Embodiment Construction

[0019] The present invention will be further described below with reference to the drawings and specific embodiments. It should be understood that the specific implementation described here is only used to explain the present invention, and not to limit the present invention.

[0020] Such as figure 1 Shown.

[0021] A data reliability transmission method of wireless medical equipment based on error retransmission includes the following steps:

[0022] S101: First, a reverse link is introduced between the central processing unit of the Bluetooth piconet composed of medical equipment in each family and each slave device;

[0023] S102: Then the sending end of the medical device encodes the information data for error detection, such as cyclic redundancy coding (CRC), and sends the encoded data to the central processing unit;

[0024] S103: Finally, the central processor feeds back the information of whether the data frame is correctly received at the receiving end to the sending end, an...

Abstract

The invention relates to a data reliability transmission method for wireless medical devices based on error retransmission. The data reliability transmission method is characterized in that a reverse link is introduced between the central processing unit of a Bluetooth piconet formed by medical devices in various families and each slave device; the sending end of the medical device performs error-detection coding on information data, such as cyclic redundancy coding (CRC), and sends the coded data to the central processing unit; the central processing unit feeds back information whether data frames are correctly received at a receiving end to the sending end; and the sending end selects a data frame to be sent in the next frame according to an appointed strategy. By means of the data reliability transmission method disclosed by the invention, the partial data loss problem when multiple devices in the piconet send data to the central processing unit at the same time can be effectively solved; and thus, the communication quality of the medical devices in the Bluetooth piconet can be ensured.

Description

Technical field [0001] The invention relates to a wireless communication technology, in particular to a wireless medical equipment data reliable transmission control technology, in particular to a wireless medical equipment data reliability transmission method based on error retransmission. Background technique [0002] Smart elderly care, also known as Smart home care, is a newly popular concept of elderly care. The intelligent elderly care system is based on the Internet of Things technology. By implanting electronic chip devices in home elderly care equipment such as wrist sphygmomanometers, watch-type GPS locators, weight scales, blood glucose meters, etc., it can remotely monitor the daily life status of the elderly, while also being able to know Their activity trajectory. The intelligent elderly care system directly transmits the monitored data to the electronic health file of the elderly in the contracted medical unit. Once the data is abnormal, the system will automatica...
