Problems solved by technology

[0005] There are mainly three kinds of instruments for measuring sunshine hours, which are dark cylinder type sunshine meter, focusing type sunshine meter and photoelectric sunshine meter. These sunshine measuring instruments are not suitable for measuring the sunshine hours, let alone the actual sunshine hours. According to the search, there is no instrument for measuring the sunshine hours at present, and it is particularly urgent and necessary to research and develop methods and devices for measuring the actual sunshine hours of buildings.

Embodiment Construction

[0011] As shown in Figure 1, the polar coordinate servo positioning pan / tilt is installed on the surveying and mapping bracket 4, and the laser range finder 1, the controller 3, the portable computer 5, and the portable printer 6 are connected to the polar coordinate servo positioning pan / tilt 2. First, time sampling is carried out at intervals of 5 minutes for a certain date from sun rise to sun set, and the time is sampled by a portable computer 5 . Carry out time sampling according to the interval of 5 minutes from the sun rising to the sun setting on a certain date, utilize portable computer 5 to calculate the altitude angle and azimuth angle of the sun at the sampling moment, and convert the altitude angle and azimuth angle into the stepper motor The driving signal is sent to the controller 3, so that the controller drives the polar coordinate servo positioning pan / tilt 2, so that the laser rangefinder installed on the arm of the automatic positioning pan / tilt can point to...

Abstract

A sun position simulation based method for quantitatively measuring sunlight time, includes that: performing time sampling according to a certain time interval from sunrise to sun fall, calculating altitude angle and azimuthal angle of sampling time using portable computers, pointing in time to the position of sun at sampling time with a laser distance measuring instrument, determining whether the sunlight is sheltered by measuring barrier distance, thereby measuring accurately the sunlight time of buildings. The invention is superior in quantitatively measuring year actual sunlight time of the present house or building, and performing all-weather measurement.

Description

technical field [0001] The invention relates to a fast annual sunshine hours quantitative measurement method based on sun position simulation. Background technique [0002] The phenomenon in which sunlight directly hits the surface of an object is called insolation. The phenomenon that sunlight directly irradiates the building lot, the outer structure surface of the building and the interior of the room is called building sunlight. Architectural sunshine is mainly to study the effect of direct solar radiation on buildings and the requirements of buildings for sunshine. [0003] Due to sunlight, various photobiological reactions of animals and plants are caused, thus promoting the metabolism of biological organisms. Ultraviolet rays contained in sunlight can prevent and treat some diseases, such as colds, bronchitis, tonsillitis and rickets. Therefore, it is of great hygienic significance for buildings to have suitable sunshine; secondly, sunlight c...
