The invention provides a turnout transponder message processing method and train control onboard equipment. The turnout transponder message processing method comprises the following steps: receiving a transponder message sent by a transponder, wherein the transponder message includes a transponder ID; determining a transponder message processing mode according to the transponder ID; carrying out a train control processing to the transponder message according to the transponder message processing mode. By using the turnout transponder message processing method and the train control onboard equipment, the train control onboard equipment can carry out the train control processing according to actual situations of train control ground equipment in a turnout area when a train passes through the turnout area. Therefore, initiation of unnecessary train braking can be effectively avoided. Train operation efficiency can be raised under the condition of guaranteeing train operation safety.

The invention discloses a decentralized train route resource negotiation method, which comprises the following steps that: in a decentralized regional network, a pilot train in the current period is selected, and other trains are called following trains; the pilot car receives a dispatching instruction from an operation and dispatching system, generates log entries with corresponding numbers and then copies the log entries into the following car in parallel, when the log entries are applied to a state machine of the pilot car and the pilot car copies the log entries into the following car exceeding a set proportion, the corresponding log entries are called submitted log entries, and the submitted log entries are submitted. The following vehicle sequentially executes the submitted log entries through a state machine of the following vehicle according to the sequence; and each train periodically returns information obtained by executing the corresponding log entry to the operation and dispatching ...

The invention provides an arbitration system of vehicle-mounted train control equipment, and belongs to the technical field of the safety control of railways and solving the problem of incapability of ensuring the correctness and safety of the output quantities of the safety computer because calculated results are only arbitrated, but output quantities of respective passageways of a computer are not arbitrated in the traditional redundant safety computer system. The arbitration system comprises an arbitration module used for arbitrating the output quantities of two computers in the redundant safety computer system respectively and outputting the output quantities when the output quantities of the two computers are the same, wherein the output quantities of the two computers comprise the output quantity of an I/O (Input/Output) port and the output quantity of a communication port. In the invention, as the output quantities of the I/O port and the communication port of the computers are arbitrated ...
