A bluetooth one-master multi-slave communication method for a portable multi-parameter health check box

Abstract

The invention discloses a one-master-with-multiple-slave Bluetooth communication method for a portable multi-parameter health examination box and belongs to the field of communication methods. The communication method comprises the following steps that: 1, communication hardware is configured and classification initialization is conducted; 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 are made to enter a pair matching mode; 3, the master equipment Bluetooth module searches for the slave equipment Bluetooth modules and establishes connection 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 in need of connections according to the addresses. The one-master-with-multiple-slave Bluetooth communication method for the portable multi-parameter 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 bluetooth one-master and multiple-slave communication method for a portable multi-parameter health check box, belonging to the field of wireless communication. Background technique [0002] Bluetooth is a radio technology that supports short-distance communication of devices (generally within 10m), which 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 multi-parameter health check box is a kind of medical equipment suitable for on-site use and field operation. There are inspection hosts, various detecti...

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 multi-parameter health check box is a kind of medical equipment suitable for on-site use and field operation. There are inspection hosts, various detection tools, and inspection instruments placed in it. Information sharing is often required between various inspection instruments and inspection hosts. , transmission and storage, 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
