Vehicle wireless alarm anti-theft equipment

Abstract

The invention relates to an automobile wireless theft-proof alarm, comprising a terminal device provided with a casing and a handheld device provided with a casing, wherein, the terminal device comprises an SCM (single chip micyoco), a crystal oscillation circuit, a reset circuit, a short-distance wireless communication module, a relay, an acousto-optic alarm and a power supply. The SCM is connected through a special interface with the crystal oscillation circuit, the reset circuit, the short-distance wireless communication module, the relay, an indicator and the power supply. The handheld device comprises an SCM, a crystal oscillation circuit, a switch, an external interrupt circuit, a short-distance wireless communication module, an acousto-optic alarm and a power supply, and the SCM is connected through a special interface with the crystal oscillation circuit, the short-distance wireless communication module, the acousto-optic alarm and the power supply, and the external interrupt circuit is connected through the switch with the SCM. The invention internally adopts the low-cost, low-power and high-stability SCM controlling technique and can realize a timely detection to the abnormal states of automobiles through an external sensor, and the alarming signal can be transmitted through a wireless communication chip to the handheld device so as to lead the owner of the automobile to deal with the abnormality actively and in time.
