Abstract
The invention provides a method for verifying authenticity of a display value of an electronic balance. The electronic balance comprises a single-chip microcomputer and a display screen, and further comprises a communication port. The method specifically includes the steps of connecting both the display screen and the communication port to the IO port of the single-chip microcomputer, enabling the electronic balance to enter the weighing data state after the electronic balance is started up, continuing to receive data which need to be displayed when receiving a display command transmitted from the communication port, displaying the data on the display screen for a certain set time, determining whether the displayed data are tampered or not by observing the displayed data on the display screen, showing that the display portion inside the electronic balance is tampered if the data displayed on the display screen at the moment are not consistent with the data which need to be displayed in the display command, showing that the display portion inside the electronic balance is not tampered if the data displayed on the display screen at the moment are consistent with the data which need to be displayed in the display command, recovering the existing weighing display operation, and effectively verifying the authenticity of the display value of the electronic balance. By means of the method, the authenticity of the display value of the electronic balance can be effectively verified without increasing the hardware cost.
Description
Technical field
The present invention relates to electronic scales technical field, particularly relate to a kind of method verifying electronic scales displayed value authenticity.
Background technology
There is serious cheating in existing electronic scales, wherein a kind of relatively more outstanding fraudulent means revises displayed value exactly, such as unit price and weight or original value, the displayed value of total price diminish some and then give display display, this fraudulent means is more hidden, harm is very serious, because weight does not diminish, is difficult to perceive total price and is modified.Existing patent name: hand-held electronic balance anti-cheating supervisory detection method and system, application number: 201210404164.1, publication date is: the Chinese patent of 2013-02-13, this invention, by adjusting the main control unit of electronic price computing scale, can generate in hardware and export corresponding check code unique with electronic price computing scale, and when each electronic price computing scale licensing, by its identity information and check code unique corresponding with it in data center's internal memory deposit case, and the check code utilizing at least one hand-held checkout facility to receive electronic price computing scale to be checked to export in encryption communication mode, and it is uploaded to data center to encrypt wireless communication mode, intracardiac inquiry comparison respective electronic balance identity information in the data again, again Query Result is back to hand-held checkout facility to encrypt wireless communication mode, make reviewer can the legitimacy of real time discriminating electronic price computing scale to be checked thus.Namely this invention adopts main control unit to export a program ver-ify code, and handheld device communicates with remote server according to check code, and the identity information of inquiry respective electronic balance, turns back to handheld device.Whether the method can only be modified by detected electrons scale software, and cannot verify whether display is modified.In addition, existing patent name: anti-cheated electronic weighing scale, application number: 201120173307.3, publication date is: the Chinese patent of 2012-01-04, mention the way installing a rfid card in electronic scales inside additional to replace to prevent complete machine, but cannot verify whether display was modified.
Existing technology all cannot verify the authenticity that electronic scales shows, thus can not detect the cheating problem of the inner display circuit of electronic scales.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of method verifying electronic scales displayed value authenticity, effectively can verify the authenticity of electronic scales displayed value, and do not need to increase hardware cost, only need receive display command by original communication port, then the data received are shown, be simple and easy to implement.
The present invention is achieved in that a kind of method verifying electronic scales displayed value authenticity, and described electronic scales comprises single-chip microcomputer and display screen, and described electronic scales also comprises a communication port; Described method is specially:
Display screen is all connected with the I/O port of single-chip microcomputer with communication port,
Weighing data state is entered after electronic scales start, when receive that communication port sends display command time, continue to receive the data needing display, then a data display setting-up time on a display screen, determine whether display data were tampered by the display data of observing on display screen, if need the data that show inconsistent in the data that display screen now shows and display command, then illustrate that the inner display section of electronic scales was tampered; Unanimously, be not then tampered, recover original display operation of weighing, thus effectively verify the authenticity of electronic scales displayed value.
Further, described communication port is wire communication or wireless communication port, and wired connection port is serial communication, and wireless communication port comprises bluetooth, wifi or NFC.
Tool of the present invention has the following advantages: the present invention is by the communication interface of electronic scales, send command request electronic scales with external unit and show specific data, then check display screen whether to show the data of requirement display, thus effectively can verify the authenticity of electronic scales displayed value.
Accompanying drawing explanation
Fig. 1 is the structural representation of electronic scales of the present invention.
Embodiment
Refer to shown in Fig. 1, a kind of method verifying electronic scales displayed value authenticity of the present invention, described electronic scales comprises single-chip microcomputer and display screen, and described electronic scales also comprises a communication port; Described method is specially:
Display screen is all connected with the I/O port of single-chip microcomputer with communication port,
Enter weighing data state after electronic scales start, when receive that communication port sends display command time, continue to receive the data needing display, then a data display setting-up time on a display screen, this setting-up time, as 3 to 10 seconds, wherein, is preferably 3 seconds; Determine whether display data were tampered by the display data of observing on display screen, if need the data that shows inconsistent in the data that now show of display screen and display command, then display section, explanation electronic scales inside was tampered; Unanimously, be not then tampered, recover original display operation of weighing, thus effectively verify the authenticity of electronic scales displayed value.This display command is that external unit carries out sending, and passes to communication port by external unit, and this external unit can be handheld device or computing machine.
Wherein, described communication port is wire communication or wireless communication port, and wired connection port is serial communication, and wireless communication port comprises bluetooth, wifi or NFC.
In a word, the present invention, by the communication interface of electronic scales, sends command request electronic scales with external unit and shows specific data, then checks display screen whether to show the data of requirement display, thus effectively can verify the authenticity of electronic scales displayed value.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
