Abstract

The invention discloses a wireless sensor network-based monitoring and positioning system for radionuclide-contaminated water and soil. The system comprises positioning and monitoring nodes, a base station node and a comprehensive processing server, wherein the base station node is used for communication with the positioning and monitoring nodes, the comprehensive processing server is connected with the base station node through a wired network, the positioning and monitoring nodes are communicated with the base station node through the ZIGBEE standard, the positioning and monitoring nodes are composed of beacon nodes and non-beacon nodes, and each beacon node comprises a GPS positioning module, a first microprocessor module, a first memory module, a first ZIGBEE module, a first sensor module, a first analog-to-digital conversion module and a first power supply module. The wireless sensor network-based monitoring and positioning system has greatly improved practicality; since the system is based on GPS-ZIGBEE dual-mode positioning technology, platform expansibility is good, a plurality of nodes can be loaded at the same time, and a variety of sensors can be loaded; and the system has the characteristics of low energy consumption, long stand-by time, a small size, light weight, portability and adaptivity to a variety of severe environments.

Description

technical field [0001] The invention belongs to the field of radioactive uranium tailing pond pollution monitoring, and in particular relates to a radionuclide water and soil pollution monitoring and positioning system based on a wireless sensor network. Background technique [0002] The radioactive source can emit rays with strong penetrating power, and has a wide range of applications: in medical treatment, it can irradiate human tumors and kill cancer cells; in agriculture, it can irradiate agricultural products, sterilize and prevent corrosion; in metal industry, it can be used to find welding metals flaws, and carry out industrial flaw detection; measuring instruments such as material level gauges and nuclear scales made of radioactive sources are less affected by environmental factors such as temperature and humidity, and operate reliably; but radioactive sources are also a double-edged sword. Improper operation or storage during the application process may cause accid...
