Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is described in detail below in conjunction with accompanying drawing.
A kind of product inquiry system based on WLAN (wireless local area network), comprise portable terminal 15 by the camera collection bar code image, extract the image processing server 11 of bar code information from bar code image, store the product price server 10 of bar code information and product price corresponding relation, be used to the Wireless Local Area Network Gateway equipment 14 of the information of transmitting; Portable terminal 15 is provided with the WLAN (wireless local area network) chip, product price server 10 is connected with image processing server 11, image processing server 11 is connected with Wireless Local Area Network Gateway equipment 14, and Wireless Local Area Network Gateway equipment 14 is connected with portable terminal 15 by WLAN (wireless local area network).
Image processing server 11 is used for extracting bar code information from bar code image, and extracting bar code information from bar code image is prior art, is not giving unnecessary details its principle here.Above-mentioned portable terminal 15 can be mobile phone, PDA etc.; Commercially available portable terminal 15 has camera mostly, and the pixel of camera is more and more higher, meets the requirement of gathering bar code image; After portable terminal 15 collects bar code image, send to the Wireless Local Area Network Gateway equipment 14 of appointment by WLAN (wireless local area network); Concrete, each production marketing merchant can be provided with a product searching platform, and the product searching platform is related with Wireless Local Area Network Gateway equipment 14, and portable terminal 15 sends to bar code image the production marketing merchant's of this product product searching platform.Product price server 10 stores bar code information and product price corresponding relation, every kind of corresponding bar code of product, and the product price of every kind of product correspondence can be input to product price server 10 in advance by the production marketing merchant.
Portable terminal 15 is by the camera collection bar code image, send to Wireless Local Area Network Gateway equipment 14 by WLAN (wireless local area network) then, Wireless Local Area Network Gateway equipment 14 sends to bar code image image processing server 11 again, image processing server 11 extracts bar code information from bar code image, and obtain the product price of this bar code information correspondence from product price server 10, feed back to portable terminal 15 by WLAN (wireless local area network) then.For the indefinite product of price that short-term is put on display or sales promotion regularly or other situation cause, production marketing merchant or administrative authority can arrange WLAN (wireless local area network), the purchase personnel use portable terminal 15 can know product price, the utility model is easy to use, can improve trading efficiency, reduce transaction cost.The technical program can be applicable to the megastore, also can be applicable to places such as commodity fair; Purchase personnel, sales force, supervisor etc. all can use portable terminal 15 inquiry product prices.
