Problems solved by technology
The main defect of this alarm device has two: one is that the investment is relatively large, which exceeds the economic bearing capacity of most families and units.
[0003] Most of the prior art family anti-theft alarm devices including the above-mentioned patents are: (1) using password or coding as the control terminal, its circuit is more complicated, and there are many intermediate links, which are prone to false triggering and contact failure
(2) More analog circuits are used, less digital circuits are used, and the recognition time is longer, which reduces the reliability of the anti-theft device and is prone to false alarms
(3) Troublesome to use, high cost, poor optionality and damage resistance

Embodiment Construction
[0019] The content of the present invention will be described in detail below with reference to the embodiments shown in the drawings, including the arrangement and installation structure, electrical principles and operation control methods of the components of the home anti-theft alarm device with mutual assistance function.
[0020] see first figure 1 and figure 2 , the device of the present invention comprises two parts, promptly is installed in the user's home detection dial code call part I and is installed in the judgment control alarm part II of user's neighbor's home, and two parts are electrically connected as a whole with communication cable 3. Detect dial code call part I to comprise many pairs of magnetic steel 1-magnetic sensor 8, two dial dials 9 and 10, transformer 30 (see image 3 , figure 1 and figure 2 Not shown in), rectifier 32, emergency call button 12, local alarm 13. The judgment control alarm part II includes a digital control circuit board 880 wi...

This invention provides a kind of family anti-theft alarm apparatus and its operation and control method that with the mutual help function. This apparatus includes the detection and dial calling part that installed in user's family and judge and control alarm part that installed in user's neighbor family. The two parts link with each other. The detection and dial calling part consists of multiple pairs of magnetic steel - magnetism sensor that installed on door (window) and its frame, the dial and the alarm. The judge and control alarm part consists of digital control circuit board with the core of SCM, standby battery and calling alarm. One can compile the working program by assembly language. The master program and subprogram nested with each other to realize alarm by interrupt program.
Description
technical field [0001] The invention relates to a family anti-theft alarm device with a mutual assistance function, which is mainly composed of a magnet, a magnetic sensor, a single-chip microcomputer and a dial. Background technique [0002] There are two types of home anti-theft alarm devices: centralized distributed and non-centralized. Existing family anti-theft alarm devices adopt centralized distribution more at present, promptly have a central room to monitor each room or family, and its sensor adopts infrared sensor more. The main defect of this alarm device has two: the one is that investment is bigger, has exceeded the economic bearing capacity of most families and units. The second is poor personal choice. That is to install or not to install, what kind of alarm device to install is not determined by one or two families. And some non-centralized anti-theft alarms, such as U.S. Patent 4,335,376, although they overcome the above-mentioned shortcomings in design, ...
