Description

Technical Field

[0001] This utility model relates to the field of electronic component testing, and in particular to a testing system for an industrial electronic detonator electronic control module. Background Technology

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, use electronic control modules to control the detonation process. They can control the detonation delay time and other parameters, and can also perform ignition element status testing and controller communication functions. Compared to industrial detonators, electronic detonators offer higher safety. As an important alternative to traditional pyrotechnics, electronic detonators have demonstrated significant application value in numerous engineering projects due to their high precision, high reliability, and safety advantages.

[0003] As a core component of electronic detonators, each electronic detonator must be equipped with one, leading to a surge in market demand. As a core component of industrial electronic detonators, its performance and reliability are closely related to life safety, resulting in high testing and inspection requirements. Currently, WJ / T 9108 "Electronic Control Module for Industrial Electronic Detonators" is the only domestic standard that comprehensively tests electronic control modules, including 23 testing requirements covering general requirements, electrical performance, electromagnetic compatibility performance, and environmental reliability performance.

[0004] Traditional testing of industrial electronic detonator electronic control modules typically relies on multiple independent instruments and equipment to separately complete communication, charging, discharging, parameter measurement, and safety performance testing. This method suffers from low efficiency, cumbersome operation, large human error, and difficulty in unified data management and traceability. Especially for safety and reliability tests requiring large-sample statistical analysis (such as SCK and ROK calculations), as well as complex networking and aging tests, traditional methods are inadequate.
