The method comprises the following steps of carrying out learning training on a prediction model by utilizing a large amount of weather forecast data and actual rainfall depth data of each road section, so that the prediction model has certain perception capability; the prediction model can utilize the currently broadcasted weather forecast information to carry out data analysis, predict the information such as precipitation, water level and the like of each road section according to the past experience value, further judge the driving danger degree of each road section in a period of time in the future according to the information, provide early warning information for a driver, facilitate the driver to select a safer route to go out in advance, and further improve the driving safety.
The water depth analysis module is used for receiving the water depth monitoring data and the elevation data marked on each road section, calculating to obtain a height difference value between the elevation data of the current road section and the elevation data of the front road section, and adding the height difference value and the water depth monitoring data to obtain a water depth value of the front road section;

The system can mark the altitude information on the electronic map, can acquire the altitude data of each road section in the automobile driving road when the automobile goes out in rainy days, and comprehensively analyzes the water depth data acquired in real time and the altitude data to determine the emergency strategy to be executed by the system.
The first water depth threshold is set to avoid engine flooding and vehicle shut-down. Since the exhaust port is lower than the intake port, it is safe to refer to the position of the exhaust funnel as the first water depth threshold. Once the water depth exceeds the height of the stack, the probability of vehicle stall increases. The height between the air outlet of the common car and the ground is 20-30 cm, and the height between the air outlet of the common car and the ground of the SUV is 30-40 cm, so that the vehicle can run safely as long as accumulated water is not more than one half of the height of a tire.
The second water level threshold is set to avoid that the chassis of the automobile is soaked by accumulated water, and further, each electronic element and the pipeline are corroded. The height of the air inlet is the limit wading index of the vehicle, when accumulated water reaches the height of the air inlet, if the vehicle is still running, the accumulated water can cause the vehicle to be directly flamed out and short circuits occur in electronic elements, so that permanent damage is caused. For this reason, the second water level threshold is set at a height below the air inlet to solve the above-described problem.

As shown in fig. 3, the water depth monitor 1 in this embodiment may use an ultrasonic liquid level sensor to monitor and generate water depth monitoring data, wherein the ultrasonic liquid level sensor is symmetrically distributed above each tire. The four ultrasonic liquid level sensors are used for measuring for multiple times from the periphery of the vehicle body within a certain time period, so that misjudgment caused by factors such as road splash splashing or raindrop contact is avoided, and detection precision is improved.

In order to realize the lifting function of the mechanism, as shown in fig. 5, the lifting mechanism specifically includes: servo motor 4, transmission 5, pneumatic cylinder 6, telescopic link 7 and base 8, servo motor 4 be fixed in on the vehicle floor 9, this servo motor 4's signal input part is connected with drive module to controlled by drive module, transmission 5 connect between servo motor 4 and pneumatic cylinder 6 for transmit the power of 4 outputs of servo motor to pneumatic cylinder 6, telescopic link 7 set up between pneumatic cylinder 6 and base 8, this telescopic link 7 is driven by pneumatic cylinder 6 and is made it extend to the road surface direction, and then makes base 8 whereabouts and support on the road surface.
When the water depth monitor senses that the vehicle is in a deep water level environment, the driving module controls the servo motor 4 to operate through the sent trigger signal, the telescopic rod 7 is extended, and the vehicle body can be raised by a corresponding height according to the liquid level height measured by the water depth monitor, so that the vehicle body is prevented from being soaked by water. When the monitoring water level is reduced to the safe height, the lifting mechanism is controlled by the driving module to execute the contraction action of the telescopic rod 7, and after the telescopic rod 7 is reset, the vehicle body naturally descends to the road surface.
EXAMPLE III

Because of the existence of certain time delay in water depth detection and data processing, the automobile still keeps the current speed for a certain distance before the system makes emergency action; at the moment, if the automobile is just in a downhill road section and the slope is large (such as in a lower bridge road section), a large water level difference is generated before and after the section of the road, so that the automobile body can be rapidly overflowed by accumulated water, and the automobile door can not be normally opened due to the hydraulic action or power failure self-locking, so that life danger is inevitably brought to personnel in the automobile, and the situation that the automobile is difficult to break window glass manually is avoided. In order to solve the problem, the system is additionally provided with a window glass breaking mechanism, when special dangerous situations such as the out-of-control lifting mechanism and the rapid submergence of a vehicle in water occur, the driving module is used for driving the window glass breaking mechanism to be started to break the window glass so as to facilitate escape of people in the vehicle under the conditions that people exist in the vehicle and the water level is higher than a set third water depth threshold value. In addition, in order to realize the emergency treatment function, the third water depth threshold may be set to a height of the window glass.

Based on the vehicle window breaking mechanism with the structure, as shown in fig. 6, a guide wall 20 may be further disposed in the housing 12, and the breaking hammer 14 is sleeved in a channel formed between the two guide walls 20, so that the breaking hammer 14 can move along the channel, and the breaking hammer 14 is prevented from deviating from a window when moving outwards.
In addition, the top surface of the hammer head 15 of the breaking hammer 14 can be provided with a conical bulge 21, and under the condition that the thrust force applied to the breaking hammer 14 is not changed, the contact area between the conical bulge 21 and the glass is small, so that the pressure intensity is increased, and the breaking efficiency of the mechanism is improved.
The system with the structure is used for monitoring the automobile in real time, and the concrete process is as follows:
in the driving process of the automobile in rainy days, the water depth monitor senses the road surface water depth of the area where the automobile is located in real time, and the water depth monitoring data and the altitude data of the front road section are subjected to comprehensive analysis continuously through the central controller. After data analysis, the following different processing strategies can be obtained:
when the accumulated water in the front road section is judged to be deep (namely the accumulated water exceeds a first water depth threshold value set by a system), the central controller triggers the early warning mechanism to send an early warning signal to a driver so as to remind the driver to select other safer roads to drive in advance;
when a driver does not take corresponding risk avoidance measures according to the early warning signal and continues to drive on the road section or is in a flameout and parking state, and at the moment, if the depth of the accumulated water at the position of the automobile is judged to exceed the first water depth threshold value, the central controller triggers a brake system and an engine control system which are arranged in the automobile to respectively execute braking and engine closing operations so as to avoid engine water inflow;
when the water level continuously rises to exceed the second water depth threshold value, the central controller triggers the lifting mechanism to execute the vehicle body lifting action so as to prevent all electronic elements arranged in the vehicle from being soaked by water;
