Environment Parameter Detection System Based On STM32 MCU For Intelligent Barracks

With the continuous development of intelligence barracks, the requirement of the army barracks environment constantly tends to the direction of automation, intelligent, modular and highly integrated, While Internet of things technology has played a vital role in the process of the construction of intelligent barracks. As fundamental technical support of the Internet of things, detecting technology based on sensors can detect the barracks environmental basic parameters such as pressure, temperature in real time, dynamic display it,and remote transmit related data. It can be widely used all kinds of detection, control, analysis subsystem in intelligent barracks.The environment parameters detection system based on STM32 MCU for intelligent barracks introduced in this thesis, selects the STM32 MCU as the main control chip, uses one-piece LPS331 AP air pressure and temperature sensor to collect environmental parameters data, transmits data with USART, SPI and Bluetooth module, and realize the realtime dynamic display the environment pressure and temperature parameters in LCD and remote terminal based on the Android platform. The thesis mainly completes the design and implementation of the environment parameters detection system hardware and software, and introduce it from the following aspects:(1) There is a brief description of the concept and function of the intelligent barracks carried on the brief explanation at the beginning. Planning and analyzing the hardware module and software implementation scheme of the system, we designed the overall structure of the environmental parameters detection system for intelligent barracks with the STM32F103RCT6 microcontroller and LPS332 AP sensor.(2) The system hardware design. The hardware of the system consists of four parts, the main control chip and the expansion board module, data acquisition module, remote data transceiver module and data display module. The main control chip and its expansion board mainly include STM32F103RCT6 micro controller, power circuit, debugging circuit and auxiliary circuit, which is the core of the whole system. The data acquisition module is onepiece LPS331 AP air pressure and temperature sensors, which complete environmental parameter acquisition. Remote data transceiver module consists of ATK- HC05 Bluetooth module, which send real-time data to the terminal based on the Android platform. Real-time dynamic display of the pressure and temperature data collected by the system showed on the 160’000 colors TFTLCD true color screen that called data display module in system.(3) The system software design. Including the pressure and temperature data collection, SPI and USART interface communication, TFTLCD screen display, wireless transmission and other modules design, the software design of system is completed by using MDK 5 integrated development environment and other related software tools on the basis of the system hardware design, which Mainly analyzes the implement method of the environment parameter acquisition, transmission and display, as well as the software implementation process in the STM32 platform.The environment parameters detection system based on STM32 MCU for intelligent barracks described in this thesis has good stability and reliability proved by the test run. The design function of the environment parameters detection system is achieved, which basically satisfied the expected design index, and it provided the underlying technology support for intelligent barracks technical implementation.
