Description
Technical field the invention belongs to the intelligence system field, a kind of intelligent early warning system for field crop pest and disease disasters that relates to technology such as sensor network, gsm wireless communication, intelligence computation, software, database, Internet network of more specifically saying so.
Background technology farmland disease insect pest monitoring and warning process is made up of five links: " the Monitoring Data collection → Monitoring Data transmission → Monitoring Data processing → disaster alarm analysis → information of observing and predicting is issued ".
At these five links, existing a plurality of related invention patent applications, but these related invention owing to narrow application range, be difficult to reasons such as expansion, product cost height, carry out large-scale application in unattended many crops land for growing field crops and have big problem, introduced respectively below.
The sharp patent of invention of having applied for " intelligent monitor system of The greenhouse ecological health " by name of China Agricultural University's Shen assistant on May 15th, 2003, this patent application is open on December 24th, 2003, and application number is 03131063.X.This disclosure of the Invention the intelligent monitor system of a The greenhouse ecological health, the transducer and the supervision crop disease and insect image acquisition process device that comprise the temperature measured in the greenhouse, humidity, each parameter of illumination, each parameter measurement is according to the program of computer in the greenhouse, experience three subsystem processes, they are:
1) under Single-chip Controlling, carry out real-time collection, demonstration, the preservation of each parameter, this is " electronic eyes " monitoring subsystem;
2) data of gathering are passed to the crop expert system knowledge base of being made up of single-chip microcomputer, carry out data analysis, compare, preserve with the desired data of setting, and crop disease and insect is made the control suggestion, this is " brain " intelligent subsystem.
3) after data compare, exceed the suitable growth scope of crop or reach the suitable clockwork spring spare scope of crop regular incidence insect pest or disease and pest surpasses index for control according to temperature, humidity, illumination, promptly in time notify the user in the mode of SMS, this is that " electronics mouth " calls out subsystem.
The intelligent monitor system of this The greenhouse ecological health can be to temperature, the humidity in the energy-saving type plastic booth heliogreenhouse, and illumination and crop disease and insect are monitored automatically, can in time call out when the environmental health of crop runs into crisis, reminds the user to take measures.
Five links of pest and disease monitoring early warning have been finished in this invention really.But this invention designs at warmhouse booth, can't remote monitor land for growing field crops environmental data, only be suitable for single user, nonoculture thing, single expert system, " brain " subsystem wherein is to compare by the desired data with environmental data and expert's setting to draw the disease and pest grade and prevent and treat conclusion, promptly reach a conclusion by a series of judgement, dependence to expertise is strong, can't handle the multiple disease and pest situation in various crop land for growing field crops, disease and pest historical data utilance to various places is low, and extensibility is not strong.
Bao-an District Agriculture Science ﹠ Tech. Spreading Center, Shenzhen City has applied for the patent of invention of " long distance wireless Crop Information feedback and greenhouse agriculture intellectualizing system " by name on February 24th, 2004, this patent application is open on January 5th, 2005, and application number is 200410004716.5.This disclosure of the Invention a kind of long distance wireless Crop Information feedback and greenhouse agriculture intellectualizing system, comprise frequency variable synchronous fertigation machine, feature is also to comprise weather and irrigate control operation system, physiological diagnosis monitoring system, programmable controller and computer.This invention also comprises plant growth situation and ambient conditions Database Systems, cucumber cultivation expert control and consulting system, built-in lightning-protection system and malfunction monitoring and warning system.This invention can all can monitor, control, diagnoses the diagnosis control of the growing environment of the crop in the greenhouse, self upgrowth situation, fertilizer irrigation and disease and pest, carries out remote operation by network.This invention have advanced design, diagnosis accurately, decision science, intelligence program height, controllability is good, practicality is strong, advantage such as powerful, reliable and stable, can be widely used in land for growing field crops water-saving irrigation, agricultural facility cultivation and greenhouse soilless culture system.
