Description
Technical Field
The invention relates to the technical field of electronic detonators, in particular to an electronic detonator chip for storing detonation information and an electronic detonator fault investigation method.
Background
Compared with the traditional electric detonator, the electronic detonator initiation process is more complex, multiple interactive operations such as delay issuing and password comparison between the initiator and the electronic detonator are increased, and the possible causes of the detonator being not exploded are much more complex than the traditional electric detonator, for example, the possible causes are that the ignition capacitor is damaged, the ignition capacitor is not charged enough, the delay issuing and clock correction cannot be completed, the correct initiation password cannot be issued, and the like. Therefore, if the detonator is found to be unexpired after the on-site detonation, it becomes an important task to check the true cause of the detonator unexpired. However, after detonation, the detonation network is blasted, and a lot of temporary information generated in the detonation process in the electronic detonator chip is lost due to power failure, so that great difficulty is caused in restoring the detonation site and checking the unexplosive reason.
The patent publication numbers CN113138967a and CN101338997B both relate to a "black box" function module for storing the detonation information as well, but they have the common point that the function modules are all arranged at the initiator end and can only store the detonation information collected inside the initiator. For temporary detonation information which is generated in the electronic detonator module in the detonation process and is limited by the state of the field detonation bus and the communication performance thereof and cannot be transmitted to the detonator (or the transmission process may be wrong), the black box functional module cannot acquire the temporary detonation information. However, the detonation information only existing in the electronic detonator is often critical to the investigation, so that the black box functional module has great limitation in investigation of the unexplosive cause of the detonator.
