Embodiment 1

[0181] Such as Figure 1a As shown, the hardware composition of this embodiment includes Beidou satellite monitoring point equipment, IoT sensor monitoring device, spatial data preprocessing platform, NB-IoT communication module, solar battery, power management module, input and output panel and background data monitoring platform . The Beidou satellite monitoring data and the tower deformation fusion data collected by the IoT sensor monitoring device are forwarded to the wired spatial data preprocessing platform via the NB-IoT communication module for preprocessing. The transparently transmitted raw data is preprocessed by the main control module for the spatial data preprocessing platform of the MSP430F169 microcontroller, and then sent to the outside world through the USIM interface and the radio frequency core module. The solar cell is connected with the power management module, and is used for powering the Beidou satellite monitoring point equipment, the IoT sensor monito...
