An electronic detonator control chip (100) includes a charge control circuit (110), a firing control circuit (105), a logic control circuit (106), a safe discharge circuit (108) etc., and especially includes a detecting circuit (111). The detecting circuit (111) is controlled by the logic control circuit (106), and outputs an achieved signal to the logic control circuit (106) to detect whether the circuits connections of the charge control circuit (110), the firing control circuit (105), the safe discharge circuit (108), an energy storage device (203), a firing device (204), or the loop consisted of the combination of the above five components are correct. And a method of detecting the connection correctness of the chip (100) includes: first, detecting the initial working state of the chip (100); second, detecting the charging loop; afterward, detecting the firing loop or the safe discharge loop; again, charging the energy storage device (203); in succession, detecting the undetected loop in the firing loop or the safe discharge loop; finally, resetting the chip (100) to the initial working state. |
