Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The apparatus of the present invention collects and provides traffic information through DSRC communication as shown in FIG. 2, and allocates the vehicle 1 equipped with an OBE terminal for it and specific equipment for collecting and managing traffic information of the vehicles. Traffic control center (2) which controls the reset function of the corresponding equipment by controlling the reset function of the corresponding equipment by transmitting an encrypted signal when the hook-off signal from the corresponding equipment is transmitted by transmitting the original unique number (Dial Number) (2) And, when the vehicles 1 approaches within the cell radius, traffic information is collected or provided through DSRC communication using the OBE terminal and the use frequency of the approached vehicle 1, for example, a frequency of 5.8 GHz band. The roadside base station 3 which is installed on the roadside and resets the equipment according to the reset control signal of the upper level equipment, and the traffic information or the downlink signals collected from the roadside base stations 3 Modulation and demodulation and the traffic control center (2) consists of a fire station base distribution box (4) for resetting the corresponding equipment to analyze the unique telephone number and the password signal transmitted through the communication network for the equipment reset.

In addition, the roadside base station distribution box 4 detects the ring signal transmitted according to the unique telephone number signal of the traffic control center 2, transmits a hook-off signal in response thereto, and then analyzes the received reset password signal. The telephone receiver unit 5 for controlling the reset function of the equipment and the communication signal transmitted and received between the traffic control center 2 and the roadside base station 3 are modulated and demodulated and processed. The modem 6 which performs a reset function according to a reset control signal is provided.

Here, the signal transmitted and received between the roadside base station distribution box (4) and the traffic control center (2) is a DSLAM (8) and exchanger (9) and Internet dedicated network (10) provided in the main communication network, for example, the telephone station (7) It is transmitted through the telephone network 11 or the like.

Next, the control method of the present invention as described above will be described.

The present invention proceeds from the initialization step (S1) to the traffic information processing step (S2), as shown in FIG. 3, the traffic control center collects and analyzes traffic information from each roadside base station through a communication network, and transmits the result to the corresponding service subscriber. to provide.

That is, when the vehicle 1 equipped with the OBE terminal approaches the roadside base station 3, the corresponding roadside station 3 provides real-time public transportation information such as route information, transfer information, public transportation guidance, and arrival time guidance. Collect it through the DSRC and transmit it to the firebox base distribution box (4). Then, the modem 6 of the roadside base station distribution box 4 modulates the received public transportation information and transmits it to the traffic control center 2 through the DSLAM 8 of the telephone station 7 and the Internet exclusive network 10.

Accordingly, the traffic control center 2 analyzes and provides the public traffic information collected from the plurality of base station distribution boxes 4 to the user.                     

In this case, when it is necessary to transmit a signal from the traffic control center 2 to the vehicle 1 equipped with the OBE terminal, the signal is processed through the above process and the reverse process.

On the other hand, after the traffic information processing step (S2) proceeds to the roadside station failure determination step (S3) to ping-test a specific roadside base station suspected of the failure. And, during the roadside station failure determination step (S3) If the result of ping-testing a specific roadside base station suspected of occurrence is confirmed that the roadside base station has failed, proceed to the communication call connection step (S4), and the unique telephone number as a roadside base station distribution box managing the roadside base station in the traffic control center. The caller makes a call and the corresponding firebox distribution box emits a ringing tone in response. In addition, after the communication call connection step (S4) proceeds to the encryption reset signal processing step (S5) and transmits the reset signal of the roadside base station encrypted in the traffic control center and the received roadside station distribution box decrypted the cipher and the pre-stored password If it matches with, it sends a reset control signal to the corresponding roadside base station. However, during the encryption reset signal processing step S5, the roadside base station distribution box hooks up the system again if the received signal does not match the previously stored password. On the other hand, after the encryption reset signal processing step (S5) proceeds to the faulted roadside base station reset step (S6), the faulted roadside base station resets the base station according to the reset control signal of the roadside base station distribution box.

On the other hand, if the ping test of the particular base station that is suspected of failure in the failure of the base station failure determination step (S3) is confirmed that the failure of the corresponding base station proceeds to the base station modem failure determination step (S7). Ping-test the modem of the roadside base station distribution box suspected of a failure. Then, during the base station modem failure determination step (S7), ping-test the modem of the particular roadside station distribution box suspected of a failure, and the modem fails. If not, the process returns to the traffic information processing step S2 to repeat the loop. However, if a failure occurs in the modem of the base station distribution box suspected of failure during the base station modem failure determination step (S7), the modem proceeds to the modem communication call connection step (S8) to control traffic. The center makes a call through its own telephone number signal to the corresponding firebase station distributor and the firebox distribution box sends a ringing tone in response. In addition, after the modem communication call connection step (S8), the modem encryption reset signal processing step (S9) proceeds to transmit the reset signal of the roadside base station encrypted at the traffic control center, and the received roadside station distribution box decrypts the cipher. If the password matches, the reset signal is sent to the corresponding modem. However, during the modem encryption reset signal processing step S9, the roadside base station distribution box hooks up the system again if the received signal does not match the previously stored password. On the other hand, after the modem encryption reset signal processing step (S9) and proceeds to the faulty modem reset step (S10), the modem having a failure occurs to reset the modem in accordance with the reset control signal of the fire station base distribution box.

In other words, the traffic control center 2 analyzes the public transportation information collected from the plurality of base station distribution boxes 4 and provides the user with the modem 6 or the roadside base station of some roadside base distribution boxes 4. 3) In the event of a failure, that is, a HALT condition, the traffic control center 2 transmits a ping signal to the modem 6 and the roadside base station 3 of the roadside base station distribution box 4 which is suspected to have a failure and executes a ping test. Here, if the traffic control center 2 detects an abnormality during the ping test process, the traffic control center 2 calls the unique telephone number of the corresponding firebox base distribution box 4 through the telephone network 11 and the telephone station 7. Then, when the ring signal transmitted from the traffic control center 2 is detected, the telephone receiver unit 5 of the roadside base station distribution box 4 detects a hook-off signal, that is, a ringing tone transmitted to the calling party. Transfer to the traffic control center (2) through. At this time, the traffic control center (2) is a cipher reset signal for instructing the reset of the particular fire station if the current equipment to be reset as a result of the ping test, for example, DTMF Digit: * 1234 in the form of the corresponding fire station The telephone receiver unit 5 of the distribution box 4 is transmitted. Then, the telephone receiver unit 5 of the roadside base station distribution box 4 decrypts an encrypted reset signal received from the current traffic control center 2, for example, a signal such as DTMF Digit: * 1234 and decrypted the decrypted signal. Search for the signal in the list of specific pre-stored base stations (i.e., execute a Security Check). At this time, the telephone receiver unit 5 of the corresponding roadside base station distribution box 4 is the case that the decrypted signal is not included in the list of the stored specific roadside station, for example, if the received password is different from the previously stored encryption signal Hook on the system.

However, if the decrypted signal is included in a list of stored specific firebase stations, the telephone receiver unit 5 of the corresponding firebase station distribution box 4 may receive, for example, a received cipher from the stored cipher signal. In this case, the reset control signal is sent to the corresponding roadside base station 3. Then, the roadside base station 3 resets the roadside base station 3 according to the reset control signal input from the telephone receiver unit 5 of the roadside base station distribution box 4, and executes the normal communication state again.                     

On the other hand, the traffic control center (2) if the equipment to be reset as a result of the ping test is the modem (6) of the specific base station distribution box (4) command to reset the modem (6) of the particular road base station distribution box (4). An encrypted reset signal, for example, DTMF Digit: # 1234, is transmitted to the telephone receiver unit 5 of the corresponding roadside base station distribution box 4. Then, the telephone receiver 5 of the roadside base station distribution box 4 decrypts an encrypted reset signal received from the current traffic control center 2, for example, a signal such as DTMF Digit: # 1234 and decrypted the decrypted signal. Search for the signal in the list of specific pre-stored modems (ie run a Security Check). At this time, the telephone receiver unit 5 of the roadside base station distribution box 4, if the decrypted signal is not included in the list of the stored specific modem, for example, if the received password is different from the pre-stored encryption signal system Hook on.

However, the telephone receiver unit 5 of the corresponding base station distribution box 4 is the case that the decrypted signal is included in the list of the specific modem stored in advance, for example, if there is a received password matches the previously stored encryption signal. The reset control signal is sent to the modem 6. Then, the modem 6 resets the modem 6 according to the reset control signal input from the telephone receiver unit 5 of the fireside base station distribution box 4, and executes the normal communication state again.

As described above, the present invention includes a telephone receiver unit having a unique telephone number and an encryption function in a firefighting base station distribution box, and when a reset of the fireside base station is required, the remote control is performed by the remote control center to control the fireside base station. There is no need for the administrator to go through the reset manually in order to reset according to the failure of the system, which has the advantage of significantly reducing the maintenance cost of the base station.

In addition, according to the present invention, since the control center immediately detects the failure of the fire station base station or the fire station base station switchboard modem, and automatically resets remotely through the telephone number, it is possible to quickly maintain the fire station base station, thereby maintaining good communication quality. There is also an effect.
