Background technology

At present traditional auction technique is quoted auction price for the auction teacher, and the buyer lifts board or the mode of raising one's hand is answered valency, not only the operating cost height, lose time, and conclusion of the business efficient is low.E-bidding system has appearred in rapid economy development, buyer adopts the e-bidding device that commodity are carried out " blank " and bids, excite the cut-throat competition between the buyer, so that the seller obtains the commodity maximum profit, this system replaces traditional auction teacher to be presided over and lifts the board mode of bidding, and eliminates human factor in the process of bidding, improve the auction efficient of bidding, reduced operation cost, strengthened enterprise competitiveness, stopped up enterprise procurement, sell leak.But the still imperfection of device of bidding that uses in the existing e-bidding system can not well satisfy the requirement of auction, occurs the mistake of bidding easily, has influenced normally carrying out of auction activity.

Summary of the invention

The purpose of this utility model is exactly for the device of bidding that solves in the present e-bidding system uses inconvenience, is prone to problems such as fault, provides a kind of and has simple in structurely, easy to use, and failure rate is low, the e-bidding device of advantages such as good stability.

For achieving the above object, the utility model adopts following technical scheme:

A kind of e-bidding device, it has housing, housing is provided with at least one key zone and LCD, also be provided with the IC-card interface module on the described housing, it is connected with central control module, and central control module also is connected with power module, online programming module, communication module respectively simultaneously, and central control module is controlled key zone by key scanning circuit, drive LCD by LCD MODULE, and utilize wireless and/or the wire communication module is connected with e-bidding system.

Described communication module is bluetooth module or other wireless transmitter module and e-bidding system communication.

Described communication module is the wire communication module, and it is by RS485 standard interface and e-bidding system communication.

Described key zone has two, is connected with central control module respectively.

Described power module adopts rechargeable battery, and its power consumption observation circuit is connected with central control module, and central control module scans key zone in setting-up time, as no signal then power module change the holding state of low-power consumption over to; Then enter normal power supply if any signal.

Described power module is the interface circuit that is connected with external power source.

Described key zone is mechanical type button or touch-key.

Also be provided with the work indicating device on the described housing, it is connected with central control module.

Described work indicating device comprises working station indicator, the success pilot lamp of bidding, identity validation pilot lamp.

E-bidding device of the present utility model can be divided into wire communication and two kinds of forms of wireless telecommunications according to the communication of itself and e-bidding system, has satisfied the different use habit of client; Simultaneously by its power supply mode, can be divided into and directly is connected with external power source or adopts two kinds of forms of rechargeable battery connection, satisfied the needs of the flexible use of client equally.By a plurality of key zones are set, can carry out a plurality of auction operations simultaneously, improved the efficient of auction, utilize IC-card that bidder's identity is confirmed, guaranteed the normal order of auction activity.In the electronics auction device that uses rechargeable battery, be provided with the power consumption observation circuit simultaneously, the duty of e-bidding device is monitored in real time, effectively reduce expending of electric power, prolonged the service time of equipment.

The utility model adopts the multitask design, and every utensil of bidding has independently A screen, the B screen keyboard of bidding, and can finish simultaneously 2 commodity price auctions; The e-bidding utensil has IC-card authentication function, passes through in bid people checking of demonstration behind the device plug-in card of bidding, and the device of bidding could use; Housing adopts the design of thickening ABS engineering plastics casing, avoids artificial destruction; The device of bidding breaks down, and communication line is isolated automatically.

The beneficial effects of the utility model are: simple in structure, easy to use, safe and reliable, and low-power consumption work.
