Description
Technical Field
The invention relates to the field of intelligent highways, in particular to a highway safe driving system.
Background
The safety operation of the expressway is related to the life of the countryside, and with the increasing of the quantity of the reserved automobiles, the emission of pollutants such as smoke suspended matters, automobile tail gas and the like is continuously increased, so that the atmospheric pollution of the expressway and the surrounding area is increased, and the traffic operation environment is increased.
According to statistics of authorities, in recent years, about 43257 traffic accidents, 6269 deaths and 18867 injuries occur on the expressway every year, and according to analysis of traffic accident factors, severe weather causes about 50% of the total number of accidents, wherein the proportion of traffic accidents caused by fog and haze weather is as high as 30.8%. In addition, the fog and haze weather also causes the phenomena of expressway closure, traffic capacity reduction, vehicle congestion and the like, and seriously threatens the safe operation of traffic and the normal life of people.
Mist is the product of the condensation or desublimation of water vapor in near-surface air and is an aerosol system consisting of a large number of tiny water droplets or ice crystals suspended in near-surface air. Haze is a cloudiness phenomenon formed by suspending a large amount of particles such as smoke and dust, and its core material is dust particles suspended in the air, which are called aerosol particles in the weather. Haze formation requires 3 basic conditions: firstly, air humidity, secondly, ambient temperature and thirdly, the content of microparticles. The fog and haze weather reduces the air visibility, so that the sight distance of a driver is shortened sharply, the observation capability and the judgment capability of the driver are reduced, correct judgment cannot be made, the running speed of the expressway vehicle is reduced, the expressway is closed when the speed is serious, the traffic capability is reduced, and the operation benefit and the service level of the expressway are reduced. The adhesion coefficient of the expressway is reduced in foggy days, so that the braking distance of the vehicle is increased, and the occurrence of continuous rear-end collision or oversized traffic accidents of the expressway is easy to cause huge casualties and economic losses.
The existing haze treatment measures are provided from the angle of driving control at home and abroad. The Utah state is equipped with a demisting vehicle on a highway for mobile demisting, and liquid carbon dioxide is used for condensing the mist into water drops so as to achieve the demisting purpose. However, water drops are deposited on the road surface to cause the road surface to wet and slide, and the water drops are frozen in winter and the antifreezing agent is sprayed on the road surface. The university of eastern China Zhang Yang designs an ultrasonic defogging device. The device has high cost, and the resonance condition is difficult to meet. The university of lan Gao Genshu proposes a new centrifugal mist eliminator which is not very adaptable on roads. The method reduces traffic accidents in foggy days, but can not fundamentally solve the problems of traffic safety in foggy days, reduced speed, reduced traffic capacity, reduced operation benefit, over-high investment and the like. In addition, methods for controlling the exhaust emission of vehicles, multi-tree planting and the like are required to have slow action for a long time.
The method can not fundamentally change the traffic safety problem of the expressway in the foggy and haze weather, and has the problems of high investment, low effect, wet and slippery road surface deposition caused by water drops, defrosting by spraying antifreezing agent in winter and the like. The construction of expressways in China is in a rapid development stage, and the influence range of haze weather on roads is further widened. Therefore, the advanced technology for ensuring the safe and efficient operation of the road under the condition of fog and haze is researched while the road is built, and is an urgent task for road scientific researchers.
Disclosure of Invention
The invention aims to provide a highway safe driving system, which solves the safety and operation problems caused by the influence of fog and haze weather on the line of sight of a highway in the prior art and achieves the aim of improving the driving safety of the highway in the fog and haze weather.
The invention is realized by the following technical scheme:
a highway safe driving system comprising:
an air suction unit for sucking road surface air;
the purifying unit is used for purifying the air inhaled by the air inhaling unit and exhausting pollutants;
an air curtain unit for forming a first air curtain above the road surface from the air purified by the purifying unit;
the illumination unit is used for projecting a group of illumination light rays and a group of yellow light rays, the illumination light rays are projected to the road surface, and the yellow light rays are projected to the first air curtain from bottom to top.
Aiming at the problems of traffic safety and operation limitation caused by the influence of fog and haze weather on the line of sight of the expressway in the prior art, the invention provides an expressway safe driving system, which is started in the fog and haze weather, and is used for sucking air above a road surface through an air suction unit, purifying the fog and haze in the sucked air through a purifying unit and discharging pollutants such as fog water, tiny particles and the like after the treatment. The air after purification unit treatment gets into the air curtain unit, forms first air curtain at least, and first air curtain is located the road surface top, through the setting of first air curtain, can prevent the subsidence of fog, haze gas, constructs a safe driving space for the highway surface, improves the highway and requires under fog, haze weather's visibility, improves road traffic capacity, reduces the traffic accident rate.
Furthermore, the lighting unit in the present application is configured to project a set of illumination light rays and a set of yellow light rays, wherein the illumination light rays are directed towards the road surface, and the yellow light rays are directed towards the first air curtain from bottom to top. The yellow light is projected to the first air curtain, and is refracted by the tiny water drops or haze particles of the fog to return to the road surface through the refraction of the haze-containing air on the first air curtain, so that the yellow light and the illumination light directly projected to the road surface together form mixed light illumination, and a safe driving space of the expressway is formed. The lighting unit of this application compares with traditional street lamp illumination mode: because the yellow light has the scattering effect, the light beam can be scattered forward as far as possible to form light clusters with larger area, so that a driver can see a target clearly, light pollution is reduced, glare interference to the driver caused by too strong illumination light beam is avoided, full scattering and uniform distribution of road light are ensured, the illumination requirement of expressway illumination even at night under special weather such as fog, haze and the like is met, road traffic capacity is improved, traffic accident rate is reduced, sight safety of the driver above the road is ensured, traffic running environment of the expressway is improved, and the aims of safe and efficient running of the expressway under fog, haze weather and night conditions are fulfilled.
It should be noted that, the principle that this application can normally be realized is that: because the sight space required by the driving on the expressway has limitation, the fog and haze in the air do not need to be completely eliminated, and the driver can safely and normally drive at a high speed as long as the driver on the expressway can have better visibility in the safe sight space.
Further, the air suction unit comprises an air inlet pipe, a fan and a plurality of air suction pipes, wherein the air inlet pipe is arranged along the length direction of the road surface, the fan is communicated with the air inlet pipe, the air suction pipes are distributed on the air inlet pipe, and the suction ends of the air suction pipes incline upwards towards the direction of the road surface. The air inlet pipe is arranged along the length direction of the road surface, can be arranged on two sides of the road surface to serve as guardrails, and can be arranged in the middle of the road to serve as a partition of a bidirectional lane, so that equipment such as traditional guardrails can be replaced, or the equipment can be additionally arranged, and the air inlet pipe has extremely strong functionality in normal weather.
Further, the purification unit comprises hollow upright posts communicated with two ends of the air inlet pipe and air purification equipment positioned in the hollow upright posts, and the bottoms of the hollow upright posts are communicated with underground sewage pipelines. This application connects the cavity stand at the both ends of air-supply line, makes the inside intercommunication of cavity stand and air-supply line inside, and in the hollow stand of inhaled air entering both sides through the air-supply line, the air purification equipment in the rethread cavity stand purifies, and the outside discharge of air admission air curtain unit after the purification, and the debris of being filtered out then gets into low blow off pipeline and walks away. The hollow upright post of this scheme can regard as the upright post of traditional guardrail to use, has the effect of the air current passageway of purification process, the blowdown passageway of discarded object concurrently.
Further, the air curtain unit comprises an air outlet pipe communicated with the hollow upright post, and a first air outlet with an upward inclination of the discharge end towards the road surface direction is arranged on the air outlet pipe. This scheme sets up a plurality of tuber pipes on the cavity stand, and the air after being purified passes through the tuber pipe, upwards discharges towards the slope of road surface top to stable formation first air curtain.
Further, the air outlet pipe is parallel to the air inlet pipe, the air outlet pipe is positioned above the air inlet pipe, and the first air outlet is higher than the air suction pipe. The air outlet pipe is parallel to the air inlet pipe, and the air outlet pipe and the air inlet pipe can form a double-layer structure together to be used as a more stable guardrail. The first air outlet is higher than the air suction barrel, so that the air suction barrel absorbs air from the lower part of the first air curtain, and then the air close to the road surface direction is guaranteed to be absorbed, and then the air in the safe sight range of a driver is guaranteed to be treated.
Further, the air curtain unit further comprises a second air outlet arranged on the air outlet pipe, and the discharge end of the second air outlet is inclined downwards towards the outer side of the pavement; the second air outlet is used for forming a second air curtain on the outer side of the pavement from the air purified by the purifying unit. The second air curtain can form outside air curtain in road both sides, reduces the haze and invades the space possibility above the road surface from the side, improves the protective capability to the visibility in the driver's the safe sight scope more.
Further, the purification unit further comprises a heat drying device located downstream of the air purification device. The heating and drying equipment is used for heating and interfering purified air, so that air forming an air curtain is heated, hot air flows upwards to prevent fog and haze from sinking, a safe driving space is further formed, the visibility requirement of expressway under fog and haze weather is met, road traffic capacity is further improved, and traffic accident rate is further reduced.
Further, the included angle between the air inlet pipe and the vertical direction is 125-135 degrees; the included angle between the first air outlet and the vertical direction is 125-135 degrees, and the ground clearance of the first air outlet is 4-5 meters; the included angle between the second air outlet and the vertical direction is 35-45 degrees, and the ground clearance of the second air outlet is 0.2-0.4 meter; the ground clearance of the air inlet pipe is positioned between the first air outlet and the second air outlet. Through strict calculation and experimental result display, the safe driving requirement can be met under the parameters of the scheme, the effect of demisting and haze is optimal, the visibility is best, and the energy is most saved.
Further, a partition plate is arranged in the air suction cylinder, and the partition plate divides the interior of the air suction cylinder into a first cavity with the air suction port and a second cavity with the air exhaust port; the inner wall of the air suction cylinder is provided with a first chute and a second chute, the axes of the first chute and the second chute are parallel to the connection line of the air suction opening and the air outlet, the partition board is in sliding fit with the first chute and the second chute, and the partition board gradually inclines downwards from the direction close to the first chute to the direction close to the second chute; the device also comprises an elastic piece arranged in the first chute, a slag discharging port arranged in the second chute and a plurality of air holes arranged on the partition plate; the slag discharging port is communicated to the outer side of the air suction cylinder; when no load is applied to the partition plate, the elastic piece enables the partition plate to slide to the top end of the stroke, and the slag discharging port is positioned below the partition plate.
In addition, because the suction cylinder is obliquely upwards arranged in the application, large-particle sundries in the atmosphere are easy to enter the rear end through the suction cylinder to cause damage, and particularly when sand and dust weather is encountered, the large-particle sundries are easy to enter in a large amount to cause blockage or damage due to the fact that sand and dust subside in a large amount in a short time. Based on this, this scheme improves the inner structure of inhaling dryer:
the air suction tube is connected with the air inlet tube through the air outlet and sucks air from the air suction tube. The baffle is arranged in the air suction cylinder, the air suction cylinder is divided into two parts through the baffle, one side of the air suction cylinder facing the air suction opening is a first cavity, and one side of the air suction cylinder facing the air exhaust opening is a second cavity. In the scheme, the partition plate is in sliding fit with the inner wall of the air suction cylinder, and the sliding direction is along the axial direction of the first sliding groove and the second sliding groove, namely along the connecting line direction of the air suction opening and the air exhaust opening. And the baffle is from being close to the direction of first spout to being close to the second spout gradually downward sloping, and here downward sloping is in vertical direction, and the baffle is close to the height of one end of second spout, is less than the baffle and is close to the height of one end of first spout for debris that falls on the baffle can be under the gravity effect automatic to the second spout direction slip. The elastic force of the elastic member acts on the partition plate to push the partition plate to move upward or have upward trend under normal conditions. When the scheme is specifically used, firstly, the elastic piece drives the baffle plate to slide to the top end of the stroke in the air suction cylinder, and at the moment, the upper surface of the baffle plate is not communicated with the slag discharge port; when sundries enter the air suction cylinder gradually to be accumulated on the partition plate, or when a large amount of sand and dust enter the air suction cylinder rapidly to be accumulated on the partition plate in sand and dust weather, after the load on the partition plate is large, the gravity of the partition plate overcomes the elasticity of the elastic piece to drive the partition plate to slide downwards gradually, and when the partition plate slides to be equal to the slag discharge port or is positioned below the slag discharge port, the weight on the partition plate slides to the direction of the second chute on the inclined partition plate, so that the heavy dust can be discharged outwards from the slag discharge port automatically; when certain sundries are discharged, the load on the partition plate is reduced, and the elastic piece drives the partition plate to ascend again, so that the process is repeated. In the scheme, air enters the second cavity from the air holes, and disturbance of the air can accelerate outward discharge of sundries to a certain extent. Of course, in this scheme, because the air holes are needed to let air pass through the partition board, some small-particle impurities such as PM2.5 and the like inevitably enter the second cavity, but this does not affect the treatment of the scheme on large-particle impurities such as sand dust, and the setting of this scheme is only for reducing the interference of impurities, and properly improving the capability of resisting severe weather such as sand dust, but not for completely eliminating the interference.
Further, a plurality of baffles which are distributed in a staggered manner are arranged in the first cavity, and each baffle comprises a fixed end fixed on the inner wall of the air suction barrel and a suspension end suspended in the air suction barrel; the hanging end is not contacted with the inner wall of the suction cylinder as the name implies, and a gap for air flow to pass through is necessarily arranged between the end of the hanging end and the inner wall of the suction cylinder. In this scheme a plurality of baffles are at first cavity internal staggered distribution, at first all baffles all are located the baffle top, and secondly the baffle of staggered distribution can provide the flow channel who is approximate "style of calligraphy for the inspiratory air current for carry the air current of grain debris in the area of carrying constantly beats on each baffle, is favorable to separating out grain debris from wrapping up in of air current and holding in, can reduce to a certain extent that it flows fast and extrudees to the bleeder vent in the risk that causes the jam along with the air current.
The fixed end is higher than the suspension end in horizontal height; the baffle gradually inclines towards the direction of the exhaust outlet from the fixed end to the suspension end; the particle sundries falling on each baffle plate can slide downwards under the action of gravity and finally fall onto the baffle plate.
For any two adjacent baffles, the suspension end projection of the baffle above is projected along the connecting line direction of the air suction port and the air exhaust port, and the suspension end projection falls on the surface of the baffle below; the particle sundries sliding from the upper baffle plate can fall onto the surface of the lower baffle plate, so that the particle sundries sequentially slide down, and the possibility that the particle sundries are wrapped by the air flow again due to overlarge falling distance is reduced.
