  FIG. 6 is a diagram showing an overall processing flow of the drive recorder 2.

  The process flow shown in FIG. 6 is mainly executed by the CPU 20 of the drive recorder 2 in cooperation with each component of the drive recorder 2 according to the control program 41. It is assumed that the memory card 7 is inserted in the slot 24 of the drive recorder 2 and the rated voltage is supplied to the drive recorder 2 when the processing flow shown in FIG.

  When the ACC switch 57 (or IG switch 58) is turned on or the power switch 61 is turned on and the operation of the drive recorder 2 is instructed, the CPU 20 causes the first area 201 of the memory card 7 (see FIG. 7). ) Is initially set (S10), and the read setting conditions are recorded in a predetermined area (such as an internal memory of the CPU) in the drive recorder 2, and according to the setting contents, Perform the action.

  Next, the CPU 20 cyclically records image information and the like captured by the first camera 3 to the third camera 5 in the RAM 6 (S11).

  Next, the CPU 20 determines whether or not the recording condition is satisfied (S12). The case where the recording condition is satisfied means the following three cases. Note that when the recording condition is satisfied, one or two of them may be used instead of all of the following three, and other conditions other than the following three may be set.

    1. G detection: A case where the acceleration sensor 50 detects a gravitational acceleration of 0.40 G or more. The reason why the recording condition is satisfied is that when such a gravitational acceleration is applied to the vehicle 1, it can be recognized that an accident has occurred or that the accident has been imminent. The set value (0.40G) is an example, and other values can be adopted, and are included in the set conditions read in S10.

    2. Speed trigger: A case where the speed difference within a predetermined period of the vehicle 1 detected from the vehicle speed sensor 53 is equal to or greater than a threshold value. Specifically, when traveling at 60 km / h or more and the deceleration for one second becomes 14 km / h or more, it is determined that the recording condition is satisfied. The reason why the recording condition is satisfied is that when the vehicle 1 undergoes such a speed change, it can be recognized that an accident has occurred or that the accident has been imminent. Note that the above set value (deceleration for one second during traveling at 60 km / h or more, 14 km / h or more) is an example, and other values can be adopted and read in S10. It is included in the setting conditions.

    3. Imaging SW: A case where a predetermined button (imaging button; not shown) included in the operation unit 12 of the terminal 10 is operated. Image information and the like can be recorded according to instructions from the crew.

  If it is determined in S12 that the recording condition is satisfied, the CPU 20 corresponds to, for example, image information for a total of 20 seconds, 12 seconds before the recording condition is satisfied and 8 seconds after the recording condition is satisfied, and the image information. The status information to be recorded is recorded in the memory card 7 as one folder (S15). Note that the period recorded when the recording condition is satisfied (a total of 20 seconds including 12 seconds before the recording condition is satisfied and 8 seconds after the recording condition is satisfied) is an example, and another period may be selected. Is possible. Further, when the recording condition is satisfied, the drive recorder 2 includes, for example, audio information for a total of 20 seconds, 12 seconds before the recording condition is satisfied and 8 seconds after the recording condition is satisfied, together with the above-described image information. You may make it record on the memory card 7 as one folder.

  State information refers to the following information.

    1. Gravity acceleration information (G value) detected by the acceleration sensor 50.

    2. Current position information (latitude and longitude information) and current time information of the vehicle 1 detected from the GPS receiver 51.

    3. Speed information of the vehicle 1 detected from the vehicle speed sensor 53.

    4). ON / OFF information of the ACC switch 57. Instead of the information from the ACC switch 57, ON / OFF information of the IG switch 58 may be employed.

    5. ID information of the imaged camera.

  Note that the content of the state information is not necessarily limited to the above information, such as information on the engine rotation status, information on the accelerator opening, information on the cumulative travel distance since the drive recorder 2 was mounted, etc. Other information may be included.

  If it is determined in S12 that the recording condition is not satisfied, the CPU 20 determines whether the constant recording is set in the setting condition read in S10 (S13).

  If it is determined in S13 that continuous recording has been set, the CPU 20 performs continuous recording (S14). In the continuous recording, regardless of the establishment of the recording condition, a predetermined number of pieces of image information (for example, one piece per minute) and state information corresponding to the image information are recorded in the memory card 7 at predetermined intervals.

  Next, the CPU 20 determines whether or not the mode has been changed to the setting condition change mode (S16). If it is determined that the mode has been changed to the setting condition change mode, the setting condition change process (S17) and The changed setting condition is stored (S18).

  In the storage process (S18), the CPU 20 records the changed setting conditions in the first area 201 of the memory card 7 and a predetermined area in the drive recorder 2 (such as the internal memory of the CPU), and then changes. Various operations of the drive recorder 2 are executed based on the set conditions.

  Further, the CPU 20 separately records the setting condition immediately before the change in the first area 201 of the memory card 7 in the storage process (S18). With this process, the drive recorder 2 can refer to the past setting conditions later, and even if the setting conditions are changed in the middle, under what setting conditions the image information before the change is made, etc. It became possible to grasp clearly what was recorded in. As a result, it is possible to accumulate in a complete form know-how for determining under what setting conditions image information and the like are recorded most efficiently and usefully.

  Next, the CPU 20 determines whether or not an end signal based on the OFF signal of the ACC switch 57 or the OFF signal of the power switch 61 has been received (S20). When the end signal is received, the series of processing ends. To do. If the end signal has not been received, S12 to S20 are repeatedly executed.

  As described above, the drive recorder 2 cyclically records image information, status information, and the like in the RAM 6 while predetermining a predetermined image when the recording condition is satisfied and when recording is always performed (the recording may not always be performed). Information, status information, and the like are recorded in a predetermined area of the memory card 7. Further, as will be described later, the drive recorder 2 can record predetermined information in a predetermined area of the memory card 7 even when a condition for determining violation items used for eco / safety driving diagnosis is satisfied. is there. Further, the drive recorder 2 can record operation information in a predetermined area of the memory card 7 as will be described later.

  FIG. 7 is a diagram illustrating a usage example of the recording area of the memory card 7.

  The recording area 200 of the memory card 7 includes a first area 201 in which various information such as a crew member's name and setting conditions are recorded, and a second area in which image information and state information are recorded when the recording conditions are satisfied. 202, a third area 203 in which image information and state information by continuous recording are recorded, and a fourth area 204 in which operation-related information and violation item information are recorded are allocated.

  When the drive recorder 2 is attached to all the vehicles in order to manage and manage a plurality of trucks in a shipping company or the like, the recording conditions are established in the second area 202 in consideration of the truck operating conditions. In this case, it is preferable that the image information and the status information have a recording capacity capable of recording at least 15 events, and the third area 203 has a recording capacity capable of recording the image information and the status information by continuous recording for at least 8 hours. It is preferable to have.

  FIG. 8 is a diagram illustrating a video image acquisition method. FIG. 8A, FIG. 8B, and FIG. 8C each show an example of an image acquisition method from three cameras.

  In FIG. 8A, an image from the first camera 3 is acquired at time T0, an image from the second camera 4 is acquired at time T1, an image from the first camera 3 is acquired at time T2, and the time At T3, an image from the third camera is acquired, and thereafter, an image from each camera is repeatedly acquired in the same order. Switching of the video image is performed by the video SW 21 according to a control signal from the CPU 20. As will be described later, since the image IC 22 outputs still image information at a rate of 30 frames per second (30 fps), the video SW 21 may be switched at 1/30 second intervals accordingly. In continuous recording, images from each camera may be repeatedly acquired at intervals of 1 minute in the order shown in FIG.

  In FIG. 8B, an image from the first camera 3 is acquired at time T0, an image from the second camera 4 is acquired at time T1, an image from the third camera 5 is acquired at time T2, and the time At T3, an image from the first camera is acquired, and thereafter, an image from each camera is repeatedly acquired in the same order. Switching of the video image is performed by the video SW 21 according to a control signal from the CPU 20. As will be described later, since the image IC 22 outputs still image information at a rate of 30 frames per second (30 fps), the video SW 21 may be switched at 1/30 second intervals accordingly. In continuous recording, images from each camera may be repeatedly acquired at 1 minute intervals in the order shown in FIG.

  In FIG. 8C, the order in which video images are acquired from each camera is the same as that in FIG. 8B, but the intervals are changed. That is, the interval from time T0 to time T2 is 1/30 second interval, and the interval between time T2 to time T3 and time T3 to time T4 is 1 minute interval.

  As described above, it is possible to appropriately acquire video images from the three cameras by switching the video SW 21 at a predetermined timing by a control signal from the CPU 20. In the three examples described above, the ratio of acquiring video images from the first camera 3 that captures the front front of the vehicle 1 is set to be large (so that the amount of information increases). An appropriate ratio can be determined by setting conditions according to the position and number. In any of the photographing methods, the first camera 3 is preferentially recorded as compared with other cameras, because the first camera 3 is a camera that reflects the front of the vehicle and is more important than the other cameras. is there.

  FIG. 9 is a diagram illustrating an example of a recording method on the memory card.

  The image IC 22 outputs image information to the RAM 6 at 640 × 480 pixels and 30 frames / second based on the video image switched by the video SW 21, and the RAM 6 receives the image information for 40 seconds input from the image IC 22. It is stored cyclically. For example, when the video SW 21 is switched in the order of FIG. 8A, the image information of the first camera 3 → the image information of the second camera 4 → the image information of the first camera 3 → the image information of the third camera 5 → The image information is output to the RAM 6 in the order of the image information of the first camera 3. The RAM 6 is also set so that status information corresponding to each image information is also recorded. When the recording condition is satisfied and when the recording is always performed, the image information and the status information are output from the RAM 6 to the memory card 7 and recorded at a predetermined timing. Further, depending on the setting conditions, the audio information acquired by the microphone 26 may be stored cyclically in the RAM 6 and recorded in the memory card 7 at a predetermined timing.

  FIG. 9 shows an example of recording on the memory card 7 from time T10 to time T14, and it is assumed that the recording condition is satisfied at time T12.

  When the recording condition is satisfied at time T12, for example, among the image information recorded in the RAM 6 in a circular manner, the CPU 20 starts from 12 seconds before the recording condition is satisfied (time T11) to 8 seconds after the recording condition is satisfied (time The image information and status information for 20 seconds until T13) are output to the slot 24. As a result, 30 × 20 = 600 frames of still image information from time T11 to time T13 is recorded in the second area 101 of the memory card 7 as one file.

  In the continuous recording, for example, the CPU 20 outputs one piece of image information and status information corresponding to the image information among the image information and the like that are cyclically recorded in the RAM 6 to the slot 24 every second. As a result, the still image information at time T10 to time T14 is recorded in the third area 203 of the memory card 7.

  Note that voice recording can be performed even in the case of continuous recording. In that case, when acquiring image information at a predetermined timing and a predetermined frame rate, audio information for each predetermined period (for example, audio information for every 10 seconds when acquiring one piece of image information per minute) To get and record.

  As described above, the drive recorder 2 can record information for steady recording on the memory card 7 for a long time, and also provides detailed and clear information to the memory card 7 in an important period where there is a possibility of a serious accident or the like. It became possible to record. Note that the frame rate and the recording time when the above-described recording condition is satisfied and when recording is always performed are merely examples, and the present invention is not limited to these, and various conditions can be set by changing the setting conditions.

  By the way, in the example of FIG. 9, at time T11 to T13, the recording by the establishment of the recording condition and the recording by the constant recording are overlapped. Therefore, in order to efficiently use the recording capacity of the memory card 7, it is preferable that the recording is not always performed at times T11 to T13, particularly at times T12 to T13 after the recording condition is satisfied.

  In the above-described example, it is set so that the image information and the status information are acquired and recorded in the memory card 7 in synchronization in the recording by the establishment of the recording condition and the continuous recording. However, if the acquisition speed of image information is faster than the writing speed to the memory card 7 or the allocated area of the memory card 7 is full, the image information and the status information are synchronized. In some cases, it could not be recorded. However, even in such a state, in fact, only state information with a small capacity may be recorded on the memory card 7. Therefore, the image information and the status information may be set to be recorded in the memory card 7 at different timings. As described above, when the image information and the state information are set to be recorded at different timings, only the state information may be recorded without losing all the information. It becomes possible to grasp and guess later whether or not a situation has occurred using the state information. Note that it is preferable that whether image information and state information are recorded on the memory card 7 synchronously or on the memory card 7 at different timings can be set according to setting conditions described later.

  FIG. 10 is a diagram illustrating a method for forming thumbnail images.

  FIG. 10A shows the image information that is cyclically recorded in the RAM 6, as in FIG. The still image information for 600 sheets (30 fps × 20 s) for 20 seconds until time T13 corresponding to 8 seconds after the establishment of is shown. Although not clearly shown in FIG. 10A, each piece of still image information is stored in the order described in FIG. 8A (first → second → first → third → first →... ), Still image information corresponding to video images captured by the first camera 3 to the third camera 5 is recorded in order.

  As described above, when any one of the three recording conditions is satisfied, the CPU 20 performs 20 seconds from time T11 corresponding to 12 seconds before the recording condition is satisfied to time T13 corresponding to 8 seconds after the recording condition is satisfied. , The still image information for 600 sheets (30 fps × 20 s) is collected as one folder and recorded on the memory card 7 (see S15 in FIG. 6).

  Further, as will be described later, when the playback apparatus 400 plays back image information that satisfies the recording conditions, a thumbnail based on a representative image is used to distinguish a specific image from many recorded images. An image (an image obtained by reducing the image) is created and displayed, and may be used as an index for each recorded image. Needless to say, image information at the time when the recording condition is satisfied is preferable as a representative image.

  However, as shown in FIG. 10C, since the image information at the time when the recording condition is satisfied is in the substantially central portion of the folder, the playback device 400 searches the image information at the time when the recording condition is satisfied. There is a problem that a lot of processing time is required to form thumbnail images corresponding to many recorded images.

  Therefore, in the drive recorder 2, as shown in FIG. 10B, when the CPU 20 forms a folder on the memory card 7, the still image information 210 at the time when the recording condition is satisfied is specified and used for the thumbnail image. The still image information 210 is set to be copied immediately after the folder header 212. Therefore, in the playback apparatus 400, when creating a thumbnail image as an index of the Nth folder, it is sufficient to use still image information immediately after the header 212, and the search time shown in FIG. 10C is not required. There are advantages. The header 212 records data such as the ID of the vehicle on which the drive recorder 2 is mounted, the driver's ID, the date and time when the recording condition is satisfied, and the type of recording condition that is satisfied.

  Instead of automatically selecting still image information at the time when the recording condition is satisfied as still image information for the thumbnail image, the image is captured by a specific camera (for example, the first camera 3) immediately after the recording condition is satisfied. More preferably, still image information based on video images is always selected. This is because when still image information captured by a plurality of cameras is alternately recorded, it is more useful as an index that the thumbnail image is always the still image information captured by a specific camera.

  Note that the thumbnail image can be used not only when the recorded image is reproduced in the reproduction apparatus 400 but also as an index when the recorded image is reproduced in the display unit 11 of the terminal 10.

  FIG. 11 is a diagram illustrating an example of a method for reproducing image information.

  FIG. 11A is a diagram showing an example of the Nth folder including still image information recorded on the memory card 7 according to the order of FIG. 8A when the recording condition is satisfied. As described with reference to FIG. 10B, the still image information 211 for the thumbnail image is copied to the Nth folder immediately after the header 212, and then the total captured by the first camera 3 to the third camera 5 600 pieces of still image information are included in order along the direction of arrow A.

  As described above, since the image information captured by the three cameras is alternately included, when the image information is reproduced as it is, a plurality of viewpoints are switched at an early timing, and the moving image becomes very difficult for the crew to view. Therefore, in particular, when playing back on the display unit 11 of the terminal 10, it is preferable to perform control so that only still images captured by a predetermined camera are played back continuously.

  FIG. 11B is a diagram showing a case in which still image information captured by the second camera 4 among the still image information recorded alternately is reproduced in order along the direction of the arrow B. . The CPU 20 identifies the camera on which the still image information is captured based on the state information recorded corresponding to each still image information, and corresponds to a preset camera (for example, the second camera 4). Control is performed so that only the still image information is selected and reproduced on the display unit 11. A camera that captures image information to be reproduced is set in advance by a method described later. By such control, image information captured by a plurality of cameras can be recorded alternately and can be easily reproduced by the crew.

  In the playback device 400, when playing back, as will be described later, it is possible to form a plurality of screens on one screen and play back moving images captured by three cameras at once (see FIG. 21). ).

  Hereinafter, setting of setting conditions (operation conditions of the drive recorder 2) and changing of the settings will be described.

  The setting conditions described later are recorded in the first area 201 of the memory card 7 at the same time when the operation plan information described later is recorded in the memory card 7 (see the processing flow S102 in FIG. 13). In this case, the setting condition to be recorded is determined in advance by the operation manager side of the playback device 400. However, when it is desired to change the preset setting conditions, the setting conditions can be changed using the operation unit 12 of the terminal 10 connected to the drive recorder 2 in accordance with a setting condition changing flow described later.

  In addition, a plurality of setting conditions are recorded in the memory card 7 in advance, and after inserting the memory card 7 into the drive recorder 2, one of the setting conditions is selected using the operation unit 12 of the terminal 10. You may do it. For example, it is possible to set a plurality of setting conditions in advance such that the setting condition A is for a large truck, the setting condition B is for a light truck, and the setting condition C is for a taxi. The means for selecting the setting condition is not limited to the operation unit 12 of the terminal 10, and other operation means such as a photographing SW may be used.

  Furthermore, the correspondence relationship between the crew ID or vehicle ID and the setting condition is recorded in advance in the memory card 7, and after inserting the memory card 7 into the drive recorder 2, the crew member ID or When the vehicle ID is input, the CPU 20 may be set to automatically select a setting condition corresponding to the input crew ID or vehicle ID.

  FIG. 12 is a diagram showing an outline of a setting condition changing flow.

  The process flow shown in FIG. 12 shows the details of S17 and S18 of FIG. 6, and is mainly executed by the CPU 20 of the drive recorder 2 using the terminal 10 in accordance with the control program 41. It is assumed that the memory card 7 is inserted in the slot 24 of the drive recorder 2 and the rated voltage is supplied to the drive recorder 2 when the processing flow shown in FIG.

  First, when a predetermined operation is performed on the operation unit 12 of the terminal 10 to enter the maintenance mode, the setting mode (S30) for changing a preset setting condition and the preset setting condition are browsed. The inspection mode (S31) can be selected.

  In the setting mode (S31), when the setting conditions are actually changed, the vehicle number or crew ID of the vehicle 1 is input as a password, and matches the vehicle ID or crew ID of the vehicle 1 recorded in advance. It is preferable that the setting condition can be changed only in the case.

  When the setting mode (S31) is entered, as shown in FIG. 12, it is possible to change the settings for 10 items from “basic item (S40)” to “voice recording item (S49)”. The “basic item (S40)”, “image recording item (S45)”, and “always recording item (S46)” further have a plurality of fine setting items. The crew member operates the operation unit 12 of the terminal 10 to select an item whose condition setting is to be changed, and changes the specific condition setting. Each item will be described below. Note that the transition to the maintenance mode and the operation in the mode are not limited to the operation by the operation unit 12 of the terminal 10.

1. When “Basic Item (S40)” is selected, “Date / Time Setting Item (S60)”, “Equipment Installation Direction Item (S61)”, and “Camera Connection Number Item (S62)” are further selected. It is possible.

  When a date / time setting item is selected, settings such as date / time and vehicle number can be changed. When the device installation direction item is selected, the setting of the installation direction of the main body of the drive recorder 2 can be changed. The installation direction of the main body of the drive recorder 2 is set because which of the three axes of the built-in acceleration sensor 50 corresponds to the longitudinal direction of the vehicle 1 and which axis corresponds to the lateral direction of the vehicle 1. It is for determining. When the number of cameras connected item is selected, settings such as the number of cameras connected to the drive recorder 2 and the above-mentioned camera standards (selection of dedicated cameras having capture frequencies not affected by blinking / NTSC standard cameras), etc. It is possible to change.

2. “Buzzer guidance item (S41)” When the buzzer guidance item is selected, settings such as the volume level of the buzzer 27, the level of the buzzer 27, and the presence / absence of a buzzer sound when the recording conditions are met are set. It is possible to change.

3. About “Vehicle Speed Item (S42)” When the vehicle speed item is selected, it is possible to change settings such as the system of pulses output from the vehicle speed sensor 53 connected to the drive recorder 2 and the type of the vehicle speed sensor. is there.

4). About “Dangerous Driving Item (S43)” When a dangerous driving item is selected, it is possible to change the setting of the judgment condition of the violation item used for the eco / safety driving diagnosis. Below, 6 example violation items used for eco-safe driving diagnosis will be described. However, the six violation items used for the eco-safety driving diagnosis shown below are examples, and other items can be adopted.

    B) Excessive speed: When the vehicle 1 is driven at a speed higher than a predetermined speed (for example, 80 km / h at the initial setting) on a general road for a predetermined time (for example, initial setting, 10 seconds) or more, and at a predetermined speed ( For example, the initial setting is a case where the vehicle is driven at a speed higher than 100 km / h) for a predetermined time (for example, initial setting, 10 seconds) or more. When the above condition is satisfied, the CPU 20 records the occurrence of “overspeed” in the first area 201 of the memory card 7. If the above speed excess condition is satisfied a plurality of times while the vehicle 1 is traveling, the number of satisfied conditions is also recorded in the memory card 7.

    (B) Rapid acceleration: A case where the speed increases for a predetermined time (for example, the initial setting is 1 second) or more by a predetermined increase value (for example, the initial setting is 13 km / h). When the above condition is satisfied, the CPU 20 records that the “rapid acceleration” has occurred in the first area 201 of the memory card 7. In addition, when the conditions for the rapid acceleration are satisfied a plurality of times while the vehicle 1 is traveling, the number of satisfied conditions is also recorded in the memory card 7. A determination acceleration value (for example, 0.3 G or more) can be determined together with the predetermined time and the predetermined increase value.

    (C) Rapid deceleration: A case where the speed is reduced by a predetermined decrease value (for example, the initial setting is 13 km / h) or more during a predetermined time (for example, the initial setting is 1 second). When the above condition is satisfied, the CPU 20 records that “rapid deceleration” has occurred in the first area 201 of the memory card 7. In addition, when the above-mentioned rapid deceleration condition is satisfied a plurality of times while the vehicle 1 is traveling, the number of satisfied times is also recorded in the memory card 7. A determination acceleration value (for example, 0.3 G or more) can be determined together with the predetermined time and the predetermined decrease value.

    D Steep steering: A case where the gravitational acceleration in the left-right direction of the vehicle 1 is equal to or greater than a predetermined detection value (for example, the initial setting is 0.45 G) for a predetermined time (for example, the initial setting is 500 milliseconds). When the above condition is satisfied, the CPU 20 records the occurrence of the “steep handle” in the first area 201 of the memory card 7. In addition, when the condition of the sudden handle is satisfied a plurality of times while the vehicle 1 is traveling, the number of satisfied conditions is also recorded in the memory card 7.

    Wheeling: A case where the output of the ACC switch 57 (or the IG switch 58) is ON and the speed of 0 km / h continues for a predetermined time (for example, the initial setting is 5 minutes) or more. When the above condition is satisfied, the CPU 20 records the occurrence of “idling” in the first area 201 of the memory card 7. Note that if the idling condition is satisfied a plurality of times while the vehicle 1 is traveling, the number of established conditions is also recorded in the memory card 7.

    F Long-time operation: A case where the output of the ACC switch 57 (or IG switch 58) has not been turned OFF for a predetermined time (for example, the initial setting is 2 hours) or longer. When the above condition is satisfied, the CPU 20 records that the “long-time operation” has occurred in the first area 201 of the memory card 7. In addition, when the long-time driving condition is satisfied a plurality of times while the vehicle 1 is traveling, the number of satisfied times is also recorded in the memory card 7.

5). Regarding “Recording Condition Item (S44)” When the recording condition item is selected, the G detection (for example, the initial setting is 0.40 G or more is 100 milliseconds or more) and the speed among the above-mentioned three recording conditions. It is possible to change the setting of a trigger (for example, the initial setting is a deceleration of 1 km or more during traveling at 60 km / h or more). Of the three recording conditions described above, the other one is only the ON / OFF of the imaging SW. Therefore, the setting cannot be changed in this example. However, the setting can be changed using this item. It may be configured as possible. Furthermore, when other conditions other than the three recording conditions described above are set, it is preferable that the setting can be changed using this item.

6). When “Image Recording Item (S45)” is selected, “Frame Rate Item (S70)”, “Recording Number Item (S71)”, and “Recording Time Item (S72)” are further selected. It is possible.

  When the frame rate item is selected, the output setting (for example, the initial setting is shown in FIG. 8A) of each camera (the first camera 3 to the third camera 5 in this example) connected to the drive recorder 2. In the order shown, it is possible to change 30 × 2/4 fps for the first camera 3, 30/4 fps for the second camera 4, and 30/4 fps for the third camera 5. When the recording count item is selected, the setting of the number of folders to be recorded in the second area 202 of the memory card 7 (for example, the initial setting is 15) can be changed when the recording condition is satisfied. is there. When the recording time item is selected, the recording time to be recorded when the recording condition is satisfied (for example, the initial setting is 20 seconds in total from 12 seconds before the recording condition is satisfied to 8 seconds after the recording condition is satisfied). It is possible to change the setting.

7). Regarding “always recording item (S46)” When the always recording item is selected, “always recording / non-recording item (S80)”, “always recording camera item (S81)”, “frame rate item (S82)” ) ”,“ Always recording upper limit item (S83) ”, and“ voice recording item (S84) ”.

  When the item with / without constant recording is selected, it is possible to change the setting for whether or not to perform constant recording (see S13 in FIG. 6) (for example, the initial setting is with constant recording). . When the constantly recording camera item is selected, it is possible to change the setting of the camera that captures image information to be recorded constantly (for example, the initial setting is the first camera 3). If the frame rate item is selected, it is possible to change the setting of the frame rate (for example, the initial setting is 1 fpm: 1 frame per minute) for continuous recording. When the always recording upper limit item is selected, the setting of the upper limit (for example, the initial setting is 512 MB) of the capacity of the third area 203 of the memory card 7 that always records can be changed. If a voice recording item is selected, it is possible to change the setting of whether or not voice recording is being performed at all times (for example, the initial setting is no voice recording).

8). Regarding “Video Output Item (S47)” When the video output item is selected, when the image information recorded on the display unit 11 of the terminal 10 is reproduced, the camera that captures the image information to be reproduced (see FIG. 11). (For example, the initial setting is the first camera 3) can be changed.

9. “SW Item (S48)” When the SW item is selected, what happens when the imaging SW (imaging SW included in the operation unit 12 of the terminal 10) is pressed as one of the conditions for establishing the recording condition? It is possible to change the setting for recording various information (for example, the initial setting is image information + audio information) and the number of recordings (for example, the initial setting is 5 times).

10. “Voice recording item (S49)” When voice recording is set when the imaging SW as one of the conditions for establishing the recording condition is pressed (see “SW item (S48)”), once It is possible to change the setting of the recording time of voice recording by pressing (for example, the initial setting is 10 minutes).

  When the change of the setting item described above is completed, the process proceeds to the storage mode (S90), and whether the changed setting is to be stored (S91) or not to be stored (S92) is selected, and the setting mode 30 is ended. Note that the storage mode (S90) corresponds to S18 in FIG. 6, and changes in the settings are saved (S91), and thereafter, various functions of the drive recorder 2 are executed under the changed conditions. Further, the conditions before the setting change are also recorded, and not only the latest setting conditions but also the previous setting conditions are recorded in the memory card 7.

  As described above, since the setting condition of the drive recorder 2 can be changed, the setting can be adjusted individually after the drive recorder 2 is attached to the vehicle, so that the number of work steps at the time of attachment can be reduced. became. Further, since the setting conditions (initially set conditions and setting conditions changed thereafter) are recorded in the memory card 7, image information and the like recorded by inserting the memory card 7 into the playback device 400 are stored. When moving from the memory card 7 to the playback device 400, it is possible to copy the setting conditions relating to a predetermined vehicle recorded on the memory card 7 to the playback device 400. As a result, the reproducing apparatus 400 can record the copied setting conditions in the memory card 7 used for another vehicle, and reflect the same setting conditions to the other vehicle. Furthermore, the memory card 7 in which the setting conditions (initially set conditions and subsequently changed setting conditions) are recorded is directly inserted into the drive recorder of another vehicle, and the setting conditions recorded in the memory card 7 Thus, it is possible to control the drive recorder. Accordingly, it is possible to easily reflect the same setting condition on other vehicles without using the playback device 400.

  In the above-described example, the drive recorder 2 is configured such that the set condition can be changed for each item using the operation unit 12 of the terminal 10. However, a plurality of patterns (A pattern (for truck), B pattern (for taxi), C pattern (for delivery), etc.) are prepared in advance for each type, function or application of the vehicle, and the setting conditions are collectively set. You may comprise so that it may change.

  In addition, as described above, it is set whether to record the image information and the state information on the memory card 7 in synchronization or at different timings in the recording when the recording condition is satisfied and the continuous recording. It is also possible to determine by conditions.

  FIG. 13 is a diagram illustrating an example of a process flow of operation management.

  Operation management refers to management of business vehicles that carry goods and the like. In the present application, a method for executing operation management of a vehicle 1 (for example, a truck) equipped with the drive recorder 2 more effectively and simply using various information acquired by the drive recorder 2 will be described.

  The process flow shown in FIG. 13 is mainly executed by an operation manager (or operator) using the playback device 400.

  First, the operation manager makes an operation plan for the vehicle 1 by using a predetermined application program installed in advance on the recording medium 407 of the playback device 400 (S100).

  FIG. 14 is a diagram illustrating an example of a screen for performing an operation plan.

  The operation manager causes the display unit 406 to display a screen 410 for performing an operation plan shown in FIG. 14 by a predetermined operation by the operation unit 405 from the initial screen. The screen 410 includes a crew member list 420, a vehicle list 430, a schedule calendar 440, a route master list 450, an operation plan entry field 460, and other control buttons 470-475. Note that the screen 410 is an example, and the present invention is not limited to this.

  The operation manager selects a predetermined crew from the crew list 420, selects a predetermined vehicle from the vehicle list 430, selects a predetermined month and day from the schedule calendar 440, and enters a predetermined operation plan in the operation plan entry field 460. By inputting, a predetermined crew member (for example, “Crew Ichiro” 421) uses a predetermined vehicle (for example, vehicle number “10001” 431) to determine a predetermined date (for example, “January 9, 2009”). An operation plan for performing a predetermined operation (see, for example, the operation plan entry field 460 on the screen 410) on the “day” 443) can be easily set on the screen. To register the operation plan set on the screen, register button 470, to delete the operation plan set on the screen, delete button 471, to edit edit button 473, to display the map The user clicks the map display button 473 using the operation unit 405, clicks the print button 474 to print the screen 410, and clicks the return button 475 to return to the initial screen.

  In the screen 410, the operation manager inputs the operation plan in the operation plan entry field 460 using the operation unit 405, but the frequently used route is recorded in advance in the route master list 450, and the route It is preferable that the operation plan entry field 460 is automatically entered by selecting (for example, route A).

  In the schedule calendar 440, when an operation plan is already registered for the same crew member (for example, “Crew Ichiro” 421), it is preferable that predetermined marks 444 to 447 are displayed on the schedule calendar 440. . The predetermined mark may be expressed by a background color of a date, a character color, or the like. In addition, the schedule calendar 440 can confirm the past results and future plans by switching the display month using the previous month display button 441, the next month display button 442, and the like. The schedule calendar 460 displays a list of dates, but a separate monthly list may be provided so that it can be seen at a glance whether a schedule is assigned to each month. Furthermore, the type of the selected route master may be identified by the color of a predetermined mark added to the date, or the route direction (the Kanto direction, the Kansai direction, etc.) may be identified. Furthermore, you may make it change the color and kind of the predetermined | prescribed mark added to a date during operation plan work execution and after registration.

  Further, by clicking a predetermined mark added to the date of the schedule calendar 440, an already executed operation plan or an operation plan scheduled to be executed in the future is displayed as shown on the screen 410. . Furthermore, by dragging a predetermined mark added to a date and dropping it on a date without another predetermined mark, it is possible to register an operation plan of the same content as an operation plan of another date. It is preferable to do so. Furthermore, by dragging a date without a predetermined mark and dropping it on a date with a predetermined mark, the operation plan registered on the date with the predetermined mark can be canceled. It is preferable to make it. Note that the above drag-and-drop function is not limited to a single day, and can be performed by dragging multiple days (for example, from January 9, 2009 to January 16, 2009, and from February 13, 2009 to 2009). It is preferable to be applicable to (dropped on February 20, 2012).

  In the screen 410, the schedule management in the schedule calendar 440 is performed based on the crew selected in the crew list 420, but may be performed based on the selected vehicle instead of the crew. For example, registered operation management information regarding a predetermined vehicle selected in the vehicle list 430 may be displayed on the schedule calendar 440 by the method described above.

  Next, the operation manager confirms the route of the operation plan prepared in S100 (S101). The route confirmation is performed by clicking the map display button 473 on the screen 410. In response to the click of the map display button 473, the playback device 400 searches the map information recording unit 408 to acquire a map screen on which the work place input in the operation plan entry field 460 is displayed, and acquires the acquired map screen. Create and display a route confirmation screen with the work location on top.

  FIG. 15 is a diagram illustrating an example of a screen for performing route confirmation.

  In the screen 480 shown in FIG. 15, a crew name and scheduled operation date display area 481, a planned operation plan display area 482, a detailed display area 483, a print button 484, a return button 485 to the screen 410, and a map display area 490 are displayed. Contains. The screen 480 is an example, and the present invention is not limited to this.

  In the map display area 490, work places 491 to 494 in the operation plan planned on the screen 410 are displayed as balloons 01 to 04. The balloon numbers 01 to 04 displayed in the map display area 490 correspond to the operations NO1 to 4 displayed in the operation plan area 482, respectively. FIG. 15 shows a state in which the balloon 01 is selected, and detailed information on the work place corresponding to the balloon 01 is displayed in the detailed display area 483.

  By checking the screen 480, the operation manager can visually check whether there is a problem in the positional relationship of the work places in the operation plan planned on the screen 410. In addition, if there is an error in the work location, the details of the work location may be changed by dragging and dropping the balloon and moving it to another location on the appropriate map. preferable. For example, when the position of the balloon 02 set as the loading place and the position of the balloon 03 set as the unloading place are opposite, by exchanging the balloons 02 and 03 by drag and drop on the map, It is preferable that the operation plan entry field 460 on the screen 410 and the operation plan display area 482 on the screen 480 are automatically rewritten and displayed accordingly. This makes it possible to improve the efficiency of the operation plan correction work.

  Note that when correction or the like is performed, it is preferable to return to the screen 410 using the return button 485 and confirm the correction content. As described above, it is possible to efficiently plan, correct, and confirm the operation plan using the screens 410 and 480.

  Next, the operation manager records the operation plan planned and confirmed in S100 and S101 on the memory card 7 used in the drive recorder 2 mounted on the vehicle 1 used by the subject crew (S102). . For example, the screen 410 (see FIG. 14) or the screen 480 (see FIG. 15) may be shifted to a recording screen for a memory card, and the planned and confirmed operation plan may be directly recorded on the memory card 7. Furthermore, the playback device 400 may record the setting conditions of the drive recorder 2 described with reference to FIG. This is particularly effective when the operation manager side intends to change the settings of the drive recorder 2 at once.

  By the way, when there are a plurality of operation plans related to a plurality of crew members, it is efficient to perform operation management planning and recording work to the memory card 7 individually. Therefore, a processing flow in the case where the operation management planning and the recording work to the memory card 7 are individually performed will be described below.

  FIG. 16 is a diagram illustrating an example of a recording process flow of an operation plan to a memory card.

  The processing flow shown in FIG. 16 is executed by operation of the operation unit 405 of the operation manager (or operator) in accordance with an application program recorded in advance on the recording medium 407 of the playback device 400. It is assumed that a predetermined memory card 7 is inserted into the slot 404 when the processing flow shown in FIG.

  First, the reproducing device 400 acquires a target crew member name (S110). The crew name may be selected by the operation manager from a portion such as the crew list 420 shown in FIG. 14, or the crew name or ID number is input to the playback device 400 using the operation unit 405. You may do it.

  Next, the reproducing device 400 acquires the closing time information (S111). The closing time information means the end point of the day based on the company or organization that manages the operation. In the taxi industry, in consideration of late-night service, when closing on January 9, 2009, for example, AM4: 00 on January 10, 2009, instead of 24:00 on January 9, 2009 There is.

  Next, the playback device 400 acquires the operation plan information already recorded in the memory card 7 from the fourth area 204 of the memory card 7 (S112), and records it in consideration of the closing time information acquired in S111. It is determined whether or not the operation plan information being deleted is deleted (S113). The operation plan information refers to information on the scheduled start date of the operation plan, information described in the operation plan entry column 460 in FIG. 14, position information (latitude and longitude information) of each work place, and the like.

  Judgment whether or not to delete the recorded operation plan information is performed by comparing the scheduled start date included in the recorded operation plan information with the current date in consideration of the closing time information acquired in S111. Do it. For example, if the closing time information is AM 4:00 on the next day, the scheduled operation start date is January 9, 2009, and the current date is January 10, 2009 AM 3:00, the operation plan will be executed from now on. The operation plan information recorded in the memory card 7 is stored as it is (S114). On the other hand, if the closing time information is AM 4:00 on the next day, the scheduled operation start date is January 9, 2009, and the current date and time is January 11, 2009 AM 3:00, the operation plan has already been executed. As a result, the operation plan information recorded in the memory card 7 is deleted (S115).

  Note that the determination as to whether or not to delete the recorded operation plan information may be based on the date and time instead of the date and time. In that case, it is necessary to input not only the scheduled operation date but also information related to the scheduled operation start time for each operation plan information. Further, when determining whether or not to delete the operation plan information recorded based on the date and time, it is determined whether or not the operation start scheduled time is before the current time. However, since there is a possibility that the start of operation will be somewhat delayed, even if the current date and time is past the scheduled start date and time, see the allowance time (eg 2 hours) If so, it is preferable to determine that there is a possibility that it will be executed from now on and set it not to be erased. Further, it is preferable that the allowance time can be varied using the operation unit 405.

  Next, the playback device 400 searches the recording medium 407 with the crew name acquired in S110, extracts all the operation plan information corresponding to the crew acquired in S110 (S116), and the extracted operation plan information. Of these, it is determined whether or not there is operation plan information that is not recorded in the memory card 7 (S117). If there is operation plan information that is not recorded in the memory card 7 in S117, the latest operation plan information is recorded in the fourth area 204 of the memory card 7 (S118). In S117, when there is no operation plan information that is not recorded in the memory card 7, a warning to that effect is displayed (S119), and the series of operations is terminated.

  In S113, the scheduled start date included in the recorded operation plan information is compared with the current date. If the scheduled start date has passed, it is determined that the operation plan has already been executed. The operation plan information was deleted. However, the playback device 400 searches for operation daily report information to be described later, and if operation daily report information corresponding to the operation plan information exists, the reproduction device 400 determines that the operation plan has already been executed and uses the operation plan information. However, if the daily operation report information corresponding to the operation plan information does not exist, it may be determined that the operation plan has not been executed and the operation plan information may be deleted. When daily operation report information corresponding to the operation plan information does not exist, an operation daily report corresponding to the operation plan information (no operation record) may be created assuming that the operation plan has not been executed.

  Next, the crew member inserts the memory card 7 in which the operation plan information and the setting conditions are recorded into the drive recorder 2 mounted on the vehicle 1 and performs the operation according to the operation plan (S103). During the operation, the operation plan information is displayed on the display unit 11 of the terminal 10, and the crew inputs various operation information using the operation unit 12 of the terminal 10. The CPU 20 of the drive recorder 2 sequentially records the input operation information in the fourth area 204 of the memory card 7.

  The input operation information includes arrival at the work place, departure from the work place, work, loading, unloading, resting, refueling, etc., traveling on a highway, traveling on a general road, and the like. In addition, it is preferable to provide a dedicated button corresponding to each operation information on the operation unit 12 of the terminal 10 so that each operation information can be easily input.

  In addition to the operation information, the drive recorder 2 further performs recording and / or continuous recording based on the establishment of recording conditions based on image information, status information and audio information, and detects violation items used for eco / safe driving diagnosis. Then, recording is sequentially performed in a predetermined area of the memory card 7.

  By the way, the arrival at the work place and the departure from the work place may be manually input by the crew using the operation unit 12 of the terminal 10, but the function of the drive recorder 2 is used as shown below. Alternatively, it may be determined automatically and recorded. Hereinafter, automatic determination of arrival at the work place and departure from the work place will be described.

  FIG. 17 is a diagram illustrating an example of a departure and arrival determination process flow.

  The processing flow shown in FIG. 17 is mainly executed by the CPU 20 of the drive recorder 2 in cooperation with each component of the drive recorder 2 according to the control program 41. It is assumed that the memory card 7 is inserted in the slot 24 of the drive recorder 2 and the rated voltage is supplied to the drive recorder 2 when the processing flow shown in FIG.

  First, the CPU 20 acquires an ON / OFF signal from the ACC switch 57 (S120), and determines whether or not the signal has been changed from OFF to ON (S121). That is, in S121, it is determined whether or not the crew member operates the key cylinder to start the engine.

  Next, when the engine of the vehicle 1 on which the drive recorder 2 is mounted is started, the CPU 20 acquires GPS information (current position information) from the GPS receiver 51 (S122), and the vehicle 1 is based on the current position information. It is determined whether or not has moved out of the first area (S123). The first area can be determined as an area having a predetermined radius from the point based on position information corresponding to the work place indicated as work NO1 in the operation plan information recorded in the memory card 7. For example, in the example illustrated in FIG. 14, the first area can be defined as an area within a radius of 500 m from the point based on the position information of “XX office” indicated as work NO1 for performing work.

  When the engine is started (S121) and the vehicle 1 moves out of the first area, the CPU 20 determines that it has departed from the first point (for example, “XX office where work is performed”) (S124). .

  Next, the CPU 20 acquires GPS information (current position information) from the GPS receiver 51 (S125), and determines whether or not the vehicle 1 has moved into the second region based on the current position information ( S126). The second area can be determined as an area having a predetermined radius from the point based on position information corresponding to the work place indicated as work NO2 in the operation plan information recorded in the memory card 7. For example, in the example shown in FIG. 14, the second area may be determined as an area within a radius of 500 m from the point based on the position information of “XX Co., Ltd.” indicated as the work NO2 for the next loading operation. it can.

  Next, after determining that the vehicle 1 has moved into the second region, the CPU 20 acquires an ON / OFF signal from the ACC switch 57 (S127), and determines whether or not the signal has been changed from ON to OFF. (S128). That is, in S128, it is determined whether or not the crew member has operated the key cylinder to stop the engine.

  When the vehicle 1 moves into the second area (S126) and the engine is stopped (S128), the CPU 20 arrives at the second point (“XX Corporation” for loading). It is determined that it has been (S129).

  In the processing flow shown in FIG. 17, the departure and arrival of the vehicle 1 is determined based on the ON / OFF signal from the ACC switch 57 and the current position information from the GPS receiver 51, but the signal from the ACC switch 57 Instead of this, an ON / OFF signal from the IG switch 58 may be used. That is, the CPU 20 starts when the vehicle 1 moves out of the first area after receiving the ON signal from the IG switch 58, and turns off the IG switch 58 after the vehicle 1 moves into the second area. You may make it judge that it arrives after receiving.

  In the processing flow shown in FIG. 17, the departure and arrival of the vehicle 1 is determined based on the ON / OFF signal from the ACC switch 57 and the current position information from the GPS receiver 51, but the signal from the ACC switch 57 Instead of this, an open signal and a close signal from the door opening / closing sensor 54 may be used. That is, the CPU 20 starts when the vehicle 1 moves out of the first area after receiving the closing signal from the door opening / closing sensor 54, and after the vehicle 1 moves into the second area, The arrival may be determined after receiving the open signal.

  In the processing flow shown in FIG. 17, the departure and arrival of the vehicle 1 is determined based on the ON / OFF signal from the ACC switch 57 and the current position information from the GPS receiver 51, but the signal from the ACC switch 57 Instead of this, a wearing signal and a non-wearing signal from the seat belt sensor 55 may be used. That is, the CPU 20 starts when the vehicle 1 moves out of the first area after receiving the mounting signal from the seat belt sensor 55, and after the vehicle 1 moves into the second area, You may make it judge that it arrives after receiving a non-wearing signal.

  In the processing flow shown in FIG. 17, the departure and arrival of the vehicle 1 is determined based on the ON / OFF signal from the ACC switch 57 and the current position information from the GPS receiver 51, but the signal from the ACC switch 57 Instead of this, a seating signal and a non-sitting signal from the seating sensor 56 may be used. That is, the CPU 20 departs when the vehicle 1 moves out of the first area after receiving the seating signal from the seating sensor 56, and after the vehicle 1 moves into the second area, the non-seating from the seating sensor 56. You may make it judge that it arrives after receiving a signal.

  In the example described above, based on any one of the signals of the ACC switch 57, the IG switch 58, the door opening / closing sensor 54, the seat belt sensor 55, and the seating sensor 56, and the current position information from the GPS receiver, the vehicle 1 Although the departure and arrival are determined, the departure and arrival of the vehicle 1 can be determined only by any one or a combination of the ACC switch 57, the IG switch 58, the door opening / closing sensor 54, the seat belt sensor 55, and the seating sensor 56. A determination may be made. Further, the departure and arrival of the vehicle 1 may be determined based only on the current position information from the GPS receiver.

  Further, departure and arrival of the vehicle 1 may be determined using the vehicle speed based on the vehicle speed pulse from the vehicle speed sensor 53. That is, the CPU 20 determines “departure” when the vehicle speed changes from 0 km / h to 1 km / h, and “arrival” when the vehicle speed changes from a predetermined speed (for example, 10 km / h) to 0 km / h. Anyway.

  As described above, it is possible to reduce the operation load on the crew by automatically determining departure and arrival of the vehicle 1 in accordance with the processing flow shown in FIG. Note that the processing flow shown in FIG. 17 is repeatedly executed at predetermined intervals corresponding to all work places in the operation plan information.

  Next, after the operation is completed, the crew inserts the memory card 7 on which various information is recorded into the slot 404 of the playback device 400 and transfers the various information to the card information recording unit 409. The playback device 400 automatically creates a daily driving report based on the collected information (S104).

  18 to 20 are diagrams showing examples of daily driving reports.

  18 to 20 are display examples in which daily operation reports based on the operation plan information shown in FIG. Although it is divided into three screens in terms of configuration, it may be displayed on one screen.

The basic item display area 510 displays operation start date / time information, operation end date / time information, operation time, travel time, travel distance, work time, and break time. The operation start date / time information, the operation end date / time information, the operation time, the travel time, the travel distance, the work time, and the break time are input from the operation unit 12 of the terminal 10 by the crew and recorded in the fourth area 204 of the memory card 7. Information calculated based on the operation information.

  In the operation status display area 511, information based on the operation information corresponding to the operation plan information and input from the operation unit 12 of the terminal 10 by the crew member and recorded in the fourth area 204 of the memory card 7 is arranged. It is displayed. The travel distance is calculated by the CPU 20 based on the vehicle speed pulse, but may be determined based on other information (for example, GPS information).

  In the information display area 512, information regarding the number of cases for each of the three conditions for which the recording condition is satisfied and whether there is always recording is displayed in the current operation. In this example, by clicking the “speed trigger” portion 518 where the recording condition is satisfied in the information display area 512, the display screen is set to display the image information recorded when the recording condition is satisfied. . A display screen for displaying image information will be described later.

  In the violation item display area 513, the number of detections of the six violation items used for the above-described eco-safe driving diagnosis in the current operation is displayed. In the example of FIG. 18, “overspeed” and “idling” are detected twice, and the result that the number of times of detection of other items is 0 is displayed.

  The eco / safe driving diagnosis display area 514 displays the eco / safe driving diagnosis result. The evaluation score for diagnosing eco-safe driving was obtained by the regenerating device 400 by subtracting the score corresponding to the number of detections of each of the above-mentioned six violation items in this operation from 100 points. Is. In the example of FIG. 18, 2.5 points are deducted for each “overspeed” and “idling”, and a total of 10 points are deducted, with 90 points being evaluated. The rank can be, for example, “A” rank to “E” rank according to the evaluation score. The violation items for diagnosing eco-safe driving are not limited to the above six items, and a method for obtaining the evaluation score by calculation can be appropriately determined.

  The screen 520 shown in FIG. 19 is for returning to the simple basic matter display area 521, the driving result display area 522, the work result display area 523, the print instruction button 524, the next page instruction button 525, and the display screen 500 shown in FIG.
