The following explains a specific implementation process of the application program updating method provided in the embodiment of the present application based on the above actual working scenario.

Fig. 2 is a first flowchart illustrating an update method of an application according to an embodiment of the present application, please refer to fig. 2, where the method includes:

s210: and receiving an update package of the application program sent by the server-side equipment.

Wherein, the update package includes: the compressed update data is huffman coded.

Optionally, the execution subject of the method may be the above-mentioned working device, and the working device may receive an update package of the application program sent by the server device, where specifically, the reception of the update package of the application program may be implemented based on a wired communication connection manner (for example, a data line).

The update package of the application program may specifically be a data package for updating and upgrading the application program in the working device, and the data package may be compressed update data based on huffman coding.

Optionally, the compressed update data based on huffman coding may be a coding sequence with a preset length, and may specifically be a binary sequence or other types of sequences, which is not limited herein.

The huffman coding may be a coding scheme for replacing a longer data segment frequently appearing in a segment of data with a shorter data segment, and specifically, when applied to this application, may be a coding scheme for replacing a longer coding sequence with a shorter coding sequence, for example: a binary code sequence of 6 bits length is replaced with a binary code sequence of 3 bits length.

The Huffman coding uses a variable length coding table to code a source symbol (such as a letter in a file), wherein the variable length coding table is obtained by a method for evaluating the occurrence probability of the source symbol, letters with high occurrence probability use shorter codes, and conversely letters with low occurrence probability use longer codes, so that the average length and the expected value of a character string after coding are reduced, and the purpose of lossless data compression is achieved.

S220: and carrying out Huffman coding decompression on the updated data based on the target coding mapping table to obtain decompressed data.

The target coding mapping table is used for recording the mapping relation between the compressed data and the decompressed data.

Alternatively, the target encoding mapping table may be a table stored in the memory of the working device in advance, and may specifically be a data dictionary, which is used for characterizing the mapping relationship between the compressed data and the decompressed data.

It should be noted that the working device may perform huffman coding decompression on the update data based on the target coding mapping table, so as to obtain decompressed data, where the decompressed data is the original update data before being compressed.

Optionally, in the process of generating the encoding mapping table, data strings with higher frequency in the data may be extracted according to a certain rule to form a data dictionary; original data are coded according to the data dictionary to obtain coded data so as to achieve the purpose of compression; and restoring the encoded data according to the data dictionary to obtain the original data. That is, the encoding mapping table can be applied to both the compression process and the decompression process.

S230: the application is updated based on the decompressed data.

Optionally, the decompressed data is original update data, and the original update data may be a manner of expanding or adding functions to an application program in the working device to implement the update, or the like. Or directly replacing the original application program, and using the original updating data as the updated application program, thereby realizing the updating of the application program in the working equipment.

The updated data can be decompressed through the target coding mapping table, so that decompressed data can be obtained, and the efficiency in the data transmission process can be improved; and moreover, the mode of Huffman coding decompression is adopted, so that the risk is relatively low, the safety of data transmission can be improved, and data leakage is avoided.

Another specific implementation procedure of the application program update method provided in the embodiment of the present application is explained below.

Fig. 3 is a flowchart illustrating a second method for updating an application according to an embodiment of the present application, referring to fig. 3, where a target code mapping table includes: the compressed sequences are all preset lengths; performing Huffman coding decompression on the updated data based on the target coding mapping table to obtain decompressed data, wherein the method comprises the following steps:

s310: at least one actual sequence having a preset length is sequentially read from the update data.

Optionally, the update data may specifically be a coded sequence with a certain length, and may be read according to the preset length, so as to sequentially obtain a plurality of actual sequences, for example: if the update data is a 300-bit code sequence with a predetermined length of 3 bits, i.e. every 3 bits is used as an actual sequence, 100 actual sequences may be included.

S320: a sequence that is both decompressible and non-decompressible of the at least one actual sequence is determined based on the target encoding map.

Optionally, the target encoding mapping table may specifically include: the compressed sequence comprises at least one compressed sequence and decompressed sequences corresponding to the compressed sequences, wherein the number of bits of the compressed sequences can be equal to the preset length, and the number of bits of the decompressed sequences corresponding to the compressed sequences is the number of bits corresponding to the original updating data.

For example, continuing with the above example as an example, if every 6 bits in the original update data are compressed as a sub-sequence (e.g., 101001), so as to obtain a compressed sequence (e.g., 100) with 3 bits, a mapping relationship between the two sequences may be recorded in the target encoding mapping table, that is, "100" in the compressed sequence indicates "101001" in the decompressed sequence (i.e., the corresponding sequence in the original update data).

Optionally, a plurality of mapping relationships may be recorded in the target coding mapping table, and a plurality of actual sequences may be obtained based on the reading manner of S310.

After the actual sequences are determined in sequence, it may be determined from the target encoding mapping table whether each actual sequence has a corresponding decompressed sequence in the target encoding mapping table, if so, the actual sequence may be determined to be a decompressible sequence, and correspondingly, if not, the actual sequence may be determined to be a non-decompressible sequence.

The specific process may be that, if the first actual sequence is the same as any compressed sequence in the target encoding mapping table, the first actual sequence is determined to be a sequence that can be decompressed; if the first actual sequence is different from each compressed sequence in the target coding mapping table, determining the first actual sequence as an uncompressible sequence; wherein the first actual sequence is any one of the at least one actual sequence.

The target code mapping table can be as shown in the following table 1:

TABLE 1

Compressed sequence	Post-decompression sequence
		100	101001
111	110110
		…	…

As shown in table 1 above, the target encoding mapping table may be a mapping relationship between a plurality of compressed sequences and their corresponding decompressed sequences.

It should be noted that the table 1 shown above is only an example, and the mapping relationship of the target code mapping table may be set according to actual requirements in an actual working process, and is not limited thereto.

S330: decompressing each sequence capable of being decompressed based on the target coding mapping table to obtain an actual decompressed sequence corresponding to each sequence capable of being decompressed, and obtaining decompressed data according to the actual decompressed sequence corresponding to each sequence capable of being decompressed and the non-decompressed sequence.

Optionally, after determining the decompressible sequence and the non-decompressible sequence, the corresponding decompression may be performed on the decompressible data to obtain an actual decompressed sequence, and continuing to take the above example as an example, if the decompressible sequence is "100", the corresponding actual decompressed sequence is "101001".

After each piece of the decompressible data is sequentially decompressed, all actual decompressed sequences can be obtained, and then the decompressed data can be obtained according to the actual decompressed sequences and the non-decompressed sequences.

Next, a further specific implementation procedure of the application program update method provided in the embodiment of the present application will be explained.

Fig. 4 is a third flowchart of a method for updating an application program according to an embodiment of the present application, please refer to fig. 4, where decompressing each sequence based on a target coding mapping table to obtain an actual decompressed sequence corresponding to each sequence, and obtaining decompressed data according to the actual decompressed sequence and an uncompressible sequence corresponding to each sequence, the method includes:

s410: and determining the decompressed sequences corresponding to the decompressed sequences according to the mapping relation between the compressed sequences and the decompressed sequences in the target coding mapping table.

Optionally, the actual decompressed sequence corresponding to each decompressible sequence may be determined in sequence according to the mapping relationship in the target coding mapping table, where the actual decompressed sequence is the decompressed sequence corresponding to each of the above decompressible sequences.

S420: and splicing the non-uncompressible sequence and the decompressed sequence in the updated data to obtain decompressed data.

Optionally, after obtaining the decompressed sequence, all the non-decompressed sequences and the decompressed sequence (actual decompressed sequence) may be spliced according to the original order, and the result obtained by splicing is the decompressed data.

For example, the update data is "100010", where "100" is a sequence that can be decompressed, and "010" is a sequence that cannot be decompressed, then "100" may be decompressed first to obtain "101001", and then "101001" and the sequence that cannot be decompressed "010" are spliced together according to the original sequence, so as to obtain "101001010", which is the decompressed data.

The above-mentioned splicing between two sequences is only taken as an example, in the actual splicing, splicing of a plurality of sequences can be involved, and the splicing principle and process are the same as the above-mentioned process, and are not repeated herein.

The following explains still another specific implementation procedure of the application program update method provided in the embodiment of the present application.

Fig. 5 is a fourth flowchart illustrating an update method of an application according to an embodiment of the present application, referring to fig. 5, an update package further includes: updating the identification information of the coding mapping table corresponding to the data; before performing huffman coding decompression on the updated data based on the target coding mapping table to obtain decompressed data, the method further comprises:

s510: and determining whether the identification information of the coding mapping table corresponding to the updating data is matched with a coding mapping table stored on the working equipment in advance.

Optionally, the identification information of the coding mapping table corresponding to the update data may be specifically used to identify a preset number of bits in the coding mapping table and a corresponding mapping rule, and the like.

After the working device receives the update data, it may be determined whether the identification information of the code mapping table corresponding to the update data matches a code mapping table stored in advance on the working device.

It should be noted that the memory of the working device may include four storage areas, where a first storage area may be used to store the application program, a second storage area may be used to store the update data, and a third storage area and a fourth storage area may be used to store the encoding mapping table, where the third storage area may store the encoding mapping table pre-configured in the working device, that is, the encoding mapping table pre-stored in the working device; the fourth storage area may store an encoding mapping table actually performing the above decoding work.

The memory area can be stored in a flash memory, and the memory is an erasable memory and can be updated and replaced.

Optionally, it may be determined whether the coding mapping table stored in advance on the working device is matched based on the identification information, specifically, it may be determined whether the identification information is consistent with the identification information of the coding mapping table stored in advance on the working device, if so, it may be determined to be matched, and if not, it may be determined to be unmatched.

If yes, S520: and determining the coding mapping table stored in advance on the working equipment as a target coding mapping table.

Alternatively, if matching is determined, the coding mapping table stored in advance on the working device may be determined as the target coding mapping table. That is, the encoding mapping tables stored in the third storage area and the fourth storage area are the same.

If not, S530: and sending an encoding mapping table acquisition request to the server-side equipment.

S540: and receiving a target coding mapping table sent by the server side equipment.

Optionally, if the target coding mapping table is different from the target coding mapping table, the server device may send a coding mapping table obtaining request to the server device, the server device may send the coding mapping table used when compressing the update data to the working device, and after receiving the target coding mapping table, the working device may store the coding mapping table in a fourth storage area to perform corresponding decoding work.

The following explains a specific implementation process of the compression method for providing update data according to the embodiment of the present application based on the above actual working scenario.

Fig. 6 is a first flowchart illustrating a compression method for update data according to an embodiment of the present application, please refer to fig. 6, where the method includes:

s610: and performing Huffman coding compression on the original updating data of the application program based on the target coding mapping table to obtain compressed updating data.

Before the method is executed, the related information of the working equipment can be obtained, and then the target coding mapping table is generated according to the related information of the working equipment.

Optionally, the main execution body of the method may be the server device, and the server device may start to compress the original update data according to an instruction generated by a human operation or a preset instruction for automatic update, and the specific compression manner is similar to the foregoing decompression manner, and may compress the coding sequence with a preset number of bits into a coding sequence with a shorter number of bits according to a preset target coding mapping table.

It should be noted that the decompressed data is also original updated data, and is not limited herein.

In the specific execution process of the method, a corresponding sequence which can be compressed can be found from a target coding mapping table, and the sequence which can be compressed is compressed according to the mapping relation in the coding mapping table, so that the compressed update data is obtained.

It should be noted that, for the convenience of transmission and identification after decompression, the number of bits of the original update data may be set to the number of bits of each compressible sequence or a multiple of the compressible sequence, for example: if the 6 bits are compressed into 3 bits, the bit number of the original update data can be set to be 6 or a multiple of 3, if the bit number is insufficient, the bit can be compensated for the vacant bit, and in the process of decompressing the subsequent working equipment, the data compensated for the bit can be directly deleted.

For example, in the process of generating the target encoding mapping table, the data field division of each 100 bit sequence can be performed on the sequence; extracting a data dictionary from each data domain; converting each data domain and arranging the data domains in sequence according to the difference of the data dictionaries (comparing the data domains with the data dictionaries stored by equipment needing to be upgraded); extracting a difference part of the data dictionary of each data area; according to the steps, several upgrading schemes (namely, a plurality of target coding mapping tables are generated, and one of the target coding mapping tables is selected to be compressed and decompressed when the target coding mapping tables are used) are generated for every 150 bits or 200 bits and the like in the sequence.

S620: and sending the compressed update data to the working equipment so that the application program installed in the working equipment is updated after the working equipment decompresses the compressed update data.

Optionally, after compressing the original update data, the compressed update data may be sent to the working device, so that the working device executes the specific implementation steps of S210 to S230.
