Drawings
FIG. 1 is a schematic view of an interface of a truck scale weighing instrument restored by a simulation terminal according to an embodiment of the present invention.
Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following figures and specific embodiments.
The design idea of the invention is that the interface of the weighing instrument of the truck scale is displayed on a remote computer, each button of the interface can be operated, and the displayed weighing data and information are completely consistent with those of a real instrument. For example, the instrument does not return to zero after the real object instrument displays the weighing of the automobile scale, and the zero clearing operation is required to be carried out on the real object instrument on site, so that a mouse can be lightly clicked on a computer opposite to a zero clearing button of the remote virtual simulation interface, and the zero clearing operation is finished, and the result is the same as the result of the operation on the real object instrument. If other operations are required for the physical instrument, such as: viewing the scale information, adjusting sensor parameters, setting meters, etc., may all be done here.
In order to realize the invention, the weighing instruments of the automobile scales need to be networked, and a virtual simulation system is installed in an office computer so as to realize the function of a virtual simulation terminal. The truck scale weighing instrument is reserved with an Ethernet interface, is connected with a concentrator by a network cable and is connected to a local area network by a switch; meanwhile, a remote computer (or a large host and a server) is used as a virtual simulation terminal and is also accessed into a local area network, and network IP data are respectively configured, so that the network connection can be completed. In addition, the truck scale weighing instrument can also be accessed to a local area network in a wireless access mode through the base station.
The software of the invention is based on Windows operating system, Access and SQL Server databases are adopted, and Microsoft NET frame is adopted as the programming and developing language. The software is divided into 2 parts, one part is used as instrument software to be installed in the truck scale weighing instrument, and the other part is used as terminal software to be installed in the simulation terminal.
And the instrument software acquires the patterns of the display interface in real time. The truck scale weighing instrument displays different interfaces each time, software can store a current picture to a memory of the instrument in real time, the instrument can be triggered to store the picture of the display interface in several ways, and firstly, the interface displayed by the instrument needs to be switched after receiving a command; secondly, the content displayed on the instrument interface changes, such as the weight change of the main interface, the information change of the code value, the temperature and the like in the sensor; thirdly, the instrument interface is unchanged, and theoretically, 3-5 pictures per second can be automatically stored in the instrument memory.
After the conditions are triggered, the instrument software stores the interface picture into the memory, mainly including two data, namely pixel position data similar to XY coordinates and color data of each pixel. The image then needs to be compressed to improve transmission efficiency, and the meter software first determines which regions in the image are the same and which are different. Images that include duplicate data (e.g., the background color blue of the meter) may be compressed, and only the start and end points of the blue need be recorded. However, the blue color may be masked by numbers, symbols, etc., which require additional recording, so that some duplicated data can be deleted, greatly reducing the size of the image to be saved.
The compressed data are transmitted to the simulation terminal by the instrument software through a network TCP/IP transmission mode after being compressed, the terminal software of the simulation terminal analyzes the compressed data and then restores the compressed data to a screen of the simulation terminal, the step of analyzing and restoring an interface image is opposite to the step of compressing pictures, and firstly, pixel point position data of each picture are obtained and are restored one by one in an XY coordinate mode; secondly, according to the color data, performing preliminary reduction from top to bottom by using XY coordinates, and performing according to the color requirement of each pixel.
After reduction, the picture is the reduced interface picture as shown in fig. 1, wherein the upper left corner in the picture is: an information display area; the lower left function keys are: an exit key; clearing the key; a unit conversion key; a summary key; a main menu key; the lower left corner function keys are: a cancel key; a clear key; peeling the key; a print key; the upper right functional keys are respectively: a numeric letter key; the lower right functional keys are: direction selection keys (four sides); enter key (middle). The terminal software takes the interface picture as 'Panel', and each key adds a 'Button' object as a virtual key. While the keys are in focus and trigger the action of pressing, the key is sent to the truck scale weighing instrument through a custom network protocol based on TCP/IP (such as a start command 02+ a button command abbreviation 'C' + an end command 0D and the like).
After the instrument software receives the command, according to different definitions of the command, different functions (adjustment setting of angular difference adjustment, addressing, correction and the like of sensor parameters; maintenance of self-diagnosis of the instrument of the automobile weighing system, sensor maintenance, log files and the like) are realized by combining the current display interface, the interface compression file is also fed back to the simulation terminal in real time, and the terminal software performs synchronous display to realize synchronous display of a unified function interface on any one side.
The remote virtual simulation system of the truck scale opens up a wide space for network application of the truck scale, breaks through the traditional 'island' truck scale application mode, enables managers and technicians to be in zero-distance contact with the truck scale, and can see the actual condition of the truck scale in real time and remotely control the truck scale no matter where you are. The system can be popularized to any container wharf, port and all industries as long as the system has computer network and truck scale application (even only one truck scale).
By implementing the invention, "energy conservation, consumption reduction, emission reduction and efficiency improvement" are really realized, and the invention contributes to the construction of intelligent and automatic intelligent ports.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
