2 is a flowchart illustrating an autonomous inspection method of the ATC terrestrial signal autonomous inspection system according to the first embodiment of the present invention.

As shown in FIG. 2, the controller 130 of the ATC ground signal autonomous inspection system receives and analyzes the ATC ground signal in the state of driving of the electric vehicle (S101) (S102).

For example, the controller 130 analyzes whether the ATC terrestrial signal is received and the signal strength of the ATC terrestrial signal.

Through the analysis, the control unit 130 checks whether the ATC terrestrial signal is not received or the signal strength of the ATC terrestrial signal is lower than a reference (eg, an average value) (S103).

As a result of the check (S103), when the ATC ground signal is not received or the signal strength of the ATC ground signal is lower than the reference (eg, the average value) (YES in S103), the controller 130 determines the current driving position as an abnormal signal point (S104).

At this time, the inspection position indicator dropping unit 170 can be installed at either the front or rear of the electric vehicle, but is preferably installed at the rear of the electric vehicle. This is because, when the driving speed of the electric vehicle is fast, the exact location may not be displayed by determining the occurrence of the abnormal signal point and already traveling a certain distance.

After dropping (or firing) the inspection position indicator (not shown) to the abnormal signal point as described above, the control unit 130 further includes a predetermined time before and after the section determined as the abnormal signal point (view point section). The ATC terrestrial signal data (that is, raw data) corresponding to the section is transmitted to the control server 200 (S203).

Accordingly, the control server 200 analyzes the reason why the abnormal signal point has occurred (that is, the reason for the failure) so that it is possible to determine whether the vehicle (electric vehicle) is malfunctioning or the signal facility is malfunctioning.

As described above, the control server 200 receiving the first abnormal signal point information (that is, the first abnormal signal point information) stores the first abnormal signal point information (ie, the first abnormal signal point information) in the database 210 ).

At this time, in the database 210, in addition to the information transmitted from the electric vehicle (actually, the ATC ground signal autonomous inspection system mounted on the electric vehicle), the control server 200 detects (collects) itself (that is, an abnormal signal point). At the time of occurrence), the surrounding situation (ie, earthquake, weather, traffic accident, etc.) and past history (ie, the history of abnormal signal occurrence for each vehicle and branch) of the corresponding point (ie, abnormal signal point) are additionally accumulated and stored. .

For reference, the history information is information for determining whether the occurrence of the abnormal signal point (that is, occurrence of a failure) occurs frequently in a specific vehicle or frequently at a specific point, and the surrounding situation information includes the abnormal signal point This information is used to determine whether it occurs temporarily under the influence of the situation or without being affected by the surrounding situation.

When the first abnormal signal point information (that is, the first abnormal signal point information) is received (reported), the control server 200 performs a designated primary response (S302).

For example, the control server 200 may transmit a message (eg, a text message, a dedicated APP message) to the manager 300 (or the mobile terminal of the manager).

However, even if the first abnormal signal point information (that is, the first abnormal signal point information) is received, since the cause of the abnormal signal point may not be accurately determined, the control server 200 may include the additional primary response method. As, the second electric vehicle TR2 (that is, the second electric vehicle that calls the first abnormal signal point) is instructed to slow down at the reported abnormal signal point (ie, the first abnormal signal point) (S303).

Then, when the occurrence of the abnormal signal point is reported again in the second electric vehicle TR2 (that is, the second electric vehicle that calls the first abnormal signal point) (that is, when the second abnormal signal point information is received) ( S304), the control server 200, which has determined the correct cause by analyzing this, performs a designated secondary response (S305).

For example, the control server 200 includes information on the abnormal signal point (eg, time, location, image, vehicle speed, vehicle information), raw data of the ATC terrestrial signal acquired at the abnormal signal point, and control At the time when the abnormal signal point that the server 200 detects (collects) by itself is generated, the failure occurs (that is, an abnormal signal point occurs) through analysis of the surrounding situation and the history of abnormal signal generation for each vehicle or branch in the past. It is determined whether this occurred in a specific vehicle, at a specific point, or temporarily, under the influence of surrounding conditions. In addition, a message (for example, a text message or a dedicated APP message) may be transmitted to the manager 300 (or the manager's portable terminal) to perform the quick maintenance.

As described above, in the present embodiment, the ATC ground signal is detected in real time during the operation of the electric vehicle, and a location where the no signal or signal strength is detected is lower than the average is detected and transmitted to the control server by wireless communication, so that the manager predicts and prevents a facility failure. It has the effect of allowing maintenance to be carried out. In addition, this embodiment enables the safety of the electric vehicle by automatically checking the facilities in real time while the electric vehicle is driving, even if the administrator does not check the facilities (eg, rails, signal transmission means, etc.) of the section in which the electric vehicle is operated. It has the effect of improving.
