根据塔式起重机特点,提出了设备健康监测的概念与方法,把起重臂的振动频率作为判定结构缺陷的识别源,同时也将起重臂的振动幅度作为监控对象。提出了确定监测参数的阀值方法,并应用物联网技术开发了监测系统,变原有安全保护装置的被动保护为主动防御监测,有助于提高设备的安全度。 According to the characteristics of tower crane, the concept and method of equipment health monitoring are put forward. The vibration frequency of boom is taken as the identification source of structural defects, and the vibration amplitude of boom is taken as the monitoring object. A threshold method for determining monitoring parameters was proposed. A monitoring system was developed based on Internet of Things technology. The passive protection of the original safety protection device was taken as active defense monitoring, which helped to improve the safety of the equipment.
