Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operation control timer that is provided to devices such as home appliances and controls the operation of the device over time.

[Conventional technology]

BACKGROUND ART Conventionally, an operation control timer that is provided in a device such as a home appliance and that temporally controls the operation of the device is equipped with a microcomputer (hereinafter referred to as a microcomputer).

When the user of the device inputs the timer-on time, timer-off time, and timer-off time data by operating the key matrix, the above-mentioned microcontroller inputs the current time data and the above-mentioned timer-on time using the built-in clock function. , and the data of the timer off time, and if the data of the current time and the data of the timer on time match, the microcomputer's output port 0N-OUT is set to "H". level to set the device to power-on mode, and if the current time data and timer off time data match, 0N-OU
T is set to the "L" level to put the device into a power-off mode that stops its operation.

In addition, the operation process of the device using the operation control timer is as follows:
As shown in FIG. 5, first, when the timer on time is set (521), the timer standby mode is automatically entered (S22), and then it is determined whether or not the timer off time is set (S23).

And if you have the above timer off time setting,
Next, the current time data and the timer on time data are compared (324), and if the current time data and the timer on time data do not match, the current time is continued to be counted up (S25). On the other hand, if the current time data and the timer-on time data match, the microcomputer's 0N-OUT automatically goes to "H" level, enters the power-on mode (326), and starts operating the device. be done.

Thereafter, the current time data and the timer off time data are compared (S27), and if the current time data and the timer off time data do not match, the current time is continued to be counted up (328). On the other hand, if the current time data and the timer off time data match, the 0N-OUT of the microcomputer automatically goes to the "L" level, entering the power off mode (S29) and stopping the operation of the device. be done.

On the other hand, it is determined whether the timer off time is set (S2
3) If the timer off time is not set, then the current time data and the timer on time data are compared (S30), and if the current time data and the timer on time data do not match, Then, the current time is counted up (S31). On the other hand, if the current time data and the timer-on time data match, the microcomputer's 0N-OUT automatically goes to the "'H" level, entering the power-on mode (S32), and the device stops operating. will be started.

[Problem to be solved by the invention]

However, in the above conventional configuration, if the user of the device forgets to operate the device and sets only the timer-on time to start the device's operation but does not set the timer-off time to stop the device's operation, As shown in Figure 6, the microcomputer's 0N-OUT automatically changes from the "L" level to the "H" level when the timer-on time arrives, and while the device starts operating, the timer-off time is set. Therefore, the power-on mode continues, and the device continues to operate, resulting in the problem of wasted power consumption.

[Means to solve the problem]

In order to solve the above problems, an operation control timer according to the present invention includes a clock means for measuring time, and an operation start signal when the time measured by the clock means reaches a preset timer on time. The operation control timer is provided with an operation control signal output means that outputs a stop signal when the time measured by the timer reaches a preset timer off time, and the following measures are taken.

In other words, when only the timer on time is set,
A stop signal output means for when no off time is set is further provided for controlling to output the stop signal after a predetermined time has elapsed from the timer on time.

[For production]

According to the above configuration, even if only the timer on time is set and the timer off time is not set, for example, the time a predetermined time after the timer on time is automatically set as the timer off time. By doing so, a stop signal is output at that time and the operation is stopped. As a result, wasted power consumption can be suppressed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in FIG. 1, the operation control timer according to this embodiment includes a microcomputer 1 for temporally controlling the operation of the device, and a display for displaying timer on time, timer off time, and current time. 2, a key matrix 3 for inputting data of timer on time and timer off time, and a power switching circuit 4 for switching supply/cutoff of power to various constituent members.

The microcomputer 1 has a clock function, constantly holds data on the current time, and stores data on the timer on time and timer off time inputted from the key matrix 3 in a built-in RAM, and The time data and the current time data are compared, and when the timer on time data and the current time data match, the microcomputer 1 outputs the output port 0N-OUTla.
outputs an operation start signal. That is, 0N-OUTla
Change the voltage level from the previous 'L' level to the '°H' level. On the other hand, compare the data at the timer off time and the data at the current time, and compare the data at the timer off time and the data at the current time. When they match, the microcomputer 1 outputs a stop signal to the 0NOIJT 1a.In other words, the voltage level of 0N-OUTla is changed from the "H" level to the "L" level. As mentioned above, the microcomputer 1 is configured to include a clock means and an operation control signal output means.

Furthermore, if only the timer-on time data is input from the key matrix 3 to the microcomputer 1, the microcomputer 1 will return 0N after 2 hours have elapsed from the timer-on time.
-OUTla, output a stop signal, 0N-OUTl
a is set to the "L" level.

The above-mentioned time after 2 hours has elapsed from the time when the timer is turned on was set based on the statistics that the user of the device uses the device for boat fishing for about 2 hours. The time is not limited to the above two hours, and for example, the timer off time may be automatically set to a time one hour after the timer on time.

The display unit 2 always inputs the current time data from the microcomputer 1 and displays the current time, while each time the microcomputer 1 inputs the timer on time and timer off time data from the key matrix 3. , the timer on time and timer off time data are input from the microcomputer 1, and the timer on time and timer off time are displayed.

The key matrix 3 is equipped with a key switch (not shown), and the user of the device repeatedly operates this key switch to set the timer on time and timer off time, and the data of these times are sent to the microcomputer. It is designed to output to 1.

The power switching circuit 4 includes transistors Q1 and Q
2, and resistors R1-R2 and R3. One end of the resistor R2 is connected to the 0N-OU of the microcomputer 1 mentioned above.
while the other end of resistor R2 is connected to n
It is connected to the base of pn type transistor Q2,
The other end of a resistor R3 whose one end is grounded is connected to the connection point between the resistor R2 and the transistor Q2. The emitter of the transistor Q2 is grounded, and the collector is connected to the base of the pnp transistor Q1 via a resistor R1. The emitter of the transistor Q1 is connected to the output terminal of the DC power supply 5, and the collector is connected to each IC which is a variety of constituent members (not shown). Note that the GND terminal of the DC power supply 5 is grounded.

Then, when the 0N-OUTla of the microcomputer 1 becomes "H" level, the power switching circuit 4 switches the 0N-OUT1a of the microcomputer 1 to the "H" level.
When current flows into the base of the transistor Q2 from UTla, the transistor Q2 is turned on, and accordingly, the transistor Q1 is turned on, and the DC power supply 5 is turned on.
The power source is supplied to various ICs.

On the other hand, the power switching circuit 4 is connected to the 0
When N-OUTla becomes “L level, 0N-OUTl
By stopping the flow of current from a to the base of the transistor Q2, the transistor Q2 is turned off, and accordingly, the transistor Q1 is turned off, thereby stopping the supply of power from the DC power supply 5 to the various ICs. It is designed to be blocked.

In the above configuration, the operation control process of the device using the operation control timer will be described below.

The operation control process of the device is as shown in FIG. -OUTla is at "L" level.

Next, it is determined whether the timer off time is set (S
3).

And if you have the above timer off time setting,
Next, the current time data and the timer on time data are compared (S4), and if the current time data and the timer on time data do not match, the current time continues to be counted up (S5). . On the other hand, if the current time data and the timer on time data match, 0N-OUTla of microcomputer 1 is automatically set to "H".
By reaching the level, a power-on mode is entered in which power is supplied from the DC power supply 5 to various ICs (S6), and the operation of the device is started.

Thereafter, the current time data and the timer off time data are compared (S7), and if the current time data and the timer off time data do not match, the current time is continued to be counted up (S8). On the other hand, if the current time data and the timer off time data match, 0N-OUTla of the microcomputer 1 automatically goes to "L" level, thereby stopping the supply of power from the DC power supply 5 to various ICs. The power off mode is entered (S9), and the operation of the device is stopped.

On the other hand, it is determined whether the timer off time is set (S
3) If the above timer off time is not set, then the current time data and timer on time data are compared (SIO), and the current time data and timer on time data do not match. If so, the current time continues to be counted up (Sll). On the other hand, if the current time data and the timer-on time data match, 0N-OUTla of the microcomputer 1 automatically becomes "H" level, and power is supplied from the DC power supply 5 to various ICs. The device enters the power-on mode (S12) and starts operating the device.

After that, the data of the current time and the data of the time 2 hours after the timer on time are compared (S13), and if the data of the current time and the data of the time 2 hours after the timer on time do not match. , the current time continues to be counted up (S14). On the other hand, if the current time data and the time data 2 hours after the timer on time match, the 0N-OU of microcomputer 1 is automatically counted up.
When Tla becomes "L" level, a power-off mode is entered in which the supply of power from the DCii source 5 to various ICs is cut off (315), and the operation of the device is stopped.

As described above, in the operation control timer according to the present invention, when the timer on time and timer off time are set by the user of the device, as shown in FIG. During this time, ON-OUTla of the microcomputer 1 is set to "H" level to enter the power-on mode, and the device is operated within this time.

On the other hand, even if only the timer-on time is set, the time 2 hours after the timer-on time is automatically set as the timer-off time, so that the timer is turned off as shown in Figure 4. 0N-OUTla of the microcontroller l, which was at the "H" level at the time of the timer on, is automatically set to the "'L" level two hours after the timer is turned on, thereby stopping the operation of the device. There is.

In the above embodiment, when the timer off time is not set by SIO to 315 in FIG.
Although the off-time non-setting stop signal output means 10 for automatically outputting a stop signal has been configured, other means may also be used.

〔Effect of the invention〕

As described above, the operation control timer according to the present invention is configured to output the stop signal after a predetermined period of time has elapsed from the timer on time when only the timer on time is set, when the off time is not set. This configuration further includes a stop signal output means.

As a result, even if the user forgets to operate the device and sets only the timer on time and does not set the timer off time, the time after the timer on time is automatically set. Since it is set as the timer off time, the device can be automatically stopped when a predetermined period of time has elapsed from the timer on time, thereby ensuring that the device operates without wasting power. This has the effect that it can be stopped.
