Method and device for locating wireless fetal monitoring probes in set area

摘要

The invention relates to a method and device for locating wireless fetal monitoring probes in a set area. The method comprises the following steps: instructions are sent via a plurality of wireless base stations to instruct the wireless probes in the action scopes of the wireless base stations to send base station signal intensity data tables; the wireless probes search all receivable base station signals, establish the base station signal intensity data tables; operations are carried out based on the received current base station signal intensity data tables and base station signal intensity data tables of reference points to obtain a distance reference table; the position of one with the smallest distance value is selected to be regarded as the current position of the corresponding probe. The method and the device have the benefits of quickly locating each wireless probe and avoiding loss of monitoring data.

1. A method for locating wireless fetal monitoring probes in a set area, comprising the following steps:
A) a data management center sends instructions via a plurality of wireless base stations arranged at different positions in the set area to instruct the wireless fetal monitoring probes in the action scopes of the wireless base stations to send base station signal intensity data tables of received base station signals; B) the wireless fetal monitoring probes search all receivable signals of the base stations after receiving the instructions, quantize the intensities of the received signals of the base stations, establish base station signal intensity data tables in which the signal intensities of the base stations are arranged according to the serial numbers of the base stations, and send the base station signal intensity data tables to the data management center via the base station of which the received signal intensity is the largest; and C) operations are carried out based on each received current base station signal intensity data table sent by the corresponding wireless fetal monitoring probe and reference point base station signal intensity data tables which are obtained in advance and comprise base station signal intensities at a plurality of reference points in the set area to obtain a distance reference table expressing distance between the current position of the wireless fetal monitoring probe and each reference point; and the position of one reference point with the smallest distance value is selected to be regarded as the current position of the wireless fetal monitoring probe.
