DETAILED DESCRIPTION

[0030] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples consistent with some aspects of the present application as detailed in the attached claims.

[0031] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0032] The positioning function of the terminal device can be realized through the communication module used for positioning in the terminal device. Generally speaking, when the terminal device is turned off and not in a charging state, the communication module used for positioning in the terminal device has no power source. Therefore, the terminal device in the turned-off state does not have the positioning function. However, based on the user's needs for security and positioning traceability, the terminal device needs to have the positioning function even after it is turned off (hereinafter referred to as the shutdown positioning function).

[0033] In some implementations, the terminal device is shut down by software, which does not completely disconnect the external power supply from the loads in the terminal device in hardware. That is to say, the external power supply of the terminal device is always supplying power to the loads in the terminal device, including but not limited to the communication module, but the interactive interface displayed by the terminal device is in the shutdown state. In this way, the communication module used for positioning in the terminal device can provide the terminal device with the shutdown positioning function based on the power provided by the external power supply. The external power supply includes a lithium battery in the terminal device, etc.

[0034] However, after being shut down using this software shutdown method, the terminal device is still consuming power from the terminal device's external power supply. When the external power supply is exhausted, the external power supply cannot provide power to the communication module of the terminal device, resulting in the communication module of the terminal device being unable to provide the shutdown positioning function for the terminal device.

[0035] In other implementations, the terminal device reserves the required power for the positioning function in the shutdown state, or the terminal device only supplies power to the communication module used for positioning in the shutdown state, so that the communication module can provide the shutdown positioning function for the terminal device based on the power provided by the external power supply. This method of reserving the required power for the positioning function in the shutdown state can support a certain number of positioning, but when the reserved power is exhausted, the communication module of the terminal device will still be unable to provide the shutdown positioning function for the terminal device, thereby failing to meet the user's needs for security and positioning tracing, resulting in a poor user experience.

[0036] In view of this, an embodiment of the present application provides a communication module, including a switching circuit and a passive power supply unit. When the battery power of the terminal device is disconnected, the switching circuit switches to the passive power supply unit to power the communication module. In this way, when the battery power of the terminal device is disconnected or the battery power is exhausted, the communication module can provide the terminal device with a shutdown positioning function based on the power provided by the passive power supply unit, thereby meeting the user's needs for security and positioning tracing, and improving the user experience.

[0037] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0038] For example, Figure 1 The structure of a communication module provided in the embodiment of the present application is shown in FIG. Figure 1 .like Figure 1 As shown, the communication module 100 is in a terminal device, and the terminal device also includes a battery power supply 11 , and the communication module 100 is connected to the battery power supply 11 .

[0039] Specifically, the communication module 100 may include: a passive power supply unit 101, a first switch 201, a second switch 202, a system on chip (SOC) 102, a first resistor R1 and a second resistor R2; the first end of the passive power supply unit 101 is respectively connected to the third end of the first switch 201 and the first end of the second switch 202; the first end of the first resistor R1 is respectively connected to the positive electrode of the battery power supply 11, the first end of the first switch 201 and the third end of the second switch 202; the second end of the first resistor R1 is respectively connected to the first end of the second resistor R2 and the second end of the system on chip SOC 102; the first end of the system on chip SOC 102 is respectively connected to the second end of the first switch 201 and the second end of the second switch 202; the second end of the passive power supply unit 101 is connected to the third end of the system on chip SOC 102. The negative electrode of the battery power supply 11, the second end of the second resistor R2, the third end of the passive power supply unit 101 and the sixth end of the system on chip SOC 102 are all grounded.

[0040] In the embodiments of the present application, the terminal device may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be a mobile phone with a display screen, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, etc.

[0041] The battery power source 11 can be used to supply power to various loads in the terminal device, including but not limited to the communication module 100. Exemplarily, the battery power source 11 can be a lithium battery in the terminal device.

[0042] The passive power supply unit 101 can be used to power the communication module 100 when the power of the battery power supply 11 does not meet the requirement. Exemplarily, the passive power supply unit can be a unit that converts the collected energy into electrical energy, and the collected energy can include one or more energies such as temperature difference energy, vibration energy, radio frequency energy and micro light energy.

[0043] The system-on-chip SOC 102 may be a chip integrating a central processing unit (CPU) and a radio frequency transceiver with cellular communication capability. The system-on-chip SOC 102 may be used to detect a voltage across the second resistor R2, and the voltage across the second resistor R2 is related to a voltage provided by the battery power source 11. Exemplarily, the voltage across the second resistor R2 satisfies the formula:

[0044]

[0045] Among them, U ADC is the voltage across the second resistor R2, R1 is the resistance of the first resistor R1, R2 is the resistance of the second resistor R2, U INPUT The voltage provided by the battery power source 11.

[0046] In the embodiment of the present application, the system-on-chip SOC 102 can also be used to send a control signal to the passive power supply unit 101 based on the detected voltage across the second resistor R2. The passive power supply unit 101 can output a voltage under the action of the control signal, and the on and off of the first switch 201 and the on and off of the second switch 202 can be controlled by combining the voltage output by the battery power supply 11 and the voltage output by the passive power supply unit 101. When the voltage output by the battery power supply 11 is not 0, the second switch 202 is in the on state, and the first switch 201 is in the off state, and the battery power supply 11 is used to power the communication module 100; when the voltage output by the battery power supply 11 is 0, the second switch 202 is in the off state, and the first switch 201 is in the on state, and the passive power supply unit 101 is used to power the communication module 100.

[0047] In the embodiment of the present application, the second end of the passive power supply unit 101 can be connected to the third end of the system-on-chip SOC102 through a CTL line, and the passive power supply unit 101 can periodically send its own status information to the system-on-chip SOC102. The status information may include energy information collected by the passive power supply unit 101, etc.

[0048] In an embodiment of the present application, when the battery power of the terminal device is disconnected or the battery power is exhausted, the communication module can switch to using the power provided by the passive power supply unit through the first switch and the second switch to ensure that the communication module can be powered for a long time even when the terminal device is in the shutdown state, thereby providing sufficient conditions for the communication module to realize the shutdown positioning function of the terminal device, so as to meet the user's needs for security and positioning traceability.

[0049] On the basis of the above embodiments, in order to more clearly describe the communication module provided in the embodiments of the present application, please refer to Figure 2 . For example, Figure 2 The structure of a communication module provided in the embodiment of the present application is shown in FIG. Figure 2 .like Figure 2 As shown, based on the above embodiment, the communication module 100 may further include a third resistor R3, a first end of the third resistor R3 is connected to the first end of the first resistor R1, and a second end of the third resistor R3 is grounded.

[0050] Wherein, the third resistor is a discharge resistor. For example, Figure 2As shown, the first switch 201 can be a P-channel metal oxide semiconductor field effect transistor (positive channel metal oxide semiconductor field-effect transistor, PMOS tube) Q1, and the first end, the second end and the third end of the first switch 201 are respectively the grid (grid, G), the source (source, S) and the drain (drain, D) of the PMOS tube Q1. The second switch 202 can be an N-channel metal oxide semiconductor field effect transistor (negative channel metal oxide semiconductor field-effect transistor, NMOS tube) Q2, and the first end, the second end and the third end of the second switch 202 are respectively the gate, the source and the drain of the NMOS tube Q2. The third resistor R3 can be used to provide a fast discharge path for the gate of the PMOS tube Q1 when the battery power source 11 is disconnected from the communication module 100 or the battery power source 11 is exhausted, so as to protect the PMOS tube Q1.

[0051] Further, under the action of the first control signal of the system-on-chip SOC 102, the first end of the passive power supply unit 101 has a first voltage and the second switch 202 is turned on; under the action of the second control signal of the system-on-chip SOC 102, the first end of the passive power supply unit 101 has a second voltage and the second switch 202 is turned off.

[0052] Exemplarily, the first terminal of the system-on-chip SOC 102 is a voltage pin VBAT pin, and the second terminal of the system-on-chip SOC 102 is an ADC pin, which is used to collect the voltage across the second resistor R2 to detect the output voltage of the battery power source 11 .

[0053] When the voltage output by the battery power source 11 is not 0, the voltage across the second resistor R2 collected by the system-on-chip SOC 102 through the ADC pin is not 0 (the voltage across the second resistor R2 can be determined according to the above formula 1), so the system-on-chip SOC 102 sends a first control signal to the passive power supply unit 101. Under the action of the first control signal, the passive power supply unit 101 outputs a first voltage, which is a high level, so that the voltage difference between the gate of the NMOS tube Q2 and the source of the NMOS tube Q2 (the source voltage of the NMOS tube Q2 is 0) is greater than or equal to the threshold voltage, so that the NMOS tube Q2 is turned on. After the NMOS tube Q2 is turned on, the source voltage of the NMOS tube Q2 becomes the voltage output by the battery power source 11 (assuming it is V1, V1 is not 0). At the same time, since the voltage output by the battery power source 11 is not 0, the voltage difference between the gate of the PMOS tube Q1 and the source of the PMOS tube Q1 is greater than 0 (when the source voltage of the NMOS tube Q2 is 0) or equal to 0 (when the source voltage of the NMOS tube Q2 is the voltage output by the battery power source 11), so that the PMOS tube Q1 is turned off. Therefore, when the voltage output by the battery power source 11 is not 0, the battery power source 11 supplies power to the communication module 100 through the NMOS tube Q2.

[0054] When the voltage output by the battery power source 11 is 0, the voltage across the second resistor R2 collected by the system-level chip SOC 102 through the ADC pin is 0 (the voltage across the second resistor R2 can be determined according to the above formula 1), so the system-level chip SOC 102 sends a second control signal to the passive power supply unit 101, and the passive power supply unit 101 outputs a second voltage under the action of the second control signal, and the second voltage is a continuous high level. Since the voltage output by the battery power source 11 is 0, that is, the gate voltage of the PMOS tube Q1 is 0, the gate voltage of the PMOS tube Q1 is smaller than the source voltage of the PMOS tube Q1 (the source voltage of the PMOS tube Q1 is the source voltage V1 of the NMOS tube Q2), so that the PMOS tube Q1 is turned on. After the PMOS tube Q1 is turned on, the source voltage of the PMOS tube Q1 is the high level output by the passive power supply unit 101, so the source voltage of the NMOS tube Q2 also becomes the high level output by the passive power supply unit 101, and the gate voltage of the NMOS tube Q2 is the voltage output by the passive power supply unit 101, so the gate voltage of the NMOS tube Q2 is equal to the source voltage of the NMOS tube Q2, so that the NMOS tube Q2 is turned off. Therefore, when the output voltage of the battery power supply 11 is 0, the passive power supply unit 101 supplies power to the communication module 100 through the PMOS tube Q1.

[0055] Further, the communication module 100 may also include a device for amplifying the power of a transmitted signal, a device for filtering to retain a desired frequency signal, a device for switching between a transmitted signal and a received signal, and an antenna 106. The first end of the device for amplifying the power of a transmitted signal is connected to the fourth end of the system-on-chip SOC 102, the second end of the device for amplifying the power of a transmitted signal is connected to the first end of the device for filtering to retain a desired frequency signal; the second end of the device for filtering to retain a desired frequency signal is connected to the fifth end of the system-on-chip SOC 102, the third end of the device for filtering to retain a desired frequency signal is connected to the first end of the device for switching between a transmitted signal and a received signal; the second end of the device for switching between a transmitted signal and a received signal is connected to the antenna 106.

[0056] The antenna 106 may be a leaky coaxial cable (also referred to as a leaky cable) having the functions of transmitting and receiving signals.

[0057] Among them, Figure 2 As shown, the device for amplifying the power of the transmission signal may be a power amplifier (PA) chip 103, and the device for switching the transmission signal and the reception signal may be a radio frequency (RF) switch chip 105. The device for filtering to retain the desired frequency signal may be a surface acoustic wave filter (SAW) chip 104, which may also be called a SAW duplexer.

[0058] In an embodiment of the present application, switching of different power supplies is achieved by turning on and off the PMOS tube Q1 and the NMOS tube Q2 in the communication module. When the battery power of the terminal device is disconnected or the battery power is exhausted, the communication module can use the power provided by the passive power supply unit to ensure that the communication module can be powered for a long time even when the terminal device is in the shutdown state, thereby providing sufficient conditions for the communication module to realize the positioning function of the terminal device in the hardware shutdown state, so as to meet the user's needs for security and positioning tracing, and improve the user experience.

[0059] An embodiment of the present application also provides a terminal device, which includes the communication module 100 in the above embodiment.

[0060] Next, a method for implementing the shutdown positioning function of a terminal device by the communication module 100 in an embodiment of the present application is described.

[0061] Exemplarily, the user configures whether to turn on the power-on and power-off positioning function for the terminal device. When the user configures the power-on and power-off positioning function, the communication module 100 can determine whether the battery power supply 11 is disconnected by detecting whether the voltage across the second resistor R2 collected by the system-level chip SOC 102 based on the ADC pin is 0. When the communication module 100 detects that the voltage across the second resistor R2 is not 0, it is determined that the battery power supply 11 is not disconnected and the power is not 0. At this time, the battery power supply 11 supplies power to the communication module 100, and the communication module 100 reports the positioning information to the specific Internet of Things management cloud platform at a first frequency. Among them, the positioning information may include the mobile country code (MCC), mobile network number (MNC), location area code (LAC), base station number CELLID (cell identity, CID) and other information of the network base station cell of the terminal device.

[0062] When the communication module 100 detects that the voltage across the second resistor R2 is 0, it can be determined that the battery power supply 11 is disconnected. At this time, the passive power supply unit 101 supplies power to the communication module 100, and the frequency at which the communication module 100 reports positioning information to a specific IoT management cloud platform is the second frequency.

[0063] It should be noted that the first frequency is greater than the second frequency, so that when the communication module 100 is powered by the battery power supply 11, it can achieve the purpose of timely tracing of positioning information. At the same time, when the communication module 100 is powered by the passive power supply unit 101, it can also achieve the purpose of timely tracing of positioning information and give the passive power supply unit enough time to collect energy for the next positioning information reporting.

[0064] The communication module 100 can obtain the positioning information of the terminal device according to the frequency of reporting the positioning information, and after processing the positioning information as a transmission signal through the PA chip 103 and the SAW chip 104, it is reported to a specific Internet of Things management cloud platform through the RF switch chip 105 and the antenna 106. The Internet of Things management cloud platform can perform further calculations based on the received positioning information to obtain the specific positioning position of the terminal device to which the communication module 100 belongs.

[0065] When the user configures to turn off the shutdown positioning function, the communication module 100 will not report the positioning information.

[0066] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0067] In the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with substantially the same functions and effects. For example, the first resistor and the second resistor are only used to distinguish different resistors, and do not limit their order. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0068] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned implementation modes, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned implementation modes, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation modes of the utility model.
