Description

Floor traffic light device and control method thereof}

The present invention relates to a floor traffic light device and a control method thereof, and more specifically, to a method and device that can individually switch the driving state of any one light-emitting module among the floor traffic light devices.

Recently, floor traffic lights have been developed to provide additional signal information to pedestrians by lighting a pedestrian signal on the floor of the crosswalk waiting line, thereby contributing to the convenience of walking and the prevention of traffic accidents. Due to the spread of smartphones, many pedestrians are looking at their smartphones instead of looking ahead when crossing a crosswalk, so their gaze is directed towards the ground. Therefore, floor traffic lights that are linked to the crosswalk traffic lights are installed on the ground to provide pedestrians with crosswalk signal information.

These floor traffic lights are generally installed between the crosswalk curb and a guidance block for the visually impaired, with the upper surface exposed to the outside and the side and lower surfaces buried in the sidewalk.

Meanwhile, in such a floor traffic light, if there is a problem with one of the plurality of light-emitting modules, the control operation of the controller is stopped, and the light-generating operation of the plurality of light-emitting modules is also stopped.

In this case, there is a problem in that each light emitting module buried in the sidewalk must be taken out and rechecked for abnormalities.

When the control unit 200 of the floor traffic light device of the present invention receives a request signal for state change from the first light emitting module 110, which is one of the plurality of light emitting modules 100, the control unit 200 makes a request signal according to the pattern of the request signal. 1 The power state of the light emitting module 110 can be switched.

Below, a more detailed description will be given of how such a floor traffic light device handles errors.

FIG. 5 is a diagram illustrating a control method of a floor traffic light device according to an example of the present invention, and FIG. 6 shows a method in which the first light emitting module 110 detects a signal from the outside in the transmitting step (S300) of FIG. 5. It is a diagram for explaining an example, and FIG. 7 shows that in the transmitting step (S300) of FIG. 5, the control unit 200 controls the light emission of the first light emitting module 110 according to the signal detection time or pattern. This is a diagram for explaining an example of switching states, and FIG. 8 is a diagram for explaining an example where the detection sensor 114 provided in each of the plurality of light emitting modules 100 includes first and second Hall sensors. .

As shown in Figure 5, the control method of the floor traffic light device according to an example of the present invention includes a setting step (S100), a turning on or turning off step (S200), a transmitting step (S300), and a switching step ( S400) may be included.

The control method of the floor traffic light device according to the present invention includes each of the plurality of light emitting modules 100 having a first Hall sensor as a detection sensor 114, and setting using the first Hall sensor (S100) ) and the case where the transmitting step (S300) is performed will be described as an example.

However, the present invention is not limited to this, and each of the plurality of light-emitting modules 100 according to the present invention may be provided with a first Hall sensor and a second Hall sensor as a detection sensor 114, and a plurality of light-emitting modules ( When 100) is provided with the first and second Hall sensors, the present invention performs the setting step (S100) using the first Hall sensor and the transmitting step (S300) using the second Hall sensor. It may be possible.

5 to 7, the control method of the floor traffic light device is first described as an example in the case where each of the plurality of light emitting modules 100 is provided with a first Hall sensor as the detection sensor 114, and in FIG. 8, a plurality of light emitting modules 100 are provided. The control method of the floor traffic light device will be described by taking as an example the case where each light emitting module 100 is provided with first and second Hall sensors as detection sensors 114.

In the setting step (S100), the control unit 200 may set an identification number for each of the plurality of light emitting modules 100. This setting step (S100) may be an initial setting step for operating the plurality of light-emitting modules 100 through the control unit 200, and the control unit 200 may set an identification number for each of the plurality of light-emitting modules 100. After giving, the control unit 200 can control each of the plurality of light emitting modules 100.

When each of the plurality of light emitting modules 100 is provided with only the first Hall sensor as the detection sensor 114, in the setting step (S100), each of the plurality of light emitting modules 100 receives a signal from the outside through the first Hall sensor. may be detected and a signal for setting an identification number may be transmitted to the control unit 200 in response to the detected signal.

The control unit 200 may receive a signal for setting an identification number and set an identification number for each of the plurality of light emitting modules 100.

To this end, in the setting step (S100), the operator can first press the reception standby button through the operation unit 230 provided in the control unit 200 to put the control unit 200 in a reception standby state.

Thereafter, as shown in FIG. 6 , the operator may connect the magnetic material M that generates a magnetic field to the first Hall sensor, which is the detection sensor 114 provided in each of the plurality of light emitting modules 100. Here, the magnetic material M may be a magnet, for example.

Each of the plurality of light emitting modules 100 to which the magnetic material (M) is connected transmits a signal to the control unit 200 in response to signal detection by the detection sensor 114, and the control unit 200 responds to the corresponding light emitting module. An identification number can be created and assigned.

In this way, the control unit 200 can sequentially assign an identification number to each of the plurality of light emitting modules 100.

Thereafter, in the turning on or turning off step (S200), the control unit 200 controls each of the plurality of light emitting modules 100 according to the identification number to turn on or turn off each of the plurality of light emitting elements. It can be driven by turning it off.

Thereafter, in the transmitting step (S300), the first light-emitting module 110 of the plurality of light-emitting modules 100 detects a signal from the outside through the detection sensor 114, and in response to the signal detection, the first light-emitting module 110 A request signal for changing the state of 110 may be transmitted to the control unit 200.

Here, the first light emitting module 110 may be one of the plurality of light emitting modules 100.

During a period when the control unit 200 drives the plurality of light-emitting modules 100, an error may occur in, for example, the first light-emitting module 110 among the plurality of light-emitting modules 100. In this case, control of the control unit 200 for all of the plurality of light emitting modules 100 may also be interrupted due to the first light emitting module 110 in which an error occurred.

In this case, the present invention switches the state of the first light-emitting module 110 in which an error occurred through the transmitting step (S300) to drive the remaining light-emitting modules except for the first light-emitting module 110 in which an error occurred. can be resumed.

Alternatively, in the present invention, the operating state of the first light emitting module 110 may be manually manipulated using the magnetic material M as needed through the transmitting step (S300).

To this end, the operator can connect the magnetic material (M) to the first Hall sensor provided in the first light-emitting module 110, as shown in FIG. 6, and the first light-emitting module 110 can be connected to the outside through the first Hall sensor. A signal from can be detected and a request signal for changing the state of the first light emitting module 110 can be transmitted to the control unit 200.

Thereafter, in the switching step (S400), the control unit 200 may receive a request signal from the first light-emitting module 110 and change the light-emitting state of the first light-emitting module 110.

Specifically, the control unit 200 controls the emission color, emission brightness, and emission pattern of the first light-emitting module 110 according to the detection time or detection pattern of the signal detected through the first Hall sensor of the first light-emitting module 110. Alternatively, any one of the power states can be switched.

For example, when an error occurs in the first light-emitting module 110, in the switching step (S400), the control unit 200 switches the first light-emitting module 110 when the light-emitting element of the first light-emitting module 110 is turned on. The power state of the first light emitting module 110 can be controlled so that the light emitting device 110 is turned off.

Alternatively, when the light-emitting element of the first light-emitting module 110 is turned off, the control unit 200 connects the magnetic material M to the first light-emitting module 110 according to the operator's needs. ) may be controlled to control the power state of the first light emitting module 110 so that the light emitting device is turned on.

Alternatively, if necessary, the operator may vary the time or connection pattern for connecting the magnetic material M to the first Hall sensor.

In this case, in the transmitting step (S300), the pattern of the request signal transmitted by the first light-emitting module 110 to the control unit 200 is an external signal detected through the detection sensor 114 of the first light-emitting module 110. It may vary depending on the detection time of the signal or the detection pattern of the signal. In the switching step (S400), the control unit 200 controls the first light emitting module 110 according to the pattern of the request signal received from the first light emitting module 110. ) can be switched.

As a specific example, for example, as shown in FIG. 7, whether the operator connects the magnetic material M to the first Hall sensor once for a long time (a) or once briefly (b) for a preset period P1, Depending on whether to connect twice briefly (c) or three times briefly (d), the control unit 200 may receive a request signal with a different pattern from the first light emitting module 110, and may make a request signal according to the pattern of the received request signal. 1 The power state of the light emitting module 110 may be changed (eg, turn on or turned off), or the light emission pattern, light emission color, or light emission brightness of the first light emitting module 110 may be changed to be different from the previous state.

As such, the control method of the present invention allows the operator to control the corresponding light emitting module through the control unit 200 by connecting the magnetic material (M) to the light emitting module from the outside without separately manipulating the control unit 200 as needed. , management of floor traffic light devices can be made easier.

So far, the case where the detection sensor 114 provided in each light-emitting module includes only the first Hall sensor and the setting step (S100) and the transmitting step (S300) are performed through the first Hall sensor has been described as an example. did. However, the present invention is not limited to this.

As another example, as shown in FIG. 8, the floor traffic light device of the present invention includes a first Hall sensor 114a and a second Hall sensor 114b as a detection sensor 114 in each of the plurality of light emitting modules 100. It can be included, and a setting step (S100) can be performed on the first Hall sensor 114a, and a transmitting step (S300) can be performed on the second Hall sensor 114b.

More specifically, in the setting step (S100), each of the plurality of light emitting modules 100 detects a signal from the outside through the first hall sensor 114a and sets an identification number in the control unit 200 in response to the detected signal. A signal for can be transmitted, and the control unit 200 can receive a signal for setting an identification number and set an identification number for each of the plurality of light emitting modules 100.

Additionally, in the transmitting step (S300), the second Hall sensor 114b of the first light emitting module 110, rather than the first Hall sensor 114a, may detect a signal from the outside and a request signal may be transmitted.

Here, the polarity of the magnetic material (M) detected by the first Hall sensor 114a and the second Hall sensor 114b may be the same, but differently, the first Hall sensor 114a and the second Hall sensor 114b It is also possible to detect magnetism of different polarities.

For example, each light emitting module may be configured so that the first Hall sensor 114a detects the N pole of the magnetic material (M), and the second Hall sensor 114b detects the S pole of the magnetic material (M).

Here, the first and second Hall sensors 114a and 114b may be positioned on both edges of the substrate, spaced apart from each other, on the top of the substrate.

In addition, first and second identification marks are displayed on the top of each of the first and second Hall sensors 114a and 114b in each of the plurality of light emitting modules 100, and the first identification mark located on the top of the first Hall sensor 114a The shape of the mark (not shown) may be displayed differently from the shape of the second identification mark (not shown) located on the top of the second hall sensor.

For example, the first and second identification marks are located in an embossed form on the outer surface of the upper enclosure 112a, like the identification mark 114M described in FIG. 2, but the embossed outlines have different shapes, It can be formed with different types of intaglio engraved on the same embossed shape.

For example, the first identification mark may be formed in a rectangular embossed shape, and the second identification mark may be formed in a circular embossed shape, or both the first and second identification marks may be formed in a circular embossed shape, and the first identification mark may be formed in an embossed shape in a circular shape. may be formed by engraving an N-shaped engraving on a circular embossing, and the second identification mark may be formed by engraving an S-shaped engraving on a circular embossing.
