Description

Technical Field

[0001] This application relates to the technical field of digital electronic detonator detection, and particularly to a coal-permissible digital electronic detonator detector and method, a computer, and a storage medium. Background Art

[0002] Digital electronic detonators are all controlled by electronic components. The differences in the performance parameters of electronic components are important factors leading to misfires and missed detonations during mining operations. Therefore, it is very necessary to detect each detonator before blasting. Since many coal mine explosives and digital electronic detonators are stored underground in coal mines, the detection of digital electronic detonators must be carried out underground. For example, using a detonator to detect digital electronic detonators poses a major safety hazard.

[0003] Currently, the detection of digital electronic detonators underground mainly relies on the following methods and equipment: 1. Manual testing: Use a multimeter, oscilloscope or special testing instrument to measure the electrical properties of digital electronic detonators individually, such as resistance, communication response, etc. This method relies on manual operation, has low efficiency, is easily affected by human factors, and is difficult to achieve batch detection. 2. Semi-automatic detection equipment: Some enterprises use semi-automatic testing equipment, which is controlled by a single-chip microcomputer or PLC to test the electrical properties of digital electronic detonators, such as resistance, trigger current, communication stability, etc. Such equipment usually requires manual placement of detonators, the testing process is relatively single, the detection standards are limited, and it is difficult to comprehensively detect detonators. 3. Fully automatic detection and screening system: Some high-end production lines are equipped with an automated detection system that can batch-detect the electrical properties and communication status of detonators and classify and screen them. However, these systems usually have high costs and are suitable for large-scale production enterprises. Small and medium-sized enterprises are difficult to afford. At the same time, some systems still have deficiencies in detection accuracy and anti-interference ability.
