Description
The system resource is open completely, with rich on board resources and very
high expansibility.
LT-8086 training platform adopts INTEL8088(compatible 8086) system, all the system
resources, 8 bit data line, 16 bit address line, read and write control signal are all lead out
and open to the users. The training kit board has rich module resources, please see the
module resources list in detail. Besides, it also provides “experiment module extension”
interface, and offer rich sensor module packages, thus make the single sensor training
platform and microcomputer interface training platform can get rid of the limitations of
separating from the teaching, implement the perfect combination of the current sensor
and microcomputer interface, make our designed microcomputer interface more close to
the actual application and more intelligent.
Standard configured high speed easy used USB communication interface, can online simulation and adjust program
Standard equipped with USB communication interface, can plug and use at will, can
applied for desktop computer and the laptop without serial port, support the operation
Systems of WIN98，WINME，WIN2K，WINXP，WIN7, also can conveniently
switchover to RS232 serial communication interface, through upper software connection,
can implement online simulation, adjusting and developing program
Do not need computer and the convenient and rapid demonstration mode
The system is equipped with management monitoring, in the condition of no PC machine
connection, the system can automatic switchover to off-line management state, the users
can use the 4*6 keyboard at the bottom right corner to call the experiment programs in
the EPROM, can do the experiment off-line, which is convenient for the teacher to verify
and demonstrate during the initial teaching period, at the same enhance the interest and
desire of the student.
Its difficulty is increased gradually, with detail experiment introduction
The experiment difficulty is increased gradually, from simple to complex, make the new
learners can completely master all kinds of complex system and programming design
from beginning unconsciously,
Vivid digital control type innovative training platform
LT-DAQ digital control innovative training platform is to describe the some complex
experiment (such as the four layers elevator control system) by current popular two dimensional animation technology and with the help of PC resources and control system
to simulate the actual object. Through USB interface circuit to implement CPU control to
Virtual controlled object and the both way communication between CPU and virtual
controlled object. This training platform is vivid and with strong operability, can implement
complex close loop control which is greatly improve the student learning interest and
creativity. Comparing with the traditional real object module, it has high cost performance;
do not need the following maintenance and repair, convenient and safety use. At present,
this innovative training platform has 15 typical system experiments.
