Description

  The present invention relates to a video management system for managing an image obtained by photographing a scene condition at the time of a collection operation in a refuse collection vehicle that patrols and collects household waste and the like.

  As conventional techniques related to such a video management system, those described in Patent Documents 1 to 3 are known.

  In Patent Document 1, a waste storage box mounted on a vehicle body and having a rear opening, and a rear opening of the waste storage box are continuously provided, and has an input port for dust and is input from the input port. What is claimed is: 1. A waste collection vehicle comprising: a waste loading box equipped with a waste loading device for loading waste into the waste storage box through the rear opening; (a) a rear camera for photographing the vicinity and the rear of the waste entry port; (B) a front camera for shooting the front of the vehicle body, (c) a rear microphone installed near the rear camera, (d) a monitor for displaying an image, and (e) a drive recorder for recording the image. (F) There is described a dust collection vehicle having a video signal of a front camera and a rear camera and a control box for outputting the input video signal to a monitor and a drive recorder.

  In this dust collection vehicle, images taken by the front camera and the rear camera are recorded on the drive recorder and displayed on the monitor through the control box. In the drive recorder, it is possible to record an image on an external storage device such as a USB memory as in the case that is generally used widely (Patent Document 1 specification [0019]). The external storage device is removed from the drive recorder, brought back to the office, connected to the computer equipment of the office, and read out (the same [0024]). Then, the image recorded on the drive recorder can be used later for the trouble in collecting dust and the safety management of the workers (image [0022], [0024]). It is also described that a side camera may be installed to ensure the safety of workers (Same [0033]).

  Patent Document 2 discloses a waste information collecting apparatus provided in a waste collection vehicle having a configuration in which a packer unit for collecting waste is driven by power take-off, and provided in the packer unit to photograph the side of the vehicle Camera (7), position recognition means (GPS antenna 6) for recognizing the current position, image storage means (image memory 11) for storing an image taken by the camera, and power take-off switch for switching to power take-off When turned on, the camera transmits an imaging timing signal to the camera, and the in-vehicle unit stores the image photographed by the camera and the current position information recognized by the position recognition unit as waste information in the image storage unit An object information collection device is described.

  In this waste information collecting apparatus, when the packer unit of the vehicle is stopped at the collection place to collect the waste, the camera can photograph the collection place. Here, when the power take-off switch is turned on by the operator for waste collection, the on-vehicle device causes the camera to photograph a state immediately before collection of waste collected at the collection location, and the current position is the image information. It is stored in the image storage means with the information added. This makes it possible to reliably capture the waste discharge state for each waste collection location and to identify the location from the position information. In this way, it is possible to have the residents objectively recognize the amount of waste discharged to that area by estimating and comparing the amount of discharge for each waste collection location, and waste in comparison with other areas It is possible to raise awareness for the reduction of H. (Patent Document 2 specification [0006]).

  According to Patent Document 3, after arrival at each treatment site, an image of loading or unloading of waste on each waste transport vehicle acquired by an imaging unit (digital camera) of a mobile terminal (mobile phone (smartphone) or the like) A waste processing management system is described that automatically transmits data from a terminal to a server by an automatic image transmission unit immediately after imaging, and measures a vehicle by a global positioning unit (GPS or the like) of a portable terminal.

  In this way, it is possible to track and manage the disposal status of waste from plural types of information including images, and to prevent falsification of image data before transmission to the server.

  By the way, at the site of patrol collection by actual garbage collection vehicles, garbage is illegally taken out on a date other than the date of garbage ejection set in advance for each garbage station (home garbage collection place), or predetermined for each garbage station It is often seen that other types of waste (for example, “burning waste”, “resource waste”, “bottles”, etc.) are illegally taken to the waste station. In such a case, the waste collection company or the local government can not collect the waste according to a defined rule, and there are many cases where troubles occur between the residents around the waste station and the waste collection company or the local government. In particular, in the case where the waste is taken out to the waste station outside the specified time, there are many cases where it becomes a problem over the fact that the waste has been taken out.

  Therefore, there is a strong demand for a system capable of collecting and managing a video of the site situation at the time of collection work in a waste collection company or a local government. In the waste collection vehicle of Patent Document 1, the rear camera captures the vicinity and the rear of the waste inlet, records the image on the external storage device of the drive recorder, takes it back to the office, and returns it to the office computer equipment. By connecting and reading out, it is possible to collect and manage an image of the field situation at the time of collection work. In the waste disposal management system of Patent Document 3, an image of the site situation at the time of collection work is taken by the imaging means (digital camera) of the portable terminal possessed by the worker, and GPS position information is added to this to automatically By automatically transmitting from the terminal to the server by the image transmission means, it is possible to collect and manage the video of the site situation at the time of the collection operation.

  However, at the site of patrol collection by a real garbage collection vehicle, a worker needs to patrol many garbage stations in a short time and perform garbage collection promptly. In fact, there are many cases in which a worker works while moving and running in parallel with a waste collection vehicle between waste stations. Therefore, as in the case of the waste disposal management system of Patent Document 3, photographing a single garbage station with a portable terminal imposes a heavy workload on the worker, leading to a delay in working time. Also, as described in Patent Document 1, when the video taken by the drive recorder is brought back to the office, connected to the computer equipment of the office, read out, and managed by the computer equipment of the office, collection of waste is entrusted from the local government. Each dust collection company needs to introduce and manage a computer device for management, and the cost burden on the installation and maintenance of the equipment becomes large. In fact, most of the images obtained by photographing the site conditions at the time of collection work become unnecessary data not related to troubles and the like, so collecting and managing all of them is a waste of equipment. In addition, it is necessary to take the external storage device back to the office one by one, connect to the computer device in the office and read it out, which takes time and effort and makes management mistakes (mistakes for reading work, management information (photographing It is easy to make mistakes, etc.) of incorrect input of date and time. In addition, it is assumed that it is impossible to respond promptly to troubles because necessary video data can not be extracted until the refuse collection vehicle returns to the office.

  Therefore, the object of the present invention is that the operator does not have to bear the burden when photographing the field conditions at the time of collection work, and it is easily introduced without the burden of the cost of equipment introduction and maintenance of each waste collection company. It is an object of the present invention to provide an image management system in a dust collection vehicle which can reduce unnecessary work waste such as excessive collection of unnecessary data as much as possible.

Then, after confirmation, by double-clicking the mouse at the cursor position (or double-taping the touch panel), it is possible to specify a traveling course, an operating car, and a position on the course where the video to be browsed is photographed. The operation locus distribution unit 16 of the management server 1 performs the display change operation and the necessary data extraction / transmission operation at the time of the operation of the “operation history browsing website”.

  In the "home page for operation history browsing" of FIG. 7 (c), when the traveling course, operation vehicle and passing time at which the image to be browsed is photographed by the operator are designated (S305), the trajectory range designation unit of the client computer 2 22 designates the designated position on the traveling course as "trajectory range designation information". Further, the information of the operation vehicle designated by the operator is referred to as "vehicle designation information". Then, the trajectory range designation unit 22 transmits the “time zone designation information” and the “vehicle designation information” to the management server 1 together with the “recorded video distribution request” for requesting the distribution of the recorded video (S306) ).

  In the management server 1, when the "recorded image distribution request", "locus range designation information" and "vehicle designation information" sent from the client computer 2 are received (S404), first, the operation time zone calculation unit 17 With reference to the operation history table of the operation history database (see FIG. 4 (a)), the passing time of the operation vehicle at the position on the traveling course specified by the “trajectory range designation information” is calculated and calculated A fixed time range before and after the time is calculated as "time zone designation information" (S405). Next, the designated time zone video request unit 10 calculates the “time zone” calculated for the DR communication module 5 of the dust collection vehicle C (hereinafter referred to as “specific dust collection vehicle”) specified by the “vehicle specification information”. The designation information is transmitted together with the "recording video transmission request" for requesting transmission of the recording video (S406).

  When the DR communication module 5 of the specified refuse collection vehicle receives the “Recorded video transmission request” and the “time zone designation information” sent from the management server 1 (S501), the designated recorded video transmission unit 31 transmits the drive recorder 4 Among the video data stored in the external storage device 4a, the video data captured in the time zone specified by the "time zone specification information" is extracted (S502). Then, the extracted video data is transmitted to the management server 1 (S503). In the drive recorder 4 of the specified refuse collection vehicle, the video data captured by the plurality of on-vehicle cameras 3 (the on-vehicle cameras 3 at the front, side, and rear) are stored. The photographed video data is transmitted to the management server 1.

  When the management server 1 receives video data (hereinafter referred to as “acquired recording data”) sent from the DR communication module 5 of the specified refuse collection vehicle in response to the “recording video transmission request” transmitted earlier (S407) The received video storage unit 11 stores the acquired video recording data as a video file in the server storage unit 1a and registers the video file in the video management table of the video management database (see FIG. 4B) (S408). ). At the time of this registration, the "operation car ID" is specified by the "vehicle specification information", the operation car ID of the specified garbage collection vehicle, the "image start time" and the "image end time" are specified by the "time zone specification information" Start time and end time are registered. Next, the recorded video distribution unit 12 distributes the acquired recorded data via the communication line 7 to the client computer 2 that has transmitted the "recorded video distribution request" in step S306 (S409). Here, delivery of the acquired video recording data is performed by streaming delivery or download delivery according to an instruction from the client computer 2.

  When the client computer 2 receives the acquired recording data distributed from the management server 1, the video browsing unit 23 reproduces the acquired recording data and displays it on the display as shown in FIG. S307). In addition, since acquired video recording data is a video image | photographed with several vehicle-mounted camera 3 (vehicle-mounted camera 3 of the front, the side, the back), as shown in FIG.7 (d), The images taken by the respective on-vehicle cameras 3 are reproduced separately.

  As described above, only the video data requested by the operator of the waste collection operation center is taken out from the drive recorder 4 mounted on each waste collection vehicle C through the communication line in response to the request, and is sent to the waste collection operation center By distributing, it is possible to minimize work / hardware waste such as excessive collection and management of unnecessary video data. Moreover, since only necessary video data is transmitted from the drive recorder 4 to the management server 1, communication time and communication cost can be minimized. In addition, since the data center collectively manages acquisition and storage of video data of each dust collection operation center, each dust collection operation center does not need to introduce a system for independently managing video data. The burden of equipment cost and management cost in introducing the system is small, and the video management system can be easily introduced. In addition, since the shooting of the video data is continuously shot during the engine activation of the refuse collection vehicle C by the on-vehicle camera 3 and the drive recorder 4 fixedly installed in each refuse collection vehicle, and stored in the external storage device 4a At the time of the waste collection work, the worker does not need to do the work of photographing the on-site situation. Therefore, taking a picture of the on-site situation does not burden the operator.
