Problems solved by technology

[0005] For the data collection scenario of laying out base stations along the line and solving sensor nodes through relay devices, it is also inevitable that the network transmission bottleneck will cause the sensor network to be paralyzed
In practical applications, due to the long train tracks and wide coverage, the number of sensor nodes that need to be deployed is huge. Therefore, if the sensor network is directly connected to the base stations deployed along the line, a large number of relay devices are required, and the intermediate nodes of the cellular module and the sensor module are equipped at the same time. Following the high cost of equipment, the overall networking cost is too high, but the data collection efficiency has not been greatly improved accordingly
In addition, the coverage area of ​​the sensor network is small, and it may be located between the base stations along the line, which is far away from the base stations at both ends, so the demand for direct connection to the base station is not practical for sensor nodes with limited energy consumption

Embodiment 1

[0022] In the high-speed railway environment, the real-time monitoring data of the dedicated wireless sensor network deployed along the way for monitoring the status of the driving track and environmental monitoring can be efficiently collected through the high-speed train. Since the sensor is an energy-limited device, it only relies on its own battery to maintain energy supply. Therefore, for wireless sensor networks, in the process of effectively reporting and monitoring data communication, effectively reducing energy consumption and the active cycle of sensor nodes are important for maintaining long-term It is very important for the reliable operation of wireless sensor network. The sensor network mainly includes three aspects: sensing, communication, computing (hardware, software, algorithm). The key technologies include wireless database technology, such as the query used in wireless sensor networks, and network technologies used to communicate with other sensors, especia...

Embodiment 2

[0033] Such as Figure 2~4 As shown, the high-speed train has the function of communicating with the wireless sensor network. Antenna devices for activating / deactivating wireless sensor nodes are respectively deployed at the front and rear of the vehicle, and the specific deployment locations can be separately placed at the bottom and both sides of the compartment. In addition, a certain number of data receiving devices are deployed on both sides and bottom of the train carriage, which is equivalent to the data terminal equipment in the traditional sensor network. When such a high-speed train passes through a wireless sensor detection network deployed around the track, its method for collecting data from ground wireless sensors includes the following steps:

[0034] Step 1: When the high-speed train is running, the activation antenna device installed at the front of the train sends an activation command to the wireless sensor network located in front of the train.

Abstract

The invention relates to a method and a device for collecting ground wireless sensor data by high-speed rail motor cars. The method comprises the following steps: 1) an activation antenna device arranged at the head of an motor car sends activation orders for the wireless sensor network positioned in the front of the motor car; 2) the wireless sensor network sends the motor car rail status information or environmental monitor information to a data receiving device arranged at a motor car body; 3) the data receiving device sends the received motor car rail status information or the environmental monitor information to a train main control table for data integration, and then sends the data after integration to a background processing server through an external communication interface on the train; and 4) a deactivation antenna device arranged at the tail of the high-speed rail motor car deactivates the wireless sensor network by which passes. Compared with the prior art, the interlinking problem of the sensor network in remote areas is solved by the method and device provided by the invention, the sensor network spread at each place is connected to the external network by utilizing the high-speed rail motor car as a data carrier.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and a device for collecting ground wireless sensor data from high-speed trains. Background technique [0002] In traditional wireless sensor network applications, sensor nodes in wireless sensor networks transmit detection data to target data terminals through multi-hop data transmission. Usually, the target data terminal is equipped with a communication link with an external network for transmitting data to a background data analysis server through the network. Data terminal equipment is often a special device different from ordinary sensor nodes, because it needs to bear more communication traffic and must have sufficient energy supply. Energy supply is the main factor restricting the deployment of wireless sensor networks, so efficient routing and MAC mechanisms are often used to optimize the data transmission of sensor networks to achieve the purpose of...
