Description

  The present invention relates to a cross wind warning display / alarm device for preventing a car from being shaken by a cross wind placed in a place or in a mountain from a tunnel and driving unstable.

  Conventionally, various types of wind warning devices have been proposed. For example, the wind warning device described in Patent Document 2 (see FIG. 1) is a generator that generates power using the rotational force of a windmill. And a battery for charging electricity generated by the generator, and a display unit that is turned on using the power from the battery or the generator and displays a warning about the wind, but this is limited to the side wind It is not correspondence.

  However, these conventional wind alarm devices described in Patent Documents 2 and 3 each have a display unit for cautioning wind, but this display unit is installed only on a support column equipped with wind measuring devices. There is a problem that it is impossible to alert a car driver from a distance or at a remote point in the tunnel. That is, when a plurality of cars are running continuously, the above-mentioned alerting is not meaningful for the driver of the rear car behind the front car.

  In addition, vehicles that run on roads, especially those that run in narrow mountainous areas, or vehicles that are about to go out of the tunnel from inside the tunnel, receive a strong crosswind and take the handle and react to this There was a problem that it was easy to lead to driving mistakes such as sudden switching.

  Further, considering the influence of wind on the car, it is mainly the cross wind on the road and it is only necessary to target the wind speed in the vertical direction of the cross wind. If there is a wind direction sensor or a wind speed sensor that moves according to the direction of the wind, there is a part that has a movement such as rotation, so that long-term operational reliability is reduced and it is likely to break down or break There was a problem.

  Sometimes, as a wind sensor, the use of ultrasonic propagation time or the Doppler effect eliminates the need for moving parts, so the long-term operational reliability is high and safety should be ensured. Suitable for installation in.

  For example, various devices for obtaining the wind speed from the influence of the wind speed on the propagation time of the ultrasonic wave have been proposed, and a large number of devices have been disclosed in the patent literature. There are two pairs of ultrasonic transmitters and receivers that are appropriately spaced apart.

  Therefore, in order to solve the above-mentioned problems, the present invention has a long-term operational reliability due to the small number of moving parts, and can determine the crosswind component of the wind speed, away from the crosswind measurement point. The purpose of the present invention is to provide a crosswind warning display / alarm device that can alert a driver of a wind at a forward location even to a driver of a vehicle at a position where the measurement point cannot be directly viewed.

  In order to achieve this object, the crosswind warning display / alarm device of the first device has one or more pairs of ultrasonic transmitters and ultrasonic receivers facing each other at a desired distance.

Wind turbulence reduction means for reducing wind turbulence occurring between them is provided.

  The cross wind warning display / alarm device of the third device is the cross wind warning display / alarm device of the second device, wherein the wind turbulence reducing means is between the pair of the ultrasonic transmitter and the ultrasonic receiver. The distance between the ultrasonic transmitter and the ultrasonic receiver is a streamlined shape, or the ultrasonic wave is separated from the distance necessary to reduce the influence of turbulent flow. A line segment connecting the pair of the transmitter and the ultrasonic receiver is inclined with respect to the direction of the crosswind component.

  The cross wind warning display / alarm device of the fourth device is the cross wind warning display / alarm device of any one of the first to third devices, wherein the pair of the ultrasonic transmitter and the ultrasonic receiver is an ultrasonic wave. The transmitter has an ultrasonic reception function in addition to the ultrasonic transmission function, and the ultrasonic receiver has an ultrasonic transmission function in addition to the ultrasonic reception function.

  According to the crosswind warning display / alarm device of the fourth device, when measuring the crosswind component, the ultrasonic transmitter and the ultrasonic receiver that are paired with each other can transmit ultrasonic waves. The ultrasonic receiver can receive and transmit ultrasonic waves. That is, a pair of an ultrasonic transmitter and an ultrasonic receiver is a pair of transmission / reception devices having both ultrasonic transmission / reception functions. For this reason, when the direction of the crosswind component is the same as the direction in which the ultrasonic wave is transmitted, and the opposite direction is the minus direction, when measuring the crosswind component from the plus direction or the minus direction, You will be able to make that measurement.

It is the figure which showed the modification of the wind detection means shown in FIG.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a view showing a state in which a cross wind warning display / alarm device 100 according to an embodiment of the present invention is installed inside and outside a tunnel.

  As shown in FIG. 1, the cross wind warning display / alarm device 100 is for alerting the wind outside the tunnel. This crosswind warning display / alarm device 100 is installed on the shoulder 602 of the road 601. A display / alarm means 130B is installed in the tunnel. For this reason, the cross wind outside the tunnel can be recognized from a remote point without facing the outside of the tunnel 600, and safety can be secured with a margin.

  FIG. 2 is a block diagram of the crosswind warning display / alarm device 100. In particular, FIG. 2 (a) is a diagram showing the overall configuration (including the display / alarm means 130B), and FIG. 2 (b). These are the enlarged views of the wind detection means attached to the support body 150, FIG.2 (c) is the block diagram which showed the electrical structure.

  As shown in FIG. 2 (a), the cross wind warning display / alarm device 100 includes a wind detection means 110, a control means 120, a display / alarm means 130, and a power source 140 serving as a driving power source for these. And a columnar support 150 to be attached. The support 150 is necessary but may be considered separately from the configuration.

  As shown in FIG. 2B, the wind detection unit 110 includes two pairs of an ultrasonic transmitter 111A and an ultrasonic receiver 111B that receive the ultrasonic waves, which are separated from each other for a desired time. An ultrasonic transmitter 111A and an ultrasonic receiver 111B are attached to a support arm 112 that intersects at a desired angle, and an extending portion 113 extends from the intersecting portion of the support arm 112 toward the support 150. A base end portion of the extending portion 113 is fixed to the ring body 114, and the ring body 114 is rotatably fitted on the outer periphery of the support body 150.

  The extending portion 113 includes a tubular or rod-shaped fixed shaft portion 113B extending in a direction perpendicular to the support body 150 from the ring body 114, and fits around the fixed shaft portion 113B and around the central axis of the fixed shaft portion 113B. A rotating shaft portion 113A having a rotatable rod shape or tube shape, and a support arm 112 is attached to the rotating shaft portion 113A.

  The ring body 114 has a fixture A115 for fixing the ring body 114 at a desired position with respect to the support body 150. Further, between the rotation shaft portion 113A and the fixed shaft portion 113B in the extending portion 113, the rotation shaft portion 113A is rotated at a desired rotation angle with respect to the fixed shaft portion 113B, that is, at an angle with respect to the cross wind of the ultrasonic transceiver 111. A fixing tool B116 for fixing is provided.

  As shown in FIG. 2C, the control / calculation means 120 includes a wind speed / cross wind component calculator 121, a threshold discriminator 122, a wireless communication device 123, and a controller 124 that controls these operations. I have. The wind speed / cross wind component calculator 121 receives the ultrasonic transmission time information input from the wind detection means 110 and calculates a cross wind component perpendicular to the road where the present apparatus 100 is installed and parallel to the road surface. The control / calculation unit 120 also includes a storage device that stores control parameters.

  More preferably, when a component perpendicular to the road surface is also calculated, it is possible to obtain a lateral wind speed acting on the vehicle and an upward wind speed. In addition, since the component in the traveling direction of the vehicle has little influence on the danger during driving, the necessity for measurement is small.

  Here, since the threshold value is set in advance as the limit value of the lateral wind speed of the wind speed, preferably the upward wind speed, if this value is compared with the actually measured value, an alarm output is output if the actually measured value is large. It will be.

  This alarm output is transmitted to the display / alarm unit 130A installed on the support 150 by wire, and is transmitted to the display / alarm unit 130B installed in the remote tunnel through the wireless communication device 123. Is done.

  For this reason, even if there is a car running in the back of the tunnel and there is a car ahead and the field of view is obstructed, the display / alarm means 130B can recognize the cross wind attention in advance and can handle it with a margin.

  The display / alarm means 130 receives the output from the control / calculation means 120, and when the cross wind is larger than a predetermined threshold (or may be “when it is equal to or greater than the threshold”), the character “caution on cross wind” is displayed. (Refer to FIG. 2 (a).) Indication of an illustration or the like that the car is blown by the wind, and in some cases it is notified by sound. As described above, there are the display / alarm means 130A installed on the support 150 and the display / alarm means 130B installed in a remote place such as in a tunnel.

  As shown in FIG. 2A, the display / alarm means 130 includes a display 131 and a fixture A132 for supporting the display 131 on a support 150 or the like. The transmission of the signal from the control / calculation unit 120 to the display / alarm unit 130 can be performed by wire or wirelessly for those installed at remote locations.

  The power supply 140 can be supplied in a wired manner from a commercial power supply, but in this example, a solar battery 141 is used. The solar battery 141 is supported on the support body 150 by a fixture B142. Note that a storage battery for charging is connected to the solar battery 141. For this reason, it is possible to supply power from the power source 140 using the power charged in the storage battery by using the solar battery 141 even at night and on a sunny day.

  The storage battery may be integrated with the control / calculation means. However, such a storage battery is not necessarily provided.

  FIG. 3 is an enlarged view showing a modified example (second embodiment) of the wind detecting means in the cross wind warning display / alarm device 100. As shown in FIG. 3, in the extending portion 113 of the second embodiment, the axial direction of the fixed shaft portion 113B and the axial direction of the rotating shaft portion 113A intersect at a right angle, and the distal end portion of the extending portion 113 is viewed from the side. It has a form bent into an L shape.

  Here, the fixed shaft portion 113B extends in a direction perpendicular to the axial direction of the support body 150, and the rotating shaft portion 113A extends from the distal end portion of the fixed shaft portion 113B to the axial direction of the support body 150 (FIG. 3). In this case, the ultrasonic transmitter / receiver 111 is rotatably attached with the rotation shaft portion 113A as a rotation center axis.

  As described above, in the second embodiment shown in FIG. 3, the ultrasonic transceiver 111 is attached so as to be rotatable around an axis perpendicular to the support 150 in the first embodiment shown in FIG. What has been changed is to attach the surface of the ultrasonic transceiver 111 so as to be rotatable around an axis parallel to the axial direction of the support 150.

  In addition, according to the wind detecting means 110 of the second embodiment, in addition to the transverse wind component perpendicular to the traveling direction of the road in the horizontal plane, the wind speed of the component in the traveling direction of the road can be obtained. From the viewpoint of safe driving, the impact on the car is considered to be small. However, an alarm display may be performed based on the wind speed component in the traveling direction as necessary.

  4 and 5 are explanatory views showing an arrangement example of the wind detection means of the cross wind warning display / alarm device shown in FIG. 2 or 3 with respect to the cross wind direction. In addition, the dashed-dotted line in a figure is a straight line which connects the ultrasonic transmitter 111A and the ultrasonic receiver 111B which make a pair, and the arrow in a figure has shown the cross wind direction.

  In the arrangement example shown in FIG. 4A, the wind detection unit 110 has two pairs of ultrasonic transmitters 111 </ b> A and ultrasonic receivers 111 </ b> B in which the first pair is in the crosswind direction (the arrow direction in the figure). The second pair faces in a direction parallel to the crosswind direction. For this reason, either the second pair of ultrasonic transmitters 111A or the ultrasonic receivers 111B may disturb the flow of the cross wind measured by the first pair and make a turbulent state.

  On the other hand, according to the arrangement example shown in FIG. 4B, the arrangement shown in FIG. 4A is rotated by 45 ° on the paper surface of FIG. Since the straight line connecting the ultrasonic transmitter 111A and the ultrasonic receiver 111B is 45 ° with respect to the crosswind direction, the turbulent flow portion is in the vicinity of the ultrasonic transmitter 111A or the ultrasonic receiver 111B. Therefore, there is an advantage that the influence on the measurement result is small.

  By the way, in any of the arrangement examples shown in FIG. 4, the pair of the ultrasonic transmitter 111A and the ultrasonic receiver 111B out of the two pairs of the ultrasonic transmitter 111A and the ultrasonic receiver 111B are connected. The straight line connecting the second pair of the ultrasonic transmitter 111A and the ultrasonic receiver 111B intersects the straight line at a right angle, but the wind component in the direction perpendicular to the road direction, that is, the cross wind component. Is not limited to the case where the two straight lines intersect at right angles as described above. For example, if the relative intersection angle between the two straight lines is known, the crosswind component is calculated. can do.

  Here, in the two arrangement examples shown in FIG. 5, the straight line connecting the first pair of devices 111A and 111B and the straight line connecting the second pair of devices 111A and 111B are relative to each other for any of the wind detection means 110. The typical angle difference is 45 °.

  For example, in the arrangement example shown in FIG. 5A, one of the straight lines connecting the two pairs of devices 111A and 111B is perpendicular to the crosswind direction, and in the arrangement example shown in FIG. The arrangement shown in FIG. 5 (a) is the arrangement obtained by rotating 22.5 ° on the paper surface of FIG. In particular, according to the arrangement example of FIG. 5B, there is an advantage that the frontage with respect to the cross wind becomes wider and the portion where turbulent flow is generated is smaller than the arrangement example of FIG.

  FIG. 6 is a view showing a modification (third embodiment) of the wind detecting means 110 shown in FIG. In addition, the dashed-dotted line in a figure is a straight line which connects the ultrasonic transmitter 111A and the ultrasonic receiver 111B which make a pair, and the arrow in a figure has shown the cross wind direction.

  As shown in FIG. 6, the wind detection unit 110 of the third embodiment includes a support arm 112 formed in a streamlined manner to avoid a shake or turbulent flow of the support 150. Thus, since the support arm 112 has a streamline shape, the influence of the turbulent flow is reduced.

  If the structure does not interfere with the wind passage, turbulent flow is unlikely to occur. Therefore, it is also effective to reduce the attachment tip of the support arm 112 to which the ultrasonic transmitter 111A and the ultrasonic receiver 111B are attached. Further, the ultrasonic transmitter 111 </ b> A itself or the ultrasonic receiver 111 </ b> B itself may be formed in a streamline shape and attached to each tip portion of the support arm 112.

  By the way, according to each of the above-described embodiments, as the wind speed increases, the turbulent flow caused by the ultrasonic transmitter 111A, the ultrasonic receiver 111B, and the support arm 112 increases, and as a result, the transmission of ultrasonic waves has an effect. The wind speed measurement accuracy may be reduced.

  For this reason, in each embodiment, in consideration of the measurement range of the target wind speed, the influence of turbulent flow is reduced between the ultrasonic transmitter 111A and the ultrasonic receiver 111B within the measurement range. It is necessary to improve the measurement accuracy of the wind speed by separating the distance more than necessary.

  As described above, according to the cross wind warning display / alarm device of each of the above embodiments, it is possible to know in advance the cross wind, such as where it exits a highway tunnel, and so on. This is very convenient for industrial use.

  As a modification of the above embodiment, the above-described ultrasonic transmitter may have the function of an ultrasonic receiver, and the above-described ultrasonic receiver may have the function of an ultrasonic transmitter. You may have. That is, a pair of an ultrasonic transmitter and an ultrasonic receiver that are paired with each other may be a pair of ultrasonic transmitting and receiving apparatuses that can transmit and receive ultrasonic waves. In other words, if the direction of the crosswind component is the same as the direction in which the ultrasonic wave is sent out, the plus direction is the minus direction.If the opposite direction is the minus direction, when measuring the crosswind component, either from the plus direction or from the minus direction. The measurement can be made, and the influence of the atmospheric temperature can be offset.
