Description

[Detailed Description of the Invention] This invention relates to an improvement of the program timer proposed in ``Japanese Unexamined Patent Publication No. 57-118188,'' and is specifically designed to directly display the location of a card entry error.

<Background of the invention> For example, in schools, factories, etc., a device called a program timer has been put into practical use as a control device that controls the start-up of various loads such as time signal generators, lighting lights, and air conditioners according to preset programs. There is.

Conventionally, a numeric keypad switch has been used as a means for inputting data regarding the on/off times of each load of this program timer. However, when there are a large number of loads and when there are many set times for start and stop control, the input operation using the ten key switch has the disadvantage that it takes time.

For this reason, a program timer has been proposed in which a time setting field is provided on the card, a mark is attached to this time setting field, and data regarding the on/off time of each load can be entered by reading this card with a card reading means. It's being served.

<Disadvantages of the prior art> The program timer proposed in Japanese Patent Application Laid-open No. 57-118188 has a card reading means, and detects a writing error on the card in a program timer in which a program is inputted by a card. Based on the detection, it had a function to display which part of the writing error was made.

FIG. 1 shows an example of a card used in this type of program timer. 101 in the figure is a time designation column;
Reference numeral 102 indicates a condition setting column. Reference numeral 103 indicates a timing mark, and in synchronization with reading the timing mark 103, the time designation field 101 and the condition setting field 102 are read.

The condition setting field 102 includes a load designation field 102a, a time signal/timer designation field 102b, and a day of the week designation field 102.
c and a blowing time designation field 102d.

The program timer proposed in Japanese Patent Application Laid-open No. 118188/1988 has these designation columns 101, 102a,
102b, 102c, and 102d are each defined as one area, and whether or not there is a writing error in each area is displayed. In other words, the time display section shows EE:
It is displayed as EE ₁ or EE:EE ₂ to EE:EE ₅ , and this display indicates in which area there is a writing error.

Specifically, when EE:EE ₁ is displayed as shown in FIG. 2A, it indicates that there is a writing error in the load designation field 102a. This load specification field 102a
A description error is detected when no load designation mark is attached at all, or when multiple loads are designated.

When EE:EE ₂ is displayed as shown in FIG. 2B, it indicates that there is a writing error in the time signal/timer specification field 102b. Time signal-timer specification field 102b
Possible writing errors include not marking either the time signal or the timer, or marking both the time signal and the timer.

As shown in Fig. 2C, when EE:EE ₃ is displayed, it means that when the time signal is specified in the time signal-timer specification field 102b, the sound time (the time the chime is sounding) is specified in the sound time specification field 102d. Indicates a non-existent state.

As shown in FIG. 2D, when EE:EE ₄ is displayed, it indicates that no day of the week designation mark is attached to the day of the week designation column 102c.

As shown in FIG. 2E, when EE:EE ₅ is displayed, it indicates that there is an error in the time specification field 101. A writing error in the time designation field 101 is detected if no time designation mark is placed in the time designation field 101 at all, or if two or more marks are placed in each column of hours and minutes.

In this way, in the conventionally proposed program timer, each specification field 101, 102a, 102b, 102
c and 102d are each treated as one area, and a signal is used to indicate whether or not there is a writing error in each area. Therefore, the user must remember which area the displayed signal indicates a writing error or must prepare a comparison table. Furthermore, in the case of a writing error in the time designation column 101, the location of the writing error is not specified, making it difficult to search for the writing error.

<Purpose of the invention> This invention aims to provide a program timer that can directly display the location of a writing error.

<Summary of the invention> In this invention, the data read from the card reading means is sequentially judged as good or bad by the pass/fail judgment means, and only when the judgment result is good is the data sequentially stored in the storage means, and when the judgment result is bad, it is stored in the storage means. A means for prohibiting the storage of data to be read thereafter is provided, and the data after the part where the writing error occurred is prohibited from being written to the storage means, and at the same time, the last data written normally is displayed on the display. It is configured so that it is displayed on the screen.

Therefore, according to this invention, the location where there is a writing error can be displayed based on the content displayed on the display section, and the work of searching for the location where there is a writing error can be omitted, and an easy-to-use program timer can be provided.

<Example of the invention> Fig. 3 shows an example of the invention. 30 in the diagram
1 indicates the card shown in FIG. 302 is a reading means of this card 301, and 303 is an input port. Input port 303 is connected to central processing unit 305 via bus line 304 . The bus line 304 has a ROM 30 in addition to the input port 303.
6 and RAM307 are connected, and these ROM30
6, RAM 307, and central processing unit 305 constitute a microcomputer 308. The microcomputer 308 operates in synchronization with clock pulses supplied from a clock generator 309 such as a crystal oscillator, and counts the clock pulses supplied from the clock generator 309 to store the current time and day of the week in the RAM 30.
7 and performs constant clock operation. The current time and day of the week are displayed on the display 300.

Reference numeral 311 indicates storage means for storing data read from the card reading means 302. This storage means 311 can be constituted by RAM.
In this example, external to the microcomputer 308
Shows the configuration with RAM connected. In this example, the card 301 has the number 1 representing each load number,
By printing 2, 3, 4, 5, 6 and blacking out one of the numbers 1 to 6 representing this load number, the load is specified, and the storage area of the specified load is A case is shown in which data is stored in _M1 to _M6 . Note that if a card with the same load specified is passed through the card reading means 302 multiple times, the previous memory will be erased and the last read data will remain as memory.

312 indicates an output port. This output port 3
Reference numeral 12 has a function of controlling the output switches S ₁ to S ₆ to turn on and off. In other words, microcomputer 30
8 searches the data of each load stored in the storage means 311, compares it with the current time and day of the week, and when they match, output switches S ₁ to _{S 6} corresponding to that load are searched.
It is used to control on or off. The on/off command for the output port 312 is sent to the storage means 3.
The conditions stored in 11 are transferred to the microcomputer 30.
8 decodes and output switch according to the decoding result.
Control S ₁ to S ₆ on or off. 313a-3
13f indicates an output terminal, and this output terminal 313a
By connecting loads (not particularly shown) to 313f, each load can be controlled to start and stop according to preset data.

The configuration up to this point is the same as a conventionally known program timer.

In this invention, means 314 for determining the quality of data read from the card reading means 302;
When the determining means 314 detects a data defect, a means 315 for prohibiting the operation of storing data after the portion where the defect occurs in the storage means 311; Means 316 is provided for displaying on the display 300 the data read immediately before.

These means 314, 315, 316 can be constituted by ROM. In other words, there is a program for determining whether the read data is good or bad, a program that prohibits the operation of storing subsequently read data in the storage means 311 when a defect is detected, and one of the data determined to be defective. The configuration can be such that programs for displaying previously read data on the display 300 are written in the ROM, and the microcomputer 308 sequentially executes these programs.

These programs can be created, for example, as shown in FIG.

In the flowchart shown in FIG. 4, steps 1 to 4 represent a program constituting the means 314 for determining whether or not there is a writing error on the card 301. The step is a program constituting the means 315 for inhibiting the operation of writing data to the storage means 311 when the determination means 314 detects a writing error, and the step is a means for specifying the location of the writing error and displaying the data on the display 300. 3
16 is shown below.

<Operation and effect of the invention> As described above, according to this invention, when there is a writing error on the card 301, the data immediately before the part where the writing error exists is displayed on the display 300, so that the writing error is eliminated by that display. You can specify the location.

In other words, if no display is made at all, the first
This indicates that there is a writing error between columns 104 to 6th column 105 or in the load specification column 102a.

Also, when the data set in the first setting frame 112 of the time specification field 101 is displayed on the display 300, the data set in the 7th column 106 to the 10th column 107 of the time specification field 101 is displayed.
It is displayed that there is a mistake in the entry, or there is a mistake in the entry in the time signal/timer specification field 102b.

If the data set in the second setting frame 113 of the time specification field 101 is displayed on the display 300, there is a writing error between the 11th column 108 to the 18th column 109 of the time specification field 101 or in the day of the week specification field 102c. It shows that.

When the data in the fourth setting frame 114 of the time specification field 101 is displayed on the display 300, the time specification field 1
It is displayed that there is a writing error between the 19th column 110 and the 50th column 111 of 01 or in the blowing time specification field 102d.

When the data set in the N-th setting frame 115 of the time specification field 101 is displayed on the display 300, it is displayed that there is a writing error in the 50th column 111 and after of the time specification field 101.

As described above, according to this invention, by looking at the data displayed on the display 300, it is possible to know the location of a writing error. Therefore, there is no need to create a comparison table for associating display and description errors, and an easy-to-use program timer can be provided.

<Other Embodiments of the Invention> In the above description, an example has been described in which the condition setting field 102 is arranged side by side with the time designation field 101. According to the above example, each condition setting field 102a, 102b,
It is determined whether the descriptions 102c and 102d are correct, and if they are correct, the time data up to the position where the condition setting column exists is written into the storage means 311. Therefore, considering that there are fields with a large number of settings such as the blowing time designation field 102d, it is necessary to use a buffer memory (this is RAM 307 built in the microcomputer 308) for temporarily storing data read by the card reading means 302. (to use) must be increased in capacity.

For example, when the data of the time setting frame 114 is displayed, whether there is a writing error in the blowing time specification field 102d or whether this blowing time specification field 1
Since it is necessary to determine whether there is a writing error in the time designation column 101 opposite to the frame 02d, it is difficult to search for writing errors in this part.

In order to eliminate this inconvenience, we devised a card as shown in Figure 5.

This card has a condition setting field 102 written before a time designation field 101. By writing the condition setting column 102 before the time specification column 101 in this way, the element (for example, an optical element) for reading the time specification column 101 in the card reading means 302 can be used for reading the condition setting column 102. . As a result, there is an advantage that the number of reading elements can be reduced.

In addition to the advantage of being able to reduce the number of reading elements, the card shown in FIG. 5 provides significant advantages as described below.

In other words, the condition setting field 102 is replaced by the time specification field 101.
According to the arrangement order, for example, the load specification column 102a, the hourly signal-timer specification column 102b, the blowing time specification column 10.
2d and the day of the week specification field 102c, while checking the quality of the data. Also, since the time specification field 101 is read sequentially following this condition setting field 102, each entry frame 501, 50
The quality can be checked in units of 2,503,504,...

As a result, when a writing error is detected, by displaying the data of the previous entry frame, the location where the writing error exists can be identified and displayed.
Therefore, compared to the case of using the card described in FIG. 1, there is no need to search for a place where a writing error exists in order to reliably indicate the place where a writing error exists.

Furthermore, when using the card shown in Figure 5, each entry frame 501, 502, 503, etc. is checked for mistakes, and if the entry in that frame is correct, the data entered in that frame is can be stored in the storage means 311. Therefore, the capacity of the buffer memory is 501, 502, 503, 504.
. . . only one buffer memory, that is, the RAM 30 of the microcomputer 308.
There is also an advantage that the capacity of 7 can be reduced.

Next, an embodiment using the card shown in FIG. 5 will be described. When using the card shown in Figure 5,
The display device 300 is provided with a display section as shown in FIG. That is, a day of the week display section 601, a time display section 602, a timer display section 603, and a time signal display section 6.
04 and a blowing time display section 605 are prepared.

For example, enter 8 in the time designation column 101 of the card.
This section explains the case where you enter 9 o'clock, 10 o'clock, 11 o'clock, and 12 o'clock.

When this card is passed through the card reading means 302, when 12:00 is displayed on the display 300, it is understood that all the data stored on the card has been written correctly and all the data has been written to the storage means 311. .

On the other hand, when the card is passed through the reading means 302, the seventh
As shown in FIG. A, when the display 300 is in a blank state, it indicates that there is a writing error in the load designation column 102a that was read first. A description error in the load specification field 102a is when two or more loads are specified, or when no loads are specified at all.

When any number from 1 to 6 representing the load number is displayed in the blowing time display section 605 on the display section 300 as shown in FIG. 7B, this number is displayed in the load specification column 102
Indicates the load number specified in a. This display indicates that there is a writing error in the time signal/timer specification field 102b. Time signal - timer specification field 102
The error in b is that either the time signal and the timer were both specified, or both were not specified.

When either the timer display section 603 (or the time signal display section 604) is displayed on the display 300 as shown in FIG. . If you make a mistake in writing in the blowing time specification field 102d and enter two or more marks in the 10th or 1st place of seconds, or if you do not enter the blowing time even though it is a time signal, or if you specify the blowing time even though you have specified a timer. This is a case where a mark is entered in the column 102d.

As shown in FIG. 7D or E, the timer display section 60
3) If the blowing time is displayed in the time signal display section 604 and the blowing time display section 605, the blowing time specification field 1
It is displayed that there is a writing error in the day of the week designation column 102c read next to 02d.

An error in writing in the day of the week designation field 102c is when there is no day of the week designation at all.

As shown in FIG. 7F, when the day of the week display section 601 of the display 300 is in the display state,
It is displayed that there is a writing error in the first entry frame 505 of 01. Also, if 8:00 is displayed as shown in Figure 7G, time specification field 101
It is displayed that there is a writing error in the second entry frame.

In this way, by displaying the data of the previous entry frame in which the entry error exists on the display 300, the entry space in which the entry error exists can be identified, which saves the time and effort of searching for the location where the entry error exists. It is convenient because it can be omitted.

In addition, the timing mark 103 on the card is dirty.
Or, if the number is over or under counted due to damage, it is also displayed as a writing error. In this case, for example, as shown in FIG. 7H, the time display section 6
Assume that E is displayed at the beginning of 02.

FIG. 8 shows, as a flowchart, an outline of a program for operating the microcomputer 308 when the card of the type shown in FIG. 5 is used.
In this flowchart, steps 1 to 3 constitute a determining means 314 for determining whether the entries in each entry column shown in FIG. 3 are good or bad. Further, the step constitutes means 315 for prohibiting data read after the location where the writing error exists from being stored in the storage means 311 when the determining means 314 detects a writing error. Further, the step is means 3 for displaying the data at the final address of the data stored in the storage means 311 when the card is read normally or when a writing error is detected.
It consists of 16.

Although the ROM constituting each of these means 314, 315, and 316 is provided outside the microcomputer 308 in the example of FIG.
These means 314, 315, 316 are implemented using a part of the ROM 306 in the microcomputer 308.
It is also possible to store a program for configuring the .

As explained above, according to this invention, if there is a writing error on a card, a display is made so that the location of the writing error can be seen, so there is no need to search for the writing error, making it easier to use. Can provide a good program timer.
