For details, please refer to FIG. 2 , which is a schematic diagram of a specific embodiment of the system for power supply and channel interface information acquisition of media equipment according to the present invention.

It can be seen that through the power supply and channel interface information acquisition system of media equipment in the present invention, the power supply and channel interface information of multiple media equipment can be quickly obtained, and the media equipment can be further controlled according to the power supply and channel interface information.

Based on the above system, the present invention also provides an acquisition method of the power supply and channel interface information acquisition system. Please refer to FIG. 3 . FIG. 3 is a flowchart of a preferred embodiment of an acquisition method of the power supply and channel interface information acquisition system of the present invention. As shown in Figure 3, the acquisition method of the power supply and channel interface information acquisition system includes the following steps:

Step S100, the control operation module activates and switches all media devices to the working state through the infrared sending interface module, the socket control module and the socket current detection module.

In a preferred embodiment of the present invention, the media device is a set-top box, a DVD, a network set-top box, a game console or an amplifier, that is, a device in a home device that can communicate with a smart TV. When a plurality of media devices are connected to the channel interface of the smart TV, and the media devices are also electrically connected to the wireless smart socket, some of the media devices will directly enter the working state, and some of the media devices also need the infrared remote control to emit infrared The signal wakes up to enter the working state. Step S200 is to initialize the initial states of multiple media devices to the working state. When a certain media device in the plurality of media devices changes from the working state to the standby state, it can be quickly judged that the media device is specifically connected according to the channel signal output state of the smart TV and the change in the current state of the smart socket. Which channel interface to the smart TV and which socket hole to connect to the smart socket.

Step 200, the infrared sending interface module sends infrared remote control instructions to each media device in turn, the media device receives the infrared remote control instructions and switches from the working state to the standby state, and the control operation module inputs the detection module and the The socket current state detection module obtains the state transition information of the channel interface and the socket when each media device changes from the working state to the standby state, and obtains the power supply and channel interface information of the media device according to the state transition information.

As a further embodiment, after each infrared remote control command is sent by the infrared sending interface module in the step S200, the channel input detection module and the socket current state detection module respectively detect the state transition information of the channel interface and the socket and And the state transition information is sent to the operation control operation module, and then the infrared sending interface module sends the next infrared remote control instruction.

That is, in step S200, the infrared remote control command is not sent to multiple media devices at one time, but the infrared remote control command is sent to the multiple media devices sequentially. Assume that there are N media devices that are all communicatively connected to the channel interface of the smart TV, and are also electrically connected to the smart socket. At this time, the N devices are sequentially recorded as media device 1 to media device N, where N is a natural number greater than 1.

In step S200, since all the N multimedia devices have been initialized to the working state, the infrared remote control commands are sent sequentially according to the serial numbers of the media devices. That is, the infrared remote control command is first sent to the media device 1, and the media device 1 changes from the running state to the standby state after receiving the infrared remote control command. At this time, the smart TV will detect no signal input from one of the channel interfaces, and the smart socket will also It will detect that the working current of one of the socket holes has changed to the standby current, so it can quickly determine which channel interface of the smart TV the media device 1 is connected to according to the channel signal output state of the smart TV and the current state of the smart socket. And which socket hole on the smart socket to connect to. After the power supply and channel interface information of the media device 1 are determined, an infrared remote control command is sent to the media device 2, and the power supply and channel interface information of the media device 2 are acquired. The above steps are repeated until the power supply and channel interface information of the media device N is obtained.

Since the infrared remote control signals are sent sequentially according to the numbering sequence of multiple media devices, and the power supply and channel interface information of multiple media devices are obtained sequentially according to the numbering sequence, it effectively reduces the need to first determine which device is targeted at due to random sending of infrared remote control signals. The judgment time of the control signal of a media device reduces the total time consumption for the user to obtain the power supply and channel interface information of multiple media devices at the same time.

In a further embodiment, the power supply and channel interface information is the corresponding relationship between the channel interface of the media device and the smart TV, and the socket of the smart socket. After acquiring the power supply and channel interface information, the display form is as follows: device serial number+jack serial number+channel serial number. In a preferred embodiment of the present invention, since the power supply and channel interface information of a plurality of media devices is only obtained in a certain order in step S200, it is not generated into a list of power supply and channel interface information of a media device , and send the power supply and channel interface information list to other devices for storage, and make further applications according to the power supply and channel interface information list. For example, the power supply and channel interface information list is sent to a smart TV or a mobile smart terminal, and the power supply and channel interface information list is displayed on a display screen of the smart TV or mobile smart terminal. At this time, the user can intuitively see the power supply and channel interface information of each media device. When the user needs to power off a certain media device, he can easily query the media device according to the power supply and channel interface information list. Which socket of the smart socket is plugged in, which greatly facilitates the user.

In a further embodiment, each of the plurality of media devices includes a power-off state, a standby state and a working state. When the smart socket cuts off the power supply to the media device (or the user unplugs the power plug of the media device), the media device enters a power-off state. When the smart socket restores power to the media device, the media device enters a standby state or a working state. If the current state of the media device is in the standby state, it enters the working state when it receives the infrared remote control signal, and enters the standby state when it receives the infrared remote control signal again.

In a further embodiment, as shown in FIG. 4 , in the step S100, activating multiple media devices to the running state specifically includes:

Step S101, the socket control module first cuts off the power supply to all media devices according to the power-off instruction sent by the control operation module, and then the socket control module resumes power supply to all media devices according to the power-on instruction sent by the control operation module. Power supply for media equipment.

Step S102, the control operation module obtains the serial number of the socket whose input current state is the working current in all the sockets through the socket current state detection module, and powers off the socket corresponding to the socket serial number through the socket control module, and then passes the The socket current state detection module judges whether there is a socket in standby current among all the sockets, and if there is, then step S103 is executed, and when there is no socket, then step S104 is executed.

Because some of the media devices in the multiple media devices directly enter the working state when power is supplied, and some other media devices need to receive infrared remote control instructions to wake up to enter the working state, so in step S101, the smart socket first cuts off the N media devices. (That is, all media devices) power supply, and then restore the power supply to N media devices, then M media devices will directly enter the working state at this time, and the remaining (N-M) media devices will enter the standby state. Afterwards, in step S102, the socket current state detection module acquires the socket serial numbers of M media devices entering the working state, and powers off the sockets corresponding to the socket serial numbers through the socket control module, and the above M media devices enter the shutdown state. The remaining (N-M) media devices are still in the standby state. At this time, it is also necessary to judge whether there is a socket in standby current among all the sockets through the socket current state detection module, that is, to judge whether M is equal to N. When M is equal to, it means that the N media devices are all media devices that directly enter the working state after being powered on, and there is no need to send infrared remote control commands to the media devices that are not powered off through the infrared sending interface module to wake them up and enter the working state; When M is not equal to N, it means that there are still (N-M) media devices that enter the standby state directly after being powered on, and step S103 needs to be continued.

Step S103, the infrared sending interface module sequentially sends infrared remote control commands to the media devices that are not powered off, and activates the media devices in the standby state to the working state.

Obviously, except for the M media devices that can directly enter the working state after being powered on, the remaining (N-M) media devices that are not powered off are all in the standby state. At this time, the infrared sending interface module needs to send infrared remote control commands to it sequentially to wake up (N-M) media devices that are not powered off and put them in a working state.

Step S104, the socket control module receives a power-on command to restore power to the media device that has been powered off, and activates the media device that has been powered off to a working state.

When the smart socket receives the power-on command, restores the power supply of the M outlets that were powered off in step S202, and restores the power supply to the M media devices that have been powered off. After the above-mentioned M media devices that have been powered off are powered on Go straight to work. In step S204, when the smart socket receives the power-on command to restore the power supply to the M media devices that have been powered off, it needs to wait for t1 seconds (t1<3), at this time, the status of the power supply sockets of the M media devices that have been powered off All are in a high current state; and when the above M power-off media devices enter the running state, it is necessary to wait for t2 seconds (t1<10) to ensure that the above-mentioned M power-off media devices are all in the running state .

It can be seen from actual tests that the total time-consuming to obtain the four media devices as shown in Figure 2 is 176-224s by using the traditional acquisition method; and the total time-consuming is 176-224s by using the power supply and channel interface information acquisition method of the media device described in the present invention. for 62s. It can be seen that the acquisition method provided by the present invention is a method with low delay and high efficiency.

To sum up, the present invention provides a power supply and channel interface information acquisition system and method for media equipment, the method includes: the control operation module transmits all the information through the infrared transmission interface module, socket control module and socket current detection module The media device is activated and switched to the working state; the infrared sending interface module sends infrared remote control commands to each media device in turn, the media device receives the infrared remote control command and switches from the working state to the standby state, and the control operation module inputs the detection module and the socket through the channel The current state detection module obtains the state transition information of the channel interface and socket when each media device changes from the working state to the standby state, and obtains the power supply and channel interface information of the media device according to the state transition information. Since the waiting time required for repeatedly waiting for the signal input of relevant channel-aware media devices of the smart TV is avoided, the power supply of multiple media devices and the acquisition time of channel interface information are effectively reduced.

It should be understood that the application of the present invention is not limited to the above examples, and those skilled in the art can make improvements or transformations according to the above descriptions, and all these improvements and transformations should belong to the protection scope of the appended claims of the present invention.
