The protective cover 110b is coupled to one side end of the housing 110a, that the multifunctional portable fire extinguisher 200 is held therein, so as to protect the multifunctional portable fire extinguisher 200 from the outside.
In the inside portion of the housing 110a, a first sensor unit 120, a first short range wireless communication unit 130, a first control unit 140, and a voice output unit 150 are formed. The protective cover 110b includes a light unit 160, a first display unit 170, a first emergency button unit 180, and a lock adjustment unit 190.
Here, the first sensor unit 120 serves to detect the temperature, gas, smoke, and power failure and generate a first detection data. At this time, the first sensor unit 120 decides that it is a dangerous to exceed the set point of the temperature, gas, smoke, and power failure and then, generate a first danger data.
Here, the first short range wireless communication unit 130 performs a short range wireless communication with the multifunctional portable fire extinguisher.
Here, the voice output unit 150 outputs a warning call and a request voice signal on a danger level in terms of the temperature, gas, smoke, and power failure detected by the first sensor unit 120 to the outside.
Here, the first control unit 140 serves to control the first sensor unit 120, the first short range wireless communication unit 130, the first display unit 170, and the voice output unit 150.
More concretely, the first control unit 140 serves to transfer the first detection data detected by the first sensor unit 120 to the multifunctional portable fire extinguisher 200 through the first short range wireless communication unit 130.
Also, the first control unit 140 serves to output the first danger data judged by the first detection data detected by the first sensor unit 120 to the first display unit 170 of the protective cover 110b by danger level stages based on criteria stored in advance.
Moreover, the first control unit 140 serves to control the voice output unit 150 in such a manner that the warning call on the danger level in terms of the first detection data detected by the first sensor unit 120 and the request voice signal stored in advance are outputted to the outside through the voice output unit 150.
For example, the voice output unit 150 repeatedly outputs at least any of the warning call and the request voice signal stored in advance such as “wailing  ̃ ̃ ̃my home is 00 street. This is an emergency. Help me.” for a period of time.
Here, the light unit 160 includes a plurality of LEDs formed along the protective cover so as to identify the position of the multifunctional portable fire extinguisher case at night. In this case, it is preferred that the intensity of illumination thereof is more than 6 Lux. Also, the color of the LEDs is variable.
