Description: 理工大学的一篇学士论文，个人感觉值得借鉴。用单片机作控制系统。干式变压器温度控制系统是维护干式变压器运行的重要部件，能有效防止变压器温升过高而引发事故，还能促进变电站的科学管理，通过降低温度实现变压器的经济运行，其工作可靠性的高低和操作是否方便将直接影响到干式变压器的运行质量。本设计从系统功能、硬件结构和程序设计等方面介绍了一种基于AT89C51单片机为核心、Pt100铂电阻为温度传感器并以NE555定时器作为A/D转换器，拥有看门狗电路、LED显示及简单的按键系统构成的干式变压器温度检测仪。-Polytechnic University, a Bachelor of papers, personal feel is worth learning from. With single-chip microcomputer for control systems. Dry-type transformers temperature control system is the maintenance of dry-type transformers to run the important parts, are effective in preventing excessive transformer temperature rise caused by the accident, but also to promote the scientific management of substation, the transformer by reducing the temperature to achieve the economic operation, reliability of its work the level of operating convenience and will directly affect the operation of dry-type transformer quality. The design features from the system, hardware design, structure and procedures introduced AT89C51 single-chip microcomputer-based at the core, Pt100 platinum resistance temperature sensor and timer NE555 as A/D converter with a watchdog circuit, LED display and simple push-button system consisting of dry-type transformers temperature detector.

Description: 本设计的指导思想是利用红外发光管发射红外线，红外接收管接收此红外线，并将其放大、整流形成高电平信号.当有人或物挡住红外光时，接收管没有接收到红外信号，放大器将输出低电平，同时将这个电平信号送入单片机进行控制计数，并经译码驱动电路使数码管显示数值。这样就得到要统计的人或物的数量。-The design of the guiding idea is to use infrared emission infrared LED and infrared receiver to receive the infrared control and its amplification, rectification form a line level signal. When there is someone or something to block infrared light, the receiver does not receive infrared control signals, the amplifier output low, while the level control signals into single chip count, and driven by the decoding circuit to digital display value. This will be the number of persons or things to statistics. Platform: |
