Description

TECHNICAL FIELD The present invention relates to a trap and a management server for the trap, and more particularly to photographing of the state of capture of living things corresponding to the maintenance of the trap.

2. Description of the Related Art Conventionally, there has been known a monitoring system for periodically and repeatedly photographing a living thing such as a pest caught by a trap to monitor the captured state of the living thing. For example, Patent Literature 1 describes a pest monitoring system that monitors the types and numbers of pests. This monitoring system has a pest trapping device, a monitoring camera, a video storage device, and a terminal device. The pest trapping device traps pests. A monitoring camera regularly photographs the pests caught by the pest trapping device. The image storage device stores images periodically captured by the surveillance camera. The terminal device is network-connected to the video storage device, and displays the captured pests by video from the surveillance camera.

Further, Patent Literature 2 discloses a pest outbreak prediction system including a terminal device and a server device. The terminal device has a camera, a position information acquisition section, and a control section. The camera regularly photographs the insect trapping sheet to obtain image data. The position information acquisition unit acquires position information of the insect trapping sheet (terminal device) from a satellite positioning system such as GPS (Global Positioning System). The acquired image data and positional information are transmitted to the server device as insect repair sheet information. The server device that receives this insect trapping sheet information analyzes the image data, counts the number of pests for each insect trapping sheet, and prepares total basic information including the counted number of pests and position information. Then, the server device predicts the occurrence of insect pests based on the aggregated basic information for each insect repellent sheet.

Japanese Patent Application Laid-Open No. 2004-261155 JP 2015-154732 A

In the monitoring system described above, the shooting cycle (periodic shooting timing) of the camera is set in advance, for example, once an hour. Therefore, when maintenance of the capture device such as replacement of the capture sheet and cleaning of the inside is performed in the middle of the imaging cycle, there is a problem that the capturing state immediately before the maintenance cannot be recorded. In particular, when maintenance involves replacement of capture sheets, even if a new creature is captured between the last regular photography before maintenance and the time of maintenance, this creature will not remain as photography data, and monitoring of the capture state blank period occurs. Such a problem can be solved by performing maintenance in accordance with the regular photography of the camera, but the maintenance work is accompanied by time constraints, which imposes a heavy burden on the installation site and is not realistic.

The present invention has been made in view of such circumstances, and its object is to periodically monitor the capture state of living things and record the capture state immediately before the maintenance of the trap.

In order to solve this problem, the first invention provides a capture device having a capture section, a camera, a photographing control section, and a transmission control section, and network-connected to an external server. The trapping part catches and holds the organism. The camera captures a captured state of the organism in the capturing section. The photographing control unit instructs the camera to photograph according to a predetermined schedule, thereby periodically acquiring the first image data. At the same time, the photographing control unit instructs the camera to photograph according to the user's instruction given during the maintenance of the trap, thereby irregularly acquiring the second image data. The transmission control unit transmits the regularly acquired first image data and the irregularly acquired second image data to the external server.

In the first invention, a data storage section for storing the first image data and the second image data may be provided. Here, when the transmission control unit receives an acquisition request for image data from the external server, if only the first image data is stored in the data storage unit as a response to the acquisition request, the transmission control unit transmits the first image data. Preferably, only the data is sent to the external server. At the same time, if the data storage unit stores not only the first image data but also the second image data, the transmission control unit transmits the second image data together with the first image data to the external server. preferably.

In the first invention, the data storage unit may store a plurality of pieces of first image data acquired at different shooting timings in chronological order according to a schedule. Here, when receiving an image data acquisition request from an external server, the transmission control unit transmits the latest one in chronological order among the plurality of first image data stored in the data storage unit to the external server. Preferably send.

In the first invention, the imaging control section may reset the time count of the imaging timing defined by the schedule when the second image data is acquired.

In the first invention, when the capture device is turned off and on in accordance with a predetermined procedure as the user instruction, the photographing control unit instructs the camera to acquire the second image data. You can order to take pictures. Further, as the user instruction, the photographing control section may instruct the camera to photograph in order to acquire the second image data when a photographing switch provided in the capture device is operated. . Further, when the user instruction to take an image is given by a user terminal directly connected to the capture device or connected to the network, the image taking control unit instructs the camera to take an image to acquire the second image data. You may

A second invention provides a trap server network-connected to a trap comprising a trap for catching and holding an organism and a camera for photographing the condition of the organism being captured by the trap. The trap server has a data acquisition section, a data storage section, and a data management section. The data acquisition unit acquires first image data periodically captured by the camera according to a predetermined schedule from the capture device. At the same time, the data acquisition unit acquires from the capture device second image data captured irregularly by the camera in accordance with user instructions given during maintenance of the capture device. The data storage unit stores the first image data and the second image data acquired by the data acquisition unit. The data management section manages the second image data stored in the data storage section as final data indicating the captured state of the organism immediately before the maintenance of the trap.

Here, in the second invention, the data management unit provides the final data to be managed as the final data based on a file name that enables identification of the type of the first image data and the second image data. It is preferable to specify two image data.

In the second invention, the data acquisition unit periodically transmits an image data acquisition request to the capture device, and acquires only the first image data as a response to the acquisition request. image data may be stored in the data storage unit. At the same time, when the data acquisition section acquires not only the first image data but also the second image data, the data acquisition section may store the first image data and the second image data in the data storage section.

According to the present invention, in addition to regular photography with a camera, irregular photography triggered by a user instruction given during maintenance of a trap is allowed.

FIG. 1 is a configuration diagram of a capture monitoring network system according to this embodiment. This capture monitoring network system 1 has a plurality of traps 2 and a management server 3 (server for traps), which are network-connected to the Internet. The capture device 2 is used for capturing living things, and is installed in factories, restaurants, greenhouses, and the like, for example. Organisms to be captured are typically assumed to be flying insects that fly with wings, but are not limited to these, and include insects, animals, and birds that do not have wings, and are to be captured or exterminated. It can be widely applied to living organisms in general. The catcher 2 includes a replaceable trapping sheet 2a as an example of a trapping part that is a member for trapping living things, and the sticking surface (trapping surface) of the trapping sheet 2a traps the living organisms. The trap 2 may have a means for attracting organisms, for example, emits light of a specific wavelength or a specific smell for attracting flying insects. The catcher 2 also has a camera 2b arranged to face the adhesive surface of the capture sheet 2a, and the capture surface of the capture sheet 2a is photographed by this camera 2b.

FIG. 2 is a diagram showing an example of image data of the capture sheet 2a acquired by the camera 2b. The image data indicates the capture state of the creature on the capture sheet 2a, and is transmitted to the management server 3 in response to an acquisition request from the management server 3. FIG. In this embodiment, image data is classified into two types due to differences in shooting triggers. One is image data (hereinafter referred to as “regular image data”) that is periodically captured and acquired with a trigger of capturing timing defined by a predetermined capturing schedule, such as once an hour. ). The other is image data captured and acquired irregularly (hereinafter referred to as "irregular image data”).

The management server 3 saves the image data (regular image data/irregular image data) received from the capture device 2 as a response to its own acquisition request. In addition, the management server 3 analyzes the image data in order to specify the capture status of the capture sheet 2a, and presents the user with countermeasures to be taken at the installation site of the capture device 2 as necessary.

FIG. 3 is a block diagram of the trap 2. As shown in FIG. The capture device 2 has a photographing control section 2c, a data storage section 2d, and a transmission control section 2e in addition to the capture sheet 2a and the camera 2b described above. The photographing control unit 2c instructs the camera 2b to photograph, and stores image data acquired thereby in the data storage unit 2d. Specifically, the periodic image data is acquired periodically by repeated imaging at each imaging timing defined in a predetermined imaging schedule. In addition, irregular image data is acquired irregularly by photographing according to user instructions performed during maintenance of the capture device 2 . Irregular image data shows the final captured state just before maintenance.

Specific examples of user instructions that should be given during maintenance of the trap 2 are given below. As a first example, the photographing control unit 2c instructs the camera 2b to photograph when the trap 2 is turned off and on according to a predetermined procedure. For example, a power switch (not shown) is turned off, waited for 10 seconds, and then long-pressed for 2 seconds or more to turn it on again. As a result, it is determined that there has been a user instruction, and the camera 2b is instructed to shoot. After a certain period of time has passed, the user performs predetermined maintenance such as removing the old capturing sheet 2a from the capturing device 2 and setting a new capturing sheet 2a.

As a second example, the photographing control unit 2c instructs the camera 2b to photograph when a photographing switch (not shown) provided in the trap 2 is operated. Then, after a certain period of time has passed, the user performs predetermined maintenance. As for the structure of the catcher 2, when the catch sheet 2a is covered with an openable cover member, a switch is provided near the cover member, and when the switch detects that the cover member is opened, , the camera 2b may be instructed to shoot.

As a third example, the imaging control unit 2c instructs the camera 2b to take an image when an instruction to take an image is given by a user terminal (smartphone, etc.) directly connected to the trap 2 or connected to the network. A dedicated application for remotely controlling the capture device 2 is installed in the user terminal, and the shooting instruction for the capture device 2 is issued by this application. Then, after a certain period of time has passed, the user performs predetermined maintenance.

In order to distinguish between the regular image data and the irregular image data in the system, the imaging control unit 2c assigns a file name with both types to the image data acquired by the camera 2b. Give.

FIG. 4 is a diagram showing an example of a file name of image data. In the figure, the file name has a description that combines the capture device ID, shooting date, and type. The capture device ID is an identifier unique to the capture device 2 , and the capture date and time is the date and time when the capture sheet 2 a was captured by the camera 2 b provided in this capture device 2 . Since the shooting date and time are recorded as meta information of the image file, it is not necessarily required to be part of the file name. can be identified. As for the type, "0" indicates regular image data, and "1" indicates irregular image data. In this way, by including the type in the file name, the management server 3 can determine whether the image file received from the capture device 2 is regular image data or irregular image data by referring to the file name. can be discriminated.

It should be noted that image data type management may be performed using a separate table for managing image data types instead of file names. In this case, when transmitting image data to the management server 3, it is preferable to refer to this table and notify the management server 3 of the type of image data to be transmitted.

As shown in FIG. 5, the photographing control unit 2c resets the time count of the subsequent regular photographing timings t3 and t4 defined by the photographing schedule at the maintenance timing tm at which the maintenance of the capture device 2 is performed, The time count may be restarted with 0 seconds there. As a result, the initial photographing timing t3 is shifted to the photographing timing t3', which is the photographing cycle based on the maintenance timing tm, and the initial photographing timing t4 is the photographing cycle, which is the photographing cycle based on the shifted photographing timing t3'. Shift to timing t4'. By correcting the photographing cycle in this manner, it is possible to effectively avoid troubles that may occur when maintenance is performed at timings very close to the periodic photographing timings t1, t2, t3, and t4. Such troubles typically include a case in which an image is captured without the capture sheet 2a during maintenance work, and a case in which an operator's hand or the like is captured. By performing this correction, it is possible to secure a work period corresponding to the imaging cycle.

The data storage unit 2d has a storage area capable of storing a plurality of image data, and input/output of image data is managed by first-in first-out (FIFO). This ensures that new image data can be stored chronologically without overflowing the data storage unit 2d. The data storage unit 2d stores a plurality of regular image data acquired at different shooting timings in chronological order according to the shooting schedule. In addition, irregular image data is also stored when there is a user's instruction as described above.

The transmission control unit 2e reads the regular image data stored in the data storage unit 2d and the irregular image data (if stored) and transmits them to the external server 3. FIG. Specifically, when an acquisition request for image data is received from the external server 3, two cases are assumed as a form of response to the request. The first is a case where the capture device 2 has not been maintained for a while and only time-series regular image data is stored. In this case, as a response to the acquisition request, the latest one in chronological order among the plurality of regular image data stored in the data storage 2d is transmitted to the external server 3. FIG. Secondly, as a result of recent maintenance of the capture device 2, not only time-series regular image data but also irregular image data are stored. In this case, irregular image data is transmitted to the external server 3 together with the latest regular image data in chronological order as a response to the acquisition request.

FIG. 6 is a block diagram of the management server 3. As shown in FIG. The management server 3 has a data acquisition section 3a, a data storage section 3b, and a data management section 3c. The data acquisition unit 3a periodically transmits an image data acquisition request to the capture device 2 according to a predetermined acquisition schedule, such as once an hour, and receives image data as a response. get. The acquired image data is the regular image data/irregular image data stored in the data storage unit 2d on the capture device 2 side. If the acquired image data is only periodic image data, this periodic image data is stored in the data storage section 3b. Moreover, when the acquired image data includes not only the regular image data but also the irregular image data, both the regular image data and the irregular image data are stored in the data storage section 3b. The image data stored in the data storage unit 3b is used to analyze the capture state of the trap 2, and thereby identify the number, type, orientation (orientation), etc. of the organisms captured by the trap 2. be.

The data management unit 3c manages the irregular image data stored in the data storage unit 3b as final data indicating the capture state of the creature immediately before the maintenance of the trap 2, which is the transmission source of this data. As a result, when presenting the user with image data captured in time series by a specific capture device 2, it is possible to indicate which image capturing timing is the final data, thereby enhancing the user's convenience. can be done. The identification of irregular image data to be managed as final data is performed by referring to a file name that can identify the type of regular image data/irregular image data. Also, when the type is notified from the capture device 2 instead of the file name, irregular image data is specified based on this notification.

As described above, according to the present embodiment, in addition to regular photography by the camera 2b, irregular photography triggered by a user instruction performed during maintenance of the capture device 2 is allowed. As a result, it becomes possible to record and manage the capture state immediately before the maintenance while maintaining a periodical record of the capture state of the organism.

This point will be described in detail with reference to FIG. First, in the "comparative example" in the same figure, the photographing is performed according to the predetermined schedule. That is, the camera 2b takes pictures at four regular picture taking timings t1, t2, t3, and t4 according to a predetermined picture taking cycle. Here, for example, at timing tm located in the middle of the photographing period t2 to t3, it is assumed that the capture device 2 is maintained and the old capture sheet A is replaced with the new capture sheet B. FIG. In this case, the capture sheet A before exchange is photographed at photographing timing t2 before timing tm, and the capture sheet B after exchange is photographed at photographing timing t3 after timing tm. As a result, even if a new creature is caught on the capture sheet A before replacement during the period from t2 to tm, this creature will not be recorded as image data. That is, in the case of the comparative example, the period from t2 to tm becomes a blank period during which the capture state of the organism cannot be monitored.

On the other hand, in the "embodiment" of the figure, the camera 2b takes pictures not only at the regular picture-taking timings t1, t2, t3, and t4, but also at the timing tm. Here, when a new organism is captured during the period t2 to tm, unlike the comparative example described above, the newly captured organism is appropriately captured as the image data of capture sheet A photographed at timing tm. can be recorded. Therefore, the blank period that occurs in the comparative example can be eliminated, and it becomes possible to record the creatures captured during the period t2 to tm. Even if the maintenance does not involve exchanging the capture sheets A and B, for example, only cleaning the inside of the capture device 2, it is significant to explicitly record the image data immediately before the maintenance as the final data. is big.

Further, according to this embodiment, it is not necessary to perform maintenance of the capture device 2 in consideration of the photographing cycle of the camera 2b. The method of exchanging the trapping sheet 2a varies depending on the installation site, such as simultaneous exchange for a plurality of traps 2 or individual exchange only for traps 2 that have been confirmed to capture living things. By eliminating this, it becomes possible to respond flexibly to each installation site.

Furthermore, according to the present embodiment, a file name that can identify the type of regular image data/irregular image data is given to the image data acquired by the camera 2b. As a result, the type of image data can be identified simply by referring to the file name, so both the capture device 2 side and the management server 3 side can easily identify the data type.

In the above-described embodiment, an example in which photographed image data is acquired from the capture device 2 as a response to an acquisition request from the management server 3 has been described. The scheme is not limited to this. For example, the capture device 2 may perform imaging in real time in response to an imaging request from the management server 3, and the management server 3 may obtain image data obtained by this real-time imaging as a response to the imaging request.
