[description of drawings]
Fig. 1 is the circuit theory diagrams of the specific embodiment of the present invention.
[embodiment]
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, be one embodiment of the present invention.
A kind of device that upgrades content of television internal USB storing equipment of the present invention, described televisor 10 comprises an external USB interface J1, and the player 12 and the internal USB storing equipment 14 that are connected respectively by data line with this external USB interface J1, described external USB interface J1 connects the USB interface 22 of a computing machine 20.Power end VCC, a phase inverter U1B of the described external USB interface of connecting successively between the power end PC-VCC of the USB interface 22 of described computing machine 20 and the power end USB-VCC of described USB memory device 14, an and switching tube Q2, the power end VCC of described external USB interface is connected with the positive terminal of described phase inverter U1B, and described switching tube Q2 is connected with the negative phase end of described phase inverter U1B.A phase inverter U1A, an and switching tube Q1 successively connect between the power end MAIN-VCC of described player 12 and the power end USB-VCC of described USB memory device 14, the power end MAIN-VCC of described player is connected with the positive terminal of described phase inverter U1A, and described switching tube Q1 is connected with the end of oppisite phase of described phase inverter U1A.Described switching tube Q1 is the P channel MOS tube, and described switching tube Q2 is the P channel MOS tube.
The data line pin D+ of the USB interface 22 of described computing machine 20, D-by the external USB interface J1 of televisor directly and the data line pin D+ of player 12 and internal USB storing equipment 14, D-connects, the power end PC-VCC of the USB interface 22 of described computing machine 20 is by the power end VCC of televisor USB interface J1, phase inverter U1B, switching tube Q2 and inductance FB2 are connected with the power end USB-VCC of described USB memory device 14, and the power end MAIN-VCC of described player 12 is by phase inverter U1A, switching tube Q1 and inductance FB1 are connected with the power end USB-VCC of described USB memory device 14.The power end MAIN-VCC of wherein said player connects the positive terminal 3 of described phase inverter U1A, and the negative phase end 2 of described phase inverter U1A is connected with described switching tube Q1.The power end MAIN-VCC of described computing machine connects the positive terminal 5 of described phase inverter U1B, and the negative phase end 4 of described phase inverter U1B is connected with described switching tube Q2.Wherein said inductance FB1 and described inductance FB2 play the circuit protection and filter clutter in circuit.
Its concrete principle of work is as follows: when the content in described televisor 10 its built-in USB memory devices 14 of broadcast, computing machine 20 is not connected with televisor 10, thereby the power supply PC-VCC of computing machine 20 is 0V, and the power supply MAIN-VCC of player 12 is 5V.After phase inverter U1A was anti-phase, the grid of described P channel MOS tube Q1 was a low level, P channel MOS tube Q1 conducting, thus make the power end USB-VCC conducting of the power end MAIN-VCC and the described USB memory device 14 of described player 12.Data line pin D+, the D-of the USB interface 22 of this computer-chronograph 20 become high-impedance state, and player 12 can normally read the content of described USB memory device 14.Wherein said inductance FB1 and described inductance FB2 play the circuit protection and filter clutter in circuit.
When computing machine 20 upgrades the content of described USB memory device 14 by described televisor 10 external USB interface J1, earlier described televisor 10 is turned off, at this moment, the power supply MAIN-VCC of described player 12 is 0V, switching tube Q1 ends, thereby the power supply USB-VCC of described USB memory device 14 no longer is subjected to the influence of the power supply MAIN-VCC of televisor 10, and simultaneously, data line pin D+, the D-of player end become high-impedance state.Directly computing machine 20 and televisor 10 external USB interface J1 are connected, at this moment, the power supply PC-VCC of computing machine 20 is 5V, after phase inverter U1B was anti-phase, the grid of P channel MOS tube Q2 was a low level, P channel MOS tube Q2 conducting, thereby make the power end USB-VCC conducting of the power end PC-VCC and the described USB memory device 14 of computing machine 20, and the power supply USB-VCC of described USB memory device 14 is 5V, at this moment, can directly upgrade the content of described USB memory device 14 by computing machine 20.
