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

FIG. 5 is a diagram illustrating an error processing method of a floor traffic light device according to an example of the present invention, and FIG. 6 shows a message to the output unit 210 when the control unit 200 performs a monitoring operation and when an error occurs. This shows an example of how information is displayed, and FIG. 7 is a diagram for supplementary explanation of the step (S400) of transmitting a state initialization request signal in the error processing method according to an example of the present invention.

As shown in Figure 5, the error processing method of the floor traffic light device according to an example of the present invention includes performing a monitoring operation (S100), receiving error occurrence information (S200), and stopping the monitoring operation (S100). S300), transmitting a state initialization request signal (S400), receiving a state initialization request signal (S500), and resuming the monitoring operation (S600).

In the step of performing a monitoring operation (S100), the control unit 200 may sequentially perform a monitoring operation for the operating state of each of the plurality of light emitting modules 100.

For example, in the step of performing a monitoring operation (S100), the control unit 200 performs a monitoring operation on the first light-emitting module 110 and then performs a monitoring operation on the second light-emitting module 120. As a result, a monitoring operation can be sequentially performed on all of the plurality of light emitting modules 100.

The control unit 200 may display monitoring information about the light emitting module currently performing a monitoring operation through the output unit 210 or transmit the monitoring information to a management center (not shown) through the communication unit 220.

In this stopping step, the control unit 200 displays monitoring information 211 and error occurrence information 213 for the last light emitting module (e.g., light emitting module No. 9) through the output unit 210. Monitoring operation can be stopped.

For example, as shown in (a) of FIG. 6, at 17:37:59 on June 23, 2021, while the control unit 200 is sequentially performing a monitoring operation for light emitting modules 7, 8, and 9, the first light emission When an error occurs in the module 110, as shown in (b) of FIG. 6, monitoring information 211 and an error for the last light emitting module (e.g., light emitting module No. 9) are displayed in the output unit 210. With the information 213 displayed, the operation of the control unit 200 may be stopped.

In this way, when the operation of the control unit 200 is stopped, light emission from the plurality of light-emitting modules 100 is stopped, or the operation of the control unit 200 is stopped while the plurality of light-emitting modules 100 are emitting light. It can be.

At this time, as shown in FIG. 7, the operator may connect the magnetic material M to the detection sensor 114 one by one for all of the plurality of light emitting modules 100. Accordingly, the magnetic material M may be brought into contact with each of at least some of the light emitting modules until the first light emitting module 110 among the plurality of light emitting modules 100 is searched.

Each light emitting module to which the magnetic material (M) is connected can detect an external signal through the detection sensor 114, generate voltage and current according to the detected signal, and transmit a status initialization request signal to the control unit 200. .

In the step of receiving a state initialization request signal (S500), the control unit 200 may receive a state initialization request signal from each of at least some light emitting modules.

In the step of receiving a state initialization request signal (S500), when the control unit 200 receives a state initialization request signal from a light emitting module other than the first light emitting module 110 and turns off the power, (b) of FIG. 6 Likewise, error occurrence information recorded in the output unit 210 may not be deleted.
