1. An automatic sensor identification system in a construction machine, wherein the construction machine is provided with an articulated working machine installed on a vehicle body and configured by rotatably connecting multiple front members, a front member driving means for driving each of said multiple front members, multiple posture information detection sensors mounted on said multiple front members respectively for detecting posture information of said front members, and a control unit configured to calculate a posture of front members based on detection signals from the posture information detection sensors; and wherein, when providing the automatic sensor identification system for performing an identification task to identify which one of said multiple posture information detection sensors is mounted respectively on which front member, the automatic sensor identification system comprises:
a task starting means operated for starting the identification task,
a front member control means for outputting a control instruction to said front member driving means to drive and stop said multiple front members sequentially, individually, and automatically in response to the task starting means being operated for starting the identification task, wherein automatic drive and stop processes of the multiple front members by the front member control means go on only when a task progression means is operating, and when the operation of the task progression means is stopped, the automatic drive and stop processes of the multiple front members are stopped, wherein the task progression means is also used as the task starting means, and
a sensor identification means for identifying the posture information detection sensor mounted on each front member based on changes of a detection value from the posture information detection sensor as said each front member is driven by the front member control means; and
upon identifying each posture information detection sensor, the control unit stores a correspondence between an identifier number of each sensor and its associated front member in memory.
