Description
Technical Field
The invention relates to the technical field of monitoring of dangerous chemical vehicles in tunnels; in particular to a method for a highway long tunnel dangerous chemical vehicle detection system.
Background
With the stable development of the chemical industry in China, the demand of dangerous chemicals in various industries is gradually increased, and the dangerous chemicals become the support for the economic development in China. Because the dangerous chemicals have certain toxicity, the special properties of the dangerous chemicals can cause explosion, combustion supporting and other conditions after accidents are caused, if the dangerous chemicals are not paid attention to in the actual transportation process, the dangerous chemicals can easily cause casualties, and the surrounding environment can be polluted by chemical substances. At present, most of dangerous chemicals in China are transported through highways, and the transportation process is often accompanied by great risks, so that once accidents occur in high-speed transportation, different degrees of injury can be caused to people and the environment. Therefore, the prevention and research work is carried out on the dangerous chemical transportation system in the long expressway tunnel, and the management and control work in the long expressway tunnel is enhanced, so that the transportation safety of dangerous chemical vehicles in the long expressway tunnel is ensured.
Because the space in the long tunnel and the influence of environmental factors can not receive signals of external personnel when a fire disaster occurs, and meanwhile, whether a large amount of spilled dangerous chemical liquid is remained in the tunnel can not be accurately judged, the fire extinguishing scheme and the rescue unfolding mode are determined, and therefore, the control of dangerous chemical vehicles in the long tunnel on the expressway is particularly important. The management unit in the tunnel has the right of managing the electromechanical equipment of the tunnel, and can check the video monitoring in the tunnel first. At present, most expressway long tunnels in China are internally provided with a fire alarm system, a video detection system and a vehicle detection system, but the detection systems in the tunnels cannot detect the running state of dangerous chemical vehicles in the long tunnels, and data such as the running state of the dangerous chemical vehicles in the tunnels and information of articles transported in the vehicles cannot be automatically acquired immediately when fire occurs in the long tunnels, so that the form monitoring capability of the dangerous chemical transport vehicles in the operation management of the long tunnels is insufficient.
At present, the satellite positioning device which accords with the technical requirement of a vehicle-mounted terminal of a satellite positioning system of a road transport vehicle is installed on a dangerous chemical vehicle before the vehicle leaves a factory in China, and the dangerous chemical vehicle is dynamically monitored in real time. Each dangerous chemical enterprise mainly carries out real-time dynamic monitoring of dangerous chemical vehicles by the enterprise, and through intelligent video monitoring equipment, unsafe driving behaviors such as fatigue driving of a driving driver, call receiving and overspeed driving in the driving process are mainly carried out in real-time early warning reminding, and the driving can be adjusted through voice broadcasting of an intelligent system loaded in the vehicle in the driving process, so that potential safety hazards in the driving process are timely eliminated. However, because the intelligent video monitoring equipment is transmitted by means of signals, when the dangerous chemical transport vehicle enters the long expressway tunnel, due to the influence of the environment in the long tunnel and signal factors in the tunnel, the condition that the intelligent video monitoring equipment does not have information often happens in the long tunnel, so that the intelligent video monitoring equipment is disconnected, and the running condition of the dangerous chemical transport vehicle in the long expressway tunnel can not be mastered in real time.
Traffic accidents of dangerous goods transportation vehicles usually occur under the condition of no sign, and once the accidents occur in a long expressway tunnel, serious consequences are faced, particularly in the tunnel with large traffic flow, a series of destructive effects such as combustion, explosion and the like caused by dangerous goods accidents can bring about great harm to the environment of normal vehicle traffic and surrounding areas in the long expressway tunnel, and if the accidents occur in the tunnel, measures are not taken in time for treatment, and even larger-scale casualties can be caused.
Besides the dangerous and destructive aspects, the dangerous chemical transport vehicle has different traffic safety accidents in expressway long tunnels and traffic accidents of other common vehicles, and has higher requirements on rescue schemes and accident handling levels adopted after accidents. Most traffic accidents of common road dangerous chemicals transportation vehicles can be handled by road traffic departments, and if serious traffic accidents occur, fire protection, medical treatment, public security and the like are needed to be matched. These departments have very specialized equipment and skill levels, and are trained to handle sudden emergency events in a most straightforward and efficient manner. If the dangerous chemical accidents in the long tunnel are very serious, the serious traffic disasters are caused, and the serious traffic disasters are required to be reasonably commanded by a major accident combined command center, so that each rescue department is guided to rescue in a standard way.
