Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The embodiments of the present invention, and all other embodiments obtained by those skilled in the art without any inventive step, belong to the protection scope of the present invention.
Please refer to fig. 1 and fig. 2, which are flowcharts of a wired network control method according to an embodiment of the present invention. As shown in fig. 1, the wired network control method based on the Intel CherryTrail platform includes the following steps:
s10, the controlled end receives a network control instruction sent by the host end through the network and converts the network control instruction into a corresponding power control signal;
and S20, the controlled terminal executes corresponding key operation according to the current working state and the power control signal.
The controlled end and the host end are connected with the network cable, so that wired network connection between the controlled end and the host end is realized. The host terminal sends a network control instruction through the network to simulate the key operation (usually a power key, long press is on/off, short press is sleep/dormant and corresponding wake-up) on the controlled terminal, and the corresponding key function can be realized by combining the current working state of the controlled terminal, so that the host terminal can remotely control the wired network of the controlled terminal.
Before the step S10, the method further includes the steps of: the host computer end prestores key operations corresponding to network control instructions of a plurality of control modes, and the host computer end sends the selected network control instruction after connecting the IP address of the controlled end according to the user operation.
In this step, the key operation is divided into 3 control modes, i.e., power-on corresponding to power-off, sleep corresponding to wake-up, and sleep corresponding to wake-up. The host pre-stores network control commands corresponding to the 3 control modes, for example, the network control command for power on and power off is 01, the network control command for sleep and wake up is 10, and the network control command for sleep and wake up is 11. Based on the characteristic that the control instruction of the Intel CherryTrail platform is single, when the system is actually used, a user can select one mode from a setting interface of a host computer. The host end can be provided with a remote operation function, for example, a corresponding application or program is installed, the remote operation function is started by clicking a remote operation icon, and after the IP address of the controlled end needing to be controlled is connected, a preselected network control instruction can be output and sent to the controlled end through the network.
The host end and the controlled end can be desktops, tablet computers and the like, and are applied to the IOT industry, for example, the host end is a host used by an internet bar manager when applied to an internet bar, the controlled end is an extension used by other users in the internet bar, the host and the extension are connected with a network cable, the host can be connected with the IP address of each extension, and wired network remote control can be carried out on the extension through a network control instruction without walking to each extension. The system can also be applied to multimedia classrooms, the host end is a master control computer used in a teacher office or a monitoring room, the controlled end is a multimedia computer in each classroom, the master control computer can be connected with the IP address of each multimedia computer, and if the multimedia computers are not powered off, the master control computer can send a network control instruction to power off the multimedia computers without going to each classroom; correspondingly, the multimedia computer in the classroom to be used can be uniformly started before the class in the morning. As long as the IP address of the controlled end can be connected and the controlled end is based on the Intel CherryTrail platform, the controlled end can be remotely controlled through the wired network by the host end.
Before step S10, when the controlled end does not receive the network control instruction sent by the host end through the network, the controlled end is in a standby state, that is, the network card 110 in the controlled end outputs a high-level (3.3V) WAKE-up signal PCIE _ WAKE # to the single chip microcomputer 120, the single chip microcomputer 120 drives and strengthens the WAKE-up signal PCIE _ WAKE # and then outputs a high-level (1.8V) Power control signal Power button to the processor, and at this time, the processor 20 is in a standby state.
After the controlled end receives a network control instruction sent by the host end through the network, the network card 110 converts the received network control instruction (digital signal) into an analog low-level (0V) single-pulse WAKE-up signal PCIE _ WAKE # (that is, only one low-level pulse is present), and the single chip microcomputer 120 drives and strengthens (i.e., delays) the WAKE-up signal PCIE _ WAKE #, and then outputs a low-level (0V) single-pulse Power control signal Power button to the processor 20. When the network control command is 01, 10, and 11, the durations of the low levels of the WAKE-up signal PCIE _ WAKE # converted by the network card 110 are different, and the extension time of the low level of the single chip microcomputer 120 is a set value, and can be extended in equal proportion, for example, the duration of the low level pulse of the WAKE-up signal PCIE _ WAKE # converted by the network control command 01 is 30 milliseconds, and is extended to 3 seconds by the single chip microcomputer 120, which indicates to turn on or off the computer; the low-level pulse duration of the WAKE-up signal PCIE _ WAKE # converted by the network control instruction 10 is 10 milliseconds, and is extended to 1 second by the single chip microcomputer 120, which indicates sleep or WAKE-up; the low-level pulse duration of the WAKE-up signal PCIE _ WAKE # converted by the network control instruction 11 is 20 milliseconds, and is extended to 2 seconds by the single chip microcomputer 120, which indicates sleep or WAKE-up. The time values are only examples, and the setting can be modified according to actual requirements.
In step S20, after the processor 20 receives the Power control signal Power button, it can determine which control mode is according to the duration of the low level pulse, and then, in combination with the current working state of the controlled terminal, execute the corresponding key operation. The method specifically comprises the following steps:
step 21, the processor of the controlled terminal judges whether the duration time of the low level of the power control signal is less than a first threshold (such as 1.5 seconds), if yes, the processor executes a first key operation (sleep or wake-up) according to the current working state; otherwise, executing step 22;
step 22, judging whether the duration time of the low level of the power supply control signal is greater than a first threshold (such as 1.5 seconds) and less than a second threshold (such as 2.5 seconds), if so, executing a second key operation (sleeping or awakening) according to the current working state; otherwise, executing step 23;
and step 23, judging whether the duration time of the low level of the power supply control signal is greater than a second threshold (for example, 2.5 seconds), if so, executing a third key operation (power on or power off) according to the current working state.
For example, a network control instruction 01 corresponding to Power-off when the network is started is sent, if the controlled end is currently in the Power-off state, the network card receives the instruction 01 and converts the instruction into a WAKE-up signal PCIE _ WAKE # with a low level pulse duration of 30 milliseconds, and then the WAKE-up signal Power button is extended to 3 seconds by the single chip microcomputer 120, the processor detects that the duration of the low level is greater than a second threshold (for example, 2.5 seconds) and recognizes that the WAKE-up signal is a key operation for starting up or powering off, and if the controlled end is currently in the Power-off state, the network card only executes the Power-on operation; if the power-on state exists, only the power-off operation is executed after 01 is received.
Similarly, if the network control instruction 10 corresponding to wake-up during sleep is supposed to be sent, if the controlled end is currently in a working state, only the sleep operation is executed after receiving the network control instruction 10; if the terminal is in the sleep state, only the awakening operation is executed after receiving 10 times of the terminal, and the controlled terminal is in the working state after awakening. Supposing that a network control instruction 11 corresponding to awakening from sleep is sent, if the controlled end is currently in a working state, only the sleep operation is executed after the controlled end receives the instruction 11; if the terminal is in the dormant state, only the awakening operation is executed after the terminal receives the message 11, and the controlled terminal is in the working state after the awakening operation.
After the step S20, the method further includes a step S30, and after the key operation is completed, the state is restored to the standby control state.
After the remote control is completed, the network card 110 in the controlled end recovers the WAKE-up signal PCIE _ WAKE # to a high level (3.3V) and transmits the WAKE-up signal PCIE _ WAKE # to the single chip microcomputer 120, the single chip microcomputer 120 drives and strengthens the WAKE-up signal PCIE _ WAKE # and then outputs a Power button of the high level (1.8V) to the processor, and at this time, the controlled end waits for receiving a next network control instruction.
On the basis of the above method for controlling a wired network, the present embodiment further discloses a terminal device (i.e., a controlled end), please refer to fig. 2, where the controlled end includes: the signal conversion module 10 receives a network control instruction sent by a host end through a network and converts the network control instruction into a corresponding power control signal, and the processor 20 executes a corresponding key operation according to the current working state and the power control signal.
The signal conversion module 10 includes a network card 110 and a single chip microcomputer 120, the network card 110 receives a network control instruction sent by a host through a network and converts the network control instruction into an analog low-level (0V) single-pulse WAKE-up signal PCIE _ WAKE # (that is, only one low-level pulse is present), and the single chip microcomputer 120 drives and strengthens (that is, delays, prolongs the duration of the low-level pulse) the WAKE-up signal PCIE _ WAKE #, and then outputs a low-level (0V) single-pulse Power control signal Power button to the processor. The level duration of the wake-up signal converted by the network card 110 is short, and the processor cannot respond in time, so that the duration of the level is prolonged by the single chip microcomputer, the duration of the pressed power key can be simulated, and the processor can accurately identify the corresponding key operation.
On the basis of disclosing the terminal device, the embodiment further discloses a control system, please continue to refer to fig. 2, the control system comprises a controlled end and a host end, the host end is connected with the controlled end according to the IP address of the controlled end, and sends a network control instruction to the controlled end through a network; and the controlled end receives the network control instruction and converts the network control instruction into a corresponding power control signal, and executes corresponding key operation according to the current working state and the power control signal.
