Method for collecting data of wireless sensor network on basis of high-speed train

Abstract

The invention discloses a method for collecting data of a wireless sensor network on the basis of a high-speed train, which comprises the following steps of: arranging sensor nodes on a bridge or a tunnel far away from a city for acquiring structural health monitoring data of buildings; determining a coverage range, a sensor number and a transmission range of the wireless sensor network and using one sensor node in each cluster as a fusion node of the cluster; determining a data fusion mode of the network, a data transmission mode and a data fusion mode of aggregation nodes; determining the number of vehicle-mounted signal transceivers on the train, arrangement positions of the vehicle-mounted signal transceivers and running parameters of the train; determining data transmission modes of the aggregation nodes and the vehicle-mounted signal transceivers; reconstructing lost data in the broadcasting process; and reconstructing a data stream, then carrying out data fusion and uploading the fused data to a data center so as to complete data collection. According to the invention, power consumption of the sensor nodes is reduced and service life of the network is prolonged.

Description

technical field [0001] The present invention relates to a data collection method, in particular to a wireless sensor network data collection method, and more specifically to a high-speed train-based wireless sensor network data collection method. Background technique [0002] The rapid development of Micro-Electro-Mechanical System (Micro-Electro-Mechanism System, MEMS), System on Chip (SOC, System on Chip), wireless communication and low-power embedded technology has given birth to Wireless Sensor Networks (WSNs) , and brought about a revolution in information perception with its low power consumption, low cost, distributed and self-organizing characteristics. The wireless sensor network is composed of a large number of miniature sensor nodes deployed in the monitoring area. It is a multi-hop self-organizing network system formed by wireless communication. Its purpose is to cooperatively perceive, collect and process the perceived objects in the network coverage area. info...

But in their works, they only focus on collecting complete sensor readings, and do not consider the mobility of sink nodes.

[0008] After searching, it was found that the Chinese patent application number is: 200710019928.4, and the name is: a wireless sensor network data collection method based on multi-agent negotiation. This technology provides a data collection method for a wireless sensor network based on a static sink node, but this technology No proof of applicability for mobile aggregation nodes; Chinese patent application number: 200710304581.8, titled: Sensor Data Collection System in Urban Environment, which proposes a data collection for wireless sensor networks based on mobile vehicle on-board information transceivers method, but this technology does not consider the scenario when the sensor node is far away from the city
