Abstract

The invention discloses a multi-protocol temperature controller for an aluminum oxide suspension roaster and a control method. The controller is composed of an industrial-grade processor MCU, a Profibus DP interface module, an Ethernet module, an RS485 interface module, a CAN module, two paths of 0-10V AO modules, four paths of DO modules, an EEPROM, a dial switch and an LED indicating lamp. Communication and data exchange between the temperature controller and the communication board card are achieved through a PROFIBUS-DP protocol, an RS485 MODBUS-RTU protocol, an MODBUS-TCP/IP protocol and a CAN protocol, a temperature control operation program based on the fuzzy control theory is stored in a storage of the MCU, parameters for aluminum oxide suspension roasting temperature control are provided, fuzzy control over the temperature is automatically achieved, and control signals are output. The controller provides various communication protocols, makes control decisions according to the fuzzy set and the fuzzy logic, has great potential in the aspect of solving complex control problems, can dynamically adapt to changes of the external environment, and carries out control adjustment in real time.

Description

technical field [0001] The invention relates to the technical field of automatic temperature control, in particular to a multi-protocol temperature controller and control method for an alumina suspension roasting furnace. Background technique [0002] In the alumina roasting furnace used in the metallurgical process, the temperature of the alumina suspension roasting furnace is an important parameter of the roasting operation, and its control level not only affects the energy consumption of the product, but also determines the quality of the product. [0003] At present, in the industrial production of alumina suspension roaster, the temperature control of alumina suspension roaster is mostly in the manual operation stage, which requires the operator to monitor and adjust frequently. Larger, no longer meet the needs of industrial production. Therefore, there is an urgent need for a multi-protocol temperature controller for the alumina suspension roaster, which replaces the ...
