Description
The utility model relates to a kind of registering instrument on duty, belongs to bar codes technique.
Bar codes technique is a kind of electronics that grows up in computer application practice and the new and high technology in information science technology field, become current main automatic identification technology, be widely used in industry automatic control and all kinds of management information system, and will be penetrated in many technical fields and the new high-tech product.
The bar code automatic recognition system is made up of scanner, code translator (being collectively referred to as reader), computing machine, printing device and display, system software, application software, has promptly formed a complete automatic recognition system by discrete multiple computer hardware and software.
(National Defense Industry Press publishes according to " bar code automatic identification technology ", Li Jinzhe etc. work, in Dec, 1991 first published, the 9th page) introduce, though barcode reading equipment is of a great variety at present, can be divided into two classes substantially: online reader and portable reader.Online reader is generally by ac power supply, and is connected the transmission data by cable between computing machine or the communication device.And portable reader is furnished with storer, and is battery-powered usually, is applicable to the occasion that off line is used; Dump main frame again after data aggregation carries out data processing by main frame.
The product P T-700 laser integral portable that excellent bar code company limited is won in Shenzhen machine of making an inventory has reflected our times bar codes technique level basically.PT-700 is portable data collection terminal, has 16 bit processors.640K internal memory, diagram LCD backlight, the keyboard and the laser scanner that are made of the letter and number symbol are combined as a whole, and DOS are provided operating environment.This laser machine of making an inventory is applicable to multinomial application such as package track, stock-taking, taking care of books, commodity retail.The intelligent data collection device of PT-815 that the said firm produces provides bar code input interface and super large memory capacity simultaneously, is suitable for using in open air and the rugged surroundings.The PT-870 portable multifunctional data collection device of the said firm can plug-in multiple choices be equipped with the formation one.Optional extension thermal printer, circumscribed memory body (1MB at most) and modulator-demodular unit etc. are to adapt to different demands.
But the data processing of the multiple data collection device that can see on above-mentioned and the market must have the support of system's machine, system software and application software.
In socialist construction, fire prevention, every safety precaution work such as antitheft are to be alert at all times, and at all can not adopt a casual attitude.The cost of countless heavinesses and profound lesson give people with deep education and many enlightenments.A wherein crucial aspect is exactly to pay attention to operator on duty's work, must strengthen management to work on duty.
The operator on duty is negligent of supervision, management, and the operator on duty is off one's guard, neglect one's duties, and causes unnecessary massive losses often for national wealth and life security; And the operator on duty is strengthened supervision and management, and the operator on duty scrupulously abides by the duty, and then may stop the generation of accident, even timely disposal perhaps takes place also can to find early, the loss that accident or disaster are caused is relieved to minimum level.
Because working particularity on duty even if the leader payes attention to, also is difficult to it is carried out effective supervision and management.
So, how could strengthen supervision and management conscientiously? this not only needs theoretically to strengthen education on the system and to manage, and more need be guaranteed on material conditions.
The purpose of this utility model is to provide a kind of registering instrument on duty at the problem of above-mentioned existence, utilize existing bar code identification technology, scanner, code translator, microprocessor, bar code card are carried out new composite design, widened the application of barcode technology, can exercise supervision, check all kinds of work on duty, the personnel on duty effectively, and then ensure the property and the life security of applying unit.
The purpose of this utility model is achieved in that
