Below with reference to the accompanying drawings display fault control device and the method for the air-conditioner of the embodiment of the present invention are described.
Fig. 1 is the block diagram of the display fault control device of air-conditioner according to the embodiment of the present invention.As shown in Figure 1, the display fault control device of this air-conditioner comprises: display module 10, power module 20 and load driver module 30.
Wherein, display module 10 has first memory 101, and first memory 101 is for storing the running state information of display module 10; Power module 20 is connected with display module 10, and power module 20 is for powering for display module 10; Load driver module 30 shows for driving display module 10, and load driver module 30 intercoms with display module 10 phase, and load driver module 30 has second memory 301, stores preset operating state information in second memory 301.According to the present invention's concrete example, communicate by physical circuit between load driver module 30 with display module 10, also communicate by wireless mode.
Load driver module 30 obtains the current operating conditions information of display module 10, and current operating conditions information and preset operating state information are compared, and restart according to comparison result control power module 20 pairs of display modules 10, or resetted by the reseting pin control display module 10 of display module 10.That is, load driver module 30 can change the power supply state that power module 20 is powered to display module 10, and now, load driver module 30 can be connected with power module 20; Or load driver module 30 also can change the level state of the reseting pin of display module 10 inside, now, load driver module 30 can be connected with the reseting pin of display module 10.
Wherein, it should be noted that, display module 10 can show the running status of air-conditioner, and wherein, the running status of air-conditioner can comprise operational mode, target temperature and wind-speed gear etc.
In air-conditioner running, the running state information of oneself can be sent to load driver module 30 by display module 10, after load driver module 30 receives the running state information of display module 10, this status information and preset operating state information are contrasted, if comparison result shows that display module 10 breaks down and such as shows fault etc., then load driver module 10 disconnects the connection between display module 10 and power module 20, namely control power module 20 to stop powering for display module 10, and closed connection between display module 10 and power module 20 after Preset Time, namely control power module 20 again to power for display module 10, or load driver module 30 is to the low level of the reseting pin output Preset Time of display module 10.
Thus, the display fault control device of the air-conditioner of the embodiment of the present invention, load driver module 30 is after the current operating conditions information obtaining display module 10, current operating conditions information and preset operating state information are compared, and restart according to comparison result control power module 20 pairs of display modules 10, or control display module 10 by reseting pin to reset, thus, when display module 10 breaks down, load driver module 30 can autoboot or reset display module 10, realize autonomous judgement and the process of fault, guarantee the result of use of user, promote the experience of user.
According to a specific embodiment of the present invention, preset operating state information is the state value that display module may occur, if current operating conditions information is not in preset operating state information, then load driver module 30 controls power module 20 pairs of display modules 10 and restarts, or controls display module 10 by reseting pin and reset.
In air-conditioner running, the running state information Sr of oneself can be sent to load driver module 30 by display module 10, after load driver module 30 receives the running state information Sr of display module 10, judge that whether running state information Sr is at preset operating state information Tr, if running state information Sr is not at preset operating state information Tr, then show that display module 10 breaks down and such as show fault etc., load driver module 10 controls power module 20 and to stop power supply Preset Time, or the level controlling reseting pin maintains low level Preset Time.

That is, if in the state value Tr that the current operating conditions information Sr of display module 10 may occur at display module, then illustrate display module 10 normally, do not break down, current operating conditions information Sr is kept in second memory 301 by load driver module 30.Be understandable that, second memory 301 can preserve the current operating conditions of state value that display module may occur and display module, and second memory 301 also can preserve oneself running state information.
In addition, need to be described, running state information can comprise state variable M
iwith the variate-value N of correspondence
i, preset operating state information can be whole state variable P that display module may show
mwith whole variate-value Q that each state variable may occur
n.Display module 10 can by state variable M
iwith the variate-value N of correspondence
ithe form of form following table 1.Further, the data of following table 1 can be transferred to load driver module 30 with the form of array by display module 10, and for example, the status information of operational mode can be transferred to load driver module 30 with the form of [mode, 0x6a] by display module 10.In addition, the state variable that temp can be the state variable of target temperature, speed can be wind-speed gear.
