Alternatively, the power supply module 105 can be a battery, such as a rechargeable battery, a replaceable battery, or other type of device capable of supplying power.

Since the mobile device 110 is separately provided with an anti-lost device 100, it is likely to cause inconvenience to the user. For example, the user is only used to carrying the mobile device 110 and forgets to carry the anti-lost device 100, so that the anti-lost function cannot be enabled. Therefore, preferably, the anti-lost device 100 may include the function module 104 to implement a certain function of the anti-lost device 100, that is, to cooperate with a specific function of the mobile device 110, such as a wired headset, a large-capacity battery, a mobile power source, a large-capacity backplane battery. , battery holder, wireless router (MiFi), charger, car charger, data cable, cable, charging cable, mobile payment card reader, u shield, u disk, mobile hard disk, stationery, wireless mouse, key, electronic cigarette At least one of the devices. For example, current mobile devices face high power consumption problems due to increased screen and processing power. In normal use, they usually only last for one day, so users often carry two batteries, a large-capacity backup battery or a charger. In order to charge mobile devices in time. When the function module 104 is implemented as a large-capacity battery, it can not only solve the function of the user carrying the anti-lost device 100, but also serve as the power supply of the anti-lost device 100, so as to ensure safe and long-term power supply for the anti-lost device 100, and improve the power. User's convenience. The anti-lost device 100 according to the present invention can also be integrated in a USB flash drive, a key (including but not limited to a car key, a door key, etc.), a stationery (e.g., a pen) to facilitate the user's carry-on.

Preferably, the anti-lost device 100 further includes a reminder module 103 for promptly sending a reminder signal to the user through the anti-lost device 100 itself if the mobile device 110 is stolen or lost. When the mobile device 110 is stolen or lost, the mobile device 110 may be separated from the anti-lost device 100 by a certain distance, so that the wireless communication connection between the communication module 114 of the mobile device 110 and the wireless module 102 of the anti-lost device 100 is broken. When the wireless connection state (eg, connection strength, etc.) is below a certain preset value, the wireless module 102 within the anti-lost device 100 is triggered to send a control command for alerting the user that the mobile device 110 may be lost or stolen. In this embodiment, the reminding module 103 receives a control command sent by the wireless module 102 to remind the user that the mobile device may be lost or stolen, and is used to send a signal prompting the user.

The reminder module 103 may include, for example, at least one of the sound module 1031, the vibration module 1032, and the light emitting module 1033 for emitting at least one of sound, vibration, and light signals, alone or in combination. For example, the reminder module 103 may include only the sound module, and promptly emit a sound reminding signal to the user in the event that the mobile device 110 is stolen or lost. Alternatively, the reminding module 103 may include a sound module and a vibration module, and simultaneously emit a sound and vibration reminding signal to the user in the event that the mobile device 110 is stolen or lost, to prevent the user from being noisy in the outdoor environment. In the case of hearing, the sound is not heard and the situation of being stolen or lost is not discovered in time. The three alert modules shown in the figures are merely illustrative and may include other types of modules that implement the alert function, in addition to those shown herein.

Figure 2 is a block diagram showing the product of an anti-lost device implemented as an anti-lost mobile power source according to the embodiment of Figure 1. As shown in FIG. 2, the anti-lost device is implemented as an anti-lost mobile power source 200 in this embodiment. The functional modules in the mobile power source 200 according to the present embodiment are implemented as a charge and discharge control module 204 and a battery 205. Preferably, battery 205 is a large capacity battery, such as 5000 mAh - 15000 mAh. The mobile device 210 can be connected to the mobile power source 200 when it is found to have insufficient power during use, and is charged by the battery 205 and the charge and discharge control module 204. The charge and discharge control module 204 manages the charging and voltage conversion of the battery 205. When the battery 205 has insufficient power, it can be connected to the AC power source to charge the battery 205 through the charge and discharge control module 204. The charge and discharge control module 204 and the battery 205 can also power the wireless module 202 and communicate status information of the battery 205.

In the working state of the anti-lost monitoring, the wireless module 202 in the mobile power source 200 and the module with the same wireless connection protocol of the mobile device 210 establish a two-way wireless connection capable of transmitting and receiving wireless signals, and establish communication after the connection in the mobile device 210. Module 214 can exchange associated control information and wireless connection status with wireless module 202 within mobile power source 200. When the mobile device 210 is stolen or lost, the mobile device 210 is more than a certain distance from the mobile power source 200, such that the wireless communication connection between the communication module 214 of the mobile device 210 and the wireless module 202 of the mobile power source 200 is disconnected, or When the wireless connection state is lower than a certain preset value, the wireless module 202 in the triggered mobile power source 200 sends a control command to the reminder module 203. The reminding module 203 further triggers at least one of the sound module 2031, the vibration module 2032 and the lighting module 2033 controlled by the alarm module 203 according to the setting, respectively, or in combination, and sends a reminding signal such as a sound, a vibration, and/or a light reminder to the user. In the event that the user is prompted that the mobile device 210 has exceeded a certain distance of the user, a stolen or lost condition may have occurred. Preferably, the mobile device 210 can also issue a preset prompt according to the wireless connection status, or protect and/or encrypt/decrypt data in the mobile device 210 to protect the data of the mobile device 210. The communication module 214 in the mobile device 210 can also issue control commands to the wireless module 202 in the mobile power source 200, and the wireless module 202 controls the charge and discharge control module 204 or the reminder module 203 to perform corresponding operations.

According to still another embodiment of the present invention, the anti-lost device may also be implemented as a cable, wherein the cable module is configured to provide a power path and/or a data signal path for connecting the mobile device to charge it, and/or Connect to other devices to transfer data. The cable module is preferably a four-core cable structure that provides positive and negative power paths and data signal paths, respectively. For example, a four-wire cable structure suitable for standard USB data and power transmission can be used, that is, two cables are used to transfer data between the mobile device and the computer, and the other two cables are used in the mobile device. Connected to The power supply signal is transmitted when the device is being charged.

The anti-lost device according to the present invention can be automatically turned on or off for a familiar location or location in conjunction with the control of the mobile device, to prevent the user from forgetting to turn on the anti-lost monitoring function in an unfamiliar environment, or to enable the anti-lost monitoring function in the familiar environment. Waste and unnecessary harassment of users. The anti-lost monitoring function refers to that the anti-lost device establishes a two-way wireless connection between the wireless device and the mobile device by using a wireless network, and the wireless connection state between the two is disconnected or lower than a preset. In value, the anti-lost device sends and/or receives control commands for prompting the user that the mobile device may be lost or stolen.

For example, when the user returns home and takes the mobile device to another room, the distance between the anti-lost device may exceed the set threshold, causing the anti-lost device to mistake the mobile device for being stolen. Obviously, here There is no need to monitor the anti-lost alarm in this case. In another case, since the wireless module 102 in the mobile anti-lost power supply 100 needs to periodically perform signal interaction with the communication module 14 in the mobile device 100 to determine whether a certain distance is exceeded, the mobile device 1 1 0 may be Stealing or losing, so whether it is the mobile anti-lost power supply 100 or the mobile device 1 10 itself itself needs to consume a certain amount of power to maintain this monitoring condition, which will affect the mobile device 1 10 and the mobile anti-lost power supply 100 Standby time, which is inconvenient for the user. In particular, the environmental monitoring function is suitable for detecting a loss or anti-theft situation of the mobile device when the user is in an outdoor environment or an unfamiliar environment, and can automatically turn off the mobile anti-lost when the user is in a familiar scene (such as in a home or an office). Monitoring capabilities of devices and/or mobile devices to conserve power and reduce disruption to users. When the user's environment changes, the change of the location information can be detected in time to detect the occurrence of the change, thereby automatically turning on the monitoring function of the anti-lost device in time.

In addition, location information that is familiar to more than one user may have been recorded in a familiar environment or scene in which the user is located. For example, when a user is in the office, there may be more than one familiar Wi F i network in the office. The user may switch to a different familiar Wi F i network due to walking in the office. In this case, although the location information of each acquired mobile device may be different, since it is a familiar location that the user has defined, there is no need to turn on the anti-lost monitoring function of the anti-lost device.

Optionally, in an environment where the anti-lost device and the mobile device are recognized as being familiar, the function of the wireless connection state between the anti-lost device and/or the mobile device can be maintained, and the anti-lost device and/or the mobile device can be turned off. Reminder or alarm function of the device to avoid harassing users in a familiar environment.

The identification of the environment needs to be based on the identification of the location and environment that the user has visited in the past, which is achieved in the present invention by the location database 17 in the mobile device described above. The recorded user location includes, but is not limited to, a location that is located by GPS, by detecting the MAC address of the connected Wi F i router, thereby determining the network connection status or location, and detecting the mobile communication. The current cell location of the network is used to determine the network connection status or location of the network.

When the user turns on the familiar environment identification function, the location database needs to be initialized and updated. The specific method steps are shown in Figure 3.

In Figure 3, step 31 0, the user turns on the environment recognition function.

Step 320: Determine whether a location database already exists in the current existing mobile device. If yes, proceed to step 330. If it is determined that there is no location database, it may be that the user first uses the environment identification function, and it is necessary to proceed to step 340 to create a new location database before proceeding to step 330.

Alternatively, the user may use the environment recognition function for the first time due to the replacement of the new mobile device or the operating system of the re-updated mobile device. However, users may have built and saved location databases in the past. In this case, an optional step 325 is also included, which allows the user to synchronize the previously saved location database to the local through the cloud.

At step 330, location information that has been recorded by the mobile device but not stored in the location database is retrieved. For example, users may have visited some new places but are considered familiar to the user, such as moving users, changing new office locations, friends, and so on. The method according to the invention can retrieve these new locations that have been recorded by the mobile device, such as the location of the location by GPS, the location determined by detecting the MAC address of the connected Wi F i router, by detecting the current cell of the mobile communication network. Position to determine position, etc.

Optionally, the unsaved location above also includes the location where the user is currently located. You can retrieve the user's current location for recording. For example, the location determined by the MAC address of the GPS and/or Wi F i router, and the current cell location of the mobile communication network.

At step 350, the user is prompted to mark these new locations as familiar environments and thereby save them in the location database. If the user selects yes, then go to step 360 to save these new locations; if not, the method ends. Alternatively, the user may also select some of these locations for recording.

4 is a flow chart showing a method for identifying an anti-lost monitoring function of an automatic shutdown anti-lost device based on a familiar environment scenario in accordance with the present invention. The specific steps are as follows.

Step 400: Determine whether the user has enabled the automatic environment identification function. If it is on, go to step 41 0, otherwise wait until the user turns on.

Step 41 0. Regularly obtain the location information of the mobile device. According to the invention, the mobile device 1 10 obtains location information by means of the location module 1 16 as described above. The location information includes, but is not limited to, information obtained by the GPS chip, the Wi F i router MAC address, the wireless communication network, etc., which can be used to identify the location or scene in which the mobile device is located. Preferably, the frequency of periodic acquisition is once every 5 minutes. Users can also set the interval time according to their needs.

At step 420, the location or scene acquired this time is recorded with the location recorded in the location database. Information is compared. As described in the method of FIG. 3, the location recorded in the location information base may be a familiar scene previously set by the user, such as a home, an office, or the like. Each scene information corresponds to at least one location information, for example, may correspond to GPS information, or MAC address information of a wireless router, and the like.

In step 430, it is determined in this step whether the location acquired this time is the same as any of the locations recorded in the location database. If yes, the process proceeds to step 440. Otherwise, the process proceeds to step 450.

In step 440, an instruction is issued to the anti-lost device and/or the mobile device, and the monitoring function and/or the reminding function of each and/or the other party is turned off or disabled. Returning to step 410, the location of the mobile device is continued to be monitored for judgment.

In step 450, it is determined that it is an unrecorded unfamiliar location, indicating that the user has left the current location, and then issues an instruction to the anti-lost device and/or the mobile device, and turns on the monitoring function and/or the reminding function of each and/or the other party. . Returning to step 410, the location of the mobile device continues to be obtained for monitoring.

Preferably, the anti-lost monitoring function between the anti-lost cable and the mobile device may be a bidirectional control command, that is, when it is found that entering the familiar environment, the anti-lost cable and the mobile device pass anti-lost The wireless module of the cable and the communication module of the mobile device issue control signals to each other to turn off or disable the monitoring function and/or the reminding function of the respective and/or the other party; and when entering an unfamiliar environment, the anti-lost cable and the mobile device The control module and/or the reminder function of each and/or the other party can be enabled by sending a control signal to each other through the wireless module of the anti-drop cable and the communication module of the mobile device.

Optionally, before or at the same time as step 450, step 445 may be further included, and the acquired new location is recorded to provide a selection decision to the user. The user can optionally define the recorded new location as a familiar scene and record it in the location repository for later use. Specifically, the mobile device can prompt the user to let the user choose whether to record the new strange location as a familiar location. This occurs, for example, in the scenario where the user first uses the anti-lost device. When the user chooses to record the new unfamiliar location as a familiar location, the location information is stored in the location database of the mobile device as familiar location information for later identification when the user re-enters the location.

In addition to the control signal from the mobile device to automatically turn off and start the anti-lost function of the anti-lost device, the user can also set the anti-lost device to automatically turn on or off during a special period of time. For example, you can set the anti-lost device to automatically turn off the anti-lost function between 11:00 and 7:00 in the day-to-day period to prevent the anti-lost device from turning on the anti-lost function at night. Optionally, the user can also set a special schedule, such as binding with a mobile device's calendar function or schedule reminder, email reminder, etc., in the meeting displayed on the calendar or During other required time periods, the control signal is automatically sent to the anti-lost device, the anti-lost function of the anti-lost device is turned off, and the anti-lost device is re-opened after the schedule ends.

As described in the foregoing embodiment, in the anti-disaster operation mode of the mobile device according to the anti-lost device of the present invention, the wireless module in the anti-lost device and the module with the same wireless connection protocol in the mobile device are established. A two-way wireless connection that can send and receive wireless signals, and exchanges related control information and wireless connection status after establishing a connection. When the mobile device is stolen or lost, the distance between the mobile device and the anti-lost device exceeds a certain threshold. By setting the threshold, it can be determined whether the mobile device has left the set distance, that is, the The possibility of stealing or losing. When it is detected that the distance exceeds the threshold, the wireless communication connection or disconnection between the communication module of the mobile device and the wireless module of the anti-lost device, or the wireless connection state, such as the signal strength or the connection rate is lower than a certain pre- When the value is set, it is determined that the mobile device has been stolen or lost, and the corresponding subsequent signal is triggered. The trigger can also be implemented by sending a specific instruction to the communication module of the anti-lost device. In addition to the reminder module in the anti-lost device described above to issue a corresponding reminder signal or alarm signal, the following operations may also be performed in the following manners.

Protect data in mobile devices, such as erasing, locking, and so on. When the wireless communication status between the communication module of the mobile device and the wireless module of the anti-lost device has been determined to be lost or reaches a certain threshold condition and is determined to be stolen or lost, the device may be moved by the anti-lost device. The device sends a control signal, so that the mobile device directly enters the security mode that is provided by the system or preset by the user. In this security mode, it can be set to automatically lock the mobile device by the control signal, for example, by a user-preset password. Preferably, the data in the mobile device may be completely erased after the input password error reaches a predetermined number of times to prevent the theft party from maliciously acquiring data in the mobile device.

According to the present invention, the anti-theft or loss determination of the mobile device is mainly performed by the wireless module in the anti-lost device and the module with the same wireless connection protocol in the mobile device establishing a two-way wireless connection capable of transmitting and receiving wireless signals, and exchanging relevant control information and Wireless connection status. Alternatively, additional decision rules can be added to more accurately determine the loss or theft status of the mobile device. For example, after the wireless connection state of the anti-lost device and the mobile device is disconnected or changed, by monitoring the working state of the acceleration sensor of the mobile device, if the mobile device is detected to be moving away from the anti-lost device quickly, it may indicate that the mobile device has been stolen. The mobile device can issue a control signal similar to the above to cause the mobile device to directly enter the security mode that is provided by the system or preset by the user, or simultaneously send an alarm signal to the anti-lost device to remind the user.

Optionally, the additional determining rule further includes: after the wireless connection state of the anti-lost device and the mobile device is detached or changed, the mobile device can monitor, for example, what is the specific operation mode of the mobile device, for example, The operation of the mobile device is heavy for entering the system option immediately. To modify the data, or to attempt to shut down. If the above operation occurs, it may be determined that the mobile device has been stolen. At this time, the mobile device may issue a control signal similar to the above, so that the mobile device directly enters the security mode preset by the system or preset by the user, or simultaneously sends the anti-lost device to the anti-lost device. An alarm signal to alert the user.

Alternatively, the anti-lost device according to the present invention can also implement the function of retrieving the lost mobile device by transmitting a control signal. For example, when it is determined that the mobile device is stolen by the wireless communication status between the communication module of the mobile device and the wireless module of the anti-lost device, the anti-lost device may send a control signal to the mobile device to activate the positioning function of the mobile device, for example, The GPS module of the mobile device locates the current location of the mobile device, and then can send the location information to the cloud server through the wireless network of the mobile device, or to the cloud server, other synchronized terminals (such as the user). A personal computer or other mobile device) or sent back to the anti-lost device for storage or forwarding. With this location information, users can easily track and retrieve lost mobile devices, or use this information to help locate thieves to protect mobile devices.

According to the present invention, the mobile device can also perform two-way interaction with the anti-lost device to implement a two-way search function. For example, when the user can't find the mobile device or the anti-lost device, just operate the software on the mobile device (such as app) or press a specific button on the anti-lost device, the other party will make a sound prompt to help Users quickly locate mobile devices or anti-lost devices.

According to the present invention, when the anti-lost device and the mobile device are located within a certain distance range, since the anti-lost device has provided reliable security for the mobile device, the mobile device can be automatically decrypted, that is, the user does not need to open the mobile device every time.
