Abstract

The invention provides an interlocked digital display remote control exploder, which can accurately measure the resistance value of a detonator to be exploded. The interlocked digital display remote control exploder comprises a microcontroller for operating and controlling, a light-emitting diode (LED) display which is connected with the output port of the microcomputer and a relay J3 for controlling, and is characterized by also comprising a reed switch, a constant current source and a detonator resistance measuring loop, wherein the reed switch is connected in series with the coil of the relay J3; the output port of the constant current source is connected in series with a normally open point of the relay J3 and connected to the detonator resistance measuring loop; the detonator resistance measuring loop is electrically connected with an analogue / digital (A / D) converter; and the output end of the A / D converter is connected with the input port of the microcontroller. The interlocked digital display remote control exploder is provided with the detonator resistance measuring loop and the constant current source, so that fault judgment, impedance measurement and individual electric detonator resistance value measurement are realized.

Description

technical field [0001] The invention relates to an interlocking digital display remote control detonator, more specifically, an interlocking digital display remote control detonator capable of accurately measuring the resistance value of a detonator to be blasted. Background technique [0002] The vast majority of network detection detonators are to add two terminals to the detonator, and connect the blasting bus to the two terminals. One method is to use the light-emitting diode to light up or extinguish to judge the on-off of the blasting network, but When the blasting bus is short-circuited, the LED is still on; when the blasting bus is disconnected, the LED is not lit, and the detonator is charged and detonated. This method is unscientific; the other is to use a digital meter to display the network. The connection state of the circuit resistance (open circuit, short circuit) and the total resistance value of the network detonator. These two types of detonators are not l...
