Description

[Detailed description of the invention] This invention relates to a program timer that controls starting and stopping of various loads such as time signal generators in schools, factories, etc. In particular, this invention uses card reading means to set settings for controlling the starting and stopping of loads. This invention relates to an improvement to a program timer that allows input by reading the data.

<Description of the Prior Art> A device called a program timer has been put into practical use for the purpose of, for example, making a time signal to notify the start and end of work in schools, factories, banks, etc., and for turning on and off the power of lighting lights and air conditioning equipment. ing.

This program timer operates a load such as a chime every time a set time, which is constituted by a general timing device and a set time storage means, is reached. When controlling other loads such as air conditioning equipment, lighting lights, pump security equipment, etc. in addition to the timer, a set time storage means is provided for each of these loads, and a set time storage means is provided for each of these loads. Each load is controlled.

Conventionally, the means for setting the time in the set time storage means provided for each load has generally been inputted from a keyboard. However, inputting from a keyboard is a time-consuming and troublesome task when there are many settings.

For this reason, a recent trend has been to write a code corresponding to the set time on a card, and to make the setting possible by having the code read by a card reading means.

A conventional card input type program timer will be explained using FIGS. 1 and 2.

FIG. 1 shows a schematic structure of a conventional card-type program timer. In the figure, 101 is a microprocessor, and 102 stores a program for operating the microprocessor 101 in a predetermined order.
ROM, 103 and microprocessor 101
Timekeeping means 104 measures the current time and day of the week in cooperation with the ROM 102, and numeral 104 is a set time storage means. This storage means 104 can be constituted by a RAM, and is provided with a number of areas corresponding to the number of loads to be controlled, for example, A, B, C, D, E, and F.

105 indicates a card reading means. By inserting the card 106 into the card reading means 105, the program written on the card 106 is read, for example optically, and taken into the set time storage means 104 from the input port 107 via the microprocessor 101.

108 is an output circuit. This output circuit 108
The set time stored in each area A to F of the set time storage means 104 through the search by the microprocessor 101 is constantly compared with the current time and day of the week measured by the clock means 103, and the current time and day of the week are compared. When coincides with the set time stored in the storage means 104, the output switch SA~ corresponding to that storage area is activated.
SF is controlled on or off, output terminal 109
Each load (not particularly shown) connected to a to 109f is controlled to start and stop.

FIG. 2 shows an example of entries on the card 106. The card 106 has a time entry field 201 and a condition setting field 20.
2 are provided. The condition setting field 202 includes a load specification field 202a and a time signal/timer selection field 202b.
, day of the week specification field 202c, and blowing time specification field 20
2d is provided.

The load specification field 202a has a set time storage means 10.
Symbols A to F are printed corresponding to areas A to F provided in 4, and when specifying a load, the load is specified by filling the symbol corresponding to the load in black with, for example, a pencil. One load can be specified per card. That is, for example, when controlling the lighting of advertising lights using the load designation symbol A, the symbol A is painted black. In the time signal/timer selection column 202b, if the load is an advertising light, the column on the timer side is filled in black. Furthermore, in the day of the week designation field, all days of the week on which advertising lights should be turned on are filled in black. Then, in the time entry column 201, the lighting time and light-off time are written in black. In other words, the first column of the time entry field 201 represents the 10th digit of the hour,
The second column represents the first digit of the hour. The third column is for minutes.
The 10th column represents the value of the 10th place, and the fourth column represents the value of the 1st place of minutes. So, for example, to write 12:30, write the time by blacking out "1" in the first column, "2" in the second column, "3" in the third column, and "0" in the fourth column. can be filled in. Enter the time when the advertising lights will be turned off in the next column.

<Conventional Disadvantages> In this type of conventional card input type program timer, a storage area is designated for each load. Therefore, as explained above, in cases such as controlling the lighting and turning off of advertising lights, only two storage areas designated for the load are used for turning on and turning off the lights. Therefore, in such cases, many memory elements are wasted.

On the other hand, some types of loads require programs that are too long to be written on one card. In such cases, conventionally, a long program is divided into multiple parts, and the divided programs are distributed and stored in multiple storage areas.

In this way, when one load is controlled by a program distributed over multiple storage areas, for example B and C, output switches SB and SB corresponding to areas B and C are used.
SCs are connected in parallel, and one load is controlled by the contact outputs of the parallel-connected output switches SB and SC. Therefore, when there is a large load that requires a long program, there is a drawback that the storage area becomes undefined.

In this way, according to the conventional card input type program timer, even if there is a blank storage area,
There is a drawback that the storage means 104 cannot be used effectively because the storage area cannot be used to store programs for other loads.

Further, the conventional program timer has a structure in which, when a holiday is designated, no contact signal is output to any load on the designated day. Therefore, even if there is a load that you want to operate on holidays in the same way as on normal days, there is a drawback that you cannot operate that load independently. For this reason, conventionally, if there is a load that you want to operate normally, you do not specify a holiday and manually turn off the output to other loads on that day, giving contact output only to the load that you want to operate normally.

In this case, the switch that was previously operated must be turned back on after the holiday has passed, and if this is ignored, other loads will not operate properly the day after the holiday, causing confusion and is a major inconvenience. .

<Purpose of the invention> The purpose of this invention is to provide a program timer that allows the user to freely input even a long program related to one load, and also allows holidays to be specified for each load.

<Summary of the invention> In this invention, instead of specifying a storage area for each load in the set time storage means, the input program is stored sequentially from the first address, and an additional writing field is added to the card. A holiday designation field is provided, and by adding an additional mark and a holiday mark to the additional entry field and holiday designation field, it is possible to designate a holiday for a program that has already been input.

Therefore, according to this invention, since a storage area is not specified for each load, even a long program for one load can be stored, and holidays can be specified for each load.

<Embodiment of the invention> Fig. 3 shows an embodiment of this invention, and Fig. 4 shows a card used in the program timer of this invention.
In FIGS. 3 and 4, parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals.

The structure characterized by this invention is the card reading means 1.
means 301 for determining whether the program written in the load description column 202a input from 05 already exists in the storage means 104; and the storage means 104
Means 30 for detecting an address in a vacant state
2, and an additional entry column 4 shown in FIG. 4 on the card 106.
01 and a holiday designation field 402, a means 303 for detecting that an additional mark has been added to this additional entry field 401, and a means 303 for detecting that a holiday designation mark has been added to the holiday designation field 402, The present invention is characterized in that a holiday storage means 304 is provided for causing the described load to operate on holidays on designated days of the week. In the example shown in FIG. 4, loads A, B, and C are designated as a holiday on Wednesday.

<Description of operation of the invention> If the input card does not have an additional mark attached, the determining means 301 determines whether or not the program in the load description field 202a attached to the card already exists in the storage means 104. . Storage means 10
If no program related to the load is stored in 4, the programs of the cards inputted are stored in order from the earliest address of the free area.

Therefore, in the initial state, a card is created for each load,
By sequentially inserting the cards into the reading means 105, programs related to each load are stored in the storage means 104 in the order in which they were input, starting from the first address. Note that an appropriate amount of blank space can be provided between each program, and the program can be configured to be extended to some extent using this blank space.

In a state where a program related to a certain load is stored in the storage means 104, when a card specifying that load is inserted again, the determination means 301 detects this, erases the previously stored program, and fills the empty space. Stores programs entered later. Therefore, in order to change the operation of a load, the program can be rewritten by writing the changed program on the card specified for the load in the load setting field 202a and inserting it into the reading means 105.

For example, if the program cannot be stored on one card due to the type of load, in this invention, an additional mark (the inside of the "" in the additional entry field 401 is painted black) is placed in the additional entry field 401 of the second card. All you have to do is write the program following the first card on the card with the additional mark and insert it into the card reading means 105.

When an additional mark is attached in this way, the additional mark detection means 303 detects the additional mark, thereby prohibiting the erasing operation of the previously stored program related to the same load. Therefore, even if a program related to the same load is already stored in the storage means 104, the program related to the same load can be stored in an empty address without erasing the stored program. Therefore, even if the program is too long to fit on one card, it can be divided into several cards and input.

The program stored in the storage means 104 is compared with the current time measured by the timer means 103 by the read operation, and if the current time and the set time and day of the week match, the program is changed to the load according to the load information attached to the program. Corresponding output switch SA~SF
is operated on or off to control the load.

Furthermore, according to this invention, a holiday storage means 304 is provided so that when a holiday mark is read, the designated load and day of the week are memorized, and based on this memory, the designated load is stored on the day of the week designated as a holiday. It is possible to prohibit output to. That is, this can be executed by the judgment function of the microprocessor 101.

Therefore, according to this invention, holidays can be specified for each load. Therefore, the load that is desired to be operated can be operated as usual even on holidays.

Furthermore, in this invention, the memory in the holiday storage means 304 is stored in the timekeeping means 1 when the designated day of the week has passed.
It can be configured to be reset by the carry signal of 03. With this configuration, all loads are automatically returned to a normal state after a holiday, and it is possible to avoid an inconvenience in which a necessary time signal operation is not executed during normal work.

<Effect of the invention> Therefore, according to this invention, by the additional mark, 1
Even if the program has a length that cannot be stored on one card, the storage means 10 stores it as a program with the same load.
4 can be stored. In addition, the output switch controlled by the readout output controls the switch associated with the load according to the load specification attached to the program, so multiple switches can be connected in parallel to control one load. You don't have to do anything to make it work. Yotsute output switch
It is possible to control the number of loads corresponding to the number of SA to SF.

Furthermore, with this invention, holidays can be specified for each load. Therefore, even if there is a load that should be operated normally even on holidays, it can be operated independently on holidays. Furthermore, since the holiday memory can be configured to be automatically reset after the holiday has passed, all loads can be operated in a normal state after the holiday. Therefore, it is possible to provide a program timer that is easy to handle.
