Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
As shown in Figure 1, existing connector passes through all on it that a corresponding matching unit links to each other in metal port and the handheld device.For realizing the present invention, need the structure of existing connector is carried out following modification: as shown in Figure 2, use port to first port and second port respectively with corresponding matching unit on port the 3rd port and the 4th port are linked to each other, and with first port and second port at the inner short circuit of connector, thereby constitute a loop in that this connector is inner.So, this connector and this matching unit have just constituted one " connector matching structure ".In addition, this handheld device inside also comprises control module and fault Tip element, and this control module, fault Tip element and matching unit can but be not limited to be integrated on the central processing unit.
As shown in Figure 3, after testing process starts, control module sends an electric signal to above-mentioned matching unit, and matching unit is exported this electric signal by the 3rd port on it (or the 4th port) to this connector, and whether detection has the electric signal input on the 4th port (or the 3rd port), if do not have, then think above-mentioned connector and this matching unit loose contact, and this result is sent to control module; Otherwise, electric signal is sent to control module, same or similar by the control module similarity of electric signal and the electric signal of output of its input relatively as if the two, as shown in Figure 4, think that then above-mentioned connector contacts well with this matching unit; Otherwise, as shown in Figure 5, think above-mentioned connector and this matching unit loose contact.
When detecting connector and this matching unit loose contact, this control module can be by the concrete discernible signal of fault Tip element utilization to User Alarms, type of alarm can but be not limited to be: LCD text prompt, auditory tone cues, light flash prompting etc.
Testing process can start automatically when handheld device is started shooting, regularly start or be manually booted by the user.
Certainly, it is right that a plurality of ports can be set on the matching unit, make this matching unit can be connected with other connector that above-mentioned connector has a same structure.As shown in Figure 6, connector 1, connector 2 and connector 3 are connected to the different port of matching unit to last, control module can be gone up the right feedback information of different port by its of matching unit feedback, determines the connection status of each connector, thus definite location of fault.
Further be illustrated with an application example of the present invention below.
Certain mobile phone has camera function.Behind the body drop impact, camera function can't use.Cause the hardware reason of this phenomenon to have two kinds: 1, image sensor cell damages; 2, image sensor cell and central processing unit loose contact.By implement said method on the image sensor cell pin, whether the physical connection that the central processing unit of mobile phone can detect image sensor cell by the input signal that reads the port centering that links to each other with image sensor cell on it is normal.When CPU (central processing unit) is judged to be the loose contact fault, can notify the user by fault alarm.This alerting signal can be the discernible forms of user such as sound, image, such as buzzer call or pilot lamp flicker etc.So user or maintenance personal can be to fault anticipations to some extent, and implement relative measures.
Equally, implement said method, also can carry out detection of connectivity and information feedback other functional unit by each other functional unit on this mobile phone.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
