[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0023] Fig. 1 is a diagram showing a schematic diagram of a lighting system 100 according to the present invention. Fig. 2 is a block diagram showing an example of the configuration of a master unit 1. Fig. 3 is a block diagram showing an example of the configuration of a luminaire 2.
[0024] As shown in Fig. 1, the lighting system 100 is provided on a railway vehicle. The railway vehicle 10 has a main unit 1 and a lamp 2. For example, the railway vehicle 10 is a commuter vehicle or an express vehicle capable of running on a track (not shown), and generally has a bogie 11 and a vehicle structure 12 supported by the bogie. The vehicle structure 12 is configured to form a hexahedron by an underframe 13 forming the floor of the railway vehicle 10, a pair of end structures 14 (e.g., gable structures) erected at both ends of the underframe 13 in the track direction to form a coupling portion 5 of the vehicle structure 12, a pair of end sides 15 erected at both ends of the underframe 13 in the sleeper direction to form a side portion of the vehicle structure 12, and a roof structure 16 joined to the upper ends of the pair of end structures 14 and the upper ends of the pair of end sides 15 to form a roof portion of the vehicle structure 12.
[0025] The inside of the car body structure 12 has a passenger compartment and a crew compartment, and the car body structure 12 is provided with a passenger entrance and exit and windows leading to the passenger compartment, and a crew entrance and exit leading to the crew compartment. Handrails (not shown) and the like are fixed to the ceiling of the passenger compartment. In addition to the above, the railway car may have an in-car information screen that displays destinations and news, security cameras, communication devices, and other electronic devices.
[0026] 1, railway vehicle 10 is connected to railway vehicle 20 via a coupling section 5. Railway vehicle 20 has lighting fixtures 22. Similarly, vehicles further connected to railway vehicle 20 via coupling section 5 also have lighting fixtures. That is, signals are transmitted and received by one parent unit and multiple child units.
[0027] The master unit 1 is a wireless terminal that communicates with the slave unit (lamp 2) in a multi-hop manner. In this embodiment, the master unit 1 uses ZigBee (registered trademark), which is a standard of the multi-hop manner. In ZigBee, communication is performed between devices that have a common PAN (Personal area network) ID set.
[0028] For example, when a signal with a specific PANID is sent from parent unit 1, lighting fixture 2 with the same PANID set receives the signal and transmits the received signal as is. When another lighting fixture with the same PANID receives the signal, it transmits the received signal as is. Similarly, signals are sent and received from lighting fixture 2 installed on railcar 10 to lighting fixture 22 on adjacent railcar 20. In this way, signals are sent and received between devices with the same PANID set, and communication is carried out between all devices with the same PANID set.
[0029] The communication method between the parent unit 1 and the luminaire 2 is not limited to ZigBee, and a multi-hop communication other than ZigBee may be used. For example, a communication method may be used in which a wireless node using a specific low-power radio in a predetermined frequency band installed in each device searches for nearby nodes, autonomously constructs a network, and collects data using a bucket brigade. This communication method is characterized by not requiring running costs for communication and being suitable for areas with high residential density. In this embodiment, a monitoring signal S1, which will be described later, is transmitted from the parent unit 1 to the luminaire 2 by broadcast, and the luminaire 2 that receives the monitoring signal S1 forwards the monitoring signal in a bucket brigade manner. Furthermore, the communication method between the parent unit 1 and the luminaire 2 may be a communication method other than multi-hop communication.
[0030] As shown in FIG. 2, the master unit 1 includes a monitor unit 31, a signal generator 32, a presenter 33, and an operation unit .
[0031] The monitoring unit 31 wirelessly outputs a signal (monitoring signal S1) requesting status information, which is information on the status of the luminaire, to one of the luminaires 2, and then wirelessly outputs a monitoring signal to another one of the luminaires 2, for some or all of the multiple luminaires. That is, the monitoring signal S1 is transmitted from the parent unit 1 to the luminaire 2, and the luminaire 2 that receives the monitoring signal S1 transfers the monitoring signal to the other luminaires in a bucket brigade style.
[0032] Here, the status information includes any one of information regarding whether the luminaire is off, information regarding the presence or absence of communication with the luminaire, information regarding the lighting time of the luminaire, and information regarding the current dimming rate of the luminaire.
[0033] For example, the monitoring unit 31 transmits a monitoring signal S1 for inquiring about the current state of each luminaire 2 based on a user's operation via the operation unit 34. In this embodiment, the monitoring unit 31 transmits the monitoring signal S1 at a predetermined time interval (for example, every second).
[0034] The signal generating unit 32 generates a signal for causing the presenting unit 33 to present the monitoring information based on the received response signal S2. For example, if the presenting unit 33 is a display capable of displaying the status of each luminaire, the signal generating unit 32 generates an image signal that allows the status of each luminaire to be visually recognized. Also, for example, if the presenting unit 33 is a speaker, the signal generating unit 32 generates an audio signal that allows the user to recognize the status of each luminaire by voice.
[0035] In this embodiment, the monitoring unit 31 outputs a monitoring signal S1 to the luminaire at a predetermined time interval, and the signal generating unit 32 presents monitoring information for each luminaire based on a response signal S2 that is returned at that predetermined time interval.
[0036] The presentation unit 33 presents the monitoring information acquired from each luminaire. For example, a liquid crystal or organic EL display is used as the presentation unit 33. By checking the presentation unit 33, the user can monitor the status of each luminaire, which is updated at a predetermined time interval. In addition, the monitoring information may be presented to the user by voice through a speaker or the like, or the monitoring information may be presented to the user by the color or blinking of the light output from the lighting device. Note that the voice may include a simple signal sound, a melody, or the like, in addition to a sound reproduced by a human voice or a mechanical voice.
[0037] The operation unit 34 receives an operation from a user and outputs an operation signal based on the operation to the monitoring unit 31 and the signal generating unit 32. For example, the user can transmit a monitoring signal to each luminaire 2 by operating the operation unit 34. The operation unit 34 is configured with a touch panel or the like, and may be configured integrally with the presentation unit 33.
[0038] The configuration of the master unit 1 is not limited, and may include a storage unit that stores the state of each luminaire. For example, the storage unit may be a non-volatile memory that stores the type of malfunction of each luminaire, the number of malfunctions, the number of times a monitoring signal has been output, and the like.
[0039] 1, the parent unit 1 is placed in the front car (for example, the driver's compartment). For example, when a user monitors the luminaires, the user operates the operation unit 34 (parent unit 1) to output a monitoring signal to each luminaire 2 (child unit). The location where the parent unit 1 is placed is not limited, and it may be placed in the front car or the rear car, or in any of the cars connected between the front car and the rear car.
[0040] The lighting fixture 2 receives various signals from the parent unit 1, and transmits signals from the parent unit 1 to nearby lighting fixtures. In this embodiment, the lighting fixture 2 is disposed in the longitudinal direction of the vehicle body structure 12.
[0041] As shown in FIG. 3, the lighting device 2 includes a constant current circuit 41, a control unit 42, a first light-emitting unit 43, a second light-emitting unit 44, a communication module 45, and a memory 46.
[0042] The constant current circuit 41 outputs a predetermined DC current from the externally supplied power P. In this embodiment, the power P is supplied to the constant current circuit 41 by a static inverter (SIV) that extracts, for example, AC 100V from a DC power source from an overhead line.
[0043] The control unit 42 performs various controls on the lighting fixture. For example, the control unit 42 outputs a response signal via the communication module 45 in response to a monitoring signal from the parent unit 1. In addition to this, for example, the control unit 42 may control the constant current circuit 41 so as to obtain a current value necessary for the first light-emitting unit 43 and the second light-emitting unit 44 to emit light at a predetermined illuminance.
[0044] In this embodiment, the control unit 42 monitors a voltage V1 applied from the constant current circuit 41 to the first light-emitting unit 43 and the second light-emitting unit 44, a voltage V2 applied from the constant current circuit 41 to the first light-emitting unit 43, and a voltage V3 applied from the constant current circuit 41 to the second light-emitting unit 44. The control unit 42 transmits the values of the voltages V1, V2, and V3 to the parent unit 1.
[0045] The first light-emitting unit 43 and the second light-emitting unit 44 are configured to emit light upon receiving a DC power supply input from the constant current circuit 41, and to be capable of emitting a sufficient amount of light to illuminate the passenger compartment. For example, a plurality of light-emitting units may be arranged along the longitudinal direction, or any number and arrangement may be used depending on the amount of light emitted from adjacent slave units, advertisements within the railway vehicle, the environment outside the railway vehicle, etc.
[0046] In this embodiment, a plurality of LED elements such as white LEDs and warm white LEDs are used for the first light-emitting unit 43 and the second light-emitting unit 44. The lighting devices used for the first light-emitting unit 43 and the second light-emitting unit 44 may be the same or different.
[0047] The communication module 45 receives a monitoring signal S1 output from the parent unit 1. The communication module 45 also searches for a nearby child unit and transmits a monitoring signal to the child unit. In this embodiment, the communication module 45 outputs a response signal S2 to the parent unit 1. Note that in this embodiment, the communication module 45 corresponds to a response unit that wirelessly outputs a response signal including its own status information when it receives a monitoring signal directed to itself.
[0048] The memory 46 stores various information such as the state of the luminaire, etc. For example, the memory 46 is a non-volatile memory, and stores the cumulative lighting time of the luminaire and the PANID.
[0049] The slave unit is not limited to a lamp, and may be an in-car information screen that displays destinations and news, a security camera, a communication device, or other electronic device. In this case, for example, the master unit may have the function of a screen control device that controls the content displayed on the in-car information screen, or a monitoring device that detects abnormalities inside the car from images from security cameras.
[0050] Fig. 4 is a flowchart showing the luminaire monitoring process of the master unit 1. Fig. 5 is a diagram showing an example of the state of the luminaire 2.
[0051] 4, a monitoring signal is transmitted from the monitoring unit 31 to the luminaire 2 (step 101). The luminaire 2 outputs a response signal in response to the transmitted monitoring signal.
[0052] When the signal generating unit 32 receives a response signal (YES in step 102), the signal generating unit 32 generates an image signal for displaying the state of the luminaire based on the response signal. That is, the state of each luminaire is displayed on the display unit 33 (step 103).
[0053] 5, in this embodiment, the status of the lamp is classified into "normal", "LED open failure", "LED short failure", "communication abnormality", and "accumulated lighting time". The margin described below is, for example, 5V.
[0054] For example, if the following conditions are met, "Normal" is displayed. Voltage applied to the first light-emitting unit 43-margin≦V1-V2≦Voltage applied to the first light-emitting unit 43+margin Voltage applied to the second light-emitting unit 44-margin≦V1-V3≦Voltage applied to the second light-emitting unit 44+margin
[0055] For example, if the following conditions are met, an "LED open fault" will be displayed. V1-V2>Voltage applied to the first light-emitting section 43+margin V1-V3>Voltage applied to the second light-emitting section 44+margin
[0056] For example, if the following conditions are met, an "LED short circuit failure" will be displayed. V1-V2<voltage applied to the first light-emitting unit 43-margin V1-V3<voltage applied to the second light-emitting unit 44-margin
[0057] For example, if the following conditions are met, a "communication error" will be displayed. When a response signal from a lighting fixture to a monitoring signal is not received a specified number of times.
[0058] In addition, the "accumulated lighting time" is displayed when the accumulated lighting time of the luminaire is requested as a monitoring signal. For example, the accumulated lighting time is added up in one-hour increments to be used as a guide for equipment replacement.
[0059] In other words, the signal generating unit 32 determines the state of the luminaire based on the values of the voltages V1, V2, and V3, the presence or absence of a response, and the accumulated lighting time stored in the memory 46.
[0060] If the signal generating unit 32 does not receive a response signal (NO in step 102), it transmits a supervisory signal again (step 104). It is then determined whether the number of times the supervisory signal has been transmitted exceeds a predetermined number N (step 105).
[0061] When the state where no response to the monitoring signal is received exceeds a predetermined number of times N (YES in step 105), the signal generating unit 32 generates an image signal for displaying "communication abnormality." That is, "communication abnormality" is displayed on the display unit 33 (step 106).
[0062] FIG. 6 is a flowchart showing the response process of the luminaire 2.
[0063] 6, when the luminaire 2 receives a monitoring signal from the parent unit 1 (YES in step 201), it transmits a response signal including monitoring information to the parent unit 1 (step 202). For example, the luminaire 2 transmits the values of the voltages V1, V2, and V3 and the accumulated lighting time.
[0064] As described above, by wirelessly outputting a monitoring signal requesting monitoring information, which is information regarding the status of each luminaire, to each luminaire in sequence, it is possible to accurately monitor the status of each luminaire via wireless communication with less effort.
[0065] (Modification) 7 is a diagram showing a schematic diagram of a lighting system 200 according to a modified example of the present invention. Below, configurations different from the above embodiment will be mainly described, and configurations similar to those in the above embodiment will be denoted by the same reference numerals, and descriptions thereof will be omitted or simplified.
[0066] The lighting system 200 differs from the above-described embodiment in that it further includes a repeater 3 (23). The repeater 3 (23) is provided in each of the railway cars 10 and 20, and receives a signal transmitted from the master unit 1 or the luminaire 2.
[0067] Hereinafter, the luminaire 2 closest to the door will be referred to as luminaire 2n. Similarly, in the railway car 20, the luminaire 22 closest to the door provided at the coupling portion 5 connected to the railway car 10 will be referred to as luminaire 22a.
[0068] In the lighting system 200, a metal door (end plate) is provided on the end structure 14. Since this door blocks communication from the luminaire 2n to the luminaire 22a, communication is performed via the repeater 3.
[0069] The repeater 3 transmits the signal transmitted from the lighting fixture 2 to the lighting fixture 22 or repeater 23 of the adjacent railcar 20. Furthermore, the radio wave strength of the repeater 3 is greater than that of the master unit 1 and the lighting fixture 2, since the wireless signal passes through a door. For example, the radio wave strength of the master unit 1 and the lighting fixture 2 is -65 dBm, and the radio wave strength of the repeater 3 is -55 dBm.
[0070] Moreover, the repeater 3 is placed near the door to facilitate communication with the lamp 22 or the repeater 23 placed in the adjacent railcar 20.
[0071] In this way, even if a metal door is placed on the end body structure 14 between railway cars, by adding a repeater 3 with enhanced radio wave strength, wireless communication with the adjacent railway car 20 and even the last railway car is possible.
[0072] 7, the repeater 3 is provided independently of the lighting fixture 2, but this is not limited thereto. For example, the lighting fixture 2n disposed closest to the adjacent railcar 20 may function as the repeater 3. Similarly, two lighting fixtures disposed at both ends of the railcar 20 (closest to the door) may function as repeaters.
[0073] In this embodiment, the lighting fixture 2 functions as a slave unit, but the present invention is not limited to this, and the slave unit may be an in-car information screen that displays destinations and news, or an electronic device such as a security camera or communication device. In this case, for example, the master unit may be a screen control device that controls the content displayed on the in-car information screen, or a monitoring device that detects abnormalities inside the vehicle from images from a security camera. Similarly, the state of the lighting fixture (monitoring information) requested by the monitoring signal is not limited, and any information may be included in the monitoring information according to the type of the slave unit as described above.
[0074] In this embodiment, the monitoring information of all the luminaires is presented on the presentation unit 33, but this is not limiting, and only luminaires in an abnormal state may be displayed on the presentation unit 33. For example, an abnormal state is a state in which the child device cannot perform its original function, such as "LED open failure", "LED short failure", and "communication abnormality". In other words, the presentation unit 33 may present only the number of the luminaire in an abnormal state, the number of the vehicle on which the luminaire is installed, and the type of abnormal state.
[0075] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and various modifications can be made, and the configurations of the respective embodiments and modified examples can be combined. For example, in the present embodiment, a lighting system for controlling lighting fixtures installed in a railway vehicle has been described, but the lighting system may also be used for controlling lighting fixtures in each booth where objects that obstruct communication, such as metal walls or partitions, are installed in each predetermined section.
