FIG. 1 is a schematic structural diagram of an image monitoring system with authority classification according to an embodiment of the present invention. Referring to FIG. 1 , an image monitoring system with authority classification includes an inductive device 10 and an imaging device 40 . The video device 40 can be a device such as a camera or a camera that can take a movie or a photo. In some embodiments, the sensing device 10 and the imaging device 40 can be integrated. The sensing device 10 includes a sensing unit 11 and a management unit 12, and the sensing unit 11 and the management unit 12 are connected to each other. The sensing unit 11 can read the identification information of a carrier according to a sensing operation. Here, the carrier is exemplified by the inductive tag 20. However, the embodiment of the present invention is not limited thereto, and the carrier may also be a human body, and the identification information is a biological feature such as a fingerprint, an iris, and the like.

Each of the inductive tags 20 is provided with an antenna circuit and a storage chip, which can be passive inductive tags without the need for a battery. When the user approaches the inductive tag 20 to the sensing device 10, the sensing device 10 can transmit energy to the inductive tag 20, and the antenna circuit on the inductive tag 20 can form an induced current to obtain power, and store the identification information in the chip. The process is transmitted to the sensing device 10 via an antenna circuit, and this process is hereinafter referred to as a single sensing operation. Each of the inductive tags 20 has non-repeating identification information, such as a unique code (such as a MAC code). In other words, each of the sensing tags 20 can be held by different users to further enable the sensing device 10 to know the corresponding user based on the identification information. The aforementioned sensing operation is achieved by wireless sensing technologies such as radio frequency identification (RFID) and near field communication (NFC). In one embodiment, the inductive tag 20 can be an active inductive tag with a battery. The inductive tag 20 can exist independently, such as in the form of a card, a key ring, etc.; it can also be combined with other devices, such as a mobile phone. The carrier (such as the inductive tag 20 or the user) is a hierarchical group of multiple rights. The sensing tags 20 of different permission levels can be inductively operated to form different combinations. When there are N pieces of identification information, there can be 2 ^N combinations. Conversely, when there are N combinations, the identification information has 2 ^N -1 available. Each combination can perform a specific high-privilege action. Here, N is greater than or equal to 1.

The management unit 12 can obtain the read identification information and the privilege level to which it belongs. As shown in FIG. 1 , the sensing device 10 further includes a storage unit 14 that stores a level comparison table, and the level comparison table records the permission level corresponding to each identification information. Thereby, the management unit 12 can find the permission level corresponding to the read identification information in the hierarchical comparison table. The storage unit 14 can be a storage medium such as a flash memory, a hard disk, or a memory card.

The management unit 12 performs a low-right action when it is recognized as a single-sensing operation, and performs a high-right action when it is recognized as a multi-induction operation. Here, the single sensing operation is one sensing operation of one sensing tag (there is no other sensing operation within a preset time after the sensing operation). The multiple sensing operation is performed by a sensing operation of the sensing tag of the first privilege level, and then by one sensing operation of the sensing tag of at least one second privilege level (the interval time of each sensing operation is less than a preset time) ), here, the first privilege level is a higher privilege level, and the second tier level is a lower privilege level. However, in some embodiments, the first privilege level may be a lower privilege level and the second tier level is a higher privilege level. The following will be exemplified by a second privilege level for the lower privilege level.

As shown in FIG. 1, the sensing device 10 further includes a timing unit 13 connected to the management unit 12 to recognize that the sensing operation is a single sensing operation or a multiple sensing operation. Specifically, each time the management unit 12 receives the identification information, the timing unit 13 is driven to count a preset time, and if the repeated identification information is received within the preset time (that is, the identification information is the same as the previous sensing operation), Another preset time will be counted again. If the same identification information is received within the preset time, the preset time is counted again, and another different identification information is received within the preset time, and the management unit 12 recognizes For multiple sensing operations. On the other hand, if no identification information is received within the preset time period after receiving the identification information, the management unit 12 recognizes that it is a single sensing operation. The preset time may be 1 second, 5 seconds, or 30 seconds, etc., and the present invention is not limited thereto. In addition, the length of the preset time can be adjusted according to needs. Here, the management unit 12 also determines the number of times of the sensing operation of the repeated identification information. If it is greater than or equal to the preset number of times, and then receives another identification information, the management unit 12 determines that the multiple sensing operation is performed. Here, the preset number of times can be adjusted according to the demand. In addition, the management unit 12 also checks the privilege level of the received identification information, and if the grading level is met, the high privilege action is executed.

Under the single sensing operation, the management unit 12 transmits the read identification information to the servo device 30 via the communication unit 15 for storage by the servo device 30 as an attendance information (low authority operation), that is, the servo device 30 is identified according to the identification. The information records the identity of the attendants and the time of attendance. The servo device 30 can further confirm whether the departure time is correct, the order of the departure is correct, whether the driver is correct, or other information for controlling the driver or the vehicle according to the attendance information. The confirmation result can be further transmitted back to the sensing device 10. When the inductive tag 20 held by the field personnel is incorrect, the sensing device 10 can promptly prompt the field personnel according to the confirmation result transmitted by the servo device 30 to prevent the field personnel from driving out. Under the multiple sensing operation, the control personnel perform multiple sensing operations, and then the field personnel perform an inductive operation on the sensing tag 20 held by the field personnel, so that the sensing unit 11 recognizes the multiple sensing operations and obtains higher authority. Identification information for levels (management personnel) and lower authority levels (field personnel). Then, the management unit 12 transmits the read identification information of the higher authority level and the identification information of the lower authority level to the server device 30 via the communication unit 15 for storage by the server device 30 as an audit and attendance information (high authority) action). That is, the servo device 30 records the identity of the attendant and the attendance time (ie, the attendance information) according to the identification information of the lower authority level, and records the identity of the manager (ie, the audit information) according to the identification information of the higher authority level. In this way, the control personnel can first check the mental state of the field personnel, avoid drunk driving, fatigue driving, and also confirm whether it is the correct rotation outside the personnel, after the inspection is passed, perform the aforementioned multiple sensing operations. In addition, since the servo device 30 records the attendance information, if the attendance personnel do not return within the predetermined time, the servo device 30 can actively notify the controller to perform tracking.

The image taken. The image can be a historical image or an instant image with a few seconds of error. The high-privileged action performed by the management unit 12 is to transfer images to the servo device 30 via the communication unit 15 for backup. Here, the image transmitted by the high-rights action can record the image for the trigger event in the most recent predetermined period (such as one day), or within a predetermined period (such as within one day, three days, one week, one month) ) Recorded images. In some embodiments, the image transmitted by the high-rights operation may be additionally transmitted to the electronic device 50 for the electronic device 50 to play the transmitted image. After receiving the image to be backed up, the servo device 30 may additionally upload the image to other devices. Server (such as video playback website). In this way, the user who has different rights can perform different treatment on the image captured by the image device 40 through the high-privileged action and the low-privileged action.

FIG. 3 is a schematic structural diagram of an image monitoring system with a privilege leveling according to another embodiment of the present invention. Compared with FIG. 1, the system further includes a locking unit 16 for locking the storage unit 14 to Avoid arbitrarily taking the storage unit 14 away. After the foregoing multiple sensing operations (the sensing operation is performed by both the controller and the operator), the high-privileged action performed by the management unit 12 is to release the locking unit 16 locked to the storage unit 14 so that the manager and the operator can take it away. The storage unit 14 is for offline backup. Here, the locking unit 16 can be an electronic lock or other type of lock.

In one embodiment, the communication unit 15 supports wireless network (Wi-Fi) communication, and the connection of the electronic device 50 to the wireless network can be managed through the privilege hierarchy as described above. Here, the high-privileged action is to allow the electronic device 50 to connect to the communication unit 15 in a Wi-Fi Protected Setup (WPS) program. Alternatively, the high-privileged action is to transmit a time-limited Internet access setting to the electronic device 50 via the sensing unit 11, so that the electronic device 50 can obtain time-sensitive Internet settings (such as an account number and a password) for connecting to the communication unit 15. In this way, through the high-privileged action, the image monitoring system can be put into the engineering mode, and the engineer can be connected and connected to the sensing device 10 and the imaging device 40 through the electronic device 50 to perform setting and installation by the user, so that the system It can balance safety and convenience.

For example, when the security personnel go to the household, the sensor tag 20 held by the security personnel is only for the sensing device 10 to read, and only the sensing device 10 can be set (ie, low-privileged action), and the door of the household cannot be opened ( That is, the permission level of the sensor tag 20 held by the security personnel cannot perform the high authority action). Therefore, the monitoring personnel at one end of the servo device 30 can operate the servo device 30 according to the on-site demand (if the resident is not at home but has an abnormal warning), and the servo device 30 can generate an authorization command, which is received by the communication unit 15 of the sensing device 10. . Thereafter, the security personnel hold the sensing tag 20 to cause the sensing unit 11 of the sensing device 10 to read the identification information, and the management unit 12 can open the door lock of the household (ie, the high authority action) according to the authorization command. In other words, the server device 30 generates an authorization command to temporarily authorize the original sensor tag 20 to perform a high-privileged action that could not be performed. Thereby, the permission level of the identification information of the sensing tag 20 can be temporarily changed at the remote end, and when the security personnel complete the task, the original authority is restored.

In an embodiment, the image monitoring system is also applied to the access control. When the sensing unit 11 reads the identification information, the management unit 12 can drive the image device 40 to take a picture or video for verification. If the management unit 12 recognizes that the identification information is legal, the door lock can be opened.

Here, the image device 40 may have an infrared motion sensor or other motion sensor to detect a person staying within the sensing range. The management unit 12 can receive the detection signal of the image device 40 to know the proximity of the person, the dwell time, and the moving speed. The timing unit 13 can time a legal residence time. If the person stays longer than the legal residence time, the sensing unit 11 When the identification information that does not read the authority is read, it will be recognized as a stranded person event. When the resident personnel event is detected, the management unit 12 transmits an event notification to the server device 30 via the communication unit 15, so that the management center where the server device 30 is located can be immediately strained, and the management unit 12 can also be via the communication unit 15 The image containing the resident is backed up to another adjacent image device 40, so that even if the image stored by the image device 40 or the sensing device 10 is deleted, the image of the resident person can be found in the other imaging device 40.

That is to say, when the trigger unit 17 is triggered, the management unit 12 will perform the identification of the multiple sensing operations; when the trigger unit 17 is not triggered, the management unit 12 will perform the identification of the single sensing operation. After the multiple sensing operation has been performed, it will be considered that the trigger unit 17 is in an untriggered state. Conversely, when the trigger unit 17 is triggered, the management unit 12 will perform the identification of the single sensing operation; when the trigger unit 17 is not triggered, the management unit 12 will perform the identification of the multiple sensing operations. After a single sensing operation has been performed, it will be considered that the triggering unit 17 is in an untriggered state. Compared with the first privilege level of the foregoing embodiment, multiple sensing operations are required to identify multiple sensing operations, and the sensing system of the first privilege level and the second privilege level in this embodiment can be sensed only once.
