Emergency notification system for vehicle protection {AN EMERGENCY COMMUNICATION SYSTEM FOR PROTECTION OF A VEHICLE}

The present invention relates to an emergency notification system for protection of a vehicle for transmitting an accident signal of a vehicle to prevent an accident, and more particularly, when an accident occurs during operation of the vehicle, The present invention relates to an emergency notification system for protecting a vehicle for transmitting an accident signal through a relay device and transmitting the accident signal through a receiving device, thereby transmitting a protection signal for preventing a second continuous accident.

As modern society has been civilized and highly developed, the types of vehicles that carry humans have diversified and become widely available. In particular, vehicles that transport more people at the same time in a fast and accurate time, such as in the subway, crowded cities play a role as people's favorite public transportation.

While these vehicles carry a large number of people at a fast and accurate time, many people are injured once an accident occurs in a running vehicle, especially since subways run on a constant track, A series of crashes can cause more people to be injured or even lose their precious lives.

Therefore, when an accident occurs in a vehicle in operation and an accident in which the operation is stopped, such a situation should be promptly informed to the vehicle in operation to prevent the accident from spreading in series. Generally, for this purpose, when an accident occurrence button is pressed or a contact signal operating when an error occurs is input to the protection signal transmission device of the accident vehicle, the signal is converted into a simple alarm signal notifying the accident and transmitted, and the alarm signal is transmitted. A system of how to detect an accident and brake the vehicle when a subsequent vehicle is received is being used.

However, this method has the following problems in view of the characteristics of radio waves and railway operation.

Due to the nature of radio waves, the area where wireless communication is performed is very dependent on the environment such as the surrounding terrain. Therefore, the accident signal is very limited in the distance, such as tunnels, mountain areas, the immediate reception of the accident signal from the adjacent vehicle may not be. Conversely, if the radio waves are transmitted too far, there may be a situation where the vehicle is stopped without the need for a vehicle having a safety distance that does not necessarily stop.

Vehicles moving away from the accident vehicle do not have to stop and may continue. However, in the system that transmits only a simple accident, it is not possible to determine whether it is possible to proceed with the vehicle that has received this information.

Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to use an emergency notification system for protection of a vehicle including navigation means, when an accident occurs, not an accident signal indicating that a simple accident has occurred. In addition, by transmitting accident information including the location of the accident, the vehicle receiving the signal determines whether the vehicle is approaching or deviating from the accident point, and prevents braking or stopping of the vehicle that does not require braking. It is to provide an emergency notification system for protecting a vehicle to promote safe and efficient operation of the vehicle.

Another object of the present invention is to provide an emergency notification system for the protection of vehicles to solve the shadow area where radio waves cannot reach and to improve the efficiency of radio wave transmission by enabling the relay of accident signals transmitted from an accident vehicle using a single frequency. To provide.

Referring to Figure 1, the overall emergency notification system 10 according to the present invention is composed of a terminal 100, a repeater 200 and a terminal 100 ', or a terminal 100 and a terminal 100'. However, the repeater 200 is a device for receiving and retransmitting and relaying accident information transmitted from an accident vehicle in a shaded area where direct communication between the terminal 100 and the terminal 100 'is difficult, and receiving the accident information. 100 'receives the accident information transmitted from the accident vehicle or retransmitted by the repeater 200.

First, the detailed configuration of the terminal is as shown in FIG.

Navigation means 120, for example, GPS is a commercially available device, and performs the function of detecting the current position, direction, and speed information of the current vehicle through the control means 110.

Temporary storage means 113 temporarily stores the data consisting of the previous position and the current position of the vehicle by the navigation means 120, because such data is changed from time to time as the vehicle moves the navigation means 120 The position data is changed from time to time, and the position data is called by the control means 110 as an element of the accident information in a vehicle accident and is transmitted as part of the transmission data.

The main storage unit 130 of the terminal 100 is a read-only memory such as a ROM, and stores a unique number and route data of the vehicle, and the unique number of the vehicle stored in the main storage unit 130 is described above. The accident information is formed together with the accident location data of the vehicle from the temporary storage means 113 and transmitted.

The wireless transmitter 117 transmits accident information to prevent another accident by warning other vehicles in case of an accident of the vehicle in operation, and, conversely, the radio receiver 119 at the time of an accident of the other vehicle, It serves to receive accident information from the vehicle.

The accident detecting means 129 detects an accident signal of the vehicle itself, and detects a signal generated by injecting the accident input button 125 when the driver recognizes an accident or detects an accident part by detecting an accident part. 127 is detected and automatically inputs a signal to detect an accident.

The control means 110 includes a central processing unit 111, when receiving the accident information from the counterpart vehicle, analyzes the received accident information to determine whether the vehicle is braking, and during the vehicle accident, the main memory means ( Incident information consisting of the unique number of the vehicle stored in 130 and the accident location data of the vehicle from the temporary storage means 113 is transmitted. At this time, the control means 110 is provided with a transmission pause time setting means 115 for setting the time for transmitting the accident information.

The transmission pause time setting unit 115 transmits the accident information again after a predetermined time after the transmission of the accident information, so that the repeater 200 to be described below may retransmit the accident information again. Set an idle time for the time interval, so that the repeater transmits the accident information at the same frequency.

Alternatively, the control unit 110 controls the terminal to operate as a repeater when receiving accident information from the other vehicle, but analyzes the received accident information to determine whether the vehicle is braking, the vehicle is near the accident point and the accident When the current separation distance to the point is within a certain distance, the braking device 123 is controlled to brake the vehicle, in the event of a vehicle accident, the terminal 100 transmits the accident information of its own vehicle to another vehicle, the accident information Control to retransmit relay again.

In addition, the display means 121 for displaying the contents of the accident information may be included in the terminal 100 of the vehicle.

Next, the configuration of the repeater 200 will be described with reference to FIG.

The repeater includes radio transmitters and receivers 217 and 219, main storage means 230 and temporary storage means 213, control means 210, idle time setting means 215, and the like.

The radio transmitter 217 retransmits the accident information for relay, and the radio receiver 219 receives the accident information from the radio transmitter 117 of the terminal.

The main storage unit 230 stores its own information data of the repeater consisting of the unique number of the repeater 200 and the installation location data, and the temporary storage unit 213 is received through the radio receiver 219 of the repeater 200. The accident information that is to be stored and the unique information of the repeater 200, or the accident information for the relay consisting of the unique information and the installation location data of the accident information and the repeater 200 temporarily.

The control means 210 determines and relays whether or not relaying accident information is relayed, and transmits the relaying accident information from the wireless transmitter 117 of the terminal 100 during an idle time to stop the terminal at one frequency. The transmitter 117 of the transmitter 100 and the transmitter 217 of the repeater are provided with a relay idle time setting means 215 for setting the idle time for retransmission during the idle time which is not the same.

The control unit 210 controls the repeater not to retransmit the accident information when the accident point is not within a certain distance from the repeater 200.

Next, the operation and effects of the present invention constructed as described above will be described.

The entire emergency notification system 10 transmits an accident signal from the terminal 100 in which the accident occurred, and the repeater 200 and the neighboring terminal 100 receive the accident information and, if necessary, brake the vehicle by the information. Or the whole operation is performed in the order of relaying. Here, the detailed operation of each device is expressed as follows.

Referring to the flow chart of Figure 6, the method of transmitting accident information when a train accident occurs (S101-S108), when an accident occurs in the train, the engine driver, etc., if the driver recognizes the accident by pressing the accident input button 125, When the situation is input or there are other sensors in the train, the contact signal output from the device is received by the accident contact input unit 127 and the accident detection means 129 detects the accident occurrence state in the control means 110. Done.

When the accident is recognized in the control means 110, the control means 110 generates an accident information consisting of the vehicle unique number and the accident occurrence position data of the vehicle. Based on this, the radio transmitter 117 calculates the time required to transmit data, sets the transmission pause time, and sets the time for transmitting the accident information and the pause time.

The radio transmitter 117 is controlled by the control means 110 to transmit the accident information in the form of radio waves, and waits in a reception state again to receive the accident information. The control means 110 uses the idle time, and when the first data transmission time (Fig. 4 'transmission 1') and the idle time ('pause 1-1' and 'pause 1-2') elapse, the same accident again Control to transmit information via the wireless transmitter 117. This process is repeated periodically as shown in FIG. In the example of Fig. 4, the case of the transmission and the pause is 1: 2, and the transmission and the pause time may be 1: 1 or any other ratio.

In another embodiment, when the control means 110 transmits only the accident information and the 'transmission pause ratio', the wireless transmitter 117 uses a timer and a storage device (not shown) inside the wireless transmitter 117. In addition, the message transmission and pause can be repeated. This case is very similar to the above-described embodiment, and can be easily implemented using the foregoing embodiment, and thus will not be described in detail.

Referring to Figure 8, below, the accident information relay process of the repeater 200 will be described.

When the accident information is received by the radio receiver 219 of the repeater 200, the control unit 210 detects the accident occurrence position in the accident information and installs the repeater 200 stored in the main memory 230. Calculate the distance difference between the location and the accident location. If this distance difference is within a certain distance, the repeater's unique number or unique number and installation location is added to the accident information to generate the accident information for the relay and retransmitted, and if there is more than a certain distance, there is no need for a relay, Keep receiving.

As described above, if the distance between the accident location and the repeater is a certain distance, retransmit the accident information for the relay, as shown in Figure 4, avoiding the accident information transmission time of the accident vehicle idle 1-1 or pause An accident signal should be sent at the time of 2-1. 4, the accident information directly transmitted by the terminal 100 of the accident vehicle and the accident information retransmitted by the repeater are separated in time, thereby enabling radio wave transmission and relay functions without interference. At this time, if necessary, a marker indicating that the accident signal is relayed may be added to the relay 200 transmission signal.

The reception operation of the terminal 100 will be described with reference to FIGS. 2 and 9.

The radio receiver 119 of the terminal 100 of the general vehicle in which an accident does not occur receives an accident signal transmitted directly from the accident vehicle or retransmitted by the repeater 200 or both, and the control means 110 receives this information. Will be recognized.

The control unit 110 calculates whether the accident has spread by using the accident information received from the radio receiver 119. If necessary, the display device is controlled to display an accident signal and an accident area, and an accident contact is output to generate an alarm to brake the train. Detailed implementation embodiments are as follows.

The 'accident location' is extracted from the received accident information, and its 'current location' and 'previous location' are obtained through the temporary memory device 113 of the terminal, and the 'current distance' from the accident location is If the value is smaller than the previous distance, it is determined that the accident area is approaching. If the value of the current distance is within a certain distance, an alarm and / or an accident signal is displayed. On the contrary, if the value of 'current separation distance' is greater than 'previous separation distance', it is determined that the accident area is leaving, and an alarm and / or an accident signal is displayed when necessary.

When the value of the calculated 'current separation distance' is within a certain distance and approaches the accident point, the vehicle is braked through the brake device 123 under the control of the control means 110, and optionally, mounted on the vehicle. The terminal 100 may retransmit the accident information by using the downtime of the received accident information.

At this time, when the transmission time zone and the repeater of the received accident vehicle are in operation, the accident signal is retransmitted by avoiding the radio wave transmission time of other devices through the idle time as shown in FIG.

Referring to FIG. 9, when the test operation of the repeater 200 is described, the terminal 100 includes the installation location information of the repeater in the route database for the test of the repeater, and transmits the test accident information using the location information. Then, by receiving the accident signal retransmission signal of the repeater, it is determined whether the repeater is in normal operation. Detailed embodiments are as follows.

First, the terminal 100 generates test accident information, and the control means 110 of the terminal compares the current position data with previously stored repeater installation position data to determine whether the distance between the current position of the vehicle and the repeater is within a certain distance. To judge.

If the distance from the repeater 200 in the control means 110 of the terminal within a certain distance transmits the accident information for testing using the wireless transmitter 117, when receiving the accident information from the wireless receiver 219 of the repeater, The means controls the radio transmitter to retransmit this accident information,

If the terminal 100 does not receive this signal within a certain time, it is determined that the repeater 200 is operating abnormally.

As described above, the present invention transmits and receives an accident signal including location data when an accident occurs in the operation of a vehicle such as a train, so as to automatically determine whether it is adjacent to the accident area and whether it is approached or not. This is to prevent the spread of vehicle accidents, to improve the driving efficiency, and to solve the shadow area using a relay device for safety. At this time, it is effective to increase the use efficiency of radio waves by preventing the collision and interference of the retransmitted signal by relaying with the original signal while using a single frequency.
