In this way, the singlechip control system 102 is used to collect and store the state information of the numerical control machine by using the first wired network port 101, and control the mobile communication network module 103 to send the state information to the server. Therefore, the wireless transmission of the state information of the numerical control machine tool is realized, the operation difficulty of the installation and use of the numerical control machine tool is reduced, and meanwhile, the hardware equipment such as a PC and a switch is not required to be arranged, so that the cost can be effectively reduced. In addition, the single-chip microcomputer control system 102 is uniformly adopted to directly collect the state information of the numerical control machine tool, and the state information can be directly transmitted and stored based on a mobile communication network and a TCP/IP network protocol, so that the method can be applied to the state information collection of the numerical control machine tools of different manufacturers, and the flexibility of setting the numerical control machine tools in workshops is improved. The singlechip control system 102 can also control the realization of automatic reconnection of the disconnection of the mobile communication network without losing data.
