The utility model for achieving the above object, the technical scheme of taking is: a kind of buckle-type intelligent electronic label based on the passive thermometric chip of SAW, comprise label shell, helical antenna), pcb board, SAW temperature sensor, label base, it is characterized in that: described label shell is docking together and is formed by buckle by label shell I and label shell II; Described label base is square, identical with the ground plane size of pcb board bottom surface; The number of turns on described helical antenna top is 2.5 circles, and the bottom being integrated with helical antenna is standing upright point; Described SAW temperature sensor is welded on pcb board, described helical antenna passes through standing upright means of spot welds on pcb board, the ground plane of described label base and pcb board bottom surface welds together, the above-mentioned whole intelligent electronic label forming is arranged in label shell, and its pcb board is arranged in the groove in label shell I and label shell II.
The beneficial effect that the utility model produces is: in configuration aspects, obtain significant improvement, helical antenna after the utility model optimal design is lower than the section of helical antenna of the prior art before optimizing, the Miniaturization Design target that has realized label, is greatly improved in performance.In order to make user convenient attractive in appearance, whole label shell mechanism is designed to buckle form, and label shell adopts the material of insulation high-temperature-resistant to make, and can reduce design cost, and can not produce large impact to the performance of helical antenna.Helical antenna adopts stainless steel material to make, and design cost reduces, and the helical structure form of design can effectively reduce integrally-built size, and certain height is arranged at bottom, has improved the radiation efficiency of antenna, has reduced the impact of pcb board on helical antenna.
Label base be take brass and is made as material, and outside scribbles one deck tin, facilitates the welding of label base and pcb board ground plane.Whole system only needs label shell to be fixed all structures, without any fixation means.
SAW temperature sensor in this structure is positioned at the inside of total, unless whole label is destroyed, can guarantee so the safety of SAW temperature sensor, has further guaranteed the information security of system.
Aspect principle, the utility model is optimized rear screw antenna and is adopted the form of bottom standpoint to be connected with pcb board, and certain height is arranged at bottom, thereby has improved the radiation efficiency of antenna, has reduced the impact of pcb board on helical antenna.
The utility model has been realized the double resonance structure of helical antenna and microstrip antenna, and helical antenna and microstrip antenna be at same point feed, thereby makes the matching effect between antenna and chip better, and the energy loss of label reduces.
In a word, the utility model is for the passive temp measuring system of SAW, reduced in all its bearings the energy loss of label, increased echo perdurability, have the advantages such as heat conduction is fast, attractive in appearance, convenient, practical, volume is little, section is low, measurement result is accurate, the utility model can be used for the association areas such as warehousing management, logistic track, aviation parcel, automatic control.
