Vehicles are widely used and highly developed tools. The main role of the vehicle at present is transportation. Although the speed is fast, if you encounter a sudden incident in the distance during transportation, you will suddenly be in a blind state. You have to wait for the scene to get the first hand data. Although sometimes this is only delayed for a few hours or minutes, in many cases, such as traffic disputes, major accidents, unexpected disasters, etc., because of the lack of understanding of the scene, it is often impossible to take timely countermeasures, resulting in the loss of losses cannot be contained as quickly as possible Very passive.
In daily work, there are many situations that do not cause major losses, but they also want to be more efficient. For example, when an enterprise manager goes out in a car, he hopes to maintain communication with the enterprise at any time to facilitate management. Smoothly. Although there are mobile phones that can be used now, the screens and entities that are too small are mainly suitable for simple personal communication, but not for the complex communication requirements of enterprises or groups.
A further requirement is how to coordinate the concerted action of large-scale vehicle groups. If a car group needs to go out at the same time, how to coordinate the actions of these vehicles? Such as police operations, or large construction sites. The cooperative command mechanism can be placed in the rear or on the vehicle. No matter where they are, they are faced with the problem of how to timely understand the changing scene. It can be believed that there are some expensive special vehicles with such technical means, but because of their high cost, they cannot meet a wide range of social needs.
If the above problems are solved, the vehicle can be not only a means of transportation, but also a powerful information carrier. Personnel can either sit in fixed buildings or rely on vehicles for uninterrupted work at any time. Synergy will be doubled due to mobility.

Second, the use of car real-time video
The key to solving these problems is the ability to equip vehicles with real-time video that can be communicated. Real-time is the essential difference from video file download. Video download is a slower video application, so it is mainly used for entertainment. Many surveillance videos are also real-time videos, but due to the purpose of surveillance, the requirements for the video are lower and can be seen almost clearly. Can not meet the needs of communication.
Car real-time video can be used to play 3 roles.
1. Video capture. The on-board video capture can transmit the video back to the collaborative organization in real time through the wireless network, which is convenient for obtaining the first-hand real situation.
2. Video communication. Vehicles can communicate with each other through wireless networks and networked organizations at any time, exchange information with each other, and express each other's requirements.
3. Video collaborative command. The coordinated command here does not refer to the general management function, because the coordination caused by the management function can be completed by general video communication. Collaboration here refers to the installation of multiple video communication devices on the vehicle, which can send and receive real-time video of many vehicles, and organize distributed video sources into a centralized virtual environment, thereby forming a mobile real-time collaborative command flagship vehicle.
Third, the difference between on-board real-time video equipment and on-board computer
Is it right to use a car computer for car real-time video equipment? Broadly speaking, with the development of chip technology and software technology, smart devices based on single chip computers are gradually moving closer to and converging with computers. Just like the current mobile phone, it is not only used to make calls and send text messages, but also to surf the Internet, and video conversations are already very much like a microcomputer. However, due to the characteristics of mobile devices, volume and mobility requirements, in fact, there are still big differences. When vehicle-mounted equipment is officially a vehicle component, it needs to meet the requirements of miniaturization, seismic resistance, and standardization. For engineering vehicles used in construction and engineering, the earthquake resistance alone is probably a very difficult professional topic.
Vehicle real-time video equipment also has the problem of requiring standardization. Only automobile manufacturers can be equipped with unified equipment when they leave the factory, so that buyers can quickly associate vehicles with simple configuration during use to form a collaborative The internet.
Automobile design can also be designed as a detachable standard peripheral interface to facilitate the addition of mobile devices.
4. Problems that need to be solved for real-time video equipment in vehicles
Vehicle real-time video equipment should solve the following problems.
1. The communication means and equipment of the equipment. Use wifi, satellite line, short wave mode, or 3G channel, or other special programs. Choose some of them to form the basis of communication between vehicles.
2. The operating system of the device. Wince, linux or other embedded operating systems choose the operating system suitable for constructing complex video applications as the software foundation.
3. Software for real-time video communication. Qingyang video conference can support video communication of mobile devices running winCe6.
4. The hardware foundation of the equipment. Use chips such as arm and other hardware problems.
5. Integration design issues of mobile devices and vehicles.
6. Security guarantee for collaborative communication. Let the information equipment of the vehicle have the ability to establish VPN.
Five, the important time to join the car video equipment
Why is it now an important time for vehicles to join in-vehicle video equipment?
Automobile companies can design a video communication system by themselves, such as moving a TV system into a vehicle. It is technically possible. But there is a major problem that the cost of production and development is very high.
Expensive equipment development and production costs can only be reduced to unimaginable proportions through highly developed global industrial cooperation. In the era of global industrial cooperation, the law of value is contrary to ordinary feelings, the value is getting higher and higher, but the price has not risen, and it is very cheap. For example, intel chips, the computing power of a common intel chip may not be realized by billions of investment a few decades ago, but now only a few hundred yuan. This is the benefit of global market cooperation. Miniaturized mobile devices used to be handled by specialized single-chip microcomputers. Specialization meant that they could not rely on a wider market and technical cooperation to share costs. Microsoft and other development agencies finally designed winCe.linux and other embedded operating systems to make the embedded system get rid of the state of specialization and partial doors. With the development of chips such as arm, it can finally support more complex video applications. This means that low-cost, high-performance mobile devices can finally support rich industrial applications.
Another important reason is the development of wireless technology applications. Vehicle video communication must rely on the development of wireless communication. The construction of wireless communication channels is also heavily invested. Now wifi provides universal wireless local area access, and 3G provides universal wide area network access. So that vehicles do not necessarily need to establish a separate communication channel, you can use mobile video. The development of wifi and 3G in China is not too long.

Therefore, at this stage, it is the right time to join in-vehicle video equipment.
6. A new era of real-time video applications in vehicles
Large-scale introduction of in-vehicle video equipment will inevitably lead to changes in vehicle applications, and will also introduce a large number of novel technologies.
After the introduction of mobile video equipment, the vehicle will quickly change the isolation of the vehicle and turn the vehicle into a node in a network of various sizes. Using dedicated communication channels, vehicles can be connected into a private network; or through a VPN, a virtual enterprise internal network can be established. In this virtual internal network, you can engage in safe corporate activities.
This will be a new era of vehicle applications.
