Abstract
The invention relates to a method for detecting address conflicts in multi-connected air-conditioning units, which comprises indoor units connected with outdoor units and includes steps that: a the outdoor units send address scanning instructions to each indoor unit; b the outdoor units receive response data fed back by the indoor units and judge error type of the response data to be data error, and a step c is executed; c the outdoor units send address conflict marks to the indoor units with wrong feedback data; and d the indoor units receive the address conflict marks sent by the outdoor units and perform corresponding display. The method can scan the indoor units through the outdoor units to judge whether the indoor units with the address conflicts exist; and when the indoor units with address conflicts occur, corresponding prompts can be performed. The method enables operators to repair addresses of the corresponding indoor units rapidly and accurately, omits complicated steps of manual inspection, greatly improves installation efficiency and product quality of the multi-connected air-conditioning units, and enables the multi-connected air-conditioning units to be intelligent.
Description
Technical field
The present invention relates to the detection method of address conflicts in multi-connected air-conditioning units, is detect the method for whether conflicting from machine (indoor set) address in multi-variable air conditioning unit concretely.
Background technology
Have many manufacturers to carry out multi-gang air-conditioner production at present, the application scenario of multi-variable air conditioning unit also gets more and more.And due to the system of multi-variable air conditioning unit comparatively huge, indoor set (from machine) quantity many (general nearly 128), once the address of indoor set arranges repetition, just there will be the indoor set that the uncontrollable address of off-premises station (main frame) is repeated, affect running and the use of air-conditioning.And current system can only check the miscommunication between indoor set and off-premises station and report to the police, cannot check whether the address of indoor set conflicts.Find address to repeat the indoor set of (conflict), current method checks one by one to indoor set exactly, finds the indoor set that address is repeated.Clearly, this method wasting time and energy very, particularly when the indoor set having multiple address to repeat, needs all indoor sets all to travel through especially to check out, expend very large resource.
Summary of the invention
For above problem, the invention provides a kind of detection method of address conflicts in multi-connected air-conditioning units, automatically the indoor set judging whether address conflict is scanned to indoor set by off-premises station, can point out fast and accurately when there is the indoor set of address conflict, improving the efficiency that address conflict checks.
The detection method of address conflicts in multi-connected air-conditioning units of the present invention, comprise the indoor units be connected with off-premises station, detecting step comprises:
A. off-premises station sends address scan instruction to each indoor set in indoor units;
B. off-premises station receives the response data of indoor set feedback, and judges that whether described response data is correct, if judge that response data is error in data, performs step c;
C. the address of the indoor set of off-premises station record feedback data mistake, and address conflict mark is sent to this indoor set;
D. indoor set receives the address conflict mark that off-premises station sends, and is showing accordingly, the address of the indoor set of the modified address conflict enabling operating personnel corresponding.
The indoor set of address conflict can be scanned fast and accurately by method off-premises station of the present invention, and carry out correspondence display, operating personnel directly can revise the address of this indoor set by line control machine, eliminate the tedious steps of hand inspection, greatly improve efficiency and the convenience of multi-variable air conditioning unit installation.
Concrete, judge whether response data correctly comprises described in step b: if the corresponding data of indoor set feedback is always high level or low level, be then communication failure; If the corresponding data of indoor set feedback has the conversion of low and high level, but data content or identifying code mistake, be then error in data.
Preferably, in order to ensure off-premises station judge whether correct, improve the accuracy judged, after off-premises station judges that response data is error in data first, send twice address scan instruction to the indoor set of correspondence again to carry out feedback and judge, if twice described judgement is error in data, then perform step c.
Preferably, off-premises station has judged that response data is after error in data, the indoor units that locking is corresponding, forbids described indoor units start, protects, improve the fail safe that multi-variable air conditioning unit runs to indoor units.
The detection method of address conflicts in multi-connected air-conditioning units of the present invention, automatically can scan to indoor set the indoor set judging whether address conflict by off-premises station, corresponding prompting can be carried out when there is the indoor set of address conflict, operating personnel are enable to carry out address amendment to corresponding indoor set fast and accurately, eliminate the tedious steps of hand inspection, greatly improve installation effectiveness and the product quality of multi-variable air conditioning unit, make multi-variable air conditioning unit more intelligent.
Below in conjunction with the embodiment by accompanying drawing illustrated 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 is only limitted to following example.Without departing from the idea case in the present invention described above, the various replacement made according to ordinary skill knowledge and customary means or change, all should comprise within the scope of the invention.
Accompanying drawing explanation
Fig. 1 is the flow chart of the detection method of address conflicts in multi-connected air-conditioning units of the present invention.
Embodiment
The detection method of address conflicts in multi-connected air-conditioning units of the present invention as shown in Figure 1, comprise the indoor units be connected with off-premises station, detecting step comprises:
A. off-premises station (main frame) sends address scan instruction to each indoor set (from machine) in indoor units;
B. off-premises station receives the response data of indoor set feedback, if the corresponding data of indoor set feedback is always high level or low level, is then communication failure; If the corresponding data of indoor set feedback has the conversion of low and high level, but data content or identifying code mistake, be then error in data.In order to ensure off-premises station judge whether correct, improve the accuracy judged, after off-premises station judges that response data is error in data first, send twice address scan instruction to the indoor set of correspondence again to carry out feedback and judge, if twice described judgement is error in data, perform step c, and the indoor units that off-premises station locking is corresponding, forbid described indoor units start, indoor units is protected;
C. the address of the indoor set of off-premises station record feedback data mistake, and address conflict mark is sent to this indoor set;
D. indoor set receives the address conflict mark of off-premises station transmission, address conflict mark is sent on line control machine and carries out correspondence display, enable operating personnel according to the information of display, the address of the indoor set conflicted by the modified address that line control machine is corresponding.
The indoor set of address conflict can be scanned fast and accurately by method off-premises station of the present invention, and carry out correspondence display, operating personnel directly can revise the address of this indoor set by line control machine, eliminate the tedious steps of hand inspection, greatly improve efficiency and the convenience of multi-variable air conditioning unit installation.
