Anti-theft device with integrated telephone alarm

Abstract

The invention provides an anti-theft device with an integrated telephone alarm, belonging to the technical field of anti-theft. The anti-theft device is formed by a contact piece, a warning start circuit, a lock switch, a field warning circuit, a radio multi-code transmitter circuit, and the integrated telephone alarm. When a hand touches the contact piece, a touch signal is generated, after the signal is amplified by the warning start circuit, the field warning circuit is started to emit warning, if stop is failed, the contact piece is loose, the lock switch immediately emits an alarm start signal, while the field warning circuit is started, the radio multi-code transmitter circuit with strong interference resistance and reduction of weather and surrounding environmental influences is started, the relevant personnel is notified by the integrated telephone alarm, and the anti-theft performance of security anti-theft door type products is improved further.

Description

technical field [0001] It belongs to the field of anti-theft technology. Background technique [0002] Home is the harbor of happiness, and the anti-theft security door is the security to ensure the happiness of the family. [0003] The combination of the anti-theft safety door and the alarm is a very classic anti-theft device, which makes up for the passive protection of the anti-theft safety door. It is very necessary to generate a warning at the beginning of the incident, to avoid the consequences with a high probability. The 2nd, in modern society, the situation of no one at home happens from time to time, and an incident has taken place at this moment, how to let family members know, this is a big loophole on a security.

Problems solved by technology

[0003] The combination of the anti-theft safety door and the alarm is a very classic anti-theft device, which makes up for the passive protection of the anti-theft safety door. It is very necessary to generate a warning at the beginning, to generate a warning at the beginning of the event, and to avoid the consequences with a high probability.

The second is that in modern society, it happens from time to time that there is no one at home. When an incident occurs at this time, how to let the family know is a big loophole in the security.

The third is to make people know the family affairs from outside, it is necessary to use remote control technology, represented by radio remote control, but the remote control is greatly affected by the weather and the surrounding environment, and more and more remote control products have formed In addition to the source of interference, how to make the signal transmission accurate in these harsh factors is also a big problem
