A method for data transmission by a wireless sensor network and a medical system

Abstract

The invention provides a method and a device for transferring data through a wireless sensor, and a remote access medical treatment system, wherein the method comprises gaining and transferring required first data waiting transmission to a monitoring unit and other detecting units, feeding back information for receiving the first data, judging and analyzing whether the detecting units for transferring the data receives feedback information, discarding the first data if not, otherwise analyzing the feedback information and discarding the first data if all the feedback information is failure information. If all the feedback information is successful information fed back by the monitoring unit, the data waiting transmission is re-gained. If the feedback information is successful information transferred by at least one other detecting unit, a first preset rule is chosen to transfer the newly detected required data waiting transmission and the first data to the monitoring unit. The method for transferring data through a wireless sensor can guarantee the data have high reliability and low network delay during the process of transferring real-time data.

Description

technical field [0001] The invention relates to the technical field of wireless network data transmission, in particular, to a method for transmitting data through a wireless sensor, a device for transmitting data through a wireless sensor, and a remote access medical system. Background technique [0002] With the rapid development of wireless communication technology, the application range of wireless network is becoming wider and wider; especially the research and development of applying wireless network technology to telemedicine system has produced wireless sensor network in telemedicine system, the wireless sensor network Combining various advanced technologies such as sensors, wireless communications, and computers, it provides patients with uninterrupted monitoring and early warning of medical indicators, thereby ensuring that medical institutions and guardians can grasp patient information in real time and improve medical security. [0003] The wireless sensor networ...

Problems solved by technology

[0004] The problem in the above transmission process is: the waiting stop ARQ mode will keep trying to retransmit after the transmission fails, which will cause the subsequent data to be transmitted to fail to transmit, and real-time data transmission cannot be performed.

[0005] That is to say, the sensor network used in the medical system, because the vital sign data detected by it will change significantly in a short period of time, so the above wireless sensor network cannot be used. The main disadvantage is that the medical data needs to be transmitted in real time Otherwise, real-time monitoring cannot be carried out; if simply adopting the waiting stop ARQ, since there are multiple sensor detection units that need to transmit data in the network, it will cause objective network delay. Unable to monitor the physical condition of critically ill patients in real time
