Data communication method, main equipment and system

Abstract

The invention discloses a data communication method, main equipment and a system. The method comprises the following steps: initiating a communication signal to an interface in an interface module; under the condition that the response information of the slave device accessed to the interface is received, the physical ID information of the interface is added into an online queue, and the probability that the interface in the online queue is subsequently initiated with a communication signal is higher than that of the interface in an idle queue; receiving data information transmitted by slave equipment in the interface; the data communication main equipment comprises a communication signal initiating unit, an online interface recognition unit and a data information receiving unit which areused for realizing the steps of the method. According to the method and the system, the communication network for simultaneous communication between the plurality of slave devices and the master device can be established, the communication network is high in communication efficiency, the working state of the newly accessed slave device can be identified as soon as possible, the data information ofthe on-line state slave device can be efficiently transmitted, and the physical realization and connection are simple and convenient.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data communication method, device and system. Background technique [0002] With the development of technology, especially the application and promotion of telemetry technology in the field of drones, more and more sensors with different functions and types are applied to drones. Therefore, the communication between a wide variety of sensors and receivers has become increasingly complex, and information such as the parameters of the UAV site collected by sensors is very important for the control of UAVs, so the data transmission between sensors and receivers is very important. appears to be very important. [0003] At present, this part mainly uses the traditional wireless communication method, and there are still common problems such as weak reliability, complex interface, and no support for hot plugging. [0004] For the above problems, no effective solution h...
