The Basic Working Process Of The Hoisting Safety Monitoring System For Long-Arm Cranes And The Role Of Each Module

1. In the process of crane operation, the real-time data of the working angle of the boom, the real-time data of the variable oil pressure and the switching signal are collected by various special sensors.

2. The signal conditioning module processes the transmitted real-time data into a signal acceptable to the analog-to-digital conversion chip, and transmits the corresponding conversion result to the main control unit.

3. The main control unit uses the parameters obtained by the conversion according to the mathematical model, calculate the real-time lifting weight of the crane and the corresponding rated lifting weight, and displays the key parameters on the large-size LCD screen to provide the operator with intuitive working condition information.

4. At the same time, the main control unit judges whether the current working state of the crane is within the safe range according to the load rate by comparing the real-time lifting weight and the corresponding rated lifting weight under the same working range.

5. In addition, the use of the touch screen allows the user to set various torque monitoring parameters and boom structure parameters for cranes of different specifications, greatly increasing the general performance of the monitoring system. The USB and serial ports included in the PC communication module not only facilitate downloading and processing data records in the memory card through the host computer, but also upgrade and maintain the firmware and application programs of the monitoring system through the host computer, and enhance the scalability of the monitoring system.
