And the real-time understanding and grasp of the state of the electronic scale by the user are realized, the user experience is improved, the smooth proceeding of the weighing process is ensured, and the problems are timely processed.
In the embodiment shown in fig. 1, the electronic scale reading system of the present application includes: the weighing unit 102 is used for weighing objects, wherein the weighing unit comprises a graphical interface module 1021 and a graphical interface module, the graphical interface module is used for developing a graphical interface, and each interaction window in the interaction unit is adapted.
In this embodiment, the graphical interface module is adapted to each display window in the interaction unit, to implement serial port (COM) number selection, start program buttons, program running status bars, electronic scale reading windows, window maximum minimization, and closing control, etc. The graphical interface module develops a graphical interface by utilizing a JAVA JFrame. Through the arrangement of the graphical interface module, each module in the interaction unit is windowed, so that the operation of maximizing, minimizing, dragging and controlling each display window and hiding the display window in the task bar can be realized, the operation interface of the electronic scale is tidy, and the operation is convenient.
In the embodiment shown in fig. 1, in the electronic scale reading system of the present application, the weighing unit 102 includes a serial port connection module 1022, which performs serial port configuration when weighing a weighing object, where, during weighing, a user presses a serial port selection button to perform serial port selection, and the serial port connection module performs configuration according to a selected target serial port and opens the target serial port to perform acquisition of weighing data of the weighing object.
In this embodiment, the serial port connection module mainly performs the arrangement of the weighing data transmission serial port. After a user determines a target serial port in a plurality of serial ports, the serial port connection module is used for starting a corresponding target serial port, carrying out serial port initialization action, and starting monitoring and reading weighing data of the electronic scale on a weighing object.

In this alternative embodiment, when the serial connection module performs normal operation, an instantiation operation of the serial operation class object needs to be performed in advance. The instantiation operation of the serial operation class object refers to that when the serial operation class object is used for a serial port, a corresponding serial operation class (serial port Utils) needs to be declared before the serial operation class object is used, and the instantiation value is the declaration. After the serial port is instantiated, serial port parameters are correspondingly created and assigned. The serial port parameter comprises serial port baud rate and stop bit. The serial port baud rate is a parameter for measuring the symbol transmission rate. Which represents the number of symbols transmitted per second. Such as baud rate 9600=9600 bps (bits/second); the stop bit is used to represent the last bit of a single packet. Typical values are 1, 1.5 and 2 bits. Since the data is clocked on the transmission line and each device has its own clock, a small out-of-sync between the two devices in the communication is likely to occur.

In this embodiment, since electronic scales are of various types on the market, they are mostly suitable for only a single specific data format, and thus, when adjusting the weighing system, it is necessary to adapt the electronic scales to different system environments and different data formats, and the process is complicated. Therefore, in order to make the electronic scale of this application read all and call the system and be suitable for different electronic scales, this application sets up data format matching module, carries out the unification of format to the weighing data of different formats, on the one hand makes this application can be applied to the electronic scale of different models, on the other hand, through the unification of data format, makes things convenient for the reading of symmetry volume data, and processing procedure is simpler.

In this alternative embodiment, because unification of the data formats includes positive-sequence processing of the weighing data, the weighing data is enabled to be output in positive sequence, conforming to the habit of the user reading, without the need for further processing.
Specifically, because the serial data output formats of different brands of electronic scales have differences, if the serial output format of the brand a is = 85.0000 = 85.0000 =85.0000, and the output format of the brand B is 0.5800,0.5800,0.5800, it can be understood that the serial data output format of the brand a is separated by "=" and the data is output in reverse order, the serial data output format of the brand B is output in "and in positive order, and the data format template separator of the brand a can be set to" = ", whether the data sequence is in positive order, and the brand B is the same. And when the data is read, the data processing can be carried out according to the selected data format configuration, if the data is A brand, after the serial data is read, the data is separated and analyzed according to the configuration by the number of '=', and if the data sequence is not, the data sequence processing is carried out, and the brand B is the same. The data in the queue is thus always in the normal order. The data output process can be performed later.
Optionally, the weighing unit further comprises: the Queue module is used for defining the data length of the weighing data, is connected with the data format matching module, receives the weighing data which is output by the data format matching module and has uniform data format, and transmits the weighing data to the interaction unit through the Queue according to a certain data length.
In this alternative embodiment, the electronic scale reading system of the present application employs a Queue for the transmission of weighing data. When the Queue is used for data transmission, firstly, the length of the Queue is defined when a program is instantiated. The operation is finished in advance, after the serial port operation class is declared, an init () initialization method of the serial port Utils is called, the method is reloaded, and a Queue parameter is added in the method so as to use the Queue during data processing. And (3) reading data in real time in specific monitoring, judging that if the length of the specified queue is exceeded, firstly removing the data of the overlength part from the queue by poll () according to the first-in first-out characteristic of the queue, and then adding new data by add ().
