Description

  The present invention relates to a passenger room lighting device that is mounted on a vehicle and illuminates the passenger compartment of the vehicle, and particularly relates to a vehicle that is optimally mounted on a railway vehicle.

  Conventionally, various types of lighting devices are provided in passenger cabins such as railway vehicles and airplanes. Particularly recently, LED lamps have been used as light sources in place of conventional fluorescent lamps (for example, Patent Document 1). In this way, in the case of an illuminating device using an LED lamp as a light source, as described in Patent Document 1, dimming (illuminance) control can be performed relatively easily as compared with a fluorescent lamp.

  Moreover, although it is not a vehicle illumination device, the illumination device which changes color temperature as well as light control is also known as an illumination device using an LED lamp as a light source (for example, Patent Documents 2 and 3). In the illumination device described in Patent Document 2, the color temperature of the entire light color of the light source is changed with time, and the illumination device described in Patent Document 3 changes the color temperature and illuminance so as to reproduce the outdoor environment. It was something to be made.

  The determination unit 23 inputs setting information of various toning patterns and position information (point information) during traveling from the setting information storage unit 22 and inputs information from the toning pattern setting unit 24 described below. Then, various determinations are performed based on these information, and the determination results are output to the toning data generation unit 25 described later, or the toning information currently on in the lighting unit 11 is determined and output to the outside. To do.

  Such a determination unit 23 constitutes “monitoring means” for detecting various types of information. In particular, the position information is received, for example, from a speed generator (not shown) provided in the railway vehicle 1 as a wheel rotation speed (a pulse signal corresponding to the wheel rotational speed), and based on this, the current traveling position of the railway vehicle 1 is determined. It may be calculated or using a general GPS function.

  The toning pattern setting unit 24 is a lighting unit identification ID information ROM 27 that stores identification IDs for identifying individual lighting units 11 and a lighting unit that stores other identification IDs for identifying the lighting units 11 for each vehicle (car). In addition to inputting the identification ID information ROM 28 and the toning pattern storage unit 29 storing a plurality of toning patterns corresponding to various types of information determined (detected) by the determination unit 23 (monitoring means), the crew member operation Is also input, and a predetermined toning pattern is set based on the information.

Information based on an operation when a color pattern is selected is also included.

  The toning data generation unit 25 generates predetermined toning data for actually toning the lighting unit 11 based on the information output from the determination unit 23 and the toning pattern setting unit 24. . Based on the toning data, a toning pattern is generated by the toning control unit 14 of the lighting unit 11 described later. The toning data generated by the toning data generation unit 25 is output from the modulation / transmission unit 21A of the transmission / reception unit 21 to the illumination unit 11 as a control signal.

  In the example shown in FIG. 1, only one control means 20 is provided in the crew room of the leading vehicle 1A. However, as shown in FIG. 5, not only the leading vehicle 1A but also the last vehicle, for example. 1N may also be provided. In this case, the control means 20 of the leading vehicle 1A is normally operated. However, it is preferable to set the control means 20 in the vehicle 1N to be operated when some trouble occurs in the control means 20.

  FIG. 6 is a block diagram showing details of the illuminating means 11 for unidirectional communication, and FIG. 7 is a block diagram showing details of the illuminating means 11 for bidirectional communication. 6A is a block diagram when the identification ID for each illumination unit 11 is not used, and FIG. 6B is a block diagram when the identification ID is used. First, as shown in FIG. 6A, the transmission / reception unit 13 (see FIG. 2) of the illuminating unit 11 is for unidirectional communication. Therefore, the reception / demodulation unit demodulates the control information input from the control unit 20. 131, and a reception determination unit 133 that determines reception of the demodulated control signal and other signals and transmits the received signal to the toning control unit 14.

  The toning control unit 14 is provided for each light source 12 and a toning pattern generation unit 141 that generates a toning pattern based on the toning data received via the reception determination unit 133. The light control unit 142 directly controls driving based on the toning pattern from the toning pattern generation unit 141. In the example illustrated in FIG. 6, the individual light sources 12 are dimmed by the dimming control unit 142, thereby adjusting the ratio of the light emission levels of the respective light sources 12 so that the lighting can be performed at the color temperature of the intended toning pattern. Has been. Strictly speaking, the toning control unit 14 also corresponds to the “control unit” that adjusts the illumination of the illumination unit 11 (light source 12) together with the control unit 20.

  Further, the block diagram of the illumination means 11 shown in FIG. 6B is the same as the block diagram shown in FIG. 6A described above except that the identification ID setting unit 15 is connected to the reception determination unit 133. is there. Here, the identification ID setting unit 15 is a switch for selecting a toning pattern of the illumination means 11 for each individual illumination means 11 or for each vehicle (car) by an operator (crew) manually. The identification ID for identifying the means 11 is obtained from the illumination means identification ID information ROMs 27 and 28 described above. The identification ID setting unit 15 may be provided not in the illumination unit 11 but in the control unit 20 in the crew room so that the control unit 20 can perform the operation intensively.

  In the block diagram of the illumination means 11 for two-way communication shown in FIG. 7, only the configuration of the transmission / reception unit 13 (see FIG. 2) is different from the block diagram shown in FIG. That is, in FIG. 7, since the transmission / reception unit 13 (see FIG. 2) is for two-way communication, in addition to the reception / demodulation unit 131 that demodulates the control information input from the control unit 20, information related to lighting of the illumination unit 11 A modulation / transmission unit 132 that modulates and transmits the signal is also provided. The reception determination unit 133 is also provided. Although the identification ID setting unit 15 is provided in FIG. 7, the identification ID setting unit 15 may be omitted.

Next, the operation of the cabin lighting device 10 according to the present embodiment will be described.
According to the passenger room lighting device 10 according to the present embodiment, the illumination means 11 that illuminates the passenger compartment of the railway vehicle 1 includes the light source 12 composed of LED lamps that are easily dimmable, and the light source 12 has different color temperatures. A plurality of light sources 12A and 12B are combined. Therefore, the color can be adjusted to a desired color temperature which is a predetermined color adjustment pattern by various combinations of the light emission levels of the light sources 12A and 12B.

  In the color adjustment of the illumination unit 11, when various types of information are detected by the determination unit 23 of the control unit 20 constituting the monitor unit in FIG. 4, the determination unit 23 displays information on the color adjustment pattern corresponding to the information. Obtained from the pattern setting information ROMs 22a to 22c, the toning pattern storage unit 29, and the like. Here, the determination unit 23 identifies information that corresponds to the current situation from among the various pieces of detected information, and collates the toning pattern that matches this. The toning pattern is transmitted from the control unit 20 to the toning control unit 14 via the transmission / reception unit 13 of the lighting unit 11, and the light source 12 is toned based on the toning pattern under the control of the toning control unit 14. .

  As described above, the cabin lighting device 10 can perform various color adjustments according to various information. The various types of information include point information that changes with the movement of the railway vehicle 1, environment such as whether the point is an urban area or a suburb, external conditions such as weather, and calendar information or time information that specifies the date and time. The classification of various events is possible. Hereinafter, based on a specific example, it demonstrates along the flowchart of FIGS.

FIG. 8 is a flowchart showing the flow of control for color matching according to the travel position.
Initially, the determination part 23 of the control means 20 acquires driving | running | working position information based on point information from wheel rotation speed, GPS, etc. as mentioned above (step S101). Subsequently, the determination unit 23 acquires toning pattern information regarding the travel position (step S102). At this time, the determination unit 23 accesses data such as the position / tone pattern setting information ROM 22c (step S103).

  And the determination part 23 collates driving | running | working position information and the acquired toning pattern (step S104). Next, the light source 12 of the illumination unit 11 is toned based on the toning pattern corresponding to the collation (step S105). Here, as a specific toning pattern, for example, from the first station to the middle station, the color is white or cold, and from the middle station to the end station, the light bulb color or warm color is used. It is conceivable. Thus, the color of the illumination means 11 can be changed according to the traveling position.

FIG. 9 is a flowchart showing the flow of control for color matching according to the current time.
First, the determination unit 23 of the control unit 20 acquires current time information (step S111). Here, the current time information can always be obtained from the internal clock 26 provided in the control means 20 (step S112). Subsequently, the determination unit 23 acquires toning pattern information regarding time (step S113). At this time, the determination unit 23 accesses data such as the time / toning pattern setting information ROM 22a (step S114).

  Then, the determination unit 23 collates the current time information with the acquired toning pattern (step S115). Next, the light source 12 of the illumination unit 11 is toned based on the toning pattern corresponding to the collation (step S116). Here, as a specific toning pattern, for example, it can be considered that the toning is a white or cold color from morning to daytime, and a light bulb or warm toning from evening to night. Thus, the color of the illumination means 11 can be changed according to the time.

FIG. 10 is a flowchart showing a control flow for color matching according to the date.
First, the determination unit 23 of the control unit 20 acquires current date information (step S121). Here, the current date information can also be obtained constantly from the internal clock 26 provided in the control means 20 (step S122). Subsequently, the determination unit 23 acquires toning pattern information related to the date (step S123). At this time, the determination unit 23 accesses data such as the date / toning pattern setting information ROM 22b (step S124).

  Then, the determination unit 23 collates the current date information with the acquired toning pattern (step S125). Next, the light source 12 of the illumination unit 11 is toned based on the toning pattern corresponding to the collation (step S126). Thus, the color of the illumination means 11 can be changed according to the date. In addition, for toning based on the date, a large number of different toning patterns may be prepared every day, but the toning patterns prepared for a predetermined number of days may be repeatedly rotated.

  In addition to the time and date, the lighting unit 11 may be controlled to be toned based on information on the day of the week and season that can be obtained from the internal clock 26 in the same manner. For example, when toning based on the season, in spring, it will be colored warbler, in summer it will be light blue, in autumn to winter it will be warm, or the pattern will be simplified. It is also possible to adjust to neutral white from spring to summer and to light bulb from autumn to winter.

FIG. 11 is a flowchart showing the flow of control for color matching according to the car (vehicle).
Initially, the determination part 23 of the control means 20 acquires identification ID information of all the illumination means 11 (step S131). Here, the identification ID information for each illumination unit 11 is acquired from one illumination unit identification ID information ROM 27 via the toning pattern setting unit 24 (step S132). Subsequently, the determination unit 23 also acquires identification ID information of the illumination unit 11 for each car (vehicle) (step S133). Here, the identification ID information of the illumination means 11 for each car (vehicle) is obtained from the other illumination means identification ID information ROM 28 via the toning pattern setting unit 24 (step S134).

  And the determination part 23 acquires predetermined toning pattern information based on the information etc. which were input by crew member operation by the identification ID setting part 15 grade | etc., (Step S125). At this time, the determination unit 23 accesses data such as the toning pattern storage unit 29 in which a predetermined toning pattern is stored or the toning pattern setting information ROMs 22a to 22c (step S136). Next, predetermined toning data is generated by the toning data generation unit 25 (step S137), and the identification ID already acquired is added to the toning data (step S138), and then the illumination means 11 is applied. Data is transmitted (step S139), and the light source 12 of the illumination means 11 is color-adjusted.

  In this way, the control means 20 can adjust the color of the illumination means 11 individually or in units of cabins. Specifically, for example, only women-only vehicles are toned in a light pink or light bulb, and other vehicles are toned in white, or even in passenger cabins of the same vehicle, silver seats, wheelchair areas, etc. It is conceivable that only the illumination means 11 in a specific area is toned in a light bulb color or warm color, and the illumination means 11 in other areas is toned in a white or cold color system. In this way, by assigning an identification ID that can be identified individually or for each car (vehicle) to the lighting means 11, various tonings can be performed on the lighting means 11 individually or on a car (vehicle) basis. .

  By the way, flag data indicating the priority is added to each toning pattern described above so that the toning data of the higher priority classification is preferentially selected from the flag data. Is set. Specifically, for example, a 2-bit priority flag is assigned to the 6th bit of each header data among the toning pattern data. Here, as an example of 2 bits, “00” is defined as the highest priority, “01” is defined as the high priority, “10” is defined as the medium rank, “11” is defined as the low rank, etc. Keep it.

  And the determination part 23 of the control means 20 can determine a priority by identifying the said 2 bits from each toning pattern data read from each said toning pattern. For example, if the toning pattern related to the time mentioned above has the highest rank and the toning pattern related to other dates, the toning pattern related to the running position, etc. are all lower than the high rank, the lighting means uses the toning pattern related to the time. 11 is toned.

  In addition, since the toning patterns with the same rank priority may overlap, it is preferable to prioritize each toning pattern classification. For example, when priorities overlap, in the above-described example, ranking is performed in advance such that time <date <traveling position. Accordingly, for example, when each toning pattern related to the date and the traveling position is the flag having the same priority, the lighting position is illuminated with the toning pattern related to the traveling position because the traveling position> the ranking of the date. The means 11 is toned.

  Furthermore, as described above, the toning pattern can also be selected by a manual operation (crew operation) by a crew member (operator), but when any toning pattern is selected by the manual operation, Regardless of the priority, it is set so that the toning pattern selected by manual operation is given priority. Thereby, for example, even when the color is adjusted based on the color adjustment pattern related to the traveling position, another color adjustment pattern is selected by the manual operation of the crew, or as described above, for each individual illumination means 11 or the car number. When the toning in units of (vehicles) is selected, the lighting means 11 is toned by switching to these manually selected toning patterns.

  Further, when the control means 20 and the illumination means 11 are configured for the unidirectional communication shown in FIGS. 3 and 6, the illumination means 11 normally outputs a control signal (toning pattern information) from the control means 20. When the lighting means 11 cannot be received, the lighting means 11 is toned based on the toning pattern prepared in advance for communication failure. As a result, even if a communication failure occurs due to a failure or disconnection of the control means 20 itself, a predetermined color matching is possible.

  The emergency toning pattern here may be determined as appropriate. In addition, for example, the determination regarding the communication failure is set so that the control signal is transmitted from the control unit 20 at a predetermined interval, and when the illumination unit 11 on the receiving side has not received more than a predetermined time. It is good to determine that communication is regarded as poor. In such a case, the illumination unit 11 adjusts the color of the light source 12 by its own color adjustment control unit 14.

  When the control unit 20 and the illumination unit 11 are configured for bidirectional communication as shown in FIGS. 4 and 7, the illumination unit 11 also has a bidirectional communication function, and the reception determination of the illumination unit 11 is performed. Information can be transmitted from the unit 133 to the control means 20. As a result, the actual situation in the illumination means 11 can be grasped not only on the control means 20 side but also so-called feedback control can be performed. In addition, you may comprise so that the input / output of the control apparatus in the control means 20 may be divided into two systems.

  Further, as shown in FIG. 5, a plurality of control means 20 may be provided in the same or different vehicles. As described above, when a plurality of the control means 20 are provided, any one of the control means 20 is normally operated to control the color adjustment of the illumination means 11. If it occurs, it is set so that the other control means 20 is operated to control the color adjustment of the illumination means 11. Thereby, even when the control means 20 is broken or disconnected, the toning control based on the original toning pattern can be performed.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to the above-described embodiments, and there are changes and additions within the scope not departing from the gist of the present invention.
