Description

[Detailed Description of the Invention] A storage device storing predetermined data such as predetermined time data and predetermined control data during the unit of time, a clock device, and the time data in the storage device. and a coincidence detection circuit with time data in a clock device,
The present invention relates to an improvement of a program timer device in which a predetermined control data output paired with time data is obtained by the coincidence detection force from the coincidence detection circuit described above.

When the time length of a predetermined unit of time is 24 hours, the program timer device described above is configured to time the program at at least one predetermined time within the 24-hour period (one day). The operation of sending predetermined control data is repeated every 244 hours, and the length of the predetermined unit of time is 168 hours (1
In the case of a weekly program timer, it is a so-called weekly program timer device, and depending on how the unit time length is set, it can be configured as a so-called monthly program timer device or an annual program timer device.

By the way, when using the program timer device as described above, it may be necessary to perform a predetermined program transfer to operate the device. This point will be explained below using a specific example of a school broadcast using a weekly program timer device.

In other words, when a school broadcast is performed using a weekly program timer device, the normal operation mode is to broadcast the school broadcast for each day of the week according to the program for each day of the week from Sunday to Saturday that is preset in the weekly program timer device. For example, if Wednesday is a holiday, Wednesday is moved to Sunday, which is a holiday, and the day of the week is changed so that Sunday's program is executed on Wednesday. Transfers may occur.

The method of changing the days of the week that has traditionally been carried out in weekly program timer devices is to transfer one or more of the seven days of the week from Sunday to Saturday to one of the other seven days of the week. However, this type of rescheduling would not be able to handle cases where school broadcasts had to be broadcast on a completely different schedule than usual, such as during the opening ceremony. In the above cases, the conventional method is to stop the control by the program timer device and prevent broadcasting at all, or to leave the program timer device to continue broadcasting as programmed. One of the methods used was to keep it in place.

In the present invention, a predetermined time is used as a unit of time, and predetermined data such as predetermined time data in the unit of time and predetermined control data paired with the predetermined time data are stored. The device includes a storage device, a clock device, and a coincidence detection circuit between the time data in the storage device and the time data in the clock device, and the time data output is obtained by the coincidence detection circuit from the coincidence detection circuit. In a program timer device which is designed to be used as a clock device, specific data other than the above-mentioned predetermined data is stored in the storage device, and time designation data is input to the program timer device from a source other than the above-described clock device. A boogram timer device is provided with input means so that control data for specific data other than the above-mentioned predetermined data is output when the above-described time designation data is input to the program timer device. hand,
This solves the conventional problems mentioned above, and is as follows:
The Boogram timer device of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of an embodiment in which the program timer device of the present invention is implemented as a weekly boogram timer device. In FIG. 1, TA is a clock device, M is a storage device, and B1 is a day of the week. Buffer, B2 is time buffer, G
is an output gate, SW is a changeover switch, Bo is an output buffer, C1 is a day of the week comparator, C2 is a time comparator,
” C3 is a comparator for the transfer designated day of the week, Rd is a register for the designated data of the day of the week on which transfer is to be performed (hereinafter, it may be abbreviated as register Rd and listed in 81), Rp
is a register of specified data for a specific day of the week (hereinafter referred to as register R)
(sometimes abbreviated as p).

The clock device TA generates time data in the form of a combination of time data of the current time and time data in the form of data of the current day of the week, and stores the time data of the current time in the register Rt.
, to the fixed contact of the time comparator t3 and the changeover switch SW via the line t, and to the day of the week comparator CI via the movable contact a and the line t4.

The storage device M stores a required number N of predetermined time data (predetermined time data based on a combination of day of the week data and time data) and predetermined control data paired with the predetermined time data. The day of the week data stored in the storage device M is supplied to the day of the week comparator C1 via the line t, the day of the week buffer B1 and the line t6, and is also stored in the storage device M. Time data is provided to the time comparator C2 via line t7 and time buffer B2 and line t8, and control data stored in memory M is provided to output gate G via line t. It's okay.

When the movable contact a of the changeover switch SW is switched to the fixed contact side, the current day of the week data in the register Rt2 in the clock device TA matches the day of the week data in the storage device M, and , when the current time data in the register Rt of the clock device TA matches the time data in the storage device M, the output gate G is opened by the match detection force from the day of the week comparator C1 and the time comparator C2. The control data in the memory M is on the line t, and the output gate G and the line t,. Output buffer B via.

and the output buffer B. Control data will be output from.

The operation of the program timer device as described above in a state where the movable contact a of the changeover switch SW is connected to the fixed contact side is similar to the operation of a conventional program timer device, but the program timer device of the present invention Then, the data in the register Rd, which is the designation data for the day of the week on which the transfer is to be made, is sent to the comparator C for the designated day of the week via the line t11.
3, and when the data in the register Rd and the data on the current day of the week in the clock device TA match, the match detection force output from the comparator C3 on the transfer designated day causes the changeover switch SW to be turned on. The movable contact a'r is switched to the fixed contact C side, and the data in the register Rp specifying the specific day of the week is sent to the day of the week comparator CI via the line t12, the fixed contact C and movable contact a of the changeover switch sw, and the line t4. Therefore, on the day of the week designated for register cleaning, the day of the week stored in the register Rp is given to the day of the week comparator CI, and therefore the register Rd is On the designated day of the week, the program for the specific day stored in the register Rp will be output from the output buffer Bo.

Data on the days of the week on which transfers are to be made out of the seven days of the week from Sunday to Saturday is input and stored in advance in the register, but the number of days of the week to be stored is not limited to one. There may be any number. Also, register Rp
Data specifying a specific day of the week is entered and stored in advance, but in the device of the present invention, one of the seven days of the week from Sunday to Saturday can be specified as a specific day of the week, or data specifying a specific day of the week can be specified as a specific day of the week. A day of the week other than work day L-1, that is, a transfer-only day that does not exist in the calendar, is designated as a specific day of the week, and its data is input into the register Rp and stored.

For example, if you want to transfer Monday, Wednesday, and Friday to a special day of the week, enter and store data specifying Monday, Wednesday, and Friday in register Rd, and register Rp.
The data specifying a specific day of the week is entered and stored in the register, and if the data is stored in the registers Rd and Rp as described above, the data for each day of the week (Monday, Wednesday, Friday) , control data for a specific day of the week specified in register Rp is output from the storage device through output gate G, and then output buffer B. It is output from.

A new day of the week other than the 7th day of the week, that is, the transfer-only day described above, is provided as a specific day specified by the register Rp, and the data stored in the storage device MK is configured to include data corresponding to the transfer-only day of the week. Even if the specific day of the week specified in the register Rp is a transfer-only day, each day of the week specified in the register Rp has S stored in the storage device M in advance in correspondence with the transfer-only day. It is clear that the program that I had memorized will be executed.

Therefore, it is possible to store data specifying the transfer-only day of the week in the register Rp, and to store predetermined data corresponding to the transfer-only day of the week in the storage device M. Conventional problems can be solved satisfactorily.

When the program timer device of the present invention is implemented as a weekly boot gram timer device, the data indicating the day of the week can be a 3-digit (3-bit) binary code as shown in the following table.

(Table 1) However, the day of the week data in the storage device M, the clock device TA
The day of the week data in the register Rt2, the specific day data in the register Rp, the day of the week data set in the y register Rd, etc., do not use the codes that indicate the day of the week as shown in Table 1 above, but instead indicate the day of the week. As a code, 8
Alternatively, the day of the week data stored in the storage device M, the day of the week data in the register Rt2 of the clock device TA, and the day of the week data set in the register Rp using binary numbers of digits are as follows: Using the codes shown in Table 1, and using the codes shown in Table 2 as the day of the week data to be set in the register,
The day of the week data in the register Rt2 of the clock device TA is sent to the second register via the decoder.
The day of the week data may be given to the comparator C3 for the transfer designated day as a code according to the table. In this case, when there are multiple days of the week on which transfer is to be made, the day of the week data may be given to the register Rd in the form of a simple code. can be input.

In other words, 1. If the day of the week on which the transfer is to be made is, for example, a month,
If it is Wednesday and Friday, the data to be input to the register sweep will be 00101010, and if the days of the week to be transferred are, for example, ms day of the week and Tuesday, the data to be input to the register Rd will be -0000011.
The code form is simplified such that 0 becomes 0, and the 2
It consists of 8 AND circuits that take the logical product of the signals of the corresponding digits of the 8-digit code, and one OR circuit that takes the logical sum of the outputs from the 8 AND circuits. A simple configuration can be used.

Figure 2 uses the code shown in Table 1 to indicate the day of the week, and as a register,
The high level voltage is transferred from the power supply E to the switch SW by the switch S operated on the day when the transfer is to be carried out.
FIG. 2 is a block diagram showing an embodiment of the program timer device of the present invention using a device having a configuration that can be given as a switching control signal; ing.

In Fig. 2, NAND circuit N, ~N0, inverter IN
A multiplexer composed of NOR circuits NOR, -NOR3, etc. is a component corresponding to the changeover switch indicated by SW in FIG.

When the switch S in the resistor Rd is off, the output of the resistor Rd is at a low level due to the grounding by the resistor R, the gates of the NAND circuits N, ~N3 are closed, and the low level state of the resistor Rd in this state is set to a high level by the inverter INV and is supplied to the NAND circuits N, ~N6 as individual power, so that the data in the register Rt2 in the clock device TA is input to the NAND circuits N4 to N6, the NOR circuits NOR, ~NOR3, and the line t4. The data is supplied to the day of the week comparator C1 via the data.

Furthermore, when the switch S on the register board is on, the output of the resistor Rd is at a high level and the gates of the NAND circuits N4 to N are closed. The day of the week data of is given to the NOR circuits NOR, ~NOR3h, so the day of the week data of the register Rp is supplied to the day of the week comparator CI via the line t4, and corresponds to the transfer-only day that has not been set in the register Rp. The predetermined control data is changed to cover sofa B. will be output from. Note that register Rp,
The stomach in Rt2 etc. is a Frisopf ρ tube.
