Problems solved by technology

[0003] In the prior art, it is always difficult for sun tracking sensors to combine "high sensitivity" and "two-coordinate sensing". They are often combined with two one-coordinate sensors, or a sensor without anti-interference The low-sensitivity two-coordinate sensor of the shading device often causes unstable work due to the influence of scattered light from the surrounding environment in the application
This brings certain difficulties to installation and debugging, and also introduces unnecessary errors to the precise operation of the equipment. Therefore, it is very necessary to design a two-coordinate high-sensitivity sun tracking sensor that can resist interference

Embodiment Construction

[0021] The structure of one of the sensor embodiments is shown in Figure 1

[0022] The principle of high sensitivity of this sensor is as follows:

[0023] As shown in Figure 1, it is the one-dimensional working principle of the sensor of the present invention: the rectangular reflective column is at the top of the pyramid, and has a certain height, which can be 0.5 to 10 times the height of the pyramid itself. The bigger it is, when the sun rotates through a unit angle, the shading shadow of its backlight surface is also longer, and it is easier to cover the unit photosensitive element (such as image 3 As shown in the triangle net shadow on the left side of the rectangular reflective column), the influence on the output electrical signal is greater. In other words: the longer the rectangular reflective column, the smaller the sun deflection angle required for its shadow to cover a unit photosensitive element, and the more sensitive the sensor will be. This is one of the r...

Abstract

The invention relates to a dual-coordinate high-precision sun tracing sensor, which belongs to the field of solar energy application and is used for sensing a real time dynamic tracing device of solar azimuth of a solar energy heat concentrating and collecting system and a solar energy photovoltaic system. The dual-coordinate high-precision sun tracing sensor comprises two pairs of photosensitive apparatuses 1 with same parameters, a rectangular reflecting column 2 with reflector surfaces on four sides, a pyramid platform 3, a shade tube 4 and a base 5; the two pairs of photosensitive apparatuses 1 are respectively mounted on four bevels of the pyramid table, and the rectangular reflecting column 2 is vertically arranged on the top of the pyramid table 3. The mirror reflective panels on the four sides and the four bevels of the pyramid table are distributed oppositely and respectively one by one. The shade tube 4 is connected with the base 5 and located at the bottom of the sensor. A precise three-dimensional sun tracing system can be formed by mounting the sensor on the light receiving surface of the solar energy collector through a group of signal analyzing system as well as an apparatus driving system and a mechanism driving system which follow up the solar energy collector.

Description

Technical field [0001] The invention is a two-coordinate high-precision sun tracking sensor, which belongs to the application field of solar energy and is used for real-time dynamic tracking of the sun orientation of solar heat collection and heat collection systems and solar photovoltaic power generation systems, especially solar energy concentrating collection equipment. sensor. Background technique [0002] Today, when the global fossil energy is about to be exhausted, the in-depth development and application of solar energy has attracted people's attention. But in the past, people only developed some basic products in the field of low-temperature application of solar energy, such as solar water heaters, solar photovoltaic cells and other products that do not have high requirements for tracking or basically do not need tracking. Mature, so tracking technology is not widely used. Today, people have gone deep into the research and development of solar energy, high-tempera...
