Abstract

The invention discloses a Zigbee protocol based proportion integration differentiation (PID) parameter tuning controller. The controller comprises a PID parameter tuning controller host and at least one wireless input/output node for connecting a field testing device, wherein the PID parameter tuning controller host comprises a shell, an antenna connected with the shell, a wireless receiving module fixed in the shell, a mainboard and a power supply module; the wireless input/output node comprises an input module, an output module, a central processing unit (CPU) module and a radio frequency module; and the PID parameter tuning controller host is connected with the wireless input/output node through a Zigbee protocol based wireless signal. The PID parameter tuning controller has good network coverage through miniature networking design, is convenient to assemble and use, and is suitable for signal collection and measurement in industrial automation.

Description

technical field [0001] The invention relates to the technical field of signal acquisition and measurement in civil and industrial automation, in particular to a PID parameter tuning controller based on the Zigbee protocol Background technique [0002] In automation engineering practice, the most widely used regulator control law is proportional (P), integral (I), differential (D) control, referred to as PID control. It has been nearly 80 years since the PID controller came out. It has become one of the main technologies of industrial control because of its simple structure, good stability, reliable operation and convenient adjustment. The PID controller is based on the error of the system, using proportional, integral, and differential to calculate the control parameters for control. [0003] The parameter tuning of PID controller is the core content of control system design. It determines the size of the proportional coefficient, integral time and differential time of the...
