Abstract:In view of the actual project needs, a set of state monitoring system is designed for an innovative multi-functional catenary operation vehicle, which can realize the real-time monitoring and motion attitude model tracking such as reinforcing bar detection, drilling anchor, drawing test, hanging column installation, maintenance and so on. The system is designed and implemented based on LabVIEW and CAN bus. In the system, sensors and other lower computer devices are mounted on five CAN buses. After the information is integrated by the controller, it is transmitted to the upper computer software for display through the CAN box. In addition, the software stores all data in the local database created by Access, and important data in the base central database. Finally, the interface display and model attitude tracking function are tested in the field, and the attitude data are used to perform capsizing calculation. The results show that the system program runs stably, the display function is normal, and the model motion synchronization is good. The minimum sum moment of AB overturning line is about 210000, much greater than 0. This indicates that the system can complete real-time monitoring and attitude tracking tasks, and there is no danger of overturning in test conditions.
