Introduction In the field of automation, there are devices that cannot be operated manually, such as high-pressure gates and corrosive liquid valves. Typically, we use computer software to control these devices through a combination of PC-based host software and a microcontroller. Project Requirements Design a controller with four relays that can be controlled via software … Read more
With the development of computer technology, railway interlocking has been upgraded, leading to the emergence of computer interlocking. The difference between computer interlocking devices and the 6502 electrical interlocking is the addition of a driver acquisition circuit, which delegates the interlocking computation tasks to the computer. Regarding the driver circuit, the figure shows the station … Read more
