Method and device for broadcasting monitoring data of Bluetooth wristband

Abstract

The invention discloses a method and device for broadcasting a Bluetooth wristband. The method includes classifying the monitoring data of the Bluetooth wristband to obtain a data type ID; when the data type ID is between 0X0000 and 0X7FFF, compressing the monitoring data to obtain a Bluetooth BLE broadcast packet, wherein 2 lower bytes of the Bluetooth BLE broadcast packet are actual values, and 2 higher bytes are 2 lower bytes of a UNIX-like timestamp at the moment when the actual values are acquired; and filling the current monitoring data to the Bluetooth BLE broadcast packet in turn among the monitoring data type 0, the value 0 of the monitoring data, the monitoring data type 1 and the value 1 of the monitoring data, broadcasting after encryption and verification, and receiving by Bluetooth BLE receiving device. The method for broadcasting the monitoring data of the Bluetooth wristband can efficiently transmit current state data of the Bluetooth wristband, while the Bluetooth wristband location information and current data are effectively obtained, the capacity of system access is improved, data flow between a device and the BLE receiving device is reduced, and repetitive operation is avoided.

Description

technical field [0001] The invention relates to the field of monitoring of medical bluetooth wristbands, in particular to a method and device for broadcasting monitoring data of bluetooth wristbands. Background technique [0002] With the popularity of the Internet of Things, the use of Bluetooth bracelets is becoming more and more widespread, especially in the medical industry. The broadcast mechanism and method adopted by the traditional Bluetooth bracelet cannot meet the actual needs, such as: the action of operating the Bluetooth bracelet and the current change data of the Bluetooth bracelet will not be broadcast through BLE, which brings great benefits to the use of the Bluetooth bracelet. Large limitations, can not play a greater role in the medical industry. At the same time, the communication method between the Bluetooth bracelet and the Bluetooth master device needs to use the mode of establishing a connection and one-to-one communication. The communication efficie...

AI Technical Summary

Problems solved by technology

The broadcast mechanism and method adopted by the traditional Bluetooth bracelet cannot meet the actual needs, such as: the action of operating the Bluetooth bracelet and the change data of the current Bluetooth bracelet will not be broadcasted through BLE, which brings great difficulties to the use of the Bluetooth bracelet. Big limitations, unable to play a bigger role in the medical industry

At the same time, the communication method between the Bluetooth bracelet and the Bluetooth master device needs to adopt the connection establishment and one-to-one communication mode. The communication efficiency between the two parties is very low, and the bandwidth is relatively large and the capacity is low.

In one-to-one mode, within a certain period of time, only two Bluetooth devices can communicate, and it is not possible to simultaneously send / broadcast data from multiple bracelets

[0003] Ordinary Bluetooth BLE broadcast packets can generally only load 31 bytes, of which 1 byte is the length, and 1 byte is the Bluetooth broadcast type, plus UUID, the actual current information of the Bluetooth bracelet that can be transmitted is very limited, such as Ibeacon The base station only transmits 2 to 3 pieces of information, and the use is limited
