Detailed ways

In practical applications, the user equipment is usually used in field rescue, and it may not be convenient to perform a charging operation. For example, the user equipment is used at sea or deep in a mountain. Therefore, the battery life of the user equipment is particularly important. However, in the prior art, limited by the obstacles of battery technology, the energy density of the battery is relatively low. At the same time, for the convenience of portability, the user equipment is developing towards miniaturization and miniaturization, which leads to an increasingly narrow space for installing batteries inside the user equipment, which in turn leads to poor battery life of the user equipment.

In the embodiment of the present invention, the user equipment is not always in the working state, but enters the dormant state if no control signal input by the user is detected when the working state is maintained for a period of time corresponding to the current working mode. , so that the power consumption of the user equipment can be reduced, so the battery life of the user equipment can be improved.

In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

An embodiment of the present invention provides a method for improving battery life of a user equipment. Referring to FIG. 1 , specific steps will be described in detail below.

Step S101, when it is in the working state, acquire the geographic location information of the user equipment itself.

In a specific implementation, a positioning chip may be built in the user equipment. When the user equipment is in the working state, the positioning chip can be used to perform a positioning operation, so that the geographic location information of the location of the user equipment itself can be obtained. The geographic location information of the user equipment itself may include longitude information and latitude information of the location of the user equipment.

After the user equipment obtains its own geographical location information through the positioning chip, it can process the geographical location information, generate a radio frequency signal, and send its own geographical location information to the rescue base station through the antenna. After receiving the signal sent by the user equipment, the rescue base station obtains the geographic location information of the user equipment, and can know the current location of the user equipment, so that a rescue team can be quickly dispatched for rescue.

In the embodiment of the present invention, a main controller may be provided in the user equipment, and the main controller is connected to the positioning chip through a data interface. After positioning, the positioning chip can transmit the obtained positioning information, that is, the geographical position information of the user equipment itself, to the main controller through the data interface. The main controller can encapsulate the geographic location information of the user equipment itself into a call short message, and after performing a series of modulation, frequency conversion, filtering, and amplification on the call short message, send the call short message through the antenna.

The built-in positioning chip in the user equipment can be a Global Positioning System (Global Positioning System, GPS) chip, a Bei Dou Navigation Satellite System (Bei Dou Navigation Satellite System) chip, or other types of satellite positioning system chips, as long as the positioning can be realized function.

In recent years, my country's Beidou satellite navigation system has continued to mature and has developed into one of the world's four major satellite positioning systems. The current open Beidou satellite navigation system has an uplink low frequency band of 1610-1626.5MHz and a downlink high frequency band of 2483.5-2500MHz. Compared with the GPS system currently occupying a dominant position in the market, the Beidou system has dual functions of positioning and communication, while the GPS system only has the positioning function and does not have the communication function.

Beidou satellite's unique two-way communication function and precise positioning system have laid a solid foundation for my country's emergency search and rescue. It has the characteristics of small number of satellites, small investment, simple user equipment, low price, and low operating communication costs. Beidou satellite navigation system has powerful functions in communication and positioning, mainly including: Beidou satellite navigation system has positioning and communication functions at the same time, without the support of other communication systems; Beidou satellite navigation system covers China and surrounding countries and regions, 24 hours a day, There is no communication blind zone and basically no time delay; Beidou satellite navigation system is especially suitable for large-scale monitoring and management of group users, as well as data transmission applications for data collection users in unsupported areas; Beidou satellite navigation system's unique central node positioning processing and commanding users The machine design can solve the requirements of two-way positioning at the same time.

In an embodiment of the present invention, the user equipment is a Beidou terminal device supporting the Beidou satellite navigation system, and adopts a Beidou satellite navigation system chip for positioning. Since the Beidou satellite navigation system supports both positioning and communication functions, Beidou terminal equipment can independently complete positioning and communicate with rescue base stations.

In another embodiment of the present invention, the user equipment is a terminal equipment supporting GPS positioning. Since GPS only supports the positioning function, the terminal equipment using GPS positioning needs to communicate with the rescue base station by means of other communication methods, for example, communicate with the rescue base station through 4G, 3G and other mobile communication networks. However, when the signal of the mobile communication network is poor, the terminal device using GPS positioning may not be able to send its own geographical location information to the rescue base station in time.

Compared with the terminal equipment using GPS positioning, because the Beidou terminal equipment itself has the communication function, it can directly communicate with the Beidou satellite without communicating through the mobile communication network, so it can send its own geographical location information through the Beidou satellite in a timely manner. to the rescue base station to ensure that the user can be searched by rescuers in time.

Step S102, when the duration of maintaining the working state is longer than the working duration corresponding to the current working mode, and no manipulation signal from the user is detected, control the user equipment to enter the sleep state.

In a specific implementation, the working mode corresponding to the user equipment may be preset. The working mode of the user equipment may be one, or two or more. For each working mode, the corresponding working hours can be preset. The working duration of the user equipment in each working mode is: in this working mode, the duration of the user equipment working once.

For example, there are two preset working modes corresponding to the user equipment, one is a default working mode, and the other is a continuous working mode. The corresponding working time in the default working mode is 5 minutes, that is, the duration of each work of the user equipment is 5 minutes. The corresponding working duration in the continuous working mode is 2 minutes, that is, the duration of each working of the user equipment is 2 minutes.

After the user equipment enters the working state, it can first know the current working mode. The user equipment can start counting after entering the working state, and when the counting time reaches the working time corresponding to the current working mode, if the user equipment does not detect the user's manipulation signal, it can enter the sleep state.

For example, the user equipment is currently in a default working mode. The user equipment starts counting when it enters the working state. When the counting time reaches 5 minutes and no manipulation signal from the user is detected, the user equipment switches from the working state to the dormant state.

In a specific implementation, when the timing duration reaches the working duration corresponding to the current working mode, the following scenario may also exist: the user equipment currently detects the user's manipulation signal, that is, the user is currently manipulating the user equipment. At this time, if the user equipment is directly switched from the working state to the sleeping state, the current control of the user will become invalid. For example, if the user is currently editing distress information, if the user equipment switches directly from the working state to the dormant state, the user can only send the distress information currently being edited after the user equipment enters the working state next time, resulting in poor transmission of life-saving information. timely.

Therefore, in order to avoid the occurrence of the above situation, when the timed duration reaches the working duration corresponding to the current working mode, if the user equipment detects the user's manipulation signal, the user equipment can continue to maintain the working state. However, if the user equipment is always in the working state, the power consumption of the user equipment will be high. In order to reduce the power consumption of the user equipment, the time length from the last detection of the user's manipulation signal may be obtained in real time. When the time since the last detection of the user's manipulation signal is longer than the working time corresponding to the current working mode, the user equipment switches from the working state to the sleeping state.

For example, the user equipment is currently in the default working mode, and the current time is 5 minutes away from the last detection of the user's manipulation signal, then the user equipment can be switched from the working state to the sleeping state at this time.

In a specific implementation, when the user equipment enters the dormant state, if no manipulation signal from the user is detected during the dormant period, the user equipment may be woken up at regular intervals and switched from the dormant state to the working state.

In the embodiment of the present invention, after the user equipment enters the dormant state, the user equipment may be woken up periodically according to the current working mode of the user equipment. A wake-up period corresponding to each working mode of the user equipment may be preset. When no manipulation command input by the user is detected, the user equipment is periodically woken up once every other wake-up cycle, and enters the working state.

For example, when the user equipment is in the default working mode, the corresponding wake-up period is 4 hours, and the corresponding working time is 5 minutes. Then, after working for 5 minutes, the user equipment enters the dormant state from the working state if no manipulation signal of the user is detected. During the dormancy period, if no manipulation signal from the user is detected, the user equipment re-enters the working state after entering the dormant state for 4 hours, and re-executes step S101.

In a specific implementation, when the user equipment enters the dormant state, the user may manipulate the user equipment. At this time, if the user equipment detects the user's manipulation signal, the user equipment may switch from the dormant state to the working state. After switching to the working state, the user equipment can obtain the time length from the last detection of the user's manipulation signal in real time, and when the time length from the last detection of the user's manipulation signal is greater than the working time corresponding to the current working mode, re-enter dormant state.

In a specific implementation, the working mode of the user equipment is not always fixed, and the user equipment can actively switch its own working mode according to certain conditions. In the embodiment of the present invention, the time interval between the current time and the latest power-on time of the user equipment may be obtained to determine whether to switch the working mode. When the time interval between the current moment and the latest power-on time of the user equipment is less than the first time value, control the user equipment to be in the first working mode, and regularly wake up the user equipment with the first duration; When the time interval is greater than the first time value, control the user equipment to be in the second working mode, and wake up the user equipment regularly with the second duration, wherein: the first duration is the wake-up cycle corresponding to the first working mode, and the second duration is the second working mode The wake-up period corresponding to the mode, and the first duration is shorter than the second duration.

In a specific implementation, the first time value may be set according to an actual application scenario. In an embodiment of the present invention, the first time value is set to 24 hours, that is, within 24 hours after the current power-on of the user equipment, the user equipment is in the first working mode; within 24 hours after the current power-on of the user equipment After hours, the user equipment is in the second working mode.

For example, the first time value is 24 hours, the first working mode is the default working mode, the corresponding wake-up period is 4 hours, and the working time after waking up is 5 minutes; the second working mode is the low-power working mode, and the corresponding wake-up period is 5 minutes. The cycle time is 8 hours, and the working time after waking up is 5 minutes. If the user equipment is turned off at 0:15 on July 1, 2016, then from 0:15 on July 1, 2016 to 0:15 on July 2, 2016, the user equipment will work in the default mode. After working for 5 minutes, it enters the sleep state, wakes up every 4 hours, and switches from the sleep state to the working state. After 0:15 on July 2, 2016, the user equipment works in a low-power mode, enters a sleep state every 5 minutes, wakes up every 8 hours, and switches from a sleep state to a working state.

In a specific implementation, the user may also actively switch the working mode of the user equipment. On the operation interface of the user equipment, the current working mode of the user equipment and the selectable working modes of the user equipment may be displayed. The user can select the working mode of the user equipment by pressing a key. When the user equipment detects that the working mode selected by the user is different from the current working mode of the user equipment, it is determined that the user has input a working mode switching instruction. At this time, the user equipment may switch from the current working mode to the target working mode corresponding to the working mode switching instruction.

For example, the working modes of the user equipment include the default working mode and the low-power working mode, wherein, the sleep time of the default working mode is 4 hours, and the working time is 5 minutes; the sleeping time of the low-power working mode is 8 hours, and the working time is 5 minutes. 5 minutes, the user device is currently in the default working mode. The user finds on the display screen of the user equipment that the battery power of the user equipment is 30%, and the user thinks that the battery power of the user equipment is low, so the user can select a low power consumption mode on the operation interface of the user equipment, thereby turning the user equipment Switch from default operating mode to low power operating mode. After the user equipment is switched from the default working mode to the low power consumption mode, the power consumption can be greatly reduced, that is, the battery life of the user equipment is improved.

It can be understood that the user equipment may also have other working modes, for example, the working modes of the user equipment may also include a continuous working mode. When the user equipment is in the continuous working mode, it can frequently and continuously communicate with the rescue base station. When the user equipment is in the continuous working mode, the working time of the user equipment is 1 minute, and the wake-up period is 5 minutes. At this time, the power consumption of the user equipment is relatively high.

In a specific implementation, a display screen may be set in the user equipment for outputting a display interface. When the user equipment is in the dormant state, the display screen of the user equipment can be controlled to enter the standby state, and the positioning chip in the user equipment can be controlled to stop working. In practical applications, entering the standby state of the display screen may be entering a black screen state.

It can be understood that in practical applications, when the user equipment is in a dormant state, it is also possible to control some power-consuming components in the user equipment to stop working, and it is only necessary to ensure that the user equipment can be woken up in time when a user's manipulation command is detected. . For example, when the user equipment is in a dormant state, in the user equipment, the battery only supplies power to the main controller and buttons, and other working modules are powered off.

Compared with the user equipment in the working state, the power consumption of the user equipment in the dormant state is much lower than that in the working state. In view of the particularity of the user equipment application scenarios, the user equipment does not need to maintain communication with the rescue base station in real time. It can only communicate with the rescue base station when needed, or send its own geographic location information to the rescue base station at regular intervals. In the dormant state, the power consumption of the user equipment can be reduced, and the battery life of the user equipment can be improved.
