Data topology diagram:
ZHC0921/ZHC0931
ZHC0921/ZHC0931 is a LoRa wireless concentrator ZHC-GW8000 paired with two LoRa nodes.
ZHC0921 supports the interface: RS485/AI/DI, and ZHC0931 supports the interface: RS485/DO. The node does not need to be configured. The hardware DIP switch determines the spreading factor and communication channel. When it is powered on, it can connect to the network and build a private network with the concentrator.
ZHC0921 is a data collection terminal based on the LoRa private protocol, which communicates with the concentrator ad hoc network, concentrator and server through the ZHC private protocol.
Main Feature:
- No software is required to configure the node
- Time division multiplexing to improve communication efficiency
- Stand by5Device types
- Type R supports a serial port collection command, which can intercept collection responses; supports transparent transmission
- Type A supports one-way AI acquisition, and can be configured with 3 trigger reporting modes
- Type D supports one-way DI collection, and can be configured with 3 trigger reporting modes
- Type AD supports one-way AI and one-way DI collection, and 6 trigger reporting modes can be configured
- Type E supports collection to meetMultifunctional energy meter with DL/T645 protocol
- Support active detection
