Problems solved by technology
However, the formula to obtain the precise angle is complicated, and the real-time calculation cost is high
The approximate formula MCU can complete the calculation but the accuracy is not high
It also needs to rely on the deep tube light sensor or other sensors to adjust, the cost is still high, and the control system of each mirror has different initial values of the coordinates of the geographical location, which is troublesome to operate, and if it is to rely on a terminal computer to control all mirrors, all mirrors stop working if there is a condition

The invention discloses a novel heliostat control method which utilizes a three-axis gyroscope to measure whether a heliostat is absolutely level or not. The control method comprises the following steps: when a single chip microcomputer controller on the three-axis gyroscope controls a stepping motor X and a stepping motor Y to enable that an A shaft of the heliostat rotates to a position when the heliostat is absolutely level, a command is sent to the single chip microcomputer controller to stop the stepping motor X and the stepping motor Y immediately if the heliostat is not level; calculated angle data required to rotate in each minute in one year is copied simultaneously in a data card for saving; the single chip microcomputer controller reads the data in the data card, enables the stepping motors to control a pitching angle and a self rotating angle of the heliostat to rotate an angle according to existing 'time-corresponding angle' saved in the data card and through a frequency converter to achieve the aim that the heliostat can reflect sunshine accurately. According to the novel heliostat control method, the requirements for mounting and an initial angle are lowered, the cost is low, and the operation is simple. Therefore, the heliostat control method is relatively economical and practical.
Description
technical field [0001] The invention relates to a heliostat, in particular to a novel heliostat control method. Background technique [0002] The so-called heliostats are the main part of collecting sunlight in tower power generation. According to the real-time position of the sun every day, the angle of each heliostat is adjusted by computer so that all heliostats reflect sunlight to the receiver. These heliostats The mirror tracks the sun minute by minute. The sunlight is reflected to the bull's-eye, and the heat collecting device gathers less and becomes more to generate electricity. [0003] For traditional heliostats, all the mirrors are connected to the terminal computer. The computer calculates the sun angle in real time according to the time, and at the same time calculates the azimuth and elevation angles of each mirror, and sends commands to control each mirror to follow the sun to keep running. Or each mirror contains an independent computing system that cal...
