Detailed Description
The idea and purpose of the method for controlling the air conditioner indoor unit by the wire controller provided by the embodiment of the invention are as follows:
in the prior art, if air conditioner internal units with dial switches are arranged in a group, when the dial switch bits are used up, if a new function needs to be added, a new dial switch needs to be added on each air conditioner internal unit to set functional attributes, or when a new air conditioner internal unit needs to be added, a dial switch needs to be added for each air conditioner internal unit to expand address bits; in the invention, the wire controller controls a group of air conditioner internal machines, namely, the air conditioner internal machine with a dial address and the air conditioner internal machine without the dial address are provided, the air conditioner internal machine without the dial address removes dial switches used for setting addresses and functions of partial air conditioner internal machines, and only one-bit dial switch is reserved for setting the attributes of a host machine or a slave machine; the air conditioner internal machine with the dial switch is set as a slave machine, when the on-line controller controls the air conditioner internal machine, the control instruction is sent to the host machine, at the moment, other air conditioner internal machines in the set can monitor the control instruction sent by the line controller from a communication line and judge whether the control instruction is sent to the on-line controller, and if the control instruction is sent to the on-line controller, the on-line controller executes the control instruction and returns information to the line controller. The control mode can get rid of the limitation of the dial switch on the communication protocol code, namely, the code set by the dial switch is removed in the communication protocol of the air conditioner indoor unit controlled by the line controller; when a new function needs to be added or a new air conditioner indoor unit needs to be added to the indoor unit of the air conditioner in the group, the limitation of the dial switch position is not limited, the dial switch does not need to be added to the indoor unit of the air conditioner in the group, only a communication protocol needs to be changed, the control difficulty of the wire controller is reduced, and the design, the management and the maintenance are simplified.
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, a flowchart of a method for controlling an air conditioner internal unit by a line controller according to an embodiment of the present invention includes the following steps:
step S21: the wire controller inquires and registers the air conditioner indoor unit with the dialing address in the group.
In the method provided by the embodiment of the invention, the group of air conditioner internal machines controlled by the wire controller has the air conditioner internal machines with dial addresses and the air conditioner internal machines without dial addresses, wherein the air conditioner internal machines without dial addresses are that dial switches used for setting addresses and functions of part of air conditioner internal machines are removed, and only one-bit dial switches are reserved for setting the attributes of a host machine or a slave machine. The air conditioner internal machine with the dial switch is set as a slave machine, the controller directly controls the host machine, and other internal machines in the group can monitor the control instruction sent by the wire controller from the communication wire and judge the returned information returned by the air conditioner internal machine to realize the control of all the air conditioner internal machines in the group by the wire controller.
The wire controller inquires the dial address in the group, namely inquires the air conditioner indoor unit with the dial address, registers the air conditioner indoor unit according to the dial address, inquires the information of the air conditioner indoor unit, exits the initialization process based on the inquired information, and enters a normal communication process.
Step S22: and assigning addresses for the air conditioner indoor units without dialing addresses in the group.
The air conditioner indoor unit without the dial address cannot define the address by using the dial, and if the control of the air conditioner indoor unit without the dial address is to be realized, the address needs to be assigned.
Because the communication addresses of each air conditioner internal unit and the air conditioner external unit in the same group are uniquely corresponding, the air conditioner internal unit without the dial address can be determined by inquiring the internal and external communication addresses of the air conditioner internal unit and the air conditioner external unit.
In step S21, if the air conditioner internal unit with the dial address is already registered, the communication address of the internal and external units corresponding to the air conditioner internal unit with the dial address may be excluded from being queried. After the air conditioner is eliminated, the wire controller sends a query instruction to the air conditioner indoor unit with the communication address of the indoor unit and the air conditioner indoor unit which receives and replies the query instruction is determined to be the air conditioner indoor unit without the dial address. Specifically, according to the sequence of the communication addresses of the internal and external machines, sequentially sending query instructions to the air conditioner internal machines without dialing addresses, wherein the query instructions at least comprise information of the communication addresses of the internal and external machines, for example, the communication addresses of the internal and external machines are 03-64, starting from 04, sequentially sending the query instructions comprising the 03-64 address information to the air conditioner internal machines in the group, judging whether the query instructions are sent to the air conditioner internal machines of the query instructions, if so, replying information, and after receiving the reply information, sequentially delegating the unregistered minimum internal address to the air conditioner internal machines without dialing addresses of the reply query instructions, for example, taking a 16-system address as an example, the address 0000 is a host dialing address, 0001 and 0002 are dialing addresses of the air conditioner internal machines with dialing addresses at two parts, respectively, and starting from 0003, delegating the unregistered address in the group to the air conditioner internal and external machine with the communication address of 0003 as 03, 0004, assigning the address in the group to the air conditioner indoor unit with the communication address of the indoor unit and the communication address of the outdoor unit being 04 until the last air conditioner indoor unit which replies the query command is assigned the address in the group.
Step S23: and registering the air conditioner indoor unit without the dialing address in the group according to the delegation address.
After the addresses are delegated, each air conditioner indoor unit in the group has a unique in-group address, and when the wire controller controls a plurality of indoor units, each air conditioner indoor unit can be controlled based on the in-group addresses, namely, the communication protocol comprises functional instruction codes and address codes, so that the control of the target air conditioner indoor unit can be realized. In the prior art, if the control of an air conditioner indoor unit is to be realized, a communication protocol-based code needs to include a functional instruction with a dial setting bit and a dial address code, the instruction code in the communication protocol is obviously limited by the number of bits of a dial switch, when a new function needs to be added or a new air conditioner indoor unit needs to be added, on one hand, the dial switch needs to be additionally arranged on each air conditioner indoor unit, on the other hand, the communication protocol needs to be modified, the control difficulty of a wire controller is increased, and the complexity is increased for later-stage function expansion and maintenance of the air conditioner indoor unit.
After registration, the information of the registered air conditioner indoor units is inquired, initialization is quitted based on the inquiry of the information, and a normal communication flow is entered.
Step S24: and the wire controller controls the air conditioner indoor unit in the group based on the third communication protocol.
In the embodiment of the invention, the communication protocols aiming at the condition that the indoor units of the air conditioners in the group all have dialing addresses comprise a first communication protocol and a second communication protocol, wherein the first communication protocol is used for an original communication protocol without updating or changing the functions of the indoor units of the air conditioners; the second communication protocol is a communication protocol for updating or changing corresponding functions of the air conditioner indoor unit according to the existing dial-up setting; for example, in the first communication protocol, the dial function is set to 00 for the time-on function and 01 for the time-off function, and in the second communication protocol, the dial function is set to 00 to define the static pressure gear number of the unit machine as first gear and 01 to define the static pressure gear number of the unit machine as second gear; the wire controller encodes and sends a control instruction to the air conditioner indoor unit based on the first communication protocol or the second communication protocol, and the encoding needs to include function information with dial setting bits and dial address information.
In the group air conditioner internal units, after the air conditioner internal units without dial addresses are delegated with addresses, each air conditioner internal unit in the group has a unique group address, when the wire controller controls a plurality of internal units, the wire controller encodes a control instruction based on a third communication protocol, then sends the control instruction to the group air conditioner internal units, specifically, sends the control instruction to a host, and other air conditioner internal units in the group can monitor the control instruction from a communication line; the code comprises functional instruction information and delegated address information.
When the control instruction is sent, the wire controller can send the control instruction in a broadcasting mode, and after the indoor unit of the air conditioner in the group receives the control instruction, whether the control instruction is the instruction sent to the wire controller is judged, and then the control instruction is executed; or the control instruction can be sent to the host computer firstly, the host computer broadcasts to the slave computer, and the slave computer judges whether the instruction is sent to the slave computer and then executes the instruction; two ways, there is a difference in hardware connections; here, the slave is a non-dial-up air conditioner internal unit to which an address is delegated and an air conditioner internal unit to which a dial-up address is assigned.
After the on-line controller controls the air conditioner internal unit based on the third communication protocol, step S25 is executed: the wire controller judges whether an additional air conditioner indoor unit appears in the group according to the set frequency; and step S26: if so, registering the additional air conditioner indoor unit and controlling the additional air conditioner indoor unit based on the third communication protocol.
The added air conditioner internal units comprise air conditioner internal units with dial addresses and air conditioner internal units without dial addresses.
For the two types of additional air conditioner internal units, the judgment is also divided into two types, as shown in fig. 2, the method comprises the following steps:
step S31: and sending an inquiry instruction of the air conditioner internal unit added with the dial address to the air conditioner internal unit in the group according to the set frequency.
If the air conditioner internal unit with the dial address is added in the group, the added air conditioner internal unit monitors the query instruction of the type, judges that the query information is sent to the air conditioner internal unit, and replies the instruction.
Step S32: and if the wire controller receives the reply information of the air conditioner internal unit with the additional dialing address, registering the air conditioner internal unit with the additional dialing address.
And after the registration is finished, entering normal communication.
Step S33: and sending an inquiry instruction of the air conditioner indoor unit without the dial address to the air conditioner indoor units in the group according to the set frequency based on the communication addresses of the indoor unit and the outdoor unit.
In the same way, based on the uniqueness of the communication addresses of the air conditioner indoor unit and the air conditioner outdoor unit, the air conditioner indoor unit without the dial address can be inquired by inquiring the internal and external communication addresses of the air conditioner indoor unit and the air conditioner outdoor unit. Because all the air conditioner indoor units without dialing have delegated addresses, if a new indoor unit air conditioner is added, the newly added indoor unit air conditioner corresponds to an indoor unit and outdoor unit communication address, but does not have an in-group address, after the type of query instruction is monitored, the query instruction is judged to be sent to the air conditioner indoor units, and the instruction is replied. And is thus queried.
Step S34: and if the reply information of the air conditioner indoor unit without the additional dialing address is received, assigning the group internal address for the air conditioner indoor unit without the additional dialing address.
In the same manner, the unregistered minimum group address is sequentially delegated to the additional dial-less air conditioner indoor unit.
Step S35: and registering the additional dial-up-free air conditioner indoor unit according to the delegation address.
After the registration is finished, the information of the additional dial-up-free air conditioner indoor unit is inquired, and normal communication is carried out.
In the method for controlling the air conditioner internal unit by the line controller provided by the embodiment of the invention, in order to realize generalization and enable the control of the line controller on the air conditioner internal unit to be adaptive to the control mode of the prior art, and the control mode provided by the embodiment of the invention, the step S11 is executed before the air conditioner internal unit with dial codes in the register group is registered.
Step S11: the wire controller judges the protocol dialing state of the wire controller.
Installing a protocol dial on the online controller for distinguishing the states of the air conditioner internal units in the group; by combining the control mode in the prior art and the control mode provided by the invention, the air conditioner internal units in the group are divided into two conditions: 1. all the indoor air conditioners in the group are indoor air conditioners with dial switches, and the dial setting of each indoor air conditioner is used for defining addresses and functions; executing a first communication protocol or a second communication protocol; 2. the air conditioner internal units not only comprise dialing addresses, but also comprise air conditioner internal units without dialing addresses, a host is defined in the air conditioner internal units without dialing addresses, and other air conditioner internal units comprising dialing addresses and the air conditioner internal units without dialing addresses are all slave machines to execute a third communication protocol.
When the protocol dial is in the on state, it indicates that all the indoor units in the group have dial switches and the communication protocol has not been updated or changed, step S12: the line controller controls the air conditioner indoor units based on the first communication protocol, if the closed state indicates that the air conditioner indoor units in the group are either to update or change the function definition or to add an air conditioner indoor unit without a dial-up address, the line controller needs to control the air conditioner indoor units based on the second communication protocol or the third communication protocol, and then step S21 is executed.
The setting of the characterization opening and closing states is set according to actual use conditions, and the embodiment of the invention is not limited.
Further, if the protocol dialing is in the off state, the following steps are continuously executed:
step S13: and the wire controller sends inquiry broadcast to the indoor unit of the group air conditioner.
The broadcast contains information representing a third communication protocol, if the air conditioner indoor unit without dialing exists in the group, the air conditioner indoor unit without dialing receives the query broadcast, judges that the broadcast is added with the information representing the third communication protocol, sends a reply to the wire controller for confirmation, and after receiving the reply, the wire controller determines that the air conditioner indoor unit without dialing actually exists in the group, and needs to control the air conditioner indoor unit based on the third communication protocol, and executes the step S21; if no dial-up air conditioner indoor unit exists in the group, the wire controller cannot receive the reply, and the wire controller confirms that no dial-up air conditioner indoor unit exists in the group and controls the air conditioner indoor unit in the group based on the second communication protocol.
In the method for controlling an air conditioner internal unit by a wire controller provided by the embodiment of the invention, a group of air conditioner internal units controlled by the wire controller not only include an air conditioner internal unit with a dial-up address, but also include an air conditioner internal unit without a dial-up address, only one dial-up bit is reserved on the air conditioner internal unit without the dial-up address to set the attribute of a host or a slave of the air conditioner internal unit, the air conditioner internal unit with the dial-up address is a slave, the host is directly controlled by the wire controller, the wire controller sends a coded control instruction to the host, and other slaves can monitor the control instruction from a communication line. When the wire controller controls the air conditioner indoor units in the group, firstly inquiring the dial addresses in the group, finding the air conditioner indoor units with the dial addresses to register and initialize, then judging the air conditioner indoor units without the dial addresses according to the uniqueness of the communication addresses of the air conditioner indoor units and assigning the air conditioner indoor units without the dial addresses to the unregistered minimum group address in sequence and registering; because each air conditioner indoor unit in the group has the group address, the wire controller sends the control instruction coded based on the third communication protocol to the host, and the slave machine judges whether the control instruction is the instruction required to be executed by the slave machine after monitoring the control instruction from the communication line. And in the control command based on third communication protocol coding, do not include dial information, only include address information and functional information, just also do not receive the restriction that dial switch set up, when needs increase new function to the air conditioner indoor unit in group, perhaps when needs increase new air conditioner indoor unit, only need the communication protocol in the line control ware of renewal, need not to increase new dial switch to all air conditioner indoor units in the group, this has reduced the control degree of difficulty, make things convenient for line control ware to the control of air conditioner indoor unit in group, management and upgrading, maintenance etc., product quality has been improved.
It should be noted that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should also make changes, modifications, additions or substitutions within the spirit and scope of the present invention.
