Sintering blast furnace system based on AT90CAN128
single-chip microcomputer ------ Signal acquisition
Abstract
Sintering blast furnace system is relying on regulation to control the
conveyor speed into the charge of a variety of materials, to complete a
variety of clinker ratio. It can change all kinds of physical quantities of
the industrial site (analog signals) into electrical signals through
sensors, and then, after A/D sample is converted to digitalvalue, to
store(information), process, display or printin a computer or system . The
entire system is make up of information collection, PID control and CAN bus
communication , achieveing its main functions, it also can display
information such as a given flow, the actual flow and its error, find out
hidden dangerandremoveitearly,further improve the reliability of the
system.Our design is mainly directed against part of the design of signal
acquisition.
The system is based on AT90CAN128single-chip microcomputer as the core
components of a simple data acquisition system. The main components of the
system are: AT90CAN128、ULN2803、VFD、CS5523、LED and so on。AT90CAN128 is a
low-power CMOS 8-bit microprocessors, which functions usedfor our system to
provide the conditions to achieve the design.
This system is not only to do single-channel signal acquisition, but
also on the cycle of multi-channel signal acquisition, even up to 4-way
acquisition. Traffic signals can be collected, but can also signals to the
