Problems solved by technology
Since the radio station communication is an open communication, there will be communication collisions between multiple wireless reconnection groups, but the wireless reconnection workshop in the same marshalling group does not have a communication scheduling mechanism, which reduces the efficiency of wireless communication in the marshalling station as a whole , the frame loss of the data frame is serious

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] The main principle of the wireless communication method for wireless reconnected locomotives based on radio stations in the present invention is to solve the problem by adopting a wireless data air relay mechanism between wireless reconnected locomotives in the same formation. At the same time, for multiple marshalling machine workshops, the interval time of the rotation training is mainly used. The interval time can be adjusted according to the speed of the car and the change of the master car command, and the communication between multiple wireless reconnection groups can be solved by increasing the overall communication idle time. Collision issues without affecting the quality of communication. Through the air relay mechanism of the present invention combined with periodic rotation training, the problem of wireless data fram...

The invention provides a wireless communication method of wireless reconnection locomotives based on a wireless radio. Transmission is carried out among the wireless reconnection locomotives in the same group through an alley-oop mechanism, namely, when a main locomotive sends an instruction data frame, the instruction data frame is forwarded to a second auxiliary locomotive through a first auxiliary locomotive connected with the main locomotive, then is forwarded to a third auxiliary locomotive through the second auxiliary locomotive, and is sequentially transmitted in the same way; when the auxiliary locomotives are used for transmitting a state data response frame, state data are sequentially transmitted to the main locomotive from the last auxiliary locomotive in a relay mode, the last auxiliary locomotive transmits the state data to a penultimate auxiliary locomotive connected with the last auxiliary locomotive, the penultimate auxiliary locomotive transmits the state data of the last auxiliary locomotive and the state data of the penultimate auxiliary locomotive to the antepenultimate auxiliary locomotive, the antepenultimate auxiliary locomotive transmits the state data of the last auxiliary locomotive, the state data of the penultimate auxiliary locomotive and the state data of the antepenultimate auxiliary locomotive to the fourth auxiliary locomotive from the last, and in the same way, the state data of the auxiliary locomotives are forwarded to the main locomotive. The method has the advantages that the principle is simple, safety is good, communication efficiency is high, and reliability of wireless communication is good.
Description
technical field [0001] The invention mainly relates to the technical field of locomotive reconnection, in particular to a wireless communication method for wireless reconnection locomotives based on radio stations. Background technique [0002] At present, wireless reconnection and heavy load technology has been applied in a certain range. In the existing reconnection of locomotives, some practitioners have proposed wireless communication to complete the communication between reconnected locomotives, and wireless communication is mainly completed through radio stations. As more and more locomotives are put into wireless reconnection operation, there may be multiple wireless reconnection communication groups in a marshalling yard or operation line. Since the radio station communication is an open communication, there will be communication collisions between multiple wireless reconnection groups, but the wireless reconnection workshop in the same marshalling group does not ha...
