According to another aspect of the present invention, the microphone is disposed on one side of the outer surface of the pressure pump 110, and is formed in a chamber shape having an open bottom. The microphone is mounted on the pressure pump 110, And an ambient noise blocking unit 170 for blocking noise from being input to the microphone.

As described above, according to the present invention,

First, the rotational speed of the driving motor 111 mounted on the pressure pump 110 is calculated and the display image of the shape rotating at a rotational speed proportional to the rotational speed is externally displayed, The operation state of the pressure pump 110 can be grasped intuitively by recognizing the driving speed of the driving motor 111 through the speed at which the display image rotates.

A display 130 for outputting the display image is mounted on the case 141 of the control module 140 and is connected to the control panel 142 through a ring that surrounds the control panel 142 on which the operation button 143 and the display window 146 are disposed. And can be maximally sized within the limited size of the case 141 of the control module 140, thereby increasing the visibility of the displayed display image.

A rotary part 150 including a support frame 151 and a rotary shaft 152 is mounted on the upper part of the pressure pump 110. The case 141 is disposed on the upper part of the support frame 151, Since the pressure pump 110 is installed in a designated space within the installation space and the door or the moving passage entering the interior space is fixed, When the angle of viewing the pump 110 from a long distance is limited, the left and right angles of the case 141 are adjusted to be easily viewed by the manager so that the display image displayed on the display 130 is identified It provides an effect that can be done.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The pump device 100 provided with the operation state display function according to the preferred embodiment of the present invention displays the display image of the shape rotating according to the rotation speed of the drive motor 111 mounted on the pressure pump 110, As shown in FIGS. 1 to 4, the pressure pump 110, the rotation sensing unit 120, and the rotation sensing unit 120 are installed in the pump unit 100, A display 130, and a control module 140.

First, the pressure pump 110 is a fluid pump that pumps and pressurizes a fluid. The pressure pump 110 is mounted on a conduit connected between a source of water supply and a customer and is driven by a control signal And pressurizes the fluid supplied from the water source side to a predetermined pressure and discharges it to the customer side.

The pressure pump 110 includes a driving motor 111 for rotating and a chamber 112 for providing a space in which fluid is pressurized. And the impeller or the cylinder rotating at high speed is connected to receive the rotational force, and the fluid can be pushed and discharged by the pumping operation according to the rotation.

The rotation sensing unit 120 senses the rotation speed of the driving motor 111 and is disposed opposite to the rotor in the driving motor 111 to detect a change in the magnetic field due to the rotation, And a rotation sensing signal is transmitted through a signal line connected to the control module 140 and used as basic data necessary for displaying a display image of the display 130. [

The display 130 is a display means for outputting a forest that rotates in proportion to the rotational speed of the drive motor 111. The display 130 has a ring shape or a circular shape as shown in Figs. The unit blinking unit 131 of the display unit 130 sequentially blinks to display the rotated display image.

Here, in order to display the display image in a rotating form using each unit blinker 131, the unit blinker 131 of the first (1) is firstly turned on at first, The unit blinker 131 of the second unit is turned on alone and the unit blinker 131 of the third unit is turned on at the moment when the unit blinker 131 is extinguished as well It is possible to output a display image such that the illuminated light is rotated along the outer periphery of the display 130. [

Each of the unit blinkers 131 is mounted on a case 132 formed in a ring shape at a predetermined interval along the circumference of the case 132. Although not shown, the unit flasher 131 may include a light emitter for dispersing the light of each unit flasher 131 Plate can be placed.

In addition, when the display 130 is a circular shape rather than an annular shape as shown in the figure, the unit blinking unit 131 may have a sector shape spaced apart at a predetermined interval along the circumference.

The control module 140 is a control means for centrally controlling the display image output of the display 130. The control module 140 calculates the rotation speed of the driving motor 111 using the rotation sensing signal of the rotation sensing portion 120, When the rotation speed is increased, the sequential blinking period (0.05 seconds) of each unit blinker 131 is increased. When the rotation speed is decreased, the sequential blinking period is increased to increase the rotation speed of the drive motor 111 The rotation speed of the display image displayed on the display 130 is increased or decreased.

Accordingly, when the discharge amount of the fluid increases due to the operation of the operation button 143 or the pressure pump 110 or the flow rate sensor or the like and the rotational speed of the driving motor 111 is increased, the control module 140 Based on the rotation detection signal, controls the rotation speed of the display image displayed on the display 130 to increase together. If the rotation speed is slowed due to the decrease in fluid discharge amount, the rotation speed of the display image is slowed down It can be controlled.

The rotation of the drive motor 111 mounted on the pressure pump 110 can be performed by the configuration and the function including the pressure pump 110, the rotation sensing unit 120, the display 130 and the control module 140. [ A display image of a shape that calculates a speed and rotates at a rotation speed proportional to the rotation speed is displayed externally so that it can be recognized whether the display image is driven by the lighting color or rotation of the display image, The operation state of the pressure pump 110 can be grasped intuitively by recognizing the rotation speed of the motor 111. [

1 and 2, the control unit 140 includes a case 141 which forms an outer shape of the control module 140, a case 141 which is disposed on the front surface of the case 141, A control panel 142 having a plurality of operation buttons 143 for outputting an input signal for controlling a set state or a driving state and a display window 146 for displaying each set value and a driving state in a character or numerical value, And a control circuit unit 144 that is configured inside the case 141 and drives and controls the pump device 100 in accordance with the input signal of each operation button 143. [

In addition, the display 130 may have a ring shape surrounding the periphery of the control panel 142 and may be disposed on the front surface of the case 141.

As described above, the rotation speed of the driving motor 111 mounted on the pressure pump 110 is calculated and the display image of the shape rotating at a rotation speed proportional to the rotation speed is displayed externally, And recognizes the rotational speed of the driving motor 111 through the speed at which the display image rotates, thereby providing an effect of intuitively grasping the operating state of the pressure pump 110. [

5, the pump 100 according to the preferred embodiment of the present invention includes a support frame 151 mounted on the upper portion of the pressure pump 110, And a turning unit 150 including a pivot shaft 152 disposed upright.

The case 141 may be mounted on the upper portion of the support frame 151 and may be mounted on the pivot shaft 152 so as to be rotatable in the horizontal direction. Therefore, the rotational speed of the driving motor 111 mounted on the pressure pump 110 is calculated and the display image of the shape rotating at a rotational speed proportional to the rotational speed is externally displayed, The operation state of the pressure pump 110 can be grasped intuitively by recognizing the driving speed of the driving motor 111 through the speed at which the display image rotates.

6 (a), the display 130 is cased in the form of a separate module separated from the case 141, and the lower end of the display 130 is mounted on a tilting frame 145 horizontally disposed on the case 141 And can be arranged in a state in which they are arranged upright on the case 141 or adjusted in inclination angle while being tilted in forward and backward directions. Therefore, by controlling the inclination angle of the display 130 according to the installation height of the case 141, the output display image can be outputted so as to face the viewing direction.

6 (b), the tilting frame 145 is formed as a module separate from the case 141, and the lower end of the tilting frame 145 is pivotally mounted on the case 141 The left and right angles of the display 130 can be adjusted while being rotatably mounted in the horizontal direction.

The pump device 100 according to the preferred embodiment of the present invention monitors whether the pump device 100 is operated in a driving state requested according to an input signal of the operation button 143 or a set programmed item, And a failure detection unit 160 for determining whether or not the failure has occurred.

Here, the control module 140 receives a failure detection signal from the failure detection unit 160 and displays a failure state or light color distinguishable from the display image displayed on the display 130 during normal operation when a failure occurs, (130).

For example, when the control unit 140 controls the unit unit blinking unit 131 to turn blue in the normal operation, the control module 140 controls the unit unit blinking unit 131 to be turned on or off in a yellow or red state, (131) is flickered simultaneously so that the normal operation and the occurrence of the failure can be clearly distinguished.

In this way, the control module 140 controls the display 130 so that the display 130 is displayed in a lighting state or lighting color different from the display image displayed on the display 130 during normal operation when a failure occurs, It can be intuitively recognized. In other words, when the warning and key fault occurrences are classified into the lighting state or the lighting color and are displayed on the display 130, the manager can easily recognize the middle of the failure contents without looking directly at the display window 146 of the control panel 142 can do.

In addition, the failure detection unit 160 outputs a failure detection signal by dividing an alarm general that can be reset by a reset according to a failure detection state and a used general who requires an A / S, The control module 140 may control the display 130 to distinguish the occurrence of a fault and the occurrence of a fault as a light or a light color.

The warning general is a temporary drive error state such as an overcurrent detection and an overload operation detection. In the case of the second-generation general-purpose general, the symptom of the warning general occurs repeatedly in excess of the set number, For example, when the pump device 100 is forcibly driven as shown in FIG.

For example, at the same time, the unit flushing unit 131 is driven to be rotated in a first color (for example, blue) as shown in FIG. 7A, and is displayed as a second color (for example, yellow) (For example, red) at the time of occurrence of a heavy load, thereby restoring the power to the initial state by the reset program of the control module 140. In addition, In case of a trouble, immediately contact the maintenance company to receive the A / S by the specialist.

Meanwhile, the rotation sensing unit 120 may sense the rotational speed of the driving motor 111 using the Hall sensor or the encoder described above. In addition, the driving noise generated during the operation of the pressure pump 110 may be input And outputs it as an acoustic sensing signal which is an electrical signal.

In this case, the control module 140 may store reference data for determining the rotation speed of the driving motor 111 based on the sound sensing signal, and may include an acoustic sensing signal output from the rotation sensing unit 120, The rotation speed of the drive motor can be indirectly calculated by comparing the reference data.

The rotation sensing unit 120 is a microphone for receiving a driving noise generated during operation of the pressure pump 110 and outputting a sound sensing signal. The control module 140 stores reference data for each sound sensing signal, It is possible to indirectly calculate the rotational speed of the drive motor 111 that varies proportionally with the change of the drive noise.

Since it is unnecessary to install a Hall sensor or an encoder for sensing the number of rotations inside the driving motor 111, it is possible to freely design the driving motor 111 and drastically reduce the system construction cost. In addition, if a microcontroller for calculating the rotation speed according to the acoustic sensing signal of the microphone separately from the control module 140 is prepared and the display 130 is connected to the microcontroller for signal connection control, It is independent from the drive parameters of the pump 110, so that the pump device manufactured in a state in which the display function is not provided can be independently mounted without any signal connection to calculate its own rotation speed and output the display image.

Here, as shown in FIGS. 1 and 8, the microphone may be disposed at one side of the outer surface of the pressure pump 110. In addition, the pump device 100 according to the preferred embodiment of the present invention has a chamber shape having an opened lower portion and is mounted on the pressure pump 110 to cover the microphone, And may further include a blocking unit 170.

In this case, the inner circumferential surface of the peripheral noise isolator 170 may be provided with a vibration and vibration such as a sponge, rubber, silicone, and the like in order to block vibrations due to driving from being transmitted to the inside of the surrounding noise- It is preferable that the anti-vibration member 171 made of a material capable of restraining is disposed. In addition, when the microphone is mounted on the outer circumferential surface of the pressure pump 110, it is preferable that the microphone is mounted on the inside or the surface of the anti-vibration member 171 because internal vibration due to driving can be transmitted. Therefore, it is possible to block the ambient noise from being input to the microphone, so that it is possible to minimize the calculation error of the rotation speed due to the noise.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge.
