In some embodiments of the present disclosure, for example, as shown in FIG. 1, the data transmission system 10 may further include a service side 103, the first server 101 transmitting data from the service side 103 to the second server. Get the data of

For example, after the installation of the air conditioning system 100 is completed, the service side 103 provides capacity information, such as horsepower information, of each outdoor unit and each indoor unit in the air conditioning system 100, and, for example, the room in which each indoor unit is installed. Location information for each outdoor unit and each indoor unit, such as orientation information and/or geographic location information for each outdoor unit and each indoor unit is recorded.

The service side 103 stores the above information, and the first server 101 can acquire the above information from the service side 103 as necessary.

When the first server 101 acquires the second data of the air conditioning system 100, for example, the second server 102 acquires the second data of the air conditioning system 100 from the first server 101 and , the energy consumption data of the air conditioning system 100 and the second data of the air conditioning system 100 are calculated.

In some embodiments of the present disclosure, the energy consumption data identified by the second server 102 may include power consumption data for the outdoor units of the air conditioning system 100 .

For example, when the air conditioning system 100 includes multiple refrigerant systems, includes multiple sets of outdoor units, and the multiple refrigerant systems (multiple sets of outdoor units) are connected to the same smart power meter, the second server The energy consumption data identified by 102 may be data on the total power consumption of a plurality of sets of outdoor units.

When the air conditioning system 100 includes multiple refrigerant systems, includes multiple sets of outdoor units, and each of the multiple refrigerant systems (multiple sets of outdoor units) is connected to one smart power meter, the second server 102 The energy consumption data identified by may be data on the amount of electric power for each set of outdoor units.

Also, if the air conditioning system 100 includes a refrigerant system, includes a set of outdoor units, and the set of outdoor units is connected to a smart power meter, the energy consumption determined by the second server 102 may be data on the amount of electric power of the outdoor unit of the set.

In some embodiments of the present disclosure, the second server 102 may process power consumption data to form energy consumption data when the user side 300 initiates a request. The second server 102 may also autonomously process the energy consumption data according to a fixed time period or rule to form energy consumption data, and the obtained energy consumption data is 2 server 102 .

Thereby, when the user side 300 needs to obtain the energy consumption data of the air conditioning system, it can directly obtain it from the second server 102, further shortening the time for the user side 300 to obtain the energy consumption data. do. Further improved the speed and efficiency with which users obtain energy consumption data, further enhancing the user experience.

Hereinafter, an example will be described in which the first data includes the operating time and/or indoor temperature of the air conditioning system 100, and the second data includes capacity data of the outdoor unit.

In some embodiments of the present disclosure, when multiple sets of outdoor units are connected to one smart power meter, for example, the total capacity of all outdoor units, the capacity of each set of outdoor units and the smart power meter The power energy data of each set of outdoor units can be calculated based on the power energy data. Or, based on the total capacity of all outdoor units, the capacity of each set of outdoor units, the operating time of each set of outdoor units, and the power consumption data on the smart power meter, the power consumption data of each set of outdoor units can also be calculated. In this way, the non-operating time after the indoor temperature of the outdoor unit reaches the set value is taken into account when starting, and the calculation result is made more accurate.

In some embodiments of the present disclosure, when a set of outdoor units are connected to one smart power meter, the power energy data on the smart power meter is the power data of the set of outdoor units. be.

Thereby, the energy consumption data of the air conditioning system is specified based on all of the first data of the air conditioning system, the second data of the air conditioning system, and the data of the power consumption of the air conditioning system. In this case, the energy consumption data of the air conditioning system can be calculated more accurately.

In some embodiments of the present disclosure, the energy consumption data may further include the allocated power amount of each indoor unit connected to the set of outdoor units.

For example, the second server 102 acquires the second data of the air conditioning system 100 from the first server 101, the first data of the air conditioning system 100, the power amount data of the air conditioning system 100, and the power consumption data of the air conditioning system 100. Based on the second data, the allocated power amount for each indoor unit is calculated.

For example, based on the total capacity of indoor units connected to one refrigerant system, the capacity of each indoor unit, and the operation time of each indoor unit, the amount of electric power allocated to each indoor unit is calculated. Called).

　Preferably, the first calculation method can be further corrected based on the environmental data of the air conditioning system. For example, the allocated power amount is optimized based on environmental data such as room temperature and set temperature. For example, when an air conditioner performs cooling, the initial temperature of the room where the indoor unit A is located is high and the set temperature is low, but the initial temperature of the room where the indoor unit B is located is low and the set temperature is high. , with respect to indoor unit B, indoor unit A should have a higher allocated power amount.

Therefore, in the process of calculating the power allocation for each indoor unit connected to a set of outdoor units according to method 1, the power allocation for indoor unit A and indoor unit B can be corrected according to the rule above (method called two).

Preferably, the allocated power amount can be further corrected based on both the environmental data of the air conditioning system and the second data.

For example, based on the location information of the air conditioning system, such as information such as geographical location and direction of the room where the indoor unit is located, and the environmental information of the outdoor where the air conditioning system is located, such as weather information and sunshine conditions, different The outdoor load of the room in which the indoor unit is located is obtained, and the electric energy allocated to the indoor unit is corrected based on the outdoor load.

For example, when an air conditioner cools, an indoor unit C installed in a room with long sunshine hours should have a higher allocated power amount than an indoor unit D installed in a room with short sunshine hours. In the process of calculating the allocated power amount, the allocated power amount of the indoor unit C and the indoor unit D can be corrected according to the above rule.

Thereby, the allocated power amount is specified and corrected based on all of the first data of the air conditioning system, the second data of the air conditioning system, and the data of the power amount of the air conditioning system. In this case, the energy consumption data of each device in the air conditioning system can be calculated more accurately and precisely.

In addition, it is possible to comprehensively consider the operation data of the air conditioning system and the environmental data of the air conditioning system when calculating the allocated power amount, thereby improving the accuracy of the calculation of the allocated power amount.
