| Abstract: | A kind of design of two unit standby multiplex switch signal acquisition system using GAL is given. In the system, two microcontrollers realize outer 485 communication with the host computer, maintain the same work states by inner communication. Special designed input channel and software arithmetic for jitter's elimination simplify the circuit, and make the action sequence resolution to be 1ms. The usage of GAL simplifies the circuit further, reduces the costs, and improves the stability and security. |
