Embodiment 1

[0037] The invention discloses a calibration block, an electronic scale and an automatic calibration method of the electronic scale using them.

[0038]

[0039] See attached figure 1 , by attached figure 1 Visible, the calibration block consists of:

[0040] The weight block 11 is a solid with stable shape, at least one plane, and its quality does not change due to ambient temperature and humidity;

[0041] The RFID chip 12 is built into the weight block 11 and records the weight of the calibration block. The weight of the calibration block is the sum of the weight of the weight block 11 and the RFID chip 12 .

[0042] An electronic scale, including a mechanical part and a circuit part, a sensor transmits the change information of the mechanical part caused by the measured object, that is, the weight information of the measured object, to the circuit part, see the attached figure 1 It can be seen that the circuit part includes:

[0043] RFID read-write device 21, ...

Abstract

The invention discloses a calibration block, an electronic scale and an automatic calibration method. The calibration block includes a weight block and an RFID chip, and the electronic scale includes an RFID read-write device, a processing unit, a display screen, and a communication module; the RFID chip in the calibration block records The electronic scale can measure the actual weight of the calibration block, and the RFID read-write device of the electronic scale can read the standard weight of the calibration block recorded by the RFID chip of the calibration block. And the standard weight automatically calibrates the weighing calculation formula. Applying the present invention, on-site management personnel can complete the calibration of the electronic scale through the calibration block. There is no human interference factor in the calibration process, and the data in the calibration process is automatically recorded and automatically sent to the central server. The measurement management organization can monitor the electronic scale in real time. Weighing accuracy. Therefore, the present invention solves the problem that the electronic scale cannot be automatically calibrated in time, and the measurement management department cannot efficiently monitor the calibration result.

Description

technical field [0001] The invention belongs to the field of intelligent control, relates to a calibration block and an electronic scale, and also relates to an automatic calibration method using the calibration block and the electronic scale. Background technique [0002] The electronic scale includes a mechanical part and a circuit part. When the measured object is weighed, the relevant parts of the mechanical part will change. The change information is collected through the sensor, and the information is transmitted to the circuit part for processing, and then the measured object is obtained. the weight of. [0003] As a weighing tool, electronic scales are widely used. In supermarkets and various vegetable markets, a large number of electronic scales are used to complete the weighing work of selling goods. Even if the metrology management department conducts a metrological test on the public electronic scale once a year, it is a massive task and it is almost impossible ...
