Detection and control process of equipment dedicated to electronic detonators

Abstract

The invention provides a detection control flow of special equipment for an electronic detonator. The equipment is connected with the electronic detonator through a lead. The equipment executes a process of new detonator detection to determine that a new detonator is successfully connected to the equipment; a current detection process is executed to detect electrical properties of the new detonator, so as to determine whether a wire current increment caused by the detonator is within an allowed scope of a detonator working current; an identity code detection process is executed to determine whether an identity code form and identity code information of the new detonator are qualified; a function detection process is executed; one or more processes of a detonator self-detection process, a clock frequency detection process and a detonator cipher detection process are executed to detect detonator functions. According to the technical scheme, determination of detonator eligibility is realized; the detection to the detonator of the scheme is more complete, so as to further ensure security, reliability and accuracy of the detonator product during usage, and raise detection efficiency.

Description

technical field [0001] The invention relates to the technical field of pyrotechnic applications, in particular to a detection control process for detecting the performance and function of an electronic detonator. Background technique [0002] In the process of production and use of electronic detonators, the qualification of the detonator needs to be tested to ensure that the performance of the product meets the requirements of use. [0003] The patent application document 200810108688.X presents the realization scheme of the detection circuit in the electronic detonator control chip and the method for detecting the connection reliability of each component in the electronic detonator. The control device outside the detonator sends a detection command to the electronic detonator; the chip enters the detection state under the control of the device, and automatically completes the self-detection of the detonator control circuit. This self-test process includes charging circuit...

AI Technical Summary

Problems solved by technology

[0004] The main defect of the above-mentioned technical solution is that the self-testing process of the detonator chip is only for the detection of the necessary functions during the use of the detonator. For other content, such as whether the working current is within the allowable range, whether the detonator’s identity code and / or password are accurate, actual Whether the deviation between the clock frequency and the design value is within the allowable range is not tested, so that the reliability of the detonator product performance and the completeness of the function cannot be guaranteed, which brings hidden dangers to the safety and reliability of the detonator.
