Embodiment Construction

[0047] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] In order to solve the problems of the prior art, the present invention provides a high-reliability data transmission method applied to emergency treatment, using a data collection method of compressed sensing, which is very suitable for nodes that transmit data through wireless links; Figure 1-Figure 2 As shown, assume that in the emergency communication environment, there are N wireless transmission nodes and one sink node. The data acquisition node is usually powered by a battery, and its own energy is extremely limited. The energy supply of the sink node is relatively sufficient, and it is responsible for receiving N wireless transmission nodes. The data sent, the specific data transmission is shown as figur...

Abstract

The invention belongs to the technical field of emergency communication, and in particular relates to a high-reliability data transmission method applied to emergency treatment. The method includes: collecting original data; collecting compressed data containing abnormal values; reconstructing compressed data containing abnormal values; compared with the prior art, the present invention has the following beneficial effects: (1) less energy consumption: due to the emergency treatment environment The data in the system has the characteristics of dynamics and complexity, and each sampling needs to collect the values ​​of two sensors at the same time. The data collection method proposed by the present invention only needs to collect one value each time, thus reducing the amount of data transmission in the network and reducing the energy consumption in the network. (2) High accuracy of data reconstruction: The application scenarios of emergency wireless transmission nodes are complex and usually contain unpredictable environmental noise. The invention adopts a high-reliability data transmission method applied to emergency treatment, uses the principle of compressed sensing to collect data, and can realize accurate reconstruction of data.

Description

technical field [0001] The invention belongs to the technical field of emergency communication, and in particular relates to a high-reliability data transmission method applied to emergency treatment. Background technique [0002] In all fields of social life, various emergencies occur anytime and anywhere. For emergencies, relevant departments should understand the situation of emergencies in a timely manner, formulate emergency response plans, and effectively deal with them, so as to reduce the incidence of accidents and the loss of life and property. Due to the unpredictable situation of emergency emergencies, the data of emergencies are dynamic, immediacy and complex, and it is required to carry out reliable wireless transmission and collection of various emergency data collected so that they can reflect the reality of emergency events. The situation, so that each department can deal with it accordingly. Usually, highly integrated smart sensors are deployed on a large ...
