摘要： A Railway Signal Safety Communication Protocol I (RSSP-I) safety communication method based on dual-system synchronization belongs to the technical field of safety communication, and includes: adopting 0×01 for both main machine and standby machine protocol interaction types in a message header of a Real-time Safety Data (RSD) message, and adopting 0×82 for both message types of a main machine and a standby machine; changing data sent by the main machine and the standby machine into a plurality of copies of completely same data by adopting a redundancy technology; and sending the plurality of copies of completely same data to a receiving end by the main machine and the standby machine. According to the present disclosure, reliability and safety of data transmission are improved.

摘要： Provided is a vital digital input dynamic sampling circuit, comprising: a rectifying circuit (10) configured to convert an input signal to a DC signal; a voltage stabilizing circuit (11) connected to the rectifying circuit, and configured to control a voltage amplitude of the DC signal; and a sampling circuit (12) including first and second input terminals (121, 122), and a sampling terminal (123), the first input terminal (121) being configured to receive an input signal, the second input terminal (122) being configured to receive a sampling control signal, and the sampling terminal (123) being configured to acquire a DC signal corresponding to the first input terminal. The present disclosure reduces the probability that signals at the wrong side are misjudged.
