Description

Integrated IPTV simulation testing device that can be portable

Technical field

The utility model provides a kind of integrated IPTV simulation testing device that can be portable, belongs to electronic technology field.

Background technology

The IPTV simulation testing device usually adopts is or can only carries out the demonstration of simple analog signal, can not carry out the demonstration of digital signal, if show that digital television signal also will add a set-top box, demonstration that perhaps can only digital signal can not be carried out the demonstration of analog signal, above-mentioned two kinds of displays all also will add power supply mostly in addition, can not use powered battery, be not easy to carry, its service behaviour needs further improvement.

The utility model content

The purpose of this utility model provides a kind of integrated IPTV simulation testing device that can be portable that can overcome above-mentioned defective, can adapt to analog signal and digital signal.Its technical scheme is:

Comprise IPTV set-top box and display, it is characterized in that: set up energy supply control module and battery, wherein the Voice ﹠ Video output port correspondence of IPTV set-top box is connected to the Voice ﹠ Video input port of display, the input termination extraneous signal of IPTV set-top box, the output port of energy supply control module links to each other with the power supply input port of IPTV set-top box, display respectively, and the input port of energy supply control module is connected to the AC power of battery and the AC power interface CON1 of battery port CON2 respectively.

Described integrated IPTV simulation testing device that can be portable, energy supply control module comprises AC power interface CON1, battery port CON2, power transfer module U1-3, optocoupler A1-2, triode Q, relay J, K switch, resistance R 1-3, LED and capacitor C, wherein AC power interface CON1 connects the input that 220v changes the input of 12v power transfer module U1 and meets optocoupler A1-2 through resistance R 1 respectively, an end and 12v that the output of power transfer module U1 is succeeded electrical equipment J contact respectively change 5v power transfer module U2 input, the output termination 5v of power transfer module U2 changes the input of 3.3v power transfer module U3, battery port CON2 succeeds the other end of electrical equipment J contact through K switch, the coil of relay J connects the collector electrode of triode Q1, the grounded emitter of triode Q1, its base stage connect the output of optocoupler A1-2 respectively through resistance R 2, through capacitor C ground connection, successively through resistance R 3 and LED ground connection.

Its operation principle is: import 220 alternating voltages by AC power interface CON1, the 220V alternating voltage becomes direct voltage by power transfer module U1, this direct voltage is battery charging voltage 12V, this output voltage provides power supply for display, the working power of coming the controller top box by mechanical switch or electronic switch K, if simple use display then disconnect this switch, when needing set-top box work this switch closure.When external 220V alternating current, can make two light lotus roots penetrate collection at the whole sine wave signal that exchanges point and be output as high level, this high level makes the triode conducting, can also give power devices when the relay conducting charges the battery power supply.

The utility model compared with prior art, advantage is on the basis of original display function, increased the IPTV set-top box, pass through energy supply control module, both organically are integrated into a portable integrated testing apparatus, both realized the function that can both show of digital signal and analog signal, can or there be the outdoor on-position of power supply at user's family yet, display image effect by display, evaluate and test the quality condition of IPTV input signal intuitively, the quick diagnosis paragraph that is out of order is the effective tool that the attendant of common carrier carries out the test of IPTV service maintenance.
