Communication device between modules of expressway robot

The utility model relates to the technical field of communication, in particular to a communication device between expressway robot modules, which is composed of a chassis module A, an LED screen module B and a sensor module C. The chassis module is provided with a 4G module A, the LED screen module B is provided with a 4G module B, the sensor module C is provided with a 4G module C, and the 4G module A, the 4G module B, the 4G module C and the sensor module C are arranged in parallel. And the chassis module A, the LED screen module B and the sensor module C are transferred through mqtt data. Compared with the prior art, the communication device between the expressway robot modules has the advantages that the robot module mqtt data is transferred, the same type of data is transferred, the data processing overhead is not increased, the real-time problem of data communication of each module of the expressway robot is solved, each module of the expressway robot can be used independently through 4Gmqtt, the long-
