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 conflict in the combined air conditioners unit, is to detect the method whether conflict slave (indoor set) address in the combined air conditioners unit concretely.
Background technology
Have many manufacturers to carry out multi-gang air-conditioner production at present, the application scenario of combined air conditioners unit is also more and more.And because the system of combined air conditioners unit is comparatively huge, indoor set (slave) quantity many (generally reaching 128) in case the address setting of indoor set repeats, the indoor set that repeat the uncontrollable address of off-premises station (main frame) will occur, influences the running and the use of air-conditioning.And present system can only check and report to the police the miscommunication between indoor set and the off-premises station, can't check whether the address of indoor set conflicts.Find the address to repeat the indoor set of (conflict), present method is checked indoor set exactly one by one, the indoor set that finds the address to repeat.Clearly, this method wasting time and energy very, particularly when the indoor set that has a plurality of addresses to repeat, especially need with all indoor sets all traversal check out, expend very big resource.
Summary of the invention
To above problem; The invention provides the detection method of address conflict in a kind of combined air conditioners unit; Automatically indoor set is scanned to judge whether the indoor set of address conflict through off-premises station; When the indoor set of address conflict occurring, can point out fast and accurately, improve the efficient of address conflict inspection.
The detection method of address conflict comprises the indoor units that is connected with off-premises station in the combined air conditioners unit of the present invention, detects step and comprises:
A. off-premises station sends the address scan instruction to each indoor set in the indoor units;
B. off-premises station receives the response data of indoor set feedback, and judges whether said response data is correct, if the judgement response data is an error in data, and execution in step c;
C. off-premises station writes down the address of the indoor set of feedback data mistake, and the address conflict sign is sent to this indoor set;
D. indoor set receives the address conflict sign that off-premises station sends, and is showing accordingly, makes the address of the indoor set of the modified address conflict that operating personnel can be corresponding.
Can scan the indoor set of address conflict fast and accurately through method off-premises station of the present invention; And carry out correspondence and show; Operating personnel through line control machine can this indoor set of direct modification the address; Save the loaded down with trivial details step of hand inspection, improved efficient and convenience that the combined air conditioners unit is installed greatly.
Concrete, whether the response data of judging described in the step b correctly comprises: if the corresponding data of indoor set feedback is always high level or low level, then be communication failure; If the corresponding data of indoor set feedback has the conversion of high-low level, but data content or identifying code mistake then are error in data.
Preferably; In order to guarantee judging whether correctly of off-premises station; The accuracy of improve judging after off-premises station is judged response data first and is error in data, is sent twice address scan instruction to the indoor set of correspondence again and is fed back judgement; If described twice judgement is error in data, then execution in step c.
Preferably, after off-premises station had been judged response data and is error in data, the indoor units that locking is corresponding was forbidden described indoor units start, and indoor units is protected, and improves the fail safe of combined air conditioners unit operation.
The detection method of address conflict in the combined air conditioners unit of the present invention; Can scan to judge whether the indoor set of address conflict indoor set automatically through off-premises station; When the indoor set of address conflict occurring, can carry out corresponding prompting, make operating personnel carry out address modification to corresponding indoor set fast and accurately, save the loaded down with trivial details step of hand inspection; Improved the installation effectiveness and the product quality of combined air conditioners unit greatly, made the combined air conditioners unit intelligent more.
Below in conjunction with embodiment, foregoing of the present invention is remake further detailed description by the accompanying drawing illustrated embodiment.But should this be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following instance.Do not breaking away under 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 flow chart of the detection method of address conflict in the combined air conditioners unit of the present invention.
Embodiment
The detection method of address conflict comprises the indoor units that is connected with off-premises station in the combined air conditioners unit of the present invention as shown in Figure 1, detects step and comprises:
A. off-premises station (main frame) sends the address scan instruction to each indoor set (slave) in the 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, then is communication failure; If the corresponding data of indoor set feedback has the conversion of high-low level, but data content or identifying code mistake then are error in data.Judge whether correctly for what guarantee off-premises station, improve the accuracy of judging, after off-premises station is judged response data first and is error in data; Send twice address scan instruction to the indoor set of correspondence again and feed back judgement; If described twice judgement is error in data, execution in step c, and the corresponding indoor units of off-premises station locking; Forbid described indoor units start, indoor units is protected;
C. off-premises station writes down the address of the indoor set of feedback data mistake, and the address conflict sign is sent to this indoor set;
D. indoor set receives the address conflict sign that off-premises station sends, and the address conflict sign is sent to carry out correspondence on the line control machine and show, makes the operating personnel can be according to the information that shows, the address of the indoor set that conflicts through the corresponding modified address of line control machine.
Can scan the indoor set of address conflict fast and accurately through method off-premises station of the present invention; And carry out correspondence and show; Operating personnel through line control machine can this indoor set of direct modification the address; Save the loaded down with trivial details step of hand inspection, improved efficient and convenience that the combined air conditioners unit is installed greatly.
