Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For convenience of understanding, the embodiment of the present application is described by taking an example of reading an automobile data stream by a diagnostic instrument. It should be understood that it is only one application scenario of the present application, and other application scenarios involving data stream transmission, which are not listed, are also within the scope of the present application.
The automobile data flow refers to data parameters of communication between an ECU (electronic control unit) and sensors and actuators, truly reflects the working voltage and state of each sensor and each actuator, and provides basis for automobile fault diagnosis.
The read data stream is an important function of the diagnostic instrument. The current general flow of reading data streams is: the display process lists the names of all data streams in sequence, a user selects the data stream to be viewed, the display process stores the selection states of all the data streams in an array and transmits the array to the diagnosis process in a shared memory mode. And the diagnosis process reads the information of the data stream with the selected state and displays the final diagnosis result to the user.
However, since each element of the array occupies at least one byte, when the number of the data streams is infinite, the memory occupied by the transfer method is very large, and the memory overflow may occur, which may cause program crash.
In order to solve the problem, an embodiment of the present application provides a data stream interaction method, where a flowchart of the method is shown in fig. 1, and the method includes the following steps:
s10, defining a state array, wherein the state array comprises at least one first element, one first element occupies one byte, one bit represents the selection state of one data stream, and the initial value of each first element represents that the initial selection state of each data stream corresponding to each first element is unselected.
In this embodiment, the number of the first elements in the state array may be determined according to the number of the currently displayed data streams, and since one byte may be split into 8 bits, one first element may represent the selection states of at most 8 data streams. Of course, if the number of data streams is not an integer multiple of 8, a first element, i.e., a byte, is added to characterize the selection state of the excess data stream.
For convenience of understanding, the data streams with sequence numbers 0 to 7 are described below as an example. The selection states of these 8 data streams can be characterized by a first element Arr [0], each bit of Arr [0] representing a selection state of one data stream, a bit having a value of 0, indicating unselected, and a bit having a value of 1, indicating selected. The corresponding relationship between each bit and the data stream may be preset, for example, the data stream with the sequence number of 7 may be set before the data stream with the higher bit, the data stream with the sequence number of 7 may be set by the bit 0, the data stream with the sequence number of 6 may be set by the bit 1, and the data stream with the sequence number of 0 may be set by the bit … …, the bit 7.
Fig. 2 is an example of a first element, which has an initial value of 0, and the corresponding bit values bit 0-bit 7 are all 0, i.e. 00000000.
In practical applications, the process of calculating the number of the first elements in the state array in step S10 "define a state array" may adopt the following steps, and the method flowchart is shown in fig. 3:
s1011, the number of all data streams is acquired.
In this embodiment, all data streams are currently displayed data streams.
S1012, a first ratio of the number of all data streams to 8 and a remainder of the number of all data streams to 8 are calculated.
In this embodiment, assuming that the number of all data streams is a, two variables, i.e., a first ratio b and a remainder c, are defined. The first ratio b is a/8, and the remainder c is a% 8.
S1013, judging whether the remainder is 0 or not; if yes, go to step S1014; if not, go to step S1015.
S1014, the first ratio is used as the number of the first elements in the state array.
And S1015, taking the sum of the first ratio and 1 as the number of the first elements in the state array.
In addition, the process of determining the corresponding relationship between a data stream and a first element in the state array in step S10 "define a state array" may adopt the following steps, and the method flowchart is shown in fig. 4:
s1016, a sequence number of the data stream is acquired.
In this embodiment, a data stream includes information such as a data stream name, a data stream value, and a data stream unit, and a sequence number of the data stream is a number that is assigned to the data stream when the data stream is displayed, and referring to a data stream display interface shown in fig. 5, in order from top to bottom and from left to right, a sequence number of "left-view mirror folding/opening SW" of the data stream is 0, a sequence number of "left front door switch input" of the data stream is 1, and a sequence number of "right front door switch input" of the data stream is 2 … ….
S1017, a second ratio of the sequence number of the data stream to 8 is calculated.
In this embodiment, the corresponding first elements are sequentially determined according to the sequence number of the data stream. Since a byte can be split into 8 bits, the second ratio can be used as the sequence number of the first element in the state array.
And S1018, establishing a corresponding relation between the data stream and the first element corresponding to the second ratio in the state array.
S20, for each first element in the state array, obtaining an actual selection state of each data stream corresponding to the first element, and determining the actual selection state of at least one data stream as a selected target bit.
In this embodiment, the actual selection state of each currently displayed data stream may be determined by responding to a user operation. And one data stream corresponds to one bit in one first element, so that the actual selection state of the data stream corresponding to each bit can be determined, and the actual selection state is selected as the selected target bit.
S30, calling a predefined tag array, wherein the tag array comprises a plurality of second elements, and the value of one second element is used for marking a selected bit in one byte.
In this embodiment, a flag array BYTE ucMask [ ] [ {0x80, 0x40, 0x20, 0x10, 0x08, 0x04, 0x02, 0x01} is defined in advance. Referring to the example of the tag array shown in fig. 6, taking 0x80 as an example, the value of the bits bit 0-bit 7 is 10000000, which is 10000000 when the bit or operation is performed with the first element 00000000, so that it can be determined that the data stream corresponding to the bit 0 is selected. Similarly, if the bit or operation of the first element 00000000 and 0x40 (the value of bit 0-bit 7 is 01000000) results in 01000000, it can be determined that the data stream corresponding to bit 1 is selected; if the first element 00000000 and 0x20 (the value of bit 0-bit 7 is 00100000) bits or operations result in 00100000, it can be determined that the data stream corresponding to bit 2 is selected … ….
In summary, according to the target bit of the first element corresponding to the selected data stream, the second element corresponding to the target bit and the initial value of the first element are selected for bit or operation to calculate the actual value of the first element.
It should be noted that, in the above description of the tag array, the data type of the second element is hexadecimal, and it is understood that other data types, such as binary, octal or decimal, are also within the protection scope of the present embodiment.
And S40, selecting the target second element corresponding to each target bit from the state array, and calculating the actual value of the first element according to the initial value of the first element and the numerical value of each target second element.
In this embodiment, for each first element in the state array, a target second element corresponding to a target bit is determined, for example, the target second element is 0x80 when the target bit is bit 0, and the target second element is 0x40 when the target bit is bit 1, and so on.
And further, combining the bits or operation results of the initial values of the first element and each target second element to determine the actual value of the first element.
For example, the target second elements are 0x80, 0x20, and 0x02, respectively, it can be determined that the bit or operation result of 0x80 and the first element 00000000 is 10000000, the bit or operation result of 0x20 and the first element 000000000000 is 00100000, 0x02 and the bit or operation result of the first element 000000000000 is 00000010, and then the bit or operation can be performed on 10000000, 00100000, and 00000010 again to obtain the actual value 10100010 of the first element.
Of course, the data type of the first element may be any one of binary, octal, decimal and hexadecimal, which is not limited in this embodiment. For example, the actual value of the first element is 10100010 in hexadecimal and 269484048 in decimal.
Of course, in some other embodiments, the step S40 of "calculating the actual value of the first element according to the initial value of the first element and the numerical value of each target second element" may adopt the following steps, and the method flowchart is shown in fig. 7:
s401, the initial value of the first element is used as the current value of the first element.
S402, determining a target second element to be processed, and carrying out bit or operation on the current value of the first element and the numerical value of the target second element to be processed to obtain the intermediate value of the first element.
S403, judging whether an unprocessed target second element exists or not; if yes, go to step S404; if not, go to step S405.
S404, taking the intermediate value of the first element as the current value of the first element, and returning to execute the step S402.
S405, the intermediate value of the first element is used as the actual value of the first element.
For convenience of understanding, the description is continued by taking as examples that the target second elements are 0x80, 0x20, and 0x02, respectively:
the initial value of the first element is 00000000, which is taken for the first time as the current value of the first element. Further, 0x80 is selected as the target second element to be processed, the bit or operation result of 0x80 and 00000000 is 10000000, and then 10000000 is the middle value of the first element and is taken as the current value of the first element. Further, 0x20 is selected as the target second element to be processed, the bit or operation result of 0x20 and 10000000 is 10100000, and then 10100000 is the middle value of the first element and is taken as the current value of the first element. Further, 0x02 is selected as the target second element to be processed, and the bit or operation result of 0x02 and 10100000 is 10100010, since there is no unprocessed target second element at this time, 10100010 is taken as the actual value of the first element.
Of course, it should be noted that when the target second element to be processed is selected, the target second element may be selected randomly, or according to a certain rule, which is not limited in this embodiment.
S50, updating the state array with the actual value of each first element, and outputting the updated state array.
In an application scenario where the diagnostic instrument reads the automobile data stream, the updated state array may be sent to the diagnostic process by the display process, so that the diagnostic process determines the actual selected state as the selected data stream based on the updated state array and the tag array.
Specifically, the diagnostic process may perform bit and operation on the actual value and the marked number group of a first element in the array to obtain the actual selection state of each data stream corresponding to the first element.
Continuing with the example of the actual value of the first element being 10100010, bit-and-operate 10100010 with each second element in the and-state array, assuming that the order of the bit-and-operation is 0x80, 0x40, 0x20, 0x10, 0x08, 0x04, 0x02, 0x01, then:
firstly, 10100010 and 0x80 perform a bit and operation to obtain 10000000, and since the bit 0 of 10000000 is 1, it can be determined that the actual selection state of the data stream corresponding to the bit 0 of the first element is selected;
further, 10100010 and 0x40 perform a bit and operation to obtain 00000000, and since the bit 1 of 00000000 is 0, it can be determined that the actual selection state of the data stream corresponding to the bit 1 of the first element is unselected;
similarly, the bit AND operation of 10100010 and 0x20 can determine that the actual selection state of the data stream corresponding to the bit 2 of the first element is selected; 10100010 and 0x10 may determine that the actual selection status of the data stream corresponding to bit 3 of the first element is unselected; 10100010 and 0x08 may determine that the actual selection status of the data stream corresponding to bit 4 of the first element is unselected; 10100010 and 0x04 may determine that the actual selection status of the data stream corresponding to bit 5 of the first element is unselected; 10100010 and 0x02 may determine that the actual selection state of the data stream corresponding to bit 6 of the first element is selected; 10100010 bit AND with 0x01 may determine that the actual selection state of the data stream corresponding to bit 7 of the first element is unselected.
