1, Bluetooth hands-free communication
Turn on the Bluetooth function of the mobile phone with the mobile phone as the gateway. As long as the mobile phone is within the range of the car handsfree system 10 meter, it can automatically connect and control the microphone and sound system in the car to realize full-duplex handsfree call.
2, car Bluetooth entertainment system
Car Bluetooth entertainment system mainly includes USB technology, audio decoding technology, Bluetooth technology and so on. It uses the microphone and stereo in the car to play all kinds of audio and phone books stored in the USB flash drive, and also adds pop music and other playing functions. Connecting the network in the in-vehicle system based on CAN can realize the operation of the in-vehicle infotainment system. At the same time, it also retains the scalability of the system.
3, car Bluetooth anti-theft technology
If the car is in a fortified state, the Bluetooth sensor function will automatically connect to the owner's mobile phone, and once the car state changes or is stolen, it will automatically call the police. The application of Bluetooth anti-theft technology provides a safer environment for cars.
Second, the application in industrial production
1. Wireless monitoring of CNC machine tools by technicians
Using Bluetooth technology to install the corresponding monitoring facilities provides convenience for the production users of CNC machine tools, and also maintains the safety of CNC machine tools. Technicians can monitor and manage the operation of machine tools at any time according to the Bluetooth monitoring equipment they carry with them, and solve the production problems of CNC machine tools in time.
2, parts wear degree detection
Using Bluetooth detection software combined with wear detection materials to carry out experimental research, we can use Bluetooth wireless transmission to transmit the data of wear detection degree to relevant equipment in time, and the relevant equipment will make intelligent analysis and inform technicians of the results.
Third, the application in medical field.
1, diagnosis result transmission
By means of Bluetooth transmission equipment, the hospital diagnosis results are transmitted to the memory in time. The application of Bluetooth stethoscope and Bluetooth transmission itself have lower power consumption and faster transmission speed. Therefore, using electronic equipment to transmit the diagnosis results in time can improve the efficiency of hospital diagnosis and ensure the accuracy of the diagnosis results.
2. Ward monitoring
The application of Bluetooth technology in hospital ward monitoring is mainly embodied in sickbed terminal equipment and ward controller. The main control computer is used to upload the number of sickbed terminal equipment and the basic hospitalization information of patients, and inpatients are equipped with sickbed terminal equipment. Once the patient has any emergency, the sickbed terminal equipment sends a signal, and Bluetooth technology transmits it to the ward controller in a wireless way.
Extended data:
principle
Bluetooth can realize short-distance data exchange among fixed equipment, mobile equipment and personal local area network of buildings, and can connect multiple devices, thus overcoming the problem of data synchronization. Common Bluetooth devices such as computers and mobile phones. Bluetooth products include Bluetooth modules, which support Bluetooth wireless connection and software applications.
Bluetooth device connection must be paired within a certain range, which can accommodate no more than 8 devices at most. The Bluetooth device has been successfully connected. There is only one master device, and there can be multiple slave devices. TDMA structure and multi-level network structure are adopted, and frequency hopping technology and wireless technology are applied technically.
