The utility model relates to a passive RFID temperature label's advantage is: low in production cost not only, long service life receives service environment restriction degree low moreover.
Description
Technical field:
The utility model relates to technical field of RFID, and particularly not only production cost is low for one, and long service life, by the passive RFID temperature label that environment for use restriction degree is low.
Background technology:
The develop rapidly of wireless communication technology, embedded technology and sensing technology, promotes the progressively ripe of technology of Internet of things.Sensor is that Internet of Things is the most basic, the equipment of the bottom, plays the vital role of recognition object, Information Monitoring.RFID (RadioFrequencyIdentification) technology, also known as radio frequency identification, is a kind of wireless communication technology, can sets up the communication between sensor and radio network gateway by RFID label chip.
Temperature sensor is one of sensor type that is the most basic, that have the call, is widely used in industrial and agricultural production, scientific research and sphere of life.RFID label chip can identify the information of destination object, but it can not obtain the environmental information residing for it, and temperature sensor can temperature residing for detection of a target object, RFID label chip and temperature sensor being combined can full extend rfid system function, and RFID technique is had a wide range of applications in the field such as the manufacturing, the management of Cold Chain Logistics chain of medical treatment, product.Therefore, being integrated with the RFID label chip of temperature sensor, i.e. RFID temperature label, becoming the research object of many mechanisms, is also one of the main trend and challenge of RFID technique of future generation development.
The active power supply mode of the many employings of existing RFID temperature label (i.e. built-in power) are powered to the tag body of its inside and temperature sensor, this just not only increases the production cost of RFID temperature sensor label, and makes the serviceable life of RFID temperature sensor label and environment for use have severely restricts.
Utility model content:
The technical problems to be solved in the utility model is, not only production cost is low to provide one, and long service life, by the passive RFID temperature label that environment for use restriction degree is low.
Technical solution of the present utility model is, a kind of passive RFID temperature label with following structure is provided, it comprises chip, wherein, passive RFID temperature label also comprises wireless power supply module and for the external antenna with the wireless connections of tag readable degree equipment, chip comprises temperature sensor district, analog to digital converter, Based Intelligent Control district and memory block, and external antenna, wireless power supply module, temperature sensor district, analog to digital converter, Based Intelligent Control district and memory block connect successively.
After adopting above structure, compared with prior art, the beneficial effects of the utility model are: when the utility model uses, as long as label is placed oneself in the midst of in the environment of electromagnetic field, just can utilize the radio-frequency (RF) energy in external antenna induction field, change into the electric energy that can utilize for label again, because the utility model is without the need to built-in power, therefore, not only effectively can reduce the production cost of label, and easy to use, and the life-span is long, its serviceable life is without the need to the restricted life-span on built-in power, lower by environment for use restriction degree.
Improve as one, a kind of passive RFID temperature label described in the utility model, wherein, external antenna is provided with energy storage components and parts.Energy storage components and parts can be used for reserve power, thus auxiliary external antenna can work better.
Accompanying drawing illustrates:
Fig. 1 be a kind of passive RFID temperature label of the utility model and tag readable degree equipment connection time principle of work block scheme.
Embodiment:
Below in conjunction with the drawings and specific embodiments, a kind of passive RFID temperature label of the utility model is described further:
As shown in Figure 1, a kind of passive RFID temperature label of the utility model comprises chip 1, wireless power supply module 3 and for the external antenna 2 with tag readable degree equipment 8 wireless connections.Chip 1 comprises temperature sensor district 4, analog to digital converter 5, Based Intelligent Control district 6 and memory block 7.External antenna 2, wireless power supply module 3, temperature sensor district 4, analog to digital converter 5, Based Intelligent Control district 6 and memory block 7 connect successively.Meanwhile, external antenna 2 is also provided with energy storage components and parts 9, these energy storage components and parts 9 are the inductance or resonant capacitance.
In the utility model, the effect of external antenna 2 is, for wireless connections read write line and tag readable degree equipment 8 with produce electric energy; The effect of wireless power supply module 3 is, the radio frequency electromagnetic for being sensed by external antenna 2 is supplied to temperature sensing district 4 after converting electric current to; The effect in temperature sensing district 4 is, for testing environment temperature, and ambient temperature data signal feedback is arrived Based Intelligent Control district 6 via analog to digital converter 5; The effect in Based Intelligent Control district 6 is, for the work of control store and temperature sensor, and has and provides clock signal, control other RFID functions such as each module cooperative work; The effect of memory block 7 is, for storing the data-signal that Based Intelligent Control district 6 sends over, being sent in Based Intelligent Control district 6 by the data-signal of its storage inside simultaneously and processing, and meeting the needs of other RFID needs memory functions.
The principle of work of a kind of passive RFID temperature label of the utility model is: external antenna 2 is connected with tag readable degree equipment 8 such as read write line by radio connection, when tag readable degree equipment 8 reads label, label is just in an elect magnetic field, external antenna 2 will radio-frequency (RF) energy in induction field, the radio-frequency (RF) energy that external antenna 2 senses will to convert to this electric power supply after electric energy to temperature sensing district 4 by wireless power supply module 3, after temperature sensing district 4 obtains enough energy excitations, digital signal amount is changed into by analog to digital converter 5, via Based Intelligent Control 6 district, data are stored in storage area again, after label receives these data, by oneself certain segment data, such as ID, temperature data, for self-defining data etc., after coding, warp is by external antenna outgoi8ng data, finally turn back to read write line
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
