【技术实现步骤摘要】
本技术是一种可用于民用脉冲电表、脉冲水表、脉冲燃气表、脉冲热量表等脉冲仪表的脉冲采集中,对采集数据进行存储、处理、显示、传送等的脉冲信号多用户数据采集装置。 二
技术介绍
随着电子技术的迅速发展,数据采集、传送、处理的数据采集器近年来出现了很多,而当前用于民用电表、水表、燃气表、热量表等脉冲仪表的数据采集器在信号处理、设计原理各不相同,用途各异但存在着功能单一,抗干扰能力较差,适应性较差,或不能用于“多用户”等缺点。三
技术实现思路
本技术的目的是为民用脉冲电表、脉冲水表、脉冲燃气表、脉冲热量表等脉冲仪表提供一种抗干扰能力强,信号存储可靠,操作方便,信号采集精度高的多用户数据采集器。为达到上述目的,本技术采取的技术方案是由数据采集器、微机系统电路、键盘、显示器、报警器、电源模块等组成,形成一个有机的整体,完成对脉冲信号的采集、处理、存储、显示、传送等。数据采集器由端子、滤波电路、脉冲整形集成块、信号暂存集成块、复位集成块等组成。端子为多个,每个端子各通过一个滤波电路、一个脉冲整形集成块与信号暂存集成块联接。信号暂存集成块与复位集成块联接。端子采集的脉冲信号经过滤电路滤波后传送给脉冲整形集成块整形,脉冲整形集成块把脉冲信号整形为标准的脉冲信号,然后暂存在信号暂存集成块中,等待微机系统电路来提取。脉冲信号一旦被微机系统电路正确取走后,复位集成块对信号暂存集成块清零;否则脉冲信号仍保存。微机系统电路由单片机、带有EEPROM的复位看门狗集成块、数据选择集成块等组成。复位看门狗集成块与单片机联接,单片机与数据选择集成块联接。单片机控制数据选择集成块,对各路信号选择导 ...
