Mine integral downhole portable electronic goods office terminal

Technical field

The utility model relates to a kind of mine integral downhole portable electronic goods office terminal.

Background technology

At present; Each bargh for the mine down-hole move the management of kinds of goods also extremely thin a little less than, management work mainly rely on manual work fill in the management feeding single, use the car list, handing over procedures such as down-hole kinds of goods are all singly confirmed through filling in simple feeding; This way to manage can only reflect the quantity of loading the kinds of goods railway carriage roughly; And can't reflect and join the specifying information of kinds of goods that the content of kinds of goods handing-over is too simple, causes sloppy management easily.Assist management owing to lack effective informationization technology means, make inventory information be difficult in time, add up exactly, inquire about and adjust, make the transportation dispatching of kinds of goods be difficult to carry out efficiently.In addition, carry out tracing and monitoring owing to lack effective technical means, the down-hole kinds of goods situation such as often occur sending wrong destination, falsely claim as one's own, lose easily in the process of transporting.

At present; Under ground environment, there have multiple kinds of goods office terminal to drop into to be on probation, yet all be that passive electronic label is discerned basically; Or just active electronic label is discerned; And do not have function of voice communication, do not have the information synchronization function, not to the automatic marshalling function of management objectives yet.Existing ground is with the kinds of goods office terminal and be not suitable for use under the mine enclosed environment, and special Safety Design is not passed through in existing kinds of goods office terminal when design simultaneously, can't directly apply under the coal mine usually.

The utility model content

The purpose of the utility model is to provide a kind of mine integral downhole portable electronic goods office terminal that can directly under mine, use, active and passive electronic label discerned and programmed, realize the electronic management of mine article at a distance.

For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of mine integral downhole portable electronic goods office terminal; Comprise central processor CPU, its signal input output end links to each other with the radio communication unit that is used to receive signal that active electronic label sends, the radio-frequency card reader that is used to read passive electronic label information, the WIFI module that is used for access of radio network respectively.

Can know by technique scheme; The utility model carries out communication through radio communication unit and active electronic label, simultaneously, carries out communication through radio-frequency card reader and passive electronic label; Can organize into groups, inquire about the down-hole railway carriage; Railway carriage institute cargo is carried out statistical query, solve under Minepit environment, because information interaction inconvenience causes problems such as moving target difficult management such as kinds of goods.In addition, the utility model also inserts wireless network through the WIFI module, make between down-hole and the surface work personnel that communication is more smooth and easy, information interaction more accurately and timely, manage, increase work efficiency, reduce the kinds of goods and the misuse of transport facilities with standard and refinement.
