For determining product function whether normally it is ensured that product quality is it is necessary to carry out integration test.Integration test process is to allow product to enter
Auto-Sensing Mode runs, and integrated board is automatically opened and closed successively to each load and module or runs by certain rule.By surveying
Examination personnel are observed to loaded work piece situation or test fixture mcu carries out statistics to judge whether to product loaded work piece situation
Qualified.In addition to Auto-Sensing Mode, integrated board also has maintenance mode, in maintenance mode, can only be manually to each load and module work
Selected as state, facilitate designer and tester is directed to certain specific function or module is debugged.Frequency conversion electrical control at present
Integrated board enters Auto-Sensing Mode or maintenance mode needs to utilize display panel, by pinning corresponding to corresponding modes on display panel simultaneously
Two buttons to enter this pattern more than 3 seconds, then selected by display panel button and controlled.This entrance self-inspection and
The method of maintenance mode is comparatively laborious and time-consuming, is unfavorable for that production line is tested, reduces production efficiency, and also may be used in user side
Both patterns can be strayed into due to misoperation, impact user normally uses.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of frequency conversion electrical control test system for refrigerator, works as survey
When examination personnel need detection or maintenance refrigerator frequency conversion system, frequency conversion electrical control test system rapidly enters self-inspection or maintenance mode.
For solving the above problems, the technical solution adopted in the utility model is: for the frequency conversion electrical control test system of refrigerator,
Including frequency conversion electrical control integrated board, display panel, refrigerator load；Described display panel is the display panel with input and output function,
Described frequency conversion electrical control integrated board includes an on-off circuit and a mcu having preset self-inspection and maintenance procedure, described mcu with
Described display panel, the load of refrigerator connect；Described on-off circuit includes power end, resistance and a key switch, wherein,
Power end is connected with one end of resistance, and the other end of resistance is connected with the i/o interface of mcu, one end of key switch, key switch
The other end ground connection.
Further, described key switch is four foot key switches.
Further, the load of described refrigerator includes fan, air door, heater, LED lamp, electromagnetic valve and compressor.
The beneficial effects of the utility model are: this utility model enters self-inspection or maintenance by original by display panel button
The system of pattern is advanced through key switch on integrated board and enters, and simplifies operating procedure, hardware components merely add by
The inexpensive device a little such as key switch, carrys out improving production efficiency in conjunction with software development.Opened by the button of frequency conversion electrical control integrated board
Close, this utility model can quickly select self-inspection or maintenance mode, simplify operating procedure, reduce production hour, improve

Brief description
Fig. 1 is the structural representation of embodiment.
Fig. 2 is the circuit diagram of on-off circuit.
In figure is numbered: vcc is power end, and r is resistance, and k is key switch, and i/o is the i/o interface of mcu.
Specific embodiment
Below by embodiment, this utility model is specifically described.
As shown in figure 1, in embodiment, the frequency conversion electrical control test system for refrigerator includes frequency conversion electrical control integrated board, display
Plate, the load of refrigerator；Wherein, display panel is the display panel with input and output function；The load of refrigerator includes fan, wind
Door, heater, LED lamp, electromagnetic valve and compressor；Frequency conversion electrical control integrated board includes an on-off circuit and a mcu, and
Mcu is connected with the load of display panel, refrigerator.
As shown in Fig. 2 on-off circuit includes power end vcc, resistance r and four foot key switch k, wherein, power supply
End vcc is connected with one end of resistance r, and the other end of resistance r is connected with the i/o interface of mcu, one end of key switch, and button is opened
The other end ground connection closed.The i/o interface of mcu pulls down to ground by four foot key switch k, is pulled upward to mcu by resistance r and powers electricity
Pressure, such as 5v, by the level of the break-make control input i/o interface of four foot key switch k.During four foot key switch connections, i/o connects
Mouth is low level 0v, and when four foot key switches disconnect, i/o interface is high level 5v.Resistance r has current limliting, jamproof effect,
Be conducive to global reliability.
It is preset with self-inspection and maintenance procedure, embodiment utilizes 1 four foot key switch, by self-inspection or maintenance mode in mcu
Corresponding level information directly inputs mcu, and mcu is processed by house software after receiving signal, be directly switch to self-inspection or
Maintenance mode runs.
The operation rule of the present embodiment is: in upper electric 10 seconds, if not carrying out any button operation, enters refrigerator after 10 seconds
Normal operation mode, controls Rules according to refrigerator；Button 1 time in upper electric 10 seconds, automatically into Auto-Sensing Mode after 1.5 seconds,
At once automatically into Auto-Sensing Mode, control Rules according to refrigerator, carry out fan opening and closing successively, air door is opened and closed, heater leaves
Close, LED lamp is opened and closed, electromagnetic valve opening and closing and compressor are opened and closed；Button 1 time in upper electric 10 seconds, button again when interval was less than 1.5 seconds
1 time, be equivalent to even by 2 times, then immediately enter maintenance mode.In concrete production process, typically will not use maintenance mode, only
Just can use under special circumstances, such as designer's debugging debugging.
In practice, those skilled in the art can as needed voluntarily programing operation rule, and be not limited to
Upper operation rule.
Because this utility model carries out model selection by four foot key switches, therefore workman only need to just may be used with a finger
Operated, testing process greatly simplifies.
The foregoing describe ultimate principle of the present utility model and main feature, 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
