Embodiment Construction

[0034] Adjacent channel interference: mainly other uncontrolled base stations that are close to the frequency point of the base station (transmitter) erected by the construction party are also transmitting data (interference data), due to the limited filtering performance of the filter of the mobile station (receiver) , failed to effectively filter, the power spectrum is still relatively large, and the data frame format is the same, so the receiver can receive the interference data.

[0035] Co-channel interference: the same frequency as the working channel, but not the base station (transmitter) that is controlled and assumed by the construction party to transmit data (interference data), because the frequency is the same as the center frequency, it will not be received by the mobile station's radio station (received data). The filter of the side) is filtered out, and the data frame format is the same, so the receiver can receive the interference data.

Abstract

The present application discloses a method, device, base station radio and storage medium for processing RTK radio data frames. The RTK radio data frame processing method provided by this application utilizes the frequency word of the base station radio and the base station identification to generate data verification information, and generates data verification information. The data verification information is inserted into the standard data frame to form a new data frame format. Through the new data frame format and data verification information, the mobile station can accurately receive the RTK data from the correct base station and avoid the same frequency. , adjacent channel interference, leading to the phenomenon of false reception, which solves the technical problem that the existing RTK positioning is easily interfered by the signals of other RTK devices, and the phenomenon of data packet reception occurs, resulting in low operation efficiency.

Description

technical field [0001] The present application relates to the technical field of power distribution networks, and in particular, to a method, device, base station radio, and storage medium for processing RTK data frames. Background technique [0002] RTK (Real-Time Kinematic real-time dynamic differential method) host is a device based on GNSS (Global Navigation Satellite System), which transmits and receives carrier phase differential data in real time through data link, and realizes high-precision positioning solution. It is a device in the field of high-precision measurement today. important equipment. The radio is one of the data links commonly used in RTK host systems. [0003] The working principle of the RTK radio data link is: the base station is set up at a fixed point, and the differential data is transmitted through the base station; within a certain distance, the mobile station operating on the same frequency as the base station will receive the differential dat...
