Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning control, and in particular to a control system, a control device and a wiring prompt circuit of a wire controller. Background Art

[0002] Typically, certain control signals are defined as signal instructions for the wired controller, such as Y1, Y2, W, and O. When the wired controller inputs these signal instructions to controllers such as the fan control board, the control board of the air conditioner's indoor unit, and the control board of the air conditioner's outdoor unit, the controller can drive circuits such as the compressor, valve components, and auxiliary heating circuits to achieve corresponding functions such as cooling or heating.

[0003] Currently, the power supply terminal of a wired controller receives AC power, and the common terminal is grounded. Because the potential change of the signal command output by some wired controllers is the same as the R terminal of their own power supply terminal, if the R terminal and the common terminal C of the power supply terminal of these wired controllers are reversed, the potential of the signal command output by these wired controllers will be equal to ground level. Since the output potential of these wired controllers is also equal to ground level or is floating when they are not outputting signal commands, no potential difference can be formed. In other words, the controller connected to these wired controllers cannot distinguish whether these wired controllers are outputting signal commands. As a result, the controller is always in standby mode and will not report any fault codes. As a result, assemblers cannot directly determine whether the R terminal and the common terminal C of the power supply terminal of these wired controllers are reversed.

[0004] Therefore, how to inform assemblers whether the two ends of the power supply interfaces of these wired controllers are reversely connected is a technical problem that needs to be solved urgently. Summary of the Invention

In the present application, relational terms such as first and second, etc. are only used to distinguish an entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. And the term "comprise", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only include those elements, but also include other elements not clearly listed, or also include elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the statement "comprising one..." do not exclude that there are other identical elements in the process, method, article or equipment including the elements.

[0063] In order to remind the assembler whether the two ends of the power supply interface of these wire controllers are reversely connected, the embodiment of the present application provides a wiring reminder circuit for the wire controller. The specific structure can be found in Figures 1-8 ( Figures 1-8Only five prompting devices 10 , five rectifying branches 20 , and a wire controller 01 having five signal output terminals G, Y1 , O, W1 , and W2 are used as an example for demonstration. Specifically, the system includes: at least one prompting device 10 and at least one rectifying branch 20 .

[0064] The power supply interface of the wired controller 01 has a grounded common terminal C and an AC power supply terminal R. In practical applications, the AC power is usually 24VAC, which is not specifically limited here and can be set according to the actual operation of the wiring prompt circuit.

[0065] Each prompt device 10 is connected in series with a rectifier branch 20; the first end of the series branch is connected to a signal output end of the wire controller 01 to receive signal instructions; the second end of the series branch is connected to the power supply terminal R or the common terminal C of the power supply interface of the wire controller 01.

[0066] The potential change of the signal instruction output by the wire controller 01 is the same as the power supply terminal R of the power supply interface of the wire controller 01 .

[0067] If the number of prompting devices 10 and the number of rectifying branches 20 is greater than 1, the second end of each series branch formed by each prompting device 10 and each rectifying branch 20 is connected to the same end of the power supply interface of the wired controller 01. Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 As shown, the second ends of the five series branches formed by the five prompting devices 10 and the five rectifier branches 20 are all connected to the common terminal C of the power supply interface of the wire controller 01. Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 As shown, the second ends of the five series branches formed by the five prompting devices 10 and the five rectifying branches 20 are all connected to the power supply terminal R of the power supply interface of the wired controller 01.

[0068] In a specific example, Figure 1 or Figure 2 As shown, the first end of each prompt device 10 is connected to a signal output end of the wired controller 01, and the second end of each prompt device 10 is connected to an input end of a rectifier branch 20. Figure 1 As shown, the output end of each rectifier branch 20 is connected to the common terminal C of the power supply interface of the wire controller 01, as shown in FIG. Figure 2 As shown, the output end of each rectifier branch 20 is connected to the power supply end R of the power supply interface of the wired controller 01 .

[0069] In another specific example, Figure 3 or Figure 4As shown, the first end of each prompt device 10 is connected to a signal output end of the wired controller 01, and the second end of each prompt device 10 is connected to an output end of a rectifier branch 20. Figure 3 As shown, the input end of each rectifier branch 20 is connected to the common terminal C of the power supply interface of the wire controller 01, as shown in FIG. Figure 4 As shown, the input end of each rectifier branch 20 is connected to the power supply terminal R of the power supply interface of the wired controller 01.

[0070] In another specific example, Figure 5 or Figure 6 As shown, the first end of each prompt device 10 is connected to the output end of a rectifier branch 20, and the input end of each rectifier branch 20 is connected to a signal output end of the wired controller 01. Figure 5 As shown, the second end of each prompt device 10 is connected to the common terminal C of the power supply interface of the wire controller 01, as shown in FIG. Figure 6 As shown, the second end of each prompt device 10 is connected to the power supply terminal R of the power supply interface of the wired controller 01.

[0071] In another specific example, Figure 7 or Figure 8 As shown, the first end of each prompt device 10 is connected to the input end of a rectifier branch 20, and the output end of each rectifier branch 20 is connected to a signal output end of the wired controller 01. Figure 7 As shown, the second end of each prompt device 10 is connected to the common terminal C of the power supply interface of the wire controller 01, as shown in FIG. Figure 8 As shown, the second end of each prompt device 10 is connected to the power supply terminal R of the power supply interface of the wired controller 01.

[0072] The above four examples show four connection methods of the prompt device 10 and the rectifier branch 20. No specific limitation is made here and it can be determined according to the specific situation. All of them are within the scope of protection of this application.

[0073] Each prompting device 10 can issue a prompt when it is powered.

[0074] Since the potential change of the signal instruction output by the wire controller 01 is the same as the power supply terminal R pole of its own power supply interface, if the two poles of the power supply interface of the wire controller 01 are not reversed, that is, the power supply terminal R pole of the power supply interface of the wire controller 01 receives alternating current and the common terminal C pole is grounded, then the potential change of the signal instruction output by the wire controller 01 is the same as the above-mentioned alternating current. If the two poles of the power supply interface of the wire controller 01 are reversed, that is, the common terminal C pole of the power supply interface of the wire controller 01 receives the above-mentioned alternating current and the power supply terminal R pole is grounded, then the potential of the signal instruction output by the wire controller 01 is equal to the ground level.

[0075] by Figure 1 For example, if the power supply R and common C terminals of the wired controller 01's power supply interface are reversed, that is, if the signal command output by the wired controller 01 is at ground level, then if the wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to ground level, and the potential of the second end of the series branch formed is equal to ground level. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered. If the power supply R and common C terminals of the wired controller 01's power supply interface are not reversed, that is, if the potential change of the signal command output by the wired controller 01 is the same as that of the AC power supply, then if the wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to that of the AC power supply, and the potential of the second end of the series branch formed is equal to ground level. Therefore, the rectifier branch 20 rectifies the AC power supply, and the prompt device 10 is powered during the positive half-cycle of the AC power supply. Since the frequency of the AC power supply is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation.

[0076] by Figure 2 For example, if the power supply R and common C terminals of the power supply interface of wired controller 01 are reversed, that is, if the potential of the signal command output by wired controller 01 is equal to ground, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to ground, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 rectifies the AC current, so that the prompt device 10 is powered when the AC current is in the negative half cycle. Since the frequency of the AC current is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation. If the power supply R and common C terminals of the power supply interface of wired controller 01 are not reversed, that is, if the potential change of the signal command output by wired controller 01 is the same as that of the AC current, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to the AC current, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered.

[0077] by Figure 3For example, if the power supply R and common C terminals of the power supply interface of wired controller 01 are reversed, that is, if the potential of the signal command output by wired controller 01 is equal to ground, if wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to ground, and the potential of the second end of the series branch formed is equal to ground. Therefore, rectifier branch 20 does not perform rectification, and thus prompting device 10 is not powered. If the power supply R and common C terminals of the power supply interface of wired controller 01 are not reversed, that is, if the potential change of the signal command output by wired controller 01 is the same as that of the AC power supply, if wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to the AC power supply, and the potential of the second end of the series branch formed is equal to ground. Therefore, rectifier branch 20 rectifies the AC power supply, and thus prompting device 10 is powered during the negative half cycle of the AC power supply. Since the frequency of the AC power supply is relatively high, it can be roughly assumed that the prompting device 10 is powered in this situation.

[0078] by Figure 4 For example, if the power supply R and common C terminals of the power supply interface of wired controller 01 are reversed, that is, if the potential of the signal command output by wired controller 01 is equal to ground, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to ground, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 rectifies the AC current, so that the prompt device 10 is powered when the AC current is in the positive half cycle. Since the frequency of the AC current is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation. If the power supply R and common C terminals of the power supply interface of wired controller 01 are not reversed, that is, if the potential change of the signal command output by wired controller 01 is the same as that of the AC current, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to the AC current, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered.

[0079] by Figure 5For example, if the power supply R and common C terminals of the wired controller 01's power supply interface are reversed, that is, if the signal command output by the wired controller 01 is at ground level, then if the wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to ground level, and the potential of the second end of the series branch formed is equal to ground level. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered. If the power supply R and common C terminals of the wired controller 01's power supply interface are not reversed, that is, if the potential change of the signal command output by the wired controller 01 is the same as that of the AC power supply, then if the wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to that of the AC power supply, and the potential of the second end of the series branch formed is equal to ground level. Therefore, the rectifier branch 20 rectifies the AC power supply, and the prompt device 10 is powered during the positive half-cycle of the AC power supply. Since the frequency of the AC power supply is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation.

[0080] by Figure 6 For example, if the power supply R and common C terminals of the power supply interface of wired controller 01 are reversed, that is, if the potential of the signal command output by wired controller 01 is equal to ground, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to ground, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 rectifies the AC current, so that the prompt device 10 is powered when the AC current is in the negative half cycle. Since the frequency of the AC current is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation. If the power supply R and common C terminals of the power supply interface of wired controller 01 are not reversed, that is, if the potential change of the signal command output by wired controller 01 is the same as that of the AC current, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to the AC current, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered.

[0081] by Figure 7For example, if the power supply R and common C terminals of the wired controller 01's power supply interface are reversed, that is, if the signal command output by the wired controller 01 is at ground level, then if the wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to ground level, and the potential of the second end of the series branch formed is equal to ground level. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered. If the power supply R and common C terminals of the wired controller 01's power supply interface are not reversed, that is, if the potential change of the signal command output by the wired controller 01 is the same as that of the AC power supply, then if the wired controller 01 outputs the signal command, the potential of the first end of the series branch formed is equal to that of the AC power supply, and the potential of the second end of the series branch formed is equal to ground level. Therefore, the rectifier branch 20 rectifies the AC power supply, and the prompt device 10 is powered when the AC power supply is in the negative half cycle. Since the frequency of the AC power supply is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation.

[0082] by Figure 8 For example, if the power supply R and common C terminals of the power supply interface of wired controller 01 are reversed, that is, if the potential of the signal command output by wired controller 01 is equal to ground, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to ground, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 rectifies the AC current, so that the prompt device 10 is powered when the AC current is in the positive half cycle. Since the frequency of the AC current is relatively high, it can be roughly assumed that the prompt device 10 is powered in this situation. If the power supply R and common C terminals of the power supply interface of wired controller 01 are not reversed, that is, if the potential change of the signal command output by wired controller 01 is the same as that of the AC current, if wired controller 01 outputs the signal command, the potential of the first terminal of the series branch formed is equal to the AC current, and the potential of the second terminal of the series branch formed is equal to the AC current. Therefore, the rectifier branch 20 does not perform rectification, and the prompt device 10 is not powered.

[0083] To sum up, when the online controller 01 outputs a signal instruction, the rectifier branch 20 either performs rectification when the two ends of the power supply interface of the online controller 01 are reversed, and does not perform rectification when the two ends of the power supply interface of the online controller 01 are not reversed; the rectifier branch 20 either performs rectification when the two ends of the power supply interface of the online controller 01 are not reversed, and does not perform rectification when the two ends of the power supply interface of the online controller 01 are reversed. Therefore, the prompt device 10 is powered in one of the above two situations and is not powered in the other situation, that is, the prompt device 10 issues a prompt in one of the above two situations and does not issue a prompt in the other situation. Therefore, the wiring prompt circuit of the online controller provided in this application can prompt the assembler whether the two poles of the power supply interface of these online controllers are reversed through the different reactions of the prompt device 10 in different situations.

[0084] Another embodiment of the present application provides another implementation of the wiring prompt circuit of the wired controller. The specific structure can be found in Figures 9-11 ( Figures 9-11 Only in Figure 1 or Figure 12-14 ( Figure 12-14 Only in Figure 4 ), this embodiment, based on any of the above embodiments, further includes: at least one current limiting resistor Rx.

[0085] Each series branch is also connected in series with a current limiting resistor Rx.

[0086] In a specific example, if Figure 9 or Figure 12 As shown, a current-limiting resistor Rx is provided between each prompting device 10 and each rectifying branch 20 .

[0087] In another specific example, Figure 10 or Figure 13 As shown, a current limiting resistor Rx is provided between each prompt device 10 and the corresponding signal output terminal of the wired controller 01 .

[0088] In another specific example, Figure 11 or Figure 14 As shown, a current limiting resistor Rx is provided between each rectifier branch 20 and the corresponding end of the power supply interface of the wired controller 01 .

[0089] The above three examples only show three ways to set the current limiting resistor Rx. In practical applications, including but not limited to these, no specific limitations are made here and can be determined according to specific circumstances. They are all within the scope of protection of this application.

[0090] In this embodiment, by providing the current-limiting resistor Rx, the current flowing through the prompting device 10 and the rectifying branch 20 can be limited, thereby reducing the possibility of damaging the prompting device 10 and the rectifying branch 20.

[0091] Another embodiment of the present application provides another implementation of the wiring prompt circuit of the wired controller. The specific structure can be found in Figure 15 ( Figure 15 Only in Figure 11 The difference between this embodiment and the previous embodiment is that:

[0092] In this embodiment, if the number of current limiting resistors Rx is greater than 1, at least two current limiting resistors Rx are combined into one. Figure 15 As shown, all current limiting resistors Rx are combined into one.

[0093] In this embodiment, by combining at least two current limiting resistors Rx into one, the number of current limiting resistors Rx is reduced, thereby reducing the wiring difficulty of the wiring prompt circuit of the wired controller and thus reducing the overall cost of the wiring prompt circuit of the wired controller.

[0094] Another embodiment of the present application provides another implementation of the wiring prompt circuit of the wired controller. The specific structure can be found in Figure 16 , this embodiment differs from any of the above embodiments in that:

[0095] In this embodiment, if the number of prompting devices 10 is greater than 1, at least two prompting devices 10 are merged into one. Figure 16 As shown, all prompting devices 10 are combined into one.

[0096] In this embodiment, by merging at least two prompting devices 10 into one, the number of prompting devices 10 is reduced, thereby reducing the wiring difficulty of the wiring prompt circuit of the wired controller and thus reducing the overall cost of the wiring prompt circuit of the wired controller.

[0097] Another embodiment of the present application provides another implementation of the wiring prompt circuit of the wired controller. The specific structure can be found in Figure 17 (Only in Figure 9 ), this embodiment differs from any of the above embodiments in that:

[0098] In this embodiment, if the number of the rectifier branches 20 is greater than 1, at least two rectifier branches 20 are merged into one. Figure 17 As shown, all the rectifier branches 20 are merged into one.

[0099] In this embodiment, by merging at least two rectifier branches 20 into one, the number of rectifier branches 20 is reduced, thereby reducing the wiring difficulty of the wiring prompt circuit of the wired controller and thus reducing the overall cost of the wiring prompt circuit of the wired controller.

[0100] Another embodiment of the present application provides another implementation of a wiring prompt circuit for a wired controller. This implementation differs from any of the above implementations in that:

[0101] In this embodiment, the prompting device 10 may be a device that provides prompts through light and / or sound, such as an LED, or a device that generates sound when powered.

[0102] The above is only a specific implementation of the prompt device 10. In practical applications, including but not limited to this, any device that can issue a prompt when powered is within the scope of protection of this application.

[0103] Another embodiment of the present application provides a specific implementation of the rectifier branch 20. The structure of this implementation can be found in Figures 1-17 , this embodiment specifically includes: at least one diode.

[0104] If the number of diodes is greater than 1, the diodes are connected in series in the same direction, the anode of the series branch formed serves as the input end of the rectifier branch 20 , and the cathode of the series branch formed serves as the output end of the rectifier branch 20 .

[0105] If the number of diodes is equal to 1, the anode of the diode serves as the input end of the rectifier branch 20, and the cathode of the diode serves as the output end of the rectifier branch 20. For example, Figures 1-17 D in.

[0106] In this embodiment, the diode is used for rectification, thus simplifying the structure of the rectification branch 20 , thereby reducing the cost of the rectification branch 20 and further reducing the overall cost of the wiring prompt circuit.

[0107] The above is only a specific implementation of the rectifier branch 20. In practical applications, including but not limited to this, as long as the circuit can achieve the rectification function, it is within the protection scope of this application. No specific limitation is made here and it can be determined according to the specific situation.

[0108] Another embodiment of the present application provides a control system, the specific structure of which can be found in Figure 18 ( Figure 18 In the figure, only the wire controller 01 having five signal output terminals G, Y1, O, W1, and W2 and the control unit 02 having five signal input terminals G, Y, O, W1, and W2 are used for demonstration. The figure specifically includes: the wire controller 01, the air conditioner control unit 02, and the wiring prompt circuit 06.

[0109] The power supply interface of the wire controller 01 has a grounded common terminal C and a power supply terminal R connected to the alternating current.

[0110] The wiring prompt circuit 06 includes at least one prompt device 10 and at least one rectifier branch 20. The connection relationship between the wiring prompt circuit 06, the wired controller 01, and the air conditioner control unit 02 is as follows:

[0111] Each prompting device 10 is connected in series with a rectifier branch 20. The first end of the series branch is connected to a signal output terminal of the wired controller 01 to receive signal instructions. The second end of the series branch is connected to the power supply terminal R or the common terminal C of the power supply interface of the wired controller 01. The potential change of the signal instruction is the same as that of the power supply terminal R of the power supply interface of the wired controller 01.

[0112] Each prompting device 10 can issue a prompt when it is powered.

[0113] If the number of prompting devices 10 and rectifying branches 20 is greater than 1, the second ends of the series branches formed by the prompting devices 10 and the rectifying branches 20 are all connected to the same end of the power supply interface of the wired controller 01 .

[0114] It should be noted that the series branches formed by the prompting devices 10 and the rectifying branches 20 have been described in detail in the above embodiments and will not be repeated here.

[0115] Each signal output terminal of the wire controller 01 is connected to each signal input terminal of the control unit 02 in a one-to-one correspondence. Figure 18 As shown, the signal output terminal G of the wire controller 01 is connected to the signal input terminal G of the control unit 02, the signal output terminal Y1 of the wire controller 01 is connected to the signal input terminal Y of the control unit 02, the signal output terminal O of the wire controller 01 is connected to the signal input terminal O of the control unit 02, the signal output terminal W1 of the wire controller 01 is connected to the signal input terminal W1 of the control unit 02, and the signal output terminal W2 of the wire controller 01 is connected to the signal input terminal W2 of the control unit 02.

[0116] In this embodiment, since one end of each series branch in the wiring prompt circuit 06 is connected to a signal output end of the wired controller 01, the control system can also prompt the assembler whether the two poles of the power supply interface of these wired controllers 01 are reversed.

[0117] Another embodiment of the present application provides another implementation of the control system. The difference between this implementation and the above implementation is that: in this implementation, Figure 18As shown, the power supply terminal R pole of the power supply interface of the wire controller 01 is connected to the power supply terminal R pole of the power supply interface of the control unit 02, and the common terminal C pole of the power supply interface of the wire controller 01 is connected to the common terminal C pole of the power supply interface of the control unit 02, that is, the power supply interface of the wire controller 01 is connected to the power supply interface of the control unit 02, that is, the wire controller 01 and the control unit 02 draw power from the same location.

[0118] In this embodiment, since the wire controller 01 and the control unit 02 draw power from the same location, the connection relationship between the various components in the control system can be simplified, thereby reducing the connection difficulty of the control system and thus reducing the overall cost of the control system.

[0119] The above is only one way of drawing power for the wire controller 01 and the control unit 02. In practical applications, including but not limited to this, for example, the wire controller 01 and the control unit 02 can each draw power independently. No specific limitation is made here and it can be determined according to the specific situation, all of which are within the scope of protection of this application.

[0120] Another embodiment of the present application provides a specific implementation of the control unit 02, and its specific structure is as follows: Figure 18 As shown, it specifically includes: an indoor control panel 04 and an outdoor control panel 05 of the air conditioner.

[0121] Each signal input terminal of the indoor control board 04 and each first signal input terminal of the outdoor control board 05 are respectively used as each signal input terminal of the control unit 02. Figure 18 As shown, G of the indoor control board 04 is connected to G of the wire controller 01 via a wiring prompt circuit 06, O of the indoor control board 04 is connected to O of the wire controller 01 via a wiring prompt circuit 06, W1 of the indoor control board 04 is connected to W1 of the wire controller 01 via a wiring prompt circuit 06, W2 of the indoor control board 04 is connected to W2 of the wire controller 01 via a wiring prompt circuit 06, and Y of the outdoor control board 05 is connected to Y1 of the wire controller 01 via a wiring prompt circuit 06.

[0122] Each signal output terminal of the indoor control board 04 is connected to each second signal input terminal of the outdoor control board 05. For example, Y1 of the indoor control board 04 is connected to Y1OUT of the outdoor control board 05, Y2 of the indoor control board 04 is connected to Y2OUT of the outdoor control board 05, O of the indoor control board 04 is connected to O of the outdoor control board 05, and W1 of the indoor control board 04 is connected to W of the outdoor control board 05.

[0123] It should be noted that if the control unit 02 includes: an indoor control board 04 and an outdoor control board 05, the control system is an air-conditioning control system.

[0124] The above is only a specific implementation of the control unit 02. In practical applications, including but not limited to this, no specific limitation is made here. It can be determined according to the specific situation and is within the scope of protection of this application.

[0125] Another embodiment of the present application provides another specific implementation of the control unit 02. This implementation differs from the above implementation in that:

[0126] In this embodiment, if Figure 18 As shown, the power supply interface of the indoor control board 04 and the power supply interface of the outdoor control board 05 both have a grounded common terminal C and a power supply terminal R connected to the AC power. The power supply terminal R of the power supply interface of the outdoor control board 05 is connected to the power supply terminal R of the power supply interface of the indoor control board 04. The common terminal C of the power supply interface of the outdoor control board 05 is connected to the common terminal C of the power supply interface of the indoor control board 04.

[0127] Typically, if Figure 18 As shown, the power supply terminal R of the power supply interface of the indoor control board 04 is connected to one end of the secondary winding of the transformer 03 to receive AC power; the common terminal C of the power supply interface of the indoor control board 04 is connected to one end of the secondary winding of the transformer 03 to be grounded.

[0128] In this embodiment, since the indoor control board 04 and the outdoor control board 05 draw power from the same location, the connection relationship between the various components in the control system can be simplified, thereby reducing the connection difficulty of the control system and thus reducing the overall cost of the control system.

[0129] Another embodiment of the present application provides a control device, the specific structure of which is as follows: Figure 19 As shown in 100 , it specifically includes: an air conditioner control unit 02 and a wiring prompt circuit 06 .

[0130] The wiring prompt circuit 06 includes at least one prompt device 10 and at least one rectifier branch 20. The connection relationship between the wiring prompt circuit 06, the wired controller 01, and the air conditioner control unit 02 is as follows:

[0131] Each prompting device 10 is connected in series with a rectifier branch 20. The first end of the series branch is connected to a signal output terminal of the wire controller 01 to receive signal instructions. The second end of the series branch is connected to the power supply terminal R or the common terminal C of the power supply interface of the wire controller 01. The potential change of the signal instruction is the same as the power supply terminal R of the power supply interface of the wire controller 01. The power supply terminal R of the power supply interface of the wire controller 01 is connected to AC power, and the common terminal C of the power supply interface of the wire controller 01 is grounded.

[0132] Each prompting device 10 can issue a prompt when it is powered.

[0133] If the number of prompting devices 10 and the number of rectifying branches 20 are greater than 1, the second ends of the series branches formed by the prompting devices 10 and the rectifying branches 20 are connected to the same end of the power supply interface of the wired controller 01 .

[0134] It should be noted that the series branches formed by the prompting devices 10 and the rectifying branches 20 have been described in detail in the above embodiments and will not be repeated here.

[0135] Each signal input terminal of the control unit 02 is connected to each signal output terminal of the wire controller 01 in a one-to-one correspondence. Figure 19 As shown, the signal output terminal G of the wire controller 01 is connected to the signal input terminal G of the control unit 02, the signal output terminal Y1 of the wire controller 01 is connected to the signal input terminal Y of the control unit 02, the signal output terminal O of the wire controller 01 is connected to the signal input terminal O of the control unit 02, the signal output terminal W1 of the wire controller 01 is connected to the signal input terminal W1 of the control unit 02, and the signal output terminal W2 of the wire controller 01 is connected to the signal input terminal W2 of the control unit 02.

[0136] In this embodiment, since one end of each series branch in the wiring prompt circuit 06 is connected to a signal output end of the wired controller 01, the control device can also prompt the assembler whether the two poles of the power supply interface of these wired controllers 01 are reversed.
