The invention provides a touch-pen-associated data transmission system and a touch pen matched with the same, relating to a data transmission technology. The touch-pen-associated data transmission system comprises an intelligent tool and a touch pen, wherein the intelligent tool comprises an intelligent tool microprocessor system, a touch screen system and an intelligent tool communication module. The touch pen comprises a touch pen shell, wherein a touch pen microprocessor system is arranged in the touch pen shell, and the touch pen microprocessor system is connected with a touch pen communication module which is communicated with the intelligent tool communication module. The intelligent tool microprocessor system is used for carrying out data information transmission with the touch pen communication module through the intelligent tool communication module. Through adopting the design, the touch pen can play a role of a bridge used for data transmission among a plurality of intelligent tools, for example, can be used for substituting a flash disk and is more convenient to use without the need of carrying out splicing with the intelligent tools.
