Description

  The present invention relates to a driving accident prevention system using a planned driving curve.

  Traditionally, trains are operated according to a planned schedule.

  In addition, an object-oriented monitoring method has been proposed that can quickly and accurately perform monitoring work for switching between different screens for the same monitoring target (train, station, traffic signal) when a command is input by a train operation command device. (See Patent Document 1 below).

Furthermore, by showing the driving curve that realizes the scheduled operation, the maximum speed required for the scheduled operation, and the arrival time to reach at the current speed, it is easy to predict early arrival and delay, and the driving can be adjusted by acceleration / deceleration A train operation support device that facilitates ensuring punctuality is proposed.

  However, actual train operation is not performed as it is, and there is a possibility that a train operation accident may occur.

  In view of the above situation, the present invention provides an operation accident prevention system using a planned operation curve that can perform an accurate train operation by monitoring an actual train operation state with a planned operation curve. Objective.

In order to achieve the above object, the present invention provides
[1] In a driving accident prevention system using a planned driving curve, a first memory storing a planned driving curve, a second memory storing an actual driving curve, and a planned driving curve from the first memory. A comparison unit that compares data and actual driving curve data from the second memory for each point, and a result of comparison between the planned driving curve data and the actual driving curve data by the comparing unit. A notification device for notifying a driver when a deviation between the data and the actual driving curve data is equal to or greater than a predetermined threshold value for each point is provided.

  [2] In the driving accident prevention system using the planned driving curve described in [1], the notification mode of the notification device is changed depending on the degree of deviation between the planned driving curve data and the actual driving curve data. And

  According to the present invention, an accurate train operation can be performed by monitoring an actual train operation state with a planned operation curve.

  Further, by operating according to the driving accident prevention system using the planned driving curve, the driver's tension is low and safe driving can be carried out.

  A driving accident prevention system using a planned driving curve according to the present invention includes a first memory for storing a planned driving curve, a second memory for storing an actual driving curve, and a planned driving curve from the first memory. A comparison unit that compares data and actual driving curve data from the second memory for each point, and a result of comparison between the planned driving curve data and the actual driving curve data by the comparing unit. When the deviation between the data and the actual driving curve data is greater than or equal to a predetermined threshold value for each point, a notification device is provided that notifies the driver.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a block diagram of a driving accident prevention system using a planned driving curve showing an embodiment of the present invention.

  In this figure, 1 is a speedometer provided in a railway vehicle, 2 is an input device for inputting a planned operation curve, 3 is an electronic control device, and this electronic control device 3 includes an input interface 4 and a CPU (central processing unit). ) 5, timing device 6, memory 7, comparison unit 8, and output interface 9. 10 is an operation display / recording device, and 11 is a notification device (alarm, blinking indicator light, etc.).

  Here, the memory 7 includes a first memory 7A for storing planned operation curve data and a first memory 7B for storing actual operation curve data.

  Since it comprised in this way, the speed of a railway vehicle is taken in into the electronic control apparatus 3, is time-measured, the speed of a railway vehicle is measured for every distance, and is recorded on the memory 7. FIG. On the other hand, the planned operation curve is input from the input device 2 to the electronic control device 3 and recorded in the memory 7.

  Therefore, the comparison section 8 compares the planned driving curve recorded in the memory 7 with the speed of the railway vehicle recorded for each distance. As a result of the comparison, when a deviation degree equal to or greater than a predetermined threshold is found in a predetermined section, the notification device 11 notifies the driver. For example, when the speed deviates from about 7% to about 17%, an alarm or flashing light is operated to notify the driver. Here, for example, the threshold is 7%.

  Furthermore, the degree of danger can be estimated based on the degree of deviation described above, and an alarm can be issued accordingly. For example, when the planned operation curve data and the actual operation curve data have a deviation of 7 to 9%, it is only necessary to turn on the blinking lamp, and the planned operation curve data and the actual operation curve data are 10 to 17 When the deviation is%, the blinking lamp can be turned on and the alarm sound can be generated simultaneously.

  FIG. 2 is an example showing a planned operation curve and an actual operation curve according to the present invention, in which the horizontal axis indicates kilometer (km) and the vertical axis indicates train speed (km / h).

  As is apparent from this figure, it can be seen that the actual operation curve B deviates from the planned operation curve A in the range of 1.0 to 1.6 km in kilometer.

  When such a deviation degree is found, an alarm or a flashing light is driven to notify the driver.

  FIG. 3 is a graph showing data analyzing the relationship between the driving margin (delayed early arrival time with respect to the planned driving time between stations) and the driver's tension, and the horizontal axis shows the delayed arrival time (seconds). Is the heart rate against rest (%) on the vertical axis [shows that the upper is a high degree of tension and the lower is a low degree of tension. r is a correlation coefficient.

  From this figure, it can be seen that as the actual driving time becomes shorter, the tension shown in the heart rate increases, so from this, the driver's tension becomes higher or lower as it deviates from the planned driving curve. Therefore, by using the driving accident prevention system using the planned operation curve of the present invention and enforcing the planned operation curve, the driver can perform safe operation with an appropriate degree of tension.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

  The driving accident prevention system using the planned driving curve of the present invention can maintain an appropriate degree of tension of the driver, and can be used as a driving accident prevention system that performs safe operation.

It is a driving accident prevention system block diagram using a planned operation curve showing an embodiment of the present invention. It is an example which shows the plan operation curve concerning this invention, and an actual operation curve. It is a figure which shows the data which analyzed the relationship between a driving margin (the delay early arrival time between stations) and the tension degree of a driver.
