Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the technical solutions of the present invention is provided with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an embodiment of the present invention provides a control method for a universal controller of an air conditioner, including the following steps:
the method comprises the steps that the type of an air conditioner to be controlled is obtained, wherein the type comprises a single system and a double system;
processing a data frame to be transmitted according to the model to obtain a pre-transmission data packet;
and controlling the host to sequentially send request frames to the slave according to the pre-sent data packet.
The control method of the universal controller for the air conditioner, provided by the embodiment of the invention, comprises the steps of firstly obtaining the type of the air conditioner to be controlled, then respectively carrying out different processing according to the type of a single system and the type of a double system of the air conditioner to be controlled to obtain pre-sent data packets, and finally controlling a host to sequentially send request frames to a slave according to the pre-sent data packets. The scheme machine type of the application processes the data frame to be sent so as to solve the problems that the data frame transmitting process easily causes communication stagnation when the double-system air conditioner is controlled and the network data packet contains redundant data when the single-system air conditioner is controlled.
As a supplementary explanation to the above-described embodiment, acquiring the model of the air conditioner to be controlled includes: and acquiring the type of the air conditioner to be controlled through dialing. Specifically, the protocols of the air conditioner single-double system are classified, and the host identifies different machine types through dialing.
In some alternative embodiments, if the system model is single system, the data frame of one system is removed to obtain the pre-transmission data packet.
In other optional embodiments, if the system model is a dual system, a frame of data of a data frame to be transmitted is divided into multiple frames of data to obtain a pre-transmission data packet.
It should be noted that, the data content of a frame to be sent by the dual system is more and disordered, and includes data with different functions. Therefore, dividing one frame data of a data frame to be transmitted into multi-frame data includes: dividing one frame of data of a data frame to be sent into multi-frame data according to the function of the data so that each frame of data of the multi-frame data corresponds to one function code. Illustratively, data in one kind of data is divided into data of multiple frames according to state quantities, parameter quantities and the like.
And after the data to be transmitted are processed according to the model, the request frames are sequentially transmitted to the slave machines.
As an optional implementation manner of the embodiment of the present invention, a single system machine type directly sends request frames to a sending terminal in sequence. In the dual-system type, the host is controlled to sequentially send request frames to the slave according to the pre-sent data packet, so that different frame data corresponding to different function codes are sent in a time-sharing manner.
Illustratively, the protocol for a single-double system employs a classification process. The host identifies different types of the data through dialing codes, and then the data are divided into single-system network data packets or double-system network data packets for respective data processing. The data as transmitted includes data of system 1 and system 2
If the dial-up machine type is a single system, data is properly cut, namely, a data frame of the system 2 is cut, only a network data packet of the system 1 is sent, the total sending time can be 3ms originally, redundant data is cut, the total sending time can be 1.5ms at the moment, the communication network efficiency can be greatly improved, and the total communication time can be further reduced;
when the dial-up model is a dual system, the host data packet is sent in time-sharing and multi-frame mode, different frames are distinguished through the function codes, one frame is divided into multiple frames, such as state quantity, parameter quantity and the like, and different frames corresponding to different function codes are sent in time-sharing mode, so that the data accuracy is ensured, and communication stagnation caused by overlong data frames can be avoided.
The structure of the request frame is shown in fig. 2, and the outdoor motherboard 20 is used as a host, and the order of the request frame transmission is from left to right, and the request frame transmission sequentially goes to the first display panel 21, the first internal motherboard 22, the second display panel 23, the second internal motherboard 24, and the debugging tool 25. First, a request frame is sent to the first display panel 21, and in the case of normal communication, the first display panel returns a response frame after receiving the request frame. In the prior art, in order to ensure that the time for sending the request frame to the first internal machine motherboard is after receiving the first response frame, delay sending is usually set, that is, the time for sending the request frame to the next slave is later than the time for receiving the response frame returned by the current slave. When communication is abnormal, the returned response frame cannot be received, and the next slave computer sends a request frame after the time point of delayed sending is exceeded. However, for the slave machine of the debugging tool type, the slave machine itself has no influence on the normal use of the air conditioner, but if a communication fault occurs, the slave machine needs to wait for the delay time, which wastes time and reduces the communication efficiency.
In order to solve the above problem, as shown in fig. 3, the embodiment of the present invention further includes determining whether to control the master to send the request frame to the slave according to the type of the slave if the master does not receive the response frame after exceeding a preset time.
In some optional embodiments, if the slave is a debugging tool, the control host does not send the request frame to the slave after the response frame is not received in the preset time. It should be noted that the debugging tool is used as a parameter of a debugging manufacturer, and is debugged only before leaving the factory, and the air conditioning unit after leaving the factory does not have the element.
In other optional embodiments, if the slave is a non-debug tool, the slave sends out a communication fault alarm and continues to send a request frame to the slave after not receiving the response frame for a preset time. The non-debugging tool is a slave machine with the debugging tool removed, and illustratively, an internal machine mainboard and a display panel.
Illustratively, the traditional Modbus RTU communication network is adopted, the host respectively calls the slave machines, but under the condition of more slave machines, the communication efficiency is low, and the time consumption for calling each time is long after one round of calling is finished, so the invention also discloses a processing mode of the communication network,
as for the non-debugging tool of the air conditioner, the slave machine is an internal machine or a display panel, and as an essential factor of the air conditioner, the master machine always names the slave machine, if the 30S slave machine does not respond to a data packet, the master machine reports a communication fault, and if the slave machine responds, the communication is recovered to be normal.
The slave machine is a debugging tool and is only used as a parameter of a debugging manufacturer, the debugging is only carried out before the slave machine leaves the factory, the air conditioning unit after leaving the factory does not have the element, if a control method of a non-debugging tool is adopted, the debugging tool is called at a time point which wastes one frame, therefore, a request frame is sent to the debugging tool within 30S after the host machine is initially electrified, and if the debugging tool has a response frame, the communication is normal; if the host does not receive the response frame of the slave in 30, the host cuts off the request frame (the request frame refers to the host roll call debugging tool), and the rest remains unchanged (the rest refers to the host roll call inner unit and the display panel), so that the communication efficiency is improved.
The embodiment of the invention adopts a self-defined protocol, carries out protocol classification on data of single and double systems, carries out time-sharing and framing transmission on data packets of the double systems, properly cuts the data packets of the single system, changes the control mode of a request frame of a host, and cuts off the request if unnecessary slave machines do not respond within preset time, thereby improving the communication efficiency and the communication real-time property.

If the system model is a dual system, the data processing module divides one frame of data of the data frame to be sent into multi-frame data to obtain a pre-sent data packet. The data processing module divides one frame of data of a data frame to be sent into multi-frame data according to the function of the data, so that each frame of data of the multi-frame data corresponds to one function code.
And a request frame sending module 43, configured to control the master to send request frames to the slaves in sequence according to the pre-sent data packet. Specifically, for a dual-system model, the request frame sending module sends different frame data corresponding to different function codes in a time-sharing manner.
As an optional implementation manner of the embodiment of the present invention, if the response frame is not received after the preset time, the request frame sending module determines whether to send the request frame to the slave according to the type of the slave.
If the slave is a debugging tool, the request frame sending module does not send the request frame to the slave after the response frame is not received in the preset time.
If the slave is a non-debugging tool, the request frame sending module sends out a communication fault alarm and continues to send the request frame to the slave after the response frame is not received in the preset time.

The data processing module respectively processes the data packets to be sent of the single system and the double systems, and the communication bus efficiency is improved. Meanwhile, the request frame sending module changes the sending mode of the request frame, so that the real-time performance of communication is improved, and the real-time data acquisition is ensured.
