Embodiment Construction
[0047] As a vehicle-mounted device, the device is installed on a roller compactor used for the construction of earth-rock dam materials and asphalt concrete dam materials. The device mainly includes six parts, such as figure 1 As shown, they are dam material stiffness monitoring module, positioning module, controller unit, power supply module, vehicle-mounted frequency hopping network IP communication module and remote frequency hopping network IP communication module.
[0048] The dam material stiffness monitoring module includes an acceleration sensor and a single-chip microcomputer, which is packaged and installed on the central axis of the vibrating wheel of the roller compactor and does not roll with the vibrating wheel. The acceleration sensor collects the acceleration analog signal of the vibrating wheel in real time, converts the signal into a time-domain digital signal through analog-to-digital conversion, and transmits the time-domain digital signal to the single-chi...
