Description
Technical field
The present invention relates to serial port communication technology, particularly to Master Communications method in intelligent appliance equipment.
Background technology
Along with the development of science and technology, Internet of Things product more and more comes into our life, and intelligent appliance etc. has become a part for our life.Air-conditioning, refrigerator and all kinds of small household appliances add intelligent appliance extended family one after another, but in all kinds of household electrical appliances of current each manufacturer, Master Communications, namely the communication differences between traditional die and intelligent chip is very big, and incompatible, this causes obstruction to the development of "smart" products.
Country it is also proposed relevant GB draft, in the way of specification Master Communications, promotes the development of intelligent appliance technology, but needs all-embracing as GB, and practical situation needs to formulate the compatibility meeting GB but the communication protocol of non-redundancy.
Intelligent chip, i.e. system level chip (SystemonChip；SOC), it is mainly used in storage and processes the running status of home appliance, control logic and the chip of intelligent logic.
Traditional die, i.e. micro-control unit (MicrocontrollerUnit；MCU), mainly for the treatment of the chip of the basic controlling of home appliance and home appliance running status.
Summary of the invention
The technical problem to be solved is: proposes a kind of Master Communications method in intelligent appliance equipment, solves current all kinds of intelligent appliance equipment Master Communications incompatible, the problem affecting intellectualized technology development.
The technical solution adopted for the present invention to solve the technical problems is: Master Communications method in intelligent appliance equipment, comprises the following steps:
A, initialization serial ports, intelligent chip automatically selects serial ports configuration corresponding with traditional die；
B, intelligent chip send equipment decision instruction to traditional die, determine, according to the data that traditional die returns, the configuration and command protocols that adopt corresponding product；
Intellectuality instruction is processed into basic controlling instruction by C, intelligent chip, to be sent to traditional die execution；
The timing of D, intelligent chip sends query statement, query facility running status to traditional die；
E, traditional die send current device running status to intelligent chip after receiving query statement；
Each through timing query statement, F, intelligent chip and traditional die judge that whether the other side's running status and communication be normal, then carry out corresponding failure process operation as monitored fault.
Further, in step F, described corresponding failure processes operation and includes: restarts or reconnects.
The invention has the beneficial effects as follows: communication protocol meets GB, solve the problem that all kinds of intelligent appliance equipment Master Communications is incompatible, it is adaptable to the intelligent artifacts such as air-conditioning, refrigerator, cigarette stove and all kinds of small household appliances.
Accompanying drawing explanation
Fig. 1 is embodiment master control communication work flow chart；
Fig. 2 is embodiment master control communication instruction agreement.
Detailed description of the invention
It is contemplated that propose a kind of Master Communications method in intelligent appliance equipment, solve current all kinds of intelligent appliance equipment Master Communications incompatible, the problem affecting intellectualized technology development.
Embodiment:
Master Communications method in this example includes:
Step one, initialization serial ports, intelligent chip automatically selects serial ports configuration corresponding with traditional die；
Step 2, intelligent chip send equipment decision instruction to traditional die, determine, according to the data that traditional die returns, the configuration and command protocols that adopt corresponding product；
Intellectuality instruction is processed into basic controlling instruction by step 3, intelligent chip, to be sent to traditional die execution；
Step 4, intelligent chip timing (0.5s) send query statement, query facility running status to traditional die；
Step 5, traditional die send current device running status to intelligent chip after receiving query statement；
Each through timing query statement, step 6, intelligent chip and traditional die judge that whether the other side's running status and communication be normal, then carry out, as monitored fault, fault handling operation such as restarting or reconnect.
As shown in Figure 1, first serial ports is initialized, thus realizing intelligent chip and the corresponding serial ports configuration of traditional die, then equipment judgement is carried out, namely by intelligent chip to traditional die query facility model, respective communication agreement (such as serial ports air-conditioning communication protocol is selected according to unit type, serial ports refrigerator communication protocol, serial ports cigarette machine communication protocol etc.), after determining configuration parameter and communication protocol, intelligent chip just can send corresponding control instruction to equipment, this transmission being directed to the encapsulation to serial data bag and parsing and serial data bag and reception, instruction is processed into elementary instruction be sent to traditional die and perform.
The serial port communicating protocol between intelligent control chip and Traditional control chip in the present invention, judges agreement, control protocol, vlan query protocol VLAN, upper datagram protocol including equipment.
Equipment judges agreement: refer to that specific format instruction is sent to MCU, MCU returning equipment type and model to SOC by SOC in master control communication initialization process, in order to next communication is to take corresponding agreement.
Control protocol: refer to that SOC will need the home appliance state changed, be packaged into communication bag according to GB consensus standard, be sent to after MCU, MCU resolve by serial ports and change home appliance state.
Vlan query protocol VLAN: refer to that SOC is by specific command status, is packaged into communication bag according to GB consensus standard, is sent to MCU by serial ports.
Upper datagram protocol: refer to that MCU is by all for home appliance running statuses, is packaged into communication bag according to GB consensus standard, is sent to after SOC, SOC resolve by serial ports and preserves home appliance state.
This serial communication protocol implement as in figure 2 it is shown, below each ingredient is specifically described:
Frame head: Byte1+Byte2 represents the beginning of a frame, and content is 0xF40xF5, and frame head length is 2 bytes.
Frame type: represent that this frame is what type of frame, query statement is used for query facility current operating conditions；Arrange instruction to send for control command and state return；Equipment judges to be used for judging current device type and model.
Frame length: the byte number of whole frame length, query statement is 7 bytes, and equipment decision instruction is 5 bytes, arranges instruction and depends on the circumstances.
Device type, concrete model: SOC end gets the type of current device and concrete model after sending query statement from MCU end.
Instruction type: the type of instruction is set, point single state, multimode and total state three kinds.
Number of instructions: the number of basic controlling order in instruction is set.
Content: the content of basic controlling order in instruction is set.Single status command comprises a command unit, and namely command sequence number (1 byte), byte n (1 byte) shared by command code and command code (n byte) form；Multimode instruction comprises a plurality of command unit；Total state instruction comprises all of command unit.
Verification: all bytes above are added, not calculation overflow.
