Problems solved by technology

[0002] At present, the amount of road construction projects in our country is very large, and road quality accidents occur from time to time. One of the main reasons for road quality problems is the road compaction process in the road construction process. The number of repetitions, the second is that the number of repetitions recorded by the operator is wrong or the coverage rate of rolling does not reach 100%

Abstract

The invention discloses a high-precision automatic road rolling control system based on Beidou RN differential locating. The high-precision automatic road rolling control system comprises a mobile locating side which is arranged on a road roller, the mobile locating side comprises a CPU, a radio station, a Beidou RN, a GPRS communication module and a CAN interface, wherein a differential base station is connected to the radio station through a 433M antenna, a Beidou satellite is connected to the Beidou RN through a satellite antenna, a monitoring center is connected to the GPRS communication module through a mobile communication network, and a road roller control system is connected to the CPU through the CAN interface. By means of the high-precision automatic road rolling control system based on Beidou RN differential locating, through the differential base station, centimeter-level high-precision locating of the Beidou RN is achieved, thus the road roller can conduct automatic road rolling, the repeated frequency and the coverage rate of road rolling are remotely monitored, and the road rolling quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic control of road roller operation, in particular to a high-precision automatic road roller control system and method based on Beidou RN differential positioning. Background technique [0002] At present, the amount of road construction projects in our country is very large, and road quality accidents occur from time to time. One of the main reasons for road quality problems is the road compaction process in the road construction process. The number of repetitions, the second is that the number of repetitions recorded by the operator is wrong or the coverage rate of rolling does not reach 100%. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a high-precision automatic road pressure control system and method based on Beidou RN differential positioning with simple structure ...
