Description

The present invention relates to a control device, a fire pump device, an external display, and a method for stopping a fire pump device.

Buildings are equipped with fire pump equipment to discharge water in the event of a fire. This fire pump equipment is required to operate reliably in the event of a fire, but since it is normally stopped, it is necessary to check its operation during maintenance. (See Patent Document 1.)

JP 2016-142184 A

The equipment is operated periodically so that it can be started reliably in the event of a fire. Here, examples of the operation methods of the fire pump equipment include "machine-side start", in which the pump is started/stopped by an inspector operating the start/stop button on the operation panel on the fire pump equipment side (hereinafter referred to as the machine side), and "remote start", in which the pump is started/stopped by a signal from a remote location away from the fire pump equipment. Furthermore, "remote start" can be "input of a fire occurrence signal" or "manual input operation". In this way, the fire pump equipment has multiple operation methods as an operation method in the event of a fire. In addition to these operation methods in the event of a fire, the operation methods also include a test operation method for maintenance. It is necessary to periodically check whether the pump is operating correctly in all of these multiple operation methods that the fire pump equipment has. This is because possible abnormalities in the fire pump equipment include malfunctions of the operation button and breaks in the signal line that outputs the start signal, and any abnormality may cause the pump to be unable to start in the event of a fire. However, when an inspector checks that the pump is running and attempts to stop the operation on the operation panel of the fire pump equipment on site, if a start command signal such as "remote start" is still input, the operation from the operation panel will not be accepted, resulting in problems such as the worker pressing the stop button multiple times, which could damage the button or lead to the mistaken belief that the stop button is broken.

The present invention has been made in consideration of the above problems, and aims to provide a control device, a fire pump device, an external display, and a method for stopping a fire pump device that are capable of identifying the method for stopping a pump during operation.

The control device according to the first aspect of the present invention is a control device for a fire pump apparatus including a pump and a drive for driving the pump, and includes a control unit for controlling the fire pump apparatus, a start button and a stop button for starting/stopping the pump, and the control unit includes an input unit capable of inputting signals from the start button and the stop button, and a remote start signal for operating the pump remotely, and a first circuit unit for driving the pump, and the first circuit unit is configured as a self-holding circuit that outputs a first contact signal that is set by inputting at least one of the signals from the start button and the remote start signal and is reset by inputting a signal from the stop button, and when the first contact signal is set, a remote start display signal that is turned ON or OFF depending on whether or not the remote start signal is input is displayed on an operation panel that can exchange signals with the control unit.

With this configuration, the operation panel displays whether or not a signal to operate the pump remotely has been input. This allows workers on-site to know that a remote start signal is being input, and they can identify how to stop an operating pump, such as turning off the input of the remote start signal and then performing the stop operation. This prevents problems such as workers repeatedly pressing the stop button, which can cause damage, or mistaking the stop button for a malfunction.

The control device according to the second aspect of the present invention is the control device according to the first aspect, in which the control unit further has an electronic circuit unit equipped with a calculation unit, the control unit and the driving panel have communication units capable of communicating information processed by their respective calculation units, the control unit transmits a remote start display signal to the driving panel via communication, and the driving panel displays the received remote start display signal.

With this configuration, the remote start indication signal, which is a signal used in the first circuit unit, is input to the electronic circuit unit, and the electronic circuit unit transmits the remote start indication signal to the operation panel via communication, simplifying the wiring without adding a dedicated signal line.

The control device according to the third aspect of the present invention is the control device according to the first or second aspect, and the control unit further has an electronic circuit unit equipped with a calculation unit, a second circuit unit that outputs a second contact signal that is turned ON or OFF by an operation command output from the electronic circuit unit to which a test operation command for the pump is input, and a logical OR circuit that conducts or cuts off the power supply supplied to the drive machine by the logical OR of the first contact signal and the second contact signal.

With this configuration, during test operation, the pump operation and stopping are controlled by the electronic circuit unit, making it possible to perform more complex control than the first circuit unit, such as stopping the pump in the event of an abnormality. Also, even if the electronic circuit unit goes out of control in the event of a fire, the first circuit unit can continue to operate the pump.

The control device according to the fourth aspect of the present invention is a control device according to any one of the first to third aspects, and has an operation display means for displaying the operation status of the pump, a test operation display means for displaying the test operation of the pump, and the remote start signal display means for displaying the remote start display signal, arranged side by side on an operation panel on which the stop button is provided, so that an operator can simultaneously check the operation of the pump, the test operation of the pump, and the remote start status.

This configuration allows the operator to simultaneously check the pump's operation, test operation, and remote start status.

The control device according to the fifth aspect of the present invention is a control device according to any one of the first to fourth aspects, and has a plurality of methods for starting/stopping the pump, and the operation panel has an operation method setting means that can prioritize, from among the plurality of methods, machine-side activation that starts/stops the pump by operating the operation panel.

With this configuration, the pump can be set to start/stop on the machine side by operating the operation panel.

The control device according to the sixth aspect of the present invention is the control device according to the fifth aspect, and includes a timer that starts when the operation method setting means switches to prioritize the machine-side activation, and cancels the priority of the start/stop command by the machine-side activation after a predetermined time has elapsed.

With this configuration, after switching to machine-side startup, the priority of machine-side startup can be automatically cancelled after a certain period of time has elapsed, which can prevent situations in which the machine cannot be started/stopped by other methods (e.g., remotely) due to forgetting to revert the priority to machine-side startup.

This configuration allows the operator to check that the pump is operating via remote start at the machine, improving convenience.

The control device according to the eighth aspect of the present invention is a control device according to any one of the first to seventh aspects, and is provided with a display unit that displays a method for stopping the test operation if the pump is in test operation.

This configuration allows workers to understand how to stop a test run.

With this configuration, the external display shows how to stop the pump, allowing the operator to more specifically understand how to stop the pump.

In the method of operating a fire pump apparatus according to the twelfth aspect of the present invention, when stopping the fire pump apparatus, if the apparatus is in fire operation and the remote start signal is ON, a method for stopping the apparatus during remote operation is executed, if the apparatus is in fire operation and the remote start signal is OFF, a method for stopping the apparatus during on-site operation is executed, and if the apparatus is in test operation, a method for stopping the apparatus during test operation is executed.

With this configuration, the fire pump device can be stopped in each case.

According to one aspect of the present invention, when a pump is being operated with a signal input to operate the pump remotely, the input status of the signal is displayed on the operation panel. This allows an on-site worker to know that a remote start signal is being input, and the worker can identify how to stop the pump while it is running. This prevents problems such as a worker repeatedly pressing the stop button on the machine without realizing that a remote start signal is being input, which could damage the machine, or mistaking the stop button for a malfunction.

Each embodiment will be described below with reference to the drawings. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to make it easier for those skilled in the art to understand.

Figure 1 shows the overall configuration of the fire pump system of this embodiment. In this example, the fire pump system is composed of a water supply unit 12, which is configured by mounting a fire pump 10 and its associated peripheral equipment on a common base 11 to form a unit, a water discharge system 14 that operates independently on three floors, an underground water tank 16 and an auxiliary elevated water tank 17 as water sources, and piping connecting these. In the event of a fire, the water supply unit 12 can supply water from the water source to the water discharge system 14 to extinguish the fire.

2 to 4, the water supply unit 12 includes a fire pump (also simply called a pump) 10, a driving motor 18, which is an example of a driving machine, and a control panel 20. The water supply unit 12 of this embodiment includes a priming tank 22, a heat prevention relief device 24, and piping connecting these, a flexible pipe (flexible pipe joint), a check valve 70, a gate valve 71, a test flow measurement device 68, a pressure detector 72 for starting the pump, a suction pipe cover, a foot valve for the suction pipe, and a starting pressure tank 74 (described later). A water level sensor 75 for measuring the water level of the priming tank 22 is also provided, and a temperature sensor 81 for measuring the temperature of the driving motor 18 is also provided. The temperature sensor 81 may detect the temperature of the fire pump 10 instead of the driving motor 18. The pressure detector 72, the temperature sensor 81, the water level sensor 75, the current detector CT1 and the current detector CT2 (described later), etc. are collectively referred to as sensors. The fire pump 10 is operated as a direct-coupled type in which the pump body and the driving motor 18 that drives it are directly connected on a common base 11, or as an integrated direct-acting type. A power line 25 is connected to the control panel 20, and a normal power source 27 and an emergency power source 28 are connected to this via a power source switching means 26.

Figure 5 is a front view of the control panel. The control panel 20 houses the control unit 40, which is a control board that controls the fire pump 10, the details of which will be described later. The control unit 40 includes an electronic circuit unit 46 composed of electronic components including a CPU (Central Processing Unit) 45 equipped with a memory unit, input/output ports, a calculation unit, etc., and the control panel 20 surface is provided with operation switches, a liquid crystal display, a 7-segment LED or an operation panel 42 (see Figures 5 and 7), switches and buttons for inputting various settings, and a setting device, which are necessary for operating the fire pump 10. The operation panel 42 also includes an electronic circuit unit 126 composed of electronic components including a CPU (Central Processing Unit) equipped with a memory unit, input/output ports, and a calculation unit, and communicates with the control unit 40 to share various information and display various states of the water supply unit 12. The control panel 20 also includes an operation switch 20a that allows an operator to operate the fire pump 10 to start/stop in response to a test operation command.

The various operation switches provided on the control panel 20 may be mechanical contact switches or contactless switches. The operation panel 42 displays letters, numbers and symbols in segments on an LCD display, displays status in a segment display, or displays in a dot matrix. An LED display can be used to display similarly to an LCD display. In the case of an LED display, the display may be achieved by turning indicator lights on and off around the written characters, or the indicator lights may be lit by switching the color. The operation panel 42 is equipped with an indicator lamp unit 150 that indicates its ON/OFF state, and the indicator lamp unit 150 includes a power supply indicator 151 that indicates power continuity, an operation indicator 152 that indicates the operation state of the fire pump 10, a stop indicator 153 that indicates the stop state of the fire pump 10, a motor overcurrent indicator 154 that indicates an overcurrent in the motor of the fire pump 10, a priming tank reduced water indicator 155 that indicates a reduced water level in the priming tank, a test operation indicator 121, which will be described in detail later, and a remote start signal indicator 122. The indicator lamp unit 150 is configured, for example, with an LED or the like that lights up or goes off depending on the ON or OFF state of each state.

As shown in FIG. 5, the water supply unit 12 may be connected wirelessly or by wire to an external display 300 capable of displaying its status. The external display 300 may be a general-purpose communication terminal such as a smartphone, personal computer, or tablet, or may be a dedicated communication terminal. The external display 300 functions as the external display 300, for example, by executing an application capable of communicating with the control unit 40 and/or the operation panel 42. The external display 300 may have the same functions as the operation panel 42. In that case, the external display 300 is an example of the operation panel 42, as described below.

Each floor of the building is provided with a water discharge system 14 including a closed sprinkler head 50 as a water discharge means (see FIG. 1). This water discharge system 14 includes a main pipe 52 extending from the fire pump 10 along the vertical direction of the building, floor pipes 54 branching off from the main pipe 52 on each floor, area pipes 56 branching off from the floor pipes 54 in a predetermined area of each floor and extending along the ceiling, and sprinkler heads 50 installed at a predetermined interval along the area pipes 56. The end of the main pipe 52 is connected to an auxiliary elevated water tank 17, which is installed on the roof, for example, via an opening/closing valve 58 and a check valve 60. An auxiliary sprinkler valve 62 is installed at a predetermined location of each floor pipe 54 as necessary. An end test valve 64 and a pressure indicator 66 are attached to the end of each area pipe 56.

The suction side of the fire pump 10 is connected to an underground water tank 16, which is a water source, via a suction pipe 10a. A priming tank 22 is provided above the fire pump 10 to prime the internal cavity of the fire pump 10. A constant water level is constantly maintained in the priming tank 22 by the fire pump 10 itself or by an external water supply means, and a test device 68 is provided to verify that the performance of the fire pump 10 is still at its original capacity.

A check valve 70 is provided at the base end of the main pipe 52 (the side that connects to the water supply unit 12), and a pressure detector 72 is provided between the check valve 70 and the downstream on-off valve 71. Furthermore, a startup pipe 76 that connects to a startup pressure tank 74 joins the check valve 70. The startup pressure tank 74 is managed to maintain a certain gas pressure (a pressure that allows water to be discharged from the sprinkler head 50 on the top floor), and a certain pressure is always applied to the water in each pipe from the main pipe 52 onwards. An automatic alarm 78 is provided on each floor pipe 54. The output of the automatic alarm 78 is sent via a receiver 80 to the control panel 20, and the output of the pressure detector 72 is sent directly to the control panel 20.

The operation of the fire pump equipment configured as above will be explained. When a fire breaks out in a specific area of a building, the sprinkler head 50 in that area detects the fire, and for example, the fuse metal sealing the tip melts and opens, and water in the piping pressurized by the startup pressure tank 74 is sprayed to the area. This water spray causes the internal pressure of the startup pressure tank 74 to suddenly drop, and the control unit 40 detects the drop signal and starts the fire pump 10. Specifically, the pressure switch provided in the startup pressure tank 74 acts as a fire detector, and the control unit 40 starts the fire pump 10 when the drop signal is input to the control unit 40. At the same time, the automatic alarm 78 detects the flow of water in each floor piping 54 on the floor where the sprinkler head 50 was activated, and if the signal is input to the control unit 40, it is determined on which floor the fire has broken out, and the control unit 40 can control the fire pump device so that water can be sprayed on that floor.

<Control unit and operation panel functions>
Fig. 6 is a schematic functional block diagram of the fire pump apparatus according to this embodiment. As shown in Fig. 6, the fire pump apparatus S includes a fire pump 10, a driving motor 18 for driving the fire pump 10, a control unit 40, and an operation panel 42 capable of exchanging signals with the control unit 40. The driving motor 18 is connected to, for example, a three-phase commercial power source CP by a power line. One embodiment of the fire pump apparatus S is the above-mentioned water supply unit 12. In addition, instead of the commercial power source CP of this embodiment, a normal power source 27 or an emergency power source 28 connected via a power source switching means 26 may be used.

The fire pump device S further includes a current detector CT1 that detects the current in the U-phase wiring from the commercial power source CP to the drive motor 18, and a current detector CT2 that detects the current in the W-phase wiring from the commercial power source CP to the drive motor 18. The current detectors CT1 and CT2 are connected to the control unit 40. The fire pump device S further includes a relay circuit RC, and when the relay circuit RC is set, the wiring between the commercial power source CP and the drive motor 18 is made conductive, and when the relay circuit RC is reset, the wiring between the commercial power source CP and the drive motor 18 is cut off.

The control unit 40 includes a start/stop determination means 111, an abnormality determination means 112, a fire operation start/stop means 113 connected to the start/stop determination means 111, a test operation start/stop means 114 connected to the start/stop determination means 111 and the abnormality determination means 112, and a terminal T1 connected to a remote management device (not shown). The control unit 40 further includes a pump drive means 115 connected to the fire operation start/stop means 113 and to the test operation start/stop means 114. The output of the pump drive means 115 is connected to a relay circuit RC, and controls the drive and stop of the fire pump 10 by energizing or cutting off the power supplied to the drive motor 18 via the relay circuit RC. The pump drive means 115 is, for example, a relay circuit that performs a logical OR between the output signal of the fire operation start/stop means 113 and the output signal of the test operation start/stop means 114.

The start/stop determination means 111 is configured with a circuit including an input/output port provided in the control unit 40. The start/stop determination means 111 may be realized by control software executed by the CPU 45 or the calculation unit of the CPU 45, at least some of its functions. The abnormality determination means 112 and the test operation start/stop means 114 are realized by control software executed by the CPU 45 or the calculation unit of the CPU 45, at least some of their functions. The test operation start/stop means 114 further includes a relay circuit (second circuit unit, not shown in FIG. 6, see FIG. 7), which will be described in detail later. The fire operation start/stop means 113 is configured with a relay circuit (first circuit unit), which will be described in detail later. In this way, since the fire operation start/stop means 113 is configured with a relay circuit (first circuit unit) without going through the CPU 45, even if the CPU 45 runs out of control under conditions of temperature rise during a fire or unstable power supply, the pump will not be stopped erroneously. This allows the fire operation start/stop means 113 to continue fire operation without erroneous shutdown. In addition, the test operation start/stop means 114 has some functions configured with control software executed by the CPU 45, so it has the effect of providing high design freedom for operation control, such as stopping the system before a breakdown occurs in the event of an abnormality, as control during test operation.

The start/stop determination means 111 outputs operation information indicating whether it is a test operation or an operation during a fire to the operation panel 42 via communication. Here, the start/stop determination means 111 has terminals T1, T2, and an operation method determination means 130 connected to a fire detector. A remote fire/test start/stop command input to terminal T1 from a fire detector or a remote management device is input to the operation method determination means 130. As a result, when the operation method determination means 130 determines that the operation is a remote start, if the state of the fire detector or the signal of terminal T1 is a remote "fire" start/stop command, it outputs a fire start/stop command to the fire operation start/stop means 113, and if the state of the signal of terminal T1 is a remote "test" start/stop command, it outputs a test start/stop command to the test operation start/stop means 114. As a result, the fire pump 10 can be started or stopped remotely for fire or test. In addition, the operation method determination means 130 regards a state in which "fire pump 10 is operating" and "a fire start signal has been input from a remote location" as the ON state of the "remote start signal," and a state in which "fire pump 10 is stopped" or "no fire start signal has been input from a remote location" as the OFF state of the "remote start signal," and outputs the ON or OFF state to the remote start signal display means 122 of the operation panel 42 via communication.

On the other hand, when the operation switch 20a receives an operation from the operator to perform a test run, a test run command is input from the operation switch 20a to the operation method determination means 130 via terminal T2. When a test run command is input, the operation method determination means 130 determines that the test run command is to be started, and outputs a test start command to the test run start/stop means 114.

The start/stop judgment means 111 has a switch 111a that can select whether or not to perform a test run. When "test run" is selected by the switch 111a, a test start command is output to the test run start/stop means 114 according to the above-mentioned conditions. When "test run not" is selected by the switch 111a, operation by test run is not possible. In other words, regardless of the above-mentioned conditions, a test start command is not output to the test run start/stop means 114. This makes it possible to prevent a third party other than an inspector with specialized knowledge from carrying out a test run. In this embodiment, the switch 111a that can select whether or not to perform a test run is provided in the start/stop judgment means 111. In one embodiment, the switch 111a may be provided in the test run start/stop means 114 or may be provided as a function of the operation panel 42. In addition, the test run start/stop means 114 may make a judgment not to perform a test run.

The abnormality determination means 112 is connected to the current detector CT1 via terminal CN18 and to the current detector CT2 via terminal CN19. The abnormality determination means 112 determines whether an overload (start failure) has occurred using the current value detected by the current detector CT1 and/or the current value detected by the current detector CT2. Furthermore, the abnormality determination means 112 determines whether other abnormalities (low water in the priming tank, abnormal drop in discharge pressure, etc.) have occurred. If the abnormality determination means 112 determines that an abnormality has occurred, it outputs a signal indicating the abnormality to the test operation start/stop means 114.

Here, a specific example of the process of the abnormality determination means 112 will be described. The abnormality determination means 112 may determine that an abnormality has occurred when, for example, the current value detected by the current detector CT1 and/or the current detector CT2 corresponds to an abnormal increase in the current value (for example, when the current value is equal to or greater than the current threshold), when an abnormality in the current value is detected by an electronic thermal function using a pre-stored inverse time limit characteristic, when a leakage breaker (not shown) detects a leakage, or when one or more detection values detected by various sensors (for example, the pressure detector 72, the temperature sensor 81, and/or the water level sensor 75) correspond to a temperature abnormality, an abnormal pressure drop, and/or a drop in the water level of the priming tank 22. The temperature abnormality is, for example, when the temperature of the fire pump 10 or the driving motor 18 is equal to or greater than the temperature threshold. The abnormal pressure drop may be when the discharge pressure is equal to or less than the pressure threshold, when the discharge pressure is equal to or less than the pressure threshold and the current value is equal to or less than the current threshold, or when a small amount of water is detected. The drop in the water level of the priming tank 22 may be when the water level is equal to or less than the water level threshold.

The fire operation start/stop means 113 (first circuit section) controls the means 113 to output a start signal to the pump drive means 115 when a fire start/stop command is input, and to output a fire pump 10 stop signal when a fire stop command is input. Specifically, when a fire start command is input, the means 113 sets and self-holds the first contact signal output to the pump drive means 115 to set the relay circuit RC, and when a fire stop command is input, the means 113 resets the self-held first contact signal to reset the relay circuit RC. The fire operation start/stop means 113 (first circuit section) is configured as a self-holding circuit that is set by the signal input of the fire start command (at least one of the start button 141 and the input signal to the terminal T1 or the remote start signal which is the input signal of the fire detector) and outputs a signal (first contact signal) that is reset by the signal input of the fire stop command (stop button 142). As a result, in the case of a fire start command, the fire pump 10 is driven, and until a fire stop command is input and the fire pump 10 is stopped, the operation of the fire pump 10 can be continued without being stopped even if an abnormality or power outage occurs. Also, while the remote start signal is being input, the control unit 40 continues to operate the fire pump 10 even if a fire stop command (stop button 142) is input.

Similarly, when a test start/stop command is input, the test operation start/stop means 114 (second circuit section) controls the pump to start operation in the case of a test start command (specifically, for example, output an ON signal (second contact signal) to the pump drive means 115), and controls the pump to stop operation in the case of a test stop command (specifically, for example, interrupt the output of the ON signal output to the pump drive means 115). As a result, the fire pump 10 is driven in the case of a test start command, and the fire pump 10 is stopped in the case of a test stop command. Also, even if a power outage occurs while the fire pump 10 is operating, the CPU 45 is reset when power is restored, so the fire pump 10 returns in a stopped state. This makes it possible to avoid test operations that are not intended by the operator.

When an abnormality (start failure) is input from the abnormality determination means 112, the test operation start/stop means 114 interrupts the operation command and controls the pump to stop operation (specifically, for example, by interrupting output to the pump drive means 115). This allows the fire pump 10 to be stopped when an abnormality occurs.

The operation panel 42 includes a test operation display means 121 , a remote start signal display means 122 , an operation method setting means 123 , a start/stop input means 124 , and a timer 125 .
When the operation information output from the start/stop determination means 111 of the control unit 40 indicates a test operation, the test operation display means 121 displays that the operation is a test operation in a recognizable manner.

The remote start signal display means 122 displays the "remote start signal" output from the operation method determination means 130 in a recognizable manner. Specifically, for example, when a remote start signal is input, the remote start signal display means 122 displays in a recognizable manner that the remote start signal is being input. This allows an operator (e.g., an inspector) to check whether or not a remote start signal is currently being input, so that even if the operator inputs the stop button 142, the control unit 40 can recognize that the operation of the fire pump 10 will continue.

The start/stop input means 124 receives a start or stop operation from the worker (e.g., an inspector) and outputs a start/stop command according to the received operation. Specifically, for example, when the start/stop input means 124 receives a start operation, it outputs a start command, and when the stop operation is received, it outputs a stop command. In other words, the start/stop input means 124 is an example of a start input means and a stop input means.

The operation method setting means 123 can prioritize the machine side start, which starts/stops the fire pump 10 by operating the operation panel 42, among a plurality of methods for starting/stopping the fire pump 10 possessed by the control device 40. In this embodiment, the operation method setting means 123 accepts an operation by an operator (e.g., an inspector) to switch between the machine side start, which starts/stops the fire pump 10 by operating the operation panel 42, and the test start, which starts/stops the pump by a signal input to the terminal T2, and outputs a setting signal corresponding to the accepted operation to the control unit 40.
In response to this, the operation method determination means 130 of the control unit 40 determines a method for starting/stopping the fire pump 10 according to the setting signal output from the operation method setting means 123. When the operation method determination means 130 determines that the fire pump 10 is to be started on the machine side, the test operation start/stop means 114 starts or stops the pump according to the start/stop command output from the start/stop input means 124.

With this configuration, even if the fire pump 10 is undergoing a test run due to a signal input to terminal T2, if an operator (e.g., an inspector) at the site operates the operation method setting means 123 to switch to local start, the fire pump 10 can be stopped by operating the stop button 142 on the operation panel 42. Then, if the operator (e.g., an inspector) subsequently inputs start via the start/stop input means 124, the pump can be started, so that the pump can be started and stopped at the site even if the remote start signal is set to remain input.

The timer 125 issues a notification a certain time after it has been started. The operation method setting means 123 accepts an operation to switch to machine-side activation, and if machine-side activation is prioritized, starts the timer 125, and if a notification is received from the timer after a certain time has passed, outputs the notification to the operation method determination means 130. With this configuration, the priority of machine-side activation can be automatically released a certain time after switching to machine-side activation, so it is possible to prevent a situation in which it becomes impossible to start/stop the device by other methods (for example, from a distance) because the priority was set and the user forgot to return the setting.

Furthermore, when a setting signal indicating remote start is input, the operation method determination means 130 outputs a "remote start signal" to the remote start signal display means 122. The remote start signal display means 122 displays, in response to the remote start signal output from the operation method determination means 130, a recognizable indication that a remote start signal is being input. This allows the operator to confirm that the pump is operating by remote start on the machine side, improving convenience.

Figure 7 is an example of a schematic front view of the operation panel according to this embodiment. As shown in Figure 7, the operation panel 42 shows an indicator light as an example of the test operation display means 121, which is turned on during the test operation. An indicator light is shown as an example of the remote start signal display means 122, which may be turned on when the remote start signal is being input (ON state) and turned off when the remote start signal is not being input (OFF state), or may be turned on in a first color when the remote start signal is being input (ON state) and turned on in a second color when the remote start signal is not being input (OFF state). Note that, as one embodiment, the test operation display means 121 and the remote start signal display means 122 may not be provided in the operation panel 42, and may be displayed only on the external display 300.

The start/stop input means 124 has, for example, a start button 141 and a stop button 142. In the case of machine-side start, when the start button 141 is pressed, the fire pump 10 starts, and when the stop button 142 is pressed under certain conditions described below, the fire pump 10 stops.

Figure 8 is a schematic diagram of the circuit configuration of the fire pump apparatus according to this embodiment. As shown in Figure 8, the control unit 400, which is an example of the circuit configuration of the control unit 40 whose function has been described in Figure 6, includes an input unit 40a that can input signals from the start button 141, which is a start input means, and the stop button 142, which is a stop input means, as well as a remote start signal for operating the pump remotely, and a first circuit unit 104 that outputs a first contact signal for driving the fire pump 10. Here, the first circuit unit 104 is an example of the fire operation start/stop means 113. Also, the operation panel 420 is an example of the circuit configuration of the operation panel 42 whose function has been described in Figure 6.

The first circuit section 104 is configured as a self-holding circuit that outputs a first contact signal that is set by at least one of the start button 141 input from the operation panel 420 and the remote start signal input from the terminal T1, and is reset by the stop button 142 signal input from the operation panel 420. When the first contact signal output from the first circuit section 104 is set, a remote start display signal that is ON or OFF depending on whether or not the remote start signal is input is displayed on the remote start signal display means 122 of the operation panel 420. As a result, if the remote start signal is input, the stop button 142 cannot be used as a means for stopping the fire pump 10, but by displaying the remote start signal display means 122 in this way, the operator can understand that the remote start is in progress and the stop button 142 cannot be used.

The control unit 400 further includes an electronic circuit unit 46, a sensor input unit 102, a communication unit 103, a first circuit unit 104, a second circuit unit 105, and a logical OR circuit 106. The electronic circuit unit 46 has a CPU 45 including a calculation unit. The communication unit 103 is a communication driver that converts signals transmitted and received by the CPU 45 into, for example, RS485, RS232C, etc., and information processed by the calculation unit of the CPU 45 can be transmitted and received by communication with the communication unit 127 of the operation panel 420.

The sensor input unit 102 performs signal processing such as A/D conversion of the input detection value of the sensor 101, and outputs the signal-processed detection value to the abnormality determination unit 453. Here, the sensor 101 is, for example, a current detector, a thermometer, a pressure switch, or a priming tank water level.
When the remote start signal is input, the electronic circuit unit 46 transmits a remote start display signal via communication from the communication unit 103 to the operation panel 420. The operation panel 420 then displays the received remote start display signal. Here, the CPU 45 of the electronic circuit unit 46 functions as a remote start signal determination unit 451, an automatic inspection processing unit 452, an abnormality determination unit 453, and a test operation command determination unit 454.

When a remote activation signal is input, the remote activation signal determination unit 451 determines that remote activation has occurred.
The automatic inspection processing unit 452 executes an automatic inspection process in response to an automatic inspection signal input from the automatic inspection option board 200. In the automatic inspection process, for example, the fire pump 10 is started/stopped at a preset cycle. When the automatic inspection signal indicates a test operation start, the automatic inspection processing unit 452 outputs a test operation start signal to the test operation command determination unit 454. On the other hand, when the automatic inspection signal indicates a test operation stop, the automatic inspection processing unit 452 outputs a test operation stop signal to the test operation command determination unit 454.

The abnormality determination unit 453 determines whether or not an abnormality exists according to the detection value input from the sensor input unit 102. If the abnormality determination unit 453 determines that an abnormality exists, it outputs a stop signal to the test operation operation command determination unit 454. The abnormality determination means 112 described above is, for example, configured with the abnormality determination unit 453. The test operation operation command determination unit 454 outputs an operation command to the second circuit unit 105 according to the input automatic inspection signal. In addition, when the test operation operation command determination unit 454 receives a stop signal from the abnormality determination unit 453, it sets the operation command to the OFF state. As an example, part of the function of the start/stop determination means 111 described above is configured with the test operation operation command determination unit 454.

The first circuit section 104 is for driving the pump. The first circuit section is configured as a self-holding circuit that outputs a first contact signal that is set by at least one of the start button 141 and the remote start signal input, and is reset by the stop button signal input. Then, when the first contact signal is set, the CPU 45 of the control section 400 causes the operation panel 420 to display a remote start display signal that is ON or OFF depending on whether or not the remote start signal is input. Specifically, for example, when the remote start signal is input, the control section 400 transmits the remote start display signal to the operation panel 420 by communication, and the operation panel 420 displays the received remote start display signal. As a result, the remote start display signal is transmitted to the operation panel 420 by communication, so that the wiring can be simplified. That is, for example, when a remote start signal is input from the outside, the control unit 400 inputs the remote start indication signal input from the outside to the first circuit unit 104 (arrow Y1 in FIG. 8) and the remote start signal judgment unit 451 of the CPU 46 (arrow Y2 in FIG. 8). The remote start indication signal input to the first circuit unit 104 is output to the logical sum circuit 100 as a first contact signal to operate the fire pump 10. On the other hand, the remote start indication signal input to the CPU 46 is transmitted to the operation panel 420 by communication via the communication unit 103, and the operation panel 420 displays the received remote start indication signal. In this way, since the remote start indication signal is transmitted from the control unit 400 to the operation panel 420 by communication, the wiring can be simplified compared to the case where a dedicated wiring is provided.

The second circuit unit 105 is an example of the test operation start/stop means 114. The second circuit unit 105 outputs a second contact signal that is turned ON or OFF by an operation command output from the electronic circuit unit 46.
The logical sum circuit 106, which is an example of a pump driving means 115, sets or resets a relay RC that connects or cuts off a power source (CP) supplied to the driving machine by the logical sum of the first contact signal and the second contact signal.

The operation panel 420 has an electronic circuit section 126 that is composed of electronic components including a CPU 128 that has a memory section, an input/output port, and a calculation section. The operation panel 420 also has a setting means 120 that includes an operation method setting means 123. The operation panel 420 also has a start button 141, which is an example of a start input means, and a stop input means 142, which is an example of a stop input button 142.

The operation panel 420 also has a communication unit 127 capable of communicating with the communication unit 103 of the control unit 400. This communication unit 127 is a communication driver for transmitting and receiving communication data to the communication unit 103 of the control unit 400. This communication data includes information such as various settings, operation/stop status, various abnormalities, pump operation, pump stop, test operation in progress, and remote start signal.
The operation panel 420 also includes a display unit 129. This display unit 129 includes a liquid crystal display, a 7-segment LED, an indicator lamp, and the like, which are controlled by the electronic circuit unit 126, and displays whether the power is on or off, the operating state, the stopped state, the presence or absence of various abnormalities (e.g., the presence or absence of an overcurrent in the motor, low water in the priming tank, etc.), whether a test run is in progress, and the presence or absence of a remote start signal.

Next, an example of a method for stopping the pump of the fire pump apparatus according to this embodiment will be described with reference to FIG. 9. As described above, the method for stopping the fire pump 10 during operation differs depending on the signal input to the control unit 400. FIG. 9 is a flow chart showing an example of a method for stopping the fire pump 10 according to this embodiment.

(Step S10) First, the operator determines whether the system is in fire operation. In other words, the operator determines whether the system is in fire operation or test operation.

(Step S20) If it is determined in step S10 that the unit is in fire operation, the operator determines whether the remote start signal is on or off. In other words, the operator determines whether the remote start signal input from outside is on or off.

(Step S30) In step S20, if the remote start signal on the operation panel 420 is lit (i.e., if the remote start signal is ON), the method for stopping the operating fire pump 10 is the remote operation stopping method 1 described below.

(Step S40) In step S20, if the remote start signal on the operation panel 420 is not lit (i.e., if the remote start signal is OFF), the method for stopping the operating fire pump 10 is the stopping method during on-site operation of stopping method 2 described below.

(Step S50) If it is determined in step S10 that the fire pump 10 is not in fire operation (i.e., in test operation), the method for stopping the operating fire pump 10 is the stopping method during test operation, which is stopping method 3 described below.
In this way, when stopping the fire pump 10, if the fire operation is in progress and the remote start signal is ON, the operator executes the shutdown method during remote operation, if the fire operation is in progress and the remote start signal is OFF, the operator executes the shutdown method during local operation, and if the test operation is in progress, the operator executes the shutdown method during test operation.

(Stop method 1: How to stop when the remote start indication signal is ON)
The following steps are taken to stop the operating fire pump 10. In other words, if the remote start signal display means 122 displays the ON state of the remote start display signal (i.e., the remote start signal display means 122 is lit), the operator can recognize that the following steps are required to stop the operating fire pump 10.
Step 1: The remote start indication signal input to terminal T1 is turned OFF.
Step 2: Press the stop button 142.
In other words, in this case, the condition for stopping the fire pump 10 is that the remote start indication signal that is input before the stop button 142 is pressed must be turned OFF.

(Stop method 2: How to stop when the remote start indication signal is OFF)
The operating fire pump 10 is stopped in the following steps. In other words, if the remote start signal display means 122 displays the OFF state of the remote start display signal (i.e., the remote start signal display means 122 is turned off), the operator can recognize that the operating fire pump 10 can be stopped in the following steps.
Step 1: Press the stop button 142.
In other words, in this case, the condition for stopping the fire pump 10 is simply to press the stop button 142.

(Stopping method 3: Stopping during test operation)
The operating fire pump 10 is stopped in the following steps. In other words, if the test operation display means 121 displays that the test operation is in progress (i.e., the test operation display means 121 is lit), the operator can recognize that the operating fire pump 10 can be stopped in the following steps.
Step 1: Set the operation switch 20a to the stop position.
In other words, step 1 turns off the test operation start signal input to terminal T1.

In this way, the method of stopping the operating fire pump 10 differs depending on whether the remote start indication signal is present (ON or OFF). In this embodiment, the worker can identify the method of stopping the operating fire pump 10 by checking the remote start signal display means 122. This prevents the worker from repeatedly pressing the stop button 142 in an attempt to stop the fire pump 10 without realizing that the remote start indication signal is ON, which can cause damage to the button.

The control unit 400 also has a CPU 45, which is an electronic circuit unit equipped with a calculation unit, and the control unit 400 and the operation panel 420 each have a communication unit capable of communicating information processed by their respective calculation units, and the remote start display signal is input to the CPU 45 equipped in the control unit 400, which then transmits the input remote start display signal to the operation panel 420 via communication, and the operation panel 420 displays the received remote start display signal. This makes it possible to omit wiring of signal lines. Also, if the CPU 45 is insulated from the fire operation start/stop means 113 (first circuit unit 104), then even if the CPU 45 goes out of control in a fire, it will not affect the fire operation start/stop means 113.

The control unit 400 also has a test operation start/stop means 114 (second circuit unit 105) that outputs a second contact signal that is turned ON or OFF by an operation command output from the CPU 45, and a logical OR circuit 106 of the first contact signal and the second contact signal, which turns on or off the power supply CP supplied to the drive unit 18. As a result, in the event of a fire, the fire pump 10 can be operated regardless of test operation until the stop button 142 is input.

Furthermore, a signal indicating whether or not a test run is being performed is input to the CPU 45 provided in the control unit 400, and the CPU 45 transmits the input signal via communication to the operation panel 420, and the operation panel 420 displays the received signal on the test run display means 121.

Here, in the fire pump apparatus S, if the fire pump 10 does not stop even when the stop button 142 is input, the following factors may be considered.
(1) Abnormality in the operation panel 420 and/or control unit 400, such as a failure of the stop button 142 or a broken signal line.
(2) A state in which the input of a remote start indication signal from an external device continues.
(3) A state in which a test operation command is input via the operation switch 20a.
In the case of (1), the operator must take measures such as replacing the control unit 400 or the operation panel 420 since the device is abnormal, but in the cases of (2) and (3), the device is operating normally and no special measures are required. Therefore, the fire extinguisher S is required to have a mechanism that allows the operator to easily determine whether the device is in the case of (1) or (2) or (3).

In particular, when the "remote start indication signal" described in (2) is a signal output from a fire detector installed in the fire extinguishing equipment, it is assumed that the specifications of the signal output will vary depending on the specifications of the fire detector. Therefore, in the conventional technology in which the remote start indication signal is not displayed, if the fire pump 10 does not stop after the operation to stop the operation panel 420, the worker had to go to check the output status of the fire detector installed in a distant place (for example, a floor different from the floor on which the fire pump 10 is installed). In contrast, in this embodiment, by checking the display of the remote start signal display means 122 of the operation panel 420, it is possible to determine whether (1) the operation panel 420 (stop button 142) is abnormal or (2) the state is maintained by inputting the remote start indication signal. This is because if there is an abnormality in the stop button 142, the remote start signal display means 122 of the operation panel 420 is turned off. In other words, if the operation display means 152 is on, the test operation display means 121 is off, and the remote start signal display means 122 is off, and the worker operates the stop button 142 but the fire pump 10 does not stop, it can be determined that (1) there is an abnormality in the operation panel 420 (stop button 142).

In this embodiment, the operation display means 152, the test operation display means 121, and the remote start signal display means 122, which are dedicated display means (LEDs in this embodiment) showing each state, are arranged on the operation panel 420 on which the stop button 142 is provided so that the operator can simultaneously check the operation, test operation, and remote start states of the fire pump 10. (See FIG. 7) This allows the operator to more smoothly perform the work flow from operating the stop button 142 to making the above-mentioned judgment. In this embodiment, the operation display means 132, the test operation display means 121, and the remote start signal display means 122, which are dedicated display means (LEDs in this embodiment) showing each state, are arranged on the operation panel 420 at positions where they can be simultaneously seen. In one embodiment, instead of or in addition to the test operation display means 121 and the remote start signal display means 122, the test operation and the remote start signal may be selectively displayed on a liquid crystal display and a 7-segment LED provided on the operation panel 420.

Figure 10 is a diagram showing the display contents of an external display capable of displaying the status of the fire pump apparatus. The above-mentioned stop methods 1 to 3 may be displayed on an external display 300 capable of displaying the status of the fire pump apparatus S. Although FIG. 10 describes the stop methods in words, graphics or photographs imitating the display 42 or terminals T1 and T2 may also be used. (A), (B), and (C) of FIG. 10 may show the above-mentioned stop methods 1, 2, and 3, respectively. In addition, (A), (B), and (C) of FIG. 10 show displays such as "operating at a distance," "operating on the machine side," and "operating for testing" together with stop methods 1, 2, and 3. This allows the operator to simultaneously check the operating status of the fire pump 10, which has the effect of improving workability. In this embodiment, "Remote operation", "Local operation", and "Test operation" are displayed as text information, but in one embodiment, they may be displayed as graphics imitating the operation display means 152, remote start signal display means 122, and test operation display means 121 shown in the operation panel 42 in FIG. 7. By unifying the display with the operation panel 42, the operator can recognize the stopping method without misunderstanding.

The control unit 40, 400 can be connected by wireless or wired communication to an external display 300 capable of displaying pump stop methods 1 to 3 selected according to the presence or absence of a remote start signal input and/or information on whether or not a test run is in progress while the fire pump 10 is in operation. The control unit 40, 400 then transmits to the external display 300 at least one of the remote start signal status, whether or not a test run is in progress, and the pump stop method. Based on the received data, the external display 300 selects one of screens (A) to (C) for the corresponding stop method from pre-stored screens or creates a new screen and displays it.

In this embodiment, the control unit 40, 400 having a calculation unit, the operation panel 42, 420, and/or the external display 300 can select one of the stop methods 1 to 3 based on the presence or absence of a remote start signal input, or/and information on whether a test operation is in progress. In other words, the control unit 40, 400 having a calculation unit, the operation panel 42, 420, and/or the external display 300 is provided with a control program that executes the flowchart shown in FIG. 9, and the control program is executed constantly or periodically (for example, every few msec) during the operation of the fire pump 10. In this way, the fire pump device S can clearly show different stop methods in various states, thereby improving the convenience of the operator. In one embodiment, any of the corresponding stop methods 1 to 3 may be displayed on the operation panel 42, 420.

As described above, the fire pump apparatus S according to this embodiment is a fire pump apparatus including the control units 40, 400 and the operation panel 42 capable of exchanging signals with the control units 40, 400. The operation panel 42 has an operation method setting means 123 that receives a switching operation and outputs a setting signal corresponding to the received operation so as to give priority to the machine side start-up that starts/stops the pump by operating the operation panel, and a start/stop input means 124 that receives a start or stop operation from the user and outputs a start/stop command corresponding to the received operation.
The control unit 40, 400 has an operation method determination means 130 which determines whether machine-side start or remote start is to be performed in accordance with the setting signal output from the operation method setting means 123, and a test operation start/stop means 114 which starts or stops the pump in accordance with the start/stop command output from the start/stop input means 124 if machine-side start is determined.

With this configuration, even if remote start is set, if a user (e.g., an inspector) at the site operates the operation method setting means 123 to switch to machine-side start, machine-side start can be prioritized. Then, if the user (e.g., an inspector) subsequently inputs stop via the start/stop input means 124, the pump that is operating using another start method can be stopped, so that the pump can be stopped on the machine side even if it is operating using another start method.

As mentioned above, the present invention is not limited to the above-mentioned embodiment as it is, and in the implementation stage, the components can be modified and embodied without departing from the gist of the invention. Furthermore, various inventions can be formed by appropriately combining the multiple components disclosed in the above-mentioned embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, components from different embodiments may be appropriately combined.
