Abstract

The invention discloses a signal receiving circuit of an electronic detonator, and belongs to the technical field of electronic detonators. The signal receiving circuit comprises a logical operation unit and two signal receiving accesses, the logical operation unit has two input ends and one output end, and the two signal receiving accesses are connected with the two input ends of the logical operation unit in a manner of one-to-one correspondence. Each signal receiving access comprises a Schmidt trigger with operating voltage of 2.5V-24V and a voltage converting unit used for converting inputlevel signals to reference level signals for output, and the Schmidt triggers, the voltage converting units and the logical operation unit are connected sequentially in the signal direction. The signal receiving circuit is simple in circuit structure, low in cost and power dissipation and high in reliability, can receive complex bus signals stably and correctly, and is compatible with signal transmission of low-voltage and high-voltage communication and suitable for communication between controllers and electronic detonators in processes such as production, detection and use.

Description

technical field [0001] The invention relates to the technical field of electronic detonators and pyrotechnics, in particular to an electronic detonator signal receiving circuit. Background technique [0002] The electronic detonator produced by the combination of integrated circuit technology and pyrotechnics technology is an inevitable development trend of industrial detonators. Electronic detonators use integrated circuits to replace the delayed gunpowder in industrial detonators, and use integrated circuits to achieve high-precision delay, safety control and reliable detonation. [0003] The electronic detonator is mainly composed of a circuit board, a bridge wire with a charge head, and a gunpowder tube (or a tube without detonating powder), among which the integrated circuit, additional electronic components and bridge wires are all welded on the circuit board. During use, the controller supplies power and communicates with the electronic detonator through the bus, t...
