Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 1 and fig. 2, a low power consumption control method for a WWAN electronic device 100 is provided in an embodiment of the invention. The electronic device 100 includes an interface control circuit 102, and the interface control circuit 102 is used for connecting a wireless network card 104. The control method comprises the following steps:
step S10: judging whether the electronic device 100 is in a dormant state;
step S20: sending a disconnection control signal to the interface control circuit 102 in a case where the electronic apparatus 100 is in the sleep state;
step S30: the interface control circuit 102 disconnects the electrical connection with the wireless network card 104 according to the disconnection control signal.
According to the control method of the electronic device 100 of the embodiment of the invention, under the condition that the electronic device 100 is in the dormant state, the interface control circuit 102 can be disconnected from the wireless network card 104, so that the low power consumption of the electronic device 100 is realized, and the service life of the wireless network card 104 is prolonged.
Specifically, the interface control circuit 102 may be built in a motherboard circuit of the electronic device 100, and is used for controlling the electrical connection between the electronic device 100 and the wireless network card 104. In one example, when the electronic device 100 is in a sleep state, the screen of the electronic device 100 is not illuminated. The interface control circuit 102 disconnects the electrical connection with the wireless network card 104 after receiving the disconnection control signal. At this time, the wireless network card 104 does not perform data transmission with the electronic device 100. When the wireless network card 104 enters the low power consumption state, the time of using the power supply 110 in the electronic device 100 may be reduced, thereby implementing low power consumption of the electronic device 100.
In addition, under the condition that the interface control circuit 102 is electrically disconnected from the wireless network card 104, the power supply 110 can be kept to supply power to the wireless network card 104, so that the wireless network card 104 can be ensured to enter a low power consumption state under the condition of no power failure, and the frequent switching of the power-on state and the power-off state of the wireless network card 104 caused by the frequent switching of the working state and the sleep state of the electronic device 100 can be avoided, thereby avoiding the abnormality of the wireless network card 104. For determining whether the electronic device 100 is in the sleep state or the working state, reference is made to related technologies, which are not described herein again.
It should be noted that the electronic device 100 may be a wireless terminal device, such as a personal computer, a notebook, a tablet computer, etc., to which the wireless network card 104 can be connected. The Wireless Network card 104 may be an LTE WWAN (Wireless Wide Area Network) Wireless Network card. It can be understood that, in an environment where the electronic device 100 cannot be connected to the wired broadband network, the wireless network card 104 may be connected to obtain the network signal, so that the electronic device 100 may perform network communication.
Referring to fig. 3, in some embodiments, the control method includes:
step S22: sending a conduction control signal to the interface control circuit 102 when the electronic device 100 is in a working state;
step S24: the interface control circuit 102 is electrically connected to the wireless network card 104 according to the conduction control signal.
Specifically, in one example, when the electronic device 100 is in an operational state, a screen of the electronic device 100 is bright. The interface control circuit 102 receives the connection control signal and then connects the electrical connection with the wireless network card 104. At this time, the wireless network card 104 performs data transmission with the host 106, and the wireless network card 104 normally operates and is in a normal power consumption state.
In the present invention, the working state of the wireless network card 104 is controlled by the on/off of the interface control circuit 102, and the wireless network card 104 can be controlled to work normally at any time. When the electronic device 100 is in the sleep state, the interface control circuit 102 disconnects the electrical connection with the wireless network card 104, and the wireless network card 104 is in the low power consumption state. When the electronic device 100 is in a working state, the interface control circuit 102 is electrically connected to the wireless network card 104, the wireless network card 104 can be used normally to provide wireless data, and at this time, the wireless network card 104 is in a normal power consumption state. The wireless network card 104 and the electronic device 100 are switched to a normal working state together, and no time delay is generated. In this way, the user can use the wireless network card 104 in time.
In some embodiments, the electronic device 100 includes a host 106, and the interface control circuit 102 is coupled to the host 106 via a USB protocol. The host 106 may be a host of a personal computer.
It is understood that the USB protocol is a communication protocol that supports serial data transfer between the USB host 106 and the USB device. The wireless network card 104 is connected to the host 106 of the electronic device 100 through the interface control circuit 102, and can perform data transmission through the USB protocol.
Specifically, referring to fig. 4, the host has a USB interface 108, the interface control circuit 102 is connected to the USB interface 108, and the wireless network card 104 is inserted into the USB interface 108.
In this manner, the wireless network card 104 is connected to the interface control circuit 102 via the USB interface 108. The interface control circuit 102 may control the connection and disconnection of the wireless network card 104 to and from the USB interface 108.
Referring to fig. 4, in some embodiments, the electronic device 100 includes a power supply 110, and the interface control circuit 102 and the wireless network card 104 are connected to the power supply 110. The control method comprises the following steps:
when the interface control circuit 102 is electrically disconnected from the wireless network card 104, the power supply 110 is kept supplying power to the wireless network card 104.
It is understood that the power supply 110 provides power to the interface control circuit 102 and the wireless network card 104. The electrical connection between the wireless network card 104 and the power supply 110 is not limited by the interface control circuit 102. When the wireless network card 104 is plugged into the USB interface 108 of the electronic device 100, the power supply 110 can supply power to the wireless network card 104 to ensure that the wireless network card 104 is in a power-on state.
The following experimental tests show that the control method of the electronic device 100 according to the embodiment of the present invention can achieve low power consumption of the electronic device 100. Referring to fig. 5, the wireless network card 206 is connected to the host 202 of the electronic device through the USB interface 204, and the wireless network card 206 is connected to the power supply 300 for testing. Referring to fig. 6, the wireless network card 104 is connected to the host 106 of the electronic device 100 through the interface control circuit 102, and the wireless network card 104 and the interface control circuit 102 are connected to the power supply 300 for testing. Fig. 5 is a circuit schematic diagram of the electronic apparatus 100 of the related art; fig. 6 is a circuit schematic diagram of the electronic device 100 according to the embodiment of the invention.
Under the condition that the electronic equipment is in a working state, the wireless network card is independently powered through the test power supply 300, and the current consumption of the wireless network card is tested. The current consumption of the circuits in fig. 5 and fig. 6 are the same, which shows that the interface control circuit is in an operating state, and no additional current consumption is added. And under the condition that the electronic equipment is in a dormant state, the wireless network card is independently powered by the power supply for testing. The circuit shown in FIG. 6, the lumen consumption of the wireless network card is significantly reduced. For specific experimental test data, please refer to the following table:
