Please refer to FIG. 1. FIG. 1 is a functional block diagram of the first embodiment of the indoor ultraviolet sterilization system 10 of the present invention. In order to achieve at least one of the advantages or other advantages, an embodiment of the present invention provides an indoor ultraviolet sterilization system 10, which can be used to sterilize and sterilize an indoor space. The indoor ultraviolet sterilization system 10 includes: an ultraviolet generating unit 12, It is used to generate ultraviolet rays for sterilization; the control unit 14 is electrically connected to the ultraviolet generation unit 12; and the smart door lock 16 is electrically connected to the control unit 14; wherein, the control unit 14 is used to receive a sterilization control The signal 20 is used to control the opening and closing states of the ultraviolet generating unit 12 and the smart door lock 16 according to the sterilization control signal 20. In actual use, the smart door lock 16 and the ultraviolet generating unit 12 can be directly or indirectly electrically connected, or other connection methods that can realize corresponding functions.

The control unit 14 can synchronously control ultraviolet rays according to the received sterilization control signal 18 The generating unit 12 and the smart door lock 16. The control unit 14 can synchronously control the states of the ultraviolet generating unit 12 and the smart door lock 16 at the same time. For example, when the smart door lock 16 is closed, the ultraviolet generating unit 12 is activated to generate ultraviolet rays to sterilize the room, or in the ultraviolet generating unit After closing 12, the smart door lock 16 is opened immediately for people to use the sterilized indoor space immediately.

In order to better protect the safety of people in the indoor space, when the control unit synchronously controls the ultraviolet generating unit 12 and the smart door lock 16 according to the received sterilization control signal 18, when the ultraviolet generating unit 12 and the smart door lock 16 are opened and closed There is a certain time difference. When the sterilization control signal 18 received by the control unit 14 is a sterilization start signal, the smart door lock 16 is closed and the ultraviolet generation unit 12 is activated after a set time has passed to generate ultraviolet rays to sterilize the room; when the control unit 14 receives the sterilization control signal When 18 is a sterilization end signal, the ultraviolet generating unit 12 is turned off (sterilization is stopped) and the smart door lock 16 is opened after another set time has elapsed. The set time in the sterilization start signal and the sterilization end signal can be 1 to 2 minutes or other reasonable time, which can be confirmed and set according to actual conditions. In addition, the set time in different sterilization signals can be the same or different.

Please refer to FIG. 2, which is a functional block diagram of the second embodiment of the indoor ultraviolet sterilization system 10 of the present invention. In order to prevent the ultraviolet rays from causing harm to the human body due to the accidental start of the sterilization state, it is necessary to further effectively monitor the conditions of the personnel in the indoor space in real time. The electrical connection is installed in the upper space of the room, such as the ceiling of the room or the upper part of other vertical walls (which can be the connection between the wall and the ceiling). The infrared detection unit 20 can be used to detect whether there are people in the indoor space and send the detection result to the control unit 14. The control unit 14 can synchronously control the ultraviolet generating unit 12 and the smart door lock according to the detection result of the sterilization control signal 18 and the infrared detection unit 20 16. For example, when the infrared detection unit 20 detects that there is no one in the indoor space, the detection result is sent to the control unit 14, and the sterilization control signal 18 received by the control unit 14 is a sterilization start signal, the control unit 14 accordingly The smart door lock 16 is controlled to close and the ultraviolet generating unit 12 is activated to generate ultraviolet rays to sterilize the room.

In one embodiment, the control unit 14 can also automatically start the sterilization schedule according to the detection result of the infrared detection unit 20 received, so that the indoor ultraviolet sterilization system 10 is more intelligent and humane for the sterilization activities of the indoor space. change. Specifically, when the infrared detection unit 20 detects that there are people in the indoor space, it will start the sterilization schedule, and send the detection result to the control unit 14 to remind the indoor space to be sterilized. Subsequently, when the infrared detection unit 20 detects that all the people in the indoor space have left, the sterilization control signal 18 will send a sterilization activation signal to the control unit 14, and then close the smart door lock 16 and activate the ultraviolet generation unit 12 to generate ultraviolet radiation to the indoor space. Perform disinfection and sterilization.

The unit 14 in turn triggers the control unit 14 to control the opening and closing states of the ultraviolet generating unit 12 and the smart door lock 16. In other words, the control unit 14 itself does not control the sterilization time of the system. Depending on the actual situation, the sterilization control signal 18 may originate from a manual switch or other devices capable of transmitting wireless signals.

Please refer to Figure 4, which is a flowchart of the sterilization control method of the indoor ultraviolet sterilization system. In order to achieve at least one of the advantages or other advantages, an embodiment of the present invention provides a sterilization control method, which is suitable for an indoor ultraviolet sterilization system 10, and the indoor ultraviolet sterilization system 10 is used to sterilize and sterilize an indoor space. It also includes an ultraviolet generation unit 12, a control unit 14, a smart door lock 16 and an infrared detection unit 20. The ultraviolet generation unit 12, the control unit 14, the smart door lock 16, and the infrared detection unit 20 are electrically connected. The sterilization control method includes the following steps:

Step (S11): Utilize the control unit 14 to receive a sterilization control signal 18. This sterilization control signal 18 is either a sterilization start signal or a sterilization stop signal.

Step (S12): Use the infrared detection unit 20 to detect whether there are people in the indoor space. The detection result can be sent to the control unit 14 for the control unit 14 to perform subsequent control processing.

Step (S13): When the sterilization control signal 18 received by the control unit 14 is a sterilization start signal, and the detection result is that there is no one in the indoor space, the control unit 14 is used to control the smart door lock 16 to close;

Step (S14): Start the ultraviolet generating unit 12 to generate ultraviolet rays to sterilize the indoor space. This step can be performed by the control unit 14.

Also, in an embodiment, the indoor ultraviolet sterilization system 10 may further include a timer 22, which sets the generation time and sterilization time of the sterilization control signal 18, so as to more accurately control the sterilization start of the indoor ultraviolet sterilization system 10 Time and sterilization time. Specifically, the timer 22 sends a sterilization control signal 18 (such as a sterilization start signal) to the control unit 14 when the sterilization starts, triggers the control unit 14 to start the ultraviolet generation unit 12 and controls the smart door lock 16 to close; the timer 22 is at the sterilization time Send another sterilization control signal 18 at the end (such as the end of sterilization signal) No.) to the control unit 14 to trigger the control unit 14 to turn off the ultraviolet generating unit 12 and control the smart door lock 16 to unlock. In other words, the control unit 14 itself does not control the sterilization time of the system. The user can adjust the sterilization time of the system by setting the time of the timer 22 according to their needs. Depending on the actual situation, the sterilization control signal 18 may originate from a manual switch or other devices capable of transmitting wireless signals.
