DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, with respect to an example of a first embodiment of the present invention, maintenance of a self-luminous road stud embedded in a road will be described with reference to FIGS. FIGS. 1A and 1B show a self-luminous road stud A configured so that the operation state thereof can be easily maintained and inspected by applying the maintenance display system of the present invention (a): a top view, and (b): a sectional structure. FIG. 3 is a diagram showing a light emission of the luminous body A1 in accordance with a preset operation program by a control signal issued from a control circuit A4 incorporated in a control board using the power storage device A2 as a power supply. That is, A3 is an illuminance sensor, and when the illuminance falls below a certain set value at dusk or a steep storm, an illuminance detection signal is sent to the control circuit A4, and as a result, the illuminant A1 is set to a predetermined predetermined value. An operation (repetition of blinking, etc.) is performed based on a control signal of an operation program (for example, blinking every fixed number of seconds).

The power generated by the solar cell A5 is stored in the power storage device A2 to stably supply power to the luminous body A1, and when the power stored in the power storage device A2 decreases, the power storage device A2 The power storage device protection circuit A6 is provided on the control board in order to prevent the deterioration of itself. That is, when the generated power is small due to the continued bad weather and the power storage becomes lower than a certain set power, the light emitting device is operated until the power storage device protection circuit A6 is activated to recover the stored power of the power storage device A2. The power supply to A1 is temporarily stopped. The self-luminous road stud A has a built-in maintenance check circuit for maintenance and inspection, and a light emission indicator of the maintenance lamp 1 indicating that the maintenance check is in operation is turned on.
During the operation of the maintenance check circuit, the power storage device protection lamp 2 is turned on when the power storage device protection circuit A6 is operating, and the sensor detection lamp 3 is turned on when the illuminance sensor sensing is normally performed. 1,
(Power storage device) protection lamp 2, (sensor) sensing lamp 3
The operation state can be easily confirmed by each of the light emitting display means.

[0012] As a result, when there is a problem that the luminous body A1 does not blink in the related art, the cause is that the power storage device protection circuit A6 is operating and the power supply to the luminous body A1 is temporarily stopped. It is unknown whether the illumination sensor A3 does not operate normally or whether it is caused by another failure. However, it is possible to presume a general defect by each light emitting display unit for maintenance check by the maintenance display system of the present invention. This makes it easier to take countermeasures. In addition, as shown in FIG. 1, by removing the fixing screw A8 fixing the plastic lens body A7 of the self-luminous road tack A, the inspection can be performed without digging the road tack every time when there is a problem as in the prior art. If repairs can be made, the time required for restoration of the faulty location will be reduced, and traffic interruptions performed during inspections and repairs will be performed in the minimum necessary time, making maintenance and inspection extremely easy. Becomes In FIG. 1, reference numeral A9 denotes a waterproof packing made of rubber or the like, which is provided inside the main body in which the power storage device A2 of the self-luminous road stud A is installed and the control circuit A4.
Is designed to perform a waterproof function so that moisture such as rainwater does not enter the inside of a control board, a light emitting unit, or the like in which is incorporated.

In the above description, the case where the operation of the maintenance check circuit is set to always operate in the control circuit A4 has been described. However, for example, a time period limited by a signal based on a sensing signal sent from the sensing sensor A3 is described. A program that operates only on the belt may be set, the light emission sign is made and the maintenance check circuit is paused at night when power consumption is high, or conversely, during several hours at midnight when the traffic volume of the vehicle is small. It may be set so that maintenance and inspection are performed by operating only the operation.

Next, the operation of the self-luminous road stud A described in the first embodiment to which the maintenance display system of the present invention is applied will be described in detail with reference to a block diagram of FIG. Will be described. In the block diagram showing the operation of the self-luminous road tack A in FIG. 2, a maintenance lamp 1 for maintenance confirmation is provided, and a power output 12 for confirmation of maintenance is constantly output. Electricity is applied to the base terminal of the connected transistor 13 by the switching effect of the transistor, and the maintenance lamp 1 indicating "maintenance circuit is operating" is lit. In the figure, the reference numeral 16 connected to the collector terminal of the transistor 13 is an operating power supply which is constantly supplied from the power storage device. Therefore, if the maintenance lamp 1 itself does not light up, it is first checked whether there is any abnormality in the power storage device. Alternatively, the circuit of the maintenance lamp 1 may be checked. That is, the maintenance lamp 1 indicates whether or not the power storage device is working, and in that sense, functions as a power supply operation lamp.

The power storage device A2 is provided in the main body of the self-luminous road stud A. The power generated by the solar cell A5 is stored in the power storage device A2 so as to stably supply the power irrespective of fluctuations in the amount of solar radiation. However, as described in detail above, when the amount of power consumption is large and the stored power is reduced, for example, when the amount of solar radiation is small such as rainy weather continues, when the battery is used as the power storage device A2, A protection circuit is incorporated to prevent the battery itself from deteriorating due to an excessive load. When the power storage device protection circuit is activated and the output 22 is made, the protection terminal is connected to the base terminal of the transistor 23. As a result, the protection lamp 2 is turned on, which means that the protection circuit is in operation.

Further, as described above, the self-luminous road stud A has a built-in illuminance sensor A3, which operates when the illuminance falls below a certain set value at dusk or a steep storm, based on the illuminance detection signal. Then, the luminous body A1 is operated based on a control signal of a predetermined operation program which is set. At the same time when the control signal is transmitted, an output 32 is made, and the output is applied to the base terminal of the transistor 33, so that the switching effect of the transistor 33 is obtained. Is generated, and the sensing lamp 3, which means "illuminance sensor is sensing", is turned on.

Next, a second embodiment of the present invention will be described.
An example of a vehicle approaching direction marking system for avoiding a collision at an intersection of vehicles traveling on two intersecting roads will be described with reference to FIGS. FIG. 3 shows an intersection 6 * 7 where the main road 7 and the sub road 6 intersect, and the vehicle detection device 63 with the built-in approach direction detection sensor B to which the present invention is applied.

A warning sign system C to which the present invention is applied, which is installed in front of the intersection 6 * 7 along the main road 7 from each of the vehicle sensing devices 63 and 65 only when a vehicle heading for the intersection 6 * 7 is detected from the vehicle. Is transmitted wirelessly to the warning sign devices 73, 74 in which the vehicles 6 and 7 are traveling on the main road 7 toward the intersection 6 * 7.
The system alerts the driver by alerting the driver of the approaching vehicle and the direction of approach.

FIG. 4 shows vehicle sensing devices 63 and 65 having a built-in maintenance confirmation circuit to which the present invention is applied.
Infrared rays emitted from the vehicles that have entered the detection areas 64 and 66 are converged by the Fresnel lens 81 and reach the heat-sensitive element to detect the vehicle. Only when a traveling vehicle heading for the intersection 6 * 7 is detected above, a warning sign device 7 separately installed from the transmitting antenna 82

It is.

In FIG. 3, when the vehicle sensing device 63 detects the vehicle 61 traveling on the sub road 6 toward the intersection 6 * 7 in the detection area 64, the vehicle sensing device 63 as described above.
The detection / detection process is performed at the vehicle, and it is determined that the vehicle is a detection target vehicle approaching the intersection 6 * 7, and the warning sign devices 73 and 74 are operated by radio, and the intersection 6 * 7 is driven on the main road 7. The driver or the like of the vehicle 71 traveling toward the vehicle blinks the right-facing arrow 95 of the warning sign board 91 in FIG. And alerts the driver while the main road 7
Vehicle 72 traveling from above in the opposite direction to intersection 6 * 7
5C of the warning sign device 74 of the warning sign device 91 blinks the left-facing arrow 96 to warn the driver or the like of the warning together with the blinking display of "car approaching!" To avoid the collision of the vehicle.

In FIG. 3, when the vehicle sensing device 65 senses the vehicle 62 moving away from the intersection 6 * 7 on the sub road 6 in the detection area 66, the vehicle sensing device 65 determines the detection and detection process. A control signal is not transmitted to the warning sign devices 73 and 74 excluding from the determination that the vehicle is approaching, and a malfunction due to infrared rays from the vehicle moving in the reverse direction is prevented.

In the case where the vehicle is approaching the intersection 6 * 7 at the same time from both sides of the sub road 6 in FIG. The detection process is performed and the vehicle sensing device 6
The warning sign devices 73 and 74 from the devices 3 and 65, respectively.
, A blinking arrow indicating the approaching direction of the vehicle is displayed together with the blinking display of “car approaching!”. In this case, the blinking display of the arrow is performed according to a preset program, for example, a warning display of a rightward arrow 95 shown in FIG. 5B and a warning display of a leftward arrow 96 shown in FIG. A warning sign is made by a vehicle approach warning device which is performed alternately or in which arrows pointing in both right and left directions are arranged.

In the above-described vehicle approach direction indicating system for avoiding a collision at an intersection at an intersection shown in FIGS. 3 to 5, the maintenance display device of the present invention includes a vehicle sensing device 63,
This is applied to the approach direction sensor B built in 65 and the warning sign system C built in the warning sign devices 73 and 74. Hereinafter, the operation of the approach direction sensor B and the warning signing system C shown in FIGS. 7 and 9 show the appearances of the vehicle sensing devices 63 and 65 and the warning sign devices 73 and 74 in which B and C are incorporated, (a) shows the appearance of the device in which they are incorporated, and (b) shows the present invention. 4 illustrates each operation panel of the maintenance display system.

When the maintenance switch 14 is turned on in the flowchart of FIG. 6 showing the operation of the approaching direction sensor B, the maintenance operation timer 11 is started and the maintenance confirmation power supply 10 is started for a predetermined period of time (for example, 30 minutes). The output 12 is output by the electricity, and the base terminal of the transistor 13 connected to the maintenance lamp 1 is energized, so that the maintenance lamp 1 indicating “maintenance circuit is operating” is turned on. It should be noted that 16 connected to the collector terminal of the transistor 13 corresponds to FIGS.
5 is an operating power supply that is constantly supplied from a power storage device to operate each of the vehicle sensing devices 63 and 65.

The battery (storage battery) used as a power storage device in the present embodiment is located in the main body of the vehicle detection devices 63 and 65 having the approach direction detection sensor B built therein, and the solar cell shown in FIG. The power generated by the cell 83 is stored to supply power stably irrespective of fluctuations in the amount of solar radiation. The protection circuit 21 is incorporated to prevent the battery from being deteriorated due to an excessive load applied to the battery when the stored power decreases due to a large power consumption. Therefore, when the battery protection circuit 21 is activated, the output 22 is output from the circuit. As a result, the base terminal of the transistor 23 is energized, so that energization occurs due to the switching effect of the transistor. The protection lamp 2 is turned on. By confirming the operation of this battery protection circuit,
In the unlikely event that the approach direction sensor B does not operate, it is relatively easy to determine the status of the malfunction, such as whether power is not being supplied due to the operation of the battery protection circuit or a malfunction of other devices. I can judge.

When the sensing element of the approaching direction sensing sensor B senses a vehicle passing through the sensing area, the sensing / detection process is executed to detect the target vehicle (in the example of FIGS. And a signal is output to the transmitting unit in order to transmit the signal to the warning signing device wirelessly. Therefore, the detection output 32 is taken out from the object sensing circuit 31 and output for maintenance confirmation, and the base terminal of the transistor 33 is energized and energized by the switching effect of the transistor to turn on the sensing lamp 3, and “ And that the target vehicle is being detected ". By enabling the sensing and detection confirmation of this sensor, the work of sensing → detection → operation confirmation (actually confirming the actual sign visually), which has conventionally been performed by two workers, is reduced to one.
It can be checked immediately by human workers.

The maintenance lamp 1, the protection lamp 2 and the detection lamp 3 are provided on the operation panel 80 of the approach direction detection sensor B shown in FIG. It is lit and confirmed. In addition,
Reference numeral 14 in the figure denotes a maintenance switch which is turned on at the beginning of the checking procedure, and reference numeral 15 denotes a maintenance switch which is used when repairs and the like are performed by extracting a defect through inspection and the operation is completed and restarted to confirm operation. Reset (restart)
Switch.

Next, in the flow chart showing the operation of the warning signing system C shown in FIG.
Is turned on, the maintenance operation timer 11 is activated, the voltage is supplied from the maintenance confirmation power supply 10 for a set time (for example, 30 minutes), and the output 1 is output.
2 is output, the base terminal of the transistor 13 connected to the maintenance lamp 1 is energized, and the maintenance lamp 1 indicating "maintenance circuit is operating" is turned on. Reference numeral 16 connected to the collector terminal of the transistor 13 is an operating power supply which is constantly supplied from the power storage device to operate each function of the warning indicating devices 73 and 74 shown in FIGS.

The batteries (storage batteries) for operating the warning indicating devices 73 and 74 are also similar to the batteries for operating the vehicle sensing devices 63 and 65 described above.
In order to avoid the deterioration of the battery, a battery protection circuit 21 is incorporated, and when the protection circuit operates, an output 22 is taken out from the circuit and is applied to a base terminal of the transistor 23, thereby causing a switching effect of the transistor. , The protection lamp 2 is turned on when the protection circuit is in operation. Therefore, similar to the approach direction sensor B, the battery protection circuit 21
It is possible to easily determine whether the warning indicator system C does not operate due to the interruption of the power supply due to the operation of the battery protection circuit or the malfunction of other devices.

Subsequently, the wireless lamp 4, the receiver 1 lamp 46,
The receiver 2 lamp 49 will be described. When the vehicle detection / detection process is performed by the approach direction detection sensor B and the target vehicle detection is determined, the vehicle is wirelessly transmitted to the warning sign devices (warning sign devices 73 and 74 in FIGS. 3 to 5) and received. The signal is received by the wireless module 41 in the warning sign system C incorporated in the warning sign device via the antenna 92. The received signal is output as an operation signal for controlling a specific sign or the like by extracting the data signal from which the carrier wave has been removed in the wireless module 41.
When this signal output is applied to the base terminal of the transistor 43 as the output 42 of the wireless confirmation circuit, energization occurs due to the switching effect of the transistor, and the wireless confirmation lamp 4 is turned on during “radio reception”, and reception is normally performed. You can see that it has been done.

Incidentally, in many cases, a plurality of warning sign devices are used in the example of the vehicle approach direction sign system of FIGS. 3 to 5, and for example, when the vehicle is arranged as shown in FIG. A rightward arrow 95 must be displayed on the warning signing device 74 and a leftward arrow 96 must be displayed on the warning signing device 74, and the intended warning signing device must be accurately controlled. In the case of the second embodiment to which the present invention is applied, a plurality of channels are provided to avoid malfunctions, that is, in order to prevent interference at the time of reception, transmissions with different frequencies are made, or data setting is performed for each channel. A method of setting a unique pattern is used. Therefore, the ID (identity recognition) of the radio signal transmitted from the transmitter or the ID (identity recognition) of the data pattern must be matched with the ID (identity recognition) in the receiving circuit so as to be paired with the ID. The receiver 1 lamp 46 and the receiver 2 lamp 49 are provided for confirming the possibility.

That is, when the wireless module 41 has the receiving one circuit output 44 or the receiving two circuit output 47, the current is supplied to the base terminal of either the transistor 45 or the transistor 48, and the current is supplied by the switching effect of the transistor. Then, the receiving 1 lamp 46 or the receiving 2 lamp 49 is turned on, and it is confirmed that "output to the receiving 1 or 2 circuit". Therefore, when the wireless confirmation lamp 4 is lit while the display plate of the warning sign device is not operating, whether the transmitter ID (identity recognition) is different or the receiver ID (identity recognition) is one. It is possible to easily determine whether they have not done so. And, even if the construction conditions are changed during the installation work of this vehicle approach direction marking system, if the switching wiring is performed on the spot after confirming the output of the receiving channel at the construction site, immediately and Channels can be set reliably and quick construction can be performed.

At the end of the second embodiment of the present invention, a description will be given of the character confirmation lamp 5 relating to the lighting of the display panel of the warning sign system C. 5 from the wireless module 41 based on the control signal transmitted from the approach direction sensor B.
The character / arrow control circuit 51 is provided on the display board 91 of (b) and (c).
When the signal of the sign is issued via the switch, the output 52 is made and the base terminal of the transistor 53 is energized, so that the switching effect generated in the transistor 53 causes the energization to take place. The lighting of 5 is performed. Note that the display plate character 50 in FIG. 8 is a warning sign device that actually lights (the warning sign devices 73 and 7 in FIGS. 3 to 5).
4) indicates a sign on the display board 91, and the actual sign is connected to the character confirmation lamp 5 by a connector 55 and is monitored in synchronization with the actual sign.

The above-described display confirmation lamps of the maintenance lamp 1, the protection lamp 2, the wireless lamp 4, the character confirmation lamp 5, the receiving lamp 1 46, and the receiving lamp 49 are the warnings shown in FIG. Each indicator lamp is lit on the operation panel 90 of the marking system C to confirm. 14 is a maintenance switch which is turned on at the beginning of the check procedure, and 15 in the figure is repair and the like are performed by extracting a defect by inspection, and the operation is completed.
This is a reset (restart) switch used when the operation is confirmed by restarting.
