Description

Smart safety display device with remote diagnosis and independent control functions for signaling devices

[0001] The present invention relates to a smart safety display device having remote diagnosis and independent control functions for a signal device. More specifically, the invention comprises a signal device controller configured to control the operation of a signal device according to the reading of an operation signal of a road traffic signal, such as a vehicle signal light or a pedestrian signal light, from a road signal reading unit; a serial communication cable communicating a control signal for the operation of the signal device; a CDSID signal device configured to light up in conjunction with a road signal; and a CDSID communication unit configured to receive an external ID coding signal via light to the CDSID signal device and perform ID assignment and operation coding. By receiving the input of ID assignment and operation coding to the signal device as an external optical signal through the CDSID communication unit and setting it, the invention aims to facilitate the installation and program setting of multiple signal devices in a compatible manner, enable smooth monitoring through ID management, ensure clear and systematic operation and management of the signal device, and further enable independent control of the signal device.

[0002] Here, the safety indicator device controls the lighting of signal devices such as vehicle traffic lights, pedestrian traffic lights, safety indicator lights, auxiliary vehicle traffic lights, crosswalk projection lights, and marker lights, which are installed in connection with the road for the safety of pedestrians and vehicle drivers.

[0003]

[0004] The safety display device described above is composed of a road signal reading unit that reads an operation signal from a road traffic signal, such as a vehicle signal or a pedestrian signal, a signal device controller configured to control the operation of the signal device according to the operation signal of the road traffic signal from the road signal reading unit, and a signal device controlled by the signal device controller.

[0005]

[0006] In such a safety display device, when the road signal reading unit reads a lighting signal from a road traffic signal, such as a vehicle signal or pedestrian signal, and transmits it to the signal device controller, the signal device controller supplies power to the signal device, causing the signal device to light up.

[0007]

[0008] However, the safety indicator device described above is configured to light up by applying power as a safety indicator signal from the signal device controller, so the control operation of the signal device is unclear and independent control is impossible, and there was a problem in that some parts of the signal device's configuration could not be applied to other signal devices.

[0009]

[0010] In addition, conventional signal devices lack individual IDs, making it difficult to monitor installed signal devices. Even if they have IDs, they are installed arbitrarily during the on-site installation process, which makes systematic setting and management difficult.

[0011]

[0012] Accordingly, the present invention aims to solve the problem that the safety indicator device described above is configured to simply light up by applying power as a safety indicator signal from a signal device controller, which makes the control operation of the signal device unclear and prevents independent control, and makes it difficult to systematically set up and manage the signal device due to the lack of an individual ID in the management of the signal device.

[0013]

[0014] That is, the present invention relates to a safety display device comprising: a road signal reading unit configured to read an operation signal of a road traffic signal from a road traffic signal; a signal device controller configured to control the operation of a signal device according to the reading of the operation signal of the road traffic signal from the road signal reading unit; a power cable configured to supply power for the operation of the signal device from the signal device controller to the signal device; a serial communication cable configured to communicate a control signal for the operation of the signal device from the signal device controller to the signal device; and a CDSID signal device configured to light up in conjunction with the road traffic signal, wherein the CDSID signal device comprises a CDSID communication unit that receives an ID coding signal from the outside via light and performs ID assignment and operation coding.

[0015]

[0016] In addition, the present invention is characterized in that the CDSID communication unit comprises a CDS optical sensor that recognizes an optical signal and a communication processing processor that receives the recognized optical signal, is assigned an ID, and performs operation coding, and is equipped with an ID optical coding input device that irradiates light to the CDSID communication unit of the CDSID signal device to communicate.

[0017]

[0018] Accordingly, the present invention comprises a serial communication cable that communicates a control signal for the operation of a signal device in a signal device controller, a CDSID signal device equipped to light up in conjunction with a road signal, and a CDSID communication unit that receives an external ID coding signal via light to the CDSID signal device and assigns an ID and performs operation coding. By using an ID optical coding input device to input an external optical signal to the signal device and input the ID assignment and operation coding to the CDSID communication unit from the outside, the installation and program setting of multiple signal devices can be easily and compatiblely performed, individual monitoring of signal devices can be smoothly carried out with individual IDs, thereby ensuring clear and systematic operation and management of signal devices, and furthermore, having the effect of independent control of signal devices with individual IDs.
