(Problem to be solved by the invention) When performing monitoring operations using the above system.

Operators use operation panels 40 that are spaced apart from each other.
It is necessary to select a device while alternately looking at both the screen and the graphic panel 10, which results in poor operability. Furthermore, the operator is not always near the operation panel 40 in the monitoring room, and the operation panel is usually not easily portable, so the operator must move to the position of the operation panel 40 each time an operation is performed. there were. In particular, as the equipment to be monitored becomes large-scale, the number of devices to be monitored and operated also increases. Therefore, operation using the operation panel not only has poor operability in normal times, but also causes delays in responding to requests for prompt equipment operation in emergencies and other situations. was also invited.

SUMMARY OF THE INVENTION An object of the present invention is to provide a monitoring and control device with good operability that allows monitoring of field equipment from anywhere in a monitoring room by watching only the graphic panel.

[Structure of the invention]

(Means for solving the problem) The monitoring control device according to the present invention graphically displays the monitored object,
A selection display is provided for each of the operated devices, and a graphic panel is provided on which one of these selection displays is displayed. This graphic panel has key switches for movement commands in multiple directions, key switches for selection commands, and key switches for operation commands.
A remote controller is provided for emitting mutually distinguishable remote control signals for each of these key switches. Further, a remote control controller is provided which inputs a remote control signal from the remote control operator via a remote control receiver provided on or near the graphic panel, and identifies which key switch the input remote control signal is caused by. Furthermore, the identification result from this remote control controller is input, and if it is a remote control signal from the movement command key switch, the lighting state is shifted to the selection display in the direction indicated by the key switch based on the selection display currently lit. function to select the operated device corresponding to the currently lit selection indicator if the remote control signal is from the key switch for selection commands, and the selected device to be operated if the signal is from the key switch for operation commands. A monitoring operation controller is provided, each having a function of giving a predetermined operation command to the controller.

(Function) The present invention selects and flickers any one of a plurality of selection displays provided on a graphic panel by operating a key switch of a remote controller, and provides a device corresponding to the flickering selection display. This allows the operator to perform each of the above operations while visually viewing the graphic panel, which improves operability and eliminates the need for the operator to move to the operation panel as in the past. It also enables quick operation.

(Example) A graphic panel according to an example of the present invention is shown in FIG. Note that the same parts as in FIG. 3 are given the same reference numerals.

In FIG. 1, equipment symbols 11 representing the objects to be monitored by the system are attached to a graphic panel 10, as in the prior art. Reference numeral 12 denotes a selection display, and a 6-display controller 13 provided corresponding to each device symbol 11 lights up these symbols 11 and the selection display 12 in red, green, or the like. 14 is a remote control signal receiving section, and a remote control operating device 20
Receives infrared rays, ultrasonic waves, etc. emitted by the device and converts them into electrical signals.

Reference numeral 15 denotes a remote control controller that converts the electrical signal output from the remote control receiving section 14 into a general character code, etc., and outputs it to the controller 30 for monitoring operation.

The remote controller 20 is approximately the same as that used in a regular remote control for a television or the like.

The monitoring operation controller 30 inputs and outputs signals from the on-site electrical equipment 5o, displays the status on the graphic panel 1°, accepts requests from remote control operations, and performs on/off outputs of the on-site equipment. do.

The monitoring operation controller 30 collects information on the field equipment 5o, edits the content, and transmits the content to the display controller 13.The display controller personnel turns on/off the field equipment 50, etc. according to the content. The device symbol 11 is lit in red, green, etc. in accordance with the state. With this system, the status of the on-site equipment is always displayed on the graphic panel 10, and this allows an operator who monitors the equipment to monitor the equipment in a monitoring room or the like that is separate from the actual equipment.

On the other hand, a remote controller 20 is used to perform operations. The operation section 20A of the remote controller 20 includes key switches 20a, 20b, 20c, which are shown enlarged in FIG.
20d, 20e, 20f, and 20g are attached.

The device selection display 12 on the graphic panel 10 is always
One of the points is lit, and this lighting means that the corresponding device is currently selectable.

When the movement command key switches 20a, 20b, 20c, and 20d of the key switches of the remote control operation section 20a are operated, movement command information is transmitted to the monitoring operation controller 30 via the remote control reception section 14 and the remote control controller 15. The operated key switch 20a,
20b.

The dot clique of the selection display 12 on the graphic panel 10 moves corresponding to either 20c or 20d. The operator performs this operation several times and moves the lighting position until the selection indicator 12 corresponding to the device he wants to operate lights up.After the selection indicator 12 of the desired device lights up,
Key switch 20e for selection command of remote control operation unit 20A
By operating , select the device corresponding to the selection display 12 currently lit on the graphic panel 10,
Flicker the corresponding equipment symbol. Note that instead of the device symbol 11, the selection display 12 itself may be flickered. This flicker allows the operator to confirm that the selection of the device has been accepted by the monitoring operation controller.Firstly, the operator can respond to the operation details and operate the remote control to turn on/off the selected device. Part 2
Operate the 0A key switch 20f or 20g. Through this operation, the operator's operation request is transmitted via the supervisory operation controller 30 to a specific device selected from among the field equipment 5o, and the on/off operation is actually performed.

The difference in the output form (combination of frequency and intermittent signal) of the output signal (infrared rays, ultrasonic waves, etc.) from the remote control device is made to correspond to each switch, and the remote control receiver 14 and the remote control controller 15 correspond to each switch. , assigning a specific character code. Transfer this character code from the remote control controller 15 to the monitoring operation controller 30 5R23
By transmitting the operation contents of the remote controller 20 using a transmission method such as 2C, the operation contents of the remote controller 20 can be transmitted to the monitoring operation controller 30.
tell to.

The processing of the monitoring operation controller 30 will be explained using FIG. The remote control controller 15 is the remote control receiver 1
Input the signal wave of the remote controller 20 received at 4,
A controller is used that creates text for each signal type and sends it to the host computer. For example, each received data of the movement command key switches 20a, 20b, 20c, and 20d is A,
The monitoring operation controller 30 can receive the text as texts such as B, C, and D. Further, different PI○ outputs are performed depending on the type of data received from the host computer, and different symbol displays are lit or turned off to flicker.

Hereinafter, data for monitoring and operation will be used to identify the received data from the remote control controller 15 and instruct the display controller 13 to change the display state depending on the content, or to output the operation to the PIO device (not shown) connected to the field equipment 50. The processing of the controller 30 will be explained.

In FIG. 3, the process in step A is performed when remote control operation is performed using the remote control operating device 20.

First, the text received from the remote control controller 15 is checked to identify which key switch of the remote control operation section 20A shown in FIG. 2 has been operated. In the judgment in step B, it is determined that the received text is
It is determined whether or not one corresponding to any one of the movement command key switches 20a to 20d has been operated, and if any one of the movement command key switches 20a to 24d has been operated, the process proceeds to step C, and if not, the process branches to step F. In the process of step C, it is determined whether or not the display position can be changed by a movement command from any of the movement command key switches 20a to 20d inputted to the currently lit point of the selection display 12. Check 6 For example, selection indicator 1 that is currently lit
2 is at the left end of the graphic panel 10, the movement command by the key switch 20c is ignored.

In the determination at step D, it is determined based on the processing result at step C whether or not the selection display 12 can be moved. As a result, if it is possible, the process of step E is performed, and if it is not possible, the 1 selection display 12 is not moved. Step E
In the process, the display controller 13 is instructed to newly light up the selection display 12 according to the current lighting position of the selection display 12 and the input of the movement command key switches 20a to 20d.

On the other hand, in the determination at step F, it is determined whether the input text corresponds to the operation of the selection command key switch 20e, and if so, the process proceeds to step G. If there is no correspondence, the process branches to step H. In the process of step G, it is assumed that the currently lit selection display 12 is selected, and the display controller 13 is instructed to flicker the corresponding selection display 12. At this time, identification information of the corresponding device is stored. In the judgment in step H, it is determined whether the input text corresponds to the input command key switch 20f or the cut-off command key switch 20g. If the input text corresponds to the input command key switch 20f, the process advances to step E, and If it corresponds to the command key switch 20g, the process branches to step J. In the process of step E, based on the identification information of the device to be operated stored in the process of step G, an operation output of ``r input'' is performed to the PIO (process input/output) point corresponding to the device. However, if step G has not been passed and the identification information of the device to be operated is not stored, this process is skipped. In the process of step J, similarly to the process of step E, a "cut" operation is output to the corresponding PIO point.

In addition, in the step process, the remote control controller 15
Wait for the next text to be sent. When the text is received, the process returns to process A, and the same process as above is performed depending on the received text.

The 1 selection display 12 is moved by repeating the above process.

It is possible to select the device to be operated, display the flicker, and execute the operation method.

In addition, when the number of points to be monitored becomes larger in such a graphic panel 10, a key switch for specifying a portion of the graphic panel 10 is provided in addition to the key switch shown in FIG. It is also possible to move the illumination of the selection display 12 in one motion to a portion including the device to be operated, thereby reducing the number of operations of the movement command key switches 20a to 20d, and further improving the operability.

〔Effect of the invention〕

As described above, according to the present invention, since the monitoring operation using the graphic panel 10 is performed using a remote control device, the operator can perform the monitoring operation of the field equipment from almost any point in the monitoring room by looking only at the graphic panel IO. This makes it possible to improve operability during normal operation. Also.

It has the advantage of being able to operate quickly even when operating using a graphic panel displaying many monitoring targets.
