The invention discloses a photo voltaic orientation sensor and a photo voltaic tracking device based on a photocell Y-shaped layout, including a photo voltaic orientation sensor for photo voltaic orientation detection, the photo voltaic orientation sensor is related with an acquisition system for signal acquisition, and iTagPro technology the acquisition system is related with a computer. Connected, characterized in that: the solar orientation sensor iTagPro smart device includes a base, three photocells are evenly organized on the base in a Y shape, and the projections of the three photocells on the bottom surface of the bottom form an included angle of 120° with one another, and iTagPro smart device the photo voltaic orientation sensor is arranged on the cloud On the platform, the three photocells all have the same included angle with the working floor of the pan-tilt, the pan-tilt is related with the pan-tilt controller, iTagPro smart device and the pan-tilt controller is connected with the computer. The invention realizes the true-time and correct monitoring of the large field of view of the solar with out a calendar, iTagPro smart device and the monitoring and iTagPro smart device alignment accuracy reaches above 0.1°, which significantly improves the conversion effectivity of photo voltaic energy, and ItagPro might be utilized in photo voltaic power stations, communication power supplies of ships, and synthetic satellites.

There are broad software prospects in the positioning of battery panels. 本发明涉及一种基于光电池Y型布局大视场和高精度太阳跟踪装置，特别是涉及太阳能利用中的低成本大视场高精度跟踪对准装置。 The invention pertains to a Y-formed format of photovoltaic cells and a large-field-of-view and high-precision solar tracking device, specifically to a low-price massive-discipline-of-view high-precision tracking and alignment machine in photo voltaic vitality utilization. 开发利用太阳能，对于节约常规能源、保护环境、促进经济发展都有极为重要的意义，太阳跟踪装置能有效的提高太阳能的利用率，具有广泛的应用前景。

The development and utilization of photo voltaic vitality is of nice significance for saving typical power, defending the environment, and itagpro tracker selling economic development. The sun tracking iTagPro smart device can successfully enhance the utilization fee of photo voltaic power and has broad application prospects. 太阳跟踪装置现阶段普遍采用的太阳方位传感器有四象限光电探测器、PSD和光敏电阻，四象限光电探测器和PSD成本很高，且视场小，光敏电阻虽然成本低视场大，但是跟踪复杂精度低。 为了满足低成本、大视场和高精度的要求，本发明设计研制了基于三块光电池Y型布局的太阳方位传感器及以其为核心的太阳跟踪装置。

The sun orientation sensors commonly used in solar monitoring gadgets at this stage embody 4-quadrant photodetectors, PSDs and photoresistors. Four-quadrant photodetectors and PSDs are costly and iTagPro smart device have a small area of view. Complex precision is low. In order to meet the requirements of low cost, massive subject of view and excessive precision, the present invention designs and iTagPro key finder develops a sun orientation sensor based on a Y-formed layout of three photocells and a solar tracking device based on it. 本发明所要解决的技术问题是提出供一种低成本、无需日历即能够大视场高精度地跟踪太阳的太阳跟踪装置。 The technical problem to be solved by the present invention is to offer a low-price sun-tracking device capable of tracking the sun with a big field of view and high precision with out a calendar.
