Description

  The present invention relates to a system capable of confirming a snow removal condition on a road.

Snow is removed as appropriate by snowplows on arterial roads and the like in winter.
However, in the past, general drivers only recognized that snow would be removed as appropriate.
Therefore, when heavy snow was falling, I was worried about whether snow was really removed, and I wasn't worried about whether it was snowing and then it was falling again and stuck. In particular, drivers who needed to drive at night were not worried about whether it would not be able to operate as planned because it wasn't snow-cleared during the daytime, or whether it would be safe to wait until morning.

  That is, the invention according to claim 1 makes it possible to easily grasp information on where and when snow removal has been performed.

As the position information, GPS information can be used.
The execution information may be configured based on state detection that recognizes that snow is being removed one by one, and is based on event detection that detects the start of snow removal and the end of snow removal and determines during that time that snow is being removed. It may be configured. Further, instead of detecting the state, the driver of the snowplow can manually operate the ON / OFF button and use the information as execution information.
The predetermined time can be, for example, every 1 minute, every 5 minutes, or every 10 minutes. The more detailed, the higher the real-time property.
Since the snowplows are distinguished by the ID, the snow removal conditions of a plurality of snowplows can be dynamically drawn on the map.
Acquiring map information may be an aspect of storing map information in a server device in advance and extracting it, or an aspect of acquiring map information available on the web instead of the server device. There may be.
Sending includes, for example, a mode in which data is directly transmitted to the server device, and a mode in which information is stored on the cloud server so that the server device can retrieve the data. Similarly, receiving is from a snowplow. In addition to the mode of receiving data directly, it also includes taking out information stored on the cloud server.
The created snow removal situation map may be stored in a server device, and the snow removal situation map output means may output the stored snow removal situation map.

  The snow removal status confirmation system according to claim 2 is the snow removal status confirmation system according to claim 1, in which the snow plow or the snow bucket is lowered to the snow removal work position or the rotary blade rotates with respect to the execution information. It is characterized by using the information indicating that the snow removal work is being executed as a state where the snow is being removed.

  In other words, the invention according to claim 2 can automatically create and provide a snow removal situation map without paying special attention to the snowplow driver by using execution information linked to the operation of the snowplow. .

  The snow removal status confirmation system according to claim 3 is the snow removal status confirmation system according to claim 1 or 2, wherein information on when and at which point the snow was removed is based on an elapsed time from the snow removal work in the snow removal status map. It is characterized in that the information is displayed in different colors.

In addition, it is preferable that the snow removal section assumed in advance, that is, the snow removal scheduled section and the snow removal work completion area, are drawn on the map so as to be known. A mode in which a road is drawn thickly or color-coded can be cited.

  The snow removal status confirmation system according to claim 4 is the snow removal status confirmation system according to claim 1, 2, or 3, wherein the snow removal status map creation means is controlled to provide information on future snow accumulation prediction and / or for each road. The present invention is characterized by comprising map creation control means for creating a snow removal status map by adding the next snow removal scheduled time and / or the working speed of the snowplow.

  That is, the invention according to claim 4 can provide a system that further enhances convenience for road users. Note that the snow forecast information refers to information such as the amount of snow, the amount of accumulated snow, and the snow quality. Information published by the Japan Meteorological Agency, etc. can be used as appropriate. The working speed of the snowplow will be separately incorporated into the snow removal information.

  ADVANTAGE OF THE INVENTION According to this invention, the system which can confirm a snow removal condition simply can be provided.

It is a conceptual diagram of the snow removal condition confirmation system of this invention. It is a functional block diagram of the snow removal condition confirmation system of this invention. It is an example of the snow removal condition map provided by the snow removal condition confirmation system of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram of a snow removal status confirmation system of the present invention. FIG. 2 is a functional block diagram of the snow removal status confirmation system of the present invention. FIG. 3 is an example of a snow removal status map provided by the snow removal status confirmation system of the present invention.

  The snow removal status confirmation system 1 includes a snow removal vehicle 10 and a server device 20.

  The snowplow 10 includes a snow plow (snow removal board) 11 that is lowered during snow removal work, and the vehicle body includes a GPS unit 12, a snow removal work detection unit 13, an information processing unit 14, a communication unit 15, Have

  The GPS unit 12 acquires position information about where the snowplow 10 is located. This superimposes the map data to show where you are working, and where you are, or where you are moving, as information that your employer should know even when you are not working. It can be acquired.

  The snow removal work detection unit 13 detects whether or not the snow plow 11 has been lowered to the snow removal work position, and creates information that the snow removal vehicle 10 is removing snow when it is lowered. On the other hand, when it is not lowered, information is generated that the snowplow 10 is not removing snow (simply traveling). Here, this information on whether or not snow removal work is being performed is referred to as execution information.

  The information processing unit 14 creates snow removal information, which is a set of position information, time information, execution information, and snowplow ID, every minute. The ID of the snowplow can be paraphrased as the ID of the communication unit 15, but in any case, it is assumed that it is uniquely determined in relation to other snowplows. As a result, even if there are multiple snowplows, such as a snowplow on the climbing lane and a snowplow on the descending lane, the execution information can be recognized separately and the execution information is not complicated. Proper provision is possible.

  The communication unit 15 transmits snow removal information to the server device 20. Although the transmission mode is not particularly limited, for example, data communication using a 3G line can be employed.

  Next, the server device 20 will be described. The server device 20 includes a snow removal information receiving unit 21, a map information acquisition unit 22, a snow removal status map creation unit 23, a map creation control unit 24, and a snow removal status map output unit 25.

The snow removal information receiving unit 21 sequentially receives snow removal information from the communication units 15 of each of the plurality of snow removal vehicles. The communication method between the communication unit 15 and the snow removal information receiving unit 21 is not particularly limited. For example, it may be a client / server model or a peer-to-peer model. Data exchange may be performed via email.
Examples of hardware for constructing the snow removal information receiving unit 21 include a network interface card, OS, and RAM of the server device 20.

The map information acquisition unit 22 acquires map information including roads. In the present embodiment, map data already stored in the hard disk drive of the server device 20 is used, and the map information acquisition unit 22 extracts information from the hard disk drive.
The map information acquisition unit 22 can be constructed by installing an extraction program as appropriate. Note that this map information is not mere image data, but information including the latitude and longitude of each point around the road.

The snow removal status map creation unit 23 represents the road section where snow has been removed thickly based on the snow removal information received by the snow removal information reception unit 21 with respect to the map information acquired by the map information acquisition unit 22, and from the snow removal work A snow removal situation map that is a color-coded map according to the elapsed time of is created. In this embodiment, since data is updated every minute, the position between the previous (1 minute ago) snowplow position (latitude / longitude) and the current snowplow position (latitude / longitude) on the map is displayed. The line is thick with a predetermined color.
Further, the map creation control unit 24 controls the snow removal status map creation unit 23 to add future snow accumulation prediction information, the next scheduled snow removal time, and the working speed of the snowplow to the snow removal status map. It is possible to determine whether the road should be used as planned, shifted in time, or detoured in consideration of the predicted snowfall and the next scheduled snow removal time. In addition, since the speed of work of snow plows is generally low, traffic congestion tends to occur depending on the time of day. It is possible to determine whether or not to detour.
The snow removal status map creation unit 23 and the map creation control unit 24 can be constructed by appropriately installing a map creation program.

The snow removal status map output unit 25 outputs the snow removal status map created by the snow removal status map creation unit 23 and the map creation control unit 24 so as to be viewable on the website. Specifically, in the present embodiment, the files are sequentially uploaded to a website as an html format file. As a result, a user such as a driver can view the real-time snow removal status with his / her terminal device such as a PC, a smartphone, or a tablet.
The snow removal status map output unit 25 can be constructed by, for example, the OS of the server device 20 or a network interface card.

  The extraction program, the map creation program, and other programs necessary for constructing the system are appropriately created as a component program of the snow condition confirmation program and installed in the server device.

An example of a snow removal status map is shown in FIG. As is clear from the figure, the snow removal status map
1) Map 2) Road 3) Road where snow was removed (bold)
4) Color-coded display (within 30 minutes of snow removal = green, 30 to 60 minutes after snow removal = blue, more than 60 minutes after snow removal = red)
5) Update time 6) Future snow cover forecast 7) Next scheduled snow removal time for each road 8) The speed of the snow plow during the snow removal work is drawn.
The figure can be appropriately enlarged and reduced, and when enlarged (detailed map), the above information is drawn in more detail (within 10 minutes after snow removal = flashing green, 10 minutes after snow removal) 20 minutes = green, 20 to 30 minutes after snow removal = dark green.

  As described above, according to the present invention, it is possible to easily check the snow removal status, so that drivers who have to use it can make judgments of the status one after another. Or detouring, it is very convenient, leading to the prevention of stuck and accidents.

The present invention is not limited to the above example.
The type of snowplow may be a snow bucket type, or may be a type in which rotating teeth are appropriately interposed. In the case of the snow bucket type, it is determined that the snow is being removed by detecting that the snow bucket is descending in the same manner as the snow plow type. However, since the snow bucket may be used up and down frequently, it is necessary to detect that the snow bucket has not dropped for a certain period of time and determine that snow removal is complete (while snow removal is in progress). preferable. In the case of the rotating tooth type, since it may be idle, it is determined that the snow removal operation is being performed when the rotation reaches a certain torque. In the case of a snowplow of a type in which rotating teeth and snow plows or snow buckets are mixed, it is determined that snow removal is being performed based on the lift information.
In addition to this, execution information is constructed based on manual operation start button / work end button presses and lighting information on the rotating lamps located on the top of the vehicle indicating that snow removal work is in progress, without being linked to lifting or rotating. You may do it. In particular, when a button is pressed, the introduction cost is low, which is preferable.

  In the present invention, since snowplows can be distinguished from each other by ID, the present invention is not limited to two vertical lines, and it is naturally possible to create a map reflecting snow removal information of a large number of snowplows.
