Problems solved by technology

At present, the electronic detonator detects the electronic detonator through the detonator before detonation. It can detect the short circuit of the line, the open circuit and the open circuit of a certain detonator. It cannot detect whether the line is leaking. The detonator is blinded due to insufficient energy caused by electric leakage. At the same time, the detonator is used to detect the line, which has potential safety hazards

Abstract

The invention relates to the field of detection of electronic detonators and particularly relates to a detonator network detector and detection method. The detonator network detector aims at solving the problems of network state detection before the blasting of electronic detonators. The electronic detonator network detector can detect short circuit, circuit breakage, creepage and other situations of an electronic detonator network with low voltage and low current, and the electronic detonators are intrinsically safe during the whole detection process. According to the electronic detonator network detector and detection method, the state detection of the electronic detonators of the electronic detonator network can be completed by a power supply unit, an output voltage selector, a sampling circuit, a display control unit, a processor and the like which are matched for treatment. The electronic detonator network detector and detection method disclosed by the invention are mainly applied to the field of state detection of the electronic detonators.

technical field [0001] The invention relates to the field of electronic detonator detection, in particular to a detonator network detector and a detection method. Background technique [0002] When the electronic detonator is used in engineering blasting, after the entire network is connected, it is necessary to detect the connection, disconnection, short circuit and leakage of the network before detonation. At present, the electronic detonator detects the electronic detonator through the detonator before detonation. It can detect the short circuit of the line, the open circuit and the open circuit of a certain detonator. It cannot detect whether the line is leaking. The detonator is blinded due to the lack of energy caused by electric leakage. At the same time, the circuit is detected with the detonator, which has potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electronic detonator ...
