Description

Fire pump monitoring and power control system {Fire pump monitoring and power control system}

The present invention relates to a monitoring and power control system for a fire pump, and more specifically, when the contact signal due to pressure drop is not applied to the monitoring control panel (receiver), signals due to malfunction and voltage instability are transmitted to the power control panel. This relates to a monitoring and power control system for a fire pump that prevents the pump from being driven, while checking the status of the selector switch and linking it with a monitoring control panel during automatic/manual control of the power control panel to ensure that the pump does not operate in an emergency.

In general, a fire pump device includes a priming means to depressurize the internal air for initial pumping, a water tank to store the pumped water, a check valve to prevent backflow, and a fire pump to emit water. It consists of

A fire pump uses a pump driven by power generated by an engine. Compared to a normal motor pump, the device configuration is simpler, and high head and large capacity can be obtained, so it is widely used for firefighting purposes to supply firefighting water necessary for fire extinguishing. It is being used.

These fire-fighting engine pumps are powered by batteries so that they can use rechargeable emergency power in preparation for power that may be cut off in the event of a fire. They are installed in the basement of a multi-story building and must pump fire-fighting water to each floor. It is essential to be equipped with a high-output engine pump, and reliability of operation is very important because it must operate accurately in the event of a fire to minimize damage.

However, in the conventional engine pump, the main pump and the engine that drives it are integrated so that the main pump is operated at 100% when a fire occurs, so a pump with a large capacity and an engine with a corresponding capacity are required, and the main pump is operated at 100% capacity. If the pump breaks down, it will no longer function as a fire pump.

In addition, the conventional engine pump is a main water molding method, so the surface of the rotary car is rough, so the efficiency is low by 20 to 30%, so a high-output engine is required, and due to the characteristics of the engine, it can only be installed horizontally, reducing the installation area of the underground machine room. Space utilization is limited as it takes up a lot of space.

In addition, in the case of conventional engine pumps, they are made of gray iron or bronze and are operated only in the event of a fire, so there is a problem of rust occurring if not used for a long period of time. As a result, it is not practical to start due to sticking of the rotor, etc., so it does not play a role in extinguishing fire in the event of a fire. Failure to do so may result in significant property damage.

As a prior art to solve the above problems, Republic of Korea Patent No. 955704 (announced on May 3, 2010, title of invention: storage type fire pump system) consists of a main pump and a spare pump in parallel in one pipe. In the beginning, the main pump operates at 50%, but when usage increases and there is a water shortage, the spare pump operates interlocked at 50%, so the power can be set to be smaller than the engine pump, and even if the main pump breaks down, the spare pump is operated at 50%. Since it can be operated as a pump, it is possible to prepare for fire pump failures, and by reducing the starting torque by using a high-efficiency vertical pump manufactured by press molding and an inverter, the power of the motor used in the pump can be selected at a low level. Since it is installed in a vertical structure, it is possible to maximize space utilization by minimizing the installation area of the underground machine room. In addition, by applying a stainless steel vertical pump, rust in the rotary car is fundamentally prevented, and the controller control It is characterized by the ability to prevent rotor sticking problems by performing automatic test operation of the pump on a regular basis.

However, the above prior art has problems in that it cannot accurately start and stop due to fatigue build-up, and that malfunctions occur due to deformation when on/off operations are repeated. In addition, it is composed of a complex management system that requires regular inspection and operating status to be visually confirmed or set in the field, and the pressure setting method is complicated, which makes actual use inconvenient.

Furthermore, since the above prior art did not have seismic performance in preparation for an earthquake, the main pump and reserve pump for extinguishing a fire did not operate, making it difficult to extinguish the fire.

In addition, as another prior art, Korea Registered Utility Model No. 279421 (announced on June 24, 2002, design name: digital pressure switch with pressure gauge) includes a pressure gauge that can visually check the pressure in the pipe and the starting or stopping pressure of the pump. A dual-use digital pressure switch device is disclosed.

According to this, the digital pressure switch that doubles as a pressure gauge includes a DC power input unit, a power switch for power on/off, a stop pressure adjustment switch for setting the stop pressure, a starting pressure adjustment switch for setting the starting pressure, and a zero point adjustment switch for setting the reference point. It consists of a pressure control unit, a pressure detection unit that also detects the external pressure flowing in from the pressure inlet pipe connected to the pressure pipe, a memory unit, a control unit, and a signal output unit, and displays the stop pressure set value, starting pressure set value, and detected pressure respectively. It includes a display section consisting of a stop pressure display section, a starting pressure display section, and a pressure display section, and displays the external pressure, starting pressure, and stop pressure in digital numbers or letters, which saves costs by eliminating the need for a pressure gauge. The pressure can be adjusted conveniently and accurately, the external pressure is converted into a digital signal and stored, and the external pressure and stop pressure input by the manager are compared/analyzed with the external pressure and an on/off control signal is output through the signal output unit. It allows precise control of the start and stop of external devices.

Fire pumps installed in the above fire-fighting objects can be operated on-site from a power control panel installed near the pump room, and water-based fire-fighting equipment pumps such as sprinkler equipment and indoor fire hydrants installed in fire-fighting objects of a certain size or larger can be operated remotely by a monitoring control panel. It is operated by monitoring the driving and driving conditions.

As described above, the method of remotely monitoring operation with a monitoring control panel consists of a part of the operation circuit of the power control panel as a monitoring control panel, operates by forming a contact point inside the monitoring control panel, and uses the power output when the pump is in operation. Monitoring the operating status of the pump.

With such a monitoring control panel, there is a problem in that it cannot be confirmed if an abnormality occurs inside the power control panel, such as a trip or manual switching of the selector switch.

Even if a fire occurs and the pressure switch is activated and a power input signal is sent from the monitoring control panel to the power control panel, the fire pump does not start if the switch on the power control panel is in the manual position or automatic recovery is not made. This cause is caused by the monitoring control panel. Since it is unknown, there was a problem that it took a lot of time to start the pump.

In addition, there was a problem that fire response was delayed because abnormal signals (trip occurrence or manual switching of the selector switch) could not be confirmed in the power control panel.

Data information is stored and managed so that it can be managed.

The PCB controller 420 displays a switch that controls whether the engine pump is running, a display to identify the battery and fuel amount, and always detects the remaining battery and fuel amount, and provides an alarm when the battery and fuel amount are insufficient as a result of the detection. It is possible to output to the outside through at least one signal information of an alarm sound signal or a lighting signal through a siren, etc.

Here, the engine pump refers to a spare pump for use when power is not supplied in the event of a fire or emergency.

In addition, the PCB controller 420 detects the degree of heat generation in proportion to the amount of current applied to the pump 100, thereby controlling whether the overcurrent relay, which determines whether the pump 100 is overloaded, operates.

Furthermore, the PCB controller 420 provides QR code information or address code information to facilitate individual control of at least one pump 100 among the main pump 110, spare pump 120, charge pump 130, and engine pump.

The operation of the fire pump monitoring and power control system according to the present invention configured as described above will be described.

There are two cases in which the main pump 110 is started except for test start.

When a fire breaks out in a building and the pressure in the fire extinguishing water supply pipe decreases, switching is performed by a change in pressure in the hydraulic switch device 200, and a switching signal is applied to the monitoring control panel 300, and the FPC controller is sent from the monitoring control panel 300. In the first case, a switching signal is applied to (420), and a signal is received from the FPC controller (420) to start the main pump (110), which starts the pump at a set pressure and sprays fire extinguishing water to extinguish the fire.

The second case is a case where a signal is applied to the FPC controller 420 due to a malfunction of the monitoring control panel 300, so that the main pump 110 is started to spray fire extinguishing water. In the second case above, extreme water damage occurs.

In order to solve the above problems, even when a fire occurs and the main pump 110 is started or when the main pump 110 is started due to malfunction, multiple signals are applied to the FPC controller 420. , Only when both of these signals are satisfied, power is supplied from the FPC controller 420 to the main pump 110 to enable startup.

In other words, a signal is applied from the hydraulic switch 200 to the monitoring control panel 300, and a signal is applied from the monitoring control panel 300 to the FPC 400, and at the same time, the signal is applied from the hydraulic switch 200 to the FPC 400. By applying a low signal, the main pump 110 is started only when both signals are received from the FPC controller 420, thereby preventing the main pump 110 from starting due to malfunction and preventing water damage.

And when a fire occurs and a signal is applied to the FPC (400) from the hydraulic switch device (200) and the monitoring control panel (300), the FPC (400) applies an electrical signal to the main pump (110) to start it. do.

At this time, the main pump 110 is activated by an electrical signal applied to the main pump 110, and the water pressure switch 200 checks whether the pressure of the main discharge pipe 111 has reached the set pressure, and the water pressure If the pressure checked by the switch 200 is determined to be below the set pressure, it is determined that the main pump 110 does not start and a signal is applied to the microcomputer 421 of the FPC controller 420.

If the microcomputer 421 determines that the main pump 110 is not started, the microcomputer 421 of the FPC controller 420 can apply an electrical signal to the inverter 424 to start the spare pump 120. Skip operation is performed by applying an electrical signal by changing the frequency. In the skip operation, not only the spare pump 120 is started, but the spare pump 120 and the filling pump 130 can be started simultaneously.

In addition, the operation signal of the switch 411 is applied to the monitoring control panel 300, and the stop switch is turned on by an actuator (not shown) installed on one side of the switch by the signal applied to the monitoring control panel 300, The LED lamp located at the top of the corresponding switch 411 lights up.

As described above, when the switch 411 installed on the FPC enclosure 410 is operated, the actuator (not shown) installed on the monitoring control panel 300 operates and the same switch is placed in the activated state, so that even a single worker can check the starting state of the pump. can be checked.

In addition, when the pump 100 is started, the pressure of the fire extinguishing water discharged through the main discharge pipe 111 is checked by the hydraulic pressure switch 200 and applied to the FPC controller, so that it can be confirmed whether the fire extinguishing water is discharged at the set pressure. .

Additionally, when inspecting the pump 100, it can be determined that skip operation is performed with the power source connected to the main pump 110 removed. That is, when the start switch among the switches 411 installed in the FPC enclosure 410 is turned on, a signal is applied to the monitoring control panel 300 and at the same time an electrical signal is applied to the main pump 110.

The actuator is driven by a signal applied to the monitoring control panel 300 to change the starting switch 411 to the on state. In addition, while an electrical signal is applied to the main pump 110, the pressure is checked in the hydraulic opening and closing device 200, and if the pressure is determined to be below the set pressure, a signal is applied to the FPC controller 420 to operate the spare pump 120. ) is applied to drive the electric signal.

When the electrical signal applied to the microcomputer 421 of the FPC controller 420 is again applied to the inverter 424, the inverter 424 converts the frequency and applies an electrical signal to drive the preliminary pump. At this time, if the pressure of the fire extinguishing water discharged through the spare pump 120 is determined by the hydraulic switch device 200 to be below the set pressure, an electrical signal to increase the pressure is applied from the hydraulic switch device 200 to the FPC controller 420. do.

The microcomputer 421 of the FPC controller 420 applies an electrical signal to the inverter 424, and the inverter 424 converts the frequency and applies an electrical signal to drive the charging pump 130. The electric signal from the inverter activates the pressure pump to discharge fire-fighting water appropriate to the set pressure.

As described above, in the present invention, when the contact signal due to pressure drop is not applied to the monitoring control panel 300, the signal due to malfunction and voltage instability is transmitted to the FPC controller 420 to drive the pump 100. In order to prevent this, the signal from the hydraulic switch device 200 is applied to the monitoring control panel 300 and the FPC controller 420, respectively. And the FPC controller 420 operates the pump 100 only when there is a signal applied from the hydraulic switch 200 together with the signal from the monitoring control panel 300, thereby controlling the monitoring control panel 300 and the hydraulic switch 200. ), the pump 100 is started only when each signal applied from ) is confirmed, thereby preventing water damage due to malfunction, voltage instability, etc.

In addition, the present invention allows the status of the switch 411 of the FPC 400 to be checked through an LED lamp (not shown) in the monitoring control panel 300 in the same way as the on/off switch, so that the status of the switch 411 of the FPC 400 can be checked through an LED lamp (not shown). The status can be checked through the monitoring and control panel (300).

In addition, the present invention enables skip operation by controlling the driving of the pump 100 and the RPM of the blower through the pump 100 and blower control panel according to frequency by the inverter 424 of the FPC 400. .

In addition, in the present invention, the FPC (400) controls excessive supply of blowing air generated by the blower of the smoke control equipment and enables efficient operation to maintain the pressure set in the smoke control area installed on each floor.

In addition, the FPC 400 of the present invention allows control of signals applied from a mobile phone, so that when the main pump fails, the spare pump or the remaining pressure pump is automatically operated to facilitate fire suppression.
