Problems solved by technology

[0006] The existing measurement and adjustment technology relies on manual operation throughout the entire process. Due to the large area of ​​the concentrator, the area of ​​the standard arc plate matched with it is also quite large. Adjustment technology has high labor intensity, low detection accuracy, and low detection and adjustment efficiency

Abstract

The invention discloses a method for detecting and regulating surface types of a solar heat-collection condenser, belonging to the field of detection and regulation of the surface types of condensers. The detection method comprises the following steps of: setting test points on the solar heat-collection condenser to be detected; acquiring image data of the test points through camera acquisition equipment; transmitting the image data to a data processing terminal; and processing the image data by using the data processing terminal, and thus acquiring position error data of the test points and the corresponding points on standard surface types. According to the method, the surface types of the solar heat-collection condenser are detected by a digital photogrammetry method, standard arc plates are not required to be manufactured and used, manual measurement and detection are not required, a great number of manpower resources are saved, and the measuring time is shortened. Meanwhile, error data acquired by the digital photogrammetry are accurate and reliable, the measurement accuracy is high, condenser reflectors can be quantitatively regulated in a targeted manner, and the efficiency of detection and regulation is improved.

Description

technical field [0001] The invention relates to the field of detecting and adjusting the surface shape of a concentrator, in particular to a method for quickly detecting and adjusting the surface shape of a solar heat collector. Background technique [0002] In recent years, with the depletion of conventional energy and the continuous strengthening of people's awareness of environmental protection, clean and environmentally friendly new energy, especially solar energy, has begun to be continuously developed and utilized. At present, the utilization temperature of solar energy is mainly increased through the concentrating of solar thermal concentrators, so that solar energy can be applied in different fields. High-temperature solar energy can be applied in the field of solar power generation; medium-temperature solar energy can be applied in industrial fields, especially in heat extraction in food processing, plastic processing, glass processing, chemical industry, paper indu...
