第 11 屆 海峽兩岸計量學術研討會 Ｉ-0006 2016 年 11 月 1 日~ 3 日 臺灣‧桃園‧中壢 中原大學 停车场计时收费在线检测系统设计与研究 Design Analysis about the online measurement of parking time charge system 郑云林 1 李峰 1 鲜青龙 1 1 新疆维吾尔自治区计量测试研究院 E-mail: ZYL666511@163.com 摘要 error on present moment and parking time error 针对城市停车场计时收费引发的贸易纠纷 exceeds a predetermined error is the main reason 现象进行分析，得出进出口时刻不同步和停车 for the trade disputes ，also is the reason for the 计时误差超差是停车场计时收费系统引发贸易 electronic parking meters is substandard. At present, the government metrology department of 结算双方矛盾的主要原因，也是电子停车计时 measurement of the electronic parking meters is 收费表不合格的主要原因。目前，政府计量部 the use of field testing, the method of testing is 门对停车场电子计时收费系统的检测采用现场 using the standard clock (including universal 检测，即用标准时钟（包括通用计数器或者日 counter or day time difference tester). This service 差测试仪）对计时计费系统的当前时刻检测、 is based on the traditional island state of 时钟日差和停车计时误差进行检测。该检测方 measuring instruments carried out, its 法是基于传统计量器具的孤岛状态开展的服 disadvantage , the first is inefficient, the second discrete uncontrolled. In order to overcome the 务，其不足一是效率低下，二是离散不受控。
