A new wireless critical system based on Industrial Internet of Things (IIoT) innovations, a combination of different wireless technologies - from mature well known 2G networks to high performance ultralong range private 169 MHz LoRa network - and a cloud distributed architecture with advanced algorithms is presented to build a critical telemetry system, in this case, applied to real time hydraulic canals monitoring of hydroelectric plants. Thus, sporadic and uncontrolled breaks of hydraulic elements are avoided, decreasing the affection to populations, environment, nearby roads and other infrastructures.
For this pilot deployment 6 different hydraulic canals located in remote sites, some of them without cellular coverage, have been monitored with up to 25 measurement points. The wireless remote terminal units (RTU) have been designed with cutting edge IIoT electronics, enabling ultra-low power consumption and autonomous energy harvesting operation with 3W solar panels; allowing 1-minute sampling time and 5 minutes transmission periods to the cloud, where advanced algorithms, requiring the information of every RTU, update the state and health of the infrastructures in real time.
