标题: 如何实现0-10v或者4-20ma模拟量的高精度采集传输 标签: 0-5v,0-10v,0-20ma,4-20ma,模拟量采集,adc模数转换,电压电流采集,温湿度采集,称重模块,变送器 文档介绍: 本文基于综科智控开关量模拟量混合模块介绍如何实现0~5V，0~10V，0~20ma，4~20ma模拟量信号的高精度ADC采集转换，采集精度高达24bit，最多可以实现8通道同时采集转换，该模块同时还配有8路光耦隔离开关量输入以及8路光耦隔离晶体管输出，功能强大，适合于对精度和稳定性要求较高的工业或者物联网场合。(Title: How to achieve high precision acquisition and transmission of analog data of 0-10V or 4-20mA Label: 0-5V, 0-10V, 0-20mA, 4-20mA, analog data acquisition, ADC analog to digital conversion, voltage and current acquisition, temperature and humidity acquisition, weighing module, transmitter Document introduction: This paper introduces how to realize high precision ADC acquisition and conversion of 0~5V, 0~10V, 0~20ma, 4~20ma analog signals based on the integrated module of fully mechanized intelligent control switching analog quantity. The acquisition precision is as high as 24bit, and the 8 channel simultaneous acquisition and conversion can be realized at most. The module is also equipped with 8 optocoupler isolation switches and 8 optocoupler isolating crystals The tube output is powerful and suitable for industrial or Internet of things with high accuracy and stability.)

说明：  单片机I/O口控制红外发射管，模拟格力空调遥控器的代码。典型应用：上位机发送一个通用的“开机，温度，模式……”命令，单片机自动发射出和遥控器一摸一样的波形，实现智能遥控器的功能。 (MCU I/O port control infrared emission control, analog Gree air conditioner remote control code. Typical applications: host computer to send a generic &quot boot, temperature, mode ... ...&quot command, microcontroller and the remote control automatically emit the same wave first touch, intelligent remote control functions.)

说明：  东西、南北两干道交于十字路口，各干道有一组红、绿、黄三个指示灯，指挥车辆和行人安全通行。南北方向为主干道，通行时间为35秒；东风方向为支干道，通行时间为25秒。通行时间最后3秒，绿灯灭，黄灯闪烁，黄灯闪烁完毕变更通行车道。通行时间由数字显示器显示，黄灯3秒闪烁不单另计时。 特殊情况控制通行方式控制，用按键开关K1控制主道通行，支道禁行，K2控制支道通行，主道禁行，特殊情况控制通行放行。 有紧急情况时用按键开关K3控制两道均为红灯。(The east-west and North-South arterial roads intersect at the intersection. Each arterial road has a group of red, green and yellow indicator lights to guide vehicles and pedestrians to pass safely. The north-south direction is the main road with a traffic time of 35 seconds; the east direction is the branch road with a traffic time of 25 seconds. At the last 3 seconds of the traffic time, the green light is off, the yellow light is flashing, and the yellow light is flashing to change the traffic lane. The traffic time is displayed by the digital display, and the yellow light flashes for 3 seconds, not only for another time. Under special circumstances, control the way of passage. Use key switch K1 to control the passage of main road, Branch Road, K2 to control the passage of branch road, main road and special circumstances to control the passage and release. In case of emergency, use key switch K3 to control two red lights.)
