Emergency message transmission method and electronic device implementing the method

1. An electronic device for transmitting an emergency message, comprising:

a storage unit for storing a reference voltage value;

an output unit for outputting information;

a smoke assessing unit for capturing air composition around the electronic device and assessing whether the air composition has changed;

a current detecting unit for detecting an electrical current of the smoke assessing unit when the smoke assessing unit assesses that the air composition has changed;

a converting unit for amplifying the electrical current and converting the amplified current to a converted voltage value, wherein the converting unit further comprises an amplifier and a resistor, the amplifier is configured for amplifying the electrical current, and the resistor is configured for generating a voltage drop for the amplified current, thereby obtaining the converted voltage value;

a power management unit for comparing the converted voltage value with the reference voltage value from the storage unit; and

a processing unit for judging whether the converted voltage value reaches the reference voltage value, controlling the output unit to output a signal including an emergency message when the converted voltage value reaches the reference voltage value.

2. The electronic device as recited in claim 1 , wherein the smoke assessing unit is an ionization type smoke detector.

3. The electronic device as recited in claim 1 , wherein the output unit is a speaker, and is configured for generating a warning alarm when the converted voltage value reaches the reference voltage value.

4. The electronic device as recited in claim 1 , wherein the output unit is a communication unit, and is configured for sending a wireless signal including the emergency message to another electronic device when the converted voltage value reaches the reference voltage value.
