基于压力监测的汽车起重机平衡防倾翻系统研究

摘要

为了实现汽车起重机工作过程中各支撑点的实时监测,防止起吊负载过大导致汽车起重机倾翻,研究开发了一种基于压力监测的汽车起重机平衡防倾翻系统,通过在汽车起重机与地面接触的四个支撑点处安装压力传感器,实时监测汽车起重机起吊过程中各支撑点的压力变化情况,采用无线传输模块将压力信号实时传输给无线采集终端,无线采集终端与数据分析处理系统连接,对各个压力传感器的数据进行模数转换,并计算受力差值,根据受力差值的变化实时分析载荷特征,实现超限实时预警并停止起吊,该系统为保证汽车起重机的安全稳定作业提供了一种重要技术手段.%In order to realize the real-time monitoring of each supporting point of automobile crane working process, prevent the lifting load is too large to cause the car crane tipping, research and development of a balanced pressure monitoring based on automobile crane rollover protection system, by pressure sensors installed in the four supporting points of auto crane and ground contact pressure changes. The support for real-time monitoring of automobile crane lifting process, the wireless transmission module of the piezoelectric signal real-time transmission to the wireless acquisition terminal, wireless acquisition terminal and data processing system connected to each of the pressure sensor data for analog-to-digital conversion, and calculate the pressure difference, according to the load characteristic of real-time analysis of the changes of pressure difference, beyon the real-time warning and stop lifting, change the system to ensure the safe and stable operation of vehicle crane provides a Important technical means.
