Embodiment 1

[0064] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is:

[0065] A gateway communication method can realize dynamic configuration of communication modules, can realize free conversion between different communication protocols, and provides one-to-one, one-to-many, and many-to-many data routing modes. Such as figure 1 shown, including:

[0066] Receive network configuration information packets. The network configuration information message includes network path, communication configuration information and identification ID.

[0067] A corresponding configuration module is started according to the network configuration information message, and the configuration module configures a corresponding communication module, and the communication module includes a source communication module and a destination communication module. In this embodiment, a communication module is also created, and the communication module includes a CAN communication mo...

Abstract

The invention discloses a communication method for a multi-functional gateway supporting a TRDP protocol. The communication method comprises the steps that corresponding configuration modules are started according to network configuration information messages, and the configuration modules configure corresponding communication modules; a shared memory module is created, and a shared memory is created for each communication module in the shared memory module; write interfaces and read interfaces are created according to the communication modules; the source communication modules parse receivedvalid data through a protocol and then write the valid data into the shared memories through the write interfaces; and the destination communication modules read the valid data in the shared memoriesthrough the read interfaces. Different message information corresponds different configuration modules, and dynamic configuration of the communication modules can be achieved; and the source communication module can writes the valid data into the shared memory through the write interfaces, and the destination communication modules can read the valid data from the shared memories through the read interfaces, so that free conversion between different communication protocols is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method of a multifunctional gateway supporting the TRDP protocol. Background technique [0002] TCN (Train Communication Network, train communication network) is a data communication network for the transmission, control, detection and diagnosis information of programmable equipment between railway trains and vehicles. In order to transmit information between subsystems of the train, the subsystem and the train network To be able to exchange data between them, protocol conversion must be performed, and the gateway device plays an irreplaceable role. [0003] At present, TCN includes MVB (Multifunction Vehicle Bus, multifunctional vehicle bus) and WTB (WireTrain Bus, twisted train bus), and the maximum transmission rate is 1.5Mbit / s. As the train network transmits more and more data, such transmission The rate obviously cannot meet the needs of train communi...
