GPS (global positioning system)-based dam concrete material tank collision monitoring and navigation positioning method

Abstract

The invention relates to a GPS (global positioning system)-based dam concrete material tank anti-collision monitoring and navigation positioning method. According to the method, a material tank collision monitoring algorithm based on time and space is designed according to the position of a material tank, running speed information and field obstacle information, which are monitored and acquired in a GPS in a real-time manner, and pre-warning judgment can be made against the potential collision probability of the material tank in the two aspects, namely the time and the space in the real-time manner; simultaneously, the invention provides two navigation positioning methods, namely the static method and the dynamic method for guiding a driver to perform high-efficient and correct operation on the concrete material tank, thereby providing a safe, reasonable and reliable navigation path for fast construction. By adopting the method, the occurrence of serious construction accidents of collision of equipment caused by human factors during the construction process can be effectively reduced.

Description

technical field [0001] The invention relates to a method for collision monitoring and navigation positioning, which belongs to the field of construction information technology, in particular to a GPS-based monitoring and early warning of the collision of the material tank of the cable machine in the dam concrete pouring, and on this basis, the running track of the material tank is carried out. The method of navigation and positioning. Background technique [0002] As a construction equipment widely used in dam construction, translational cable crane is mainly used for pouring and metal structure hoisting. Its high lifting height, large operation range, long working hours and high lifting efficiency play a very important role in the entire construction period of the dam. On the construction site, especially the pouring site of the dam body, the operation of the material tank of the cable crane will be affected by surrounding buildings, large equipment or other obstacles, and...

Problems solved by technology

However, there are some deficiencies in these anti-collision monitoring and early warning technologies: First, the existing technologies mostly use sensors and other monitoring equipment to monitor obstacles, and the accuracy of ranging from sensors is limited, and the ranging accuracy of more than ten meters is unreliable. For the material tank, a safety distance of more than ten meters is not enough; secondly, the operation of the cable machine material tank is dynamically changing in real time, and the existing monitoring and early warning technology is not combined with the operation status of the material tank itself, and the distance from the material tank is similar The object is not necessarily an obstacle that will collide with the tank; finally, it does not provide a safe and intuitive optimal running path for the driver and operator. In actual construction, due to the complexity of the construction site and the harshness of the natural environment, Operators cannot rely solely on the naked eye for construction operations

In summary, the main problem of the collision avoidance judgment system in large-scale construction is that the degree of informatization is not high enough, and there is no active and reliable guidance for construction
