Embodiment Construction

[0031] see figure 1 In this embodiment, the structure of the freeway group fog real-time monitor is set to include a laser emission / reception module, a detector and a signal acquisition module, a laser driver and a timing control module, wherein:

[0032] The laser transmitting / receiving module includes a laser, a transmitting optical lens, a receiving optical lens, a small aperture diaphragm and a narrow-band filter; the output beam of the laser is collimated by the transmitting optical lens, beam expanded and then emitted; the laser scattered by the atmosphere returns to the The wave signal is received and converged by the receiving optical lens, and then passes through the aperture diaphragm and narrow-band filter in turn to obtain the light detection signal.

[0033] The output beam of the laser is optically collimated and expanded through the emitting optical lens to improve the collimation of the laser and reduce the divergence angle. While making the energy distribution...

Abstract

A real-time system for monitoring and pre-warning mist on a highway, which is characterized in that the system consists of a real-time monitoring instrument for monitoring mist on the highway, a wireless data transmission module, a safety pre-warning information display module, and a GSM communication module, wherein the real-time monitoring instrument is used for obtaining and outputting the visibility data information of the monitored area and taking the visibility data information as the system pre-warning information, the wireless data transmission module transmits the data information between a wireless data emitting module and a wireless data receiving module; the safety pre-warning information display module can display the visibility pre-warning information and the visibility data information on a display screen; the GSM communication module can send the pre-warning information to a communication base station and a central control room by the GSM network when the current visibility is judged less than the alarm threshold; and the communication base station sends the pre-warning information to the pre-warning area in the way of short messages of mobile phone. The system has the advantages of stable and reliable data monitoring, fast data transmission, wide information distribution channels, reliable and stable pre-warning information and strong timeliness, is suitable for being arranged in the whole line of the high, can solve the real-time monitoring and safety pre-warning problem of the mist on the highway, thus reducing or avoiding the traffic accidents of the highway due to the mist.

Description

technical field [0001] The invention relates to an early warning system, in particular to a fog monitoring safety early warning system applied on expressways. Background technique [0002] With the sustained and rapid economic growth, expressway construction has achieved unprecedented development. While the expressway is inserting wings for the economic take-off, frequent traffic accidents also greatly threaten the safety of people's lives and property, and affect the harmonious development of the social economy. The impact of many car continuous rear-end collisions, mass casualties and serious traffic accidents is particularly prominent. Therefore, all-weather real-time monitoring of fog along the expressway and effective early warning are of great significance to eliminate traffic accidents caused by sudden short-term low-visibility weather such as random fog. [0003] my country's existing highway cloud monitoring equipment can only forecast large-scale regional heavy f...
