The vehicle operation monitoring system has long been the focus of the development of intelligent public transportation. Internationally, systems such as IVHS in the United States and VICS in Japan have realized the management and information services of intelligent public transportation by establishing effective information communication between vehicles and roads. And 3G/4G and other wireless technologies have also been applied in the intelligent management of transportation, such as intelligent bus positioning management and signal priority, operation scheduling management, real-time vehicle status and environmental information collection, etc. have achieved certain application results.
Under the background of the development of communication through science and technology, the transportation industry is undergoing an unprecedented major transformation. Traditional manual scheduling, semi-automatic scheduling, and pure GPS/BD scheduling will gradually be replaced by intelligent scheduling. The wide application of big data mining technologies based on the Internet of Vehicles and OBD can not only change the function and informatization degree of in-vehicle video terminals, and form an emerging industry, but will also innovate transportation management and service methods, and help the transformation and upgrading of the transportation industry. play an important supporting role.
In the construction of intelligent transportation system, “high-definition” has become an inevitable development trend. The entire video surveillance system has been transformed from a “visible” video security system to a “clearly seen” high-definition networking system, and following the principle of “build for use, use for war”, the intelligentization of “see clearly” has begun. , System construction of business integration applications.
High-definition is not only the application of a single high-definition technology, but starts from the actual business application requirements of intelligent transportation, which can adapt to the needs of all cities in the city to control the high-definition image quality. The control surface of the entire city is in a complex and diverse application “ecological environment”. Therefore, the construction of high-definition intelligent transportation systems needs to choose suitable high-definition solutions according to the different characteristics of different application scenarios. High-definition vehicle video recording is bound to be the future. a development direction.
Due to the large amount of car video data and limited local storage space, in order to completely back up all the video, we must use cloud storage.
Cloud storage is a new concept extended and developed from the concept of cloud computing. A system that works together through application software to provide data storage and business access functions to the outside world. Cloud storage is a cloud computing system with data storage and management as its core. Simply put, cloud storage is an emerging solution to put stored video resources on the cloud for human access. Users can connect to the cloud through any networkable device at any time, anywhere, and access data conveniently. The advantages are as follows:
Cost saving: The biggest feature of cloud storage in the short and long term is that it can reduce costs.
Better backup of local data and remote processing of daily data: In the previous storage system management of on-board terminals, managers needed to face different storage devices, and devices from different manufacturers had different management interfaces, which made managers need to understand each The work of the usage status (capacity, load, etc.) of each storage medium is complex and heavy. Moreover, in the vehicle vibration environment, the traditional storage medium hard disk is easily damaged, resulting in data loss, while cloud storage does not. If the hard disk is damaged, the data will be automatically migrated to other hard disks, which greatly reduces the work of management personnel burden.
With the rapid development of technology, the vehicle video surveillance system is also constantly developing, bringing a more convenient experience for managers. Combined with the characteristic needs of the industry, it creates a more intimate industry application for users.
