Intelligent system for contolling synchronous explosion according to time transmitted from GPS

Abstract

The system includes computer, 24 bits A / D acquisition board, high voltage charge / discharge control board as well as time control, timer, display board and control circuit. The said each part is connected through control wiring. The control signal is stable, not affected from influence of topography, interference and weather basically. The information at explosion point is received and recorded at explosion point so as to raise reliability. The said information can be processed in real time in order to carry out quality control effectively. General-purpose GPS makes design and manufacture easier. The invention is applicable to oil, geological and coal exploration. 3D positioning of explosion point is available in the invention, and synchronous accuracy is better than 0.01% so as to extende application area.

Description

Technical field [0001] The invention relates to a GPS timing intelligent synchronous explosion control system used in petroleum exploration, geological exploration, coal field exploration and engineering blasting for high-precision synchronous blasting, synchronization accuracy <0.1%, and synchronous distance hemisphere. Background technique [0002] It is a general way of modern explosive technology to detonate the explosive package by electrifying the electric detonator. The system that controls the energization to the electric detonator is called the explosion control system, and the explosion control system that needs to record the explosion and receive information or synchronize several explosion initiation systems is called the synchronous explosion control system. The existing synchronous detonation detonation system consists of two parts; the detonation main control unit is composed of the recording system receiving information; the controlled unit is composed of ...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is 1. The synchronization time accuracy is affected by the delay of different radio stations; 2. The control distance is affected by the communication distance and communication quality of radio stations, and there are many factors that affect the communication distance and quality, especially weather, mountains and woods; 3. The information related to the explosion point returned to the control unit, such as; wellhead signal, verification synchronous explosion signal, etc., also needs to be transmitted back through the communication station, and its accuracy is often affected by the delay of the station or electromagnetic wave interference; 4, the price is expensive

Therefore, its professionalism is strong and the price is very expensive

[0005] In order to solve the communication problem of the synchronous detonation detonation system, foreign companies have increased the power of the communication station from 10 watts to 25 watts, which has a certain effect, but the battery consumption is greatly increased, the weight is greatly increased, and the cost is also increased.
