Bluetooth technology advantage
The biggest advantage of smart devices is not only to collect data, but also to achieve linkage and group control between devices.
Collecting data is to discover better modes through cloud computing, such as how to save power, arrange maintenance and other work more reasonably, and the interaction between terminal devices is the most important, for example, the biggest function of smart sockets is to remotely control power failure. If it is linked with surrounding temperature, fire alarm and other monitoring equipment, the effect of linked group control can be achieved.
This is the most common application of edge computing in the Internet of Things, and they are all based on Bluetooth technology.
Bluetooth technology featurea
- The amount of data to be transmitted is large, and it is only the second child with the ability of Wi-Fi in this respect. This kind of application is very popular on speakers and earphones. For smart devices, it is very convenient for on-site personnel to directly read device information through mobile phones.
- It can build a mesh network by itself, at least to ensure that the network can be kept open between Bluetooth devices in the event of a disconnection. In the event of a fire or other accident, it is difficult for us to ensure that the existing wireless network is normal. Bluetooth is equivalent to two Heavy insurance.
- There is also a positioning function. If it is a larger device, the accuracy requirements are actually not high. Bluetooth positioning is basically within one meter, which fully meets the requirements. More accurate AOA positioning can help positioning more accurately. The key is that there is basically no additional cost.
Bluetooth technology and smart home
Many devices now integrate Bluetooth positioning beacons and passive indoor antennas to deeply integrate positioning networks, the Internet of Things, and communication networks. On the one hand, the communication capabilities between Bluetooth devices are strengthened, and indoor sensors will collect information (for example: Temperature and humidity value, smoke alarm) are sent out in the form of a broadcast packet, the passive room antenna built-in Bluetooth beacon receives the broadcast packet information sent by the surrounding Bluetooth sensors, and then transmits it back to the Bluetooth gateway and Bluetooth gateway through the power splitter/coupler Upload the sensor data to the cloud platform for data analysis.
On the other hand, it can also realize the functions of indoor weak coverage analysis and indoor accurate positioning.
If companies can use Bluetooth technology more, including smart lighting systems, smart sockets, smart locks, electronic tags, temperature control devices, smart cameras, etc., all use Bluetooth modules, which is equivalent to building Bluetooth wireless on the basis of the original Wi-Fi. The network has realized on-site control of these devices in the case of network disconnection.
Bluetooth device ad hoc networks have been widely used in smart lighting systems. For security systems, linking smart sockets with smart temperature and humidity and smoke alarms is another layer of better protection for assets.
