Abstract

The utility model discloses a scanning gun which includes a central processing unit, a power control module as well as an RFID (radio frequency identification device) module and a communication module. The RFID identification module is respectively connected with the power control module and the communication module. Compared with a commonly used code scanning gun in the prior art, the scanning gun integrates a code scanning module and a radio frequency identification module on one scanning gun; and a user can select code scanning or RFID scanning according to demands. When RFID scanning is used, not only the scanning distance is increased, but also the operation is simpler and more convenient, which can read the RFID labels of articles without barriers, and improves the satisfaction of users, thereby improving the product competitive strength.

Description

A kind of scanner

Technical field

The utility model relates to the scanning device in the logistics field, relates in particular to a kind of scanner.

Background technology

In the Item Management of logistics, usually have in a large amount of article storage and warehouse, await being assigned to various places, for the classification of article and effectively management be necessary, therefore usually article are numbered classification and adopt specific coding to discern and can improve the efficiency of management effectively.And the bar code scan rifle that adopts carries out the identification management of article at present, and the structure of bar code scan rifle is generally following a few part: light source, receiving trap, photoelectric conversion part, decoding scheme, computer interface.Their basic functional principle is: the light that is sent by light source passes through irradiation optical system above bar code symbol, the light of returning that is reflected passes through optical system imaging on photoelectric commutator, make it to produce electric signal, signal produces an aanalogvoltage after oversampling circuit amplifies, it with shine bar code symbol on the light of returning that is reflected be directly proportional, pass through filtering, shaping again, form the square-wave signal corresponding, be interpreted as the digital signal that computing machine can directly be accepted through code translator with simulating signal.Though the bar code scan rifle is simple to operate, has that recognition accuracy is low, decipherment distance is short, can not have the shortcoming that barrier is read, thereby be necessary to propose a kind of novel scanner and overcome these shortcomings.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of easy to operate, recognition distance, can not have the scanner that barrier is read.

For solving the problems of the technologies described above, the utility model adopts following solution:

A kind of scanner comprises central processing unit, energy supply control module, also comprises RFID identification module and communication module; This RFID identification module is connected respectively with communication module with described energy supply control module.

Wherein, also comprise the bar-code identification module, this bar-code identification module is connected respectively with communication module with described energy supply control module.

Wherein, also comprise the RFID identification switch, this RFID identification switch is connected with described RFID identification module.

Wherein, also comprise the bar-code identification switch, this bar-code identification switch is connected with described bar-code identification module.

Wherein, also comprise power switch, this power switch is connected with described energy supply control module.

Wherein, described communication module is a bluetooth module.

The utlity model has following beneficial effect:

With prior art bar code scan rifle contrast commonly used, the utility model has been integrated into bar code scan module and radio frequency identification module on the scanner, the user can select to adopt bar code scan or RFID scanning as required, not only increased scanning distance when using RFID scanning but also made that operation is easier, can carry out reading of article RFID label without barrier, improve user's satisfaction, and then improved competitiveness of product.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As everyone knows, RFID has following advantage:

(1) scanning identification aspect: RFID identification is more accurate, and the distance of identification is more flexible, and can accomplish penetrability and the reading of no barrier.

(2) the memory body capacity of data: the capacity of RFID maximum then has several MegaBytes, and along with the development of memory carrier, data capacity also has the trend of continuous expansion.

(3) contamination resistance and permanance: RFID has very strong repellence to materials such as water, oil and chemicalss; The RFID label is that data are existed in the chip, therefore can avoid stained.

(4) reusable: the RFID label then can repeatedly increase, revise, delete the data that store in the RFID label newly, makes things convenient for the renewal of information.

(5) volume miniaturization, shape variation: RFID are not limited by size and shape on reading, and have not been required to be the fixed measure and the press quality that read degree of accuracy and cooperate paper.In addition, the RFID label more can be toward miniaturization and the development of various form, to be applied to different product.

What (6) security: RFID carried is electronic type information, and its data content can make its content be difficult for being forged and altering via cryptoguard.

Based on above advantage, the utility model has increased the RFID scan function on the basis of existing bar code scan rifle, to realize accurately, to carry out fast, at a distance the identification of article tag.In the present embodiment, can use the utility model and come the article that electronic tag is installed are scanned, and this electronic tag support ISO18000-6C agreement, frequency is 860-960MHz.As shown in Figure 1, the multi-functional scanner that the utility model proposed comprises: central processing unit, energy supply control module, power switch, RFID scan module, RFID scanning switch, bar code scan module, bar code scan switch and communication module;

Wherein, energy supply control module provides power supply for RFID scan module, bar code scan module, communication module; The bar code scan module is used for carrying out the identification of the bar code of article when the bar code scan switch opens, and identifying information is sent to control terminal by communication module; The RFID scan module is used for carrying out the identification of the RFID label of article when the RFID scanning switch is opened, and identifying information is sent to control terminal by communication module; Communication module can use bluetooth communication module, adopts wireless transmission method, and scanner can be moved freely fully, is convenient to stock and the article that go out warehouse-in are discerned management.

Shown in Fig. 2 and 3, this figure is depicted as the external structure of multi-functional scanner in the present embodiment, comprising: RFID scanning switch and bar code scan switch (201), power switch (202), handle (203), RFID scan module (204), bar code scan module (205).

Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, only with reference to preferred embodiment the utility model is had been described in detail.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
