Computers help то control train traffic

An automatic train operation system is being developed in our country. It will make possible to control and regulate train traffic on all railways. This system is being formed on the basis of computer centres which exist on each of the country's railway lines.The purpose of the traffic control system based on electronics is to make easier the work of traffic controllers who direct the movement of trains on the most intensivelines.

The computer will give the controller the full information on the conditions on the line, model all the processes on the route and advise him what he should do to improve the situation. The computer will advise the drivers with which speed they should drive trains on each sector of the, route. The computer system will help train gatherers in their work. It is only now, in the computer age, that it has become possible to choose the necessary variants of train formation automatically. The new method will double the speed of train processing and make the work of railway-men easier. In the future it is planned to automate train driving as well.

NEW TECHNOLOGY EXHIBITION

The “New Technology Exhibition” is devoted to economic and social developments. Its exhibits show efforts to improve the quality and efficiency of the region production. A large section of the exhibition demonstrates electronics.

The most impressive of the exhibits are robots. They can cut metals, drill holes, compute and teach. All robots are very much things of thepresent.

A multipurpose lathe-robot is specially interesting in that it can “ask questions”. An engineer showed how it works. He pressed a key which has the mark “Thread cutting”. And “Thread pitch?” immediately appeared on the video display screen. The engineer pressed another key with the mark “I”. Another question came on: “Thread length?” The robot has to get all the answers to all its questions before it goes to work.

Another exhibit is a robot which is to operate some metallurgical processes. Before it starts working its operator must take him by "hand" and go through all the programme. The robot memorizes the instructions and then is able to do everything by itself and without any mistakes. Its memory can hold as many as 70 programmes.

Practically all the equipment on display serves to improve the productivity. The exhibition programme provides for high increase in production of technologically perfect, top-quality and efficient types of machinery.
