Abstract
The invention relates to a detection method for the reliability test of a refrigerator controller. The method comprises the following steps of: inputting analogue signals comprising a system initialization signal, a door control signal, a temperature setting signal and a state detection signal to the refrigerator controller to enable the refrigerator controller to work in different working modes, acquiring state parameters of the refrigerator controller in each working mode, comparing the state parameters with preset values, and judging whether each working mode of the refrigerator controller is normal or not. According to the detection method for the reliability test of the refrigerator controller, the refrigerator controller can be quickly detected in a plurality of working modes, so that detection efficiency is greatly improved; and moreover, the parameters are automatically acquired, so that detection accuracy is improved, and working strength is effectively reduced.
Description
Technical field
The present invention relates to the method that refrigerator detects, is the detection method of refrigerator controller fail-test concretely.
Background technology
When traditional refrigerator controller reliability detects, be to adopt at the indoor laying temperature sensor of refrigeration for refrigerator, judge the working condition of refrigerator controller in testing process by the temperature value of observing sensor.And refrigerator controller is subjected to the restriction of refrigeration characteristic, and the refrigerating speed of refrigerator is slow, and completing all test items needs very long test period.And the rate of change of refrigerator temperature is extremely low in testing process, can not find in time by observing temperature sensor value whether refrigerator controller breaks down, and can not accurately locate trouble location in case break down.Simultaneously this detecting pattern also is difficult to satisfy the refrigerator controller duty is detected in real time.
Summary of the invention
The invention provides a kind of detection method of refrigerator controller fail-test, refrigerator controller is under multiple-working mode detects, and improve the accuracy that detects, reduce working strength.
The detection method of refrigerator controller fail-test of the present invention, by the signal that comprises system initialization, gate control, Temperature Setting and state-detection to refrigerator controller input simulation, refrigerator controller is in different mode of operations, again by gathering the state parameter of refrigerator controller in each mode of operation, described state parameter and preset value are compared, judge whether each mode of operation of refrigerator controller is working properly.The gate circuit that gate control is mainly refrigerator controller provides the analog switch signal.Because the input of various detection signals all simulates out, therefore do not need to wait for long time, refrigerator controller is entered under corresponding mode of operation fast detect.And by detected parameters is gathered contrast, rather than judge by manual observation, improved the accuracy that detects.
Preferably, described Temperature Setting includes the signal that simulates temperature of refrigerating chamber in refrigerator, freezer temperature and defrost temperature.Can make all or part of element circuit work of refrigerator controller by setting different temperature.
Preferably, described state-detection comprises and detects refrigerator controller to the corresponding state of LED lamp, sterilization treasured, compressor control waveform, freezing blower fan, refrigeration air door, defrosting heater, air door well heater and anti-condensation well heater lamp for detecting the duty of refrigerator controller under each mode of operation.
A kind of concrete detection order can for, after system initialization, first sentence the input information whether end has gate control and Temperature Setting, if having process each operational mode state that begins again to detect successively refrigerator controller after corresponding information; If not directly detect successively each operational mode state of refrigerator controller, detect to complete its duty is pointed out, and then jump to and sentence end and have or not the gate control information input section, carry out next step testing.
On this basis, the state parameter of described refrigerator controller in each mode of operation is the data of refrigerator controller output port.
Preferably, gathering the state parameter of refrigerator controller in each mode of operation is by software, each state parameter timing scan to be obtained, and can access thus real-time detection data, is conducive to the staff to timely discovery and the processing of fault.
Preferably, various parameters and information indicating in detection show by display screen, in more intuitive mode, information is pointed out, and display screen can also provide how abundant information.
The detection method of refrigerator controller fail-test of the present invention, refrigerator controller is under multiple-working mode to be detected, significantly improve detection efficiency, and automatically gathered by parameter the accuracy that has improved detection, also effectively reduced simultaneously working strength.
Below in conjunction with the embodiment of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following example.Do not breaking away from the above-mentioned technological thought situation of the present invention, various replacements or change according to ordinary skill knowledge and customary means are made all should comprise within the scope of the invention.
Description of drawings
Fig. 1 is the process flow diagram of the detection method of refrigerator controller fail-test of the present invention.
