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, air conditioning equipment, etc. There is.

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

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 reading this code with 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 optically, for example, 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 in the symbol corresponding to the load with black, for example, with a pencil or the like. 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. That is, the first column of the time entry field 201 represents the 10th digit of the hour, and the second column represents the 1st digit of the hour. The third column represents the value of the 10th digit of the minute, and the fourth column represents the value of the 1st digit of the minute. 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 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.

When one load is controlled by a program distributed over multiple storage areas, for example B and C, output switches SB corresponding to areas B and C are used.
and SC are connected in parallel, and one load is controlled by the contact outputs of output switches SB and SC connected in parallel. 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,
Since the storage area cannot be used for storing programs of other loads, the storage means 104
There is a drawback that it cannot be used effectively.

<Purpose of the invention> This invention aims to provide a card-type program timer that can store even long programs for the same 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 additional information is written on the card. Set up a column,
By adding an addition mark to this addition entry column and inputting it, any program can be added to the programs that have already been input.

Therefore, according to this invention, since storage areas are not designated for each load, even a long program for one load can be stored.

<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 or not the program written in the load description column 202a input from 05 already exists in the storage means 104; and the storage means 104
Load 30 for detecting addresses in a free state
2, and an additional entry column 4 shown in FIG. 4 on the card 106.
Means 303 for detecting that 01 has been provided and that an additional mark has been added to this additional entry field 401
It is characterized by the following.

<Description of operation of the invention> If the input card does not have an additional mark attached, the determining means 301 determines whether the program in the load description column 202a attached to the card already exists in the storage means 104. do. Storage means 1
If no program related to the load is stored in 04, the programs of the cards inputted in order from the highest address of the free area are stored.

Therefore, in the initial state, by creating a card for each load and 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 are input, starting from the first address. It should be noted 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 by 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 is placed in the additional entry field 401 of the second card (the inside of "" in the additional entry field 401 is painted black). , write the program following the first card on the card with the additional mark, and insert this 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 clock means 103 by the read operation, and if the current time and the set time and day of the week match, the program is read out according to the load information attached to the program. Output switch SA corresponding to load
~ SF is operated on or off to control the load.

<Effects of the invention> Therefore, according to this invention, even a program whose length cannot be stored on one card due to additional marks can be stored in the storage means 104 as a program with the same load. 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. Therefore, it is possible to control a number of loads corresponding to the number of output switches SA to SF.

Furthermore, even if Monday to Friday is a regular day of work and Saturday is a half-day day of work, according to this invention, the program for Monday to Friday and the program for Saturday can be stored in the storage means 104 as programs with the same load. Since the same output switch can be controlled by the readout output, there is an advantage that even in such a case, it is not necessary to connect the output switches in parallel.
