Comparing the different design method of the asic , we decide to realize our design through fpga . then , we analyze the main function of the data - collecting device which include pulse signal collecting , counting the pulse according to different time , display , storage , communicating , remote control and so on . according to some technology rules , we design the asic through verilog hdl 根据抄表器所需实现的表计脉冲数据采集、计量数据的分时段管理、显示控制、数据存储及通讯管理、远程控制的管理等功能,结合现有的一些技术规范,用veriloghdl实现抄表器的硬件电路描述。
It successfully adopts advanced digital collection system in the thesis , solves automatic collection and acknowledgement for coming information of automobiles , improves the stability and accuracy of the systems , this can provide steady basis for treating and managing measurement data scientifically and reasonably 成功地采用先进数据采集系统,解决了来车信息的自动采集与识别,提高了系统的稳定性及精确性,为科学、合理地处理、管理计量数据提供了坚实的基础。
