[0002] With the development of society and the progress of the construction industry, the construction technology of the construction industry will inevitably move towards a better and faster direction. In order to ease the pressure of construction period and cost, more and more construction projects have begun to explore more advanced and efficient processes and methods. Appearance defects such as cold joints, honeycombs, and rough surfaces are prone to occur at the location of construction joints cast in batches.

The power cord 6 of the vibrating device bypasses the fixed pulley 33 located at the intersection of the transverse slide rail 31 and the vertical pole 32 to avoid wear of the power cord 6 of the vibrating device.

[0043] The vibrating rod 7 is equipped with a Bluetooth locator and a vibration time collection device.

The transformer is set with a primary winding and is directly installed on the power line of the vibrating rod 7 motor. The number of turns of the secondary winding is 2000. The output secondary current is converted to obtain the required voltage value. When the vibrating rod 7 is inserted into the concrete for vibration, the primary side current changes due to the increase in power consumption, which synchronously causes the secondary side current to change, and the circuit conversion voltage value changes. The single-chip microcomputer determines the state of the vibrating rod 7 being inserted and pulled out of the concrete according to the change in the converted voltage value. The vibration information acquisition box is composed of a custom-developed single-chip microcomputer board and accessories such as a transceiver station. The system single-chip microcomputer uses wireless radio frequency to continuously receive real-time information data on the vibration status of the vibrating rod 7 head position, and then transmits it to the mobile workstation via Wi-Fi.
