Module expansion method based on intelligent measurement terminal

The invention discloses a module expansion method based on an intelligent measurement terminal. The module expansion method comprises the following steps that 1, the intelligent measurement terminal can establish reliable connection with idle equipment through the Ethernet or in a wireless mode; step 2, idle equipment controls and manages each module through an application manager app; 3, an application manager app of the intelligent measurement terminal inquires whether the equipment in reliable connection has idle modules or not, and the idle modules needing to be used are bound; step 4, the application manager app of the idle device continuously receives the control instruction of the binder, and forwards the interaction content of the idle module; 5, the intelligent measurement terminal receives reply information from the idle module, and module expansion of the intelligent measurement terminal on the idle device is achieved. The method is established on two existing devices, extra device investment is no
