FIG. 1 is a schematic work flow diagram of the present invention
FIG. 2 is a more detailed workflow diagram of the present invention
FIG. 3 is a schematic structural diagram of an embodiment of the present invention
FIG. 4 is a schematic structural diagram of another embodiment of the present invention
FIG. 5 is a schematic structural diagram of yet another embodiment of the present invention
The specific implementation mode is as follows:
the invention adopts the technical scheme that the anti-long-distance alarm is divided into two parts: a target end and a carrying end. The target end and the carrying end are respectively provided with a wireless module, whether the wireless signals at the two ends can be sent or not is judged, when the target end and the carrying end are confirmed to be away, countdown is started by taking the stored fixed time length as the starting time length, and when the countdown is finished, an alarm signal is sent.
As shown in fig. 1, in a normal state, the target end and the carrying end are adjacent to each other and are in a close distance, and when the target end and the carrying end are far away from each other to a certain distance and cannot communicate with each other, the target end and the carrying end are considered to be in a leaving state, a countdown is started, and when the countdown is finished, an alarm is started.
The specific implementation will consider more details, so the workflow will be more complex, and for the convenience of understanding and implementation of those skilled in the art, the workflow will be further explained with reference to the workflow diagram of fig. 2 which is slightly detailed: in implementation, both the carrying end and the target end can have an alarm function, and the end with the alarm function is called the alarm end. When the target end and the carrying end are in a non-separated state, the alarm end checks whether the other end is separated at a small interval time, if not, the alarm end does not act, and if so, the alarm end counts down at a set countdown starting time. The countdown period also checks at a small interval to see if the other end is back to the vicinity, and if the other end is back to the vicinity, the state is restored to the not-left state, and if the other end is not back to the vicinity until the countdown is finished, an alarm is started. And in the process of alarming, whether the other end returns to the vicinity is checked at a small interval, if so, the alarming is stopped and the state is recovered to the non-leaving state, otherwise, the alarming is continued until the user turns off or delays the alarming of the local end through a key on the alarming end.
The specific implementation of the carrying end and the target end is as follows:
carrying end: the portable terminal-essential module includes: the portable terminal wireless module, the portable terminal control processing unit, the portable terminal battery, the portable terminal closing and delay alarm key group, the display screen and the portable terminal alarm device can be selectively added with other functional modules according to different implementation modes, such as a countdown setting key group and the like.
