Abstract

The invention provides a method for dynamically constructing a virtual instrument, and relates to the technical field of virtual instruments and meters. The method comprises a process of establishinga network structure information table and a process of establishing a virtual instrument and meter in each instrument and meter, and is characterized in that the instrument and meter are accessed to anetwork and sends own equipment information to the network in a broadcast manner; The instrument receives the broadcasted equipment information and generates the network structure information table according to the received equipment information; One instrument in the network receives an instruction which is input by an external system and is used for constructing the virtual instrument; And theinstrument and meter retrieves in the structure information table according to the instruction to obtain the data node corresponding to the instruction, and constructs the virtual instrument and meter. According to the invention, a new complex multifunctional instrument can be conveniently constructed, new measurement requirements of an external system are met without too much cost, and flexible expansion can be carried out according to requirements.
