The terminal server 300 includes an abnormal location analysis module 301.
The strain sensor 201 is used for collecting strain information of an object to be measured and transmitting the strain information to the internal demodulation system 202. For example, the strain sensor 201 is an FBG strain sensor.
Wherein the object to be measured comprises a component of the electronic device 200 or a component of another electronic device. For example, the object to be measured is a motherboard inside the electronic device 200, and the at least one strain sensor 201 tests strain information on the motherboard surface in real time. Therefore, the abnormal position detection system provided by the embodiment of the invention is suitable for the self-monitoring service scene of the terminal equipment such as a mobile phone, a tablet or a desktop, and the like, and is also suitable for the quick maintenance service scene of the abnormal terminal equipment.
The internal demodulation system 202 is configured to receive strain information sent by the at least one strain sensor 201, and send the strain information of the at least one strain sensor 201 to the damage identification module 203. The internal demodulation system 202 receives the strain information collected by the at least one strain sensor 201, and sends the processed strain information to the damage identification module 203.
The damage recognition module 203 is configured to obtain a detection result of the object to be detected according to a damage recognition algorithm and the strain information.
The damage identification algorithm comprises a strain differential damage identification algorithm and/or a PCA reconstruction damage identification algorithm. For example, the damage recognition algorithm can judge the position in the main board where damage is most likely to occur in real time.
The strain differential damage identification algorithm is used for locating the position of the FBG strain sensor by searching the maximum value of the strain differential difference between the current strain and the previous moment, so as to judge the damage position or the possible weak point. Because the FBG strain sensor and the surface of the object to be measured have a strain transmission process, the strain rate is kept substantially unchanged when the object to be measured is not abnormal; however, when the object to be measured is damaged, the strain transmissibility from the surface of the object to be measured to the FBG strain sensor is changed, so that the strain rate is suddenly changed.
A certain number of FBG strain sensors are arranged on the surface of an object to be detected (a main board and the like), test data of one part of the FBG strain sensors are used as input strain, and test data of the other part of the FBG strain sensors close to a vulnerable position are used as test strain. Reconstructing a strain field of the input strain through a PCA reconstruction damage identification algorithm to obtain a reconstruction strain value of the target position; comparing the reconstructed strain value with the value of the test strain at the same position to obtain an abnormality index, thereby defining damage and identifying an abnormality position.
According to the embodiment of the invention, the damage identification algorithm is built in the electronic equipment 200, so that the problem position of the whole machine can be positioned, the maintenance period of the product is shortened, and the repair function is accelerated.

The damage recognition module 203 is further configured to not send the detection result to the abnormal position early warning module 204 and the abnormal position analysis module 301 if the detection result does not include abnormal position information; if the detection result includes abnormal position information, the detection result is sent to the abnormal position early warning module 204 and the abnormal position analyzing module 301.
According to the embodiment of the invention, the damage occurrence position is positioned according to the damage identification algorithm and the strain information, so that the maintenance efficiency is improved.
For example, if the detection result includes abnormal location information, the electronic device 200 transmits the detection result to the terminal server 300 through a wifi signal.
The abnormal position early warning module 204 is configured to generate abnormal reminding information according to the abnormal position information, and send the abnormal reminding information to the screen 205. The screen 205 is used to display abnormality alert information. In the process of using the electronic device 200 or other electronic devices, once the device fails, the electronic device 200 prompts the user for maintenance at the first time, and the user can perform data transfer and storage services in advance. For example, the mobile phone carries out mobile phone health early warning in advance for 5 minutes to remind the user, and the user carries out important operations such as data storage and the like, so that the user loss is reduced.
Alternatively, the electronic device 20 is installed with an application for detecting an abnormal position, i.e., a detection application. The screen 205 is also used to display an interface for the detection application. For example, the screen 205 displays the detection result of the object to be detected, the detection result including the abnormal position point.
The abnormal position analysis module 301 is configured to generate repair service information according to the abnormal position information, and send the repair service information to the screen 205. The screen 205 is used to display maintenance service information. When a user uses the electronic device 200 or other electronic devices, once the device fails, the electronic device 200 transmits the failure problem, that is, the abnormal location information, to the terminal server 300 of the manufacturer, and the terminal server 300 analyzes the abnormal location information to obtain maintenance service information. Specifically, the terminal server 300 decides to provide the upper gate maintenance service or give the user maintenance guide opinion based on the abnormal location information.
Wherein the maintenance service information includes the door-to-door maintenance service information or the user maintenance guide opinion information.
