Abstract

The utility model provides a node module of a GPS (Global Positioning System) sensor, which is used for outputting geographic information, such as longitude, latitude and elevation, of a geographic position and can be widely applied to the fields of positioning navigation of automobiles, ships and the like, agriculture, traffic and rescue. The node module comprises an ATmegas8L controller (1), a GPS-89 sensor circuit (2), a communication interface connector (3) and a power supply circuit (4). And the node module provided by the utility model utilizes the GPS sensor and a singlechip to realize the output of geographical coordinate information of a geographic position, and has the characteristics of simple structure, low cost, easiness for popularization, and the like.

Description

GPS sensor node module

Technical field

The utility model relates to a kind of GPS sensor node module, adopts 8 8-digit microcontrollers and GPS sensor to realize the geographic coordinate information output in geographic position specifically, can be used for the fields such as location navigation and agricultural, traffic, rescue of automobile, boats and ships etc.

Background technology

Along with the widespread use of information acquisition and intelligence computation technology rapid development and internet and mobile radio communication, technology of Internet of things has obtained application in fields such as industry, agricultural, service sector, environmental protection, traffic.Sensor technology is the basis of Internet of Things; Internet of Things will rely on sensor as data input pin; Through various sensor acquisition or obtain natural various physical quantity, chemistry amount, biomass etc., thereby raising realizes intelligentized decision-making and control to intramundane perception.

Wireless sensor network technology is as a gordian technique in the Internet of Things; The information of various environment or monitoring target in monitoring in real time synergistically, perception and the collection network overlay area; And it is handled; Information after the processing is sent through wireless mode, and sends the observer to the network mode of organizing multi-hop certainly.A kind of as in the wireless sensor network technology of ZigBee technology has characteristics such as cost is low, low in energy consumption, network capacity is big, data transmission is reliable, is of wide application.

Summary of the invention

The utility model technical matters to be solved is, a kind of with low cost, simple in structure, GPS sensor node module of being easy to promote is provided.

The technical scheme that the utility model adopted is: a kind of GPS sensor node module, have controller, and also comprise the GPS-89 sensor circuit that links to each other with controller; The communication interface connector that is used to carry out data transmission and function expansion that links to each other with controller.

Described GPS-89 sensor circuit links to each other through three-way communication interface with controller, realizes the collection and the output of geographic coordinate information.

Described communication interface connector links to each other with common I/O mouth with the serial ports of controller, and the transmission that is used for data perhaps links to each other with the ZigBee gusset plate and carries out function expansion, forms a node in the wireless sensor network.
