Four-channel constant-current-source delay explosion starter

Abstract

The invention discloses a four-channel constant-current-source delay explosion starter. The four-channel constant-current-source delay explosion starter comprises a shell, wherein a control panel is arranged in the shell; a plurality of positioning pin holes and mounting holes are formed in the shell; a display screen is arranged on one side of the control panel; a power button is arranged on oneside of the display screen; an enabling button is arranged at the bottom of the power button; a menu button is arranged at the bottom of the enabling button; a setting button is arranged at the bottomof the menu button; an indication light is correspondingly arranged on one side of each of the power button, the enabling button, the menu button and the setting button; a power interface is formed in the bottom of the display screen; a triggering interface is formed in one side of the power interface; a plurality of load channels are formed in one side of the triggering interface. A circuit board timing module is arranged through the menu button; ignition channels are isolated from each other; the isolation manner is achieved by optical-coupler isolation; the optical-coupler isolation is achieved by a 20ns high-frequency response control circuit; the ignition relaying setting is achieved by a delaying control circuit. The four-channel constant-current-source delay explosion starter is applied to operation conditions of relayed ignition of pre-tightening of safety belts, gas gunpowder generators, safety gas bags and the like.

Description

technical field [0001] The invention relates to the technical field of detonators, in particular to a four-channel constant current source delay detonator. Background technique [0002] The time delay of the existing detonator is unstable, and the delay range is not accurate enough, which brings great inconvenience to the use, and there are few ignition channels, and each ignition channel is related, which brings inconvenience to the work of the detonator , if not equipped with a separate power supply, it is easy to affect the work of other parts, thereby affecting the work of the whole device, and the existing detonator may be falsely detonated, which brings great inconvenience to the user. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a four-channel constant current source delay detonator. The four load channels provided are independent isolation ignition channels, which are ...
