Embodiment Construction

[0041] The present invention is further described in conjunction with the following examples.

[0042] see figure 1 , the embodiment of the first aspect of the present invention provides a data transmission method, including:

[0043] The S1 remote server establishes a communication connection with the wireless sensor network module.

[0044]S2 The remote server receives the collected data from the wireless sensor network module. Wherein, the wireless sensor network module includes a converging node and a plurality of sensor nodes arranged in the monitoring area, and the converging node establishes a communication connection with the remote server; initially, the monitoring area is divided into a plurality of sub-areas on average In each sub-area, the sensor node closest to the center of the sub-area is designated as the cluster head. When the network is initialized, each sensor node selects the nearest cluster head to join the cluster; the cluster head is responsible for co...

Abstract

The invention provides a data transmission method, device and system, wherein the method comprises the following steps: a remote server establishes a communication connection with a wireless sensor network module; the remote server receives the collected data from the wireless sensor network module; the remote server compares the received data with the pre-stored standard data to determine whetherthe received data is abnormal; and when the received data is abnormal, the remote server transmits the abnormal data to the predetermined user terminal. The invention, based on the wireless sensor network technology, realizes wireless communication and real-time monitoring of data without wiring, saves manpower and material resources, and can more effectively and more real-time present the data required by the user to the user through the interaction between the remote server and the user terminal.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data transmission method, device and system. Background technique [0002] With the development of science and technology, the early manual monitoring has been basically eliminated. The traditional method is to send people to each monitoring area for monitoring with handheld detection equipment, and enter the acquired data into the relevant system. This monitoring method is inefficient and costly. High, and users cannot obtain the required data in real time. With the development of computer technology and wireless sensor network technology, possible methods and means are provided for wireless monitoring in a large area. A wireless sensor network is a network composed of a large number of wireless sensor nodes in a self-organizing manner. It has the characteristics of high sensor node density, frequent network topology changes, and limited node power, computing power...
