485 communications and UART communications are mutual exclusions in device, i.e. synchronization, if using 485 communications, UART communications can not be normal
Carry out, if communicated using UART, it is required that UART communications are not disturbed by 485 chips.Therefore, the debugging air conditioner is being used
, it is necessary to which the communication modes of the debugging air conditioner device are controlled, controlled by actual demand according to user during device
For 485 communications or UART communications of required use.
On this basis, continue that the application method is described in detail, with reference to figure 3, the communication modes of the application control
Method may comprise steps of：
S301：Obtain target communication mode.
Except the above-mentioned hardware components provided comprising the application, the debugging air conditioner device also includes display board, button etc. one
A little original conventional func software and hardware parts.
Based on this, communication modes can be provided for user on the display board of debugging air conditioner device by software mode and set
The communication modes of debugging air conditioner device can be arranged to required mode by function, user by button or display board.So as to this
Step obtains target communication mode and is specifically as follows：Receive the target communication mode that user is set by software mode.It is such a
Under scheme, 485 communication port can use 4 core terminals.
In other embodiments of the present invention, can also be by detecting between 485 communication ports of debugging air conditioner device and air-conditioner set
485 communication connection states identify the target communication mode that need to currently use.Under such a scheme, 485 communication port then needs
Using 5 core terminals.
As shown in Fig. 2 the short circuit of core 2 corresponding with 2 pin of core 1 corresponding to 1 pin of 4855 core terminals, so as to core 2
Level signal can be sent to IO detections port (i.e. described 1 pin) by core 1, and the present embodiment passes through one and the IO test sides
The IO detection circuits that mouth connects, such as specifically by certain bleeder circuit MCU energy normal samples can be ensured to the level of I/O port
Signal.

485 communications between unit are connected, i.e., user has accessed 485 communication modes according to its actual demand, therefore, may recognize that use
The target communication mode of person is 485 communications；, whereas if the I/O port level signal collected is low level, then user does not connect
Enter or disconnect 485 communications, such a situation then thinks that the target communication mode of user communicates for UART.
In other embodiments of the present invention, it is also compatible to use both the above scheme, and can be with the target of newest acquisition
Communication modes (may be obtained by receiving set-up mode, it is also possible to obtained by IO detection modes) are defined, and debugging air conditioner is filled
The communication modes put are controlled.It should be noted that when compatibility uses two schemes, may exist same by two kinds of approach
When obtain the situation of target communication mode, can be by carrying out priority setting in advance for this situation, such as assign " by aobvious
Show that plate is set " the higher priority of mode etc., to solve the problems, such as that the target communication mode that two ways obtains is inconsistent.
S302：When the target communication mode is the first communication modes, by the Enable Pin of the communication chip by institute
It is working condition to state communication chip control；Wherein, the in running order communication chip and first communication interface, on
The first communicating circuit that pull-up resistor circuit is formed is used for the communication function for providing first communication modes.

The Enable Pin of communication chip.
The application is especially by debugging air conditioner device MCU IO (with the non-same IO of detection IO above) mouth to 485 chips
Enable Pin be controlled, specifically, the Enable Pins of 485 chips according to the technical requirements of 485 chips, can be controlled for high level or
Low level, make 485 chips in running order, to ensure the normal transmission of 485 data.
In such cases, UART communications by the interference of 485 chips due to that be able to can not be normally carried out, therefore, now, air-conditioning
The effective communication mode that debugging apparatus uses is 485 communication.
S303：When the target communication mode is the second communication modes, by the Enable Pin of the communication chip by institute
It is off working state to state communication chip control；Wherein, second communication interface and the second of pull-up resistor circuit composition
Communicating circuit is used for the communication function for providing second communication modes.
If the target communication mode communicates for UART, to ensure that UART communication signals are not disturbed by 485 chips, and then
Ensure being normally carried out for UART communications, the technical requirements according to 485 chips are needed, by the level state of the 485 chip Enable Pin
Control as the inverse state of above-mentioned state：Low level or high level, it is ensured that 485 chips are in off working state, so as to, now,
The effective communication mode that debugging air conditioner device uses communicates for UART.
From above scheme, disclosed method is applied to debugging air conditioner device, the debugging air conditioner device bag
Include pull-up resistor circuit, communication chip, the first communication interface and the second communication interface；Methods described is by using communication chip
