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 c

Embodiment Construction

[0021] specific implementation

[0022] Use the general GPS OEM board to receive satellite signals, carry out three-dimensional positioning and timing of the explosion point, calibrate the high-precision satellite timing signal to the high-precision clock in the control unit and the receiving unit, and synchronize them; use the embedded 80×86 computer board as the master When the controller is working, the main controller controls the timing and logic of the synchronous explosion control system after inputting the measuring line number and shot point number with the keyboard. When the "AND" relationship is formed among the measuring line number, the gun number and the agreed time, the main controller ensures safe and synchronous detonation as required; in this system, a newly added 24-bit A / D data acquisition board has Large-capacity memory is used to directly record the relevant data of the explosion point that the user needs to record, and solve the problem of inaccurate sig...

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 ...
