Method for reading wagon balance weighing displayer based on java

Abstract

The invention discloses a java-based reading method for a weighbridge weighing display, which includes a weighbridge, connecting the weighing display of the weighbridge, and connecting the weighing display of the weighbridge with a serial port or a USB interface of a computer. Based on the hardware structure, the reading method is realized The process is as follows: obtain the reading of the weighing scale transmitted by the serial port of the computer through the Java program, and write the reading into the web page or the application program. Compared with the prior art, a java-based reading method of the weighbridge weighing display of the present invention can directly read the readings of the weighing display of the weighbridge into other Java language-developed software, which greatly simplifies the original manual entry process and reduces errors possible, and at the same time realize the supervision of the weighing process, and the weighing personnel cannot tamper with the readings of the weighbridge, which is practical and easy to promote.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a java-based method for reading out a weighbridge weighing display. Background technique [0002] Usually, the reading program of the scale weighing display is developed using C language, C++ language, VB language, because C, C++, VB and other languages ​​can directly access the hardware interface of the computer, and the development is convenient, so most of the weighing display manufacturers use the above-mentioned development language Writing the reading program of the platform weighing display is a set of independent programs and does not provide an external access interface. This means that other programs cannot read its scale readings, use it, and cannot be integrated into projects developed in the Java language. Users can only manually record the readings of the weighbridge weighing display. Manual entry into other systems (such as purchase and sales software) is a cumb...

Problems solved by technology

This means that other programs cannot read its scale readings to take advantage of it and cannot be integrated into projects developed in the Java language

Users can only manually record the readings of the weighbridge weighing display. Manual entry into other systems (such as purchase and sales software) is a cumbersome process and human errors may occur. For the operation process that requires strict supervision, automatic supervision cannot be realized. Operation readings may be modified by staff and entered into the system

[0003] Java is currently the most widely used enterprise application development language. For programs developed in Java language, because they run in the Java virtual machine and are isolated from the operating system, they cannot directly access the computer hardware interface. Difficult, there is an urgent need to integrate the weighing readings of the platform scale display into the enterprise application developed by Java. At present, no domestic manufacturer provides a reading device for the weighing display of the platform using Java language development.
