Embodiment Construction

[0065] System composition and working principle:

[0066] See figure 1 , The system is mainly composed of four parts: background computer (upper computer), communication circuit, foreground single-chip computer (lower computer) and memory (electronic label).

[0067] Its workflow is:

[0068] (1) Input of sensor parameters. The PC enters the "electronic label management system" environment, receives the sensor parameter data entered by the keyboard, and stores the data in the database. Complete the input function of sensor parameters.

[0069] (2) PC and MCU serial communication. The conversion between RS-232 level and TTL level is realized through the MAX232 level converter in the communication circuit, and the communication data transmission format is consistent through the self-defined communication protocol, and the communication task between the PC and the single-chip computer is completed.

[0070] (3) Data reading and writing of the memory. Use I between the single-chip mi...

Abstract

This invention relates to an electronic label management system for a kind of chording sensors, which uses storages as electronic labels to solidify sensor numbers and related parameters in the storage, then puts the storages in the sensor, even though the wrapped labels are lost or worn out, numbers and parameters can still be read out from electronic labels stored in a handheld device so as to solve the technological problems in application, in which, single-chip processor is includes to communicate with the background PC unit in series and reads and writes to electronic labels.

Description

1. Technical Field: [0001] The invention relates to a sensor management system, in particular to a vibrating wire sensor electronic label management system. 2. Background technology: [0002] In civil engineering, vibrating wire sensors are often used to measure various index parameters, including tension, pressure, stress, and displacement. The vibrating wire sensor is caused by the manufacturing process, and its product performance parameters are very discrete. Each sensor must be calibrated separately to obtain a set of basically unique performance parameters (the probability of repetition is extremely low). In use, each sensor and its corresponding measurement value must be distinguished, and then the characteristic parameters and measurement values ​​of each sensor are substituted into its calibration formula for calculation, in order to obtain the required physical quantity. If the measured sensor is not a model, the formula used is also different. [0003] At present, in p...
