ABSTRACT
With the acceleration of people's life rhythm and the diversification of travel needs, convenient and intelligent travel assistance tools have become an important requirement for improving the efficiency of daily life. Traditional travel preparations often rely on manual inquiries about the weather and time planning, which have problems such as scattered information acquisition and delayed responses, making it difficult to meet modern people's needs for efficient and accurate travel.
The intelligent travel assistant based on the STM32F103C8T6 microcontroller integrates a DS18B20 temperature sensor, a rain monitoring module, a DS1302 clock module, an SU-03T voice recognition module, a TTS voice broadcast module, buttons, an OLED display, and a GPS + Beidou positioning module, realizing the automatic monitoring of travel-related information and intelligent auxiliary functions. The core functions of the system include: real-time monitoring of ambient temperature through the DS18B20, and informing users of the current temperature and recommending suitable clothing in combination with the TTS voice broadcast module; perceiving rainfall through the rain monitoring module to provide rainproof reference for travel; obtaining real-time time with the help of the DS1302 clock module, supporting setting alarms through buttons, and triggering sound and light alarms to remind of travel time when the alarm time is reached; receiving user instructions through the SU-03T voice recognition module to realize voice interactive control; real-time display of temperature, time, alarm settings and positioning information through the OLED display; determining the current location by using the GPS + Beidou module to provide location reference for travel route planning.
This design effectively improves the convenience and intelligence level of travel preparations, integrates various key travel information such as temperature, weather, time and positioning, reduces the tedious process of manual inquiry, provides users with a one-stop travel assistance solution, and also provides a reference for the research and development of similar embedded intelligent auxiliary equipment, which has high practical application value.
