Abstract
The utility model relates to a price tag scale with a wireless communication function. The utility model comprises a host computer board (1) and a communication interface board (2), wherein the host computer board (1) comprises a CPU (101) which is used for controlling the opening of a cash box (7), an RS-232 chip (102) which is used for controlling a scan gun or a PC (9), and a communication chip (103); the communication interface board (2) comprises a I/F interface (202) which is connected with the cash box (7), and an RS-232C interface (201) which is connected with the scan gun or the PC (9); the communication interface board (2) also comprises a port (204) which is connected with a network bridge (3) and is used for wireless transmission; the network bridge (3) is connected with a wireless network card (4). The utility model has the advantages that the trouble of wiring can be omitted, the utility model can be moved anytime and anywhere, and the utility model can not be limited by net lines; additionally, if the encryption is used, the data transmission is safer.
Description
Technical field
The utility model relates to a kind of price-labelling scale, relates in particular to the communication module of this price-labelling scale.
Background technology
Price-labelling scale is a kind of electronic price computing scale, is mainly used in supermarket, the hypermarket; The article that client weighs needs are placed on the scale pan of this price-labelling scale, and this scale prints corresponding price tag.
As seen from Figure 1: price-labelling scale generally comprises the scale pan 101, base 102 and shows 103 3 parts; As seen from Figure 2: and the cavity of base is interior in order to realize that communication also comprises communication interface plate 2, motherboard 1 in the price-labelling scale that uses at present; This communication interface plate 2 comprises the Ethernet interface 203 that 201, one 202, one the I/F interfaces that link to each other with cashier's machine 7 of RS232C interface that are used for linking to each other with scanner or PC 9 have network savvy; Cash box 7 is inserted in I/F interface 202 places of communication interface plate 2 by first line 8, and the cpu chip 101 on the motherboard 1 says the word to cash box by second line 5 that links to each other with communication interface plate 2, realizes the unlatching of cash box 7; Scanner or PC 9 link to each other with the RS-232C interface 201 of communication interface plate 2 by the 3rd line 10, and the RS-232 chip 102 on the motherboard 1 carries out exchanges data (is for software upgrading or local transmission data if link to each other with PC) by second line 5 and scanner or PC 9; Communication interface plate 2 also provides an Ethernet interface 203 that confession is wired, and netting twine 11 can directly insert the Ethernet interface 203 on the communication interface plate, and the communication chip 103 on the motherboard 1 carries out wired exchanges data by 5 communications of second line.
Such price-labelling scale can satisfy some large-scale supermarkets, the desired electronic scales in sales field can be networked so that the requirement that unified management and data transmit.But also there is following defective: if networking is that netting twine directly is inserted on the scale, so just require around the placement scale, fixing netting twine socket to be installed, just have inconvenience if add scale or mobile scale later on again.
Summary of the invention
The utility model technical issues that need to address have provided a kind of price-labelling scale with wireless communication function, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: motherboard, communication interface plate; Described motherboard comprise the unlatching that is used to control cash box CPU, be used for RS-232 chip, the communication chip of gated sweep rifle or PC; Described communication interface plate comprises an I/F interface that links to each other with cashier's machine, a RS-232C interface that links to each other with scanner or PC; Described communication interface plate also comprises a port that link to each other with bridge, that be used for wireless transmission; Described bridge links to each other with wireless network card.
Compared with prior art, the beneficial effects of the utility model are: can save the trouble of wiring and can move whenever and wherever possible, can not be subjected to the restriction of netting twine; Encrypt if adopt in addition, can make data transmission safer.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 3: the utility model comprises: motherboard 1, communication interface plate 2; Described motherboard 1 comprises CPU101, the RS-232 chip 102 that is used for gated sweep rifle or PC 9, the communication chip 103 of the unlatching that is used to control cash box 7; Described communication interface plate 2 comprises an I/F interface that links to each other with cashier's machine 7 202, a RS-232C interface 201 that links to each other with scanner or PC 9; Described communication interface plate 2 also comprises 3 that link to each other with bridge, as to be used for a wireless transmission port 204; Described bridge 3 links to each other with wireless network card 4;
Described communication interface plate 2 can also comprise an Ethernet interface 203 that confession is wired, is used for wired networking data transmission.
The utility model just can be realized the communication of Wireless Networking having under Access Point (wireless network access point) environment.
Claims (2)
