Abstract
The invention provides a method for controlling the charging of the priming circuit of an electronic detonator. The method comprises a charging control process of the priming device of the electronic detonator on one hand and a charging control process of the electronic detonator on the other hand. The priming device sends a charging instruction to the electronic detonator; and the detonator compares the detonator identifier code in the instruction with the identifier code of the detonator read by a logic control circuit after receiving the instruction: if the identifier codes are the same, the detonator sends back a charging instruction response, and enters into a charging condition; and if not, the detonator quits the charging process, and keeps on waiting to receive an external instruction. The priming device configures a charging finish marker therein as the state marker of the detonator as soon as the response information sent back is received. The charging instruction comprises m preset synchronous learning probes, charging controlling command characters and an identity code of an electronic detonator which are arranged in sequence. The technical scheme realizes the time-sharing charging of the priming circuit and avoids the impact on the priming circuit caused by synchronous charging.
