Description
Technical field
The utility model relates to a kind of electronic price computing platform balance, especially relates to the digital pricing platform scale of the anti-cheating of a kind of centralized-control type.
Background technology
Existing electronic platform scale has independent load weighing unit and is connected column installation weighting display instrument.Principle of work: electronic platform scale is to utilize the small analog electrical signal of electronics strain gauge element stress and deformation principle output, sends weighting display instrument to by signal cable, carries out weighing operation and shows weighing result.Electronic platform scale has multiple display modes: charactron shows, liquid crystal display, and fluorescence display and liquid crystal dot matrix show.Weighting platform is installed overload protection arrangement, and the protection LOAD CELLS is to prevent extreme overload.The range of weighing of electronic platform scale is in 30-600 kilogram left and right.Different according to the model of weighting display instrument, the technical parameter of electronic platform scale and function are also different.Basic fundamental parameter: maximum capacity Max; Minimum weighing Min; Calibrating calibration n=Max/e; Scale division value e/d; Class of accuracy III; Rated voltage AC/DC; Product operative norm: GB/T 7722-2005 etc.Electronic platform scale belongs to the weighing apparatus of middle class of accuracy according to national standard.The function of electronic platform scale: the start automatic balancing, can remove the peel by hand/zero setting, the ac/dc Power supply, numeral shows weighing data, the accumulating function of can also gaining in weight, tally function, check weighing divides checking functions, the dynamic weighing function, data recording function is controlled warning function.Can match output interface: the RS-232 computer interfaceJi Suanjijiekou, printing interface can connect large screen display and make it the data justice openly.Electronic platform scale is weighed accurately, and degree of accuracy is high, and reaction velocity is fast, and is easy to use, and the weighing data intuitive display is eye-catching, avoided because the various errors that the collimation error of thinking causes.Rationally utilize weighing software can realize that the weighing data computer management realizes Scientific Measurement.
ExistingElectronic platform scale
Existing problems:
1. the cheating scale also claims " terrible scale ".Cheating mode has following several:
1. install the wireless remote control cheating device additional, arbitrarily add and subtract weight and recover and normally weigh.
2. repacking has the software of cheating function, with specifically operation, can arbitrarily add and subtract weight, the amount of money and quick restore funcitons.Due to the disguise of cheating, so the law-executor is difficult to find these " terrible scales ".
2. reequip, sell the ground lower chain that has of " terrible scale ".There is no shops, make house calls, the people who specializes in " terrible scale " is very careful and precise.
3. law-executor: some " terrible scales " shutdown start again are exactly standard scale, and the scene can't be caught." terrible scale " be careless variable body at any time, allows cost person all have a bad headache with the law enforcement office worker and finds once when their site inspection that some electronic scaless had problem, after being reacted to State General Administration for Quality Supervision, investigating through State Bureau and finds, problem goes out with it the software developer of some little factories.There is family more than 70 of electronic scales manufacturer in the whole nation at present, and some small enterprises just set up the engagement deviser from the outside in design chips due to small scale, wait chip design to get well the deviser and taken design charges just to separate.Some deviser stays some leaks intentionally when designing program, wait the dealer who just goes for this scale after leaving, and how the religion dealer gets some advantage from it scale furnishing cheating weighing apparatus.The somebody also specializes in such business, transfers one how much is received.
4. the vertification regulation of self-indicating scale " the JJG 539-1997 numeral " rules of fulfiling now are to work out in 1997, and cheating weighing apparatus is just to present in nearly 1 year, so nationally at present delimit without any laws and regulations.State Bureau was revising these rules originally, " after revision, request is produced producer and will be put on record to the software program of design; whether you the program of design have leak; passed examination issue licence again; if find later on the weighing apparatus that you sell and the program of registering with the proper authorities is inconsistent; will punish, like this can be from basically the weak point of cheating weighing apparatus being blocked.”
5. in each province's Large-scale terminal market management especially difficulty.Administration of Quality and Technology Supervision's law enforcement at present is more passive, publicity, and the standard test weight (citizen carry counterweight, first at the weigh counterweight, are used for contrasting the degree of accuracy of scale) of little weighing is provided in selective examination to citizen
At present the one-tenth that has of the scale of tracing to the source that uses of supermarket ornaments.
7. Large-scale terminal market such as Foochow fish market are three large wholesale markets, ground, the whole nation, and more than 3000 of electronic scales arranged, and floor area is carried out United Dispatching and supervision on 3 square kilometres, and unified management has all become the difficult point of managing.A lot of trade companies utilize weighing apparatus to carry out uncivil behavior, and the management of therefore weighing is unified to be identified and supvr's man-machine conversation, has become the difficult problem of this megastore.
Summary of the invention
For the problem that above prior art exists, the purpose of this utility model is to provide the digital pricing platform scale of the anti-cheating of a kind of centralized-control type.
The purpose of this utility model is to realize like this, the digital pricing platform scale of the anti-cheating of described centralized-control type, comprise load weighing unit, column and be arranged on weighting display instrument on column, the load weighing unit is provided with column, and its design feature is for also comprising wireless handheld terminal; Described weighting display instrument is provided with MCU, wired and wireless communication module, and wireless communication module comprises 3G network communication module and/or wifi network communication module and/or bluetooth module; Described MCU is connected with wired digital sensor of being connected with wireless communication module respectively; Described handheld terminal comprises operation keyboard, wireless communication module, teleswitch module and display module; Wireless communication module on wireless handheld terminal comprises 3G network communication module and/or wifi network communication module and/or bluetooth module.
