Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, an overview of a water and sewage treatment plant management system having an operation overview management device according to the present embodiment will be described.
FIG. 1 is a conceptual diagram showing a water and sewage treatment plant management system according to this embodiment.
For example, the consignor is the owner or manager of the water and sewage treatment plant, and grasps the operation overview of the water and sewage treatment plant by browsing the operation overview information provided from the operation overview management device. In addition, information is stored in the schedule table storage unit and bulletin board device of the operation overview management device. The subcontractor who is a management contractor inspects each facility and each device at the site of the water and sewage treatment plant, and stores the inspection information in the detailed information storage device. Then, the operation overview management device extracts the inspection information stored in the detailed information storage device, generates operation overview information that simply summarizes the operation information of the water and sewage treatment plant, and the contractor views this operation overview information To check the driving status.

Next, a configuration example of the water and sewage treatment plant management system according to the present embodiment will be described.
FIG. 2 is a block diagram showing the configuration of the water and sewage treatment plant management system according to this embodiment.
In the water treatment plant management system according to the present embodiment, for example, a browser terminal 100 on which a consignor browses operation summary information of a water and sewage treatment plant, and details of inspection actual values of each facility of the water and sewage treatment plant are stored. Information storage device 200, operation overview management device 300 that generates operation overview information based on the actual inspection value and the input value from facility field terminal 400, and the facility for inputting the actual inspection value at the site of the water and sewage treatment plant Field terminal 400. Each terminal or device is connected by an electric communication line such as a local area network (LAN) or a wide area network (WAN), and can communicate information with each other.
The browser terminal 100 is an information terminal used by a consignor. In this embodiment, a so-called PC (Personal Computer) including a control unit, a display unit, and an input unit is applicable, but information communication is possible. As long as the information terminal has a display unit, the information terminal may not be a PC. For example, the browser terminal 100 displays the driving overview information received from the driving overview management apparatus 300 on the display unit.

  The detailed information storage device 200 stores inspection items and actual inspection values in association with facility identification information for identifying facilities and device identification information for identifying devices included in the facilities. The facility identification information is information that uniquely identifies the facility provided in the water and sewage treatment plant, and may be, for example, a facility name or numerical numerical information of a serial number. The device identification information is device identification information included in the facility indicated by the facility identification information. For example, the device identification information may be a device name, or may be information in which the numerical information of the serial number is added to the end of the numerical information of the facility identification information. Here, the equipment identification information and the equipment identification information have a one-to-N (N> 0) relationship. For example, if the facility is a water intake facility, device identification information of devices such as an electric motor, a water intake pump, and a water intake is associated. Here, the facility may be composed of a single device.

The operation overview management apparatus 300 includes an operation overview distribution unit 310, a determination unit 320, a determination reference value correction unit 330, a determination reference value correction availability determination unit 340, an inspection value extraction unit 350, an input unit 360, and a storage. Part 370.
The operation overview distribution unit 310 generates overview information of the entire facility based on the result of the facility abnormality determination process described later, and transmits the overview information to the viewer terminal 100.
The determination unit 320 determines whether there is an equipment abnormality from the manually input equipment information, the inspection result value information, and the judgment reference value.

When the actual inspection value exceeds the determination reference value, the determination reference value correction availability determination unit 340 determines whether or not to change the determination reference value according to external factors such as season and failure history and internal factors.
The determination reference value correction unit 330 changes the determination reference value when the determination reference value correction availability determination unit 340 determines to change the determination reference value.
The inspection value extraction unit 350 acquires inspection result values, facility information, and the like from the detailed information storage device 200.
The input unit 360 receives information input such as text input from the facility floor terminal 400 or the like.

  The storage unit 370 stores information necessary for distributing the driving overview information, and includes a determination reference value storage unit 371, a first rule storage unit 372, a second rule storage unit 373, and a third rule. Storage unit 374, fourth rule storage unit 375, fifth rule storage unit 376, sixth rule storage unit 377, driving summary storage unit 378, schedule table storage unit 379, and bulletin board storage unit 380 A device information storage unit 381, a failure information storage unit 382, and a manual input facility information storage unit 382.

  The determination reference value storage unit 371 stores the upper and lower limit determination reference values and the increase / decrease rate of the determination reference value corresponding to the inspection item. FIG. 9 is a diagram illustrating a configuration of determination criterion information stored in the determination criterion value storage unit according to the present embodiment. This criterion information is associated with the device identification information for identifying the device, the inspection item, changeability, application rule, change value, upper limit (HH), upper limit (H), and lower limit (L). And a lower limit (LL) and whether or not the reference value can be restored are stored.

  The check item is an item for checking the device indicated by the device identification information. For example, if the device is a sewage pump, the check item includes a current value, a voltage value, a flow rate, a rotation speed, and the like. The changeability is information indicating whether or not the determination reference value is corrected when the actually measured inspection value exceeds the determination reference value. The application rule is information for identifying a correction determination rule to be applied when determining whether or not to change the determination reference value. For example, in the present embodiment, the first to sixth rule storage units are provided. The number is memorized. The change value is information on the degree to which the determination reference value is changed, and is expressed in percent (%) notation here. When the determination reference value correction unit 330 changes the determination reference value, the percentage stored as the change value is increased or decreased.

  The upper limit (HH) is information indicating the changed upper limit value when the determination reference value is changed. Even when the determination reference value correction availability determination unit 340 determines to change the determination reference value, the value indicated as the upper limit (H) cannot exceed the upper limit (HH). The upper limit (H) is information indicating an upper limit value as a determination reference value. When the actual inspection value exceeds the value indicated by the upper limit (H), the determination unit 320 determines that the inspection is abnormal. The lower limit (L) is information indicating a lower limit value as a determination reference value. When the actual inspection value exceeds the value indicated by the lower limit (L), the determination unit 320 determines that the inspection is abnormal. The lower limit (LL) is information indicating the lower limit value after the change when the determination reference value is changed. Even when the determination reference value correction availability determination unit 340 determines to change the determination reference value, the value indicated as the lower limit (L) cannot exceed the lower limit (LL). Whether or not the reference value can be restored is information indicating whether or not to restore the determination reference value changed by the correction. For example, if information indicating whether or not the reference value can be restored is stored, the determination reference value correcting unit 330 may For example, the determination reference value may be periodically restored to the value before correction once a quarter.

  In the first to sixth rule storage units, determination reference value correction rules corresponding to the application rules are stored. In this embodiment, the first to sixth types of rules are stored in advance, but the number of rules may be one or seven or more. Each of them stores a correction value in association with a predetermined value, and the larger the correction value, the higher the possibility of change. That is, if the correction value is high, the determination reference value is changed. These rules are quantified rules based on know-how of operation of water and sewage treatment plants.

  The first rule storage unit 372 stores in advance correction rules determined based on the processing month. FIG. 3 is a diagram illustrating a configuration of the first rule stored in the first rule storage unit according to the present embodiment. In the first rule storage unit 372, for example, correction values are stored in association with month information (1 to 12). In the example shown in FIG. 3, when the month is “1”, “2”, “12”, the correction value is “1.5”, and the months are “3”, “4”, “5”, “6”. ”,“ 10 ”,“ 11 ”, the correction value is“ 1 ”, and the month is“ 7 ”,“ 8 ”,“ 9 ”, the correction value is“ 0.5 ”. . In other words, the temperature is low in winter and the organic content in sewage is high, and generally the sewage concentration is high, so the correction value is set high (the possibility of change is increased), while the sewage concentration is low in summer. The correction value is set low.

  In the second rule storage unit 373, correction rules determined based on the weather are stored in advance. FIG. 4 is a diagram illustrating the configuration of the second rule stored in the second rule storage unit according to the present embodiment. In the second rule storage unit 373, for example, correction values are stored in association with weather information (sunny, cloudy, rainy, snowy). In the example shown in FIG. 4, the correction value when the weather is “rain” and “snow” is “1.5”, the correction value when the weather is “cloudy” is “1”, and the weather is “ The correction value for “sunny” is “0.5”.

  The third rule storage unit 374 stores in advance correction rules determined based on the device importance. FIG. 5 is a diagram illustrating a configuration of the third rule stored in the third rule storage unit according to the present embodiment. In the third rule storage unit 374, for example, correction values are stored in association with device importance levels (A, B, and C, where A is the highest importance level and C is the lowest). In the example shown in FIG. 5, the correction value when the device importance is “C” is “1.5”, and the correction value when the device importance is “B” is “1”. The correction value when “A” is “A” is “0.5”. That is, if the equipment importance is high, when the actual inspection value exceeds the judgment reference value, the equipment abnormality judgment is made without correcting the judgment standard value, so the equipment abnormality is reported immediately.

  In the fourth rule storage unit 375, correction rules determined based on the number of inspection abnormal cases are stored in advance. FIG. 6 is a diagram illustrating a configuration of the fourth rule stored in the fourth rule storage unit according to the present embodiment. In the fourth rule storage unit 375, for example, correction values are stored in association with threshold values (0, 2, 4, 6, 8, 10) for the number of inspection abnormalities. In the example illustrated in FIG. 6, the device importance is “2.5” when the device importance is “10”, and the device importance is “2” when the device importance is “8”. When the value is “6”, the correction value is “1.5”, when the device importance is “4”, the correction value is “1”, and when the device importance is “2” Is “0.5” and the correction value when the device importance is “0” is “0”.

  In the fifth rule storage unit 376, correction rules determined based on the failure importance are stored in advance. FIG. 7 is a diagram illustrating the configuration of the fifth rule stored in the fifth rule storage unit according to the present embodiment. In the fifth rule storage unit 376, for example, correction values are stored in association with failure importance (major failure, minor failure, none). In the example shown in FIG. 7, the correction value when the failure importance is “None” is “1.5”, and the correction value when the failure importance is “Minor failure” is “1”. The correction value when the degree is “serious failure” is “0.5”.

  The sixth rule storage unit 377 stores in advance correction rules determined based on rainfall. FIG. 8 is a diagram illustrating a configuration of the sixth rule stored in the sixth rule storage unit according to the present embodiment. In the sixth rule storage unit 377, for example, correction values are stored in association with the rainfall (0 mm, 20 mm, 40 mm, 60 mm, 100 mm). In the example illustrated in FIG. 8, the correction value when the rainfall is “20 mm” is “1”, the correction value when the rain is “40 mm” is “0.5”, and the rainfall is “0 mm” and “60 mm”. The correction value for “100 mm” is “0”. That is, the correction value is high if it rains, but when the rain amount is larger than a certain amount (60 mm in this example), it is considered to be sudden rain, so the correction value is low.

The operation overview storage unit 378 stores operation overview information in association with the facility identification information.
In the schedule table storage unit 379, a schedule related to the equipment, such as when evacuation drills are performed, is stored. The bulletin board storage unit 380 stores information for the electronic bulletin board related to the facility and the operation of the facility.

  The device information storage unit 381 stores, for example, one piece of device information for each device. The device information storage unit 381 is associated with facility identification information for identifying a facility and device identification information for identifying a device included in the facility. The important device flag information indicating whether or not is an important device is stored. The equipment identification information is information that uniquely identifies equipment provided in the water and sewage treatment plant, and is, for example, numerical information of serial numbers. The device identification information is device identification information included in the facility indicated by the facility identification information. For example, the device identification information is information in which the numerical information of the serial number is added to the end of the numerical information of the facility identification information. Here, the equipment identification information and the equipment identification information have a one-to-many relationship. For example, if the facility is a water intake facility, device identification information of devices such as an electric motor, a water intake pump, and a water intake is associated. As the important device flag, for example, 1 is stored if the device is an important device, and 0 is stored if the device is not an important device.

  In the manual input equipment information storage unit 382, for example, inspection status text information input by a person in charge of equipment in association with equipment identification information for identifying equipment, equipment abnormality flag indicating whether or not there is an abnormality, and failure Is stored with information on a major failure flag indicating whether or not a major failure. The equipment identification information is information that uniquely identifies equipment provided in the water and sewage treatment plant, and is, for example, numerical information of serial numbers. The inspection situation text information is text information that the equipment person in charge freely inputs from the input unit of the equipment field terminal 400. For example, when the equipment person in charge finds a failure, “pump blockage”, “bearing heat generation” The failure discovery date and time, the person who found the failure, the detailed failure status, etc. are entered. Alternatively, the person in charge of the facility may input the contents of the special mention item, although it is not a failure. As the equipment abnormality flag, for example, 1 is input when a failure state is input to the inspection state text information, and 0 is input when there is no failure. For example, when 1 is input to the equipment abnormality flag, 1 is input if the failure is a major failure, and 0 is input if the failure is a minor failure.

Each piece of information stored in the manually input equipment information storage unit 382 may be input by the person in charge of the equipment using the equipment field terminal 400, or the person in charge of the equipment inputs only the inspection status text information corresponding to the equipment identification information. After that, the person in charge of the equipment refers to the entered inspection status text information to determine whether or not the equipment is abnormal and whether or not it is a serious failure. It is good also as the management which inputs the information with the equipment field terminal 400.
The facility field terminal 400 is an information terminal used by a facility person who is a subcontractor at the site of a water and sewage treatment plant, and may be a so-called PC or a PDA (Personal Digital Assistant).

Next, an operation example of the water and sewage treatment plant management system according to the present embodiment will be described.
<Information input>
The subcontractor inspects each device provided in each facility of the water and sewage treatment plant using predetermined inspection items and inspection methods. For example, an equipment person in charge carries the equipment field terminal 400 such as a PDA, and stores in the equipment field terminal 400 inspection actual values obtained by inspecting values such as the current value, voltage value, flow rate, and rotation speed of each device. The facility floor terminal 400 transmits the stored actual inspection value to the detailed information storage device 200 for storage. Moreover, the input part 360 receives the input of an inspection actual value from the screen which can browse and input the detailed information of a driving | running overview.

  In addition to the actual inspection value information that is numerical information acquired by a meter or the like, the facility field terminal 400 receives text information for each facility that is input from the person in charge of the facility via the input unit 360 of the operation overview management device 300. May be input to the manual input facility information storage unit 382. Text information is information about the equipment, such as "weeding work around the management building", "painting the wall surface of the electrical building", "was floor wax on the central building", etc. Information that is not directly linked may be used. Alternatively, the text information may be information on periodic work such as “cleaning work was performed on AA equipment” or “oil was regularly exchanged on BB equipment”. The input unit 360 is associated with the equipment identification information, and includes a text input field for overview information, a text input field for communication items, a check box for inputting the presence / absence of equipment abnormality, and, if abnormal, the failure is indicated. And a check box for inputting whether or not there is a serious failure.

<Equipment abnormality judgment processing>
FIG. 10 is an activity diagram showing an operation example of equipment abnormality determination processing according to the present embodiment.
The operation overview management apparatus 300 performs an equipment abnormality determination process for each equipment identification information. First, the determination unit 320 performs a failure determination process on the manually input facility information read from the manually input facility information storage unit 382 (step S1000). Then, the determination unit 320 reads from the device information storage unit 381 all device information corresponding to the equipment identification information that has undergone the failure determination process. Then, the determination unit 320 performs device abnormality determination processing for all the read device information (step S1100). FIG. 14 is a diagram illustrating items used in the device abnormality determination process according to the present embodiment. Then, the determination unit 320 refers to the results of the failure determination process and the device abnormality determination process (step S1200), and the failure determination process outputs that there is a failure, or the device abnormality determination process causes a device abnormality. If the output is “Yes”, it is determined that there is an equipment abnormality (step S1300). On the other hand, if an output indicating no failure is output in the failure determination process and an output indicating no apparatus abnormality is output in the device abnormality determination process, it is determined that there is no equipment abnormality (step S1400).

<Failure judgment processing>
Hereinafter, the failure determination process in step S1000 in FIG. 10 will be described in detail.
FIG. 11 is an activity diagram showing an operation example of failure determination processing according to the present embodiment.
The determination unit 320 reads the manually input facility information stored in the manually input facility information storage unit 382. And the determination part 320 will determine with it being a failure, if an equipment abnormality flag is 1 among manual input equipment information, and if an equipment abnormality flag is 0, it will determine with it not being a failure (step S1001). If the determination unit 320 determines that there is no failure, the determination result that there is no failure is output (step S1005).

On the other hand, if the determination unit 320 determines that there is a failure, the important device flag corresponding to the facility identification information is read from the device information storage unit 381 (step S1002). If the important device flag is 1, the determination unit 320 outputs a determination result that there is a failure (step S1004). If the important device flag is 0, the determination unit 320 refers to the major failure flag in the manually input facility information (step S1003). If the major failure flag is 1, the determination unit 320 outputs a determination result that there is a failure. On the other hand, if the major failure flag is 0, the determination unit 320 outputs a determination result that there is no failure.
In this way, even if there is a failure in the device, if the device is not an important device and the failure is a minor failure, the degree of influence and fatality on the entire facility is low. Therefore, it can be determined that it is not necessary to report a failure to the consignor as the operation overview information.

<Device abnormality determination processing>
Hereinafter, the device abnormality determination process in step S1100 in FIG. 10 will be described in detail. FIG. 12 is an activity diagram showing an operation example of device abnormality determination processing according to the present embodiment. FIG. 13 is a conceptual diagram showing an operation example of device abnormality determination processing according to the present embodiment. FIG. 13 shows an operation concept when the target device for device abnormality determination processing is a sewage pump.

First, the inspection value extraction unit 350 acquires, from the detailed information storage device 200, inspection actual measurement value information corresponding to the facility identification information for which the failure determination process has been performed in step S1000. For example, in the example of the sewage pump, the inspection value extraction unit 350 has an inspection actual value 58 (A) in which the inspection item is a current value, 430 (V) as an inspection actual value in which the inspection item is a voltage value, and an inspection item. The actual inspection value information is acquired from the detailed information storage device 200 as 230 (m ³ / h) as the actual inspection value with the flow rate value and 940 (prm) as the actual inspection value with the inspection item being the rotation speed.

  The determination unit 320 compares the determination reference value read from the determination reference value storage unit 371 for each inspection item (step S1101). For example, in the example of the sewage pump, as compared with the example shown in FIG. 9, first, the actual inspection value (58 (A)) of the current value has an upper limit (HH) of 65 and a lower limit (LL) of 50. Because there is, it does not exceed the criterion value. The determination unit 320 determines that there is no inspection value abnormality (step S1105). Also, the determination unit 320 completes the device abnormality determination process in which the inspection item is a current value, assuming that there is no device abnormality (step S1108).

  The determination unit 320 performs the device abnormality determination process for the voltage value and the flow rate value in the same manner as the device abnormality determination process for the current value. In the example of this embodiment, neither the voltage value nor the flow rate value exceeds the determination reference value shown in FIG. And the determination part 320 performs the apparatus abnormality determination process of the check actual value (940 (prm)) of rotation speed. The determination reference value of the rotation speed of the sewage pump shown in FIG. 9 has an upper limit (H) of 900, and the actual inspection value exceeds the determination reference value. A correction propriety determination process is performed (step S1102).

  The determination reference value correction availability determination unit 340 refers to the application rule associated with the rotational speed of the sewage pump in the determination reference information stored in the determination reference value storage unit 371. From the example illustrated in FIG. 9, since the corresponding application rule is “12345”, the determination reference value correction availability determination unit 340 includes the first rule storage unit 372, the second rule storage unit 373, and the third rule storage. The correction value is detected based on the respective rules stored in the unit 374, the fourth rule storage unit 375, and the fifth rule storage unit 376, and the sum of the correction values is calculated as the correction possibility determination value. .

  In the present embodiment, for example, if the processing month is January, the weather is rain, the equipment importance of the sewage pump is B, the number of past inspection abnormalities is 5, and the failure importance is a minor failure, The correction value by the rule is 1.5, the correction value by the second rule is 1.5, the correction value by the third rule is 1, the correction value by the fourth rule is 1, and the correction value by the fifth rule is 1 Therefore, the correction possibility determination value which is the sum of the correction values is 6. As described above, the determination reference value correction availability determination unit 340 outputs “Yes” as the determination reference correction availability determination result if the correction availability determination value exceeds the number of applied rules. On the other hand, if the correction propriety determination value does not exceed the number of applied rules, the determination reference value correction propriety determination unit 340 outputs “No” as the determination reference correction propriety determination result.

  If the determination criterion correction availability determination result is acceptable, the determination criterion value correction unit 330 corrects the determination criterion value stored in the determination criterion value storage unit 371 (step S1103). For example, the determination reference value information of the determination reference value storage unit 371 is read out, in which the device is a sewage pump and the inspection item is the rotation speed. As shown in FIG. 9, since the change value of the determination criterion information is 5%, the determination criterion value correction unit 330 is the upper limit (H) of the determination criterion information stored in the determination criterion value storage unit 371. The value of 900 is updated and stored in 945 which is a value increased by 5%.

  When the determination reference value correction unit 330 updates the determination reference value, the determination unit 320 compares the actual inspection value with the determination reference value using the determination reference value corrected in step S1103 (step S1104). Since the actual inspection value (940 (prm)) of the rotational speed does not exceed the corrected determination reference value (945), the determination unit 320 determines that the rotational speed has no inspection value abnormality (step S1105). On the other hand, if the inspection actual value exceeds the corrected determination reference value, the determination unit 320 determines that there is an abnormality in the inspection value (step S1106).

  When the determination unit 320 determines that the actual inspection value is abnormal, the determination unit 320 reads the important device flag corresponding to the device identification information corresponding to the actual inspection value information from the device information storage unit 381. . If the read important device flag is 0, the determination unit 320 outputs a determination result that there is no device abnormality. On the other hand, if the read important device flag is 1, the determination unit 320 outputs a determination result that there is a device abnormality (step S1109).

<Distribution of driving status information>
When the determination unit 320 performs the equipment abnormality determination process for all the inspection actual measurement value information stored in the detailed information storage device 200, the operation overview distribution unit 310 collects the equipment abnormality determination process results. That is, for each piece of equipment identification information, the driving outline distribution unit 310 generates driving outline information in which the determination of whether there is an equipment abnormality or whether there is an equipment abnormality is associated with the equipment abnormality flag, and stores the operation outline information in the driving outline storage unit 378. The driving overview distribution unit 310 may distribute the driving overview information to the browser terminal 100, or may distribute it in response to the driving overview information request from the browser terminal 100.

The browser terminal 100 may be provided with a browsing application that displays driving summary information, and the driving summary information may be browsed from the browser terminal 100. FIG. 15 is a diagram illustrating an example of an operation overview providing screen according to the present embodiment.
Further, the operation overview distribution unit 310 may output the operation overview information in a spreadsheet file format. If such a spreadsheet file is generated, for example, driving summary information can be saved on a notebook PC or a memory stick and carried around, and access from the browser terminal 100 to the driving summary management device 300 can be performed with a specific LAN. Even if it is limited within the network, it can be sent by e-mail or the like. FIG. 16 is a diagram illustrating an example of browsing the operation summary detailed information output according to the present embodiment.

  Further, the determination reference value correction unit 330 may perform a process of returning the determination reference value corrected and changed every predetermined period, for example, every quarter. For example, the determination reference value correction unit 330 stores the initial value (default value) of each determination reference value in advance, and refers to the timer function provided in the operation overview management device 300 to determine the determination reference value every quarter. The determination reference value of the determination reference value information stored in the storage unit 371 where the reference value restoration is possible is updated to the initial value.

As explained above, according to the present invention, even if the consignor who has entrusted the management of the water and sewage treatment plant to the subcontractor does not have specialized knowledge regarding the operation of the water and sewage treatment plant, there is an equipment abnormality. Whether or not there is can be grasped.
Furthermore, even when there is a system that is already operating using information such as the actual inspection value information stored in the detailed information storage device 200, the operation overview management device 300 extracts information from the detailed information storage device 200. Since the operation overview information is provided to the browser terminal 100 by processing the operation overview information, it is possible to generate the operation overview information without affecting the existing system.

  In addition, the program for realizing the function of the processing unit in the present invention is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into the computer system and executed, thereby executing the operation overview information. Distribution may be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer system” includes a WWW system having a homepage providing environment (or display environment). The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
