Embodiment Construction

[0010] Now in conjunction with the accompanying drawings, the technical content, especially the working principle, of the present invention will be described in detail.

[0011] 1. Initial state:

[0012] 1. Before going out, store the owner's mobile phone number in the phone;

[0013] 2. Turn on the power supply of the control circuit of the present invention;

[0014] 3. Carefully check whether the doors and windows are effectively closed, that is, whether the micro switches XK1, XK2...XKN are in the normally open state;

[0015] 4. Use the key to turn the key button K0 to the closed position.

[0016] 2. Anti-theft process: (Assume that the thief enters the room from the window where the micro switch XK1 is installed)

[0017] 1. When XK1 is closed, the coils of J1, J2 and SJ1 are electrified and work. At this time, if the thief disconnects XK1 (closes its window), but due to the self-locking function of J2-4 normally open contact closure, J1, J2 and SJ1 can still be gu...

Abstract

This circuit consists of the phone, the key button, the intermediate relay, the time relay and the micro switch, etc. The existing various anti-thief door, locks, metal line net are easy to be broken while the alarm and TV monitor cannot catch thief on field. This circuit overcomes these shortages and fully uses the mobile net. When stealing occurs, the phone sends in time the repeated soundless alarm signal to the master's handset. It can catch the thief. Its anti-thief effect is good and cost low. It possesses society benefit and is valuable to extend.

Description

technical field [0001] The invention relates to a telephone alarm control circuit for anti-theft devices such as homes, offices and business places, property rooms and warehouses. Background technique [0002] Preventing public or private property from being stolen is one of the issues that every unit, enterprise and family focuses on. At present, anti-theft devices such as various anti-theft doors, anti-theft locks, anti-theft gates, anti-theft nets, anti-theft alarms, and TV monitors have been widely used, but they still have some shortcomings: ① Thieves may destroy anti-theft doors and locks by using some special tools. , gates, and nets, causing property to be looted, causing harm or loss to collectives and families. 2. alarm and monitor can not realize the ultimate purpose of capturing the thief on the spot. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned similar technologies, the present invention utilizes a telephone alarm cont...
