[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be understood as limiting the present application.

[0025] See also Figure 1 and Figure 2The present application provides an air conditioning device 1000. The air conditioning device 1000 includes a main control module 100 and an energy metering module 200. The main control module 100 is in communication with the energy metering module 200. The energy metering module 200 is configured to detect multiple energy parameters of the air conditioning device 1000 in real time. When at least one energy parameter exceeds a corresponding energy protection range, the module generates abnormal energy information and transmits it to the main control module 100. The main control module 100 is further configured to adjust the operating state of the air conditioning device 1000 based on the abnormal energy information.

[0026] It can be understood that since the present application integrates the electric energy metering module 200 into the interior of the air-conditioning equipment 1000, the requirements for the installation location, waterproof and dustproof protection level, etc. are relatively low, which can reduce the overall installation cost of the air-conditioning equipment 1000.

[0027] Specifically, the energy metering module 200 may be an electric meter for detecting electric energy information such as current, voltage, and power in the air conditioner 1000. The energy metering module 200 can measure the power consumption of the air conditioner 1000 with an accuracy of less than 1%, which is a high power measurement accuracy.

[0028] The electric energy parameters may include voltage parameters, current parameters, power parameters, and electric quantity parameters. Correspondingly, the electric energy protection range may include a voltage protection range, a current protection range, a power protection range, and an electric quantity protection range. That is, when the electric quantity metering module 200 detects that the values of one or more parameters among the voltage, current, power, and electric quantity of the main control device 100 are too low or too high, it can be considered that the current operating state of the air-conditioning device 1000 is abnormal. In detail, the voltage protection range can be determined by a first voltage protection threshold and a second voltage protection threshold, and the first voltage protection threshold is greater than the second voltage protection threshold. The current protection range can be determined by a first current protection threshold and a second current protection threshold, and the first current protection threshold is greater than the second current protection threshold.

[0029] The power protection range may be determined by a first power protection threshold and a second power protection threshold, wherein the first power protection threshold is greater than the second power protection threshold. The power protection range may be determined by a first power protection threshold and a second power protection threshold, wherein the first power protection threshold is greater than the second power protection threshold.

[0030] Abnormal electric energy information may include: (1) abnormal current information when the voltage is greater than or equal to the first voltage protection threshold, or abnormal current information when the voltage is less than or equal to the second voltage protection threshold; (2) abnormal current information when the current is greater than or equal to the first current protection threshold, or abnormal current information when the current is less than or equal to the second current protection threshold; (3) abnormal power information when the power is greater than or equal to the first power protection threshold, or abnormal power information when the power is less than or equal to the second power protection threshold; (4) abnormal power information when the power is greater than or equal to the first power protection threshold, or abnormal power information when the power is less than or equal to the second power protection threshold.

[0031] The main control module 100 can adjust the operating state of the air-conditioning device 1000 in time according to the abnormal power information detected by the power metering module 200 to protect the air-conditioning device 100 and improve the operating reliability of the air-conditioning device 1000.

[0032] Therefore, the electric energy metering module 200 of the present application can not only transmit electric quantity information to the main control module 100, but also transmit abnormal information such as power information, current information and voltage information in addition to electric quantity information to the main control module 100, thereby increasing the amount of information transmitted.

[0033] In this way, the air conditioning device 1000 of the present application can integrate the power metering module 200 into the air conditioning device 1000, thereby reducing the overall installation cost of the air conditioning device 1000. In addition, the power metering module 200 can transmit various abnormal power information such as power information, current information, and voltage information in addition to power information to the main control module 100, thereby increasing the amount of information transmitted. The main control module 100 can also adjust the operating status of the air conditioning device 1000 in a timely manner based on the abnormal power information detected by the power metering module 200 to protect the air conditioning device 100, thereby improving the operational reliability of the air conditioning device 1000.

[0034] In some embodiments, at least one electric energy protection range is pre-set in the main control module 100 , and the main control module 100 is further configured to send the electric energy protection range to the electric energy metering module 200 .

[0035] That is, the power protection range of the present application can be pre-set and pre-stored in the main control module 100. When the air conditioner 1000 is powered on and initialized, the main control module 100 can actively send at least one power protection range to the power metering module 200, such as Figure 2 shown.

[0036] Specifically, the transmission data type of the relevant power protection threshold corresponding to the power protection range transmitted by the main control module 100 to the power metering module 200 is as follows: Figure 3As shown. The voltage protection thresholds sent by the main control module 100 may include the effective value of the phase voltage, the voltage drop instantaneous protection threshold, and the overvoltage protection threshold. The current protection thresholds sent by the main control module 100 may include the effective value of the phase current, the current drop instantaneous protection threshold, and the overcurrent protection threshold. The power protection thresholds sent by the main control module 100 may include thresholds for active power, reactive power, apparent power, and power factor. The power protection thresholds sent by the main control module 100 may include thresholds for forward active energy metering and forward reactive energy metering.

[0037] In some embodiments, when multiple power protection ranges are pre-set in the main control module 100, the power protection ranges are set in a one-to-one correspondence with the power parameters.

[0038] That is, as mentioned above, when there are multiple electric energy protection ranges in the present application, the electric energy protection ranges are set in one-to-one correspondence with the electric energy parameters, so that the electric energy metering module 200 can detect whether there are abnormalities in different electric energy parameters according to different electric energy protection ranges, and thus send abnormal electric energy information to the main control module 100 in time, so that the main control module 100 can adjust the operating status of the air-conditioning equipment 1000 in time according to the abnormal electric energy information to protect the air-conditioning equipment 100 and improve the operating reliability of the air-conditioning equipment 1000.

[0039] In some embodiments, the communication connection mode between the main control module 100 and the electric energy metering module 200 includes a MODBUS communication mode.

[0040] Specifically, the MODBUS communication method has the following advantages: (1) strong versatility, which can achieve cross-industry and cross-device compatibility; (2) high efficiency and simplicity, which can reduce communication overhead and improve real-time performance.

[0041] That is, the electric energy metering module 200 and the main control module 100 of the present application can adopt the MODBUS communication method to replace the original DL / T 645-2007 communication method between the external meter and the air-conditioning equipment 1000, and can transmit multiple electric energy information such as voltage, current, power, and electric energy, while greatly improving the communication speed between the two.

[0042] In other embodiments of the present application, the communication connection mode between the main control module 100 and the electric energy metering module 200 can also be other modes, which are not limited here.

[0043] In some embodiments, the abnormal power information includes abnormal power parameters. The operating state of the air conditioner 1000 includes shutdown and limited operating frequency. The main control module 100 is further configured to adjust the operating state of the air conditioner 200 to shutdown or limited operating frequency below a preset frequency threshold based on the abnormal power parameters.

[0044] Specifically, the abnormal electric energy parameters may include the abnormal voltage parameters, abnormal current parameters, abnormal power parameters and abnormal electric quantity parameters mentioned above.

[0045] That is, the main control module 100 of the present application can adjust the operating state of the air-conditioning equipment 200 to shutdown or limit the frequency to below the preset frequency threshold through any one parameter value or multiple parameter values of the abnormal voltage parameter, abnormal current parameter, abnormal power parameter and abnormal power parameter in the abnormal power information.

[0046] For example, when at a certain moment, the electric energy metering module 200 detects that the voltage parameter of the air-conditioning equipment 1000 is lower than the second voltage protection threshold, the voltage parameter can be recorded as an abnormal voltage parameter, and the abnormal electric energy information with the abnormal voltage parameter can be sent to the main control module 100. The main control module 100 determines that the current air-conditioning equipment 1000 is in an operating state with too low voltage based on the abnormal electric energy information, and can adjust the operating state of the air-conditioning equipment 1000 to shutdown, or limit the operating frequency of the air-conditioning equipment 1000 to be lower than the preset frequency threshold.

[0047] Whether the main control module 100 adjusts the operating state of the air conditioner 1000 to shutdown or to limit the operating frequency to below a preset frequency threshold can be set based on the specific value of the voltage parameter. Understandably, in this case, the voltage parameter value corresponding to adjusting the operating state of the air conditioner 1000 to shutdown will be smaller than the voltage parameter value corresponding to adjusting the operating state of the air conditioner 1000 to limit the operating frequency to below a preset frequency threshold.

[0048] That is to say, when the abnormality level of the power parameters of the air-conditioning equipment 1000 is high, the main control module 100 can adjust the operating state of the air-conditioning equipment 1000 to limit the operating frequency to be lower than the preset frequency threshold. When the abnormality level of the power parameters of the air-conditioning equipment 1000 is the highest, the main control module 100 can adjust the operating state of the air-conditioning equipment 1000 to shutdown.

[0049] In some embodiments, the abnormal power information includes the time when the abnormality occurs, and the main control module 100 is further used to adjust the operating state of the air-conditioning equipment 1000 according to the time when the abnormality occurs to limit the operating frequency to be lower than a preset frequency threshold during a preset operating time period.

[0050] For example, if the energy metering module 200 detects that the voltage of the air conditioner 1000 frequently exceeds the first voltage protection threshold between 2:00 PM and 4:00 PM, the main control module 100 can proactively limit the operating frequency to below the preset frequency threshold during this period to prevent malfunction of the air conditioner 1000. The time point at which the abnormality occurs between 2:00 PM and 4:00 PM is the abnormality occurrence time, and the preset operating time period is the time range between 2:00 PM and 4:00 PM.

[0051] In this way, the electric energy metering module 200 of the present application can also send the time point with the time when the abnormality occurs to the main control module 100, so that the main control module 100 adjusts the operating status of the air-conditioning equipment 1000 according to the time when the abnormality occurs to limit the operating frequency to below the preset frequency threshold during the preset operating time period, thereby preventing the air-conditioning equipment 1000 from malfunctioning.

[0052] In some embodiments, the abnormal power information includes the duration of the abnormality. The main control module 100 is also used to determine that the power abnormality of the air-conditioning equipment 1000 is serious when the duration of the abnormality is greater than or equal to the preset duration, and adjust the operating state of the air-conditioning equipment 1000 to shutdown.

[0053] Specifically, the preset duration may be, for example, 10S, 11S, 12S, 13S, 14S, 15S, 16S, 17S, 18S or 19S, which is not limited here.

[0054] That is, the electric energy metering module 200 of the present application can also send abnormal electric energy information with the duration of the abnormality to the main control module 100, so that the main control module 100 adjusts the operating status of the air-conditioning equipment 1000 according to the duration of the abnormality.

[0055] In this way, the main control module 100 of the present application can determine that the power anomaly of the air-conditioning equipment 1000 is serious when the anomaly lasts longer than or equal to the preset time, adjust the operating state of the air-conditioning equipment 1000 to shutdown, and stop the loss in time.

[0056] In some embodiments, the main control module 100 is further configured to send abnormal power information to the cloud, so that the cloud generates an abnormal power prompt based on the abnormal power information.

[0057] Specifically, the cloud platform can be, for example, a cloud platform. If the abnormal power information is "current continuously exceeding the limit," the cloud platform can, upon receiving this abnormal power information, push a text message to the user's mobile terminal stating, "The air conditioner current is abnormal. Contact maintenance is recommended." Upon receiving this abnormal power information, operations and maintenance personnel can also directly issue control instructions, such as frequency limiting and forced shutdown, through the cloud platform, facilitating troubleshooting and reducing on-site troubleshooting costs.

[0058] That is, the main control module 100 of the present application can also actively transmit abnormal power information to the cloud, so that the cloud generates abnormal power prompts based on the abnormal power information, which facilitates operation and maintenance personnel to conduct fault troubleshooting and reduces on-site troubleshooting costs.

[0059] In some embodiments, the main control module 100 is further configured to send abnormal power information to a user's mobile terminal, so that the user's mobile terminal generates an abnormal power prompt according to the abnormal power information.

[0060] Specifically, the abnormal power prompt can be, for example, "Abnormal voltage detected (190V), the air conditioner has automatically switched to energy-saving mode, it is recommended to check the power grid", "Standby power consumption is abnormal (50W>normal 5W), it is recommended to turn off the physical switch" and other text prompts or voice prompts. The method of abnormal power prompt is not limited here.

[0061] For example, the main control module 100 can send abnormal power information to the application of the corresponding air-conditioning equipment 1000 on the user's mobile terminal, so that the user can be informed of air-conditioning abnormalities in the first time, such as a sudden voltage drop causing the compressor to shut down for protection, to avoid the sudden failure of the air-conditioning equipment 1000 affecting comfort.

[0062] In this way, the main control module 100 of the present application is also used to send abnormal power information to the user's mobile terminal, so that the user's mobile terminal generates an abnormal power prompt based on the abnormal power information, so that the user can be informed of the air-conditioning abnormality in the first time, such as a sudden voltage drop causing the compressor to shut down for protection, to avoid the sudden failure of the air-conditioning equipment 1000 affecting comfort.

[0063] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
