承德钒钛冷轧薄板有限公司通过库区无人化系统的建设,实现了冷轧钢卷库的智能化管理。系统采用行车自动作业、行车位置跟踪、吊卷防晃、行车防碰撞技术,实现库区安全有序管理,并有效提高库区的作业效率。系统按照位置可分为地面服务器与位于库区高处作业的行车本体。地面服务器与行车原系统未通过WiFi无线网络通信,存在信号覆盖范围小、安全性差、稳定性低等问题。因此应用5G+工业互联网技术进行无人化库区场景的应用测试,测试效果良好,且有效改善以上网络问题,本次测试为5G技术在钢铁工业中的应用提供借鉴。

当今数字媒介技术下沉为社会的操作系统，数字账号也成为人们维系数字化生存的基础设施。数字账号是一种由数据关系组成的数码物，也是承载人们数字关系的枢纽与中介，并由此开启了人们数字化生活的周围世界与存在姿态。但数字账号在维系人们的数字存在的同时，也带来了个体存在的外化与非个体化。进而，作为物质性装置的数字账号，构序了一场数字生命政治，账号化意味着数字生命政治的入序，去账号化则意味着数字生命权力的决断与治安处罚，两者共同规制着数字生命的存在方式。

A unique nest-type catalyst has been designed with a nest of oxygen capture surrounding catalytic Pt centers, which shows much promoted performance, on the base of Pt/C catalyst, for oxygen reduction reaction(ORR). The nest is constructed with nitrogen-doped carbon matrix(NCM), derived from the controlled carbonization of PANI precursor, to cover Pt/C catalyst. The unique structure of the catalyst(denoted as NCM■ Pt/C) has many merits. Firstly, it can capture oxygen both in air and in acidic electrolyte. Compared with naked Pt/C, it is found that, in air, the oxygen concentration within the porous nest of NCM surrounding Pt/C particles is ~13 times higher than atmospheric oxygen concentration and, in acidic electrolyte, the concentration of activated oxygen over the catalyst NCM■ Pt/C rise to~1.9 times. Secondly, the NCM nest offers a special electronic modulation on Pt centers toward modified ORR kinetics and then catalytic performances. With these merits, compared with Pt/C, the NCM■ Pt/C catalyst shows 3.2 times higher turnover frequency value and 2.9 times enhanced specific activity for ORR with half-wave potential at 0.894 V. After 50,000 sweeping cycles, the NCM■ Pt/C catalyst retains~66% mass activity and still has advantages over the fresh Pt/C catalyst. We envision that the nest-type catalyst provides a new idea for progress of practical Pt/C ORR catalyst.
