An upper engine of the lower integrated supervisory control unit 2 may be, for example, a waterworks establishment belonging to a local government, and a water resources corporation belonging to a government agency may be another upper engine.

In the present invention, in the implementation of the lower device integrated detection and transmission control device, the lower integrated supervisory control unit 2 is a measured value or controller in the lower device, i.e., the flow meter 10, the turbidimeter 8, etc. The detection value of the lower device, that is, the temperature sensor 14 or the pressure sensor 16, etc. dependent on the display unit 4 of the field control panel terminal A is immediately displayed and reported to the upper engine.

More importantly, the lower integrated supervisory control unit 2 of the present invention scans each lower device 30 at the time of new installation or replacement installation of the lower device 30 related to water and sewage water treatment so that the data is automatically recognized and reported to the upper part. Of course, even in a power reset situation due to power outages, communication failures, lightning accidents, etc., the data of the lower device 30 can be automatically recognized, and the data can be displayed as well as reported to the upper authority.

Unlike general-purpose computers, it is virtually difficult to recognize the sub-devices 30 with different companies, product names, different protocols and different data structures in the site control panel for remote management of water supply and sewage without a unified operating system. While performing installation and maintenance with the help of a computer, in the present invention, the lower integrated supervisory control unit 2 is implemented to perform this by automatic scanning.

To this end, it includes a memory unit 20 which is operated under the control of the lower integrated supervisory control unit 2, the memory unit 20, as shown in Figure 1, a scan protocol pool (scan protocol pool) 22, A conversion table 22, a standard protocol storage 26, and a valid data range value storage 28.

The memory unit 20 is related to the water and sewage water treatment installed in the field control panel and scans various lower devices 30 which may have different protocols and different data structures to automatically recognize and report them to one or more upper organs. Save the data.

In more detail, the memory unit 20,

A conversion table 24 for converting data obtained by accessing the lower device 30 through the scan into a standard protocol defined in the standard protocol storage 26;

A standard protocol storage unit 26 having a standard protocol defined in a format capable of reporting data of various types of lower devices 30 to upper organizations,

And a valid data range value storage unit 28 for storing a valid data range value to determine whether data read from the lower device 30 is normal.

In FIG. 1, the display unit 4 displays the data (measured value or detected value, etc.) transmitted from the lower device 30, data conforming to a standard protocol, display data for performing a user interface, and the like. Displayed under the control of, the up, down, left and right covertons of the input unit 6 may be utilized when adjusting and setting the scale value according to the type of device when the lower device 30 is a lower device such as a sensor without a processor.

2 is a control flowchart of the lower integrated supervisory control unit 2 of FIG. 1 according to an exemplary embodiment of the present invention.

1 and 2, the operation according to the embodiment of the present invention will be described in more detail.

Various sub-devices 30 related to water and sewage water treatment installed in field control panels have almost different protocols and different data structures.

For example, the flow meter 10 of the lower device 30 may be of various types such as ultrasonic type, electronic type, pad type, gear type, venturi type, etc., and the data coding type is ASCII, bit ( bit) data, hex values, word methods, and so on, and protocols are also different.

Even if the lower devices 30 have different protocols and data structures as described above, the lower integrated supervisory control unit 2 according to the present invention is configured to reset the power or change the port of the lower device 30 due to a power failure, communication failure, or lightning accident. When there is either a connection or a connection to the new subordinate device 30, a number of scan protocols in the scan protocol pool of the memory unit 20 are assigned to the subordinate devices 30 which may have different protocols and different data structures. Try to access them one by one to recognize the data, convert it to a standard protocol, and report it to the top.

More specifically, the lower integrated monitoring control unit 2 determines in step 100 to 102 of FIG. 2 whether there is a power reset, a lower device change connection, or a new lower device connection due to a power failure, a communication failure, a lightning accident, or the like. .

If there is a power reset, a sub-device change connection, or a new sub-device connection, the lower integrated supervisory control unit 2 performs step 104 of FIG. 2 first before attempting to access the lower device 30 automatically. It is determined whether the lower device 30 is a lower device without its own processor.

If the lower device 30 does not have its own processor, such as the temperature sensor 14 or the pressure sensor 16, the user interface using the up, down, left, and right buttons of the display unit 4 and the input unit 6 shown in FIG. Scale detection range.

For example, there is a PT sensor and a CA sensor in the type of the temperature sensor 14, which is one of the lower devices 30, and the PT sensor is scaled on the display unit 4 at 0 to 200 ° C and the CA sensor is 0 to 100. The scale is displayed on the display unit 4 at ° C. Therefore, the operator sees the sensor type and performs scaling through the user interface using the up, down, left, right, and right key buttons of the input unit 6 so that the detection range is scaled to 0 to 200 ° C.

When the detection range is scaled by performing step 108 of FIG. 2 or when it is determined as the lower device 30 having its own processor such as the flow meter 10 in step 104 of FIG. 2, the lower integrated supervisory control unit 2 is shown in FIG. 2. In step 106 of step S, an access to the lower device 30 is sequentially performed using one scan protocol from the scan protocol pool 22 of the memory unit 20 according to a predetermined routine.

That is, the present invention attempts to automatically connect to the lower device 30 without a separate communication program.

It is determined whether there is a data response according to the access attempt in step 110 of FIG. An access attempt is made (it repeats steps 106, 110, 112, and 106 of FIG. 2).

If there is no data response even though the user attempts to access the last scan protocol, the lower integrated supervisory control unit 2 stops access to the lower device as shown in step 114 of FIG. Is displayed on the display unit 4.

On the other hand, if the data response according to the access attempt is immediately in step 110 of FIG. 2, the lower integrated monitoring control unit 2 displays the data read from the lower device 30 on the display unit 4 and at the same time whether the read data is valid. Is compared with the valid data range value stored in the valid data range value storage unit 28 of the memory unit 20.

For example, address D1 corresponds to an instantaneous value (data), address D2 corresponds to an integrated value (data), and address D3 must be in a valid data range indicating whether there is an error (data). If the integrated value corresponding to the address D2 has been read and the value related to the presence or absence of an error other than the integrated value range is determined as not valid data.

Thus, if the data that has been answered is not in the valid data range, the lower integrated monitoring control unit 2 displays the abnormal data through the display unit 4 in step 122 of FIG. 2 so that an operator can take action.

If the data returned in the determination of step 118 of FIG. 2 falls within the valid data range, the lower integrated monitoring control unit 2 proceeds to step 120 of FIG. 2 and waits for a few seconds while displaying the read data on the display unit 4. This gives the operator the ability to check and take additional action and automatically sets up the data as normal data when there is no action input. That is, in the present invention, the automatic display of data according to the lower device 30 is performed and automatic setting is performed.

The lower integrated supervisory control unit 2 then sets up the set data according to the standard protocol format using the conversion table 24 of the memory unit 20 (step 124 of FIG. 2), and displays it on the display unit 4. At the same time, it is stored in the memory unit 20 (step 126 of FIG. 2). That is, the automatic address allocation function according to the lower model is performed.

In this way, when the data read from the lower device 30 is stored in the arrangement and memory unit 20 in accordance with the standard protocol, the lower integrated supervisory control unit 2, as shown in step 128 of FIG. The data of the lower device 30 (including the error data) is transmitted to an institution (waterworks establishment or water resources corporation, etc.) in a standard protocol format.

As described above, in the present invention, when the lower integrated supervisory control unit 2 is installed in the field control panel, when a new installation or replacement installation of the water supply and sewage-related lower device 30 occurs in a power reset situation due to a lightning strike or the like, different types and different formats are provided. Even if the lower device 30 of the data can be recognized as an automatic scan, of course, it can be converted to a standard protocol format and transmitted to the upper organ.

In the upper engine, it is possible to comprehensively monitor various types of lower devices 30 through only one transmission line.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of claims and equivalents thereof.
