Description

  The present invention relates to a line-of-sight guidance system that performs a flashing light emission operation synchronized as a whole by installing a plurality of self-luminous line-of-sight guidance marks along a side edge of a road and causing each line-of-sight guidance mark to blink.

  Conventionally, a self-luminous gaze guidance sign that alerts the vehicle driver and guides a detour course of the vehicle at a construction site on the road or a work location that occupies a part of the road has been installed. Yes. In these devices, in order to improve the line-of-sight guidance effect due to flashing light emission, the flashing light emission timings of a plurality of line-of-sight guidance indicators that are simultaneously aligned and flashing simultaneously are flashing simultaneously, or sequentially giving time differences according to the order of installation. A relay flashing method that flashes light is used.

  In such devices, the timing of the flashing operation is synchronized during installation, and the timing deviation is corrected by receiving time signal information and radio clock signals included in the broadcast radio waves in order to prevent the flashing timing from being shifted over time. Or, as shown in Patent Document 1, a gaze guidance mark to be a key station is set among a plurality of gaze guidance signs installed, and a radio synchronization signal transmitted from the key station device is used as a terminal device. Proposals have been made to synchronize the blinking operation by sequentially sending to the gaze guidance mark.

Moreover, as shown in Patent Document 2, address numbers are set in advance to a plurality of visual guidance indicators, and each visual guidance indicator selects and receives a blinking control signal transmitted from the master device, thereby synchronizing the blinking operation. Has also been proposed.
Japanese Patent Publication No. 5-34445 JP-A-9-88019

  In the apparatus of Patent Document 1, a wireless synchronization signal is transmitted from a gaze guidance mark serving as a key station to a gaze guidance mark located next to the gaze guidance mark located next to the gaze guidance mark that is received next. By relaying, the timing of the light emission operation is adjusted as a whole for multiple visual guidance indicators, and there is no problem with the simultaneous flashing method in which the entire visual guidance indicator flashes almost simultaneously, but the relay flashing method that flashes sequentially and emits light with a time difference In this case, the light emission operation may be uneven. Because the relay blinking effect is obtained for the first time by emitting light at regular intervals in the order in which the line-of-sight guides are arranged, when the transmitted synchronization signal reaches the line-of-sight guide point further ahead of the next line-of-sight guide mark, The line-of-sight indicator that has received the synchronization signal blinks at the same timing, and the light emitting part that moves to the next one by one partially emits light at the same time, causing disturbance in the light emitting operation. It ends up.

  In this respect, in Patent Document 2, an address number is set for a plurality of line-of-sight guidance signs, a flashing control signal synchronized in advance by the master device is generated, and each line-of-sight guidance having an address number based on the flashing control signal is generated. By flashing the target, the timing setting for synchronizing the individual line-of-sight guides is not required, and the flashing light emission is easily synchronized. However, it is assumed that all installed visual guidance indicators receive the blink control signal from the master device, and it is necessary to enhance the transmission / reception function of the blink control signal. Therefore, a master device having a signal transmission function and a slave device having a signal reception function are prepared for exclusive use, and the flashing control signal is communicated, and there is a problem in that the size of the device cannot be avoided. .

  The present invention has been made in response to the above-described conventional problems, and a gaze guidance mark that can perform a flashing timing synchronization correction between devices of a plurality of gaze guidance signs installed with a simple configuration and with certainty. The purpose is to provide a system.

  In order to achieve the above object, in the light-emitting display device according to claim 1, a plurality of light-emitting line-of-sight guides are installed at intervals, and each light-emitting line-of-sight guide is made to emit light at a predetermined timing. In the line-of-sight guidance system that performs flashing light emission operation synchronized with the entire light-emitting line-of-sight guide mark, each light-emitting line-of-sight guide mark has an operation switch for switching operation start and stop of the light-emitting line-of-sight guide mark, and A unique address value corresponding to the number of units, an address data storage unit that stores a plurality of address identification signals corresponding to each unique address value in advance, a control unit that controls the blinking operation of the light emitter, and other light emitting visual guidance indicators As a light emission synchronization signal for designating the light emission operation timing, it is output from the synchronization signal transmission unit that outputs the address identification signal and other light emitting visual guidance indicators. A synchronization signal receiving unit for receiving a light emission synchronization signal, and receiving an operation start operation by the operation switch for all the light emitting visual guidance indicators to be installed, within another first predetermined time from the operation start operation When the address identification signal output by the light emitting gaze guidance mark is not received, the self address is set to the minimum address value and the address identification signal corresponding to the self address value is output, while the first after the operation start operation by the operation switch. When an address identification signal output by another light emitting gaze guidance mark is received within a predetermined time, an address corresponding to the own address value is set by setting the address to an address value corresponding to the next order of the received address identification signal A line-of-sight guide system characterized in that different unique address values are set for all light-emitting line-of-sight guides by outputting an identification signal Proposed.

  Each light emitting visual guide that has completed the setting of the unique address value outputs an address identification signal corresponding to its own address value as a light emission synchronization signal when the second predetermined time has elapsed after the first predetermined time has elapsed. It is desirable to do.

  In addition, each light emitting line-of-sight guide mark for which the setting of the unique address value has been completed has a light emitting line of sight having an address value corresponding to the preceding order of its own address value within a second predetermined time after the first predetermined time has elapsed. It is desirable to receive only the address identification signal output from the guide mark as the light emission synchronization signal and start the blinking light emission operation at the timing given to the received light emission synchronization signal.

  In addition, each light-emitting gaze guidance mark receives a light-emission synchronization signal and starts a blinking light-emission operation with a fixed period after a lapse of a certain time, whereby a light-emission operation in which the light-emitting points sequentially move as a whole of a plurality of light-emitting gaze guidance marks It is desirable to do.

  According to the present invention, in order to install and start using the light-emitting visual guidance indicator, only operate each operation start switch from the state where the use is not started with respect to the plurality of light-emitting visual guidance indicators to be installed. Thus, a unique address number can be set for each of the luminous visual guidance indicators in which no address number is set.

  In the state before the start of use of the device, it is possible to handle the plurality of luminescent line-of-sight guides to be installed as all having the same specifications without being conscious of the address number for identifying the individual. As a result, an individual address is automatically set for each line-of-sight guidance indicator, so that the user has to take care of storage management and installation work when actually using the product as well as at the product manufacturing stage. Can be greatly simplified.

  In addition, the light-emitting gaze guidance mark set with the individual address number is used for receiving processing using only the address identification signal output by the gaze guidance mark having an address value corresponding to the preceding order of the set address number as the light emission synchronization signal. In performing the light emission operation, the light emission synchronization signals can be transferred one by one in the order in which the line-of-sight guides are arranged, and it is possible to perform an appropriate light emission operation with no visual disturbance. In particular, it is possible to appropriately perform the light emission operation of the relay blinking method by performing the blinking light emission operation of a certain period after each visual guidance indicator receives the light emission synchronization signal from the preceding visual guidance indicator and after a predetermined time has elapsed. it can.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.
1A and 1B are external views of a light-emitting line-of-sight guide mark showing an embodiment of the present invention, where FIG. 1A is a front view and FIG. 1B is a rear view. The light-emitting line-of-sight guide specimen 1 is composed of a resin-molded light-emitting portion 2 and a main body case 3, and an infrared light receiving element 4 as a synchronization signal receiving portion is provided on the front side of the main body on the outer surface of the main body case 3. An infrared light emitting element 5 serving as a synchronization signal transmission unit is provided on the back side of the main body on the outer surface of the case 3. Although not illustrated, the front surface of the light emitting unit 2 is covered with a translucent lens cover, and an LED (light emitting diode) that emits light for visual line guidance is disposed inside the lens cover. Reference numeral 6 denotes a power switch as an operation switch, and the light emission operation start and stop of the light emitting unit 2 are switched by an on / off operation of the power switch. Inside the main body case 3, a secondary battery that stores electric power for operation and a control unit that controls the operation of the entire luminous visual guidance indicator are built in.

  Next, the internal configuration of the embodiment of the present invention will be described with reference to FIG. Reference numeral 11 denotes a secondary battery, which supplies power for operating the apparatus to the entire light emitting visual guidance indicator via an operation switch (power switch) 6. A control unit 12 controls the blinking operation of the light emitting unit 2, reads data related to the light emission blinking cycle stored in the storage unit 13, and blinks the LEDs disposed in the light emitting unit 2 through the light emitting unit drive circuit 14 to a predetermined blink. Light emission is driven at a cycle. Further, the control unit 12 corrects the operation timing of the light emission blinking operation of the light emitting unit 2 based on the synchronization signal from another light emitting visual guidance indicator received by the synchronization signal receiving unit 4 (infrared light receiving element). Reference numeral 15 denotes an address data storage unit, which is a set of a plurality of (eight in the present embodiment) light emitting line-of-sight guides installed at an installation location such as a road, and address numbers corresponding to the number of units constituting one set, An address identification signal corresponding to each address number is stored. This address identification signal is an 8 in which different pulse widths are assigned to numbers “1” to “8” in order to distinguish “1” to “8”, which are the address numbers of eight units constituting one set. This type of pulse signal is transmitted from the synchronization signal transmission unit 5 to the outside as a pulse signal corresponding to its own address number set in accordance with an address number setting operation described later. The transmitted pulse signal is received as an address identification signal in the synchronization signal receiving unit 4 of another light-emitting line-of-sight guide mark.

Next, the operation of the embodiment of the present invention will be described. First, the address number setting operation will be described based on the flowchart of FIG. Address number setting means that when a light emitting gaze guidance mark that is not emitting light is installed at the installation location and the operation is started, each of the plurality of light emitting gaze guidance signs to be installed is addressed in turn. Points to the process of setting.
First, the eight light-emitting visual guidance indicators constituting one set are arranged close to each other in a row at hand, and the synchronization signal transmission unit 5 of the light-emitting visual guidance guide located on the front side of the light-emitting visual guidance guides arranged in the front and rear, It is placed in a positional relationship facing the synchronization signal receiving unit 4 of the light emitting visual guidance indicator located on the rear side. In this state, the power switch 6 of each light emitting visual guidance indicator is turned on from the state where the operation is stopped (S1). When the power switch 6 is turned on, power supply from the secondary battery built in the main body case 3 to each unit is started, and the flashing operation of the light emitting unit 2 is started (S2). Incidentally, the flashing operation performed at this point is executed based on the timing at which the control unit 12 reads the flashing flash data from the storage unit 13, and is completely different from other line-of-sight guidance signs constituting the same set. Performed at independent timing. Next, the synchronization signal receiving unit 4 checks whether or not an address identification signal transmitted from the light emitting visual guidance indicator located immediately before is received (S3). If the address identification signal is received, it is determined that the received address identification signal is a signal that is located immediately before the light emitting visual guidance indicator arranged in a line, and the address number represented by the received address identification signal is set. The address number obtained by adding 1 is set as its own address (S4). As a result, an address number corresponding to the next order of the luminous visual guidance indicator located immediately before is set in accordance with the order of arrangement in a line. After that, it waits for the elapse of a first predetermined time (3 seconds in this embodiment) after the power switch is turned on (S5), and an address identification signal corresponding to the set address number is sent from the synchronization signal transmission unit 5 Output (S8). The address identification signal output in this way is received by the sync signal receiving unit 4 of the luminous visual guidance indicator located immediately after.

  By the way, in the above step (S3), when the first predetermined time (3 seconds in the present embodiment) elapses without receiving the address identification signal in the synchronization signal receiving unit 4 (S6), the front position emits light. It is determined that there is no line-of-sight guidance mark, and the address number “1” is set as its own address (S7). Thereby, it sets as the 1st light emission gaze guidance mark of 8 units | sets of the light emission gaze guidance mark which comprises 1 set. Subsequently, an address identification signal corresponding to the own address number “1” is output from the synchronization signal transmission unit 5 (S8). The output address identification signal is received by the light emitting gaze guidance mark located immediately after, and the address number “2” is set to the light emitting gaze guidance sign immediately after according to the above-described operation, and thereafter, the eight units arranged in proximity to each other in the same manner. Address numbers “1” to “8” are set in the luminous line-of-sight guidance signs. It should be noted that for the light-emitting visual guidance indicator with the address number “8” located at the end, since there is no other light-emitting visual guidance indicator behind, the above step (S8) is not executed, and the address number “8” is set. When set, the address identification signal is not output.

Here, the address identification signals corresponding to the address numbers “1” to “8” for the eight units are as follows.
Address number “1”: Pulse address number “2” having a pulse width of 50 milliseconds: Pulse address number “3” having a pulse width of 60 milliseconds: Pulse address number “4” having a pulse width of 70 milliseconds : Pulse address number “5” having a pulse width of 80 milliseconds: Pulse address number “6” having a pulse width of 90 milliseconds: Pulse address number “7” having a pulse width of 100 milliseconds: 110 milliseconds Pulse address number “8” with pulse width: None (no output)

Next, the light emission synchronization correction operation according to the embodiment of the present invention will be described with reference to the flowchart of FIG.
When the address number setting is completed by executing the processing shown in FIG. 3 and the first predetermined time has elapsed (S11), an address identification signal corresponding to the order of the own address is generated based on the set own address number. It is confirmed whether or not the signal is received by the synchronization signal receiver 4 (S12). Here, the address identification signal corresponding to the preceding order received is a light emission synchronization signal, and only the light emission synchronization signal output from the light emitting visual guidance indicator at the immediately preceding position having the previous address number is received. When this sync signal is received by the sync signal receiving unit 4, the flashing operation of the light emitting unit 2 is reset after 200 milliseconds from the time of reception, and the flashing operation in a predetermined cycle (in this embodiment) is resumed. (S13). As described above, at the stage when the power switch 6 of the light-emitting line-of-sight guide is turned on, the blinking operation is performed depending on the operation timing of the power switch. The timing is corrected to be synchronized with the timing of the blinking operation performed by the light emitting visual guidance indicator. Next, it is determined whether or not a second predetermined time (18 seconds in the present embodiment) has elapsed since the first predetermined time has elapsed (S14). An address identification signal corresponding to its own address number is output from the synchronization signal transmission unit 5 toward the light-emitting line-of-sight guide (S15). The address identification signal output in this way is received by the sync signal receiving unit 4 of the light emitting visual guide having the next address number as the light sync signal. Since the light emitting visual guide having the address number “1” positioned at the head of the eight light emitting visual guides constituting one set does not receive the light emission synchronization signal from the front, S12) and (S13) are not executed, and after waiting for the second predetermined time to elapse from the time when the first predetermined time has elapsed, the light emission based on the light emission blinking operation being performed according to the operation timing of the power switch 6 The synchronization signal is output to the light emitting visual guidance indicator having the address number “2”.

  The address number setting operation and the light emission synchronization correction operation performed continuously as described above will be confirmed based on the timing chart of FIG. First, eight light-emitting line-of-sight guides constituting one set are mounted on a dedicated mounting tray or the like, and the power switch 6 of each light-emitting line-of-sight guide is turned on in order from the top in a state of being arranged close to one row. To do. When the power switch is turned on, the light emission blinking operation of the light emitting unit 2 is started, and the blinking operation with a light emission time of 80 milliseconds is executed in a cycle of 1 second. In parallel with this, the synchronization signal receiving unit 4 confirms whether or not a previous address identification signal has been received from the time when the power switch is turned on until the first predetermined time of 3 seconds elapses. When the first predetermined time of 3 seconds elapses, the synchronization signal transmission unit 5 outputs an address identification signal corresponding to its own address. Subsequently, a light emission synchronization signal that is emitted by the preceding light emitting line-of-sight guidance mark from the time when the address identification signal is output (when the first predetermined time of 3 seconds has elapsed) until the second predetermined time of 18 seconds elapses. Check whether or not is received. If the light emission synchronization signal is received, the blinking operation of the light emitting unit 2 is reset, and the blinking operation is restarted at the timing of light emission ON for 80 milliseconds 200 milliseconds after the reception of the synchronization signal. On the other hand, the synchronization signal transmitting unit 5 outputs a light emission synchronization signal toward the next-order light emitting visual guidance indicator when the second predetermined time 18 seconds elapses.

  By performing the above operation for each of the eight light-emitting visual guidance indicators that constitute one set, an address number is automatically set for each of the eight light-emitting visual guidance indicators. It is possible to perform relay flashing light emission that sequentially flashes light with a time difference. Then, by installing the light emitting gaze guidance sign at the installation place such as the road according to the order of the address numbers, for example, the relay flashing light emission is performed in the order of the address numbers “1” to “8” toward the vehicle traveling direction, and the detour course Guidance and warning signs can be performed.

  In addition to a light-emitting line-of-sight guide having a substantially circular light-emitting portion, the present invention provides a sign for guiding a traveling direction by arranging a plurality of substantially letter-shaped light-emitting modules, or an arrow indicating a road boundary during snowfall. It can be used for a signage device that installs a plurality of blade signage devices and the like and performs a warning sign toward the vehicle driver.
