It consists of the vehicle display number, TRS number, driver's number, driver's name, etc. displayed.

Hereinafter, referring to FIGS. 12 (a) to 12 (k), a method of controlling the operation of a vehicle driving a regular regular fixed route according to the present invention will be described.

First, the control system 140a receives vehicle position information from the navigation system 300 mounted on the vehicle 110 (step: S1201).

Preferably, since the vehicle position information transmitted from the vehicle is a value obtained by removing the 'degree' values of latitude and longitude as described above, in step S1202, a reference value is added to restore such position information to the original position information.

Subsequently, the database unit 142a, which stores the station information based on the added position information, substitutes the first designated interval into the query sentence to sequentially search for data satisfying the condition, and displays the nearest station and road on the nearest approximation. Find the point.

At this time, if the condition is not satisfied, the specified interval is increased by multiples and substituted into the query again to continue searching for data satisfying the condition. If the specified number of searches is equal to or greater than that, the received data is processed in error (step S1203).

After finding the nearest approximate station and the marking point on the road, the coordinates are displayed on the screen and the distance from the vehicle ahead is calculated using the coordinate values (step: S1204).

As a result of calculating the distance to the vehicle in front of the vehicle, if it is farther than the designated vehicle distance, it branches to step 100 and lights a lamp of the corresponding color (preferably blue) indicating the speeding installed in the vehicle 110, and displays the current position of the preceding vehicle. Information to be transmitted is transmitted, and the corresponding color (preferably blue) is displayed and blinks on the vehicle model on the route diagram of the display unit 143a.

On the other hand, as a result of calculating the distance with the preceding vehicle, if the distance is closer than the designated vehicle distance, the vehicle branches to step 200 and lights a lamp of a corresponding color (preferably red) indicating the speeding mounted on the vehicle 110, and the current of the preceding vehicle. Information informing the position is transmitted, and the corresponding color (preferably red) is displayed and blinked on the vehicle model on the route diagram of the display unit 143a.

On the other hand, when other processing is requested, the following is performed.

First, if there is a vehicle that has not been transmitted for a predetermined time or more, the process branches to step 400 and the corresponding color (preferably gray) lights on the vehicle model on the route diagram of the display unit 143a and continuously blinks. Subsequently, an individual transmission prohibition command is transmitted to the rear of the vehicle.

If the descending line vehicle enters the end point, the process branches to step 500 to prohibit individual transmission of the received vehicle, transfers the vehicle model on the route map of the display unit 143a to the garage, and then switches the vehicle state to the upper side. On the other hand, when the current vehicle exists outside the end point, individual transmission is started and the vehicle model is displayed on the route diagram of the display unit 143a.

If the R / F tag signal is received, branching to step 600, if the received R / F tag signal is a unique ID of the designated vehicle and descending, record the receipt time in the database unit 142a, and prohibit individual transmission. After the vehicle model is transferred to the garage from the vehicle model on the route diagram of the display unit 143a, the vehicle state is changed to the upward direction.

If the environment setting function is selected, the process branches to step 700 to adjust the total inter-vehicle distance, adjust the inter-vehicle distance tolerance, and determine whether to send a message through the environment adjustment window illustrated in FIG. 8. It also adjusts the location information transmission period and decides whether to apply it individually.

If the dispatch setting function is selected, the process branches to step 800 to move the number of the vehicle to the desired order through the dispatch adjustment window illustrated in FIG.

If the vehicle management function is selected, the process branches to step 900 to add and delete the number of vehicles per route through the vehicle registration illustrated in FIG. 11. Preferably, when adding a vehicle, information such as a modem number, a vehicle number, a vehicle display number displayed on the vehicle model, a TRS number, a driver's number, a driver's name, etc. is added.

Finally, if the vehicle information function is selected, branching to step 1000 selects any vehicle on the route map through the individual vehicle control window illustrated in FIG. 9 to display information on the vehicle, sets the distance between the individual vehicles, and performs individual transmission. Process.

The functions supported by the system and method for controlling the operation of the vehicle running the regular regular fixed route according to the present invention as described above will be described as follows.

1) Distance designation between vehicles

In the case of a fixed route, when a vehicle runs on the route, the distance from the vehicle ahead is kept constant. In order to perform this function, the control center administrator designates the distance to be maintained between any vehicle and its preceding vehicle as shown in FIG. 8, and the vehicles having the specified vehicle distance are controlled by the control station so that the vehicle can operate while maintaining the designated vehicle distance.

Preferably, the control center administrator adjusts the distance between the vehicle of vehicle number 6340 shown in FIG. 5 and the vehicle of the next vehicle vehicle number 6343 to 1 km (km) on the vehicle designation screen as shown in FIG. If you specify 200 meters (m) through the error adjustment screen, the vehicle with the vehicle number 6343 is accelerated when the distance between the vehicle with the vehicle number 6340 and the vehicle with the next vehicle number 6343 is more than 1.2 km (km). Give the command to the control station.

On the other hand, when the distance between two vehicles has narrowed to less than 800 meters, the control station issues a command to decelerate to the next vehicle, vehicle driver 6343.

Preferably, the vehicle distance adjustment may equally set the distance between vehicles for all vehicles currently running, or may be adjusted individually.

Looking at this in more detail, the overall vehicle distance adjustment function is a function that allows all vehicles running on the route to the same vehicle distance when the designated distance is designated once on the vehicle distance designation screen as shown in FIG. 8.

On the other hand, the individual vehicle distance adjustment function designates the overall adjustment function.In this case, when each vehicle cannot maintain the designated distance according to traffic conditions and traffic conditions, it is possible to effectively use the distance from the preceding vehicle individually. It is a function to adjust.

Preferably, the information about each vehicle and the vehicle interval are selected by double-clicking the corresponding vehicle on the vehicle route map shown in FIG. 7 by using a mouse, and a window is popped up as shown in FIG. can do.

2) Completion adjustment function of dispatch time

In the case of a fixed route in a route bus, the distance from the departure to the turn is generally calculated and converted into time, and the departure interval is assigned to the vehicle before departure.

However, the road situation of the running route changes from time to time, and the vehicle cannot be exported unless the vehicle coming in on time is entered. In order to improve this, the controller of the control station can see the flow of vehicles on the screen of the control system as shown in Figs.

For example, when a vehicle with a vehicle number of 100 is sent from a garage, the vehicle is dispatched every 5 minutes when the road conditions are good, but if there is a lot of time for the incoming vehicle to reach its end point, the interval is 5 to 7 minutes. This function is to adjust the distribution interval to or above, or below.

3) Distance maintenance lamp function between vehicles

After the distance between the vehicle is over a certain distance, the controller assigns the distance to the vehicle through the distance designation function and gives the command to the vehicle to accelerate. Continue to flash the lamp, which means heavy speed, to turn off the lamp that was blinking when a certain distance was reached.

Preferably, the lamp which means overspeed is a blue lamp.

On the other hand, when the distance to the vehicle in front of the vehicle is less than a certain distance to give a command to the vehicle to decelerate, at this time, the lamp that is decelerated among the lamps mounted on the vehicle continues to flash a certain distance Turn off the lamp that was indicated when it reached.

Preferably, the lamp meaning deceleration is a red lamp.

At this time, the flashing method can be repeated as described above and flashing the designated time and the designated time flashing again after waiting for the designated time, and the lamp is turned off when maintaining a certain distance and the normal operation without turning off There is a way to light the lamp that indicates.

Referring to FIG. 5, for example, if the set distance between the vehicle No. 110 and the vehicle No. 109 is 1.2 km (km), and the tolerance is specified as 100 meters (m), the distance between the vehicle No. 110 and the vehicle No. 109 Is within 1.1 km (km), the red lamp blinks to command the vehicle of 109 and turns off the red lamp when the vehicle distance is within the range of 1.1 to 1.2 km (km). On the screen of the control system of the indication that the driving state is normal, preferably expressed in green.

4) Weekday and holiday dispatch interval selection function

In general, a vehicle that runs on a regular fixed route is sensitive to road conditions, and road conditions vary significantly between weekdays and holidays. In order to efficiently manage the vehicle operation in consideration of the characteristics of each day as described above, the present invention provides such a function when the vehicle can be selectively managed using weekdays and holidays.

For example, during the week, the regular dispatch time and the regular distance are maintained, and the traffic conditions on the roads are smooth on public holidays, so the passengers can use the vehicle without increasing annoyance even by increasing the distance between the vehicles and driving the vehicle.

Preferably, since vehicle usage on weekdays and holidays is different from each other, the number of vehicles used in the order of dispatch of the screens is defined and used when dispatching vehicles, thereby effectively coping with the increase / decrease in the number of vehicle operations occurring on weekdays or holidays.

5) Send / receive disconnection and return function when the parking lot and certain area are reached

When a vehicle is put in a garage parking lot or when you enter an area where you do not need to use a communication network, you can instruct the terminal to cut off the transmission and reception so that you do not have to pay more than necessary network fees. This function is to send a function to the terminal to resume normal transmission / reception.

6) Arrange the order of vehicle allocation when the vehicle's driving order changes during operation

If the vehicle is operating normally and the order of operation is changed according to the repair of the vehicle, it is immediately applied to the control system to arrange the order of dispatch. At this time, if the controller clicks the corresponding vehicle directly with the mouse in the dispatcher adjustment window of FIG. The driving sequence is automatically sorted.

7) Adjustment function by transmission and reception time and re-display of moving status on screen every time transmission and reception

If you set the transmission / reception period as needed without fixing the transmission / reception cycle constantly, you can send / receive the movement status of the vehicle when necessary so that you can find out the unscheduled stops and efficiently. Can manage

At this time, the control system processes the data received at every reception and displays the position movement situation directly on the route map of the screen as shown in FIG.

8) Function to display vehicle number and current driving status on vehicle display model on route map of control system screen

The display model of the vehicle on the route map of the control system can be made in various kinds according to the situation. The vehicle may be displayed in a circle, a square, a triangle, or a star shape. Preferably, the vehicle is displayed in a circle, and the vehicle number is displayed therein, so that the change of the vehicle can be seen at a glance in the route map of the control system.

At this time, the color of the model changes according to the distance between the vehicle and the vehicle.

Preferably, the color of the model can be defined according to the then state of the vehicle as blue, red, green, purple and the like.

For example, the vehicle may be displayed in green on the control system screen when the vehicle is driven at a normal interval, and displayed in blue when the vehicle is far away from the predetermined distance, and displayed in red when the vehicle is within a certain distance.

That is, each of the moving vehicles is displayed in a circle having vehicle number information on the control system and displays the current driving state information in color.

9) Forcing the distance between vehicles due to road conditions and other reasons while driving and returning when the vehicle is in a normal state.

When the distance between vehicles cannot be maintained due to road conditions and other reasons during driving, this is forcibly added to or reduced from the distance between the vehicles.

On the other hand, when the road situation is returned to its original state, it can be returned to its normal state.

For example, if four vehicles are forced to a traffic jam within the designated distance, such as 131, 115, 132, and 116 in FIG. 5, the designated vehicle distance at No. 132 at the control station is 1.2 kilometers (km) to 0.6 kilometers (km). The vehicle is designated as 1.2 km (km) to 2.0 km (km) for the 114 vehicle.

When the traffic conditions are restored, these vehicles are reduced back to individual vehicle distances.

10) Prohibit individual transmission / reception and retransmission during operation

In the case of a route vehicle that operates a fixed distance at a fixed distance, the position of the preceding vehicle is always determined in order to maintain a constant distance from the preceding vehicle. If the vehicle terminal of the preceding vehicle has a problem or a traffic accident, the tail vehicle Should maintain the distance from the preceding vehicle. In this case, the control station confirms this with the TRS, talks about the problem and orders the preceding vehicle to prohibit individual transmission / reception on the screen of the control system. Then, the tail vehicle calculates a certain distance to the preceding vehicle of the preceding vehicle and at this time, adjusts the vehicle distance adjustment function accordingly at the control station.

For example, as shown in FIG. 5, when the 110, 109, and 108 vehicles are operating while the 109 vehicle loses its transmission or a failure occurs, the 108 vehicle, which is the rear vehicle, adjusts the vehicle distance from the 110 vehicle, and thus the lead vehicle to the 108 vehicle. The station will issue an individual restraining order for the 108 vehicles.

At this time, if transmission of the 109 vehicle is restored, the 108 vehicle is further issued an individual transmission start command to maintain the interval with the 109 vehicle.

11) Display information on the LCD bulletin board mounted on the vehicle while driving

For vehicles close to or away from the operating vehicle, the controller can not only display the color of the vehicle but also display the vehicle's distance from the preceding vehicle and the station name.This command turns the display on and off randomly in the control system. / off) This can be used as part of saving the charges charged at the time of transmission.
