Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a bridge according to an embodiment of the present invention. FIG. 1 shows a side view of the bridge.

As shown in FIG. 1, the bridge 1 is installed between the land L1a and the land L1b. The bridge 1 includes abutment 1a, 1b, a pier 1c, a main girder 2a, 2b, a deck 3a, 3b, a ground cover 4a, 4b, a balustrade 5a, 5b, and a lighting column (in the appendix of the present invention). It has (corresponding) 6a and 6b. The acceleration sensor 11 and the control device 12 are installed on the floor slab 3a.

The abutment 1a is installed adjacent to the land L1a, for example. The abutment 1b is installed adjacent to the land L1b, for example. The pier 1c is installed between the abutments 1a and 1b.

The main girder 2a is installed above the abutment 1a and the pier 1c. The main girder 2b is installed above the abutment 1b and the pier 1c.

The floor slab 3a is installed above the main girder 2a. The floor slab 3b is installed above the main girder 2b.

The ground cover 4a is installed on the upper part of the floor slab 3a. The ground cover 4b is installed on the upper part of the floor slab 3b.

The balustrade 5a is installed above the ground cover 4a. The balustrade 5b is installed above the ground cover 4b.

The lighting column 6a is installed on the floor slab 3a. The lighting column 6b is installed on the floor slab 3b.

The acceleration sensor 11 is a side end of a bridge 1 (corresponding to the structure of the present invention) extending along the regulating direction of the moving direction regulating means for regulating the moving direction of the vehicle (corresponding to the moving body of the present invention). It is installed in the department. For example, the acceleration sensor 11 is installed at the end 3aa of the deck 3a in the width direction perpendicular to the direction along the regulation direction of the moving direction regulating means. At that time, the acceleration sensor 11 is installed at the end 3aa of the deck 3a so as to be at least a predetermined distance from the lighting column 6a which is an accessory on the deck 3a, which will be described in detail below. The moving direction regulating means for regulating the moving direction of the vehicle is, for example, the lane and the balustrades 5a and 5b shown on the floor slab 3a. The acceleration sensor 11 also includes an inertial sensor that outputs acceleration and angular velocity.

The control device 12 has a control unit 12a and a fixing means 12b. The control unit 12a receives acceleration data from the acceleration sensor 11 installed at the end 3aa of the deck 3a. The control unit 12a is equipped with an electronic device and analyzes the motion of the vehicle moving on the floor slabs 3a and 3b based on the acceleration data received from the acceleration sensor 11. For example, the electronic device of the control unit 12a analyzes the speed, traveling lane, weight, and the like of the vehicle moving on the floor slab 3a. In the following, the acceleration data output from the acceleration sensor 11 may be simply expressed as acceleration.

The control unit 12a includes a power supply unit such as a battery or a solar cell, and the electronic device of the control unit 12a is driven by the electric power of the power supply unit. The electronic device of the control unit 12a transmits the analyzed vehicle motion information to an information processing device on the network by using wireless communication such as a mobile phone network.

The fixing means 12b is, for example, a pole. One end of the fixing means 12b is fixed to the end 3aa of the deck 3a. Further, the control unit 12a is fixed to the other end of the fixing means 12b. As a result, the control device 12 is fixed to the floor slab 3a.

The control device 12 may transmit the acceleration detected by the acceleration sensor 11 to the information processing device on the network without analyzing the motion of the vehicle. Then, the information processing device on the network may analyze the movement of the vehicle on the floor slabs 3a and 3b.

Further, at least one acceleration sensor 11 is installed for one bridge 1. Therefore, the accelerometer 11 may be installed at the end 3ba of the deck 3b. In this case, the acceleration sensor 11 is installed at a predetermined distance from the lighting column 6b.

Further, the acceleration sensor 11 may be installed at the end portion 3aa of the floor slab 3a and the end portion 3ba of the floor slab 3b. In this case, the acceleration sensor 11 installed at the end 3aa is installed at a predetermined distance from the illumination column 6a, and the acceleration sensor 11 installed at the end 3ba is installed at a predetermined distance from the illumination column 6b.

FIG. 2 is a view taken along the line AA of FIG. In FIG. 2, the same ones as those in FIG. 1 are designated by the same reference numerals.

As shown in FIG. 2, three main girders 2a, 2aa, and 2ab are installed on the upper part of the pier 1c. The deck 3a is installed above the three main girders 2a, 2aa, and 2ab.

The ground covers 4a and 4aa are the upper surfaces of the deck 3a and are installed in the vicinity of the end 3aa. The balustrades 5a and 5aa are installed above the ground coverings 4a and 4aa. The lighting columns 6a and 6aa are the upper surfaces of the floor slab 3a and are installed in the vicinity of the end 3aa.

The acceleration sensor 11 is installed at the end 3aa of the deck 3a. The end portion 3aa is, for example, a side surface of the floor slab 3a in a direction along the regulating direction of the moving direction regulating means. The acceleration sensor 11 may be installed at the lower end of the floor slab 3a in a direction along the regulation direction of the movement direction regulating means of the floor slab 3a. One end of the fixing means 12b of the control device 12 is fixed to the end 3aa of the deck 3a.

FIG. 3 is a diagram illustrating an example of bending of the floor slab 3a. FIG. 3 shows a perspective view of the floor slab 3a shown in FIGS. 1 and 2 cut at the central portion. The position P1 shown in FIG. 3 indicates the center of the end portion 3aa of the deck 3a.

When the vehicle passes over the floor slab 3a, the deck 3a bends downward due to the load ld of the vehicle. Since the position P1 is the position farthest from the abutment 1a and the pier 1c, a change in the vertical position (position on the x-axis) of the deck 3a is likely to appear larger than other positions. Further, since the position P1 is the end portion 3aa of the floor slab 3a, the inclination of the floor slab 3a with respect to the horizontal direction (inclination of the z-axis) tends to appear larger than that of other positions. Therefore, when the acceleration sensor 11 is attached to the position P1 of the deck 3a, the acceleration in the vertical direction and the acceleration in the width direction of the deck 3a caused by the passage of the vehicle can be clearly detected. That is, it is desirable that the acceleration sensor 11 is installed at the central portion (including the substantially central portion) of the end portion 3aa of the floor slab 3a. The y-axis and z-axis accelerations are gravity components due to the inclination of the deck 3a.

On the other hand, accessories such as a lighting column 6a are generally attached to the floor slab 3a. The accessory has a shape including, for example, a columnar portion extending in the vertical direction from the floor slab 3a of the bridge 1. Accessories include lighting columns, sign columns, signal columns, handrail columns, balustrades, and the like. When the accessory sways due to wind or the like, the floor slab 3a also vibrates around a fixed point of the accessory to the floor slab 3a, and the acceleration sensor 11 also detects the acceleration due to the vibration. The acceleration of the floor slab 3a generated by the wind or the like is noise in the motion analysis of the vehicle, and it is desirable that it is not detected by the acceleration sensor 11. That is, the acceleration sensor 11 should be installed away from the accessories that sway due to the influence of wind or the like.

Therefore, the acceleration sensor 11 is installed near the central portion (position P1) of the end portion 3aa of the deck slab 3a and at least a predetermined distance from the accessories on the deck slab 3a.

The predetermined distance between the accessory and the acceleration sensor 11 is proportional to the projected area of the accessory from the horizontal direction. This is because the larger the projected area, the larger the floor slab 3a vibrates when the accessory sways. That is, the larger the projected area of the accessory, the farther the accelerometer 11 is installed from the accessory.

FIG. 4 is a diagram illustrating an example of the projected area of the accessory. FIG. 4 shows a lighting column 6a, which is an accessory of the floor slab 3a. The projected area of the illumination column 6a is, for example, the shadow projected on the screen S1 behind the illumination column 6a when the illumination column 6a is illuminated from a direction perpendicular to the regulation direction of the movement direction regulating means. The area.

The larger the projected area of the lighting column 6a, the larger the moment given to the floor slab 3a. That is, the larger the projected area of the lighting column 6a, the greater the influence of the vibration on the floor slab 3a when it is shaken by the wind.

Therefore, the predetermined distance between the accessory and the acceleration sensor 11 is set to be proportional to the projected area of the accessory from the horizontal direction as described above. That is, the predetermined distance is calculated using the projected area of the accessory from the horizontal direction.

The predetermined distance may be calculated using the projected area of the accessory from the horizontal direction, the size of the deck 3a, the material (hardness) of the deck 3a, and the like.

Further, the projected area of the accessory may be the area of the shadow projected on the screen behind the accessory when light is applied from a direction parallel to the regulation direction of the moving direction regulating means. For example, the projected area of the accessory may be the area of the shadow projected on the screen behind the illumination column 6a by shining light on the illumination column 6a from the front side to the back surface of the paper surface of FIG.

Further, the projected area of the accessory is illuminated from the direction perpendicular to the regulating direction of the moving direction regulating means, the projected area when the lighting column 6a is illuminated with light, and the direction parallel to the regulating direction of the moving direction regulating means. It may be the total area with the projected area when the pillar 6a is exposed to light.

Further, the predetermined distance may be set larger in proportion to the projected area from the direction perpendicular to the extending direction of the bridge 1 even in the horizontal direction. This is to suppress the influence of the deformation of the bridge due to the wind from the direction perpendicular to the extending direction.

FIG. 5 is a diagram illustrating an installation example of the acceleration sensor. FIG. 5 shows a part of the bridge 1 shown in FIG. In FIG. 5, the same reference numerals as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. The arrow C1 shown in FIG. 5 indicates the central portion of the end portion 3aa of the deck slab 3a.

The acceleration sensor 11 is installed at least a predetermined distance from the lighting column 6a which is an accessory on the floor slab 3a. At that time, the acceleration sensor 11 is the center of the end portion 3aa of the first region and the second region of the end portion 3aa of the floor slab 3a with the illumination column 6a as an accessory on the floor slab 3a as a boundary. It should be installed in the area including the part.

For example, the arrows A1 and A2 in FIG. 5 indicate a first region and a second region of the end portion 3aa of the floor slab 3a with the illumination column 6a as a boundary. Of these two regions, the second region indicated by the arrow A2 includes the central portion (arrow C1) of the end portion 3aa. Therefore, the acceleration sensor 11 is installed at least a predetermined distance from the illumination column 6a in the second region indicated by the arrow A2 at the end 3aa.

Specifically, it is assumed that the predetermined distance at which the acceleration sensor 11 should be separated from the illumination column 6a is “x1”. In this case, the accelerometer 11 is installed at least "x1" away from the illumination column 6a (for example, a fixed point of the illumination column 6a on the deck 3a) in the second region of the end 3aa indicated by the arrow A2. To do so. That is, the acceleration sensor 11 is installed so as not to be far from the central portion of the end portion 3aa (so as not to be installed in the first region indicated by the arrow A1).

In this way, since the acceleration sensor 11 is installed away from the accessory so that the influence of the shaking of the accessory is reduced, the influence of noise due to the accessory can be reduced. Further, since the acceleration sensor 11 is installed near the central portion of the end portion 3aa of the deck slab 3a, the acceleration of the deck slab 3a caused by the passage of the vehicle can be clearly detected. As a result, the control device 12 can appropriately analyze the movement of the vehicle moving on the deck.

In the acceleration sensor 11, when the lighting column 6a attached to the floor slab 3a and the central portion (arrow C1) of the end portion 3aa of the floor slab 3a are separated by a predetermined distance or more, the center of the end portion 3aa. Be installed in the department. For example, the arrow A3 shown in FIG. 5 indicates the distance between the lighting column 6a and the central portion of the end portion 3aa. When the distance indicated by the arrow A3 is a predetermined distance or more, the acceleration sensor 11 is installed at the center of the end portion 3aa indicated by the arrow C1.

Further, the control device 12 can be said to be an accessory of the floor slab 3a. Therefore, after the acceleration sensor 11 is installed at the end 3aa of the deck 3a, the fixing means 12b of the control device 12 (for example, the fixing point of the fixing means 12b to the end 3aa) is at least predetermined from the acceleration sensor 11. Install at a distance.

The predetermined distance between the acceleration sensor 11 and the control device 12 is proportional to the projected area of the control device 12, similar to accessories such as the lighting column 6a. That is, the larger the projected area of the control device 12, the farther away it is from the acceleration sensor 11. The predetermined distance between the acceleration sensor 11 and the control device 12 is calculated using the projected area of the control device 12 from the horizontal direction.

For example, the distance between the acceleration sensor 11 and the control device 12 is assumed to be "x2". In this case, the control device 12 is installed at least "x2" away from the accelerometer 11 as shown in FIG.

The predetermined distance between the acceleration sensor 11 and the control device 12 is calculated using the projected area of the control device 12 from the horizontal direction, the size of the deck 3a, the material (hardness) of the deck 3a, and the like. May be good.

FIG. 6 is a flowchart showing an example of installation of the acceleration sensor 11. First, the projected area of the lighting column 6a installed on the floor slab 3a is calculated (step S1).

Next, using the projected area calculated in step S1, the distance (predetermined distance) that the acceleration sensor 11 should be separated from the illumination column 6a is calculated (step S2).

Next, assuming that the acceleration sensor 11 is installed at the center of the end portion 3aa of the floor slab 3a, it is determined whether or not the lighting column 6a and the acceleration sensor 11 are separated by a predetermined distance calculated in step S2. (Step S3). When the lighting column 6a and the acceleration sensor 11 are separated from each other by a predetermined distance calculated in step S2 (“Yes” in S3), the process proceeds to step S4. If the lighting column 6a and the acceleration sensor 11 are not separated by a predetermined distance calculated in step S2 (“No” in S3), the process proceeds to step S5.

When it is determined in step S3 that the lighting column 6a and the acceleration sensor 11 are separated from each other by the predetermined distance calculated in step S2 (“Yes” in S3), the acceleration sensor 11 is attached to the end portion 3aa of the deck 3a. It is installed in the central part (step S4).

When it is determined in step S3 that the lighting column 6a and the acceleration sensor 11 are not separated from each other by the predetermined distance calculated in step S2 (“No” in S3), the acceleration sensor 11 is attached to the end portion 3aa of the floor slab 3a. The lighting column 6a and the acceleration sensor 11 are installed so as to be separated from the central portion by at least a predetermined distance calculated in step S2 (step S5). That is, the acceleration sensor 11 is installed in a region including the central portion of the end portion 3aa among the first region and the second region of the end portion 3aa of the floor slab 3a with the illumination column 6a as the boundary. do.

Next, the projected area of the control device 12 is calculated (step S6).

Next, using the projected area of the control device 12 calculated in step S6, the distance (predetermined distance) that the control device 12 should be separated from the acceleration sensor 11 is calculated (step S7).

Next, the control device 12 is installed at the end 3aa of the deck 3a at least at a predetermined distance calculated in step S7 (step S8).

The control device 12 may be installed on land L1a and L1b so as not to give vibration to the floor slab 3a. Alternatively, the control device 12 may be installed at the end 3aa without the fixing means 12b. For example, the control device 12 may be installed at the end 3aa of the bridge 1 extending along the regulation direction of the movement direction regulating means for regulating the movement direction of the vehicle.

As described above, the acceleration sensor 11 is at least predetermined with the lighting column 6a on the floor slab 3a, which is the end portion 3aa of the floor slab 3a in the direction along the regulation direction of the movement direction regulating means for regulating the movement direction of the vehicle. Install at a distance. As a result, the influence of the shaking caused by the illumination column 6a of the acceleration sensor 11 is suppressed, so that the motion of the vehicle moving on the floor slab 3a can be appropriately analyzed.

Further, the acceleration sensor 11 is installed in a region including the central portion of the end portion 3aa among the first region and the second region of the end portion 3aa with the illumination column 6a as an accessory as a boundary. As a result, the acceleration sensor 11 can clearly detect the acceleration of the floor slab 3a caused by the movement of the vehicle, so that the movement of the vehicle moving on the floor slab 3a can be appropriately analyzed.

Further, when the lighting column 6a, which is an accessory, and the central portion of the end portion 3aa of the floor slab 3a are separated by a predetermined distance, the acceleration sensor 11 is installed at the central portion of the end portion 3aa. As a result, the acceleration sensor 11 can clearly detect the acceleration of the floor slab 3a caused by the movement of the vehicle, so that the movement of the vehicle moving on the floor slab 3a can be appropriately analyzed.

Further, the distance between the acceleration sensor 11 and the illumination column 6a is proportional to the projected area of the illumination column 6a from the horizontal direction. As a result, noise due to the shaking of the illumination column 6a of the acceleration sensor 11 can be appropriately suppressed.

Further, the control device 12 that controls the acceleration sensor 11 is installed at a predetermined distance from the acceleration sensor 11. As a result, noise due to shaking of the control device of the acceleration sensor 11 can be suppressed.

The predetermined distance may be, for example, 1/5 of the length of the columnar portion of the illumination column 6a on the bridge 1 in the vertical direction.

Further, in the above, the predetermined distance at least separating the accessory from the acceleration sensor 11 is proportional to the projected area of the accessory from the horizontal direction, but is proportional to the length (height) of the accessory in the vertical direction.
