KIO Ø 800 D400 manhole cover
The Smart KIO Sensor system, an intelligent system for monitoring sewerage distribution networks, has been installed inside a number of manholes in the historic centre of Brescia.
The innovative system consists of a level sensor positioned inside the manholes which triggers an alarm when the water level exceeds a certain threshold.
The sensor can also be combined with an anti-intrusion sensor that is activated in the event that the KIO manhole cover is opened.
Alarms are transmitted to a Gateway that sends the data to a Cloud-based Management/Remote Monitoring Centre for processing, storage and real-time alarm management.
The LoRaWAN protocol is used for data transmission, which is a radio frequency protocol that enables long-range communication with low power consumption.
A2A Smart City has made its LoRaWAN network infrastructure and Network Server available to enable sensors and meters across entire city areas in northern Italy.
The sensors were designed and developed by Nexus TLC, a leading innovative SME in the Internet of Things.
Nexus TLC develops innovative, remote-monitoring and control solutions in a number of areas, including safety, efficiency and sustainability.
Transmission is made possible owing to the use of the KIO manhole cover and, in particular, to its main feature – the material from which it is made allows passage of electromagnetic waves and, therefore, blends in with the increasingly advanced wireless systems that will appear in the smart cities of the future.
Each KIO manhole cover is identified using a unique serial code. At the time of installation, mapping between the manhole cover code and address is carried out, which allows each individual manhole cover to be located geographically and values or alarms analysed.
Currently, water level monitoring solutions on the market use GSM/GPRS technology for data transmission.
The benefits of LoRaWAN technology over GSM/GPRS technology are the following:
