Intelligent control circuit with cipher timing detonator

Abstract

The invention relates to an intelligent password timing blaster control circuit which comprises a double CPU control circuit, a hardware watchdog reset circuit, a charge control circuit, a percussion control circuit, and the like. The double CPU control circuit comprises two CPUs, which are communicated with each other through a serial interface. The hardware watchdog reset circuit, a high voltage sampling circuit, a battery power measurement circuit and a datum voltage generation circuit are connected with the first CPU; and a control terminal of the charge control circuit is connected with the first CPU, and a charge control terminal thereof is connected with the second CPU. The percussion control circuit comprises a percussion machine connected with the first CPU. The invention improves the reliability of the circuit through the respective controls of the two CPUs. When either CPU can not work normally, blasting can not be conducted, thereby achieving high reliability and high safety. The battery power, the charge voltage and the datum voltage can be accurately measured. When any link can not meet the requirements, the blasting can not be conducted, thereby preventing the occurrence of mis-explosion.

Description

technical field [0001] The invention relates to a control circuit of a detonator used in rock blasting operations, in particular to an intelligent timing detonator control circuit with password which has high reliability and can be intelligently timed. Background technique [0002] Nonel detonators are used in mining, mountain blasting and other construction projects. At present, the fuse detonation method is mostly used, but this method needs to arrange a long fuse, and the cost of each detonation is high. And it is more troublesome to take in and out the line. At the same time, this method is not safe. At present, domestic detonators are vigorously promoting a safer detonator detonation method, but the current detonators cannot be accurately timed, and when accidents occur in the detonators or other parts, the detonators cannot detonate. At this time, it is not sure whether the detonator can still be detonated, so it cannot be approached for inspection for a long time. T...

Problems solved by technology

[0002] Nonel detonators are used in mining, mountain blasting and other construction projects. At present, the fuse detonation method is mostly used, but this method needs to arrange a long fuse, and the cost of each detonation is high. And it is more troublesome to take in and out the line

At the same time, this method is not safe

At present, the relatively safe detonator detonation method is being vigorously promoted in China, but the current detonator cannot be accurately timed, and when the detonator or other components have an accident, the detonator cannot detonate

At this time, it is not sure whether the detonator can still be detonated, so it cannot be approached for inspection for a long time. This kind of detonation with a long delay can easily cause casualties, and such incidents are also common in newspapers.
