Country also proposed relevant national standard draft, in a manner of specification Master Communications, promote the hair of intelligent appliance technology
Exhibition, but it is all-embracing as being needed for national standard, and actual conditions need to formulate the communication of the compatibility but non-redundancy that meet national standard
Agreement.
Intelligent chip, i.e. system level chip (System on Chip；SOC), it is mainly used for storing and processing household appliance
Operating status, control logic and intelligent logic chip.
Traditional die, i.e. micro-control unit (Microcontroller Unit；MCU), mainly for the treatment of household appliance
Basic control and household appliance operating status chip.
Summary of the invention
The technical problem to be solved by the present invention is to：It proposes a kind of Master Communications method in intelligent appliance equipment, solves mesh
The problem of preceding all kinds of intelligent appliance equipment Master Communications are incompatible, influence intellectualized technology development.
The technical solution adopted by the present invention to solve the technical problems is：Master Communications method in intelligent appliance equipment, packet
Include following steps：
A, serial ports is initialized, intelligent chip automatically selects and the corresponding serial ports configuration of traditional die；
B, intelligent chip determines according to the data that traditional die returns to traditional die sending device decision instruction and uses phase
Answer the configuration and command protocols of product；
C, intelligence instruction is processed into basic control instruction by intelligent chip, to be sent to traditional die execution；
D, intelligent chip timing sends inquiry instruction, query facility operating status to traditional die；
E, traditional die receives and sends current device operating status to intelligent chip after inquiry instruction；
F, intelligent chip and traditional die pass through whether just timing inquiry instruction judges other side's operating status and communication
Often, corresponding failure processing operation is carried out if monitoring failure.
Further, in step F, the corresponding failure processing operation includes：Restart or reconnects.
The beneficial effects of the invention are as follows：Communication protocol meets national standard, solves all kinds of intelligent appliance equipment Master Communications not
Compatible problem is suitable for the intellectual products such as air-conditioning, refrigerator, cigarette stove and all kinds of small household appliances.
Detailed description of the invention
Fig. 1 is embodiment master control communication work flow chart；
Fig. 2 is embodiment master control communication instruction agreement.
Specific embodiment
The present invention is directed to propose a kind of Master Communications method in intelligent appliance equipment, solves all kinds of intelligent appliance equipment at present
The problem of Master Communications are incompatible, influence intellectualized technology development.
Embodiment：
Master Communications method in this example includes：
Step 1: initialization serial ports, intelligent chip is automatically selected and the corresponding serial ports configuration of traditional die；
Step 2: intelligent chip is determined to traditional die sending device decision instruction according to the data that traditional die returns
Using the configuration and command protocols of corresponding product；
Step 3: intelligence instruction is processed into basic control instruction by intelligent chip, to be sent to traditional die execution；
Step 4: intelligent chip timing (0.5s) sends inquiry instruction, query facility operating status to traditional die；
Step 5: traditional die, which receives, sends current device operating status to intelligent chip after inquiry instruction；
Step 6: intelligent chip and traditional die pass through, timing inquiry instruction judges other side's operating status and communication is
It is no normal, restarted if monitoring failure or the fault handling operations such as reconnection.
As shown in Figure 1, being initialized first to serial ports, to realize that intelligent chip and the corresponding serial ports of traditional die are matched
It sets, then carries out equipment judgement, i.e., it is corresponding logical according to device model selection from intelligent chip to traditional die query facility model
Believe agreement (such as serial ports air-conditioning communication protocol, serial ports refrigerator communication protocol, serial ports smoke machine communication protocol etc.), is determining configuration ginseng
After several and communication protocol, intelligent chip can send corresponding control instruction to equipment, be related among these to serial data packet
Encapsulation with parse and serial data packet sends and receives, instruction be processed into elementary instruction be sent to traditional die and hold
Row.
Serial port communicating protocol between intelligent control chip in the present invention and Traditional control chip, including equipment determine association
View, control protocol, vlan query protocol VLAN, upper datagram protocol.
Equipment determines agreement：Refer to that during master control communication initialization, specific format instruction is sent to MCU, MCU by SOC
Returning equipment type and model are to take corresponding agreement in order to next communicate to SOC.
Control protocol：Refer to the household appliance state that SOC changes needs, is packaged into communication according to national standard consensus standard
Packet is sent to MCU by serial ports, changes household appliance state after MCU parsing.
Vlan query protocol VLAN：Refer to that SOC by specific command status, is packaged into communication packet according to national standard consensus standard, passes through string
Mouth is sent to MCU.
Upper datagram protocol：Refer to that MCU by all operating statuses of household appliance, is packaged into communication packet according to national standard consensus standard,
It is sent to SOC by serial ports, saves household appliance state after SOC parsing.
The specific implementation of the serial communication protocol is as shown in Fig. 2, be below specifically described each component part：
Frame head：Byte1+Byte2 indicates the beginning of a frame, content 0xF40xF5, and frame head length is 2 bytes.
Frame type：Indicate that this frame is what type of frame, inquiry instruction is used for query facility current operating conditions；Setting refers to
