Abstract
The invention relates to an automatic prompting-warning method for harm variables of a traffic environment of a tunnel. The method is realized according to the following steps: (1) uniformly arranging a plurality of independent detection devices in the tunnel along the longitudinal length of the tunnel; (2) detecting the decrement of light, passing through the gas, by virtue of the detection devices according to a light transmission principle, and calculating the content of harmful gas and a measured value of a ventilating condition according to relevant standards after signals are processed by virtue of a data processing device; and (3) transmitting the measured value to a display device by virtue of the data processing device. The invention provides an automatic prompting-warning system for the harm variables of the traffic environment of the tunnel. According to the system, the contents of toxic gas and carbon monoxide gas and the ventilating condition in the tunnel can be detected and warned in real time.
Description
Technical field
The invention belongs to technical field of automation, be specifically related to a kind of tunnel traffic environmental hazard variable automatic alarm system.
Background technology
In tunnel, ventilate smooth, toxic and harmful bulk deposition, exceed standard, easily cause the injury to human body, even because of inflammable gas bulk deposition, there is the situation of spark running into vehicle pass-through, be prone to the harm traffic safeties such as tunnel implode, even jeopardize people's life safety, cause the seriousness problem of fortune loss simultaneously.China's tunnel traffic does not have to carry out detection and the panalarm of toxic gas, carbon monoxide, ventilation condition in tunnel at present, and cannot toxic gas content, carbon monoxide and ventilation condition real time data in tunnel be detected and be reported to the police, caused in a lot of tunnels and blasted, caused the pernicious traffic hazards such as a large amount of life is lost one's life, property loss, interruption of communication.
And particularly, for compare Chang tunnel, those paths, its ventilation condition is more severe, toxic gas or flammable explosive gas are easier to gather, and its danger is higher.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned the deficiencies in the prior art, a kind of tunnel traffic environmental hazard variable automatic alarm system is provided, and this system has realized real-time detection and the warning to toxic gas content, carbon monoxide gas body burden and ventilation condition in tunnel.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of tunnel traffic environmental hazard variable automatic-prompting alarm method, and system, is characterized in that realizing in accordance with the following steps:
(1) at Nei Yan tunnel, tunnel longitudinal length, some independently pick-up units are evenly set;
(2) pick-up unit, according to optical transmission principle, detects light by the damping capacity of gas, and signal, after data processing equipment is processed, according to relevant criterion, calculates the measured value of harmful gas content and ventilation condition;
(3) data processing equipment by this transmitting measured values in display device.
Data processing equipment will surpass established standards part transmitting measured values to tunnel ventilation device gauge tap startup ventilation unit simultaneously or be transferred to and in display device, control vehicle condition and vehicle flowrate in step (3).A tunnel traffic environmental hazard variable automatic alarm system, is characterized in that, comprises signal connects successively pick-up unit, data processing equipment and display device.
Further, this pick-up unit comprise be installed on tunnel top or sidewall support, be installed on laser pick-off/transmitter and reverberator on support, the installation site of described laser pick-off/transmitter and reverberator is corresponding.
Further, described tunnel traffic environmental hazard variable automatic alarm system comprises some independent detecting units that arrange.
Further, described each detecting unit is along the uniform setting of tunnel longitudinal length.
Further, described each detecting unit is according to distributing and arrange in Shu tunnel, close two ends, center.
Further, described tunnel traffic environmental hazard variable automatic alarm system also at least comprises an optical spectrum analysis instrument.
Tunnel traffic environmental hazard variable automatic alarm system of the present invention utilizes laser to pass through the principle that γ-ray emission particular characteristics is decayed, by being arranged at detecting unit and data processing equipment and the display device in tunnel, realized toxic gas content in tunnel, carbon monoxide gas body burden and ventilation condition long-range, detect in real time and report to the police, the data of gas property and concentration in the tunnel that utilization detects, adjust at any time ventilation in tunnel, strict vehicle condition and the vehicle flowrate controlled, can effectively avoid the generation of great pernicious traffic hazard, avoid and reduce the loss of the person and property.
Tunnel traffic environmental hazard variable automatic alarm system of the present invention arranges compensate function, at optical lens, in contaminated situation, can automatically carry out gain compensation, thereby guarantee longer maintenance period.
Tunnel traffic environmental hazard variable automatic alarm system of the present invention arranges some detecting units by diverse location place in tunnel, can detect in real time the content of the toxic gas of position in tunnel, abnormal for gas flow in the tunnel producing due to uncertain factor, cause local gas in tunnel to be gathered, also there is significant preventive effect.
Meanwhile, in long path tunnel, the feature that center gas is difficult to dredge, the present invention has adopted center section densely distributed, and the two ends sparse Distribution Principles that distributes has further improved the effect of the omnidistance monitoring in tunnel.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tunnel traffic environmental hazard of the present invention variable automatic alarm system.
Embodiment
A tunnel traffic environmental hazard variable automatic alarm system, is characterized in that, comprises signal connects successively pick-up unit 1, data processing equipment 2 and display device 3.Pick-up unit comprise be installed on tunnel top or sidewall support, be installed on reception/transmitter and reverberator on support, the installation site of reception/transmitter and reverberator is corresponding.
Toxic gas content and ventilation condition tester carry out work according to optical transmission principle, emitting/receiving is relative with reverberator to be installed, utilize after support fixed alignment, the high laser focusing light beam that transmitter optical parts send, wavelength is 1.064um, become one and detect light beam, 3 meters, mounting distance interval (round double light path, actual detection light path is 6 meters), because light is by the decay of gas, receiver receives the laser beam being reflected back, after processing by signal, according to relevant national standard, calculate the measured value of harmful gas content and ventilation condition (carbon dioxide),
Toxic gas content and ventilation condition tester inside carry compensate function, at optical lens, in contaminated situation, can automatically carry out gain compensation, thereby guarantee longer maintenance period.
After table 1 normalization, laser is by the test value of gas with various content
By transmission network (wired and wireless two kinds of modes) by the measured value of the harmful gas content detecting and ventilation condition (carbon dioxide), be transferred to daemon software, daemon software is according to national road related specifications, by harmful gas standard, allow vehicle pass-through condition to be presented at alarm display apparatus, to driver and conductor, remind, to reach the effect of avoiding pernicious traffic hazard to occur.
