The communication port unit 222a includes first to Nth communication ports for implementing wired or wireless communication and is connected to the first to Nth remote control stations 221-1 to 221- Thereby allowing the master station 222 to receive the detection signal.

The port confirmation unit 222b sequentially checks whether each of the first to Nth remote control stations 221-1 to 221-N is connected for each of the first to Nth communication ports.

In this case, when the connection is confirmed for each of the first to Nth communication ports by the port checking unit 222b, a connection confirmation signal for the corresponding communication port is output.

When the connection confirmation signal is inputted from the port confirmation unit 222b, the automatic communication environment setting unit 222d sets the setting information read from the setting information storage unit 222e to the communication control unit 100 The communication environment is synchronized with the remote control station unit 221 with the setting information stepwise matching with the communication environment, and when the communication settings are synchronized with the realization of the communication environment through the above- (221).

At this time, the automatic communication environment setting unit 222d performs an operation of primarily matching the transmission speeds classified in stages among the setting information to the communication environment of the remote control station unit 221. When the matching is completed, it is possible to realize accurate and fast synchronization in the process of confirming the communication connection with the actual remote control station unit 221 by synchronizing the communication environment by sequentially matching the stop bit and the parity bit.

On the other hand, the communication environment automatic setting unit 222d outputs a synchronization completion signal when the communication environment synchronization with the communication port confirmed to be connected is completed.

In this case, when the communication environment synchronization completion signal is input from the communication environment automatic setting unit 222d, the port control unit 222c checks whether the communication port of the master station 222 is connected to another remote control station The master station 222 can be identified and synchronized with all of the communication ports configured in the master station 222 by repeatedly applying the process of controlling the communication unit 222b.

The setting information storage unit 222e stores setting information for communication environment synchronization in which the transmission speed, the stop bit, and the parity bit are cascade-connected.

Here, the setting information may be configured in the form of a data sheet in the form of a look-up table for the physical specification of data transmission for the actual communication environment of a plurality of remote control station units 221. [

For example, the transmission rate defining the size of data to be transmitted per second is stored in the range of 9600 bps to 115200 bps, for example, And information about even, odd, and none for the parity error bit in combination with the case of two stop bits.

When the detection signal transmitted from the sensor 100 for detecting each of the plurality of water supply and sewage treatment facilities exceeds a reference signal capable of determining a dangerous situation, the dangerous state control unit 222f transmits a detection signal exceeding the reference signal And transmits an image acquisition signal requesting an image of a place where a corresponding detection signal is generated to the detected remote control station unit 221. [

This makes it unnecessary to overload the communication traffic by randomly and unintentionally generating image information of various places where the respective sensors 100-1 to 100-N are located and transmitting the generated information to the center indispensably, It is to solve the difficulty of judging whether or not it is individual.

That is, a reference signal for determining that the sensor is actually in a problematic situation or a dangerous situation is set, and it is determined whether or not a detection signal transmitted from the sensors (100-1 to 100-N) And the signal for requesting the acquisition of the image of the moving image or the still image, which is large-capacity data, is transmitted only when the detection signal exceeds the reference signal, thereby effectively solving the above-mentioned problem.

Next, the communication module 230 performs communication with the management server 300 using a wired communication module (not shown), a wireless communication module (not shown) and / or an internet module (not shown).

The wired communication module (not shown) can communicate between the remote control device and the dedicated line modem by RS-232 or RS-422 using a dedicated line provided by the communication company (for example, a leased line provided by Korea Telecom) In this way, the general manager provides wasted information on facilities, etc. to the manager who manages the waterworks facilities, the sewage facilities, and the water management facilities.

A wireless communication module (not shown) is used to perform wireless communication with an external facility manager such as Zigbee, RF, WiFi, 3G, 4G, LTE, LTE-A, WiBro Broadband Internet) can be used.

The Internet module (not shown) is for performing the Internet in an external facility manager and a dynamic IP network environment. The Internet module (not shown) includes a central control device (not shown), a network management module (not shown), an ethernet A router (not shown) and an Internet modem (not shown).

Hereinafter, the central control unit assigns a private static IP address and a port number from the network management module to the PC, a smart phone, a PDA, and the Internet carried by an external facility manager.

The network management module is a software module mounted on the central control device and serves to relay and control data communication using a dynamic IP address and a private static IP address.

That is, the network management module receives the data transmitted from the outside via the Internet network, changes the destination floating IP address of the communication data to the private fixed IP address according to the port number of the received communication data, send.

Ethernet is a bus-structured local area network (LAN) that allows the central control unit to send and receive data through it.

The water treatment remote monitoring and control apparatus using the intelligent system according to the present invention detects the water quality of the water resources through a sensor unit such as a water quality sensor and controls the RTU terminal unit 100. In particular, And an intelligent water quality sensing means for measuring the water quality by the depth of the water.

As shown in FIGS. 4 and 5, the water quality sensing means 400 includes a tower 410 vertically installed in a central portion of a water-processing type water treatment facility (water supply facility, sewerage facility, water management facility) The elevating means 420 is installed inside of the RTU terminal unit 410 and moves up and down step by step at a predetermined time period under the control of the RTU terminal unit 100. The elevating means 420 is stepped up and down along the tower 410 by the elevating means 420 And a water quality sensor 430 for detecting water quality of the water resources stored in the water treatment facility 1 by water depth.

The tower 410 includes a tower main body 411 having vertically vertical elevation passages therein and a water quality measuring device 411 formed on the tower main body 411 so as to pass through both sides of the tower main body 411 along the front and rear sides, (412).

The tower main body 411 is fixed at its bottom to the bottom surface of the water treatment facility 1 by anchoring. In addition, the tower main body 41 can be supported through a plurality of inclined bracings 413.

The multi-tier water quality measuring hole 412 is a hole for supplying the water quality sensor 430 with the water depth corresponding to the depth of the water quality measurement by the water quality sensor 430 and is arranged in a line in the tower main body 411 Respectively. That is, the water source introduced through the water quality measurement hole 412 on one side is discharged through the water quality measurement hole 412 on the other side after the water quality measurement.

In addition, when any one of the multi-tier water quality measurement holes 412 corresponds to the water quality sensor 430 and the water quality measurement is performed at the corresponding depth and the water resources are introduced through the remaining water quality measurement hole 412, A door 414 is provided for opening and closing the remaining water quality measuring hole 412. [ That is, the door 414 is mounted on the water quality measurement hole 412 of all heights and opens the water quality measurement hole 412 at the depth for measuring the water quality by the water quality sensor 430 and closes the rest.

The door 414 may be applied to both the water quality measurement holes 412 disposed at the same height or may be applied only to the inlet side corresponding to the water quality sensor 430. [

Under the control of the RTU terminal unit 100, the door 414 is installed to be movable up and down by a motor rotating in both directions to open and close the water quality measuring hole 412. A rail for raising and lowering the door 414 is formed on the outer peripheral surface of the tower main body 411.

The water quality measuring hole 412 on the inflow side is formed so that the diameter gradually increases toward the inside so that the water source can be rapidly introduced toward the water quality sensor 430 while the water inside the tower body 411 is quickly discharged, The water quality measuring hole 412 is formed such that the diameter gradually increases toward the outside.

The elevating means 420 includes a lifting rod 421, a lifting motor 422 for rotating the lifting rod 421 in both directions and a lifting carrier 423 for lifting and descending the water quality sensor 430 stepwise on the lifting rod 421 .

The elevator shaft enclosure 421 is a screw rod having a thread on the outer circumferential surface thereof and is vertically disposed in a hoistway inside the tower body 411 to be rotatable in place.

The elevating motor 422 is mounted on the top of the tower main body 411 and connected to the elevating shaft rod 421 to rotate the elevating shaft rod 421 in both directions so that the elevating carrier 423 is raised by the forward rotation, So that the lifting carrier 423 is lowered.

The lifting and lowering carrier 423 includes a nut portion having a thread on the inner circumferential surface thereof and is screwed to the periphery of the lifting rod 421 through the nut portion.

The elevating carrier 423 is preferably equipped with a water quality sensor 430. The water level sensor 430 may be connected to the probe of the water quality sensor 430 and the water quality sensor 430 may be protected by a groove- A hole through which the water source is introduced is provided in front of the water inlet.

The elevating carrier 423 ascends and descends stepwise (step corresponding to the position of the multi-stage water quality measuring hole 412) through the elevating rod 421.

An induction plate 424 is applied so that the water source introduced through the water quality measuring hole 412 flows into the probe of the water quality sensor 430, that is, the water source is not lost to the outside of the water quality sensor 430.

The guide plate 424 is made of elastic rubber or the like, and the free end of one side is in close contact with the inner circumferential surface of the tower main body 411 to ensure watertightness.

At least one lift guide rod 425 is applied so that the lift carrier 423 can only move up and down. The lifting and lowering guide rod 425 is installed in the same direction as the lifting rod 421 and is vertically penetrated to the lifting carrier 423 so that the lifting and lowering carrier 423 is caused to ascend and descend by the rotation of the lifting and lowering rod 421, It is preferably square.

The lifting and lowering carrier 423 is structured such that the lifting and lowering carrier 423 is eccentrically installed and the periphery of the lifting and lowering carrier 423 is preferably disposed on the opposite side to the water quality sensor 430 in order to prevent the lifting carrier 423 from tilting due to eccentricity A weight balance 426 is mounted on the periphery.

The intelligent water quality sensing unit 400 configured as described above operates under the control of the RTU terminal unit 100 and operates the motor 422. For example, the water quality measurement is performed at regular time intervals and the water quality is measured at each depth Respectively.

The RTU terminal unit 100 gives a positive polarity to the motor 422 so that the elevation shaft rod 421 rotates in the forward direction or the reverse direction with negative polarity and the degree of rotation of the elevation shaft rod 421 is controlled by the elevation carrier 423 So that the water quality sensor 430 corresponds to any one of the water quality measurement holes 412 among the plurality of water quality measurement holes 412. Of course, since the water quality of each depth is measured through all the water quality measurement holes 412, the water quality measurement is sequentially performed from the water quality measurement hole 412 disposed at the upper part.

When the elevating carrier 423 moves to the water quality measurement position, for example, water quality measurement is performed after elapse of 5 seconds in order to stabilize the water flow. The water resources inside the water treatment facility 1 pass through the water quality measuring hole 412, The water source is stagnated in front of the water quality sensor 430 without flowing water to the outside of the water quality sensor 430 by the guide plate 424 at this time. In addition, the remaining water quality measuring hole 412 is closed by the door 414, and the water quality sensor 430 is capable of measuring an accurate water quality at the corresponding depth.

After the water quality measurement is completed, the elevating carrier 423 moves to the water quality measuring hole 412 at the next position and measures the water quality at the corresponding depth by the above-described method.

The management server 300 manages the water quality value of each water depth measurement point 412 of the multi-tiered water measurement system 412, and thus detects water quality values at every place of the water resources stored in the water treatment facility 1, will be.

For example, a sterilizer (not shown in the drawings, all the sanitizing devices for removing contaminants can be provided) is provided in the periphery of the tower main body 411 so as to correspond to the multi-stage water quality measuring holes 412 in a one-to- 300) and / or the RTU terminal unit 100, if the pollution degree of the water quality measured in the multi-stage water quality measuring pond is equal to or higher than a certain concentration (it is not limited to a specific value since it can be varied as a reference concentration), the sterilizer And controls the operation.

6 and 7, the present invention can divide the interior of the water treatment facility 1 into an inlet side and an outlet side with respect to the tower 410 as a center, for example, in accordance with the position of the tower 410 The partition wall 500 is divided into an inlet side and an outlet side, and one or more water gates may be applied to the partition wall 500.

The management server 300 and / or the RTU terminal unit 100 closes the water gate to prevent the water source on the inflow side from being discharged to the discharge side when the water quality measurement value by the water quality sensor 430 is measured as a highly contaminated state, In this state, the water source on the inflow side can be cleaned.

At this time, the multi-stage water gates 510, 520 and 530 are constructed in accordance with the multi-tier water quality measuring holes 412, and if the water level measured by the water quality measuring hole 412 is higher than the reference pollution degree, And conversely, when the water level is lower than a predetermined amount higher than the reference contamination, the water gates 510, 520 and 530 can be controlled to be opened. For example, when the three-stage water quality measuring hole 412 is applied, if the measured value of the two or more water quality measuring holes 412 is higher than the reference contamination degree, all the water sills 510, 520 and 530 are closed to perform the purification operation on the inlet side And if the value measured in one or less water quality measuring holes 412 is lower than the reference pollution degree, the water doors 510, 520 and 530 are opened and discharged to the discharge side.

Alternatively, it is possible to open the corresponding water gates 510, 520, and 530 to discharge water resources having a low level of contamination among the multiple water gates 510, 520, and 530. Of course, due to the discharge of water resources, the water level of the water source will be lowered, so that the pollution degree will be changed, and the opening and closing operation of the water gates 510, 520 and 530 will be changed according to the change in the water quality measurement value by the water quality sensor 430, .
