The current vehicle monitoring applications

The data collected by the vehicle monitoring system in general audio and video information, GPS information, traffic information and alarm information. However, in the framework of the Intelligent Transportation planning, this information is not enough to fully rendered car monitoring system status, the future will be to add more vehicle information, such as: tire pressure information, the car dangerous goods detection information, car ticket information. driver status information, the car traffic information and car crowded is information.

With the acquisition system to continuously expand and expansion will inevitably lead to the increment of the amount of information, how can we optimize the information system, which requires the system to strengthen intelligence processing.

First, when information collection can be integrated with intelligent analysis algorithm, example: the video collection of information, can be monitored extra environmental information to filter out the scene, to increase the information efficiency, thereby saving storage space, save network bandwidth. Or directly from the video information to analyze the key data points, such as the status of the people off the state of the driver, or even the identity of their clients to identify the formation of secondary data storage and transmission.

Secondly, in the vast amounts of data, how can quickly find the information, which need to optimize the data search technology, cloud computing technology is the simultaneous development of the era, data search function easy, convenient, intelligent search algorithm for the protection of real-time system applications.

Wireless networks, has been the bottleneck of the vehicle monitoring system, front-end application development. 3G bandwidth for the continued expansion of the system application is also limited, as the OFDM (Orthogonal Frequency Division Multiplexing) technology, MIMO (Multiple Input Multiple Output), the development of smart antenna technology, you can expect the 4G era, but in view of administrative monopoly of the wireless communications industry, the 3G era I'm afraid there will be 5 to 10 years of use.

 Relative to the current vehicle monitoring applications, the needs of both real-time monitoring of the monitoring platform, there are high demands on quality, but the transmission bandwidth is limited. Front-end system, you can use the multi-stream technology to adapt to network bandwidth to meet the monitoring requirements. Multi-stream video capture, generate a different stream, for example: all the way high-definition stream of the full frame rate for local storage, a clear road signs and low frame rate stream real-time monitoring of network remote, all the way to HD low frame The rate of stream in the alarm or other critical moment for the remote data forensics.

At present, the vehicle monitoring system are led by different organizations and institutions, the implementation of various systems in the split between a lot of data information systems are not linked and can not share resources, which impede the development of system applications.Main product: in car camera   "Smart city", "intelligent transportation" policy planning, monitoring systems need to co-ordinate the integration, so to maximize resource utilization, can really carry out the intelligent traffic information service. This requires each vehicle monitoring platform data integration, providing services to a uniform standard, uniform format, and the need for an effective data management system, these data combined in an orderly way, the use of cloud computing technology, users and agencies to provide on-demand service.
