Description of the drawings
Fig. 1 is the structural schematic diagram of the interface duplex system of air-conditioner controller provided in an embodiment of the present invention;
Fig. 2 is the flow chart of the method for multiplexing interface of air-conditioner controller provided in an embodiment of the present invention.
Specific implementation mode
As shown in Figure 1, in the embodiment of the present invention, a kind of interface duplex system of air-conditioner controller is provided comprising empty
Controller 1 and protection switch 2 are adjusted, the air-conditioner controller 1 has the temperature-sensitive packet interface 4 for connecting air-conditioning temperature sensing package 3, described
Temperature-sensitive packet interface 4 includes two connecting pins 41, and the protection switch 2 is series at the temperature-sensitive packet interface with the air-conditioning temperature sensing package
Two connecting pins between.
In the embodiment of the present invention, the protection switch 2 is that high voltage protective switch, low-voltage protective switch or overload protection are opened
It closes, for being protected to air-conditioning.
As shown in Fig. 2, the course of work of the interface duplex system of above-mentioned air-conditioner controller is as follows:
The air-conditioner controller 1 is detected the state of the temperature-sensitive packet interface 4, when the temperature-sensitive packet interface 4 state just
Chang Shi, the air-conditioner controller 1 control air conditioner display screen and show the temperature that the temperature sensing package 3 detects;
When the air-conditioner controller 1 detects 4 short circuit of the temperature-sensitive packet interface, the air-conditioner controller 1 judges event at this time
Barrier type is temperature sensing package short trouble, and controls air conditioner display screen and show corresponding failure code;
When the air-conditioner controller 1 detects that the temperature-sensitive packet interface 4 is open circuit, detected again after waiting for a period of time, if
The temperature-sensitive packet interface 4 is also open circuit at this time, then the air-conditioner controller 1 is determined as fault type for temperature sensing package open fault simultaneously
Control air conditioner display screen shows corresponding failure code, if the temperature-sensitive packet interface 4 restores normal at this time, the air-conditioning control
Device 1 processed judges to open a way caused by open circuit reason just now disconnects as protection switch 2, and controls air conditioner display screen and show corresponding event
Hinder code.
It should be noted that when being multiplexed to the temperature-sensitive packet interface 4, because of the usual state of the protection switch
Should be closed, if there is short trouble, be only possible to be that the temperature sensing package 3 short trouble occurs.The temperature-sensitive packet interface 4
When to open a way, it may be possible to which disconnecting caused by protection act occurs in the protection switch, it is also possible to be that the temperature sensing package 3 goes out
Existing open fault, if certain interval of time(Such as 1 minute)Restore normal when being detected again afterwards, then explanation is protection switch
2 disconnect caused by open circuit because protection switch 2 disconnect after, can cause air-conditioning shut down and make trigger protection switch disconnection because
Element restores normal, and then the protection switch 2 is caused to be closed, and if the 2nd detection open fault after certain interval of time
It can restore, then explanation is that protection switchs from abnormal restoring, and if failure cannot be restored, and can only be just temperature sensing package failure
.
In addition, when the air-conditioner controller detects that the temperature-sensitive packet interface is open circuit, acceptable display switch simultaneously
The failure code of the failure code and temperature sensing package open fault of protection, then further judge it is switch according to phenomenon by maintenance personal
Protection or temperature sensing package failure.
In conclusion in the interface duplex system and method for the air-conditioner controller of the present invention, by protection switch and air-conditioning
Temperature sensing package is connected between two connecting pins of the temperature-sensitive packet interface of the air-conditioner controller, according to the signal of temperature-sensitive packet interface into
Row acquisition is multiplexed temperature-sensitive packet interface to judge the state of temperature-sensitive packet interface, to be connect in realization temperature sensing package
While the function of mouth, moreover it is possible to realize the function of protection switch, solve unprotect on airconditioning control mainboard and switch corresponding interface
Problem, without redesigning exploitation control mainboard, you can meet the needs of system increases protection switch, from development cycle and exploitation
It takes advantage in cost, has also saved the both threads of special connection protection switch, material cost is lower.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
