Abstract
The invention provides a kind of rfid interrogator for agricultural product information management, the power supply management module, memory module, Keysheet module, Network Interface Module, LCD MODULE and the wireless radio frequency modules that comprise control module and be connected respectively with control module; Described wireless radio frequency modules is for reading RFID label tag and the agricultural product information in label being stored to described memory module, described Keysheet module, for receiving extraneous input, is extracted the information in described memory module and to be shown by described LCD MODULE or described Network Interface Module carries out wireless transmission.Present invention accomplishes the requirement to the collection of front end RF ID label data, process, communication aspects in agricultural product application process; Stable and reliable operation, read-write, data transmission all can meet the demands, and greatly improve the monitoring ability of agricultural management, circulation, sales level and food security.
Description
Technical field
The present invention relates to a kind of rfid interrogator for agricultural product information management, belong to IT application to agriculture technical field.
Background technology
In recent years, food security crisis frequently occurs, and has had a strong impact on the healthy of people.For strengthening food safety Regulation, the supervision of overall process must be carried out to the production of product, circulation.Advantages such as RFID label tag is contactless with it, memory capacity is large, reusable and become important product identification and means of tracking.Along with Food Inspection quarantine system increasingly stringent and consumer wish the information understanding more agricultural product itself, some agricultural product supplier and relevant enterprise start to use RFID technique in the agricultural product production and operation, because the reliability of RFID technique, wide, the low cost and other advantages of conforming have played great function at numerous areas, but as how more low cost effectively, accurately read RFID information and become key affect RFID and apply on agricultural product are produced.Current domestic agriculture aspect exists that read write line kind is few, insufficiency face, interface is simple, price is high, do not have the problems such as independent intellectual property right, can not meet the requirement of IT application to agriculture, limits the Development of IT Application in Agriculture of country.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the invention provides a kind of rfid interrogator for agricultural product information management, high, the Internet Transmission of read-write success ratio is reliable, effectively compensate for that current read-write device data processing method is unreasonable, complicated operation, interface simple and be difficult to the shortcomings such as popularization.
Technical scheme: the rfid interrogator for agricultural product information management of the present invention, the power supply management module, memory module, Keysheet module, Network Interface Module, LCD MODULE and the wireless radio frequency modules that comprise control module and be connected respectively with control module; Described wireless radio frequency modules is for reading RFID label tag and the agricultural product information in label being stored to described memory module, described Keysheet module, for receiving extraneous input, is extracted the information in described memory module and to be shown by described LCD MODULE or described Network Interface Module carries out wireless transmission.
Further, described control module adopts C8051F120 to be main control chip; C8051F120 is low in energy consumption, have kernel at a high speed, and enough RAM and program storage, can meet the requirement of system data processing power and program code amount.
Further, the described wireless radio frequency modules antenna that comprises MFRC530 radio frequency chip, the self-maintained circuit be connected with MFRC530 radio frequency chip and be connected with MFRC530 radio frequency chip through low-pass filter circuit.In the communication of MFRC530 radio frequency chip and RFID label tag, send the Miller coding that signal is 100% modulation distortion, Received signal strength is the Manchester coding of 10% modulation.Send signal to be sent out in the form of an electromagnetic wave by antenna, Received signal strength delivers to RX pin through antenna-matching circuit, and the modulation and demodulation of signal are all processed by the setting of internal proprietary circuit according to register.
Further, described power supply management module comprises charging management chip, step-down chip, low voltage difference voltage stabilizing chip, boost chip, lithium battery; Described step-down chip by after external power source transformation gained voltage step-down through described low voltage difference voltage stabilizing chip convert to low voltage difference voltage stabilizing, simultaneously through described charging management chip to described lithium cell charging, low voltage difference voltage stabilizing obtains booster voltage through described boost chip, and low voltage difference voltage stabilizing, booster voltage all export after described charging management chip.Power supply management module can adopt external power source and lithium battery combination to power, and ensures power supply effect.
Beneficial effect: the rfid interrogator for agricultural product information management provided by the invention, can be used for the links such as agricultural product production, processing, circulation, meets the requirement to the collection of front end RF ID label data, process, communication aspects in agricultural product application process; Stable and reliable operation, read-write, data transmission all can meet the demands, and greatly improve the monitoring ability of agricultural management, circulation, sales level and food security; Overall cost is lower, is particularly suitable for producing at the agricultural product that cost sensitivity coefficient is high and using in monitoring.
