        范文1:Automobile anti-collision system

        这篇论文讨论了汽车防碰撞系统。为了降低汽车的碰撞概率,提高汽车行驶的安全性,在安全系统方面、人工智能方面也要求越来越高。通过合理地设计防碰撞的软件系统,降低误警率、误判率。系统能够通过正面以及结合侧面的红外测障碍来判断下一步的工作方向,从而达到防碰撞的安全效果。
 
With the more and more intelligent and automatic development of automobiles at home and abroad, the application of MCU in automobile is more and more extensive, and the application of single chip microcomputer in automobile greatly improves the safety, comfort, reliability and economy of the driving. In order to reduce the collision probability and improve the safety of vehicle driving, it is also required to be more and more high in safety system and artificial intelligence. By rationally designing anti-collision software system, we can reduce false alarm rate and misjudgment rate. The system can judge the direction of the next step by the front and the side infrared measurement obstacle, thus achieving the safety effect of anti-collision. This paper briefly reviews the application of single chip microcomputer in the safety of vehicle driving.
 
Single-chip computer is more and more important for modern automobiles, widely used in all aspects of automobiles, and with the integration of various components, play a greater effectiveness. Of course, this also raises some hidden dangers, such as the speed increase, as well as from the impact of the external environment, it is easy to traffic accidents, and this anti-collision system software design is the use of infrared, ultrasonic, nano-wave radar to detect the external environment, feedback, analysis, judgment, help the driver to make better judgments, Reduce the occurrence of traffic accidents.
 
The system uses ultrasonic to measure the relative distance ahead, when there is a sound wave back, indicating that there is obstruction ahead and to determine whether there is movement in front of the object, if there is movement, then the direction of its movement with the car or reverse, so as to alarm, automatic braking and automatic steering, And before the turn to the side of the infrared monitoring side of whether there is obstruction, then the steering or not. The system mainly lies in the ultrasonic distance measurement, the monolithic single chip computer to the information processing feedback judgment. Speed measurement and ranging is based on the principle of wave reflection, the use of waves and send and receive the time difference between the measurement and measurement. The wave is transmitted in a straight line, which is emitted in one direction and can detect obstructions in the front. Of course, the transmission of ultrasound will be affected by the outside world, but can be ignored, according to the 20 ℃, dry, wind-free environment, sound waves to $number m/s speed to calculate. When there is echo, the time difference between the recording and receiving, the speed of collecting the car, the calculation, judgment, processing feedback display on the display screen, and whether to brake, automatic steering, if necessary, emergency alarm. The overall structure of the system is shown in Figure 1.
 
When the vehicle starts, the system will monolithic MCU, LCD12864 display and so on initialization, and then the system of ultrasound, sensors, etc. to start work, collect all the data and compare, when the vehicle in a dangerous state, the system issued an alarm to remind the driver to brake, After the vehicle enters the safe driving condition, the alarm is discharged. If the driver does not have any steering or braking behavior, the system will control the auxiliary braking and steering to avoid the occurrence of accidents. The mainstream program is shown in Figure 2.
 
After starting the vehicle, the system collects, calculates, analyzes and processes. When there are obstacles in front of the vehicle, the ultrasonic wave detects it and feeds it back into the MCU, calculates the distance between the two, compares it with the distance S1 set in the system, and calls the actual speed of the vehicle to compare with the set speed V1. When S>s1, VV1, the vehicle is in danger, the system must carry on the emergency alarm, the auxiliary braking and the turn.
 
In the distance, obstacle speed, direction detection, the system will first close the interrupt timer, after the launch of the ultrasonic signal, when there is a return, the system opened the interrupt, and start the timer, when there is a result, the first count the distance between the two, there is a second echo, combined with two and the speed of the car, calculate the velocity of obstacles , they are nested in the same direction and in the reverse way, to determine the orientation.
 
The design system is compared with the previous one, its advantages are mainly in the ability to detect the obstruction in front of the movement or not, can determine the vehicle in a dangerous or safe state, and has the independent braking, steering function, can effectively guarantee the safety of vehicles. And the display on the speed and the distance from the obstacles in front, so that the driver more intuitive understanding of the state of the vehicle, to achieve practical results. At the same time, fully consider the feasibility and performance of the system, the use of ultrasonic radar to achieve the purpose of ranging, close alarm, safe distance within the braking steering function, to the car to protect the safety.
 
        范文2:Research on dialogue

这篇论文讨论了对话。对话不仅是一种语言交换和思想交流的方式,也是一种概念或理念,更是人的交往与存在方式。在人类历史的进化过程中,人们始终在日常生活中进行着对话,从不同的角度思考对话,并从不同的视角来理解和认识对话。
 
Dialogue is not only a general sense of language communication and ideological communication, is also one kind of idea or the idea, is the human contact way and the existence way, is a kind of association "I" and "You" the soul, the emotion, the life significance and the life value activity, sets the intersubjectivity, the elaboration, the reconsidering in one. The dialogue should adhere to the principle of equality, the principle of openness, the principle of artistry and the principle of generative.
 
In the evolution of human history, people always have dialogues in their daily life, thinking in the mind of dialogue, and understanding and understanding of dialogue from different perspectives. Since modern times, Western philosophy has experienced "linguistic turn". Dialogue has increasingly become an important theoretical and practical issue. Buber, David burm, Bakhtin, Habermas, Gadamer and other thinkers profoundly elaborated the connotation of the dialogue from their respective perspectives, and actively practiced the dialogue. Tracing the theoretical origins of the development of dialogue is helpful to peep into the essence of dialogue and to understand the basic ideas, viewpoints and methods of dialogue.
 
Since modern times, scholars such as Buber, David burm, Bakhtin, Habermas and Gadamer have expounded their dialogue ideas and theoretical viewpoints.
 
Buber in "People and people" in the "I-You" relationship of "real dialogue." He divided the dialogue into three types: true dialogue, technical dialogue, and a monologue of dialogue. The dialogue in the "I-You" relationship is a real dialogue. Buber describes the "I-you" relationship as a kind of harmonious encounter, in the "I-You" relationship, "you" to the "I". The "I" Answer to "you" and establish a dialogue relationship. The second is the technical dialogue that is simply aroused by the need for objective understanding. The real dialogue is implicitly hidden in the dark corners of all forms, and the interlocutor has to dig out the meaning from the other's vast amount of discourse information. The third is to dress up as a dialogue monologue. The two or more people who met did not establish a relationship, just to talk with themselves in a roundabout and circuitous way. "I" Never showed, "you" also never came. Among them, the dialogue of the "I-you" relationship represents the persistence of the human spirit.
 
David burm in order to deal with the problem of human communication under the rule of technological rationality, this paper puts forward the theory of "Boehm dialogue", which is widely admired and applied, from the thinking of hiding behind the dialogue. He begins with the etymology of "dialogue": "dialogue" stems from the Greek word "dialogos". "Dia" here represents "crossing", "Logos" means "word". means "meaning." So。 "Dialogue" is the passage and flow of meaning between people, and therefore the emergence of a new "understanding and consensus" between the groups to generate some "shared meaning." In the way of "shared thinking", the interlocutor overcomes the deficiency of "divisive thinking" and "thinking Assumption", and then gets the whole "shared meaning". In the dialogue of sharing and participation, human beings can expand their own space of existence and development.
