【正文】 nd advanced work management tools. According to statistics, there are currently more than 70% in the use of the work equipment running in equipment factory default configuration, that is to say, the majority of customers in work construction only pay attention to the pursuit of high performance work equipment, but in the use of the process is the lack of a according to the actual situation of work reasonable planning and effective management of work equipment, leading to many a very useful function is unable in the work system to play a role in. The development and popularization of work technology, the optimization of Shangqiu occupation campus work management has laid a good foundation. In this paper, bined with the current occupation of Shangqiu campus work construction present situation and the existing problems, introduces some new technology, put forward the corresponding optimized design scheme, aimed at the construction of the campus work to provide some ideas, make Shangqiu occupation around the campus work to construct economical, practical, and has a forwardlooking, real occupation of Shangqiu teaching, scientific research, management to play as much as possible great benefit.
