Electronic delay-controlled detonator circuit and test method

Abstract

The invention provides an electronic delay-controlled detonator circuit and a test method. The electronic delay-controlled detonator circuit comprises a detonator, a delay control circuit, a switchingcontrol circuit, a double-capacitor charging circuit, a first test point, a second test point, a first detonating connection point and a second detonating connection point, wherein the first detonating connection point and the second detonating connection point are detonating connection points for the detonator, and the first test point and the second test point are test points for the detonator;the double-capacitor charging circuit comprises a first charging capacitor and a second charging capacitor, and the capacitance values of the first charging capacitor and the second charging capacitor are same; the positive pole of the first charging capacitor and the positive pole of the second charging capacitor are connected with each other and are both connected with the positive pole of a power source; and the negative pole of the first charging capacitor and the negative pole of the second charging capacitor are connected with each other and are both connected with the negative pole ofthe power source. The electronic delay-controlled detonator circuit increases the quantity of electric charge stored in the capacitors without increasing the complexity of a circuit design, thereby greatly reducing the circuit manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of detonators, in particular to an electronic delay control detonator circuit and a testing method. Background technique [0002] Due to the particularity of the working site of the electronic detonator and the complexity of the site, its stability must be guaranteed, which has high requirements for the stability and reliability of the electronic detonator device system, and it is often necessary to repeatedly test carefully before working on the blasting site. The existing nondestructive testing theory is immature, and it is impossible to realize fully automatic nondestructive testing in the true sense. How to design the interface of the electronic detonator for nondestructive testing is particularly important. Traditional electronic detonators often use a single capacitor as a charging and discharging circuit, which has certain limitations. Contents of the invention [0003] The aim of the present inven...
