For the convenience of understanding the embodiment, a detailed description will be given to a mobile terminal disclosed in the embodiment of the present invention.
Referring to a schematic structural diagram of a mobile terminal shown in fig. 1, the mobile terminal 10 includes: a processor 11, a first controller 12, a data path switch 13 and a power switch 14; the power supply changeover switch 14 is respectively connected with the first controller 12 and the processor 11; in the initial state, the data path selector switch 13 is connected to the processor 11; the processor 11 is connected with a power supply battery 15 on the mobile terminal through a power supply changeover switch 14.
The mobile terminal may be a mobile device or a mobile phone, and the mobile terminal generally includes a peripheral subsystem composed of a display module, a storage module, an audio module, a radio frequency module, an antenna, and other modules besides the processor 11, the first controller 12, the data path switch 13, and the power switch 14, and the peripheral subsystem is connected to the processor 11; the processor 11 can be generally understood as a final execution Unit for Processing information, data, and the like, such as a Central Processing Unit (CPU) or the like; the first controller 12 may be a control unit that outputs a corresponding control signal according to a received command; a control unit such as a control chip or an integrated circuit; the data path changeover switch 13 may be a switch that can switch two or more data paths; such as a USB data switch; the power supply changeover switch 14 may be understood as a switch that can switch between two or more power supply paths; if the power supply switches the alternative switch; in an initial state, the data path selector switch 13 is respectively connected with the processor 11 and the peripheral subsystem; the processor 11 and the peripheral subsystems are connected with a power supply battery 15 on the mobile terminal through a power supply changeover switch 14, namely, the processor 11 and the peripheral subsystems are powered by the power supply battery 15 on the mobile terminal.
The data path switching switch 13 is configured to receive an external test signal and transmit the test signal to the processor 11.
The test signal can be understood as a test script corresponding to the mobile terminal to be tested, which is sent by an external test device, such as a test instrument or a test fixture, and the test script includes information such as specific voltage and current required for power consumption test; in the initial state, since the data path changeover switch 13 is in a connected state with the processor 11, the data path changeover switch 13 transmits the received external test signal to the processor 11.
The processor 11 and the first controller 12 are configured to verify the test signal, and if the test signal passes the verification, control the power switch 14 to be switched from the power supply battery 15 to an external power supply, so as to supply power to the processor 11 and the peripheral subsystems through the external power supply.
In this embodiment, the input end of the power switch 14 may include two power supply paths, where one power supply path is powered by the power supply battery 15 on the mobile terminal, and the other power supply path is powered by the external power supply; it should be noted that the two power supply modes do not usually supply power to the processor 11 and the peripheral subsystem at the same time, and one of the two power supply modes is selected to supply power to the processor 11 and the peripheral subsystem according to different situations; after the processor 11 receives the external test signal, the processor 11 and the first controller 12 may verify the test signal, for example, determine whether the serial number of the mobile terminal to be tested is correct, or determine whether the mobile terminal can accurately receive the test signal, and if the verification passes, control the power switch 14 to switch from the power supply battery 15 connected in the initial state to the external power supply, and supply power to the processor 11 and the peripheral subsystem through the external power supply.
The processor 11 is configured to perform a power consumption test on the mobile terminal according to the test signal in a state of power being supplied by an external power source. When the power supply of the processor 11 is switched to the state of external power supply, the processor 11 performs a power consumption test on the mobile terminal to be tested according to the test signal received in the initial state.
The embodiment of the invention provides a mobile terminal, which comprises: the device comprises a processor, a first controller, a data path change-over switch and a power supply change-over switch; the data path change-over switch receives an external test signal and sends the test signal to the processor; the processor and the first controller verify the test signal, and if the test signal passes the verification, the power supply changeover switch is controlled to be switched from the power supply battery to an external power supply so as to supply power to the processor through the external power supply; and the processor performs power consumption test on the mobile terminal according to the test signal in the state of power supply of the external power supply. The mobile terminal is internally integrated with the first controller, the data path change-over switch and the power supply change-over switch, when power consumption testing is needed, verification or switching of a testing signal and a power supply can be completed inside the mobile terminal, so that disassembly is not needed, power consumption testing can be achieved, testing efficiency is improved, debugging and fault analysis efficiency of the mobile terminal is improved, and mass testing is easy to achieve.
Further, referring to another structure diagram of the mobile terminal shown in fig. 2, the processor 11 is configured to perform a first verification process on the test signal, and if the verification passes, control the datapath switch 13 to connect to the first controller 12, and send the test signal to the first controller 12; the first controller 12 is used for performing a second verification process on the test signal, and if the verification is passed, the power switch 14 is controlled to be switched from the power supply battery 15 to an external power supply, so as to supply power to the processor 11 and the peripheral subsystems through the external power supply.
In an initial state, the processor 11 first performs a first verification process on a received test signal, for example, whether a serial number of a mobile terminal to be tested is correct or not is confirmed, or whether the received test signal is correct or not is confirmed, and if the first verification is passed, the processor 11 usually outputs a data path switching control signal, such as a USB data switching control signal, and controls the data path switching switch 13 to be connected to the first controller 12, so as to send the data signal to the first controller 12; in order to further enhance the identity verification and ensure the accuracy and safety of the test, after receiving the test signal, the first controller 12 may perform a second verification process on the received test signal, the verification content and the verification process may be the same as those in the first verification process, if the second verification passes, the second controller outputs a power switching control signal to control the power switch 14 to be switched from the power supply battery 15 to the external power supply, so as to supply power to the processor 11 and the peripheral subsystem through the external power supply.
In practical implementation, the test signal may be a USB data signal DP/DN; the data path switch 13 may be a USB data switch, and the output end of the data path switch may include two data paths, that is, a data path 1 and a data path 2, the data path switch 13 is connected to the processor 11 through the data path 1, and the data path switch 13 is connected to the first controller 12 through the data path 2; the power supply switch 14 can be an alternative switch for switching power supply; the first authentication process may be understood as one-time handshake and authentication; the second authentication process may be understood as a secondary handshake and authentication; the external power source may be denoted as VTEST; the power supply provided by the supply battery 15 may be denoted VBATT; the first controller 12 may also be denoted as an MCU (Microcontroller Unit) controller 1.
During the first verification process and the second verification process, it is usually necessary to verify the identity information of the mobile terminal to distinguish it from other devices, so as to ensure that the received test signal matches the mobile terminal, for example: when a plurality of different mobile terminals need to receive test signals at the same time, the test signals required by each mobile terminal are usually different, so that the identity of the mobile terminal needs to be confirmed to ensure that the mobile terminal receives correct test signals, and the test is accurate and safe; in practical implementation, the ID number of the mobile terminal is usually adopted for identity verification, the ID number corresponds to the mobile terminal one to one, the name of the test signal can include the ID number of the corresponding mobile terminal for differentiation, and when the ID number of the mobile terminal to be tested is consistent with the ID number included in the name of the test signal, the mobile terminal will receive the test signal.
In addition, in the first verification process and the second verification process, it is usually necessary to determine whether the mobile terminal can accurately receive the test signal; the data packet in the test signal usually includes a PID (Process Identifier, also called a packet Identifier) to identify the data packet in the test signal, and when the mobile terminal receives the test signal including the PID, the mobile terminal outputs a feedback signal, and if the feedback signal is a signal indicating successful reception, such as an ACK (Acknowledge character) signal, the mobile terminal may successfully transmit the test signal, and the mobile terminal may accurately receive the test signal; if the feedback signal is a signal indicating reception failure, such as a NAK (no acknowledgement) signal, the test signal transmission fails, or the test signal transmission succeeds, but the mobile terminal cannot accurately receive the test signal.
In this embodiment, the first controller 12 may be a relatively independent device, and has stable function and high reliability, and it can be ensured that power failure problems such as voltage drop and the like do not occur in the power switching process, so that the first controller 12 can output stable control signals, such as power switching control signals, to ensure the reliability of power switching.
Further, the first controller 12 is further configured to detect whether the external power supply meets a preset voltage; if the external power supply meets the preset voltage and the result of the second verification processing of the test signal by the first controller 12 is verification pass, the power switch 14 is controlled to be switched from the power supply battery 15 to the external power supply so as to supply power to the processor 11 and the peripheral subsystems through the external power supply.
In practical implementation, different mobile terminals usually have different requirements for power supply of an external power supply due to differences in test requirements, so that a preset voltage is usually set for the external power supply according to the real-time test requirements of the mobile terminals, and the preset voltage may be a specific voltage value or a voltage range defined based on the specific voltage value; in order to ensure that the external power supply meets the test requirement, the first controller 12 may detect whether the external power supply meets a preset voltage, if the external power supply meets the preset voltage, and at the same time, the second verification processing result of the first controller 12 on the test signal is verification passing, the first controller 12 outputs a power supply switching control signal, controls the power supply switch 14 to be switched from the power supply battery 15 to the external power supply, so as to supply power to the processor 11 and the peripheral subsystem through the external power supply; if the external power supply does not meet the preset voltage, or the result of the second verification processing on the test signal by the first controller 12 is verification failure while the external power supply does not meet the preset voltage, the first controller 12 does not output the power supply switching control signal.
Further, the processor 11 is further configured to: if a new test signal is received, the data path switch 13 is controlled to be connected to the processor 11, so that the processor 11 receives the new test signal.
In practical implementation, when the data path switch 13 is switched to the first controller 12, and the second verification process is completed, and the external power source is switched, the connection state is usually maintained during the practical power consumption test; if the datapath changing-over switch 13 receives a new test signal, the processor 11 will control the datapath changing-over switch 13 to be connected to the processor 11 again, so that the processor 11 receives the new test signal to perform the power consumption test on the mobile terminal according to the new test signal.
Further, the mobile terminal further includes a power supply battery 15; the power supply battery 15 is respectively connected with the first controller 12, the data path switch 13 and the power switch 14, and is used for supplying power to the first controller 12, the data path switch 13, the processor 11 and the peripheral subsystems which are connected with the power switch 14.
