Description
Technical Field
The invention relates to the technical field of electric light sources, in particular to a solar garden path lamp.
Background
Currently, there are many solar lamps in the market, and the voltage of the lithium battery is directly measured to calculate the residual electric quantity in the lithium battery for self-adjustment of power. However, this method has a disadvantage that the measurement of the lithium battery voltage can only learn the current charging condition, and cannot learn the subsequent charging condition, so that flexible deployment of self-regulating power with long time span cannot be realized. If the power consumption and the power are distributed according to the working time length of 12 hours at night of the current day, if the following days meet the checked weather, the following days cannot be fully charged due to the bad weather, so that the following days are not working due to no power, or the reserved power is insufficient to support the effective working of the lamp.
Disclosure of Invention
The invention aims to provide a solar garden path lamp which can control the normal work of the garden path lamp according to the future weather condition even if weather is bad for a plurality of days, and can provide needed illumination light.
The solar garden path lamp is realized in such a way that the working mode of the path lamp is determined and the path lamp is controlled;
The working mode of the path lamp with the solar device and the control device is determined as follows:
The control device acquires weather forecast of a plurality of days in the future, determines an electricity consumption number according to the weather forecast of the plurality of days in the future, and determines a daily working mode of the path lamp in the period by combining the storage capacity of the storage battery of the solar device detected by the control device;
the control of the path lamp with the solar device and the control device is to control the operation of the path lamp by the control device according to the determined working mode;
The power consumption number X is determined according to the weather conditions of weather forecast:
setting the original electricity consumption number X as 100%;
Determining whether to adjust the power consumption number X according to the interval days d between sunny days in weather forecast of a plurality of days in the future, if d is larger than d 0, adjusting the power consumption number X, wherein d 0 is the number of days when the electric energy charged in sunny days can be used for maintaining full-load power supply for the path lamp;
d > d 0, the adjustment of the power consumption number X is determined in such a way that:
X= (Y 1+ Y2+…… Yd ）* d0/d, d is the number of days of the interval between sunny days in the weather forecast for several days in the future, if X >100%, x=100%
Y d is the average solar irradiance per day between sunny days in the weather forecast for the next days;
The control of the path lamp is that the control device controls the power supply circuit to output a power supply with voltage V 1 to the path lamp according to the working mode, the set working time period and the triggering condition of a certain day in the period, namely, the voltage V 1=V0*X,V0 is the voltage when the path lamp works at full load.
The charge quantity Q of the solar charging plate is in linear relation with the solar irradiance epsilon, the solar panel A and the solar conversion rate eta, namely Q=epsilon, A and eta;
When the adopted solar charging panel can be fully charged with the storage battery under the condition of sunny days, the duration of the storage battery meets the requirement of full-load illumination electricity consumption at night of at least 1 day (which can be realized by the technology certainly), and the output voltage of the full-load illumination electricity consumption is V 0, so that the electric energy stored in the storage battery after solar power generation can meet the requirement of the full-load illumination electricity consumption at night every day on sunny days;
When the weather is not sunny, the solar charging plate cannot be filled with the storage battery, and as the solar panel A and the solar conversion rate eta are not affected by weather, only the solar irradiance epsilon is affected by weather and can be approximately determined according to weather forecast, and in this case, the average epsilon 1 of the solar irradiance epsilon between sunny days in the weather forecast of several days in the future can be approximately obtained;
Since the charge amount Q of the solar charging panel is in a linear relationship with the solar irradiance epsilon, the solar panel surface a and the solar conversion rate eta, the output power is reduced by reducing the output voltage in the weather forecast of the next days, namely the output voltage is reduced to V 1=V0 X, because the ratio Q 1/ Q0 of the charge amount Q 1 of the solar charging panel to the charge amount Q 0 of the solar charging panel of the sunny days in the weather forecast of the same days is also the ratio epsilon 1/ ε0 of the average epsilon 1 to epsilon 0 of the sunny days.
Preferably, the output voltage is adjusted such that the rectified voltage V 2=V0*X*R,R=（Vp-Vz）/(Vy-Vz),Vz is a cut-off voltage, V y is an expected voltage, V p is a rectified voltage (i.e., an actual measured voltage), and R is a rectification coefficient.
While power self-regulation based on weather forecast provides the self-regulation capability of the path light for a long time span, if the weather forecast is inaccurate, resulting in a lower actual charge than expected, it may result in the path light not being able to operate as expected on a2 nd sunny day. Therefore, a method for calculating the electric quantity of the lithium battery by voltage measurement is introduced, and the charging condition calculation result based on weather forecast is verified every day so as to ensure the realization of continuous voyage.
Depending on the voltage and charge relationship of the lithium battery (assuming that the charge energy charged on a sunny day can be maintained to power the path lamp 1 time at full load),
Current lithium battery remaining capacity percentage= (correction voltage-cut-off voltage)/(full voltage-cut-off voltage)
Is available in the form of ：Qp/ Qm=（Vp-Vz）/(Vm—Vz),Vp=（（Qp/ Qm）*（Vm-Vz））+ Vz
V m is the full voltage
Q p is the current lithium battery remaining capacity
Q m is the full charge of the lithium battery
Likewise, the
Percentage of remaining capacity of expected lithium battery= (expected voltage-cut-off voltage)/(full voltage-cut-off voltage)
Is available in the form of ：Q1/ Qm=（Vy-Vz）/(Vm—Vz),Vy=（（Q1/ Qm）*（Vm-Vz））+ Vz
Q 1 is the expected lithium battery remaining power (i.e., the charge of the solar panel between sunny days in the weather forecast for several days in the future)
T1= Q1/（W* X）
Tp= Qp/（W* X*R）
T 1 is the expected duration, T p is the duration after correction, Q p is the charge after correction, and W is the full power of the path lamp
In the case of the requirement of T 1= Tp,
Q1/（W* X）= Qp/（W* X*R）
R= Qp/ Q1=（（Vp-Vz）/(Vm—Vz)）/（（Vy-Vz）/(Vm—Vz)）=（Vp-Vz）/（Vy-Vz）.
Preferably, the path lamps with the solar device are provided with a plurality of path lamps, the operation of the plurality of path lamps adopts a self-linkage mode, namely when a microwave probe of one path lamp detects that a person appears in an induction area, the lamp can be lightened, and meanwhile, a BLE Mesh broadcast message is sent to other lamp nodes of the same Mesh network in a communication range to inform other solar courtyard path lamps of synchronous lightening;
When a path light receives a notification message, it will, while on, forward the message again to other path lights within its communication range, effecting a jump over the communication network.
The microwave probes of the path lamps are far away from the target, and the path lamps can be automatically and synchronously lightened as long as the distance between the microwave probes and the target is short, so that the distance limitation is broken.
The weather forecast data is transmitted to the path lamp and the self-linkage of the path lamp is realized through Bluetooth BLE Mesh communication.
Preferably, a weather forecast data synchronizing function is used in the App, when the weather forecast data synchronizing function is used in the App, the user can use the current position or input the postal code of the target position, the App can request weather forecast data of the target position through the cloud API, and when the App requests the cloud API to complete, after obtaining the weather forecast data of the target position, the App sends the weather forecast data to the selected single or multiple path lamps through the bluetooth BLE Mesh;
After the path lamp receives the weather forecast data, a corresponding working mode is determined according to the weather conditions in the received future period.
Preferably, the path lamp has two working modes, one is a normal mode, the lamp is in an off state at ordinary times, the lamp is turned on when the induction is triggered, and the lamp is turned off again after the induction is not triggered for a period of time; the other is a micro-lighting mode, the lamp is in a micro-lighting state at ordinary times, and becomes a high-lighting state when the induction is triggered, and the lamp is restored to the micro-lighting state after the induction is not triggered for a period of time.
Preferably, based on bluetooth BLE Mesh communication, a user can search unpaired lamp nodes and pair the unpaired lamp nodes through a scheme matched with a mobile phone App, after pairing is completed, the user can perform mode control, brightness control, timing closing setting and weather forecast data synchronization on the lamps through the mobile phone App, and besides each lamp node can be independently controlled, the user can also group all paired lamp nodes and simultaneously control the lamp nodes of the whole group.
Preferably, the voltage V p output by the storage battery to the path lamp is calculated and corrected in an auxiliary manner according to the sunlight irradiation condition of the environment where the path lamp is located, so as to ensure that the path lamps with different charging conditions in the same area due to environmental factors can also have approximate duration.
Because of uncertainty of outdoor environment, even lamps in the same area have different charging conditions possibly caused by factors such as shade, eave, sunlight irradiation angle and the like, the auxiliary calculation correction exists, and the lamps in the same area with different charging conditions caused by environmental factors can also have approximate duration. After the final calculation is completed, the current power is set to the calculated optimal power.
Compared with the prior art, the invention has the advantages that even if the weather is bad for a plurality of days continuously, the courtyard path lamp can be controlled to work normally according to the weather condition in the future, and the courtyard path lamp can provide the required illumination light.

Detailed Description
The solar garden path lamp of the present invention will now be described in further detail with reference to the accompanying drawings and examples:
As shown in fig. 1 and 2, the solar garden path lamp is realized by determining the working mode of the path lamp and controlling the path lamp;
The working mode of the path lamp with the solar device and the control device is determined as follows:
The control device (MCU) 1 obtains weather forecast of a plurality of days in the future, determines an electricity consumption number according to the weather forecast of the plurality of days in the future, and determines a daily working mode of the path lamp 4 in the period through the control device 1 in combination with the storage capacity of the storage battery 3 of the solar device 2 (the solar garden path lamp is provided with) detected by the control device 1;
The control of the path lamp 4 with the solar device 2 and the control device 1 is to control the operation of the path lamp 4 by the control device according to the determined operation mode;
The power consumption number X is determined according to the weather conditions of weather forecast:
setting the original electricity consumption number X as 100%;
determining whether to adjust the power consumption number X according to the interval days d between sunny days in weather forecast of a plurality of days in the future, if d is larger than d 0, adjusting the power consumption number X, wherein d 0 is the number of days when the electric energy charged in sunny days can maintain full-load power supply to the path lamp 4;
d > d 0, the adjustment of the power consumption number X is determined in such a way that:
X= (Y 1+ Y2+…… Yd ）* d0/d, d is the number of days of the interval between sunny days in the weather forecast for several days in the future, if X >100%, x=100%
Y d is the average solar irradiance per day between sunny days in the weather forecast for the next days;
Weather forecast, the format is fixed, so the type is basically fixed, such as sunny days, sunny-cloudy days, rainy days, foggy days and the like, and cloud, humidity, rainfall or snow are matched, and the three parameters of cloud, humidity, rainfall or snow are directly related to solar irradiance, and are subjected to long-term data collection (the product is mainly sold in the United states, and is analyzed by using data provided by a National Renewable Energy Laboratory (NREL) in the United states as raw data, the raw data are daily data of solar irradiance, cloud coverage, related humidity and snow fall, the total data is 730 days, the data time range is January 1, 2020-December 31, 2023), and the data are analyzed by a function of binomial fitting:
Y=CO+C1*X+C2*X2
As shown in fig. 3, the relationship between the cloud cover, humidity, rainfall or snow and the solar irradiance is obtained, so as to obtain the average value epsilon 1 of the solar irradiance epsilon corresponding to different weather forecast, and the solar irradiance epsilon 0 in sunny days,
Because solar irradiance, weather forecast and corresponding cloud amount, humidity, rainfall or snow amount of different places are objectively existed and are objectively known, the relation between the solar irradiance and the weather forecast of the places used by the technology of the patent application can be obtained through collecting and analyzing data for a period of time,
The control of the path lamp 4 is that the control device 1 controls the power supply circuit to output a power supply with voltage V 1 to the path lamp according to the working mode, the set working time period and the triggering condition of a certain day in the period, namely, the voltage V 1=V0*X,V0 is the voltage when the path lamp works at full load.
The charge quantity Q of the solar charging plate is in linear relation with the solar irradiance epsilon, the solar panel A and the solar conversion rate eta, namely Q=epsilon, A and eta;
when the adopted solar charging panel can be fully charged with the storage battery under the condition of sunny days, and the duration of the storage battery 3 meets the requirement of full-load illumination electricity consumption at night of at least 1 day (which can be realized by the technology certainly), the output voltage of the full-load illumination electricity consumption is V 0, so that the electric energy stored in the storage battery 3 after solar power generation can meet the requirement of the full-load illumination electricity consumption at night every day on sunny days;
In the case of non-sunny days, the solar charging panel cannot be fully charged with the storage battery 3, and as the two parameters of the solar panel A and the solar conversion rate eta are not affected by weather, only the solar irradiance epsilon is affected by weather and can be approximately determined according to weather forecast, in this case, the average epsilon 1 of the solar irradiance epsilon between sunny days in the weather forecast of several days in the future can be approximately obtained;
Since the charge amount Q of the solar charging panel is in a linear relationship with the solar irradiance epsilon, the solar panel surface a and the solar conversion rate eta, the output power is reduced by reducing the output voltage in the weather forecast of the next days, namely the output voltage is reduced to V 1=V0 X, because the ratio Q 1/ Q0 of the charge amount Q 1 of the solar charging panel to the charge amount Q 0 of the solar charging panel of the sunny days in the weather forecast of the same days is also the ratio epsilon 1/ ε0 of the average epsilon 1 to epsilon 0 of the sunny days.
Here, d 0 is not more than 2 but not less than 1. The larger d 0 is, the larger the capacity of the solar charging equipment is, the higher the cost is, the low cost performance of the product is easy to cause, the proportion of continuous bad weather conditions is not large in one year, the long time is not required, if the capacity of the solar charging equipment is easy to cause idle equipment capacity to cause waste, d 0 is not more than 2 but not less than 1 is adopted, thus the cost can be saved, the capacity of the equipment can be fully utilized, the idle equipment capacity is avoided, the waste is caused, meanwhile, the output power is reduced through proper adjustment, the illumination requirement can be met, and the illumination requirement can be met under the condition of continuous bad weather.
Preferably, the output voltage is adjusted such that the rectified voltage V 2=V0*X*R,R=（Vp-Vz）/(Vy-Vz),Vz is a cut-off voltage, V y is an expected voltage, V p is a rectified voltage (i.e., an actual measured voltage), and R is a rectification coefficient.
While power self-regulation based on weather forecast provides the self-regulation capability of the path light for a long time span, if the weather forecast is inaccurate, resulting in a lower actual charge than expected, it may result in the path light not being able to operate as expected on a2 nd sunny day. Therefore, a method for calculating the electric quantity of the lithium battery by voltage measurement is introduced, and the charging condition calculation result based on weather forecast is verified every day so as to ensure the realization of continuous voyage.
Depending on the voltage and charge relationship of the lithium battery (assuming that the charge energy charged on a sunny day can be maintained to power the path lamp 1 time at full load),
Current lithium battery remaining capacity percentage= (correction voltage-cut-off voltage)/(full voltage-cut-off voltage)
Is available in the form of ：Qp/ Qm=（Vp-Vz）/(Vm—Vz),Vp=（（Qp/ Qm）*（Vm-Vz））+ Vz
V m is the full voltage
Q p is the current lithium battery remaining capacity
Q m is the full charge of the lithium battery
Likewise, the
Percentage of remaining capacity of expected lithium battery= (expected voltage-cut-off voltage)/(full voltage-cut-off voltage)
Is available in the form of ：Q1/ Qm=（Vy-Vz）/(Vm—Vz),Vy=（（Q1/ Qm）*（Vm-Vz））+ Vz
Q 1 is the expected lithium battery remaining power (i.e., the charge of the solar panel between sunny days in the weather forecast for several days in the future)
T1= Q1/（W* X）
Tp= Qp/（W* X*R）
T 1 is the expected duration, T p is the duration after correction, Q p is the charge after correction, and W is the full power of the path lamp
In the case of the requirement of T 1= Tp,
Q1/（W* X）= Qp/（W* X*R）
R= Qp/ Q1=（（Vp-Vz）/(Vm—Vz)）/（（Vy-Vz）/(Vm—Vz)）=（Vp-Vz）/（Vy-Vz）.

After the final calculation is completed, the current power is set to the calculated optimal power.
As shown in fig. 2, the MCU of the control device 1 is Le Xin ESPRESSIF ESP 32-C3, which has bluetooth function, supporting BLE Mesh communication.
The microwave probe 5 (microwave motion detection module) is a Y18EA2251 module of an EDC18 series microwave motion detection module of the quick-detection EASYDETECT, the signal output of the sensing module is connected to the MCU, the signal output is at a low level at ordinary times, and the signal output becomes at a high level when the motion detection triggers.

The MCU is connected with the voltage output end of the lithium battery, and the current output voltage of the lithium battery is detected and calculated through the ADC function.
The battery 4 supplies an operating power to the control device 1 and the microwave probe 5 via the voltage stabilizing circuit 8.
The MCU is connected with a signal output pin of the microwave movement detection module. In a conventional mode, the MCU controls the solar garden path lamp to be turned off when the output pin of the sensing module is in a low level, and controls the lamp to be turned on when the level is detected to be pulled up, and meanwhile, other nearby lamps are notified through BLE Mesh broadcast information, so that the other lamps are also turned on synchronously.
