[0002] Power carrier is a technology that uses power lines to transmit information. It uses the power lines themselves as the transmission medium and transmits data to different locations by modulating high-frequency signals.

[0003] A single power carrier communication transmission channel can only transmit one piece of data at a time. When the amount of data to be transmitted is large, it cannot meet the data transmission requirements and easily causes problems such as transmission channel blocking. The data transmission efficiency needs to be improved.

[0004] In the existing data transmission method, if two or more groups of data are transmitted at the same time, there are certain requirements for the relevance of the data, the scope of application is small, and the data analysis speed is slow. At the same time, the transmission process has a great impact on the electric waves in the circuit, which can easily cause the receiving voltage of the electrical appliances to be unstable, causing damage to the electrical appliances.

[0015] Furthermore, the first data and the second data can be expressed by a combination of multiple data in a two-dimensional array;

[0022] The first data slices are all compiled into a standard continuous radio wave according to the A unit distance and the B unit distance to obtain a first radio wave.

[0023] Furthermore, the second control condition is:

BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1 It is a flow chart of the dual-mode communication method described in the present invention. DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figure 1 As shown, the technical solution adopted by the present invention is as follows:

[0047] A dual-mode communication method based on power line carrier communication comprises the following steps:

[0048] The amplitude and waveform of electromagnetic waves are used to carry two sets of uncorrelated data transmission. There is no requirement for the correlation between the two sets of data to be transmitted, and two sets of related data can be transmitted arbitrarily.

[0049] A dictionary is provided at both the data sending end and the data receiving end. The dictionary is a collection of all data, including the basic fields of all transmitted data contents.

[0050] The dictionary is divided into fixed lengths to generate a dictionary array, and each value in the dictionary array is sliced ​​again according to the preset number of bits to obtain a two-dimensional array. The two-dimensional array includes all the data, and any data slice in the dictionary can be retrieved using two values.

[0051] The first data and the second data may be expressed by a combination of multiple data in a two-dimensional array.

[0052] The first data and the second data are sliced ​​according to a preset number of bits to ensure the consistency of all data slices so that the data remains continuous after the transmission is completed.

[0053] The sliced ​​first data and second data are expressed by two-bit characters, wherein the first character is the array sequence number, and the second character is the data sequence number in a single array.

[0054] By selecting the array number and the data number in a single array, you can point to a data slice. Multiple double-bit characters can express the complete data.

[0055] The amplitude of the standard continuous electric wave is determined based on the first data slice, and the first control condition is added to the waveform of the standard continuous electric wave to form a first electric wave.

[0056] The first control condition is:

[0057] Set the A unit distance and the B unit distance, the A unit distance corresponds to the first character of the double-digit character, and the B unit distance corresponds to the second character of the double-digit character. Divide the band of the standard continuous radio wave, and divide it at the apex of each peak and trough of the standard continuous radio wave.

[0058] According to the first data information, the values ​​corresponding to the peak value and the trough value of each band are modified. The values ​​corresponding to the peak value and the trough value are the sum of the A unit distance and the B unit distance. The A unit distance is 10 -m , where m is the length of the dictionary array and the unit distance of B is 10 -n , where n is the sum of the length of the dictionary array and the maximum length of any dimension in the two-dimensional array.

[0059] The value at the beginning of each band is the same as the value at the end of the previous band, ensuring the continuity of the radio waves during data transmission.

[0060] The first data slices are all compiled into a standard continuous radio wave according to the A unit distance and the B unit distance to obtain a first radio wave.

[0061] After the first radio wave is processed, a second control condition is added to the first radio wave, and the second data is carried by the waveform of the first radio wave.

[0062] The second control condition is:

[0063] The second data slice code is read, and the distance between the vertices of each crest and trough in the first radio wave on the X-axis is adjusted so that the distance between the vertices of adjacent crests and troughs corresponds to the sum of the unit distance A and the unit distance B. This operation does not affect the amplitude of the first radio wave, while increasing the processing space of the second data.

[0064] The second data slices are all compiled into the first radio wave according to the combination of the A unit distance and the B unit distance to obtain a continuous radio wave for information transmission.

[0065] After the first data and the second data are added to the standard continuous radio wave, an information transmission continuous radio wave is obtained, and the information transmission continuous radio wave is used to transmit data from the data transmitting end to the data receiving end.

[0066] The data receiving end analyzes the continuous radio waves of information transmission through the first analysis method and the second analysis method. The first analysis method and the second analysis method are performed simultaneously. The efficiency of data analysis is improved, and the system memory is not insufficient due to sequential analysis, thereby improving the fault tolerance of the system.

[0067] The first data is obtained by analyzing the continuous radio waves of the information transmitted by the carrier communication according to the first analysis method.

[0068] The first parsing method is:

[0069] The band of the continuous electric wave of information transmission is divided, and the segmentation is performed at the apex of each crest and trough of the continuous electric wave of information transmission. The segmentation here can be performed using the value of the derivative of the continuous electric wave of information transmission. When the value of the derivative of the continuous electric wave of information transmission is 0, the continuous electric wave of information transmission is a crest point or a trough point, and there is no case of no derivative in the continuous electric wave of information transmission. By segmenting the crests and troughs, the specific value of the first data can be directly extracted without the need for subsequent complex data extraction operations.

[0070] Each band is time-stamped, and the beginning value, end value and time attribute of each band are read. Time stamping can keep the continuity of data unchanged and maintain the sequence of original data.

[0071] Fill the information of each band into the linked list according to the time attribute. The linked list data structure selected here can ensure the continuity of the data. The linked list can effectively avoid errors in the data splicing process due to its special directionality.

[0072] After the current data receiving end receives the information transmission completion instruction, the linked list is extracted. The information transmission completion instruction can be set by the user, such as continuous specific data, or a special password.

[0073] Extract the previous data in each linked list except the last linked list, extract all the data in the last linked list, and obtain the first data code after the transmission is completed. Because except for the last linked list, the next data of the previous linked list is the same as the previous data of the next linked list, if the same data is written repeatedly, the original data will be distorted.

[0074] According to each combination of the A unit distance value and the B unit distance value, the first data encoding data is converted into corresponding slice data in the two-dimensional array to obtain the first data after transmission.

[0075] The data receiving end analyzes the information transmission continuous radio wave transmitted by the carrier communication according to the second analysis method to obtain the second data.

[0076] The second parsing method is:

[0077] After the current data receiving end receives the information transmission completion instruction, the band of the continuous radio wave of the information transmission is divided, and the segmentation is performed at the vertices of each peak and trough of the continuous radio wave of the information transmission. The segmentation method here is the same as the segmentation method in the first analysis method, which reduces the repeated segmentation of the continuous radio wave of the information transmission and avoids the problem of memory overflow.

[0078] Each band is time-stamped and the wavelength of each band is read.

[0079] Fill in the blank list with the wavelength information of each band according to the time attribute.

[0080] After the current data receiving end receives the information transmission completion instruction, the list is extracted. The information transmission completion instruction here is the same as the information transmission completion instruction in the first parsing method.

[0081] Each element in the list is a combination of an A unit distance value and a B unit distance value. The elements in the list are extracted according to the combination of A unit distance and B unit distance to obtain A unit distance value and B unit distance value. The A unit distance value and B unit distance value are converted into corresponding slice data in a two-dimensional array to obtain the second data after transmission.

[0082] It should be noted that in the present invention, the data receiving end processes the first parsing method and the second parsing method synchronously, and there is no need to run the first parsing method before executing the second parsing method, which greatly improves the data parsing efficiency.

[0083] The elements in the list are concatenated into a string in order to obtain a binary code of the second data, and the binary code of the second data is compiled to obtain the second data after transmission.

[0084] When the user data transmission is nearly completed and only a single data is left, the amplitude of the standard continuous radio wave is controlled only according to the first control condition, and after the transmission is completed, the information transmission continuous radio wave transmitted by the carrier communication is analyzed according to the first analysis method to obtain the first data. Adding abnormal state judgment avoids problems such as system process lockup and ensures the applicability of the system.

[0085] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
