Description of drawings
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model comprises master chip processing module, power module, temperature collect module and display module, and described master chip processing module is gathered the data of frequency-variable air conditioner outdoor machine by cable and frequency conversion off-premises station communication module; Described power module is imported power supply one tunnel with 220V and is exported the off-premises station power interface to, and another road is connected to the power input of master chip processing module after the transformation rectification; Described temperature collect module is JA(junction ambient) temperature sensor and interior machine air outlet temperature sensor and export the master chip processing module to respectively; Described display module is provided with 8 groups of 3 charactrons, and described charactron is connected with the data output interface of master chip processing module respectively, is used for the display process result data; Be provided with voltage, electric current, compressor frequency and some temperature comparators in the master chip processing module, temperature comparator is according to the mode of operation of off-premises station and the temperature value design temperature scope of environment temperature sensor, temperature comparator receives the temperature signal of frequency-variable air conditioner outdoor machine respectively, when voltage, electric current, frequency or the temperature detection data of off-premises station exceeded the setting range of respective comparator, the master chip processing module was sent alerting signal and is controlled corresponding charactron flicker.
Wherein, temperature comparator comprises air outlet temperature, delivery temperature, outdoor coil pipe used temperature and outdoor environment temperature.
The utility model is by 24 charactrons and two sensors and control module gathers the operational factor of off-premises station by telecommunication circuit and an operational mode and a service data that collects of the tested off-premises station of control shows on 8 groups of three charactrons, when the data of every group of charactron are in normal range, data normally show, when data not in normal range, then flicker once comes reminder-data undesired in the every 1s of data.The normal range of data can be regulated automatically according to the temperature in the sensing chamber, to setting the data area of selecting corresponding type automatically by type with different types.
The utility model device directly gives tested frequency conversion outer machine power supply, after the pick-up unit power supply, power switch on the opening detecting device, outer machine powers on, pick-up unit sends out inspection heating mode signal comprehensive for tested outer machine, and outer machine moves with heating mode after receiving signal, and the communication light on the pick-up unit normally glimmers, corresponding heating mode lamp is bright, according to the Frequency point stable operation of different type frequency stabilizations in correspondence.If there is the deficiency on the ability in machine, value corresponding does not just reach stable interval; If there is fault in loom, then show corresponding failure code, by the other failure code table of frock, accurately fault location circuit position.When heating normal operation, after the data stabilization, be converted to refrigeration mode by the mode switching key on the pick-up unit, device is sent out comprehensive inspection refrigeration mode sign indicating number, and corresponding communication light normally glimmers, and the refrigeration mode lamp is bright.After the outer machine of tested frequency conversion receives the refrigeration mode sign indicating number, in order to save detection time, the direct power down of four-way valve, change into refrigeration mode, the compressor 10Hz that rises on the basis of original frequency is in this Frequency point stable operation, if refrigeration is undesired, same data can not reach normal data interval, indication fault.After all data reach in the stable region, pick-up unit sends out the maximum capacity refrigeration mode for automatically detected outer machine, outer machine continues raising frequency to maximum frequency and moves, after reaching maximum frequency, all data are all in normal interval, frock sends out the inspection refrigeration mode comprehensive for once more outer machine, and compressor mixes down to original Frequency point operation, and whole testing process is finished.
The utility model compared with prior art has following remarkable advantage and beneficial effect: can be automatically according to the operation of air conditioner environment temperature, and intelligence is regulated the normal interval of data, improves the detection accuracy and the versatility in season; At first can according to air outlet temperature and exhaust and coil temperature judges whether to lack liquid, system jams and four-way valve does not commutate and temperature sensor wrong whether, secondly, by the current value that shows and magnitude of voltage can determination module operation conditions and the quality of testing circuit, stopped to cause the damage of machine because the bad protection that causes of testing circuit is lost efficacy; Once more the demonstration by failure code we can search 24 kinds of outer machine faults (all faults that comprised outer machine) accurately, accomplished the accurate location of fault, solve the above-mentioned problem that breaks down and can't all locate; In testing process, comprised air-conditioning refrigeration, heat and the high frequency operational mode, noise quality when also having guaranteed simultaneously the high frequency service ability of convertible frequency air-conditioner and high frequency operation has been guaranteed the performance and the quality of the outer machine of whole frequency conversion.
