Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to an operation monitoring device interposed between machines and equipment (plants) and humans (mainly operators), and in particular to operation monitoring devices. It has good performance, does not take up much space, and is inexpensive.

[Prior art and its problems]

There are three main ways to configure counterfeit monitoring panels: vertical freestanding type, bench board type, and control desk type.
There are 0 types of vertical free-standing type, which separates the operation section and monitoring section, and the monitoring section has a vertical panel surface, and this panel surface includes a graphic panel showing the plant system diagram, alarm lamps, and meters. (controller, indicator, recorder), and operation switches.The operation section is located in a different position from the aforementioned monitoring section, and the operation panel has instruments, operation switches, and indicator lights. etc. are provided. The bench board type is a system that integrates the operation part and the monitoring part, and structurally it is a combination of a vertical freestanding board and a desk board. Operation switches, signal lights, etc. are mainly mounted on the inclined surface of the desk-shaped board, and instruments and indicators are mounted on the vertical panel surface of the vertical free-standing board. Like the bench board type, the control desk type integrates the operating section and the monitoring section, and can be said to be simpler than the bench board type. The structure consists of a desk-shaped panel with a tilting panel attached to the rear for installing instruments that need to be constantly monitored and controlled, and the main operations can be performed from this panel.

However, with the vertical free-standing type, the operator must memorize the arrangement of the operation switches installed on the operation panel, and the size of the operation switches attached to the operation panel must be larger than a finger, otherwise it will be inconvenient to operate. Therefore, when using a large number of operation switches, a lot of space is required on the operation panel.
Disadvantages include a larger operation panel and the need for signal lines from the switches on the operation panel; bench board and control desk types also have larger operation panels and require signal lines. There were drawbacks such as being

[Purpose of the invention]

In view of the above, an object of the present invention is to provide an operation monitoring device that eliminates the drawbacks of conventional devices as described above.

[Key points of the invention]

This object, according to the present invention, includes a first means for outputting a device selection signal through space at an arbitrary position, and a device control through space at an arbitrary position to which the device selection signal is applied by the mosquito means. This is achieved by comprising a monitoring panel having a monitoring panel in which is embedded a detector for receiving at least the device control signal;

[Embodiments of the invention]

FIG. 1 is a schematic configuration diagram showing an embodiment of an operating device according to the present invention. In the figure, 1 is the monitoring panel, 2 is the operation panel, and 3

is drawn, and the instruments 13 include, for example, a controller 1.
31, and the operating device 21 further includes a selection knob 210. Control switches 211, 212, 213 are provided.

Embedded in the graphic symbol 111 are a detector and a lamp that output a contact signal when sensitive to four types of light of specific wavelengths 'a # '1) -'ca f6. The operating device 21 is a selection knob 210. Control switch 211, 21
When the user operates the 0 selection knob 210, which emits light to any arbitrary point on the monitoring board 1, by operating 2.213, the light f1 moves to any 9 points on the monitoring board l. That is, when the control target is specified using the selection knob 210 and the control switch 211 is then operated, the light fb is emitted.

For example, when the control switch 212 is operated as a pump start command, light f0 is emitted. Furthermore, when the control switch 213 that issues a pump stop command is operated, light fd is emitted.

A method of using the operating device configured in this way will be explained.

In FIG. 1, a graphic symbol 111 represents a pump, and when an operator wishes to start this pump, he or she operates a selection knob 210 to illuminate the graphic symbol 111 with light f&. The detector embedded inside detects this and outputs a selection signal. Next, by pressing the control switch 211, the light f1 is emitted and hits the graphic symbol 111, and the detector embedded inside detects it and issues a pump start command to the pump control panel based on the AND condition with the aforementioned selection signal. (not shown). This causes the graphic symbol 111 to light up when the pump starts.

To stop the pump, when the control switch 212 is pressed, a light f0 is emitted and hits the graphic symbol 111, a detector embedded therein detects it and outputs a pump stop command to the pump control panel.

When the pump stops, the graphic symbol 111 goes out. Although the control switch 213 is a backup, it can be used as a reverse rotation command when three-position control is required, such as with an electric valve.

For reference, an example of how the control switches 211, 212, and 213 are used is as follows. ,' FIG. 2 is a block diagram of the detector embedded in the graphic symbol 111, in which four photoelectric conversion elements 1 to A4 are embedded in the graphic symbol 111.
The output of each photoelectric conversion element 1 to A4 is set to logic level II.
It is composed of conversion circuits B1 to B4 that convert into signals of "I, 1g" and a signal processing circuit C that processes the output signals of each conversion circuit B1.B4.
is light of a specific wavelength 'sL*'b, f6.

Elements each sensitive to fa are used, and each element is collectively embedded at a graphic symbol 111. In addition, the signal processing circuit C includes each conversion circuit B1 to B.
4 is input, and an output signal is output to a lamp or a controlled device according to predetermined conditions. For example, the output of the conversion circuit B1 corresponding to the photoelectric conversion element A1 sensitive to light f1 and the output of the conversion circuit B2 corresponding to the photoelectric conversion element 2 which is sensitive to the light f13, and is configured to generate the pump activation command as described above. Such a circuit can be easily realized using logic circuits.

In the description of the above embodiments, light of a specific wavelength'&s
'b e 'Oa 'L is used, but the following modifications are possible.

(Modification 1) Electromagnetic waves of a specific frequency are used instead of light fb#fO#'d, and photoelectric conversion elements A2. A3. Let A4 be a detector that detects electromagnetic waves of this specific frequency.

(Modification 2) The photoelectric conversion element A1 sensitive to light flL is eliminated, and the light f
, L are visible light rays, and the operating device is configured so that the light '1) #'Oe 'a hits the graphic symbol that is hit by this light f1.

(Modification 3) A graphic symbol 111 shows light f of a specific wavelength.

A detector is embedded that has a circuit that is sensitive to this and measures the ON-OFF cycle (intermittent cycle) of the light f, L. Accordingly, the operating device 21 is configured as follows. First, it is assumed that light is emitted to any point on the monitoring panel 1 by operating the selection knob 21O1 control switches 211, 212, and 213. Here, when the selection knob 210 is operated, the light f moves to an arbitrary point on the monitoring panel 1. That is, selection knob 2
10 specifies the controlled object. Next, control switch 2
When you operate 11, the light f is emitted once per second (e.g. 1
00Hz) is configured to be intermittent. This is taken as a pump start command. Furthermore, when the control switch 212 is operated, the light f is emitted twice per second (for example, at 200 Hz).
) Configure it to be intermittent. The burr is used as a pump stop command.

Furthermore, when the control switch 213 is operated, the light f becomes 1
The configuration is such that fa is intermittent three times per second (for example, at 400 Hz).

With this configuration, operations are performed as follows. In Figure 1, graphic symbol 11
1 indicates the pump as described above, and when you want to start this pump, operate the selection knob 210 and shine the light f on the graphic symbol 111 to specify the graphic symbol to be operated.0 Next, press the control switch 211. (when operated), the light f, is intermittent at Zoo Hz, and when this hits the graphic symbol 111, the detector embedded inside detects this 10
Since the intermittent frequency of 0 Hz is detected, a pump start command is output to a pump control panel (not shown). When the pump starts,
The configuration is such that the graphic symbol 111 is lit. When stopping the pump, press the control switch 21
By pressing (operating) 2 to intermittent the light ftL at 200 Hz, the detector embedded in the graphic symbol 111 detects the intermittent frequency of 200 Hz and outputs a pump stop command to the pump control panel. At this time, the graphic symbol 111 is configured to turn off when the pump stops. Note that the control switch 213 is a spare as described above. Also in this case, a method such as using electromagnetic waves as in Modified Example 1 may also be considered.

In addition to this, many other modifications are possible, such as integrating the operation panel 2 and the operation device 21 or making the operation device 21 portable. Furthermore, in addition to light beams and electromagnetic waves, ultrasonic waves and laser light can also be used. [Effects of the Invention] According to the present invention, light beams and electromagnetic waves of a specific wavelength are emitted toward a predetermined position based on an operation command. The following effects can be obtained by constructing the device and a device equipped with a detector that receives and is sensitive to light beams or electromagnetic waves of a specific wavelength.

(1) Since it is no longer necessary to provide a large number of operation switches on the operation panel, (a) the space required for the operation panel and the manufacturing cost of the device are reduced.

(0) Since there is no need to memorize the arrangement of the operation switches on the operation panel, the operation by the operator becomes easier.

e→ Signal cables for externally outputting operation signals from control switches are no longer required, reducing on-site construction costs.
Moreover, it is possible to eliminate erroneous signal output due to induced noise via the signal cable.
