Feature one: USR private protocol with networking to make use safe, reliable, flexible and convenient

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.

 

 LoRa Module

Feature two: Multiple work modes provide wide application field and adopt TDM technology which has low interference

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. 

Work mode one: Node active reporting mode

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.

LoRa Module

Work mode two: Polling waking mode

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

 

Work mode three: Data transparent transmission mode

 

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.

LoRa Module

 

Feature three: Provide MQTT/Socket protocol and support Cloud development

 

Support MQTT protocol, support USR Cloud function and provide multiple secondary development SDK to help user develop front-end page.

                                                                                        Applications

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.

LoRa Module

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.

LoRa Module

 

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.

LoRa Module

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.
