The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator in the present application. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the ambient environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
As shown in fig. 1, an outdoor unit includes:
an outdoor unit comprising:
a gateway fixed in a casing of the outdoor unit;
the cloud platform is connected with the gateway through a wireless communication module;
the gateway is used for periodically sending heartbeat packets to the cloud platform; the information of the heartbeat packet comprises whether the outdoor unit is in a transportation mode and a real-time cell number cellID;
the cloud platform is used for storing a plurality of historical cell numbers cellID and corresponding position information; and the system is further used for comparing the real-time cell number cellID with the historical cell number cellID and outputting the position information of the real-time cell number cellID according to the comparison result. The method can effectively avoid the problem that the position is still inquired when the actual position of the gateway is not changed (such as in storage for a long time), and the corresponding cost is generated.
In some embodiments of the present invention, the gateway employs an NB-IoT communication module, and the historical cell number cellID or the real-time cell number cellID represents the number ID of the NB-IoT signal coverage area in the current state.
In some embodiments of the present invention, it is specifically determined whether the outdoor unit is in the transportation mode according to a power supply manner of the gateway; when the gateway is powered by a battery, the gateway judges that the outdoor unit is in a transportation mode; when the gateway is powered by the outdoor unit, the gateway judges that the outdoor unit is in a working mode. In the working mode, the gateway is in the installation completion state, the position of the gateway is not changed any more, and the position track is not required to be drawn.
In some embodiments of the present invention, in the transportation mode, the process of the gateway obtaining the location information from the operator is: when the gateway sends the heartbeat packet, sending the real-time cell number cellID to the cloud platform, sending a command for inquiring position information to the background of an operator by the cloud platform, and then receiving the position information of the real-time cell number cellID sent by the operator platform, namely obtaining the position information of the heartbeat packet sending time. The cloud platform stores the position of the heartbeat time. After the heartbeat packet is continuously sent for multiple times, the cloud platform draws the position track of the gateway according to the position information.
In some embodiments of the present invention, when the cloud platform draws a certain gateway transportation track, only the first point of the same location different from the previous location in the record is reserved, that is, when the positions of adjacent points change, only the first point is saved, but the track drawing is not performed. Usually, when the location is not generated, the real-time cell numbers cellids reported by the gateways may still be different (i.e., the same location may correspond to multiple cellids, usually 3 to 4 or less). As long as the position changes, the CellID in the report of the heartbeat package must change.
In some embodiments of the present invention, as shown in fig. 2, after the initial heartbeat packet is sent, according to the frequency of sending the heartbeat packet, the cloud platform stores the cell number cellID and queries the corresponding location information for 3 consecutive times, that is, stores the cell number cellID and the corresponding location information as the historical cell number cellID; after the 3 rd time, along with the real-time cell number cellID sent by the heartbeat packet, the cloud platform compares the real-time cell number cellID with the previously stored three-time historical cell number cellID, if the real-time cell number cellID is consistent with one of the previous three-time historical cell number cellIDs, position information cannot be inquired from the background of the operator, the position information corresponding to the same historical cell number cellID is output (namely, stored and displayed), and meanwhile, the next time of sending the heartbeat packet of the gateway is continuously waited. And if the comparison real-time cell number cellID of the cloud platform is different from the last three historical cell numbers cellID, inquiring the position information of the real-time cell number cellID from the operator platform, simultaneously storing and displaying, and sequentially performing cyclic judgment.
In some embodiments of the present invention, the historical cell number cellID and the corresponding location information stored in the cloud platform are not limited to the previous 3 heartbeat packets of the heartbeat packet including the real-time cell number cellID, and may also be the cell number cellID corresponding to the previous 4 or 5 heartbeat packets. Therefore, the effective position track of the gateway in the transportation process can be recorded, and the cost of position information inquiry is reduced.
In some embodiments of the present invention, as shown in fig. 3, the cloud platform is further configured to establish a time-efficient database, where the database includes a corresponding relationship between a cell number cellID and location information. Specifically, as the number of gateways accessing the cloud platform increases, the cloud platform may collect more correspondence between the cell number cellID and the actual location information. However, the corresponding relationship does not continue, so the cloud platform sets the validity period of each corresponding relationship in the database. And in the validity period, storing the corresponding relation, and clearing the corresponding relation information outside the validity period, namely the cloud platform is used for deleting the corresponding relation between the cell number cellID which is positioned outside the validity period and the position information in the database.
In some embodiments of the invention, the database has an age of no less than 6 months. If the expiration date is 6 months, the first storage life is started according to each group of corresponding relations, and after 6 months, the corresponding relations of the groups are cleared. And sequentially and iteratively storing the corresponding relation between the cell number cellID and the position information.
In some embodiments of the present invention, according to heartbeat packet information sent by a gateway, a cloud platform queries a database of correspondence between a stored cell number cellID and location information, and if the database has a cell number cellID that is consistent with a real-time cell number cellID, the cloud platform takes the location information stored in the database as the latest location of the gateway; if the real-time cell number cellID is not consistent with the cell number cellID in the database, the cloud platform queries corresponding position information from an operator background according to established logic to serve as the latest positioning of the intelligent gateway; and simultaneously storing the latest received corresponding relation between the real-time cell number cellID and the position information into a database, and marking the validity period of the corresponding relation. Namely, the cloud platform is further configured to store the corresponding relationship between the real-time cell number cellID and the location information thereof to update the database.
In some embodiments of the invention, the refined position track drawing is realized by increasing the frequency of heartbeat packets sent by the gateway. Specifically, the gateway may be required to cache the last cell number cellID, and if the cell number cellID changes (is different from the last cell number cellID) and is already stable (for example, the cell number cellID remains unchanged within 30 min), the gateway reports the cell number cellID, and the cloud platform outputs the location information according to the above contents.
Compared with the prior art, the technical scheme of the invention has the following technical effects:
according to the invention, the historical cell number cellID is stored in the cloud platform, the real-time cell number cellID in each heartbeat packet is compared with the historical cell number cellID, and when the cellIDs of the real-time cell number cellID and the historical cell number cellID are consistent, the cloud platform can directly output the position information corresponding to the historical cell number cellID as the position information of the real-time cell number cellID, so that repeated inquiry is avoided, the inquiry cost is saved, and the track of the outdoor unit is effectively recorded.
In addition, the database is established on the cloud platform, the corresponding relations between the cell numbers cellID and the position information of the cell numbers cellID are stored in the database, and the time validity period is set for each corresponding relation, so that the accuracy of the position information of the outdoor unit can be effectively improved. The cloud platform compares the real-time cell number cellID in the received heartbeat packet with the cell number cellID in the database, and if the cell number cellID consistent with the real-time cell number cellID is in the database, the cloud platform directly obtains position information of the cloud platform according to the corresponding relation and outputs the position information, so that the frequency of inquiring the background of an operator by the cloud platform is reduced to a greater extent. In addition, for the real-time cell number cellID which is not in the database, the cloud platform stores the corresponding relation into the database after inquiring, and supplements the database; in addition, the data of the updated database are deleted in time according to the time limit of each corresponding relation, so that the position query accuracy is improved, and the query times of the cloud platform are reduced.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
