In comparison with the main area 10, the extended area may not be provided with one of the disinfecting devices 140_1-140_m. In the embodiment of FIG. 2, the main area 10 is provided with the disinfecting device 140_1 and the recognition device 130_1, the extended area 20A is provided with the disinfecting device 140_2 and the recognition device 130_2, and the extended area 20B is provided with the alerting device 150 and the recognition device 130_3.

Referring to FIG. 3, FIG. 3 is a flow diagram of a personnel tracking and disinfecting method 200 in accordance with some embodiments of the present disclosure. The personnel tracking and disinfecting method 200 can be executed by the central controller 110 of FIG. 1 or 2. However, the present disclosure is not limited herein. For better understanding the present application, the personnel tracking and disinfecting method 200 would be described below with reference to FIGS. 2-3. As shown in FIG. 3, the personnel tracking and disinfecting method 200 includes operations S201-S210.

In operation S201, the central controller 110 controls the recognition devices 130_1-130_n to recognize the person in the place 1. In operation S202, the central controller 110 determines whether the person in the place 1 is in the main area 10 or in the extended area (i.e., the central controller 110 determines the position of the person in the place 1 by cooperating with the recognition devices 130_1-130_n).

In some embodiments, if the person is in the main area 10, the recognition device 130_1 in the main area 10 can recognize the person and transmit the recognition result to the central controller 110. Accordingly, the central controller 110 can search the recognition device database according to the identification information of the recognition device 130_1, so as to obtain that the recognized person is in the main area 10. In other embodiments, if the person is in the extended area 20A or 20B, the recognition device 130_2 or 130_3 in the extended area 20A or 20B can recognize the person and transmit the recognition result to the central controller 110. Accordingly, the central controller 110 can search the recognition device database according to the identification information of the recognition device 130_2 or 130_3, so as to obtain that the recognized person is in the extended area 20A or 20B. In brief, the central controller 110 can search the recognition device database according to the identification information of the recognition device which transmits the recognition result, so as to obtain the position of the recognized person.

In operation S203, if determining that the person is in the main area 10, the central controller activates the disinfecting device 140_1 in the main area 10 to disinfect the person in the main area 10. In operation S204, the central controller 110 generates the disinfecting record based on the recognition result generated by the recognition device 130_1 in the main area 10. In some embodiments, the central controller 110 obtains the person identity of the recognized person according to the recognition result generated by the recognition device 130_1 and further obtains the disinfecting time and the disinfecting location of the recognized person according to the disinfecting device 140_1 operating in the main area 10, so as to generate the disinfecting record.

In operation S205, the central controller 110 stores the disinfecting record in the personnel disinfecting record database. In some embodiments, the central controller 110 searches the personnel disinfecting record database according to the person identity in the disinfecting record generated currently, so as to determines whether a previous disinfecting record of the recognized person is stored in the personnel disinfecting record database. If the previous disinfecting record of the recognized person exists, the central controller 110 updates the disinfecting time and the disinfecting location in the previous disinfecting record according to the disinfecting record generated currently. If the previous disinfecting record of the recognized person does not exist, the central controller 110 adds the disinfecting record generated currently to the personnel disinfecting record database.

In operation S206, if determining that the person is in the extended area, the central controller 110 determines whether the person in the extended area has the disinfecting record. In some embodiments, the recognized person is in the extended area 20A as shown in FIG. 2. Accordingly, the central controller 110 obtains the person identity of the recognized person according to the recognition result generated by the recognition device 130_2 and searches the personnel disinfecting record database according to the person identity of the recognized person, so as to determine whether a previous disinfecting record of the recognized person is stored in the personnel disinfecting record database.

In operation S207, if determining that the person in the extended area 20A has the disinfecting record, the central controller 110 further determines whether the person in the extended area 20A satisfies a disinfecting standard. In some embodiments, the central controller 110 calculates an elapsed time according to a previous disinfecting time in the previous disinfecting record stored in the personnel disinfecting record database. For example, the central controller 110 subtracts the previous disinfecting time from a current time to calculate the elapsed time. After calculating the elapsed time, the central controller 110 compares the elapsed time with a first predetermined time (e.g., 1 hour).

If the elapsed time does not exceed the first predetermined time (i.e., satisfies the disinfecting standard), the central controller 110 executes operation S208. In operation S208, the central controller 110 does not disinfect the person in the extended area 20A. In other words, the central controller 110 does not activate the disinfecting device 140_2 in the extended area 20A. If the elapsed time exceeds the first predetermined time (i.e., does not satisfy the disinfecting standard), the central controller 110 labels the person in the extended area 20A as needing disinfection (for example, adds information and/or label related to “needing disinfection” to the disinfecting record of the person in the extended area 20A) and executes operation S209 simultaneously. In operation S209, the central controller 110 disinfects the person in the extended area 20A by activating the disinfecting device 140_2 in the extended area 20A.

In other embodiments, the previous disinfecting record of the recognized person further includes an execution time. In some practical applications, the recognized person was irradiated by the ultraviolet light irradiation device (i.e., one of the disinfecting devices 140_1-140_m) for 3 seconds before entering the extended area 20A, and therefore the execution time recorded in the disinfecting record by the central controller 110 is 3 seconds. Accordingly, in operation S207, the central controller 110 determines whether the execution time in the previous disinfecting record exceeds a second predetermined time (e.g., 5 seconds), so as to determine whether the person in the extended area 20A satisfies the disinfecting standard.

If the executed time exceeds the second predetermined time (i.e., satisfies the disinfecting standard), the central controller 110 executes operation S208. If the executed time does not exceed the second predetermined time (i.e., does not satisfy the disinfecting standard), the central controller 110 labels the person in the extended area 20A as needing disinfection and executes operation S209 simultaneously. The description of operations S208 and S209 are similar to those of above embodiments, and therefore are omitted herein.

In operation S210, the central controller 110 generates the disinfecting record and stores the disinfecting record in the personnel disinfecting record database. For example, the central controller 110 obtains the disinfecting time and the disinfecting location of the recognized person according to the disinfecting device 140_2 operating in the extended area 20A and updates the disinfecting time and the disinfecting location in the previous disinfecting record according to the person identity obtained in operation S206.

In another embodiment, the central controller 110 determines that the person in the extended area 20A does not have the disinfecting record in operation S206, so as to control the disinfecting device 140_2 in the extended area 20A to disinfect the person in the extended area 20A (i.e., operation S209). In operation S210, the central controller 110 obtains the disinfecting time and the disinfecting location of the recognized person according to the disinfecting device 140_2 operating in the extended area 20A and generates the disinfecting record based on the person identity obtained in operation S206, the disinfecting time and the disinfecting location. Then, the central controller 110 adds the disinfecting record generated currently to the personnel disinfecting record database.

In another embodiment, the central controller 110 determines the recognized person is in the extended area 20B as shown in FIG. 2 in operation S202, and determines that the person in the extended area 20B requires to be disinfected in operation S206 or S207. Accordingly, operation S209 is executed. As shown in FIG. 2, since the extended area 20B is not provided with the disinfecting device, the central controller 110 controls the alerting device 150 to inform the person in the extended area 20B to go to other nearby extended area (for example but not limited to the extended area 20A) which is provided with the disinfecting device, so as to disinfect the person by the disinfecting device in other extended area. Then, the central controller 110 generates the disinfecting record and stores the disinfecting record in the personnel disinfecting record database (i.e., operation S210). The description of operation S210 is similar to those of above embodiments, and therefore is omitted herein. In some embodiments, the alerting device 150 can be implemented by speaker, display or other suitable output devices, so that the central controller 110 may inform person in the place 1 by playing audio and/or video.

In yet another embodiment, the person in the place 1 further passes through at least one other area (not shown) before entering the extended area 20A or 20B (or other extended area), and the central controller 110 determines that the person in the extended area 20A or 20B requires to be disinfected. Accordingly, the central controller 110 can further control the disinfecting device arranged in the at least one other area to disinfect the at least one other area. In other words, the central controller 110 can disinfect the path along which the person moves before entering the extended area, so as to further reduce the disease infection risk.

In sum, by the recognition devices 130_1-130_n and the disinfecting device 140_1-140_m arranged pervasively in the place 1, the personnel tracking and disinfecting system 100 and the personnel tracking and disinfecting method 200 of the present disclosure disinfect person in the place 1 and generate the disinfecting record of the person. In addition, the personnel tracking and disinfecting system 100 can further determine whether the person in the place 1 is disinfected or satisfies the predetermined disinfecting standard according to the disinfecting record stored in the database, so as to activate the disinfecting device selectively.

Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein. It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the invention.
