Smart lighting technology agreement a hundred schools of thought contend, the next trend is it!

All along, the domestic smart lighting market agreement is the existence of diversified differentiation. ZigBee, Bluetooth, WiFi, 2.4G and other native advantages, but also have a short board.

Bluetooth 5 standard will be released at the end of this year, and contains a comprehensive Bluetooth Mesh technology; MacBee technology alliance was formally established, the upcoming release of the first edition of MacBee ZigBee and EnOcean technical white paper; energy collection technology combine to create a dual scheme of these new trends you can not know.

Various agreements in the domestic market for their respective camps

ZigBee is now a mature stage, driven by PHILPS, OSRAM, more and more mainstream manufacturers, but the drawback is not the use of intelligent mobile phone direct control, also need to pass additional gateway.

Bluetooth and ZigBee compared to the difference is not large, but also occupy some of the market. WiFi this protocol is used in intelligent lighting, the stability and connectivity of the connection to be solved. Due to its short development cycle and low cost, 2.4G has become the preference of many small and medium-sized lighting manufacturers, but it belongs to the private agreement, there will be problems in the interconnection, contrary to the future standardization process.

When choosing an agreement, many factors should be taken into consideration, such as technical maturity, design experience, cost, stability, and the use of scenarios. A variety of agreements to kill each other, who is more in the future market?

"I think Bluetooth will have more advantages over ZigBee in the future. "He flew Wulian chairman Han Xingcheng said," this is related to our company, we do 2.4G chip, ZigBee is a standard protocol, in addition, there is not much difference between ZigBee and 2.4G, it has great advantages in power distance. Bluetooth can be connected directly to the network, you do not need to add the gateway can be docked, in addition, it can be connected directly to the phone, easy to use, the cost is not higher than ZigBee. ZigBee to control the use of mobile phones to bridge, the future will be able to connect directly with the phone will have a strong vitality. "

The Bluetooth 5 standard will be published at the end of this year or the beginning of 2017, the bandwidth will be higher, can support the control instruction and the sensor data is more complex, the receiving sensitivity of the transmission distance, the chip also has the very big promotion, enhance the BLE network coverage ability will be greatly enhanced. When the single frame data of the sensor is more than 20 bytes, it will be easy to solve after the Bluetooth 5 specification. Bluetooth 5 will fully contain Bluetooth Mesh technology. In the recently held the third China IOT conference, Song Shuo, general manager of the joint venture from the sharp core said.

Bluetooth Mesh technology was first proposed and released by the British CSR in 2014, after the acquisition of Qualcomm CSR. At present, Shanghai Thai Ling and Qualcomm is able to provide stable chips on the Bluetooth Mesh technology company.

What are the advantages of Mesh technology, so that everyone applauded?

(1) basic lighting control. Smart phones can control the lights, sensors, and other related devices directly through the Bluetooth data channel. Direct control of the lights on and off, brightness adjustment, color temperature adjustment, RGB adjustment, in the regulation of brightness and color temperature in the process of overcoming the lights flicker, so that the adjustment process of linear and smooth. Groups of lights can be grouped and overlapping between groups. Group for supporting multiple mobile phones to simultaneously control multiple lamps. This technology is now very mature.

(2) the application of super gateway. Relying on WiFi-MeshSuperGateway (Qualcomm QCA4531WIFI module +CSR8811BLE module), you can achieve the remote control of lighting equipment and other sensors and electrical equipment through the internet. Similarly, the Internet can be completed through the basic lighting control, other equipment will be uploaded to the cloud. Extended extended ZigBee module. The OTA can be upgraded by SuperGateway for multiple lamps and multiple devices.

(3) to access various sensors in the data network. The Mesh technology allows the sensor to interact directly with the light and other devices. Sensor data can be transferred to the APP or the Internet (cloud) via BLEMesh or wifiMesh super gateway. It has a relatively high degree of infrared sensor, magnetometer, temperature sensor, vibration sensor.

(4) location, trajectory description and navigation applications in buildings. Relying on BLE broadcast technology, combined with the electronic map technology, in the building to achieve location based applications (LBS). In the room, the Mesh bulb can be used as a GPS satellite in the building. The positioning accuracy can reach 0.5 meters. This indoor positioning technology will be a new direction of development, to fill the gaps in indoor positioning, will bring new applications and business models.

Song Shuo also mentioned that the future of Mesh technology has two directions. First, in the absence of interference or as little as possible to intervene in the case of the lighting system to meet the needs of use, and to achieve energy saving and reliable. Mesh technology all the nodes of the lamp can be interconnected with the phone. Two is the use of Bluetooth Mesh network can become a smart home of non video data transmission based on the data network. Relying on the advantages of node lighting everywhere, let Mesh network coverage more smoothly, access security equipment and other electrical equipment magnetic sensor. "

Bluetooth Mesh will become intelligent lighting big brother? We are not satisfied with MacBee!

From the development and application of the agreement has its original intention. Bluetooth is born for the headset, ZigBee is born for M2M, MacBee for the family networking. Galaxy Fengyun Dong
