In general embodiments, each display screen unified management, each display screen is correspondingly provided with ID address and (compiled addressCode), the ID address (geocoding) can be determined by addressing system.It also stored in server memory 3 correspondinglyThe address signal of display screen ID address；Server is by address signal wirelessly with display regular instructions table or/and characterData are sent.
Fig. 8 is refer to, when electronic label display system works, first, the input module 7 of server can carry out no line numberIt is believed that the editor of number 2 (such as display regular instructions, character datas), when edits are complete, no line number is carried out by transmitting wirelessly end 9It is believed that numbers 2 transmission；Then, it can receive and be sent from server in this end of image data processing unit, wireless receiving module 1Wireless data signal 2, the wireless data signal 2 will be transmitted in processor 4 and handled, processor 4 call display ruleThen character data is generated dot matrix image data by the display regular instructions in instruction catalogue, and the dot matrix image data of generation is passed throughWired sending module 5 is sent to dot matrix display screen 6.Dot matrix display screen 6 is after image data is received, so that it may completes to show workMake.
Fig. 4 is refer to, another further aspect of the embodiment of the present invention provides a kind of electronic tag display methods, and it includes following stepSuddenly：
s201：Server sends wireless data signal 2, and the wireless data signal 2 is display regular instructions table and number of charactersAccording to；
s202：Image data processing unit receiving radio data signal 2, and call the display rule in display regular instructions tableThen character data is generated dot matrix image data by instruction, is sent to dot matrix display screen 6 by the dot matrix image data of generation is wired；
s203：Dot matrix display screen 6 shows dot matrix image data.
In general embodiments, with the dot matrix display screen 6 of image data processing unit wired connection for two or two withOn, such as the electronic shelf tag in supermarket, newly-generated dot matrix image data can carry out wired transmission by way of bus,Bus may include data/address bus, address bus and controlling bus, be respectively intended to transmit data, data address and control signal.
In other embodiments, dot matrix display screen 6 can also be one, realize that data pass again by the mode of busIt is defeated, complete the display of dot matrix display screen 6.
During bus marco, each dot matrix display screen 6 is correspondingly provided with an ID address (geocoding), the identityAddress (geocoding) can realize addressing and control by way of bus.Show for example, wireless receiving also includes corresponding dot matrixThe address signal (geocoding) of display screen 6, determine to need by the address signal (geocoding) using bus (address bus)Position of the dot matrix display screen 6 of display in image data processing unit, i.e., register position corresponding to dot matrix display screen 6.After determining address signal, dot matrix image data is sent to corresponding dot matrix display screen 6 and shown by bus (data/address bus), i.e.,Bus (data/address bus) completes the image data by being sent to register corresponding to corresponding dot matrix display screen 6, by processor 4Display action.
In a preferred embodiment, wireless data signal 2 can also include basic image data, and the basic image data includesGraph data, the graph data can be the design elements such as picture, mark.When image data processing unit receives basic picture numberAccording to when, store the basic image data in memory 3.Processor 4 is by calling the character for showing that regular instructions will receiveData are combined generation dot matrix image data with basic image data, and the display regular instructions can be invalid data signal 2 or depositDisplay regular instructions in reservoir 3.
In general embodiments, memory 3 can be stored with one or more display regular instructions, when wireless receiving module 1During receiving radio data signal 2, processor 4 detects to wireless data signal 2, when in wireless data signal 2 only have character dataWhen, processor 4 determines the position of corresponding dot matrix display screen 6 that character data shows by the address signal in wireless data signal 2Put, processor 4 updates the character data newly received into the register of corresponding dot matrix display screen 6, then calls memory 3In original storage display regular instructions, the character data after being updated in the register is generated into image data, and by the pictureData output is to dot matrix display screen 6；When only including display in the wireless data signal 2 that wireless receiving module 1 detects receptionDuring regular instructions, processor 4 understands the display regular instructions stored in preferentially more new memory 3, the display rule that will newly receiveInstruction replaces original display regular instructions and is stored in memory 3, then calls the display after renewal to advise by processor 4Then original character data being stored in memory 3 is generated new image data by instruction, is shown；Work as wireless data signal2 when including character data and display regular instructions, the display regular instructions that processor 4 can be stored preferentially in more new memory 3And character data, the display regular instructions that will newly receive replace original display regular instructions and are stored in memory 3,Processor 4 determines the position of corresponding dot matrix display screen 6 that character data shows by the address signal in wireless data signal 2,The character data newly received is updated into the register of corresponding dot matrix display screen 6, then called by processor 4 by processor 4Original character data being stored in memory 3 is generated new image data by the display regular instructions after renewal, is shown.
In further embodiments, received simultaneously when wireless receiving module 1 receives character data to should character dataShow regular instructions, i.e., wireless receiving module 1 detect in the wireless data signal 2 received and meanwhile include character data withRegular instructions are shown, and the display regular instructions can be preferential just for specific one or multiple dot matrix display screens, processor 4Show the renewal of regular instructions, be followed by subsequent processing the display regular instructions that device 4 calls the wireless receiving module 1 after renewal to receiveThe character data that the wireless receiving module 1 is received generates dot matrix image data, and the dot matrix image data is exported to specificDot matrix display screen 6.
