In the embodiment shown in fig. 1, the electronic scale reading system of the present application includes: and the weighing unit 102 is used for weighing the objects to be weighed, wherein the weighing unit comprises a graphical interface module 1021, and the graphical interface module is used for developing a graphical interface and adapting to each interactive window in the interactive unit.
In the embodiment, the graphical interface module is adapted to each display window in the interactive unit, and serial port (COM) number selection, a start program button, a program running status bar, an electronic scale reading window, maximum minimization of the window, closing control and the like are realized. The graphical interface module utilizes JAVA JFrame to develop the graphical interface. Through the setting of the graphical interface module, each module in the interaction unit is windowed, so that the maximization, the minimization and the dragging control of each display window and the operation of hiding the display window in a taskbar can be realized, the tidiness of an electronic scale operation interface is realized, and the operation is convenient.
In the embodiment shown in fig. 1, in the electronic scale weighing system of the present application, the weighing unit 102 includes a serial port connection module 1022, which performs configuration of a serial port when weighing a weighing object, wherein, during weighing, a user presses a serial port selection button to select a serial port, and the serial port connection module performs configuration according to a selected target serial port and opens the target serial port to acquire weighing data of the weighing object.
In this embodiment, the serial port connection module mainly configures 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 programs and opens the corresponding target serial port, initialization action of the serial port is carried out, and the electronic scale starts to monitor and read weighing data of a weighed object.

Optionally, in the serial port connection module, an instantiation operation of the serial port operation class object is performed in advance, serial port parameters are created and assigned, wherein the serial port parameters include a serial port baud rate and a stop bit.
In this optional embodiment, when the serial port connection module performs normal operation, an instantiation operation of the serial port operation class object needs to be performed in advance. The instantiation operation of the serial port operation class object refers to that when the serial port is used, a corresponding serial port operation class (SerialPortUtils) needs to be declared before the serial port is used, and the instantiation value is just the declaration. And after the serial port is instantiated, correspondingly establishing serial port parameters and assigning values. The serial port parameters comprise a serial port baud rate and a stop bit. The serial port baud rate is a parameter for measuring the symbol transmission rate. Which indicates the number of symbols transmitted per second. Such as baud rate 9600 ═ 9600bps (bits/second); the stop bit is used to indicate the last bit of a single packet. Typical values are 1, 1.5 and 2 bits. Since the data is clocked over the transmission line and each device has its own clock, it is likely that a small asynchrony occurs between the two devices in the communication. The stop bit therefore not only represents the end of the transmission, but also provides the opportunity for the computer to correct the clock synchronization. And the smooth operation of the weighing process is ensured through the configuration of the serial port connection module and the assignment operation of the corresponding parameters.
Specifically, the serial port parameter further includes a checksum bit. Wherein, the data bit value is a parameter for measuring the actual data bit in communication. When a computer sends a packet, the actual data will not be 8 bits, with standard values of 5, 6, 7 and 8 bits. The specific arrangement of the data bits depends on the information to be transmitted by the electronic scale weighing system. In the technical scheme of the application, the data can be set to 8 bits.

In this embodiment, because electronic scales on the market are of various types, most of them are suitable for only a single specific data format, and therefore, when the weighing system is adjusted, different system environments and different data formats of the electronic scales need to be adapted, which complicates the process. Consequently, in order to make the electronic scale of this application all read weighing system be suitable for different electronic scales, this application sets up data format matching module, carries out the unity of format to the weighing data of different formats, makes this application can be applied to the electronic scale of different models on the one hand, and on the other hand, through the unity of data format, the convenience is to weighing data's reading, and the processing procedure is simpler.

In this alternative embodiment, since the unification of the data formats includes positive sequence processing of the weighing data, the weighing data can be output in positive sequence, conforming to the habit of reading by the user, without any additional processing.
Specifically, because serial data output formats of electronic scales of different brands are different, for example, if the serial data output format of brand a is 85.0000, 85.0000, 85.0000, and the serial data output format of brand B is 0.5800,0.5800,0.5800, it can be understood that the serial data output format of brand a is separated by a ═ number and the data is output in a reverse order, the serial data output format of brand B is output in a "" and a positive order, a separator of the data format template of brand a can be set to be "═ number", whether the data order is a positive order or not can be set, and the brand B is the same as the same. And then, data processing can be carried out according to the selected data format configuration when data are read, if the serial port data are of the brand A, the data are separated and analyzed by a mark after the serial port data are read, and if the data sequence is not, the data are processed in sequence, and the brand B is treated in the same way. Thus the data in the queue is always in the positive order of what is commonly seen. And then data output processing can be carried out.
Optionally, the weighing unit further comprises: and 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 with unified data format output by the Queue module, and transmits the weighing data to the interaction unit through the Queue according to a certain data length.
In this optional embodiment, the electronic scale reading system of the present application uses Queue for transmission of weighing data. When a Queue is used for data transmission, the length of the Queue is defined firstly when a program is instantiated. After declaring the serial port operation class, calling an init () initialization method of SerialPortUtils, reloading the method, and adding Queue parameters in the method so as to use the Queue during data processing. Reading data in real time during specific monitoring, judging if the length of the queue exceeds the specified length, according to the first-in first-out characteristic of the queue, firstly, using poll () to remove the data of the super-long part from the queue, and then adding add () into new data.

Therefore, in the electronic scale weighing system, the data accuracy module is arranged, the fluctuation of the weighing data in the weighing process is detected, and when the fluctuation range of the weighing data exceeds the preset threshold value, the data reading is abnormal, so that a user is prompted that the current weighing process is unstable, the reading is inaccurate, and the re-measurement is carried out; and when the fluctuation range of the weighing data is within the preset threshold value, the data is read normally, and the weighing data is output. Through the setting of the data accuracy module, the weighing accuracy is guaranteed.
Optionally, the weighing unit further comprises: and the serial port information reading module reads the weighing data acquired by the serial port connection module, converts the data stream of the weighing data into a character array and returns the character array to the interaction unit.
