Embodiment Construction

[0031] A Bluetooth-based multi-point data collection method and device provided by the present invention will be described below with reference to the accompanying drawings.

[0032] When developing devices based on Bluetooth interconnection, because Bluetooth is a point-to-point connection, it is often difficult to connect several slave devices to the master device at the same time. Although Bluetooth also supports point-to-multipoint connections (broadcast mode), it only supports up to 7 slave devices, and the real-time performance of information interaction is not good, and collisions often occur. On the basis of a pair of Bluetooth master-slave devices, the present invention transmits data of several (not limited to 7) functional modules to the opposite end under the premise of ensuring real-time performance and non-collision by adding a data acquisition control module.

[0033] On the basis of a pair of bluetooth transceiver modules, the invention uses the control module ...

Abstract

The invention provides a Bluetooth based multipoint data acquisition device. The Bluetooth based multipoint data acquisition device comprises a voltage stabilization module, a control module, a plurality of clutch modules, a plurality of interface conversion modules, a plurality of functional modules and a Bluetooth module, wherein the voltage stabilization module, the interface conversion modules and the Bluetooth module are connected with the control module respectively, and each functional module is connected with one interface conversion module correspondingly; each interface conversion module is connected with the control module by one clutch module; the control module is used for generating time sequence of an acquisition board, packing and unpacking data and monitoring the operating state of the acquisition board; the clutch module is used for switching on / off the interface conversion modules and the functional modules; the interface conversion module is used for converting data type; and the functional module is used for acquiring functional data. The Bluetooth based multipoint data acquisition device overcomes the defects of Bluetooth point-to-point requirement and poor real-time performance, and can conveniently and rapidly achieve equipment integration.

Description

technical field [0001] The invention is applied to various consumer electronics, vehicle-mounted equipment, surveying and mapping instruments, and industrial equipment, and specifically relates to a Bluetooth-based multi-point data collection device and method. Background technique [0002] Bluetooth is a wireless technology standard that enables short-range data exchange between fixed and mobile devices and personal area networks in buildings. Bluetooth technology was originally created by telecommunications giant Ericsson in 1994 as an alternative to RS232 data lines. [0003] The transmission distance of Bluetooth is 10cm to 10m. If the power is increased or some peripherals are added, the transmission distance of 100m can be achieved. TDMA is 0.625μs per time slot, and the baseband coincides with a rate of 1Mb / s. Bluetooth supports 64kb / s real-time voice transmission and data transmission, using a globally unified 48-bit device identification code. Because Bluetooth u...
