Abstract:Total station, as a representative of modern surveying technology, plays an important role in land surveying, construction engineering and other fields, the traditional total station has operation and data transmission limitations, and the development of Internet of Things technology to make the total station smarter and more efficient, the data transmission and command control of the total station as well as the AliCloud IoT platform are studied, and a total station remote control system based on IoT technology is designed, and the gateway adopts the single-chip computer The gateway adopts STM32F103RCT6 as the control chip, and establishes network connection with AliCloud IOT platform through 4G module, and the MQTT protocol is used to realize data transmission between the gateway, AliCloud IOT platform, and the mobile phone APP, which ensures that the data transmission is safe and reliable; and the user realizes the real-time monitoring and remote control of the total station and the remote control of the total station by using the APP. Users use APP to realize real-time monitoring and remote control of total station, and at the same time, the system has the functions of data management and report generation, etc. After practical application, the accuracy of system data transmission is 100%, which meets the basic function of total station measurement in the project, and improves the convenience and efficiency of operation.
