Problems solved by technology

[0007] In order to overcome the disadvantages of high cost and poor stability of the prior art, the present invention provides a tracking and aiming control method and device for a heliostat. The control method and its device adopt the combination of low-cost high-precision aiming sensor, sun position recognition tracking sensor and three-point-one-line tracking bracket structure aiming method, so that the reflected light point of the (mirror) heliostat is on the designated target. , The reality that the sun rises to the sun sets in various places on the earth throughout the year, and the reflected light point does not move

Embodiment Construction

[0019] Hereinafter, a heliostat tracking and aiming control method and device thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings. figure 1Shown is the tracking and aiming control method of the heliostat and its device system of the embodiment of the present invention, which includes a heat collector 2 on the heat collector tower 9, and the heat collector 2 receives the reflective surface of the heliostat 4. For the reflected light beam, the aiming sensor 7 is fixed on the aiming sensor bracket 6 by the adjuster 15 of the aiming sensor. Between them, the reflective surface of the heliostat, the aiming sensor 7, and the heat collector 2 are arranged in a three-point line at 180 degrees, and photoelectric sensors 10, 11, 12, and 13 are respectively installed at four positions at one end of the beam splitter 14 to split the light. The other end of the device is connected with the shutter E, and when the reflect...

Abstract

The invention discloses a tracking and aiming control method and device for a heliostat. The traditional calculation method and the traditional computer control system are not adopted, while a new way is established. According to the tracking and aiming control method and device, a low-cost high-precision aiming sensor, a sun position recognition and tracking sensor and a three-point line tracking support aiming method are combined; accordingly, the heliostat is allowed to recognize the sun position and track the sun, and the light reflected to a specified target is fixed; the fact that a reflecting point of the heliostat, namely the heliostat, is permanently fixed at the specified target everywhere on earth for all seasons while the sun moves; the heliostat control method and device is implemented all by sensors. The system and structure of computers, software, programs, equations, longitude and latitude, linked control structure, laser aiming control, CCD aiming control, PLC control, large curved mirror reflection, and servo motor drive is not considered; stability and wind resistance are increased by several times; system cost and operation and maintenance cost are reduced by tens of times.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization and solar thermal power generation, in particular to the technical field of a solar tower thermal power generation heliostat control system, a method for tracking and aiming control of a heliostat and a device thereof. Background technique [0002] To solve the problem of air pollution on the earth, the energy of the sun must be used to provide the power needed by human beings. The industrialized utilization of solar energy must be based on large-scale lighting and large-scale concentration. At home and abroad, large-scale tracking and concentration is still an industry Due to the technical short board, there is still no suitable technology and product supply, so that the idea of ​​large-scale industrialization and commercial utilization of solar energy has not been realized, which has seriously restricted the development and utilization of solar tower thermal power generation, and h...
