Accompanying drawing explanation

Fig. 1 is the structured flowchart of double figures code pipe display system of the present utility model;

In accompanying drawing, the mark of each parts is as follows: 1, power module; 2, reset circuit module; 3, clock circuit module; 4, program module; 5, single-chip microcomputer; 6, charactron display module.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1, the utility model embodiment provides following technical scheme:

A kind of double figures code pipe display system of high voltage display device, comprise: power module 1, reset circuit module 2, clock circuit module 3, single-chip microcomputer 6, program module 4 and charactron display module 5, described power module 1, reset circuit module 2, clock circuit module 3, program module 4 is all connected with single-chip microcomputer 6 with charactron display module 5, described reset circuit module 2 comprises reset pin and reset circuit, comprise first order system power supply module, first order system peripheral power module, some second level system peripheral power module, control module supply module, power-supply management system, power-supply management system supply module and general supply.Between the input end of described first order system peripheral power module and general supply, be provided with controlled switch, this controlled switch and car-mounted electronic device main control unit supply module are electrically connected.

The input end of described first order system power supply module and general supply are electrically connected, and between the input end of the output terminal of first order system power supply module and car-mounted electronic device main control unit supply module and the input end of each second level system peripheral power module, are connected with respectively controlled switch; Controlled switch between the input end of the output terminal of first order system power supply module and each second level system peripheral power module is electrically connected with car-mounted electronic device main control unit supply module respectively.First order system power supply module is input end and the second level system peripheral power module of car-mounted electronic device main control unit supply module by the voltage transitions of general supply output.

Preferably, described charactron display module 5 comprises two positive-negative-positive triodes and two common anode utmost point charactrons.What triode play is switch and amplification level effect, and has the effect of sheet choosing, and what charactron play a part is to show, resistor be the effect of current limliting, prevent that dash current is excessive, burn out charactron.

The utility model has been realized demonstration and the switching to carrying out timing function by high voltage display device double figures code pipe, has reached diverse in function, flexible operation, the effect of failure rate is low.
