A two-dimension code identification module of the hand-held machine is used to scan or log a bar code, a site safety tool is inquired. An infrared thermodetector of the hand-held machine is used to measure temperatures of an instrument and equipment and the temperatures are submitted to the server so as to display. By using the structure in the invention, effective safety supervise can be reached, effective safety management and control is realized and controlled performance, controllability and controlling performance of safety production are realized too.
