Description

  The present invention relates to an operation plan change system and a drive recorder used in the operation change system.

  For example, a company or a local government that manages the operation of a route bus manages the bus so as to operate according to a predetermined operation plan. That is, according to a predetermined timetable (service schedule), each bus stop on the operation route stops at a time corresponding to the time displayed on the timetable, and accepts customers' getting on and off.

  On the other hand, a customer who wants to use a route bus can grasp the scheduled time when the route bus will arrive and depart from the target bus stop by referring to the contents of a predetermined timetable, and can get on the bus at the scheduled time. You will wait for the arrival of the bus at the target bus stop during the time.

  Accordingly, companies, local governments, and the like that operate route buses can obtain the trust of customers by operating route buses according to the contents of the timetable. However, in reality, there is a possibility that the operation will be different from the operation plan due to an inappropriate operation plan, the influence of traffic congestion, etc., or due to the mistake or omission of the bus crew (driver). is there. In addition, even when a route bus is actually operated according to the contents of the timetable, troubles may occur between the customer and the company due to misunderstanding of the customer or incorrect time recognition. possible.

  In recent years, a drive recorder has been used as an in-vehicle operation recording device that can be used to manage the operation state of a business vehicle such as a route bus. For example, the conventional drive recorder disclosed in Patent Document 1 has a function of continuously and continuously recording image data acquired by an in-vehicle camera.

JP 2012-3607 A

  When a drive recorder having a constant recording function as disclosed in Patent Document 1 is mounted on a route bus, a large amount of operation data such as images taken of the route bus operation is collected almost continuously. It can be stored in a recording medium. As for route bus operation data, generally, data collected during the past week or so is stored and recorded on a drive recorder mounted on the vehicle or on the office database. Is assumed.

  For example, a complaint such as “There was no bus at the target bus stop at the time displayed in the timetable” may be sent to a company or the like that manages a route bus from a customer. In this case, a company or the like is required to first confirm whether or not the content of the customer complaint is true.

  If the relevant route bus is equipped with a drive recorder, the operation data collected during the past week or so is saved, so the operation records the facts of the subject matter of the complaint. Data may also remain. In other words, by reading and analyzing the operation data, the manager can confirm whether the route bus pointed out by the customer as a complaint was not at the bus stop at the time indicated in the timetable. . In addition, when the content of the complaint is fact, it is possible to confirm under what circumstances the route bus was actually operated.

  However, operation data recorded by a drive recorder such as a drive recorder is recorded almost continuously evenly, unless a large acceleration is detected due to a traffic accident or the like. Therefore, the administrator who analyzes data must refer to a large amount of recorded operation data in order to find data of a part of the time zone corresponding to the complaint, and the analysis work is extremely burdensome. It gets bigger.

  In recent years, a drive recorder with improved convenience has been demanded.

In the operation plan change system having the above-described configuration (1-1), each drive recorder has a first change from the first waypoint when it is determined that the vehicle is located at the second waypoint at the scheduled time. Information for calculating the elapsed time for analysis, which is the elapsed time required to travel to the waypoint 2, is recorded. And in the terminal for analysis, based on the elapsed time for analysis calculated based on the information received from each drive recorder, the schedule from the first waypoint held on the analysis terminal side to the second waypoint The operation time is changed. Thereby, it is acquired when it is determined that the vehicle is located at the second waypoint at the scheduled time. That is, the vehicle is operating normally and a given waypoint (for example, a bus stop) at a given time. ) The scheduled operation time is changed using only the elapsed time acquired when the vehicle is located. Therefore, it is possible to change the scheduled operation time so as to be an appropriate time suitable for the actual operation. As a result, for example, when the driver's operation is evaluated using the scheduled operation time, the evaluation can be appropriately performed.
Alternatively, based on the changed scheduled operating time, the scheduled time to arrive at the second waypoint is changed, or the route from the first waypoint to the second waypoint is changed. (That is, the operation plan is changed). As a result, the changed operation plan becomes unreasonable, and the occurrence of a situation where it is impossible to arrive at the second waypoint at the scheduled arrival time is suppressed. If a new timetable (operation schedule) is set in accordance with the changed operation plan, the timetable can be easily operated according to the contents.
In the operation plan change system having the configuration (1-2), the operation plan is held on the analysis terminal side, and the second operation plan held on the analysis terminal side based on the analysis elapsed time. The scheduled time to arrive at the waypoint is changed. As a result, only the elapsed time acquired when the vehicle is operating normally and the vehicle is located at a predetermined waypoint at a predetermined time is used as master data held on the analysis terminal side. The planned time of the plan is changed. As a result, the changed operation plan becomes unreasonable, and the occurrence of a situation where it is impossible to arrive at the second waypoint at the scheduled arrival time is suppressed. If a new timetable (operation schedule) is set in accordance with the changed operation plan, the timetable can be easily operated according to the contents.
In the operation plan change system configured as described in (1-3) above, the operation recorded in at least one of the drive recorders after the scheduled time of the operation plan held on the analysis terminal side is changed. The plan is rewritten with the changed operation plan held on the analysis terminal side. Thereby, the operation plan referred in the drive recorder in which the said operation plan was rewritten can be changed so that it may become an appropriate operation plan suitable for an actual operation. Then, the drive recorder collects a new analysis elapsed time according to the changed operation plan, and the analysis terminal further changes the scheduled time of the operation plan based on the newly collected analysis elapsed time. . Thereafter, the operation plan recorded in at least one of the drive recorders is rewritten to an operation plan that has been further changed in the analysis terminal. If such a change of the operation plan is repeatedly performed, the operation plan can be made an optimum operation plan. As a result, the operation plan becomes unreasonable, and the occurrence of a situation where it is not possible to arrive at the second waypoint at the scheduled arrival time is suppressed. And if a new timetable (operation schedule) is set according to the said operation plan, it can be set as the timetable which is easy to operate a vehicle according to the content.

In the drive recorder having the configuration (2), it is determined whether or not the vehicle is located at a transit point (for example, a bus stop) corresponding to the scheduled time at the scheduled time determined by the operation plan. Thus, for example, when it is determined that the vehicle is not located at the waypoint at the scheduled time, an alarm sound is output to indicate that the vehicle could not be located at the waypoint at the scheduled time. The user can be notified to recognize the fact and prevent its recurrence.
Alternatively, by recording whether the vehicle is located at the waypoint at the scheduled time, it is possible to confirm after the operation whether the vehicle is located at the waypoint at the scheduled time.
Alternatively, by recording the image data acquired in the time zone including the time point when the vehicle is determined to be located at the waypoint at the scheduled time, the vehicle is located at the waypoint at the scheduled time. It can be proved by the image after the operation ends.
Further, in the always-recording type drive recorder, the first data set acquired by the in-vehicle camera in a time zone including a time point when it is determined that the vehicle is not located at the waypoint is a time zone other than the time zone. Are recorded so as to be identifiable as a set of image data different from the second set of data acquired in step S2. Thereby, image data recorded before and after the time point when it is determined that the vehicle is not located at a transit point (for example, a bus stop) is easily found out of a large amount of image data collected by the continuous recording process. . Therefore, an administrator who analyzes the collected data can easily find data in a time zone corresponding to the customer complaint from a large amount of recorded image data. As a result, the burden of analysis work can be reduced.
In the drive recorder having the above configuration ( 3 ), it is necessary to operate from the first waypoint to the second waypoint when it is determined that the vehicle is located at the second waypoint at the scheduled time. Information for calculating the elapsed time for analysis, which is the elapsed time, is recorded. Thus, for example, each time the vehicle travels from the first waypoint to the second waypoint, it is acquired when it is determined that the vehicle is located at the second waypoint at the scheduled time. Based on the information stored and recorded, the information obtained when the vehicle is operating normally and the vehicle is located at a predetermined transit point (for example, a bus stop) at a predetermined time Based on the calculated elapsed time for analysis, the estimated arrival time can be changed, or the operation route from the first waypoint to the second waypoint can be changed.
Alternatively, it is possible to evaluate each driver's operation or educate the driver based on the calculated elapsed time for analysis.
In the drive recorder having the configuration ( 4 ), an alarm is output when it is determined that the vehicle is not located at the waypoint. Accordingly, it is possible to notify a user such as a driver of the vehicle that the vehicle cannot be located at the scheduled time and to recognize the fact, and to prevent the recurrence.

And an office PC (Personal Computer) (analysis terminal, not shown).

  Each drive recorder 100 is mounted and used in a vehicle that operates according to a predetermined operation plan such as a route bus. Hereinafter, in this specification, an operation plan refers to a plan that defines a vehicle operation plan. For example, a route bus corresponds to a predetermined timetable (operation schedule) and is The bus stops at each bus stop (passage point) at a time corresponding to the scheduled time displayed in the timetable, and accepts customers' getting on and off.

  As a basic operation, the drive recorder 100 automatically collects data such as images continuously during operation of the vehicle and records it as operation data. In order to record the collected operation data, a removable recording medium such as a memory card is used. Actually, a memory card 118 in which various information including operation plan information, which will be described later, is called a crew card is prepared for each crew member (driver). The drive recorder 100 reads and writes data related to the operation of the vehicle using the crew card of the crew who operates the host vehicle.

  On the other hand, a management office PC (analysis terminal) (not shown) is installed in an office of a company or the like that manages vehicles such as route buses and crews operating the bus. The office PC in the office is composed of, for example, a general personal computer, a recording area for recording an operation plan for writing on the crew card, and a recording for recording various data collected by the drive recorder 100. And a memory (not shown) having a region. That is, the memory of the office PC functions as a fourth recording unit for recording the operation plan and a fifth recording unit for recording various data collected by the drive recorder 100. Further, the office PC can realize a predetermined function by executing an application program for managing the vehicle and the crew.

  More specifically, the management office PC has a function of creating or changing a vehicle operation plan, a function of writing data such as an operation route on each crew card according to the created operation plan, It has a function of reading and recording the operation data recorded from the crew card after the operation.

  The drive recorder 100 is loaded with a crew card (memory card 118) in which the operation plan is written in the office PC, and the drive recorder 100 executes various processes described later using the operation plan.

<Description of Configuration of Drive Recorder 100>
As shown in FIG. 1, the drive recorder 100 includes a microcomputer (CPU: Central Processing Unit) 111, interfaces (I / F) 112 to 114, 116, a contention data holding unit 115, an acceleration (G) sensor 117, a memory. A card (SD card) 118, a volatile storage unit (SDRAM: Synchronous Dynamic Random Access Memory) 119, and a monitor output unit 120 are provided.

  The microcomputer 111 is a control unit, and performs processing for realizing various functions of the drive recorder 100 by executing a program prepared in advance. For example, the operation shown in FIG. 5 is realized by the processing of the microcomputer 111. The microcomputer 111 has a built-in clock function for grasping the current time, and also functions as a time information acquisition unit for acquiring current time information.

  The interface 112 performs signal processing for connecting each output of the plurality of in-vehicle cameras 11 mounted on the vehicle to the microcomputer 111. Specifically, the video signal output from the in-vehicle camera 11 is quantized for each captured frame to generate digital image data, and further subjected to processing such as compression. The microcomputer 111 can acquire from the interface 112 image data of each frame obtained sequentially by photographing by the in-vehicle camera 11.

  The interface 113 performs signal processing necessary for connecting a GPS (Global Positioning System) receiver 12 mounted on the vehicle to the microcomputer 111. The GPS receiver 12 can receive radio waves arriving from a plurality of GPS satellites. Further, the current position (latitude / longitude) of the vehicle can be calculated based on reception times of radio waves received from a plurality of GPS satellites. That is, the interface 113 functions as a position information acquisition unit that acquires the current position information of the vehicle.

  The interface 114 performs signal processing necessary for connecting the vehicle speed sensor 13 to the microcomputer 111. The vehicle speed sensor 13 is mounted on the vehicle side and outputs a pulse signal called a vehicle speed pulse every time the vehicle moves a predetermined amount. In general, a sensor installed on the output shaft of a vehicle transmission outputs a pulse signal each time the output shaft rotates a predetermined amount. Therefore, by counting the vehicle speed pulses, the moving speed of the vehicle (vehicle speed: km / h) and the moving distance can be grasped. The interface 114 performs electrical processing such as waveform shaping of the input signal and adjustment of the pulse period.

  The contention data holding unit 115 is used to hold various data described later. The contention data holding unit 115 is configured by, for example, a nonvolatile memory that can freely read and write data.

  The acceleration sensor 117 has a function for detecting the value of acceleration applied in the longitudinal direction of the traveling direction of the vehicle. The acceleration sensor 117 is connected to the microcomputer 111 via the interface 116. The microcomputer 111 gives a signal representing the acceleration value detected by the acceleration sensor 117 to the microcomputer 111.

  The memory card 118 is an external storage medium, is detachably connected to the drive recorder 100, and can record various information such as image data. The memory card 118 is also detachably attached to the office PC. Thus, the drive recorder 100 according to the present embodiment transmits image data and the like to the external device via the memory card 118. When the drive recorder 100 is operated, the memory card 118 is connected to the drive recorder 100. As will be described later, the memory card 118 has a recording area for recording operation data including image data acquired by the in-vehicle camera 11, a recording area for recording an operation plan, and an elapsed time required for operation between bus stops. And a recording area for recording information including. That is, the memory card 118 functions as a first recording unit that records image data acquired by the in-vehicle camera 11, a function as a second recording unit that records operation plan information, and operation between bus stops. And a function as a third recording unit for recording information including the elapsed time required.

  The volatile storage unit 119 is configured by a volatile memory (SDRAM) that can freely read and write data by accessing the microcomputer 111. The volatile storage unit 119 is used for temporarily storing data.

  The monitor output unit 120 functions as an alarm output unit and includes an output unit for display and an output unit for audio output. The display output unit is used to output various information on the screen. Specifically, an image captured by the in-vehicle camera 11, information on the detected position, vehicle speed, acceleration, or a warning message regarding occurrence of an abnormality can be output on the screen. Further, the output unit for voice output can output a warning message or the like related to the occurrence of abnormality as pseudo-voice sound.

<Explanation of crew card creation>
An example of a procedure for creating a crew card (memory card 118) used by the drive recorder 100 is shown in FIG. A management office PC in the office executes the processing shown in FIG.

  When the office PC detects that the predetermined memory card 118 has been installed in step S101, the office PC reads operation data including image data collected by the drive recorder 100 in the next step S102 from the memory card 118, and Record in memory.

  In step S103, the stored contents of the card are initialized. Thereafter, in step S104, a crew card is created. More specifically, information such as an identification code of the corresponding crew member is written in the memory card 118. In addition, the office PC writes the data of the operation route of the vehicle that the corresponding crew member should operate on that day (that is, the operation plan) recorded in the memory in the crew card.

  Each crew member starts his / her operation after taking out his / her crew card created by the above procedure from the office PC and mounting it as the memory card 118 on the drive recorder 100 on the vehicle which operates on the day.

  Through the series of processes described above, the operation data collected by the drive recorder 100 and stored in the memory card 118 is recorded in the memory of the office PC, and the operation plan recorded in the memory of the office PC is stored in the memory card 118. To the drive recorder 100.

<Specific examples of service routes>
A specific example of the order of arrangement of a plurality of bus stops on one operation route is shown in FIG. Moreover, the structural example of the data of an operation route is shown in FIG.

  In the case of a regular route bus, as shown in FIG. 3, after starting the bus operation, after stopping at the first bus stop (A), which is the transit point of the operation route, and after getting on and off the customer Depart the bus stop (A) and head to the second bus stop (B). Stop at the second bus stop (B) again, and after the customers get on and off, leave the bus stop (B) and head for the third bus stop. Such operation is repeated and the operation of the day ends at the last bus stop (Z).

  Therefore, for example, in the case of an operation route that sequentially passes through N bus stops, data on the operation route (operation plan) as shown in FIG. 4 is written in the aforementioned crew card. In the example shown in FIG. 4, for each bus stop, data of position coordinates (latitude / longitude) Dpn indicating the position where the corresponding n-th bus stop exists and scheduled time Dtn for departing the corresponding bus stop are included. Yes. That is, the operation plan includes information associating each waypoint with a scheduled time at which the vehicle should be located at the waypoint. Here, the scheduled time Dtn is the departure time for each bus stop that matches the contents of the timetable published to the customer in advance.

<Description of Operation of Drive Recorder 100>
FIG. 5 shows main operations of the drive recorder 100 shown in FIG. When the microcomputer 111 in the drive recorder 100 executes a predetermined program, the operation shown in FIG. 5 is realized. The contents of each step in FIG. 5 will be described below.

  In step S11, the microcomputer 111 accesses the crew card attached to the drive recorder 100 as the memory card 118, and reads the operation route data (operation plan, see FIG. 4) held in this card.

  In step S12, the microcomputer 111 starts a normal operation data recording operation. That is, image data of images taken by the in-vehicle camera 11 is acquired almost continuously or periodically from the interface 112, and sequentially stored in a predetermined storage area secured on the memory card 118 as a time-series data group. Store. Further, information on the current position (latitude / longitude), information on the current vehicle speed, information on the current acceleration, information on the current time, and the like are periodically collected and recorded on the memory card 118.

  Information on the current position (latitude / longitude) of the vehicle is obtained as an output of the GPS receiver 12. The vehicle speed information can be calculated based on a vehicle speed pulse signal output from the vehicle speed sensor 13. The acceleration information can be acquired based on a signal output from the acceleration sensor 117. The microcomputer 111 always knows the current time information.

  In step S13, the microcomputer 111 initializes an internal counter Cn indicating the number of data of the bus stop that should be referred to currently in the operation route. That is, “1” is stored in the internal counter Cn in order to refer to the data of the first bus stop first.

  In step S14, the microcomputer 111 reads the nth bus stop data Dn from the operation route data read in S11 according to the current value (n) of the internal counter Cn. For example, when the value (n) of the internal counter Cn is “1”, the position coordinate Dp1 of the first bus stop shown in FIG. 4 and the scheduled time Dt1 for departure from the corresponding bus stop are read.

  In step S15, the microcomputer 111 acquires the latest information regarding the current position Pc, the vehicle speed Vc, and the current time of the host vehicle.

  In step S16, the microcomputer 111 identifies whether or not the host vehicle (route bus) is stopped. More specifically, it is considered that the vehicle is stopped when the value of the vehicle speed Vc acquired in S15 is smaller than a predetermined threshold value, and it is considered that the vehicle is traveling when the vehicle speed Vc exceeds the threshold value. When it is detected that the vehicle is stopped, the process proceeds from S16 to the next process of S17.

  In step S17, the microcomputer 111 compares the current position Pc of the host vehicle with the position (Dpn) of the data Dn of the nth target bus stop in the operation route. If it is stopped near the target bus stop, the process proceeds from S17 to S19, and if it is not close to the target bus stop, the process proceeds to S20.

  In step S18, the microcomputer 111 records the arrival time and the stop time. As for the arrival time, the time when the vehicle speed Vc first falls below the threshold value after the current position Pc of the host vehicle reaches the vicinity of the corresponding nth bus stop is recorded. As for the stop time, the elapsed time from when the arrival time is recorded until the present time is recorded while being sequentially updated until the vehicle departs.

  In step S19, the microcomputer 111 identifies whether or not the host vehicle has stopped at the nth target bus stop until the scheduled departure time. That is, the latest change in the vehicle speed Vc is monitored to determine the presence or absence of departure (Vc> 0 km / h), and the scheduled departure time Dtn in the target bus stop data Dn is compared with the current time. If it is detected that the vehicle has stopped until the scheduled departure time Dtn, the process proceeds from S19 to S21. If the departure is detected before the scheduled departure time Dtn, the process proceeds to S22.

  The state proceeding from S19 to S21 is a normal operation state, and means that the corresponding route bus was present at the target bus stop at the scheduled time displayed in the timetable.

  On the other hand, the state proceeding from S19 to S22 is an abnormal operation state. That is, since the corresponding route bus does not exist at the target bus stop at the scheduled time displayed in the timetable, there is a possibility that a customer who has planned to board at the corresponding bus stop cannot get on the bus. Therefore, there is a possibility that a crew member may make a mistake in operation, and a customer may make a complaint to a company that operates a bus.

  In step S20, the microcomputer 111 compares the current position Pc in the stopped state with the positions (latitude / longitude) of other bus stops other than the nth target bus stop. The “other bus stop” is a bus stop other than the nth bus that exists on the operation route. When the vehicle stops at a bus stop other than the nth target bus stop, the process proceeds from S20 to S22. If the vehicle is not at a bus stop, the process returns to S15.

  The state of proceeding from S20 to S22 is an abnormal operation state and corresponds to a case where the vehicle passes by without stopping at any of the bus stops existing on the operation route. Therefore, there is a possibility that a crew member may make a mistake in operation, and a customer may make a complaint to a company that operates a bus.

  In step S <b> 21, the microcomputer 111 records data indicating that the route bus is operating normally at the n-th target bus stop on the memory card 118. Specifically, a “normal flag” is added to the operation data (image data etc.) recorded in the time zone before and after the scheduled departure time Dtn so that it can be distinguished from the data recorded in other time zones. To the memory card 118. Further, the operation data recorded in the corresponding time zone and the added normal flag are also recorded in a special area, for example, the contention data holding unit 115.

  In step S22, the microcomputer 111 records in the memory card 118 data indicating that the route bus is operating abnormally at the nth target bus stop. Specifically, an “abnormal flag” is added to the operation data (image data, etc.) recorded in the time zone before and after the scheduled departure time Dtn so that it can be distinguished from the data recorded in other time zones. To the memory card 118. In addition, the operation data recorded in the corresponding time zone and the added abnormality flag are also recorded in a special area, for example, the contention data holding unit 115.

  In step S23, the microcomputer 111 counts up the value (n) of the internal counter Cn so that the next bus stop data can be referred to.

  In step S24, the microcomputer 111 compares the value (n) of the internal counter Cn with the number (N) of the last bus stop to identify whether or not the operation up to the last bus stop has ended. If the operation has not ended, the process returns to S14 and the above-described processing is repeated.

  In step S25, since abnormal operation is detected, the microcomputer 111 controls the monitor output unit 120 to output a warning by sound and call a predetermined display screen in order to alert the crew. Display a warning above.

A configuration example of data recorded on the memory card 118 by the drive recorder 100 is shown in FIG. Normal operation data such as image data is sequentially recorded on the memory card 118 as almost continuous time-series data. The data shown in FIG. 6 represents only the operation data recorded in the vicinity of the bus stop among the large amount of operation data recorded on the memory card 118. That is, the same data as the data is recorded in the contention data holding unit 115.

  Each of the M pieces of operation record data Dr1 to DrM shown in FIG. 6 includes time, current position, vehicle speed, image data, and operation state data. As for the operation state data, there are a normal flag F1 and abnormal flags F2 and F3. The normal flag F1 is a flag added in step S21 in FIG. The abnormality flag F2 is a flag added in S22 when a time abnormality is detected in step S19 of FIG. 5, and the abnormality flag F3 is a case of detecting an error in the bus stop that stops in step S20 of FIG. Is a flag added in S22.

  In the data shown in FIG. 6, the normal flag F1 is added to the operation record data (Dr1 to Dr4, DrM) of the 1st to 4th bus stops and the Mth bus stop, but the 5th and 6th bus stops. Abnormal flags F2 and F3 are respectively added to the bus stop operation record data (Dr5 and Dr6). Therefore, it can be easily confirmed from this data that the abnormal operation was performed near the fifth and sixth bus stops.

  Therefore, when analyzing a large amount of operation data recorded on the memory card 118 with the office PC on the office side, it was recorded when passing near the bus stop by searching for normal flags and abnormal flags. Operation data can be extracted easily. That is, a set of image data acquired in a time zone including a time point when it is determined that the vehicle is not located at the target bus stop, and a set of image data to which the abnormality flag F2 or the abnormality flag F3 is added (first (Data set) is recorded so as to be identifiable as data different from the set of image data (second data set) acquired in a time zone other than the time zone and to which the normal flag F1 is added.

<Processing for scheduled operation time change>
A specific example of the processing procedure for changing the scheduled operation time is shown in FIG. The office PC arranged in the office of a company or the like that manages the operation of the route bus implements the operation shown in FIG. 7 by executing a program for changing the operation plan.

  Moreover, the specific example of the information used for scheduled operation time change is shown in FIG. That is, the office PC changes the operation plan based on the information shown in FIG.

  First, before showing the details of the specific processing in each step of the operation shown in FIG. 7, the data recorded in the memory of the office PC at the time when the processing is executed will be described.

  In the office PC memory, the operation data collected by the drive recorder 100 by the process shown in FIG. 5 is transmitted and recorded via the crew card (memory card 118) by the process shown in FIG. ing. More specifically, operation data collected by a plurality of drive recorders is collectively stored in the memory of the office PC as an operation record database DB01 expressed in a database format. By repeating the data reading from a plurality of crew cards every day after the daily operation or periodically, the daily operation record data of each crew member or the daily operation record for each vehicle is stored on the operation record database DB01. Data is accumulated and recorded sequentially. And in office PC, operation information is changed using the data recorded on the said operation record database DB01.

  Further, the current operation plan of the route bus is held in the operation plan database DB02 in the memory of the office PC. In this operation plan database DB02, the scheduled operation time from each bus stop to the bus stop to be reached next is also held.

Specific processing contents in each step shown in FIG. 7 will be described.
The office PC that has received an operation for starting the change of the operation plan by the administrator executes the process of step S51.

  In step S51, the office PC searches the operation data registered in the operation record database DB01, and from the specific bus stop A (first waypoint) designated by the administrator's operation, next to the bus stop A. The operation data regarding the operation in the designated time zone to the bus stop B (second waypoint) to be reached is extracted.

  In step S52, the office PC determines the first bus stop arrival time T1a, the bus stop stop time (length) T1b, the second bus stop arrival time T2a, and the operation record for each date based on the operation data extracted in S51. Data for analysis in which four pieces of time information of the bus traveling time T12 are associated is created.

  Here, the first bus stop arrival time T1a and the second bus stop arrival time T2a correspond to the arrival time detected in S18 of FIG. 5, and the bus stop stop time T1b corresponds to the stop time detected in S18. In addition, the bus-to-bus operation required time T12 represents an elapsed time from the time when the vehicle leaves the bus stop A to the time (T2a) when the vehicle arrives at the bus stop B. These time information can be obtained by extracting from the operation data or by calculating the contents of the operation record data.

  Therefore, as shown in FIG. 8, analysis data including four types of time information (T1a, T1b, T2a, T12) can be created in S52. In the example shown in FIG. 8, for each day of the month from August 9th to September 8th, based on the operation record data recorded in the time zone around 10 am, a specific “ It is assumed that data for analysis related to the operation between “bus stop A” and the next “bus stop B” is created.

  In step S53, the office PC follows the flags (corresponding to F1, F2, and F3 in FIG. 6) added to the operation data extracted in S52, the operation data including the influence of the operation error, and the operation error. Information Df for distinguishing operation data not including influence is added to the analysis data as shown in FIG.

In step S54, the office PC calculates only the average operation time T12M (elapsed time for analysis) by summing up only the operation data with no driving errors in the analysis data created in S53.
For example, in the example shown in FIG. 8, since the information Df of the data on August 12 is “present”, the data on August 12 is excluded, and T12M is an average value obtained by summing up the required times T12 for other dates. (15 minutes) is calculated.

In step S55, the office PC changes the scheduled operation time between the bus stops A and B held in the operation plan database DB02 to the average operation required time T12M calculated in step S54.
For example, in the example shown in FIG. 8, the calculated average operation required time T12M is 15 minutes, and the scheduled operation time between “bus stop A” and “bus stop B” in the current operation plan (operation schedule) is 13 Minutes. In this case, it is determined that the operation schedule needs to be reviewed for 2 minutes, which is the difference between 15 minutes and 13 minutes, and the scheduled operation time is changed to 15 minutes. At this time, when calculating the average operation required time T12M, the operation data including the influence of the operation error is excluded in advance (S54). Judgment can be made.

In step S56, the office PC stores only the value of the difference between the scheduled operation time before the change and the scheduled operation time after the change (that is, the calculated average operation required time T12M) in the operation plan database DB02. The scheduled departure time of bus stop B (corresponding to Dtn in FIG. 4) is changed.
For example, in the example shown in FIG. 8, the scheduled operation time before the change is 13 minutes, and the scheduled operation time after the change is 15 minutes. In this case, it is determined that it is necessary to review the scheduled departure time of the bus stop B by 2 minutes, which is the difference between 15 minutes and 13 minutes, and the scheduled departure time of the bus stop B is delayed by 2 minutes.

  Based on the operation data collected by the plurality of drive recorders 100 by the series of processes described above, the scheduled operation time from the bus stop A to the bus stop B held in the office PC and the departure of the bus stop B in the operation plan The scheduled time is changed.

  Further, when the crew card creation process shown in FIG. 2 is executed after the operation plan held in the office PC is changed by the above process, in step S104, the changed operation plan is executed. Is written in the memory card 118. Then, the next operation is started with the memory card 118 mounted in the drive recorder 100. That is, the next operation is started in a state in which the operation plan held by each drive recorder 100 is changed to the changed operation plan held in the office PC. In this case, it is not necessary to rewrite all the operation plans of the drive recorder 100 included in the operation plan change system according to the present embodiment, and only the operation plans of some drive recorders 100 of the drive recorders 100 are included. A configuration that can be rewritten may be used.

  Below, the operation plan change system which concerns on this embodiment, and the effect | action and effect of the drive recorder 100 are demonstrated.

The operation plan change system according to the present embodiment is used by being mounted on a vehicle, and includes a plurality of drive recorders 100 that record image data acquired by the in-vehicle camera 11 on a memory card 118, and the plurality of drive recorders 100. An operation plan change system including an office PC (analysis terminal) capable of transmitting and receiving information. Each drive recorder 100 should reach the microcomputer 111 that acquires the current time information, the interface 113 that acquires the current position information of the vehicle, the bus stop A (first waypoint), and the bus stop A. A memory card 118 that records an operation plan representing the bus stop B (second waypoint) and the scheduled departure time of the bus stop B, and an operation required time T12 between the bus stops (from the time when the vehicle departs the bus stop A to the bus stop B And a memory card 118 for recording information for calculating (elapsed time until the vehicle arrives), and at the scheduled departure time based on the time information, the position information, and the operation plan. It is determined whether or not the vehicle is located. As a result of the determination, it is determined that the vehicle is located at the bus stop B at the scheduled departure time. Information for calculating serial elapsed time at which the average travel time required T12M (the elapsed time for analysis) is recorded in the memory card 118. The office PC (analysis terminal) records in the memory (operation plan database DB02) in which the scheduled operation time from bus stop A to bus stop B is recorded, and in the memory card 118 of each drive recorder 100 received from each drive recorder 100. And a memory (operation record database DB01) for recording information for calculating the calculated average operation time T12M, and recorded on the memory card 118 based on the calculated average operation time T12M. Scheduled operation time is changed.
This is obtained when it is determined that the vehicle is located at the bus stop B at the scheduled time, that is, when the vehicle is operating normally and the vehicle is located at the predetermined bus stop at the predetermined time. The scheduled operation time is changed using only the acquired elapsed time. Therefore, it is possible to change the scheduled operation time so as to be an appropriate time suitable for the actual operation. As a result, for example, when the driver's operation is evaluated using the scheduled operation time, the evaluation can be appropriately performed.
Therefore, according to the operation plan change system which concerns on this embodiment, the operation plan change system which improved more convenience can be provided.

In the operation plan change system according to the present embodiment, the operation plan is recorded in the memory (operation plan database DB02) of the office PC, and is recorded in the operation plan database DB02 based on the elapsed time for analysis. The scheduled time of the operation plan is changed.
As a result, only the elapsed time acquired when the vehicle is operating normally and the vehicle is located at a predetermined waypoint at a predetermined time is used as master data held on the analysis terminal side. The planned time of the plan is changed. As a result, the changed operation plan becomes unreasonable, and the occurrence of a situation where it cannot arrive at the bus stop B at the scheduled arrival time is suppressed. If a new timetable (operation schedule) is set in accordance with the changed operation plan, the timetable can be easily operated according to the contents.

In the operation plan change system according to the present embodiment, after the scheduled time is changed, the operation plan recorded in the memory card 118 of each drive recorder 100 is rewritten with the operation plan recorded in the operation plan database DB02. It is done.
Thereby, the operation plan referred in the drive recorder in which the said operation plan was rewritten can be changed so that it may become an appropriate operation plan suitable for an actual operation. Then, the drive recorder collects a new analysis elapsed time according to the changed operation plan, and the analysis terminal further changes the scheduled time of the operation plan based on the newly collected analysis elapsed time. . Thereafter, the operation plan recorded in at least one of the drive recorders is rewritten to an operation plan that has been further changed in the analysis terminal. If such a change of the operation plan is repeatedly performed, the operation plan can be made an optimum operation plan. As a result, the operation plan becomes unreasonable, and the occurrence of a situation where it is not possible to arrive at the second waypoint at the scheduled arrival time is suppressed. And if a new timetable (operation schedule) is set according to the said operation plan, it can be set as the timetable which is easy to operate a vehicle according to the content.

The drive recorder 100 according to the present embodiment is a drive recorder that is mounted on a vehicle and used to record image data acquired by the in-vehicle camera 11 in a memory card 118 (first recording unit). The drive recorder 100 includes a microcomputer 111 (time information acquisition unit) that acquires current time information, an interface 113 (position information acquisition unit) that acquires current position information of the vehicle, and the position coordinates of a bus stop (route point). And a memory card 118 (second recording unit) that records an operation plan in which Dpn and a scheduled time Dtn (scheduled time at which the vehicle should be located) departing from the bus stop are recorded. Then, based on the time information, the position information, and the operation plan, it is determined whether or not the vehicle is located at the position coordinate Dpn corresponding to the scheduled time Dtn at the scheduled time Dtn.
Thereby, for example, when it is determined that the vehicle is not located at the target bus stop at the predetermined scheduled time, the alarm sound is output, so that the vehicle cannot be positioned at the target bus stop at the predetermined scheduled time. This can be notified to the user such as the driver of the vehicle so that the fact can be recognized and the recurrence can be prevented.
Alternatively, by recording whether or not the vehicle is located at the target bus stop at the predetermined scheduled time, it is possible to determine whether or not the vehicle is located at the target bus stop at the predetermined scheduled time. I can confirm.
Alternatively, by recording image data acquired in a time zone including a time point when it is determined that the vehicle is located at the target bus stop at the predetermined scheduled time, the vehicle at the target bus stop at the predetermined scheduled time. It can be proved by the image after the operation is completed.
Therefore, according to the drive recorder 100 according to the present embodiment, a drive recorder with improved convenience can be provided.

The drive recorder 100 according to the present embodiment is a drive recorder that constantly records image data on the memory card 118. In the drive recorder 100, the first data set is a set of image data acquired by the in-vehicle camera 11 in a time zone including a time point when it is determined that the vehicle is not located at the position coordinate Dpn at the scheduled time Dtn. The second data set acquired in a time zone other than the time zone is recorded as identifiable data.
As a result, it is easy to find image data recorded before and after the time point when it is determined that the vehicle is not located at the target bus stop at a predetermined scheduled time from a large amount of image data collected by the continuous recording process. . Therefore, an administrator who analyzes the collected data can easily find data in a time zone corresponding to the customer complaint from a large amount of recorded image data. As a result, the burden of analysis work can be reduced.

Further, in the drive recorder 100 according to the present embodiment, the first stop point (bus stop A) among the route points should be reached next to the bus stop A among the route points. It further includes a memory card 118 that records information for calculating an elapsed time (time required for operation between bus stops T12) until the vehicle reaches the second waypoint (bus stop B). Information for calculating the average required travel time T12M (elapsed time for analysis), which is the elapsed time when it is determined that the vehicle is located at the bus stop B at the scheduled departure time, is recorded in the memory card 118.
Thus, for example, every time the bus stops from bus stop A to bus stop B, it is acquired when it is determined that the vehicle is located at bus stop B at the scheduled time. The information acquired when the vehicle is located at a predetermined bus stop at the time is accumulated and recorded, and the estimated arrival time is calculated based on the elapsed time for analysis calculated based on the accumulated and recorded information. It is possible to change or change the operation route from bus stop A to bus stop B.
Alternatively, it is possible to evaluate each driver's operation or educate the driver based on the calculated elapsed time for analysis.

The drive recorder 100 according to the present embodiment further includes a monitor output unit 120 (alarm output unit) that outputs an alarm. When it is determined that the vehicle is not located at the position coordinate Dpn at the scheduled time Dtn, the monitor output unit 120 outputs an alarm.
Accordingly, it is possible to notify a user such as a driver of the vehicle that the vehicle cannot be located at the target bus stop at a predetermined scheduled time so that the fact is recognized and the recurrence can be prevented.

  The technical scope of the present invention is not limited to the embodiment described above. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, in the present embodiment, the memory card 118 has a configuration in which the departure time Dtn for departure from each bus stop is recorded as the scheduled time to be located at the bus stop as a waypoint, as shown in FIG. Instead of the departure time, the arrival time at each bus stop may be recorded.

  Further, the drive recorder 100 according to the present embodiment is configured to automatically collect data such as images continuously during the operation of the vehicle and constantly record the data as operation data. As a recording trigger (that is, a recording start condition), image data acquired in time zones before and after the time when the recording trigger occurs may be recorded. Also with this configuration, it is possible to collect useful operation data for changing the operation plan.

  Moreover, in this embodiment, as shown in FIG. 8, about every day for one month from August 9 to September 8, based on the operation record data recorded at the time zone around 10:00 am, The case where the analysis data regarding the operation between a specific “bus stop A” and the next “bus stop B” on the operation route has been created has been described. It is not restricted to this example. For example, it may be based on data including all time zones of the day, or may be based on data collected on each Monday of the year.

  Further, in this embodiment, as in steps S21 and S22 of FIG. 5, by adding a flag to the corresponding data, operation data indicating normal operation status and operation data indicating abnormal operation status are added. However, even if a flag is not added, only relevant special data is extracted and recorded in a location different from the main body of the operation data (for example, the contention data holding unit 115). It does not matter as a configuration to keep. In addition, for data for managing operation data indicating normal operation status and operation data indicating abnormal operation status, information indicating the recording time zone of the corresponding operation data, recorded location (folder, etc.) A configuration in which a memory address or the like is recorded may be used.

  In the present embodiment, the memory card 118 and the memory (operation record database DB01) of the office PC include the first bus stop arrival time T1a, the bus stop stop time (length) T1b, the second bus stop arrival time T2a, and the bus stop. It is configured to record four pieces of time information of the required travel time T12, but is configured to record information for calculating the elapsed time from the time when the vehicle departs the bus stop A to the time when the vehicle arrives at the bus stop B. For example, the elapsed time itself may be recorded.

  In this embodiment, in step S56 in FIG. 7, the office PC determines the bus stop held in the operation plan database DB02 by the difference between the scheduled operation time before the change and the scheduled operation time after the change. Although it was set as the structure which changes the departure time of B, the structure which does not implement the said change may be sufficient. Also by the said structure, when the driver | operator's operation is evaluated using the said scheduled operation time, for example, there exists an effect that the said evaluation can be implemented appropriately.

  In this embodiment, in step S56 in FIG. 7, the office PC determines the bus stop held in the operation plan database DB02 by the difference between the scheduled operation time before the change and the scheduled operation time after the change. Although it was set as the structure which changes the departure time of B (namely, an operation plan is changed), it is good also as a structure by which an operation plan is changed by this other method. For example, the departure time and scheduled stop time of the bus stop A may be changed, or the operation route from the bus stop A to the bus stop B may be changed.

  In the present embodiment, when the crew card creation process shown in FIG. 2 is executed after the operation plan held in the office PC is changed, in step S104, after the change is made. Although the operation plan is written in the memory card 118, the operation plan in the memory card 118 may not be rewritten. Even with this configuration, the operation plan can be changed to a reasonable one.

  In the present embodiment, the operation plan change system is configured to include a plurality of drive recorders 100 that record image data acquired by the in-vehicle camera 11, but may be configured to include at least one drive recorder 100. For example, a configuration including only a single drive recorder 100 may be employed.
