In a terminal device conforming to the Open Pluggable Specification (OPS), the terminal device generally includes a television module and an OPS computer module conforming to the OPS Specification, wherein the television module is used for implementing a television function, and the OPS computer module is used for implementing a computer function. The terminal device with the television function and the computer function is also called a touch control all-in-one machine. The touch control all-in-one machine is widely applied to occasions such as intelligent teaching and teleconferencing, and has the requirements of converting paper file scanning into an electronic file for on-site display, recording display content of the all-in-one machine and the like in some scenes, however, the functional requirements exceed the functional range of the touch control all-in-one machine.
In order to meet the functional requirements of different scenes, an external Multimedia Interface, such as an HDMI (High Definition Multimedia Interface), is generally configured on a touch all-in-one machine at present. External equipment (such as recorded broadcast computer, high appearance of clapping etc.) pegs graft on the multimedia interface of touch-control all-in-one through the multimedia signal line, and above-mentioned external equipment alright like this with regard to as the main display ware with the touch-control all-in-one and carry out the information display in the external equipment, and then realize the function expansion of touch-control all-in-one. Fig. 1 is a schematic structural diagram of a touch control all-in-one machine connected with an external device. As shown in fig. 1, the all-in-one machine includes an OPS computer module 1, a television module 2 connected to the OPS computer module 1, a display 3 connected to the television module 2, and a touch frame 4 disposed around a screen of the display 3, wherein the touch frame 4 is connected to the MCU of the OPS computer module 1 and the MCU of the television module 2 through USB interfaces, respectively. Further, the television module 2 is also connected to one or more external devices 5 through its HDMI interface. Different functional requirements can be realized by selecting the OPS computer module 1, the television module 2 or one of the external devices 5 as a working signal source by using a signal selection unit (not shown in the figure) in the all-in-one machine. For example, when the external device 5 is selected as a working signal source, the external device 5 transmits a display signal to the television module 2, the television module 2 performs signal processing on the received video signal, and then transmits the processed video signal to a TCON (time control register) board in the display 3, and the TCON board decodes the processed video signal and then drives liquid crystal molecules in the display 3 to display an image, thereby finally displaying information in the external device 5 on the display 3.
However, in the touch-control all-in-one machine shown in fig. 1, since the touch-control frame 4 is not connected to the MCU of the external device 5, when the touch-control all-in-one machine uses the external device 5 as its working signal source, the external device 5 can only display and transmit signals on the all-in-one machine, but cannot receive touch-control operation information from the touch-control frame 4 on the screen of the display 3 related to the user. If a user needs to operate the display content of the external device 5, the user needs to operate the external device 5 through an input device (such as a mouse, a keyboard, etc.) arranged on the external device 5, and in a real scene, the external device 5 may be far away from the touch control all-in-one machine, so that the user in front of the touch control all-in-one machine is very inconvenient to operate the external device 5.

Fig. 2 is a schematic diagram of a basic structure of a touch all-in-one machine according to a first embodiment of the present disclosure. As shown in fig. 2, the touch control all-in-one machine is provided with a touch control selection unit 11 and a touch control switch 6. In the touch all-in-one machine, the MCU of the television module is used as the main MCU of the all-in-one machine, so the touch selection unit 11 is disposed in the television MCU of the touch all-in-one machine in the embodiments of the present invention.
The specific connection relationship between the touch selection unit 11 and the touch switch 6 and the modules and the external devices in the touch all-in-one machine is as follows: the MCU of the first external device 51 is connected to the third data output port D of the touch switch 6 via a USB cable3The MCU of the second external device 52 is connected with the Nth data output port D of the touch switch 6 through a USB lineNThe MCU of the OPS computer module 2 is connected with the second data output port D of the touch switch 6 through a USB line2The MCU of the television module 1 is connected with the first data output port D of the touch switch 6 through a USB cable1And (4) connecting. The data input port Y of the touch switch 6 is connected to the data output port of the touch frame 4, and the control input port of the touch switch 6 is connected to the data output port of the touch selection unit 11. The data input end of the touch selection unit 11 is further connected to a signal selection unit (not shown in the figure, which may also be disposed in the MCU of the television module) in the touch all-in-one machine.
It should be noted that, in order to implement unified control on touch switching of the external device, the OPS computer module and the television module and reduce occupation of memory resources, the OPS computer module and the television module are also connected to the touch switch. The embodiment of the present invention is described by taking two external devices as an example, and in the specific implementation, one or more external devices may be used.
In addition, when the integrated machine is designed, the first data output port D of the touch switch 6 can be used1And a second data output port D2The MCU is designed as a built-in interface and is respectively connected with the OPS computer module and the television module; the rest interfaces are designed as external interfaces for connecting external equipment.
Further, the touch selection unit 11 is configured to: receiving from a touchThe method comprises the steps of obtaining working signal source information of a signal selection unit in the all-in-one machine, and generating a corresponding first touch selection signal according to information of an output port used by an external device connected with a touch switch as a working signal source when the external device is determined to be used as the working signal source of the touch all-in-one machine according to the working signal source information, wherein the first touch selection signal is composed of a corresponding number of first touch selection sub-signals according to the number of the external devices connected with the touch all-in-one machine. In addition, since the touch selection unit 11 is further configured to control the touch operations of the OPS computer module and the television module, the touch selection unit 11 of the embodiment of the present invention is further configured to connect information of an output port used by the OPS computer module (i.e. the second data output port D) according to the touch switch when determining that the OPS computer module is used as the work signal source of the touch all-in-one machine according to the work signal source information2) Generating a corresponding second touch selection signal; when the television module is determined to be used as the working signal source of the touch control all-in-one machine according to the working signal source information, the information of the output port used by the television module (namely the first data output port D) is connected according to the touch control switch1) And generating a corresponding third touch selection signal.
And the touch switch 6 is configured to establish a data path connecting the input port and the corresponding output port of the touch frame in the touch switch according to the touch selection signal, and send the touch signal from the touch frame to one of an external device, an OPS computer module or a television module serving as a working signal source through the data path.
By using the touch control all-in-one machine, assuming that the all-in-one machine is in an external signal source channel mode and selects the first external signal source as its working signal source, the touch control selection unit 11 takes the port of the touch control switch 6 connected to the first external device 51 as the third data output port D3Generates a first touch selection sub-signal (e.g. signal 01), and the touch switch 6 establishes a data input port Y and a third data output port D according to the first touch selection sub-signal3Data path of connection, such as from touchThe touch signal of the control frame 4 can be sent to the first external device 51 through the data path, thereby realizing touch control of the first external device 51.
Further, it is assumed that when the integrated machine is switched from the external signal source channel mode to the television channel mode, the touch selection unit 11 receives information that the operating signal source of the signal selection unit in the integrated machine is the television module, and then the touch selection unit 11 outputs a first data output port D of the touch switch 6 connected to the television module 1 according to the information that the operating signal source is the television module1Generates a third touch selection signal (e.g., signal 00), and the touch switch 6 establishes its output port Y and first data output port D according to the third touch selection signal1The connected data path and the touch signal from the touch frame 4 can be sent to the television module 1 through the data path, so that the touch control right is switched from the first external device 51 to the television module 1.
According to the technical scheme, the touch control all-in-one machine provided by the embodiment of the invention can send the touch control signal from the touch control frame to the working signal source according to the working signal source currently used by the touch control all-in-one machine through the matching work of the touch control selection unit and the touch control switch, so that the touch control operation of the touch control frame on the working signal source on the touch control all-in-one machine is convenient for the user to operate. The touch control object can be switched while the working signal source of the touch all-in-one machine is switched and displayed among different signal sources, so that a user does not need to operate external equipment through input equipment (such as a mouse, a keyboard and the like) arranged on the external equipment any more, and the user experience is greatly improved.
However, as a display device for public use, an external device connected to the touch-control integrated machine may change, and a connection correspondence between the external device and a data output port of the touch-control switch may also be changed, so that the touch-control integrated machine cannot correctly determine a correspondence between the external device and the data output port of the touch-control switch.
In order to solve the above problem, the touch all-in-one machine in the embodiments of the present invention is further provided with a touch port setting unit, where the touch port setting unit is configured to obtain output port information, which is input by a user and used by the touch switch to connect to each external device, and send the output port information to the touch selection unit.
By using the touch port setting unit, after the user connects the external device, the corresponding relation between the external device and the data output port of the touch switch can be set on the display screen of the touch all-in-one machine according to the device connection relation of the actual scene. Fig. 3 is a schematic view of an application scenario in which a corresponding relationship between a working signal source and a touch switch interface is manually set according to an embodiment of the present invention. As shown in fig. 3, a user selects a "TOUCH interface channel matching" option on a display screen of the all-in-one machine, and then can enter a secondary menu, after selecting a first data output port of the TOUCH switch, enter a tertiary menu, and after entering the tertiary menu, the user can manually input an HDMI1 or select an HDMI1 option on the screen according to an external device connected to the first data output port, for example, a first external device, and the first external device is connected to the all-in-one machine through an HDMI 1; matching of other ports can also be accomplished according to the same principles.
Therefore, by using the touch port setting unit, the corresponding relation between the display channel and the touch switch port can be manually set according to the hardware connection relation of the actual scene, and further, the touch control of any external device is realized.
In the use process of the touch control all-in-one machine, the situation that an external device is not needed may exist, namely, the external device is not connected with the touch control all-in-one machine, and in this state, in order to enable the touch control selection unit to know whether the external device is connected to the touch control all-in-one machine or not, the data processing amount of the touch control selection unit is reduced. In the embodiment of the present invention, the touch switch 6 is connected to each external device of the touch all-in-one machine through an external USB, and the touch selection unit 11 is also connected to the power lines of the external USB; the touch selection unit 11 is further configured to obtain a connection state between the touch all-in-one machine and each external device according to a first detection signal from a power line in each external USB.
That is, after each external device of the touch all-in-one machine is connected to the data output port of the touch switch 6 through the USB cable, the power line in the USB cable sends a first detection signal of 5V to the touch selection unit 11, and the touch selection unit 11 can know that the external device is connected to the touch all-in-one machine according to the first detection signal. On the contrary, if the first detection signal is not received, it is indicated that the external device is not connected with the touch control all-in-one machine. In this way, the touch selection unit 11 can analyze and judge the specific working signal source used by the touch all-in-one machine according to the working signal source information from the signal selection unit and by combining the first detection signal.
Further, in order to prevent the MCU chip of the touch all-in-one machine from being damaged by overcurrent, overvoltage, and static electricity in the USB power line, in this embodiment, a protection module is further disposed between the USB interface of the external device and the touch selection unit 11 (i.e., the MCU chip of the touch all-in-one machine), and specifically, an input end of the protection module is connected to the USB power line, and an output end of the protection module is connected to the touch selection unit 11, and is configured to convert a first detection signal from the USB power line into a preset voltage signal, and send the preset voltage signal to the touch selection unit 11.
In specific implementation, the protection module may adopt a triode isolation protection tube to convert a 5V voltage signal in a power line in the USB into a 3V voltage signal and send the 3V voltage signal to the touch selection unit, or may also cooperate with components such as a diode and a resistor to realize a signal conversion function.
Fig. 4 is a schematic diagram of a basic structure of a touch all-in-one machine according to a second embodiment of the present invention. As shown in fig. 4, the touch control all-in-one machine in the embodiment of the present invention is different from the first embodiment in that three alternative touch control switches, namely a first touch control switch 61, a second touch control switch 62, and a third touch control switch 63, are disposed therein.
The specific connection relationship between the touch switch and the touch selection unit 11, the modules in the touch all-in-one machine, and the external device is as follows: the MCU of the first external device 51 is connected to the first data output port of the first touch switch 61 through a USB cable, the MCU of the second external device 52 is connected to the second data output port of the first touch switch 61 through a USB cable, and the output/input terminal of the first touch switch 61 is connected to the first data output terminal of the second touch switch 62; the MCU of the OPS computer module 2 is connected to the second data output terminal of the second touch switch 62 through a USB cable, and the data input terminal of the second touch switch 62 is connected to the first data output terminal of the third touch switch 63; the MCU of the television module 1 is connected to the second data output terminal of the third touch switch 63 through a USB cable, and the data input terminal of the third touch switch 63 is connected to the touch frame 4. The touch selection unit 11 disposed in the television module 1 is connected to the control terminals of the first touch switch 61, the second touch switch 62, and the third touch switch 63, respectively. In addition, power lines of the USB lines of the first external device 51 and the second external device 52 are respectively connected to the touch selection unit 11.
In the working process of the touch control all-in-one machine, when the elected television module 1 is used as a working signal source, that is, the all-in-one machine is in a television channel mode, at this time, the touch control selection unit 11 sets the I/O5 to be at a high level, that is, sends a high level signal to the control end of the third touch control switch 63, and sets the I/O3 and the I/O4 to be at a low level, so that a path from the data input port of the third touch control switch 63 to the second data port is gated, and at this time, the touch control of the television module 1 can be realized through the touch control frame 4.
When the OPS computer module 2 is selected as a working signal source, that is, the all-in-one machine is in the OPS channel mode, the touch selection unit 11 sets the I/O4 to a high level, and sets the I/O3 and the I/O5 to a low level, so as to gate the path from the data input port of the second touch switch 62 to the second data port and the path from the data input port of the third touch switch 63 to the first data port, and further gate the path between the OPS computer module 2 and the touch frame 4, and at this time, the touch control of the OPS computer module 2 can be realized through the touch frame 4.
Similarly, when the first external device 51 is selected as its operating signal source, the I/O3, the I/O4, and the I/O5 are all set to low level, and when the second external device 52 is selected as its operating signal source, the I/O3 is set to high level, and the I/O4 and the I/O5 are set to low level, thereby respectively implementing touch control on the first external device 51 and the second external device 52. Further, if only one external device is connected, it may be determined whether the first external device 51 or the second external device 52 is connected by detecting the high/low levels of the I/O1 and the I/O2 in the USB power source, so as to control the I/O3 to be low or high.
By using the above-mentioned serial connection manner of the two-out-of-one touch switch, each I/O interface of the touch selection unit 11 only needs to control and output a high level or low level signal, so that the complexity of the signal is reduced, and the error rate of the signal can be reduced.
In the above embodiment, although the touch port setting unit is used, although the matching setting of the external device and the touch switch port can be realized, the touch switch port needs to be manually set, and the touch switch may not be convenient in actual use. Fig. 5 is a schematic diagram of a basic structure of a touch all-in-one machine provided in the third embodiment of the present invention.
As shown in fig. 5, the difference between the all-in-one machine in this embodiment and the above all-in-one machine is that a USB switch is further disposed between the touch selection unit and the external device in the all-in-one machine in this embodiment. It should be noted that the structure diagram in this embodiment is a simplified diagram of the first and second embodiments, and this embodiment only shows an I/O interface in the touch selection unit for connecting with a USB power line of an external device.
Specifically, the USB switch is connected to a hot plug detection line in the external HDMI, a touch selection unit, and a power line in the external USB, respectively, where the external HDMI is an interface for connecting the touch-control integrated machine and each external device. The USB switch is used for selecting whether to forward a first detection signal from a power line in an external USB to the touch selection unit or not according to a second detection signal from the hot plug detection line.
Assuming that the first external device 51 and the second external device 52 are respectively connected to HDMI1 and HDMI2 of the all-in-one machine, the USB for receiving the TOUCH signal is respectively connected to external data output terminals TOUCH1 and TOUCH2 of the TOUCH switch, when the all-in-one machine switches the current channel to HDMI1, that is, the first external device 51 is used as a working signal source, at this time, the MCU of the television module 1 controls the hot plug1 (hot plug detection line) in the HDMI1 for the first external device 51 to be pulled to high level, after receiving the high level signal, the first external device 51 sends an audio/video signal to the all-in-one machine, and at the same time, the USB switch corresponding to the first external device 51 also receives the high level signal, thereby turning on the TOUCH1 connected to +5V output. Meanwhile, the MCU of the tv module 1 will control the hot plug2 in the HDMI2 for the second external device 52 to pull low level, and the second external device 52 will stop providing the audio/video signal of the all-in-one machine after receiving the low level, and meanwhile, the USB switch corresponding to the second external device 52 will also be physically connected to TOUCH1 connected to the all-in-one machine for +5V output.
By using the USB switch structure, only the external device used as the working signal source can send the first detection signal to the TOUCH selection unit, so that the TOUCH selection unit can detect the states of TOUCH1 and TOUCH2 according to I/O1 and I/O2 without manual matching, obtain the corresponding relation between the external device currently used as the working signal source and the data output port of the TOUCH switch, and send the TOUCH control signal to the TOUCH switch, thereby realizing the communication connection between the TOUCH frame and the external device used as the working signal source.
Further, the USB switch may be disposed in a switching module (e.g., the first switching module 71 and the second switching module 72 in fig. 5), the HDMI input and output ports of the switching module are respectively connected to the HDMI ports of the external device and the all-in-one machine, the USB input and output ports are respectively connected to the USB port of the external device and the data output port of the touch switch in the all-in-one machine, the USB switch control port is connected to the hot plug of the HDMI line in the switching module, and the data input and output ports correspond to the USB input and output ports of the switching module respectively. Of course, the USB switch may be disposed in an external device.
By utilizing the touch all-in-one machine, the embodiment of the invention also provides a touch control method of the touch all-in-one machine. Fig. 6 is a flowchart illustrating a touch control method of a touch all-in-one machine according to an embodiment of the present invention. As shown in fig. 6, the method specifically includes the following steps:
s110: the touch selection unit acquires the working signal source information of the touch all-in-one machine.
Specifically, the working signal source information from the signal selection unit in the touch all-in-one machine can be acquired.
S120: and when the touch selection unit determines that the working signal source of the touch all-in-one machine is the external equipment according to the working signal source information, the touch selection unit acquires information of an output port used by a touch switch connected with the external equipment serving as the working signal source.
The method for acquiring the information of the output port used by the external device connected with the touch switch as the working signal source by the touch selection unit may include the following steps:
1) a touch selection unit in the touch all-in-one machine acquires output port information used for connecting a touch switch input by a user at a touch port setting unit of the touch all-in-one machine with each external device;
2) and the touch control selection unit obtains the information of the output port used by the external equipment connected with the touch control switch as the working signal source according to the information of the output port used by the connection of the touch control switch and the external equipment.
In addition, in order to more conveniently acquire information of an output port used by external equipment serving as a working signal source, the embodiment of the present invention uses the all-in-one machine provided in the third embodiment, and further provides the following method:
a) the touch control selection unit obtains a first detection signal of an external USB power line forwarded by the USB switch, and the external USB power line is a power line in a USB used for connecting the touch control switch and the external equipment.
When the USB switch receives the second detection signal in the hot plug, the first detection signal of the USB power line is sent to the touch selection unit.
b) And the touch selection unit takes the output port of the touch switch connected with the USB switch for forwarding the first detection signal as the output port for connecting the touch switch and the external equipment as the working signal source.
Further, with the steps a) and b), the touch control steps S110 and S120 may be optimized, specifically including:
firstly, a touch control selection unit judges whether a first detection signal of an external USB power line forwarded by a USB switch is received; then, if the first detection signal is received, the touch selection unit uses the output port of the touch switch connected to the USB switch that forwards the first detection signal as the output port for connecting the touch switch and the external device serving as the working signal source, and continues to execute step S130. On the contrary, if the first detection signal is not received, the touch selection unit determines whether the working signal source is the television module or the OPS computer module, for example, the touch selection unit determines whether the current working signal source is the television module according to the working signal source information from the signal selection unit in the touch all-in-one machine, if the current working signal source is the television module, a touch control signal for switching the touch right to the television module is sent to the touch switch, and if the current working signal source is not the television module, a touch control signal for switching the touch right to the OPS computer module is sent to the touch switch.
S130: and the touch control selection unit sends a touch control signal which enables a data path to be established between the input port and the output port of the touch control frame connected in the touch control switch to the touch control switch according to the information of the output port.
Then, the touch switch establishes a data path between the input port connected with the touch frame and the output port used by the external device serving as the working signal source according to the received control signal, so that the touch signal from the touch frame is sent to the external device serving as the working signal source through the data path, and the touch operation of the external device through the touch frame on the touch all-in-one machine is further realized.
Further, in step S120, when the touch selection unit determines that the working signal source of the touch all-in-one machine is the external device according to the working signal source information, it is possible that the touch selection unit may determine the information of the working signal source used by the touch all-in-one machine after sequentially performing the steps of determining whether the touch all-in-one machine uses the television module, the OPS computer module, the first external device, the second external device, and the like according to the working signal source information. In practical application, the integrated machine may not be connected to an external device, so that some steps in the process of determining the working signal source may not necessarily exist.
To solve the problem, the present embodiment further provides another touch control method, that is, before step S110, the method further includes the following steps:
s210: the touch control selection unit judges whether a first detection signal from a power line in an external USB is received, wherein the external USB is used for connecting the touch control switch and an external device.
For example, by using the all-in-one machine in the above embodiment, the I/O1 and the I/O2 are used as detection pins for detecting whether the external device is accessed, when both the I/O1 and the I/O2 are at low level, it indicates that no external device is accessed, and when one of the I/O1 and the I/O2 is at high level, it indicates that a preset level signal from a power line in the external USB is received, and an external device is accessed.
If the preset level signal is received, the process proceeds to step S110. On the contrary, if the preset level signal is not received, the television module or the computer module is used as the signal source of the touch all-in-one machine currently, so that the corresponding touch control unit in the all-in-one machine can quickly confirm the current signal source of the touch all-in-one machine through once comparison and analysis, and further, the switching control of the touch right can be quickly realized.
By the touch control method, seamless switching can be met while switching display among different signal sources, and further touch operation on equipment serving as a working signal source can be achieved by using the touch frame around the screen of the all-in-one machine, so that user experience is improved.
