Problems solved by technology
[0006] (1) In the prior art, the two-way safety protection method for railway field operations based on radar technology only uses radar to detect the running state of the train. Because external moving objects also emit high-frequency electromagnetic waves that radar generates, it is easy to cause radar misdetection. Affect the normal progress of on-site construction;
[0007] (2) The two-way safety protection method for railway field operations based on radar technology in the prior art cannot track the motion state of the train in real time, and the safety distance is not easy to set and adjust, which poses a certain threat to the safety of on-site construction personnel

The invention discloses a railway field operation two-way safety protection method based on a radar technology. The railway field operation two-way safety protection method based on the radar technology comprises the steps of S100, obtaining a detection signal of a two-way train motion state by using a signal detection unit; S200, analyzing and processing the detection signal of the two-way trainmotion state by using the terminal control unit; and S300, reminding construction personnel by using a pre-warning unit according to a detection signal analyzing and processing result. According to the railway field operation two-way safety protection method based on the radar technology, by using a combined mode of radar detection and train track vibration detection, the train motion state is captured to avoid false detection caused by single radar monitoring and greatly improve the collection accuracy of the train motion state; and meanwhile, according to the railway field operation two-waysafety protection method based on the radar technology, as a train entering a detection range is monitored in real time, and the field construction personnel are reminded of the motion state of the train in real time by using the pre-warning unit, damages to the field construction personnel in the train advancing process are prevented.
Description
technical field [0001] The invention relates to the field of safety protection, in particular to a radar technology-based two-way safety protection method for railway field operations. Background technique [0002] Radar detection technology is essentially a high-frequency electromagnetic wave transmitting and receiving technology. The radar wave is generated by its own excitation, and directly transmits radio frequency electromagnetic waves to the roadbed. The sampling signal of the roadbed is obtained through the reflection and reception of the wave, and then the detection result is obtained through the hardware, software and graphic display system. The sampling frequency used by radar is generally a few megahertz, and some radio frequency frequencies for transmission and reception must reach more than gigahertz. Due to the outstanding advantages of non-destructive, fast, simple, and high-precision radar detection technology, it was applied in the monitoring of highway co...
