In the following detailed description of the present invention, certain specific details are set forth. It will be apparent to one skilled in the art that the present invention may be practiced without these specific details. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention. Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.
Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to". In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
Fig. 1A is a schematic diagram of a wireless network based anti-theft system according to an embodiment of the present invention. Fig. 1B is a schematic layout diagram of the anti-theft system according to the embodiment of the present invention. As shown in fig. 1A and 1B, a wireless network based antitheft system 1 of the present embodiment includes a plurality of wireless network terminal detection devices 1 and an identification information processing device 2. The wireless network terminal detection devices 1 are respectively arranged at different positions and are suitable for automatically acquiring the identification of the wireless network terminal A entering a communication range. The identification information processing device 2 is in communication connection with the plurality of wireless network terminal detection devices 1 and is used for judging whether an anti-theft alarm needs to be performed or an anti-theft device needs to be started according to all the currently acquired identifications. The identification information processing device 2 may be installed together with the plurality of wireless network terminal detection devices 1 or installed together in the anti-theft area, or may be installed in another location outside the anti-theft area.
In this embodiment, the wireless network may be any existing commonly used wireless communication network, and may be set as a specific wireless network according to different application scenarios or in consideration of cost. For example, in view of the general availability, probing may be performed for Wireless Local Area Network (WLAN) terminals (i.e., terminals that comply with the IEEE802.11 family of protocols). Also for example, in view of the general use, the detection may be performed for a bluetooth terminal.
With the wide application of smart devices such as smart phones and tablet computers, almost all people carry with them similar smart devices. These devices typically have a wireless network (e.g., a wireless local area network and a bluetooth network as described above) to connect. Before connecting to the wireless network, the wireless network terminal needs to perform a handshake operation, that is, after the communication circuit is established, before information transmission begins, information exchange of communication parameters and other protocol characteristics is achieved. In some cases, the wireless network terminal broadcasts its own information to obtain the necessary connection response in different ways, and in other cases, the wireless network terminal scans and receives the external broadcast information to obtain the information of the access point or the connecting party and automatically responds to the information. By utilizing the specific requirement of exchanging the identification in the connection handshake process, the wireless network terminal detection device of the embodiment of the invention can acquire the identification of the wireless network terminal by actively scanning the information corresponding to the terminal or directly receiving the terminal broadcast. Due to the uniqueness of the identification, the identity of a person entering or in a communication range area can be automatically judged according to the uniqueness, and then corresponding operation is carried out.
Fig. 2A is a schematic flow chart of performing radio network terminal identity detection. As shown in fig. 2A, in the figure, the wireless network terminal detecting device 1 broadcasts its own identification and connection information. After receiving the identification and the connection information, the wireless network terminal entering the communication range automatically initiates a handshake flow, expecting to establish data connection. In this process, the radio network terminal sends its own identity to the radio network terminal detection apparatus 1.
Fig. 2B is a schematic flow chart of radio network terminal identity detection in another scenario. As shown in fig. 2B, some wireless network terminals actively broadcast a probe request (probe request), which usually carries identification information of the probe request. At this time, the wireless network terminal detection devices within the communication range can detect the identities thereof.
In this embodiment, the wireless network terminal detection device may be a specially configured detection terminal. Preferably, the wireless network terminal detection device may also be a wireless network access device for wireless network coverage, such as a wireless bridge, a wireless access point, a wireless router, and the like. When the wireless access device is used as a wireless network terminal detection device, the wireless access device gives consideration to both theft prevention and wireless network coverage, can better utilize the existing hardware and reduce the system installation cost.
The identification information processing device 2 and the plurality of wireless network terminal detection devices 1 store a preset predetermined identification group. The predetermined set of identities is used to characterize identities of wireless network terminals of persons legally moving within the coverage area of the anti-theft system, e.g. identities of wireless network terminals of house owner family members. Thus, the identification information processing device 2 obtains the identifications of all wireless network terminals present in the coverage area of the current wireless network signal through the plurality of wireless network terminal detection devices 1. If there are identifiers belonging to a predetermined group of identifiers among all identifiers, it is stated that although there may be others in the room, persons who are legally able to move in the area are accompanied by each other, which is usually the normal situation, without the need to perform burglar alarms or activate other antitheft devices. If all the identifiers do not belong to the preset identifier group, the situation shows that persons who can legally move in the area are not in the area, and the persons in the area are possibly illegal to enter the area, and an anti-theft alarm needs to be carried out or other anti-theft devices need to be activated. The above determination may be performed simultaneously in one step, or may be performed stepwise in a plurality of steps. For example, whether the currently acquired identifier meets the above condition that an anti-theft alarm needs to be performed or an anti-theft device needs to be activated may be periodically determined, and if so, corresponding operations are performed. For another example, it may be periodically determined whether a flag belonging to a predetermined flag group exists in the current flags at a first period, and if so, the state flag may be set to a disarming state, and if not, the state flag may be set to a arming state. And if the current state is the defense state, periodically judging whether the acquired identifiers have identifiers outside the preset identifier group or not according to a second period, and if so, performing alarm operation.
Preferably, when a person holding the wireless network terminal moves in a large area, the wireless network terminal may directly switch between different wireless access points, and meanwhile, the signal strength received by the same wireless access point or multiple wireless access points may also change. On this basis it can be detected whether a specific wireless network terminal is moving and enters a predetermined sub-area.
Thus, the identification information processing device is configured to alarm when a specific wireless network terminal detection device (for example, a wireless network terminal detection device provided in a financial room) acquires an identification that does not belong to a predetermined identification group.
Meanwhile, based on whether the wireless network terminal belonging to the predetermined identity group does not move for a long time, it may be determined whether the user is asleep or leaves the wireless network terminal within the area. The identification information processing apparatus may enter a defense state when such a situation is detected, and alarm when an identification that does not belong to a predetermined identification group is detected again. Therefore, the alarm can be more accurate.
The invention utilizes the popularity of the mobile communication terminal with the function of wireless local area network access or Bluetooth access and the characteristic that people usually carry the mobile communication terminal with them to detect and collect the identifications of all wireless network terminals entering the communication area in an active or passive mode. And judging the identity of the entrant according to the identification of the terminal so as to judge whether an anti-theft alarm needs to be carried out or an anti-theft device needs to be started. If the wireless network terminal belonging to the predetermined identification group is within a communication range (i.e., indoors), it is determined that the homeowner is at home, otherwise, it is determined that the homeowner is not at home. If other wireless network terminals appear in the communication range when the house owner is not at home, the fact that a stranger enters is indicated. Due to the comprehensiveness of wireless communication coverage, the anti-theft system can provide better anti-theft coverage effect, does not need a user to perform special arming or disarming operation, and is convenient to use.
Fig. 3 is a schematic diagram of a wireless network based theft prevention system according to another embodiment of the present invention. The antitheft system shown in fig. 3 includes a plurality of wireless network terminal detection devices 1 and an identification information processing device 2. Meanwhile, the antitheft system further includes a plurality of moving object detection devices 3. In this embodiment, the moving object detecting device may be, for example, a camera, an infrared monitoring device or an infrared anti-theft device, which is disposed at different positions of the anti-theft area, and may detect whether there is a moving object by means of an image or a sensor. In this embodiment, in order to improve the accuracy of the burglar alarm, the information acquired based on the wireless network terminal detection is used as a part of conditions for triggering the burglar alarm or starting the burglar alarm, and the moving object detection device 3 is used to assist the burglar detection.
Specifically, the identification information processing device 2 is connected to the moving object detecting device 3, and is configured to control the moving object detecting device to start when no identification (no person in the area) is currently acquired or no identification in any one predetermined identification group is detected (all persons in legal activity leave). For example, the identification information processing device may enter a defense state and activate the moving object detection device 3 when detecting the above situation. Thereby, it is possible to prevent a person who does not carry the wireless network terminal from entering the antitheft area without being found. In the armed state, if the moving object detection device 3 detects a predetermined signal (i.e., detects a moving object), it indicates that there is a possibility of illegal entry and an alarm needs to be given.
It is easy to understand that the alarm operation includes automatically sending a message (short message or data message) to a predetermined location, automatically dialing a predetermined telephone, pushing an alarm message, and triggering sound, light and electric devices in a room to prompt.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
