Fig. 1 is a schematic diagram of an air conditioner indoor unit controller and a message processing method of the same applied to an air conditioning system.
As shown in fig. 1, the air conditioning system 10 includes an air conditioning unit 11 and a drive-by-wire 12 with a display screen. The air conditioning unit 11 is divided into an outdoor unit 21 and an indoor unit 22. The indoor unit 22 and the outdoor unit 21 have respective unit controllers 23, which are referred to as an air conditioner indoor unit controller 231 and an outdoor unit controller 232. The unit controller 23 is responsible for controlling the air conditioning unit 11. The air conditioner indoor unit controller 231 is responsible for controlling the indoor unit 22. The outdoor unit controller 232 is responsible for controlling the outdoor unit 21. The indoor unit controller 231 of the air conditioner is typically connected to a drive-by-wire 12 with a display screen. The liquid crystal screen of the drive-by-wire 12 is used for user operation. The line controller 12 is provided on a wall.
The air conditioner indoor unit controllers 231 may have a one-to-one correspondence with the line controllers 12. In one application scenario, one room is provided with one air conditioner indoor unit controller 231 and one line controller 12. The air conditioner controller 231 may have a one-to-many correspondence or a many-to-one correspondence with the line controller 12. In one application scenario, an air conditioner indoor unit controller 231 and a plurality of line controllers 12 are disposed in a building. In another application scenario, a plurality of air conditioner controllers 231 and one line controller 12 are provided in one room. The foregoing is merely illustrative and is not intended to be limiting in any way.
The message processing method of the air conditioner indoor unit controller to the wire controller can be applied to the air conditioner indoor unit controller. The following describes an application of the message processing method of the wire controller to the air conditioner indoor unit controller in the air conditioning system.
Fig. 2 is a flow chart illustrating a message processing method of an air conditioner indoor unit controller to a wire controller according to an embodiment of the present application.
As shown in fig. 2, the message processing method of the air conditioner controller to the line controller may include the following steps 110 to 140:
at step 110, a communication message is determined for communication with the drive-by-wire.
The communication message refers to a message that the air conditioner indoor unit controller communicates with the line controller. The communication message is transmitted or received in accordance with a specified communication protocol. The specified communication protocol includes the communication protocol and the communication protocol content of the communication protocol.
Step 120, determining the communication protocol of the wire controller according to the communication message.
The communication protocol of the line controller may include one or more of a general communication protocol, a communication protocol of an air conditioner manufacturer, and a communication protocol of a line controller manufacturer. By way of example, the general communication protocol may be Modbus. The communication protocol of the air conditioner manufacturer is TRANE AP, and the communication protocol of the air conditioner provider is a provider customized protocol. The vendor may be a drive-by-wire vendor and/or a liquid crystal display vendor.
The step 120 may further include reading the protocol type identifier Pro to determine the communication protocol according to the communication message. And analyzing a specific protocol in the communication protocol type of the line controller according to the protocol type identifier Pro to obtain the communication protocol of the line controller. The communication protocol of the wire controller comprises a communication protocol expressed as Mod, a communication protocol expressed as air conditioner manufacturer by TAP/IMC and a communication protocol expressed as vendor custom by VEN. Therefore, the communication protocol of a liquid crystal screen manufacturer or a wire controller manufacturer does not need to be changed, and the communication protocol of an air conditioner manufacturer does not need to be modified.
Step 130, under the condition that the communication protocol of the wire controller is different from the communication protocol of the air conditioner indoor unit controller, obtaining a pre-established protocol analysis relation with the communication protocol of the wire controller according to the communication protocol of the wire controller.
The protocol analysis relation is a communication protocol of a line controller taken from an air conditioner supplier and is established with a communication protocol of an air conditioner indoor unit controller. Therefore, the controller of the air conditioner indoor unit analyzes the communication message to obtain the message content, and communicates with the wire controller, so that the protocol of the controller of the air conditioner indoor unit is not required to be leaked to an air conditioner provider, and the air conditioner provider is not required to change the communication protocol of the liquid crystal display. Meanwhile, because the air conditioner suppliers are limited and the communication protocols are limited, the method is convenient and quick to establish the protocol analysis relation and is beneficial to the use of the follow-up protocol analysis relation. The protocol analysis relation can be configured into a configuration file, and the configuration file describes the communication protocol and the communication content of the wire controller to the air conditioner indoor unit controller, and can also convert the communication content into the content which can be identified by the wire controller. For example, the configuration file may indicate to the air conditioner controller what the communication format required by the line controller is, such as a communication rate, a length of each data packet, whether there is a check, and so on.
The communication protocol of the controller of the air conditioner can be a general communication protocol or a communication protocol of an air conditioner manufacturer, and at this time, the communication protocol of the wire controller is not a standard protocol, is not a communication protocol of the air conditioner manufacturer, but is a communication protocol defined by a provider. In the case that the communication protocol of the wire controller is different from the communication protocol of the air conditioner indoor unit controller, the communication protocol of the wire controller is a communication protocol defined by a provider. And obtaining a protocol analysis relation of a pre-established communication protocol according to a communication protocol defined by a provider so as to realize conversion between the communication protocol of the air conditioner indoor unit controller and the communication protocol of an air conditioner provider.
Under the condition that the communication protocol of the wire controller is the same as that of the air conditioner indoor unit controller, the communication between the wire controller and the air conditioner indoor unit controller can be realized, and the protocol analysis relation is not needed. The method further comprises the step of analyzing the communication message according to the communication protocol of the air conditioner indoor unit controller to obtain the message content under the condition that the communication protocol of the wire controller is identical to the communication protocol of the air conditioner indoor unit controller. Example one: the communication protocol of the wire controller and the communication protocol of the air conditioner indoor unit controller are all universal communication protocols. Example two: the communication protocol of the wire controller and the communication protocol of the air conditioner indoor unit controller are both communication protocols of air conditioner manufacturers.
The protocol analysis relationship may include analysis relationship of communication format, analysis relationship of communication content, and transmission sequence of data.
Illustratively, the parsing relation of the communication format may include that B-12/24/48/96/192/… …/1152 represents the baud rate, L (en) -8/9/10/… represents the data length, and P (ar) -O/E represents the parsing relation of the odd/even parity and other communication formats. Other communication formats such as B12-L8-PO, although other communication protocols may be used in other ways, and are not illustrated in detail herein.
Illustratively, the transmission order of the data and the parsing relation of the communication content may include the following:
1) The drive-by-wire receives the RX start.
RX

R2……………
…………………
Rn……………。
T represents temperature, e.g., T12 represents 1 byte, decimal point 2 bits.
H represents humidity, e.g., H11 represents 1 byte, decimal point 1 bit.
S represents fan speed, e.g., SH/S1 represents high speed, SM/S2 represents medium speed, and SL/S3 represents low speed.
TM represents timing, such as TM365 represents 3 hours, 6 minutes, 5 seconds.
MO stands for mode, e.g. MOH stands for heating, MOC stands for cooling, and MODH stands for dehumidification.
Other contents than T, H, S, TM are possible and are not exemplified here.
2) The line controller transmits TX start:
TX
T1……………
T2……………
…………………
Tn……………。
temperature T03 represents temperature 03
Humidity H04 represents humidity of 04
The fan speed S05 represents a speed of 05
R1 corresponds to T1, i.e., after T1 exits, R1 is expected to be received; r2 and T2 should be in correspondence, i.e. after T2 has gone out, R2 is expected to be received. And so on, which are not described in detail herein.
Example one:
RX
R1-T11-H11-S1 represents that the received data sequence is temperature, humidity and high speed;
R2-MOH-STR3ABC, representing that the received data sequence is heating, STR3ABC representing 3 characters ABC, see section 3 below. ABC may be some characters specified by the vendor protocol, may be meaningful, or may be ignored.
If ABC is of interest, then an example of ABC is as follows: ERROR 1; ABD: ERROR 2; BCE: an unrecognizable air conditioner indoor unit controller command, and the like.
TX
T1-T03-H04-S05, the data sequence sent is 03, 04, 05, the data sequence is temperature, humidity and rotating speed;
T2-MO06 represents that the order of data sent is 06, this data being pattern.
3) STR n represents a communication of n bytes. If received, it may be ignored; if so, transmitting according to the definition below; such as TX STR3ABC, representing ABC three characters.
4) Configuring a transmission order RX and a reception order TX. Defining how many groups of data are received at a time and then sent; or how many sets of data are sent at a time and received. The controller of the air conditioner generally receives R1 and then sends T1; then if R2 is received, T2 is returned. The line controller may need to send multiple sets of data before the air conditioner indoor unit controller replies.
Examples:
example one: R1-R2-R3 represent each time R1, R2 and R3 are received and then sent;
T1-T2-T3, representing one transmission at a time, in the order T1, T2, T3.
Example two: R12-R23 represent two at a time, in the order of R1, R2 and R2, R3;
T12-T23, two at a time, in the order T1, T2, and T2, T3.
Example three: RALL-1-3-2-4 represents each total acceptance, in the order R1, R3, R2, R4;
TALL-1-3-2-4 represents the sequence of T1, T3, T2, T4 for each complete transmission.
In some practical use processes, the air conditioner indoor unit controller 231 can be used as a master, and the wire controller 12 can be used as a slave to realize communication. In other practical use processes, the wire controller 12 may be used as a master, and the air conditioner indoor unit controller 231 may be used as a slave to realize communication. Based on the protocol analysis relation, the protocol analysis relation also comprises the analysis relation of the master and slave machines. Wherein M represents a master and S represents a slave. If M, the controller 231 is the host and the wire controller 12 is the slave; if S, the controller 231 is the slave and the drive-by-wire 12 is the master.
In the step 130, obtaining a protocol parsing relation pre-established by a communication protocol with the drive-by-wire controller further includes first determining a parsing relation of the master-slave machine. Second, an analytical relationship of the communication format is determined. Thirdly, determining the transmission sequence of the data and the analysis relation of the communication content to determine the communication protocol.
And 140, generating and loading a configuration file according to the protocol analysis relation.
And step 150, analyzing the communication message according to the configuration file to obtain the message content.
As shown in fig. 2, the step 110 includes receiving a request message input by the wire controller. The transmission sequence includes a reception sequence and a transmission sequence. The step 140 may further include step 1, determining that the request message is a read request message according to the analysis relation of the communication format, where the read request message is used to read data of the air conditioner indoor unit controller. And 2, generating and loading a configuration file of the reading request message according to the analysis relation and the receiving sequence of the communication content. And 3, analyzing the reading request message according to the configuration file of the reading request message to obtain the content to be read. The method also comprises a step 4 of responding to the reading request message according to the sending sequence and transmitting the content to be read to the wire controller. The request message is determined according to the requirement of the line controller, and the content to be read is the content required by the read request message. Therefore, the method can provide needed contents to be read for the wire controller during communication, so that analysis of the inside of the air conditioner indoor unit controller is realized, and leakage of protocols of the air conditioner indoor unit controller is avoided.
And step 1, determining the analysis relation of the master and slave machines according to the analysis relation of the communication format, and determining the request message as a reading request message. The step 3 includes responding to the read request message according to the sending sequence, and packaging the content to be read according to the communication protocol of the line controller. And transmitting the packaged content to be read to the wire controller.
As shown in fig. 2, the step 110 includes receiving a request message input by the wire controller. The transmission sequence includes a receiving sequence, and the step 140 may further include a first step of determining that the request message is a write request message according to an analysis relationship of the communication format, where the write request message is used to write data into the air conditioner indoor unit controller. And a second step of generating and loading the configuration file of the writing request message according to the analysis relation and the receiving sequence of the communication content. And thirdly, analyzing the writing request message according to the configuration file of the writing request message to obtain the content to be written. The method further comprises a fourth step of responding to the writing request message and obtaining a control instruction according to the content to be written. And fifthly, controlling the indoor unit according to the control instruction, wherein the indoor unit is connected with an air conditioner indoor unit controller. The request message is determined according to the demand of the drive-by-wire controller, and the content to be written is the writing content required by the writing request message. Therefore, the content to be written can be written into the air conditioner indoor unit controller during communication, so that analysis of the inside of the air conditioner indoor unit controller is realized, and leakage of a protocol of the air conditioner indoor unit controller is avoided.
The first step is to determine the analysis relationship of the master and slave according to the analysis relationship of the communication format, and determine that the request message is a write request message.
The method includes 1, reading a first part of a first row of a configuration file, wherein if the analysis relation of a master machine and a slave machine is M, a host controller is used as a host, and a line controller is used as a slave machine; the second row determines the analysis relation of the communication format, and the third row determines the transmission sequence of the data and the analysis relation of the communication content. 2. The third part of the configuration file is read and the transmission order RX and the reception order TX are determined. 3. The second portion of the configuration file is read and the communication content of each transmit R and each receive T is determined. 4. The calling communication program uses the configuration file to transmit and receive, so that the communication program can be used for running the content of the configuration file.
One example of the practical application. Step 1, the temperature of the wire controller needs to be checked, and the controller of the air conditioner indoor unit receives a temperature inquiry request input by the wire controller. And 2, determining a request of temperature inquiry as a read request message by the air conditioner indoor unit controller, and determining an analysis relation of the master machine and the slave machine as S according to the read request message, wherein S represents the air conditioner indoor unit controller as a slave machine and the line controller as a master machine. And determining an analytic relationship of the communication format and determining the communication content. And step 3, the controller of the air conditioner indoor unit reads the current temperature, responds to the temperature inquiry request according to the sending sequence, and transmits the current temperature to the wire controller.
Two examples in practical application.
