Abstract

The invention provides an emergency call alarm system and method, and can be conveniently matched with an existing mobile communication terminal, thereby enhancing and expanding distress signals, and realizing active and timely call alarms. The abovementioned system includes a plurality of alarm devices, each alarm device includes a processor, an antenna, a band-pass filter, a wireless signal receiving unit, a wireless signal sending unit, a storage, a data exchange interface and a signal sending switch. The abovementioned method includes the following steps: a system is initialized; an active alarm device sends alarm information outwards; the alarm information is sent to a set object through a corresponding mobile communication terminal; a standby alarm device in an alarm system receives the alarm information, automatically controls a wireless signal sending unit to be turned on through a corresponding processor, and forwards the received alarm information; and at least three alarm devices which receive the alarm information in the alarm system form an ad hoc network, and position the active alarm device through an alarm signal, thereby completing an alarm.

Description
