Description

Commodity operating period tracking scope after sale

Technical field

The utility model relates to the electronic product field, particularly program control, the liquid crystal display electron timing demonstration correlation technique of microelectronics.

Background technology

Prior art is to the follow-up service of commodity after sale, the main means such as papery invoice outward and guarantee card that rely on realize, this mode promptly can not truly reflect the time of selling owing to human factor, as the time of making the product of factory, dealer's selling time is because interest relations, invoice for sales date and actual sell not corresponding etc. often occur, bring many uncertain factors for enterprise's after sale service.

Technology contents

The utility model purpose is the deficiency of following the tracks of at existing after sale service, provide a kind of simple in structure, cost is low, once entering trace routine, manually can't intervene, but the accurate recording display of commodity tracking scope of service time after sale.

A kind of operating period tracking scope of commodity after sale, the described track display of following is made up of the circuit part and the housing that circuit part can be placed in one.Being made up of single-chip microcomputer and peripheral components of circuit part, be integrated with following assembly in the single-chip microcomputer: central authorities handle CPU, storer ROM, RAM, LCD driver, oscillator OSC, power controller and I/O port.The pin COM and the SEG of the LCD driver in the single-chip microcomputer connect LCDs, the pin OSCI of oscillator OSC and OSCO pass through capacity earth respectively after connecing quartz crystal oscillator, the pin VDD of power controller is arranged in the positive pole of battery in the housing, pin GND connects battery cathode, two control ends of tracking scope, one termination single-chip microcomputer input end P0, the other end are connected in positive source, power cathode, the output port optional one and join.

In the commodity operating period tracking scope, described housing is divided into face-piece and drain pan after sale, and LCDs places on the face-piece, and the pin COM and the SEG of the LCD driver of circuit part electrically connect mutually by conductive adhesive tape and LCDs.

In the commodity operating period tracking scope, described housing is the transparent material housing after sale, and housing drain pan and face-piece are provided with literal diagram release.Drain pan and face-piece assembling back are non-dismountable.

That advantage of the present utility model is is simple in structure, cost is low, accurate service time of immutable automatic record display of commodity, the technological means of providing convenience for after sale services such as commodity tracking, guarantees.

A operating period tracking scope of commodity after sale is made up of housing (1), circuit unit (2), LCDs (3).LCDs (3) is loaded in the window (13) of face-piece (11), and it was realized with connecting by conductive adhesive tape (31) of circuit unit (2).Circuit unit (2) selects for use 6614 types, I/O lead that control end connects (28) and lead (29), battery folder (23), button cell (22) and electronic component to form by circuit board (20), single-chip microcomputer (21).Circuit board (20) is fixed on the face-piece (11) by screw (4); After single-chip microcomputer (21) pin OSCI, OSCO connect quartz crystal F two ends respectively, by capacitor C 1, C2 ground connection; Pin VDD connects positive source; Pin RESET connects positive source by resistance R 1; Pin S0～S5, C0～C3 connect LCDs (3) by conductive adhesive tape (31); Pin GND connects power cathode; Battery folder (23) is welded in the jack (25) of circuit board (20), and button cell (22) inserts in the folder crack of battery folder (23) and circuit board (20); Pin P0 connects lead (28) by resistance R 2 and draws outside the shell; Power cathode connects lead (29) and draws outside the shell.

The program circuit that solidifies in the single-chip microcomputer (21) as shown in Figure 8, is limited by lead (28) and lead (29) and connects and the process that disconnects:

A. the two leads connection time just disconnects above a certain setting-up time, and programmed decision the utility model is not loaded onto commodity.

B. two lead connection times did not disconnect above a certain setting-up time, and programmed decision the utility model has been loaded onto commodity.After this in a single day disconnect, the programmed decision commodity are sold, and displaying contents will be as time passes, increases 1 every day, and is irreversible.Three half word maximums show 1999 days.(Figure 10)

Because commodity are when dispatching from the factory, the utility model is fastened two leads on commodity securely, and commodity must be untied two leads and could use, thereby has guaranteed that commodity sell the accurate counting of service time afterwards.

For commodity that the utility model is followed the tracks of are corresponding one by one, the utility model housing (1) is made the transparent body, place the papery promotional literature that is printed on this commodity code information in the housing (1), reach that commercial product identification is confirmed and the purpose of demonstration effect.
