Description

[Detailed description of the invention]

The present invention relates to an erroneous setting display method that displays when an erroneous setting operation is performed by a setting unit such as a switch. When controlling the operating system, a setting part such as a switch is controlled to close or open. In the example of FIG. 1, when the switches SW1 to SW4 are set in combination, there are 16 operating modes as shown in Table 1. At this time, the detection control unit DCT detects and decodes the settings of each switch, and generates appropriate control signals to control the operation control unit CTL. The operation control unit CTL appropriately controls the operation of the predetermined operation circuit. Unless the setter becomes skilled by controlling the 16 types of modes many times, he or she must control the settings while referring to Table 1.

【table】

[Table] The detection control unit DCT also performs translation control as shown in Table 1. In this case, an unexpected mode is set and no abnormal state occurs. However, if the number of setting switches is much greater than four, the number of settable modes will increase, and searching the table will take a long time. SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned drawbacks, and to provide a method that can easily set conditions without having to search for a table, and that can display incorrect settings if they have been made. Therefore, the gist of the present invention is to provide a device that divides the setting sections into a plurality of groups and can display an error message if an incorrect setting occurs. Embodiments of the present invention shown in the drawings will be described below. FIG. 2 is a block diagram showing an embodiment of the present invention.
Each setting switch has three groups G1 to G3.
The number of switches in each group is 3 and 4.
There are 3 pieces. The first group G1 is labeled as a switch, the second group G2 is labeled as a switch, and the third group is labeled as ○a○i○u.
The setting mode obtained by operating each switch is the second
It is limited to the 16 ways shown in the table, and there are no others.

By making simple rules for each number, etc., and remembering only those rules, there is no need to take out a table and look up the setting mode each time, and a predetermined mode can be easily set. This allows for smooth switch operation. However, if an incorrect setting is made, error detection and display ERD can be performed using a simple device such as a combination of logical operation circuits. The detection control section in the embodiment of FIG. 2 includes an arithmetic processing device,
Error detection in switch operation is performed according to the flowchart shown in FIG. In FIG. 3, "abnormal state display" error 1, etc. means that the state mode in which the switch was operated is not in Table 2, and an error is displayed. For example, switch 1st group G1
, if both are not set (not turned on), an "abnormal state display" error 1 will occur. Note that detecting and displaying errors will be described later. In the flowchart of FIG. 3, after processing the "abnormal state display" error 1, the arrow points upward and merges with the case where switch A was previously set. This means that when no settings are made for switches , , , etc., it is sufficient to automatically set . Automatic settings will be explained in detail when error detection is explained. Setting A here means that there are a large number of setting modes for , in other words, that it is given a high priority compared to other switches. The large number of setting modes means that the second group G2
Considering the third group G3 in the same way, in the case of "abnormal state display" error 2 for the second group G2, setting the switch is also activated when none of the switches ~ are set. Further, in the case of "abnormal state display" error 3 for the third group G3, when none of the switches ○a to ○c are set, setting the switch ○a is operated. In addition, in "abnormal state display" error 5, the first group G1 sets the switch of C, and at that time, looking at Table 2, it is necessary that the second group G2 becomes or, otherwise it is abnormal. . At that time, the switch is also set. As described above, when an "abnormal state display" is required depending on the setting state of the switch, an error display is performed, and automatic correction is performed to the state with the largest number of modes. The flow chart shows that when the switch is set normally, the state described as mode X is set. X in mode X is the second
Values from 1 to 16 are taken for the table, and in this case, only one mode is always selected when each switch setting is normal. Next, FIG. 4 shows a logical operation circuit for performing the operation shown in FIG. 3. The original diagram of FIG. 4 shows the circuit for obtaining the "abnormal condition indication" error 1 signal. As mentioned above, when none of the switches - is set, this is calculated using a NAND circuit and error 1 is obtained. When the error 1 signal is detected, the signal and the signal for which no switch is set are further calculated using a NAND circuit to obtain "selection A". Since selection A is a signal that should operate a switch, it is sufficient to drive switch A formed by, for example, an electronic switch. When the "abnormal state display" error 1 occurs, the switch is set and turned on, so that the error 1 state is canceled. Other diagrams in FIG. 4 similarly show circuits that operate on the error detection signal and the signal for selecting a switch. That is, the switch shown in FIG.
. . . An arithmetic circuit is formed by a large number of connection lines from the circuits A to ○C, and the detection control unit DCT includes all of these circuits. The error detection/display ERD uses light-emitting display using light-emitting diodes or audio display. In this manner, according to the present invention, since the conditions are grouped when setting conditions, meaningful expressions can be made, so settings can be made easily without having to search for a table. Furthermore, if an incorrect setting is made, it can be detected and displayed using a simple circuit. Furthermore, since the detection control section is constructed by combining logical operation circuits, it is possible to easily automatically correct any incorrect settings.
