Abstract

The invention relates to the technical field of circuits, and discloses a high-low-temperature-resistant communication circuit for an electronic detonator. The high-low-temperature-resistant communication circuit comprises a fuse F1, a resistor R1, a high-speed switching diode D1, a resistor R2, a resistor R3, a single-chip microcomputer MCU, a resistor R4, a triode Q1, a resistor R5, a diode D2,a diode D3 and a resistor R6. The high-low-temperature-resistant communication circuit for the electronic detonator has the advantages of being capable of realizing normal communication of the electronic detonator in a high-temperature or low-temperature environment, simple in structure and easy to realize.

Description

technical field [0001] The invention relates to the technical field of circuits, in particular to a high and low temperature resistant communication circuit and an electronic detonator for an electronic detonator. Background technique [0002] Electronic detonators, also known as digital electronic detonators, digital detonators or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. [0003] The working environment of electronic detonators is relatively harsh. According to the temperature shock resistance performance requirements of "WJ 9085-2015 Industrial Digital Electronic Detonators": Electronic detonators are kept at -40°C for 3 hours, at 80°C for 3 hours, and the temperature conversion time is 20s to 30s. Cycle 3 times , Keep it at room temperature for 1 hour after taking it out, and the electronic detonator should be able to detonate normally. [0004] However, most of the existing e...
