Real time Wireless Data Acquisition and Fault Monitoring using DSP processor TMS320F2812 with CPLD interface

In order to save numerous man power hours fritter away to monitor various process parameters in industries whole day, the design presented in this paper gives solution to acquire data at desired rate and monitor fault with alarm system. The design introduces wireless information flow between on field acquisition and remote monitoring part at the office. DSP processor TMS320F2812 which is a very low cost DSP processor; with its 32-bit CPU timer offer real time operation utilizing interrupts. The design presented gives multi edge benefits of signal processing besides employing wireless medium for remote transmission of acquired data in highly secured medium. Cypress made Radio Frequency transceiver CYWUSB6935 using Direct Sequence Spread Spectrum (DSSS) modulation interfaced with DSP processor using Serial Peripheral Interface (SPI). The design represents extended External Interface (XINTF) of the DSP processor by means of programming CPLD XCR3256. The data is available to the monitoring computer on one press of button without laying long cables in maladroit industry environment. This leads towards automation and cost saving solution for industries. It can be modified to handle very low sampling rate creating database of long time as well as to the real time alarm generation system. The design can be enhanced for various applications like remote security system, RF counting of inventory, traffic monitoring system, weather control system and many more.
