Field of the invention to which the invention belongs The present invention relates to a centralized control device for a display cabinet which is installed in a plurality of display cabinets such as a convenience store. 2. Prior art In the prior art, the applicant has previously proposed, as described in Japanese Patent Application Laid-Open No. 200 1 -25 8696, for such a centralized control device for display cabinets. The centralized control device of the display cabinet is provided with: a sub-machine control device for each of a plurality of display cabinets installed in the store, and data communication of each sub-machine control device, and integrated control of the operation of each display cabinet Master machine control device. Here, the master machine control device obtains operation information from each slave machine control device. On the other hand, the master machine control device transmits the operation control signal to the slave machine control device, so that the temperature in the warehouse can be controlled and maintained at a set temperature. In addition, when an abnormal temperature is obtained from the operation information of each slave control device, the operation stop signal is sent to the slave control device, thereby stopping the operation of each display cabinet. In addition, the master device has a display device for displaying the operation status. The display device displays various data such as the temperature inside the display cabinet, the set temperature, and the temperature difference on the screen of the display device. The operation of each display case is managed based on the display content. In addition, when changing the set temperature or abnormal set temperature in the display cabinet, the set temperature 値 can be input from the keyboard, so the setting data of each display cabinet can be written and changed, and the temperature in the storage can be arbitrarily changed. [Patent Document 1] Japanese Laid-Open Patent Publication No. 200 1 -25 8696 200420861 [Problems to be Solved by the Present Invention] However, the centralized control device of the display cabinet is a cooling-dedicated display cabinet, that is, 'for controlling the setting in the library' Showcases with one temperature or abnormal set temperature.

關於「庫內溫度警報設定畫面」，如第1 3圖所示地進行 畫面顯示。即，最上位顯示展示櫃群之系統名（肉•魚1) 及冷凍機之子機號碼（201)。又更下方係各展示櫃1，2之子 機號碼（No : 101〜116)被顯示在縱向，而各子機號碼之橫向 依序分別地顯示爲警報溫度（異常溫度）之上限設定値、到 達上限設定値後之遲延時間、警報溫度之下限設定値、到 達下限設定値後之遲延時間除霜時之判定的有無。在此 處，No ·· 101之H/C櫃1方面，雖然在上限設定値的顯示 領域上顯示「H/C」之文字標識，但這是顯示No ·· 101係爲 H/C櫃1。並且，在H/C櫃1中「遲延」「下限」「遲延」 「除霜時判定」之欄使用「-」之記號標識時，係未顯示這 些資料之意。而，最下段顯示的「警報條件設定」「下一 頁」「系統切換」係具有畫面切換開關功能之顯示。 關於警報資料，在顯示H/C櫃1之警報資料時，在第13 圖所示之No : 101的「上限」欄之「H/C」上點選。因而， 第13圖所示之「庫內溫度警報設定畫面」切換到第14圖 -19- 200420861 所示之「Η/C庫內溫度警報設定畫面」。在「Η/C庫內溫度 警報設定畫面」中，最上位顯示H/C櫃1之子機號碼（101)， 其下方分別上下顯示冷卻運轉資料及中溫運轉資料。各運 轉資料係與第Π圖之顯示方式同樣地、「上限」「遲延」 「下限」「遲延」「除霜時判定」橫向並列。而最下段顯 示的「庫內溫度警報設定」係具有畫面切換開關功能之顯 不 ° 以上，雖然已說明操作盤46之畫面461的各種畫面顯 不，但是從庫內溫度設定値、溫度差溫値、顯示校正値開 · 始，庫內溫度警報設定値等任何的設定亦可由操作輸入部 462等而設定變更。 依照本實施形態，在作爲以母機控制裝置4控制之子機 控制裝置5方面，除了冷卻櫃控制裝置2 1及冷凍機控制裝 置3 1以外，再加上Η/C櫃1之Η/C櫃控制裝置1 1。從而， Η/C櫃控制裝置1 1與母機控制裝置4之間進行運轉資料的 發收訊，Η/C櫃1亦可利用母機控制裝置4進行集中控制， 因此在冷卻運轉及中溫運轉切換之時，可使庫內溫度設定 H 或異常溫度設定（警報溫度設定）自動地切換而對應於各運 轉，因此使操作性提高。 並且，構成Η/C櫃控制裝置11的冷卻控制裝置1 2及加 溫控制裝置1 3之中，冷卻控制裝置1 2係配置與冷卻櫃控 制裝置2 1及冷凍機控制裝置3 1同一之供電電路，另一方 面，加溫控制裝置13則配置有以Η/C櫃1之運轉開關‘81 做ON · OFF控制之另一系統的供電電路。 但是，將Η/C櫃1從加溫運轉切換到冷卻運轉（中溫運轉 -20- 200420861 或冷卻運轉）之時，並且，從冷卻運轉切換到加溫運轉之 時，將運轉開關81 OFF，而實施使Η/C櫃1返回到環境溫 度的操作，其後，進行冷卻運轉或加溫運轉。 因而，在運轉切換之時，亦如前所述，並未停止對冷卻 控制裝置1 2的供電，因此母機控制裝置4不會判定爲通訊 異常。 並且，母機控制裝置4之操作盤46，在「庫內溫度設定 畫面」及「庫內溫度警報設定畫面」，使用「H/C」之標識 而顯示H/C櫃1，並且，點選這些畫面之中的預定地點時， 鲁 可顯示另外畫面之「H/C庫內溫度設定畫面」或「H/C庫內 溫度警報設定畫面」。因此，即使具有很多個冷卻櫃2因 而使畫面空間不足之時，亦可毫無困難地將H/C櫃1的運 轉資料顯示。 【發明之效果】 如以上所說明者，依照本發明，加溫·冷卻展示櫃的之 加溫運轉資料、中溫運轉資料、冷卻運轉資料、及運轉停 止資料被發訊到該母機控制裝置，並可從該母機控制裝置 · 將對應於各種運轉資料的運轉控制資料發訊到子機控制裝 置，因此亦可集中控制加溫·冷卻展示櫃。並且，在加溫· 冷卻展示櫃中，即使運轉開關被切斷時，亦可對冷卻控制 裝置繼續供電，因此警報不會從母機控制裝置發出。因而’ 不會有不需要的異常警報，故可提高展示櫃之管理性。 五__、圖式簡單說明 第1圖係子機控制裝置與母機控制裝置之結線電路圖； 第2圖係顯示母機控制裝置與子機控制裝置之資料通訊 -21- 200420861 的功能方塊圖； 第3圖係顯示母機控制裝置之隨機取存記憶體（RAM)之 記憶資訊的方塊圖；

Here, each of the cooling cabinet control device 21 and the refrigerator control device 31 has a separate power switch (not shown) in the same manner as in the prior art. On the other hand, the H / C cabinet control device 11 is a cooling control device 12 and the 2 side is often connected to a power source. On the other hand, the heating control device 13 is connected to the H / C cabinet 1 operation switch 8 1. Therefore, even when the switch 8 10F is operated, the power to the cooling control device 12 is not turned off. Next, the H / C cabinet 1 series performs heating operation, intermediate temperature operation (in the temperature range of the storeroom about 10 ° C ~ 16 ° C), and cooling operation (in the temperature range of the storeroom 5 ° C ~ 6 ° C left- 14-200420861 Right) Refer to Figures 6 and 7 to explain the switching circuit for each operation. The operation switching circuit is connected to the power supply 7 by a two-stage operation switch 8 and a relay 82. The switch 2 has 3 switching contacts 831a ~ 831c, 832a ~ 832c, and a cooling control device 12 in series. connection. In addition, the power source η has another wiring connected to the series wiring and connects the operation switch 8 1, the relay 8 2, and the switch 8 3 in a circuitous manner to the switch 8 3 and the cooling control device 12. . In this operation switching circuit, each of the switching contacts 831a to 83lc, 832a to 832c of the switching switch 83, the switching contacts 83la, 8 32a are contacts for detecting heating operation, and the like It is open. The switching contacts 8 3 1 b and 8 3 2 b are contacts for detecting medium temperature operation, and they are connected to the medium temperature input terminal 128 of the cooling control device 12. Switching contacts 831c, 83 2c are contacts for cooling operation detection, and they are connected to the cooling input terminal 丨 29 of the cooling control device 丨 2. In addition, four single-pole double-throw type relay contacts 821 to 824 of the relay 82 are provided on the wiring of the operation switch 81, the relay 82, and the changeover switch 83. Here, 'relay contacts 821 to 824, the relay contacts 8 2 1, 8 2 3 connected to one side of the normally closed (NC) switching terminals 8 2 1 a, 8 2 3 a are connected to the medium temperature Switching contacts 831b, 832b for operation detection.

Here, when the changeover switch 83 is switched to the changeover contacts 83la, 8 3 2a, it becomes an open circuit. Therefore, no voltage is applied to the intermediate temperature input terminal 128 and the cooling input terminal 129. Therefore, the cooling control device 12 can determine to switch to the warming operation. When the changeover switch 83 is switched to the switching contacts 831b, 8 3 2b, a voltage is applied to the intermediate temperature input terminal 1 28, and the voltage is not applied to the cooling input terminal 1 29. Therefore, the cooling control device 12 can determine to switch to the intermediate temperature operation. When the changeover switch 8 3 is switched to the changeover contacts 83 lc, 8 3 2c, a voltage is applied to the cooling input terminal 129, and the voltage is not applied to the intermediate temperature input terminal 128. Therefore, the cooling control device 12 can determine to switch to the cooling operation. Therefore, by using the operation switching circuit, the cooling control device 12 can determine operation stop, heating operation, intermediate temperature operation, and cooling operation. Next, the operation determination and signaling processing of the cooling control device 12 of the H / C cabinet 1 will be described with reference to FIG. 8. That is, when the operation switch 81 and the changeover switch 83 are operated (S1), it is determined that a warming operation signal is input (S2), a medium temperature operation signal is input (S3), a cooling operation signal is input (S4), or the operation is stopped. The signal is input (S5). When a warming operation signal is input here, it is determined as a warming operation (S6). When the intermediate temperature operation signal is input, it is judged as intermediate temperature operation (S7). When the cooling operation signal is input, it is determined as the cooling operation (S 8). When the operation stop signal is input, it is determined that the operation is stopped (S9). Then, the cooling control device 12 sends the heating operation data, the intermediate temperature operation data, the cooling operation data, and the operation stop data to the parent machine control device 4 via the communication control unit 12 (S10 to S13). However, although not shown, the signal processing of the cooling cabinet control device 21 and the refrigerator control device 31 is implemented by the same processor as that of the prior art 200420861. That is, the cooling operation data is transmitted from the cooling cabinet control device 21 to the parent machine control device 4, and the start-stop data is transmitted from the refrigerator control device 31 to the parent machine control device 4. Next, referring to FIG. 9, a signal processing process from the master control device 4 to the cooling control device 12 of the H / C cabinet 1 will be described. Here, it is judged that the cooling control device 12 of the H / C cabinet 1 receives a medium temperature operation signal or a cooling operation signal (S 101, S 102). When the intermediate temperature operation signal is received, the operation control data for intermediate temperature operation, such as the intermediate temperature operation setting temperature data, the intermediate temperature operation abnormal temperature data, and the like are transmitted to the cooling control device 12 (S 103). On the other hand, when receiving the cooling operation signal, the operation control data for cooling operation such as the cooling operation set temperature data, cooling operation abnormal temperature data, etc. are transmitted to the cooling control device 12 (S104). This information is transmitted to perform cooling operation. On the other hand, the 'master machine control device 4 did not send data from the master machine control device 4 when receiving the heating operation data and the operation stop data. Then, heating operation is continued in the H / C cabinet 1 by the heating control device 13 or the operation is stopped. Next, the screen 4 6 1 which is the display part of the master machine control device 4 is displayed as follows. The "operation status screen" is a screen display as shown in Fig. 10. That is, the upper 3 segments display the time of day, the temperature and humidity inside and outside the store, and the lower part displays the operation setting or defrost setting. The system name (refrigeration 1) of the display cabinet group and the subunit number (201) of the freezer are displayed further below. Further below, the handset numbers (No: 1101 ~ 116) of each display cabinet 1 and 2 are displayed below, and the temperature inside the display cabinets 2 and 2 sent from the handset control device 5 are displayed further below. Here, although the text mark “r H〇t” is displayed on the display area of the temperature in the warehouse of no: 101, 200420861 This is the display of No: 101 / C cabinet 1 is performing heating operation. In addition, although the symbol "..." is displayed on the display area of the temperature in the warehouse of No: 102, the cooling cabinet 2 showing No: 102 is stopped. In addition, the "normal setting selection", "display selection", and "system switching" displayed at the bottom are displays with a screen switch function. The "internal temperature setting screen" is displayed on the screen as shown in Fig. 11. That is, the system name of the display cabinet group (refrigeration 1) and the number of the refrigerator (201) of the refrigerator are displayed at the top, and the number of the child (No: 101 ~ 116) of each display cabinet 1,2 is displayed below, and from the bottom The temperature inside the display cabinets 1 and 2 sent from the slave control device 5. Here, although the text mark "Η / C" is displayed on the display area of the temperature in the library No. 101, this is the display No. 101 for the Η / C cabinet 1. The set temperature of each display cabinet 丨, 2 is displayed further below, and the temperature difference temperature is displayed below, and the correction of the displayed temperature is displayed below, and the night temperature correction is not displayed below. The number of display cabinets with the system name (refrigeration 1) shown in the figure is a large number of 15 (No: 101 ~ 116). Therefore, these display data are displayed in two sections. Here, No. 101's H / C cabinet 1 side 'is displayed on a separate screen, so the display area of "Set temperature", "Diff", "No correction", and "Night correction" are blank. In addition, the "normal setting selection" and "system switching" displayed at the bottom are displays with a screen switch function. When the operation data of Η / C cabinet 1 is displayed, click on the set temperature of No: 101 shown in the u figure ~ the place indicated by the dotted four corners of the night correction bar (picture u). Therefore, the 1st The "r temperature setting screen in the library" shown in Figure 1 will switch to the "Η / C temperature setting screen in the library". In the "h / C temperature setting screen", the topmost display shows the system name of the display cabinet group (refrigeration 丨) and the subunit number (201) of the freezer 200420861, and the subunit number of the H / c cabinet 1 ( No · · iOl), the current operation mode (heating operation, intermediate temperature operation, cooling operation, and operation stop) of H / C cabinet 1 is set below it. 'H / C sent from slave control device 5 is displayed below it. The temperature in the cabinet of the cabinet 1. Below it is a point for selecting when changing the operation mode, so that cooling operation or medium temperature operation can be performed. Further below, the same "set temperature", "DIFF", "display correction", and "night correction" as shown in Fig. 11 are displayed. When you click on the "Internal temperature setting" displayed at the bottom, you can switch to the "Internal temperature setting screen" in Figure 11. The "internal temperature alarm setting screen" is displayed on the screen as shown in Fig. 13. That is, the system name (meat and fish 1) of the display cabinet group and the sub unit number (201) of the freezer are displayed at the top. Further below, the display unit numbers (No: 101 ~ 116) of each display cabinet 1 and 2 are displayed in the vertical direction, and the horizontal direction of each display unit number is displayed as the upper limit setting of the alarm temperature (abnormal temperature). The delay time after the upper limit setting, the lower limit setting of the alarm temperature, and the delay time after reaching the lower limit setting. Here, in the H / C cabinet 1 of No. · 101, although the text mark "H / C" is displayed on the display area of the upper limit setting 値, this is the display No. · 101 is H / C cabinet 1 . In addition, when using the "-" mark in the "Delay", "Lower Limit", "Delay", and "Defrost Judgment" columns in H / C Cabinet 1, these data are not displayed. In addition, the "Alarm condition setting", "Next page", and "System switching" displayed at the bottom are displays with a screen switch function. For the alarm data, when displaying the alarm data of H / C cabinet 1, click on "H / C" in the "Upper Limit" column of No: 101 shown in Figure 13. Therefore, the "internal temperature alarm setting screen" shown in Fig. 13 is switched to the "Η / C in-room temperature alarm setting screen" shown in Fig. 14 -19- 200420861. In the "Η / C temperature alarm setting screen", the slave unit number (101) of H / C cabinet 1 is displayed at the highest position, and the cooling operation data and intermediate temperature operation data are displayed above and below. Each operation data is horizontally juxtaposed with the upper limit, the delay, the lower limit, the delay, and the determination during defrosting in the same manner as shown in Fig. Π. The "Alarm temperature alarm setting" displayed at the bottom is the display with the screen switch function. Although it has been explained that the various screens of the screen 461 of the operation panel 46 are displayed, the temperature setting in the library and the temperature difference値, display calibration 値 starts and starts, and any setting such as temperature alarm setting in the library can also be changed by operating the input unit 462 and other settings. According to this embodiment, in addition to the cooling cabinet control device 21 and the refrigerating machine control device 3 1 as the slave device control device 5 controlled by the master machine control device 4, the Η / C cabinet control of the Η / C cabinet 1 is also added. Device 1 1. Therefore, the operation data is transmitted and received between the Η / C cabinet control device 11 and the master machine control device 4. The Η / C cabinet 1 can also be controlled centrally by the master machine control device 4, so switching between cooling operation and intermediate temperature operation At this time, the temperature setting H or the abnormal temperature setting (alarm temperature setting) in the room can be automatically switched to correspond to each operation, thereby improving the operability. In addition, among the cooling control device 12 and the heating control device 13 constituting the Η / C cabinet control device 11, the cooling control device 12 is provided with the same power supply as the cooling cabinet control device 21 and the refrigerator control device 31. On the other hand, the heating control device 13 is provided with a power supply circuit of another system controlled by the ON / OFF operation switch '81 of the Η / C cabinet 1. However, when the Η / C cabinet 1 is switched from heating operation to cooling operation (intermediate temperature operation-20-200420861 or cooling operation), and when switching from cooling operation to heating operation, the operation switch 81 is turned off. The operation of returning the Η / C cabinet 1 to the ambient temperature is performed, and thereafter, a cooling operation or a heating operation is performed. Therefore, when the operation is switched, as described above, the power supply to the cooling control device 12 is not stopped. Therefore, the master device control device 4 does not determine that the communication is abnormal. In addition, the operation panel 46 of the master machine control device 4 displays the H / C cabinet 1 using the "H / C" mark on the "in-room temperature setting screen" and "in-room temperature alarm setting screen", and clicks these At the predetermined place on the screen, Luco can display the “H / C temperature setting screen” or “H / C temperature alarm setting screen” on another screen. Therefore, even when there are many cooling cabinets 2 and the screen space is insufficient, the operation data of the H / C cabinet 1 can be displayed without difficulty. [Effects of the Invention] As explained above, according to the present invention, the heating operation data, the intermediate temperature operation data, the cooling operation data, and the operation stop data of the heating and cooling display cabinet are transmitted to the master machine control device, From this master machine control device, it is possible to send operation control data corresponding to various operation data to the slave machine control device, so it can also centrally control the heating and cooling display cabinets. In addition, in the heating and cooling display cabinet, even if the operation switch is turned off, power can be continuously supplied to the cooling control device, so the alarm is not issued from the master control device. Therefore, there is no unnecessary abnormal alarm, so the management of the display cabinet can be improved. Five __, the diagram is briefly explained.
