Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Embodiment one:
in a specific embodiment, referring to fig. 1, a detection method for a multi-split air conditioner is provided, where the detection method includes:
step S100: detecting and recording the number N of initial indoor units of the multi-split air conditioner;
step S200: detecting and recording the number N' of real-time indoor units of the multi-split air conditioner;
step S300: and detecting whether the indoor units of the multi-connected unit are lost or not according to the initial indoor unit number N and the real-time indoor unit number N'.
Further, detecting and recording an initial indoor unit number N of the multi-split air conditioner, including:
step S110: under the condition of primary power-on of the multi-split air conditioner, continuously detecting the number N of initial indoor units; recording the initial indoor machine number N under the condition that the initial indoor machine number N is kept unchanged in a first time range; and/or
Step S120: under the condition of primary power-on of the multi-split air conditioner, continuously detecting the number N of initial indoor units; and under the condition that the initial indoor machine number N changes within the first time range, continuously detecting the initial indoor machine number N again until the initial indoor machine number N remains unchanged within the first time range, and recording the initial indoor machine number N.
Further, detecting and recording the real-time indoor unit number N' of the multi-split air conditioner includes:
step S210: continuously detecting the number N' of the indoor units in real time; recording the number N 'of the real-time indoor units under the condition that the number N' of the real-time indoor units is kept unchanged in a second time range; and/or
Step S220: continuously detecting the number N' of the indoor units in real time; and under the condition that the number N 'of the real-time indoor units is changed in the second time range, continuously detecting the number N' of the real-time indoor units again until the number N 'of the real-time indoor units is kept unchanged in the second time range, and recording the number N' of the real-time indoor units.
Further, detecting and recording the real-time indoor unit number N' of the multi-split air conditioner includes:
and detecting and recording the number N' of the real-time indoor units of the multi-split air conditioner by identifying the indoor unit communication address of the multi-split air conditioner.
Further, according to the initial indoor unit number N and the real-time indoor unit number N', detecting whether the indoor unit of the multi-split air conditioner is lost, including:
step S310: if the real-time indoor machine number N' is detected to be greater than or equal to the initial indoor machine number N in the third time range, judging that the indoor machine is not lost; and/or
Step S320: if the number N' of the real-time indoor units is detected to be smaller than the initial number N in the third time range, the indoor units are judged to be lost.
In this embodiment, when the primary installation of the multi-split air conditioner is completed and the internal air conditioners are connected, there is an initial number N of indoor air conditioners when the first power-on operation is performed. Because the indoor units of the multi-split indoor unit are not lost when the connection of the indoor units is just completed, the indoor unit number N is recorded as the initial indoor unit number.
When detecting and acquiring the initial number of indoor units, the acquired initial number N of indoor units may be inaccurate due to the just-connected operation. Therefore, in order to obtain an accurate number N of indoor units, it is necessary to maintain uninterrupted detection for a continuous period of time. Specifically, steps S110 and S120 are performed: in step S110, after the multi-split air conditioner is powered on for the first time, if the detected number N of indoor units remains unchanged in the first time period, it is indicated that the detected number of indoor units is stable, and the detected value is set as the initial number N of indoor units; in step S120, in order to obtain an accurate indoor unit number, the indoor unit number needs to be detected again in the first period of time until the detected indoor unit number is no longer changed in the first period of time, and the indoor unit number that is no longer changed at this time can be recorded as the initial indoor unit number N. Wherein the first time is generally set to 3 minutes.
Through steps S110 and S120, the accurate initial indoor unit number N can be obtained, where the initial indoor unit number N is the number of indoor units when the multi-connected unit is initially powered on, and the initial indoor unit number N is obtained as a comparison value for determining whether the number of indoor units of the multi-connected unit is lost, so that the comparison result is more accurate. And if the multi-split air conditioner is installed, the number of indoor units connected is set, and the number N of the indoor units for the first time is detected, so that whether the indoor units are lost after the multi-split air conditioner is installed is also convenient to know.
Further, after the initial indoor unit number N is detected and the initial indoor unit number N is obtained, the real-time indoor unit number N' of the subsequent multi-split air conditioner needs to be continuously detected. After the initial indoor unit number N is obtained, the multi-connected air conditioner can also cause the situation that the internal unit is lost in the subsequent operation process due to various reasons, so that the real-time indoor unit number N' of the multi-connected air conditioner needs to be detected, and whether the internal unit of the multi-connected air conditioner is lost in the subsequent operation process is judged.
Step S210 and step S220 are needed to be performed in detecting the number N' of real-time indoor units of the multi-split air conditioner: in step S210, the number of indoor units connected to the multi-split air conditioner is continuously detected in a certain period of time, and the detection duration time range is set to a second time range, where the second time is generally set to 3min. The purpose is to obtain accurate indoor set values. Therefore, in this step, if the detected number N ' of indoor units remains unchanged within the second time range, the detected number N ' of indoor units at this time is set as the real-time number N ' of indoor units of the multi-split air conditioner. Similarly, if the number of indoor units detected in the second time range changes, the detection needs to be continued again in the second time range until the number of indoor units does not change, and the number of indoor units which do not change any more is recorded as the real-time number of indoor units N' of the multi-connected air conditioner.
Through step S210 and step S220, the real-time number of internal machines N ' can be accurately detected, the real-time number of internal machines N ' is the existing number of internal machines, and whether the indoor unit is lost or not can be finally determined by comparing the real-time number of internal machines N ' with the recorded number of internal machines to be connected.
Furthermore, when detecting the real-time number of indoor units, the indoor unit communication addresses of the multi-connected air conditioner are specifically identified to detect, so that the detection is more accurate and sensitive, and more accurate and sensitive real-time data can be conveniently obtained.
Further, after the real-time indoor unit number N 'and the initial indoor unit number N of the multi-split air conditioner are detected, whether the indoor unit connected with the multi-split air conditioner is lost or not is judged according to the N and the N'. The process mainly comprises steps S310-S320, specifically, when the detected real-time number of indoor units N' is smaller than the initial number of indoor units N, the indoor units are indicated to be lost in the subsequent multi-split air conditioner operation time; when the real-time indoor machine number N' is larger than or equal to the initial indoor machine number N, the fact that the initial indoor machine number is detected indicates that the undetected indoor machines exist, the fact that no indoor machine is lost is indicated, and the fact that the undetected indoor machines on the multi-split air conditioner are detected.
Through steps S310 and S320, whether the indoor units of the multi-split air conditioner are lost or not can be judged, and comparison is carried out within a third time range, so that the judgment is more accurate.
Embodiment two:
in a specific embodiment, the detection method further comprises:
step S400: if the real-time indoor machine number N 'is detected to be larger than the initial indoor machine number N in the third time range, the initial indoor machine number N is updated to be the real-time indoor machine number N'.
Further, after detecting whether the indoor unit of the multi-split air conditioner is lost, the detection method further comprises the following steps:
step S510: judging that the multi-split air conditioner has faults under the condition that the indoor unit is lost, and outputting fault prompt information;
step S520: checking whether the fault is recovered according to the initial indoor machine number N and the real-time indoor machine number N';
step S530: and under the condition of fault recovery, stopping outputting fault prompt information.
In this embodiment, after step S310 is completed, although it is determined that the multi-connected air conditioner is not lost, the detected real-time indoor unit number N' is greater than the initial indoor unit number N, which indicates that the previously undetected indoor unit is detected. At this time, a larger number N of inner machines can be obtained, and the real-time number N 'of indoor machines obtained at this time is set as a new number N'.
The number N of the indoor units is updated, so that the data can be updated in time, the most accurate indoor unit number can be obtained in time, and the subsequent judging process can be facilitated.
Further, after judging whether the indoor unit is lost, continuing to step S510-S530, if the indoor unit is judged to be lost, further judging that the multi-split air conditioner has a fault, and controlling the multi-split air conditioner to prompt fault information. After the fault is displayed, step S520 is performed to continuously detect the number N' of real-time indoor units, and the number is continuously compared with the number N of indoor units, so as to check whether the multi-split air conditioner is recovered or not, and whether the lost indoor units are reconnected or not. If the failure is recovered, step S530 is performed, and in the case of failure recovery, the output of the failure instruction information is stopped.
By performing steps S510-S530, it is achieved that after it is determined that the indoor unit is lost, information indicating a fault can be sent out, and whether the fault has been repaired can be continuously detected and determined. The detection and judgment after the follow-up multi-split fault maintenance are convenient, the use of maintenance personnel is more convenient, and the operation is convenient and efficient.
