Internet of things is a very large concept, emphasizing that everything accesses the Internet of things and can communicate with each other wirelessly. The subdivision covers smart cities, smart healthcare, smart industries, smart agriculture and smart buildings. However, for various reasons, the construction of a smart city is still in its infancy. With the development of intelligent transportation systems and power grid systems, many enterprises have started to adopt wireless monitoring, detection and control technologies in the agricultural, industrial and construction markets. Professional sensors and network equipment. Internet of Things is also called the third wave of the development of the world information industry after computers and the Internet. It is an application development of the Internet. Innovation is the core of the development of Internet of Things. Wireless and sensing technologies have played an important role in the Internet of Things era. Character. In view of this, the reporter interviewed Xu Hong Yue, a veteran professional, to explore wireless + sensor design solutions for the Internet of Things era. Sensing Wireless + Sensing Design Accelerates everything Xu Hong said the industry, focusing on the consumer-level Internet of Things market, which belongs to intelligent building intelligent lighting and smart home, intelligent building is focused on wireless and automatic control, which can not do without sensing and wireless communication technology. At the same time, Murata is a veteran supplier of electronic components, wireless modules and sensors, and has its own strong RF and sensor technology. In the field of consumer-grade IoT, these two types of products will be the main promotion directions. Wireless + sensor network connection program In simple terms refers to the sensor + wireless network connection, that is, in a sensor network, the sensor to obtain environmental parameters, and then uploaded to the network through the wireless module. Software supports four aspects: Sensor algorithm 2. Sensor - wireless module data interface; Wireless protocol 4. Network Control Protocol and Software (including Gateway, Routing, App, etc.). Xu Hong Yue pointed out that the application of sensor networks are diverse. Such as the more familiar smart home system, you can door / window magnetic sensor, the human body infrared sensor system composed of home monitoring, when the owner set the anti-theft / go out mode, if it detects the doors and windows are open, or someone passed the signal, the system will trigger Call the police. On the one hand through the cell monitoring system to inform security guards, on the other hand remotely notify the owner via the Internet. For another example, the environmental control system of warehouse, factory and agricultural greenhouses can automatically adjust the internal environment with the facilities such as temperature and humidity sensors, infrared sensors, ambient light sensors, soil sensors, air conditioners, exhaust fans and the like, and feedback the environmental parameters to the host in real time Can not do without wireless + sensing solution. Xu Hong Yue said that a major feature of the Internet of Things is interconnection, another feature is the perception, so wireless + sensing can be applied to almost all areas of the Internet of things. Wireless technology to accelerate home intelligent Currently in the lighting market, many manufacturers have begun to explore intelligent lighting, and many new office buildings, shopping malls, airport projects have joined the wireless lighting system. For a commercial building, the energy consumption of traditional lighting system accounts for more than half of the total building energy consumption, and now the public advocate energy saving and emission reduction. In order to meet the green building standard, the demand for intelligent lighting system in commercial buildings is more pressing. Xu Hong said this more, Murata launched a commercial lighting Zigbee wireless lighting control program, the corresponding products are: 1) The Zigbee module can be connected with the LED driver power supply and the sensor, and can wirelessly adjust the light or obtain the sensor data; 2) Zigbee dimmer, the principle is the relay controlled by Zigbee module can output AC / 0-10V DC / PWM three dimming signal. Any LED driver that supports these three dimming interfaces can be connected to a Zigbee dimmer. Lighting customers do not need to make any design changes to the radio, simply connect the corresponding interface to a dimmer, so there is no need to change the customer A product design, greatly reducing the user's product development cycle and cost. 3) gateway 4) Software as part of the network layer. Intelligent lighting as part of the smart home system, network nodes in the interoperability stability of the most important. Xu Hong Yue said that for now, can form a Mesh network (mesh structure) Zigbee more applications in the smart home system, smart home company if you want to develop a complete system, rather than a single product, then generally use Zigbee to develop, Wi-Fi and Bluetooth are star networks, suitable for a single product, such as Wi-Fi / Bluetooth speakers, appliances, air cleaners and so on. For the home market, Xu Hong Yue said Murata can provide a variety of SoC-based Wi-Fi, Bluetooth, Zigbee module. For smart home makers, Murata is also based on the Zigbee solution. For home appliance manufacturers, Murata has a Hostless WiFi (embedded WiFi) serial port module specifically for home appliances with a built-in MCU. In terms of Bluetooth, the traditional Bluetooth is not suitable for smart home or intelligent lighting system. Last year, the Bluetooth Alliance developed the BLE Mesh protocol. Murata introduced a Bluetooth module that supports BLE Mesh, but the market is still waiting to see.
