Abstract

PURPOSE:To reduce message printing articles and simplify the message investigation or the like by restraining the message print according to the conditional change of a monitored system relative to the operational output through the apparatus main body, and by storing the conditional change of the monitored system in background data thereby displaying and reprinting it thereafter. CONSTITUTION:By an operational output part 10 respectively connected to an automatic controlling operational unit 20 and an operator operating demand unit 30, a controlled system 1 is operated. At this time, an operational mask bit set S5 is carried out to the operational mask status 60, and the conditional change of the controlled system 1 is detected by a conditional change detector 40. Also, by a message edition processing unit 50, restraining check S6 is conducted for the operational output mask status 60, and during the setting period, message demand output S4 is not performed. Further, irrespective of set/reset of the operational output mask status 60, the conditional change is stored in background data 70. Then, the background data 70 is displayed at the displaying unit 3 by a background data displaying unit 80 and subsequently reprinted by a printer 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a supervisory control device having a message printing function, which can save energy by reducing message printing paper and can extend the life of the printer. Regarding the device.

[0002]

2. Description of the Related Art When a monitoring control device changes the state of a device to be monitored, the information is printed as a message on a printer. This makes the message complicated. If the printer is unable to print due to paper shortage, etc., the information in the meantime is lost.

In the message printing function in the conventional monitor and control apparatus, the operation output section operates according to the output request from the automatic control operation section and the operator operation request section,
This output causes the control target (monitoring target) to operate in response to the request and a state change occurs, and the input change request is detected by the state change detection unit. Information is passed to the message edit processing unit as a message request, and the print unit is notified. To make a print request,
The printing section prints the message.

As can be seen from this, if the print portion is abnormal due to the print request, the data is erased.

[0005]

In the conventional message printing configuration, the message printing paper is wasted because the printer prints each time the system status changes. Furthermore, when an abnormality occurs, messages become complicated even when investigating the operating status of the system, and it takes time to analyze the abnormality. Further, when a printer abnormality such as a paper shortage occurs, the output is lost, so that it is not recorded as a record.

According to the present invention, in the supervisory control device constituted by using a computer and a microcomputer, a message is printed using a printer when the status change occurs in the monitoring target as the monitoring information of the system. The information recorded by printing is used for investigating the trend of the system and for investigating the cause of the abnormality from the messages before and after the abnormality occurs in the system, and the system is operating normally. If it is, it is considered that it is not necessary to print the expected state change, and therefore a system is provided for the purpose of suppressing the printing by setting the conditions for printing the message. In the supervisory control device, the equipment to be monitored is operated by the manual operation of the operator or the control output from the automatic control program, but these operation output requests are intentionally made from the supervisory control device. It is considered unnecessary to print a message when the status of the device changes.

Therefore, only the information other than the output request from the monitor and control device in which the status change occurs spontaneously is the object of message printing. In addition, it is possible to prohibit message printing for devices that repeat periodically with devices that perform voluntary operation / stop, and save status changes as history data regardless of the above message suppression. Monitoring that has the function to display the history data in hourly / daily units by using the display device of the monitoring control device and can reprint necessary information of the history data. An object is to provide a control device.

[0008]

According to the present invention, there is provided an operation output section for designating a control point for a control target to output an operation command and a mask bit set signal for each control point, and an operation output section. Means to set the operation output mask status of the corresponding control point by inputting the mask bit signal output from the device and the state change signal from the controlled object for each state change point, and request the message for each state change point And whether or not there is a status change output from the status change point corresponding to the control point in response to the operation command output, and if there is no, a status change that resets the operation output mask status for this control point. The operation output masks of the detection point and the control point that receives the message request and corresponds to the state change point Is set, and if it is set, the message output request corresponding to the printing unit is suppressed, and if it is not set, the message edit processing unit is not suppressed. The supervisory control device and the message edit processing unit have a function of saving data regarding all state changes as history data regardless of whether the operation output mask status is set. .

[0009]

In the supervisory control device of the present invention, the automatic operation signal for automatically operating the control device to be monitored is input, the manual operation signal for manually operating the control device is input, and the operator operation requesting section A manual operation signal or an automatic operation signal from the automatic control operation unit is input, and an operation operation command is output to the control device as an operation output request.If the input signal is a manual operation signal, another preset mask time is set. An operation mask bit set signal is output over a period of time, a change in the operating state of the control device is detected, and a state change detection signal and a state message are output as a message edit request as input processing. Detects that the control device does not change its state despite the output of the automatic operation signal, and then the operation mask bit set signal and state change When the output signals are input at the same time, the suppression check signal that suppresses the operation control of the control device is set and output, and the suppression check signal performs the edit processing for printing the status message and outputs the message output request. The history message and the status message saved in the history data saving section are displayed, and the status message is saved as history data regardless of the presence or absence of the operation mask bit set signal by the history saving request from the message edit processing section. The operation output mask status is forcibly reset in response to a change print command from the edit processing unit or an abnormal print command from the status unchanged detection function, and history data and status messages are printed.

[0010]

EXAMPLE An example of the present invention will be described below. In FIG. 1, 20 is an automatic control operation unit for inputting an automatic operation signal for automatically operating the control device 1 to be monitored, 30 is an operator operation request unit for inputting a manual operation signal for manually operating the control device 1, 10 is an operator operation request unit 30
Input a manual operation signal from the automatic control operation unit 20 or output an operation operation command to the control device 1 as an operation output request S1. If the input signal is a manual operation signal, it is determined in advance. The operation output unit 40 that outputs the operation mask bit set signal S5 over the mask time, detects that the operating state of the control device 1 has changed, and outputs the state change detection signal and the state message as a message edit request S3 as an input process. Change detecting section for outputting as 40
Reference numeral a denotes a state invariant detection function for detecting that the control device 1 does not change its state in spite of the manual operation signal or the automatic operation signal output from the operation output unit 10, and 60 denotes the operation output unit 10 and the state. An operation output mask that is connected to the change detection unit 40 and sets and outputs the suppression check signal S6 for suppressing the operation control of the control device 1 when the operation mask bit set signal S5 and the state change detection signal are simultaneously input. A status 50 is connected to the operation output mask status 60 and the state change detection unit 40, and a message edit processing unit 70 for performing edit processing for printing a status message by the suppression check signal S6 and controlling output of the message output request S4. Of the operation mask bit set signal S5 in response to the history storage request S7 from the message edit processing unit 50. A history data storage unit that stores a status message as history data regardless of the existence, a history data display unit 80 that displays the data stored in the history data storage unit 70 and a status message, and a change 2 from the message edit processing unit 50. It is a printing unit that forcibly resets the operation output mask status 60 and prints history data and status messages by a printing command or an abnormal printing command from the status unchanged detection function. When printing the information to be monitored as a message on the printer, regarding the status change in response to the operation output request from the monitoring control device,
In the supervisory control device characterized by having the function of interrupting the printing process, and in the supervisory control device, the information of each state change is saved as history data regardless of the interruption of the message printing, and the history data is displayed using the display device. The monitoring control device is characterized in that it can be displayed in units of hours and days, and a message can be printed by issuing a reprint request.

That is, the purpose of printing the message is to confirm later whether or not the equipment to be monitored is operating as managed by the supervisory control device, and when an abnormality occurs in the system. It is most important to analyze the cause by investigating the messages before and after the occurrence of the abnormality, and the message becomes unnecessary when operating in normal operation. That is, when the monitoring control device manages the schedule of the device to be monitored, the operation output is automatically performed to the device for operation / stop. In addition, when the operation output is performed to the operator device, since the device is operated with the independence of the supervisory control device, the message corresponding to the operation / stop state change is sent to the device in response to this operation output. I think that printing is unnecessary. This condition suppresses messages.

As a method of suppressing this, when the operation output and the automatic control output are performed to the operator in the supervisory control device, the operation output mask is set at the index of the state change point corresponding to the output.

After the operation output, when the monitored object is activated and its state change is detected, the operation output mask is checked from the state change point, and if it is set, message printing is suppressed. At this time, the operation output mask is reset to prepare for the next operation output. If the equipment to be monitored does not operate, after a lapse of a certain set time, it is determined that the operation is not performed, and message printing / warning sound is issued to reset the operation output mask.

In the message printing suppression, the message due to the normal operation is not printed, but the information associated with the status change is necessary for the case where it is necessary to investigate the abnormal operation due to the mistaken operation / automatic control setting information due to the operator's erroneous operation. Save as history data regardless of suppression. Further, the monitor control device is arranged so that this history data can be displayed on the display device in a message print format.
In this history data display, it is possible to display on an hourly / daily basis, and a message can be printed in that unit. As a result, it is possible to select and reprint the information of the state change that was not printed due to the message suppression, so that only the necessary message can be reprinted and analyzed.

FIG. 1 is a block diagram of the message printing suppression type of the present embodiment, in which a control device (monitoring target) 1 is requested by an operation output unit 10, an automatic control operation unit 20, and an operator operation request unit 30. When the operation output mask status 60 is received, the operation mask bit set S5 is performed on the operation output mask status 60. The control device 1 operates in response to the operation output request S1, and the state change is detected by the state change detector 40 in the input process S2. The state change detection unit 40 sends the message edit request S3 to the message edit processing unit 50. The message edit processing unit 50 checks the operation output mask status from the state change point and performs a suppression check S6. If the operation output mask status 60 is set, the message output request S4 is not made. In the message edit processing unit 50, the state change information of the operation output mask status 60 regardless of whether it is set or reset is stored in the history data 70 by the history storage request S7.
If the control device 1 does not operate after the operation output request S1 from the operation output unit 10 is made, the state detection unit 4
At 0, a non-operation message is sent to the message edit request S3 for the operation point, and the operation output mask status is forcibly reset S8.

In the history data display section 80, the history data 70 stored in the message edit processing section 50 is displayed on the display device 3.
It is possible to reprint the message in the printing section 2 by displaying the information in units of hour / day and requesting reprinting of necessary information S9.
