Description
本發明關於一種對控制物件的溫度進行控制的溫度調節計及異常判斷方法。The invention relates to a temperature regulator for controlling the temperature of a control object and an abnormality judgment method.
對各種溫度環境等的溫度進行調節的溫度調節計將使用熱電偶或測溫電阻體等溫度感測器所檢測出的監視物件的溫度進行數值顯示,而且根據所檢測出的溫度及設定溫度而求出對加熱器的控制輸出,控制監視物件的溫度。A thermostat that adjusts the temperature of various temperature environments, etc., displays the temperature of the monitoring object detected by a temperature sensor such as a thermocouple or a resistance temperature sensor, and displays the temperature based on the detected temperature and the set temperature. Obtain the control output to the heater and control the temperature of the monitored object.
此外,加熱器當錯誤操作時會破損,因此對於溫度調節計等控制加熱器的設備,通常可進行下述那樣的警報設定或控制輸出的設定(參照專利文獻1、專利文獻2)。加熱器的利用者使用這些功能來輸出警報,而且限制流經加熱器的電流。In addition, the heater may be damaged if it is operated incorrectly. Therefore, for devices that control the heater, such as a temperature regulator, the following alarm settings or control output settings can usually be performed (see Patent Document 1 and Patent Document 2). The user of the heater uses these functions to output an alarm and limit the current flowing through the heater.

現有技術文獻 專利文獻 專利文獻1:日本專利特開平09-243098號公報 專利文獻2:日本專利特開平01-298385號公報Prior art literature Patent literature Patent Document 1: Japanese Patent Laid-Open No. 09-243098 Patent Document 2: Japanese Patent Laid-Open No. 01-298385
如上文所述那樣,加熱器會因為操作的錯誤而破損。例如,當欲以額定值以上的溫度變化率(例如100℃/s)升溫時,加熱器破損。溫度變化率視加熱器的每個種類而特性不同,而且與溫度變化率相關的規格是由加熱器的製造廠商標示。加熱器特性有時視溫度而變化,溫度變化率視溫度域而不同,但由加熱器的製造廠商標示的與溫度變化率相關的規格大多為可在整個溫度區域中安全使用的代表值。因此,例如即便由加熱器的製造廠商標示的與溫度變化率相關的規格為50℃/s,但實用上若為200℃以下,則即便是80℃/s加熱器也不會破損。As mentioned above, the heater may be damaged due to operating errors. For example, when it is desired to increase the temperature at a temperature change rate higher than the rated value (for example, 100°C/s), the heater is broken. The temperature change rate varies with each type of heater, and the specifications related to the temperature change rate are indicated by the heater manufacturer. Heater characteristics sometimes change depending on the temperature, and the temperature change rate differs depending on the temperature range. However, most of the specifications related to the temperature change rate indicated by the heater manufacturer are representative values that can be used safely in the entire temperature range. Therefore, for example, even if the specification related to the temperature change rate indicated by the heater manufacturer is 50°C/s, in practice, if it is 200°C or less, the heater will not be damaged even if it is 80°C/s.
另外,作為加熱器的特性,即便使溫度變化至規定的溫度變化率以上,但若變化的時間為短時間,則有時也未至劣化。例如,即便由加熱器的製造廠商標示的與溫度變化率相關的規格為50℃/s,但若設為80℃/s的時間為10s以下,則加熱器也不會破損。In addition, as a characteristic of the heater, even if the temperature is changed to a predetermined temperature change rate or higher, if the change time is a short time, the deterioration may not occur. For example, even if the specification related to the temperature change rate indicated by the heater manufacturer is 50°C/s, if the time of 80°C/s is 10s or less, the heater will not be damaged.
通常的溫度變化率的警報是基於由加熱器的製造廠商標示的溫度變化率而設定。當超過所述設定值時,溫度調節計輸出警報,並且減小輸出的MV值(例如設為0%)。但是,這種控制的限制是基於由加熱器的製造廠商標示的溫度變化率而設定,因此視加熱器的溫度、或溫度變化率超過上限的時間不同,有時即便超過限制也不會導致加熱器的破損。如此,當即便超過限制也可不導致破損地使用加熱器時,通過在所述範圍內使用加熱器,從而有能夠使溫度的控制性更好的可能性。The usual temperature change rate alarm is set based on the temperature change rate indicated by the heater manufacturer. When the set value is exceeded, the temperature regulator outputs an alarm and reduces the output MV value (for example, set to 0%). However, the limit of this control is set based on the temperature change rate indicated by the heater manufacturer. Therefore, depending on the temperature of the heater or the time when the temperature change rate exceeds the upper limit, sometimes it will not cause heating even if the limit is exceeded. Damage to the device. In this way, when the heater can be used without causing damage even if the limit is exceeded, by using the heater within the above-mentioned range, there is a possibility that the controllability of the temperature can be improved.
如以上那樣,以前雖然可防止加熱器破損,但存在未充分發揮加熱器的能力等問題。As described above, although heater damage can be prevented in the past, there are problems such as insufficient performance of the heater.
本發明是為了消除以上那樣的問題點而成,其目的在於可在不導致加熱器破損的範圍內充分發揮加熱器的能力。The present invention is made in order to eliminate the above-mentioned problems, and its object is to fully exhibit the capabilities of the heater within a range that does not cause damage to the heater.

以下,對本發明的實施方式的溫度調節計進行說明。Hereinafter, the temperature regulator according to the embodiment of the present invention will be described.
實施方式1
首先,參照圖1對本發明的實施方式1的溫度調節計進行說明。所述溫度調節計控制加熱器101的加熱能力,將控制物件的溫度控制為預先設定的設定溫度。所述溫度調節計包括測定部102、計算部103、第一檢測部104、第二檢測部105、第一測量部106、判斷部107、輸出部108、判定值記憶部120以及控制部121。Embodiment 1
First, referring to Fig. 1, a temperature regulator according to Embodiment 1 of the present invention will be described. The temperature regulator controls the heating capacity of the heater 101, and controls the temperature of the controlled object to a preset temperature. The temperature regulator includes a measurement unit 102, a calculation unit 103, a
測定部102測定加熱器101的溫度。控制部121根據測定部102所測定的測定溫度與所設定的設定溫度的關係,生成用於加熱器101的運行控制的控制值並輸出,所述加熱器101將控制物件加熱。The measuring unit 102 measures the temperature of the heater 101. The control unit 121 generates and outputs a control value for operation control of the heater 101 based on the relationship between the measurement temperature measured by the measurement unit 102 and the set set temperature. The heater 101 heats the control object.
計算部103求出測定部102所測定的加熱器101的每單位時間的溫度上升變化作為升溫速度。第一檢測部104檢測測定部102所測定的測定溫度超過保存在判定值記憶部120的預先設定的第一值。例如,可設定250℃作為第一值。第二檢測部105檢測計算部103所求出的升溫速度超過預先設定的第二值。例如,可設定50℃/秒作為第二值。The calculation unit 103 obtains the temperature rise change per unit time of the heater 101 measured by the measurement unit 102 as the temperature increase rate. The
第一測量部106測量下述狀態持續的時間,所述狀態為第一檢測部104檢測到測定溫度超過第一值,且第二檢測部105檢測到升溫速度超過第二值的狀態。當第一測量部106測量的時間超過保存在判定值記憶部120的預先設定的第一計時器設定值時(第一時間),判斷部107判斷為異常。第一計時器設定值例如可設為2秒。當判斷部107判斷為異常時,輸出部108輸出警報。例如,在未圖示的顯示部顯示產生了異常。另外,使用喇叭、揚聲器等通過聲音等發出通知作為警報。The
例如,以往,當由加熱器的製造廠商標示的與溫度變化率相關的規格為50℃/s時,將50℃/s設定為根據所測定的溫度而求出的升溫速度的判定值。因此,當根據所測定的溫度而求出的升溫速度成為50℃/s以上時,發出警報,而且進行將對加熱器101輸出的控制值設為0等限制。For example, in the past, when the specification related to the temperature change rate indicated by the heater manufacturer is 50° C./s, 50° C./s is set as the determination value of the temperature rise rate obtained from the measured temperature. Therefore, when the temperature increase rate obtained from the measured temperature becomes 50° C./s or more, an alarm is issued and restrictions such as setting the control value output to the heater 101 to 0 are performed.
這種異常避免控制中,例如加熱器101在實用上若為200℃以下,則即便是80℃/s加熱器也不會破損,即便是以加熱溫度低於200℃的低溫域使用時,也無法將升溫速度設為50℃/s以上。另一方面,這種加熱處理中,例如加快升溫速度的情況下可實現處理時間的縮短。In this abnormality avoidance control, for example, if the heater 101 is practically 200°C or less, the heater will not be damaged even if it is 80°C/s, even when it is used in a low temperature range where the heating temperature is lower than 200°C. It is not possible to set the temperature increase rate to 50°C/s or more. On the other hand, in this heat treatment, for example, when the temperature increase rate is increased, the treatment time can be shortened.
相對於此,根據實施方式1,例如若加熱溫度低於250℃,則即便升溫速度成為50℃/s以上,也不判斷為異常。另外,即便加熱溫度為250℃以上,若升溫速度成為50℃/s以上的時間為9秒以下,則也不判斷為異常。因此,根據實施方式1,可使升溫速度進一步加快,而可實現處理時間的縮短。例如,通過使用能以更高速的升溫速度使用的加熱器,從而即便在使用額定值的現有的控制中,也可使升溫速度進一步加快,而可實現處理時間的縮短。但是,這種高速升溫加熱器昂貴而導致成本上升。相對於此,根據實施方式1,無需使用昂貴的加熱器。如此,根據實施方式1,可在不導致加熱器破損的範圍內充分發揮加熱器101的能力。In contrast, according to Embodiment 1, if the heating temperature is lower than 250°C, for example, even if the temperature increase rate becomes 50°C/s or more, it is not judged as abnormal. In addition, even if the heating temperature is 250°C or higher, if the time for the temperature increase rate to become 50°C/s or higher is 9 seconds or less, it is not judged as abnormal. Therefore, according to the first embodiment, the temperature increase rate can be further increased, and the processing time can be shortened. For example, by using a heater that can be used at a higher rate of temperature increase, even in an existing control using a rated value, the rate of temperature increase can be further increased, and the processing time can be shortened. However, such high-speed heating heaters are expensive, which leads to an increase in cost. In contrast, according to the first embodiment, it is not necessary to use an expensive heater. In this way, according to the first embodiment, the ability of the heater 101 can be fully exhibited within a range that does not cause damage to the heater.
接下來,使用圖2的流程圖對實施方式1的溫度調節計的運行例(異常判斷方法)進行說明。Next, the operation example (abnormality determination method) of the temperature regulator of Embodiment 1 is demonstrated using the flowchart of FIG.
首先,步驟S101中,計算部103求出所測定的加熱器101的每單位時間的溫度上升變化作為升溫速度(第一步驟)。接著,步驟S102中,第一檢測部104檢測所測定的加熱器101的測定溫度超過保存在判定值記憶部120的預先設定的第一值(第二步驟)。當由第一檢測部104檢測到測定溫度超過第一值時(步驟S102的是(yes)),步驟S103中,第二檢測部105檢測所求出的升溫速度超過保存在判定值記憶部120的預先設定的第二值(第三步驟)。First, in step S101, the calculation unit 103 obtains the measured temperature rise change per unit time of the heater 101 as the temperature rise rate (first step). Next, in step S102, the
當由第二檢測部105檢測到升溫速度超過第二值時(步驟S103的是(yes)),步驟S104中,判斷第一測量部106是否已開始測量下述狀態持續的時間,即,檢測到升溫速度超過第二值的狀態。當未開始測量時間時(步驟S104的否(no)),步驟S105中,第一測量部106開始測量下述狀態持續的時間,即,檢測到測定溫度超過第一值且升溫速度超過第二值的狀態(第四步驟),進入步驟S106。另外,當已開始測量時間時(步驟S104的是(yes)),進入步驟S106。When the
接著,步驟S106中,判斷部107判斷測量的時間是否超過保存在判定值記憶部120的預先設定的第一計時器設定值(第一時間)(第五步驟)。當測量的時間超過第一計時器設定值時(步驟S106的是(yes)),步驟S107中,第一測量部106停止(結束)測量時間,步驟S108中,判斷部107判斷為異常(第五步驟)。此外,時間的測量在檢測到測定溫度超過第一值且檢測到升溫速度超過第二值的期間中持續(步驟S101~步驟S106)。當判斷部107判斷為異常時,步驟S109中進行異常處理(跳轉為異常時操作量,發出警報等)。異常處理後,維持所述狀態直到步驟S131中進行解除操作為止。Next, in step S106, the determination unit 107 determines whether the measured time exceeds the preset first timer setting value (first time) stored in the determination value storage unit 120 (fifth step). When the measured time exceeds the first timer setting value (yes in step S106), in step S107, the
實施方式2
接下來,參照圖3對本發明的實施方式2的溫度調節計進行說明。所述溫度調節計控制加熱器101的加熱能力,將控制物件的溫度控制為預先設定的設定溫度。所述溫度調節計包括測定部102、計算部103、第一檢測部104、第二檢測部105、第一測量部106、輸出部108、判定值記憶部120以及控制部121。這些部分與上文所述的實施方式1同樣。Embodiment 2
Next, a temperature regulator according to Embodiment 2 of the present invention will be described with reference to FIG. 3. The temperature regulator controls the heating capacity of the heater 101, and controls the temperature of the controlled object to a preset temperature. The temperature regulator includes a measurement unit 102, a calculation unit 103, a
實施方式2中還具備:預先設定的第三值,作為測定溫度的閾值,高於第一值;第一時間,當測定溫度為第一值以上且小於第三值時,適用作第一計時器設定值;以及第二時間,當測定溫度為第三值以上時,適用作第二計時器設定值。此外,這些第三值、第二計時器設定值(第二時間)也與第一值、第二值、第一計時器設定值(第一時間)同樣地保存在判定值記憶部120。實施方式2中,例如可設定100℃作為第一值,可設定50℃/秒作為第二值(升溫速度閾值),可設定250℃作為第三值。The second embodiment also has: a preset third value, which is a threshold value for measuring temperature, which is higher than the first value; the first time, when the measured temperature is greater than the first value and less than the third value, it is suitable for the first timer And the second time, when the measured temperature is above the third value, it is applicable as the second timer setting value. In addition, the third value and the second timer setting value (second time) are also stored in the judgment
另外,實施方式2中,當第一測量部106測量的時間超過第一計時器設定值,或者第二測量部110測量的時間超過預先設定的第二計時器設定值時,判斷部107a判斷為異常。實施方式2中,第一計時器設定值例如可設為3秒,第二計時器設定值可設為2秒。此外,也可將第一計時器設定值與第二時間設為相同的值。In addition, in Embodiment 2, when the time measured by the
實施方式2中,也與上文所述的實施方式1同樣地,可在不導致加熱器破損的範圍內充分發揮加熱器101的能力。另外,實施方式2中,可在兩個溫度域分別設定視為異常的判斷的時間基準。因此,例如可在更低的溫度域中,進一步延長視為異常的判斷時間的基準,例如可實現更迅速的升溫。此外,上文中,將測定溫度的判斷基準設為第一值與第三值兩者,但不限於此,也可將測定溫度的判斷基準設為三個以上。In the second embodiment, as in the first embodiment described above, the ability of the heater 101 can be fully exhibited within a range that does not cause damage to the heater. In addition, in the second embodiment, it is possible to set the time reference for the judgment regarded as an abnormality in each of the two temperature ranges. Therefore, for example, in a lower temperature range, the criterion for determining the abnormality time can be further extended, and for example, a more rapid temperature rise can be achieved.
