On November 14, the CCTV video expansion and reconstruction project of Nanjing Metro Line 1, which was undertaken by Panda Information, passed the pre-acceptance of the project. The new CCTV video system is officially put into operation, marking that Nanjing Metro Line 1 has officially entered the era of high definition.

During the implementation of the CCTV video expansion and reconstruction project of line 1, the project team continued to overcome difficulties, not only solved the technical difficulties encountered in the construction in real time, but also bravely made breakthroughs and innovations according to the actual needs of Nanjing Metro. For the first time, the front box installation mode of CCTV system with optical and electrical separation was adopted in Nanjing Metro line, which further improved the safety and stability of front-end camera equipment and the efficiency of later operation and maintenance personnel to deal with faults, and strengthens the control of equipment system stability. At present, this innovation has been used for reference by Nanjing Metro new lines, and will be popularized in the follow-up lines.

Panda Information not only pays attention to the construction of new lines, but also explores the overhaul and reconstruction market of existing lines. The smooth implementation of the project has supported the development of Nanjing Metro and won the praise of the customers and supervisors. Meanwhile, it has accumulated experience for the company to undertake the metro operation overhaul and reconstruction project, which is another expansion of Panda Information rail transit communication business.
