As described in the background art, building and home intelligent anti-theft alarm systems in the prior art all adopt identity recognition systems, and the identity recognition systems are used for comparing visual, portrait, fingerprint passwords and other verification modes formed by various sensors, then identifying and verifying visitors, and finally carrying out the next step of instruction; two alarm modes are provided, one mode is that a sound-light alarm system is arranged at a place where the identity recognition system is arranged, so that the effect of frightening is achieved; secondly, the signal is transmitted to an upper computer to inform the host; however, when the communication network is interrupted or damaged accidentally, only sound and light alarm can be achieved, but the deterrence force is not enough, and the purpose of anti-theft alarm cannot be achieved; therefore, a method capable of achieving the purpose of early warning when the identity recognition system is damaged consciously is needed, and the following specific disclosure scheme is solved.
The invention discloses an anti-theft alarm method of a double-independent system, please refer to fig. 1, which comprises a first device and a second device which are independently installed, wherein the independent installation means that the link of the first device does not need to be associated with the second device, so that the first device has communication capability and alarm capability under the general impression, the second device does not have too high attention, the identification range of the second device is not overlapped with the first device, and the state of the first device is monitored, so that the aim of early warning can be further fulfilled; the anti-theft alarm method comprises the following steps:
the first device collects identity identification information;
judging whether the identity is in accordance with the specified identity according to the identity identification information, and if the identity is not in accordance with the specified identity, giving out an audible and visual alarm; firstly, ensuring that the basic functions of the access control can be used;
the second device collects first depth image information within a first threshold range, wherein the first threshold range comprises an image of the position where the first device is located; the depth image information is three-dimensional information data of an image in an actual scene stored in a pixel of a photo and can be obtained by shooting through a depth camera;
analyzing whether the first depth image information contains specified small target image information; the small target object is identified by combining a characteristic extraction mode with a mode of an SSD (solid State disk) convolution neural algorithm, and the characteristic identification can be used for judging the small target and identifying specific dangerous goods such as a cutter, a tool clamp, a flame and the like;
if the first depth image information contains small target image information, entering a pre-alarm state; so-called pre-alarms are only the first heavy emergency state, since the primary alarm function can be issued without the first device being destroyed, then the second device does not have to transmit, but when the first device is intentionally destroyed, the destructive tool and the resulting sparks can be identified by the second device, and then in combination with the alarm sound or warning flash directly issued by the first device, an upload of a signal is made to notify the user;
and when the information of the acousto-optic alarm is simultaneously acquired in the pre-alarm state, the information is uploaded and the alarm is sent.
In this embodiment, when the second device analyzes the first depth image information, a convolutional neural network is used to extract and identify the small target image information.

but if the feedback signal is not received within the third time threshold period, information is uploaded and an alarm is sent.
In this embodiment, the small target image information includes a picture of the characteristics of the flame, the knife, and the tool holder. Since image recognition used in the prior art has high accuracy when it is applied to a large target object although there is also feature recognition, it is necessary to specifically select a small target that threatens the first device for recognition.
In the implementation process, the first device is installed as an access control system, so that identification of visitors, masters and unexpected situations is realized under normal operation, and prevention and anti-theft alarm under normal conditions are realized; the second device is another independent system away from the first device, which is mainly used for preventing and controlling the condition of the space where the first device is located, and the second device is operated in an own set of modes; only performing preventive monitoring on the premise that the first device can normally operate; however, when the first device is in an audible and visual alarm or the first device is in a pre-alarm state and does not respond to communication, the second device alarms to the upper computer to ensure the function of effective alarm in emergency.
