The Internet of Things is the interconnection of things and things, the most important of which is the network and intelligent core products. The development of Internet of Things technology has brought vitality and vitality to the Internet of Vehicles, and the development of Internet of Vehicle technology has continuously supplemented and spurred the Internet of Things technology.

We know that car networking is a category of IoT technology applications and one of the core applications of IoT technology. Vehicle network English abbreviated as "IOV" refers to the dynamic mobile communication system that communicates between vehicle and vehicle, vehicle and road, vehicle and people, vehicle and sensor equipment to realize communication between vehicle and public network. It can share information through vehicles and vehicles, vehicles and people, vehicles and roads, collect information on vehicles, roads and environment, and process, calculate, share and securely publish information collected from multiple sources on the information network platform. Provide effective guidance and supervision of vehicles according to different functional requirements, as well as provide professional multimedia and mobile Internet application services.
According to the documentation of the China Internet of Things Alliance, the Internet of Vehicles is a huge interactive network composed of information such as vehicle location, speed and route, driver information, road congestion and accident information, and various multimedia applications. Through GPS, RFID, sensors, camera image processing and other devices, the vehicle can complete the collection of its own environment and status information; through the Internet Bluetooth, 3G, WIFI, all vehicles can aggregate their various information transmission to the central processor and other Information exchange in the server; through computer technology, the information of these large vehicles can be analyzed and processed to calculate the optimal route of the vehicle, report the road condition in time and arrange the signal cycle.
According to authoritative media, "vehicle networking" will form a huge emerging industry. Internet of Things research experts and scholars conducted research and analysis on the Internet of Things industry. Experts pointed out the application of Internet of Things technology in all walks of life, and vehicle networking applications must be the most effective way to solve traffic problems.
Our IOV is an application of the Internet of Things in the automotive field. It is the only way for the actual development and deep development of the mobile Internet and the Internet of Things. It is a fusion technology for the future development of information communication, environmental protection, energy conservation and security.
At present, the domestic car network is in its infancy, and has not yet formed a better ecological supply chain. Some of the functional products, such as in-vehicle information services, such as car navigation, have formed a certain market scale and many investors. The target audience is also increasingly demanding in-vehicle information services. As a vertical application of the Internet of Things, the Internet of Vehicles has a very important position in the strategic emerging industry of the “Twelfth Five-Year Planâ€. It puts higher requirements on the functional requirements of the Internet of Vehicles application and requires more integration in the vehicle networking system. Functional requirements, such as: car four-channel audio and video hard disk recorder, car GPS navigator, car radio, car amplifier, bus station, car MP3/MP4, car reversing monitoring, car Bluetooth hands-free phone, car RFID IC card reading , car driving recorder, car 3G wireless Internet access, car WIFI hotspot, real-time traffic conditions....... and so on.
The use of the Internet of Vehicles system is the result of the deep integration of the new generation of information and communication technology and the automobile manufacturing industry. It is an important driving force in the transformation and upgrading of the automobile manufacturing and service industries and the transportation and service industry. It is also strengthening while maintaining the sustained growth of the national economy and economy. Social security, an important means of improving traffic efficiency and developing green energy conservation.
From a network perspective, the IOV system is a three-tier system of “end pipe cloudâ€.
The first layer (end system): the end system is the intelligent sensor of the car, which is responsible for collecting and acquiring the intelligent information of the vehicle, and sensing the driving state and environment; it is a ubiquitous communication terminal with in-vehicle communication, workshop communication and vehicle network communication; It is also a device that allows the car to have capabilities such as IOV addressing and network trusted identification.
The second layer (pipe system): to solve the interconnection between vehicles and vehicles (V2V), vehicles and roads (V2R), vehicles and networks (V2I), vehicles and people (V2H), to achieve vehicle self-organizing network and a variety of different Communication and roaming between networks ensures real-time, serviceability and network ubiquity in terms of function and performance. At the same time, it is the unification of public network and private network.
The third layer (cloud system): The Internet of Vehicles is a cloud-based vehicle operation information platform. Its ecological chain includes ITS, logistics, passenger and freight, hazardous vehicles, auto repair auto parts, car rental, enterprise vehicle management, and automobiles. Manufacturers, 4S stores, vehicle management, insurance, emergency rescue, mobile Internet, etc., are the convergence of multi-source and massive information, so cloud computing functions such as virtualization, security authentication, real-time interaction, mass storage, etc. are needed, and the application system is also around the vehicle. A composite system of data aggregation, calculation, scheduling, monitoring, management and application.
Now GPS+GPRS is not really a car network, nor is it an Internet of Things. It is just a combination of technologies. At present, most ITS experiments and IOV concepts in China are based on this technology.
Shanghai Chenhan Electronics has been engaged in the research and development of automotive electronics and IoT applications for many years. It has successfully made the third generation of IOV system products, including the functions that have reached all the functions in the current domestic car networking system, such as: Car four-channel audio and video hard disk recorder, car GPS navigator, car radio, car amplifier, bus station, car MP3/MP4, car reversing monitoring, car Bluetooth hands-free phone, car RFID IC card reader, car driving recorder , car 3G wireless Internet access, car WIFI hotspot, real-time road conditions. With the development of Internet of Things technology and network technology, as well as the development of smart core applications and related industries, the functions of Chenhan car networking system will be expanded, and the trend of the industry development and fresh blood will be constantly pursued.
Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work specifically with computers, while others can be hooked up to any type of sound system. Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener.
Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver. This input may be either in analog or digital form. Analog speakers simply amplify the analog electromagnetic waves into sound waves. Since sound waves are produced in analog form, digital speakers must first convert the digital input to an analog signal, then generate the sound waves.
The sound produced by speakers is defined by frequency and amplitude. The frequency determines how high or low the pitch of the sound is. For example, a soprano singer's voice produces high frequency sound waves, while a bass guitar or kick drum generates sounds in the low frequency range. A Speaker System's ability to accurately reproduce sound frequencies is a good indicator of how clear the audio will be. Many speakers include multiple Speaker cones for different frequency ranges, which helps produce more accurate sounds for each range. Two-way speakers typically have a tweeter and a mid-range speaker, while three-way speakers have a tweeter, mid-range speaker, and subwoofer.
