Description

A kind of charactron detecting system

Technical field

A kind of charactron detecting system of this utility model design.

Background technology

Charactron is a kind of display screen, can input relative electric current by the pin different to it and make it Bright, luminous thus demonstrate numeral.Due to its low price, use simple, electrical equipment is applied the widest General.In order to increase the ex factory pass rate of electrical equipment, it is necessary to logarithmic code pipe detects, it is ensured that its quality.

Utility model content

This utility model provides a kind of easy charactron detecting system, can not only find out charactron intuitively Quality, and be capable of detecting when that febrile state when charactron works is the most normal.

In order to achieve the above object, this utility model include single-chip microcomputer, power module, charactron module to be measured, Resistance, Voltage stabilizing module and power lamp, described power module is connected with power lamp, described electricity Source module is that single-chip microcomputer is powered by Voltage stabilizing module, and described charactron to be measured is 1,2,4 or 6 Digital sum pipe, eight pins of the p0 mouth of the I/O mouth of described single-chip microcomputer by resistance respectively with number to be measured Segment signal interface a, b, c, d, e, f, g, dp of tube module connects, described charactron module to be measured Each common port com mouth is connected with single-chip microcomputer P2 mouth pin respectively.

Further comprising temperature sensor and buzzer module, described temperature sensor will gather to be measured The temperature of charactron module passes to single-chip microcomputer, and described single-chip microcomputer is connected with buzzer module.

This utility model simple in construction, it is achieved convenient, testing result is directly perceived, it is possible to detection multidigit nixie tube Quality, the heat condition during work of detection charactron is the most normal simultaneously, and is provided with mu balanced circuit, it is ensured that single Sheet machine is powered stable.

Accompanying drawing explanation

Fig. 1 is the structured flowchart of a kind of charactron detecting system described in the utility model.

Reference in figure is respectively as follows: 1. single-chip microcomputers；Charactron module the most to be measured；3. power module；4. voltage stabilizing mould Block；5. power lamp；6. temperature sensor；7. buzzer module.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in detail.

As it is shown in figure 1, this utility model include single-chip microcomputer 1, power module 3, charactron module 2 to be measured, Resistance, Voltage stabilizing module 4 and power lamp 5, described power module 3 is connected with power lamp 5, institute The power module 3 stated is powered for single-chip microcomputer 1 by Voltage stabilizing module 4, and described charactron module to be measured 2 is 1 Position, 2,4 or 6 Digital sum pipes, eight pins of the p0 mouth of the I/O mouth of described single-chip microcomputer 1 pass through Resistance is connected with segment signal interface a, b, c, d, e, f, g, dp of charactron module 2 to be measured respectively, institute Each common port com mouth of the charactron module 2 to be measured stated is connected with the P2 mouth pin of single-chip microcomputer 1 respectively. Single-chip microcomputer drives the charactron in charactron module 2 to be measured by dynamic scan principle, makes numeral method set Fixed numerical value, observes charactron and the most normally works.Charactron module 2 to be measured is by one or more numbers Pipe forms, and charactron has eight pins of a, b, c, d, e, f, g and dp, and each charactron draws accordingly Foot is connected, and the most each charactron correspondence section is connected in parallel, and one has eight ports, these 8 ports Doing segment signal interface, the common port of each charactron of charactron module to be measured is called position and selects interface, each Position selects interface and a p2. interface to connect.Power module 3 is powered for single-chip microcomputer 1 simultaneously, Voltage stabilizing module 4 To burning voltage, the effect of protection single-chip microcomputer 1, the power lamp 5 at mains side is used for indicating the power supply be In no normal work, single-chip microcomputer 1, by controlling driven by program charactron, utilizes dynamic scan principle to make to own A, b, c, d, e, f, g, dp of charactron light successively, low by the resolution frequency of human eye, make to seem The brightest, thus judge that charactron is the most normal.

Further comprising temperature sensor 6 and buzzer module 7, described temperature sensor 6 will gather certainly The temperature of charactron module 2 to be measured passes to single-chip microcomputer 1, and described single-chip microcomputer 1 is connected with buzzer module 7. In order to ensure the quality of charactron, the febrile state in charactron work process is also to affect its quality and life-span A factor, when Single-chip Controlling charactron works, suitably increase the working time of charactron, pass through The temperature data of the charactron that temperature sensor 6 can gather, judges that charactron is the most normal.Charactron After the temperature data of detection is passed to single-chip microcomputer, single-chip microcomputer is had to carry out data processing judgement, when work temperature When degree is more than a certain value, single-chip microcomputer 1 can control coupled buzzer module 7 and sound the alarm, from And illustrate that the quality of this charactron does not gets to requirement, complete the detection of logarithmic code pipe.

Above in conjunction with accompanying drawing, this utility model made exemplary description, it is clear that this utility model specific implementation Do not limited by aforesaid way, as long as have employed the various unsubstantialities that technical solutions of the utility model carry out Improve, all in the protection domain of this utility model report.
