Three requirements for the "high speed dome" in the highway monitoring system

At present, the expressway monitoring system is one of the more important three items in the mechanical and electrical engineering of expressway traffic engineering, and it is playing an increasingly important role in the management of expressways. With the continuous improvement of highway management requirements, toll management, data communication, and image monitoring have become an indispensable part of modern highway construction. Highway monitoring also has stricter requirements on the system, mainly reflected in the following aspects:

1. The stability of the whole system is required

The low failure rate of the equipment and the long-term good operation index are getting more and more attention.

2. High image quality

The system requires that the image can be clearly distinguished and can be used in various environmental and climatic conditions. In addition, the visibility of the monitoring image of the monitoring object such as the vehicle number and the like at night must be improved. These aspects have also become the focus of attention. One of the important indicators.

3. The system is required to have good maintainability

Adopt relatively few system equipment and modular design of system equipment to facilitate system replacement and maintenance and long-term maintenance investment during use. The system requires scalable performance and more compatible equipment in future system upgrade Complete the system upgrade at the least reasonable cost.

Editor's note: The front-end cameras of highways are generally fixed-point cameras, uniform-speed dome cameras and high-speed dome cameras, which have different applications according to the needs of monitoring points. Usually toll booths and toll lanes need to be monitored in real time, so toll booths generally use small hemispheric cameras, which is not only conducive to monitoring, but also does not affect the appearance of the environment. However, due to the fixed monitoring range and limited monitoring range of toll lanes, outdoor gun-type fixed cameras should be used.
