cost.
Further, in order to reduce the actual power consumption during the charging process of the energy storage battery, before step S104, step SA1 (not shown) to step SA4 (not shown) are further included, wherein:
step SA1, obtaining the position of an energy storage battery;
step SA2, weather information of the position in a later preset period is obtained based on the position, and the preset period is less than or equal to a critical time.
Specifically, a GPS positioning device may be preset at a location where the street lamp is set to obtain a location of the energy storage battery; and because the positions of the street lamp and the energy storage battery are usually fixed, the position of the energy storage battery can be preset for storage. For the specific duration of the preset period, the specific duration is only required to be less than or equal to the critical duration; for example, if the critical duration is 15 days, the predetermined period may be 14 days.
After the position of the energy storage battery is determined, weather information of the position in a preset period is determined based on the position of the energy storage battery, and the weather information comprises various weather types and illumination duration.
Step SA3, judging whether the weather information meets weather of a first preset condition, wherein the first preset condition is that sunlight exists to charge the energy storage battery;
and step SA4, if not, controlling the commercial power to charge the energy storage battery.
Specifically, the weather of the first preset condition may be weather with sunlight, such as sunny days and cloudy sunny days, so that the energy storage battery is charged through the solar photovoltaic panel. However, the specific type of weather of the first preset condition is not specifically limited in detail in the embodiment of the present application. When there is no weather of the first preset condition in the preset period, it is indicated that, in the preset period later, the solar photovoltaic panel cannot charge the energy storage battery, and therefore, the energy storage battery needs to be charged by the commercial power, so that the electric quantity of the energy storage battery is maintained above the low electric quantity threshold.
If the energy storage battery is charged by controlling the commercial power, the critical duration of the low-power state of the energy storage battery, which is smaller than the preset threshold value, can be determined, then the charging needs to be performed at this time, so that the probability that the energy storage battery enters the low-power state again due to the fact that the weather meeting the first preset condition does not exist in the later preset period is reduced, and the probability of damage to the energy storage battery is further reduced.
Further, if there is weather meeting the first preset condition in the weather information, the steps further include steps SA5 (not shown in the figure) and SA6 (not shown in the figure), wherein:
step SA5, determining the shortest interval duration of the weather meeting the first preset condition from the current time.
Specifically, if there is weather meeting a first preset condition in a plurality of time periods in a preset period, only the time period closest to the current time is acquired, and the shortest interval duration from the current time is determined based on the time period. If only the weather type corresponding to one time period exists, the interval duration from the time period to the current time is the shortest interval duration.
And step SA6, determining the charging capacity of the energy storage battery based on the shortest interval duration.
Specifically, in order to save the electric quantity of the energy storage battery, the communication device is also powered by the mains supply in the state that the street lamp is powered by the mains supply, so that only the self-loss of the energy storage battery in unit time needs to be considered. And meanwhile, the electric quantity to be charged is determined based on the current electric quantity of the energy storage battery and the shortest interval duration. For example, if the self-loss of the energy storage battery is 5% of the electric quantity per 24 hours, the current electric quantity is 18%, and the preset threshold is 20%, and the shortest interval duration is 72 hours, the electric quantity that the commercial power needs to charge the energy storage battery should be at least 17%, that is, after the commercial power charges the energy storage battery, the electric quantity of the energy storage battery should be at least 35%.
Further, the street lamp power supply management method further comprises step SB1 (not shown in the figure) and step SB2 (not shown in the figure), wherein:
step SB1, when the electric quantity of the energy storage battery is larger than a low electric quantity threshold value, weather information of a position in a preset period is obtained;
step SB2, if there is no weather meeting the first preset condition in the preset period, in the following preset period, controlling the power supply of the street lamp to be the commercial power all the time.
Specifically, if in the later preset period, there is not the weather that accords with first preset condition, the commercial power can charge for energy storage battery, and although energy storage battery's electric quantity is greater than preset threshold value this moment, in the preset period, energy storage battery's electric quantity can't supply through the solar photovoltaic board, therefore, adopt the commercial power to supply power for the street lamp, can reduce the waste of electric energy.
Further, in order to reduce the illumination of the street lamp when needed, so as to provide convenience for pedestrians and vehicles, and also reduce unnecessary power consumption of the street lamp, the street lamp power management method further includes steps SC1 (not shown) to SC4 (not shown), wherein:
step SC1, in a preset working period, determining whether pedestrians or vehicles exist in a preset area;
and step SC2, if the current signal exists, controlling the street lamp to illuminate.
In particular, the preset duty cycle may be a duty cycle that is set at a preset time period, for example at 18 pm: 00 to 5:00 in the morning, which is a preset working period; of course, the preset work cycle may also be a work cycle in which the setting position of the street lamp is automatically determined based on the brightness of the environment, which is not specifically limited in the embodiment of the present application. In a preset working cycle, the street lamp is allowed to be lighted for illumination, and in a time period outside the preset working cycle, the street lamp is not allowed to be lighted.
When the existence of pedestrians and vehicles is detected, the power supply circuit of the street lamp is opened, and the street lamp illuminates to provide convenience for the pedestrians and the vehicles.
Step SC3, if not, judging whether a second preset condition is met; the second preset condition comprises that the weather type of the received normally-bright signal or the position is a preset abnormal weather type;
and step SC4, if yes, controlling the energy storage battery or the commercial power to supply power to the street lamp and controlling the street lamp to illuminate.
If no pedestrian exists, the street lamp can be kept normally bright for illumination after receiving the constant signal. Meanwhile, if the current weather is detected to be a preset abnormal weather type, the street lamp can be kept in a normally-on state, so that a better view field is provided for far pedestrians and vehicles.
Further, step SC1 may specifically include step SC11 (not shown in the figure) and step SC12 (not shown in the figure), wherein:
step SC11, acquiring road images collected by monitoring equipment preset in a preset area based on the position;
step SC12, performing object recognition on the road image, and determining whether there is a human body object or a vehicle object.
Specifically, a road image is collected through monitoring equipment at a preset position, target identification is carried out on the road image, the category of each target in the road image can be obtained, whether a human body category or a vehicle target category exists or not is further judged, and whether pedestrians or vehicles exist in a preset area or not can be further judged.
Furthermore, by carrying out target identification on the road image acquired by the monitoring equipment, whether a human body or a vehicle target exists in the preset area can be accurately determined; meanwhile, the preset ranges corresponding to the adjacent street lamps can be overlapped or the same, so that the same monitoring device can correspond to a plurality of street lamps, and the control efficiency is improved and the electric quantity consumption is reduced.
Further, step SC1 further includes step SC13 (not shown in the figure) and step SC14 (not shown in the figure), wherein:
step SC13, collecting sound information in a preset area;
step SC14, determining whether there is a pedestrian or a vehicle in the preset area based on the sound information in the preset area.
Specifically, the size of the sound can be determined through the collected sound information, meanwhile, the comparison is performed based on a preset volume threshold, and if the size of the sound is larger than the volume threshold, it can be determined that a pedestrian or a vehicle exists in the preset area.
Or analyzing the sound information, and judging whether human sound or vehicle sound exists in the sound information according to the range of the tone color and the tone frequency, so that the judgment result of whether pedestrians or vehicles exist in the preset area can be obtained.
