With the development of the times, the requirements for the accuracy and stability of indoor positioning continue to increase. Ultra-Wideband (UWB) positioning has been widely used with its extremely high resolution and anti-multipath characteristics, and has become a prominent representative of indoor positioning technology. This essay studies the application of UWB wireless communication and positioning technology in the field of indoor positioning. In view of this situation, this paper intends to discuss the application of UWB technology in indoor real-time positioning and discuss the advantages of UWB technology in achieving indoor accurate positioning from the aspects of ranging principle, positioning algorithm and error source.

This paper intends to develop an intelligent unmanned warehouse based on the Internet of Things. Through the combination of informatization, Internet of Things and mechatronics, multiple logistics forklifts can run at high speed at the same time, greatly improving the operation efficiency and accuracy, and reducing the cost of warehouse management. The automatic logistics forklift is based on the powerful processing capability of STM32F767 to perform arithmetic processing on the logistics network, and guide the automatic logistics forklift to complete accurate high-speed movement according to the laid signals. At the same time, the intelligent unmanned warehouse uses the Internet of Things technology to obtain the logistics forklift. In order to handle the real-time status of warehouse goods, completely unmanned transportation can be realized; finally, intelligent unmanned warehouses effectively use automatic three-dimensional storage, visual recognition and other technologies to achieve efficient collaboration between equipment, machines and systems.
With the rapid development of intelligent vehicle technology, the intelligent requirements of parking space recognition technology are getting higher and higher. This paper intends to develop an automatic parking system based on the STM32F767 embedded system, which is used for automatic parking in the parking lot. The automatic parking system uses third-party smart forklifts to autonomously patrol lines and identify vehicles, and transport them to designated parking spaces. Through the flexible movement of omnidirectional wheels, a series of auto-matic parking functions such as autonomous line inspection, environmental perception, networking processing, parking space planning, lifting vehicles, and omnidirectional motion are realized. Aiming at the difficulties in automatic parking, such as the kinematics of vertical parking spaces, horizontal parking spaces, and inclined side parking spaces, research is carried out to ensure that the vehicle can accurately move to the designated position without obstacles. The automatic parking system has the characteristics of high recognition rate, good safety, and fast parking speed. Combined with the human-computer interaction interface of the Internet of Things, the parking situation of the parking lot and the occupancy of the parking space are clear at a glance, which greatly improves the operation efficiency of the whole system.
