Description

Technical Field

[0001] The invention relates to the technical field of simulated ice surface, and in particular to a water system of a simulated ice surface system. Background Art

[0002] Rainy and snowy weather often makes the road slippery, greatly increasing the difficulty of driving. In this case, the vehicle is prone to losing control due to wheel slippage or insufficient grip, which increases the risk of accidents. Especially in situations such as sharp turns, braking or acceleration, the stability of the vehicle will be significantly reduced, which may cause serious traffic accidents. To deal with such problems, we have developed a simulated ice surface system that can accurately simulate the dynamic performance of the vehicle under different degrees of wetness to test its driving performance.

[0003] Through this system, engineers and researchers can deeply analyze the performance characteristics of vehicles under complex weather conditions, thereby providing data support for optimizing vehicle safety design. In addition, the simulated ice surface system can also be used for driver safety training. In a controlled environment, drivers can learn how to keep the vehicle stable on slippery roads and improve their ability to handle emergencies, thereby significantly reducing the probability of accidents.

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to simulate the core road friction characteristics, the water system is one of the core components of the entire simulated ice surface system, which can be used to control the slippery range and degree of the road surface. Therefore, in order to further improve the authenticity of the simulation conditions and the accuracy of the experimental data, it is necessary to provide a safe and controllable water system to more realistically simulate the vehicle performance on slippery roads.

[0036] To this end, the present invention provides a water system for simulating an ice surface system. Figure 1 Schematic diagram of the water system of the simulated ice surface system provided by the present invention. Figure 1 As shown, the system includes:

[0037] A water system groove 110 and a water system functional area 120;

[0038] Among them, Figure 2The water system groove 110 shown is deployed at a preset position of a preset road surface, and a plurality of water film nozzles and water barrier nozzles are installed in the water system groove 110. The water film nozzle is used to arrange water films at corresponding positions in the driving direction of the target vehicle according to the water film arrangement instruction. The water films may include water films on both sides and water films behind the pumping plate (the pumping plate is used to provide lateral traction for the target vehicle based on its own lateral acceleration movement to simulate the rear wheel slippage of the vehicle, and the vehicle travels from the pumping plate to the preset road surface) to simulate slippery road conditions; the water barrier nozzle is used to arrange water barriers with a certain height and width at corresponding positions of the preset road surface according to the water barrier arrangement instruction to simulate obstacles on the road for the target vehicle to avoid.

[0039] In some embodiments, a plurality of water film nozzles in the water system groove are deployed at one end of the pumping plate on both sides of the preset road surface, and are used to arrange water film in a preset water film area at one end of the preset road surface close to the pumping plate, so that the target vehicle can enter the slippery road surface after passing the pumping plate; the pumping plate is used to provide lateral traction for the target vehicle based on its own lateral acceleration movement.

[0040] However, when there is wind and the wind direction and wind speed may change at any time, the water column sprayed by the water film nozzle will be offset, which may cause some areas in the preset water film area to be not covered by the water film. In order to solve this problem, in addition to the existing water film nozzles, an additional water replenishment system can be arranged in the water system groove 110. The water replenishment system can be deployed at one end of the preset road surface close to the pumping plate and located between the above-mentioned several water film nozzles to replenish water when the water column sprayed by the water film nozzle cannot arrange a complete water film in the preset water film area due to the influence of wind, so that the water film can cover the entire preset water film area. In some embodiments, when the real-time wind speed is greater than the preset wind speed parameter, the water replenishment system is turned on.

[0041] The preset wind speed parameter can be determined based on the following steps:

[0042] Step 1: Based on multiple wind direction and wind speed parameter groups, as well as the angles and unit water outputs of the multiple water film nozzles, determine the water film range of the multiple water film nozzles under the wind conditions corresponding to each wind direction and wind speed parameter group.

[0043] Here, any wind direction and wind speed parameter group includes a sample wind direction parameter and a sample wind speed parameter. The wind conditions corresponding to different wind direction and wind speed parameter groups can be simulated through the simulation environment, and the water film nozzle can be controlled to spray water at a preset angle and a preset unit water output under the corresponding wind conditions, thereby determining the water film range of the above-mentioned several water film nozzles under the wind conditions corresponding to each wind direction and wind speed parameter group.

[0044] Step 2: Based on the wind direction and wind speed parameter group whose water film range is greater than or equal to the preset water film area, determine the maximum wind speed parameter corresponding to each sample wind direction parameter.

[0045] Specifically, for any wind direction parameter, all wind direction and wind speed parameter groups containing the wind direction parameter can be obtained, and the water film range of the above-mentioned several water film nozzles arranged under the wind conditions corresponding to all wind direction and wind speed parameter groups containing the wind direction parameter can be determined. Subsequently, the water film range that is larger than the preset water film area is screened out from the above-mentioned water film range, and the wind direction and wind speed parameter group corresponding to the water film range that is larger than the preset water film area is determined. The minimum sample wind speed parameter is determined from the above-screened wind direction and wind speed parameter groups as the maximum wind speed parameter corresponding to the sample wind direction parameter. It can be seen that the maximum wind speed parameter corresponding to any sample wind direction parameter is the maximum wind speed that can ensure that the water film formed by the water film nozzle completely covers the preset water film area under the wind direction conditions corresponding to the sample wind direction parameter. Once the actual wind speed is greater than the maximum wind speed parameter, the water film formed by the water film nozzle cannot completely cover the preset water film area.

[0046] Step 3: Based on the maximum wind speed parameter corresponding to each sample wind direction parameter, determine the maximum wind speed parameter corresponding to the real-time wind direction as the preset wind speed parameter.

[0047] Here, the real-time wind direction can be determined, and the sample wind direction parameters corresponding to the real-time wind direction can be determined, so that the maximum wind speed parameter corresponding to the real-time wind direction can be determined based on the maximum wind speed parameters corresponding to each sample wind direction parameter, and the maximum wind speed parameter corresponding to the real-time wind direction can be used as the above-mentioned preset wind speed parameter.

[0048] In other embodiments, the installation position of the water replenishment system will also affect the final water film coverage. In order to ensure that the final water film coverage can completely cover the preset water film area, the minimum water film range and the wind direction and wind speed parameter group corresponding to the minimum water film range can be determined based on the water film range of the above-mentioned multiple water film nozzle arrangements under the wind conditions corresponding to each wind direction and wind speed parameter group. Subsequently, the water replenishment system is arranged outside the minimum water film range so that the water film area formed by the water replenishment system under the wind conditions of the wind direction and wind speed parameter group corresponding to the minimum water film range intersects with the minimum water film range.

[0049] In addition, in order to reduce the water output to avoid excessive water flowing into the bottom of the pumping plate, the unit water output of the water replenishment system can also be controlled according to the real-time wind speed (for example, controlling the working pressure). If the real-time wind speed is high, the unit water output is set to be larger, and if the real-time wind speed is low, the unit water output is set to be smaller.

[0050] In other embodiments, the water replenishment system includes a duckbill nozzle and / or a flat-head nozzle. The range of the duckbill nozzle is shorter than that of the flat-head nozzle, so the duckbill nozzle can be used to replenish the nearby water film, and the flat-head nozzle can be used to replenish the distant water film. When the replenishment system includes both the duckbill nozzle and the flat-head nozzle, if the real-time wind speed is greater than the preset wind speed parameter and the difference between the real-time wind speed and the preset wind speed parameter is greater than the preset difference, the flat-head nozzle is turned on; if the real-time wind speed is greater than the preset wind speed parameter and the difference between the real-time wind speed and the preset wind speed parameter is less than the preset difference, the duckbill nozzle is turned on.

[0051] In some embodiments, there are two water replenishment systems.

[0052] In some embodiments, the spacing between the duckbill nozzle and the flat-head nozzle is less than or equal to 30 cm.

[0053] like Figure 3 As shown, the water system functional area 120 may include a valve well 310, a sedimentation tank 320 and a water reservoir 330. The valve well 310 is used to inject water into the water system groove 110 and the water reservoir 330, the water reservoir 330 is used to supply water to the water film nozzle of the water system groove 110, and the water system groove 110 will supply water to the water barrier nozzle, and the sedimentation tank 320 is used to collect the water flowing back from the water system groove 110 and make the water flowing back from the water system groove 110 flow into the water reservoir 330. Figure 4 As shown, the sedimentation tank 320 is connected to the water system groove 110 through a return pipe, and the water storage tank 330 is connected to the water film nozzle of the water system groove 110 through a clean water pipe.

[0054] In some embodiments, Figure 3 As shown, the water system functional area 120 also includes a filtering device 340. Figure 4 As shown, the filter device 340 is connected to the sedimentation tank 320 through a return pipe and to the water reservoir 330 through a clean water pipe, and is used to filter the water flowing from the sedimentation tank 320 to the filter device 340 and discharge the filtered water into the water reservoir 330.

[0055] In other embodiments, Figure 3 As shown, the water system functional area 120 also includes a drainage well 350. The water system trench 110, the sedimentation tank 320 and the reservoir 330 are all provided with overflow ports, such as Figure 4As shown, the water system groove 110, the sedimentation tank 320 and the water storage tank 330 are connected to the drainage well 350 through corresponding overflow ports, overflow pipes and drainage pipes. On the one hand, the setting of the overflow port, overflow pipe and drainage well can prevent the abnormal water level of the water tank with water storage function from causing water overflow, so the water flowing out of the overflow port uniformly flows from the overflow pipe to the drainage well by gravity; on the other hand, all the water tanks with water storage function in the water system functional area 120 are equipped with drainage pipes, which can empty the water in the system during the equipment sealing stage in winter, and can have the function of cleaning and drainage when the water tank is dirty.

[0056] In some embodiments, the water system works as follows:

[0057] The water supply pipe in the valve well 310 injects water into the water system groove 110 and the water reservoir 330 in the water system functional area 120. When the water level line is reached, the water injection stops; the clean water in the water reservoir 330 is specially supplied to the water film nozzle by a water pump;

[0058] The water film nozzle and the water barrier nozzle in the water system groove 110 are activated, and the returned water is collected in the water system groove 110 and flows to the sedimentation tank 320 by gravity;

[0059] The sewage in the sedimentation tank 320 flows into the filter device 340 (the filter specifications of the filter device 340 are customized according to actual conditions) through the filter pump, and the filtered water flows into the water reservoir 330. Among them, the filter device 340 sucks water into the filter tank through the filter pump for circulation filtration, and uses physical media such as volcanic rocks, rattan cotton and brushes to remove suspended matter and impurities in the water to keep the water clean. Since physical filtration cannot completely remove all pollutants, the water quality and filter media can also be tested regularly, and the water body or filter media can be replaced as needed according to the test results to ensure the long-term stable operation of the system.

[0060] In some embodiments, the valve well 310, sedimentation tank 320, reservoir 330, filtration equipment 340 and drainage well 350 in the water system functional area 120 are all equipped with wire pipes in the same position, and the pipelines are unified and neat, which reduces the pre-buried pipelines of the demander and saves costs. The water system functional area 120 is also equipped with a liquid level switch for automatic water replenishment and water replenishment stop and a water replenishment solenoid valve to ensure the stability of the system water volume, and has the function of low temperature prompt manual drainage, zero degree automatic prohibition of water spraying function and automatic pump stop function below the safe water level. A separate forced drainage well can also be set around the installation position of the pumping system. The forced drainage well automatically identifies the depth of water accumulation on rainy days and actively discharges the water accumulated in the pumping system to prevent rainwater from entering the pumping system and damaging the equipment.

[0061] In summary, the water system provided by the embodiment of the present invention is provided with a water system groove and a water system functional area, wherein the water system groove is deployed at a preset position of a preset road surface, and a plurality of water film nozzles and water obstacle nozzles are installed in the water system groove; the water film nozzle is used to arrange a water film at a corresponding position in the driving direction of the target vehicle according to the water film arrangement instruction, and the water obstacle nozzle is used to arrange a water obstacle at a corresponding position of the preset road surface according to the water obstacle arrangement instruction; the water system functional area includes a valve well, a sedimentation tank and a water reservoir; the valve well is used to inject water into the water system groove and the water reservoir, the water reservoir is used to supply water to the water film nozzle, and the water system groove is used to supply water to the water obstacle nozzle; the sedimentation tank is connected to the water system groove by a return pipe, and the sedimentation tank is used to collect the water flowing back in the water system groove and make the water flowing back in the water system groove flow into the water reservoir; the water reservoir is connected to the water film nozzle in the water system groove by a clean water pipe, so as to safely and controllably realize the control of the slippery range and slippery degree of the road surface.
