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.
Example one
Referring to fig. 1, which is a schematic flow chart of a power control method of a wearable device according to an embodiment of the present invention, the wearable device control method according to the embodiment of the present invention includes steps S101 to S104.

It should be noted that the wearable device may be an intelligent device having a motion sensing function and a positioning function, such as an intelligent bracelet or an intelligent watch. For realizing this wearable device's locate function, be equipped with communication module, WIFI module and GPS module in this embodiment. In order to realize GPS positioning, a GPS module is used in this embodiment; in order to realize LBS location, a communication module is adopted in the embodiment; in order to realize WIFI positioning, a WIFI module is adopted in this embodiment. Specifically, a GPS positioning mode, an LBS positioning mode and a WIFI mode are adopted for positioning, positioning information is stored in a database, and an electronic fence is constructed according to the positioning information collected in a preset time period. Wherein the preset time period may be a period required for constructing the electronic fence. Illustratively, for the construction of the electronic fence, a user wears the wearable device within a preset time period, and then the wearable device periodically and simultaneously adopts a GPS positioning mode, an LBS positioning mode and a WIFI mode to perform positioning, so as to obtain positioning information under three positioning conditions, simultaneously associate the LBS base station positioning information and all WIFI addresses under the position, store the three positioning information into a database, and mark the GPS positioning information as the position information of the current position point in a digital map.
Further, the position information of the user in the preset time period and the related LBS base station positioning information and WIFI address are continuously marked and supplemented in the data map by adopting the mode. Furthermore, all the marked points are periodically combined into a plane area graph in the map, and the preset distance is extended according to the edge points in the upper direction, the lower direction, the left direction and the right direction to be used as the edge of the plane area graph. Further, the high-frequency location point may be a location point that must appear for a user many times or every day, such as a user's residence, work place, etc., and the high-frequency location point information may be positioning information of the user's residence, work place, etc. The abnormal position point is a position point which appears for a preset number of times in the preset time period. For example, a position point or an area where a user appears only once in a week period is used as an abnormal position point, and positioning information corresponding to the abnormal position point is recorded. Specifically, the high-frequency position point is taken as a reference point, all planar area graphs drawn in the preset time period are covered, and the abnormal position point is removed, so that the construction of the electronic fence is completed.

In this embodiment, the change of the human body action is detected by an acceleration sensor configured in the wearable device, so as to determine whether the wearable device is in a moving state, where the acceleration sensor may be a device with a motion sensing function, such as a pedometer or a gyroscope. For example, the wearable device is worn by the user, the wearable device is provided with a pedometer, and the current movement state of the wearable device, namely the current motion state of the user, can be judged according to the data detected by the pedometer.
In an alternative embodiment, the method comprises the following steps of:

and if the GPS positioning information corresponding to the currently acquired LBS base station positioning information and WIFI address does not exist in the database, the wearable equipment is considered to be in an abnormal monitoring state.
It should be noted that, based on the completion of the database and the electronic fence, the wearable device turns off the GPS positioning mode with higher power consumption, and only turns on the LBS positioning mode and the WIFI mode, where the working mode of the wearable device is the low power consumption mode. Therefore, positioning information is obtained according to the LBS positioning mode and the WIFI mode, and whether the GPS positioning information corresponding to the currently acquired LBS base station positioning information and the WIFI address exists in the database or not is detected, so that the supervision state of the wearable device is judged. In this embodiment, the normal monitoring state of the wearable device is a monitoring state under the condition that the wearable device searches for the GPS positioning information matched with the currently acquired LBS base station positioning information and WIFI address from the database. Similarly, the abnormal monitoring state of the wearable device is a monitoring state under the condition that the wearable device does not search the GPS positioning information matched with the currently acquired LBS base station positioning information and the WIFI address from the database.

Specifically, step S104 includes:
and when the wearable device is detected to be in a non-moving state within a preset time period, switching the working mode into the sleep mode, and taking the positioning result of the last positioning as the positioning result of the current positioning.
It should be noted that, in the normal state supervision, according to the change of the human body motion acquired by the acceleration sensor of the wearable device, the wearable device is considered to be in the non-moving state, and when the non-moving state lasts for a period of time, one-time positioning is completed, all positioning modules are turned off, that is, the working mode of the wearable device is converted from the low power consumption mode to the sleep mode, so that the power consumption of the device is further reduced. And when the positioning information is subsequently recorded, taking the last positioning result as the current positioning result.

It should be noted that, in this embodiment, the wearable device is configured with an alarm module to remind a wearing person, and the alarm module may be a device having an alarm function. Illustratively, when the to-be-located point is detected not to be located in the electronic fence, the wearable device keeps an open mode, alarm information is generated and sent to an alarm module and a management platform, so that a buzzer and a vibration module in the alarm module remind a person wearing the wearable device, and the management platform performs emergency processing according to the received alarm information.
