Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in a hygiene management space where stricter hygiene management is required, there are the following problems regarding the management of personal identification and specific operations. For example, there is a problem that personal identification and operation records using physical keys, touch panels, paper and pens, etc. cannot be used in a hygiene management space where non-contact is required. In addition, since there is a risk of foreign matter mixing due to dropping or breakage, there is a problem that it is difficult to bring objects that can identify individuals (ID cards, display media printed with QR codes, etc.) into the hygiene management space. In addition, wearing non-contact communication media (such as wireless tags) that can identify individuals on hygiene clothing or hats not only makes it difficult to maintain the hygiene state because the management of the clothing tends to be personal management, but also there is a problem that processing for wearing the non-contact communication media on hygiene clothing is required. In addition, wearing hats, masks, glasses, etc. has a problem that it becomes difficult to identify individuals by biometric verification because the face parts such as eyes and nose are no longer exposed. In addition, management with a checklist is difficult to record immediately after the operation, and in the case of self-reporting outside the hygiene management space, there are problems such as forgetting to write, recording errors, and fraud.

[0006] The present invention has been made to solve the above-described problems, and an object thereof is to provide a configuration that can confirm the identity of a person non-contact in a hygiene management space without requiring the bringing in of an object for personal identification.

Note that the reference signs in the parentheses above indicate the correspondence with the specific means described in the embodiments described later.

Advantage of the Invention

[0009] In the present invention, when authentication is successful by an authentication unit that performs personal authentication using personal identification information received from an authentication device, the server generates predetermined identification operation information associated with the personal identification information and transmits it to the authentication device and the inspection device, respectively. When the authentication device receives and acquires the predetermined identification operation information from the server by transmitting the acquired personal identification information to the server, the authentication device displays the predetermined identification operation information. After a positive determination by a first determination unit that the personal identification operation of the worker imaged by the imaging unit is an operation specified from the predetermined identification operation information received from the server, the inspection device determines by a second determination unit whether or not a predetermined action by the worker imaged as an inspection target by the imaging unit satisfies the predetermined action conditions, and transmits information including the determination result by the second determination unit to the server as an inspection result.

[0010] Thereby, the worker can make the inspection device recognize that he / she is the inspection target person who has succeeded in authentication by performing, as a personal identification operation, an operation specified from the predetermined identification operation information displayed on the authentication device at the time of successful authentication outside the hygiene management space, on the imaging unit of the inspection device inside the hygiene management space. Therefore, it is possible to realize a system capable of non-contact personal confirmation inside the hygiene management space without the need to bring in an object for personal identification.

[0011] In the present invention, when the authentication by the authentication unit of the server using the personal identification information received from the authentication device is successful, the server generates predetermined identification operation information associated with the personal identification information and transmits it to the authentication device and the inspection device respectively. After that, the server transmits to the inspection device the inspection result of inspecting whether a predetermined operation specified from the inspection information received from the inspection device satisfies the predetermined operation conditions. When the authentication device receives and acquires the predetermined identification operation information from the server by transmitting the acquired personal identification information to the server, the authentication device displays the predetermined identification operation information. After the determination unit of the inspection device makes an affirmative determination that the personal identification operation of the worker imaged by the imaging unit is an operation specified from the predetermined identification operation information received from the server, the inspection device transmits the inspection information generated so as to be able to evaluate the predetermined operation by the worker imaged as the inspection target by the imaging unit to the server, and thus receives and acquires the inspection result from the server.

[0012] Even in this way, when the authentication is successful outside the hygiene management space, the worker can perform, as a personal identification operation, the operation specified from the predetermined identification operation information displayed on the authentication device inside the hygiene management space for the imaging unit of the inspection device, so that the server and the inspection device can recognize that the worker is the inspected person who has successfully authenticated. Therefore, it is possible to realize a system capable of non-contact personal confirmation inside the hygiene management space without the need to bring in an object for personal identification.

[0013] The predetermined operation imaged as the inspection target by the inspection device may be a handwashing operation, and the personal identification operation may be an operation using hand movements.

[0014] As a result, since the determination target by the first determination unit and the determination target by the second determination unit are the same hand movement, the imaging unit for the first determination unit and the imaging unit for the second determination unit can be easily shared, and simplification and space saving of the inspection device can be achieved.

[0015] At the entrance to the hygiene management space, a door that automatically opens and closes upon receiving an open instruction when the authentication is successful may be provided.

[0016] As a result, since an operator who fails authentication cannot enter the hygiene management space, the authentication result by the authentication unit can be diverted to the entry / exit management of the hygiene management space.

[0017] The inspection device generates feature data regarding a predetermined operation by the operator based on the imaging result used for the determination by the second determination unit, and transmits an inspection result including this feature data to the server. The server may perform identity verification based on the feature data received from the inspection device and a plurality of feature data stored in the storage unit for the same operator.

[0018] As a result, even if a positive determination is made by the first determination unit and the second determination unit regarding the personal identification operation and a predetermined operation by another person who is different from the operator who has successfully authenticated and who visually recognizes the predetermined identification operation information displayed on the authentication device, the server can recognize that the other person is the person to be inspected because the plurality of feature data stored in the storage unit for the same operator as the feature data received from the inspection device is different.

[0019] The server generates feature data regarding a predetermined operation by the operator based on the inspection information received from the inspection device, stores it in the storage unit, and may perform identity verification based on the generated feature data and a plurality of feature data stored in the storage unit for the same operator.

[0020] As a result, even if a positive determination is made by the determination unit regarding the personal identification operation by another person who is different from the operator who has successfully authenticated and who visually recognizes the predetermined identification operation information displayed on the authentication device, the server can recognize that the other person is the person to be inspected because the plurality of feature data stored in the storage unit for the same operator as the feature data generated based on the inspection information received from the inspection device is different.

[0021] The above-mentioned predetermined operation is divided into a plurality of operation stages, and the inspection device may be installed for each operation stage.

[0022] Thus, even when it is necessary to perform predetermined operations to be inspected at different locations due to strict hygiene management, by installing inspection devices at each location, inspections can be performed on the operation stages to be inspected among the predetermined operations at each inspection device according to the predetermined identification operation information received from the server.

[0024] [First embodiment] A first embodiment of a hygiene management system according to the present invention will be described below with reference to the drawings. The hygiene management system 1 of this embodiment is a system for managing specified actions performed by workers whose identities have been verified within a hygiene management space 2, and as shown in Figure 1, is configured to include an authentication device 10, multiple inspection devices 20, and a server 30 that can communicate with each of these devices.

[0025] In this embodiment, the hygiene management space 2 is configured by a hand-washing room installed before the food production line, and multiple hand-washing stations 3 are installed in this hygiene management space 2. In this embodiment, the predetermined actions to be managed are hand-washing actions at each hand-washing station 3 (specifically, for example, wetting the hands with running water, applying soap, etc., and then washing the palms, backs of the hands, fingertips, between the fingers, wrists, etc.). For convenience, Figure 1 and other figures show only a first hand-washing station 3a and a second hand-washing station 3b out of the multiple hand-washing stations 3.

[0026] As shown in Figures 1 and 2, an automatically opening and closing door 4 is provided at the entrance and exit of the hand washing room. The door 4 is controlled to open and close by a door opening and closing control device 5 shown in Figure 3, and is configured to be controlled to the open state when the door opening and closing control device 5 receives an open instruction from an authentication device 10 when authentication is successful.

[0027] The authentication device 10 is a face authentication device installed on the wall surface near the door 4 outside the sanitary management space 2. As shown in FIG. 3, it includes a control unit 11, a storage unit 12, an imaging unit 13, a display unit 14, an operation unit 15, a communication unit 16, etc.

[0028] The control unit 11 is mainly composed of a microcomputer and performs overall control and various calculations of the authentication device 10, and functions to execute identification operation information display processing and the like described later. The storage unit 12 is composed of a ROM, a RAM, an HDD, a non-volatile memory, etc., and an application program for executing identification operation information display processing, a predetermined database, etc. are pre-stored so as to be available for use by the control unit 11.

[0029] The imaging unit 13 is a camera equipped with a light receiving sensor (for example, a C-MOS area sensor, a CCD area sensor, etc.), and is arranged so that the face of an operator or the like who can visually recognize the display screen 14a of the display unit 14 is within the imaging range through the imaging window 13a. This imaging unit 13 is controlled by the control unit 11 and is configured to output the captured image data to the control unit 11. The display unit 14 is configured such that the display content of the display screen 14a composed of a liquid crystal display panel or the like is controlled by the control unit 11. The operation unit 15 is configured to output an operation signal corresponding to an input operation on a plurality of keys 15a to the control unit 11, and the control unit 11 performs processing corresponding to the input operation in response to this operation signal. The communication unit 16 is configured as a communication interface for performing data communication with external devices such as the server 30 and the door opening / closing control device 5, and is configured to perform communication processing in cooperation with the control unit 11.

[0030] In the authentication device 10 configured as described above, in the identification operation information display process performed by the control unit 11, when the imaging unit 13 captures the face of an operator or the like, face feature point data (data regarding the size, shape, contour of each face organ such as eyes, eyebrows, nose, ears, mouth, etc., and the arrangement position between face organs) extracted by a known face feature point extraction process from the face image is acquired as personal identification information and transmitted to the server 30 via the communication unit 16. In response to this transmission, when a predetermined identification operation information is received and acquired as successful authentication from the server 30 as described later, the predetermined identification operation information is displayed on the display screen 14a of the display unit 14 (see Fig. 2(B)), and an open instruction is transmitted to the door opening / closing control device 5. The above-mentioned predetermined identification operation information will be described later. Note that the control unit 11 and the imaging unit 13 that perform the above-mentioned face feature point extraction process correspond to an example of a "personal identification information acquisition unit" for acquiring face feature point data (personal identification information), and the control unit 11 and the communication unit 16 that perform the process of receiving and acquiring predetermined identification operation information from the server 30 by transmitting the face feature point data (personal identification information) to the server 30 may correspond to an example of an "identification operation information acquisition unit".

[0031] The inspection device 20 is a handwashing inspection device installed for each handwashing area 3. As shown in Fig. 3, it includes a control unit 21, a storage unit 22, an imaging unit 23, a display unit 24, an operation unit 25, a communication unit 26, etc. In Fig. 1 and the like, for convenience, the inspection device installed in the first handwashing area 3a is labeled with reference numeral 20a, and the inspection device installed in the second handwashing area 3b is labeled with reference numeral 20b.

[0032] The control unit 21 is mainly composed of a microcomputer and performs overall control and various operations of the inspection device 20, and functions to execute handwashing inspection processes and the like described later. The storage unit 22 is composed of a ROM, a RAM, an HDD, a non-volatile memory, etc., and an application program for executing handwashing inspection processes, a predetermined database, etc. are pre-stored in a manner that can be used by the control unit 21.

[0033] The imaging unit 23 is a camera equipped with a light-receiving sensor (e.g., a C-MOS area sensor, a CCD area sensor, etc.), and is arranged so that the hands of the operator performing the handwashing operation are within the imaging range. This imaging unit 23 is configured to be controlled by the control unit 21 and output the captured image data to the control unit 21. The display unit 24 is composed of a known liquid crystal display panel or the like, and is configured such that its display content is controlled by the control unit 21. The operation unit 25 is configured to output an operation signal corresponding to an input operation to the control unit 21, and the control unit 21 performs processing corresponding to the input operation upon receiving this operation signal. The communication unit 26 is configured as a communication interface for performing data communication with external devices such as the server 30 and other inspection devices 20, and is configured to perform communication processing in cooperation with the control unit 21.

[0034] In the inspection device 20 configured as described above, when predetermined identification operation information is received from the server 30 as will be described later, the control unit 21 starts the handwashing inspection process. In this handwashing inspection process, the inspection start operation and the personal identification operation by the operator are imaged, and then it is determined whether the handwashing operation by the operator satisfies the predetermined operation conditions by using the captured image of the handwashing operation. Then, the determination result and the like are displayed on the screen by the display unit 24 and transmitted to the server 30 as the inspection result.

[0035] In this embodiment, for the handwashing operation to be inspected, the operation stages to be evaluated, such as the operation of wetting the hands with running water, the operation of applying soap, etc., the operation of washing the palm, the back of the hand, the fingertips, between the fingers, the wrist, etc., are classified. And when the result of quantifying the comparison result between the reference operation (the recommended handwashing operation) preset for each operation stage and the imaged operation to be evaluated is equal to or greater than the specified value, it is determined that the handwashing operation satisfies the predetermined operation conditions. Note that the above-described inspection start operation and personal identification operation will be described later.

[0036] Server 30 is a terminal for managing personal authentication using personal identification information received from the authentication device 10, inspection results from each inspection device 20, etc. As shown in FIG. 3, it includes a control unit 31, a storage unit 32, a display unit 33, an operation unit 34, a communication unit 35, and the like.

[0037] The control unit 31 is mainly composed of a microcomputer and performs overall control of the server 30 and various calculations, and functions to execute personal authentication processing, identification operation information transmission processing, etc. described later. The storage unit 32 is composed of a ROM, a RAM, an HDD, a non-volatile memory, etc., and application programs and a predetermined database for executing personal authentication processing and identification operation information transmission processing are pre-stored so as to be available for use by the control unit 31.

[0038] The display unit 33 is a so-called monitor, and its display content is configured to be controlled by the control unit 31. The operation unit 34 is configured to output an operation signal corresponding to an input operation to the control unit 31, and the control unit 31 performs processing corresponding to the input operation upon receiving this operation signal. The communication unit 35 is configured as a communication interface for performing data communication with external devices such as the authentication device 10, the inspection device 20, and the door opening / closing control device 5, and is configured to perform communication processing in cooperation with the control unit 31.

[0039] In the server 30 configured in this way, when face feature point data, etc. is received as personal identification information from the authentication device 10 via the communication unit 35, the control unit 31 starts personal authentication processing. In this personal authentication processing, a known collation process is performed to collate the face feature point data registered in the database of the storage unit 32 together with the worker ID, etc. in advance with the face feature point data received as described above. Note that the control unit 31 that performs the above personal authentication processing using the personal identification information received from the authentication device 10 may correspond to an example of an "authentication unit".

[0040] When it is determined from the collation result that authentication is successful and the operator ID is specified, the control unit 31 generates predetermined identification operation information by including the operator ID, the authentication result, the washroom information designating the washroom 3, and information specifying the randomly set inspection start operation and personal identification operation. The predetermined identification operation information set in this way is transmitted to the authentication device 10 and the inspection device 20 via the communication unit 35, and is recorded (registered) in the database of the storage unit 32. Then, the inspection result received from the inspection device 20 that has transmitted the predetermined identification operation information, as will be described later, is recorded in the database of the storage unit 32 in association with the operator ID and the like. Note that the control unit 31 that performs the above-described identification operation information generation process for generating the predetermined identification operation information corresponds to an example of an "identification operation information generation unit", and the communication unit 35 that performs the process of transmitting the predetermined identification operation information to the authentication device 10 and the inspection device 20 respectively may correspond to an example of an "identification operation information transmission unit".

[0041] In the present embodiment, as the inspection start operation and the personal identification operation, an operation by the operator's finger, more specifically, an operation of changing the number of extended fingers is adopted. The inspection start operation is an operation for notifying the inspection device 20 of the intention to start handwashing after visually recognizing the predetermined identification operation information. In the present embodiment, one type of number of fingers is prepared. The personal identification operation is an operation for indicating that the operator who has successfully authenticated performs the handwashing operation. In the present embodiment, four types of numbers of fingers and their order are prepared.

[0042] For example, in the example of FIG. 2(B), since the operator with the operator ID of "123456" has been successfully authenticated, the first washroom 3a is designated, and as the inspection start operation, an operation of setting the number of extended fingers to "0" is set, and as the personal identification operation, an operation of setting the number of extended fingers in the order of "2", "1", "3", "4" is set. The predetermined identification operation information displayed on the display screen 14a of the authentication device 10 is illustrated.

[0043] Hereinafter, in this embodiment, the personal authentication etc. before entering the hygiene management space 2 and the identity confirmation and handwashing operation inspection within the hygiene management space 2 will be described in detail with reference to the drawings.

[0044] First, regarding the identification operation information display process performed by the control unit 11 of the authentication device 10 and the personal authentication process performed by the control unit 31 of the server 30 when an operator enters the hygiene management space 2, it will be described in detail with reference to the flowchart shown in FIG. 4 and the sequence diagram shown in FIG. 5 etc.

[0045] The operator can visually recognize the predetermined identification operation information received by the authentication device 10 from the server 30 and displayed on the display screen 14a by facing the face towards the imaging window 13a of the authentication device 10 (F11, F12). In this state, since the door 4 is controlled to be in the open state by the door opening / closing control device 5, the operator can enter the hygiene management space 2 while visually recognizing the predetermined identification operation information on the display screen 14a.

[0046] In the authentication device 10, when the operator enters the imaging range of the imaging unit 13 of the authentication device 10, the control unit 11 starts the identification operation information display process, captures the face of the operator (S101: F21), and performs a process for extracting face feature points from the captured image (S102). When the extraction of the face feature points is successful (Yes in S103), the face feature point data etc. is transmitted to the server 30 as personal identification information via the communication unit 16 (S104: F22).

[0047] When predetermined identification operation information is received from the server 30 in response to the above transmission (Yes in S105), the received predetermined identification operation information is displayed on the display screen 14a as a display accompanying the authentication result (S106: F23). Then, an open instruction is transmitted to the door opening / closing control device 5 via the communication unit 16 (S107), and this identification operation information display process ends. Incidentally, when authentication failure information is received from the server 30 as will be described later (No in S105), information indicating that authentication has failed is displayed on the display screen 14a and notified (S108), and this identification operation information display process ends.

[0048] At the server 30, when personal identification information (such as face feature point data) is received from the authentication device 10 via the communication unit 35, the control unit 31 starts the personal authentication process (F31). Then, the control unit 31 generates predetermined identification operation information as described above through the identification operation information generation process performed at the time of successful authentication (F32). The predetermined identification operation information thus generated is transmitted to both the authentication device 10 and the inspection device 20 of the designated handwashing area 3 via the communication unit 35 (F33), and is recorded (registered) in the database of the storage unit 32 (F34). When authentication fails, no predetermined identification operation information is generated, and authentication failure information indicating that authentication has failed is transmitted to the authentication device 10 via the communication unit 35.

[0049] Next, when the operation of the operator who has entered the hygiene management space 2 is inspected for handwashing, the handwashing inspection process and the like performed by the control unit 21 of the inspection device 20 will be described in detail with reference to the flowchart shown in FIG. 6 and the sequence diagram shown in FIG. 7.

[0050] The operator goes to the handwashing area 3 designated by the above-mentioned predetermined identification operation information (F13), and after performing an inspection start operation specified from the predetermined identification operation information visually recognized as described above on the inspection device 20 installed in the handwashing area 3 (F14), by performing a personal identification operation (F15), the inspection device 20 becomes capable of inspecting the operator's handwashing operation. The operator then performs a handwashing operation (F16), and since the inspection result of the handwashing operation is displayed on the display unit 24 of the inspection device 20, the operator can recognize whether his / her handwashing operation is being performed correctly.

[0051] In the inspection device 20, when predetermined identification operation information is received from the server 30 and the control unit 21 starts the handwashing inspection process, the imaging unit 23 becomes capable of imaging (S201), and the captured image of the imaging unit 23 and the operator ID etc. included in the predetermined identification operation information received as described above are displayed on the display unit 24 (S202: F41).

[0052] After the elapse time T from the reception of the predetermined identification operation information by the timer is started (S203), in the determination process of step S204, it is determined whether or not the elapse time T is equal to or longer than a hand-washing start operation enable time Tth set in advance. In a state where the elapse time T is less than the hand-washing start operation enable time Tth (No in S204), in the inspection start operation detection process shown in step S205, a process for detecting the inspection start operation specified by the predetermined identification operation information from the captured image by the imaging unit 23 is performed.

[0053] Since the worker visually recognizing the predetermined identification operation information is correctly performing the inspection start operation, when the inspection start operation specified by the predetermined identification operation information is detected from the captured image (Yes in S206: F42), the detection result notification process shown in step S207 is performed. In this process, information indicating the success of detecting the inspection start operation and information prompting the start of the personal identification operation are notified using the display by the display unit 24 (F43). When the inspection start operation is not detected from the captured image (No in S206), the process from the above step S204 is repeated.

[0054] When information prompting the start of the personal identification operation and the like is notified as described above, in the personal identification operation detection process shown in step S208, a process for detecting the personal identification operation specified by the predetermined identification operation information from the captured image by the imaging unit 23 is performed (F44). Subsequently, in the determination process of step S209, it is determined whether or not the personal identification operation of the worker imaged by the imaging unit 23 is an operation specified from the predetermined identification operation information received from the server 30. The control unit 21 that performs the determination process of step S209 may correspond to an example of a "first determination unit".

[0055] In the above-described personal identification operation detection process, when a personal identification operation specified by predetermined identification operation information is detected from the captured image (Yes in S209), the detection result notification process shown in step S210 is performed. In this process, information indicating the successful detection of the personal identification operation and information prompting the start of the handwashing operation are notified using the display by the display unit 24, etc. (F45). When the personal identification operation is not detected from the captured image (No in S209), in the retry information display process shown in step S211, after information indicating that the personal identification operation is incorrect, etc. is displayed on the display unit 24 as retry information, the processes after the above step S204 are performed.

[0056] When information prompting the start of the handwashing operation, etc. is notified as described above, the handwashing evaluation process shown in step S212 is performed, and a process for evaluating the operator's handwashing operation from the continuous captured images (moving images) by the imaging unit 23 is performed as described above (F46).

[0057] Subsequently, in the determination process of step S213, it is determined whether the operator's handwashing operation satisfies the predetermined operation conditions. Here, since the comparison result between the captured evaluation target operation and the above reference operation is equal to or greater than the specified value, when it is determined that the handwashing operation satisfies the above predetermined operation conditions (Yes in S213), in the inspection result notification process of step S214, the inspection result (determination result), etc. obtained by aggregating each evaluation result is notified using the display by the display unit 24, etc. (F47). Then, the inspection result, etc. is transmitted to the server 30 via the communication unit 26 (S215: F48), and this handwashing inspection process ends. The control unit 21 that performs the determination process of the above step S213 may correspond to an example of the "second determination unit". Also, the display unit 24 that displays the inspection result, etc. corresponds to an example of the "notification unit" that notifies the determination result by the "second determination unit", and the communication unit 26 that performs the process of transmitting the inspection result, etc. to the server 30 may correspond to an example of the "inspection result transmission unit".

[0058] On the other hand, if it is determined that the handwashing operation does not satisfy the above-mentioned predetermined operating conditions because the comparison result in at least a part of the imaging target operation to be evaluated is less than the specified value (No in S213), the retry information display process shown in step S216 is performed. In this process, after information indicating that the handwashing operation is not being performed correctly is displayed on the display unit 24 as retry information, the process from the above step S212 is performed. Note that in the retry information display process of step S216, the operator may be notified by displaying the correct handwashing operation, the evaluation target operation that is less than the specified value, etc. on the display unit 24.

[0059] Also, if the elapsed time T from the reception of the above-mentioned predetermined identification operation information becomes equal to or more than the handwashing start operation enable time Tth because the inspection start operation and the personal identification operation are not performed correctly (Yes in S204), the error display process shown in step S217 is performed. In this process, a message indicating that the inspection start operation or the personal identification operation is not being performed correctly is displayed on the display unit 24, and this handwashing inspection process ends.

[0060] In the server 30, when the inspection result etc. is received from the inspection device 20 that has transmitted the predetermined identification operation information via the communication unit 35 as described above, the inspection result etc. is recorded in the database of the storage unit 32 so as to be associated with the operator ID etc. (F35).

[0061] As described above, in the hygiene management system 1 according to the present embodiment, when the server 30 succeeds in personal authentication performed using the personal identification information received from the authentication device 10, the server 30 generates predetermined identification operation information associated with the personal identification information and transmits it to the authentication device 10 and the inspection device 20, respectively. When the authentication device 10 installed outside the hygiene management space 2 receives and acquires predetermined identification operation information from the server 30 by transmitting the acquired personal identification information to the server 30, the authentication device 10 displays this predetermined identification operation information on the display screen 14a. After positively determining that the personal identification operation of the worker imaged by the imaging unit 23 of the inspection device 20 installed in the hygiene management space 2 is an operation specified from the predetermined identification operation information received from the server 30, the inspection device 20 determines whether or not the handwashing operation by the worker imaged as the inspection target by the imaging unit 23 satisfies the predetermined operation conditions, and transmits information including the determination result to the server 30 as an inspection result.

[0062] Thereby, the worker can make the inspection device 20 recognize that the worker is the inspection target person who has succeeded in authentication by performing, as a personal identification operation, the operation specified from the predetermined identification operation information displayed on the authentication device 10 at the time of successful authentication outside the hygiene management space 2, on the imaging unit 23 of the inspection device 20 inside the hygiene management space 2. Therefore, it is possible to realize a system that can confirm the identity of a person without contact inside the hygiene management space 2 without the need to bring in an object for personal identification.

[0063] In particular, in the present embodiment, the predetermined operation imaged as the inspection target of the inspection device 20 is a handwashing operation, and the personal identification operation is set to an operation using hand movements.

[0064] As a result, since the determination target in the determination process (first determination unit) of step S209 and the determination target in the determination process (second determination unit) of step S213 are the same hand movement, the imaging unit for the determination process of step S209 and the imaging unit for the determination process of step S213 can be easily shared as the imaging unit 23, and simplification and space saving of the inspection apparatus 20 can be achieved. Similarly, since the inspection start operation is also set to an operation using hand movement, the determination target in the determination process of step S206 and the determination target in the determination process of step S213 are the same hand movement, so the imaging unit for the determination process of step S206 can also be shared as described above.

[0065] In this embodiment, a door 4 that automatically opens and closes upon receiving an open instruction when authentication is successful is provided at the entrance to the hygiene management space 2.

[0066] As a result, an operator who fails authentication cannot enter the hygiene management space 2, so the authentication result at the server 30 can be diverted to the entry / exit management of the hygiene management space 2.

[0067] [Second Embodiment] Next, the hygiene management system according to the second embodiment will be described with reference to the drawings. In the second embodiment, the main difference from the first embodiment is that the inspection information generated to inspect the handwashing operation by the operator imaged by the inspection apparatus 20 as the inspection target is transmitted to the server 30, and the server 30 inspects whether the handwashing operation of the operator satisfies the predetermined operation conditions. Therefore, the same reference numerals are given to substantially the same components as those in the first embodiment, and the description thereof is omitted.

[0068] In the handwashing inspection process performed by the control unit 21 of the inspection device 20 in the present embodiment, as shown in the flowchart of FIG. 8 and the sequence diagram of FIG. 9, after information prompting the start of the handwashing operation is notified (S210), the inspection information generation process shown in step S220 is performed. In this process, inspection information is generated so that the handwashing operation by the operator can be evaluated in order to inspect the handwashing operation by the operator (F50). In the present embodiment, a moving image continuously captured by the imaging unit 23 of the operator's handwashing operation is adopted as the above inspection information, and the moving image is transmitted to the server 30 as inspection information at the timing when the handwashing operation is completed (S221: F51).

[0069] When the server 30 receives inspection information (moving image) from the inspection device 20, the control unit 31 performs a process (handwashing evaluation process) to determine whether the handwashing operation specified from the above inspection information satisfies the predetermined operation conditions. The same process as the determination process in step S213 in the first embodiment is performed (F36). When it is determined that the handwashing operation satisfies the predetermined operation conditions, a pass determination result is transmitted to the inspection device 20 via the communication unit 35 as an inspection result. When it is determined that the handwashing operation does not satisfy the predetermined operation conditions, a fail determination result is transmitted to the inspection device 20 via the communication unit 35 as an inspection result (F37). Then, the result of this inspection process is recorded in the database of the storage unit 32 so as to be associated with the relevant operator ID and the like (F35). Note that the control unit 31 that performs the above inspection process may correspond to an example of an "inspection unit".

[0070] On the other hand, in the inspection device 20, when a pass judgment result is received and acquired as an inspection result from the server 30 that has transmitted the inspection information via the communication unit 26 (Yes in S222), the pass judgment result and the like are notified using the display on the display unit 24 (S223: F52), and this handwashing inspection process ends. Also, when a fail judgment result is received and acquired as an inspection result from the server 30 that has transmitted the inspection information (No in S222), the retry information display process shown in step S216 above is performed. Note that, by transmitting the inspection information to the server 30 as described above, the control unit 21 and the communication unit 26 that perform the process of receiving and acquiring the inspection result from the server 30 can correspond to an example of an "inspection result acquisition unit".

[0071] As described above, in the hygiene management system 1 according to the present embodiment, the server 30 generates predetermined identification operation information associated with the personal identification information and transmits it to the authentication device 10 and the inspection device 20 respectively. After that, the server 30 transmits an inspection result to the inspection device 20 regarding whether the handwashing operation specified from the inspection information received from the inspection device 20 satisfies the predetermined operation conditions. The inspection device 20 installed in the hygiene management space 2 transmits the inspection information generated so as to be able to evaluate the handwashing operation by the operator imaged as the inspection target by the imaging unit 23 to the server 30 after an affirmative determination that the personal identification operation of the operator imaged by the imaging unit 23 is an operation specified from the predetermined identification operation information received from the server 30, and thus receives and acquires the inspection result from the server 30.

[0072] Even in this way, the operator can make the server 30 and the inspection device 20 recognize that they are the inspected person who has succeeded in authentication by performing, as a personal identification operation, the operation specified from the predetermined identification operation information displayed on the authentication device 10 when authentication is successful outside the hygiene management space 2, with respect to the imaging unit 23 of the inspection device 20 inside the hygiene management space 2. Therefore, it is possible to realize a system that can confirm the identity of a person non - contactlessly inside the hygiene management space 2 without the need to bring in an object for personal identification.

[0073] [Third Embodiment] Next, the hygiene management system according to the third embodiment will be described with reference to the drawings. In the third embodiment, the main difference from the first embodiment is that characteristic data generated regarding the handwashing operation by the operator is accumulated and used for personal identification based on the imaging result used in the determination process as to whether or not the predetermined operating conditions are satisfied. Therefore, components substantially the same as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[0074] For example, if a person other than the authenticated operator visually recognizes the predetermined identification operation information displayed on the display screen 14a of the authentication device 10, correct operations may be detected for the personal identification operation and the handwashing operation by that other person, and as a result, the inspection result of the handwashing operation by that other person may be registered in the server 30.

[0075] Therefore, in this embodiment, the inspection device 20 generates characteristic data (habits and patterns of actions) regarding the handwashing operation by the operator based on the imaging result used in the determination process of step S213, and transmits an inspection result including the characteristic data to the server 30. Then, the server 30 performs personal identification based on the characteristic data received from the inspection device 20 and the plurality of characteristic data stored in the storage unit 32 for the same operator (operator ID).

[0076] Specifically, in the handwashing inspection process performed by the control unit 21 of the inspection device 20 in this embodiment, as shown in the flowchart of FIG. 10 and the sequence diagram of FIG. 11, when it is determined that the handwashing operation satisfies the above-described predetermined operating conditions (Yes in S213), the characteristic data generation process shown in step S230 is performed. In this process, characteristic actions are digitized for each of the above-described operation stages (the action of wetting the hands with running water, the action of applying soap, etc., the action of washing the palms, the backs of the hands, the fingertips, between the fingers, the wrists, etc.), and characteristic data is generated (F53). Note that the control unit 21 that performs the above-described characteristic data generation process may correspond to an example of a "characteristic data generation unit".

[0077] After the inspection results including the feature data generated in this way are transmitted to the server 30 via the communication unit 26 (S215: F48), the inspection result notification process in step S214 is performed. In the present embodiment, when the personal verification result received from the server 30 in response to the transmission of the inspection results is valid, the inspection results are notified using the display on the display unit 24 in the same manner as in the first embodiment. When the received personal verification result is inappropriate, predetermined warning information indicating that the personal verification result is inappropriate is notified using the display on the display unit 24 (F47).

[0078] At the server 30, when the inspection results including the feature data are received, the control unit 31 performs a personal verification process based on a plurality of feature data stored in the storage unit 32 for the same operator (operator ID) as the feature data received from the inspection device 20. In this process, the similarity obtained by comparing the received feature data with the stored feature data is calculated as a score.

[0079] When the score calculated as described above is equal to or greater than a predetermined threshold, a personal verification result indicating validity is transmitted to the inspection device 20. When the calculated score is less than the predetermined threshold, a personal verification result indicating inappropriateness is transmitted to the inspection device 20 (F38). The feature data for which a personal verification result indicating validity is obtained is recorded (stored) in the database of the storage unit 32 in association with the operator ID and the like together with the inspection results and the like (F35).

[0080] As described above, in the hygiene management system 1 according to the present embodiment, the inspection device 20 generates feature data related to the handwashing operation by the operator based on the imaging result used in the determination process of step S213, and transmits the inspection result including this feature data to the server 30. The server 30 performs personal verification based on a plurality of feature data stored in the storage unit 32 for the same operator as the feature data received from the inspection device 20.

[0081] As a result, even if a positive determination is made in the determination processes of steps S209 and S213 regarding the personal identification operation and the predetermined operation by another person who visually recognizes the predetermined identification operation information displayed on the authentication device 10, which is different from the authenticated operator, the server 30 can recognize that the other person is the inspection target because the feature data received from the inspection device 20 is different from the plurality of feature data stored in the storage unit 32 for the same operator.

[0082] [Fourth Embodiment] Next, the hygiene management system according to the present fourth embodiment will be described with reference to the drawings. In the present fourth embodiment, based on the imaging result used for the determination process of whether or not the default operation conditions are satisfied, the feature data generated regarding the handwashing operation by the operator is accumulated and used for personal identification, which is mainly different from the second embodiment described above. Therefore, the same reference numerals are given to the substantially same components as those in the second embodiment, and the description thereof is omitted.

[0083] In the present embodiment, similar to the second embodiment, on the premise that the server 30 that has received the inspection information from the inspection device 20 determines whether the handwashing operation of the operator satisfies the default operation conditions, similar to the third embodiment, the feature data generated based on the imaging result used for the determination process in the server 30 is accumulated and used for personal identification.

[0084] Specifically, in the handwashing inspection process performed by the control unit 21 of the inspection device 20 in the present embodiment, as shown in the flowchart of FIG. 8 and the sequence diagram of FIG. 12, by transmitting the inspection information generated as described above to the server 30 (S221: F51), a pass determination result or a fail determination result is received as the inspection result via the communication unit 26 (F52).

[0085] At the server 30, after generating feature data from the inspection information received from the inspection device 20 in the same manner as the feature data generation process in step S230, the above-described identity verification process is performed based on the generated feature data and the plurality of feature data stored in the storage unit 32 for the same operator (operator ID) (F39).

[0086] When an identity verification result indicating validity is obtained by the above-described identity verification process, a process similar to the determination process in step S213 in the first embodiment is performed as to whether the handwashing operation specified from the inspection information satisfies the predetermined operation conditions (F36). And when it is determined that the handwashing operation satisfies the predetermined operation conditions, a pass determination result is transmitted to the inspection device 20 as an inspection result together with the identity verification result indicating validity, and when it is determined that the handwashing operation specified from the inspection information does not satisfy the predetermined operation conditions, a fail determination result is transmitted to the inspection device 20 as an inspection result together with the identity verification result indicating validity (F37). The feature data for which an identity verification result indicating validity is obtained is recorded (stored) in the database of the storage unit 32 in association with the operator ID and the like together with the inspection result and the like (F35).

[0087] On the other hand, when an identity verification result indicating invalidity is obtained by the above-described identity verification process, the identity verification result indicating invalidity is transmitted to the inspection device 20 as an inspection result without evaluating the handwashing operation (F37).

[0088] As described above, in the hygiene management system 1 according to the present embodiment, the server 30 generates feature data regarding the handwashing operation by the operator based on the inspection information received from the inspection device 20 and stores it in the storage unit 32, and performs identity verification based on the generated feature data and the plurality of feature data stored in the storage unit 32 for the same operator.

[0089] Even in this case, if someone other than the authenticated operator visually recognizes the predetermined identification operation information displayed on the authentication device 10, even if a positive determination is made in the determination process (determination unit) of step S209 regarding the personal identification operation by that other person, the server 30 can determine that the person being inspected is someone other than the operator because the feature data generated based on the inspection information received from the inspection device 20 is different from the multiple pieces of feature data stored in the storage unit 32 for the same operator.

[0090] [Fifth Embodiment] Next, the hygiene management system according to this fifth embodiment will be described with reference to the drawings. In this fifth embodiment, the main difference from the first embodiment is that a plurality of inspection devices 20 are used to inspect one handwashing operation. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0091] Due to reasons such as strict hygiene management, the handwashing operations to be inspected may be performed at different locations for each stage. For example, since handwashing with two types of soap is required, the inspection location for the handwashing operation using the first soap and the inspection location for the handwashing operation using the second soap may be separated.

[0092] Assuming such a case, in this embodiment, the handwashing operations to be inspected are divided into multiple operation stages, with the handwashing operation using the first soap as the first operation stage and the handwashing operation using the second soap as the second operation stage, and inspection devices 20 are installed at each handwashing location.

[0093] Assuming that the handwashing operation using the first soap is performed at the first handwashing area 3a, the first operation stage is inspected by the inspection device 20a installed at the first handwashing area 3a. Assuming that the handwashing operation using the second soap is performed at the second handwashing area 3b, the second operation stage is inspected by the inspection device 20b installed at the second handwashing area 3b.

[0094] In this case, after successful authentication, the server 30 transmits to the authentication device 10 predetermined identification operation information generated so that the first hand-washing area 3a is designated in the hand-washing area information (F33). Similarly, the server 30 transmits to the inspection device 20a predetermined identification operation information generated so that the second hand-washing area 3b is designated as the next hand-washing area in the hand-washing area information (F33), and transmits to the inspection device 20b predetermined identification operation information generated so that the information indicating that the hand-washing area information is the last hand-washing area (F33).

[0095] In this case, a worker who sees the first hand-washing area 3a designated on the display screen 14a of the authentication device 10, which displays predetermined identification operation information, enters the hygiene management space 2, goes to the first hand-washing area 3a (F13), performs an inspection start operation (F14) and a personal identification operation (F15) at the first hand-washing area 3a, and then washes his / her hands with the first soap (F16), and the first operation stage of the hand-washing action becomes the subject of inspection by the inspection device 20a.

[0096] In the inspection device 20a, when it is determined that the first operation stage of the hand washing action satisfies the predetermined operation conditions (Yes in S213), the inspection result etc. is displayed on the display unit 24 so as to include information indicating the second hand washing area 3b designated as the next hand washing area (S214: F47). Note that when it is determined that the first operation stage of the hand washing action does not satisfy the predetermined operation conditions (No in S213), the above-mentioned retry information and the correct hand washing action for the first operation stage etc. are displayed to the worker (S216), thereby encouraging the worker to wash their hands correctly.

[0097] When a worker sees the specified identification operation information specifying the second hand-washing area 3b as the next hand-washing area, he or she moves from the first hand-washing area 3a to the second hand-washing area 3b (F13), performs the test start operation (F14) and the personal identification operation (F15) at the second hand-washing area 3b, and then washes his or her hands with the second soap (F16), and the second operation stage of the hand-washing action becomes the subject of inspection by the inspection device 20b.

[0098] In the inspection device 20b, when it is determined that the second operation stage of the above handwashing operation satisfies the preset operation conditions (Yes in S213), the inspection result and the like are displayed on the display unit 24 so as to include information indicating that it is the last handwashing area (S214: F47). When it is determined that the second operation stage of the handwashing operation does not satisfy the preset operation conditions (No in S213), by displaying the retry information and the correct handwashing operation related to the second operation stage described above to the operator (S216), the operator can be prompted to perform the correct handwashing operation.

[0099] In the server 30, by receiving the inspection results and the like from each of the inspection device 20a and the inspection device 20b, the aggregated inspection results and the like are recorded in the database of the storage unit 32 so as to be associated with the operator ID and the like (F35).

[0100] As described above, in the hygiene management system 1 according to the present embodiment, the handwashing operation to be inspected is divided into a plurality of operation stages, and the inspection device 20 is installed for each operation stage.

[0101] Thereby, even when it is necessary to perform the handwashing operation to be inspected at different locations, by installing the inspection device 20 at each location, for each inspection device 20 according to the predetermined identification operation information received from the server 30, it is possible to inspect the operation stage to be inspected among the handwashing operations.

[0102] Note that the handwashing operation to be inspected is not limited to being divided into two operation stages as described above, and may be divided into three or more operation stages according to the inspection content and the like. Even in that case, by installing the inspection device 20 at the location for each operation stage, the above effects can be obtained.

[0103] The characteristic configuration of the present embodiment in which the above-described handwashing operation to be inspected is divided into a plurality of operation stages and the inspection device 20 is installed for each operation stage can also be applied to other embodiments. For example, when applied to the above-described third embodiment, the characteristic data for each operation stage received from each inspection device 20 can be accumulated by the server 30 and used for personal identification.

[0104] Note that the present invention is not limited to the above-described embodiments, and may be embodied as follows, for example. (1) The present invention is not limited to being applied to the hygiene management system 1 for managing the handwashing operation by an operator who has been personally identified within the hygiene management space 2, and may be applied to a hygiene management system for managing a predetermined operation (for example, an operation using an arm, etc.) by an operator who has been personally identified within the hygiene management space. Further, the present invention is not limited to being applied to the hygiene management system 1 used in the food production line, and may be applied to a system that requires hygiene management, such as a semiconductor production line, for example.

[0105] (2) As the personal identification information transmitted from the authentication device 10 to the server 30, it is not limited to the above-described facial feature point data. For example, facial imaging image data before extraction of facial feature points may be adopted, or other biometric information such as fingerprint information may be adopted. Further, as the personal identification information transmitted from the authentication device 10 to the server 30, for example, a password input by an operation may be adopted.

[0106] (3) As the inspection start operation and the personal identification operation, it is not limited to the operation of changing the number of fingers extended as described above. For example, other operations by the operator's fingers, such as a plurality of types of ways of holding the hand including the front and back of the hand, may be adopted. Further, as the personal identification operation, an operation by one or two or more fingers and the order thereof may be prepared. Further, for example, the inspection start operation may always be a common operation, or the inspection start operation itself may be abolished.
