该用户电路板诊断仪,是我院计算机系,徐星宁教授等人研究设计的,经过在北京市话局修理程控交换机用户板上试用,获得成功。目前,我国已引进安装开通了数十万门 AXE-10程控数字电话交换机,这些交换机每年都要换下大量的有故障的用户电路板,这些电路板送到国外修理,不但影响使用而且还要花大量的外汇(换一块板需426美元,修理一块板需250美元),徐星宁教授等人采用部分进口器件设计研制的用户电路板诊断仪,为北京市话局修复了近40块用户电路板,送到机架
The user circuit board diagnostic apparatus, is our hospital computer science department, Professor Xu Xingning and others research and design, after the Beijing Municipal Bureau of telephone repair program-controlled switch board trial, to be successful. At present, China has introduced and installed hundreds of thousands of AXE-10 program-controlled digital telephone switches. Each of these switches has to replace a large number of faulty user circuit boards. These circuit boards are sent abroad for repairs, which not only affect the use but also Spent a lot of foreign exchange (for a plate to be 426 US dollars, to repair a plate to be 250 US dollars), Professor Xu Xingning and some other imported devices designed and developed by the user circuit board diagnostic apparatus for the Beijing Municipal Bureau to repair nearly 40 user circuit boards, To the rack
