The present invention relates to a remote automatic control system for small unmanned water supply and pressurization station, and more specifically, it is installed in the pressurization station, and it is possible to monitor the operation status of the water supply facilities for each pressurization station at a remote place through a single control device connected to the Internet network. The present invention relates to a small unmanned water supply and pressurization remote automatic control system that can directly control all the peripheral devices installed in the pressure station.

In general, the high ground is far from the water purification plant, so the frictional loss of the water supply pipe is high, and the altitude is high, which causes inconvenience in using the pressure drop at the distal end of the pipe. The water supply system is operated by using a booster pump system that maintains a constant discharge pressure of about 1.5 ~ 2Kg / Cm at all times.

The water supply pressure station is installed to supply water smoothly to highlands and hills where water supply pressure from the water purification plant cannot supply water only due to the high altitude difference with the plains. As it needs to be installed, it is being converted into an unmanned water supply and pressure plant in consideration of the efficiency of water supply work and the scope of management work.

The above water supply and pressure station is difficult to secure the space on the ground for installing the building structure, and it is installed to dig a bit underground to protect the pipes from freezing caused by the cold in winter, in the case of the underground bit is a lot of moisture When the rain occurs during the rainy season and heavy rain occurs, rainwater penetrates into the underground bit so that the corrosion of the equipment proceeds faster. Occurs.

In the water supply pressurizing station, a drainage pump is installed inside the pressurizing station to prevent water leakage or flooding due to rainwater. However, when the flow rate is larger than the discharged flow rate or when an abnormality occurs in the drainage pump, the whole pressurizing station is closed. There is a need to flood and require a fresh system installation.

In addition, the water supply and pressure station is operated under poor conditions, when the life of electronic components vulnerable to moisture is shortened or the system is stopped due to abnormal occurrence, check the singular situation due to the system stop by telephone notification of the residents, and dispatched to the site After determining the cause, it is operated in a way to be requested by the installation company, there is a problem that it is difficult to even prevent the singular phenomenon or even immediately.

In addition, the water supply pressure station automatically stops the system in order to protect the pump when there is air in the pipeline flowing into the pressurization station due to breakage of the pipeline or freezing caused by freezing. It is necessary to go out to find the cause, and it takes a lot of time to take action, so residents have to accept the inconvenience of singular until the action is completed.

The water supply equipment as described above requires a system that can check the operating status, but the existing operating status check system can check the operating status of the water supply equipment only in the central monitoring room equipped with a monitoring control equipment, and can monitor the status The range is also limited to monitoring the water level and the flow rate of the reservoir, so that it is difficult to grasp the overall operating state such as the current consumption and the pressure monitoring according to the pump operation.

More specifically, the conventional water supply control system receives a signal from the pressure sensor mounted on the discharge side and controls the booster pump with an inverter so that the discharge pressure matches the set pressure even if the flow rate changes, and the remaining pump controls the insufficient flow rate of the booster pump. It consists only of simple water supply pressurizing device, which does not have functions related to the control of peripheral devices installed in the pressure station, and uses a analog signal to control the speed of the inverter. At the same time, accuracy drops.

In addition, some of the conventional small pressurized stations have to install a separate Telemetering Tele Control (TMTC) control panel using a dedicated communication line in the existing pump control panel connected to the water supply facility to monitor the pump control panel in the central monitoring room. However, due to the mismatch between the communication interface between the TMTC control panel and the pump control panel, it is impossible to determine the exact operating state of the pump control panel in the central monitoring room, so that not only the detailed data of the pump control panel in the central monitoring room but also directly operate the inverter that operates the pump. In addition, when the CCD camera is installed to check the operation environment in the pressurized field from the outside, a problem arises in that an additional xDSL communication line is installed in addition to the dedicated line.

The present invention is devised to achieve the above object, the object of the present invention is an integrated control panel that does not need to install a separate TMTC control panel, the RS-485 port of the communication means provided in the remote control device of the pump It is configured to enable data communication with the inverter that controls the number of revolutions, and installs a single remote control device that transmits / receives data for each pressurized field by connecting to peripheral devices in the pressurized field. It is to provide a small automatic unmanned water supply pressurized remote control system that can check the operation status of the water supply equipment by selecting the pressurized station and directly control all the peripheral devices including the inverter from the remote site.

In addition, another object of the present invention is to duplicate the controller of the remote control device installed by each pressure field to the main controller and the auxiliary controller to monitor the mutual operation state of the controller, when the main controller has an error, it is automatically After detecting the system, it is to provide a small unmanned water supply and pressure remote control system that secures the control of the system from the main controller to prevent the singular phenomenon in the area where the pressure station is installed and at the same time generates a signal to the remote site to inform the system of the abnormality.

In addition, another object of the present invention is to connect the Ethernet port, which is a communication means provided in the main controller for data communication with the outside to be connected to the IP sharer to the Internet network, and to mount the CCD camera connected to the IP sharer in the pressure field It is to provide a small unmanned water supply and pressure remote control system that can directly check the state of the selected pressure field by remotely accessing the CCD camera through the internet network from the central monitoring room and anywhere outside without expanding the communication line. .

The present invention has the following features to solve the above problems.

The present invention connects to a server computer via the Internet network, transmits and receives data, uses various peripheral device information in the pressure field collected from the auxiliary controller, and commands various drive device commands in the pressure field to the auxiliary controller, and stores various state data in its own memory. The controller receives the signals from various sensors in the pressure field and transmits the data to the main controller, and acquires command and status data through RS-485 communication with the inverter controlling the rotation speed of the pump. It is composed of auxiliary controller which receives various driving device operation command from pressurization field and performs it. The main controller for controlling the pressurized field is forced to reset the main controller only three times when the state data is not periodically received from the auxiliary controller so that the auxiliary controller can be restarted. Auxiliary controller also forcedly resets the main controller only three times when the normal command command is not received periodically from the main controller. If the normal command data is not received even after three forced resets, the auxiliary controller controls the pressure field by securing control of the pressure field system. A remote control panel composed of the main controller and the sub-controller and installed in each of a plurality of pressurized fields installed in each region; The operation information collected through the remote control panel and the Internet network is converted into a DATABASE, and the server program for processing and outputting the operation information into necessary data using a program and connected to the server to obtain the floating IP information of the pressure field It consists of a client program that directly connects the CCD camera installed in the pressurization cabinet, displays its image, requests and displays various operating state data from the server, and directly remotely controls the devices in the pressurization cabinet.

The central monitoring room server 200 stores the operation information collected from all the remote control devices 100 connected to the data base, and in response to the periodic data request of the connected client 300. Send and receive driving information. The client 300 processes and outputs the received data in real time to the various monitoring windows as necessary data, and transmits various setting data of the remote control apparatus 100 to the central monitoring room server 200.

 More specifically, the communication between the server 210 and the remote control device 100 is configured in the server mode so that the remote control device 100 is always connected, the remote control device 100 is Once the connection is made, the remote control device 100 first asks for an ID and checks whether the returned ID is registered in the central monitoring room server 200. If the ID is not registered, the connection is blocked. do. If the registered ID is matched, the operation status data is periodically requested to the remote control device 100 about 2 or 3 times per second, and the data is stored in the memory, and the data is stored every 1 minute. When the human body sensor operates, a separate LOG file can be saved for inquiry. The server program 220 stores a specific memory of the remote control device 100 every 20 seconds so that reconnection with the remote control device 100 can be made in the shortest time when communication is disconnected due to various factors such as a failure of a communication line or a failure of a MODEM. Sends PING CHECK data to RANDOM to. The remote controller 100 stores the received PING CHECK data memory and compares it with the previous data every 30 seconds. If there is no change in the value, the remote controller 100 considers the abnormality in the communication line and closes the current socket to close the server program. After the connection with the server 220 is terminated, the port is increased by one, and a socket is formed again to connect to the server program 220. The server program 220 transmits the next read request data when the periodic read data transmitted to the remote controller 100 is returned in accordance with the requirements, but if the data is not returned within 20 seconds, the remote control device Terminate the communication connection with (100). On the other hand, when the server terminates the connection or an error occurs in the communication line, when the remote control device 100 does not make a connection with the server program 220 within 2 minutes even when trying to reconnect by comparing the PING CHECK data every 30 seconds It automatically turns off the power of the Broadband Router and xDSL MODEM, and then turns the power on again to replace the RESET function of the communication device.

The screen of the server program 220 is composed of a monitoring window and a report output window. The monitoring window displays the connection information of the remote control apparatus 100 and the client program 310. The output window inputs a condition from the stored data base to display an EXCEL FILE. It consists of output inquiry to be automatically saved to the screen, recording inquiry on the screen, log inquiry of abnormal and pressurized changes, remote control device registration, and other management windows to manage client program ID, password, and authorization.

The client program 310 is composed of a main program 320 and a detailed program 330 and the main program 320 is configured to grasp at a glance the important operating conditions of all the pressurized fields in a zone to start the pump for each pressurized field. It is displayed graphically, and the suction pressure, discharge pressure and system operation / stop status, communication connection status and abnormal status are clearly displayed. If any error occurs, the phrase “Error occurrence” flashes in red and The voice message corresponding to the error is repeatedly output through the speaker.

The detailed program 330 is executed by clicking the connection button of the corresponding pressure field in the main program 320, and the voltage, current, system operation rate of the primary power source in the pressure field, operation / stop status of the pressure pumps 1 and 2, and DC BUS of the inverter.

In summary, the remote automatic control system according to the present invention automatically controls all peripheral devices in the small unmanned water supply and pressure station using the remote control device 100, and the data is installed in the central control room via the Internet through one floating IP. It is connected to the central monitoring room server 200 with IP to transmit and receive real-time operation data. The server program 220 installed and operated on the server stores and stores various operating states and logging data received from the remote control device as DATABASE, and confirms a predetermined request to a connection request to the central control room administrator or the client 300 of the local government office. After the procedure, the client program relays the data to and from the pressure station. In this way, the client program 310 monitors the state of the pressure field through the central monitoring room server 200, and can control various driving devices in the pressure field directly through various commands if necessary, and obtains the floating IP of the pressure field from the server to obtain a CCD camera. Is a networked system that directly connects and displays images.

Hereinafter, a remote control method of a small unmanned water supply and pressure station remote automatic control system having the above structure will be described based on algorithms of programs embedded in the system.

First, when power is supplied to the remote control apparatus 100, the server attempts to access the central monitoring room server 200 based on the stored IP address and port information of the server computer, and maintains the on-line state and requests the server. It transmits the periodic data, and the command data is processed according to the data type and then transmitted back to the central monitoring room server computer. In addition, the main controller 120 allocates a predetermined amount of memory (SRAM) 123 to store various data returned from the inverter 110, and inputs the display panel 140 to the input of the display panel 140 or the client program 310. After the status memory data request command is transmitted to the inverter 110 based on the inverter 110 communication-related setting data (including control variables) obtained from the input, when normal data is returned from the inverter 110 within a predetermined time. If the various data are mapped to the designated memory 123 with the memory of the inverter 110 one-to-one and used in the system, and the normal data is not returned or the normal data is not returned within a predetermined time, the remote control device 100 Clear the Inverter access related memory bit.

In the communication between the main controller 120 and the inverter 110, the auxiliary controller 130 is always monitoring the communication data between the main controller 120 and the inverter 110 through RS-485, and continuously abnormal When data is found, the reset terminal of the main controller 120 is electrically forcibly reset, and if it does not normalize thereafter, the system is directly controlled.

Next, in mutual data communication between the main controller 120 and the sub-controller 130, various setting parameters related to the operation of the system while communicating with each other through RS-232 are connected to the main controller 120 and the sub-controller. Simultaneously stored or modified at 130, data packets formatted at regular intervals (approximately 400 ms) are transmitted / received to each other.

Accordingly, when the main controller 120 does not receive the standard data packet within a predetermined time, the main controller 120 counts the number of times, and if the normal data is not received continuously 10 times or more, the main controller 120 resets the RESET terminal of the auxiliary controller 130. By maintaining the low level for a predetermined time (approximately 500mS) to the secondary controller 130 is rebooted, so that the normal program can be performed.

Similarly, the sub-controller 130 also checks the data packet transmitted from the main controller 120, if an abnormality occurs in the data, by forcibly reset (Reset) in the same manner as above to perform a normal operation, the elapse of a certain time Even if normal data reception is not performed, the auxiliary controller 130 turns on the RS-485 relay connected to the main controller 120 to turn on the electrical circuit between the main controller 120 and the inverter 110. Control the system directly after controlling the system. As a result, even if a failure occurs in the main controller 120, the sub-controller 130 drives the system stably in place of the function.

Finally, the operation of the client program is divided into two types, one for the administrator who can give various commands to the system, and one for the monitoring that can only query the operation status and abnormal details. The server program 220 distinguishes whether the client program 310 is for an administrator or a monitor by using ID information stored in advance when the client program 310 is connected. When the client program 310 is for monitoring, the server program 220 ignores all command commands to perform only a monitoring function. Do it. Surveillance programs are not directly related to the operation of the system, but provide the function of jurisdiction / locality / dong office to immediately identify the cause of the report. In addition, when an error occurs, the error message window is automatically popped up (POP-UP) and at the same time, the administrator can recognize the dissolved voice message through a speaker connected to the computer with a previously stored abnormal wave file.

As described above, the present invention is connected to the peripheral devices in the pressure field including the inverter for controlling the operation of the pump is connected to each of the pressure field is a single remote control device capable of internal data communication and data communication with the outside through the communication means There is no need to install a separate control panel, so there is a benefit in terms of installation cost and installation space.It checks the operation status of the water supply equipment for each pressurized station at a remote location, and directly sets and inquires the control variables related to all devices of the control system. It is possible to directly diagnose the pressurized water supply facilities at remote sites and to operate and manage them quickly.

In addition, the present invention is to duplicate the controller of the remote control device to monitor the mutual operation status, so that if any one of the abnormalities automatically recovers to operate the system, if the failure of the main controller can not recover the auxiliary controller Securing the control of the system to prevent the singular phenomenon in the area where the pressure field is installed, and if an error occurs, the short message service (SMS) function through the mobile phone and the error monitoring signal to the central monitoring room and the client program installed in the jurisdiction / town / dong By transmitting immediately, it is possible to quickly detect abnormalities in the system and take action to secure stability and reliability of the system.

In addition, the present invention does not use a dedicated line, which is a communication means of Telemetering Tele Control (TMTC), but a remote control device with a built-in Ethernet port is connected to a server computer using an xDSL MODEM using a general dynamic IP. Is done. The client program can be monitored and controlled by accessing the server from anywhere in the world, which is the Internet, and can obtain the dynamic IP information of the pressure field from the server computer and directly connect the CCD camera of the pressure field to view images. In other words, this system uses a single xDSL line that uses a low-cost floating IP, and maintains the system by directly accessing the CCD camera from the client program as if it is connected to a camera with a fixed IP from a remote site. The maintenance cost can be reduced because there is no need to operate a separate TMTC group in the central monitoring room, and the system can be monitored and controlled from outside the central monitoring room.
