PROBLEM TO BE SOLVED: To provide a video management system for a garbage truck that can eliminate waste of excessive collection of unnecessary data as much as possible. When a management server 1 receives a video delivery request, vehicle designation information, and time zone designation information from a client 2, it sends a video transmission request to the in-vehicle communication device 5 of the garbage collection vehicle C specified by the vehicle designation information. And time zone specification information is transmitted. When the in-vehicle communication device 5 receives the video transmission request and the time zone designation information, the in-vehicle communication device 5 transmits the video data captured in the time zone specified by the time zone designation information among the video data of the drive recorder 4 to the management server 1. The management server 1 stores the video data (acquired recording data) in the server-side storage device 1a, and distributes the acquired recording data to the client 2 that has transmitted the video distribution request. As a result, only necessary video data can be collected and managed. [Selection] Figure 1

Description

  The present invention relates to a video management system for managing a video obtained by photographing a field situation during collection work in a garbage truck that cyclically collects household garbage 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 dust bin that is mounted on the vehicle body and has a rear opening, and is connected to the rear opening of the dust bin, has a dust inlet, and is introduced from the inlet. A dust collecting vehicle having a dust input box provided with a dust loading device for loading dust into a dust containing box through a rear opening, and (a) a rear camera for photographing the vicinity and rear of the dust input port; (B) a front camera that captures the front of the vehicle body; (c) a rear microphone installed in the vicinity of the rear camera; (d) a monitor that displays video; and (e) a drive recorder that records video. (F) A garbage collection vehicle having a control box for inputting video signals of a front camera and a rear camera and outputting the input video signals to a monitor and a drive recorder is described.

  In this garbage truck, images taken by the front camera and the rear camera are recorded on a drive recorder and displayed on a monitor through a control box. A drive recorder can record video on an external storage device such as a USB memory, as is normally widely used (Patent Document 1 specification [0019]). The external storage device is removed from the drive recorder, taken back to the office, connected to the office computer equipment, and read out (same [0024]). The video recorded on the drive recorder can later be used for troubles in collecting dust and safety management of workers (pictures [0022] and [0024]). Further, it is also described that a side camera may be installed in order to ensure the safety of workers (same [0033]).

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

  In this waste information collection device, when the packer unit of the vehicle stops at the collection place in order to collect the waste, the collection place can be photographed by the camera. Here, when the power take-off switch is turned on by the operator for collecting the waste, the in-vehicle device causes the camera to take a picture of the state immediately before the collection of the waste collected at the collection place, and the current position is indicated in the image information. The information is added and stored in the image storage means. Thereby, it is possible to reliably photograph the discharge state of the waste for each waste collection place, and the place can be specified from the position information. This makes it possible for the residents to objectively recognize the amount of waste generated in the area by estimating and comparing the amount of discharge at each waste collection location. It becomes possible to raise the awareness for reducing the above (Patent Document 2 specification [0006]).

  Patent Document 3 discloses an image of loading or unloading waste on each waste transport vehicle acquired by an imaging means (digital camera) of a mobile terminal (mobile phone (smart phone) or the like) after arrival at each processing site. A waste disposal management system is described in which data is automatically transmitted from a terminal to a server by automatic image transmission means immediately after imaging, and the vehicle is positioned by global positioning means (GPS or the like) of a portable terminal.

  As a result, the waste processing status can be tracked and managed from a plurality of types of information including images, and falsification of image data before server transmission can be prevented.

  By the way, at the site of patrol collection by an actual garbage truck, garbage is illegally taken out at a date other than the predetermined date for garbage collection at each garbage station (household garbage collection site), or predetermined at each garbage station. There are frequent cases in which garbage other than the type of garbage (for example, “burning garbage”, “resource garbage”, “bottle / can”, etc.) is illegally sent to the garbage station. In such a case, the garbage collector and the local government cannot collect the garbage according to the established rules, and there are not a few cases where troubles occur between the residents around the garbage station and the garbage collector and the local government. In particular, in the case where garbage is taken out to the garbage station outside the specified time, there are not a few cases where it becomes a problem over the fact recognition that the garbage was taken out.

  Therefore, a garbage collector and a local government strongly demand a system capable of collecting and managing a video obtained by photographing the on-site situation at the time of collection work. In the garbage collection vehicle of Patent Document 1, the vicinity of the dust inlet and the rear are photographed with the rear camera, the video is recorded in the external storage device of the drive recorder, taken back to the office, and taken to the office computer equipment. By connecting and reading, it is possible to collect and manage the video of the on-site situation during collection work. In the waste treatment management system of Patent Document 3, an image of a field situation at the time of collection work is taken by an imaging means (digital camera) of a 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 on-site situation during the collection work.

  However, at the site of patrol collection by an actual garbage truck, an operator needs to patrol many garbage stations in a short time and collect garbage quickly. In fact, there are many cases where an operator works while running alongside a garbage truck between the garbage stations. For this reason, photographing each garbage station with a portable terminal as in the waste treatment management system of Patent Document 3 increases the work burden on the operator and leads to a delay in work time. Also, as in Patent Document 1, when the video taken by the drive recorder is taken home to the office, connected to the office computer device, read out, and managed by the office computer device, the local government is entrusted with collecting garbage. In addition, each garbage collector needs to introduce and manage computer equipment for management, which increases the cost of installing and maintaining facilities. Actually, most of the images obtained by photographing the on-site situation at the time of collection work are unnecessary data not related to troubles and the like, and collecting and managing all of them is very wasteful in terms of equipment. In addition, it is necessary to take the external storage device back to the office, connect it to the computer equipment in the office, and read it, which is time-consuming and requires management errors (forgetting to read and management information (shooting information) Mistakes such as mistakes in inputting date, place, etc.) are also likely to occur. In addition, it is assumed that necessary video data cannot be taken out until the garbage truck returns to the office, so that it is not possible to immediately respond to trouble.

  Therefore, the purpose of the present invention is not to burden the operator when photographing the on-site situation at the time of collection work, and can easily be introduced without the cost burden of installation and maintenance management of each garbage collector. Another object of the present invention is to provide a video management system for a garbage truck that can eliminate unnecessary work waste such as excessive collection of unnecessary data.
