Taking an air conditioning system as an example, a technology for learning and diagnosing based on actual maintenance conditions needs to collect original data and analyze big data of maintenance and replacement conditions of each part of an air conditioning unit, and for replacement of components without physical address attributes in the air conditioning system, the air conditioning unit cannot know the replacement and cannot automatically acquire the record of maintenance and replacement of the components, which is not beneficial to building and analyzing a database of the big data.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a method for collecting the replacement records of the parts of equipment, which comprises the following steps:
step 1, allocating a unique identifier to a part of equipment;
step 2, regularly receiving and storing the unique identification sent by the parts;
step 3, judging whether the unique identification of the part changes;
and 4, recording that the parts are replaced if the parts are changed.
Preferably, before the step 3 is executed, it is first determined whether the device fails, and if the device fails, the step 2 is returned to; and if the fault occurs, executing the step 3 after the fault is repaired.
Preferably, when the device is judged to have a fault, the fault type is continuously judged, and in step 3, only whether the unique identifier of the part related to the corresponding fault type is changed or not is judged.
Specifically, the device failure may be determined according to a failure occurring within a preset time period for a preset number of times. Likewise, the fault repair of the device may be determined based on the failure not occurring once within a preset time period.
In a specific embodiment, the unique identifier is an identifiable physical address unique to the component. In another embodiment, the unique identifier is a communication address unique to the component.
The invention also protects the air conditioning system which adopts the method of the technical scheme to collect the replacement records of the parts.
In a first embodiment, the components of the air conditioning system include a main control board, driving boards communicating with the main control board, and a moving part driven by the driving boards. And the air conditioning system receives and stores the unique identification sent by each drive board through the main control board, and records whether the drive board is replaced or not according to the change of the unique identification. And after the main control board fails, the corresponding moving part is judged to be replaced according to the fact that the unique identification of the corresponding driving board is unchanged. When the moving part comprises a compressor, the main control board can also judge whether the compressor is replaced or not through a pressure value detected by a sensor for detecting evaporation pressure and/or condensation pressure.
In a second embodiment, the components of the air conditioning system include a main control board, driving boards communicating with the main control board, moving parts driven by the driving boards, and a main board disposed in the moving parts and communicating with the main control board. The air conditioning system receives and stores the unique identification sent by each drive board and each mainboard through the main control board, and records whether the drive boards and the moving parts are replaced or not according to the change of the unique identification.
In a third embodiment, each component of the air conditioning system records a unique communication address of the component and other components, the named component judges whether an unrecorded communication address exists or not, and the component corresponding to the communication address is replaced.
The invention can be used for the main control board to judge whether parts are replaced or not only by adding the unique identification of each part in the communication data when other parts are communicated with the main control board, so that the invention is convenient to realize, but can collect effective maintenance and replacement records for big data analysis and fault diagnosis. Moreover, the invention further provides that the unique communication address is used as the unique identifier, so that when any part is called between all parts including the main control board, whether other parts are replaced or not can be known, and the acquired data is more comprehensive.

Detailed Description
The principles and all embodiments of the present invention are explained in detail below.
The invention distributes a unique identifier for each part of the equipment, then regularly receives and stores the unique identifiers sent by the parts, judges whether the unique identifiers of the parts are changed or not, and records that the parts are replaced if the unique identifiers of the parts are changed.
In a preferred embodiment, whether the equipment has a fault is judged firstly, if the equipment has no fault, the unique identifier sent by the part is continuously received, and the step of judging whether the part is replaced is not carried out. If the fault occurs, after the fault is repaired, whether the unique identifier of the part is changed or not is judged, whether the part is replaced or not is checked, and system resources are saved.
In a further optimized embodiment, if a fault occurs, after the fault is repaired, the type of the fault is judged first, and then only whether the unique identifier of the part related to the corresponding fault type changes is needed to be judged, so that system resources are further saved.
Specifically, the device failure may be determined according to a failure occurring within a preset time period for a preset number of times. The fault repair of the device may be determined based on the failure not occurring once within a preset time period.
Various embodiments of the present invention are described in detail below with reference to an air conditioning system as a specific apparatus.
As shown in fig. 1, in the first embodiment, the components of the air conditioning system include at least 1 main control board, a drive board for 1 compressor, and other basic components constituting the air conditioning system, such as an evaporator, a condenser, and a throttle unit. Each part is provided with a unique and identifiable physical address, and the unique physical address is used as a unique identifier of each part, so that whether the part is replaced or not is judged. The main control board regularly receives data sent by the driving board, wherein the data sent by the driving board comprises a physical address of the driving board, and running data and states of a compressor or a fan.
The specific process for judging whether the compressor or the drive plate thereof is replaced comprises the following steps:
and judging whether the fault type of the air conditioner is an abnormal fault of a driving type. For example, an abnormal failure of the driving class occurs a times in the continuous time t1 of the air conditioning system, which indicates that the abnormal failure of the driving class occurs in the air conditioning system, and the main control board records the abnormal information.
And judging whether the fault of the air conditioning system is repaired or not. For example, if the air conditioning system does not have the driving type abnormal fault for 1 time within the continuous time t2, it indicates that the driving type abnormal fault of the air conditioning system has been repaired, and it is necessary to further determine which components are replaced by a specific maintenance operation.
And judging whether the drive plate is replaced in the maintenance process. The main control board of the air conditioning system judges whether the physical address of the driving board changes or not, if the physical address changes, the driving board of the compressor is replaced in the maintenance process, and if the physical address does not change, the driving board of the compressor is not replaced.
Judging whether the compressor is replaced in the maintenance process; if the fault is repaired, but the driving plate of the compressor is not replaced in the maintenance process, the fact that the compressor is replaced in the maintenance process is indicated.
In addition to the above method, it is also possible to employ a sensor for detecting an evaporation pressure and/or a condensation pressure, and the main control board determines whether the compressor has been replaced according to a pressure value detected by the sensor. For example, after the driving type abnormal fault occurs and before the fault is repaired, if there is a continuous time t3 which is less than or equal to the pressure value P1, the evaporating pressure or (condensing pressure) is used as the basis for judging whether to replace the compressor, wherein the time t3 is less than or equal to the pressure value P1, which indicates that the system is released from the refrigerant and refilled with the refrigerant after being vacuumized in the maintenance process. If the refrigerant is refilled, the compressor is replaced, and if not, the compressor is not replaced.
In addition to the above compressor example, other moving parts such as a fan, etc., and their drive plates may be used in the same manner to determine whether the moving part or its drive plate has been replaced. The replacement records can be recorded by the main control board, and are used as the original data of big data analysis together with the system parameter characteristics before the failure, so as to supplement and update the self-diagnosis database.
As shown in fig. 2, in the second embodiment, the components of the air conditioning system also include a main control board, a driving board of the compressor, and other basic components constituting the air conditioning system, but the compressor is provided with a main board, the main control board can receive data sent by the driving board of the compressor and the main board of the compressor, the sent data includes the driving board of the compressor, the physical address of the main board of the compressor, and the like, and whether the driving board and the compressor are replaced or not is checked by monitoring the change of the physical address.
The specific process for judging whether the compressor or the drive plate thereof is replaced comprises the following steps:
and judging whether the air conditioning system has abnormal driving faults or not. For example, if the air conditioning system has an abnormal failure of the driving class a times within the continuous time t1, it indicates that the air conditioning system has an abnormal failure of the driving class.
And judging whether the fault of the air conditioning system is repaired or not. For example, the air conditioning system continuous time t2 has no abnormal fault of the driving class for 1 time, which indicates that the abnormal fault of the driving class of the air conditioning system has been repaired.
And judging which parts are replaced in the maintenance process. The specific main control board can acquire the physical addresses of other parts, and if the physical addresses of the other parts are changed, the main control board indicates that the part is replaced.
The main control board records the condition of replacing parts in the maintenance process and the system parameter characteristics before failure, and can be used as the original data of big data analysis for supplementing and updating the self-diagnosis database.
As shown in fig. 3, in the third embodiment, the components of the air conditioning system also include a main control board, a driving board of the compressor, the compressor and other basic components constituting the air conditioning system, and the like, and each component adopts a unique communication address as a unique identifier, and uses an address allocated by communication as one of the ways of determining whether a component is replaced. These components can be assigned a unique communication address, for example 01, 02, 03 … …, etc., during a factory test run. After the component is assigned with the communication address, the communication address of the component is recorded, and the communication addresses of the component and other components are recorded. When the parts assigned with the communication addresses do not exist, the communication addresses of the parts which do not exist can be known by the rest parts in the roll call process, and then the parts which do not exist are judged to be one of the main control board, the compressor driving board or the compressor.
The specific process for judging whether the parts are replaced comprises the following steps:
and judging that the air conditioner has abnormal driving faults. For example, if an abnormal failure of the drive class occurs a times within the continuous time t1 of the air conditioning system, it is determined that the drive is abnormal, and the main control board records the abnormal information.
And judging whether the fault of the air conditioning system is repaired or not. For example, the air conditioning system continuous time t2 has no abnormal fault of the driving class for 1 time, which indicates that the abnormal fault of the driving class of the air conditioning system has been repaired.
And judging which parts are replaced in the maintenance process. According to the method, if the communication address corresponding to a certain part disappears in the roll call process and a part without the communication address is added later, the type of the replaced component can be judged according to the method. The replacement of these components can also be obtained and recorded by the main control board. The replacement records of the parts and the system parameter characteristics before the failure can be used as the raw data of big data analysis for supplementing and updating the self-diagnosis database.
Besides the air conditioning system recited in the present invention, other devices can also adopt the above method to determine whether the component is replaced. Besides the listed compressor, fan and driving plate thereof, other moving parts and driving plates thereof, and other non-moving parts in the air conditioning system can adopt the method to collect the replacement records.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
