Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an automatic inspection system for fire extinguishing equipment, which is equipped with a relay pump equipment for pressurizing pressurized fire extinguishing water from the fire extinguishing pump equipment and sending it to an upper floor. Regarding

[Prior Art] Conventionally, in a high-rise building, etc., there is a limit to the height at which a single fire pump can supply fire extinguishing water under pressure, so a relay pump should be installed on the floor on the way and the relay pump should be used again. Fire extinguishing equipment will be installed to send water to the upper floors after pressurization.

In the fire extinguishing equipment equipped with such a relay pump, the pumps are started sequentially from the pump on the lower floor to the pump on the upper floor. This is because if the upper pump is started without starting the pump on the lower floor, the water supply main pipe on the lower floor, which is the suction side, will be evacuated, and the piping may be damaged.

On the other hand, with regard to stopping the pump, on the contrary, the pumps on the upper floor are sequentially stopped toward the pumps on the lower floor to prevent damage to the pipes due to vacuuming.

By the way, even with fire extinguishing equipment using such relay pumps, automatic inspection is necessary to maintain the equipment performance at all times, and the site side responds to periodic inspection commands from the center's automatic inspection management board. An automatic inspection relay board is provided to perform an automatic inspection to determine whether or not a predetermined performance can be obtained by operating the pump.

[Problems to be Solved by the Invention] However, there has been no example of automatic inspection of fire-extinguishing equipment using a relay pump, and the inspection method manually performed at present is different depending on the inspector. It is desired to establish automatic inspection of fire extinguishing equipment equipped with.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide an automatic inspection device for fire extinguishing equipment that can more appropriately perform automatic inspection of fire extinguishing equipment provided with a relay pump.

[Means for Solving the Problems] First, the present invention relates to a main pump facility that pressurizes fire extinguishing water from a water tank to send water to a water supply main that has been started up in a vertical direction of a building, and water supply from the main pump facility. Whether or not the specified performance can be obtained from the measurement data obtained by the deadline operation of the pump, which is equipped with a relay pump facility that pressurizes the fire extinguishing water that has been boosted and sends it to the water supply main that has been launched to the upper floor. It is intended for automatic inspection equipment of fire extinguishing equipment that automatically performs a pump operation test to judge or a pump performance test to judge whether or not a prescribed performance can be obtained from measured data by actually sending pressurized fire extinguishing water.

According to claim 1 of the present invention for such an automatic inspection device for fire extinguishing equipment, when the inspection command is received, the main pump equipment at the bottom of the building is started to obtain a predetermined pump performance. In the event of an emergency, automatic inspection control means will be provided to sequentially activate and inspect the relay pump equipment on the upper floor.

Further, according to claim 2 of the present invention, when an inspection command for the relay pump equipment on a specific floor is received, another pump equipment located below the relay pump equipment to be inspected is replaced with the main pump equipment. After sequentially starting from and checking the performance simply,
Inspection control means for starting the designated relay pump facility and performing an original inspection is provided.

[Operation] According to the automatic inspection device of the present invention having such a configuration, when the automatic inspection command is received, the pump is started from the bottom pump equipment, and the predetermined performance is obtained. Occasionally, inspection control is performed to start and inspect the next pump equipment located one above the other, and the lower pump may be stopped or the upper pump may be started without the prescribed performance being obtained. Since there is no such equipment, it is possible to properly and automatically inspect each pump facility in cooperation with other pump facilities located below.

In addition, regarding the inspection that specifies the relay pump equipment on a specific floor, other pumps located under the pump targeted for inspection are started sequentially from the bottom, but in this case, the pump performance targets all measurement data. Instead, by performing a simple inspection that determines the limited items, the time delay until the start of inspection of the designated pump can be minimized, and a quick pump inspection of a specific floor can be performed.

[Embodiment] FIG. 1 is an explanatory diagram showing a basic configuration of the present invention.

Various data of 10-1 are measured so that it can be judged whether or not a predetermined pump performance can be obtained.

An alarm valve 42 equipped with a water flow detection device 40 is installed in the branch pipe 20 for the water supply main pipe 18-1, and the sprinkler head is provided.
When a water flow is generated in the branch pipe 20 by the operation of 22, the detection output of the water flow detection device 40 is obtained, and a fire alarm is issued to the receiver side and at the same time, the main pump equipment 10-1 is started by the pump control panel 28-1. I have to. An end test device 44 is provided at the end of the branch pipe 20. The terminal test device 44 is provided with a motorized valve 46 and an orifice 48.
A flow rate corresponding to the operation of one sprinkler head regulated by 48 is made to flow through the branch pipe 20, and the water flow detection device 40 of the alarm valve 42 is artificially operated so that a test involving pump operation can be performed.

Next, the relay pump facility 10-2 provided on the main pump facility 10-1 will be described. A pump control panel 28-2 and a relay panel 24-2 are also provided for the relay pump facility 10-2. Further, a test pipe 34-2 is provided, and the test pipe 34-2 is provided with an electric valve 36-2 and a flow meter 38-2.

To be done. Further, an auxiliary pressurizing pump facility 50-2 for maintaining the internal pressure of the water supply main pipe 18-1 adjacent to the relay pump facility 10-2 at a predetermined pressure is installed. That is,
The auxiliary pressurizing pump facility 50-2 is provided with a fire pump 60 (motor is omitted), a preliminary water tank 52 and a pressure tank 54. The water supply main 18-1 is connected to the pressure tank 54 and a pressure switch 56 is used. The pressure inside the pipe is monitored. When the pressure switch 56 detects a decrease in the internal pressure of the water supply main 18-1, the pump 60 is activated to restore the internal pressure of the water supply main 18-1 to a predetermined pressure via the pressure tank 54.

The discharge side of the fire pump 16 of the relay pump equipment 10-2 is connected to the auxiliary water tank 52 via the electric valve 58, and the electric water valve 58 is opened while the relay pump equipment 10-2 is operating to open the auxiliary water tank. Water can be supplied to 52, which can prevent the rise in water temperature.

The same applies to the next relay pump facility 10-3 provided on the relay pump facility 10-2.

Then, an auxiliary pressurizing pump equipment 50-4 is installed at the end of the last water supply main 18-3, that is, on the roof side, and this auxiliary pressurizing pump equipment 50-4 is the auxiliary pressurizing pump equipment 50-2, It is exactly the same except that there is no route for receiving water from the relay pump facility side via the electric valve 58 as in 50-3.

The pump operation inspection in the automatic inspection for the fire extinguishing equipment shown in FIG. 2, that is, the inspection for judging the performance by shutting down the pump, for example, the main pump equipment 10-1 when performing the inspection of all equipment. Operate in the deadline state, and if the prescribed performance is obtained, then operate the relay pump equipment 10-2 in the deadline state, and if the prescribed performance is further obtained, relay pump equipment 10-3
Run with deadline.

On the other hand, in the pump performance inspection, that is, in the inspection to judge the performance by actually flowing water for extinguishing fire, for example, for the inspection command of all equipment, first start the main pump equipment 10-1 and then test pipes. The motor-operated valve 36-1 provided in 34-1 is opened to flow a predetermined flow rate determined by the flow meter 38-1, and it is determined from the measurement data obtained in this state whether predetermined performance can be obtained.
If the predetermined pump performance is obtained in the main pump equipment 10-1, the motor operated valve 36-1 is closed while continuing the pump operation,

-3 Main pump equipment located on the lower side for inspection-10-
1 and relay pump equipment 10-2 must be started in sequence. In this case, even if the pump equipment that is not the inspection target is simply started, if there is an abnormality in the pump equipment, correct performance cannot be obtained by inspecting the designated relay pump equipment 10-3. Therefore, it is necessary to inspect the main pump equipment 10-1 and the relay pump equipment 10-2 which are not inspected in exactly the same manner. However, if a specific pump equipment is specified and all other pump equipment therebelow are checked in the same manner, it takes too much time to check the specified pump equipment.

Therefore, in the present invention, when the inspection of a specific pump facility is designated, the pump facility located on the floor below the pump facility is simply inspected after the pump is activated to activate the next pump facility. .

Specifically, for example, if a pump performance inspection is instructed to the relay pump equipment 10-3, for the main pump equipment 10-1 and the relay pump equipment 10-2 located therebelow,
Only the inspection by the pump shutoff operation will be performed, and if the specified performance is obtained as a result, a simple inspection will be performed to shift to the operation of the pump equipment on the upper floor. This simple inspection can be further simplified. For example, when the prescribed pump discharge pressure and pump coupling gauge pressure are obtained by starting the pump, it is determined that the predetermined performance has been obtained, and the next pump equipment is started. Of course, the items for the simple inspection are the pump control panel voltage, the pump control panel current, the motor speed, etc. as the measurement data for the inspection. Check it.

FIG. 3 is a system configuration diagram of the automatic inspection apparatus of the present invention for the fire extinguishing equipment of FIG.

In FIG. 3, relay boards 24-1, 24-2, ... Are provided in the main pump facility 10-1 and the relay pump facilities 10-2 ,.

Explaining the relay board 24-1 as a representative, the main pump equipment 10-
A local repeater 62 is provided for each terminal testing device 44 of the branch pipe 20 provided for each floor, which is connected to the water supply main 18-1 from 1. The local repeater 62 is provided on the repeater board 24-1. It is connected to the signal line, and a specific local relay board 62 is called by polling from the relay board 24-1 and the terminal test equipment is called.
By opening the motor-operated valve 46 provided at 44, the fire extinguishing water is made to flow through the branch pipe 20 in a pseudo manner, so that the pump operation test by the pseudo fire can be performed in the same manner as when the sprinkler is operating. A pump control board 28-1 is connected to the relay board 24-1. Further, a plurality of sensors 64 are connected, and these sensors 64 include, for example, the tachometer 35 shown in FIG. 2, a pressure gauge for detecting pump discharge pressure, a compound gauge for detecting pump suction pressure, and pump control. A voltmeter, an ammeter, etc. provided on the panel 28-1.

The connection configuration for such a relay board 24-1 is the relay board 24-
The same applies to 2.

The relay boards 24-1, 24-2, ... Are commonly connected to the management relay board 25 via a signal line, and perform bidirectional data transmission with the management relay board 25 by the polling method. A central management board 26 installed in a center or the like is connected to the management relay board 25 by a signal line.

Next, the pump operation inspection test according to the present invention will be described with reference to the flowchart of FIG. This pump operation inspection test is based on the case where all pump facilities are targeted.

First, when the central control board 26 gives an inspection command specifying the pump operation inspection mode to the management relay board 25, the pump operation inspection processing shown in FIG. 4 is started. This pump operation inspection start can be specified in four modes M1 to M4. That is, in the manual inspection command, the equipment is selected by the light pen as shown in the mode M1, and then the inspection item is selected by the light pen in the mode M2. On the other hand, for automatic inspection, automatic equipment selection is performed in mode M3, and automatic inspection start is turned on by a command from the host device in mode M4.

When the inspection is started manually or automatically, first, in step S1 (hereinafter, "step" is omitted), the pump to be tested is designated. That is, the pump number X is designated. However, if all pumps are to be inspected, the pump number on the top floor should be specified.

Next, in S2, the inspection items and time are printed, and the next
At S3, the first measurement pump setting n = 1 is performed. Specifically, when n = 1, the main pump equipment 10-1 in FIG. 2 is designated as the measurement pump.

Next, in S4, the static data of the pump for which n = 1 is measured and printed. This static data measurement printout includes pump insulation resistance, current, voltage, pump compound pressure, pump discharge pressure,
It is the number of rotations of the electric motor, and pressure air tank pressure, fire extinguishing agent storage tank pressure, sprinkler main pipe pressure, etc. are measured as necessary in parentheses.

Then, in S5, if the insulation resistance of the electric motor is equal to or higher than the specified value, the main pump equipment 10-1 is assumed to be normal, and in S6, it is determined whether the measured pump setting n reaches the pump designation number X, If not reached, n = n + 1, that is, after setting the next relay pump equipment 10-2 as the measurement pump equipment, the process proceeds to S4, and the static data is similarly measured and printed. If the insulation resistance is not more than the specified value in S5, it is determined that there is an insulation failure in the motor and the process proceeds to S20 and the inspection is stopped. Further, when it is determined that the static data measured in S4 is not the specified value, the process may proceed to S20 and the inspection may be stopped.

When the check regarding the static data of all the pump equipment is completed, the process proceeds to S7, and the starting pump setting m = 1 is performed. At this time, the starting pump designated by m = 1 is the main pump facility 10-1 in FIG. Subsequently, in step S8, the m-th pump for which the starting pump is set, that is, the pump starting control of the main pump equipment 10-1 is performed, and when starting is confirmed in step S9, the process proceeds to step S10.
S4 for data measurement and printing when the pump is shut off
Perform the same items as in.

Then, the process proceeds to S11, and it is checked whether predetermined performance is obtained with respect to the current value and the motor rotation speed, and if the performance conditions are satisfied, the process proceeds to S12. In S11, measurement data other than the current value and the motor rotation speed may be checked to determine whether the performance condition is satisfied. It is checked whether or not the starting pump setting m has reached the pump designation number X, and if not, the starting pump setting m is set to m = m + 1 and the next pump facility, that is, the relay pump facility 10-2 is set as the starting target, Returning to S8, the pump is started in the same manner, and it is determined whether or not the predetermined performance is obtained by measuring the data in the deadline operation state.

Here, assuming that the pump designation number X = 3 is set, when the performance check of the relay pump facility 10-3 by the deadline operation is completed, the process proceeds to S13, and the stop pump setting t
Then, the last designated pump designation number X is set as t = X.

Subsequently, in S4, the pump designated by t = X, that is, the pump stop control of the relay pump equipment 10-3 that has been started last is performed, the stop is confirmed in S15, and the stop pump setting t = in S16.
1, that is, whether or not stop control up to the main pump equipment 10-1 has been performed, and until the main pump equipment 10-1 is stopped, S1
The processing of 4, S15 and S16 is repeated.

Finally, when the stop control of the main pump equipment 10-1 is performed,
To go to S17 and measure the static data after the end of operation,
The measurement pump setting n = 1 is performed in the same way as S3, and the next S1
Similar to the case of S4 at 8, the static data of the pump is measured and printed. At S19, static data of all the pump equipment is measured and printed after the operation is completed, and a series of pump operation is performed. Finish the inspection.

Fig. 4 shows that even if the inspection of all pump equipment is instructed or the inspection of pump equipment on a specific floor is instructed, the pump equipment at the bottom sequentially has a predetermined performance based on the measurement data obtained by the deadline operation. It is determined whether or not is obtained, and when the prescribed performance is obtained, the pump equipment located on the upper floor is sequentially started, but when the inspection of the pump equipment on a specific floor is specified. In addition, a simple inspection may be performed on the pump equipment on the floor below. Specifically, for pump facilities on the lower floor that are not subject to inspection, only the discharge pressure and suction pressure are determined in S11, and therefore in S10, a simple inspection is performed by measuring only the discharge pressure and suction pressure. Can be Further, instead of the discharge pressure and the suction pressure, it is sufficient to determine the electric motor current value or rotation speed in S11, and in this case, measure the control panel current or rotation speed in S10.
For pump equipment not subject to inspection, S4
Also, measurement printing of static data before and after inspection in S18 may be omitted.

5A and 5B are flow charts showing the control processing for pump performance inspection according to the present invention.

First, the processing when a pump performance inspection is designated that specifies pump equipment on a specific floor will be described. Regarding the inspection command designating this specific floor, in this embodiment, the pump equipment on the floor below the designated pump equipment is subjected to the pump cutoff operation, that is, a simple inspection by the pump operation inspection.

That is, when a pump performance inspection is specified that specifies pump equipment on a specific floor, first the designated pump is set to the designated pump number X in S1, the inspection item and time are printed in S2, and then n is set as the measurement pump setting n. = 1, that is, the main pump equipment 10 in FIG.
Set -1. Then, in S4, static data of the main pump equipment 10-1 with n = 1 is measured and printed, and in S5, it is checked whether the insulation resistance is equal to or more than a specified value. In addition to the insulation resistance value, it may be possible to check whether the static data measured in S4 is within a specified value. When the static data is measured and the insulation resistance is checked in S6 until the designated pump number X, which is the inspection target, is reached, the process proceeds to S7, and it is determined whether or not only the designated pump is inspected. At this time, since it is in the mode in which the inspection of only the specific pump is designated, the process proceeds to S8, and the starting pump setting m is set to m = 1, that is, the main pump facility 10-1. Then, in S9, m is m = 1, that is, the main pump equipment 10-1.
Pump start control is performed, and after confirming the start in S10, data is measured and printed during the pump shutoff operation in S11, and the current value and rotation speed are checked in S12 to check whether the prescribed performance is satisfied. . The inspection by the pump shutoff operation in S9 to S12 is repeated until the designated pump number X designated as the inspection target in S13 is reached. Performs open control. For example, the second with the pump designation number X
If the relay pump facility 10-3 in the figure is specified,
After the inspection by the pump shutoff operation in S9 to S12,
At 14, the open control of the electric valve 36-3 provided in the test pipe 34-2 is performed.

Subsequently, the program proceeds to S15 of FIG. 5B, and it is checked whether or not the rated flow signal is obtained from the flow meter 38-3. If the rated flow signal is obtained, the program proceeds to S16, in which the electric valve 36-3 of the designated pump X is opened. Stop the operation, and in the next step S17, perform data measurement and printing during pump rated operation.

When the rated flow rate signal is not obtained in S15, the process proceeds to S150 to check the full opening, and if the full opening is confirmed, the process proceeds to S18 without performing the data measurement during the rated operation in S17. Of course, S15
If the full open confirmation is not obtained at 0, the inspection of S40 is canceled.

In S18, the electric valve of the designated pump X is controlled to be opened, and when a closed signal is confirmed in the next S19, the process proceeds to S20, and the stop pump setting t is set to t = X. That is, the pump that was started last is the stop target.

Subsequently, in S21, the pump having the stop pump setting t, for example, the pump stop control of the relay pump equipment 10-3 that was last started in FIG. 2 is performed, and after confirming the stop in S22, the time is t in S23.
= 1, that is, whether or not the main pump equipment 10-1 has been reached,
All pump stoppages are completed and finally the main pump equipment 10
When -1 is stopped, the process proceeds to S24. In S24, the measurement pump setting n = 1 is set in order to measure the static data after the stop, the static data is measured and printed in S25, and then it is determined in S26 that the measurement of the static data of all the pumps is finished. Then, a series of pump performance inspection is completed.

Next, the processing when the pump performance test is performed on all pump equipment up to the pump designation number X will be described.

First, from the setting of pump designated number X in S1, the designated number X in S6
Up to the process of measuring static data of all pump equipment and insulation resistance check is the same as when a specific pump equipment is specified, and when the end of measurement of all static data and insulation resistance check is determined in S6, In S7, check whether only the designated pump is checked. At this time, since it is an inspection of all pumps, the process proceeds to S27 and the measurement pump setting m is set to m = 1, that is, the main pump facility 10-1 located at the bottom of the building.

Then, in S28, the pump start control of the main pump equipment 10-1 with m = 1 is performed, after confirming the start in S29, the data is measured and printed during the pump cutoff operation in S30, and the current value and rotation speed are determined in S31. Check if the desired performance is obtained. If a predetermined performance is obtained by the pump shutoff operation, that is, the pump operation check in S31, the process proceeds to S32, and the motor-operated valve opening control of the pump in the shutoff operation state is performed. For example, with respect to the main pump equipment 10-1 in which the shutoff operation is first performed, the motor-operated valve 36-1 provided in the test pipe 34-1 is controlled to be opened.

Next, in S33 of Fig. 5B, the rated flow rate signal obtained from the flow meter 38-1 is checked, and if the rated flow rate signal is obtained, the flow proceeds to S34 to stop the motor-operated valve opening operation, and in S35, perform the pump rated operation. Measure and print time data. If the rated flow rate signal is not obtained in S33, full open confirmation is performed in S330. If full open is confirmed, measurement printing of rated operation data in S35 is not performed and the process proceeds to S36.

In S36, the motor-operated valve closing control of the m = 1 pump, that is, the motor-driven valve 36-1 of the main pump facility 10-1 is started, and S3 is started.
When the closed signal is confirmed in 7, the process proceeds to S38, and it is checked whether or not the measured pump setting m reaches the designated pump number X. If not, the process returns to S28 in Fig. 5A with m = m + 1, and the next pump equipment, that is, Perform similar deadline operation and operation test with actual flow rate for relay pump equipment 10-2.

When the value of the measured pump setting n matches the designated pump number X in S38, the process proceeds to S20, and as in the case of the inspection of only the designated pump, the pump equipment side started last by the processing of S20 to S26 is sequentially stopped. I will do it.

In the pump performance inspections of Figures 5A and 5B, when inspecting only the designated pumps, check the pumps on the floor below the designated pumps by the deadline operation, that is, the pump operation test. However, for simplification, the performance judgment in S12 in Fig. 5A is only discharge output and suction pressure, and static data measurement before and after starting S4 and S25. Printing may be omitted.

[Effects of the Invention] As described above, according to the present invention, when the automatic inspection command is received, the pump is started from the lowest pump equipment, and when the predetermined performance is obtained, the pump is turned on. The inspection control that starts the next pump equipment located and checks it is performed, and the lower pump is stopped, or the upper pump is started in a state where the prescribed performance is not obtained and it is judged as abnormal. Therefore, each pump equipment can be properly and automatically inspected in cooperation with other pump equipment located below.

In addition, regarding the inspection that specifies the relay pump equipment on a specific floor, the other pump equipment located under the pump to be inspected will be started sequentially from the bottom, but the pump performance after the start is all Does not target the measurement data of
By performing a simple inspection to judge limited items, it is possible to minimize the time delay until the original inspection of the designated pump and quickly perform the pump inspection of the designated specific floor.
