Problems solved by technology

These locations are often far away from the main roadway, and the roadway is narrow, the environment is harsh and humid, and it is difficult to arrange data lines and power lines
Even if the wire is pulled, it is easy to be broken by mechanical equipment impact, blasting vibration and other natural accidents in actual operation, resulting in abnormal operation of the digital transmission system
Moreover, the wiring area can only cover the main underground roadway, and some branch roadways, mining faces, and excavation faces cannot be effectively covered.

Abstract

The invention discloses a wireless data transmission system and method. The wireless data transmission system comprises a data acquiring device, a base station and at least one data link disposed between the data acquiring device and the base station, wherein the data acquiring device, the data link and the base station form a chained jump transfer structure, and utilize a wireless network to perform step-by-step transmission so as to complete uploading and issuing of data. According to the wireless data transmission system and method, a low power consumption scheme is utilized, wireless data transmission is performed under extremely low duty cycle, and free networking can be achieved in hostile underground environments without being affected by the environment.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a low-power wireless data transmission system and a method thereof. Background technique [0002] Data transmission is an important part of mine safety, petroleum, fire protection, military and other fields. Usually, wired network is used for data transmission, such as network cable, 485 bus, CAN bus, etc. These methods have certain difficulties in wiring requirements, especially in the field of underground work. In some places with harsh conditions, key data need to be uploaded. sensor data, etc. These locations are often far away from the main roadway, and the roadway is narrow, the environment is harsh and humid, and it is difficult to arrange data lines and power lines. Even if the wire is pulled, it is easy to be broken by mechanical equipment impact, blasting vibration and other natural accidents in actual operation, resulting in abnormal operation of the digital transmis...
