Abstract

PURPOSE:To facilitate time conversion by providing a converting means which shifts the output of a timepiece by the deviation value of time to conversion start time when the start time of the conversion and the deviation value of time are supplied from a conversion control means. CONSTITUTION:When the timepiece 1 reaches the conversion strat time to, a comparison part 19 outputs a pulse and a switch 23 is set on a solid-line side under the control of an opening/closing control part 22. A subtraction part 10 outputs the difference between the time of the timepiece 1 and the conversion start time t0 of a register 14 and a multiplication part 13 performs multiplication by a multiplier (a) for making the advance of time fast. An addition part 12 adds the time t0 and addition part 13 adds the deviation (d) of the time, and the time to a processing time 4 becomes a(t1+t0)shown by a straight line A, so that the advance of the time is made fast by the deviation (d). Then when the timepiece 1 reaches the end time t1 of the conversion, a comparison part 20 inputs a pulse to a control part 22, which controls the switch part 23 to a dotted-line side, so that the subsequent time of the timepiece 1 is supplied to the processing part 4.

Description

[Detailed Description of the Invention] [Summary] This invention relates to a time conversion device that converts the output of a clock that outputs the elapsed time from a reference time. The purpose of this is to provide a time conversion device that can convert the clock to the time that has not been converted once the conversion is completed, and converts it to the output of a clock that outputs the elapsed time from the reference time start time and end time of conversion. When the conversion start time and the time difference value are given by the conversion control means that gives the time difference value and the multiplier that makes the time advance faster, the output of the clock is changed to the conversion start time by the time difference value. You can make the time go by faster, and if you give a multiplier that makes the time go faster, you can make the time go faster according to that multiplier.
Furthermore, if the end time of the conversion is given, a conversion means is provided that outputs the time of the clock from then on when the clock reaches the end time of the conversion.

[Industrial application field]

The present invention provides time conversion for use in cases where the output of a clock that outputs the elapsed time from a reference time is input, and a processing unit that performs a specified process at a specified time is to be performed quickly and in a short time. Regarding equipment.

When developing a processing unit that performs a process at a specified time, for example 10:00, 11:00, or 12:00, it is necessary to check whether the specified process is performed at the specified time. , even though it is currently 8 o'clock, the time for manual input to the processing section is set to 1.
There is a desire to shorten the time from 10 o'clock to 11 o'clock and 12 o'clock, to perform processing specified as 11 o'clock and 12 o'clock early, and to see the processing results quickly. This was done in response to requests.

[Conventional technology]

FIG. 4 is a block diagram showing the time input from the conventional clock to the processing section.

Conventionally, in order to input the time to the processing unit 4 that performs a specified process at a specified time, as shown in FIG. 4, the output of a clock 1 that indicates the elapsed time from a reference time is input.

Therefore, if the processing unit 4 performs a process specified for example at 1 o'clock, 11 o'clock and 12 o'clock, and the current time is 8 o'clock and you want to see the processing result quickly, change the output of the clock 1 from 8 o'clock to 10 o'clock. The process was started early.

[Problem to be solved by the invention]

However, in the above time conversion method, in order to speed up the process, the output time of clock 1 must be changed, and at the end of the process,
There is a problem that the time must be returned to the correct time, which is time consuming, and a problem that it is not possible to make the time advance faster, for example, to shorten the time from 10:00 to 12:00 to 12:00.

The present invention can smooth the output time from the clock 1 and make the time advance faster with less effort, and once this conversion is completed, the time can be set to the time of the clock 13 4 that has not been converted. The purpose is to provide a time conversion device that can be used.

[Means to solve the problem]

FIG. 1 is a block diagram of the principle of the present invention.

As shown in FIG. 1, the output of the clock 1 which outputs the elapsed time from the reference time includes a conversion start time and a conversion end time. From the conversion control 1,000 stages 2, which gives the value of the time difference and a multiplier to speed up the time, when the start time of conversion and the value of the time difference are given, the output of clock 1 is set to the time difference of the time difference at the conversion start time. You can shift the time by a value, and if you give a multiplier that makes the time advance faster, you can make the time advance faster according to that multiplier.
Further, when the end time of the conversion is given, when the clock 1 reaches the end time of the conversion, a conversion stage 3 is provided which outputs the time of the clock 1 from then on.

[Function] According to the present invention, from the conversion control stage 2, the conversion start time,
When the value of the time shift is given, the output of the clock 1 can be shifted by the value of the time shift to the conversion start time using the conversion control means 2. If a multiplier that speeds up the progression is given, the conversion means 3 can make the time advance faster according to the multiplier, and if the conversion end time is given from the conversion system fff1 means 2, the conversion means In step 3, after the end time, the time of clock 1 is output, so it is easy to shift the time, make the time advance faster, and set the time to the unconverted clock when the time ends. I can do it.

When a pulse is manually input from the comparator 19 to the opening/closing control section 22, the switch 1 is set to the solid line side, and when a pulse is inputted via the switch 24 or 25, the switch I is set to the dotted line side.

The start time t of time conversion is now in register l4. , a multiplier a (a > 1) that makes the time advance faster is stored in the register 15, and a value cl (d > 0) that is the difference from the actual time is stored in the register 16.
, the conversion end time t, is stored in the register 17, the switch 24 is closed, and the switch 2G of the switching control unit 22 is closed, the output time tX of the clock 1 and the input to the processing unit 4 The relationship with time ty will be explained using FIG.

Time 1X of clock 1 is conversion start time t. If it is less than 1, the switch 23 is on the dotted line side, and the input time to the processing unit 4 is the same as the time of the clock 1.

and the conversion start time of register 14. The difference between t and t is output, multiplier 13 multiplies it by a multiplier a that speeds up time, and adder 12 outputs the conversion start time t. is added, and the time difference d is added in the addition unit I3, and the time to the processing unit 4 becomes a (t.-t.) + (to+d), as shown in Figure 3A, and the time is d.
As time progresses, the time becomes faster.

Next, the time of clock l is the end time of conversion 1. Then, a pulse is input from the comparator 20 to the opening/closing control section 22, and the switch 23 is on the dotted line side due to the control C of the opening/closing control section 22.
Thereafter, the time 18 of the clock 1 is given to the processing unit 7 8 .

In addition, when the manual input time to the processing unit 4 reaches t2, if you want to end the conversion, store t2 in the register 18 and turn on the switch 24.
If the switch 25 is closed and the input time to the processing section 4 reaches 12, a pulse is manually inputted from the comparison section 21 to the switching control section 22, and the switch 23 is closed under the control of the switching control section 22. It becomes the dotted line side, and from then on, the time t8 of the clock [ is given to the processing unit 4.
