Problems solved by technology

[0002] In the communication of a multi-sensor system, due to the large number of sensors, only one set of data receivers is generally set up, especially when wireless communication is used for data transmission, each independent sensor is in a disordered state of autonomously sending data, and the data receiver Unable to process a large amount of received data in a short period of time, resulting in data accumulation problems, which will eventually seriously affect the real-time requirements of the system

Abstract

The embodiment of the invention provides a communication method and device of a multi-sensor system. The method comprises the steps that a data receiving end broadcasts a first instruction to multiple groups of sensors, the first instruction is used for notifying the multiple groups of sensors to report equipment states to the data receiving end, the multiple groups of sensors send second instructions to the data receiving end, and the second instructions are used for the data receiving end to report the equipment states; after the data receiving end confirms that the second instructions sent by all the sensors are received, third instructions are sent to the multiple sets of sensors, the third instructions are used for notifying the multiple sets of sensors to send sensor data, and after the multiple sets of sensors receive the third instructions, the sensor data are sent to the data receiving end in sequence; and after the data receiving end receives the sensor data sent by all the sensors, the sensor data are integrated to generate the sensor synchronous data packet, so that the problem of data processing delay of the receiving end caused by accumulation of data sent by multiple ends in a wireless communication environment is avoided, and the real-time performance of the whole system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sensor communication, in particular to a communication method and device for a multi-sensor system. Background technique [0002] In the communication of a multi-sensor system, due to the large number of sensors, only one set of data receivers is generally set up, especially when wireless communication is used for data transmission, each independent sensor is in a disordered state of autonomously sending data, and the data receiver It is impossible to process a large amount of received data in a short period of time, resulting in the problem of data accumulation, which will eventually seriously affect the real-time requirements of the system. Contents of the invention [0003] In view of the above problems, embodiments of the present invention are proposed to provide a communication method for a multi-sensor system and a corresponding communication device for a multi-sensor system that overcome the abov...
