Bluetooth application in industrial internet of things
The scale of IoT applications is becoming more and more mature, but in our general perception, IoT applications have been applied in large scale in the fields of smart home, car networking, personal consumer electronics, and mobile article management. In fact, far more than this, the Internet of Things is The industry also plays a huge role. In 2010, Bluetooth low-power technology began to emerge in various fields, and with this button-sized battery power, it can run in the IoT products for several years. This low-power feature is attractive in industrial applications, and it also makes industrial products easier to use, and control and monitoring becomes more convenient.
Today, smart phones and tablets are equipped with smart Bluetooth technology. Without the need for a gateway, industrial devices can communicate directly with smartphones or tablets, thus avoiding complex human-machine operations. At the same time, we can also Monitor the temperature of the device, the activity of the motor, etc. via a smartphone or tablet, and also alert when the parts of the device need to be repaired or replaced. In addition, because smart Bluetooth eliminates the need for communication cables between devices and devices, it can save a lot of money for the factory. Smart Bluetooth can also be placed in harsh environments to protect the product from temperature and dust.
The low-power nature of Bluetooth has made Bluetooth a unique value in many new areas, from consumer electronics to medical electronics, from smart homes to industrial applications. Bluetooth low energy is playing an important role in the IoT market. This feature is also the best choice for sensors, and IoT and cloud connectivity come naturally, enabling Bluetooth devices to connect to anything and connect to the network (read or download information from the cloud).
In 2010, Bluetooth 4.0 was released, and Bluetooth became an advantage with low-power technology. In 2016, Bluetooth 5 was released. Compared with the previous version, not only the transmission distance has increased by more than 4 times, but also the transmission speed has doubled at the same time, which means that the transmission between devices can save half of the time (including uploading). And download), which is what we often say to get twice the result with half the effort.
In particular, in July of this year, SIG announced the launch of a new Mesh function, providing multi-to-many device transmission, and greatly improving the communication performance of building a wide range of network coverage, suitable for building automation, wireless sensor networks, industrial applications, etc. An Internet of Things solution that transmits thousands of devices in a reliable and secure environment.
The Bluetooth advantage of Mesh network is first of all reliability, self-healing ability based on Bluetooth technology can avoid single point of failure; secondly, it is good scalability, can support tens of thousands of nodes, provide industrial-grade performance, realize industrial networking equipment scale The breakthrough is again security. In addition to the 128-bit AES encryption of data, Bluetooth technology also adopts multiple levels of protection against encryption.
As a professional Bluetooth module supplier and Bluetooth solution company, Shengrun Technology can provide a selection of industrial-grade intelligent Bluetooth modules, including the recent HY-40R201P and HY-40R204P, which is a high reliability and low power consumption. The Bluetooth 4.2 module, with the TI CC2640R2F microcontroller (MCU), supports the Bluetooth 4.2 BLE protocol and supports Bluetooth 5, and can operate over a wide temperature range of -40 to 85 degrees Celsius. It is also far ahead in the industry standards, and has passed BQB, FCC, CE, RoHS and other certifications.
Mobile phones and earphones have become necessities in our lives. How many people feel restless when they don`t have a mobile phone around. The mobile phone gives us a great sense of security to a certain extent, and its additional earphones also have such a function. . Wear headphones when you don`t want to talk; when you don`t want to listen to others, you wear headphones; when you don`t want to be harassed in an unfamiliar environment, you can play your favorite songs, be happy or sad, and enjoy your little universe most comfortable. There are now a variety of earphones on the market for people to choose from. From the original wired earphones to the current wireless Bluetooth earphones, they are more and more in line with people's requirements, and the sound quality and noise reduction are also constantly improving.
If you want to get a sports headset (sports scene) or a true wireless tws true wireless Bluetooth headset, what you expect from him is that it has the ability to withstand the test of different environments, wear it steadily, and have a long battery life, or it may be out of the street. Appearance, excellent sound quality, stable connection, friends who have certain requirements for sound quality and low requirements for noise reduction. You can take a look our earbuds.
