The invention is described in detail below with reference to examples and figures, in which:
FIG. 1 is a flow chart of one embodiment of the present invention.
Detailed Description
The principles and embodiments of the present invention are described in detail below with reference to the accompanying drawings.
With the development of the living standard of people, the air conditioner becomes a necessary household device for daily life of people, and therefore, the invention will be described by taking the air conditioner as an example. Besides the wireless communication technology, the existing NB-IOT technology has a huge application prospect as a new technology in the field of Internet of things. This technique has four significant advantages: firstly, the signal coverage is wide; secondly, the method has massive connection capacity; thirdly, the power consumption is extremely low, fourthly, the module cost is low, the characteristics enable the air conditioner to have a wide market, the air conditioner is used as an indispensable household appliance product in modern life, the air conditioner is reasonably combined with the NB-IOT technology, the defects of the existing air conditioner communication technology can be avoided, and the air conditioner is an important branch of future communication technology development, so the application significance is great, and the prospect is promising. The present invention will be described with respect to a case where an air conditioner transmits data to a background remote server using NB-IOT technology.
As shown in fig. 1, the present invention first identifies the device type, obtains the device type by verifying the identification codes of the core components of the device, compares the identification codes of any two core components of the device, obtains the device type according to the identification code if the identification codes are consistent, and sends the device type to a third party for updating. If the identification codes are inconsistent, comparing the identification code of any core component of the equipment with the identification code stored by the third party, and if the identification codes are consistent, acquiring the equipment type according to the identification code; and if the identification codes are not consistent with the identification codes stored by the third party, acquiring the equipment type. In other embodiments, the device type may also be obtained by directly comparing the identification code of any core component of the device with the identification code stored by a third party. Taking an air conditioner as an example, the core components of the air conditioner are a main board and a display board, the display board and the main board can be provided with own bar codes as identification codes when leaving a factory, and an NB-IOT module of the air conditioner can obtain three bar codes when being electrified again each time: the display panel bar code, the mainboard bar code and the local bar code stored by the remote server are consistent when each unit leaves a factory, and when the display panel or the mainboard is replaced, the three bar codes are inconsistent, and at the moment, the NB-IOT module needs to judge and identify the bar codes of the units at first. The NB-IOT module firstly compares the bar code of the display panel with the bar code of the mainboard, when the bar code of the display panel and the bar code of the mainboard are the same, the bar code is determined to be the correct bar code, the bar code is synchronously updated to the local bar code stored in the remote server, if the NB-IOT module identifies that the bar code of the display panel is different from the bar code of the mainboard, the two bar codes are compared with the local bar code stored in the background server respectively, any one of the two bar codes (the display panel and the mainboard) is consistent with the bar code stored in the remote server, the bar code is used as the bar code of the local machine, and if the two bar codes are different from the local bar code stored in the remote server (namely, the three bar codes are different), the local. When comparing bar codes of the display panel and the mainboard, the NB-IOT module stops working and does not send data when the bar codes possibly obtained are not in the range of the planned model, and the correct bar codes are obtained after power failure and restart. Specifically, the finally obtained barcode is compared with a preset barcode, and if the finally obtained barcode is consistent with the preset barcode, the finally obtained barcode is indicated to be in the planning range, and if the finally obtained barcode is inconsistent with the preset barcode, the finally obtained barcode is indicated to be not in the planning range. For example, the air conditioner is divided into a commercial air conditioner and a household air conditioner, the bar code types of the commercial air conditioner and the household air conditioner are different necessarily, if a customer uses the commercial air conditioner at the moment, a unit fails to replace and uses a display panel and a mainboard of the household air conditioner of the same manufacturer, or the customer replaces and uses the display panel and the mainboard of the air conditioner of other manufacturers, the obtained unit bar code is not necessarily in the range of the model planned by the manufacturer, so that under the condition, the NB-IOT module stops working and does not send data, the operation of the NB-IOT module can be stopped under the condition that the unit uses the core equipment by mistake, the invalid data processing of the subsequent steps is reduced, and meanwhile, a way for distinguishing the errors (core equipment replacement errors) is provided for after sale and maintenance.
After the unit bar code of the air conditioner is obtained, the type of the air conditioner is judged, and the air conditioner belongs to one of a large unit, a small unit or a special machine, wherein the large unit specifically refers to an air conditioner with the unit refrigerating capacity of more than or equal to 100kw, the small unit refers to an air conditioner with the unit refrigerating capacity of less than 100kw, and the special machine refers to an air conditioner applied to a special occasion, such as an air conditioner applied to a nuclear power plant or a scientific ship, and each unit type has different data volume due to different load quantity and control modes.
After the NB-IOT module of the air conditioner obtains the classified unit types, the communication data of the air conditioner can be screened and screened according to the unit types. The specific discrimination of the communication data can be to classify the operation data needing communication into parameters such as fault parameters, protection parameters, real-time monitoring parameters and the like according to the operation characteristics of the air conditioner.
The NB-IOT module will then screen the parameters for the last good class. Specifically, the core parameter type of the device can be obtained through experimental data, and then data corresponding to the core parameter type of the device is found during screening, or the core parameter type and the data corresponding to the core parameter type at the current moment are obtained through the operation rule of the monitoring device, and the data are found out to be used as communication data. Or the threshold value of each parameter can be calculated according to specific parameters, and the communication data exceeding the threshold value range is removed in the subsequent processing. For example, the real-time monitoring type parameters comprise a parameter 1 and a parameter 2, and when the range of the parameter 1 transmitted by the air conditioner received by the NB-IOT module exceeds the range of the parameter of the machine type, the NB-IOT module clears the parameter, so that the value of the parameter maintains the effective value transmitted last time.
After the above screening and screening, the communication data is further simplified, the communication burden is reduced, and then the NB-IOT module sends the processed communication data to a third party, which can send the processed communication data according to one of real-time sending, sending according to a set time interval, and sending when a preset data volume threshold is reached. For example, parameters with high real-time requirements in the communication data may be transmitted in real time. Parameters with low real-time requirements in communication data are sent according to a set time interval or a mode of reaching a certain data volume, for example, the parameters are sent once in 1 hour, sent once when reaching 1MB, and sent once when meeting the conditions simultaneously.
The invention processes the communication data in the early stage on the basis of using the NB-IOT communication technology for the air conditioner, can effectively improve the reliability of communication and saves the communication cost. Besides air conditioners, other devices such as refrigerators and televisions are also applicable to the technical scheme of the invention.
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.
