Concerning radio equipment, test equipment, test systems, and test methods.

[Description of prior art]
Conventionally, in order for the train driver onboard to check the status of the station platform, video data taken on the station platform is transmitted wirelessly using a radio (terrestrial radio), and then transmitted using a radio in the train (onboard radio). There is a wireless system for transmitting images that receives images and displays them on a monitor screen.
The on-board radio is attached to the ceiling of the driver's seat and communicates with the ground radio located near the platform at each station (for example, on the wall next to the tracks).
Regarding the train radio equipment used in the image transmission system, in addition to pre-operation inspections, periodic performance measurements are carried out.

[Schematic configuration of conventional radio equipment: Figure 9]
A schematic configuration of a conventional on-vehicle radio device (hereinafter referred to as a "radio device") will be described using FIG. 9. FIG. 9 is a perspective view showing a schematic configuration of a conventional radio device.
As shown in FIG. 9, a conventional radio device 30 includes a radio device main body 31 and a mounting bracket 32 provided on the top surface of the radio device main body 31.

The radio main body 31 is a communication device that includes a radio section inside a housing that performs processing associated with radio communication, and communicates with a terrestrial radio installed on a station platform or the like.
The mounting bracket 32 is a metal fitting for attaching the radio main body 31 to the ceiling of the driver's seat of the vehicle, and includes an upper surface portion that covers the top surface of the radio device main body 31 and a side surface portion that covers a portion of the left and right side surfaces of the radio device main body 31. It has a section.

A circular hole is formed in the center of the upper surface of the mounting bracket 32, and a mounting hole 321 for fixing the mounting bracket 32 to the ceiling is formed around the hole. The attachment hole 321 is formed in an elongated shape (elongated hole) so that the angle can be adjusted in the horizontal direction (left and right direction).
Furthermore, two mounting holes are formed on both sides of the mounting bracket 32 for fixing the radio main body 31 to the mounting bracket 32. Although not shown, the lower mounting hole is an elongated hole, and the angle of the radio main body 31 in the vertical direction (up and down direction) can be adjusted using the upper mounting hole as an axis.

When installing, first adjust the horizontal angle of the mounting bracket 32 and attach it to the ceiling of the driver's seat so that the radio main body 31 can perform good communication with the terrestrial radio. The main body 31 is attached and fixed to the mounting bracket 32 while adjusting the vertical inclination.

[Conventional test method: Figure 10]
A conventional test method will be explained using FIG. 10. FIG. 10 is an explanatory diagram showing a conventional test method. Here, "testing" includes inspections to confirm operation before train operation, and performance measurements to periodically check the performance of equipment.
As shown in FIG. 10, when testing the radio device main body 31 provided on the radio device 30 installed in the vehicle, a worker uses a portable tester (hereinafter referred to as a "tester"). 40) and stand at a specific distance (for example, 10 m) from the front of the radio 30, adjust the radio wave emission direction (orientation of the tester 40) so that the reception level is optimal, and then , measure the reception level of the on-board radio.

During normal inspection, the reception level is confirmed using a simple level lamp (not shown) mounted on the tester 40, but during performance measurement, in order to measure the reception level accurately, the , the measuring device 50 is connected to the testing device 40, and measurement is carried out.

The mounting position of the radio device 30 differs depending on the vehicle. In order to maintain good communication with ground radio equipment during operation, the direction of radio wave emission is adjusted for each vehicle, and the horizontal and vertical angles are slightly different for each vehicle.
Therefore, during inspection and performance measurement, it is necessary to change the direction of the tester 40 for each vehicle during temporary installation to match the direction of radio wave emission, which causes differences among workers and increases errors in measurement results.

In particular, in image transmission wireless communication devices, due to the characteristics of radio waves, they tend to travel in a straight line and have a narrow radiation area, which tends to lower the reception level and cause errors in performance measurements. Therefore, it is necessary to accurately align the radio wave emission direction of the tester 40 with the radio device main body 31, and it takes time to adjust the angle of the tester 40.

In conventional testing methods, changing the position or orientation of the tester 40 during performance measurement causes measurement errors, so the worker holding the tester 40 must remain stationary and maintain the same posture until the inspection is completed. Yes, it was a burden.

In addition, during inspection, two workers are required: one to check the monitor output image of the radio device body 31 inside the vehicle, and the other to operate the tester 40 outside the vehicle. Three workers are required including one to check the measuring device 50 connected to the measuring device 40.

[Schematic configuration of this test system: Figure 1]
The schematic configuration of this test system will be explained using FIG. 1. FIG. 1 is a perspective view showing the schematic configuration of this test system.
As shown in FIG. 1, this test system includes a radio device (this radio device) 10 that is attached to the driver's seat of a vehicle such as a train, and a portable test device that tests the radio device 10 (this test device). )20. In the embodiment, a case will be described in which the radio device 10 is attached to the driver's seat of a railway vehicle, but the present invention is not limited to this.
Here, like the conventional radio device 30, the radio device 10 is mounted on the ceiling of the driver's seat of a train vehicle in close proximity to the front transparent plate. The distance between the radio device 10 and the front transparent plate is approximately 10 cm.
Further, the front transparent plate is a general term for a protective member (windshield) that covers the front of a vehicle, and is made of a transparent member such as glass or acrylic.

The present radio device 10 includes a radio device main body 11, a mounting fitting 12, and an auxiliary metal fitting 13, which is a characteristic part of the present radio device 10.
The radio main body 11 is a communication device that performs wireless communication with a terrestrial radio, similar to the conventional radio main body 31 shown in FIG.
Further, the mounting fitting 12 is equivalent to the conventional mounting fitting 32. The configuration of the mounting bracket 12 will be described later.

The auxiliary bracket 13 is a characteristic part of this test system, and is fixed to the mounting bracket 12 so that the tester 20 faces the front of the wireless device 11 (radio wave emission surface, the front side in FIG. 1). It is to be kept as such. The auxiliary metal fitting 13 is provided with a plurality of protrusions for engaging with the main tester 20. The configuration of the auxiliary metal fitting 13 will be described later.

The tester 20 includes a tester main body 21 and a bracket 22.
The tester main body 21 is a portable tester, and communicates with the radio device main body 11 to test the radio device main body 11.
The bracket 22 is an engaging part that is a feature of this system, and is made of metal (for example, stainless steel) and is provided so as to protrude in a substantially U-shape across the left side, top, and right side of the tester main body 21. It is a plate-shaped member. The bracket 22 has a plurality of holes formed therein, and the tester 20 is held in front of the radio device 10 by engaging the holes with the protrusions of the auxiliary fitting 13 of the radio device 10. It is.
The thickness of the tester 20 is approximately 5 cm, and the thickness of the bracket 22 is approximately 2 mm.

[This tester is attached to this radio: Figure 2]
The state in which the test device 20 is attached to the radio device 10 will be explained using FIG. 2. FIG. 2 is a perspective view showing the tester 20 attached to the wireless device 10. As shown in FIG. In this system and this method, a test is conducted in the state shown in FIG.
As shown in FIG. 2, in the present tester 20, the surface of the tester main body 21 facing the present radio device 10 (the rear surface in FIG. 2) serves as a radio wave emitting surface.
Then, by engaging the bracket 22 of the main tester 20 with the auxiliary fitting 13 of the main radio 10, the radio wave emitting surface of the tester main body 21 faces and approaches the radio wave emitting surface of the radio main body 11. maintained in the state.

In other words, with this test system, tests can be performed with the tester and radio set facing each other in the optimal condition without the need for complicated angle adjustments of the tester. Since there is no need to hold the data, the work can be reduced and errors can be suppressed.

Furthermore, in this system, the testing device 20 can be installed in the driver's seat like the wireless device 10, so that the test can be carried out by one worker. Furthermore, even when measuring performance by connecting a measuring device to the tester 20, it can be carried out by one person. This makes it possible to conduct the test efficiently.

Here, the tester main body 21 holds test data (test data) similar to a conventional tester, and transmits the test data during a test. Data indicating the reception level is received and displayed on a reception level display section to be described later.
However, compared to the conventional tester 40, this tester 20 has an attenuator inserted because the distance to the radio equipment body 11, which is the device under test, is shorter, and the optimum condition is shown in FIG. Transmission levels are appropriately adjusted to allow accurate testing.

Similarly, since the communication distance of the radio device main body 11 is shorter during testing compared to the transmission and reception with the ground radio device in actual operation, the transmission level is set to be appropriate. For example, by externally switching the operation mode between "operation" and "test", it is possible to perform a test at an appropriate transmission level.
Appropriate transmission levels for the tester 20 and the wireless device 10 are determined in advance through experiments or simulations.

As described above, the radio device 10 is mounted on the ceiling of the driver's seat of a train vehicle at a distance of about 10 cm from the front transparent plate of the vehicle.
Therefore, during the actual test, the operator inserts the tester 20 from below the radio device 10 between the front transparent plate and the auxiliary metal fitting 13, and then inserts the tester 20 into the hole in the bracket 22 of the tester 20. It is attached by hooking it onto the protrusion of the auxiliary metal fitting 13.

[Configuration of mounting bracket 12 and auxiliary bracket 13: Figure 3]
Next, the configuration of the mounting bracket 12 and the auxiliary bracket 13 of the radio device 10 will be explained using FIG. 3. FIG. 3 is an explanatory diagram showing the configuration of the mounting fitting 12 and the auxiliary fitting 13.
As shown in FIG. 3, the mounting bracket 12 has a similar configuration to the conventional mounting bracket 32 shown in FIG. Four mounting holes 121 are formed for fixing to the ceiling. The attachment hole 121 is formed in an elongated shape (elongated hole) and allows horizontal angle adjustment.

Further, mounting holes 122a and 122b for fixing the radio device main body 11 to the mounting bracket 12 are formed on both sides of the mounting bracket 12. Here, the lower mounting hole 122b is a long hole, and the vertical angle of the radio main body 11 can be adjusted with the upper mounting hole 12a as an axis.

The auxiliary metal fitting 13 includes a substantially U-shaped front portion that is open downward, and left and right side portions.
A plurality of protrusions 131 that engage with the bracket 22 of the tester 20 are provided on the front surface. The installation position and length of the protrusion 131 are adjusted so that the radio wave emitting surface of the tester main body 21 is held at an appropriate distance from the radio main body 11 and parallel to the radio wave emitting surface of the radio main body 11. ing. The protrusion 131 will be described later.

Further, two mounting holes 132 for fixing the auxiliary metal fitting 13 to the radio main body 11 via the side surfaces of the mounting metal fitting 12 are formed on the left and right side surfaces of the auxiliary metal fitting 13. The mounting hole 132 is not a long hole.
Then, insert bolts (not shown) so as to pass through the mounting hole 132 of the auxiliary metal fitting 13 and the mounting holes 122a and 122b of the mounting metal fitting 12, and attach the side surface of the auxiliary metal fitting 13 to the side surface of the mounting metal fitting 12 and the radio device 11. Fixed to.
As a result, in the present radio device 10, the positional relationship between the radio device main body 11 and the auxiliary metal fitting 13 is fixed.

Furthermore, the auxiliary fitting 13 can be attached to the conventional radio device 30 shown in FIG. This configuration can be changed to 10 configurations.
After installing the auxiliary bracket 13, if it is necessary to adjust the vertical direction for communication with the on-board radio, loosen the lower bolt (fitted into the mounting hole 122b) and make the adjustment. It is possible to do so.

Note that, although the mounting fitting 12 and the auxiliary fitting 13 are described as separate structures here, they may be formed integrally.
In this case, even if the radio is operated with an upward or downward tilt, by mounting the radio vertically on the mounting bracket, the radio wave emitting surface of the tester 20 can be so that it is parallel to

[Protrusion 131 of auxiliary metal fitting 13: Fig. 4]
Next, the structure of the protrusion 131 of the auxiliary metal fitting 13 will be explained using FIG. 4. FIG. 4 is an explanatory view showing the structure of the protrusion 131 of the auxiliary fitting 13, in which (a) is a perspective view and (b) is a side view.
As shown in FIGS. 13(a) and 13(b), the protrusion 131 has a constricted portion 133 having a narrow diameter between the tip portion and the root portion.
As will be described later, by forming the constricted part 133, the mounting hole provided in the bracket 22 of the tester 20 fits into the constricted part 133 and becomes stable, and the tester 20 will not shift due to slight contact or vibration. This prevents it from coming off or coming off.
When the tester 20 is correctly attached to the projection 131 of the auxiliary metal fitting 13, the gap between the radio device body 11 and the tester body 21 is approximately 1 mm to 2 mm.

[Radio device configuration: Figure 5]
Next, the configuration of the radio main body 11 will be explained using FIG. 5. FIG. 5 is a perspective view of the radio device main body.
As shown in FIG. 5, the radio device main body 11 has almost the same configuration as the conventional radio device main body 31, and a circuit section that performs processing associated with wireless communication is provided inside a substantially rectangular parallelepiped housing. .
The surface on the near side of the figure is the radio wave emitting surface 114, and serves as a transmitting and receiving surface. This radio device 10 is installed so that the radio wave emitting surface 114 of the radio device main body 11 faces the front transparent plate of the driver's seat of the train.
Mounting holes 115 for fixing the mounting bracket 12 and the auxiliary bracket 13 are provided in the side surface, and the mounting bracket 12 and the auxiliary bracket 13 are fixed with bolts (not shown).

[Test device configuration: Figure 6]
Next, the configuration of the tester 20 will be explained using FIG. 6. FIG. 6 is a perspective view of the tester.
As shown in FIG. 6, in the tester 20, a chassis (board) on which circuit components necessary for testing and wireless communication are mounted is housed and fixed inside a thin case.
A bracket 22 is fixed to the board. In other words, the bracket 22 has a size and shape that allows it to reach not only the part visible from the outside but also the chassis inside the case.

The case of the tester 20 is composed of a front case and a back case, and handles 213 are provided on both side surfaces of the case on one side (referred to as the front case here). The handle 213 may be provided on the back case.
Approximately one-third of the upper portion of the front side of the case serves as a radio wave emitting surface 214.

Although not shown in the drawings, there is a part on the outer periphery of the upper one-third of the case on one side of the tester 20 (referred to as the back case here) for closing the case with a bracket 22 sandwiched therebetween. A notch is formed in the top to absorb the thickness. The cutout portion may be formed in the surface case.
As a result, the bracket 22 is tightly sandwiched and fixed between the front case and the back case.

The bracket 22 is provided with a mounting hole 221 that engages with the protrusion 131 of the auxiliary metal fitting 13 of the radio device 10.
The mounting hole 221 is formed at a position where it engages with the protrusion 131 when the tester main body 21 is correctly opposed to the radio device main body 11, and is further formed in a shape that makes it easy to engage and difficult to dislodge even with a slight vibration. ing.
The shape of the attachment hole 221 will be described later.

A reception level display section 215 is provided on the surface of the tester main body 21. The reception level display section 215 includes a plurality of LEDs, and the tester main body 21 lights up the LEDs in stages according to the reception level in the radio device main body 11 notified from the radio device main body 11. .

Here, when the tester 20 is attached to the radio 10, the reception level display section 215 is displayed so that the tester 20 is not hidden behind the radio 10 (so that it does not overlap with the radio 10). It is provided below the surface of the main body 21.
By providing the reception level display section 215 at this position, the worker conducting the test can visually check the reception level display section 215 of the tester main body 21 from the driver's seat side and check the reception level of the radio device main body 11. It is something that can be done.
Note that switches other than the reception level display section 215 are also provided at positions that do not overlap with the wireless device 10 during the test.

[Bracket mounting hole shape: Figure 7]
Next, the shape of the mounting hole 221 of the bracket 22 of the tester 20 will be explained using FIG. 7. FIG. 7 is an explanatory diagram showing the shape of the mounting hole of the bracket.
As shown in FIG. 7, the mounting hole 221 of the bracket 22 has a Daruma-shaped shape in which a lower hole 221a with a larger diameter and an upper hole 221b with a smaller diameter are connected.
This is to facilitate the installation work of the tester 20 and to ensure stable engagement with the radio device 10.

When attaching this tester 20 to this radio device 10, a worker holds the handle 213 of this tester 20 with both hands, inserts it between this radio device 10 and the front transparent plate of the train, and then inserts it into the bracket. 22 is engaged with the protrusion 131 of the auxiliary metal fitting 13, but since the engagement location is in the shadow of the wireless device 10, the worker cannot directly see the engagement location.

However, by making the mounting hole 221 of the bracket 22 into a Daruma shape, if the worker attempts to engage the bracket 22 with the auxiliary fitting 13 from slightly above the target position, the diameter of the pilot hole 221a is large. It can be engaged with the protrusion 131 relatively easily.
Furthermore, after engaging with the lower hole 221a, the tester 20 descends due to its own weight to a position where it engages with the protrusion 131 at the upper hole 221b. Since the upper hole 221b has a small diameter, the gap between the upper hole 221b and the protrusion 131 becomes narrow, preventing the tester 20 from shaking or coming off, allowing the test to be carried out in a stable state.

When removing the tester 20 from the wireless device 10, the operator lifts the tester 20 upward once so that the pilot hole 221a overlaps the protrusion 131, and then removes it.
By making the mounting hole 221 of the bracket 22 into such a shape, the tester 20 can be easily attached to and detached from the radio device 10, and can be prevented from being unintentionally removed. .

In this embodiment, the protrusion 131 is provided on the auxiliary metal fitting 13 of the radio device 10, and the mounting hole 221 is provided on the bracket 22 of the tester 20. 13 may be provided with a mounting hole, and the bracket 22 of the tester 20 may be provided with a protrusion.
In this case, the protrusion of the bracket 22 is formed to be inserted between the radio body 11 of the radio 10 and the mounting bracket 12, or between the upper part of the mounting bracket 12 and the ceiling.

[Example of guideline: Figure 8]
Next, an example of guidelines provided in the tester 20 will be described using FIG. 8. FIG. 8 is an explanatory diagram showing an example of a guideline.
As mentioned above, during the test, a worker inserts the tester 20 from below between the transmitter 10 and the front transmission plate of the train, and inserts the tester 20 between the bracket 22 and the transmitter 10 to support the radio device 10. Although the metal fittings 13 are engaged, the engaged part is hidden behind the radio and cannot be seen by the operator.

Therefore, in this tester 20, a guideline is provided to indicate how far a worker should lift the tester 20 to engage the tester 20.
As shown in FIG. 8, the guideline 218 is drawn as a line parallel to the short side of the tester main body 21 at about one-third from the top of the surface case of the tester main body 21. As shown in FIG.
The worker lifts the tester 20 to such an extent that the guideline 218 is hidden behind the radio device 10 and then engages the mounting hole 221 of the bracket 22 with the protrusion 131 of the auxiliary metal fitting 13.
Thereby, the work of installing the tester 20 can be facilitated.

Here, the guideline 218 is drawn as a single straight line connecting the long sides of the tester main body 21, but only the ends, only the center, etc., show a part of the guideline 218 in FIG. It may be. Moreover, it is not limited to a line, but may be a mark.
