The mode is carried out manually and off-line, so that the state value of the terminal equipment cannot be captured dynamically in real time, and the terminal equipment cannot interact with the measuring process.

Detailed Description
One or more embodiments of the present disclosure provide a system and a method for measuring power consumption of a terminal device, so as to solve the problems that the power measurement of the terminal device in the prior art cannot interact with the terminal device and the measurement is inaccurate.
In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.
Fig. 1 is a schematic block diagram of a terminal device power consumption measurement system according to an embodiment of the present specification, and as shown in fig. 1, the system includes a main control device 110 and a power consumption measurement apparatus 120, which are used for measuring power consumption of a terminal device 130 connected with a dummy battery. The connection between the terminal device 130 and the dummy battery may be: the terminal device 130 externally connects a dummy battery by using an adaptive wire; alternatively, the dummy battery is built into the terminal device 130 and replaces the primary battery in the terminal device 130 (fig. 1 only shows a case where the dummy battery is built into the terminal device).
In the terminal equipment power consumption measuring system, the USB interface of the power consumption measuring device 120 is connected with the USB interface of the terminal equipment 130; the positive terminal of the power consumption measuring device 120 is connected with the positive terminal of the dummy battery, the negative terminal is connected with the grounding terminal of the system, the negative terminal is connected with the negative terminal of the dummy battery through the fuel gauge in the power consumption measuring device 120, and the grounding terminal of the USB interface of the power consumption measuring device 120 is connected with the fuel gauge.
In the power consumption measurement process, the main control device 110 sends a power consumption measurement instruction to the power consumption measurement apparatus 120, where the power consumption measurement instruction is used to instruct the power consumption measurement apparatus 120 to perform power consumption measurement on the terminal device 130. The power consumption measurement device 120 acquires the actual power consumption amount of the terminal device 130 during the power consumption measurement process, and displays the acquired actual power consumption amount on the electricity meter. And, transmitting the actual amount of power consumed to the master control device 110. The main control device 110 determines the power consumption of the terminal device 130 according to the actual power consumption amount.
In this embodiment, the actual power consumption is the sum of the first power consumed by the terminal device 130 during the power consumption measurement process and the second power generated by supplying power to the terminal device 130 through the USB interface of the power consumption measurement apparatus 120. The actual amount of power consumed by the terminal device 130 during the power consumption measurement process may include at least one of: power consumed by an operating system of the terminal device 130, power consumed by an application installed on the terminal device 130. The first electric quantity consumed by the terminal device 130 in the power consumption measurement process includes not only the actual consumed electric quantity, but also the electric quantity supplement caused by the second electric quantity, and the electric quantity supplement makes the first electric quantity consumed by the terminal device 130 in the power consumption measurement process smaller than the actual consumed electric quantity, and the deviation value is the second electric quantity generated by supplying power to the terminal device 130 through the USB interface of the power consumption measurement apparatus 120.
Specifically, the relationship between the actual consumption electric quantity and the first and second electric quantities may be expressed as: the actual consumed electric quantity is equal to the first electric quantity + the second electric quantity. Assuming that the first power amount consumed by the terminal device 130 is a and the power supply amount supplied to the terminal device 130 through the USB interface of the power consumption measuring apparatus 120 is b in the data counted by the electricity meter, both values flow into the electricity meter, so that the value counted by the electricity meter is the integrated value of the two values, i.e., a + b.
By adopting the power consumption measurement system of the terminal device in the embodiment, the main control device sends the instruction for measuring the power consumption of the terminal device to the power consumption measurement device connected with the main control device, so that the terminal device can obtain the actual power consumption of the terminal device in the power consumption measurement process based on the instruction. In the power consumption measurement process, the USB interface of the power consumption measurement device is always connected with the USB interface of the terminal equipment, and the grounding end of the USB interface of the power consumption measurement device is connected with the electricity meter in the power consumption measurement device, so that the actual power consumption obtained by the power consumption measurement device is the sum of the first power consumption consumed by the terminal equipment and the second power generated by supplying power to the terminal equipment through the USB interface of the power consumption measurement device, namely the actual power consumption does not contain the power supplement caused by the power supply of the USB interface of the power consumption measurement device to the terminal equipment. Therefore, the power consumption measuring method of the system for the terminal equipment can not only dynamically capture the state value of the terminal equipment in real time under the condition of not influencing the USB signal interaction of the terminal equipment, but also improve the accuracy of the power consumption measuring result.
In the above embodiment, the ground terminal of the USB interface of the power consumption measuring device 120 may be connected to the electricity meter in an indirect manner or a direct manner. The following description will be made for each of these two connection methods.
In one embodiment, the ground terminal of the USB interface of the power consumption measuring device 120 is indirectly connected to the electricity meter. As shown in fig. 2, the ground terminal of the USB interface of the power consumption measuring apparatus 120 is connected to the ground terminal of the system through a switch 121, and the switch 121 is opened or closed according to a control signal from the main control device 110. Since the ground terminal of the system is connected to the electricity meter, indirect connection between the ground terminal of the USB interface of the power consumption measuring device 120 and the electricity meter is achieved. The power consumption measuring apparatus 120 further includes a microcontroller, and the microcontroller is connected to the main control device 110, the electricity meter, and the switch 121, respectively. The USB interface of the power consumption measuring device 120 includes a D + connection line and a D-connection line, and the D + connection line and the D-connection line are respectively used for connecting with a D + signal line and a D-signal line of the USB interface of the terminal device 130, so that USB signal interaction is performed between the power consumption measuring device 120 and the terminal device 130. The arrows on the connecting lines in fig. 2 indicate the signal flow direction.
The microcontroller controls the switch 121 to be opened during the power consumption measurement process according to the received control signal from the main control device 110, so as to disconnect the USB interface of the power consumption measurement apparatus 120 from the ground of the system, and controls the switch 121 to be closed at the end of the power consumption measurement process.
In this embodiment, during power consumption measurement, the microcontroller controls the switch 121 to be turned off, and at this time, the connection between the USB interface of the power consumption measurement apparatus 120 and the ground terminal of the system is turned off, so that all signals output by the USB interface of the power consumption measurement apparatus 120 sequentially flow into the electricity meter through the USB interface of the terminal device 130 and the negative electrode of the dummy battery, where the signals include an interaction signal passing through the USB interface and a charging current for the terminal device 130. Therefore, the electricity meter can count the actual consumed electricity amount of the terminal device 130, i.e., the sum of the first electricity amount consumed by the terminal device 130 during the power consumption measurement and the second electricity amount generated by supplying power to the terminal device 130 through the USB interface of the power consumption measurement apparatus 120.
In addition, in this embodiment, the microcontroller closes the control switch 121 when the power consumption measurement process is finished according to the received control signal from the main control device 110, so that when the power consumption measurement device 120 does not measure the terminal device 130, the ground terminal of the USB interface of the power consumption measurement device 120 is directly connected to the ground terminal of the system, thereby meeting the requirement of the D + connection line and the D-connection line of the USB interface on the backflow ground, reducing the interference of the outside on the USB signal interacted between the power consumption measurement device 120 and the terminal device 130, and ensuring the smooth signal communication of the USB interface.
In one embodiment, as shown in fig. 3, the ground terminal of the USB interface of the power consumption measuring device 120 is directly connected to the electricity meter. The power consumption measuring apparatus 120 further includes a microcontroller, and the microcontroller is connected to the main control device 110 and the electricity meter, respectively. The USB interface of the power consumption measuring device 120 includes a D + connection line and a D-connection line, and the D + connection line and the D-connection line are respectively used for connecting with a D + signal line and a D-signal line of the USB interface of the terminal device 130, so that USB signal interaction is performed between the power consumption measuring device 120 and the terminal device 130. The arrows on the connecting lines in fig. 3 indicate the signal flow direction.
In this embodiment, since the ground terminal of the USB interface of the power consumption measuring device 120 is directly connected to the electricity meter, all signals output by the USB interface of the power consumption measuring device 120 may be forced to flow into the electricity meter, where the signals include the interactive signals passing through the USB interface and the charging current for the terminal device 130, so that the electricity meter can count the actual power consumption of the terminal device 130, that is, the sum of the first power consumed by the terminal device 130 during the power consumption measurement and the second power generated by supplying power to the terminal device 130 through the USB interface of the power consumption measuring device 120.
In addition, in this embodiment, since the ground terminal of the USB interface of the power consumption measurement device 120 is connected to the ground terminal of the system through the electricity meter, the requirement of the D + connection line and the D-connection line of the USB interface for the return ground can be met, the interference of the outside on the USB signal interacted between the power consumption measurement device 120 and the terminal device 130 is reduced, and the smooth signal communication of the USB interface is ensured.
Therefore, no matter which connection mode shown in fig. 2 or fig. 3 is adopted, the power consumption measurement apparatus 120 can calculate the actual power consumption of the terminal device 130 through the electricity meter, so that the accuracy of the power consumption measurement result of the terminal device is greatly improved, and the USB signal interaction of the terminal device in the power consumption measurement process is not affected.

As shown in fig. 4, the method is applied to the power consumption measuring apparatus 120 according to any of the above embodiments, and includes the following steps:

Specifically, the relationship between the actual consumption electric quantity and the first and second electric quantities may be expressed as: the actual consumed electric quantity is equal to the first electric quantity + the second electric quantity.
And S406, sending the actual consumed electric quantity to the main control equipment, so that the main control equipment determines the power consumption of the terminal equipment according to the actual consumed electric quantity.
In an embodiment, before receiving the power consumption measurement instruction sent by the master device, a first control signal sent by the master device may be received, where the first control signal is used to control a switch (such as the switch 121 shown in fig. 2) to be disconnected during the power consumption measurement process, so as to disconnect the USB interface of the power consumption measurement apparatus from the ground terminal of the system; and then based on the first control signal, the switch is controlled to be switched off.
In one embodiment, after the actual power consumption amount is sent to the master device, a second control signal sent by the master device may be received, where the second control signal is used to control a switch (e.g., the switch 121 shown in fig. 2) to be closed at the end of the power consumption measurement process; and then based on the second control signal, the switch is controlled to be closed.

Specifically, the relationship between the actual consumption electric quantity and the first and second electric quantities may be expressed as: the actual consumed electric quantity is equal to the first electric quantity + the second electric quantity.
And S506, determining the power consumption of the terminal equipment according to the actual power consumption.

In one embodiment, after receiving the actual power consumption amount of the terminal device returned by the power consumption measurement device in the power consumption measurement process, the terminal device may send a second control signal to the power consumption measurement device, where the second control signal is used to control the switch to be closed at the end of the power consumption measurement process.
