Embodiment Construction
[0039] In order to ensure the high-speed and effective transmission of complex control system and measurement system data, the data transmission system must support high data transmission rate, low bit error rate and high real-time performance. high demands.
[0040] The data transmission topology structure diagram of the present invention is as follows image 3 shown. Depend on image 3 It can be seen from the figure that the high-speed synchronous serial data transmission method based on one master and multiple slaves designed by the present invention includes a master A and multiple slaves B. Host A shares a ground wire and a signal wire with each slave for high-speed data transmission.
[0041] The host computer A sends a collection command signal, which is encoded by a programmable logic device and then transmitted, and the corresponding slave machine accepts the command and responds according to the host computer command, specifically based on a high-speed synchronous...
