Abstract

The invention discloses an advanced algorithm intelligent PID process controller. The controller comprises a terminal wiring unit, a power supply system circuit, a single-chip microcomputer control circuit, an input signal sampling circuit, a control output circuit, a transmission output circuit, a communication interface circuit, an alarm relay control circuit and a digital DIO circuit. The powersupply system circuit, the single-chip microcomputer control circuit, the input signal sampling circuit, the control output circuit, the transmission output circuit, the communication interface circuit, the alarm relay control circuit and the digital DIO circuit are all electrically connected with the terminal wiring unit. A power supply, input stage and output stage isolation design is adopted,so that the safety is high; a modular design is adopted, so that the integration level is high, and various complex control occasions can be adapted; a program segment working mode is achieved, and complex process curve control can be achieved.

Description

technical field [0001] The invention relates to the technical field of industrial automation measurement control, in particular to an advanced algorithm intelligent PID process controller. Background technique [0002] Most of the current industrial PID controllers are compatible with relatively few types of input signals. For signals such as nonlinear thermocouples and thermal resistances, analog curve fitting technology is used to achieve low precision and cumbersome setting of range parameters. The controller does not have a good replacement on site when the input signal changes, and the parameter setting method is relatively limited, so it is very inconvenient to replace it on site. And there is only one input, the loop mode is relatively simple, and there is no remote control setting SV (set value) function. Most DCS systems require remote SV setting. Without the second input measurement circuit, the function expansion cannot be realized, and the mathematical operatio...
