Here, the signal receiving module 210 may be configured to have a configuration corresponding to the panning module 130 and the tilting module 140 of the signal transmitting unit 100 to adjust the receiving angle.

The control module 220 controls to output a warning signal corresponding to the signal received through the signal receiving module 210 or to calculate and display the distance to the signal transmitting unit 100.

For example, when there is no signal received for a predetermined time or longer through the signal receiving module 210, it is determined that there is an object between the signal transmitting unit 100 and the warning unit 200, and a warning signal is output.

Further, when information (data) included in the received laser beam signal is included, the distance between the signal transmitting unit 100 and the warning unit 200 is calculated and displayed based on the received information (data). That is, it is configured to calculate the distance by checking the error between the time of transmitting the signal and the received time. In order to calculate the distance, a process of synchronizing the time of the signal transmitting unit 100 and the warning unit 200 is required.

Also, according to the design conditions, the control module 220 can be configured to transmit an alarm signal to the user's mobile device in connection with wired / wireless communication.

Here, the information of the warning signal transmitted to the mobile device may be configured to include a message set in the phone number of the pre-stored mobile device, a warning signal generation zone, and time.

According to such a configuration, the warning device according to the present invention is not limited to a railway, but can be applied to a variety of applications such as a boundary area of a crop, a fence, and the like.

The warning light 230 and the speaker 240 output a warning signal under the control of the control module 220. The warning light 230 visually outputs a warning signal and the speaker 240 audibly outputs a warning sound do.

The warning unit 200 may include a power supply module capable of operating the power supply module 200 and the power supply module of the warning unit 200 may be configured in the same manner as the power supply module of the signal transmission unit 100. Of course, the power supply module may be constructed using a battery, and may be constructed of electric energy accumulated through solar power generation using a solar panel according to other design conditions.

On the other hand, when a laser beam signal output by a laser diode is visually observed, it may be fatal to the eye.

Accordingly, in IEC standard 60825-1, it is required to comply with the rules for preventing damage to the human eye by the laser light emitted from the laser diode. This is not only a normal operation of the circuit, but also a prescription that must be met even in the case of a possible circuit fault, such as a short circuit in a particular device. In Korea, IEC 60825-1 complies with the laser safety standard (KS C IEC 60825-1), which proposes a laser output of less than 1 mW (Class II standard). In the present invention, the laser beam signal uses a laser diode, and such a rule must be obeyed.

For this reason, the signal transmitter 100 and the warning unit 200 may be configured with an indicator for confirming the operation state.

That is, the signal transmitting unit 100 and the warning unit 200 are configured to check the operation state with an indicator, and the operation state can be confirmed without observing the output laser beam with the naked eye. Likewise, the warning unit 200 is also provided with an indicator for confirming the operation state.

The warning device according to the present invention is self-supporting on the ground, and the output direction of the laser beam output by the panning module and the tilting module can be adjusted, so that the warning device is easy to install. Therefore, it is possible to easily detect an object approaching the railway from the work area by dividing the railway and the work area along the railway work area, thereby preventing the safety accident in advance.

In addition, since pairing of the pair of sensing devices is easy, it is easy to set the sensing zone.

According to such an effect, it is possible to provide a railway work platform as well as a railway platform to secure the position of the passenger when entering the railway car.

In addition, there is an advantage that it can be utilized as a device for guiding the stop position of equipment at each business site.

In addition, the access warning device according to the present invention can be used as an apparatus for preventing intrusion by installing in an area for protecting crops such as orchards and ginseng fields to prevent damage or theft of crops or installing them on a fence have.
