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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, fig. 1 is a flowchart of a first embodiment of a signal transmission processing method provided in the present application, where the method is applicable to a control device based on a predetermined transmission interface, for example, the method is particularly applicable to a docking station based on a type-C interface, so as to solve a problem that a docking station in the prior art cannot implement effective transmission of a docking station power button signal through the type-C interface, and further cannot perform state control such as turning on, turning off, or sleeping on a computer device such as a notebook computer through the type-C interface, as shown in fig. 1, the method may include the following steps:
s101: an original control signal of the control device is obtained.
For example, the original control signal of the control device may specifically be a power button signal of the control device, and taking the docking station based on the type-C interface as an example, the control signal may specifically be a power-on signal, a power-off signal, a hibernation signal, or the like, which is triggered by a user operating a power button of the docking station.
In practical applications, the original control signal of the control device may be detected and obtained by using a corresponding detecting device, for example, in a docking station based on a Type-C interface, a Power-on/off signal or a sleep signal triggered by a user at a Power button of the docking station may be detected and obtained by using a Type-C dock PD IC (Power Delivery integrated circuit of the docking station), where the Type-C dock PD IC is mainly responsible for signal communication between the Type-C interface and the docking station.
S102: and carrying out preset signal conversion processing on the original control signal to obtain a control signal meeting the data requirement of the preset transmission interface.
After obtaining the original control signal of the control device, based on the data specification supported by the predetermined transmission interface of the control device, such as the supported signal form, data format, and the like, the original control signal may be subjected to corresponding signal conversion processing, so that the original control signal is converted into the control signal meeting the data requirement of the predetermined transmission interface, and further, the transmission of the control signal can be supported at the predetermined transmission interface.
In the docking station based on the type-C interface, a power button signal of the docking station needs to be converted into a control signal which can be supported by the type-C interface.
S103: and transmitting the control signal to a control object by using the preset transmission interface.
Finally, the control signal according with the data requirement (predetermined transmission interface) of the control device can be transmitted to the control object by using the predetermined transmission interface of the control device, so that the control device can control the control object based on the predetermined transmission interface. For the docking station based on the type-C interface, the type-C interface can perform corresponding signal conversion processing on the power button signal of the docking station, so that the type-C interface based on the docking station can perform effective transmission of the power button signal (converted on/off or sleep signal) to the control object such as the notebook computer, and the like, and further the docking station can perform state control such as on/off or sleep on the computer equipment such as the notebook computer and the like at the power button thereof based on the type-C interface.
According to the above scheme, the present application provides a signal transmission processing method, which is applicable to a control device based on a predetermined transmission interface, and the method includes obtaining an original control signal of the control device; performing preset signal conversion processing on the original control signal to obtain a control signal meeting the data requirement of the preset transmission interface; and transmitting the control signal to a control object by using the preset transmission interface. When the scheme of the application is applied to the docking station based on the type-C interface, the physical power button signals (such as on and off signals or dormant signals) generated by the power button of the docking station can be converted into the control signals according with the data requirements of the type-C interface to realize the effective transmission of the power button signals of the docking station based on the type-C interface, so that the problem that the docking station based on the type-C interface can not effectively transmit the power button signals is solved, and the power button of the docking station can effectively control the state of a computer.
Example two
In this embodiment, a second possible implementation manner of the signal transmission processing method is provided, and referring to a flowchart of a signal transmission processing method shown in fig. 2, in this embodiment, the method may specifically be implemented through the following processes:
s201: detecting and acquiring a first power button signal of the control device in the form of an analog signal; the first power button signal is any one of a starting signal, a shutdown signal or a dormancy signal in an analog signal form;
s202: performing analog-to-digital conversion on the first power button signal to obtain a second power button signal in a digital signal form;
s203: and carrying out format conversion on the second power button signal to obtain a third power button signal which meets the data format requirement of the preset transmission interface.
S204: and transmitting the control signal (i.e., the third power button signal) to a controller built in the control object using the predetermined transmission interface, so that the controller controls the control object based on the control signal.
In this embodiment, the original control signal obtained by detection may be, but is not limited to, a power button signal of the control device, for example, a power button signal such as a power on/off signal or a sleep signal of the docking station detected by a Type-C dock PD IC of the docking station, where the detected signal is specifically an analog signal.
However, the predetermined transmission interface of the control device, such as the type-C interface of the docking station, can only support data transmission in a digital signal form and with a certain data format, and based on this, this embodiment first performs analog-to-digital conversion on the original control signal of the control device, such as detecting and acquiring the first power button signal of the control device, to obtain the second power button signal in a corresponding digital signal form, and then continues to perform corresponding format conversion on the second power button signal in a digital signal form, so as to convert the second power button signal into the data format that can be supported by the predetermined transmission interface of the control device, and obtain the third power button signal that meets the data format requirement of the predetermined transmission interface.
On this basis, the third power button signal can be transmitted to the controller of the corresponding control object through the predetermined transmission interface, so that the controller controls the control object based on the control signal, and the control of the corresponding control object, such as on/off or dormancy, is realized.
Next, the present embodiment specifically uses the docking station based on the type-C interface as an example to exemplarily describe the signal conversion processing and transmission process.
The Type-C interface of the docking station is a standard port of a new generation USB, which can transmit USB signals conforming to the industry standard, and besides, the current Type-C interface can also transmit VDM (developer definition Message) signals from the Type-C dock PD IC of the docking station, specifically, some pins (first pins) provided by the Type-C interface are responsible for transmitting USB signals conforming to the industry standard, and some other pins (second pins) provided by the Type-C interface are responsible for transmitting VDM signals. The Type-C dock PD IC is mainly responsible for signal communication between the Type-C and the docking station, and a VDM signal format for being opened to a technician is predefined, and generally, the VDM signal format only defines a data frame with a coarser granularity, and some positions are reserved in the frame for the technician to customize the required data requirements in the actual application.
Based on this, this embodiment specifically performs function improvement on the existing Type-C dock PD IC, so that it can detect the power button signal of the docking station, and on this basis, sequentially performs analog-to-digital conversion and data format conversion on the detected power button signal such as power on/off or sleep, and converts it into a VDM signal, so that the signal can be effectively transmitted on the Type-C interface of the docking station. The data format of the VDM signal can be specifically predefined by those skilled in the art based on the coarse-grained VDM data framework provided by the Type-C dock PD IC.
And then, power button signals such as a power on/off signal or a sleep signal in a VDM signal form can be transmitted to the notebook computer through the Type-C interface of the docking station, so that the power button of the docking station can perform required state control on control objects such as the notebook computer.
The Type-C interface of the docking station may specifically transmit a power button signal in the form of a VDM signal to a system PD IC of a control object such as a notebook computer, and the system PD IC transmits the power button signal to a system EC (embedded controller) of the notebook computer through an I2C (Inter-Integrated Circuit) bus after receiving the power button signal, and finally, the system EC performs state control such as matched power on, power off, or hibernation on an operating system of the notebook computer based on the power button signal.
The system PD IC and the system EC are both built in a control object such as a notebook computer.
In summary, the solution of this embodiment solves the problem that the docking station based on the type-C interface cannot effectively transmit the power button signal, so that the power button of the docking station can effectively control the state of the computer device such as the notebook computer, such as being turned on, turned off, or put to sleep.
EXAMPLE III
In this embodiment, the method of each of the above embodiments is supplemented, and with reference to a flowchart of a signal transmission processing method shown in fig. 3, in this embodiment, the method may further include the following steps:
s104: judging whether a feedback signal of the control object is received within a preset time;
s105: if not, the process of transmitting the control signal to the control object by using the preset transmission interface is executed circularly, and the process is finished when the preset condition is met.
The present embodiment specifically designs/defines the control object as follows: when the control object successfully receives the control signal from the control device, the control object feeds back an acknowledgement signal to the control device, so that the control device can know whether the control object successfully receives the control signal according to the feedback condition of the acknowledgement signal, and further know whether the transmission of the control signal can realize effective state control on the control object.
On the basis of designing/limiting the control object, after the control device sends a control signal to the control object through a preset transmission interface of the control device, judging whether a feedback signal of the control object is received within a preset time; if a feedback signal from the control object is received, the control signal sent by the control device is successfully received by the control object, so that the control object can be controlled in a required state, and the control process of the control device can be directly ended under the condition.
If the feedback signal from the control object is not received within the predetermined time length, it indicates that the control signal may be lost in the transmission process, which results in that the control object does not successfully receive the signal, and in order to make the control object still perform effective state control under the condition of signal loss and the like as much as possible, for such a case, the process of transmitting (can be cyclically transmitted based on the predetermined time length period) the control signal to the control object by using the predetermined transmission interface of the control device is cyclically executed, so as to ensure that the control object can receive the control signal sent by the control device to the maximum extent until the predetermined condition is met.
The predetermined condition may specifically be that a feedback signal of the control object is received, or the number of execution times of the loop execution reaches a predetermined number of times, or a timeout occurs.
In the docking station application example based on the Type-C interface, when the feedback signal from the system EC of the notebook computer is not received within the predetermined time, the process of sending the control signal to the system EC of the notebook computer through the Type-C interface can be automatically and circularly executed in the Type-C dock PD IC of the docking station without the user physically triggering by operating the power button of the docking station again or multiple times until the confirmation signal fed back by the system EC of the notebook computer is received, or the number of times of circulating execution reaches the predetermined number of times (such as 3 times), or the process is ended when the timeout is over.
In the embodiment, the process of transmitting the control signal to the control object is automatically and circularly executed when the control object does not successfully receive the control signal of the control device, so that the effective state control of the control object can be ensured to a greater extent, and the success probability of the state control of the control object is further improved.

In the docking station based on the type-C interface, a power button signal of the docking station needs to be converted into a control signal which can be supported by the type-C interface.
A transmission module 300, configured to transmit the control signal to a control object by using the predetermined transmission interface.
Finally, the control signal according with the data requirement (predetermined transmission interface) of the control device can be transmitted to the control object by using the predetermined transmission interface of the control device, so that the control device can control the control object based on the predetermined transmission interface. For the docking station based on the type-C interface, the type-C interface can perform corresponding signal conversion processing on the power button signal of the docking station, so that the type-C interface based on the docking station can perform effective transmission of the power button signal (converted on/off or sleep signal) to the control object such as the notebook computer, and the like, and further the docking station can perform state control such as on/off or sleep on the computer equipment such as the notebook computer and the like at the power button thereof based on the type-C interface.
According to the scheme, the signal transmission processing device provided by the application can convert physical power button signals (such as on, off signals or sleep signals) generated by a power button of the docking station into control signals meeting the data requirements of the type-C interface when the device is applied to the docking station based on the type-C interface, so that the power button signals of the docking station can be effectively transmitted based on the type-C interface.

On the basis of designing/limiting the control object, after the control device sends a control signal to the control object through a preset transmission interface of the control device, judging whether a feedback signal of the control object is received within a preset time; if a feedback signal from the control object is received, the control signal sent by the control device is successfully received by the control object, so that the control object can be controlled in a required state, and the control process of the control device can be directly ended under the condition.
If the feedback signal from the control object is not received within the predetermined time length, it indicates that the control signal may be lost in the transmission process, which results in that the control object does not successfully receive the signal, and in order to make the control object still perform effective state control under the condition of signal loss and the like as much as possible, for such a case, the process of transmitting (can be cyclically transmitted based on the predetermined time length period) the control signal to the control object by using the predetermined transmission interface of the control device is cyclically executed, so as to ensure that the control object can receive the control signal sent by the control device to the maximum extent until the predetermined condition is met.
The predetermined condition may specifically be that a feedback signal of the control object is received, or the number of execution times of the loop execution reaches a predetermined number of times, or a timeout occurs.
In the docking station application example based on the Type-C interface, when the feedback signal from the system EC of the notebook computer is not received within the predetermined time period, the process of sending the control signal to the system EC of the notebook computer through the Type-C interface can be automatically and circularly executed in the Type-C dock PD IC of the docking station without the user physically triggering by operating the power button of the docking station again or multiple times until the confirmation signal of the feedback of the system EC of the notebook computer is received, or the number of times of circulating execution reaches the predetermined number of times (such as 3 times), or the process is ended when the timeout is over.
In the embodiment, the process of transmitting the control signal to the control object is automatically and circularly executed when the control object does not successfully receive the control signal of the control device, so that the effective state control of the control object can be ensured to a greater extent, and the success probability of the state control of the control object is further improved.
