The outdoor unit master control equipment is used for storing slave control addresses of all the connected outdoor unit slave equipment, controlling the connected indoor units through an HBS (high bandwidth bus) protocol according to the control instructions when the control instructions needing broadcasting are received, and sending the control instructions to all the connected outdoor unit slave equipment through the HBS protocol; when a control instruction which does not need broadcasting is received, whether the connected indoor unit is a target indoor unit corresponding to the control instruction is determined, if yes, the connected indoor unit is controlled through an HBS bus protocol according to the control instruction, and feedback information from the indoor unit is sent to the centralized controller through an RS485 communication module, so that the centralized controller is sent to the service management control platform 501 through the network communication module 502, otherwise, a target slave device address of a target outdoor unit slave device connected with the target indoor unit is determined from the stored slave control addresses, and the control instruction is sent to the target outdoor unit slave device through the HBS bus protocol and the target slave device address.
Specifically, each outdoor unit slave device has its own slave control address, such as a Homebus address, and when receiving a control instruction to be broadcasted, the outdoor unit master control device may control its connected indoor unit according to the control instruction, and issue the control instruction to each connected outdoor unit slave device through the slave control address of each connected outdoor unit slave device, so that the outdoor unit slave device controls the connected indoor unit to complete the operation corresponding to the control instruction. When the outdoor unit main control device receives a control instruction which does not need broadcasting, whether the outdoor unit main control device is a target outdoor unit corresponding to the control instruction or not needs to be determined, if yes, a connected target indoor unit can be controlled according to the control instruction, otherwise, a target slave device address of a target outdoor unit slave device connected with the target indoor unit can be determined, and the control instruction is issued to the target outdoor unit slave device through the target slave device address so that the target indoor unit can be controlled.
The outdoor unit main control equipment reports feedback information from connected indoor units to the centralized controller, so that the centralized controller reports the feedback information to the service management control platform, and the working state of the indoor unit is visually displayed through the service management control platform.
The outdoor unit main control equipment and the indoor units connected with the outdoor unit main control equipment, the outdoor unit main control equipment and the outdoor unit slave equipment, and the outdoor unit slave equipment and the indoor units connected with the outdoor unit slave equipment are interacted by utilizing a Homebus mechanism through an HBS bus protocol, so that the outdoor unit, the outdoor unit and the indoor units are in remote communication, and centralized management of the central air conditioner is realized.
The outdoor unit master control equipment and at least one indoor unit slave equipment connected with the outdoor unit master control equipment can form a refrigerant subsystem, so that the centralized manager can conveniently issue information by determining the outdoor unit master control equipment in the refrigerant subsystem corresponding to the instruction after receiving the instruction, and the outdoor unit slave equipment in the refrigerant system can be managed by the outdoor unit master control equipment.
