Problems solved by technology
[0004] At present, there are only a few signal manufacturers at home and abroad who can provide a complete set of rail transit signaling system equipment, and the equipment standards of each signaling system are completely different, and because the current signaling system involves many subsystems, each subsystem It is more difficult to open the interface for interconnection and intercommunication, so there is greater resistance to the interconnection and intercommunication of various subsystems between different signal system suppliers

Embodiment Construction
[0029] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0030] The invention provides a data communication method, which is used in the train answering system, such as figure 1 As shown, in this method, when receiving the message sent by the train control equipment to the ground answering equipment, the processing flow of the on-board answering equipment includes:
[0031] Step 101, converting the data message from the train control equipment into a protocol format that the ground response equipment can recognize.
[0032] Step 102, encode the data message after protocol conversion.
[0033] Step 103, sending the encoded data message to the ground response device.
[0034] Correspondingly, when receiving the ...

The invention provides a data transmission method and answering equipment. In the method, when a data message is received from train control equipment, the following steps are executed: the data message from the rain control equipment is converted to a protocol format that can be recognized by ground answering equipment; the data message which completes protocol conversion is encoded; and the encoded data message is sent to the ground answering equipment. When a data message is received from the ground answering equipment, the following steps are executed: the data message is decoded; the decoded data message is converted to a protocol format that can be recognized by the train control equipment; and the data message that completes protocol conversion is sent to the train control equipment. By adoption of the data communication method and the answering equipment provided by the invention, interconnection and interworking between train control equipment and a ground responder which are provided by different manufacturers can be realized, and the utilization rate of resources is improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method and a response device. Background technique [0002] With the development of urban rail transit in China, it is shifting from the traditional single-line construction to multi-line parallel construction, forming a network rail transit pattern development, in which the signal system is a key system to ensure the safety and efficiency of urban rail transit. It becomes the key to affect the overall operation effect of the urban rail transit system. [0003] In order to meet the needs of rail transit network construction in various places, to improve the overall efficiency and benefits of rail transit, and to improve the consistency of urban rail transit signal systems, the voice of the industry to realize the interconnection of different lines in the same city or lines between different cities From the point of view of the signal system, interconnec...
