Blue Ocean Voice targets the current stageLoRa technologyAfter continuous optimization by the R&D team,innovationUpgrade and create a comprehensive performance leap, with unlimited connectivity within kilometers,通信更The main points for achieving stability and zero latency in data transmission are as follows:

1. Wide coverage

Difficulties:

In the environment of office buildings and obstacles such as rigid cement, wireless signals are easily affected by factors such as building structure and materials, resulting in signal attenuation and limited coverage.

Innovation breakthrough:

Adopting high powerLora module: Choose a Lora module with high transmission power, excellent spectral characteristics, very small harmonics, and can effectively penetrate obstacles such as buildings.

Enhanced antenna design: By using directional antennas or high gain antennas, the directional transmission capability and coverage range of signals can be improved through reasonable antenna layout and design.

Network planning optimization: Conduct detailed network planning, including base station location selection, antenna height adjustment, etc., to maximize signal coverage.

2. Multiple up and down channels:

Supporting multi-channel communication can improve network throughput and stability, but it requires addressing spectrum management and interference issues to ensure effective coordination and resource allocation between channels.

Intelligent Spectrum Management: Implement intelligent spectrum management strategies, dynamically select available channels, and reduce spectrum interference and congestion.

Multi channel parallel processing: Design support for multi-channel parallel processingLora gateway improves data transmission efficiency and system capacity.

3. Support synchronous communication and random communication (low-power terminal devices)

Difficulties:

Synchronous communication and random communication require high synchronization and real-time performance of the system, as well as low-power design.

Innovation breakthrough:

Adaptive scheduling algorithm: Develop adaptive scheduling algorithms that dynamically adjust communication methods and times based on the needs of terminal devices and current network conditions to achieve efficient integration of synchronous and random communication.

Low power design: optimizationThe hardware and software design of Lora socket adopts low-power chips and algorithms to reduce unnecessary energy consumption.

4. Stable communication, real-time monitoring of synchronous and random channel terminal device data changes

Difficulties:

Real time monitoring of data changes in terminal devices requires efficient data collection and transmission mechanisms, while ensuring communication stability.

Innovation breakthrough:

Data compression and encoding: Using efficient data compression and encoding techniques to reduce data transmission volume and improve transmission efficiency.

Real time monitoring and feedback mechanism: Establish a real-time monitoring and feedback mechanism to monitor the data changes of terminal devices in real time, and throughThe Lora gateway promptly transmits data to the server.

5. Low latency communication:

Especially in long-distance communication, the delay of controlling up and down data communication should not exceed3 seconds, it is necessary to optimize the protocol stack and network management to ensure timely data exchange and response.

6. The gateway can connect to terminal devices with multiple communication methods, and the communication methods are diversified

Difficulties:

Terminal devices with different communication methods have differences in protocols, interfaces, and other aspects, requiring complex adaptation work to achieve docking.

Innovation breakthrough:

Modular design: Adopting the modular design concept, the gateway is designed as a pluggable module structure, which facilitates the adaptation and expansion of different communication methods.

Protocol conversion and adaptation: Develop efficient protocol conversion and adaptation software to achieve seamless integration between different communication methods.

Currently, Blue Ocean VoiceLoRaThere are three solutions for connecting smart sockets to servers:

1) Gateway free, WiFi direct connection to router hotspot via socket, uploading data to server;

2) Bluetooth socket+gateway (Ethernet+WIFI+Bluetooth), the socket serves as the slave device of the gateway and reports the collected data to the gateway. The gateway is connected to the backend or local server through a network cable;

3) LoRa socket+LoRa gateway (LoRa wide area network+Ethernet+WIFI+Bluetooth), the LoRa socket is responsible for collecting electricity and current data, and reporting the collected data to the LoRa gateway, which is connected to the backend or local server through a network cable;

And in order to deeply connect with the high-end customization needs of intelligent ecological projects such as smart parks, smart factories, smart businesses, smart hospitals, smart warehousing and logistics, and smart offices, innovative open interface protocols are used, and backend system integration is supported:

1) Can provide TCP protocol, MQTT protocol interface documentation, and socket hardware interface docking with customer backend;

2) Our cloud server can provide socket data forwarding;

3) Provide SDK or backend system software localization deployment services.
