The technical report of electronic competition is a type of scientific and technological report. Why do you choose this kind of report to introduce? This is because students who participate in electronic competitions or science exhibitions must submit a technical report, and in electronic competitions, the technical report accounts for 50 points out of 150. The ability of engineering students to write science and technology is relatively poor. It is really difficult and intensive to finish this work (including design and production) in three days. Students often feel at a loss, which leads to poor writing level of technical reports. Therefore, it is necessary to introduce the writing methods and skills of technical reports to students.

It should be noted that if there are requirements for the content, format, layout and font size of the technical report in the topic selection, it should be written as required; If there is no such requirement, the technical report can be compiled flexibly, and the following contents are for reference only.

In fact, the genre and structure of technical reports and scientific papers are basically the same, so technical reports can refer to the format of scientific papers, namely: title, author, abstract, keywords, introduction, body, conclusion, thanks, appendix and references.

Since these contents are all introduced in the writing part of scientific papers, I don't intend to repeat them here. Only some suggestions are put forward for writing the technical report of electronic competition:

(1) Due to the limitation of space, the number of words in scientific papers published in journals is generally controlled between 3,000 and 5,000, while the number of words in technical reports can be relaxed.

In view of the fact that electronic contests are system-level topics, there are many contents to be compiled, and some of them need to be accompanied by a list of programs or components, so the number of words should be equivalent to that of graduation thesis, about1.5000 words.

(2) The rigorous structure and standardized writing of scientific papers are the basis of scientific writing. You can learn and imitate when writing technical reports, but you can't copy them mechanically. For the format requirements of scientific papers, we should use them flexibly, such as abstract, keywords, appendix, references, thanks and other important items should be expressed in words, while the main items such as title, author, introduction, text and conclusion can only be used as the steps to write and arrange technical reports. Some of these steps can be omitted, such as introduction, thanks, etc. , which are unnecessary, whether to adopt these steps can be decided according to the situation.

(3) The cover of the technical report shall be clearly marked with the title, accounting for 1 ~ 2 lines. The title should be straightforward and eye-catching, such as "Technical Report on Design and Manufacture of Simple Digital Storage Oscilloscope". Sometimes you can add subtitles as needed. Under the heading, author, unit, instructor, date, etc. It should be noted. These projects can be written as required. For example, some works require anonymous participation in the review, so it is impossible to indicate the unit to which the author belongs.

(4) The focus of the technical report is the main body, and it is also the place that consumes the most ink. The text should cover the secondary and tertiary titles (or columns).

Taking "Technical Report on the Design and Manufacture of Simple Digital Storage Oscilloscope" as an example, it is suggested that the title should be designed as follows:

Table of Contents (separate page number)

Abstract and keywords (in Chinese and English)

About 300 to 500 words

AbstractandKeyWord (English)

1. Design tasks (or design themes) and requirements (or technical indicators)

1. 1 design task (which can be extracted from the design task book)

1.2 technical indicators (which can be extracted from the design task book)

1.3 topic evaluation (if it is a competition topic, you can evaluate the focus, difficulty and practical value of the topic; If it is an exhibition work, explain the innovation point)

2. Scheme comparison and demonstration

2. 1 Comparison and selection of various schemes

Option 1: XXX

Option 2: XXX

Option 3: XXX

According to the technical indexes and requirements of the project, several general implementation schemes are put forward and given in the form of block diagram. Then discuss the characteristics, difficulty and cost performance of each scheme, analyze and compare their advantages and disadvantages, and finally explain which scheme to choose and why to choose this scheme. The reasons for the final adoption of this scheme can be explained from the aspects of meeting the requirements of technical indicators, cost performance and current actual conditions (components and equipment). Some systems need to assign technical indicators and interpret them accordingly.

2.2 Scheme demonstration

With the help of illustrations, flowcharts, tables, etc., the selected scheme is demonstrated and its working principle is analyzed. The demonstration should be as detailed as possible, and the level reached by this scheme and the technical situation at home and abroad should also be evaluated. Pay attention to the use of mathematical deduction and demonstration, which is more rigorous.

3. System hardware design

According to the selected general block diagram, design and select the main circuit respectively, and its contents should include:

3. 1 Overall system design (design ideas, design steps), system calculation.

3.2 Design of unit circuit (or functional module) and calculation of unit parameters.

3.3 Function and working principle analysis of unit circuit (specific circuit diagram of unit).

3.4 Design and implementation of the play part (if the play part is completed, it should be highlighted, which is a good score).

3.5 Electrical schematic diagram (which can be included in the appendix).

4. System software design

Software design includes MCU and CPLD.

4. 1 program overall flow chart

4.2 Flow chart of each functional module

4.3 Program List (which can be included in the appendix)

5. Assembly of the system

5. 1 PCB drawings (can be included in the appendix)

5.2 Structure diagram and process description of the whole machine

5.3 Panel drawing and description of adjustable parts

6. System debugging

Test all indicators according to the requirements of the topic, and pay attention to the excavation points. When testing each index, the definition or meaning of the index should be given (such as the strict definition of sensitivity and signal-to-noise ratio). Then test them one by one. 6. 1 Circuit test scheme (method)

According to the system function and index, the test scheme (method) is drawn up, usually in the form of block diagram.

6.2 test instruments

Select appropriate test instruments, such as DC voltmeter (preferably multi-digit digital meter) for DC voltage test; Ac voltage test, using low-frequency millivoltmeter below tens of kilohertz and high-frequency millivoltmeter above hundreds of kilohertz; Frequency test adopts frequency meter; Waveform test adopts oscilloscope. Indicate the instrument name, model and test accuracy.

6.3 Test results

According to the requirements, the test items should be marked with test conditions, such as input signal, output signal, power supply voltage, etc. Test instruments and other conditions need to be marked: then list the data (in some cases, multiple measurements are needed, so it needs to be marked at this time); Finally, the technical indicators achieved are explained and compared with the technical indicators required by the design, which shows the accuracy of the final test indicators.

6.4 Take part in the test

Part of the test questions can be used as a separate item, highlighting key points and increasing the weight of the test paper.
