BMS
A collection of systems with numerous signal and data source. When it is built, it is built!
Mobilized BMS Data
BMS needs more Sensor Data
Latest technologies creates a lot of sensor data.Chinotech provides smart ways to integrate these data points back into the BMS,without the hassle of wiring and data transformation.
For example, water leakage sensor on roof top;access control and occupancy data;Elevator monitoring data;firing system data, etc

HIT IT infrastructure for data storage
Meter data convert to wireless signal gateway forwards meter data to HIT infrastructure meter data arrives at HIT DB
Zigbee + LoRaWan
City & Building Wide Sensor Deployment- Uni-directional sensor data- control of sensors not favorable (LoRa constraints)- in-frequent monitoring (e.g. once per day)e.g. water meter
Smart Home / Office Controllable Sensor Deployment- Bi-directional sensor data, setting- Control signal is included in Zigbee spec- frequent monitoringe.g. electric meter with on / off feature
