The utility model relates to an outdoor thing networking weather station, concretely relates to can be automatically to the outdoor thing networking weather station of solar energy power supply of focusing.

Background

An outdoor internet of things weather station is an internet of things data acquisition system widely applied to field planting, mountain and forest geological disaster protection and field meteorological information acquisition in recent years. The method comprises the steps that conventional meteorological information is measured through an atmospheric pressure sensor, an atmospheric temperature sensor, an atmospheric humidity sensor, a rainfall sensor, an illumination sensor, a wind speed sensor and a wind direction sensor, soil temperature and humidity information is measured through the soil temperature and humidity sensor, analog/digital signals measured by the sensors are converted into wireless communication signals such as 2G/3G/4G or NB-IOT/Lora through a data acquisition unit, the wireless communication signals are uploaded to a cloud server through a mobile operator base station or an Internet of things relay node, and after required data are downloaded from the cloud server through a background remote server, the data are analyzed according to a corresponding communication protocol, and real-time meteorological soil moisture information is obtained. Because outdoor thing networking soil moisture content weather station installs usually in should not bury specially (erect) the region of establishing the power supply cable, so outdoor thing networking soil moisture content weather station generally adopts the solar energy power supply at present, promptly through the photovoltaic board via special charging and discharging circuit, under the condition that has enough light intensity to shine, maintains the weather station work on one side, gives battery charging on one side, and when night or light intensity were not enough, then by the work of battery maintenance weather station.

However, under the influence of the revolution of the earth around the sun and the rotation of the earth, the sun is located at different angles and different directions in the sky every day and at different moments, so that most of photovoltaic panels installed at fixed angles and directions are capable of being vertically irradiated by near sunlight every day and effectively utilizing the sunlight illumination time, which is substantially short, generally only two hours or three hours before and after noon, so that it is difficult to ensure that the battery of the equipment can be fully charged, and especially in winter and rainy season, the outdoor meteorological station is often powered off and the battery is power-off due to the short working time of the photovoltaic panel, and the normal use of the equipment is seriously influenced, for example:

As shown in fig. 2 and 3, a plurality of first light sensors 25 are uniformly and orderly distributed on the surface of the hemispherical first light sensor spherical array 1 along different warps and wefts, a light sensor is arranged in the center of the first light sensor spherical array 1, 8 light sensors are arranged around the light sensor, 8 light sensors are arranged at the periphery of the light sensor, namely 8 light sensors at the inner ring and 8 light sensors at the outer ring, or the number of the light sensors can be set according to actual conditions, but at least one circle of the light sensors, and the first light sensors 25 are photoresistors.

When the sun is located right above the first spherical illumination sensor array 1, the resistance of the first illumination sensor 25 is reduced, and at this time, the rotation control stepping motor 7 does not work, and when the sun is located in the northeast direction as shown in fig. 3, sunlight can only irradiate the half spherical surface of the illumination sensor 25, so that the resistance of the illumination sensor 25 is reduced, and the illumination sensor 25 at the backlight side cannot receive direct sunlight and can only receive scattered light from other directions, so that the amplitude of the reduction of the resistance is far inferior to that at the side directly irradiated. As shown in fig. 3, the black solid circles indicate the illumination sensor 25 that is directly illuminated, and the white hollow circles indicate that the illumination sensor 25 is not directly illuminated, so that the illumination direction can be determined by taking the connection direction of the centers of the illumination sensors 25 with the resistances significantly reduced by several circles.

An outer rotating shaft 11 is arranged between the upper platform 6 and the middle platform 14, the outer rotating shaft 11 is welded on the equipment rod 24 through an upper bearing 10 and a lower bearing 12, the upper bearing 10 is a ball bearing, the lower bearing 12 is a thrust bearing, the middle platform 14 is fixed on a pitching control box 13 through bolts, a pitching control stepping motor 27, a pitching control driving gear 28 and a pitching control driven gear 29 are installed in the pitching control box 13, the pitching control stepping motor 27 is installed on a motor base 30 through bolts, the motor base 30 is connected with the middle platform 14 through welding or bolts, the pitching control box 13 is connected with a pitching control hinge 15 through hinges, an integrated equipment box 19 is installed at the other end of the pitching control hinge 15, and an internet of things data acquisition and controller 18 is arranged in the integrated equipment box 19, the outer wall of integration equipment box 19 is equipped with photovoltaic board 16, photovoltaic board 16 is fixed through bolt or glue on the integration equipment box 19, photovoltaic board 16 passes through connecting rod 23 and connects second light sensor annular array 17, second light sensor annular array 17's outer loop side is equipped with half a circle evenly distributed's second light sensor 26.

Because the illumination direction obtained by the first illumination sensor spherical array 1 is converted by the photoresistor and is an electric signal, the illumination direction is processed by the internet of things data acquisition and controller and is sent to the rotation control stepping motor 7, the rotation control stepping motor 7 rotates for the corresponding number of turns, the rotation control stepping motor 7 drives the rotation control driving gear 8 to rotate, the rotation control driving gear 8 drives the rotation control driven gear 9 to rotate, the outer rotating shaft 11 is driven to rotate, and therefore the photovoltaic panel 16 is adjusted to face the sun.

The pitch angle of the photovoltaic panel 16 also needs to be adjusted for more precise alignment with the sun.

Firstly, the illumination angle of the sun needs to be measured, and the illumination angle measurement is realized through a 17 illumination sensor annular array and a 18 Internet of things data acquisition and controller.

When the photovoltaic panel is adjusted to the direction of the sun, the normal direction of the photovoltaic panel 16 needs to be adjusted to be consistent with the incident direction of the solar rays, so that the photovoltaic panel 16 can be regarded as direct sunlight. When the sun is at an angle, as shown in fig. 3, the annular array of light sensors 17 is bolted or welded to the photovoltaic panel 16 by a rigid connecting rod 23, and the annular array of light sensors 17 is perpendicular to the photovoltaic panel 16.

When the angle of the photovoltaic panel 16 is not directly opposite to the sun, the resistance of the plurality of second illumination sensors 26 directly illuminated by the sun is smaller, and the resistance of the plurality of second illumination sensors 26 is obviously larger because the plurality of second illumination sensors 26 are not directly illuminated, so that the included angle α formed by the photovoltaic panel 16 and the direct light direction can be calculated according to the number of the second illumination sensors 26 not directly illuminated. It is obvious that the more the number of the second illumination sensors 26 is and the more densely the distribution is, the higher the accuracy of the measurement angle is. In practice, the number of second illumination sensors 26 may be arranged according to the requirements of cost and accuracy.

Once the included angle α is obtained, the second illumination sensor 26 can give a corresponding electrical signal to the 18 internet of things data acquisition and controller, and the 18 internet of things data acquisition and controller gives an instruction for controlling the pitch angle of the photovoltaic panel to the pitch control box 13.
