1. A detection device comprising:
an acquisition unit for acquiring posture information of a work implement having at least one of a bucket, an arm, and a boom of a construction equipment;
a first communication unit for transmitting the posture information to an interface unit as a target on which level information of the work implement is displayed;
a control unit for producing a zero point signal; and
a second communication unit for communicating with other construction equipment,
wherein:
the control unit produces the zero point signal if specific posture information is received from other construction equipment through the second communication unit;
the first communication unit transmits the specific posture information and the zero point signal to the interface unit; and
the zero point signal controls the interface unit to allow specific level information on which the specific posture information is reflected to be set to a reference value; and
the first communication unit assigns unique identifiers to pieces of detailed information constituting the posture information, wherein:
the first communication unit wirelessly transmits a packet comprising a set of the unique identifier and one of the pieces of detailed information to the interface unit; and
the unique identifiers are used in restoring the posture information through combination of the pieces of detailed information in the interface unit.
