Referring to Fig. 1, Fig. 2 and Fig. 3, a wireless anti-theft system includes an anti-theft detector 1 installed in a room, an on-site processing device 2 and an alarm device 3, and the anti-theft detector 1 is connected to the on-site processing device 2 in communication , the on-site processing device 2 includes: a signal receiving module 4 for receiving anti-theft detector signals, an alarm output module 5 for sending an alarm command to the alarm device, and the described anti-theft system also includes a camera installed in the room 6. The mobile phone 7 connected to the on-site processing device 2 through a communication network, and the camera 6 is connected to the on-site processing device 2; the on-site processing device 2 also includes a wireless transceiver for data exchange with the mobile phone Module 8; image collection module 9, for after receiving the anti-theft detector alarm signal, captures the image obtained by the camera at the corresponding position of the detector, and transfers the image collected to the wireless transceiver module; start the alarm module 10, use In receiving the alarm confirmation information of the mobile phone, an alarm signal is sent; the output of the start alarm module 10 is connected to the alarm output module 5; the mobile phone 7 includes an alarm information receiving module 11, which is used to receive the image sent by the on-site processing device; The confirmation module 12 is used for selectively sending alarm confirmation information to the on-site processing device when the user judges whether there is a thief entering according to the image.

The anti-theft system also includes a magnetic control anti-theft sensor 13 installed at the door and window, and the magnetic control anti-theft sensor 13 is connected with the on-site processing device 2 in communication; the described camera 6 is installed next to the magnetic control anti-theft sensor 13 .

Start the alarm module 10 after receiving the alarm confirmation information from the mobile phone 7, start the camera to record the monitoring information of the set time.

The on-site processing device 2 also includes a default alarm module 14 for not receiving the reply command of the mobile phone within the preset time limit, and starts a default alarm module. Timing after the signal of the device or the magnetic control anti-theft sensor, and judging whether the time of not receiving the reply command of the mobile phone exceeds the preset time limit; the default processing unit 16 is used to judge that after exceeding the preset time limit, start the monitoring of the camera record setting time information or send an alarm signal to the alarm output module.

The camera 6 has a recording device 17, and the alarm module 10 starts the recording device 17 to capture the sound information of the preset time; the default processing unit 16 starts the recording device 17 to capture the sound information of the setting time. voice message.

Described on-site processing device 2 also comprises GPRS module 18, short message module 19, and described image acquisition module 9 connects GPRS module 18, and described starting alarm module 10 connects short message module 19, and described GPRS module 18, The short message module 19 is connected with the wireless transceiver module 8; the common mobile phone also includes a GPRS module and a short message module, the described alarm message receiving module is connected with the GPRS module, and the described alarm confirmation module is connected with the short message module. The on-site processing device of the GPRS module sends pictures or video streams to the mobile phone, and the user checks and confirms whether there is any abnormality after receiving it through the mobile phone, and can reply the confirmation message through the short message code. The short message module of the on-site processing device receives the user's short message, select activate the alarm device.

The working process of the present embodiment is as follows: with reference to Fig. 3, assuming that an abnormal signal sent by the infrared anti-theft detector 1 or the magnetically controlled door and window anti-theft sensor 13 is detected, the interruption is triggered, and the central processing module of the on-site processing device 2 responds to the interruption The processing program is to turn on the camera 6, and store the image information obtained by the camera 6 into the storage module of the on-site processing device 2, and record the current time for future inspection or alarm. And send a short message (maybe called "alarm message") to inform the mobile phone (or mobile station) of the situation on the spot, and send the image captured by the camera to the mobile phone, which can be several frames of pictures or sent to the mobile phone in the form of video stream. The mobile phone and the owner of the mobile phone can know whether the situation on the scene is a false alarm or a real thief has entered through the alarm message received and combined with the received picture or video stream. If it is confirmed that there are thieves to enter, then the owner can send a short message to the on-site processing device 2, the content of the short message can be a certain code, such as 0 means to start the alarm device, 1 means to indicate that the camera captures the image and continues for half an hour. The on-site processing device 2 can analyze the code in the received short message and perform corresponding processing according to the agreed method. Assume that the owner sends a text message to instruct the on-site processing device to turn on the alarm, and instructs the camera to continue capturing images for half an hour. Then the on-site processing device parses these instructions, and starts the alarm device 3, so as to intimidate and warn the thieves. At the same time, the camera 6 and the recording device 17 will capture the view and sound of this process, and store the recorded information in the memory of the on-site processing device. , for later viewing. Of course, after the owner confirms that a thief has entered, he can also report to the public security organ.

If the on-site processing device 2 does not receive the short message instruction sent by the mobile station within a certain long period of time, it will process the site according to the pre-default program. For example, the images and sounds within the current 10 minutes are recorded, and the recorded information is stored in the memory of the on-site processing device for subsequent viewing. The camera and recording device are then turned off so that they can only be restarted under a new command from the field processing device.

Alarm device 3 can also be activated when the on-site processing device detects an abnormal signal, which can scare off thieves in time. The timing of the alarm depends on the specific requirements of the user.

The anti-theft detector can also be integrated with the camera, and the image captured by the camera can be processed in the on-site processing device to identify whether there is a moving object in the current monitoring area, that is, it can identify whether someone is active in the space monitored by the camera. If there is, an alarm signal is activated, and the on-site processing device sends the current situation to the mobile phone through a short message, and at the same time sends the current image or video stream to the mobile phone or the monitoring center, and the user confirms whether there is any abnormality through the mobile phone.
