Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner control, in particular to a communication control system and method based on air conditioner. BACKGROUND

[0002] Traditional air conditioner control systems often rely on complex wiring layouts, including two dedicated communication lines for transmitting control instructions and two power supply lines to ensure power supply to the equipment. This design not only increases material costs, but also makes the installation and maintenance process cumbersome and time-consuming. However, with the advancement of technology, the introduction of POWERBUS technology has completely revolutionized this situation. POWERBUS ingeniously uses power line carrier communication (PLC) technology, which can simultaneously complete power supply and control signal transmission with only two power supply lines, greatly simplifying the wiring structure of the air conditioner system, effectively reducing the production and installation costs of the air conditioner, and improving the overall energy efficiency ratio, providing a more economical and environmentally friendly solution for users.

[0003] However, it is worth noting that this innovative solution also faces challenges in specific application scenarios. Specifically, when the air conditioner outdoor unit needs to connect and manage multiple air conditioner indoor units simultaneously, the communication efficiency and stability of the POWERBUS technology may be affected. Since multiple indoor units share the same power supply line for communication, signal interference or conflicts may occur, leading to communication abnormalities. In the long run, such unstable communication not only affects the operating efficiency of the air conditioner system and user experience, but also may cause irreversible damage to the communication chip, increasing the cost and difficulty of later maintenance.

In the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in specific circumstances.

[0046] As shown in Figs. 1-2 An air conditioner-based communication control system includes an outdoor unit, an indoor unit, a communication master station, a communication slave station, a signal receiving module, and a signal processing module.

[0047] Each indoor unit is provided with a communication slave station and a signal receiving module.

[0048] The signal receiving module is configured to receive a user's adjustment signal and send the adjustment signal to the signal processing module.

[0049] The signal processing module is configured to analyze the adjustment signal, determine whether the number of adjustment signals is equal to the number of indoor units, if not, obtain the communication address of the indoor unit, and attach the communication address to the adjustment signal to obtain a processing signal, and send the processing signal to the communication slave station of the corresponding indoor unit.

[0050] If equal, determine whether the instructions of all adjustment signals are consistent, if consistent, generate a common signal, combine the common signal and the adjustment signal into a processing signal, and send the processing signal to any communication slave station.

[0051] If not consistent, obtain the communication address of the indoor unit, and attach the communication address to the adjustment signal to obtain a processing signal, and send the processing signal to the communication slave station of the corresponding indoor unit.

[0052] The communication slave station is configured to send the processing signal to the communication master station.

[0053] The communication master station is used for receiving the processing signal, if the number of the processing signal at the current time is greater than 2, the processing signal is parsed according to the received order, the control instruction and the communication address are generated, and the control instruction and the communication address are sent to the external machine;

[0054] If the number of the adjustment signal at the current time is not greater than 2, the processing signal is parsed, it is judged whether the parsed instruction contains a common signal, if there is, only the control instruction is sent to the external machine, if not, the control instruction and the communication address are generated and sent to the external machine;

[0055] The external machine is used for judging whether the received content contains the communication address, if there is, the corresponding internal machine control area is found according to the communication address, and the control instruction is executed, if not, the control instruction is executed on the control area of all internal machines.

[0056] In order to solve the problem of signal, in the present application, a signal processing module is arranged, when the user issues an adjustment signal, the adjustment signal is sent to the signal processing module, the signal processing module first judges whether the number of the adjustment signal is equal to the number of the internal machine, when the number of the adjustment signal is not equal to the number of the internal machine, it indicates that the current adjustment signal is not for all internal machines. In order to facilitate finding the corresponding internal machine, the communication address of the internal machine is added in the adjustment signal to obtain the processing signal. When the external machine parses, the corresponding control area can be found according to the communication address, and the corresponding control adjustment is carried out. When the number of the adjustment signal is equal to the number of the internal machine, it is possible that all internal machines are uniformly processed, for example, uniformly reducing the temperature X degrees. Therefore, it is also necessary to judge whether the instructions of the adjustment signal are consistent, when the instructions of the adjustment signal are consistent, a common signal is generated. It is worth mentioning that at this time, since all internal machines are adjusted, it is not necessary to attach the corresponding communication address, at this time, the transmission content of the signal can be reduced. In order to facilitate the transmission of the signal by using the POWERBUS communication unit. If not, the internal machine communication address is obtained, and the communication address is attached to the adjustment signal to obtain the processing signal, and the processing signal is sent to the corresponding internal machine communication slave station. The corresponding control area is found through the communication address.

[0057] The signal processing module can intelligently judge the number and consistency of the received adjustment signal, so as to decide how to generate and process these signals. When the adjustment signals of all internal machines are consistent, a common signal is generated and sent, the data transmission amount is reduced, and the efficiency is improved. When the signals are inconsistent, they are processed respectively, and the independent control of each internal machine is ensured.

[0058] The communication master station is arranged in the outdoor unit, when the communication slave station sends a processing signal, the communication master station will accept all the processing signals and analyze, and the communication master station is analyzed in the order of acceptance. The analyzed instruction can be sent to the outdoor unit by the communication master station in sequence, and the sequence is executed, which will not cause the control signal to conflict in execution. Finally, the signal transmission problem of multiple indoor units and a single outdoor unit of the air conditioner is solved.

[0063] In another embodiment of the application, a marking module is provided, which marks the type of adjustment signal, because in the control of the air conditioner, there is control related to the indoor unit, such as change of air direction, air purification control, etc., at this time, the adjustment signal does not involve the adjustment of the outdoor unit, so the communication master station and the communication slave station are not needed, and the adjustment signal is marked as the first signal, when the classification unit of the signal receiving module identifies the first mark, the first signal will not be sent to the signal processing module, so as to reduce the data processing amount of the signal processing module, optimize the flexibility and efficiency of signal processing. At the same time, the complexity of the air conditioning system in the control of multiple indoor units is reduced. When the system fails or needs to be maintained, the problem can be located more easily, and corresponding measures can be taken for repair. This maintainability reduces the maintenance cost of the system and improves the reliability and stability of the system.
