Summarize it, by system and method for the present invention, can efficiently realize easily, to the unified management of electronic price computing equipment, stopping software cheating, and with low cost, be easy to extensive enforcement.
Embodiment
Below in conjunction with a preferred embodiment, technical scheme of the present invention is further described.
The present embodiment system relates to the anti-cheating total management system of a kind of electronic price computing scale, and it comprises:
Plural number electronic price computing scale, each electronic price computing scale comprises valuation sensing unit and main control unit, and is provided with one in described main control unit for generating and send the check code module of corresponding check code unique with this electronic price computing scale;
Store the identity information of this plural electronic price computing scale and the data center with the unique corresponding check code of each electronic price computing scale;
And, at least one hand-held checkout facility, its check code exported for receiving electronic price computing scale to be checked, and this check code is uploaded at least one data center, corresponding electronic price computing scale identity information is inquired about according to this check code by described data center, again Query Result is back to this at least one hand-held checkout facility, is then differentiated the legitimacy of this electronic price computing scale to be checked by reviewer according to this Query Result.
Aforementioned check code module preferably adopts the mode of solidifying in the main control unit of electronic price computing scale, changes it to prevent back street operators.
Particularly preferred, said curing mode by presetting a hardware identification code in main control unit, and calculates user by main control unit in conjunction with this hardware identification code and is burned onto corresponding program section in main control unit the later stage, and then produces corresponding check code.That is check code calculates generation when user needs to read, but be not actually stored in chip internal.
Or said curing mode also generates by the check code set up in the main control unit of each electronic price computing scale for exporting corresponding check code unique with this electronic price computing scale and output circuit and realizing.This output circuit with the discrete setting of all the other modules in main control unit, but can preferably adopt the form of integrated setting, to reach anti-cheating effect further.
The output of aforementioned check code realizes by the mode such as wireless or wired, but as one of comparatively preferred scheme, reaches this object, and make subsequent operation more simple by setting up a data output interface on electronic price computing scale with less cost.
As more specifically a kind of preferred implementation, this data output interface can use the Transistor-Transistor Logic level of RS232 to export or the RS232 level of standard exports, and the main control unit of aforementioned electronic balance can adopt mcu chip, this MCU chip has the crc16 check code function independently calculating and export this mcu user segment program code, illegal operation personnel so can be avoided to add algorithm in chip later stage of dispatching from the factory, then software programmers is stopped according to existing CRC16 check code, artificial fixing output one and the identical check code put on record.
As adopted previous designs, then for electronic price computing scale producer and user, its cost increase is very limited, also can not produce essence change to the structure of electronic price computing scale.
Preferably, the data transmit-receive module that described hand-held checkout facility comprises at least one data-interface, is connected with this at least one data-interface, and, the display module be connected with this data transmit-receive module.
Preferably, described data transmit-receive module comprises wireless communication module.
As more specifically a kind of preferred implementation, this hand-held checkout facility possesses data-interface, is used for receiving the check code of electronic price computing scale, possesses wireless transmission/reception module and display screen simultaneously, can show word and pictorial information etc.After hand-held checkout facility receives the check code of electronic price computing scale, this check code is sent to data center by wireless transmissioning mode, and receives the check information of data center's passback.
And for aforesaid data center, it can select data query server, possesses wireless or wireless and wired network savvy, the data message of all censorship electronic price computing scales of data center backup, and the CRC check code of hand-held checkout facility can be accepted, according to this check code query-related information, and Query Result is passed back to hand-held checkout facility.
Further, consider at electronic price computing scale, between hand-held checkout facility and data center, carry out when data are transmitted security, also by arranging encryption communication module respectively among electronic price computing scale, hand-held checkout facility and data center, such as, the mode of 128 (128bit) excusive wire and/or wireless communication module, make electronic price computing scale, between hand-held checkout facility and data center, adopt cipher mode to carry out data interaction, thus software cheating can be taken precautions against further.
Aforesaid wireless communication module can select known all kinds of wireless communication modules, such as, and 3G communication module, wifi communication module etc.
The verifying process flow of the present embodiment can be:
Electronic price computing scale producer electronic price computing scale is delivered to calibrating department calibrating in, by the identity information of this electronic price computing scale, comprise hardware element information, software version information etc. and CRC16 check code backup upload to data center.Data center records the hardware and software information of this electronic price computing scale in detail for later stage inquiry, testing person is when spot-check, read the CRC check code of electronic price computing scale, this check code is uploaded to data center to encrypt wireless communication mode, after data center receives this check code, by the electronic price computing scale identity information corresponding with this check code, (this information should comprise electronic price computing scale company-information, censored time, electronic price computing scale outward appearance, core electron components and parts etc.) pass back to hand-held checkout facility to encrypt wireless communication mode, testing staff is according to the information of passback, whether unanimously with the information of putting on record check this electronic price computing scale.As inconsistent, then can judge that this electronic price computing scale is as illegal electronic balance.
The present invention can efficiently realize, to the unified management of electronic price computing equipment, stopping software cheating easily, and with low cost, is easy to extensive enforcement.
Above preferred embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, done various conversion or modification, all belong to category of the present invention.
