There is a desire in the market to set a target trajectory of change when the temperature in the test chamber is changed. For example, there is a demand for the temperature in the test chamber to reach from 20 degrees Celsius, which is the starting temperature, to 80 degrees Celsius, which is the high temperature environment, over 10 minutes. In other words, you may want to draw a specific temperature change curve to reach the target temperature from the start temperature.
Therefore, the applicant has prototyped an environmental test apparatus capable of setting the time required to reach the target temperature. The prototype environmental test device has an input device, and the user inputs the final reached temperature of 80 degrees Celsius and the time required for the rise (10 minutes) to the input device. As a result, the temperature in the laboratory reaches the target of 80 degrees Celsius over a period of 10 minutes from the initial 20 degrees Celsius.

Here, the test conditions when using the environmental test equipment are different. For example, when it is desired to reach the temperature in the test chamber from the starting temperature of 20 degrees Celsius to the high temperature environment of 80 degrees Celsius at a temperature change rate of 5 degrees / minute. There is also.
In such a case, the operator using the above-mentioned environmental test device divides the temperature difference by the temperature rise rate, calculates the time to reach 20 degrees Celsius to 80 degrees Celsius, and inputs the time to the input device. Will be done. According to the above example, the temperature difference is "80 degrees-20 degrees = 60 degrees", so the time required for the temperature rise is "60 degrees / 5 degrees = 12 (minutes)". Therefore, the operator inputs the final reached temperature of 80 degrees Celsius and the time required for the rise (12 minutes) obtained by calculation to the above-mentioned input device. As a result, the temperature in the test chamber rises from 20 degrees Celsius to 5 degrees Celsius / min and reaches 80 degrees Celsius after 12 minutes.

According to the prototype environmental test apparatus, the operator can calculate the time required for the temperature change, and by inputting the time, the temperature change rate can be substantially set.
However, there was an opinion that it is troublesome to calculate the time required for temperature change based on the temperature change rate, and it should be improved.

The first object of the related invention of the present invention is to develop an environmental test apparatus capable of directly setting the rate of change of the environment.

For the purpose of solving the above-mentioned problems, the present inventors have changed the program of the control device and improved it so that the temperature change rate can be directly input.
In the improved environmental test device, the final reached temperature of 80 degrees Celsius and the desired temperature change rate (for example, 5 degrees / minute) are input to the input device. As a result, the temperature in the test chamber rises at a temperature rise rate of 20 to 5 degrees Celsius / min. As a result, the temperature in the test chamber reaches the target temperature of 80 degrees Celsius after 12 minutes.

In the improved environmental test device, when it is desired to change the temperature from the current temperature of the test room to the target temperature over a certain period of time, the set temperature and the required time are input to the input device. On the other hand, when it is desired to change the temperature from the current temperature of the test room to the target temperature at a constant temperature change rate, the set temperature and the temperature change rate are input to the input device.
However, according to this input method, there is a concern that the operator inputs all three items of the target temperature, the required time, and the temperature change rate.

Here, when the operator wants to reach the target temperature from 20 degrees Celsius to 80 degrees Celsius at a temperature change rate of 5 degrees / minute, the operator sets the target temperature at 80 degrees Celsius, the required time is 12 minutes, and the temperature changes. If you enter 5 degrees Celsius as the rate, the environmental test equipment operates as the operator wants, the temperature in the test room rises at a rate of 5 degrees Celsius / minute, and after 12 minutes the target temperature is Celsius. Reach 80 degrees.

However, if the target temperature is mistakenly set to 100 degrees Celsius and the error is noticed and corrected to 80 degrees Celsius, the temperature change rate or the required time must be corrected at the same time. Only the input person knows which one to input, and if it is not corrected, it may become inoperable. Further, if the control device has a recalculation function or a function of applying an approximate expression, there is a possibility that the temperature in the test room may change by drawing an unexpected temperature locus by the operator.
In addition, the work of checking whether the input is correct is troublesome, and the worker may feel psychological stress because he / she is worried that there may be an error.

A second object of the related invention of the present invention is to provide an environmental test apparatus capable of directly setting the rate of change of the environment and less likely to cause an input error.

In this case, it is provided to provide an environmental test device, a control device for an environment forming device, a computer program for the environment forming device, and a heat treatment device having a configuration in which the rate of change regarding the amount of change in the environmental factor per unit time is calculated and displayed.

Hereinafter, embodiments of the present invention will be further described.
The basic configuration of the environmental test apparatus 1 of the present embodiment is as shown in FIG. 1, and has a heat insulating tank 3 formed of a heat insulating wall 2. A test chamber 5 is formed in a part of the heat insulating tank 3. The test room 5 is a space in which the test object 18 is installed.
The environmental test device 1 further includes an air conditioner (environmental adjustment device) 17 and a blower 10. The air conditioner 17 is composed of a humidifying device 6, a cooling device 7, and a heating device 8.

The environmental test apparatus 1 has an air-conditioning ventilation passage 15 that communicates with the test chamber 5 in a ring shape, and the air-conditioning equipment 17 and the blower 10 described above are built in the air-conditioning ventilation passage 15.

The air-conditioning ventilation passage 15 is formed in a part of the heat insulating tank 3 and communicates with the test chamber 5 at two locations, an air blowing portion 16 and an air introducing portion 25.
Therefore, when the blower 10 is started, the air in the test chamber 5 is introduced into the air-conditioned ventilation passage 15 from the air introduction unit 25. Then, the air-conditioning ventilation passage 15 is in a ventilation state, air comes into contact with the air-conditioning equipment 17, heat exchange and humidity adjustment are performed, and the adjusted air is blown out from the air blowing portion 16 into the test chamber 5.
Further, a temperature sensor 12 and a humidity sensor 13 are provided in the vicinity of the air blowing portion 16 of the air conditioning ventilation passage 15.
The signals of the temperature sensor 12 and the humidity sensor 13 are input to the control device (control device for environment forming device) 30. Then, the control device 30 compares the detected values of the temperature sensor 12 and the humidity sensor 13 with each set value.
When using the environmental test device 1, the blower 10 is operated to bring the air-conditioned ventilation passage 15 into a ventilation state, and the air-conditioning is performed so that the detected values of the temperature sensor 12 and the humidity sensor 13 approach the temperature and humidity of the set environment. Control the device 17.

That is, by operating the blower 10, the air in the test chamber 5 is introduced into the air-conditioning ventilation passage 15 from the air introduction unit 25, passes through the air-conditioning equipment 17 in the air-conditioning ventilation passage 15, and the temperature and humidity are adjusted. Then, the air whose temperature and humidity have been adjusted is returned from the air blowing unit 16 to the test chamber 5, and an environment of a desired temperature and humidity is created in the test chamber 5.

The environmental test apparatus 1 of the present embodiment artificially creates an environment in which the temperature changes in the test chamber 5, and applies stress to the test object 18 due to environmental factors such as heat in this environment, and the test object 18 is subjected to stress. Changes can be observed.

In the environmental test apparatus 1 of the present embodiment, it is possible to set a target locus of change when the temperature in the test chamber 5 is changed. That is, in the environmental test apparatus 1 of the present embodiment, the locus of temperature change in the test chamber 5 can be set as one of the test conditions.

The test conditions are input to the control device (control device for environment forming device) 30. Further, the control device 30 stores a computer program 60 for an environment forming device for controlling the air conditioner 17 to draw and change a set temperature profile of the environment in the test room 5.

This configuration will be described below.
In the environmental test apparatus 1 of the present embodiment, the temperature environment in the test chamber 5 can be set, and the set temperature, elevating conditions, maintenance time, and the like are switched for each step.
The target locus (profile) of the temperature change is not limited, but will be described as an example in which the set temperature, the gradient setting of the temperature change, and the set time are changed under the conditions shown in Table 1. In the example, the humidity in the test chamber 5 is not set.

The set temperature immediately after the start of the test is 20 degrees Celsius, and the set temperature is maintained for 5 hours without changing the set temperature (step 1).
After 5 hours, the process proceeds to step 2 and the set temperature is changed to 80 degrees Celsius. From the initial temperature of 20 degrees Celsius to the new target temperature of 80 degrees Celsius, the temperature is raised at a rate of 5 degrees Celsius / minute. When the temperature is raised at a rate of 5 degrees / minute, the time required from the initial temperature of 20 degrees Celsius to the set temperature of 80 degrees Celsius is 12 minutes.

When the temperature in the test chamber 5 reaches 80 degrees Celsius, the process proceeds to step 3, and the set temperature is maintained at 80 degrees Celsius to maintain the environment for 5 hours.
After 5 hours, the process proceeds to step 4, and the set temperature is changed to 20 degrees Celsius. The temperature is lowered at a rate of 5 degrees / minute from the initial temperature (starting temperature) of 80 degrees Celsius to the set temperature of 20 degrees Celsius.

A temperature change curve drawn according to the conditions shown in Table 2 is as shown in FIG. 2 (b).
The differences from the conditions in Table 1 described above are step 2 and step 4. Under the conditions in Table 2, the temperature in the test chamber 5 is changed over a predetermined time.
Since steps 1, 3 and 5 are the same as in Table 1, the description thereof will be omitted.
Under the conditions shown in Table 2, the set temperature is changed to 80 degrees Celsius in step 2. The initial temperature is changed from 20 degrees Celsius to the target temperature of 80 degrees Celsius over a period of 12 minutes. The same applies to step 4, and the temperature is changed from 80 degrees Celsius to 20 degrees Celsius, which is the target temperature, over a period of 12 minutes.

Therefore, in step 2, as shown in FIG. 9A, the number 80 is input to the temperature setting unit 36 for the “temperature setting”.
In step 2, the temperature approaches the set temperature over 12 minutes, so the measure for setting the target trajectory should adopt the change amount / time setting method. "Is selected.

With respect to the change rate input unit 38 with respect to the "change rate", the operation of the keyboard 28 or the like is invalidated, and a numerical value cannot be input.
The timekeeping condition selection unit 42 of the “exposure time control” selects “OFF”. 12 minutes is input to the time setting unit 43.
As described above, the change rate input unit 38 for the "change rate" cannot be input by the keyboard 28 or the like, but when each setting condition is determined, the change rate is automatically calculated and as shown in FIG. 9B. It is displayed on the rate of change input unit 38. Specifically, the display is performed at 5.0 ° C./min. However, the rate of change may not be calculated automatically or may not be displayed.

Next, the input method of step 4 will be described. According to the conditions in Table 2, the conditions in step 4 change the current temperature to 20 degrees Celsius and lower the temperature from the initial temperature of 80 degrees Celsius to the target temperature of 20 degrees Celsius over 12 minutes. ..
Therefore, in step 4, as shown in FIG. 10A, the number 20 is input to the temperature setting unit 36 for the “temperature setting”.
In step 4, the temperature approaches the set temperature over 12 minutes, so the temperature gradient selection unit 37 for "gradient control" should adopt the change amount / time setting method, and the temperature gradient selection unit 37 "yes". Select.

The change rate input unit 38 with respect to the "change rate" cannot input a numerical value because the operation of the keyboard 28 or the like is invalidated.
The timekeeping condition selection unit 42 of the “exposure time control” selects “OFF”. 12 minutes is input to the time setting unit 43.
As described above, the change rate input unit 38 for the "change rate" cannot be input by the keyboard 28 or the like, but when each setting condition is determined, the change rate is automatically calculated and as shown in FIG. 10 (b). It is displayed on the rate of change input unit 38. Specifically, the display is performed at 5.0 ° C./min. Further, the rate of change may not be automatically calculated or the rate of change may not be displayed on the rate of change input unit 38.

In the above-described embodiment, on the setting screen of each step, the change amount / time setting method for setting the change target locus by the combination of the change amount information and the time information, and the change target by the combination of the change amount information and the change rate information. Although the change amount / change rate setting method for setting the locus has been selected, either one may be selected in advance on the initial screen or the like.

For example, when the selection items of "new creation 1" and "new creation 2" are created on the initial screen 44 shown in FIG. 11 and one of them is selected, each step screen is dedicated to the change amount / time setting method, and the other is selected. May be configured to be a method for setting the amount of change and the rate of change.
FIG. 12 shows an example of an input screen when "new creation 1" is selected on the initial screen 44 shown in FIG. 11 and the setting is made based on the change amount / time setting method. On the input screen when setting based on the change amount / time setting method, there is no item name of "change rate" or a change rate input unit for the item name, and "change rate" cannot be input.

When "New creation 2" is selected, the input screen for setting based on the change amount / change rate setting method is displayed. The input screen in this case is the same as the input screen 32 of FIG. Further, as another example, the screen when "New creation 2" is selected may not have columns for setting the amount of change and time, and these settings may not be possible.

According to the embodiment described above, when the target locus of change is set by the change amount / time setting method, the change rate information cannot be input. Further, when the target locus of change is set by the change amount / change rate setting method, it becomes impossible to input the time information. Therefore, it is possible to prevent inconsistent setting conditions from being set, and it is possible to prevent unexpected setting conditions from being set.

In the above-described embodiment, both the target locus of change can be set by the change amount / time setting method and the target locus of change can be set by the change amount / rate setting method. That is, in the above-described embodiment, it is possible to set the target locus of change by using the change rate information regarding the amount of change of the environmental factor per unit time as one of the input information, and to set the time information regarding the time required for the environmental change. It is also possible to set the target trajectory of change as one of the input information.
However, the present invention is not limited to this configuration, and the target locus of change may be set only by the method of setting the amount of change and the rate of change.

The input screens and input procedures shown in FIGS. 3 to 12 are merely examples, and are not limited thereto.
For example, even if "Yes (rate of change)" is selected in the temperature gradient selection unit 37, if "0" is input as the rate of change in the subsequent rate of change input unit 38, time information can be input. May be. In this way, it is possible to set the target locus of change substantially by the change amount / time setting method, and the gradient setting as in steps 1, 3 and 5 of FIG. 2 is not performed. It is also possible to set the condition with the setting of "Yes (rate of change)".

Further, in the above-described embodiment, for example, in step 1 and step 3, the temperature in the test chamber 5 is maintained at a set temperature and held for a certain period of time, but a certain environment is maintained for such a certain time. It may be set not to be used. For example, it is not necessary to set only the polygonal line-shaped setting locus as illustrated in the graph of FIG. 13A, and not to hold the constant environment for a certain period of time.

The graph of FIG. 13A shows a target locus of temperature change when the temperature change gradient is changed for each step and the temperature is set to rise or fall in a plurality of steps.

Further, as shown in FIG. 13B, the same rate of change may be set in successive steps, and the environment may be changed at the same rate of change while the continuous steps are executed.
Of course, in one step, the target trajectory of change is set by the change amount / time setting method, and in any of the steps before and after, the target trajectory of change is set by the change amount / change rate setting method, and as a result, the change is continuous. In the steps, the environment may change at the same rate of change.

The environmental test apparatus 1 described above has an air conditioner 17 as an environmental adjustment device, and can set a target locus of temperature change in the test chamber 5.

The environment adjustment device is not limited to the mere air conditioning device 17, and may have other additional environment change functions. Furthermore, it may not have an air conditioning function and may have another environment changing function.

For example, in addition to the above configuration, the air conditioner 17 as an environmental adjustment device can also set a target locus of humidity change in the test chamber 5, and the target locus can also be set as a change amount / time setting method. The change amount / change rate setting method may be selectable. When the target trajectory of humidity change is set by the change amount / time setting method, it becomes impossible to input the humidity change rate. In addition, when the target trajectory of humidity change is set by the change amount / change rate setting method, time information cannot be input.
Further, the present invention can be applied to an environmental test apparatus capable of setting a target locus of pressure change.
For example, an environmental test device that has a closed test room and can keep the air pressure in the test room constant, and can set the time from the current pressure to the target pressure and the rate of change. The present invention can also be applied to.

The environment adjusting device includes a device that applies a voltage or a current to the test object 18, a device that irradiates the test object 18 with light rays or radiation, a device that forms a magnetic field, etc., and has an intensity, frequency, etc. of these.
