Variable-frequency pulse terminal radio-frequency anti-metal electronic tag based on a vernier caliper

Abstract

The invention discloses a variable-frequency pulse terminal radio-frequency anti-metal electronic tag based on a vernier caliper. The electronic tag structurally comprises a clamping pincer frame, a nixie tube, a fine thread cap, a vernier plate, a coarse thread wheel, a ruler strip plate, a key position cover plate and a label coupling base. According to the invention, the vernier plate is matched with the label coupling base, and the reserved gap vibration isolation and compression resistance effects are achieved. The snakelike coupling frame can prevent the pressing ruler strip plate from being collided by scanning. An extended reserved space correction effect of the scanning front end is formed. One-time operation of data transverse scanning and recording is achieved. Terminal data areobtained through a simple subtraction step after autonomous programming of the single-chip microcomputer board. During the period, the pressure of the vernier plate is unloaded, and then the snakelike bent pipe structure of the snakelike coupling frame enlarges the single-step double-position scanning area, thereby forming precision adjustment under the housing and vernier measurement static knife edge inclined plane feedback, guaranteeing that the use efficiency of the vernier caliper is not affected by the knife position, and improving the autonomous reading integrity.

Description

technical field [0001] The invention relates to a frequency-variable pulse terminal radio frequency anti-metal electronic label based on a vernier caliper, which belongs to the field of electronic labels. Background technique [0002] Electronic tags are commonly used electronic devices for measuring logistics shelves and logistics box cards. This device is convenient for independent reading and identification of barcodes, and it is convenient for logistics personnel to enter data and load inventory information, realize the effect of organizing logistics big data, and ensure the database of this single product. storage, so that the data system is perfected and flexible. The shortcomings of the current technology that need to be optimized are: [0003] When the vernier caliper measures the accurate value of the reading, the electronic label is set up to facilitate the digital display of the enlarged data, but in the process of signal reception and conversion, there will be a ...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a frequency-variable pulse terminal radio-frequency anti-metal electronic tag based on a vernier caliper, so as to solve the problem of setting up an electronic tag to facilitate digital display of enlarged data when the vernier caliper measures the accurate value. During the conversion process, there will be a displacement difference between the displacement of the scale teeth and the sliding push of the clamping knife close to the scale, which needs to be subtracted to obtain the data. At this time, the electronic tag must first use the coupling structure to slide and scan twice to record the readings respectively, and then display successively. Subtraction to obtain accurate values, this semi-automatic labor-intensive operation, instead delays the measurement time and settlement progress, and causes a load on the electronic label and the vernier plate. Repeated friction and measurement of the weight of the sliding plate will cause the scale to fall off paint and scratches, so that the coupling The scanning deviation increases the subtraction value of the terminal measurement data and affects the final measurement value
