提升机天轮应力检测方法与装置
摘要：
一种提升机天轮应力检测方法与装置，在提升机天轮上固定应力无线传感器节点，在天轮支架上固定无线传感器网络协调器，并用RS-232总线连接无线传感器网络协调器与工控机，对系统初始化，设定采样频率，设定时钟同步，按照设定的采样频率启动应力无线传感器节点，应力无线传感器节点将收集的信息发送到无线传感器网络协调器，无线传感器网络协调器对接收到应力无线传感器节点的信息预处理，然后通过RS-232总线将数据发送给设在操作台上的工控机，工控机将接收的应力无线传感器节点信息分析处理得到提升机天轮的应力数据。其方法及结构简单，稳定性强，可靠性高，安装、维护方便、成本低、灵敏度高、能够用于深井检测。
摘要（英）：

The invention discloses a method and a device for detecting the stress of a hoisting machine head sheave. A stress wireless sensor node is fixed on the hoisting machine head sheave; a wireless sensor network coordinator is fixed on a head sheave support; the wireless sensor network coordinator is connected with an industrial personal computer by a RS-232 bus. The method comprises the following steps: a system is initialized; a sampling frequency is set; clock synchronization is set; the stress wireless sensor node is started according to the set sampling frequency; the collected information is sent to the wireless sensor network coordinator by the stress wireless sensor node; the information receiving the stress wireless sensor node is preprocessed by the wireless sensor network coordinator; the data is sent to the industrial personal computer arranged on an operation platform through the RS-232 bus; and the received information of the stress wireless sensor node is analyzed and processed by the industrial personal computer to obtain the stress data of the hoisting machine head sheave. The invention has simple method and structure, strong stability, high reliability, convenient installation and maintenance, low cost and high sensitivity, and can be used for detecting deep wells.
