Description
Technical field
This utility model is related to refrigerator field, is more particularly to display panel is communicated for refrigerator frequency conversion electrical control integrated board
System.
Background technology
Traditional scheme only has one-way communication mode of the display panel to frequency conversion electrical control plate, the failure of frequency conversion board generally by
The flashing times of the malfunction indicator lamp in frequency conversion board carry out the species of failure judgement, and this mode one side maintainer can not be rapid
Judge the fault type of refrigerator and using corresponding maintenance program, on the other hand, the method for traditional trouble light flicker is unable to body
Reveal concrete each fault-signal, but several fault-signals are classified as one kind, it has not been convenient to maintainer judges to be out of order rapidly
Particular location, increase maintenance time.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of logical with display panel for refrigerator frequency conversion electrical control integrated board
The system of news so that maintainer can carry out breakdown judge by refrigerator display floater.
To solve the above problems, the technical solution adopted in the utility model is：For refrigerator frequency conversion electrical control integrated board with it is aobvious
Show the system that plate is communicated, including compressor, frequency conversion electrical control integrated board and display panel；The frequency conversion electrical control integrated board includes frequency conversion
MCU, main control MCU, the first optocoupler and the second optocoupler, the display panel is driven to include panel MCU and panel；The compressor and institute
State the connection of frequency conversion drive MCU；Frequency conversion drive MCU is connected by first optocoupler with the main control MCU, meanwhile, it is described
Frequency conversion drive MCU is also connected by second optocoupler with the main control MCU；The main control MCU and the two-way companies of the panel MCU
Connect；The panel MCU is connected with the panel.
Further, the panel is for can input display panel.
The beneficial effects of the utility model are：In this utility model, display panel and frequency conversion electrical control plate can both-way communication, when
When driving MCU to produce fault-signal, due to driving MCU to send out the fault-signal for receiving by the second optocoupler, main control MCU
Be sent on display panel and shown, therefore maintainer can carry out breakdown judge by refrigerator display floater, with practicality it is wide,
Reliability is high, breakdown judge accurately advantage, greatly improves the convenience of refrigerator after-sales service.
Description of the drawings
Fig. 1 is the structural representation of embodiment.
Specific embodiment
This utility model is specifically described below by embodiment.
As shown in figure 1, the present embodiment includes compressor, frequency conversion electrical control integrated board, display panel；The frequency conversion electrical control integrated board
Including frequency conversion drive MCU, main control MCU, the first optocoupler and the second optocoupler；The display panel includes panel MCU and panel, and described
Panel for can input display panel, it is described can input display panel include touch key-press and display interface.Wherein：The compressor
It is connected with frequency conversion drive MCU；Frequency conversion drive MCU is connected by first optocoupler with the main control MCU, meanwhile,
Frequency conversion drive MCU is also connected by second optocoupler with the main control MCU；The main control MCU is double with the panel MCU
To connection；The panel MCU is connected with the panel.
On refrigerator after electricity, display panel and frequency conversion electrical control integrated board will carry out two-way real-time communication, positive reason by network
Compressor operating state can be controlled by the touch key-press of display floater under condition, the flow process of signal be touch key-press →
Panel MCU → main control MCU → the first optocoupler → driving MCU → compressor.
When driving MCU to produce fault-signal, MCU is driven to be translated into fault-signal accordingly by the second optocoupler
PWM ripples are sent to main control MCU, then are transferred to the panel MCU of display panel via main control MCU, and panel MCU carries out leading to after data processing
Cross can the display interface of input display panel show.Display a certain signal interval scale can be indicated when display is which
A kind of failure, such as, be then to represent cold room sensor fault when display panel shows E0, different malfunction coefficient letter out
Breath manifestation mode is also different.Refrigerator maintainer just can directly judge event by the unlike signal that display panel shows
The species of barrier and position.
Ultimate principle of the present utility model and main feature are the foregoing described, the description of description simply illustrates this practicality
New principle, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and changes
Enter, these changes and improvements are both fallen within the range of claimed this utility model.
