Mine exploder with fingerprint detection function

Abstract

The invention provides a mine exploder with a fingerprint detection function. The mine exploder comprises a storage battery, a multi-layer millisecond switch, a transformer, an electric storage capacitor C7, a microcontroller, a four-bit nixie tube, a blasting bus positive electrode and a blasting bus negative electrode. The mine exploder with the fingerprint detection function is characterized by comprising a fingerprint detection module, a light-emitting diode D24, a light-emitting diode D25 and a light-emitting diode D26, the fingerprint detection module is used for recognizing fingerprint information of a gas watchman, a job foreman and a blasting person, and the light-emitting diode D24, the light-emitting diode D25 and the light-emitting diode D26 are used for indicating whether the right fingerprint information is detected. According to the mine exploder, the fingerprint information of the gas watchman, the job foreman and the blasting person needs to be verified before detonation, if the fingerprint information passes the verification, the corresponding light-emitting diodes flicker, only the fingerprint information of all the persons passes the verification, the exploder can be used for conducting detonation work, and the blasting safety is effectively ensured.

Description

technical field [0001] The present invention relates to a mining detonator with a fingerprint detection function, more specifically, to a mining detonator with a fingerprint detection function which needs to verify the fingerprint information of tile inspectors, team leaders and blasters before charging. Use a blaster. Background technique [0002] As a tool for detonating series-connected electric detonators, the mine detonator is used in the particularity of coal mine operations, and has strict requirements on the intrinsic safety and explosion-proof characteristics of the detonator. The specification (capacity) of the detonator is represented by the rated number of detonators, and its series are: 10 rounds, 25 rounds, 50 rounds, 100 rounds, 150 rounds, 200 rounds, etc. The reason why it is necessary to design the model of the detonator according to the quantity of detonated electric detonators is that the ignition impulses required by different quantities of electric det...

AI Technical Summary

Problems solved by technology

The performance of the storage capacitor is that the charging voltage of the capacitor is different. If the voltage at both ends of the capacitor is too high, it is easy to cause a spark accident before detonation, which will have an adverse effect on safety; "Phenomenon, for the unignited electric detonators scattered in the coal mine roadway, there is undoubtedly a huge potential safety hazard
