USR-L101-L-C | 398Mhz~525Mhz |
USR-L101-H-C | 803Mhz~930Mhz |
USR LoRa gateway USR-LG220 has internally installed USR private protocol. LG220 can realize sequential data transmission of multiple nodes
without mutual interference and data encryption to make transmission security and accurate. Networking is connection between multiple nodes
and USR LoRa gateway USR-LG220 which can realize transmission from terminal to Cloud and user doesn’t need to care much about middle stages.
Flexible and convenient networking can realize configuring work mode according to different application environment to be applied in diversity program.
TDM technology is to accurately transmit different signal at different times without mutual interference and user can receive accurate signal in the outdoors
wide area.
To reduce interference when user is uploading data and increase the data transmission accuracy, node active reporting mode has timing reporting
and early-warning reporting. Timing reporting will configure data reporting time for every node, wake up user device by timing node and upload
data; in early-warning reporting mode, user device will wake up LoRa node to upload data. Node active reporting mode is suited to smoke detector,
gas detection, trash can detection, smart oil field, etc.
In the process of multiple nodes transmission, system will automatically configure data transmission time coordinate for every node and all nodes
will do sequential data transmission with LoRa gateway according to time coordinate.
Polling waking mode can reduce server load and LoRa gateway can automatically send data to node by simple configuration. For example, polling
node by Modbus command without server sending command and it can save network data flow. Polling waking mode is suited to smart metering,
sluice control, temperature and humidity monitor of granary, Modbus polling application, etc.
LoRa module can realize data transmission with server directly by transparent transmission function of LoRa gateway and LoRa module.
Data transparent transmission mode is suited to applications which don’t need to consider power consumption, such as smart city, smart agriculture, etc.
Support MQTT protocol, support USR Cloud function and provide multiple secondary development SDK to help user develop front-end page.
Ultra-low power consumption
In LoRa networking transmission system, WH-L101-C can realize super long standby time in low power consumption mode and power
consumption can reach 4 uA.
In LoRa networking transmission system, WH-L101-C can realize super long standby time in low power consumption mode and
power consumption can reach 4 uA.
Smart metering
Smart metering can be applied to meter water, electricity, gas, heat, etc. By LoRa wireless transmission system, cost is low and easy to implement.
In whole application, not only can receive accurate data, but also keep low power consumption.
Smart agriculture
By long communication distance, whole solution can realize accurate data transmission of status of agricultural irrigation, diseases and pests, fertilization, etc.
Solution can help to improve management level , reduce cost, know crops growth status timely and enhance economic performance.
Smoke detector
User can configure data index of node modules in every smoke detector. When environmental smoke value exceed this data index, smoke detector
will give alarm and module will in low power consumption at other times.
Oil field data monitoring
Can realize outdoor long-distance wireless transmission and monitor multiple oil fields to collect each oil field’s status.
This solution can help to manage and all-sided detection.
