Description

Data step compression transmission method and device and electronic equipment for implementing same
Technical Field
The present invention relates to a data processing method and a device and an apparatus for performing the data processing method, and more particularly, to a data compression transmission method and a device and an apparatus for performing the method.
Background
Abbreviation I2The communication method of Inter-Integrated Circuit bus inside the Integrated Circuit of C bus is commonly used because of its easy implementation, but the prior art adopts I2One of the drawbacks of the C-bus communication method is the limitation of data transmission rate. For example, when I is used2When Touch Panel data is transmitted in a C bus communication mode, Touch Panel TP, I is used for short2The rate specified by the C bus communication protocol is 100 kbit/s-400 kbit/s, the report rate of the TP data requires 120 frames/s, and the time for transmitting one frame of TP data is about 8.33 ms. For one frame TP data report, the algorithm occupies about 5ms, the report data is limited to 3ms, and I is used2The communication rate of the C bus is 400kbit/s, the reporting rate is calculated by 120Hz, and the 3ms reported data volume is as follows:
（400000/8/1000）×3 = 150 byte
the data packet of the TP data includes basic data and extension data. The common Touch Data packet with 10 points is used as basic Data, and the extension Data comprises original Data Raw Data used for algorithm expansion, preprocessed Data obtained by subtracting basic Data, or reported gesture track Data. Then in the 150-byte data amount, the Touch packet Package of 10 points already occupies 52 bytes, and the remaining 98 bytes are used as the extension data.
A typical spread data is shown in fig. 1, and includes a 32 × 18 data channel matrix formed by 18 rows and 32 columns of data channels, and the data value of each data channel uses 16-bit binary number, so that fig. 1 needs to pass through I2The expansion data volume transmitted by the C bus is as follows:
（32×18×16）/8 = 1152 byte
it is clear that a typical data size 1152 byte of extension data requires I2The C bus can only transmit for a longer time.
This is a problem that is often encountered with respect to reporting TP data. When this problem occurs, the prior art should increase the length of the data Buffer, meaning the above-mentioned I2The C bus can provide the time for reporting TP data, 8.33ms, less thanIn order to finish reporting TP data, the reporting time needs to be prolonged, but the processing mode in the prior art causes the sudden drop of the report rate, the report rate directly affects the TP operation experience of a user, the higher the report rate is, the smoother the user experiences the TP operation, the experience of the sudden drop of the report rate to the user is that the TP operation smoothness is poor, and even the TP operation has pause and lag. Thus, prior art I2The C bus data transmission has defects of the computing capability of the embedded system, such as precision requirement, poor graph computing capability, small memory and the like, and has no better method for transferring the computing capability, so that the technical extension of the application of a plurality of touch detection fields is limited.

The first embodiment of the present invention, as shown in FIG. 3, sets up the coordinate data of the report point in the data packetBefore the data is expanded. In addition, the fourth embodiment of the present invention, as shown in fig. 9, is different from the first embodiment only in that the point coordinate data is set after the extension data in the packet, which is also a possible solution.

In practice, the device can then generally be used both as a data receiving device and as a data transmitting device. In the process of I2In the two devices for C bus communication, the device serving as a data receiving device is set as a master device of the method of the present invention, and the device serving as a data transmitting device is set as a slave device of the method of the present invention.

That is, the first 16 data channels from left to right in the first row are the zero data channel CH0, the one data channel CH1, … …, and the fifteen data channel CH 15; the second row is sixteen data channels CH16, seventeen data channels CH17, … …, thirty-one data channels CH31 in turn according to the first 16 data channels from left to right, and so on, and the first row is two-hundred eighty-eight data channels CH288, … …, three-hundred-zero data channels CH303 in turn according to the last 16 data channels from left to right; and so on.

For transmission data comprising 32 × 18 data words, the value of each data word is replaced with the threshold interval code of the threshold interval in which the value is located according to the value of the data word, i.e., the threshold interval in which the channel value of the data channel is located, to form interval code data comprising 32 × 18 interval code data words as shown in fig. 2, i.e., the 32 × 18 data words are converted into 32 × 18 binarized interval code data words.
Threshold interval codes of more than two interval code data words are combined into one compressed data word according to a data word compression/decompression protocol. In a first embodiment of the present invention, as shown in FIG. 3, a compressed data word comprises an 8-Bit binary code, Bit0, Bit1, … …, Bit 7. The interval code data words are in one bit binary code, then 8 interval code data words are combined into one compressed data word, so that R = Q/8=72, resulting in 32 × 18 interval code data words being converted into 72 compressed data words, the 72 compressed data words constituting a compressed transmission data frame. Fig. 4 shows 72 compressed data words in a compressed data frame, the data value of each compressed data word being represented in decimal numbers. The data size of the 72 compressed data words is 72 bytes. Therefore, the data volume of the transmission data is compressed from 1152 byte to 72 byte of the data volume of the compressed transmission data frame, and the compression rate is 16 times.
The compression of the interval code data words into compressed data words needs to be performed according to a data word compression/decompression protocol. In the first embodiment of the present invention, as shown in fig. 2 to 4, when data word compression is performed, the rule of selecting interval code data words for compression into a compressed data word is to select a group of interval code data words of 8 data channels for compression into a compressed data word according to the data channel ordering, with each 8 data channels as a group. The ordering of the section code data words compressed into compressed data words is, as shown in fig. 3, that the section code of the data channel with the smallest number among a group of 8 consecutive data channels is set as the lowest order of the compressed data words, and the section code data words of the data channels are sequentially arranged in the order of the compressed data words from the lower order to the higher order in the order of increasing the data channel numbers; that is, the section codes of the data channels CH0 to CH7 are compressed into one compressed data word, the section code of the data channel CH0 is set to zero Bit0 of the compressed data word, the section code of the data channel CH1 is set to one Bit of the compressed data word, Bit1, … …, and the section code of the data channel CH7 is set to seven Bit of the compressed data word, Bit 7. The compressed data words are arranged in the sequence that compressed data words compressed by interval code data words of every 8 data channels are sequentially ordered from small to large as shown in fig. 2 and 4. As shown in fig. 4, the 9 th compressed data word is a compressed data word of the interval code of the first eight data lanes of line 5 shown in fig. 2, and the decimal data value of the 8-bit binary data value 00011000 is 24. The 17 th compressed data word is the compressed data word of the interval code of the first eight data channels in line 9 of fig. 2, and the decimal data value of the 8-bit binary data value 00010001 is 136. When compressing data words, the rules for compressing interval code data words into compressed data words include rules for setting selected interval code data words for combination into a compressed data word, and rules for setting the ordering of the interval code data words for combination into compressed data words. When compressing data words, the rule for composing compressed data words into compressed transmission data frames comprises the arrangement sequence of the compressed data words. The specific content of the above rules should be set reasonably according to the data characteristics, application environment and other factors. In application, all the settings may be set, or only at least one of them may be set.
The slave device sends the compressed transmission data frame to the master device. In the first embodiment of the present invention, the compressed transmission data frame is compressed to less than 98 bytes, so that the transmission of the compressed data frame will not cause the decrease of the reporting rate.
The master device parses the received compressed transport data frame according to the data word compression/decompression protocol, and decomposes the 72 data compressed words back into 576 interval codewords.
The decompression of compressed data words into interval code data words also needs to be performed according to a data word compression/decompression protocol. In a first embodiment of the invention, the rule for decomposing a compressed data frame into compressed data words during decompression of the data words comprises setting the decompression order of the compressed data words, i.e. sequentially decompressing the compressed data words according to their ordering. In a first embodiment of the present invention, the rules for decompressing compressed data words into interval code data words during data word decompression include setting the order of decomposition of compressed data words into interval code data words and setting the order of restoration of the decomposed interval code data words in accordance with the order of compression of data words. Of course, if it is convenient to perform the subsequent processing of the data and the purpose of the data is taken into consideration, the data word decompression rule different from that of the first embodiment may be adopted. In application, all the settings may be set, or only at least one of them may be set.
The invention reserves the characteristic point of the transmission data through threshold quantization, greatly reduces the number of the data value of the data word under the condition of not influencing the requirement of the report rate, ensures that the data volume of the transmission data is compressed by combining a plurality of data words without distortion, has high compression ratio, and improves I2The data transmission efficiency of the C bus effectively solves the problem of the computing transfer capability of the embedded system.
The rules used during compression and the rules applied during decompression in the data word compression/decompression protocol can be associated with each other or have no association, and corresponding compilation needs to be made according to the data characteristics and application scenes.
When the number of the feature points of the transmission data is large, the feature points can be reserved by setting more than one order of threshold values, namely, the value of Z is reasonably increased, and data compression transmission is carried out through more than one data threshold values. As shown in fig. 5 to 7, a set of transmission data different from that shown in fig. 1, which has 4 characteristic points, is required to pass through 4 data thresholds TH1＜TH2＜TH3< TH4 into 5 threshold intervals (-infinity, TH)1]、（TH1，TH2]、（TH2，TH3]、（TH3，TH4]、（TH4And + ∞) and 4-stage compression is performed. The threshold value section codes respectively set for the respective threshold value sections are 0, 1, 2, 3, 4 in decimal, and the decimal threshold value section codes should be converted into binary codes in actual processing. For a set of transmission data different from that shown in fig. 1, the interval code data word formed by the conversion is shown in fig. 5.
Although more characteristic points are reserved through the multi-level data threshold with more than one level, the compression rate of the transmission data is reduced, and in addition, for some transmission data, the compressed data amount is still higher even through the compression of the first-level data threshold with higher compression rate. For the two cases, the method can be realized by a scheme of decomposing the transmitted data and combining and restoring. Based on the method of the present invention, the present invention also provides a process of transmission data decomposition/combination:
before the data processing process is performed on the transmission data,
the slave device decomposes one frame of transmission data into at least G sub-frame transmission data, wherein G is more than or equal to 2; the data processing process is respectively carried out on the transmission data of each subframe, so that the main device obtains G subframe interval code data;

A third embodiment of the present invention, as shown in fig. 8, decomposes transmission data including 32 × 18 data words, which is different from that shown in fig. 1, into transmission data including 16 × 18 data words in 2 subframes, and converts the transmission data into an interval code data word, i.e., the case of G =2 described above. By the method for decomposing/combining the transmission data, the transmission data is ensured to be completely transmitted in the time domain based on the transmission rate and the report point rate.

the section code data including Q section code data words is converted from transmission data including Q data words by:
and setting Z data thresholds, wherein Z is more than or equal to 1, so that Z +1 threshold intervals are formed, and a threshold interval code is respectively set for each threshold interval. And replacing the numerical value of each data word with the threshold interval code of the threshold interval in which the numerical value of the data word is positioned according to the threshold interval in which the numerical value of the data word is positioned, and forming interval code data comprising Q interval code data words.
In order to further improve the data compression amount, the master device can also complete data combination with the slave device. When the slave device decomposes a frame of transmission data into at least G sub-frame transmission data, G is more than or equal to 2, the slave device sends G sub-frame compression transmission data frames to the master device, and then the composition and connection structure of each electronic component of the master device enable the master device to complete the following data combination process:
