Abstract The title of "guests’ lighting-off system in Nanning TV " derives from the project department
of Nanning TV Station, which refers to the female guests’ lighting-off system in a program of “If
You Are the One” in Jiangsu Satellite TV. However, this thesis puts forward a higher requirement:
making 50 or more female guests on-site participation in the program (there are 24 women on-set at
present in Jiangsu Satellite TV). The increase in the number of controlled lights may cause several
problems if it is under the usual system.
1, the overall communication control gap is much longer;
2, the overall communication system load will be too large;
3, the number of controlled terminals will increase and adjustability is required.
As to these questions, this design will employ the RS485 communication, 5 ~ 15V voltage and
its own hardware address set to resolve such conflicts. Initially, this system is scheduled to utilize
255 terminal points distributed in a more then 2Km bus and make them work simultaneously.
From the macro perspective, the system is going to use the STC12C5A60S2 and
STC89C52RC of MCS-51 core chip as the master and slave core processing chip respectively,
aiming to form a mixed multi-machine system allowing multi-machines to co-process. In this
system, a lower host controls the execution; the hypogyny slave is responsible for the
implementation of the terminal; the epigyny is responsible for sending down the initial parameter
configuration directives and the output manifestation of lighting-off.
This thesis, based on the previous functions, will strictly conform to the practical requirements
for engineering development, and explicitly explore the development procedures of the practical
project and the login of its key technological information from a university student’s perspective. It
is hoped that this article will lay certain foundation in practical exploitation for teachers and
students in university.
