Description
Technical field
Electronic measuring instrument technical field of the present invention relates in particular to the technical field of data processing of electronic scale.
Background technology
Traditional weighing apparatus like platform scale, in process of exchange, only is as the instrument of metering, need not carry out the processing of data.Along with the extensive use of electronic technology, electronic scale begins to occur.The electronic scale that begins most also only be as metering outfit, add calculator function simultaneously, can in metering, carry out the calculating of dealing money.Again afterwards, along with the widespread usage of internet and computing machine, simultaneously; Along with closely during the last ten years, the generation of various food security accidents is like " melamine milk powder ", " clenbuterol hydrochloride " etc.; Make people pay close attention to greatly to food security, at this moment, as required; Retrospective food traceability system just occurred, it constitutes electronic scale and the internet with communication function and carries robot calculator (server) formation to the database of each link information of food, and electronic scale wherein is except metering and calculator function; Also have storage, print, identification and transfer function; Simultaneously, because the singularity of electronic scale, it is not only the fixedly place that is installed in the supermarket; Also be assemblied in the free market, the environment in free market is abominable, have in addition do not have local call and connect; What have does not have a network yet, simultaneously, because the needs of food security; Data transmission is very important in whole process of exchange, how to guarantee that the stable and accurate transmission of data then becomes a key;
Data transmission is the most reliable, and optimal mode is wire transmission, and the widespread use of current internet; All electronic scales in a market are constituted a LAN with Ethernet interface, get up through gateway and Internet connection again, through the mode of route; Can be long-range carry out data interaction with server; Its network topology is as shown in Figure 1, and it is the most reliable adopting wired mode to transmit data, the most stable; But the environment ground in current free market is very abominable, if adopt wired mode, then construction very bothers, and need transform all free markets simultaneously, and this need spend a large amount of funds.
And along with the use of wireless technology, current zigbee, wifi, the bluetooth etc. of being applied as the most widely can solve construction problem, in places such as free markets; Only need simple construction, increase radio network gateway, its network topology is as shown in Figure 2; Adopt wireless communication technology, can solve the problem of electronic scale in construction, but the most scabrous problem of wireless communication technology is: because the environment in free market is abominable; And complicated, near operating personnel even deliberately be placed on canister the antenna sometimes, and other reason; Make that radio communication data when carrying out data transmission are unstable; Even can leak the biography data, and data transmission is very important in whole bargain link, its stability requirement is for can not miss data.
Summary of the invention
The objective of the invention is data message, provide based on the electronic scale data transmission system of the REID method of unifying for the ease of the electronic scale in the stable collection market.
To achieve these goals; The invention provides a kind of technical scheme: based on the electronic scale data transmission system of REID; Comprise at least one electronic scale and server; It is characterized in that the electronic tag that also comprises repeater and be used to realize communicate by letter between electronic scale and the repeater;
Said electronic scale comprises central processing module, measures load module, display module, keyboard input module, power module, memory module and radio frequency identification module; Measurement load module, display module, keyboard input module, memory module and the radio frequency identification module of said electronic scale is connected with the central processing module of electronic scale respectively and is used for also receiving the control command from central processing module to central processing module transmission data, and the power module of said electronic scale is connected with radio frequency identification module and is used for to aforementioned modules power supply being provided with central processing module, measurement load module, display module, keyboard input module, memory module respectively;
Said repeater comprises central processing module, memory module, power module, communication module and radio frequency identification module; The memory module of above-mentioned repeater, communication module and radio frequency identification module are connected with the central processing module of repeater respectively and are used for also receiving the control command from central processing module to central processing module transmission data, and the power module of said repeater is connected with central processing module, memory module, communication module and radio frequency identification module respectively and is used for to aforementioned modules power supply being provided;
Said server is that the database that constitutes of the various data messages by electronic scale, repeater and the computer that carries these databases and communication module constitute, and it sets up direct data communication connection through the communication module of self and the communication module of repeater;
Can intercom mutually in twos between the communication module of said repeater and the communication module of server; The radio frequency identification module of said electronic scale and the radio frequency identification module of repeater can carry out exchanges data with electronic tag respectively.
To achieve these goals, the invention provides another kind of technical scheme: the electronic scale data transmission method based on REID comprises the steps:
Step 1: electronic tag is placed on the radio frequency induction district of electronic scale, and data transmission begins the back electronic scale and through self radio frequency identification module data message is written in the electronic tag;
Step 2: the radio frequency induction district that electronic tag is placed on repeater; Repeater reads the data message in the electronic tag through the radio frequency identification module of self; If reading in success then is cached to the data message that reads in the memory module of repeater, then withdraws from or read in once more if read in to get nowhere;
Step 3: repeater is removed the data message in the electronic tag through the radio frequency identification module of self after with the data message buffer memory;
Step 4: when communicating by letter of the communication module of the communication module of server and repeater is in idle condition, repeater will be buffered in data information transfer in the memory module in server.
The invention has the beneficial effects as follows: 1. construction is simple; Convenient, only need arrange that repeater gets final product in the place that electronic scales such as free market are concentrated, the quantity of repeater can be arranged according to the density of electronic scale; Repeater then is associated with server through various communication modes; Wired, or wireless, or internet etc. can adopt; 2. strengthen the stability of the transmission of data, because the characteristic of electronic scale itself, it does not allow in the transmission course of data, to lose data; Nor allow many data, if adopt electronic scale itself to add communication module, if adopt wired form; Construction is difficulty very; Expense is very big simultaneously, increases various costs, and this mode can increase stability of data transmission; If adopt wireless mode, then data transmission becomes very unstable, and obliterated data usually takes place; And adopt data transfer mode of the present invention, and then stability of data transmission is very high, can accomplish not lose data, and its reason is: the repeater most principal work is exactly to face the busy extent of controlling network; If idle, then transmit data, if unsuccessful transmission; Can be kept at and carry out buffer memory in its storage unit,, then wait for if busy; Data are carried out buffer memory simultaneously, as long as a free time, repeater just begins to transmit data.
