Abstract
Description
[Technical field]
[0001] The present invention relates to a door erroneous operation prevention system that can reliably prevent erroneous manual command to open or close the doors of a traveling vehicle when the train stops at a station or stops in the wrong position. [Background technology]
[0002] When a train stops and the doors are to be opened, opening doors that are not the intended opening doors is extremely dangerous. For example, when a moving train stops, if the door on the opposite side of the platform is opened, passengers may fall off. Therefore, the driver must properly recognize whether the platform at the stop station is on the right or left side of the moving train.
[0003] It is also extremely important for trains to stop properly at designated stopping positions. The designated stopping positions are set taking into consideration not only passenger boarding and alighting, but also the location of elevators and stairs at stations. If the stopping positions are not aligned, there is a risk that trains will run off the platform and stop at stations with short platforms. Furthermore, even within the same station, stopping positions may differ depending on the number and type of trains running.
[0004] As a countermeasure against such a problem, there are conventional mechanisms for informing traveling vehicles of the platform location and appropriate stopping positions. Specifically, there are mechanisms using GPS measuring devices, mechanisms in which detection devices are attached to the platform and the vehicle, and the signals of each are compared to inform that the traveling vehicle is stopped at an appropriate stopping position within the platform (JP Patent Publication 2007-15574). [Prior art documents] [Patent documents]
[0005] [Patent Document 1] JP 2007-15574 A Summary of the Invention [Problem to be solved by the invention]
[0006] However, it is not possible to guarantee that only the platform side door can be opened without malfunction. Ideally, it would be desirable to have a mechanism that could more reliably prevent such malfunctions. In addition, it is not certain that a moving vehicle will stop reliably at the designated stopping position. If the driver opens the door without realizing that the train has stopped at the wrong stopping position and there is no platform, there is a risk that passengers may fall off. This problem can occur even if conventional technology issues an alarm or other warning to inform passengers that the train has stopped at the wrong stopping position.
[0007] In addition, in recent years, trains are frequently split and joined at stations along the way, which can lead to changes in the number of cars connected. This situation makes it more difficult for drivers to keep track of the number of cars running, and there is a risk that this will lead to an increase in mistakes in stopping positions.
[0008] In addition, there are many routes in depopulated areas where only one driver is in charge, and the burden on the driver is increasing. This situation is a factor that leads to driver negligence.
[0009] Furthermore, the device described in Patent Document 1 requires the installation of a device on both the track and the vehicle body, and the device itself is very expensive. In addition, the maintenance costs and device replacement costs are also high, leaving room for improvement from an economic perspective. [Means for solving the problem]
[0010] The present invention aims to solve the following problems: That is, the present invention aims to provide a system for preventing erroneous door opening and closing of a traveling vehicle, in which an operating device cover having an operation locking function is installed on a device that performs door opening and closing operations in a manual door opening and closing operation system for a moving vehicle that stops at a specified stop, and the operating device cover can be operated and locked based on a frequency signal transmitted from a transmitting device provided in the stopping position recognition device of the moving vehicle, and when the moving vehicle is stopped at the specified stopping position, the opening and closing operating device of the door on the opposite side of the moving vehicle from the boarding and alighting platform is locked, thereby making it possible to prevent erroneous operation of the door.
[0011] The present invention is also characterized in that the opening and closing operation of the left and right doors when the vehicle is stopped can be converted to either the left or right door by signals having different frequencies.
[0012] Furthermore, the present invention relates to a door opening / closing system that enables manual door opening and closing operations for a moving vehicle configured to stop at a specified stopping position, and is characterized in that an operating device cover is provided on the operating device that performs the door opening and closing operation as an operation locking function, and when the vehicle stops away from the specified stopping position, the operating device cover is configured to lock the cover based on a frequency signal from a transmitting device provided in the stopping position recognition device. Effect of the Invention
[0013] According to the present invention, when a traveling vehicle enters the platform, a frequency signal is sent from a transmitter installed in the stop position recognition device to lock the door opening / closing device cover located above either the left or right door opening / closing operation switch, thereby reliably preventing the incorrect opening of doors on sides other than the platform.
[0014] Furthermore, if a train is not stopped at the proper designated stopping position, an alarm is sounded to inform the driver of the incorrect stopping position, and the door opening / closing switch cover is locked to disable the door opening / closing switch itself. With this system, even if a train is stopped at the wrong position, the door opening / closing operation itself can be disabled, and the risk of the door opening at a position other than the correct stopping position can be reliably eliminated. In addition, by changing the stopping position detection device to an inexpensive electronic device such as an iPad (registered trademark), a stopping position confirmation device and malfunction prevention device are provided that are extremely inexpensive compared to conventional position detection devices using RFID tags, etc. [Brief description of the drawings]

[0016] The present invention is a manual door opening / closing operation system for a moving vehicle that stops at a specified stop, in which an operating device cover with an operation locking function is installed on a device that performs door opening / closing operations, and the operating device cover can be operated and locked based on a frequency signal transmitted from a transmitting device provided in the moving vehicle's stopping position recognition device, and when the moving vehicle is stopped at a specified stopping position, the opening / closing operating device of the door on the opposite side of the moving vehicle from the boarding / disembarking platform is locked, thereby preventing erroneous operation of the door.
[0017] <1. Devices Constituting the System of the Present Invention> First, the system of the present invention will be described with reference to Figures 1 and 2. Figure 2 shows the system during one-man operation. A stop position recognition device 1 is provided near the driver's seat, and the position of the moving vehicle is measured at any time using the GPS (Global Positioning System) function of the stop position recognition device 1. The stop position recognition device 1 is, for example, an iPad (Apple Inc.). The electronic terminal that functions as the stop position recognition device 1 is always connected to a charging device and is turned on while the vehicle is moving.
[0018] As an embodiment of the present invention, the stop position recognition device 1 is an iPad or the like, and is connected to an external device through an earphone jack 1a of the stop position recognition device via an electrical wiring such as an audio input / output cable. The inner diameter of the earphone jack is, for example, φ3.5 mm. The audio input / output cable connected to the earphone jack of the stop position recognition device 1 branches into two cables along the way. One of these cables is hereinafter referred to as the R side, and the other as the L side. The R side cable and the L side cable are connected to different devices at the end. The R side cable is connected to an isolator 5 at the end for the purpose of removing ground loop noise, and the isolator 5 is connected to a control amplifier 6 via an electrical wiring such as a 600V vinyl insulated electric cable. The control amplifier 6 is connected to a passenger compartment speaker 7 via an electrical wiring such as a 600V vinyl insulated electric cable.
[0019] On the other hand, the L-side cable is connected to a magnet drive box at the end thereof in order to select a specific frequency component from the transmitted electronic signal. The transmitted electronic signal is, for example, an analog signal. An analog filter 2 built into the magnet drive box selects the transmitted electronic signal into a low-frequency electronic signal in a frequency band of about 0 to 4 kHz and a high-frequency electronic signal in a frequency band of about 19 kHz. Of these, the low-frequency electronic signal in the frequency band of about 0 to 4 kHz is transmitted from the analog filter 2 to the cab speaker 3 connected via electronic wiring such as a 600V vinyl insulated electric cable, and is output from the cab speaker 3 as a warning sound for the driver. On the other hand, the high-frequency electronic signal with a frequency of about 19 kHz is connected to an armature plate of a locking unit 8 for locking the cover, which is disposed on the door opening / closing operation switch cover 12, via electronic wiring such as a 600V vinyl insulated electric cable. The emitted high-frequency electronic signal of about 19 kHz is transmitted to the electromagnetic magnet as a control audio signal for the door locking mechanism.
[0020] The door opening / closing operation switch 9 is a rotary switch with a diameter of about 5 cm, which is arranged in two positions, one above the other, with an interval of about 10 cm, near the driver's cab. The upper switch opens and closes the door of the front vehicle among the traveling vehicles, and the lower switch opens and closes the door of the rear vehicle among the traveling vehicles. Each rotary switch can be turned to the left to open the door, and to the right to close the door. Two types of switch boxes of such rotary switch sets are arranged per vehicle: a left door opening / closing switch box 10 and a right door opening / closing switch box 11.
[0021] A door opening / closing operation switch cover 12 is disposed so as to cover the left door opening / closing switch box 10 and the right door opening / closing switch box 11. The door opening / closing operation switch cover 12 is a rectangular transparent cover, and is disposed with dimensions of approximately 20 cm in length, approximately 7 cm in width, and approximately 5 cm in depth. The material of the door opening / closing operation switch cover 12 is, for example, acrylic.
[0022] Approximately 3 cm diagonally to the upper right of the upper rotary switch, a locking portion 8 armature plate for locking the switch cover is disposed as a portion responsible for the locking function of the door opening / closing operation switch cover 12.
[0023] Next, the filters used in the present invention will be described. There are two voice filters used in the present invention: a low-pass filter for voice extraction and a band-pass filter for door-opening direction selection. Of these, the low-pass filter for voice extraction outputs only electronic signals with frequencies in the range of 0 kHz to about 5 kHz. The band-pass filter for door-opening direction selection is a filter that outputs only electronic signals with frequencies in the range of about 16 kHz to about 20 kHz.
[0024] Of these, the low-pass filter for voice extraction is used for warning voices or automatic announcements / advertisements issued from the cab speaker 3. The band-pass filter for selecting door-opening direction is used to select high-frequency electronic signals transmitted to the locking unit 8 of the door opening / closing switch cover and to select whether the left or right door is to be locked. More specifically, the selected 19.0 kHz electronic signal has the function of instructing to lock both doors, the 19.2 kHz electronic signal has the function of instructing to lock the right door, and the 19.4 kHz electronic signal has the function of instructing to lock the left door, and each is transmitted as an electronic signal to the locking unit 8 of the locking unit. The file format of these electronic signals is, for example, WAV format.
[0025] Next, another embodiment of the present invention will be described with reference to Fig. 3. In this embodiment, a system is provided in which a magnet drive box is connected to a camera recorder of a moving vehicle via a wiring cable or the like. The camera recorder is connected to a driver's seat monitor 21 via a DC 100V cable or the like.
[0026] In addition, the frequency bands of the electronic signals used in the door locking system during one-man operation include the aforementioned 19.0 kHz (both door lock instruction function), 19.2 kHz (right door lock instruction function), and 19.4 kHz (left door lock instruction function), as well as a 19.6 kHz electronic signal that has the function of indicating the right side platform display and a 19.8 kHz electronic signal that has the function of indicating the left side platform display, as signals for displaying camera-recorded images on the driver's seat monitor 21.
[0027] Next, the detailed structure of the locking unit in the system of the present invention will be described with reference to Fig. 4. Fig. 4 shows the door opening / closing operation switch cover 12 at the top and the driver's cab panel 35 at the bottom. A cross section of the locking unit 8 is shown in a state in which the driver's cab panel 35 is placed on the bottom and the locking unit is laid down. In this cross section, an armature plate 31 is embedded in the upper door opening / closing operation switch cover 12, and an electromagnet 32 is disposed in an electromagnet holder so as to contact the armature plate 31. When an electronic signal is transmitted from a wiring cable 36, the electromagnet 32 becomes magnetized, and the armature plate 31 and the electromagnet 32 are coupled by magnetic force to be locked, and the driver's door opening / closing operation can be prevented at the locking portion. The electromagnet 32 is connected at its bottom to the driver's cab panel 35 via an iron plate 33 and a non-magnetic material 34.
[0028] <2. Operation mechanism of this device during normal stopping> Next, the operating mechanism of this device, which determines the platform side and locks the door on the opposite side of the platform when a moving vehicle enters a station, will be described with reference to Fig. 2. As mentioned above, a stop position recognition device 1 is installed near the driver's seat, and the position of the moving vehicle is measured at any time using the GPS function of the stop position recognition device 1. In addition, the specified stop position information for each station is input in advance into such electronic device, and the stop number at the stop station and the platform side information at the time of stopping are input. The system into which this information is input is, for example, a driver support app "Notify-kun" downloaded to the iPad or the like that is the stop position recognition device 1.
[0029] In one aspect of such a system, the app can measure the position of a moving vehicle at any time, and stop track number information and platform position information are input in advance. When a moving vehicle approaches a stop station, a high-frequency electronic signal is emitted from the stop position recognition device 1 (step S11). This high-frequency electronic signal is transmitted to the R side and the L side via a cable or the like connected to the stop position recognition device 1 (step S11). Of these, the electronic signal transmitted to the R side (step S13) has ground loop noise removed by the isolator 5, and is amplified by the control amplifier 6 to which it is transmitted via a cable or the like (step S16). The signal is then taken into a broadcast circuit from the control amplifier 6 via a cable or the like (step S17), and is broadcast from the passenger compartment speaker 7 installed in each car.
[0030] On the other hand, the electronic signal transmitted to the L side (step S12) is further frequency-selected by the analog filter 2 via a cable or the like. Here, the selected low-frequency electronic signal with a frequency of 0 to 4 kHz is output as an attention-calling sound from the cab speaker 3. In this case, the attention-calling sound is, for example, "Beep, XX side door opening and closing, XX side door opening and closing, be careful of the door opening side!", etc. Furthermore, the high-frequency electronic signal in the frequency band of about 19 kHz is output via the respective wiring cables as a signal to lock the left and right door opening and closing operation switch covers 12 (steps S18 and S19).
[0031] Then, an electronic signal is transmitted to the armature plate 31 of the locking portion 8 of the door opening / closing operation switch cover 12, and a current flows through the electromagnet, which becomes an electromagnet and locks the door cover. At this time, if the platform is on the right side of the traveling vehicle, only the left door opening / closing operation switch cover is locked (step S18), and if the platform is on the left side of the traveling vehicle, only the right door opening / closing operation switch cover is locked (step S19).
[0032] Here, in steps S18 and S19, the frequency of the high frequency electronic signal is made different so that different instructions are given for locking the left door opening / closing operation switch cover and the right door opening / closing operation switch cover. As a specific example, as described above, a high frequency electronic signal with a frequency of 19.2 kHz is used to lock the right door operation switch cover, and a high frequency electronic signal with a frequency of 19.4 kHz is used to lock the left door operation switch cover. Also, a high frequency electronic signal with a frequency of 19 kHz is used to lock both covers.
[0033] The force of the electromagnetic magnet is approximately 5 kgf. Therefore, the door opening / closing operation switch cover 12 cannot be opened because it is locked. This mechanism reliably prevents the door opening / closing operation switch on the opposite side of the platform from being operated when a traveling train stops at a station.
[0034] <3. Operation mechanism of this device when the stop position is incorrect> This system can also prevent the door from malfunctioning when the stopping position is incorrect. The mechanism by which this device operates when the stopping position is incorrect is described below. As mentioned above, a stopping position recognition device is installed near the driver's seat. This stopping position recognition device measures the position of the running vehicle using GPS functions, etc., and in addition to stopping position information at the stopping stations of the running vehicles, specified stopping position information of the running trains, etc. are also input. Therefore, this stopping position recognition device can also function as a stopping position recognition device. The system into which this stopping position information is input is, as mentioned above, for example, "Tsugaru-kun."
[0035] As one aspect of the stop position measurement of such a system, the application has a platform accommodation detection function and a platform overshoot detection function in addition to measuring the position of the running train. The platform accommodation detection function is a function that notifies the train to stop at an appropriate stop position, and issues an alarm when the train approaches a certain distance before the station and is about to stop at a stop that does not match the number of cars of the running train (an incorrect stop). The judgment of whether or not the train is about to stop at an incorrect stop is made based on the speed of the running train, and it is judged to stop when, for example, the speed drops to 15km / h or less near the stop in question.
[0036] The above stopping system will be described in detail with reference to the flowchart in FIG. 5. First, a traveling train approaches a stop station (step S1). Next, the app judges whether the train is heading for a stop before the specified stop (step S2). At this time, if it is judged that the train is decelerating for a stop before the specified stop (step S2), the platform accommodation detection function is activated and an appropriate stopping position warning is issued (step S7). In this case, the driver recognizes the warning sound and re-accelerates or does not decelerate the traveling train (step S8) and heads for the specified stopping position. Then, when the train passes a specific position near the specified stop, the issuance of the appropriate stopping position warning is stopped (step S9).
[0037] Furthermore, if the train has passed the stop before the specified stop and is heading precisely towards the specified stop (step S3), the app then judges whether or not it is about to pass the end of the platform (step S4). At this time, if it is judged that the train will pass the end of the platform, an overshoot warning is issued (step S10). In such a case, the driver also recognizes the warning and applies stronger brakes and slows down further so as not to pass the end of the platform (step S10). Then, if the train has been able to stop appropriately near the specified stop (step S5), the door opening / closing operation switch cover 12 is not locked and the doors can be opened and closed (step S6).
[0038] Then, together with issuing the appropriate stopping position warning and overshoot warning, the stopping position recognition device 1 issues a high-frequency electronic signal to lock the door opening / closing operation switch cover 12 (steps S7, S10). This high-frequency electronic signal is issued as a sound superimposed on the warning issued by the stopping position recognition device 1. Since this sound is a high-frequency sound that is inaudible to the human ear, even if it is issued from the cab speaker 3 toward the driver, the driver cannot hear it and does not interfere with the warning. Then, while the two types of warnings, the appropriate stopping position warning and the overshoot warning, are being issued, the door opening / closing operation switch cover 12 remains locked.
[0039] Next, the mechanism for locking the doors when a high-frequency electronic signal is emitted from the train stop position recognition device 1 will be described with reference to Fig. 2. The outline is roughly the same as in the case of locking the doors on the opposite side of the platform described above.
[0040] First, when a traveling train makes a mistake in its stopping position, an electronic signal is transmitted to the R side and the L side via a cable or the like connected to this stop position recognition device 1 (step S11). Of these, the electronic signal transmitted to the R side (step S13) is subjected to noise removal by the isolator 5, and the signal is amplified by the control amplifier 6 to which it is transmitted. The signal is then taken into the broadcast circuit by the control amplifier 6 (step S17) and broadcast from the passenger compartment speaker 7 of each car. In this case, the audio broadcast might be, for example, "The stopping position has been incorrect, so the train will move again. Please be careful." This audio is broadcast automatically.
[0041] On the other hand, the electronic signal transmitted to the L side (step S12) is further frequency-selected by analog filter 2 via a cable or the like. Here, the selected low-frequency electronic signal with a frequency of 0 to 4 kHz is output as an attention-calling sound from cab speaker 3. In this case, the attention-calling sound may be, for example, "Beep, here are XX cars. Here are XX cars. Pay attention to the stopping position!". In addition, a high-frequency electronic signal in a frequency band of approximately 19 kHz is output via the respective wiring cables as a signal to lock left and right door opening / closing operation switch covers 12 (steps S18 and S19).
[0042] Then, an electronic signal is transmitted to the armature plate 31 of the locking portion 8 of the door opening / closing operation switch cover 12, and a current flows through the electromagnet, which becomes an electromagnet and locks the door covers. When the stopping position is incorrect, both steps S18 and S19 are activated, and both the left and right door opening / closing operation switch covers 12 are locked. The force exerted by the electromagnet is equivalent to approximately 5 kgf, as described above. Therefore, the locking of the door opening / closing operation switch cover 12 becomes an obstacle, and the driver cannot operate the door opening / closing operation switch, and therefore cannot open the doors at the incorrect stopping position.
[0043] The mechanism for transmitting the electronic signal described above may be of another type. For example, the stop position recognition device 1 outputs an alarm sound and an electronic signal for locking the door opening / closing operation switch cover 12 via a cable. Then, as described above, the signal branches into the R side and the L side, but the L side is directly connected to the driver's speaker at the end and issues an alarm sound together with the electronic signal. On the other hand, the R side is connected to a magnet drive box at the end, and the sound is taken into the magnet drive box. The magnet drive box then uses a built-in analog filter to select detection signals of 10 different frequencies from the electronic signal. Then, it outputs other electronic signals based on those detection signals, and the electromagnetic magnet of the door opening / closing operation switch cover 12 acts via a receiver for the electronic signal, locking the door.
[0044] The means for transmitting the electronic signal from the magnet drive box may be of another type. Specifically, the high-frequency electronic signal may be emitted as a wireless circuit or as a sound from the cab speaker, and may be received by a signal receiving device located near the door opening / closing switch. After the signal receiving device receives the electronic signal, it performs frequency analysis to select the electronic signal and uses the electronic signal in a specific frequency band. A frequency filter may be used for the frequency analysis.
[0045] The locking mechanism for the switch operation cover may be in the following different form. That is, after analyzing the high-frequency electronic signal emitted from the stop position recognition device 1, information is transmitted to a terminal block via a 24V DC or 12V DC cable. Then, the high-frequency electronic signal is transmitted to a solenoid mechanism connected to the terminal block. The solenoid mechanism constitutes a locking section for the operation switch cover of the door opening / closing operation switch, and the operation switch cover is locked by current flowing through the solenoid mechanism. As a result, the driver cannot operate the door opening / closing operation switch.
[0046] In addition, the burden on the driver may be further reduced by adopting a mechanism for projecting the image from the camera on the platform side onto the monitor, which is used in the system for one-man operation. Specifically, as described above, the frequency band used for such electronic signals may be, for example, 19.2 kHz for the signal to lock the door opening / closing operation switch cover 12 of the right door opening / closing switch box 11, and 19.8 kHz for the signal to display the image of the left side of the platform on the monitor. In addition, the timing of issuing the signal to project onto the monitor is, for example, when the traveling vehicle is traveling at a speed of 5 km / h or less. Then, when the traveling train approaches a stop station, the door operation switch cover on the side other than the platform side is locked, and the camera device installed on the platform side of the traveling train projects the platform situation when the traveling train enters the platform onto the driver's monitor.
[0047] Then, after departing from the station and reaching a certain speed, the output of the high frequency signal is stopped and the door opening / closing operation switch cover 12 is unlocked. Then, when the train approaches a station again and decelerates (excluding operational stops), the system built into the stop position recognition device 1 determines the platform position, emits an electronic signal of a specific frequency, locks the door opening / closing operation switch cover 12, and projects an image of the platform on the driver's seat monitor. This cycle is repeated as the train travels.
[0048] <4. Other benefits, etc.> By adopting the system of the present invention, it is possible to prevent doors from being opened due to human error by locking the door operation switch cover for doors that are not on the platform side when a running train enters the platform.
[0049] In addition, by adopting the system of the present invention, when a traveling vehicle stops at an incorrect stopping position, the cover of the vehicle door opening / closing switch can be locked, preventing the driver from touching the opening / closing switch itself, thereby ensuring reliable locking to prevent incorrect opening / closing operations.
[0050] The ability to reliably prevent opening and closing operations eliminates the uncertainty of preventing malfunctions in conventional systems, where the driver must manually decide not to operate the opening and closing switch when a moving vehicle stops in an incorrect stopping position, and makes it possible to reliably prevent malfunctions.
[0051] Furthermore, this feature can more reliably prevent malfunctions when a traveling vehicle stops at an incorrect stopping position than the conventional warning that only uses an alarm sound.
[0052] Furthermore, the system of the present invention can be introduced simply by installing a magnet drive box and a locking unit using an electromagnetic magnet inside the train, and does not require any changes to the interior wiring inside the train. This makes it possible to introduce the system at low cost and with ease.
[0053] In addition, the system of the present invention can be easily expanded in function. In other words, even if the number of vehicles changes in the future or a device that uses vehicle information is added, it is only necessary to connect the additional wiring to the present system. In this respect, it is highly convenient.
[0054] Furthermore, by adopting the system of the present invention, platform detection devices that were previously installed to confirm stopping positions are no longer necessary. Such platform detection devices must be installed on both the moving train and the station platform, and the train-side devices are expensive, and the maintenance costs for the ground-side equipment (replacing the batteries in the ID tags) are also high. Therefore, eliminating the need for platform detection devices leads to significant cost reductions.
[0055] The position detection device and signal transmission device implemented in the system of the present invention is an iPad, and since the frequencies with little sound attenuation in the iPad's sound output are 0kHz to about 20kHz, signals in this frequency band are used. However, as long as it can be detected as an electronic signal, the frequency band to be used is not important.
[0056] In addition, in this embodiment, since it is difficult to use a frequency based on the audio from the R side, only the audio from the L side is used as the frequency, but as long as the frequency transmission device emits audio, the type of device and the type of output are not important.
[0057] In addition, when the driver normally uses the door opening / closing operation switch, the door opening / closing operation switch cover that covers the door opening / closing operation switch is opened when in use.
[0058] The above-described embodiment of the present invention is merely an example. It goes without saying that the manner of use is not important as long as it does not deviate from the scope of the same technical idea. [Explanation of symbols]
