The large-screen display system of the dispatch and rush-repair center of Wuxi China Resources Gas Co., Ltd. (hereinafter referred to as "Wuxi China Resources Gas") was first built in 2010 and is a core component of the entire dispatch center. It plays an irreplaceable role in pipe network real-time monitoring, gas source dispatching, rush-repair and inspection dispatching, and emergency command. According to the changes and deepening of Wuxi China Resources Gas's business in recent years in pipe network data collection and monitoring, gas source dispatching, cloud rush-repair, and pipe network GIS, as well as the rapid development of visualization technology, combined with the company's smart operation development philosophy and planning, in order to more clearly, beautifully, and richly display the company's business situation and various data analysis results, it is proposed to carry out the upgrade and reconstruction of the large-screen visualization system.
