Embodiment Construction

[0027] 1. Install high precision positioning equipment. Intelligent vehicle-mounted terminal (7) is installed on the drilling rig, and the high-precision GPS device A point (1) and the high-precision GPS device B point (2) can be installed on the drilling rig at any position except the drill pipe O point (3). Choose an easy-to-install location with less vibration, but point A (1) and point B (2) cannot overlap; the installation of the electronic compass (4) must be parallel to the drilling rig platform (6), and the direction should be in line with the body direction of the drilling rig Consistent, this case is installed in the rig cab (5); A point (1), B point (2) and electronic compass (4) are connected to the intelligent vehicle terminal (7) by cables.

[0028] 2. Initialize point A (1), point B (2) and electronic compass (4). First put the drilling rig in a stable horizontal state, record the coordinate values ​​taken out of the equipment at point A (1) and point B (2), an...

Abstract

The invention discloses a method for achieving real-time high-precision location of a strip mine driller drilling rod, and relates to the field of electronics technology and high-precision GPS location application. The real-time high-precision location of the drilling rod when a strip mine driller works is achieved by utilizing two high-precision GPS devices and an electronic compass apparatus, which are mounted on the driller, combining with a vehicular terminal, initializing apparatuses and then operating a three-dimensional space coordinate transformation algorithm and a two-dimensional space coordinate transformation algorithm. The method for achieving the achieving real-time high-precision location of the strip mine driller drilling rod changes the traditional manual by-experience hole alignment production mode, and solves the problems that the precision cannot be ensured and the service lives of apparatuses are short by the existing method. The hole drilling precision of the driller is largely improved, and the blasting effect and the automation level of mining are improved.

Description

technical field [0001] This case involves the fields of electronic technology and high-precision GPS positioning, and specifically involves a set of methods for realizing high-precision positioning of drilling rigs in open-pit mines. Background technique [0002] The traditional mode of piercing and blasting operations in open-pit mines is that the drilling personnel place piles of stones in the blast area where the drilling rig needs to be drilled, and the drill driver drills the pile of stones based on experience. The drilling position is very inaccurate, which affects the blasting effect. With the continuous development of mine digitization, the demand for refined management of mining production continues to increase, and the accuracy requirements for drilling rig drilling in the blasting process are also further stringent. [0003] At present, there are two methods of using GPS to locate the drill pipe, one of which is to install a high-precision GPS positioning device o...
