Car DVR’s Intelligent Character Shows In the Hostile Vehicle Environment

    Nowadays, Car DVR has gone through a lot of years. And after several years of development, indeed technically made a lot of improvement. However, the current application from the field of view, it seems that technology is far less optimistic. It also requires car DVR The function to be in the future development, further closer to the daily needs of the civilian, at the same time, the product of intelligent direction of increasingly prevalent.

Car DVR Need to deal with the harsh environment inside the car

It is understood that, in order to ensure that buses can still achieve smooth running store, manufacturers are on-board DVR Enhanced technologies include shock, regulated current, heat, wireless transmission. Perfect integration of these technologies are designed to further enhance the Car DVR Storage stability.

Power Design: To ensure Car DVR is working properly, we must first ensure that the power strip output power stability. Narrow voltage at a fixed environment, due to the input voltage and current basically stable, moreover from the electrical side, the output power of decision to the input power, so the power aspects of ordinary DVR can only need an adapter, an adapter is nothing less than a transformer plus a filter circuit, plus a little bit of conscience protection circuit protection circuit heartless not loaded, cheap Well, so ordinary DVR costs and maintenance costs are relatively low.

Future Car DVR To be more intelligent

But for Car DVR, the first thing to do is dynamic voltage and current narrowing refined. How to ensure the normal operation of the vehicle-mounted DVR stable voltage and current is very important, but on the other hand, the input power of the device is fixed by W = U * I Shows the voltage change when the current is changing, the change direction of the voltage with the current always opposite. So if you start doing the lower voltage, then the relative starting current will increase. The macro is so simple, but this feature can be stable and to ensure normal operation of equipment may need to be done on it, and the first is designed to protect the circuit, you know Car DVR power board Within hours, hundreds of times to withstand the impact, the protection circuit to do well, ranging from the power board is damaged, while in the breakdown of the power supply board directly burned motherboard.

Seismic design: seismic design Car DVR is very important, that the white is actually how to protect the hard drive. Because the current hard drives are mechanical shaft drives, only a few microns from the read-write head and the disk, if with the naked eye, the read-write head is attached to the disk, but even if you do not understand the hard drive you should understand that 5400 Hard disk to rotate at least every second turn 90 Times, if the read-write head is attached to the top, before long, grinding head was gone. Such a close distance, if the earthquake do not, as long as there are so head trembling a little, ranging from hard disk damage, while in read-write head crash(HDD term). So hardware earthquake is very important.

Fault-tolerant error correction Design: hard disk fault-tolerant error correction capability is hard since there both in IT Hard ware industry or the software industry has sought to solve a problem. For an embedded system, you want to be perfect design fault-tolerant error correction, very difficult. But for embedded system design intent in terms of: embedded systems has always been the pursuit of better stability and speed of execution and design, but there is a problem can not be ignored is that portability is poor, resulting in a design once it is impossible to have too big changes. So it's the first design ideas is very important. Fault-tolerant embedded systems for hard disk error correction, the current effective way is to read and write control.

Future: Let the store smarter

Only continuous innovation in order to make car DVR Market faster. It is understood that the manufacturers have already begun to consider the on-board DVR Some intelligent processing functions, such as increased recognition, people counting, feature recognition and other functions, to increase the usefulness of automotive systems and targeted, so that storage more intelligent.

When violations occur after the car, the police only through careful observation of the crime who look, dress, etc., as the case when the person appears again to be arrested according to the judgment, such an approach is a waste of time, it is not flexible enough. Moreover, the center managers at each viewing video playback or real-time video streaming, it will inevitably be missed case of certain events. So, for car DVR Implants"Nervous system"Let it replace the human brain to analyze, judge, will be the future direction of development.

The advantage of adding intelligent analysis technology, intelligent analysis techniques using computer powerful data processing capabilities, the video screen for high-speed analysis of massive data, information filtering out the user does not care, just to provide useful information for monitoring critical person, so that it can effectively saves bandwidth, greatly enhancing the available network bandwidth.

More importantly, is Video Technology can be analyzed in real-time or recorded video streams, thereby detect suspicious activity, event or behavior patterns, you can make video surveillance in the search for suspects after converting an adjunct to prevent the incident was a crime occurred.

Intelligent car in the future DVR Storage applications will play an increasingly important role, the manufacturers who will continue according to the user's needs, develop more innovative technologies to protect the integrity and availability of recorded data.
