SYSTEM FOR CONTROLLING MULTI-POINT-TEMPERATURE BASED ON CONTROLLER AREA NETWORK

摘要

PURPOSE: A CAN communication-based multi-contact point temperature control system is provided to secure control performance and a stable output value in a sudden case by combining PID control technology with purge technology. CONSTITUTION: A host module(100) provides an HMI(Human Machine Interface) for providing a control unit between a user and a machine. A contact point control module(200) controls contact point temperature corresponding to each process by using a control command of the host module. A plurality of contact point control modules are installed in a CAN bus(300) to performs communication with the host module. The CAN bus connects the host module with the contact point control modules. A display unit(400) displays states of the contact point control modules and the CAN bus.
