Abstract: |
In order to quantifiably control the casting quality of fresh concrete, integrated kinematic visual monitoring system to determine the trace of vibrator on working site is developed, which can evaluate vibration quality in real time. The working principle of integrated system is as follow:real time tracks of vibrator and vibrating time are achieved firstly by means of RTK(real time kinematics) technology from GPS and special electrode device invented respectively, then wireless data which integrates time and tracks by mono chip computer is sent to terminal computer, and finally, the evaluation of vibrating state and online feedback control of casting are carried out according to visual software evaluation. The test results show that the system could rather well monitor in real time and quantifiably evaluate vibrating process of fresh concrete. |
