In order to explain the technical solution of the present invention, the following description is made by way of specific examples, which only show the relevant portions of the embodiments of the present invention.

The first embodiment is as follows:

as shown in fig. 1, the present invention provides an automatic compiling method, which includes the following steps: s100: the controller is connected with the upper computer, and automatically generates a programming template file on the upper computer, for example, a 'programming template, TXT' text file is generated as the programming template file, and a user can input a corresponding control code in the programming template file. S200: the user writes the control code in the programming template file, and the control code can adopt the key words of the common programming language so as to reduce the learning cost of the user. S300: the user finishes the compiling of the control code and stores the control code file, if the 'compiling code and TXT' text file is generated as the control code file, the controller automatically compiles the control code file to generate the execution code, a compiling tool on an upper computer is not needed, the automatic compiling reduces the operation difficulty of the equipment, the automatic control equipment can be controlled after the execution code is generated, the execution code does not need to be downloaded to a control terminal, and the operation is quicker and simpler. The invention realizes programming and compiling through the controller, can realize the programming and compiling operation of the user on the equipment without a programming tool and a compiling tool, saves an execution code downloading process, has simpler and more convenient operation process, can finish all operations in a very short time without any programming-based user, and reduces the operation and maintenance cost of the automatic control equipment.

In the control code compiling of the method, the special symbols are defined and respectively comprise the following steps: (ii) the program flags a character, the program starts with "#", and with "#"; "end". No more than 100 characters per line beginning with "#". ② [; annotating a caption or ending statement, the semicolon must be an English punctuation mark, and each line of statement must be in; "end" is used as a flag. (iii) parallel sentence marks, which are equivalent to logical and, comma must be an english punctuation mark. And r represents a condition or a statement flag, which corresponds to a logical or. Assigning or judging mark, inputting as judging, outputting as assigning, left as keyword, right as number, left and right ends without other characters, including blank space. And C, matching X/Y input and output ports.

Input port symbols and output port symbols of the present invention illustrate: input port symbols: x? (. The "underlined" + "X" + numerals "0 to 7" represent input ports. The underline may be preceded by a user-defined designation, e.g., input port 1(X0) may be represented as: x0 or add the user description StartButton X0. "X0 ═ 1" indicates that it is judged whether or not the [ X0] port is high (i.e., X0 indicates whether or not the LED lamp is on). Output port symbol: y? (. The "+" Y "+ numerals" 0-7 "are underlined and represent output ports. The underlining may be preceded by a user-defined designation, e.g., output port 1(Y0) may be expressed as: y0 or add a user description PassLED _ Y0. Y0 ═ 1 indicates that [ Y0] output port Y0_ C is connected to Y0_ NO port in a closed state (while Y0 indicates that the LED lamp is on).

The keywords defined by the invention are respectively as follows: DELAY: a delay statement in milliseconds. # DELAY 1000; representing a delay of 1000 milliseconds. A single delay statement cannot exceed 9999 milliseconds. ② IF: the conditional judgment statement is equivalent to the Chinese 'if'. # IF startbuton _ X0 ═ 0; this indicates whether or not the input signal at the [ X0] port is in the off state of the LED corresponding to X0. If the condition is satisfied, the next statement is executed, and if the condition is not satisfied, the statement after ELSE or ENDIF is jumped to. ③ ELSE: IF and ENDIF are matched for use, which is equivalent to Chinese 'else'. IF the condition of the IF statement is not met, a jump is made to the statement following ELSE. ENDIF: paired with IF statements. Indicating that the current IF statement is finished. WHILE: unconditional loop statements, loop start. Generally, the method circularly uses (ENDWHILE): when the loop is matched with WHILE, the end point of the loop is indicated, and the next loop jumps to a WHILE statement. Seventhly, WHLIF: conditional loop statements, assembly of WHILE IF. Judging the condition, and executing the loop statement if the condition is satisfied. Jump to ENDWHLIF if the condition is not met and then execute the statement. Eighty percent (ENDWHLIF): when the method is used with WHLIF, the end point of the loop is shown, and the next loop jumps to a WHLIF statement. As shown in fig. 3, is an example of programming by the programming template file of the present invention.

As an optional embodiment, the programming template file is in a txt format or a C format, so that the applicability of the method is improved. The txt format is a universal text document format, has good universality, can be opened in most upper computer equipment, is convenient to program through a programming template file, and has simple format and better applicability. The format of C is a C source file, so that professional software technicians familiar with C can program according to the writing habit of C, and the use experience of the part of users can be satisfied.

As an alternative embodiment, as shown in fig. 2, in step S300, the process of the controller performing automatic compilation on the control code file includes the following steps. S310: the controller reads the control code file, detects whether the control code has a grammar error, if so, executes S320, otherwise, executes S330; s320: the controller generates a compiling error report and prompts the compiling error report, and a user checks the compiling error report, modifies the control code file and returns to execute S310; s330: the controller analyzes the control code file line by line and converts the control code file into a two-dimensional array; s340: and the controller compiles the binary array according to a preset format to obtain an execution code.

After the controller reads the control code file, the grammar is analyzed line by line to judge whether a logic error exists or not, and the keyword is analyzed to judge whether a logic error exists or not. First the line statement by looking for "#" and "; "the sign judges whether the statement starts and ends correctly, judges whether the length of the line statement exceeds the set range by the length, judges whether the Ascii code value of the input character is less than 127, judges whether the illegal character is input, and the like. Different types of syntax errors can be detected through the for loop statements, each for statement outputs a corresponding error prompt through a printf statement, and the for statement loop is terminated through a break statement. The keywords IF ELSE, ENDIF, DELAY, WHILE [ unconditional loop ], WHLIF [ conditional loop ] ENDWHL [ end loop ], and related keywords are then looked up. And for input port _ X? Output port _ Y? The variable _ V? Parsing and assigning parameters. The above syntax analysis is carried out line by line, if the controller judges that the syntax is wrong, the wrong line number, the wrong code and the wrong description are automatically recorded in the 'compiling report, TXT' text file, so that a user can conveniently search the wrong reason for modification, and the efficiency is improved. IF the logic condition of a plurality of IF ELSE nested is analyzed, firstly, the corresponding relation of IF ELSE statements is recorded, and the embedded pairing sequence is ensured not to be dislocated; then, the relative positions of the key symbols such as "," | "and the like are confirmed, and the execution parameters of the current line analysis are temporarily stored. If the logic is judged to be wrong, the controller also automatically records error codes, error codes and error description in a 'compile report' TXT text file. If there is no syntax error and logic error, the controller will compile zero error report in "compile report. TXT" text file record, and generate user program code two-dimensional array data as executing code. When the controller analyzes the control code file line by line, the controller extracts the command of the command analysis column, extracts the sequence line number of the sequence line number column, extracts the jump line number of the jump line number column and extracts the sequence of the parameters 1-8 of the parameter column according to the search keywords to analyze line by line, finally obtains analysis data, and analyzes the control code file line by line through a readline function.

As an alternative embodiment, in step S320, the two-dimensional array is 11 columns, and each column is an integer number. As shown in fig. 4, each 11 integer numbers form a group corresponding to a line sentence parsed from the text file.

As an alternative embodiment, as shown in fig. 5, in the two-dimensional array, the 1 st column is a command analysis column, the 2 nd column is a sequential row number column, the 3 rd column is a skip row number column, and the 4 th to 11 th columns are parameter columns, which are parameters 1 to 8, respectively. The parameter column is executed through the command analysis column, the sequence row number is the execution row number of the statement or the execution row number of the next statement when the condition is true, the jump row number is the row number corresponding to the jump when the condition is false, and the parameter column is the execution operation parameter of the statement. When the controller reads and analyzes the two-dimensional array row by row, the controller analyzes the two-dimensional array through a command (array column 1), and then executes a condition parameter 1 (array column 4) to a parameter 8 (array column 11), wherein the parameters 1 to 8 can be corresponding to input and output hardware ports of the controller or variables or constants. That is, the commands of the parameter 1-parameter 8 installation command analysis column (array 1 st column) act, thereby realizing the purpose of automatic programming for users. If the execution results of the parameters 1 to 8 are TRUE (TRUE), the next statement is automatically executed in sequence, namely the sequence row number (array 2) corresponding to the two-dimensional array, otherwise, if the execution results of the parameters 1 to 8 are FALSE (FALSE), the row number corresponding to the row skip row number (array 3) is automatically entered, and the next statement is executed. The execution code is obtained in this way, and the control of the user on the external automation device is realized.

As an optional implementation manner, the upper computer is a desktop computer, an all-in-one machine, a notebook computer, a tablet computer, or a mobile phone, and of course, other devices with input and display functions may also be used, which is not described herein again. The controller is connected with the upper computer through a USB line, after the controller and the upper computer are connected with each other, a mobile USB device is added on the upper computer, and a 'programming template, TXT' text file is automatically generated in the USB device. Various upper computer equipment generally have general USB interface, or can provide the USB interface through switching equipment, just realized the communication between upper computer and the controller through the USB line and be connected, easy operation is convenient, and application scope is wide.

As an optional implementation, the controller includes a storage module, the storage module is an SPI Flash, an SD card, or a TF card, and a user can select the storage module according to the use requirement. The controller supports various storage modules, and applicability is further improved.

The embodiment is only a specific example and does not indicate such an implementation of the invention.
