Abstract: In o rder to convenience the operation, surveillance and debugging of the aerial railway contro lled by the PLC, this paper in
troduces a design of a monito r circuit system constituted by the SCM and LCD screen, using the C p rogramm ing language p lete
the p rogram. This circuit has m ade a ess in w atching the running of the aerial railway, w ith the qualities of simp le circuit struc
ture, fine p roperties, low co st and p ractical value.
Key words: aerial railway; monito r circuit; LCD screen; Chinese characters lattice; buffer address
