Abstract

The present disclosure relates to a wireless communication system and communication method for a cableless detection robot for a gas pipeline. The wireless communication system includes an antenna assembly, a repeater assembly and a repeater retracting device, wherein the antenna assembly is fixed to the gas pipeline and extends into the interior of the gas pipeline, the repeater assembly is provided with at least one set, and the repeater retracting device is connected to the robot and used for retracting the repeater assembly along the gas pipeline, the antenna assembly, the repeater assembly and the robot are connected through a wireless signal having a wavelength less than 3.41r, wherein r represents the radius of the gas pipeline. The wireless communication system has the advantages of simple structure, low cost, convenient use, safety and reliability, and solves the problem that the automatic force cableless detection robot cannot perform a long-distance internal detection operation due to shielding wireless signals by the pipeline. The communication method has the advantages of easy implementation, convenient control and reliable communication.
