Examples
In this embodiment, the electric energy sources are divided into two types: one is a solar power supply system, and the other is a disposable battery power supply.
The two power supply systems are mutually backup and work cooperatively. Solar power supply systems are usually used as the main material, and disposable battery power supply systems are used as the auxiliary materials. When the voltage of the solar power supply system drops and the power is insufficient, the system is automatically switched to a disposable battery system for supplying power, and the solar power system enters a charging state. And after the solar energy system is charged, switching to the solar energy system again for supplying power.
In order to simplify installation and reduce cost and maximally improve the utilization rate of the power supply system, the complementary power supply system of the embodiment should follow the following principles:
1. the solar panel should be mounted in a manner that fits against the surface of the device as much as possible, rather than with additional uprights.
2. The solar panel should be selected as high as possible in the type of conversion efficiency, for example monocrystalline silicon solar energy.
3. The solar panel should be as large as possible in the area of the device surface energy utilization area to maximize the solar output power.
4. The solar energy system uses the ternary lithium battery with small volume and high energy as much as possible. Such as 18650 batteries.
5. The disposable battery is selected according to the actual condition of the equipment, and the battery with small volume and high density, such as a lithium thionyl chloride battery, is selected as much as possible. However, the discharge curve of the battery has a limit, and if the discharge curve does not meet the actual requirements of equipment, the discharge curve of the battery is selected additionally.
6. The battery capacities of the two power supply systems are reasonably distributed according to the actual power consumption condition of the equipment. The whole life cycle of the equipment is as long as possible, and the disposable battery is not required to be replaced.
The embodiment is simultaneously suitable for the following scenes:
1. the power consumption of the device is slightly larger than the solar charging power, and after the electric quantity of the rechargeable battery is used up, the disposable battery can be supported for a long time, so that the rechargeable battery can be fully charged again. This cycle is repeated a number of times.
2. The solar charging power is larger than the equipment power, and can be completely powered by the solar system at ordinary times. However, when the system is in a overcast day or in a poor illumination condition in winter, the disposable battery can be used for replacing power supply, so that the system can work normally.
In this embodiment, the integrated tilt angle monitor is taken as an example, and the integrated power consumption is about 0.5Wh consumed every day.
In the prior art, a disposable battery scheme is used, taking the current 34615 battery with relatively high energy density as an example, 4 34615 batteries are built in, and the total energy of the battery is 3.6V.19Ah.4=273.6Wh. The theoretical endurance of the device is 273.6/0.5= 547.2 days. That is, using 4 34615 batteries to power, the device could theoretically operate for 547.2 days. I.e. half-replacement of the primary battery for approximately 1 year.
In this embodiment, because of the limitation of the surface size, the integrated tilt angle monitor can install a solar cell with power of 1W. The battery composition scheme is 2 34615 disposable batteries+2 18650 rechargeable batteries. Because of the specificity of the installation environment of the integrated tilt monitor, the uncertainty of the installation direction of the integrated tilt monitor determines the uncertainty of the charging efficiency of the solar panel. This embodiment takes two extreme cases as examples:
one is that the average charging power of the solar panel is only 10%, namely 0.1W, and the effective illumination time is 8 hours per day.
In this case, the daily solar energy charge is 0.8Wh, the input energy is larger than the consumption energy, and the equipment can still work continuously. Here we again assume that winter illumination is poor and cannot be charged by solar energy for up to 90 days. During the 90 days, the energy of 2 18650 cells is 3.7v×3.2ah×2= 23.68Wh, and 23.68/0.5= 47.36 days can be used. That is, the remaining 90-47=43 days, and the tilt detector is powered by 2 disposable batteries 34615. While 2 34615 batteries may be continuously powered for 273.6 days. Since only a disposable battery is needed for 43 days per year, the power supply system can be used for 273.6/43=6.36 years. In contrast, in this extreme case, only half a battery change is required for approximately 6 years.
The other is that the position of the solar panel is not ideal, the charging power is only 5 percent, namely 0.05W, and the effective illumination time is 8 hours per day.
In this case, the daily energy input is 0.4Wh, and the daily energy gap is 0.1Wh, compared to the consumption of 0.5Wh by the tilt detector. Then if the charge is full at the time of shipment of 2 18650, then the 4 batteries can be used (136.8+23.68)/0.1= 1604.8 days. About 4 and a half years. If again severe, consider that in extreme cases 90 days in winter cannot be charged, about 2 and a half years may be used.
From the above comparison, it can be seen that the cost of the scheme used in this example is similar to that of the scheme using 4-cell 34615, and is slightly higher and almost negligible. However, the scheme used in this example, even if calculated according to the most extreme case, is used for more than one year higher than the 4-cell 34615 battery scheme. In practical use, the charging efficiency of the solar panel is generally higher than that of the extreme case described above, and the service time is also much longer than that of the calculation described above. By contrast, by using the scheme of the embodiment, the cost is hardly greatly increased, but the period of equipment maintenance and battery replacement can be greatly reduced, so that more cost is saved, and the dependence on human resources is also greatly reduced. Meanwhile, because the solar energy system is integrated and then arranged inside the equipment, an external vertical rod is not needed to be arranged, the installation difficulty is greatly reduced, and the convenience of equipment use is improved.
In the prior art, for low-power consumption equipment, the disposable battery can be used for power supply, and solar energy can also be used for power supply. However, most devices are also powered by disposable batteries due to installation environment and cost issues. The low-power solar complementary power supply system in the embodiment can effectively combine the two systems, and each system needs to be taken, so that the system does not occupy excessive space or greatly increase cost, and the battery does not need to be replaced periodically. The power supply mode of the outdoor low-power consumption monitoring equipment is ideal.
In summary, the utility model provides a low-power solar complementary power supply system for outdoor monitoring, which greatly reduces the period of equipment maintenance and battery replacement on the premise of unchanged cost, thereby saving time and reducing the dependence of daily maintenance of an outdoor monitoring installation environment on human resources; meanwhile, because the solar energy system is integrated in the equipment, no external upright rod is needed for installation, the installation difficulty of the outdoor monitoring equipment box is reduced, and the convenience of the equipment box is improved, so that the solar energy system has a wide application prospect.
It is emphasized that: the above embodiments are merely preferred embodiments of the present utility model, and the present utility model is not limited in any way, and any simple modification, equivalent variation and modification made to the above embodiments according to the technical substance of the present utility model still fall within the scope of the technical solution of the present utility model.
