Description: 本程序是一种先进的充气电缆气压自动监测系统的程序。其特点是可以对电缆线路上各点的气压值进行24小时实时监控。使管理人员可以实时掌握电缆内的气压情况,及时发现漏气隐患,从而保证通信畅通。 系统采用性能价格比较好的AK-3 型压力传感器,直接输出0~5V电压信号。电压信号的转换采用串行接口的12位A/D转换器TLC2543,精度和速度都能很好地满足系统要求。仪器的CPU采用目前低价位但技术十分成熟的AT89C51,仪器的LED数码管显示/驱动芯片采用接口简单但功能强大的HD7279。本系统提供日历时钟电路,在方便用户确定时间的同时,还可以为定时通信提供依据;在发生报警时还能向上位机提供确切的报警时间。同时系统还设计了RS-232总线的通信接口电路,每到整点就要向上位机发送各路气压值,供上位机记录分析。 本系统软件分两大部分,键盘中断和定时中断。工作流程是这样的:每50ms就要进行AD转换,尺度变换,比较是否越位,是否报警等操作,如果有按键动作,执行键盘中断程序。键盘解释在5s之内有效。 如需详细的硬件电路与说明文档,请与作者联系!-err

Description: 本系统的控制部分是以89C51为核心,采用集温度采集、A/D转化于一体数字温度传感器18B20作为温度处理部分。键盘控制接口采用键盘接口7279,通过其可以设定温度,设定PID算法的参数,并且可以设定当前时间,进行温度与时间显示的切换.采用数码管显示,可以实时显示实际温度。主电路是由光偶和晶闸管所组成的开关电路。控制电路通过PID算法,产生PWM波来控制主电路的通断,从而控制电炉的输出功率,达到温度控制的目的.-The system control part of the 89C51 as the core, the use of set temperature acquisition, A/D conversion in the integrated digital temperature sensor 18B20 treatment as part of the temperature. Keyboard control interface using the keyboard interface 7279, can be set through its temperature, set the parameters of PID algorithm, and can set the current time, temperature and time display switch. Using digital control, it can be real-time display the actual temperature. Main circuit is a dual optical and composed of thyristor switching circuits. Control circuit through the PID algorithm, generate PWM wave to control the main circuit of the on-off and thus control the output of electric power, to achieve the purpose of temperature control.the use of set temperature acquisition, A/D conversion in the integrated digital temperature sensor 18B20 treatment
