Below in conjunction with accompanying drawing, the detection system according to the refrigerator of the utility model embodiment is described.
Fig. 1 is the structured flowchart of the detection system of refrigerator according to the utility model embodiment.As shown in Figure 1, according to the detection system of the refrigerator of the utility model embodiment, comprising: the master control borad 110 of refrigerator, detection chip 120 and external test facility 130.
Wherein, master control borad 110 has aobvious control board communications interface 111, refrigerator is connected with aobvious control plate (not shown) by aobvious control board communications interface 111 when normal work, and refrigerator is connected with external test facility 130 by aobvious control board communications interface 111 when detecting.Detection chip 120 is arranged on master control borad 110.Detection chip 120 controls, to detect electrical part electrical part corresponding in refrigerator for the test patterns sent according to external test facility 130.External test facility 130 is connected with aobvious control board communications interface 111, for sending test patterns to detection chip 120.
According to the detection system of the refrigerator of the utility model embodiment, test patterns each electrical part to refrigerator that detection chip can send according to external test facility detects, there is the advantage that test speed is fast, measuring accuracy is high, malfunction elimination can be carried out in time, exactly, all sidedly to refrigerator, save the malfunction elimination time, to save time, laborsaving.
Shown in composition graphs 1, in an embodiment of the present utility model, external test facility 130 comprises: proving installation 131 and interface switching device 132.Wherein, proving installation 131 has first interface.Interface switching device 132 is for being converted to the second interface mated with aobvious control board communications interface 111 by first interface.As shown in Figures 2 and 3, as a concrete example, first interface is RS232 interface, and the second interface is TTL interface.
Composition graphs 1 to Fig. 3, as a concrete example, test process is as follows:
The first interface connecting test device 131 of interface switching device 132 (namely RS232 turns TTL device), wherein, proving installation 131 is such as PC or handheld terminal.For PC, then first interface connects the COM port or COM device or COM1 (general PC carries this interface) of PC, second interface (as RXD with TXD) of interface switching device 132 is connected the aobvious control board communications interface 111 (i.e. RXD and TXD) of master control borad 110, VCC with GND of interface switching device 132 is connected VCC and GND of master control borad 110.
Connection complete ready after, when needing test to detect the electrical part performance of refrigerator (electrical part includes but not limited to: compressor, blower fan, well heater, air door, lamp and motorized valve etc.), test patterns is sent by serial ports by PC, as: 32H 55H32H 31H 31H 4FH 34H.The data of this test patterns are 16 hex value data, are described below to data, such as:
Frame head: 32H 55H 32H.
Address: be fixed as 31H.
Channel number: 31H-represents control compressor, and 32H-represents control heater, 33H indication lamp (as reefer lamp), and 34H represents blower fan (as temperature-changing chamber blower fan), 35H represents temperature sensor.
Command code: ' O', i.e. 4FH, represent that passage is opened.
' C', i.e. 43H, represent pathway closure.
End code: 34H.
After master control borad 110 receives the test patterns of PC, master control borad 110 proceeds to reception instruction mode, controls compressor and opens and control compressor operating, when a unlatching passage, can close every other passage.When under instruction mode, master control borad 110 does not run at the normal operation mode pressing refrigerator, and only have when from after newly powering on or exceed setting-up time, master control borad 110 is just jumped out instruction mode and entered normal operation mode.Wherein, master control borad 110 has instruction mode and normal operation mode, and refrigerator master control borad 110 when normal work is operated in normal operation mode, and refrigerator master control borad 110 when detecting is operated in instruction mode.
In another example of the present utility model, for handheld terminal, owing to not necessarily having PC at the scene, and PC is usually irremovable, and now join a handheld terminal, the test philosophy of its test philosophy and PC is similar, in order to reduce redundancy, does not repeat herein.
Shown in composition graphs 3, handheld terminal should have following functions: can display channel number, band keypress function, have editting function, on turn down function, and generating function.First master control borad 110 is connected by the CON1 of handheld terminal.After connecting connecting line, show 7 short in size acquiescences and be shown as 31, when needs adjustment numerical value is 32, first by [editor], by on turn over [∧] button adjustment numerical value, carry out switch when pressing [ON/OFF] button after display 32 again, then press [generation] button, then hand-held set occurs as issued orders: 32H 55H 32H 31H 32H 4FH 34H.
Frame head: 32H 55H 32H.
Address: be fixed as 31H.
Channel number: 31H-represents control compressor, and 32H-represents control heater, 33H indication lamp (as reefer lamp), and 34H represents blower fan (as temperature-changing chamber blower fan), 35H represents temperature sensor.
Command code: ' O', i.e. 4FH, represent that passage is opened.
' C', i.e. 43H, represent pathway closure.
End code: 34H.
Channel number is exactly the numerical value of 7 segment encode displays.
According to the detection system of the refrigerator of the utility model embodiment, there is the advantage that test speed is fast, measuring accuracy is high, malfunction elimination can be carried out to refrigerator in time, exactly, all sidedly, save the malfunction elimination time, to save time, laborsaving.
In the description of this instructions, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, identical embodiment or example are not necessarily referred to the schematic representation of above-mentioned term.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
