Problems solved by technology

Although the map matching technology based on weighted functions is simple to implement, the empirical values ​​of multiple parameters such as the radius of the search area and each weighted value in the weighted function need to be determined through a large amount of measured data.

Embodiment Construction

[0038] figure 1 , figure 2 As shown, it is a fast matching method of crane track map, which includes the following steps:

[0039] The first step is to convert the transmission line into a line according to the number of the tower in a transmission line, and connect it with a straight line according to the number of the tower, and each straight line can be equivalent to a road, where the longitude, latitude, and number of the tower in each transmission line , the distance from the front and rear towers, and the direction of the corner are all obtained from the database;

[0040] The second step is to divide the towers and roads into areas, and according to the continuity of vehicle movement, the entire road network is divided into several grids from left to right and top to bottom with a predetermined length as the step size, and divided into m× n areas; where m and n represent the number of rows and columns of the divided area, and each area has a unique index number corre...

Abstract

The invention discloses a fast matching method of a crane track map. Information uploaded through a GPS positioning device installed on a crane mainly comprises the information such as crane latitude and longitude, speed, direction, time and crane working condition. The working condition is measured through an acceleration sensor installed on a gib arm of the crane and comprises four states of traveling, waiting, operating and stopping. According to the fast matching method of the crane track map, an electric transmission line is equivalent to a road through a broken line, database storing is facilitated, a calculation formula of the vertical distance between a crane real-time location and a road to be matched and the distance between the crane real-time location and an electric transmission line is simplified by combining reality, and the calculation formula is equivalent to a calculation formula of the distance d from a GPS locating point to the road to be matched. The algorithm flow can be further simplified.

Description

technical field [0001] The invention relates to a method for quickly matching crane track maps, belonging to the technical field of electric power systems. Background technique [0002] At present, how to prevent high-voltage transmission lines from being damaged or touched by external forces, especially large-scale mechanical construction equipment such as cranes, has always been a major issue for the transmission line operation and maintenance department of power supply companies. In the transmission line protection area, accidents where vehicles, especially cranes, touch transmission lines often occur. Taking the urban area of ​​Suzhou as an example, the power supply company has dozens of tripping incidents of 110 kV and above transmission lines caused by cranes and other large construction machinery every year, causing direct economic losses of several million yuan, and may also cause economic losses to power customers. millions of dollars. [0003] Installing a GPS po...
