Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 As shown, the wireless medical device interference suppression method based on synchronous state monitoring provided by the implementation of the present invention includes the following steps:

[0021] S101: First, multiple medical devices in the same family are connected through Bluetooth to form an independent Bluetooth piconet, and the data is transmitted to the central processor, and the central processor allocates 10 to the main device in the Bluetooth piconet of each family Bit random sequence, corresponding to the timer length;

[0022] S102: Then after the timer timing is over, the master device and the slave device of the Bluetooth piconet enter the synch...

Abstract

The invention discloses a wireless medical equipment interference suppression method based on synchronous status monitoring. The wireless medical equipment interference suppression method based on synchronous status monitoring is characterized in that a plurality of medical equipments of the same household are used to form an independent Bluetooth piconet by using a Bluetooth technology, and a 10-bit stochastic sequence is allocated to the master equipment of the Bluetooth piconet, and is corresponding to length of a timer; after the timing of the timer is ended, the master equipment and the slave equipment of the Bluetooth piconet are switched from a connection status to a synchronous status in a time period Ts, and the master equipment and the salve equipment are used to monitor data packets in a preset frequency band in the above mentioned time period Ts; when the data packets are monitored by the master equipment and the slave equipment, the synchronous status is ended, and a local clock is updated, and then a new synchronous status is maintained; when the master equipment and the slave equipment cannot monitor the data packets, the own data packet is transmitted by the master equipment, after the monitoring time period Ts is up, and the synchronous status is disconnected, and the timer is reset. A problem of same frequency interferences between Bluetooth piconets is effectively suppressed, and the communication quality of the medical equipments in the various Bluetooth piconets is guaranteed.

Description

technical field [0001] The invention relates to a wireless communication technology, in particular to an interference suppression technology of a wireless medical device using bluetooth communication, in particular to a method for suppressing interference of a wireless medical device based on synchronous state monitoring. Background technique [0002] Smart old-age care, also known as smart home care, is a newly popular concept of old-age care. The smart elderly care system is based on the Internet of Things technology. By implanting electronic chip devices in home care equipment such as wrist blood pressure monitors, watch GPS locators, scales, and blood glucose meters, it can remotely monitor the daily life status of the elderly, and at the same time know the trajectory of their activities. The smart elderly care system directly transmits the monitored data to the electronic health records of the elderly in the agreed medical unit. Once the data is abnormal, the system wi...
