In recent years owing to the development of microprocessor technology, the small size SPC (Stored Program Control) electronic switching system has been widely used.In 1979 a characteristic model machine of 100 line SPC picturephone exchange was developed in Beijing Institute of Posts and Telecommunications. The structure of its hardware and software are all rather simple. It is mainly used as a teaching model.This paper describes the program structure of this exchange, putting emphasis on the project characteristic...
In recent years owing to the development of microprocessor technology, the small size SPC (Stored Program Control) electronic switching system has been widely used.In 1979 a characteristic model machine of 100 line SPC picturephone exchange was developed in Beijing Institute of Posts and Telecommunications. The structure of its hardware and software are all rather simple. It is mainly used as a teaching model.This paper describes the program structure of this exchange, putting emphasis on the project characteristic and the basic structure of call processing program, and provides the major part of the flow chart of call processing program. It can be used as a reference for those who are interested in knowing the basic technology of the software of SPC electronic switching system.
There is an essential distinction between large-scale and small-scale program structures. One of the important research topics of the former area is the consideration of interfaces between different modules. But that is not the case with the latter. The tree structure software, interface modules and the related personnel organizations have been discussed in this paper. Meanwhile, the authors point out that we should consider construction complexity in the definition of program complexity.
This paper describes hardware,software and interfacing circuits of a microcompu-ter control system used for weighing error correction,and coke moisture measurementand compensation in blast furnace burden preparation.Methods of improving reliability and interference suppressing capability have alsobeen suggested.
