Description

Technical Field

[0001] The utility model relates to the technical field of electronic detonator detection, and more specifically, to an electronic detonator detection device. Background Art

[0002] Electronic detonators are electronic devices used to detonate explosives. They are widely used in mining blasting, military engineering, and construction. Compared to traditional pyrotechnic detonators, electronic detonators offer greater reliability, precision, and safety, and can be controlled and used under more complex conditions. They primarily consist of microelectronic circuits, sensors, and initiation devices.

[0003] During the three-code binding process on the electronic detonator production line, the electrical performance of the electronic detonator's leg wire is tested. Detonators that fail this test are moved to the unqualified workshop for further processing. During this test, workers touch the ends of the leg wire to the ends of a multimeter. The inspector determines whether the detonator has been properly processed by observing whether the multimeter reads correctly. Furthermore, the multimeter screen is typically dim, making the test results less intuitive and inconvenient for quick testing. This can be particularly impactful for inspectors with poor eyesight, hindering inspection efficiency. Utility Model Content
