Description

  The present invention relates to an improvement of an operation management device.

  An operation status storage device that generates operation history data includes an in-vehicle camera installed in a vehicle, an acceleration sensor that detects acceleration of the vehicle, and a storage unit that constantly stores an image captured by the in-vehicle camera, and acceleration is dangerous. When a threshold value that is a level is continuously exceeded for a certain time or longer, this is set as a condition (trigger), and the image stored in the storage means is read and the image data before and after the trigger detection is recorded in the storage medium. (For example, refer to Patent Document 1).

  That is, the storage medium includes image group data including image data captured by the in-vehicle camera when the acceleration acting on the vehicle reaches a danger level, travel data indicating the travel state of the vehicle associated with the image group data, and travel The operation history data including the position data is recorded, and the operation history data is recorded as many times as the number of times the above condition is satisfied.

  In addition, by setting the threshold, which is a danger level, to an acceleration value that is detected when braking suddenly before excessive speed is reached or an accident does not occur, the operation history data can be stored at a time other than when a vehicle accident occurs. In addition, it is generated even in a driving situation where the driver gets tired or disappointed during driving, that is, a so-called near-miss.

On the other hand, the operation management device includes, for example, a reading unit that reads out the operation history data from a storage medium in which the operation history data is recorded, a storage unit that stores the read operation history data, and the operation history data. Display means for reproducing and displaying the image group data (see, for example, Patent Document 2). In particular, the operation history data of the operation history data by a company operating a business such as a taxi, a bus, or a railroad. It is often used for reference and analysis purposes, and its main purpose is to support operation management work.
Japanese Patent Laying-Open No. 2005-165805 (paragraph numbers 0020 to 0033, FIG. 1) Japanese Unexamined Patent Publication No. 2000-171267 (FIG. 11)

  The operation management device is mainly intended to facilitate operation management work by an operation management worker, but as described above, operation history data is accumulated daily in the storage means of the operation management device. .

  And since this operation history data is generated not only when an accident occurs but also when a near-miss occurs, it is not only useful for operation management workers, but also useful for vehicle drivers. It is preferable that the person also refers to the operation management data stored in the operation management device.

  In particular, in business organizations that operate businesses such as taxis, it is desirable to instruct vehicle drivers so that operation history data is not generated, in which case many vehicle drivers are gathered. It is efficient to train, and in such training, referring to the image data included in the operation history data, explain the situation that the operation history data has been generated, and such operation history It is also preferable in terms of learning effect to instruct to improve driving so that data is not generated.

  However, when conducting training, there is no problem as long as the operation management worker is good at operation of the operation management device, but in many cases the instructor is not the same person as the operation management operator, so that the instructor also It is necessary to be familiar with operation of the operation management device, which increases the burden on the instructor, makes it inefficient to make the instructor in charge of the operation of the operation management device, and also instructs the instructor in trouble. It becomes work.

  Therefore, the present invention was devised to improve the above-described problems, and the object of the present invention is an operation management device that can easily train using operation history data without being familiar with the operation. Is to provide.

  The operation management device in the problem solving means of the present invention includes image group data including image data captured by an in-vehicle camera when travel data indicating a travel state of a vehicle reaches a danger level, and travel data associated with the image group data. A reading means for reading out the operation history data from a storage medium in which the operation history data including the driving position data is recorded, a storage means for storing the read operation history data, and reproducing image group data included in the operation history data Display means, and character display means for temporarily stopping image group data reproduction and displaying previously registered character information.

  According to the operation management device of the present invention, not only for operation management, but also for training, training preparation and training execution can be performed without imposing a burden on the instructor in charge of the training. Therefore, the training using the operation history data can be easily performed without being familiar with the operation of the operation management device.

  Furthermore, the operation management device is suitable not only for training for a large number of people but also for referencing the operation history data without being familiar with the operation, so that the vehicle driver can individually refer to the operation history data. It is also possible to use it for guidance.

  The present invention will be described below based on the embodiments shown in the drawings. FIG. 1 is a diagram illustrating a system configuration of an operation management apparatus according to an embodiment. FIG. 2 is a diagram showing a system configuration of a drive recorder that generates operation history data and records it on a storage medium. FIG. 3 is a diagram showing a display screen of the display means in a state where the reproduction of the image group data is paused.

  The operation management device 1 stores programs such as a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory) that provides a storage area for the CPU, and an application and an operating system executed by the CPU. It is realized by a known computer system that includes a storage device such as a hard disk and operates by a control program such as a BIOS or an operating system.

  As shown in FIG. 1, the operation management apparatus 1 includes a data reading unit 2 that holds a storage medium 10 on which operation history data is recorded and can read operation history data from the storage medium 10. A display device 3 for displaying a screen necessary for handling operation history data and a reproduction screen for image group data included in the operation history data, and an input device 4 enabling input of data necessary for handling operation management data. A data processing unit 5 that is realized by the CPU executing an application program and a control program for operation management, a reproduction unit 6 that reproduces image group data included in the operation history data, operation history data, and Storage unit 7 for storing various programs, setting editing unit 8 for performing various settings and editing, and input / output for controlling data input / output between these units It is constituted by a control unit 9.

  On the other hand, the operation history data recorded in the storage medium 10 is generated by the drive recorder 11 mounted on the vehicle to be managed by the operation management apparatus 1 and recorded in the storage medium 10.

  As shown in FIG. 2, the drive recorder 11 includes an in-vehicle camera 12 installed in the vehicle, an acceleration detection unit 13 that detects acceleration acting on the vehicle, a speed detection unit 14 that detects a traveling speed of the vehicle, A storage device that always stores image data captured by the GPS receiver 15 and the in-vehicle camera 12 and acceleration data, speed data, date and time, and travel position data of the latitude and longitude of the vehicle in association with the image data. 16, a holding unit 17 that holds the storage medium 10 and can read and write data from the storage medium 10, and a control unit 18. In particular, the driving data used for determining the danger level is acceleration in this case.

  In the drive recorder 11, it is determined whether or not the acceleration detected by the control unit 18 has reached a dangerous level. When the acceleration stored in the storage device 16 has reached the dangerous level, the on-vehicle camera 12 extracts image group data including image data captured by the image 12 and acceleration data, speed data, date / time, and travel position data, which are travel data indicating the travel state of the vehicle associated with the image group data. One operation history data is generated, and this operation history data is recorded in the storage medium 10 via the holding unit 17.

  The control unit 18 captures an image captured by the always-on-vehicle camera 12 as a moving image, cuts out a still image from the moving image at a predetermined frame rate, and converts the still image into a predetermined compression format such as JPEG or GIF. The image data of the compression format is generated. If the frame rate is increased too much, the volume of image data generated per second becomes too large and a large-capacity storage device is required, so that there is insufficient image data for verification at the time of a vehicle accident. For example, it is set to about 5 to 10 frames per second.

  The image group data included in the operation history data is a set of image data captured by the in-vehicle camera 12 within a predetermined range before and after the acceleration reaches a danger level. For example, about 10 seconds before and 20 seconds after the acceleration reaches the danger level, the total is about 30 seconds.

  The acceleration detection means 13 basically detects the front / rear / left / right biaxial acceleration of the vehicle, and the controller 18 selects either the absolute value of the longitudinal acceleration or the absolute value of the lateral acceleration. When the value exceeds the threshold value set corresponding to each, it is determined that the acceleration has reached the danger level. The threshold value is set to the acceleration value that will be detected during a near-miss, and The history data is generated and recorded in the storage medium 10 not only when an accident occurs but also when a near-miss occurs.

  Returning back, each part of the operation management device 1 will be described in detail. The data reading unit 2 can adopt a unit suitable for the format of the storage medium 10. For example, the storage medium 10 is used for data transfer in a card format. In the case where the card is received and held, the terminal connected to the terminal of the storage medium 10 may be provided, and the storage medium 10 may be a CD-ROM or DVD. In the case of an optical disk, the data reading unit 2 may be a disk drive device that accommodates the optical disk inside and accesses the optical disk to read and write data.

  As the display device 3, for example, an LCD (Liquid Crystal Display), electroluminescence, CRT (Cathode Ray Tube) or the like may be used.

  The data processing unit 5 reads the operation history data recorded in the storage medium 10, statistically processes the operation history data, and reads the frequency analysis unit 51 that calculates the frequency of the travel position from which the operation history data was collected. It comprises a classification storage unit 52 that stores operation history data collected at a frequently traveled position in the operation history data in a training folder 71 created in the storage unit 7, and a risk judgment unit 53. . The classification storage unit 52 stores the operation history data collected at the less frequent driving position in the normal management folder 72 and also manages the operation history data stored in the training folder 71. The folder 72 is also stored for operation management.

  Specifically, the frequency analysis unit 51 extracts the vehicle travel position data from the operation history data, and the travel position is obtained from statistics of the operation history data collected in the management folder 72 of the storage unit 7 in the past. The frequency (number of times) of the travel position from which the operation history data is collected is obtained, and when the frequency (number of times) of the travel position is equal to or greater than a predetermined threshold, the travel position from which the operation history data is collected is a dangerous area. It is judged that. Basically, the travel position data used by the frequency analysis unit 51 may be the travel position when the acceleration reaches the danger level, but as described above, the travel history data includes the travel state of about 30 seconds and the like. This is a set of image group data. When the vehicle continues to travel, the travel position data changes every 30 seconds. However, the travel position data for 30 seconds may be statistically processed.

  The processing by the frequency analysis unit 51 is executed for each operation history data, updates the frequency (number of times) of the travel position, and causes the storage unit 7 to store the frequency data of the travel position separately as data for frequency analysis. . As for the recognition of the travel position, strictly speaking, the position where the latitude and longitude completely coincide may be recognized as the same position, but it is compared with the map data partitioned into a predetermined area range. If they are within the same area range, they may be treated as the same travel position.

  Subsequently, the classification storage unit 52 duplicates two pieces of operation history data collected at the travel position determined by the frequency analysis unit 51 to be a dangerous area, and one is a training folder to be used for training purposes. The other is stored in the management folder 72 to be used for operation management. When the frequency analysis unit 51 does not determine that the area is a dangerous area, the operation history data is stored only in the management folder 72.

  In addition to the above, the classification storage unit 52 uses one of the training history data for which the risk determination unit 53 has determined that the driving state of the vehicle is dangerous. The data is stored in the training folder 71 for use, and the other is stored in the management folder 72 for use in operation management.

  The danger judging unit 53 judges that the running state is dangerous when the acceleration, which is the running data in the operation history data, exceeds the danger level by a predetermined amount. The predetermined amount is set by a setting editing unit 8 to be described later, and the operation management worker can input the value from the input device 4 and edit it.

  Furthermore, the reproduction unit 6 reads the image group data included in the operation history data stored in the training folder 71 and the management folder 72 so that the display device 3 can reproduce and display the image group data. The reproduction unit 6 includes a pause processing unit 61 and a character display unit 62. Therefore, the display means in the operation management device 1 according to the present embodiment includes the display device 3 and the reproduction unit 6.

  In particular, when reproducing the image group data in the training folder 71, as shown in FIG. 3, the pause button 31 is placed at an arbitrary position that does not interfere with the image display area 34 on the screen of the display device 3. When the pause button is pressed by a click operation of the mouse 41 provided in the input device 4, the process in the pause processing unit 61 is executed, and the reproduction of the image group data is paused.

  Note that an input of a pause execution command may be assigned to an arbitrary key provided on the keyboard 42 of the input device 4, and the pause may be executed by pressing the key.

Furthermore, if the timing for pausing is associated with image data in advance, playback can be paused automatically. This association can be set by a setting editing unit 8 described later.

  When the pause processing in the pause processing unit 61 is executed, subsequently, as shown in FIG. 3, the character display area 35 where the character display unit 62 is set at an arbitrary position on the screen A of the display device 3. The character information registered in advance is displayed. That is, the character display means is composed of the one stop processing unit 61 and the character display unit 62. The character information is registered by the setting editing unit 8 and stored in the storage unit 7. The character display unit 62 reads the character information stored in the storage unit 7 and displays the character information on the screen of the display device 3. Is displayed. The character information is composed of characters and symbols or their strings. Specifically, questions suitable for images that are displayed after being paused and stationary at the time of guidance or training for safe driving of the vehicle driver, such questions. If the answer to the above, the precautions, etc., the image and the character information can be used to deepen the understanding of the vehicle driver, and the training effect can be enhanced. A plurality of pieces of character information to be displayed on the character display unit 62 can be registered, and can be selected from a plurality of pieces of character information and displayed on the screen of the display device 3 at the time of pause. .

  In addition, as described above, when the pause process is executed during the reproduction of the image group data, the character information is displayed. Therefore, when the acceleration acting on the vehicle as the running data reaches a dangerous level. By associating the timing of the pause process with any image data before playing back the image data, text information such as questions that can improve the training effect in a timely manner can be automatically displayed. It becomes very convenient. Further, the reproduction may be switched to the slow reproduction before reproducing the image data when the acceleration acting on the vehicle reaches a dangerous level. It may be difficult for the trainees to understand how the accident occurred or the vehicle was in danger because it was an instantaneous event until it reached a vehicle accident or a dangerous situation during driving. It is possible to make the trainees clearly recognize the process leading up to the dangerous state, and the training effect can be enhanced.

  After this temporary stop, as shown in FIG. 3, by pressing the playback button 32 displayed at an arbitrary position that does not interfere with the image display area 34 on the screen A of the display device 3 by clicking the mouse 41, The display of the character information can be erased, and the reproduction of the image group data can be resumed. Also, the stop button 33 for stopping the reproduction of the image group data that can be operated with the mouse 41 is displayed on the screen in a similar manner. Is done. The playback unit 6 also displays the acceleration data and speed data values and graphs included in the operation history data in the data display area 36 during playback of the image group data. It helps to understand the driving situation.

  The setting editing unit 8 performs various settings such as a user ID of the storage medium 10, an acceleration threshold value used in the drive recorder 11, and editing / deletion of operation history data necessary for operation management in the storage medium 10. As described above, the character information used in the character display unit 62 is set and registered in advance. In the editing of various settings, the operation management worker or the instructor in charge of the training can specify necessary items from the input device 4 to input and edit character information and the like.

  In addition, it is possible to associate the character information to be displayed at the time of suspension with the operation history data stored in the training folder 71. Further, the association of the character information to be displayed at the time of suspension is arbitrary in the operation history data. It can also be performed on image data or image group data. By this, when the image data is paused during reproduction of the image group data, automatically associated character information can be displayed.

  In the operation management device 1 configured as described above, at the time of training, the instructor can perform training by specifying the operation history data stored in the training folder 71 and reproducing the image group data. It becomes possible. Therefore, it is not necessary to perform a special operation for operation management, the training can be performed, the implementation of the training becomes very simple, and the burden on the instructor is reduced.

  In addition, if pause is executed during the display of image group data, it is possible to display text information that needs to be transmitted during training. The trainer can deepen the understanding of the vehicle driver and the like, enhance the training effect, and the instructor can display the character information with a single operation. Instructors will be able to concentrate on training.

  Furthermore, in the operation management apparatus 1, when the operation history data is read from the storage medium 10, the operation history data in the dangerous area and the operation history data at the time of dangerous driving are automatically classified and stored in the training folder 71. The instructor does not need to refer to all the operation history data, and can select the data to be used for the training from the operation history data stored in the training folder 71, so that the preparation for the training becomes very easy. .

  Further, when operating the training folder 71, it is only necessary to enable simple operations such as registration of character information to be displayed during pause, association of character information to be displayed with image data, timing to pause, etc. Even if the operator is not familiar with the operation of the operation management device 1, the person in charge of the instructor can perform the training preparation work without hesitation.

  Therefore, according to the operation management apparatus 1 in the present embodiment, it is not only suitable for operation management purposes, but can also be used for training, and training preparation and training can be performed without imposing a burden on the instructor in charge of the training. Since it can be executed, training using the operation history data can be easily performed without being familiar with the operation of the operation management device 1.

  Furthermore, the operation management device 1 is not only suitable for training for a large number of people, but can also refer to the operation history data without being familiar with the operation, so that the vehicle driver can individually refer to the operation history data to drive the vehicle. It is also possible to use it for guidance.
