BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote terminal device for a water and wastewater observation system and, more particularly, to a remote terminal device for a water and wastewater observation system, including a control function for each facility, To an integrated control and monitoring system for water and wastewater facilities that can be remotely performed in an economical and environmentally friendly way.

Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

Generally, most water and sewerage systems are buried underground, and after a proper period of time, they are corroded by old age, or are damaged due to natural or artificial external force.

As described above, in the case of the water supply, the supply of the water supply is disrupted, or in the case of the sewer, the water pollution and the like are generated. In addition, economic damage is caused to recover the water and various damages are caused.

In order to solve such a problem, conventionally, a public facility that manages a water supply facility uses a leakage detection system such as a blue sound pipe or the like to randomly perform leak detection on the spot.

However, the conventional leak detection method lacks accuracy and is a method of randomly exploring a wide area, and thus there is a problem in that the effectiveness is not guaranteed compared to the manpower and the cost to be input.

Therefore, in recent years, it has been divided into separate areas in the landfilled area, and separate monitoring devices have been installed in the designated areas, so that management is performed in each area. Monitoring control system is used.

A monitoring and control system for operating and managing a flow meter, a pressure gauge, a water quality, and other observation equipment is used in the water and sewage observation station system in accordance with the above, and the monitoring and control system senses a signal outputted from a flow meter, a pressure gauge, The measured data is recorded and stored in the logger memory at predetermined time intervals. Also, the stored data is generally transmitted through a leased line modem, an Internet modem, or a CDMA communication network according to a data transmission request from the supervisory control station or other set conditions.

In general, a water and wastewater control system is installed in more than one place, and a plurality of detection devices for detecting physical, chemical or biological factors such as water level, water temperature, pollution degree, pressure, flow rate, flow rate, carbon dioxide concentration, The remote control station is operated by using data transmitted from a plurality of remote control stations, which are installed in a physical or local environment, the manufacturer's product specification specificity of the manufacturer, or the sensing or transmission characteristics And various types of communication environment specifications are provided to control the water supply and sewerage by transmitting data to the monitoring control station in real time.

However, the surveillance and control system is operated and managed by the AC power source. However, the power consumption is large due to the characteristics of the system that collects and transmits data in real time, and the power consumption is continuously consumed even when data is not collected or transmitted There is a problem that efficiency is inferior in terms of economy.

For this purpose, a method has been proposed in which a power consumption mode is changed by switching to a power saving mode or a standby mode while using a solar panel while using the solar panel. However, a power supply problem due to damage of the solar panel, There is a problem that the problem of the operation error of the unit is not considered.

Accordingly, there is a need for a surveillance and control system capable of more efficiently and systematically monitoring and controlling as a surveillance system.

Brief Description of the Drawings The advantages and features of the present disclosure, and how to accomplish them, will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the present disclosure is not limited to the embodiments set forth herein, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, To fully explain the scope of the invention to a person skilled in the art, and this disclosure is only defined by the scope of the claims. Like numbers refer to like elements throughout.

In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present disclosure. The following terms are defined in consideration of the functions in the embodiments of the present disclosure, which may vary depending on the user, the intention or custom of the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

On the other hand, the remote terminal device of the present water / wastewater observation system is a remote terminal device of the water / wastewater observation system, which is disclosed in Korean Patent No. 10-1123819, filed on Apr. 14, 2010 and patented on Feb. 28, " Accordingly, the present invention will be described, illustrated and described together with the elements described in the above-mentioned document, the operations and effects thereof, and the improved reference numerals thereof.

1 is a block diagram showing a schematic configuration of a remote terminal apparatus of a water and wastewater observation system according to the present disclosure.

1, a remote terminal apparatus 100 of a water and wastewater observation system according to an embodiment of the present invention includes a data collection unit 110, a transmission control unit 120, a power control unit 130, a user interface unit 140, And a power source generating unit 150. [

The data collecting unit 110 collects and stores the data measured by the measurement sensor installed in the water supply and drainage system at a time interval corresponding to a predetermined collection period. Here, the measurement sensor includes a flow meter, a pressure sensor, and the like installed at each measurement point of the measurement flow path. When the analog input board (AICB) is mounted, the data collecting unit 110 receives analog signals of 4 to 20 mA, 0 to 1 V, and 0 to 5 V, When a digital input / output board is mounted, it can input / output a maximum 32-point digital contact signal. In addition, data can be collected by installing a wireless communication modem with an RS-232C port.

The collection period for the data collection unit 110 to receive and store data from the measurement sensor is set in advance and can be changed according to the setting of the user, and the settable collection period is 1 minute, 5 minutes, 10 minutes, 20 minutes , 30 minutes, 60 minutes, and the like.

Unlike a system that transmits data only under specific conditions, such as a flood warning system, a remote terminal device of a water and wastewater observation system needs to periodically check flow rate fluctuations, flow rates, and hydraulic pressure fluctuations. Therefore, the data of the measurement sensor is collected by the collection period set basically or the collection period set by the user. Of course, it is also possible to store the data every time a specific event occurs, that is, whenever the value of the measured data is out of a predetermined range, and may be stored at any time without setting the collection period by time.

If the memory space is insufficient by using a circular storage method, the data collection unit 110 automatically removes the oldest data sequentially and stores the newly collected data. Also, the data stored in the memory can be safely stored even if there is no power supply from the power control unit 130 due to the built-in backup battery.

The data stored in the data collection unit 110 may be transmitted to the monitoring control station by the transmission control unit 120. Alternatively, the user may directly connect a device such as a notebook computer and download necessary data from the data collection unit 110 .

The transmission control unit 120 transmits data stored in the data collecting unit 110 to an external monitoring control station through a communication network at a time interval corresponding to a preset transmission period, If not, it is transmitted to the supervisory control station at the time of data collection. Of course, the data can be transmitted in real time outside the period and the time specified by the user, and data can be converted into data, so that it can be used for the purpose of preliminary management of water quality improvement according to the flow rate or condition of the water supply and drainage. That is, it is possible to provide information related to water quality in consideration of pressure, PH, contamination, etc. of the water supply and drainage. In addition to the flow meter and pressure sensor described above, a temperature sensor, an electric conductivity sensor, a PH sensor, and the like may be additionally provided.

The transmission control unit 120 may use a CDMA communication module to transmit the stored data to the monitoring control station. That is, the transmission control unit 120 can perform data transmission with a CDMA modem installed in the TM server of the monitoring control station by using a CDMA modem provided separately. Data can also be transmitted to the supervisory control station via an auxiliary communication network using other VHF wireless modem or dedicated line modem (2W / 4W).

As described above, the transmission control unit 120 may transmit the data stored in the data collection unit 110 to the monitoring control station in accordance with a predetermined transmission period. This is because it is necessary to periodically observe the water supply and drainage system in the monitoring control station as well as to collect and store the data measured by the measurement sensor in the data collection unit 110 according to the collection period. However, in the event of an unexpected event, such as a leakage or a decrease in hydraulic pressure due to leakage, it is necessary to inform the supervisory control authority immediately.

Therefore, when the value of the data collected by the current data collecting unit 110 does not belong to the reference range set in advance, the transmission control unit 120 determines that the flow rate at a specific point in the water supply and drainage system is 80% The data is immediately transmitted to the monitoring control station at the time of data collection.

On the other hand, it is also possible for the transmission control unit 120 to transmit data by a data transmission request from the monitoring control station.

That is, when a data transmission request is received from the monitoring control station through the communication network between the transmission control unit 120 and the monitoring control station, the transmission control unit 120 transmits the data stored in the data collection unit 110 to the monitoring control station As shown in FIG. Further, when an abnormality occurs in the remote terminal apparatus 100 itself according to the present disclosure in addition to the case where an abnormality occurs in the value of data measured by the measurement sensor, for example, even when an abnormality occurs in the power supply, Together, it is possible to transmit a signal indicating an abnormal occurrence. At this time, if the CDMA network is in use, it can be transmitted through SMS (text message). Of course, it is possible to transmit data not only to the surveillance control station but also to the portable terminal of the user, and it is possible to transmit not only the time of the transmission request but also the data before the request and the real time data after the request time.

On the other hand, the transmission control unit 120 of the present disclosure includes a self-diagnosis unit 160 that determines whether or not there is an abnormality in the input and output signals to the control apparatus mounted therein. Through this, the input and output signals for the operation of the remote terminal apparatus 100 are checked to notify the user when an abnormal signal is detected. Accordingly, it is possible to know in advance the self-error due to the malfunction of the remote terminal apparatus 100 according to the present disclosure, and to prevent the error in the data transmission. Here, the reason why the self-diagnosis unit 160 in the present disclosure is located in the control unit 120 is that continuous power can be supplied to the control unit of the transmission control unit 120 through the power supply unit, The judgment of the self-diagnosis by the user can be continued without interruption. Of course, although the self-diagnosis unit 160 of the present disclosure is described and shown as being installed only in the transmission control unit 120, it is possible to install the self-diagnosis unit 160 at any place inside the remote terminal apparatus 100, It is obvious.

FIG. 7 is a schematic block diagram of self-diagnosis through a remote terminal device of a water / wastewater observation system according to an embodiment of the present disclosure. FIG. Fig.

7 and 8, an example in which each error situation or abnormal situation is distinguished and displayed to the user through the self diagnosis unit 160 of the present disclosure as described above will be described.

Here, the remote terminal of the present water / wastewater observation system includes a main control unit M for control, an input unit I for inputting a signal, an amplifier 4 for amplifying a signal input from the input unit I, An interface board 5 for distributing the amplified signal from the amplifier 4 to the speaker under the control of the main controller M and a speaker for reproducing the amplified signal from the amplifier 4, A main power supply unit 6 for supplying electric power and an emergency power supply unit 7 for supplying alternate power in case of a failure of the main power supply unit 6. [ Here, the remote terminal device of the present water / wastewater observation system does not refer to a speaker, but usually a configuration including light, sound, and vibration is generally used in relation to an abnormality of the device, so that a notification device such as a speaker It can be used.

In addition, a test point TP for detecting the presence or absence of input and output of signals transmitted to and from each component, a diagnostic apparatus interface 1 for collecting information sensed from each test point TP, A fault diagnosis module including a diagnostic apparatus control section 2 for inputting or outputting a signal and judging the information collected from the diagnostic apparatus interface 1 to perform a fault diagnosis.

7, each of the components includes an input unit I, a main control unit M, an amplifier 4, an interface board 5, and a speaker. The test points TP-a , TP-a ', TP-b, TP-b', TP-c, TP-c 'and TP-d.

The test points TP-a, TP-a, TP-b, TP-c, TP-c and TP-d installed as shown in FIG. 7 are connected to the diagnostic device interface 1 And this diagnostic device interface 1 is connected to the information transmitted from each test point TP-a, TP-a ', TP-b, TP-b', TP-c, TP- And transfers it to the diagnostic device control unit 2. [ Here, although the diagnostic apparatus interface 1 is described as a separate component, this is for clarity of description, and it is obvious to those skilled in the art that the user interface unit 140 of the present disclosure is a person skilled in the art in carrying out the functions described above. Here, it goes without saying that the diagnostic apparatus interface 1 can be used together with the user interface 140 as a separate configuration.

The diagnostic device control unit 2 then outputs information transmitted from each of the test points TP-a, TP-a ', TP-b, TP-b', TP-c, TP-c 'and TP- 8 and the fault diagnosis is performed.

8, the fault diagnosis procedure includes a step (A) of checking the abnormality of the apparatus, a test step (TP-a), a TP-a ' (B) detecting a signal unrecognized part of the non-sensing part TP-c ', TP-d, TP-d' (D) judging an abnormal part between the test point (TP) in which the signal has been confirmed and the test point (TP) in the signal undetected part, a step (C) The process proceeds to the step (E) of reporting the undetected test point TP.

(F) inputting the check signal (a) to the test point (TP) having the earliest signal arrival order in the diagnostic device control unit (2) if a large number of signal undetected test points (TP) , And step (G) of confirming whether or not the check signal (a) of the remaining test points (TP) is input is added to step (D) of judging the abnormal part.

7, if the signal undetected portion is a test point TP-c, the signal arrival order is the input signal of the input portion I, the main control portion M, the amplifier 4, The presence or absence of the signal input of the adjacent test point TP-b 'having a signal arrival order that is earlier than the test point TP-c is confirmed.

If the signal of the test point TP-b 'is normally inputted, since the input signal is lost in the amplifier 4, the faulty portion becomes the amplifier 4, And transmits the result to the administrator via SMS or VMS via the transmission unit 3 and displays it on the diagnostic device interface 1 which is a diagnostic result display device.

If the signal undetected portion is the test point TP-b ', the signal arrival order is the order of the input portion I, the main control portion M, the amplifier 4, the interface board 5, (TP-b ') having a higher signal arrival order than that of the adjacent test point (TP-b').

If the signal of the test point TP-b is normally input, since the input signal is lost in the wire connecting the test point TP-b 'and the test point TP-b, B 'and the test point TP-b, and reports the test point TP-b' together with the undetected test point TP-b 'in the diagnostic device control unit 2, To the diagnostic device interface 1, which is a diagnostic result display device.

If the signal undetected test point TP detects a plurality of signals TP-b, TP-b ', TP-c and TP-c' in one signal line, The check signal a is inputted to the fastest test point TP-b and the check signal a of the remaining test points TP-b ', TP-c and TP-c' is inputted .

That is, if the check signal a of the remaining test points TP-b ', TP-c and TP-c' is normally detected, it is determined that the rest of the test points TP- And sends it to the administrator via SMS or VMS via the transmission unit 3 and displays it on the diagnostic device interface 1 which is a diagnostic result display device. The action and method of distinguishing each error situation or an abnormal situation through the self diagnosis unit 160 as described above is one example for explaining the present disclosure more easily and clearly, It is obvious to those skilled in the art that the present invention is not limited thereto.

The power control unit 130 is connected to an external solar cell module, a storage battery, and an AC power unit to supply power to the data collecting unit 110 and the transmission control unit 120. The data collecting unit 110 and the transmission control unit 120 The power supply is cut off and the power supply is supplied to the data collecting unit 110 only for a time when the data collecting unit 110 collects data from the measurement sensor.
