The Design of Wireless Monitoring System Based on the High-Speed Rotating Fan of the STM32

Abstract

In view of the traditional measurement system is not easy to install and design shortcomings, such as volume and requires a lot of wiring, This system used STM32 microprocessor and CC2530 ZigBee wireless technology to achieve the acquisition of High-speed rotating strain, high-speed storage, wireless monitoring system. This system can be used to replace manual operation, make the test more intelligent, more convenient and more accurate. This article used the STM32F103 chips as the main control system chip, implement the collection and storage function, CC2530 ZigBee protocol implemented wireless transmission function. Acquisition module used the high-speed AD transform chip ADS1274, Four-way synchronization acquisition, which convert digital signal transmit to the main control chip, the main control chip collected data which stored in the high capacity SD card. When need data, the system get the data from the SD card by zigbee wireless transmission to the monitor software. This system used the hardware filter and software filter, join the manning window, which reduced the influence of noise and improved the system accuracy. This paper had solved the monitoring question of the high-speed acquisition structure, implemented the function which data collection, storage and remote control for the integration, according to testing, the various technical indexes reach the system requirements[1].
