The voltage level adjustment module (10) is electrically connected to the first transmission end 1344756 112 'used to touch the first transmission end 112 - the output voltage level is over the voltage level detection pole group 13G is electrically secret The second transmitting end m is configured to detect the input voltage level Vin of the second transmitting end 114. And the control circuit 14 is connected to the voltage level. The Zhouwang module 120 and the voltage level detecting module 13〇 are used to control the voltage level adjusting module 120 to adjust the output level v〇ut, and determine the electronic device according to the output level leakage and the input voltage level Vin. The type of ls〇. In this embodiment, the control circuit 140 may be a ten-central processing unit (cemer, which can achieve the purpose of detecting the type of the electronic device (9) via the execution side control software. However, the present invention is not limited thereto. - In practice, that is, the control circuit 14 can also be implemented by a hard square wire. Please note that since the detection circuit of the actual wipe is used to detect and measure whether the electronic device 150 is one China AC adapter's description from the prior art shows that the Chinese AC charger connector interface uses a universal serial bus (Universal Serial Bus, so 'detection circuit contact, can Integrated into a mobile phone, a PDA, or any portable electronic device, and the transmission interface 110 in the detection circuit is -USB interface 'however' this is only for _, not for Limitations of the invention. The following describes the operation mode of the detection circuit, and in order to facilitate the description of the technical features disclosed in the present invention, a D+ terminal of the brain interface is used as the first transmission terminal 112, and The d-end is used as an embodiment of the second transmission end 114. However, this is for illustrative purposes only and is not a limitation of the present invention. For example, in other embodiments, the first transmission end 112 is The second transmitting end 114 can be the D_ terminal and the } end of the clear interface respectively. The 1344756 ^ 6 portable electronic device transmission interface 110 is connected to the electronic device 15 when the 'transport interface 110 (USB interface) in the VBUS end The voltage level ^(10) ' is raised from a low voltage level to a high voltage level and maintained at a high voltage level. Therefore, whether the voltage level Vbus of the user terminal is located by the home interface 110 (USB interface) - High voltage level can be used to know whether the current transmission interface ιι〇 is connected to the electronic device 150'. Since the general knowledge of the field towel should be easy to understand how to make the transmission interface 11G is the electronic device i5Q (ie, Detecting whether the voltage level i of the VBUS terminal in the Lu transmission interface 110 (Cong interface) is located in a high-voltage quasi-magic green, shame, for the sake of the contents of the content, the detailed description is omitted here.

Then, the control circuit 14 controls the voltage level adjustment module 12 The output voltage level Vout of the first transmission terminal U2 (D+ terminal) in the transmission interface 110 (USB interface) is increased to a high voltage level % (hours | JT2), and the voltage level detection module 130 is simultaneously removed. It will detect the input voltage level vin of the second transmission terminal ιΐ4 (D-terminal) in the transmission interface 11〇(聪 interface). In this embodiment t (3) can be a pull-up circuit. (4) The power (9) is - China AC charger 'When the output of the first transmission terminal U2 (d+ terminal) • The voltage level Vout is raised to the high voltage level Vh by the voltage level adjustment module 12〇, = The input voltage level Vin of the transmission terminal m (D-terminal) is also upgraded to the high-power scale vh due to the internal short-circuit relationship of the Chinese AC charging person. Therefore, the voltage level detecting module 130 detects The input voltage level p to the second transmission terminal 114 (〇_ terminal) should be equal to the output voltage level v(10) of the first transmission terminal 112(7)+ terminal) (to the reliance level Vh). Thus, the control circuit 14G The electronic device (9) is correctly identified as a Chinese AC charger. 1344756 Figure 3 is a timing diagram of the signal waveform on the transmission interface nG (Cong interface) when the portable electronic device is connected to one of the non-Chinese AC chargers, as shown in Figure 3, when the portable When the electronic device is connected to the electronic device 15 (time 4), the electric bust Vbus of the side end (not shown) of the transmission interface 110 ((10) interface) is raised from the low voltage level to a high voltage level. , control circuit _ this can be known that the _ sub-device is connected to an electronic device _%, then the 'control circuit 140 will (4) electric county level woven volume 12 () nuclear upgrade transmission interface U0 (USB interface) The output voltage level of the first transmission terminal 112 (d+ terminal) leaks to - the high power fresh position Vh (_ 5), _, the Xia level system module 130 will remove the transmission interface 110 (Cong interface) in the second The transmission terminal u4 (d_ terminal) of the input = voltage level Vin. Since the electronic device 15 is not a Chinese AC charger, the output voltage level of the field-transmitter terminal 112 (〇+ terminal) is raised to the high voltage level % by the voltage level adjustment module 120, and the second The transmitting end 114 (D-end) ^ input electric fresh bit Vin is not raised to the high voltage level %, therefore, the electric=level detecting module 130 detects the second transmitting end n4 (D_ The input voltage of the terminal) is not equal to the output level of the first transmission terminal (called the D+ terminal).
