摘 要
本论文介绍了一种名为”注射器”的智能设备,采用单片机STC89C52进行控制。该注射器具备测温、加热或制冷、注射控制和显示等功能,旨在提高注射过程的自动化和精准性。首先,注射器通过DS18B20温度传感器测量温度值。当温度值超出预设的上下限范围时,系统会自动进行加热或制冷操作,以调节温度到合适的范围。其次,当温度在预设的上下限范围内时,用户可通过注射按键启动注射器。注射器采用步进电机实现正转,进行注射操作。当注射时间达到预设时间时,蜂鸣器会提醒用户持续3秒,并通过拔出按键触发步进电机反转,将注射器拔出。通过按键操作,用户可以设置温度的上下限值和注射时间,以满足个性化需求和适应不同的使用场景。此外,注射器配备LCD1602显示屏,能够实时显示温度的上下限值、当前温度和注射时间等信息,方便用户监测和了解注射器的状态。通过以上功能的实现,该注射器提供了智能化的注射过程控制和监测。用户可以根据设定的温度范围进行加热或制冷操作,确保注射液的温度符合要求。同时,注射器具备精确的注射控制,通过设置注射时间和拔出操作,实现注射的准确性和安全性。LCD1602显示屏提供了直观的信息展示,方便用户了解注射器的各项参数和状态。
该注射器的研究和应用对于提高注射过程的自动化水平,提升注射的准确性和安全性具有重要意义。未来的研究可以进一步优化和扩展该注射器的功能,以满足不同场景下的注射需求,并探索其在医疗领域中的应用潜力。

Abstract
This paper introduces a smart device called the “Smart Injector” that is controlled by the STC89C52 microcontroller. The Smart Injector is designed to enhance the automation and precision of the injection process. It incorporates features such as temperature measurement, heating or cooling, injection control, and display capabilities.The Smart Injector utilizes the DS18B20 temperature sensor to measure the temperature. If the temperature exceeds the preset upper or lower limits, the system automatically initiates heating or cooling operations to adjust the temperature within the appropriate range. When the temperature falls within the preset limits, users can activate the injection process by pressing the injection button. The Smart Injector employs a stepper motor to perform the injection, rotating in the forward direction. Once the preset injection time elapses, the buzzer alerts the user for 3 seconds, and pressing the retract button triggers the stepper motor to reverse and retract the injector.Users have the flexibility to set the upper and lower temperature limits as well as the injection time using the buttons provided. This allows for customization to meet individual requirements and adaptability to various usage scenarios. The Smart Injector is equipped with an LCD1602 display screen that provides real-time information on the temperature limits, current temperature, and injection time. This enables users to monitor and stay informed about the status of the injector.By incorporating these functionalities, the Smart Injector offers intelligent control and monitoring of the injection process. Users can ensure the injection fluid’s temperature meets the desired specifications by adjusting the temperature within the preset range. Moreover, the Smart Injector guarantees precise injection control, ensuring accuracy and safety by setting the injection time and utilizing the retract button. The LCD1602 display screen provides a user-friendly interface for clear information presentation, facilitating easy monitoring of key parameters and status.
The research and application of the Smart Injector are of significant importance in enhancing the automation, accuracy, and safety of the injection process. Future studies can focus on optimizing and expanding the functionality of the Smart Injector to cater to diverse injection requirements and explore its potential applications in the medical field.
