Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
Example 1:
fig. 1 is a schematic structural view of a fire extinguisher actuating device according to the present invention.
The device is provided with a first super capacitor 3-1, a second super capacitor 3-2, a first charging circuit 2-1, a second charging circuit 2-2, a temperature sensor 4, a charging logic circuit 5, a starting logic circuit 7 and a fire extinguisher starting circuit 6. The first super capacitor 3-1 is a first independent starting power supply, and the second super capacitor 3-2 is a second independent starting power supply.
The first charging circuit 2-1 is electrically connected with an external power supply 1 and a first super capacitor 3-1;
the second charging circuit 2-2 is electrically connected with an external power supply 1 and a second super capacitor 3-2;
the first super capacitor 3-1 is electrically connected with the temperature sensor 4, the starting logic circuit 7 and the charging logic circuit 5 to provide working electric energy;
the second super capacitor 3-2 is electrically connected with a fire extinguisher starting circuit 6;
the charging logic circuit 5 is electrically connected with the second charging circuit 2-2 and the fire extinguisher starting circuit 6;
the starting logic circuit 7 is also electrically connected with the temperature sensor 4 and the fire extinguisher starting circuit 6;
the fire extinguisher starting circuit 6 realizes the starting of the fire extinguisher by electrifying the fire extinguisher starting resistor 6-1;
the starting logic circuit 7 is also electrically connected with a fire extinguisher starting feedback circuit 7-1, so that whether the fire extinguisher is normally started or not can be known.
The first super capacitor 3-1 is responsible for powering the temperature sensor 4 and the start-up logic 7. The second super capacitor 3-2 is responsible for the power supply for the start of the fire extinguisher.
The first charging circuit 2-1 is responsible for charging the first supercapacitor 3-1 in the case of an external power supply. The second charging circuit 2-2 is responsible for charging the second super capacitor 3-2 under the condition of external power supply, and is controlled by the charging logic circuit 5 to determine whether to execute the charging action.
The logic truth table of the charge logic circuit 5 is shown in fig. 3.
The fire extinguisher starting circuit 6 is responsible for releasing the electric quantity of the second super capacitor 3-2 to the fire extinguisher starting resistor 6-1, and the fire extinguisher starting circuit 6 is controlled by the starting logic circuit 7 and outputs a signal to the charging logic circuit 5.
The logic truth table of the fire extinguisher activation logic circuit 7 is shown in figure 2.
Under the condition that the first super capacitor 3-1 is powered, the temperature sensor 4 and the starting logic circuit 7 work continuously with micro power consumption.
The temperature sensor 4 is used for sensing the ambient temperature, the temperature information is used as a judgment condition for 'starting' of the fire extinguisher, the fire extinguisher starting feedback circuit 7-1 is used for providing a signal for 'normal starting' of the fire extinguisher and is used as a judgment condition for 'stopping' of the fire extinguisher starting circuit 6. When the starting logic circuit 7 receives a 'normal starting' signal provided by the fire extinguisher starting feedback circuit 7-1, the fire extinguisher is determined to be normally started, the starting logic circuit 7 closes the fire extinguisher starting circuit 6, namely, the power supply to the fire extinguisher starting resistor 6-1 is stopped, and the electric energy is saved.
The charging logic circuit 5 ensures that the capacitor is in a full state and the stored electric energy is sufficient to start the fire extinguisher.
If the second super capacitor 3-2 is in a full-charge state when the fire extinguisher is started, the electric quantity of the second super capacitor 3-2 is only used for supplying power to the fire extinguisher starting circuit 6.
If the fire extinguisher is started, the second super capacitor 3-2 is in a power-down state, the electric quantity of the external power supply 1 is used through the second charging circuit 2-2, and the fire extinguisher can be started.
Example 2:
as shown in fig. 4, only one supercapacitor 3 is used to supply power to the temperature sensor 4, the fire extinguisher starting circuit 6 and the starting logic circuit 7.
Under the condition of power supply of the super capacitor 3, the temperature sensor 4 and the starting logic circuit 7 continuously work in micro power consumption.
The temperature sensor 4 is used for sensing the ambient temperature, the temperature is used as a judgment condition for 'starting' of the fire extinguisher, and the fire extinguisher starting feedback circuit 7-1 is used for providing a 'normal starting' signal and is used as a judgment condition for 'stopping' of the fire extinguisher starting circuit 6. When the starting logic circuit 7 receives a 'fire extinguisher normal starting' signal provided by fire extinguisher starting feedback 7-1, judges that the fire extinguisher is normally started, and closes the starting circuit, namely stops supplying power to the fire extinguisher starting resistor 6-1, thereby saving electric energy.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
