Grid IoT Reference Design: Connecting Fault Indicators: Data Collector: Mini-RTU Using Sub-1GHz RF
Description
The TIDA-00816 reference design has wireless sub-1 GHz communication in a star network between multiple sensor nodes (in this case: fault passage indicators) and a collector using the TI 15.4-stack. This design is optimized for low power consumption for short range (< 50 m) using overhead fault passage indicator (FPI) and a data collector in distribution automation as an application scenario. The CC1310 device from TI's Simplelink family is a highly-integrated: single-chip solution incorporating a sub-1 GHz radio frequency (RF) transceiver and an ArmTM CortexTM M3 MCU. TI 15.4-stack is used to configure beacon mode communication over the US: ETSI: and China frequency bands. Current consumption data is available for a single packet data transfer of 1–300 bytes at a 50-kbps data rate by optimizing transmit power levels (0 to +10 dBm) and beacon intervals (0.3–5 s).
Features
- Low power consumption for short range communication (≤ 50 meters) for FPI: data collector: substation and distribution automation end equipment:Receive current below 6 mA and transmit current below 16 mA (at +10 dBm)Average current consumption below 20 µA for five second beacon interval (sensor node in receive mode) in a star networkCurrent consumption data provided for US (915-MHz): ETSI (868-MHz): and China (433-MHz) frequency bandsIntegrating low power RF in grid automation with details on:Network setupBeacon transmission and receptionData exchangeFault identification and data communicationAdvantages of using CC1310:Low active RF and microcontroller (MCU) current consumption with standby current of 0.7uA with RTC running and RAM and CPU retentionTI’s 15.4 stack is used to configure beacon-enabled communication between collector and sensor (fault indicator) nodeTI SimpleLinkTM platform enables seamless integration with MCU portfolio
