Description

A kind of special-purpose recording pen

Technical field

The utility model relates to the special-purpose recording pen of a kind of number, refers more particularly to the special-purpose recording pen of a kind of ID of having number, password and real-time clock calendar.

Background technology

The digital recording pen just comes out in the eighties of last century the nineties, increase along with the FLASH memory span, and MP3 (media player) emerges in enormous quantities, the digital recording pen is widely known especially as the auxiliary function of MP3, it has the little advantage such as easy to carry of volume, and main application is minutes, the aspects such as record, investigation and evidence collection of listening to the teacher.Its basic function is energy live pick-up, broadcast, deletion, also can store on computers, can satisfy common applications, and is more loaded down with trivial details in the operation.In some special applications places, need easy and simple to handlely, can record Time of Day that sound takes place, sound pick-up outfit coding again truly, to the special-purpose recording pen that the recording document is maintained secrecy and can not be revised arbitrarily, at present domestic is blank out.Such as,, need be recorded in the scene when managing the public affairs law enfrocement official (public security organs, procuratorial organs and people's court, industry and commerce, the tax, municipal administration etc.), need the recording document can embody the real recording time on date, the sound pick-up outfit coding; No matter recording substance involves either party, this recording document all is complete true record full content, can not do any deletion or modification.

The utility model content

The technical problems to be solved in the utility model is: in order to satisfy above special applications place needs, provide the special-purpose recording pen of a kind of ID of having number, password and real-time clock calendar.The utility model is by in recording pen, and design one has real time clock circuit, and joins a unique ID number, one with this ID number access code one to one.In order to realize " foolproof " operation, this recording pen is designed to two key operations i.e. " recording " key and " a stopping " key.Each recording file also comprises ID number of recording pen except the voice data of specific coding compression, recording date and time.The broadcast of recording file and deletion, clock pin setting and modification have only by the special software on the PC (PC), after the input password passes through, could realize.This just provides effective guarantee to " people-oriented, enforces the law justly ".

In order to solve the problems of the technologies described above, the utility model proposes following technical scheme: it stops a kind of special-purpose recording pen operating key, a HOLD locking key, a LCD display, a USB interface by a main control MCU chip, a LCD chip for driving, NandFlash recording data-carrier store, a clock circuit, a Program flash program storage, an amplifying circuit, a recording operating key, and forms.This main control MCU chip is electrically connected at the LCD chip for driving, and this LCD chip for driving is electrically connected at LCD display.This main control MCU chip is electrically connected at NandFlash recording data-carrier store, clock circuit, Program flash program storage, amplifying circuit, recording operating key respectively, stops operating key, locking key, USB interface simultaneously.The button reserve battery of also being furnished with simultaneously a 3V in this clock circuit when recording pen is changed battery, uses reserve battery automatically, to guarantee the present clock accuracy.

Embodiment

See also Fig. 1 to Fig. 5, it stops a kind of special-purpose recording pen operating key 8, a HOLD locking key 9, a LCD display 10, a usb 11 by a main control MCU chip 1, a LCD chip for driving 2, NandFlash recording data-carrier store 3, a clock circuit 4, a Program flash program storage 5, an amplifying circuit 6, a recording operating key 7, and forms.This main control MCU chip 1 is electrically connected at LCD chip for driving 2, and this LCD chip for driving 2 is electrically connected at LCD display 10.This main control MCU chip 1 is electrically connected at NandFlash recording data-carrier store 3, clock circuit 4, Programflash program storage 5, amplifying circuit 6, recording operating key 7 respectively, stops operating key 8, locking key 9, usb 11 simultaneously.The button reserve battery 12 of also being furnished with simultaneously a 3V in this clock circuit 4 when recording pen is changed battery, uses this reserve battery 12 automatically, to guarantee the present clock accuracy.

The concrete structure of the special-purpose recording pen of the utility model is as follows: this LCD display 10 is arranged on the front of main body, this stops the left side that operating key 8 is arranged on main body, this recording operating key 7 and HOLD locking key 9 are arranged on the right side of main body, and this usb 11 is arranged on the bottom of main body.This main control MCU chip 1, LCD chip for driving 2, NandFlash recording data-carrier store 3, clock circuit 4, Program flash program storage 5, amplifying circuit 6 are arranged on the inside of main body.

Its principle of work is as follows: the storage address that at first defines an ID sign indicating number and access code when program design to recording pen, this storage address can be arranged among the Flash of main control MCU chip 1 inside, also can be arranged in its outside Program flash program storage 5, can also be arranged in the boot section of Nandflash recording data-carrier store 3.Press recording operating key 7, this main control MCU chip 1 is after accepting record command, earlier from clock circuit 4, read current date and time, set up the recording file archives with current date and time, and the ID sign indicating number of this recording pen is placed on the file header (or agreement somewhere) of recording file.The main control MCU chip 1 of this recording pen connects operating key commonly used three: the operating key 7 of promptly recording, stop operating key 8 and HOLD locking key 9.And the HOLD locking key 9 that this main control MCU chip 1 connects is that locking key opening this recording pen of following time could be recorded at this key only, and still the file of being recorded can not be play, and can not delete.Behind the End of Tape, this recording pen is connected with the PC computing machine by the usb 11 that is connected in main control MCU chip 1, recording pen is with after the PC computing machine is connected, main control MCU chip 1 is at first accepted the access code that transmits from PC computing machine special software, if this password is identical with the password of recording pen main control MCU chip 1 stored, it is open with the form of general USB flash disk then will to record.Otherwise, the visit of this main control MCU chip 1 refusal PC computing machine.Have only password to pass through could pass through of broadcast backup and the deletion of PC computer realization after this main control MCU chip 1 authentication to the recording file in this recording pen, and operations such as clock pin setting and modification.The button reserve battery 12 of also being furnished with 3V in addition in this real time clock circuit when recording pen is changed battery, uses this reserve battery 12 automatically, to guarantee the present clock accuracy.
