背景技术 Background technique
节能减排、低碳生活已成为人们所关注的问题，太阳能作为一种新兴的绿色能源，正得到迅速发展与应用。利用太阳能电池板收集太阳能并进行光伏发电，是太阳能应用的一个重要内容。有研究表明，通过太阳跟踪并使太阳能电池板时刻与太阳入射光线垂直，比固定安装太阳能电池板的太阳能接受率提高37%。为实现太阳能电池板跟随太阳转动，目前研制出了很多种太阳跟踪机构以及相应的太阳跟踪传感器。但大多数太阳跟踪传感器均是针对某种特定的太阳跟踪机构而设计，其普适性受到一定的限制，将其应用于其它类型太阳跟踪机构的效果不理想，尤其是对于专利（专利号ZL 201110103316.X）所述的利用丝杠传动、分别从东西和南北两个方向驱动太阳能电池板转动的双轴太阳跟踪机构。 Energy conservation, emission reduction, and low-carbon life have become issues of concern to people. Solar energy, as an emerging green energy, is being rapidly developed and applied. The use of solar panels to collect solar energy and generate photovoltaic power is an important part of solar energy applications. Studies have shown that by tracking the sun and making the solar panels perpendicular to the incident light of the sun at all times, the solar acceptance rate of solar panels is 37% higher than that of fixed solar panels. In order to realize the rotation of the solar panel following the sun, many kinds of sun tracking mechanisms and corresponding sun tracking sensors have been developed. However, most of the sun tracking sensors are designed for a specific sun tracking mechanism, and its universality is limited, and the effect of applying it to other types of sun tracking mechanisms is not ideal, especially for the patent (Patent No. ZL 201110103316.X), a two-axis sun-tracking mechanism that uses screw drive to drive solar panels to rotate from east to west and north to south.

Accuracy, thereby improving the sun tracking accuracy; at the same time, through the cylindrical base 3 and the single-headed copper column 7 inside, it is convenient to install corresponding circuits and components inside the sun tracking sensor.
本实用新型的工作原理是：将所述光电式太阳跟踪传感器安装于太阳跟踪机构上（例如此太阳跟踪机构可见专利ZL 201110103316.X），使所述圆柱形底座3的下底面平行了太阳能电池板，而且所述光电探头2所在的2个方向应分别平行于东西、南北方向，同时通过接口电缆4分别与外部电源（DC1.8V~DC5.5V）以及外部控制器（如MSP430F2132单片机）的I/O端口和ADC接口相连。外部控制器通过其I/O端口对ADG706的选择控制端A0、A1、A2和A3进行控制，可在任意时刻实现ADG706的S8、S9、S10、S11、S12、S13、S14、S15和S16端口中的任意一个与公共端D连通，从而可在任意时刻控制所述9个光电探头2中的光敏电阻R1、R2、R3、R4、R5、R6、R7、R8、R9中的任意一个与电阻R19构成电阻分压电路，即可在任意时刻选择9个光电探头2中的任意一个进行光电检测。当某个光电探头2感知的光强增大时，其内部的光敏电阻的阻值变小，从而电阻R19上的电压变大，ADG706公共端D的输出电压增大，即该光电探头2的光电检测值变大。进行太阳跟踪时，分别在所述光电探头2所在的2个方向上，通过外部控制器（如MSP430F2132单片机）逐个控制每个方向上的5个光电探头2进行光电检测，并对其检测结果进行相互比较，然后根据比较结果，发出控制指令使太阳跟踪机构驱动太阳能电池板向最大光电检测值所对应的光电探头2所在的方位转动。当在2个方向上均得出所述9个光电探头2中最中间的光电探头2的光电检测值最大时，则认为太阳光垂直入射太阳能电池板。 The working principle of the utility model is: install the photoelectric sun tracking sensor on the sun tracking mechanism (for example, this sun tracking mechanism can be seen in patent ZL 201110103316.X), so that the lower bottom surface of the cylindrical base 3 is parallel to the solar cell Board, and the two directions where the photoelectric probe 2 is located should be parallel to the east-west and north-south directions respectively, and at the same time connect with the external power supply (DC1.8V~DC5.5V) and the external controller (such as MSP430F2132 single-chip microcomputer) through the interface cable 4 The I/O port is connected to the ADC interface. The external controller controls the selection control terminals A0, A1, A2 and A3 of the ADG706 through its I/O port, and the S8, S9, S10, S11, S12, S13, S14, S15 and S16 ports of the ADG706 can be realized at any time Any one of them is communicated with the common terminal D, so that any one of the photosensitive resistors R1, R2, R3, R4, R5, R6, R7, R8, R9 in the nine photoelectric probes 2 can be controlled at any time to connect with the resistor R19 constitutes a resistor voltage divider circuit, so that any one of the nine photoelectric probes 2 can be selected for photoelectric detection at any time. When the light intensity sensed by a certain photoelectric probe 2 increases, the resistance value of its internal photoresistor becomes smaller, so that the voltage on the resistor R19 becomes larger, and the output voltage of ADG706 common terminal D increases, that is, the output voltage of the photoelectric probe 2 The photoelectric detection value becomes larger. When performing sun tracking, in the two directions where the photoelectric probes 2 are located, the five photoelectric probes 2 in each direction are controlled one by one by an external controller (such as MSP430F2132 single-chip microcomputer) to perform photoelectric detection, and the detection results are analyzed. They are compared with each other, and then according to the comparison result, a control command is issued to make the sun tracking mechanism drive the solar panel to rotate to the orientation of the photoelectric probe 2 corresponding to the maximum photodetection value. When the photodetection value of the middlemost photoelectric probe 2 among the nine photoelectric probes 2 is the largest in both directions, it is considered that the sunlight is vertically incident on the solar cell panel.
其中，外部控制器（如MSP430F2132单片机）与ADG706的连接及其对ADG706输入通道的选择与控制均为常规技术，如专利CN200920251213.6《多通道光功率计》一文中介绍了单片机与ADG706的连接及其对ADG706的通道的选择与控制。 Among them, the connection between the external controller (such as MSP430F2132 single-chip microcomputer) and ADG706 and the selection and control of the input channel of ADG706 are conventional technologies, such as the patent CN200920251213.6 "multi-channel optical power meter" The connection between the single-chip microcomputer and ADG706 is introduced And the selection and control of the channel of ADG706.
本实用新型的有益效果是：此太阳跟踪传感器结构简单、易于实现，感光范围大，对太阳光强分辨率高，跟踪精度高，能从东西和南北2个方向同时检测太阳光线。 The beneficial effects of the utility model are: the sun tracking sensor has a simple structure, is easy to implement, has a large photosensitive range, high resolution to the sunlight intensity, high tracking precision, and can simultaneously detect the sun rays from east-west and north-south directions.
