Single MCU-based motion detection, local alarm and supervisory arrangement for alarm system

An alarm system, comprising:

• an alarm control panel (ACP);
• and
• a plurality of devices with single main control unit (MCU) based motion detection, local alarm and supervisory arrangement connecting with said ACP, wherein comprises:
• a sensor component monitoring environment of said alarm system to generate a reference information, wherein said sensor component of said device comprises an energy sensor adapted for defining a detecting area and detecting energy directed therewithin to produce inputted energy signals;
• an output component communicatively connected with said ACP which is adapted to generate warning messages;
• a power supply component providing power for said device wherein further comprises an auxiliary (AUX) power supply provided by said ACP and a backup power supply providing power for said device when said ACP is not available;
• and
• a microcontroller communicatively connected with said sensor component for receiving said reference information therefrom and drive said output component according to said reference information, wherein said microcontroller monitors said ACP and enables said backup power supply when said ACP is not available, wherein said plurality of devices and said ACP form a local warning matrix network (LWMN), wherein when one of said devices detects motion and sends an alarm signal to said ACP, said ACP will send signal to all devices for alarming, wherein each device of said system works independently when said ACP is destroyed, wherein said inputted energy signals from said energy sensor is processed by said microcontroller which comprises a means for converting said inputted energy signals into data samples, wherein a plurality of data samples are constructed to form a predetermined number of constructed sample window of constructed samples in time, wherein a control range is determined for each of said constructed sample windows, and thus by comparing said relationship between said successive constructed sample windows, said microcontroller is capable of determining whether there is an need to send alarm signals to said ACP.

A process for operating a device with single main control unit (MCU) based motion detection, local alarm and supervisory arrangement for alarm system controlled by an alarm control panel (ACP), comprising the steps of:

• (a) defining a detecting area and detecting energy directed within said detecting area to produce inputted energy signals;
• (b) checking an auxiliary (AUX) Power supply of said ACP;
• (c) enabling a backup power supply to provide power;
• (d) generating audio and/or video alarm alerts for a predetermined period of time if said ACP is destroyed;
• and
• (e) generating audio and/or video alarm alerts for a predetermined period of time when a motion is detected;
• wherein the step (b) further comprises steps of:
• (b1) checking said ACP's arm status if said ACP is operational;
• (b2) checking if said device detects any movement;
• (b3) sending a trigger signal to said ACP when said ACP is armed and a movement is detected;
• (b4) checking a siren signal from a siren output of said ACP;
• and
• (b5) generating audio and/or video alarm alerts for a predetermined period of time if a siren signal is received;
• wherein the step (a) further comprises the steps of:
• (a1) converting said inputted energy signals into data samples;
• (a2) constructing said data samples to form a predetermined number of constructed sample window of constructed samples in time, wherein a control range is determined for each of said constructed sample windows;
• and
• (a3) comparing a relationship between successive constructed sample windows of said constructed sample windows.
