Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Fig. 1 shows a preferred embodiment of a method for opening a serial port of a super terminal in a power acquisition terminal based on a usb flash disk according to the present invention. It should be mentioned that the power acquisition terminal of this application has super terminal software, and super terminal is as general serial interactive software, can be used to visit the server under the different systems of far-end, and this application downloads super terminal to the power acquisition terminal in, and the power acquisition terminal is debugged in its control of ingenious utilization, has saved PC, serial port line etc. can use manpower and materials resources greatly sparingly.
Meanwhile, the USB flash disk adopts an external bus standard, so that the connection and communication between the power acquisition terminal and other external equipment such as a computer can be standardized, and the power acquisition terminal is designed based on the QGDW 1375.2-2013 Power consumption information acquisition System type Specification for Power consumers and is completely consistent with the current power acquisition terminal in hardware and structural components.
The application adopts a USB flash disk mode to open the serial port of the super terminal in the power acquisition terminal, and particularly comprises the following steps,
s1, identifying the USB flash disk, and judging whether the file size and the content of the USB flash disk meet the requirements or not;
s2, acquiring the content of the U disk file, and creating a new first digital character string according to the content;
s3, obtaining each digit in the first digit character string, left-shifting the digit by 1, wherein the left-shifting number is equivalent to the size of the obtained current digit to obtain a plurality of new second digit character strings, and operating the plurality of new second digit character strings to obtain a new third digit character string;
and S4, assigning the third digital character string to the super terminal serial port, opening the super terminal serial port, and monitoring the debugging state.
The file in the U disk is written in by a technician through a PC in advance, the naming format of the file can be various, and the naming format is determined according to actual needs.
Specifically, in the step S1, it is determined whether the content of the U-disk file meets the requirement, and the following determination method is adopted,
s11, traversing all numbers in the file, judging whether all numbers are located between 1 and 31, if so, executing a step S12, and if not, executing a step S13;
s12, sequentially judging whether the odd-numbered digits in the file are numbers and the even-numbered digits are commas, if so, continuing to execute subsequent operations, and if not, executing a step S13;
and S13, returning an error.
The subsequent operation is specifically to determine whether the semicolon is encountered, if yes, the operation of sequentially determining whether the odd-numbered digits in the file are numbers and the even-numbered digits are commas is ended in step S12, and if not, the operation of step S12 is continued. Through the judgment of the number division, the fragments can be effectively and quickly selected for subsequent utilization, and the efficiency is improved.
And the determination of the size of the usb disk file in step S1 is corresponding,
s15, judging whether the U disk file is empty, if not, executing a step S16, and if so, executing a step S13;
s16, judging whether the size of the U disk file exceeds the capacity of the buffer area, if yes, executing step S13, and if not, executing step S11. In this embodiment, the buffer capacity is 2Mbit, and of course, the specific buffer capacity is determined by the power acquisition terminal itself.
As described above, after the usb disk file is determined to meet the requirement, an operation of forming a new character string is performed, and the contents of the usb disk file used in forming the character string are the partial segment contents of the usb disk file sequentially determined in step S12 when the determination in step S12 is completed.
In this way, in step S2, a new first numeric character string is created according to the content, and corresponding to the first numeric character string, S21, the numbers in the partial segment content are sequentially extracted and arranged to form the first numeric character string, and the even number of the first numeric character string is comma. When the numbers of the partial segment contents are extracted, if the same number is encountered, the number is only extracted once, obviously, the extracted number is necessarily the number appearing for the first time, and the new first number character string formed in this way has the characteristic of different composition numbers.
In the step S3, the new second numeric character strings are operated to obtain a new third numeric character string, specifically, in S31, the new second numeric character strings are subjected to an or operation to obtain an or operation result character string.
In order to enable the formed character field to effectively activate the super terminal serial port, after the step S31 is executed, the operation is further performed, and S32, the or operation result character string is converted into a 32-bit character string, so as to obtain the third numeric character string.
And after the super terminal is activated, the super terminal is in a monitoring and debugging state, namely, the power acquisition terminal interacts with the super terminal through the serial port, the super terminal records log information and creates a file storage log in the USB flash disk. Here, the created file is named in a year, month, day, hour, minute, second format.
According to the invention, on the premise of not changing the original structure of the power acquisition terminal, the super terminal is directly opened in a USB flash disk mode, so that terminal debugging information is sent to the super terminal, and real-time monitoring and debugging of the terminal in a completely wireless state are realized, thereby not only facilitating field operation and maintenance of the power acquisition terminal, improving timeliness, ensuring the accuracy of log information storage, but also saving cost.
In addition to the above-mentioned modifications, other similar modifications are also included in the scope of the modifications of the present invention, and are not described herein in detail. While embodiments of the invention have been shown and described, it will be understood by those skilled in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
