  • 基于AVR单片机的闭环控制系统

      针对科研实验中对拉压千斤顶加载过程控制的需要,采用ATmega128单片机控制步进电机进而实现对执行系统的电动泵站实行自动控制。对力和位移的数据采集与处理及用步进电机控制电动泵站手柄的技术细节作了重点描述。通过单片机的A/D变换器对AMP放大模块采集的电桥信号作量化处理,千斤顶的操控手柄位置依电动油泵阀门开启的方向和大小作若干定位,单片机根据力或位移传感器信号,实时控制步进电机驱动手柄旋转到相应操控位置。   Abstract:   This article describes the use of ATmega128 AVR microcontroller series of DBS electric pumping stations and QF100/200 separate twoway hydraulic jack to automate the process of manipulating the work of the technical content. Articles on force and displacement data acquisition and processing, and stepper motor control electric pump with the handle of the key technical details were described. Through the MCU’s A / D converter module is collected on the AMP amplification quantify the signal bridge, jack handle position control valve opening according to the direction of electric pumps for a number of positioning and size of the microcontroller based on force or displacement sensor signals, real-time control stepper motor drive control handle rotate to the appropriate location.

  • 基于IC卡的新型供暖计费系统设计

    将现行的供暖计费方式由按建筑面积计费变为按消耗的热能计费是供暖计费方式发展趋势,为了满足这一计费方式变化的需要,设计了基于IC卡的预付费式新型供暖计费系统,通过测量用户采暖系统进出口的温度和流量,计算用户消耗的热能,利用IC卡记录用户预付费的金额和当年热能的单价,根据热能消耗和当年热能的单价计算用户采暖费,根据实际发生的供暖费用和预付费金额控制供暖的开停,这一计费方式的变化使供暖计费更趋合理。 Abstract:  It is trend that the mode of heat charging is changed from billing by building area to by thermal energy. In order to meet the needs of heat charging mode changing, a new system of heat charging based on IC card is proposed. The user?蒺s energy consumption is calculated by measuring the user inlet and outlet temperature and flow,using the IC card to record the prepaid amount and the current price of heat. The user?蒺s heating costs is calculated according to energy consumption and current price, according to actual heating costs and prepaid amount,the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption
