Description

Method of driving safely on water ice and tools for safe navigation

technical field

The invention relates to a method for driving safely on an ice layer on the water surface and a tool for performing safe navigation thereof.

Background technique

For a long time, when the driver drove over the river bed ice or the sea ice, because the specific conditions of the ice thickness in different regions were not clear, people and cars often fell into the ice cave (due to reasons such as eddy currents) The phenomenon that the ice layer is too thin due to the formation of a hole in the lower part of the ice layer) or the event where the ice layer is thinner (caused by the local water flow in the lower part of the ice layer).

People already know that many scientific methods can measure the thickness of ice, for example, the technology of ice thickness measurement using ultrasonic and optical technologies, especially the method of using ultrasonic wave to measure ice thickness involves relatively simple equipment and relatively small volume. Small.

The current wireless communication technology is quite developed, and any measurement data information and control information can be directly sent to a short-distance destination through radio transmission.

Contents of the invention

Purpose of the present invention:

It is to propose a method for driving safely on the ice layer on the water surface and the structural form of a safe navigation tool utilized in order to realize the method.

Key of the present invention is:

A method of using a safety navigation tool cart equipped with water surface ice thickness measuring instruments to guide vehicle drivers to drive safely on icy roads suitable for loading water and a structural form of the tool cart for implementing the safety navigation method are proposed.

Features of the present invention:

Because the present invention can help the driver of the vehicle grasp the general situation of the ice surface ahead in time, namely obtain the general situation of the thickness of the ice layer (the load-bearing requirement of the vehicle) and its width (the width requirement of the vehicle), this is to help the driver to avoid it in time. Ice caves (caused by underwater eddies) or areas with thinner ice layers (caused by high-speed underwater currents in local areas) create conditions for improving the safety of driving on ice (very close to foolproof) .

Description of drawings

Fig. 1 illustrates the general situation of the navigation of the present invention on the ice layer; Fig. 2 illustrates the specific driving route of the present invention when navigating (illustrated with a top view).

1: Ice surface thickness measuring probe very close to the ice surface; 2: Safety navigation light tool vehicle; 3. Small wheels; 4. The general direction of travel of the safety navigation light tool vehicle for controlled road exploration: 5. In the general direction of travel The "Z"-shaped driving trajectory set under the framework; a: ice layer; b: water body; c: river bed or bottom surface of the coast; P: vehicle.

Detailed ways

As shown in Figure 1, when a certain driver drives a vehicle P and needs assistance to cross the ice layer a on the water surface of a river bed, that is, in order to realize the purpose of the above invention, the following technologies can be used:

The driver of the above-mentioned vehicle P driving on the ice layer a on the water surface uses the remote control to determine that the light tool vehicle 2 performing safety navigation is in front of the road explorer. The tool cart 2 realizes the above-mentioned general direction of travel 4 in the form of a "Z"-shaped traveling track 5, and continuously measures the thickness of the ice layer a during the entire driving process of the light tool cart 2 and deduces the thickness of the ice layer a. The width of layer a, and, at any time, notify the above-mentioned obtained data related to the thickness and width of ice layer a to the driver of the vehicle P driving forward following the general direction of travel; - the above-mentioned "remote control" and " The best form of "notification" is wireless transmission.

The described traveling track 5 in the shape of a "Z" under the framework of the general direction 4 of road exploration in front is determined by the length of the straight-line travel distance of the above-mentioned light tool vehicle 2 and the next corresponding turning angle. The above-mentioned two methods are pre-programmed, or the above-mentioned two methods are determined by the driver of the vehicle P according to visual inspection. ——The "Z"-shaped running track 5 relates to the general direction of travel 4 that the guiding vehicle P will follow, and the minimum width under the frame of the general direction 4 of travel, that is:

Said width within the framework of the general direction of travel 4 should be at least equal to the frontal width of the vehicle P to be navigated.

During the entire driving process of the vehicle P:

A. If the driver of the vehicle P knows that the ice layer a ahead is suitable for the vehicle P to pass through, the vehicle P is allowed to continue driving in the general direction 4 of the light tool vehicle 2;

B. If the driver of the vehicle P knows that the ice layer a ahead is not suitable for the vehicle P to pass through (it must be that at least one of the measured ice layer a thickness and the derived width does not meet the requirements), Just remote control this light tool vehicle 2 in time to change its original general direction of progress 4, namely turn and divert to detect and travel, and the vehicle P that is navigated also turns and diverts to travel thereupon.

The structural form of the safety navigation tool cart:

C. An ice surface thickness measuring probe 1 controlled by an ultrasonic thickness gauge or an optical thickness gauge is installed on the front bottom of the light tool cart 2 for safe navigation. ——In the present invention, the equipment used to control the ice layer a thickness measuring probe 1 belongs to the ultrasonic ice layer a thickness gauge or the optical ice layer a thickness gauge of the prior art, and the requirements for its test accuracy generally do not need to be very high; The shape design of the light tool cart 2 can be controlled at about half a cubic meter, or less.

D. The light tool vehicle 2 that performs safe navigation is installed with a wireless transmission system (transmitting the thickness and width data or/and images of the ice layer a to the vehicle P) and a wireless receiving system (receiving) for wireless transmission and wireless remote control. Vehicle P’s remote control command to itself). - The wireless transceiver system installed on the light tool vehicle 2 should be permanent, while the wireless transceiver system installed in front of the driver in the vehicle P should be temporarily configured, when the vehicle P completes crossing a certain river Or after the near sea surface ice layer a, it can be taken off and handed over, allowing the drivers of other vehicles P who need it later to use.
