Abstract
The invention discloses a multi-functional RFID tag with a temperature sensor and a humidity sensor. The multi-functional RFID tag is composed of an RFID circuit, an antenna, a temperature sensor, a humidity sensor and a switch device. A control signal output terminal of the RFID circuit is connected with a control signal input terminal of the RFID circuit by the switch device; a signal output terminal of the temperature sensor is connected with a temperature signal input terminal of the RFID circuit; and a signal output terminal of the humidity sensor is connected with a humidity signal input terminal of the RFID circuit. The switch device includes a fuse and a temperature sensitive switch. When an RFID reading-writing device emits a radio frequency signal each time, an induced current is generated in the RFID tag, the fuse is in a conducting or non-conducting state continuously, and the humidity sensor and the temperature sensor works in a forked mode. According to the invention, a problem that the temperature and humidity can not be monitored timely in agricultural greenhouse cultivation can be solved; the plant growth environment information can be obtained timely; and thus the qualities and production of fruits and vegetables can be increased.
Description
Technical field
The present invention relates to for the RFID label tag in greenhouse gardening, particularly relate to for a kind of multi-functional RFID label tag having temperature and humidity sensor concurrently in greenhouse gardening.
Background technology
During greenhouse gardening, there is certain requirement to indoor temperature and humidity, such as plant certain vegetables, the harvest that just can will have under certain humidity and temperature.But in greenhouse gardening, often be all difficult to hold to temperature and humidity, the equipment that neither one is suitable can reflect the change of indoor temperature and humidity timely.
Electronic tag, also known as radio-frequency (RF) identification, is a kind of contactless automatic identification technology.By the radiowaves launched at a distance of several centimetres to several meters distance inner sensors, the information that can store in reading electronic labels, the identity of the article of identification representated by electronic tag, people and utensil.Temperature sensor and humidity sensor are one of the most basic, demand is large sensor types, are widely used in industrial and agricultural production, scientific research and sphere of life.RFID sheet can identify the information of destination object, but it can not obtain the environmental information residing for it, and temperature sensor and humidity sensor can temperature and humidities residing for detection of a target object, but can not identify the information of destination object.
Summary of the invention
Object of the present invention is just a kind of multi-functional RFID label tag having temperature and humidity sensor concurrently be provided for solve the problem in greenhouse gardening.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes RFID circuit, antenna, temperature sensor, humidity sensor and switchgear, the control signal end output terminal of described RFID circuit is connected with the control signal input end of described RFID circuit by described switchgear, the signal output part of described temperature sensor is connected with the temperature signal input of described RFID circuit, and the signal output part of described humidity sensor is connected with the moisture signal input end of described RFID circuit.
Particularly, described switchgear is made up of fuse and temperature responsive switch, the first end of described fuse is connected with the first end of described switchgear and the first end of described temperature responsive switch simultaneously, and the second end of described fuse is connected with the second end of described switchgear and the second end of described temperature responsive switch simultaneously.
Beneficial effect of the present invention is:
The present invention transforms on the basis of existing RFID label tag, add temperature inductor, humidity sensor and switch, formed one improve can the RFID label tag of measuring tempeature and humidity, solving in agricultural greenhouse plantation can not the problem of the deficiency of monitor temperature and humidity in time, the environmental information of timely acquisition plant growth, makes fruits and vegetables increase matter increment; Full extend rfid system function, makes RFID technique have a wide range of applications in agrotechnique simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of RFID label tag of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
The present invention includes RFID circuit 2, antenna 5, temperature sensor 3, humidity sensor 4 and switchgear 1, the control signal end output terminal of RFID circuit 2 is connected with the control signal input end of RFID circuit 2 by switchgear 1, the signal output part of temperature sensor 3 is connected with the temperature signal input of RFID circuit 2, and the signal output part of humidity sensor 4 is connected with the moisture signal input end of RFID circuit 2.Switchgear 1 is made up of fuse 8 and temperature responsive switch 9, the first end of fuse 8 is connected with the first end of switchgear 1 and the first end of temperature responsive switch 9 simultaneously, and the second end of fuse 8 is connected with the second end of switchgear 9 and the second end of temperature responsive switch 9 simultaneously.
As shown in Figure 1: RFID label tag 6 invests on booth parts, RFID label tag 6 RFID circuit 2 that comprises antenna 5 and be connected with switchgear 1.After rfid interrogator 7 pairs of booths send radiofrequency signal, RFID label tag 6 Received signal strength, fuse 8 conducts electricity, temperature responsive switch 9 is in short-circuit condition, RFID circuit 2 is made a response to the received signal, humidity sensor 4 experiences humidity, through RFID label tag 6 information processing, the information of process is passed to rfid interrogator 7; Fuse 8 is non-conductive, and temperature responsive switch 9 works, and temperature inductor 3 experiences temperature, through RFID label tag 6 information processing, the information of process is passed to rfid interrogator 7.Rfid interrogator 7 often launches a radiofrequency signal, all can produce induction current in RFID label tag 6, and such fuse 8 is constantly in conducting and not on-state, humidity sensor 4 and temperature inductor 3 forked working respectively.
