Description
Technical Field
The invention belongs to the technical field of rapid adjustment of the rotating speed of compressors, and particularly relates to a rapid adjusting device for the rotating speed of a master control frequency conversion integrated plate compressor and an implementation method thereof.
Background
At present, with the implementation of the new national standard energy efficiency standard of the domestic refrigerator, the inverter refrigerator is comprehensively popularized, the inverter refrigerator adopts the inverter compressor, the actual rotating speed range of the compressor is wider, and the operable rotating speed range of the inverter compressor in the industry is generally 1200 plus 4500 rpm.
When the variable frequency compressor is subjected to some conventional tests, such as a cold bench COP performance test and a noise test, the variable frequency compressor needs to be continuously adjusted to different rotating speeds, so that the related performances of the variable frequency compressor and the whole machine at different rotating speeds are tested, and a method for adjusting the rotating speed of the variable frequency compressor is needed during the test. According to the conventional master control/frequency conversion integrated board, the master control part is an MCU, the driving part is an MCU, optical coupling isolation is arranged between the master control and the driving, and meanwhile, master control software controls different frequency signals transmitted to the driving MCU through an optical coupler, so that the driving MCU is correspondingly informed to drive the frequency conversion compressor to operate to different rotating speeds.
Corresponding to this kind of conventional master control/frequency conversion intergral template, owing to there is the master control to give to driven opto-coupler department hardware circuit, when needs constantly adjust the frequency conversion compressor and move to different rotational speeds, general way adopts a signal generator, is connected to the master control through the pencil and gives driven opto-coupler hardware department, through the output frequency of quick adjustment signal generator like this, can give to drive MCU and inform that drive MCU drives the frequency conversion compressor and move few rotational speeds at most.
With the increasing cost requirement of the master control frequency conversion integrated board, the existing master control and drive part adopts a single-chip master control frequency conversion integrated board of one MCU, and for the single-chip master control frequency conversion integrated board, because the master control and the drive are the same chip, a hardware circuit part of an optical coupler between the master control and the drive for transmitting frequency signals is not available, so that a conventional method for adjusting different output frequencies by using a signal generator to control the frequency conversion compressor to operate to different rotating speeds cannot be adopted.
For the master control frequency conversion integrated board of the single chip, when the frequency conversion compressor is required to run to different fixed rotating speeds, the test programs with the fixed rotating speeds of various versions are generally continuously written, and when the rotating speeds are required to be tested, the corresponding test programs with the fixed rotating speeds are correspondingly written into the single chip.
The defects of the prior art are as follows:
because the rotating speed range of the variable frequency compressor of the refrigerator is wider, 1200 plus 4500 turns, when a refrigeration person needs to test the performance under a plurality of rotating speeds, the refrigeration person needs to continuously contact an electric control person to perform software programming updating to correspond to the fixed rotating speed, and the method has low efficiency and poor convenience;
some frequency conversion compressor capability test projects need the frequency conversion compressor supplier to test, and after the main control frequency conversion integrated board posted the supplier, the supplier generally did not have the ability of writing main control frequency conversion integrated board single-chip, so when needing to adjust frequency conversion compressor operation to different rotational speeds, this kind of mode was difficult to implement.
