The invention provides an automatic travelling crane hoisting operation safety alarm system and safety alarm method, and the method comprises the steps: a weight sensor is arranged on a lifting lug of a steel coil clamp, collects weight data in real time, and transmits the weight data to a PLC control system in real time; the load sensor is arranged on a clamp mouth of the steel coil clamp to sense whether the steel coil clamp lifts a steel coil or not, and transmits a sensing signal to the PLC control system; the PLC control system judges whether the steel coil is lifted by the steel coil clamp or not according to the induction signal; when the steel coil is lifted by the steel coil clamp, taking the weight data acquired by the weight sensor at the moment as the weight data of the steel coil; when the steel coil clamp lifts the steel coil to run, the PLC control system compares weight data received in real time with steel coil weight data, and if the absolute value of the difference value between the weight data and the steel coil weight data is larger than a first threshold value, the PLC control system controls the traveling crane to stop running and sends an alarm signal to the monitoring terminal. The problem that an automatic travelling crane cannot be stopped in time when encountering an obstacle during steel coil hoisting is solved.

    本发明提供一种自动化行车吊物运行安全报警系统及安全报警方法,包括重量传感器设置在钢卷夹钳的吊耳上实时采集重量数据,并将重量数据实时传输给PLC控制系统;载荷传感器设置在钢卷夹钳钳嘴上感应钢卷夹钳是否将钢卷吊起,并将感应信号传输给PLC控制系统;PLC控制系统根据感应信号判断钢卷是否被钢卷夹钳吊起;当钢卷被钢卷夹钳吊起时,取此时重量传感器采集到的重量数据为钢卷重量数据;在钢卷夹钳吊起钢卷运行时,PLC控制系统根据实时接收到的重量数据与钢卷重量数据相比较,若重量数据与钢卷重量数据的差值的绝对值大于第一阈值,PLC控制系统控制行车停止运行并给监控终端发送报警信号。解决自动化行车在吊运钢卷碰到障碍物时无法及时停车的问题。
