Gprs-based Farmland Wireless Data Acquisition System Methods And Technology

Produce the technical development along with the agriculture, will beg to farmland of stingy wait the data( include the temperature, degree of humidity, rainfall... etc.) to carry on the solid hour of monitor, so need a credibility, availably solid hour to collect the system, the credibility and the usefulness that the exaltation data collect. The research work and results of this treatis mainly have:From the system structure and carry out the way up detailed introduced to make use of the lead-in data to collect the technique of RTU and GPRS lead-in datas to deliver the technique to combine together, the lead-in data solid hour that carried out the farmland collect and concrete method that data deliver.Carried on to collect the system and deliver the design of the system in this treatis. Use according to a machine of data collect the technique design to collect the ability system enough the credibility complete the temperature, degree of humidity, rainfall, light to shine on four kinds of datas to collect, having already can satisfy the farmland to collect the request in these four kinds of basic datas. Collect the system spreads the feeling machine technique, apply the ITU- BUS, will single line agreement collect of data deliver to collect to control the mold piece. Adopt the lead-in of GPRS delivers the method correspondence method simple, and safe credibility.Pass to practice to prove this kind of system structure that collects the system and GPRSs to deliver the system according to a machine, is the farmland data to collect the best way currently.
