Since the power unit 10 should be able to operate even in a state where the supply of external power is interrupted in an emergency such as a fire, it is preferable that the power unit 10 is configured as an engine that receives energy while burning the stored fossil fuel.

On the other hand, the power unit 10 requires a separate power source for the start (起動), which is supplied by the charging unit 50 to be described below. In addition, the power source 10 may be activated by the external power source of the building connected to the power unit 10 separately from the charging unit 50.

The pump 20 is connected to the power unit 10. The pump 20 is to compress the digestive water to move along the digestive tract of the building inner wall, it is composed of a general pump (20). At this time, the power unit 10 and the pump 20 may be integrally provided in one frame as shown in FIG.

The control unit 30 is connected to the fire detection sensor installed in the building, when the fire occurrence is detected by the fire detection sensor to operate the power unit 10 and the pump 20 connected to it can be sprayed extinguishing water through the sprinkler. Make sure

At this time, the control unit 30 is connected to the measuring sensor (S) to be described below. That is, the controller 30 determines the state of the charging unit 50 measured by the measuring sensor S, and if there is an abnormality, activates the abnormal state signal of the charging unit 50 and at the same time the temporary state of the charging unit 50. It serves to temporarily operate the power unit 10 to start charging.

More precisely, the controller 30 arbitrarily operates the power unit 10 when there is an abnormality such as the voltage or current of the output power transmitted from the condenser 60 becomes less than or equal to a predetermined level. By acting as a kind of generator to control the charging unit 50 can be charged.

The operation unit 40 is a kind of input device that allows a user to operate the control unit 30 and may be configured in various forms such as a touch panel, a button, a switch, and a control state by having a display connected to the control unit 30. Can be represented externally.

The charging unit 50 is connected to the control unit 30. The charging unit 50 is for supplying power to the power unit 10, and when the fire is generated after charging the usual power to the power unit 10 under the control of the control unit 30 Will be delivered.

That is, the charging unit 50 serves to supply power for the start of the power unit 10, even if the external power is cut off in a situation such as a fire, the power is already charged regardless of the external power It is supplied to the unit 10.

As shown in FIG. 3, the charging unit 50 includes at least one capacitor 53, 55, a distribution circuit 51, and a transmission circuit 55. The capacitors 53 and 55 are actually charging portions, and receive charging power from the light collecting unit 60 and store them as electrical energy.

In the present embodiment, the capacitors 53 and 55 are preferably composed of electric double-layer capacitors 53 and 55 (hereinafter, referred to as 'high capacity capacitors').

The high-capacitance capacitor is a capacitor using charge accumulated in an electric double layer generated between a solid electrode and an electrolyte, and has a relatively superior characteristic in terms of power density that provides instantaneous force but lower energy density than a chemical battery. There is an advantageous effect on the starting of the power unit 10.

In addition, the high-capacity capacitor is capable of repeatedly charging hundreds of thousands of times, and thus has a semi-permanent life, which is very advantageous in terms of maintenance compared to chemical electricity. Of course, the capacitors 53 and 55 are not necessarily limited to high capacity capacitors.

As shown in FIG. 2, the capacitors 53 and 55 are composed of two or more. That is, the capacitors 53 and 55 are composed of a first capacitor 53 and a second capacitor 55, and when an abnormality occurs in any one of the two capacitors 53 and 55, the control of the controller 30 is performed. By the operation of the remaining one capacitor (53, 55) it is possible to transfer power to the power unit (10).

Distribution capacitors 51 are connected to the capacitors 53 and 55. The distribution circuit 51 adjusts the charging power allocated to each of the capacitors 53 and 55 so that the distribution of the output power delivered from the condenser 60 may be uniformly provided to the two capacitors 53 and 55. Do it.

Meanwhile, the transmission circuit 55 is connected to the capacitors 53 and 55. The transmission circuit 55 is a portion for transmitting the power charged in the capacitors 53 and 55 to the power unit 10 so that the output power of the capacitors 53 and 55 can be maintained at a constant value. In the present embodiment, the output power is 14V, but this can be changed through the operation of the transmission circuit 55.

The condenser 60 is connected to the charging unit 50. The light collecting part 60 is a part for supplying electrical energy to the charging part 50 and includes a solar cell panel. The solar cell panel absorbs solar energy and converts it into electrical energy, which is a kind of physical cell. The solar panel is a module in which a plurality of cells are combined, and each cell may be various examples such as a silicon semiconductor or a compound semiconductor.

That is, the charging unit 50 is installed on the outside of the building, it is to perform the function of changing the solar electricity into electrical energy as usual. As shown in FIG. 1, the condenser 60 may be configured such that its inclination angle may be adjusted according to time in consideration of the altitude of the sun that changes with time.

Although not shown, an auxiliary power generation unit is connected to the power unit 10 to supply power to the power unit 10 through control of the control unit 30 in case of abnormality of the charging unit 50 or the light collecting unit 60. You can also supply.

At this time, the auxiliary power generation unit is made of an engine type using a chemical fuel, a separate charge

Hereinafter, a fire engine pump driving method using a fire engine pump system according to the present invention will be described with reference to the drawings. 4 is a flowchart illustrating a method for driving a fire engine pump using a fire engine pump system according to the present invention.

According to this, the condenser 60 normally performs the function of condensing solar energy into electrical energy.

The generated electrical energy is selectively supplied to the charging unit 50, which is controlled by the controller 30.

That is, it is first determined whether the internal voltage of the charging unit 50 measured by the measuring sensor S connected to the charging unit 50 is less than or equal to the threshold value (S20).

If the internal voltage of the charging unit 50 is less than or equal to a threshold value, since the charging unit 50 needs to be charged, the controller 30 may charge the electrical energy generated by the light collecting unit 60 to the charging unit 50. (S30)

At this time, the charging unit 50 supplied with the output power of the light collecting unit 60 is uniformly distributed to the capacitors 53 and 55 through the distribution circuit 51 so that charging is performed.

On the contrary, when the internal voltage of the charging unit 50 is greater than the threshold value, since it is sufficiently charged, it is no longer necessary to charge the charging unit 50, and the charged electrical energy may be converted to other uses of other buildings. have.

Through such a loop, the charging unit 50 always maintains a predetermined state of charge, that is, a state capable of supplying starting power to the power unit 10.

On the other hand, when a fire is generated, the fire detection sensor detects this and transmits a signal to the control unit 30, the control unit 30 transmits the output power of the charging unit 50 to the power unit 10 to the power unit 10 To start. This is because the power unit 10 is composed of an engine, and therefore requires an initial starting power separately from the chemical fuel.

Then, the activated power unit 10 is no longer required to supply power to the charging unit 50, and operates while burning the stored fuel. In this way, the power generated by the power unit 10 is transmitted to the pump 20 is the pump 20 is an operation for compressing the digestive water. That is, the pump 20 compresses the extinguishing water so that the extinguishing water is sprayed through the sprinkler along the digestive tract.

As such, since the charging unit 50 is charged using solar energy, even if a fire occurs and the supply of external power is stopped, the charging unit 50 can stably supply power for starting to the power unit 10, and normally Since it is not necessary, power consumption can be prevented.

In addition, since the charging unit 50 is composed of a high-capacity capacitor rather than a chemical cell, the lifespan is long and the concern about environmental pollution is reduced.

On the other hand, the control unit 30 continuously detects and controls the state of the charging unit 50 and the light collecting unit 60. This control flow is well illustrated in a flow chart in FIG. 5.

As shown in the drawing, once condensing and charging is started (S100), the controller 30 receives the output power transmitted from the charging unit 50 (S110) and measures the voltage (S120).

At this time, the control unit 30 is analyzed by measuring whether the voltage of the output power is normal. As a result, if the output power of the charging unit 50 is naturally dropped by the discharge, the charging unit 50 is charged by the light collecting unit 60 through the above-described process.

However, as shown in FIG. 6, if the output power drops rapidly below the threshold within a short time, the power unit 10 may be temporarily operated by determining that the charging unit 50 or the condenser 60 is abnormal.

More precisely, the determination of the normality of the output power of the charging unit 50 determines the discharge current or voltage drop flow of the charging unit 50 output power over time in the normal state and the discharge current or voltage drop flow in the current state. In comparison, it is made by measuring whether a difference above the threshold occurs between the two.

The reason for temporarily operating the power unit 10 as described above is to start the power unit 10 before the output voltage of the charging unit 50 is completely lowered and falls to a level at which the power supply unit 10 cannot supply starting power. In order to prepare for a fire that may occur between the maintenance of the system by placing, and also to charge the charging unit 50 by utilizing the power unit 10 as a kind of generator (S130).

That is, the charging unit 50 is temporarily charged by using the electric energy generated by the power unit 10.

At the same time, the controller 30 activates a signal for notifying the user that the power unit 10 is temporarily driven. At this time, as an activation means, a speaker, a lamp, etc. can be mentioned. (S135)

On the other hand, when the voltage of the output power of the charging unit 50 is less than the threshold value, the controller 30 measures the output voltage of the light collecting unit 60. (S140) This is because the abnormality of the output power is the light collecting unit ( 60) or by the charging unit 50 is for determining.

At this time, if it is determined that the output voltage of the light collecting unit 60 is abnormal, the control unit 30 performs an operation of notifying the user that there is an error in the light collecting unit 60. Specifically, the control unit 30 recognizes the state in which the abnormality occurs in the light collecting unit 60 to the outside through a lamp or a speaker (S150).

If the measurement result shows that the voltage of the output power of the light concentrating unit 60 is normal, the charging unit 50 may be abnormal. Therefore, the controller 30 may indicate that the charging unit 50 is abnormal. (S180)

At the same time, when an abnormality occurs in the charging unit 50, the control unit 30 activates only the capacitors 53 and 55 having no abnormality among the capacitors 53 and 55 of the charging unit 50, and the rest is connected. By blocking, the charging unit 50 is controlled to operate normally.

Knowing the abnormality of each of these components, the user can replace or repair these parts to keep the fire engine pump system intact, which can be prepared in case.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.
