In a particular embodiment of the invention, control system 20 is a chip set, although the invention is not limited thereto.

Please refer to FIG. 3 to FIG. 5 together, and please continue to refer to FIG. 1 and FIG. 2 . FIG. 3 is a flow chart showing the steps of the method for correcting the communication stability between the external device and the external device. The steps shown in FIG. 3 will be sequentially described below with reference to FIG. 1, FIG. 2, FIG. 5 and FIG. It should be noted that the following describes the method for correcting the communication stability between the present invention and the external device, but the method is not limited to the electronic device 1 described above.

First, step S1 is performed: determining, according to an execution instruction, whether the processing unit receives the transmission signal transmitted by the external device.

In one embodiment of the invention, the activation of the correction system 41 begins with the user's operation. In detail, when the user connects the external device 90 to the insertion slot 10 of the electronic device 1, if it is found that the display surface (not shown) of the electronic device 1 does not appear, the external device 90 has been connected to the electronic device 1. If the content of the data stored in the external device 90 cannot be displayed on the display surface of the electronic device 1, it indicates that the signal transmission between the two devices is abnormal. At this time, the user can input an execution instruction through the touch device 30 to control the processing unit 10 to execute the correction system 41. Once the correction system 41 is executed, the abnormality detection module 412 of the correction system 41 determines whether the processing unit 40 has received the transmission signal from the external device 90 according to the execution instruction to confirm that the signal transmission of the two devices does abnormally occur.

Then, step S2 is performed: the signal voltage strength when the external device transmits the signal is increased.

As shown in FIG. 4, it is a settable voltage value of the signal voltage strength when the external device transmits a signal, and the settable voltage value range is determined by Intel Corporation. Generally, when the electronic device 1 is shipped from the factory, the manufacturer selects a voltage value as the preset voltage when the electronic device 1 and the external device 90 transmit signals, that is, after the electronic device 1 is turned on, the voltage is regarded as The preset voltage when communicating with the external device 1. However, when the user connects the external device 90 to the docking slot 10 of the electronic device 1, if the two devices cannot transmit the signal smoothly, the possible reason is that the transmission line impedance connecting the two is too large (because the non-factory transmission line is used) The transmission signal transmitted by the external device 90 cannot be smoothly transmitted to the electronic device 1. Therefore, in step S1, if the processing unit 40 has received the transmission signal from the external device 90, the correction system 41 stops execution. On the other hand, if the processing unit 40 fails to receive the transmission signal from the external device 90, the signal adjustment module 413 of the correction system 41 will increase the signal voltage intensity when the external device 90 transmits the signal, for example, the signal voltage. When the initial strength setting is 420 millifors (mV), it will be increased to 430 millifors (mV).

Step S3 is performed to determine whether the processing unit receives the transmission signal from the external device.

After the step S2 is performed, the correction system 41 determines whether the processing unit 40 receives the transmission signal from the external device 90 within a certain period of time to confirm whether the processing unit 40 can be properly connected to the external device after the signal voltage strength is increased. The device 90 performs signal transmission. If the transmission is normal, the correction system 41 stops execution; otherwise, if the signal transmission has not been performed normally, step S4 is performed.

Step S4 is performed to determine whether the signal voltage strength reaches a set maximum value.

In an embodiment of the present invention, after the signal voltage strength when the external device 90 transmits the signal is increased, if the electronic device 1 still cannot perform the signal transmission with the external device 90, the external device 90 can be selected to transmit the signal. The voltage intensity of the signal is increased, or when the signal voltage strength cannot be increased, the threshold value of the disconnection voltage when the processing unit 40 and the external device 90 are connected is increased; therefore, the correction system 41 is used before the signal voltage strength is increased. It will first determine if the signal voltage strength has been adjusted to the set maximum.

If the signal voltage strength has not reached the set maximum value, steps S2 and S3 are repeatedly performed; if the signal voltage strength has reached the set maximum value, step S5 is performed.

Finally, step S5 is performed: the threshold value of the disconnection voltage when the processing unit establishes a connection with the external device is increased.

As shown in FIG. 5, it shows the waveform of the transmission signal transmitted through the insertion slot. As described above, in the embodiment of the present invention, the insertion slot 10 of the electronic device 1 is a universal sequence bus; the line D+ in FIG. 5 represents the universal sequence bus positive data signal, and the line D- represents the universal sequence. Bus line negative data signal. In general, when the external device 90 and the electronic device 1 are normally connected, the voltage level of the positive data signal is less than the critical value of the disconnection voltage (ie, the line Vref shown in FIG. 5); in other words, the voltage of the positive data signal. When the level exceeds the critical value of the disconnection voltage, the electronic device 1 will be disconnected from the external device 1, and naturally, the signal transmission with the external device 90 cannot be performed. Therefore, when the signal voltage strength of the external device 90 is increased to the maximum set value after the external device 90 is transmitted, the electronic device 1 cannot normally transmit signals to the external device 90. The reason may not be that the signal voltage strength of the transmitted signal is insufficient. Rather, the voltage level of the positive data signal caused by the inferior transmission line exceeds the critical value of the disconnection voltage, resulting in unstable connection. Therefore, when the signal voltage intensity when the external device 90 transmits the signal is adjusted to the maximum (that is, adjusted to 450 milli Ford as shown in FIG. 3), and the electronic device 1 cannot perform signal transmission with the external device 90, the correction system is The disconnection voltage adjustment module 414 of the 41 is the threshold value of the disconnection voltage when the connection processing unit 40 and the external device 90 are connected to each other, thereby attempting to enable the electronic device 1 by eliminating the unstable condition of the connection. The external device 90 performs signal transmission.

The above-mentioned disconnection voltage threshold has the same preset initial value as the signal voltage strength when the external device 90 transmits the signal, and the initial settings of both are set when the manufacturer ships. Through the correction system 41 of the present invention, the cutoff voltage threshold value and the signal voltage strength can be dynamically adjusted to be equipped with external hardware according to different qualities.

It should be noted that the method for improving the communication stability between the present invention and the external device is not limited to the order of the steps of the above embodiments, and the order of the above steps may be changed or omitted as long as the object of the present invention can be achieved. For example, the method for correcting the communication stability between the present invention and the external device may also first increase the threshold value of the disconnection voltage, and then increase the signal voltage strength when the external device 90 transmits the signal; or perform the high-power-off only separately. Line voltage threshold or increase signal voltage strength.

To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible. It should be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the invention is intended to be limited by the scope of the claims.
