FreeRtos-based method for monitoring strain of intelligent construction training bridge floor

The invention relates to a FreeRtos-based method for monitoring strain of an intelligent building practical training bridge floor. Eight strain gauges are pasted on a bridge model, numerical values of a strain gauge sensor acquired by AD7190 are read through an SPI bus, data processing is completed through an MCU, and finally bridge oscillation data are displayed on a front-end page of the bridge oscillation data display device and can also be transmitted to an Internet of Things platform to be displayed. A FreeRtos system is used on the software system; in the aspect of software architecture, event is adopted; in the design of a front-end page, a vue framework is adopted. The method has the following advantages: 1, the data flow is short, and no redundant protocol transmission overhead exists; 2, the equipment carries front and back end services, and can log in an equipment webpage to directly collect display data without carrying an additional server; and 3, the equipment is low in cost but efficient. 本发明涉及
