Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present invention, where the electronic device includes a telescopic mechanism, a differential trace on a Flexible Printed Circuit (FPC) of the telescopic mechanism is connected to an input terminal of a voltage comparator 101, and an output terminal of the voltage comparator 101 is connected to an application processor 102 on a motherboard of the electronic device;

the voltage comparator 101 is configured to detect an ESD interference signal caused by electrostatic discharge, and the application processor 102 is configured to process transmission data between the telescopic mechanism and the application processor according to the ESD interference signal detected by the voltage comparator 101.

The telescopic mechanism may be a telescopic component arranged in the electronic device, such as a telescopic camera, a telescopic screen, and the like, and taking the telescopic camera shown in fig. 2 as an example, the telescopic mechanism 20 is provided with an FPC21, and the FPC is provided with differential routing lines, which are usually multiple groups, for transmitting data between the telescopic mechanism and an application Processor of the electronic device, and usually one end of the telescopic mechanism is connected with a signal transmitter and the other end of the telescopic mechanism is connected with a signal receiver, so as to jointly form a Mobile Industry Processor Interface (MIPI) serial link.

As shown in fig. 3, in the conventional electronic device using the retractable camera, the high-speed serial data transceivers (HS-TX and HS-RX) and the low-power single-ended data transceivers (LP-TX and LP-RX) both perform data transmission on a set of differential wires, and the data flow on the differential wires is as indicated by arrows in the figure, where the differential wires are located on the FPC, one of the differential wires connects the low-power transmitter LP-TX and the low-power receiver LP-RX, and the other differential wire connects the high-speed transmitter HS-TX and the high-speed receiver HS-RX.

High-speed data can be recovered to a normal communication state in microsecond level under the condition of ESD transient interference, and once low-speed data is interfered, the low-speed data can be recovered to a normal state within several seconds, so that when the ESD transient interference is coupled to an MIPI link and received by a low-power receiver LP-RX, the sending state machine and the receiving state machine of the MIPI are inconsistent in step, communication errors are caused, under the condition, a receiving end is usually required to be restarted to recover a normal communication mechanism, and the recovery time needs several seconds, so that user experience can be seriously influenced.

In order to avoid the above phenomenon, in the embodiment of the present invention, as shown in fig. 1, a voltage comparator 101 is connected between a differential trace on the FPC of the telescopic mechanism and an application processor 102, so as to detect a time when the telescopic mechanism is subjected to ESD interference in an operating state through the voltage comparator 101, specifically, two ends of the differential trace are respectively connected to a control module 103 and an application processor 102 of the telescopic mechanism, an input end of the voltage comparator 101 is connected to the differential trace, an output end of the voltage comparator 101 is connected to the application processor 102, and the application processor 102 may be disposed on a main board of the electronic device. In addition, since the input impedance of the voltage comparator 101 is very high, the signal integrity of the detected channel is not substantially affected.

The operation principle of detecting ESD interference by the voltage comparator is described below with reference to fig. 4a and 4 b:

when the telescopic mechanism enters a working state and is in an extending state, the voltage comparator also enters the working state, the application processor records the initial state of the output voltage of the voltage comparator, if the initial state is low level, when ESD transient interference is coupled to the differential wiring on the FPC from the telescopic mechanism, the voltage of an input signal exceeds a threshold value V_HOr below the threshold V_LThe output state of the voltage comparator changes, and as shown in fig. 4b, the voltage comparator outputs a pulse, i.e. the output voltage V of the voltage comparator_OThe ESD interference can be confirmed by the application processor as long as the application processor detects that the voltage comparator outputs a high-level pulse or outputs a plurality of pulses under the condition of strong ESD static electricity.

In order to further improve the ESD interference resistance of the electronic device, the application processor may process transmission data between the telescopic mechanism and the application processor according to the detected ESD interference signal, for example, the transmission data transmitted by the telescopic mechanism and the application processor at the moment of detecting the ESD interference may be deleted, or the data may be retransmitted, instead of taking several seconds to wait for the restart of the signal receiving end, so as to avoid the phenomena of wire flashing, jamming, and deadlocking of the telescopic mechanism in the working state.

Optionally, two of the differential lines are respectively connected to a common-phase voltage comparator and an inverted-phase voltage comparator.

In this embodiment, in order to ensure that all ESD interference is detected more accurately, the two differential lines may be connected to a common-phase voltage comparator and an inverse-phase voltage comparator, respectively, so that when ESD interference is coupled to low-level data, the signal amplitude is smaller than V, and thus the signal amplitude is prevented from being smaller than V_HTherefore, the output level of the same-phase voltage comparator is not inverted, and the interference signal cannot be detected. If the inverted voltage comparator is connected to the differential trace, it can be determined that the ESD interference signal is detected when the output level of any one of the voltage comparators is inverted, and the application processor can be triggered to execute corresponding actions.

The following describes the embodiment by taking the telescopic mechanism as a telescopic Camera as an example, please refer to fig. 5, a Camera Module (CCM) in the telescopic Camera includes a low power consumption transmitter LP-TX and a high speed transmitter HS-TX, the CCM Module is connected to a motherboard of an electronic device through differential traces on the FPC, wherein, N groups of differential wires are arranged on the FPC, each group of differential wires comprises two differential wires, in the figure, only one group is illustrated, specifically, the low power consumption transmitter LP-TX and the high speed transmitter HS-TX are both connected to the low power consumption receiver LP-RX and the high speed receiver HS-RX in the PCBA motherboard through the same group of differential traces, and output ends of the low power consumption receiver LP-RX and the high speed receiver HS-RX are both connected to the application processor, so as to transmit the scan data sent by the CCM module to the application processor.

The voltage comparator is connected between the differential wiring and the application processor, specifically, one of the differential wiring of the same group is connected to the same-phase voltage comparator, the other differential wiring of the same group is connected to the reverse voltage comparator, the output ends of the same-phase voltage comparator and the reverse voltage comparator are both connected to the application processor, namely, the output ends of the same-phase voltage comparator and the reverse voltage comparator are respectively connected in parallel to the same-phase voltage comparator and the reverse voltage comparator at the low-power consumption receiver LP-RX end and the high-speed receiver HS-RX end, and the application processor is connected to the display module. Therefore, the application processor can confirm the moment of detecting the ESD interference signal by analyzing the output level change of the voltage comparator, take corresponding measures to correspondingly process the scanning data transmitted by the CCM module, and finally transmit the processed data to the display module for display.

It should be noted that, in practical applications, only one group of differential lines on the FPC of the telescopic mechanism may be connected to the voltage comparator, or each group of differential lines may be connected to the voltage comparator.

Optionally, the voltage comparator is disposed on the electronic device motherboard, that is, in order not to occupy the structural space of the telescopic mechanism, the voltage comparator may be disposed on the electronic device motherboard.

Optionally, the application processor is configured to:

In this embodiment, the application processor may determine whether ESD interference exists currently by analyzing a change of the output level of the voltage comparator when the telescopic mechanism is in the working state, and specifically, may determine that ESD interference exists at this time when the output level of the voltage comparator is detected to be inverted, for example, when the output level transitions from a low level to a high level.

In order to avoid data display errors caused by the interference affecting the transmission data between the telescopic mechanism and the application processor, in one mode, the error data transmitted at the corresponding time between the telescopic mechanism and the application processor may be deleted, and the error data may be replaced by historical transmission data, and the processed data may be finally output and displayed, wherein the historical transmission data may be data transmitted at the latest time between the telescopic mechanism and the application processor, such as transmission data at the previous time when the ESD interference is detected. It should be noted that, because ESD interference is usually nanosecond, it only interferes with the transmission data between the telescopic mechanism and the application processor and at short time, so after the historical transmission data is used to replace the error data display, it is difficult for the user to distinguish the change by naked eyes, and thus the visual experience of the user is not affected by adopting the scheme.

In another mode, a control signal may be sent to a control module in the telescopic mechanism when ESD interference is detected, so as to trigger the control module to retransmit data to the control module, taking a telescopic camera as an example, the application processor may send a CTR control signal to the CCM module immediately when ESD interference is detected, the CCM module retransmits data to the application processor immediately after receiving the signal, where the data includes a sending state machine, scanning data, a receiving state machine, and the like, and the application processor may transmit the data retransmitted by the CCM module to the display module for display.

Optionally, the telescopic mechanism is a telescopic camera;

the application processor is to:

deleting the nth data in the mth field scanning data transmitted by the CCM module in the telescopic camera, wherein the nth data in the mth field scanning data is scanning data corresponding to the moment when the ESD interference is detected, m is an integer greater than 1, and n is an integer greater than or equal to 1;

and replacing the nth data in the mth field scanning data with the nth data in the (m-1) th field scanning data.

In this embodiment, the telescopic mechanism is a telescopic camera, and a CCM module of the telescopic camera can generally transmit more than 60 fields of scanning data to the application processor every second, where 1 field of scanning data includes hundreds of rows of data, that is, the scanning time of each row of data is about tens of microseconds, and ESD interference is usually in the order of nanoseconds, so that one ESD interference can only affect data of a certain 1 row in a certain 1 field of data transmitted by the CCM module.

Therefore, when the application processor detects the ESD interference, the application processor may lock a corresponding line data in the corresponding field scan data transmitted by the CCM module at the time when the ESD interference is detected, that is, an nth line data in the mth field scan data, and the line data is the data transmitted by the CCM module at the time when the ESD interference exists, delete the line data to control the interfered error data of the line not to be displayed in the display module, and may replace the line data with the same line data in the previous field scan data, that is, replace the nth line data in the mth field scan data with the nth line data in the m-1 field scan data, and finally transmit the replaced data to the display module for display, so as to avoid the problems of the telescopic camera, such as flashing or jamming due to the ESD interference during the shooting process.

Optionally, the telescopic mechanism is a telescopic camera;

the application processor is to:

and sending a control signal to a CCM module in the telescopic camera to enable the CCM module to start transmission from m +1 field scanning data, wherein the m field scanning data is scanning data corresponding to the moment when the ESD interference is detected, and m is an integer greater than or equal to 1.

In this embodiment, when the telescopic mechanism is a telescopic camera, in view of the above similar principle, when the application processor detects ESD interference, it may also be configured to send a control signal to the CCM module in the telescopic camera to trigger the CCM module to start transmission from the m +1 th field of scan data, that is, transmission of the m-th field of scan data transmitted by the CCM module at a time when the ESD interference exists may be skipped, so as to avoid displaying interfered error scan data in the display module, and by triggering transmission of the next field of scan data, phenomena such as flashing or jamming caused by interference in a shooting process may be avoided.

In this embodiment, a voltage comparator is introduced into the electronic device including the telescopic mechanism to detect the ESD interference signal, so that data transmitted by the telescopic mechanism can be processed according to the detected ESD interference signal, thereby preventing the phenomena of data display blocking, jamming and the like caused by restarting of a receiving end, and further improving the ESD interference resistance of the electronic device.

step 601, determining that the ESD interference is detected under the condition that the telescopic mechanism is in a working state and the output level of the voltage comparator is detected to be converted.

Step 602, deleting error data transmitted by the telescopic mechanism and the application processor at the moment when the ESD interference is detected, and replacing the error data with historical transmission data; or sending a control signal to a control module in the telescopic mechanism, so that the control module retransmits data.

Optionally, the telescopic mechanism is a telescopic camera;

Optionally, the telescopic mechanism is a telescopic camera;

the control signal is transmitted to the control module in the telescopic mechanism, so that the control module retransmits data, and the method comprises the following steps:
