Abstract:

In order to enhance the construction safety of high-altitude work basket operators, a study was conducted on an intelligent safety rope lock detection system. This system is capable of accurately measuring whether the lock is in a closed state. The system utilizes a combination of a resonant circuit and a signal processing chain to achieve precise monitoring and identification of the lock's status. The square wave signal generated by the main control chip is resonated through the resonant circuit, ultimately producing the desired sinusoidal wave output. After signal processing through filtering, rectification, and voltage amplification circuits, the signal is transmitted to a comparator circuit for further analysis. The comparator circuit is used to compare the signal with a preset threshold in order to determine the lock's status. The system successfully detects the closed state of the lock and displays it to the construction personnel. The accurate experimental results have far-reaching implications for improving the safety and controllability of high-altitude operations. By integrating multiple key modules into the system design, it reduces the risk of accidents caused by unlocked locks and provides timely warnings to operators, making the workplace safer and more reliable. This underscores the critical role of electronic information technology in engineering safety.
