Abstract

PROBLEM TO BE SOLVED: To provide a simplified program controller with which a program pattern of the unit of 24 hours can be executed continuously for several days and the controller itself can be switched/returned to a standby mode without connecting any external timer or sequencer. SOLUTION: This temperature controller is composed of a setting part 41 having a setting function for the program pattern of the unit of 24 hours, storage part 42 for storing this program pattern, time measuring part 43 having a clock function, and arithmetic processing part 44. Then, the arithmetic processing part 44 repeats the execution of prescribed control operation just certain times preset from an input signal 3, the program pattern from the storage part 42 and time from the time measuring part 43 and outputs the result.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for receiving a signal from a temperature sensor such as a resistance temperature detector or a thermocouple as an input, and outputting a heat medium according to an output signal such as a relay, a voltage pulse or a current according to a preset program pattern. And a program temperature controller for controlling the temperature of the control target to a predetermined value.

[0002]

2. Description of the Related Art Conventionally, in order to set a temperature in units of 24 hours, and to repeatedly execute this for several days, or to switch / return to the standby mode of the controller itself,
A control system was configured by connecting another timer or sequencer outside the program temperature controller.

[0003]

In the conventional apparatus, 24
In order to set the program pattern in time units and switch / return to the standby mode of the controller itself,
An external timer was required for the programmed temperature controller.
In addition, in order to execute a program pattern in a unit of 24 hours in the same pattern continuously for several days, it becomes a system out of a simple area such as adding another device or a system using a sequencer, etc. Installation space and the like increased, and could not be easily realized.

An object of the present invention is to provide a simple program temperature controller which can easily realize the above functions.

[0005]

In order to solve the above-mentioned problems, in the present invention, the temperature of a control target is controlled by performing a predetermined control operation on an input signal from a temperature sensor to control a heating medium. A setting unit having a function of setting a program pattern in units of 24 hours, a storage unit having a function of storing the set program pattern, a clock unit having a clock function, and an input signal. An arithmetic processing unit having a function of repeating a predetermined control operation from a program pattern from the storage unit and a time from the clock unit for a preset number of times and outputting the result is provided.

Further, in addition to the above, the setting section has a function of setting a standby mode in a program pattern, and the arithmetic processing section has a function of setting the simple program temperature controller in the standby mode by the standby mode. did.

FIG. 1 is a block diagram for explaining an embodiment of the present invention. In FIG. 1, 1 is a control target, 2 is a temperature sensor, 3 is an input signal, 4 is a simple program temperature controller, 5 is an output signal, 6 is a heating medium, 41 is a setting unit, 42 is a storage unit, and 43 is timekeeping. The unit 44 is an arithmetic processing unit.

The setting unit 41 has a function of setting a program pattern in units of 24 hours.
2 The arithmetic processing unit 44 performs a predetermined control operation based on the input signal 3 from the temperature sensor 2, the pattern from the storage unit 42, and the time from the clock unit 43, outputs an output signal 5, and controls via the heat medium 6. The temperature of the object 1 is controlled. Therefore, the simple program temperature controller 4 is managed in units of 24 hours. By adding a pattern repetition function to the control calculation unit 44, the number of days in which one pattern becomes one day and the user wants to operate repeatedly is set as the number of patterns, thereby enabling the repetitive operation for several days to several months.

Switching to a standby mode (a state in which display and output of the controller are turned off and control is not performed) is performed by:
For example, when there is a time period during which it is desired to stop the device during the day, the setting pattern 41 is provided with a function that can be set to switch to the standby mode and a function that can be set to return from the standby mode to the normal operation mode. Keep it. When detecting this, the control calculation unit 44 switches the controller to the standby mode only during that time zone.

[0010]

According to the present invention, a timer or a sequencer, which is conventionally provided externally, becomes unnecessary, so that it is possible to increase economical effects and to save space.
