Electronic detonator control chip and processing method for correctly restoring host computer communication signal

Abstract

The invention discloses an electronic detonator control chip and a processing method for correctly restoring a host computer communication signal. The electronic detonator control chip comprises a rectifying circuit, a reset circuit, a power supply circuit, a signal preprocessing circuit, a signal conversion circuit, a current feedback circuit, a digital logic processing circuit, an oscillator clock circuit, an NV (Non-Volatile) memory circuit, an energy-saving capacitor charge control circuit and a detonator ignition driving circuit. According to the electronic detonator control chip and the processing method, disclosed by the invention, the non-polarity connection of a communication signal of an electronic detonator is realized, and the problems that wrong wire connection is caused by a wiring worker, and thus a host computer command cannot be recognized by the electronic detonator control chip can be avoided; meanwhile, a host computer signal is taken by the electronic detonator control chip before the rectifying circuit, and the negative influence of a rectifying element on signals in the rectifying circuit can be avoided.

Description

technical field [0001] The invention relates to the technical field of electronic detonators, in particular to an electronic detonator control chip and a processing method for correctly restoring communication signals of a host computer. Background technique [0002] Electronic detonators, also known as digital electronic detonators or digital smart detonators, are actually ordinary prompt detonators with external electronic control circuits. Its essence is to use a control module containing a microelectronic chip to drive the ignition head. The module replaces the delay charge in the ordinary delay electric detonator, greatly improving the delay accuracy, and its detonation ability is the same as that of the traditional delay charge detonator. Whether to control detonation and detonation delay are its two basic functions. Generally speaking, the electronic detonator is controlled by a dedicated host that communicates with it. The output of the host is connected in parallel...
