JP7646151B2 - Hand stop detector, hand stop monitoring device using the same, and hand stop detector setting device - Google Patents

Description

The present invention relates to a hand stop detector, a hand stop monitoring device using the same, and a hand stop detector setting device. More specifically, the present invention relates to a hand stop detector that detects whether a hand stop is installed in a specified position between the rail and the wheel, and a hand stop monitoring device and a hand stop detector setting device using the same.

In recent years, there has been a demand for devices on railway vehicles, particularly maintenance cars, that can detect whether the handrails, which are wedge-shaped wheel-rolling prevention devices installed between the rails and the wheels, are in the correct position and provide a warning.

One such device is the hand brake forgetting prevention alarm device disclosed in Patent Document 1. This device is configured to prevent drivers from forgetting to install and remove the hand brakes not only when vehicles such as maintenance cars and railway cars are stopped, but also when the vehicles are moving. Here, maintenance and inspection work for railway facilities such as tracks is carried out by introducing a large number of maintenance cars onto the tracks during times such as at night when trains are not running, and each maintenance car shares the maintenance and inspection work for a specified section. In such cases, a measure to install hand brakes when the maintenance cars are stopped is widely adopted to prevent them from rolling.

In other words, when the maintenance vehicle stops and work is completed, if the hand stopper is not installed between the wheel tread of the maintenance vehicle and the rail, an operation is started to call attention to the installation of the hand stopper between the wheel tread of the maintenance vehicle and the rail, and the warning operation is stopped when the hand stopper is installed between the wheel tread of the maintenance vehicle and the rail. Also, when the maintenance vehicle is capable of traveling and the hand stopper is installed between the wheel tread of the maintenance vehicle and the rail, an operation is started to call attention to the removal of the hand stopper, and the warning operation is stopped when the hand stopper is stored in the storage box. In other words, the system is configured to call attention to the removal of the hand stopper when the maintenance vehicle is capable of traveling.

Another such device is the anti-rolling device disclosed in Patent Document 2. This device is configured to automatically issue an alarm if anti-rolling processing based on a prescribed operating procedure is not performed in a maintenance vehicle after the engine is stopped. In other words, a warning means that notifies the driver if the hand brake and hand brake are not applied when the driver leaves the driver's seat after the engine is stopped and a control device are connected to a power source so that they can operate even after the engine is stopped, and are set to automatically turn off when a hand brake detection signal and hand brake detection signal are input to the control device.

After the engine is stopped, unless the hand brake is applied and the wheels are chocked, the warning activation such as the voice message will continue, so the driver must apply the hand brake and the wheels when leaving the maintenance vehicle after the engine is stopped. When the hand brake is applied and the wheels are chocked, the power to the device is automatically turned off, so there is no need to forget to turn it off, which is convenient.

However, the technology described in Patent Document 1 is configured such that a detection unit attached to the hand brake detects that the hand brake has been placed between the wheel tread of the vehicle and the rail, and transmits this information wirelessly to on-board equipment. This requires that a power source such as a battery be installed inside the hand brake, which is inconvenient as it requires management of the hand brake's power supply. In addition, because communication is performed wirelessly, there is the inconvenience that operation becomes unstable due to the influence of noise inside and outside the maintenance vehicle. In particular, some maintenance vehicles use diesel engines as their power source, which generate a large amount of radio noise.

In addition, the technology described in Patent Document 2 has a hand stopper detection means such as a magnetic sensor in the hand stopper. Therefore, as in the case of Patent Document 1, there is the inconvenience of needing to manage the power supply for the hand stopper.

The following describes in detail an embodiment of the present invention with reference to the drawings.

First Embodiment
A first embodiment of the present invention will be described with reference to FIGS.
First, with reference to Figs. 1 to 4, a use example, configuration, and operation of a hand-grip monitoring device 1 and a hand-grip detector 2 used therein will be described.
FIG. 1 is a perspective view showing an example of use of the hand-grip monitor 1, FIG. 2 is a perspective view showing the configuration thereof, FIG. 3 is a block diagram thereof, and FIG.

Figure 1 shows the use of the hand stop 100, with the hand stop 100 installed between the tread of the wheels 210 of the maintenance vehicle 200 and the rails 310 of the track 300. The hand stop detector 2 of the hand stop monitoring device 1 is attached and fixed facing downward to a stay 230 protruding downward from the underside of the body 220 of the maintenance vehicle 200. Details of the method of fixing the hand stop detector 22 will be described later.

As shown in FIG. 1, the hand pawl 100 is the same as that which has been conventionally used, and is also called a scotch or hand scotch. The hand pawl 100 is configured as a pair of two pieces, and has a hand pawl body 110 formed in an approximately wedge shape, and a rod-shaped grip bar portion 120 that protrudes laterally from the hand pawl body 110 and extends approximately horizontally in a direction approximately perpendicular to the rail 310. A connecting cord 140 is fixed to the end of the grip bar portion 120, connecting the pair of hand pawls 100 to each other.

As shown in FIG. 1, reflective tape 130 is attached to the grip bar portion 120 so that it is visible even at night when maintenance work is performed. The hand stopper body 110 is made of resin and has a rectangular parallelepiped shape with a mountain-shaped upper surface and two roughly wedge-shaped slopes. The hand stopper body 110 is configured so that even if the wheel 210 runs over it, it will not disintegrate or the upper part will not become concave, causing the maintenance vehicle 200 to derail.

2, the hand latch monitor 1 has a hand latch detector 2, a monitor body 3, and a retraction detector 4. The hand latch detector 2 and the retraction detector 4 are connected to the monitor body 3 by connecting cables 5, 5, respectively, and a waterproof connector 51 is provided between the connecting cable 5 between the hand latch detector 2 and the monitor body 3.

The configuration of the manual brake monitoring device 1 will be described with reference to FIG. 2 and the block diagram shown in FIG.
As shown in FIG. 2, the hand latch detector 2 has a waterproof hand latch detector case 21 formed in a substantially rectangular shape, and has three holes 22, 22, 22 on its end faces which are watertightly sealed with transparent resin or the like.

As shown in Figure 3, inside these three holes 22, 22, 22, there is provided a laser pointer 22 (laser point irradiation means), a distance measuring sensor 23 (optical distance measuring section), and a display LED 24, each of which is connected to a control section 26 via interfaces 25, 25, 25. A memory 27 is connected to the control section 26, and it is also configured to communicate with the monitoring device main body 3 via a communication section 28. The distance measuring sensor 23 is of the TOF (time of flight) type that uses an ultra-small laser beam.

As shown in Figures 2 and 3, the storage detector 4 has a hook-shaped storage detector body 41, and a microswitch is attached to the bottom of the hook to form a storage detector 42. The storage detector 4 is fixed to the wall inside the maintenance vehicle 200, and when the handrail 100 is removed from between the wheel 210 and the rail 310 and hung from the storage detector 4 by the connecting cord 140, the storage detector 42 is activated.

As shown in FIG. 2, the monitoring device main body 3 has a monitoring device main body case 31 configured in a substantially rectangular shape, and on the front is a speaker which is an audio drive unit 32 (attention unit) and four LED lamps 33, 33, 33, 33 (attention units). In addition, a push button for a laser pointer operation unit 34 is provided on the side. The LED lamps 33, 33, 33, 33 respectively display "normal" in blue, "warning" in red, "hand brake installed" in green, and "hand brake not stored" in orange, and are configured to provide warnings and other guidance together with the voice from the speaker 32, as described below.

As shown in FIG. 3, the audio driver 32, LED lamps 33, 33, 33, 33, and laser pointer operation unit 34 of the monitoring device main body 3 are each connected to a control unit 36 via an interface 35. A memory 37 and a power supply unit 38 are connected to the control unit 36, and the control unit 36 is configured to communicate with the handgrip detector 2 via a communication unit 39 and with the storage detector 42 via the interface 35.

The function of each part of the manual latch monitor 1 will be described with reference to FIGS.
1 and 3, when the hand latch detector 2 is in operation, the display LED 24 lights up and the distance measuring sensor 23 measures the distance from the hand latch detector 2 to the grip bar portion 120. By operating the push button of the laser pointer operation unit 34, the laser pointer 22 irradiates a laser point in the direction measured by the distance measuring sensor 23 for a predetermined period of time, three minutes in this case. This is to make it possible to confirm the direction measured by the distance measuring sensor 23 by the laser point.

In FIG. 3, the distance measured by the distance sensor 23 is calculated by the control unit 26, and this distance data is sent to the monitoring device main body 3 via the communication unit 28. As described below, the distance range when the hand latch 100 is present is set in advance, and data for this distance range is recorded in the memory 27. When the hand latch detector 2 and the monitoring device main body 3 are first connected and communicate, the data for the distance range in the memory 27 is sent to the monitoring device main body 3 and is configured to be recorded in the memory 37.

In FIG. 3, when the monitoring device main body 3 is powered on by the power supply unit 38, the control unit 36 communicates with the handgrip detector 2 and compares the measured distance data with the distance range data. It then determines whether the handgrip 100 is installed in a specified position between the wheel 210 and the rail 310. Similarly, the storage detector 42 determines whether the handgrip 100 is hung from the storage detector 4 by the connecting string 140 and stored in a specified location. Then, based on the results of these determinations, the control unit 36 activates the audio driver 32 and LED lamp 33 to provide guidance such as a warning.

Now, with reference to the flow chart of FIG. 4, the operation of the manual brake monitor 1 will be described.
As shown in Fig. 4, turning on the power means that the maintenance vehicle 200, which has been parked up until now, is moved. First, in S401, a determination is made as to whether the hand brake 100 is installed in a predetermined position between the wheels 210 and the rails 310. If the hand brake 100 is installed in the predetermined position, the process proceeds to S402, where a voice message and a warning lamp are issued stating "Hand brake installed," and this process is repeated until the hand brake 100 is removed.

In S401 of FIG. 4, if the hand latch 100 has been removed, the process proceeds to S403, where it is hung from the storage detector 4 by the connecting string 140, and a determination is made as to whether the hand latch 100 is stored in the designated location. If the hand latch 100 is not stored in the designated location, the process proceeds to S404, where a voice and warning lamp announce that "the hand latch is not stored," and this process is repeated until the hand latch 100 is stored.

In S403 of FIG. 4, when the hand brake 100 is stored in the designated location, the process proceeds to S405, where a voice and lamp announce that "The hand brake is stored." In other words, in this state, the hand brake 100 is removed so it will not be run over by the wheels, and since it is stored, it will not be left behind. Then, after the hand brake 100 has been confirmed in this way, operation of the maintenance vehicle 200 begins.

After the maintenance vehicle 200 starts to operate, in S406 of FIG. 4, the process continues to check whether the hand stopper 100 is stored in the designated location. When the maintenance vehicle 200 stops operating and the hand stopper 100 is removed from the designated location, the process proceeds to S407. Note that the process is configured to proceed to S407 a predetermined time, in this case 3 seconds, after the hand stopper 100 is removed. This is to prevent the hand stopper 100 from being detected as having been removed when the connecting cord 140 momentarily loosens due to vibrations or the like while the maintenance vehicle 200 is in operation.

In S407 of FIG. 4, if the hand stopper 100 has been removed from the designated location but has not been installed in the specified position between the wheel 210 and the rail 310, the process proceeds to S408. Then, a voice message and warning lamp will be issued stating that "hand stopper has not been installed," and this process will be repeated until the hand stopper 100 is installed.

In S407 of FIG. 4, when the hand brake 100 is installed at the specified position between the wheel 210 and the rail 310, the process proceeds to S409, where a voice and lamp announce that "the hand brake has been installed." In this state, the hand brake is installed on the maintenance vehicle 200 and the vehicle is parked safely, so the power to the maintenance vehicle 200 is turned off.

Next, how the distance range for detecting the hand restraint 100 is set will be described with reference to FIGS. 5 and 6. FIG.
The setting is performed using the manual latch detector setting device 6. Fig. 5 is a perspective view showing the configuration when performing the setting, and Fig. 6 is a block diagram thereof.

As shown in FIG. 5, the hand stop detector setting device 6 has a hand stop detector setting device case 61 formed in a substantially rectangular shape, and is provided with a display unit 62 consisting of a liquid crystal display, and an operation unit 63 consisting of a cross key.
6, the display unit 62 and the operation unit 63 of the hand stop detector setting device 6 are each connected to a control unit 65 via an interface 64. A memory 66 is connected to the control unit 65, and the control unit 65 is configured to communicate with the hand stop detector 2 via a communication unit 67.

As shown in FIGS. 5 and 6, the setting of the manual latch detector 2 is performed by connecting a manual latch detector setting device 6 via a connecting cable 5.
When the hand stop detector setting device 6 is connected, power is supplied to the hand stop detector 2 and the laser pointer 22 is configured to emit light while the detector is connected. This is to allow the hand stop detector 2 to be attached and set simply by connecting the hand stop detector setting device 6. In other words, to achieve the state shown in Fig. 1, the hand stop detector 2 can be attached to the stay 230 while watching the position of the laser point, and then immediately set.

Next, a method of setting the manual latch detector setting device 6 will be described with reference to FIGS.
5, the distance to the hand latch 100 is displayed as "Dist" on the display unit 62, and the operation unit 63 is operated to move the display down one level and then set the longest distance as "Max," and similarly set the shortest distance as "Min." After setting the distance range in this way, by moving to "SET" and pressing down the cross key of the operation unit 63, the setting is confirmed and the data on the distance range is recorded in the memory 27 of the hand latch detector 2.

In this way, the range of distances from the hand stop detector 2 when the hand stop 100 is present is set. The reason for setting the maximum distance here is to prevent malfunction when the sleepers 320 and gravel (ballast) 330 under the rail 310 as shown in Figure 1 are recognized. Similarly, the reason for setting the minimum distance is to prevent malfunction when an unrelated obstruction, such as the leaves of a nearby plant, gets in the way.

Here, as mentioned above, the distance width data recorded in the memory 27 of the hand stop detector 2 is sent to the monitoring device main body 3 when the hand stop detector 2 and the monitoring device main body 3 are first connected and communicate with each other, and is used to detect the hand stop 100.
1, it is preferable to attach reflective tape 130 to the point of the hand pawl 100 where the distance is measured. Although distance measurement is possible without the reflective tape 130, this is because more stable distance measurement is possible even under strong direct sunlight, for example.

As described above, in this embodiment, a conventional hand stop can be used as is, and a stable operation can be obtained. In other words, since the hand stop is optically detected, a conventional hand stop can be used as is, and there is no need to manage the power supply of the hand stop. In addition, each device is connected by wire, and there is no instability in operation as occurs when communication is performed wirelessly. Furthermore, in this embodiment, the method of detecting the hand stop is realized by a simple method of distance measurement, which makes it extremely reliable.

In the present embodiment, the optical distance measurement unit has been described as using a TOF (time of flight) distance measurement sensor 23 that uses laser light, but this is not limiting. It may be a phase difference detection type or a triangulation type. Also, it may be a type that uses near infrared rays instead of laser light.

In addition, although the laser pointer 22 has been used as the laser point irradiation means in this embodiment, this is not limited to this. For example, if a device that uses a semiconductor laser of visible light for distance measurement is used, the irradiation point can be confirmed with the naked eye, so that distance measurement and laser point irradiation can be used together.

In addition, in this embodiment, the monitoring device main body 3 is configured to make a decision about installation based on information about the distance from the handgrip detector 2 and to provide guidance such as a warning, but this is not limited to this. For example, the handgrip detector 2 may be configured to make a decision about installation and have the monitoring device main body 3 provide guidance such as a warning. In this embodiment, the reason that the monitoring device main body 3 is configured to concentrate on making decisions, etc., is that the monitoring device main body 3 is installed inside the vehicle and is not waterproof, making it easy to handle and easy to update firmware, etc.

In addition, in this embodiment, the hand stop detector 2 is set by the hand stop detector setting device 6, but this is not limited to this. For example, the monitoring device main body 3 and the hand stop detector setting device 6 may be configured as one unit to set the hand stop detector 2. In this embodiment, the hand stop detector setting device 6 is separate from the monitoring device main body 3 because the hand stop detector 2 only needs to be set the first time, and functions that are not normally used are removed from the hand stop detector 2 to simplify the process.

In addition, in this embodiment, one hand stop detector 2 is attached to one monitoring device main body 3, but this is not limited to the configuration. For example, two hand stop detectors 2 may be attached to one monitoring device main body 3. If two hand stop detectors 2 are attached, a warning will be issued if both of the pair of hand stoppers 100, 100 are not installed in the specified position, thereby further increasing safety.

In addition, the hand stop detector 2 in this embodiment is fixed to the stay 230 on the underside of the vehicle body 220, but is not limited to this. It may also be fixed to a fixed part of the vehicle body 220 that can detect the hand stop 100 using metal fittings or the like. The hand stop detector 2 is installed on the underside of the vehicle body 220 to reduce the risk of the hand stop detector 2 becoming dirty due to rain or other factors, which could block the light path of the distance sensor 23.

Furthermore, the storage detector 4 of this embodiment can also be expressed as follows.
A storage detection device for detecting whether a hand latch is stored in a designated place inside a vehicle, the hand latch being configured as a pair of two, with a hand latch body formed in an approximately wedge shape, a rod-shaped grip bar portion protruding laterally from the hand latch body, and a connecting cord connecting the pair of hand latches to each other, the storage detection device having a hook-shaped storage detection device body and a storage detection portion which operates when the connecting cord is hung, and configured to detect the storage of the hand latch when it is hung.
By configuring the storage detector 4 in this manner, it is possible to firmly hold the stored hand pawl 100 and perform stable detection.

Furthermore, the manual brake monitoring device 1 of this embodiment can also be expressed as follows.
This hand-clasp monitoring device is configured so that the distance in the direction of a hand-clasp installed at a specified position between the rail and the wheel is optically measured by a hand-clasp detector fixed to the vehicle body, and whether or not the hand-clasp is installed at the specified position is determined based on whether or not the measured distance is within a predetermined range, and a warning or other guidance is given.
By configuring the hand stop monitoring device in this manner, it is possible to use a conventional hand stop as is, and the hand stop detection operation can be performed stably.

Second Embodiment
A second embodiment of the present invention will now be described with reference to FIG.
In the second embodiment, like the first embodiment, the hand stop monitoring device 1 has a hand stop detector 2, a monitoring device main body 3, and a retraction detector 4, but the configuration of the retraction detector 4 is different.
In the following, the same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted, and only the different parts will be described.

As shown in FIG. 7, the storage detector 4 of this embodiment has a storage detector 42 with a protruding operation part like a push button switch in the center of the storage detector main body 41, and above and below it are gripping parts 43, 43 for gripping the grip bar 120. In other words, when the grip bar 120 of the hand pawl 100 is clamped and held between the gripping parts 43, 43, the storage detector 42 is activated and the information is transmitted to the monitoring device main body 3 via the connecting cable 5. Note that two storage detectors 4 may be installed to correspond to a pair of hand pawl stops 100, and each may be configured to be connected to the monitoring device main body 3.

As shown in FIG. 7, the hand restraint 100 is firmly fixed to the storage detector 4 by the gripping parts 43, 43, and because it is hook-shaped and hung by the connecting cord 140 as in the first embodiment, the hand restraint 100 does not swing while driving. Therefore, this embodiment is used when attaching the storage detector 4 to the wall inside the vehicle near the driver's seat.

Here, the hand pawl body 110 of the hand pawl 100 of the first embodiment has two approximately wedge-shaped slopes and is made of resin, but in this embodiment, a different structure that has been used previously is used. That is, as shown in FIG. 7, the hand pawl body 110 has only one approximately wedge-shaped slope and is made of wood, and the grip bar portion 120 is made of PVC pipe (rigid polyvinyl chloride pipe). If the hand pawl 100 has only one approximately wedge-shaped slope, there is a direction when it is attached under the wheel 210. Furthermore, if it is made of wood, if the wheel 210 accidentally goes over the hand pawl 100, it may crack and break or run off the wheel.

In this embodiment, a wooden hand stopper 100 as shown in FIG. 7 is used, but this is not limiting. A resin hand stopper 100 as in the first embodiment can also be used, and any other configuration may be used as long as it is provided between the wheel 210 and the rail 310. For example, a hand stopper made of metal such as iron may also be used. Note that a metal hand stopper is strong and has excellent anti-rolling properties, but if the vehicle is started without being removed, the hand stopper 100 will not break, and there is a risk of the wheel coming off.

Furthermore, the storage detector 4 of this embodiment can also be expressed as follows.
This is a storage detection device which detects whether a hand latch is stored in a designated place inside a vehicle, the hand latch having a roughly wedge-shaped hand latch main body and a rod-shaped grip bar portion protruding laterally from the hand latch main body, and the storage detection device 4 has a storage detection portion in the center of the storage detection device main body from which an operating portion such as a push button switch protrudes, and above and below it are gripping portions for gripping the grip bar portion, and the storage detection device is configured so that when the grip bar portion of the hand latch is clamped and held in the gripping portions, the storage detection portion is activated, thereby detecting the storage of the hand latch.
By configuring the storage detector in this manner, it is possible to firmly hold the stored hand pawl and perform stable detection.

The hand stop detector of the present invention, and the hand stop monitoring device and hand stop detector setting device using the same are not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the spirit and scope of the present invention.
For example, in the above embodiment, the optical means for detecting the handgrip is optical distance measurement, but the present invention is not limited to this. For example, it is of course possible to use a camera such as a near-infrared camera.

In other words, by mounting a camera on the handgrip detector, it is possible to use image recognition to identify whether the handgrip is installed in the specified position and provide guidance such as a warning. In this case, the configuration is significantly more complicated than a method using optical distance measurement, but it is possible to implement. It is preferable to mount not only a camera but also an infrared illuminator or the like on the handgrip detector. By irradiating the imaging range with infrared rays or the like using an infrared illuminator, the camera can capture a clear image even in the dark.

For example, in the above embodiment, the present invention is described as being applied to a maintenance car, but it is not limited to this. It is of course possible to apply the present invention to general railway vehicles.
