Embodiment Construction

[0078] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0079] Such as figure 1 As shown in the micro-grid network structure diagram composed of Bluetooth wireless sensors, the Bluetooth wireless sensor of the present invention can form a micro-grid network with any other Bluetooth devices that conform to the Bluetooth communication specification, and a maximum of 7 Bluetooth wireless sensors can form a sensor network (dynamically changeable) , and form a system together with the host computer for data collection of on-site signals and equipment monitoring.

[0080] Among them, the Bluetooth wireless sensor mainly includes two modules: the sensor module SM and the Bluetooth wireless module BM. The former is mainly used for data acquisition of on-site signals, converting the analog quantities of on-site signals into digital quantities, and completing the conversion and storage of digital quantities. The latter ru...

Abstract

A blue-tooth wireless sensor includes a data collection module, a blue-tooth wireless moule further processing and transmitting data wirelessly, a program control module responsible for data collection, process and data communication with a level device. This device is mainly used in wireless data collection under industrial field control, it can set up connection and carry out data exchange withany device in conformity with blue-tooth wireless sensor stipulations and forms a wireless acess system with the level device by forming networks with multiple sensors to be used in many fields difficult of laying out cables.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a bluetooth wireless sensor based on the bluetooth communication protocol, which belongs to field signal acquisition equipment used in industrial field control and capable of performing wireless data transmission. Background technique [0002] Traditional industrial sites, including various sensors, controllers, instruments, meters and other equipment, use wired communication for data transmission and data collection. If there are more field devices, the connecting cables will also increase proportionally. Over time, more and more cables are scattered all over the place, causing great inconvenience to the operation of the industrial site. Moreover, it is very easy to cause accidents on the industrial site. Secondly, there are a large number of temporary equipment connections in industrial sites. Sensors, instrumentation, and even control networks may be built temporarily and t...
