The invention provides a plateau mountain PLP installation height determination method and system. The plateau mountain PLP installation height determination method comprises the steps of obtaining a plurality of preset installation positions of a plurality of PLP lightning protection devices; constructing a plurality of installation areas corresponding to the plurality of PLP lightning protection devices according to the plurality of installation positions; acquiring historical lightning stroke data corresponding to the current installation area; determining a first protection device with the farthest horizontal distance from the first PLP lightning protection devices corresponding to the area in the current installation area; obtaining topographic data and target equipment height of the first protection equipment, and a target horizontal distance between the first protection equipment and the first PLP lightning protection device; and according to the historical lightning stroke data, the topographic data, the target equipment height and the target horizontal distance, the installation height of the first PLP lightning protection device is calculated based on a rolling ball method. The precision of the PLP installation height can be improved, and the method is suitable for the special terrain and the lightning stroke risk of the plateau mountain land.

The present application relates to the technical field of science popularization exhibits, and specifically relates to a timing method based on a rolling ball clock. The present application comprises timing guide rails in an inclined distribution, which are arranged in at least two layers in sequence from top to bottom. Each of the timing guide rails is provided with timing grooves and advanced guide grooves. The timing grooves are used to store a plurality of timing balls to represent the number of time units of the current layer. The rolling ball clock further comprises a conveying assembly for continuously supplying timing balls to the timing grooves of the uppermost layer with a time difference. The timing method of the rolling ball clock comprises the following steps: continuously conveying timing balls to the first layer of the timing grooves of the uppermost layer of the timing guide rails by the conveying assembly, and each conveyed timing ball represents an increase of one time unit of the first layer of the timing grooves. The present application has a reasonable structure and precise and reliable action, thereby effectively stimulating the public interest in science and ultimately achieving the effect of enlightening science.

The application provides a smart lightning rod arrangement visualization design method based on a rolling ball method, comprising the following steps: S1: a building contour drawing step; S2: a lightning rod arrangement step, based on the rolling ball method, using a fillPolygonWithCircles algorithm to automatically generate lightning rod center points; and S3: a coverage verification and downlead generation step. The application aims to overcome the defects of the prior art and provide a real-time interactive visualization lightning rod arrangement system, which ensures 100% coverage of the building by allowing the user to hand draw the building contour, automatically calculating the rolling ball method protection area, and optimizing the lightning rod position; meanwhile, the downlead path and material list are generated, the design cycle is shortened to the minute level, the accuracy and practicability of the lightning protection scheme are improved, and the engineering error rate is reduced.

The present application relates to the technical field of science popularization exhibits, in particular to a rolling ball clock. The present application comprises a timing guide rail in inclined distribution, which is arranged in at least two layers from top to bottom. Each layer of the timing guide rail is provided with a timing groove and a next guide groove. The timing groove is used to store a plurality of timing balls to represent the number of time units of the current layer. When the timing groove of the current layer is full, the timing balls are deviated to the next guide groove and transported to the timing groove of the next layer through the next channel. Then, the timing groove of the current layer releases all the timing balls. The rolling ball clock further comprises a conveying assembly for continuously supplying timing balls to the timing groove of the uppermost layer with the same time difference. The present application has a reasonable structure and precise and reliable action, so as to effectively stimulate the public interest in science and finally achieve the effect of enlightening science.
