The linear hall sensor node module that has positioning function

Technical field

The utility model relates to a kind of linear hall sensor node module that has positioning function; Adopt 8 8-digit microcontrollers, linear hall sensor and GPS locating module to detect the magnetic field on every side under the accurate locus specifically; Thereby realize the measurement of position and angle indirectly, be used for the automatic control of commercial production or life.

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.

The english abbreviation of range-finding navigation/GPS (Navigation Satellite Timing And Ranging/Global Positioning System) was called for short " GPS " when GPS (Global Positioning System) was the satellite survey.This system is to be the radio-navigation positioning system on basis with the satellite; Have navigation, location and the function regularly of totipotency (land, ocean, aerospace), global, round-the-clock, continuity and real-time, can be provided accurate three-dimensional coordinate, speed and the time for all types of user.GPS equipment can provide spatial positional information accurately, and GPS technology is combined with sensor technology, technology of Internet of things, when obtaining the information of same that sensor exports, obtains spatial positional information synchronously, thereby helps the popularization of technology of Internet of things.

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, linear hall sensor node module that has positioning function of being easy to promote is provided.

The technical scheme that the utility model adopted is: a kind of linear hall sensor node module that has positioning function, have controller, and also comprise the magnetic field detection Acquisition Circuit that links to each other with controller; The GPS locating module that is used to provide accurate locus 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.
