Description

The present invention relates to a thermocouple sensor, and particularly to a thermocouple sensor device suitable for grasping the replacement timing of the thermocouple sensor.

Conventionally, thermocouple sensors and resistance temperature detectors have been used for temperature control of heating furnaces, silos, freezers, etc. (hereinafter referred to as “measurement target devices”). The thermocouple sensor or the like is connected to a thermocouple sensor device (for example, a graphic recorder; a recorder), and the detection result by the thermocouple sensor or the like is input to the thermocouple sensor device. The thermocouple sensor device outputs information (for example, graph output) indicating a temperature change applied to the device to be measured based on the input detection result and timekeeping information (for example, Patent Document 1).

Since the temperature inside the device to be measured is high, the thermocouple sensor used for this device deteriorates over time. Deterioration of the thermocouple sensor reduces the accuracy of the detection result, making it impossible to accurately grasp the temperature inside the device to be measured. As a result, there is a possibility that the temperature adjustment in the device to be measured may be hindered.

Therefore, there is a thermocouple sensor device that displays the previous replacement date on a display or the like so that the thermocouple sensor is replaced after a predetermined number of days, based on the previous replacement date of the thermocouple sensor. Although it is another technical field, the life of consumable parts is predicted based on the plant operation plan and operation information such as the measurement space of the measurement target device such as a waste incinerator and the measurement space of the measurement target device such as an ash melting furnace. A system for calculating the replacement time has been proposed (for example, Patent Document 2).

<Explanation of Embodiment 1 Configuration>

<Embodiment 1 Thermocouple Sensor>
The "thermocouple sensor" SE is composed of one circuit (thermocouple) in which two metal wires of different materials are connected. When a temperature difference is applied to each contact of the metal wire of the thermocouple sensor SE, a voltage is generated in the circuit. Since the thermocouple sensor SE is arranged inside the measurement target device, the temperature around the first contact arranged inside the measurement target device and, for example, the temperature around the second contact arranged outside the measurement target device. There is a difference. Due to this temperature difference, a voltage is generated in the thermocouple sensor SE. The temperature is measured by measuring this voltage with the device to be measured.

<Embodiment 1 Measurement target device temperature information acquisition unit>

The “measurement target device temperature information acquisition unit” 0101 acquires a voltage signal from the thermocouple sensor SE as measurement target device temperature information. This measurement target device temperature information is used by the measurement target device operation status information display unit 0104 and the thermocouple exchange timing information output unit 0108 for each process described later.

<Embodiment 1 Timekeeping Unit>

The “timekeeping unit” 0103 has a function of acquiring information (timekeeping information) regarding the elapsed time from the start of temperature measurement or the elapsed time from the start of operation of the device to be measured. The timekeeping unit 0103 may acquire the date and time as timekeeping information. Specifically, the timekeeping unit 0103 counts the number of clock pulses output by a transmitter (not shown), and when the count value reaches a reference value, a unit time signal indicating a unit time is generated. The timekeeping unit 0103 generates a date and time used by the main body of the apparatus based on the generated unit time signal. Further, the timekeeping unit 0103 outputs the elapsed time used for displaying the operation status of the measurement target device to the measurement target device operation status information display unit 0104. Further, the elapsed time used for controlling the output of the thermocouple exchange timing is output to the thermocouple exchange timing information output unit 0108. Details of these displays and output controls will be described below.

<Embodiment 1 Measurement target device operation status information display unit>

The “measurement target device operation status information display unit” 0104 performs display processing of the operation status of the measurement target device including the temperature change of the measurement target device. Based on the temperature information of the device to be measured acquired by the temperature information acquisition unit 0101 of the device to be measured and the time information from the time measuring section 0103, information indicating the temperature change of the device to be measured with time as shown in FIG. 2 is created. do. For example, the measurement target device operation status information display unit 0104 converts the voltage signal (measurement target device temperature information) generated in the thermocouple sensor SE into numerical data, and acquires the converted measurement target device temperature information from the measuring unit 0103. Correspond to the timed information. Further, the measurement target device operation status information display unit 0104 creates waveform data for displaying a waveform (for example, FIG. 2) indicating the correspondence of the measurement target device temperature information for each time as a graph. In this case, although the horizontal axis 0210 adopts the time in FIG. 2, it may be configured to display the elapsed time from the time when the input of energy such as electric power is started to the heating source such as the heater instead of the time. good. Further, on the screen of FIG. 2, the heating schedule of the device to be measured or the like is selected, and in the figure, the heater 1 adopts the program 1 and the heater 2 adopts the program 2. Also, according to this schedule, it is shown that the end time is 14:00.

<Example 1 Example of measurement target device operation status information display screen; Supplement>

Specifically, in the display screen of FIG. 2, the time display field 0201, the first temperature display area 0202, the second temperature display area 0203, the temperature change display graph 0204, the temperature change schedule display graph 0205, and the first heater program display area 0206 , A second heater program display area 0207, a start time display area 0208, and an end time display area 0209 are provided.

The time display area 0201 is an area in which the current time based on the current time information acquired by an arbitrary time information acquisition means (not shown) such as the time measuring unit 0103 is displayed. The first temperature display area 0202 and the second temperature display area 0203 indicate the temperature in the measurement space of the current measurement target device such as a furnace heated by the heater, or the temperature of the measurement target object (mold or the like). The first temperature display area 0202 is an area for displaying the temperature of the measurement target device measured by the channel 1 of the thermocouple sensor SE, and the second temperature display area 0203 is the measurement target device measured by the channel 2 of the thermocouple sensor SE. This area displays the temperature. In the following, when the term "temperature in the measurement space of the device to be measured" is referred to, it shall be "the temperature in the measurement space of the device to be measured or the temperature of the object to be measured (mold, etc.)".

The temperature change display graph 0204 is a graph showing the temperature change for each time after the heating start time of the device to be measured. As shown in the figure, the vertical axis indicates the temperature in the measurement space of the device to be measured such as a furnace, and the horizontal axis indicates the time. The temperature change schedule display graph 0205 is a graph display of the prediction of the temperature change after the current time according to the heating program or the heating schedule of the heater that adjusts the temperature of the device to be measured. In order to make it distinguishable from the temperature change display graph 0204, which is a graph display of the temperature change up to the current time, the display mode as shown may be distinguished.

The first heater program display area 0206 and the second heater program display area 0207 are areas for displaying the type of heating program of each heater. The start time display area 0208 is an area for displaying the heating start time in the heating program or heating schedule of the heater. In the end time display area 0209, it is estimated that the measured value of the temperature in the measurement space of the measurement target device such as the furnace for each channel of the thermocouple sensor SE drops to the temperature at the start time in the heating program or heating schedule of the heater. This area displays the time.

<Embodiment 1 Measurement target device operation status information display unit; Supplement_heating schedule input screen>

Further, the measurement target device operation status information display unit 0104 displays a setting screen (not shown) for inputting a heating schedule (FIG. 3 or the like) of the measurement target device. This schedule can be set by calling the predetermined heating schedule program described above, or can be configured so that a new program can be registered in addition to the program registered in advance. The registration of the program can be sequentially created by setting the ultimate temperature in the measurement space of the device to be measured such as a furnace at each time from the start to the end of heating. For example, the temperature rises by 150 ° C. or more from the room temperature “RT” in one hour from the start “9:00” to “10:00” in FIG. At "11:30", the temperature inside the measurement space of the device to be measured such as a furnace is set to 500 ° C, and the temperature to be measured by the furnace etc. is set between "11:30" and "12:00". The temperature in the measurement space of the device is maintained at 500 ° C. Furthermore, between "12:00" and "13:00", the temperature in the measurement space of the device to be measured such as a furnace decreases from 500 ° C to 200 ° C, and from "13:30" to "14:00". In the meantime, the temperature in the measurement space of the device to be measured such as a furnace returns to the room temperature "RT". By repeatedly inputting the elapsed time and the set temperature in this way, a heating schedule is created and configured so that it can be registered as a new program.

The program that displays a graph showing the correspondence of the temperature information of the device to be measured for each time (Fig. 2) and the program that displays the setting screen (not shown) for inputting the operation schedule of the device to be measured (Fig. 3 etc.) are non-volatile. It is stored in the sex memory 0703 (see FIG. 7). “RT” in FIG. 3 indicates room temperature (room temperature before the start of heating). The measurement target device operation status information display unit 0104 displays on the display D based on a program for displaying the measurement target device temperature information and the heating schedule for each hour (measurement target device operation status information display program, etc .; see FIG. 7). The details of the hardware configuration will be described later.

<Setting of exchange timing information output rule>

<Template rule holder>

The “template rule holding unit” 0105 holds a template rule for generating thermocouple exchange timing information. The template rule is completed as a rule for outputting the thermocouple replacement timing by setting the thermocouple life element related to the temperature information of the device to be measured and the time measurement information for each channel of the thermocouple sensor (. It is a template created as shown in FIG. 5). The thermocouple life element is an index in the present embodiment indicating that a load is repeatedly applied to the extent that it affects the replacement of the thermocouple sensor, and is set by the user as numerical information corresponding to a predetermined item in the present embodiment. To.

In the present embodiment, the template rule is configured to be completed as a temperature change rate dependent rule as an example. According to the temperature change rate dependence rule, when the temperature change rate is high, the temperature change rate at predetermined time is "thermocouple life" so that it is judged that the thermocouple sensor SE is under a high load and deterioration is progressing. It is set as one of the "elements". As an example of the temperature change rate, the temperature change (rising and falling) every minute as shown in FIG. 2 can be mentioned. What is set here is an allowable upper limit of the rate of temperature change, and when this upper limit is exceeded, it is determined that the deterioration of the thermocouple sensor SE has progressed based on the temperature change rate dependence rule.

Further, in the present embodiment, the upper limit of the number of times it is determined that the deterioration has progressed is set as another element in the "thermocouple life element". As a specific example, the template rule shown in FIG. 4A has an upper limit tx of the allowable temperature change rate as a thermocouple life element, an upper limit number of times exceeding the upper limit of the allowable temperature change rate is N, and an upper limit of the allowable temperature change rate. It is expressed by the formula F (tx)> N using the function F (tx) that calculates the number of times the tx is exceeded.

<Embodiment 1 Rule Completion Section>

The “rule completion unit” 0106 executes a process of completing the rule for controlling the output of the thermocouple exchange timing by setting the thermocouple life element in the template rule.

<Embodiment 1 Rule completion part: Thermocouple life element input screen>

Further, the rule completion unit 0106 displays a thermocouple life element input screen (see FIG. 4B) for inputting a thermocouple life element used for output control of the thermocouple exchange timing. The thermocouple life element input screen is stored in the non-volatile memory 0703 (see FIG. 7). A completion rule is created by inputting a predetermined item via the input device I (see FIG. 7) on the input screen as shown in FIG. 4B. It is possible to change the setting again not only at the time of introducing the system of the present embodiment but also after the setting at the time of introduction.

A specific example of the thermocouple life element input screen will be described based on the example of FIG. 4B. On the thermocouple life element input screen, the thermocouple channel display field 04B01, temperature change rate display field 04B02, predetermined excess number display field 04B03, arrow button 04B04, snapshot button 04B05, time display field 04B06, operation button 04B07, copy source A selection button 04B08, a copy destination selection button 04B09, a copy execution button 04B10, and a back button 04B11 are provided.

The thermocouple channel display field 04B01 shows the channel of the thermocouple sensor SE that is the input target (target of the completion rule) of the thermocouple life element in the screen. The thermocouple lifetime element is set for the channel displayed in this display area.

The temperature change rate display column 04B02 is a display area showing a set value of the upper limit of the allowable temperature change rate for the channel displayed in the thermocouple channel display column 04B01. The predetermined excess number display column 04B03 is a display area showing a set value for the upper limit of the number of times that the upper limit of the allowable temperature change rate for the channel displayed in the thermocouple channel display column 04B01 is exceeded. That is, the temperature change rate display column 04B02 and the predetermined excess number display column 04B03 are display areas for the set thermocouple life element.

The arrow button 04B04 is a software key for changing the channel and the value of each upper limit value (thermocouple life element) in the thermocouple channel display column 04B01, the temperature change rate display column 04B02, and the predetermined excess number display column 04B03. .. When the arrow button 04B04 is selected (or touched by the operator) via the input device I or the like, a drop-down list (not shown) is displayed, and candidate setting values are displayed. When any of the candidates is selected, the setting value and channel corresponding to the selected candidate are displayed in the corresponding display column. Further selected candidates are set as setting values or channels. However, the thermocouple channel display field 04B01, the temperature change rate display field 04B02, and the predetermined excess number display field 04B03 may be configured so that numerical values can be directly input.

The snapshot button 04B05 is a software key for capturing (hard copying) the thermocouple life element input screen displayed on the display means such as the display D as it is and generating image data. When this is selected, the display content of the thermocouple life element input screen at that time is stored as image data in a storage means (not shown).

The time display field 04B06 is a display area for displaying the current time. The operation button 04B07 is a software key for starting an operation (for example, starting a setting change) of the thermocouple life element input screen. Until the operation button 04B07 is pressed, the thermocouple life element cannot be input or the channel to be set cannot be changed.

Thermocouple life element The thermocouple life element set on the input screen can be diverted to the setting of other channels. The copy source selection button 04B08, the copy destination selection button 04B09, and the copy execution button 04B10 are software keys for performing the diversion operation. The copy source selection button 04B08 indicates a channel to which the thermocouple life element has been set and which is the diversion source. The copy destination selection button 04B09 indicates a channel to which the setting is changed or newly set. When the copy execution button 04B10 is pressed, the set value of each thermocouple life element of the channel displayed on the copy source selection button 04B08 becomes the set value of each thermocouple life element of the channel displayed on the copy destination selection button 04B09. Will be copied to.

The back button 04B11 is a software key for switching the display to the screen (not shown) displayed immediately before the thermocouple life element input screen.

Explaining the rule completed by the thermocouple life element input screen as described above in the example of FIG. 5, the upper limit tx of the allowable temperature change rate set in "CH1" is "40 ° C./min". When the temperature change every minute exceeds 40 ° C, the function F (40 ° C / min) in the thermocouple exchange timing information output unit 0108 determines that the thermocouple sensor SE has deteriorated and increments the value by 1. .. In the rule, N = 10 (times) is also set as the upper limit N of this number of times, and when this rule satisfies the relationship of the function F (40 ° C./min)> 10, the thermocouple exchange timing information output unit 0108 is set. The output of information indicating that it is the thermocouple exchange timing is executed.

<Embodiment 1 Rule holding unit>

The "rule holding unit" 0107 readablely stores the temperature change rate dependent rule, which is the rule completed by the rule completion unit 0106.

<Embodiment 1 Thermocouple replacement timing information output unit>

The “thermocouple exchange timing information output unit” 0108 obtains the degree of temperature change based on the temperature information of the thermocouple sensor SE and the time measurement information when the thermocouple sensor SE is operating. Based on the obtained result, when the temperature change rate dependence rule generates the thermocouple sensor replacement timing information, the thermocouple replacement timing information is output.

For example, the thermocouple exchange timing information output unit 0108 obtains the temperature change rate for each channel of the thermocouple sensor SE as follows. Here, it is assumed that the thermocouple sensor is provided with a plurality of CH1 to CHn. The thermocouple exchange timing information output unit 0108 acquires the measurement target device temperature information for each of CH1 to CHn for each unit time based on the timekeeping information.

In this case, the thermocouple exchange timing information output unit 0108 sets the difference from the previous measurement target device temperature information in 1 minute units. Find it and use the difference as the temperature change rate (per minute).

Further, the function F (40 ° C./min) provided in the thermocouple exchange timing information output unit 0108 is incremented by 1 when the upper limit of the allowable temperature change rate for each channel in the temperature change rate dependence rule is reached. .. As a premise of the processing of this function, each upper limit value (40 ° C./min) is compared with the calculated temperature change rate for each channel to determine whether the upper limit value is exceeded, and if it is exceeded, the conventional value F is used. The value obtained by adding 1 to is used as the new value of F. It is determined each time the value of F becomes the condition F> 10 of the rule or increments, and when this condition is satisfied, the thermocouple exchange timing information is generated, and the thermocouple exchange timing information output unit 0108 is the thermocouple. Outputs exchange timing information.

An example of the thermocouple exchange timing information in the thermocouple exchange timing information output unit 0108 will be described with reference to FIG. FIG. 6 shows an output state of thermocouple exchange timing information provided on the main body of the apparatus or displayed on a display connected to the main body of the apparatus. In the example of FIG. 6, the thermocouple exchange timing information output unit 0108 reads out such an output screen format from the non-volatile memory 0703 (see FIG. 7) if there is a channel that exceeds the upper limit of the number of times. Further, the thermocouple exchange timing information output unit 0108 displays, for example, the current upper limit of the temperature change rate per minute of each channel and the corresponding temperature change rate of the channel, and the current upper limit of the number of times of excess and the number of times of excess. Assign to format and list. Further, the thermocouple exchange timing information output unit 0108 highlights the channel exceeding the upper limit of the number of determinations so that it can be distinguished from the column of other channels (see reference numeral 0601 in FIG. 6).

As the highlighting, any display method such as a color change identifiable with respect to another screen area, a blinking display, a lighting display, or a highlighting with diagonal lines as shown in FIG. 6 can be adopted. Further, as the output of the thermocouple replacement timing information, the lighting of the warning lamp separately provided or connected to the main body of the apparatus may be used.

<Embodiment 1 Operation Description>

Hereinafter, the operation related to the setting of the completion rule will be described with reference to the flowchart of FIG.

As shown in FIG. 8, first, in order for the user to use the thermocouple sensor device of the present embodiment, the rule completion unit 0106 executes the template rule acquisition step. In this step, the rule completion unit 0106 reads and displays the template rule from the template rule holding unit 0105, and prompts the user to set the completion rule related to the output condition of the thermocouple exchange timing information (step S0801).

When the template rule display screen on which the thermocouple life element can be input is displayed in the predetermined screen area on the display D or the like, the user then determines the thermocouple sensor SE via the input device I (arbitrary input device). The thermocouple lifetime element for each channel is input (Fig. 4B, etc.). In the present embodiment, the upper limit value of the temperature change per unit time and the upper limit value of the number of times the temperature change is exceeded are input. That is, first, the channel of the thermocouple sensor SE is selected (step S0802). Next, the rule holding unit 0107 sets the numerical value input in the predetermined input field as a temperature change upper limit value (step S0803) and an excess number upper limit value (for example, N = 10 (times); step S0804) for each channel. Identify and accept.

Further, the rule holding unit 0107 waits until a signal indicating input completion is input from the input device I or the like (step S0805).

Further, when the signal is input (0805; Yes), the rule holding unit 0107 stores each input value input in steps S0803 and S0804 as a rule (step S0806).

Hereinafter, the operation related to the thermocouple exchange timing information output will be described with reference to the flowchart of FIG.

As shown in FIG. 9, first, the thermocouple exchange timing information output unit 0108 in the thermocouple sensor device has a completion rule (temperature change rate dependence rule) from the rule completion unit 0106 according to the operation of the measurement target device. Is read (step S0901).

Next, the thermocouple exchange timing information output unit 0108 exceeds the upper limit of the temperature change rate up to the present, which is the value of the function (F (40 ° C./min) in FIG. 4A) that forms the rule held in the rule holding unit 0107. The number of times K (K = 0 after replacement of the thermocouple sensor SE at the initial operation) is acquired (step S0902).

Next, the thermocouple exchange timing information output unit 0108 acquires the measurement target device temperature information from the measurement target device temperature information acquisition unit 0101 and the time measurement information from the measurement unit 0103 (step S0903).

Next, the thermocouple exchange timing information output unit 0108 calculates the temperature change rate per unit time (current temperature change rate), and further acquires the upper limit value of the temperature change rate (step S0904).

Next, the thermocouple exchange timing information output unit 0108 compares the current temperature change rate with the upper limit value, and determines whether or not the upper limit value has been exceeded (step S0905). If it does not exceed (S0905; No), the above steps S0902 to S0905 are repeated.

When the thermocouple exchange timing information output unit 0108 determines that the temperature change exceeds the upper limit value (S0905; Yes), the thermocouple exchange timing information output unit 0108 then exceeds the upper limit value of the temperature change per unit time acquired in S0902. The number of times (cumulative number of times) is incremented by 1 (step S0906).

Next, the thermocouple exchange timing information output unit 0108 refers to the completion rule and reads out the upper limit value N of the cumulative number of times that exceeds the upper limit value of the temperature change rate. Further, the thermocouple exchange timing information output unit 0108 determines whether the cumulative number K of the result added in S0906 exceeds the upper limit value N (step S0907). If it does not exceed (S0907; No), the above steps S0903 to S0907 are repeated.

When the thermocouple exchange timing information output unit 0108 determines that the cumulative number of times exceeds the upper limit value (S0907; Yes), the thermocouple exchange timing information output unit 0108 executes output of the thermocouple sensor SE exchange timing information (step S0908).

After the output of the thermocouple sensor SE replacement timing information is executed, the thermocouple replacement timing information output unit 0108 determines whether or not the user has received a signal indicating that the thermocouple sensor SE has been replaced (S0909). For example, after outputting the replacement timing information of the thermocouple sensor SE (not shown), the replacement is detected. Alternatively, a message confirming whether the exchange has been performed is output to the user, and the judgment is made based on the input of the corresponding user. If it is determined that a signal indicating that the exchange has been performed has been received (S0909; Yes), the process returns to step S0901. If it is determined that the replacement has not been performed, (S0909; No) the above steps S0903 to S0908 are repeated.

Each of the above steps is executed for each channel of the thermocouple sensor connected to the thermocouple sensor device.

As described above, according to the first embodiment, the thermocouple life element is different depending on the temperature and atmosphere in the measurement target device and the measurement target object (mold, etc.), which are different for each measurement space of the measurement target device such as a furnace. Can be set. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor according to the progress of deterioration.
<Embodiment 2>
<Outline of Embodiment 2>

In the second embodiment, based on the first embodiment, the completion rule is set from another viewpoint, and the exchange timing information of the thermocouple sensor is output from that viewpoint.
<Embodiment 2 Configuration>

As shown in FIG. 10, the thermocouple sensor device according to the second embodiment also includes the thermocouple sensor SE, the measurement target device temperature information acquisition unit 1001, the measuring unit 1003, the measurement target device operation status information display unit 1004, and a template rule. It has a holding unit 1005, a rule completion unit 1006, a rule holding unit 1007, and a thermoelectric pair exchange timing information output unit 1008. In particular, the rule holding unit has a predetermined excess number-dependent rule holding means. In the following, the description of the configuration similar to that of the first embodiment will be omitted, and the predetermined excess number dependence rule holding means, which is a characteristic configuration of the second embodiment, will be mainly described.
<Explanation of Embodiment 2 Configuration>

The "rule completion unit" 1006 executes a process of completing the rule for outputting the thermocouple exchange timing by setting the thermocouple life element in the template rule. In this embodiment, this rule is a predetermined excess number-dependent rule.

The "rule holding unit" 1007 has a predetermined excess number-dependent rule holding means. As a completed rule, the predetermined excess number-dependent rule holding means exceeds the temperature specified by the acquired measurement target device temperature information for the thermocouple life element at the predetermined measurement target device temperature and the predetermined measurement target device temperature. It holds a predetermined excess number-dependent rule, which is a rule for outputting thermocouple exchange timing information by the number of times. The rule holding unit 1007 readablely stores the predetermined excess number dependence rule completed by the rule completion unit 1006 in the predetermined excess number dependence rule holding means.

<Embodiment 2 Rule depending on the predetermined number of excesses>

In the predetermined excess number dependence rule, the predetermined measurement target device temperature is set as one of the “thermocouple lifetime elements” (see FIG. 11A). The predetermined measurement target device temperature is the ambient temperature in which the thermocouple sensor SE is arranged in the measurement target device, and is set as a high temperature at which the thermocouple sensor deteriorates. The predetermined measurement target device temperature is, for example, the durable temperature for each type of thermocouple sensor. The predetermined measurement target device temperature is measured based on the voltage signal (measurement target device temperature information) from the thermocouple sensor SE.

Further, in the predetermined excess number dependence rule, the upper limit of the cumulative number of times the temperature of the predetermined measurement target device is exceeded is set as another “thermocouple life element” (see FIG. 11A). That is, the permissible range of the number of times that the temperature of the predetermined measurement target device is exceeded is set in the measurement target device, and when the number of times is exceeded, the timing of replacement is assumed that the measurement accuracy by the thermocouple sensor SE cannot be ensured. Can be determined to be.

<Specific example of embodiment 2 thermocouple replacement timing information output>

As a specific example, in the template rule shown in FIG. 11A, the upper limit of the temperature of the predetermined measurement target device is set to tx as the thermocouple life element, and the upper limit of the cumulative number of times exceeding the upper limit of the allowable measurement target device temperature is set to N. It is expressed by the formula F (tx)> N using the function F (tx) that calculates the number of times the temperature of the device to be measured exceeds the upper limit tx.

Explaining in the example of FIG. 12, the upper limit tx of the permissible temperature set in “CH1” is “1100 ° C.”. In CH1 of the thermocouple sensor, when the allowable temperature exceeds 1100 ° C., the function F in the thermocouple exchange timing information output unit 1008 determines that the deterioration of the thermocouple sensor SE has progressed, and the value is incremented by 1. In the predetermined excess number dependence rule, N = 5 (times) is also set as the upper limit N of this number, and when this rule satisfies the relationship of the function F (1100 ° C.)> 5, the thermocouple exchange timing information output unit 1008 Executes the output of information indicating that it is the thermocouple exchange timing.

<Embodiment 2 Thermocouple Life Element Input Screen>

In the second embodiment as in the first embodiment, each setting value and channel can be input from the thermocouple life element input screen, and various displays related to the setting are displayed (see FIG. 11B). That is, even on the thermocouple life element input screen of the second embodiment, the thermocouple channel display column 11B01, the reference temperature display column 11B02, the predetermined excess number display column 11B03, the arrow button 11B04, the snapshot button 11B05, the time display column 11B06, and the operation A button 11B07, a copy source selection button 11B08, a copy destination selection button 11B09, a copy execution button 11B10, and a back button 11B11 are provided. Since these explanations are the same as those in the first embodiment, they will be omitted.

<Output of exchange timing information>

The “thermocouple exchange timing information output unit” 1008 refers to the predetermined excess number dependence rule based on the temperature information of the thermocouple sensor SE acquired from the thermocouple sensor SE when the thermocouple sensor SE is operating, and when a predetermined condition is satisfied, the thermocouple is satisfied. Output exchange timing information.

For example, when a plurality of thermocouple sensors CH1 to CHn are provided, the thermocouple exchange timing information output unit 1008 acquires the temperature information of the device to be measured for each of CH1 to CHn. As an example, the thermocouple exchange timing information output unit 1008 shall acquire the temperature information of the device to be measured, for example, in 1-minute units.

Further, the thermocouple exchange timing information output unit 1008 outputs thermocouple exchange timing information according to the upper limit of the temperature of the device to be measured for each channel in the predetermined excess number dependence rule (see FIG. 12). Further, the thermocouple exchange timing information output unit 1008 compares each of the upper limit values with the temperature of the device to be measured for each acquired channel, and determines whether or not the upper limit value is exceeded. When the predetermined excess number is incremented by 1, the thermocouple exchange timing information output unit 1008 increases the upper limit excess determination number stored in any storage unit such as the rule holding unit 1007 according to the determination result by the predetermined excess number dependence rule. Add to.

Further, the thermocouple exchange timing information output unit 1008 outputs the thermocouple exchange timing information when it is determined by the predetermined excess number dependence rule that the predetermined excess number (determination number) upper limit value has been exceeded.

For example, after outputting the replacement timing information of the thermocouple sensor SE (not shown), the replacement is detected. Alternatively, a message confirming whether the exchange has been performed is output to the user, and the judgment is made based on the input of the corresponding user. If it is determined that the signal indicating that the exchange has been performed has been received (S1609; Yes), the process returns to step S1601. When it is determined that the replacement has not been performed (S1609; No), the above steps S1603 to S1608 are repeated.

Each of the above steps is executed for each channel of the thermocouple sensor connected to the thermocouple sensor device.

When the determination temperature exceeds 1100 ° C., the product of 1 and the "weighting value 4" is added. When the determination temperature exceeds 1200 ° C., the product of 1 and the "weighting value 5" is added.

<Specific example of embodiment 3 rule depending on the number of times the predetermined weighting is exceeded>

In the rule of FIG. 17, N = 100 (time) is also set as the upper limit N of the judgment count correction value corrected by the weighting value, and the function f = 1 * C800 + 2 * C900 + 3 * C1000 + 4 * C1100 +. When this rule satisfies the relationship of 5 * C1200> 100, the thermocouple exchange timing information output unit 1008 outputs information indicating that the thermocouple exchange timing is set.

The "rule completion unit" 1806 executes a process of completing the rule for controlling the output of the thermocouple exchange timing by setting the thermocouple life element in the template rule. In this embodiment, this rule is a time-dependent rule.

The "rule holding unit" 1807 has a predetermined excess time-dependent rule holding means. As a completed rule, the predetermined excess time dependence rule holding means exceeds the temperature specified by the thermocouple life element in the predetermined measurement target device temperature and the measurement target device temperature information obtained from the predetermined measurement target device temperature. It holds a predetermined excess time dependency rule, which is a rule for outputting thermocouple exchange timing information according to time. The rule holding unit 1807 readablely stores the predetermined excess time dependence rule completed by the rule completion unit 1806 by the predetermined excess time dependence rule holding means.

<Embodiment 4 Predetermined Excess Time Dependence Rule>

In the predetermined excess time dependence rule, the predetermined measurement target device temperature is set as one of the “thermocouple lifetime elements” (see FIG. 19A). The predetermined temperature of the device to be measured is the same as that of the above embodiment. Further, in the predetermined excess time dependence rule, the time exceeding the predetermined measurement target device temperature is added, and the upper limit of the cumulative time is set as another “thermocouple life factor” (see FIG. 19A). That is, since the allowable range of the cumulative time exceeding the predetermined measurement target device temperature is set in the measurement target device, the measurement accuracy by the thermocouple sensor SE cannot be ensured when the cumulative time is exceeded. It can be determined that it is time to do so.

<Specific example of embodiment 4 thermocouple life element>

Explaining in the example of FIG. 20, the upper limit tx of the predetermined measurement target apparatus temperature set in “CH1” is “1100 ° C.”. The upper limit of the excess cumulative time is "300 hours". When the temperature of the device to be measured exceeds 1100 ° C., the thermocouple exchange timing information output unit 1808 determines that the thermocouple sensor SE has deteriorated. Here, the thermocouple exchange timing information output unit 1808 has another element, " "Elapsed time" is timed and added to the cumulative time so far. In the rule, the upper limit of this time is also set, and the output of the thermocouple exchange timing is controlled by it.

As a specific example, the template rule shown in FIG. 19A has a cumulative time, which is the total time obtained by adding the time exceeding the upper limit of the allowable measurement target device temperature to the upper limit tx of the predetermined measurement target device temperature as the thermoelectric pair life element. The upper limit of is N, and it is expressed by the formula F (tx)> N using the function F (tx) for calculating the cumulative time exceeding the upper limit tx of the allowable measurement target device temperature.

<Output of exchange timing information>

The "thermocouple exchange timing information output unit" 1808 refers to the predetermined excess time dependence rule based on the temperature information of the thermocouple sensor SE acquired from the thermocouple sensor SE when the thermocouple sensor is operating, and when the predetermined condition is satisfied, the thermocouple is satisfied. Output the replacement timing.

For example, when a plurality of thermocouple sensors CH1 to CHn are provided, the thermocouple exchange timing information output unit 1808 acquires the temperature information of the device to be measured for each of CH1 to CHn. As an example, the thermocouple exchange timing information output unit 1808 shall acquire the temperature information of the device to be measured in 1-minute units.

<Specific example of embodiment 4 thermocouple replacement timing information output>

Explaining in the example of FIG. 20, the upper limit tx of the permissible temperature set in “CH1” is “1100 ° C.”. In CH1 of the thermocouple sensor, when the allowable temperature exceeds 1100 ° C., the function F in the thermocouple exchange timing information output unit 1008 determines that the deterioration of the thermocouple sensor SE has progressed.

The interval at which the temperature information of the device to be measured is acquired is every minute in the above example. Therefore, based on the temperature information of the device to be measured from the “CH1” of the thermocouple sensor SE, it is one minute later that the temperature information is acquired after the first determination that the upper limit Tx has been exceeded. Therefore, if it is determined that the upper limit Tx has been exceeded for the first time and then the upper limit Tx has been exceeded in the next acquisition one minute later, one minute is added to the cumulative time. That is, the cumulative time is added by 1 minute according to the predetermined excess time dependence rule according to the interval of acquiring the temperature information of the device to be measured. This addition is continued until the temperature information of the device to be measured acquired at a predetermined interval becomes equal to or less than the upper limit Tx. The unit of time added to the cumulative time at this predetermined interval (1 minute interval in this example) is defined as the elapsed time T1. The added cumulative time is stored in an arbitrary storage unit such as the rule holding unit 1807.

Further, in the predetermined excess time dependence rule, for example, N = 300 (hours) is also set as the upper limit N of the cumulative time, and the thermocouple exchange timing information output when this rule satisfies the relationship of the function F (1100 ° C.)> 300. Unit 1808 outputs information indicating that it is a thermocouple exchange timing.

<Embodiment 4 Thermocouple Life Element Input Screen>

Since these explanations are the same as those in the first embodiment, they will be omitted.

FIG. 21 shows an output state of thermocouple exchange timing information provided on the main body of the apparatus or displayed on a display connected to the main body of the apparatus. In the example of FIG. 21, the thermocouple exchange timing information output unit 1808 reads out such an output screen format from the non-volatile memory 2203 (see FIG. 22) if there is a channel that exceeds the upper limit of time. Further, the thermocouple exchange timing information output unit 1808 assigns, for example, the cumulative time of the current upper limit temperature exceeding time of each channel and the upper limit value of the cumulative time set in that channel to this screen format and displays them in a list. Further, the thermocouple exchange timing information output unit 1808 highlights the channels that exceed the upper limit of the cumulative time so that they can be distinguished from the columns of other channels (see FIG. 21: reference numeral 2101).

The description of the highlighting mode is the same as that of the first embodiment.

In addition, the non-volatile memory 2203 also stores the temperature information of the device to be measured, the time measurement information, the template rule, the completion rule (“predetermined excess time dependence rule” in this embodiment), and the thermocouple exchange timing information. Others are the same as those in the first embodiment.

<Embodiment 4 Operation Description>

Hereinafter, the operation related to the setting of the completion rule will be described with reference to the flowchart of FIG.

As shown in FIG. 23, first, in order for the user to use the thermocouple sensor device of the present embodiment, the rule completion unit 1806 executes the template rule acquisition step. In this step, the rule completion unit 1806 reads and displays the template rule from the template rule holding unit 1805, and prompts the user to set the completion rule related to the output condition of the thermocouple exchange timing information (step S2301).

When the template rule display screen on which the thermocouple life element can be input is displayed on the display D or the like, the user then uses the input device I to display the thermocouple life for each channel of the thermocouple sensor SE. The element is entered. In the present embodiment, the upper limit value Tx of the temperature of the device to be measured and the upper limit value N of the cumulative overtemperature time are input. That is, first, the channel of the thermocouple sensor SE is selected (step S2302), and then the rule holding unit 1807 sets the numerical value input in the predetermined input field to the measurement target device temperature upper limit value Tx (step S2303) for each channel. And the upper limit of the cumulative time for exceeding the allowable temperature (for example, N = 300 (hours), S2304).

Further, the rule holding unit 1807 waits until a signal indicating input completion is input from the input device I or the like (step S2305).

Further, when the signal is input (S2305; Yes), the rule holding unit 1807 stores each input value input in steps S2303 and S2304 as a rule (step S2306). In some cases, the signal is not input and the channel to be set is selected by returning to step S2302 (S2305; No).

Hereinafter, the operation related to the thermocouple exchange timing information output will be described with reference to the flowchart of FIG. 24.

As shown in FIG. 24, first, the thermocouple exchange timing information output unit 1808 in the thermocouple sensor device has a completion rule (predetermined excess time dependence rule) from the rule completion unit 1806 according to the operation of the measurement target device. Is read (step S2401).

Next, the thermocouple exchange timing information output unit 1808 is the upper limit temperature excess cumulative time K (F (1100 ° C.) in FIG. 19A), which is the value of the function (F (1100 ° C.) in FIG. 19A) that forms the rule held in the rule holding unit 1807. K = 0) is acquired during the initial operation and after the replacement of the thermocouple sensor SE (step S2402).

Next, the thermocouple exchange timing information output unit 1808 acquires the measurement target device temperature information from the measurement target device temperature information acquisition unit 1801 and the time measurement information from the timing unit 1803 (step S2403).

Next, the thermocouple exchange timing information output unit 1808 acquires the upper limit value Tx of the temperature of the device to be measured (step S2404).

Next, the thermocouple exchange timing information output unit 1808 compares the current measurement target device temperature based on the measurement target device temperature information with the upper limit value Tx, and determines whether or not the upper limit value has been exceeded (step S2405A). If it does not exceed (S2405A; No), the above steps S2403 to S2405A are repeated.

When the thermocouple exchange timing information output unit 1808 determines that the temperature of the device to be measured exceeds the upper limit Tx and continues at a predetermined interval (S2405A; Yes), the temperature excess continues for one interval (acquisition of temperature information of the device to be measured). It is determined whether the interval (for example, 1 minute) or more is continued (step S2405B). When the thermocouple exchange timing information output unit 1808 makes the first determination of the temperature excess in S2405A and then makes the second and subsequent determinations, it may be configured as "continuing" in this determination. Alternatively, this judgment may be timed based on the timekeeping information from the time when the temperature exceeds the time limit.

When it is determined that the temperature of the device to be measured exceeds the upper limit Tx and continues at a predetermined interval (S2405A; Yes), the time interval for acquiring the temperature information of the device to be measured (for example, 1 minute) is set as the elapsed time T1 (step S2406). It is added to the cumulative time K acquired in S2402 (step S2407).

Next, the thermocouple exchange timing information output unit 1808 refers to the completion rule and reads out the upper limit value N of the cumulative time exceeding the upper limit value of the temperature of the device to be measured. Further, the thermocouple exchange timing information output unit 1808 determines whether the cumulative time exceeds the upper limit value N (K> N) as a result of the addition in S2407 (step S2408). If it does not exceed (S2408; No), the above steps S2403 to S2408 are repeated.

When it is determined that the cumulative time exceeds the upper limit value (S2408; Yes), the thermocouple exchange timing information output unit 1808 outputs the exchange timing information of the thermocouple sensor SE (S2409).

After the output of the thermocouple sensor SE replacement timing information is executed, the thermocouple replacement timing information output unit 1808 determines whether or not the user has received a signal indicating that the thermocouple sensor SE has been replaced (S2410). For example, after outputting the replacement timing information of the thermocouple sensor SE (not shown), the replacement is detected. Alternatively, a message confirming whether the exchange has been performed is output to the user, and the judgment is made based on the input of the corresponding user. If it is determined that the signal indicating that the exchange has been performed has been received (S2410; Yes), the process returns to step S2401. If it is determined that the replacement has not been performed, (S2410; No) the above steps S2403 to S2409 are repeated.

Each of the above steps is executed for each channel of the thermocouple sensor connected to the thermocouple sensor device.

As described above, according to the fourth embodiment, the thermocouple life element can be set according to the temperature in the measurement target device, which is different for each measurement space of the measurement target device such as a furnace. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor according to the progress of deterioration.
<Embodiment 5>
<Outline of Embodiment 5>

The fifth embodiment performs weighting correction based on the fourth embodiment. That is, it is an embodiment in which the completion rule of the third embodiment is replaced with a predetermined weighting excess time dependence rule from a predetermined weighting excess number dependence rule.
<Embodiment 5 Rule Holding Unit>

The rule holding unit 1807 has a predetermined weighting excess time dependence rule. As a completed rule, the predetermined weighting excess time dependence rule holding means is weighted with a thermocouple life element having a predetermined measurement target device temperature, a weighting value set according to a predetermined measurement target device temperature, and the weighting thereof. It holds a predetermined weighted excess time dependence rule, which is a rule for outputting thermocouple exchange timing information according to the time when the temperature specified by the temperature information of the device to be measured that has acquired the temperature of the device to be measured exceeds.

That is, the thermocouple life element of the fifth embodiment includes a plurality of "determination temperatures" as predetermined measurement target device temperatures, "weighted values" set according to the predetermined measurement target device temperature, and "plurality of weighted values". It is the sum of the values obtained by correcting the cumulative time exceeding the determination temperature with the weighted value. " The thermocouple exchange timing information is output based on this correction value.

The predetermined weighted excess time dependent rule holding means in the rule holding unit 1807 holds the predetermined weighted excess time dependent rule. An example of the predetermined weighted excess time dependence rule, which is the completion rule of the fifth embodiment, will be described with reference to the example shown in FIG. In the fifth embodiment, the upper limit of the allowable temperature of the thermocouple sensor is not uniformly set, but the "determination temperature" that is considered to impose a load on the thermocouple sensor is set stepwise as the first thermocouple life element. Will be done. Further, as the second thermocouple life element, a weighting value corresponding to the stepwise determination temperature is set. The weighted value is the same as that of the third embodiment. Further, as in the third embodiment, the sum of the numerical values corrected by the weighting value is used for the excess determination cumulative time for each determination temperature. The setting is made with this sum as the upper limit. This upper limit is the third thermocouple lifetime element in the fifth embodiment.

<Specific example of embodiment 5 thermocouple life element>

Explaining in the example of FIG. 25, the determined allowable temperature set is "800 ° C", "900 ° C", "1000 ° C", "1100 ° C", and "1200 ° C". The weighting values are "1" for "800 ° C", "2" for "900 ° C", "3" for "1000 ° C", and "4" for "1100 ° C". It is "5" with respect to "1200 ° C".

That is, when the determination temperature exceeds 800 ° C., the function F in the thermocouple exchange timing information output unit 1808 determines that the deterioration of the thermocouple sensor SE has progressed, measures the elapsed time (for example, 400 hours), and further Tn ₁ . Is calculated as a product of "weighted value 1". When the determination temperature exceeds 900 ° C., the elapsed time (for example, 350 hours) is timed, and the product of Tn ₂ and the “weighted value 2” is obtained. When the determination temperature exceeds 1000 ° C., the elapsed time (for example, 300 hours) is timed, and the product of Tn ₃ and the “weighted value 3” is obtained. When the determination temperature exceeds 1100 ° C., the elapsed time (for example, 250 hours) is timed, and the product of the “weighted value 4” as Tn ₄ is obtained. When the determination temperature exceeds 1200 ° C., the elapsed time (for example, 200 hours) is timed, and the product of the “weighted value 5” as Tn ₅ is obtained.

In the rule of FIG. 25, N = 5000 (hours) is also set as the upper limit N of the cumulative time correction value corrected by the weighting value, and the function f = Tn ₁ * C800 + Tn ₂ * C900 + Tn ₃ * C1000 + Tn. ₄ When this rule satisfies the relationship of * C1100 + Tn ₅ * C1200> 5000, the thermocouple exchange timing information output unit 1808 outputs information indicating that the thermocouple exchange timing is set.

Each of the determination temperatures in the fifth embodiment is set by the user, and is set based on, for example, the durable temperature. That is, the lower limit of the determination temperature may be the serviceable temperature of the thermocouple sensor, and the serviceable temperature may be set as the upper limit value or the median value.

As described above, according to the fifth embodiment, the thermocouple life element is set according to the temperature, atmosphere, and the object to be measured (mold, etc.) in the device to be measured, which is different for each measurement space of the device to be measured such as a furnace. Can be set. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor according to the progress of deterioration. Further, in the fifth embodiment, a plurality of determination temperatures for determining the deterioration of the thermocouple sensor and the weighting correction for each determination temperature of the accumulated time exceeding the determination temperature are performed. Therefore, it is possible to present a more detailed replacement timing of the thermocouple sensor.

<Embodiment 6 Operation Description>

Hereinafter, the operation related to the setting of the completion rule will be described with reference to the flowchart of FIG.

As shown in FIG. 31, first, in order for the user to use the thermocouple sensor device of the present embodiment, the rule completion unit 2606 executes the template rule acquisition step. In this step, the rule completion unit 2606 reads and displays the template rule from the template rule holding unit 2605, and prompts the user to set the completion rule related to the output condition of the thermocouple exchange timing information (step S3101).

When the template rule display screen on which the thermocouple life element can be input is displayed on the display D or the like, the user then uses the input device I to display the thermocouple life for each channel of the thermocouple sensor SE. The element is entered. In the present embodiment, the upper limit of the temperature of the device to be measured, the upper limit of the number of times the upper limit of the device to be measured exceeds the temperature, and the upper limit of the time of exceeding the temperature of the device to be measured are input. That is, first, the channel of the thermocouple sensor SE is selected (step S3102), and then the rule holding unit 2607 sets the numerical value input in the predetermined input field to the measurement target device temperature upper limit value Tx (step S3103) for each channel. And the upper limit of the number of times and the upper limit of the cumulative time (N ₁ = 10, N ₂ = 100; step S3104).

Further, the rule holding unit 2607 waits until a signal indicating input completion is input from the input device I or the like (step S3105).

Further, when the signal is input (S3105; Yes), the rule holding unit 2607 stores each input value input in steps S3103 and S3104 as a rule (step S3106). The channel to be set may be selected by returning to step S3102 without inputting the signal (S3105; No).

Hereinafter, the operation related to the thermocouple exchange timing information output will be described with reference to the flowchart of FIG.

As shown in FIG. 32, first, the thermocouple exchange timing information output unit 2608 in the thermocouple sensor device has a completion rule (a rule depending on a predetermined excess number of times) from the rule completion unit 2606 according to the operation of the measurement target device. The predetermined excess time dependency rule) is read (step S3201).

Next, the thermocouple exchange timing information output unit 2608 is the upper limit excess cumulative time K1 up to the present, which is the value of the function (F (1100 ° C.) in FIGS. 11A and 19A) that forms the rule held in the rule holding unit 2607. And the number of times the upper limit temperature is exceeded K2 (step S3202). At the time of initial operation, after the thermocouple sensor SE is replaced, K1 = 0 and K2 = 0.

Next, the thermocouple exchange timing information output unit 2608 acquires the measurement target device temperature information from the measurement target device temperature information acquisition unit 2601 and the time measurement information from the timing unit 2603 (step S3203).

Next, the thermocouple exchange timing information output unit 2608 acquires the upper limit value Tx of the temperature of the device to be measured (step S3204).

Next, the thermocouple exchange timing information output unit 2608 compares the current measurement target device temperature based on the measurement target device temperature information with the upper limit value, and determines whether or not the upper limit value Tx has been exceeded (step S3205A). If it does not exceed (S3205A; No), the above steps S3203 to S3205A are repeated.
When it is determined that the temperature of the device to be measured exceeds the upper limit Tx and continues at a predetermined interval (S2405A; Yes).

When the thermocouple exchange timing information output unit 2608 determines that the temperature of the device to be measured exceeds the upper limit Tx and continues at a predetermined interval (S3205A; Yes), the temperature excess continues for one interval (acquisition of temperature information of the device to be measured). It is determined whether the interval (for example, 1 minute) or more is continued (step S3205B). The thermocouple exchange timing information output unit 2608 is configured to determine "continuing" in this determination when the first determination of the temperature excess in S3205A is made and then the second and subsequent determinations are made. May be good. Alternatively, this judgment may be timed based on the timekeeping information from the time when the temperature exceeds the time limit.

When the thermocouple exchange timing information output unit 2608 determines that the temperature of the device to be measured exceeds the upper limit and continues at a predetermined interval (S3205B; Yes), the time interval for acquiring the temperature information of the device to be measured (for example, 1 minute) is set. As the elapsed time T1 (step S3206), it is added to the cumulative time K1 acquired in _S3202 (step S3207).

Similarly, when it is determined that the temperature of the device to be measured exceeds the upper limit value (S3205A; Yes), the number of times the upper limit value of the device temperature to be measured is exceeded is added and incremented by 1 to K ₂ acquired in S3202 (step S3208). The timekeeping of the excess time and the addition of the number of excess times may be performed first or simultaneously.

Next, the thermocouple exchange timing information output unit 2608 refers to the completion rule and reads out the upper limit values N ₁ and N ₂ of the cumulative number of times and times when the upper limit value of the temperature of the device to be measured is exceeded. Further, the thermocouple exchange timing information output unit 2608 determines whether the cumulative time K1 of _S3207 exceeds the upper limit value N1 or the cumulative number of times K2 of _S3208 exceeds _{N2 (} step S3209). If _both the cumulative time K1 and the cumulative number of times K2 are not exceeded ( _S3209 ; No), the above steps S3203 to S3209 are repeated.

When the thermocouple exchange timing information output unit 2608 determines that the cumulative time K1 or the cumulative number of times K2 exceeds the corresponding upper limit value _{( S3209} ; Yes), the thermocouple sensor SE exchange timing information is output (S). S3210).

After the output of the thermocouple sensor SE replacement timing information is executed, the thermocouple exchange timing information output unit 2608 determines whether or not the user has received a signal indicating that the thermocouple sensor SE has been replaced (S3211). For example, after outputting the replacement timing information of the thermocouple sensor SE (not shown), the replacement is detected. Alternatively, a message confirming whether the exchange has been performed is output to the user, and the judgment is made based on the input of the corresponding user. If it is determined that the signal indicating that the exchange has been performed has been received (S3211; Yes), the process returns to step S3201.

As shown in FIG. 33, the thermocouple sensor device according to the seventh embodiment also includes the thermocouple sensor SE, the measurement target device temperature information acquisition unit 3301, the measuring unit 3303, the measurement target device operation status information display unit 3304, and a template rule. It has a holding unit 3305, a rule completion unit 3306, a rule holding unit 3307, a thermoelectric pair exchange timing information output unit 3308, a measurement target device specific information holding unit 3302, and a setting support information output unit 3309. Hereinafter, the description of the configuration similar to that of the first to sixth embodiments will be omitted, and the setting support information holding means of the thermocouple life element, which is a characteristic configuration of the seventh embodiment, will be mainly described.

<Embodiment 7 Configuration: Measurement target device specific information holding unit>

The measurement target device specific information holding unit 3302 holds the measurement target device specific information. In the example of the seventh embodiment, the rule holding unit 3307 stores the type of the thermocouple sensor for each channel of the thermocouple sensor SE used in the measurement target device. The stored attribute information of the thermocouple sensor is an example of the information unique to the device to be measured. According to the example in FIG. 34, the manufacturer, type, wire diameter, and protective tube material of the thermocouple sensor used are stored.

The degree of deterioration (durability) of the thermocouple sensor differs depending on the manufacturer, type, wire diameter, and protective tube material of the thermocouple sensor. Therefore, when setting the thermocouple life element in the above embodiment, the thermocouple life element is set. By providing the user with information on supporting the setting of the thermocouple life element according to the type of the thermocouple, it is possible to set the thermocouple life element more accurately.

<Embodiment 7 Setting support information output unit>

The setting support information output unit 3309 of the seventh embodiment outputs the setting support information of the thermocouple life element corresponding to the measurement target device specific information. As an example, the reference of the thermocouple life element in each embodiment in the thermocouple sensor SE based on the index of the susceptibility to deterioration of each thermocouple sensor predicted from the attribute information of the thermocouple sensor as shown in FIG. 34. A value (recommended value) may be displayed on the display D (not shown) as setting support information.

<Specific example of embodiment 7 setting support information>

The setting support information output unit 3309 executes this display. The thermocouple life element in each embodiment is corrected by the upper limit of the allowable measurement target device temperature, the predetermined number of excesses (Embodiment 1), the upper limit of the allowable temperature excess (Embodiments 2 and 6), and the weighting value. The upper limit of the number of times the allowable temperature is exceeded (Embodiment 3), the upper limit of the allowable temperature excess time (Embodiments 4 and 6), the upper limit of the allowable temperature excess time corrected by the weighting value (Embodiment 5), and the like.

As a modification of the above setting support information, the range (upper limit value and lower limit value) of the reference value (recommended value) of the thermocouple life element is displayed as the setting support information based on the index of the susceptibility to deterioration based on the attribute information. May be displayed in (not shown).

Further, as another example, after the thermocouple life element in each of the above embodiments is set by the user, a proposal for correcting the numerical value of the thermocouple life element after the setting is used as setting support information according to the type of the thermocouple and the like. It may be the configuration to be displayed. Proposals for modifying the numerical values of the thermocouple life element after setting include, for example, the following.

First, the index is set as a coefficient based on the index of susceptibility to deterioration for each thermocouple sensor, which is predicted from the attribute information of the thermocouple sensor. The numerical value of the thermocouple life element set by the user is corrected based on the coefficient, and the corrected value is displayed on the display D as setting support information in the same manner as described above.

After displaying the setting support information on the display D, the setting support information output unit 3309 has a message prompting the user to select whether to apply the setting support information as it is as a thermocouple life element, and a display for making a selection. ("Y / N", etc.) may be displayed. In this case, the rule completion unit 3306 waits until a signal indicating one of the selections is input from the input device I or the like, and when the selection is made, sets the thermocouple lifetime element accordingly.

When the range of the reference value (recommended value) of the thermocouple life element is the setting support information, the setting support information output unit 3309 waits until a signal indicating one of the selections is input from the input device I or the like. When the setting support information output unit 3309 is input to adopt the setting support information, the display can input the range of the reference value (recommended value) of the thermocouple life element and the thermocouple life element within the range. I do. When any numerical value within the range is input via the input device I or the like, the thermocouple lifetime element is set accordingly.

As described above, according to the seventh embodiment, the thermocouple life element is different depending on the temperature and atmosphere in the measurement target device and the measurement target object (mold or the like), which are different for each measurement space of the measurement target device such as a furnace. Can be set. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor according to the progress of deterioration. Further, in the seventh embodiment, it is possible to present the user with the setting support information of the life element of the thermocouple based on the measurement target device specific information such as the attribute information of the thermocouple sensor. It is possible to support the setting of users with little knowledge and experience, and it is possible to prevent setting mistakes by presenting the setting support information to users with abundant experience. Therefore, it is possible to present a more detailed replacement timing of the thermocouple sensor.
<Embodiment 8>
<Outline of Embodiment 8>

In the eighth embodiment, the weighting element of the third embodiment is set based on the measurement target device specific information including the attribute information of the thermocouple sensor SE.

In the predetermined weighting excess number dependence rule of the third embodiment, a "determination temperature" at which a load is applied to the thermocouple sensor is set stepwise as the first thermocouple life element. Further, as the second thermocouple life element, a weighting value corresponding to the stepwise determination temperature is set. In the eighth embodiment, the weighted value of the second thermocouple lifetime element is set by the measurement target device specific information including the attribute information of the thermocouple sensor SE.

For example, as shown in the table on the left side of FIG. 35, the rule holding unit 1007 holds a weighted value for each stepwise determination temperature according to the attribute information of the thermocouple sensor for each channel of the thermocouple sensor SE. There is. This retention is automatically given by the present device when the attribute information of the thermocouple sensor for each channel is given. The attribute information of the thermocouple sensor may be automatically read by the present device from the information stored in the thermocouple sensor itself, or may be manually input by the user or the operator. In addition, K ₁ in the table on the left side is a weighting value corresponding to a determination temperature of 800 ° C. Similarly, K ₂ is a weighting value corresponding to a determination temperature of 900 ° C., K ₃ is a weighting value corresponding to 1000 ° C., K ₄ is a weighting value corresponding to 1100 ° C., and K ₅ is a weighting value corresponding to 1200 ° C.

This embodiment will be described in this example. For example, when the determination temperature of the channel CH1 exceeds 800 ° C., the function F in the thermocouple exchange timing information output unit 0108 determines that the thermocouple sensor SE has deteriorated, and the product of 1 and the "weighting value 4" is Will be added. When the determination temperature exceeds 900 ° C., the product of 1 and the "weighting value 5" is added. When the determination temperature exceeds 1000 ° C., the product of 1 and the "weighting value 6" is added. When the determination temperature exceeds 1100 ° C., the product of 1 and the "weighting value 7" is added. When the determination temperature exceeds 1200 ° C., the product of 1 and the "weighting value 8" is added.

<Specific example of the rule depending on the number of times of excess of the predetermined weighting in the eighth embodiment>

In the rule of FIG. 35, N = 150 (times) is also set as the upper limit N of the judgment count correction value corrected by the weighting value, and the function f = K ₁ * C800 + K ₂ * C900 + K ₃ * C1000 + K ₄ * C1100 +. When this rule satisfies the relationship of K5 * _C1200 > 150, the thermocouple exchange timing information output unit 1008 outputs information indicating that the thermocouple exchange timing is reached.

As described above, according to the eighth embodiment, an appropriate thermocouple life element is set according to the attribute of the thermocouple sensor installed in the measurement target device, which is different for each measurement space of the measurement target device such as a furnace. Weighting is automated so that it can be done. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor by assuming the progress of deterioration depending on the attributes of the different thermocouple sensors even if the atmosphere is the same or the same object to be measured (mold, etc.). .. Further, in the eighth embodiment, a plurality of determination temperatures for determining deterioration of the thermocouple sensor and weighting correction for each determination temperature of the number of times the determination temperature is exceeded are performed by an index (coefficient) based on the attribute information of the thermocouple sensor. It is also possible to do it.
<Embodiment 9>
<Outline of Embodiment 9>

In the ninth embodiment, the weighting element of the fifth embodiment is set based on the measurement target device specific information including the attribute information of the thermocouple sensor SE.

In the predetermined weighting excess time dependence rule of the ninth embodiment, the "determination temperature" is set stepwise as the first thermocouple life element. Further, as the second thermocouple life element, a weighted value corresponding to the stepwise determination temperature is set based on the measurement target device specific information including the attribute information of the thermocouple sensor SE.

For example, as shown in FIG. 36, the rule holding unit 1807 stores a weighted value for the time actually exceeded for each channel of the thermocouple sensor SE and for each stepwise determination temperature according to the attribute information of the thermocouple sensor. are doing.

For example, a "weighting value 1" is set as Tn ₁ for a determination temperature of 800 ° C., a "weighting value 2" is set as Tn ₂ for a determination temperature of 900 ° C., and a "weighting value 2" is set as Tn ₃ for a determination temperature of 1000 ° C. The "value 3" is set as a "weighting value 4" as Tn ₄ for the determination temperature of 1100 ° C., and the "weighting value 5" is set as Tn ₅ for the determination temperature of 1200 ° C., respectively. ..

In the following, a process is executed in which the predetermined weighting excess number dependence rule of the eighth embodiment is replaced with the predetermined weighting excess time dependence rule. For example, when the determination temperature of the channel CH1 exceeds 800 ° C., the function F in the thermocouple exchange timing information output unit 1808 determines that the thermocouple sensor SE has deteriorated, and measures the elapsed time (for example, 400 hours). Further, the product of "weighting value 4" is obtained as Tn ₁ . When the determination temperature exceeds 900 ° C., the elapsed time (for example, 350 hours) is timed, and the product of Tn ₂ and the “weighted value 5” is obtained. When the determination temperature exceeds 1000 ° C., the elapsed time (for example, 300 hours) is timed, and the product of Tn ₃ and the “weighted value 6” is obtained. When the determination temperature exceeds 1100 ° C., the elapsed time (for example, 250 hours) is timed, and the product of the “weighted value 7” as Tn ₄ is obtained. When the determination temperature exceeds 1200 ° C., the elapsed time (for example, 200 hours) is timed, and the product of Tn ₅ and the “weighted value 8” is obtained.

<Specific example of embodiment 9 predetermined weighting excess time dependence rule>

As an example, N = 5000 (time) is also set as the upper limit N of the judgment time correction value corrected by the weighting value, and the function f = Tn ₁ * C800 + Tn ₂ * C900 + Tn ₃ * C1000 + Tn ₄ * C1100 + Tn ₅ * C1200. When this rule satisfies the relationship of> 5000, the thermocouple exchange timing information output unit 1808 outputs information indicating that the thermocouple exchange timing is reached.

The ninth embodiment can be combined with the eighth embodiment.

As described above, according to the ninth embodiment, the thermocouple life element is different depending on the temperature and atmosphere in the measurement target device and the measurement target object (mold or the like), which are different for each measurement space of the measurement target device such as a furnace. Can be set. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor according to the progress of deterioration. Further, in the ninth embodiment, a plurality of determination temperatures for determining deterioration of the thermocouple sensor and weighting correction for each determination temperature of the determination temperature excess time are performed by an index (coefficient) based on the attribute information of the thermocouple sensor. Run. Therefore, it is possible to present a more detailed replacement timing of the thermocouple sensor.

<Explanation of Embodiment 10 Configuration>

<Embodiment 10 Measurement target device operation status information display device>
The measurement target device operation status information display device is used by the administrator and the operator of the measurement target device, and is generally arranged in the vicinity of the measurement target device so that the process can be easily managed. It is placed at a position where the signal from the thermocouple installed in the measurement target device can be acquired accurately.

The "replaceable thermocouple sensor SE", "measurement target device temperature information acquisition unit 3701", "timekeeping unit 3703", and "measurement target device operation status information display unit 3704" are as described above. Since there is, the explanation is omitted.

The “measurement target device operation status information transmission unit” outputs the operation status information of the measurement target device to the thermocouple exchange timing information output server. In principle, the output is performed in real time, but in detail, the information may be configured to be transmitted in batches every few seconds. Furthermore, it is also possible to adopt a configuration that outputs after the fact. In other words, it is configured to transmit information in real time and output it in layers after the fact. It can be used to confirm the status of the processing process again after the fact. Further, the destination is not limited to one server, and may be configured to be transmitted to a plurality of servers. Further, the information may be transmitted to the heat exchange timing information output server described above as a transmission destination, and may also be transmitted to another terminal. For example, it can be configured so that the status information of the device to be measured can be known even if it is transmitted to the mobile terminals of a plurality of managers related to the processing process and is located at a remote location. As the operation status information, it is also possible to communicate with IoT devices in the vicinity of the measurement target device and transmit the information obtained from them. As IoT devices in the vicinity, devices that operate in cooperation with each other, information on mobile terminals carried by managers who manage processes, biometric information of managers themselves, and devices to be measured are installed.

The reception format is as described above, and there may be a plurality of reception formats of a method of receiving in real time and a method of receiving after the fact. Further, since a slight time delay occurs even when the information is received in real time, it is possible to record the timekeeping information of the transmission source and the timekeeping information at the time of reception, or to record the difference value. In particular, when process control and monitoring all over the world are performed in one place via a worldwide network, it is necessary to establish a standard for timekeeping information.

In that case, the completed rule is sent to the server side and used. Further, the rule completion unit can be configured to be completed on the server side in a form of accepting information input from the client side.
The "rule holding unit" holds the corresponding completion rule for each connected measurement target device operation status information display device. Therefore, it is preferable to configure the rule so as to be associated with the identification information of the measurement target device operation status information display device.
The template rule held by the template rule holding unit 3705 may be different for each connected measurement target device operation status information display device, and may be different for each of the connected measurement target device operation status information display devices. Of these, those common to two or more devices may be used.

The "thermoelectric pair exchange timing information output unit" 3708 is a completion rule for the received measurement target device operation status information and the held rule, that is, the measurement target device operation status information display device that has transmitted the measurement target device operation status information. The thermocouple exchange timing information is output based on. The output of the thermocouple exchange timing information may be configured to be displayed in a list in association with the identification information of the measurement target device operation status information display device managed via the network. The operation status information from the measurement target device operation status information display device is transmitted in association with the identification information of each device, and is received by this server.

The output destination of the thermocouple exchange timing information is the measurement target device operation status information display device that has transmitted the measurement target device operation status information among the connected measurement target device operation status information display devices. The measurement target device operation status information display device receives the thermocouple replacement timing information and notifies the user or the administrator that it is the thermocouple replacement timing. The method of this notification is as described above.

As described above, according to the tenth embodiment, the thermocouple life element is different depending on the temperature and atmosphere in the measurement target device and the measurement target object (mold or the like), which are different for each measurement space of the measurement target device such as a furnace. Can be set. As a result, it is possible to present an appropriate replacement timing of the thermocouple sensor according to the progress of deterioration.
