Abstract: The present invention provides a selective data transmission method and a system based on a central monitoring system. The selective data transmission method includes a wireless sensor, wherein the wireless sensor executes the following steps of: A. collecting data; B. sending the data to a designated receiving end; C. selecting a receiving end according to an instruction, and taking the receiving end as the designated receiving end; and D. establishing a wireless connection with the designated receiving end. The present invention has the advantageous effects that the method and the system realize selective data transmission through transmitting the data to a selected receiving end, which not only can be applied to the field of medical monitoring, but also can be applied to such fields as security prevention, data backup and the like; working nodes can be switched.

Abstract: 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.
