Description
Technical Field

With the rapid attack of the internet of things era, many mobile internet of things terminal devices without external fixed power supply have severe requirements on power supply problems, and various cost increases caused by frequent battery replacement also have new requirements on battery capacity and service life. For example: a typical operation time of a narrowband internet of things (NB-IoT) terminal device is not shorter than 10 years.
In the face of the new requirements, the prior art often selects a battery with low self-discharge rate and large capacity to supply power. Meanwhile, the prior art will also reduce the power consumption of the terminal as much as possible, for example: a more advanced production process is adopted to reduce the power supply voltage as much as possible; a Power Saving Mode (PSM) is adopted, so that the terminal can enter a deep sleep state and only a few active circuits such as clocks are available; the extended discontinuous reception (eDRX) is adopted so that the terminal can further reduce the terminal connected state and standby power consumption by extending the DRX cycle.

The self-discharge rate and the discharge characteristic of the battery are greatly influenced by temperature, and if the battery is in a high-temperature state for a long time, the self-discharge rate of the battery is obviously increased, so that the service life of the battery is seriously influenced; meanwhile, if the battery is in a low-temperature environment lower than-20 ℃, the battery with insufficient electric quantity is more likely to have the situation of being incapable of normally supplying power. In addition, unexpected faults such as electric leakage or short circuit of the terminal equipment are also often represented as shutdown caused by insufficient battery power or exhausted battery power; in addition, due to the electrochemical characteristics of the primary lithium battery frequently used by the mobile internet of things terminal, the time from the alarm voltage with insufficient electric quantity to the shutdown voltage with seriously insufficient electric quantity is very short; in addition, the particularity of the service environment of the mobile internet of things terminal is that it is often difficult to replace the battery in time in a short time (1-2 hours), for example: the method is applied to mobile Internet of things terminal equipment for logistics tracking.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic diagram of a terminal hardware structure according to a technical solution of an embodiment of the present invention; as shown in fig. 1, the narrow-band internet of things terminal according to the embodiment of the present invention includes two batteries, namely a battery a and a battery B; the battery A is fixed in the battery groove A; the battery B is fixed in the battery groove B; the narrow-band Internet of things terminal further comprises a control module, and the control module is used for controlling the battery A or the battery B to be in a working state.
The battery a may be a main battery used by the narrow-band internet of things terminal during normal operation, and correspondingly, the battery B may be a backup battery. It can be understood that the emergency use of battery B as a backup battery is switched to when the electric quantity of battery a is too low or other abnormal conditions occur. Based on this, the battery B and the battery a may have the same operating parameters, such as operating voltage, operating current, and the like; the battery capacities of the battery B and the battery A can be the same or different. As one of the embodiments, in order to reduce the volume to realize the advantage of low cost, the battery capacity of the battery B as the backup battery may be smaller than the battery a, for example, the capacity of the battery B is 10% or less of the capacity of the battery a, thereby enabling the realization of small volume and the reduction of cost. In order to further reduce the cost of battery B, the operating voltage of battery B may even be slightly lower than the operating voltage of battery a, but the operating voltage of battery B still needs to be higher than the cut-off voltage of the terminal. As one of the embodiments, for example: the cut-off voltage of the narrow-band internet of things terminal is 2.1V, the working voltage of the battery A is 3.6V, and the working voltage of the battery B can be 3V.
The above example of fig. 1 is only a schematic diagram of a hardware entity implementing the embodiment of the present invention, and the embodiment of the present invention is not limited to the above hardware entity structure of fig. 1; based on the hardware entity structure, various embodiments of the present invention are presented.
In the following embodiments, the battery a may be referred to as a first power supply unit, and the battery B may be referred to as a second power supply unit.
Example one
The embodiment of the invention provides an information processing method which is applied to a narrow-band Internet of things terminal. FIG. 2 is a flowchart illustrating an information processing method according to a first embodiment of the present invention; as shown in fig. 2, the method includes:
step 201: the terminal monitors characteristic parameters of a first power supply unit in a working state; the characteristic parameter comprises electric quantity; and when the electric quantity of the first power supply unit is lower than a preset threshold value, generating an electric quantity alarm instruction.
Step 202: and the terminal sends an electric quantity abnormal report to the base station based on the electric quantity alarm instruction and switches the second power supply unit to be in a working state.
Step 203: and the terminal receives a confirmation message which is sent by the base station and corresponds to the electric quantity abnormal report so as to determine that the base station sends the electric quantity abnormal report to the maintenance terminal through a core network.
In this embodiment, the narrowband internet of things (NB-IoT) terminal may be a mobile terminal. In the hardware entity structure shown in fig. 1, the narrowband internet of things terminal includes a first power supply unit and a second power supply unit, and in a normal state, the narrowband internet of things terminal uses the first power supply unit to supply power, that is, in a normal state, the first power supply unit is in a working state. Based on this, in step 201, the narrowband internet of things terminal monitors the characteristic parameters of the first power supply unit, specifically monitors the electric quantity of the first power supply unit; when the electric quantity of the first power supply unit is lower than a preset threshold value, an electric quantity alarm instruction is generated, an electric quantity abnormal report is sent to the base station based on the electric quantity alarm instruction, and then the base station sends the electric quantity abnormal report to the maintenance terminal through the core network so as to inform maintenance personnel that the first power supply unit is in an abnormal state, so that the maintenance personnel can replace the first power supply unit in time. The maintenance terminal can be a terminal used by maintenance personnel; the maintenance terminal can also be an application server. In the following embodiments of the present invention, the terminals all refer to narrowband internet of things (NB-IoT) terminals.
On the other hand, in this embodiment, when it is monitored that the electric quantity of the first power supply unit is lower than the preset threshold, an electric quantity alarm instruction is generated, the second power supply unit is switched to be in a working state based on the electric quantity alarm instruction, and the standby power supply is switched to work in time, so that shutdown of the terminal caused by insufficient electric quantity of the first power supply unit is avoided, and reliability of uninterrupted use of the terminal is ensured.
In addition, for terminals, especially NB-IoT terminals, there are generally four modes of operation: a receive state, a transmit state, an idle state, and a sleep state. While NB-IoT terminals may be dormant for the most part of the time. This makes the terminal have a low probability of sending a power abnormality report, which may not be sent until months or years. Once the terminal sends an electric quantity abnormal report, the terminal is immediately switched into a receiving state/sending state working mode no matter the terminal is in a dormant state or an idle state, and the electric quantity abnormal report is sent to the base station based on the receiving state/sending state working mode.
In this embodiment, the sending, by the terminal, the power abnormality report to the base station may include two implementation manners, as a first implementation manner, that is, a manner of not retransmitting, where the sending the power abnormality report to the base station includes: after the terminal completes the synchronization process with the base station, system information is obtained;
based on the resource allocation condition of the system information, the terminal sends a random access request to a base station through a random access channel; the random access request indicates the terminal to send an abnormal report;
and the terminal receives the downlink control information and sends an electric quantity abnormal report to the base station based on the resource allocated for the uplink in the downlink control information.
Based on the foregoing embodiment, further, when the power quantity abnormality report is not successfully transmitted to the base station, the method further includes: the terminal receives downlink control information which is sent by the base station and represents a negative response;
and retransmitting the power quantity abnormal report to the base station based on the retransmission resource allocated for the uplink in the downlink control information.
The exception report in this embodiment may be specifically an electricity quantity exception report.
In this embodiment, the random access request indicates that an exception report to be sent is at a high priority.
The two embodiments are described in detail below with reference to specific application scenarios.
Application scenario one
Fig. 3 is a schematic flowchart of a first application scenario of an information processing method according to a first embodiment of the present invention; as shown in fig. 3, in the application scenario, the terminal is specifically a mobile terminal, and is represented by User Equipment (UE) in the figure; the information processing method comprises the following steps:
step 301: and the terminal and a Base Station (BS) are synchronized to complete the synchronization process.
Step 302: the terminal acquires system information SI. The system message may specifically be basic system information (PSI).
Step 303: the terminal sends a Random Access Request (Random Access Request) through a Random Access channel based on the resource allocation condition of the system information; indicating that the terminal is about to send an abnormal report in the random access request; the exception is reported as high priority. The exception report in this embodiment may be specifically an electricity quantity exception report. The random access Request may specifically be a radio resource control access Request (RRC Connection Request) message. The Random access channel may be a Physical Random Access Channel (PRACH)
Step 304: a terminal receives Downlink Control Information (DCI); the Downlink control information defines Downlink resource Allocation (Downlink Allocation) for a Random Access Response (Random Access Response) and also defines uplink resource Allocation (uplink Allocation) for an exception report.
Step 305: the terminal receives a Random Access Response (Random Access Response) message of the base station.
Step 306: and the terminal sends an electric quantity abnormal report in the uplink resource allocated by the uplink resource.
Step 307: and the base station transmits the power abnormality report to a core network (SGSN).
Step 308: and the base station sends the confirmation response information to the terminal.
So far, under the application scene, the terminal reports the electric quantity abnormal report to be completed.
Application scenario two
Fig. 4 is a schematic flowchart of a second application scenario of the information processing method according to the first embodiment of the present invention; as shown in fig. 4, the information processing method includes:
step 401: and the terminal and a Base Station (BS) are synchronized to complete the synchronization process.
Step 402: the terminal acquires system information SI. The system message may specifically be basic system information (PSI).
Step 403: the terminal sends a Random Access Request (Random Access Request) through a Random Access channel based on the resource allocation condition of the system information; indicating that the terminal is about to send an abnormal report in the random access request; the exception is reported as high priority. The exception report in this embodiment may be specifically an electricity quantity exception report. The random access Request may specifically be a radio resource control access Request (RRC Connection Request) message. The random access channel may specifically be a Physical Random Access Channel (PRACH)
Step 404: a terminal receives Downlink Control Information (DCI); the Downlink control information defines Downlink resource Allocation (Downlink Allocation) for a Random Access Response (Random Access Response) and also defines uplink resource Allocation (uplink Allocation) for an exception report.
Step 405: the terminal receives a Random Access Response (Random Access Response) message of the base station.
Step 406: and the terminal sends an electric quantity abnormal report in the uplink resource allocated by the uplink resource.
Step 407: the terminal receives DCI carrying Negative Acknowledgement (NACK) returned to the terminal by the base station; the DCI defines an uplink retransmission resource allocation.
Step 408: and the terminal retransmits the power abnormality report based on the retransmission resource allocated for the uplink.
Step 409: and the base station transmits the power abnormality report to a core network (SGSN).
Step 410: and the base station sends the confirmation response information to the terminal. The base station may specifically send the acknowledgement response message through a Physical Downlink Control Channel (PDCCH).
So far, under the application scene, the terminal reports the electric quantity abnormal report to be completed.
The existing random access procedures can be divided into a random access procedure based on collision and a random access procedure based on non-collision. The difference is the way in which the random access prefix is selected for both flows. The former is that UE randomly selects a random prefix from random access prefixes based on conflict according to a certain algorithm; the latter is that the base station side assigns non-conflicting random access prefixes to the UE through downlink dedicated signaling.
Wherein, the random access process based on conflict comprises:
1) UE sends random access prefix on RACH;
2) a MAC layer of a base station (eNB) generates a random access response and transmits on a downlink shared channel (DL-SCH);
3) the RRC layer of the UE generates an RRC Connection Request (RRC Connection Request) and maps the RRC Connection Request to a Common Control Channel (CCCH) logical channel on an uplink shared channel (UL-SCH) for transmission;
4) the RRC context Resolution is generated by the RRC layer of the eNB and transmitted on the CCCH or dedicated control channel DCCH logical channel mapped on the DL-SCH.
In another aspect, a non-collision based random access procedure comprises:
1) a base station (eNB) assigns a non-colliding Random Access Preamble (non-contention Random Access Preamble) to a UE through downlink dedicated signaling, the prefix not being in a set of Broadcast Channel (BCH) broadcasts.
2) The UE transmits the assigned random access prefix on the RACH.
The MAC layer of the base station (eNB) generates a random access response and transmits on the DL-SCH.
In existing 4G networks, non-collision based random access is applicable to higher priority random access requests than collision based random access, such as: and the terminal switches the cell in the conversation process. However, the information similar to the exception report belongs to the category of the random access based on the conflict, and the priority of each random access request cannot be further distinguished in all the random access requests based on the conflict. As can be seen, in the existing 4G network, among a plurality of random access requests based on collisions, the report of abnormal power consumption is only treated as one piece of reported information, and is not granted with access permission of high priority. If channel resource conflict exists, the power abnormal report may not be sent preferentially, which results in that the real-time performance of the power abnormal report transmission cannot be guaranteed.
In the above description, the process of reporting the abnormal power report by the terminal may include: synchronization, PSI, PRACH, uplink Assignment, uplink data transfer, and uplink data acknowledgement (Ack for uplink data). In this embodiment, the power quantity exception report usually occupies 20 bytes, and the duration of the above procedure generally does not exceed 10 seconds. Fig. 5 is a schematic diagram illustrating a transmission process of a power abnormality report according to an embodiment of the present invention; as shown in FIG. 5, i.e. Tsync+TPSI+TPRACH+TUplinkAssignment+TUplinkData+TUplinkAckLess than or equal to 10 s. In addition, in this embodiment, the power quantity abnormality report is sent with high priority, which may be understood as that the power quantity abnormality report is sent preferentially when network congestion occurs and data, signaling and the power quantity abnormality report need to be sent simultaneously.
By adopting the technical scheme of the embodiment of the invention, when the electric quantity of the main power supply unit (the first power supply unit) is too low, on one hand, the uninterrupted use of the mobile Internet of things terminal is realized by switching the standby power supply unit (the second power supply unit) to be in a working state; on the other hand, the terminal sends an electric quantity abnormal report to the base station so as to inform maintenance personnel to repair/replace the main power supply unit in time, and the reliability of uninterrupted use of the mobile Internet of things terminal is also ensured.
Example two
The embodiment of the invention also provides an information processing method. FIG. 6 is a flowchart illustrating an information processing method according to a second embodiment of the present invention; as shown in fig. 6, in this embodiment, based on the description of the first embodiment, the method further includes:
step 601: the terminal monitors characteristic parameters of a first power supply unit in a working state; the characteristic parameter includes an electric quantity.
Step 602: and when the electric quantity of the first power supply unit is not lower than a preset threshold value, the terminal detects the working mode of the terminal.
Step 603: and controlling the first power supply unit or the second power supply unit to be in a working state based on the detection result.
The application scenarios of the information processing method of the embodiment are as follows: for terminals, especially NB-IoT terminals, there are generally four modes of operation: a receive state, a transmit state, an idle state, and a sleep state. When the terminal is in a sending state, the overall voltage/current requirement of the terminal is the highest; when the terminal is in the sleep state, the overall voltage/current requirements of the terminal are minimal. Since the larger the voltage difference to be converted (the difference between the two voltage values before and after conversion), the lower the conversion efficiency, and the larger the power consumption required for the voltage conversion. Therefore, if the voltage difference to be converted can be reduced as much as possible, the power consumption of the terminal can be effectively reduced. Based on this, the information processing method of the present embodiment is proposed.
In this embodiment, the characteristic parameter further includes a voltage; in step 603, the controlling the first power supply unit or the second power supply unit to be in the working state based on the detection result includes: when the terminal detects that the terminal is in a first working mode, obtaining a maximum voltage value corresponding to the first working mode;
and selecting the power supply unit with the minimum difference value with the maximum voltage value based on the first voltage value of the first power supply unit and the second voltage value of the second power supply unit, and controlling the power supply unit to be in a working state.
Specifically, as an example, the nominal voltage (or rated voltage) of the first power supply unit of the terminal is Va, and the nominal voltage (or rated voltage) of the second power supply unit is Vb; if the terminal is currently in a certain working mode, the maximum voltage required when the terminal is in the working mode is V1; if | V1-Va | ≦ | V1-Vb |, it indicates that the difference between the first voltage value of the first power supply unit and the maximum voltage value V1 is minimum, and when the first power supply unit is in the working state as a main power supply unit, the terminal still controls the first power supply unit to be in the working state. As another example, the nominal voltage (or rated voltage) of the first power supply unit of the terminal is Va, and the nominal voltage (or rated voltage) of the second power supply unit is Vb; if the terminal is currently in another working mode, the maximum voltage required when the terminal is in the other working mode is V2; if the | V2-Va | ≧ V2-Vb |, which indicates that the difference between the second voltage value of the second power supply unit and the maximum voltage value V2 is minimum, the terminal generates a switching instruction, and executes the second switching instruction to control the second power supply unit to be in the working state. This can significantly reduce the voltage difference to be converted, thereby effectively reducing the power consumption of the terminal.
The present embodiment will be described in detail with reference to specific application scenarios.
Application scenario three
For narrowband internet of things (NB-IoT) terminals, there are generally four modes of operation: the terminal comprises a receiving state, a sending state, an idle state and a dormant state, wherein when the terminal is in the sending state, the overall voltage/current requirement of the terminal is the highest; when the terminal is in the sleep state, the overall voltage/current requirements of the terminal are minimal. For example: for a certain terminal device, when the terminal is in a full power transmission state, the power supply voltage of the terminal needs to reach 4.7V; when the terminal is in a dormant state, the highest working voltage of the terminal only needs to reach 2.5V. And the voltages output by the first power supply unit and the second power supply unit are respectively constant at 3.6V and 3V. In order to reduce the conversion voltage difference as much as possible, when the terminal is in a sending state, the first power supply unit of 3.6V is controlled to be connected for supplying power; and when the terminal is in a dormant state, controlling the 3V second power supply unit to be connected for supplying power. This can significantly reduce the voltage difference to be converted, thereby effectively reducing the power consumption of the terminal.
By adopting the technical scheme of the embodiment of the invention, the power supply unit which is adapted to the different switching based on the working states of the terminal is in the working state, and the switching voltage difference can be greatly reduced when the working modes of the terminal are switched, so that the switching power consumption of the terminal is effectively reduced, and the service life of the power supply unit is prolonged.
EXAMPLE III
The embodiment of the invention also provides a terminal; the terminal is a narrow-band Internet of things terminal. Fig. 7 is a schematic structural diagram of a terminal according to an embodiment of the present invention; as shown in fig. 7, the terminal includes: a first power supply unit 51, a second power supply unit 52, a characteristic parameter monitoring unit 53, an alarm unit 54, a communication unit 55 and a control unit 56; wherein the content of the first and second substances,
the characteristic parameter monitoring unit 53 is configured to monitor a characteristic parameter of the first power supply unit 51 in an operating state; the characteristic parameter comprises electric quantity;
the alarm unit 54 is configured to generate an electric quantity alarm instruction when the electric quantity monitoring unit 53 monitors that the electric quantity of the first power supply unit 51 in the working state is lower than a preset threshold;
the communication unit 55 is configured to send an electric quantity exception report to a base station based on the electric quantity alarm instruction;
the control unit 56 is configured to switch the second power supply unit 52 to be in the working state when the electric quantity monitoring unit 53 monitors that the electric quantity of the first power supply unit 51 in the working state is lower than a preset threshold;
the communication unit 55 is further configured to receive a confirmation message corresponding to the power abnormal report and sent by the base station, so as to determine that the base station sends the power abnormal report to the maintenance terminal through the core network.
In this embodiment, the first power supply unit 51 (for example, the battery a) may be a main battery used by the terminal during normal operation, and correspondingly, the second power supply unit 52 (for example, the battery B) may be a backup battery. It can be understood that the emergency use of battery B as a backup battery is switched to when the electric quantity of battery a is too low or other abnormal conditions occur. Based on this, the battery B and the battery a may have the same operating parameters, such as operating voltage, operating current, and the like; the battery capacities of the battery B and the battery A can be the same or different. As one of the embodiments, in order to reduce the volume to realize the advantage of low cost, the battery capacity of the battery B as the backup battery may be smaller than the battery a, for example, the capacity of the battery B is 10% or less of the capacity of the battery a, thereby enabling the realization of small volume and the reduction of cost. In order to further reduce the cost of battery B, the operating voltage of battery B may even be slightly lower than the operating voltage of battery a, but the operating voltage of battery B still needs to be higher than the cut-off voltage of the terminal. As one of the embodiments, for example: the cutoff voltage of the terminal is 2.1V, the operating voltage of battery a is 3.6V, and the operating voltage of battery B may be 3V.
In this embodiment, when the characteristic parameter monitoring unit 53 monitors that the electric quantity of the first power supply unit 51 is lower than a preset threshold, the alarm unit 54 generates an electric quantity alarm instruction; on one hand, the control unit 56 switches the second power supply unit 52 to be in a working state, and switches the standby power supply to work in time, so that shutdown of the terminal caused by insufficient electric quantity of the first power supply unit 51 is avoided, and reliability of uninterrupted use of the terminal is ensured. On the other hand, after the alarm unit 54 generates the power alarm instruction, the communication unit 55 sends a power abnormal report to a network side (e.g., a base station), and the base station sends the power abnormal report to the maintenance terminal through the core network, so as to notify the maintenance personnel that the first power supply unit is in an abnormal state, which is convenient for the maintenance personnel to replace the first power supply unit in time. The maintenance terminal can be a terminal used by maintenance personnel; the maintenance terminal can also be an application server. . For terminals, especially NB-IoT terminals, there are generally four modes of operation: a receive state, a transmit state, an idle state, and a sleep state. While NB-IoT terminals may be dormant for the most part of the time. This makes the terminal have a low probability of sending a power abnormality report, which may not be sent until months or years. Once the terminal sends an electric quantity abnormal report, the terminal is immediately switched into a receiving state/sending state working mode no matter the terminal is in a dormant state or an idle state, and the electric quantity abnormal report is sent to the base station based on the receiving state/sending state working mode.
In this embodiment, the communication unit 55 sends the power abnormality report to the base station includes two embodiments. In an embodiment, the communication unit 55 is configured to obtain system information after completing a synchronization process with a base station; based on the resource allocation condition of the system information, sending a random access request to a base station through a random access channel; the random access request indicates the terminal to send an abnormal report; and receiving downlink control information, and sending an electric quantity abnormal report to a base station based on the resource allocated for the uplink in the downlink control information.
As another embodiment, the communication unit 55 is further configured to receive, when the power quantity abnormality report is not successfully sent to a base station, downlink control information indicating a negative acknowledgement sent by the base station; and retransmitting the power quantity abnormal report to the base station based on the retransmission resource allocated for the uplink in the downlink control information.
The exception report in this embodiment may be specifically an electricity quantity exception report.
In this embodiment, the random access request indicates that an exception report to be sent is in a high priority.
For the two sending manners, specific reference may be made to the specific description of the application scenario one and the application scenario two in the embodiment one, and details are not described here again.

The electric quantity monitoring unit is used for monitoring the electric quantity of the power supply unit in the working state. The alarm unit is used for generating an electric quantity alarm instruction when the electric quantity monitoring unit monitors that the electric quantity of the power supply unit in the working state is lower than a preset threshold value. And the communication unit is used for sending an electric quantity abnormity report to the base station based on the alarm instruction generated by the alarm unit.
Example four
The embodiment of the invention also provides the terminal. Fig. 9 is a schematic diagram of another structure of the terminal according to the embodiment of the present invention; as shown in fig. 9, the terminal includes: a first power supply unit 51, a second power supply unit 52, a characteristic parameter monitoring unit 53, a control unit 56, and an operation mode monitoring unit 57; wherein the content of the first and second substances,
the characteristic parameter monitoring unit 53 is configured to monitor a characteristic parameter of the first power supply unit 51 in an operating state; the characteristic parameter comprises electric quantity;
the working mode monitoring unit 57 is configured to monitor a working mode;
the control unit 56 is configured to control the first power supply unit 51 or the second power supply unit 52 to be in the operating state based on the monitoring result of the operating mode monitoring unit 57 when the characteristic parameter monitoring unit 53 monitors that the electric quantity of the first power supply unit 51 in the operating state is not lower than a preset threshold.
For terminals, especially NB-IoT terminals, there are generally four modes of operation: a receive state, a transmit state, an idle state, and a sleep state. When the terminal is in a sending state, the overall voltage/current requirement of the terminal is the highest; when the terminal is in the sleep state, the overall voltage/current requirements of the terminal are minimal. Since the larger the voltage difference to be converted (the difference between the two voltage values before and after conversion), the lower the conversion efficiency, and the larger the power consumption required for the voltage conversion. Therefore, if the voltage difference to be converted can be reduced as much as possible, the power consumption of the terminal can be effectively reduced. Based on this, the terminal of the present embodiment is proposed.
In this embodiment, the characteristic parameter further includes a voltage; the terminal further includes an application processing unit 58, configured to obtain a maximum voltage value corresponding to a first working mode when the terminal detects that the terminal is in the first working mode; and obtaining a first voltage value of the first power supply unit 51 and a second voltage value of the second power supply unit 52; selecting a power supply unit having a smallest difference from the maximum voltage value based on a first voltage value of the first power supply unit 51 and a second voltage value of the second power supply unit 52;
the control unit 56 is configured to control the power supply unit to be in a working state.
Specifically, as an example, the nominal voltage (or rated voltage) of the first power supply unit 51 of the terminal is Va, and the nominal voltage (or rated voltage) of the second power supply unit 52 is Vb; if the working mode monitoring unit 57 monitors that the current working mode is in a certain working mode, the maximum voltage required in the working mode is V1; if the application processing unit 58 determines that | V1-Va | ≦ V1-Vb |, indicating that the difference between the first voltage value of the first power supplying unit 51 and the maximum voltage value V1 is minimum, the controlling unit 56 still controls the first power supplying unit 51 to be in the working state when the first power supplying unit is in the working state as the main power supplying unit. As another example, the nominal voltage (or rated voltage) of the first power supply unit 51 of the terminal is Va, and the nominal voltage (or rated voltage) of the second power supply unit 52 is Vb; if the working mode monitoring unit 57 monitors that the current working mode is in another working mode, the maximum voltage required when the working mode is in the another working mode is V2; if the application processing unit 58 determines that | V2-Va | ≧ | V2-Vb |, which indicates that the difference between the second voltage value of the second power supply unit 52 and the maximum voltage value V2 is minimum, a switching instruction is generated, and the control unit 56 executes the switching instruction to control the second power supply unit 52 to be in the operating state. This can significantly reduce the voltage difference to be converted, thereby effectively reducing the power consumption of the terminal.

And the communication unit is used for sending an electric quantity abnormity report to the base station based on the alarm instruction generated by the alarm unit. On the other hand, the operation mode monitoring unit monitors the operation mode. The application processing unit determines the maximum voltage value required by the working mode based on the working mode monitored by the working mode monitoring unit; and determining the battery with the minimum difference value with the maximum voltage value based on the voltage value of the battery A and the voltage value of the battery B, and generating a switching instruction to enable the control unit to control the switch to be connected with the corresponding battery based on the switching instruction.
