AI Technical Summary

Technical Problem

When cleaning a large number of heliostats in the full mirror field, the navigation labels in the prior art are easily affected by strong light and the data fails, resulting in inaccurate coordinate data of the cleaning equipment or failed positioning, which increases the amount of manual labor and power station maintenance costs.

Method used

By setting a marking device on the heliostat at the edge of each circle in the entire mirror field, and using an ultrasonic sensor and ranging module to collect data, determine the relative position relationship between the heliostat cleaning device and the current heliostat mirror surface, and then determine the target steering angle to achieve automatic travel and cleaning.

Benefits of technology

It reduces the amount of manual labor and power station maintenance costs, improves the degree of automation and accuracy of heliostat cleaning equipment, and reduces the need for real-time data processing and storage capabilities.

Abstract

The invention discloses a heliostat cleaning equipment control method, device and equipment, a medium and a product, and relates to the technical field of solar heat utilization, and the method comprises the following steps: controlling heliostat cleaning equipment to start to advance from a cleaning channel on the innermost side of a full mirror field, and circularly executing navigation operation until the operation is finished, the navigation operation comprises the following steps: determining a relative position relationship based on an obtained first numerical value and an obtained second numerical value; determining a target steering angle of the heliostat cleaning equipment based on the current mark state and / or the relative position relation; in the process that the heliostat cleaning equipment moves based on the target steering angle, whether the heliostat cleaning equipment is located on the outermost cleaning channel currently or not is judged; if not, controlling to enter the next navigation operation; if yes and when the advancing ring switching state of the heliostat cleaning equipment is' advancing ring switching completion ', not entering the next navigation operation. The heliostat cleaning equipment is controlled to automatically advance, and the purposes of reducing the manual labor amount and saving the maintenance cost of a power station are achieved.
