Abstract

PURPOSE:To confirm misoperational contents on an operation desk by displaying the result discriminated whether or not the operation contents from the operation desk are effective on the operation desk. CONSTITUTION:After the contact point of a push button switch 2 with a display part is fetched and an electric signal conversion is performed, a signal is inputted to a controller, and the interlock between the respective push button switches 2 with the display part is obtained and only its result is linked. An answer back for the result is transmitted from a DDC computer to the controller. Based on the transmission result, the controller carries out the control of lighting, lighting-off and flickering by way of the display of the push button switch 2 with the display part and a displaying control circuit. When a displaying instruction is transmitted from the DDC computer to a massage display part 3, the instruction is displayed through the message circuit. Thus, the discovery of the misoperation can be confirmed by the flickering of the push button switch.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a driving desk, and particularly to a driving desk suitable for facilitating the detection of misoperations.

[Conventional technology]

As shown in Fig. 2, in the conventional operation desk, an operation switch was prepared for each machine to be controlled and placed on the desk panel.

A known example of this type is JP-A-55-94503.

[Problem that the invention seeks to solve]

In the above-mentioned conventional example, no consideration was given to the early detection of mistakes made by the person operating the driving desk, and eliminating mistakes was left to the skill of the person operating the desk.

In other words, a misoperation is recognized by visually confirming that the controlled object does not perform a predetermined operation despite the operator's operation of the operating desk.

Therefore, in many cases, unless a person is sufficiently skilled, visual confirmation takes time and results in a decrease in production efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide a desk that allows the driver to confirm the details of the operation error at the driver's desk in order to minimize the time spent on visual confirmation.

Means for Solving Problem C] The above object is achieved by displaying on the driver's desk the result of determining whether or not the contents of the operation from the driver's desk are valid.

As a means for achieving this object, the present invention employs a push button switch with a display section as the operation switch, and also provides a message display section for displaying the cause of the erroneous operation.

[Effect]

An intelligent driving desk 1 according to the present invention has a configuration as shown in FIG.

- The contact of the pushbutton switch 2 with a display section is taken into the contact interface direction, and after electrical signal conversion is performed, it is input to the controller.

Inside the controller, each pushbutton switch 2 has a display section.
D to take an interlock between and output to the controlled object.
Only the results are linked to the DC computer.

An answerback regarding the above result (command to the DDC computer) is transmitted from the DDC computer to the controller.

Based on the transmitted content, the controller controls the display of the push button switch 2 with a display section to turn on, turn off, and blink 9 via the display control circuit.

Further, when there is a display instruction from the DDC computer to the message display section 3, the controller displays the message on the message display section 3 via the message display circuit.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a board diagram of the intelligent driving desk 1.

Push button switch 2A with display section belonging to the function under the application nameplate 4A, 4B, 4C, 4D, 4H.

2B, 2G, 2D, and 2E are arranged.

The message display section 3 uses a liquid crystal panel and has an application name plate 4A.
~ Placed at the top of 4E.

The structure of the pushbutton switch 2 with a display section is shown in FIG.

The pushbutton switch body has switch contacts and LEDs.
It has a built-in semiconductor lamp.

A translucent operation nameplate and a transparent cover are attached to the top of the pushbutton switch body, and when viewed from above the cover, the L
The structure is such that it is easy to check whether the ED is lit or not.

The contact of this pushbutton switch 2 with a display section is converted into a TTL level signal by the contact interface circuit described above, and then taken into the controller.

The controller checks the rationality of the input signal from the pushbutton switch 2 with display section.

Here, rationality is an operational constraint predetermined by the controlled object.

The content of the rationality check is performed as shown in the flowchart of FIG. 5, and the number of constraint conditions i is determined in advance for each pushbutton switch with a display section.

Therefore, the controller has a rationality check program for each pushbutton switch 2 with a display section.

Suppose now that a pushbutton switch with a display section is pressed and the th condition among the number i of constraint conditions shown in FIG. 5 is not satisfied.

In this case, the controller blinks the display section of the push button switch 2 with a display section that corresponds to the second condition. This blinking continues for 3 seconds in this embodiment.

For example, the rationality check flow when the pushbutton switch 2E with a display part of an automatic machine is pressed to change rolls is shown in FIG.

As can be seen from the flow, the number of constraint conditions for establishing automatic operation is three, and when each condition is not satisfied, the LED of the corresponding pushbutton switch 2 with display section blinks.

When all three conditions are met, an automatic construction command is issued to the DDC computer.

Even if the operator operates this operation desk when the constraint conditions are not met, he or she can easily correct the misoperation by turning on the flashing pushbutton switch with display. .

In this way, an operator's erroneous operation can be easily recognized by the flickering of the pushbutton switch with display section, but if the controlled object cannot be operated due to conditions other than the operation desk, the cause is displayed on the message display section 3. There is.

Conditions other than this operation desk include turning on the safety switch,
Examples include turning on the power of a controlled object and selecting an operation location.

Since these conditions are the conditions of the plant monitored by the DCC computer, the controller recognizes the error code sent from the DDC computer to the controller and displays it on the message display section 3 via the message display circuit.

The method for converting an error code into a message is performed within the controller according to the flow shown in FIG.

In the present invention, an arrangement is made between the DDC computer and the controller so that a plant failure condition corresponds to a specific error code.

In the controller, a message corresponding to the received error code is predetermined, a process is performed to search for a message with a one-to-one relationship based on the error code, and the message is immediately displayed on the message display section 3 (hereinafter, this process will be described). (referred to as decoding). By determining in this way, each failure condition of the plant has a bijective relationship with a one-to-one correspondence with the message displayed on the message display section 3.

This relationship is as shown in FIG.

As mentioned earlier, there are two types of displays on the operator's desk in response to a misoperation: the flashing of the pushbutton switch with display 2 and the message on the message display 3, but the display on the operator's desk during normal operation is as follows. The pushbutton switch with display section is turned on and off by receiving an answerback from the DC computer.

Processing within the DDC computer performs predetermined content for each command from the controller. This process is a flow shown in FIG.

If any of the plant conditions are not satisfied, an error code is issued as described above.

On the other hand, if all of the conditions are true, the output is output to the controlled object and an answerback is returned to the controller.

The controller receives this answerback and turns on or off the display section of the push button switch with display section that was pressed.

〔Effect of the invention〕

As described above, according to the present invention, detection of operational errors, which conventionally relied on experience, can be easily confirmed by the flashing pushbutton switch on the operator's desk, and causes not directly related to the operator's desk can be confirmed on the liquid crystal display. Therefore, it not only does not require a particularly skilled operator, but also makes it possible to easily avoid misoperations, which has the effect of improving production efficiency.
