Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It should be noted that, in the embodiments of the present invention, the term "first \ second" merely distinguishes similar objects and does not represent a specific ordering of the objects, and it should be understood that "first \ second" may be interchanged with a specific order or sequence, where the case allows. It should be understood that "first \ second" distinct objects may be interchanged under appropriate circumstances such that embodiments of the invention described herein may be practiced in sequences other than those illustrated or described herein.

The air conditioning equipment program upgrading method provided by the invention can be applied to the application environment shown in figure 1. The air-conditioning management system may include a server 102, a communication module 104, and an air-conditioning device 106.

The communication module 104 may be directly deployed in a GSM (Global System For Mobile communications, GSM) network, UMTS (Universal Mobile Telecommunications System, UMTS) network, or L TE (L on terminal resolution, L TE) network, and has the characteristics of low power consumption, reliable communication, low cost, and random deployment in any area with or without a public network, the air conditioning equipment 106 may be air conditioning equipment 106 of a single-control or joint-control air conditioner, or may be an air conditioning cluster controller, and the air conditioning equipment 106 may be used to perform upgrade processing and verification processing on the upgrade subfiles transmitted by the communication module 104, and merge the upgrade subfiles with the upgrade subfiles and the verification processing on the upgrade subfiles, and perform communication with the air conditioning equipment 106.

In an actual application scenario, when a program of the air-conditioning equipment 106 is upgraded, the upgrade success rate of the program of the air-conditioning equipment 106 is often reduced due to the situations that the communication quality between the server 102 and the air-conditioning equipment 106 is poor, or data transmission is abnormal due to a large upgrade file, and the like, so that the device program upgrading method in the prior art has the problem of low upgrade success rate.

In one embodiment, as shown in fig. 2, an air conditioner program upgrading method is provided, which is described by taking the method as an example applied to the server 102 in fig. 1, and includes the following steps:

step S210, obtaining an upgrade file.

The upgrade file is a file used to replace an old version of the program file of the air conditioning equipment 106, and the upgrade file may be a code file edited by a computer language and having a logic control instruction, for example, a programming file of a programmer or a single chip microcomputer.

In a specific implementation, before upgrading a program of the air-conditioning equipment 106, a technician first uploads an upgrade file to the server 102, the server 102 analyzes the upgrade file, then sends an upgrade subfile to the communication module 104, the communication module 104 verifies the file, and forwards the file to the air-conditioning equipment 106, so that the air-conditioning equipment 106 merges the upgrade subfile to upgrade the program of the air-conditioning equipment 106.

For example, the air conditioner 106 receives an upgrade file transmitted from a certain terminal by the server 102 before acquiring a program upgrade instruction.

Of course, a person skilled in the art may obtain the upgrade file in other manners, for example, the server 102 may establish a communication connection with other servers, and obtain the upgrade file from other server sides, so that, as can be seen, there may be a variety of manners for obtaining the upgrade file, and the specific manner for obtaining the upgrade file is not limited in the embodiment of the present application.

Step S220, dividing the upgrade file into a plurality of upgrade subfiles according to a preset rule, and acquiring an available communication module connected with the air conditioning equipment.

The upgrading subfile is a subfile obtained by carrying out file type classification processing and data volume division on the upgrading file, and the upgrading subfile has the characteristics of small memory occupation, high transmission speed, flow saving transmission and the like. The communication module 104 is a module for transmitting and checking the upgrade sub-file, the communication module 104 may be an NBIOT module using an NBIOT technology, and the checking mode of the communication module 104 may be crc (cyclic Redundancy check) checking. The available communication module refers to the communication module 104 which is online and can be used for transmitting files in the communication module 104.

In a specific implementation, after the server 102 obtains the upgrade file, the upgrade file is analyzed, that is, the upgrade file is divided into a plurality of upgrade subfiles according to a predetermined rule. Meanwhile, after the server 102 obtains the upgrade file, an available communication module connected to the air conditioner 106 is obtained, where the available communication module is the communication module 104 that is online in the communication module 104 and can provide normal file transmission.

And step S230, acquiring the number of modules and the communication capacity value of the available communication modules, matching the number of the modules and the communication capacity value with the number of files of the upgrading sub-file, and determining a target communication module.

The number of modules refers to the number of available communication modules, for example, 1, 2, and 3. The communication capability value refers to the number of files that can be verified and transmitted by the communication module 104 for the upgrade subfile, for example, if the communication capability value is 3, 2 unit number of upgrade subfiles can be verified and transmitted. The number of files refers to the number of files, for example, 1, 2, 3.

In a specific implementation, after the server 102 obtains the upgrade file and divides the upgrade file to obtain the upgrade subfile, the available communication module is continuously obtained, where the obtaining of the available communication module needs to consider the online state of the communication module 104, that is, the available communication module refers to the communication module 104 that is online and can provide normal file transmission capability. Further, to determine the target communication module, not only the number of files of the upgrade subfile but also the number of modules and the communication capability value of the available communication modules need to be known. Because the communication capability values of the available communication modules may be different, after the server 102 obtains the number of files of the upgrade subfile, the server obtains the available communication module with the communication capability value matched with the communication capability value based on the verification principle that the number of files is satisfied, and the obtained available communication module is used as a target communication module for transmitting and verifying the upgrade subfile.

For example, the number of files of the upgrade subfile is 20, there are currently available communication modules with a module number of 3, and the communication capability values are 7, 5, and 10, respectively, then the target communication module may be an available communication module with a communication capability value of 7, 5, and 10, respectively.

Step S240, sending the upgrade subfile to the air conditioning equipment through the target communication module, so that the air conditioning equipment completes program upgrade.

In a specific implementation, after the server 102 determines the target communication module, the server sends the upgrade subfiles of the corresponding number of files to the target communication module according to the communication capability value of the target communication module, so that the target communication module checks the received upgrade subfiles, and forwards the upgrade subfiles to the air conditioning equipment 106 after checking that the upgrade subfiles are correct, so that the air conditioning equipment 106 further checks the upgrade subfiles and performs program upgrade.

For example, when the number of files of the upgrade subfile obtained by the server 102 is 20, and the target communication module is the communication module 104 with communication capability values of 3, 7, and 10, respectively, 3 of the 20 upgrade subfiles are sent to the target communication module with communication capability value of 3, 7 upgrade subfiles are sent to the target communication module with communication capability value of 7, and 10 upgrade subfiles are sent to the target communication module with communication capability value of 10, so that the upgrade subfiles are sent to the target communication module, and forwarded to the air conditioner 106 by the target communication module.

In the method for upgrading the air conditioning equipment program, the server firstly divides the upgrade file into a plurality of parts by acquiring the upgrade file to obtain an upgrade subfile and acquires an available communication module; then, the number of modules and the communication capacity value of the available communication modules are obtained, so that the number of the modules and the communication capacity value can be matched with the number of the files, and a target communication module is determined; and finally, the upgrading sub-file is sent to the target communication module, so that the target communication module forwards the upgrading sub-file to the air-conditioning equipment, and the air-conditioning equipment utilizes the upgrading sub-file to carry out program upgrading treatment. By adopting the method, the upgrade files are divided, and the matched target communication modules are utilized to respectively transmit the upgrade subfiles, so that the data scale of a transmission bus is reduced, the flow cost is saved, the conditions of abnormal data transmission and the like caused by the larger upgrade files are avoided, and the success rate of upgrading programs of the air-conditioning equipment is improved.

In one embodiment, the step S220 includes:

acquiring the data type of the upgrade file; merging the upgrading files with the same data type to obtain the same type of upgrading files; and according to the data volume of the same type of upgrading file, performing equal data volume division on the same type of upgrading file to obtain a plurality of upgrading sub-files.

The data type refers to the type of data contained in the upgrade file. The same-class upgrading file refers to a file formed by combining a plurality of upgrading files with the same data type. The data size refers to the data size of the file, for example, 10KB, 10M.

In specific implementation, after the server 102 obtains the upgrade file, the upgrade file is analyzed, that is, the upgrade file is classified by using the data type as a standard, the upgrade file is merged according to the data type to obtain a plurality of upgrade files of the same type, and then the upgrade files are divided according to the data amount of the file to obtain a plurality of upgrade subfiles.

For example, the upgrade files include different types of upgrade files such as "data records", "address segment records", that is, the upgrade files of different types are classified and combined to obtain a group of similar upgrade files with a file type of "data records" and another group of similar upgrade files with a file type of "address segment records", and then the similar upgrade files are divided into a plurality of upgrade subfiles with a data size of 500KB based on 500 KB. If the upgrade file acquired by the server 102 is a Hex (16-ary) file, the fourth byte of the Hex file represents a data type, the data type includes "0 x00, 0x01, 0x02, 0x03, 0x04, and 0x 05", where "00" represents a data record, "03" represents a start segment address record, and "05" represents a start linear address record, and the server 102 classifies the upgrade file according to the data type to obtain similar upgrade files of different types. Further, in order to reduce the size of the upgrade file, the server 102 divides each similar upgrade file based on a specific data size to obtain an upgrade subfile with a relatively small data size.

In an embodiment, after obtaining the upgrade files of the same type, the method further includes:

verifying the same kind of upgrading files to obtain a first verification code; the first check code is used for checking the air conditioning equipment, and after the checking is successful, the like upgrading files are combined to obtain the upgrading file and then the program is upgraded; verifying the upgrading sub-file with the same data volume to obtain a second verification code; and the second check code is used for checking the target communication module and for checking the air conditioning equipment after the checking is successful, so that the air conditioning equipment combines the upgrading sub-files after the checking of the upgrading sub-files is successful, and the similar upgrading files are obtained.

In a specific implementation, after the server 102 performs data type division on the upgrade file to obtain the same type of upgrade file, the same type of upgrade file is verified to obtain the first verification code. Then, the server 102 checks the upgrade subfiles obtained by dividing the same data volume of the same type of upgrade files to further obtain the second check codes, and therefore the upgrade subfiles sent by the server 102 to the target communication module include the first check codes and the second check codes. After receiving the upgrade subfile, the target communication module also needs to perform file verification, that is, verify whether the upgrade subfile is correct by using the second verification code, and send the upgrade subfile to the air conditioning equipment 106 when the upgrade subfile is intact. After receiving the upgrade subfile, the air conditioning equipment 106 also uses the second check code to check the upgrade subfile, merges the upgrade subfile after the check result is successful to obtain the same kind of upgrade file, and merges and restores the upgrade file into the upgrade file for program upgrade after continuing to use the first check code to check the same kind of upgrade file successfully.

In one embodiment, the step S230 includes:

acquiring the signal intensity and/or busyness of the available communication module; and determining the communication capacity value according to the signal intensity and/or the busyness.

The signal strength refers to a network signal strength of the communication module 104, and the signal strength determines the communication quality of the communication module 104, that is, the signal strength of the communication module 104 may vary with the network coverage, for example, 1, 3, and 5. The busy level indicates an operation state of the communication module 104, and the busy level of the communication module 104 during operation is higher than that during standby, for example, 2, 4, and 6.

In a specific implementation, after the server 102 obtains the upgrade subfile divided by the upgrade file and the available communication module, the server obtains the communication capability value of the available communication module. The communication capacity value of the available communication module is obtained by obtaining the signal strength and/or the busyness of the available communication module, and the communication capacity value of the available communication module can be obtained by calculating according to the signal strength and/or the busyness of the available communication module.

For example, if the server 102 acquires an available communication module with a signal strength of 3 and a busyness of 5, the communication capability value may be calculated according to the signal strength of 3 and/or the busyness of 5.

In one embodiment, the determining the communication capability value according to the signal strength and/or the busyness includes: calculating the ratio of the signal intensity to the busyness degree to obtain the communication capacity value; or, acquiring a weight ratio of the signal strength to the busyness; calculating the product of the signal intensity and the busyness degree and the weight ratio to obtain a first product value and a second product value; and calculating the sum of the first product value and the second product value to obtain the communication capacity value.

The weight ratio is mathematically given different scale factors in order to show how important a number of numbers have in the total amount. The first product value is a product of the signal strength and a signal strength weight ratio. The second product value is a product value of the busy level and the busy level weight ratio.

In specific implementation, the communication capacity value may be determined by calculating the signal strength and/or busyness, and may be a first calculation method: calculating the ratio of the signal strength to the busyness degree to obtain the communication capacity value, namely, taking the signal strength as a numerator and the busyness degree as a denominator, and calculating the ratio to obtain the communication capacity value; the second calculation method may also be: respectively obtaining a signal strength weight ratio and a busyness weight ratio, calculating the product of the signal strength and the signal strength weight ratio to obtain a first product value, calculating the product of the busyness and the busyness weight ratio to obtain a second product value, and further calculating the sum of the first product value and the second product value to obtain the communication capacity value.

For example, if the signal strength of a certain available communication module is 5, the busyness is 5, the signal strength weight ratio is 0.4, and the busyness weight ratio is 0.6, the first product value is calculated to be 2, the second product value is calculated to be 3, and the communication capability value is 5.

In one embodiment, further comprising:

calculating the sum of the communication capacity values of the available communication modules to obtain a communication capacity sum value a; the matching the module number and the communication capacity value with the file number of the upgrading sub-file to determine a target communication module comprises: determining the number of files of the upgrading subfile as b; comparing the file quantity b with the communication capacity and the value a; and when b is larger than or equal to a, determining the available communication module as the target communication module.

The sum of the communication capability values a refers to the sum of the communication capability values of all available communication modules, for example, 20, 40, and 60.

In the specific implementation, if the sum of the communication capacity values of all the available communication modules cannot meet the number of the upgrade sub-files to be transmitted, all the available communication modules are used as the target communication modules.

For example, if the number of files in the upgrade subfile is 20, the communication capability values of 2 available communication modules are 5 and 7, respectively, and the sum of the communication capability values is 12, all the 2 available communication modules are used as the target communication module.

In one embodiment, the step S230 includes:

when b is less than a, sorting the available communication modules according to the communication capacity value; calculating the sum of the communication capacity values of n available communication modules before sequencing to obtain a capacity value sum c; n is more than or equal to 1; and when c is larger than or equal to b, determining the top n available communication modules in the sequence as the target communication modules.

In the specific implementation, if the sum of the communication capacity values of all the available communication modules can satisfy the number of the upgrade sub-files to be transmitted, the available communication modules can be sorted according to the communication capacity values of the available communication modules, and the sorting rule can be in ascending order or descending order. And after modules are sequenced, calculating the sum of the communication capacity values of n available communication modules before sequencing to obtain a capacity value sum c, and determining the n available communication modules before sequencing to serve as target communication modules when the capacity value sum c is larger than or equal to the number of files.

For example, if the sum of the communication capability values of the 3 available communication modules is 30 and the number of files in the upgrade subfile is 20, the available communication modules are arranged in a descending order according to the communication capability values, and if the communication capability value of the first available communication module in the sequence is 12, the communication capability value of the second available communication module in the sequence is 10, and the communication capability value of the third available communication module in the sequence is 8, the target communication module can be determined as the first available communication module in the sequence and the second available communication module in the sequence.

In one embodiment, the step S240 includes:

In specific implementation, after the target communication module is determined, the upgrading sub-file is sent to the target communication module according to the communication capacity value of the target communication module and the file number of the upgrading sub-file in proportion, and the target communication module sends the received upgrading sub-file to the air conditioning equipment.
