A multi-master and multi-slave Bluetooth communication method for a portable health check box

Abstract

The invention discloses a multiple-master-with-multiple-slave Bluetooth communication method for a portable health examination box. The communication method comprises the following steps that: 1, mater communication equipment and slave communication equipment are designated and preset; 2, a master equipment Bluetooth module and slave equipment Bluetooth modules are powered up simultaneously and the master equipment Bluetooth module and the slave equipment Bluetooth modules enter a pair matching mode; 3, the master equipment Bluetooth module searches for the slave equipment Bluetooth modules and connects with the slave equipment Bluetooth modules; 4, the connection in the step 3 is interrupted and a far-end Bluetooth address is obtained; 5, the step 3 and the step 4 are repeated till Bluetooth addresses of all the slave equipment Bluetooth modules are obtained and backuped; 6, the master equipment Bluetooth module is connected with the slave equipment Bluetooth modules according to the addresses; 7, the steps from 1 to 6 are repeated, the master equipment Bluetooth module is set into a slave equipment Bluetooth module, a new master equipment Bluetooth module is designated till the master equipment Bluetooth module designated for each time acquires and saves corresponding addresses of the slave equipment Bluetooth modules in need of connections, and the multiple-master-with-multiple-slave Bluetooth communication mode is achieved. The multiple-master-with-multiple-slave Bluetooth communication method for the portable health examination box has the advantages that the usage is convenient, accurate and efficient, and no connecting wire is needed.

Description

technical field [0001] The invention relates to a multi-master and multi-slave bluetooth communication method for a portable health check integrated box, belonging to the field of wireless communication. Background technique [0002] Since Bluetooth technology is a radio technology that supports short-distance communication of devices (generally within 10m), it can include wireless information exchange between mobile phones, PDAs, wireless headsets, notebook computers and related peripherals. The traditional Bluetooth technology mostly adopts a distributed network structure, fast frequency hopping and short packet technology, and supports point-to-point communication, that is, one device to one device, but it cannot be completed when it needs to transmit data with multiple devices at the same time. [0003] At present, the portable health check all-in-one box is a kind of medical equipment suitable for on-site use and field operation. There are various detection tools and in...

Problems solved by technology

Traditional bluetooth technology mostly adopts distributed network structure, fast frequency hopping and short packet technology, and supports point-to-point communication, that is, one device to one device, but it cannot be completed when it needs to transmit data with multiple devices at the same time

[0003] At present, the portable health check all-in-one box is a kind of medical equipment suitable for on-site use and field operation. There are various detection tools and inspection instruments placed in it. Information sharing, transmission and communication are often required between various inspection instruments or detection tools. Save, the connection between communication interfaces is very inconvenient, and Bluetooth transmission can only be transmitted one-to-one, which is extremely inefficient and error-prone
