Abstract: A temporary speed restriction safe management method for a multi-mode train control system. The method comprises: step 101, issuing a temporary speed restriction setting instruction by means of a line network dispatching system; step 102, performing a validity check on a set temporary speed restriction, and setting a first mark-drawing up after the check is successful; step 103 setting a second mark-verification; step 104, feeding a verification state or verification failure of the set temporary speed restriction back to the dispatcher; step 105, an auxiliary dispatcher issuing an execution instruction for the verified temporary speed restriction; step 106, determining that the temporary speed restriction is successfully executed; step 107, feeding an execution state or execution failure of the temporary speed restriction back to the dispatcher; and step 108, sending the temporary speed restriction to a train of a corresponding system that passes through a speed restriction zone.

Abstract: The present invention relates to an FSK and LAN protocol conversion apparatus for a rail transit signal system, wherein the apparatus includes: a control instruction sending module (TC); a device state receiving module (TK); a data validity check module (VD) connected with the TC and the TK respectively; a first Ethernet redundant communication module (LAN A) connected with the VD; a second Ethernet redundant communication module (LAN B) connected with the VD; and a system configuration and maintenance module (MAN) connected with the above modules respectively. Compared with the prior art, the present invention has the advantage of implementing network access with a new ATS system of a control center on the basis of an original system, with minimized capital investment and maximized utilization of the existing station device.

Abstract: The present invention relates to a marshalled train management method, apparatus, device and medium, the method including: S1: identifying, by a CC, train formation; S2: identifying, by a trackside ZC, coupling marshalling information; S3: when the coupling marshalling information or the train formation is valid, calculating, by the trackside ZC, a valid movement authorization for the marshalled train; S4: checking, by the CC, a currently applied marshalled train parameter state thereof; if the coupling marshalling information or the train formation is valid, setting the formed train parameter state to be available; and if the state is available and the valid movement authorization is received, safely controlling the train to run; S5: verifying, by the CC, an availability state of the marshalled train parameter state in real time according to the coupling marshalling information or the train formation; and S6: when the coupling state of the marshalled train changes during online coupling or dis-marshalling, re-performing the calculation and verification steps of the CC and the trackside ZC. Compared with the prior art, the present invention has advantages of high safety, high reliability, high availability, etc.
