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

Embodiment Construction

[0078] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0079] refer to figure 1 , showing a flow chart of the steps of Embodiment 1 of a communication method for a multi-sensor system of the present invention, which may specifically include the following steps:

[0080] Step 101, the data receiving end broadcasts a first instruction to multiple groups of sensors, where the first instruction is used to notify the multiple groups of sensors to report the device status to the data receiving end;

[0081] The data receiving end broadcasts a first instruction to multiple groups of sensors, so as to notify each sensor to report the device state to the data receiving end, and the device state is a report device ready state.

[0082] Specifically, the command format of the first command is...

Abstract

Embodiments of the present invention provide a communication method and device for a multi-sensor system. The method includes: the data receiving end broadcasts a first instruction to multiple groups of sensors, the first instruction is used to notify the multiple groups of sensors to report the device status to the data receiving end, and the multiple groups of sensors respectively send second instructions to the data receiving end, the second instruction It is used for the data receiving end to report the status of the device. When the data receiving end confirms that it has received the second instruction sent by all sensors, it sends a third instruction to multiple groups of sensors. The third instruction is used to notify multiple groups of sensors to send sensor data. Multiple groups of sensors After receiving the third instruction, the sensor data is sent to the data receiving end in sequence. After the data receiving end receives the sensor data sent by all the sensors, it integrates the sensor data to generate a sensor synchronization data packet, thereby avoiding multi-terminal transmission in the wireless communication environment. The accumulation of data leads to the problem of data processing delay at the receiving end, which greatly improves the real-time performance of the overall system.

Description

technical field [0001] The present 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 the multi-sensor system, due to the large number of sensors, only one set of data receivers is generally set, 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 is in a disordered state. The inability to process a large amount of data received in a short time leads to the problem of data accumulation, which will eventually seriously affect the real-time requirements of the system. SUMMARY OF THE INVENTION [0003] In view of the above problems, embodiments of the present invention are proposed to provide a multi-sensor system communication method and a corresponding multi-sensor system communication device that overcome the ab...
