What are the advantages and disadvantages of turning on Bluetooth?

The benefits of turning on Bluetooth: 1. The power consumption is very low, which can ensure the operation of battery-powered devices, and it is very cheap. In terms of cost, it is very friendly to some low-cost devices; 2. It can manage data and The sound transmission delay is also relatively low, and the effect is very good when used on some devices that require large amounts of data to be transmitted. Disadvantages: The transmission distance is short, the rate is not as high as wifi, and some protocols between different devices are not compatible. If the data needs to be available uninterrupted, local data needs to be consistently recorded.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Bluetooth is a short-range wireless communication technology and an open global specification for wireless data and voice communications. It is based on low-cost short-range wireless connections and establishes a communication environment for fixed and mobile devices. A special short-range wireless technology connection.

The role of Bluetooth: It can exchange wireless information between a variety of devices, including mobile phones, PDAs, wireless headsets, laptops, related peripherals, etc. The use of Bluetooth technology can effectively simplify communication between mobile communication terminal devices and between devices and the Internet, thereby making data transmission faster and more efficient and broadening the path of wireless communication.

The advantages and disadvantages of Bluetooth communication technology

The advantage of Bluetooth technology is: its power consumption is very low, which can ensure the battery life The power supply equipment works and is very cheap. In terms of cost, it is still very friendly to some low-cost equipment. Bluetooth technology can also manage data and sound transmission at the same time, and the delay is relatively low. It is very effective when used on some devices that require large amounts of data to be transmitted.

The disadvantages of Bluetooth technology are mainly in the transmission distance and transmission rate. The distance is limited and the rate is not as high as wifi. Moreover, some protocols between different devices are not compatible. If the data needs to be uninterrupted Availability also requires consistent record keeping of local data.

Application of Bluetooth:

1. Bluetooth hands-free communication.

Use the mobile phone as the gateway to turn on the Bluetooth function and hands-free system of the mobile phone. As long as the mobile phone is within 10 meters of the hands-free system, it can automatically connect and control the microphone and audio system in the car to achieve full-duplex hands-free calls. The automotive hands-free application framework is used as the basis of Bluetooth hands-free communication technology, Bluetooth devices are well standardized, and Bluetooth function sets are assembled to achieve control of Bluetooth technology.

2. Car Bluetooth entertainment system.

Car Bluetooth entertainment system mainly includes USB technology, audio decoding technology, Bluetooth technology, etc. It integrates the above technologies and uses the car's internal microphones, speakers, etc.

3. Bluetooth vehicle remote status diagnosis.

The on-board diagnostic system mainly relies on Bluetooth remote technology to conduct vehicle maintenance in a timely manner, especially real-time monitoring of the vehicle engine, helping the vehicle to grasp the specific operating conditions of different functional modules at all times. Once the system is found to be operating abnormally, use the settings A good calculation method can accurately determine the cause and type of the fault, and upload the fault diagnosis code to the on-board operating system memory. Picking up is more convenient and faster.

4. Car Bluetooth anti-theft technology.

As the technology gradually matures, Bluetooth will be further improved in terms of wide application, safety of use, transmission accuracy, and transmission efficiency. Especially the application of Bluetooth anti-theft device. If the car is in a fortified state, the Bluetooth sensing function will automatically connect to the car owner’s mobile phone. Once the vehicle status changes or is stolen, an alarm will be automatically issued. The application of Bluetooth anti-theft technology provides safer safety for the car. environment.

5. Wireless monitoring of CNC machine tools by technicians.

The application of Bluetooth technology in CNC machine tools is mainly reflected in wireless monitoring. Bluetooth technology is used to install corresponding monitoring facilities to provide convenience for CNC machine tool users and at the same time maintain the safety of CNC machine tool production. Technicians use the Bluetooth monitoring equipment they carry to monitor and manage the operation of machine tools at any time, and promptly address production problems with CNC machine tools when they are discovered. In particular, the automatic monitoring capability implemented under the wireless data link can appropriately intervene in the operation of machine tools, such as stopping the spindle or system shutdown.

6. Detection of wear degree of parts.

The Bluetooth detection function is also reflected in the wear of industrial parts. Using Bluetooth detection software combined with wear detection materials to conduct experimental research, the wear resistance can be determined in detail, and Bluetooth wireless transmission can be used to transmit wear detection data in a timely manner. to relevant equipment, which performs intelligent analysis and informs technicians of the results.

7. Power output standardization.

Bluetooth technology is also very important in terms of power output in industrial production. The adjustment device uses Bluetooth technology to transmit production power changes and compares it with the standard operating power. If there is an abnormal power change, it will be adjusted in time and the adjustment data will be uploaded.

8. The Bluetooth monitoring system records the running status of the CNC system in real time and completely.

Bluetooth transmission equipment is the main component of the monitoring system. It records the operating status of the CNC system at any time, and transmits all fluctuations during the operation of the CNC system to the storage device. It uses the communication port to upload information to provide CNC production managers with More references.
