An underground pipe network wireless monitoring positioning system

Abstract

The invention discloses a wireless monitoring positioning system applicable to the field of underground pipe network application. The wireless monitoring positioning system is composes of unknown nodes, beacon nodes, Sink nodes, a host computer, etc. The invention discloses a monitoring node positioning method targeting at a wireless self-organizing network, i.e., a progressive incremental type distance measuring positioning algorithm based on an on-line optimization training relation function, and a process of continuous correction of positioning results through the adoption of a plurality of methods. The invention also discloses an sudden-onset disaster accident source positioning method targeting at underground pipe network application, and the sudden-onset disaster accident source positioning method the comprises a time difference method, a state curve method, a multiparameter combination method, etc., and a plurality of methods are adopted to carry out positioning correction, so that positioning with relatively high precision can be realized. The invention also discloses an energy saving optimization method for a realization process of the above positioning method. Through the adoption of the positioning method of the present invention, functions such as underground pipe network automation intelligentized monitoring early warning and sudden-onset disaster highly efficient reliable positioning can be realized, and the positioning method is also advantaged by being accurate in data, being timely and highly efficiently, being low in energy consumption and low in cost, etc.
