Application And Development Trend Analysis Of 3G Mobile DVR With Bus People Counter Kit

- Jul 20, 2017-

The so-called 3G Mobile DVR With Bus People Counter Kit, that is, the use of 1U Standard architecture, installed in the vehicle radio or CD player location, access to 1-4-channel images, to monitor the situation in vehicles and video, the current 3G Mobile DVR With Bus People Counter Kit compression algorithm is mainly MPEG4 and H. 264.

Can the onboard DVR open a new concept of storage monitoring?

is the common surveillance DVR used in the car? The answer is No. Although the same as the general DVR embedded system, but the 3G Mobile DVR With Bus People Counter Kit technology than ordinary DVR more complex, the need to solve the key is also different. Because the vehicle in the mobile process, will inevitably be shaken, dust, power supply, and so on, these are doomed to the application of the 3G Mobile DVR With Bus People Counter Kit environment than the ordinary DVR worse.

Poor vehicle environment, multi-technology integration "stability" of the victory:

It is understood that in order to ensure that vehicles in operation can still achieve smooth storage, manufacturers of 3G Mobile DVR With Bus People Counter Kit to strengthen the technology mainly include shockproof, voltage-stabilized current, heat dissipation, wireless transmission and so on. The perfect combination of these technologies is designed to further improve the stability of onboard DVR storage.

Shock:

Due to the different conditions of the road, the earthquake-proof technology has become the most basic requirements of the 3G Mobile DVR With Bus People Counter Kit, including the whole machine shock absorber, hard drive frame damping, hard disk damping and other links, to achieve the entire 3G Mobile DVR With Bus People Counter Kit damping treatment.

In these damping links, the hard drive damping is the most important. This is because the most vulnerable parts of the 3G Mobile DVR With Bus People Counter Kit is the hard disk, if the hard drive is damaged, it will not be able to store the situation in the car, so the vibration of the hard drive is particularly important.

For the current method of damping, most of the market uses spring, as the structure of the shockproof material, the rubber cushion can play a certain role in the vertical force direction, but in fact the vibration direction is irregular in the driving state (especially under the bad road conditions), and the long time use will inevitably cause the equipment to malfunction. The spring and rubber pads actually do not absorb the energy of the vibration, but will store this energy, when reached a certain degree, will cause a greater rebound. According to him, there is a rubber gasket inside the practice, mainly to use oil compression than the advantages of small air to achieve better damping effect.

In addition, some manufacturers also have for the 3G Mobile DVR With Bus People Counter Kit for the suspension of the hard drive or chassis suspension shock absorber design, is the hard disk or the entire chassis to achieve a "dangling" state to achieve shock absorption.

Regulated power supply:

In addition to shock absorption, another important technology in 3G Mobile DVR With Bus People Counter Kit is the stability of the power supply. As the vehicle in the course of driving, the vehicle will have brakes, climbing, ignition and other actions, this behavior will make the output voltage of the vehicle fluctuations in different amplitude, it is easy to cause the phenomenon of burning car equipment, so the 3G Mobile DVR With Bus People Counter Kit itself must have a wide voltage input ability to adapt to this voltage change.

Thermal Resistance:

It is understood that the vehicle in the course of operation, there will be a large variation in the characteristics of temperature difference, many buses are installed in the 3G Mobile DVR With Bus People Counter Kit under the driver's seat or driving seat at the top of the closed space, this on-board DVR used performance higher requirements.

However, the industry believes that because the state and local governments have specific requirements for GPS positioning system and related documents, many transport companies are mandatory equipped with GPS positioning system, so the 3G Mobile DVR With Bus People Counter Kit added GPS function, is more in line with the needs of the bus.
