DETAILED DESCRIPTION

[0049] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The commonly used power supply and communication method for display terminals is to control power supply and communication separately. On the one hand, when supplying power and communicating to the entire architecture of a larger display terminal (40-100 inches), power is usually obtained from the city power grid. The 110V-230V AC power obtained from the city power grid is rectified into high-voltage DC power through an AC-DC converter, and then the high-voltage DC power is reduced to low-voltage DC power through a DC step-down circuit to power the backlight drive system and control system of the display terminal. After power supply, the Ethernet port and WIFI (Wireless Fidelity) module in the control system communicate with the Internet. At this time, power supply and communication are separate. On the other hand, when powering and communicating the entire architecture of consumer-grade small display devices (less than 32 inches), an external adapter is usually used to obtain power from the city power grid. After the adapter is connected to the city power grid, the city power is converted into DC low voltage through a DC step-down circuit and directly transmitted to the display terminal. After the display terminal obtains DC low voltage power from the adapter, it powers the backlight drive system and control system of the display terminal, and after power supply, it communicates with the Internet through the Ethernet port and WIFI module in the control system. At this time, no matter which of the above methods is used, power supply and communication are separate.

[0052] Therefore, based on the inadequacy of the above display terminal control scheme, a control method for the display terminal of the present application is proposed. The solution of the embodiment of the present application is to obtain the circuit working state information of the network port connection circuit, and generate a terminal control instruction for controlling at least one of the network port connection circuit, the interface circuit and the communication module based on the circuit working state information, that is, at this time, the power supply and communication can be selected based on the network port connection circuit for power supply and communication, the interface circuit for backup power supply and the communication module for backup communication, and the phenomenon that the communication-related circuit and the power supply-related circuit need to be controlled separately and there is no backup control occurs, thereby improving the functionality of the power supply and communication of the display terminal.

[0053] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a device capable of realizing the above functions, a control device of a display terminal, etc. The following takes the control device of a display terminal (which may be a display terminal in this embodiment) as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the embodiment of the present application provides a control method for a display terminal, referring to Figure 1 , Figure 1 It is a flowchart diagram of the first embodiment of the control method of the display terminal of the present application.

[0055] Reference Figure 1The present application provides a control method for a display terminal. In a first embodiment of the control method for a display terminal, the control method for a display terminal is applied to a display terminal, the display terminal includes a network port connection circuit for power supply and communication, an interface circuit for backup power supply, and a communication module for backup communication. The control method for the display terminal includes:

[0056] Step S10, obtaining circuit working state information of the network port connection circuit, and determining the terminal control instruction according to the circuit working state information;

[0057] For example, Figure 2 This is a schematic diagram of the network port connection circuit of the display terminal of the present application. The network cable is directly connected through the Ethernet port 152. The network cable is based on the network port connection circuit 110 of the display terminal set by the display terminal 100 to realize the power supply and communication of the display terminal 100 at the same time. At the same time, Type-c153 is set in the control system for power supply backup, and a WIFI module is set for communication backup. Further reference Figure 3 , Figure 3 This is another schematic diagram of the network port connection circuit of the display terminal of the present application. The network port connection circuit 110 of the display terminal includes a network port transformer unit 10 and a network port power supply unit 20, so as to realize communication signal transmission through the network port transformer unit 10 and realize power transmission through the network port power supply unit 20. At the same time, a circuit schematic diagram of the network port transformer unit 10 and the network port power supply unit 20 (one connection circuit schematic) is also proposed to illustrate the network port transformer unit 10 and the network port power supply unit 20.

[0058] In one embodiment, referring to Figure 4 , Figure 4The network port transformer unit in the network port connection circuit of the display terminal of the present application is a connection diagram. The network port transformer unit 10 includes a transformer chip T1. At this time, the external input network port J1 and the internal input network port J2 each include twelve network port terminals (the internal terminals can be directly connected by PCB wiring, and the legend is only for the convenience of function definition), and there are only eight gateway terminals for data or power transmission. At this time, every two network port terminals are connected to a transformer sub-unit T11 in the transformer chip T1, and corresponding connections are made according to the corresponding relationship between the network port terminals between the external input network port J1 and the internal input network port J2. For example, as described by the above transformer sub-unit T11, each transformer sub-unit T11 includes an input positive electrode Terminal MX+, input negative terminal MX-, output positive terminal TD+, output negative terminal TD-, input intermediate terminal MCT and output intermediate terminal TCT, and the above connection relationship exists, thereby realizing the transmission of the communication signal of the input positive terminal MX+ and the input negative terminal MX- to the output positive terminal TD+ and the output negative terminal TD-; at the same time, the electric energy of the input positive terminal MX+ and the input negative terminal MX- is transmitted to the network port power supply unit 10 through the input intermediate terminal MCT, and then output to the power supply interface 130 through the network port power supply unit 10, so as to realize the communication and power supply of the display terminal 100, wherein PR12 refers to the data pair from the first external network port terminal r1 and the second external network port terminal r2 through the tap of the transformer.

[0059] In one embodiment, referring to Figure 5 , Figure 5This is a connection diagram of a network port power supply unit in the network port connection circuit of the display terminal of the present application. The network port power supply unit 20 connected to the input intermediate terminal MCT includes two rectifier chips 21. Because the input intermediate terminal MCT outputs two pairs of signals, two rectifier chips 21 are required for processing. Each rectifier chip 21 includes two rectifier circuits, and each rectifier circuit is connected to a signal of the input intermediate terminal MCT. The rectifier circuit includes two rectifier circuits 211. The rectifier circuit 211 is composed of a first switch tube Q1, a first capacitor C1, a first resistor R1, a first transistor Q2, a diode subcircuit 2111, a second capacitor C2 and a second resistor R2, and the connection relationship is the above connection relationship. At the same time, based on the different outputs of the first switch tube Q1 (the first end of the first switch tube Q1 is connected to the positive voltage input terminal VDD or to the negative voltage input terminal VSS), the connection relationship inside the diode subcircuit 2111 is different. For example, when the first end of the first switch tube Q1 is connected to the positive voltage input terminal VDD, the cathode of the first diode D1 serves as the first end of the diode subcircuit 2111, and the cathode of the second diode D2 serves as the second end of the diode subcircuit 2111; when the first end of the first switch tube Q1 is connected to the negative voltage input terminal VSS, the anode of the first diode D1 serves as the first end of the diode subcircuit 2111, and the anode of the second diode D2 serves as the second end of the diode subcircuit 2111. At this time, rectified electric energy can be provided to the display terminal, which is not described herein. Figure 5 All connections are described (such as the output control subunit 22 connected to the rectifier chip 21 to ensure normal output, and the output control subunit 22 connected to the rectifier chip 21). Further, refer to Figure 6 , Figure 6This is another connection diagram of the network port power supply unit in the network port connection circuit of the display terminal of the present application. The network port power supply unit 10 also includes a power supply interface chip U1. The power supply interface chip U1 can adopt the TPS2373 solution of TI. The TPS2373 chip is used to process and output the positive voltage output terminal and the negative voltage output terminal to the DC converter BT. BT is an isolation transformer with DC voltage conversion and isolation functions. U2 and the BT isolation transformer constitute the DC converter function. The DC converter BT can be a commonly used conversion chip. It only needs to realize the DC conversion function. It can directly output voltage to the power supply interface 130 based on the DC converter BT to power the display terminal 100. At the same time, the network port power supply unit 10 also includes a low voltage control chip U2, which can control the voltage output to a low voltage to achieve output of different voltages. At this time, the network port connection circuit 110 based on the display terminal is normally connected to the network cable (i.e., the external input network port J1), and the Type-c153 (which can be powered by the Type-c cable) is also powered normally, and the control method of the display terminal of this application is executed (at this time, the external input network port J1 and Type-c153 input are set to be normal and the WIFI module 151 is normal). The above-described situation is defined as a normal state, and the following description is based on the normal state.

[0060] In this embodiment, the control method of the display terminal is applied to the display terminal, which can be a television, etc., and includes a network port connection circuit for power supply and communication (i.e., the network port connection circuit 110 of the display terminal), an interface circuit for backup power supply (which can be Type-c153, or other power supply interfaces) and a communication module for backup communication (which can be a WIFI module 151, or other communication interfaces). Generally, the priority network port connection circuit realizes power supply and communication functions at the same time, and the interface circuit for backup power supply and the communication module for backup communication are used for backup power supply and communication. By obtaining the circuit working status information of the network port connection circuit, the terminal control instruction can be determined based on the circuit working status information, that is, by determining whether there is an abnormality in the circuit working status information (communication abnormality or power supply abnormality), and then judging whether there is an abnormality to control the interface circuit for backup power supply and the communication module for backup communication to work, or continuously control the network port connection circuit to work. Among them, the circuit working status information refers to the working status of the network port connection circuit, such as network status, power supply status, etc. The terminal control instruction refers to the instruction for power supply and communication control of the terminal, such as selecting the network port connection circuit for power supply and communication, selecting the interface circuit for power supply, and selecting the communication module for communication, so as to avoid the phenomenon that communication-related circuits and power supply-related circuits need to be controlled separately without backup control, thereby improving the power supply and communication functionality of the display terminal.

[0061] Step S20, controlling at least one of the network port connection circuit, the interface circuit and the communication module according to the terminal control instruction.

[0062] In this embodiment, after obtaining the terminal control instruction, the network port connection circuit will be controlled to perform power supply and communication, the network port connection circuit will be controlled to perform power supply and communication with the communication module, the network port connection circuit will be controlled to perform communication and the interface circuit will be controlled to perform power supply, and the interface circuit will be controlled to perform power supply and communication with the communication module based on the terminal control instruction to ensure the normal operation of the display terminal while improving the power supply and communication functionality of the display terminal.

[0063] In the present embodiment, a control method for a display terminal is provided, which is applied to the display terminal. The display terminal includes a network port connection circuit for power supply and communication, an interface circuit for backup power supply, and a communication module for backup communication. The circuit working state information of the network port connection circuit is obtained, and a terminal control instruction is determined according to the circuit working state information; at least one of the network port connection circuit, the interface circuit, and the communication module is controlled according to the terminal control instruction. The control method for the display terminal obtains the circuit working state information of the network port connection circuit to generate a terminal control instruction for controlling at least one of the network port connection circuit, the interface circuit, and the communication module based on the circuit working state information. That is, at this time, power supply and communication can be selected based on the network port connection circuit for power supply and communication, the interface circuit for backup power supply, and the communication module for backup communication, thereby avoiding the phenomenon that communication-related circuits and power supply-related circuits need to be controlled separately and there is no backup control, thereby improving the functionality of power supply and communication of the display terminal.

[0064] Further, based on the above-mentioned first embodiment of the present application, a second embodiment of the control method of the display terminal of the present application is proposed. In this embodiment, in the above-mentioned step S10, the circuit working state information includes a real-time output voltage value in the network port connection circuit, and the step of determining the terminal control instruction according to the circuit working state information includes:

[0065] Step S11, detecting whether the real-time output voltage value is less than a preset minimum voltage value;

[0066] Step S12, if the real-time output voltage value is less than the preset minimum voltage value, determining the preset power supply switching instruction as the terminal control instruction;

[0067] Step S13: If the real-time output voltage value is greater than or equal to the preset minimum voltage value, a preset power supply continuity instruction is determined as the terminal control instruction.

[0068] In this embodiment, the circuit working status information includes the real-time output voltage value in the network port connection circuit, that is, the voltage of the power supply output port can be collected as the real-time output voltage value through a voltage or current sensor, so as to determine the control instruction based on the real-time output voltage value. Because when Type-c153 is powered, the voltage will be lower due to device limitations (there are some problems with poor display effects), so it will be judged whether the real-time output voltage value of the network port connection circuit will be less than the preset minimum voltage value of Type-c153. Then, when it is less than the preset minimum voltage value, Type-c153 can be used directly for power supply, and energy-saving measures for the whole machine power consumption can be taken; otherwise, the network port connection circuit can continue to be used for power supply. Among them, the preset minimum voltage value is a voltage value set by the power supply voltage of Type-c153, and can also be directly set to 0. That is, if the real-time output voltage value is less than the preset minimum voltage value, that is, the network port connection circuit cannot supply power normally, then the preset power supply switching instruction is determined as the terminal control instruction, and the preset power supply switching instruction refers to the instruction to switch to the interface circuit for power supply; if the real-time output voltage value is greater than or equal to the preset minimum voltage value, that is, the network port connection circuit can supply power normally, then the preset power supply continuation instruction is determined as the terminal control instruction, and the preset power supply continuation instruction refers to the instruction to continue to use the network port connection circuit for power supply, so that the display terminal can be switched to power supply in time based on the judgment of the output voltage to ensure the normal operation of the display terminal, while improving the intelligence of the display terminal power supply. It is worth noting that the entire process can also determine the relationship between other circuit parameters such as the output current value.

[0069] In one embodiment, if the real-time output voltage value is less than the preset minimum voltage value, after the step of determining the preset power supply switching instruction as the terminal control instruction, the method further includes:

[0070] Step S121, obtaining a communication feedback value fed back by the network port connection circuit under the control of a preset communication start instruction, and detecting whether the communication feedback value matches a preset communication interruption value;

[0071] Step S122: if the communication feedback value matches the preset communication interruption value, the terminal control instruction is updated, wherein the updated terminal control instruction includes a preset power supply switching instruction and a preset communication switching instruction.

[0072] In this embodiment, after judging the power supply, the communication can also be judged, because the communication will not exist or run continuously like the power supply. Therefore, it is necessary to detect the communication after judging the power supply, and the detection can be selectively executed after determining the preset power supply continuous instruction as the terminal control instruction, but after determining the preset power supply switching instruction as the terminal control instruction, step S121-step S122 must be executed. It is mainly through obtaining the communication feedback value fed back by the network port connection circuit under the control of the preset communication start instruction, and then detecting the communication feedback value, wherein the communication start instruction refers to the instruction to start the communication function of the network port connection circuit to communicate, such as obtaining the network time, etc. The communication feedback value refers to the communication status based on the feedback of the communication start instruction. If the network time can be obtained normally, the communication feedback value is 1, otherwise, if it is not normal or the network time cannot be obtained, the communication feedback value is 0. At this time, it will detect whether the communication feedback value matches the preset communication interruption value (match means that the two values ​​are the same). If the defined preset communication interruption value is 0, that is, when the communication feedback value is 0, it can be determined that the network port connection circuit communication is abnormal at this time. Then, when the communication feedback value matches the preset communication interruption value, the terminal control instruction will be updated. Among them, the updated terminal control instruction includes the preset power supply switching instruction and the preset communication switching instruction, that is, it is necessary to switch the power supply and the communication mode at the same time. The preset communication switching instruction refers to the instruction to switch to the communication module communication to ensure normal communication and power supply of the display terminal.

[0073] Further, based on the first embodiment and / or the second embodiment of the present application, a third embodiment of the control method of the display terminal of the present application is proposed. In this embodiment, the circuit working state information includes a communication feedback value fed back each time the network port is connected to the circuit for communication. The step of determining the terminal control instruction according to the circuit working state information includes:

[0074] Step S14, detecting whether the communication feedback value matches the preset communication interruption value;

[0075] Step S15, if the communication feedback value matches the preset communication interruption value, determining the preset communication switching instruction as the terminal control instruction;

[0076] Step S16: If the communication feedback value does not match the preset communication interruption value, a preset communication continuation instruction is determined as the terminal control instruction.

[0077] In this embodiment, in addition to detecting the output voltage in real time, the communication state is also detected at each communication, by obtaining the communication feedback value fed back at each communication, and then detecting whether the communication feedback value matches the preset communication interruption value, and when the communication feedback value matches the preset communication interruption value, the preset communication switching instruction is determined as the terminal control instruction, otherwise, when the communication feedback value does not match the preset communication interruption value, the preset communication continuation instruction is determined as the terminal control instruction, and the communication switching control can be performed based on each communication result to ensure the accuracy of the communication. It is worth noting that at this time, the communication feedback information fed back at each communication can be obtained, and then the network port connection circuit and the communication module are controlled based on the communication feedback information. The communication feedback information refers to the display information of the display terminal on the communication effect, such as busy communication, and then the network port connection circuit and the communication module can be controlled to work at the same time, and one of them is selected as the input communication channel and the other as the output communication channel to reduce the efficiency of the interactive data of the display terminal. At the same time, different communication methods can also be selected according to the actual situation, such as selecting the network port connection circuit in certain scenarios based on the advantages of network port communication, and using the communication module for communication in other scenarios to greatly improve the communication effect.

[0078] In one embodiment, the step of controlling at least one of the network port connection circuit, the interface circuit, and the communication module according to the terminal control instruction includes at least one of the following:

[0079] Step S21, when the terminal control instruction is a preset power supply switching instruction, the control interface circuit supplies power to the display terminal;

[0080] Step S22, when the terminal control instruction is a preset communication switching instruction, controlling the communication module to communicate with the display terminal;

[0081] Step S23, when the terminal control instruction is a preset power supply continuation instruction, controlling the network port connection circuit to supply power to the display terminal;

[0082] Step S24, when the terminal control instruction is a preset communication continuation instruction, controlling the network port connection circuit to communicate with the display terminal.

[0083] In this embodiment, after the terminal control instruction is obtained, at least one of the network port connection circuit, the interface circuit and the communication module will be controlled based on the terminal control instruction, and the control process may be: when the terminal control instruction is a preset power switching instruction, the interface circuit is controlled to power the display terminal; when the terminal control instruction is a preset communication switching instruction, the communication module is controlled to communicate with the display terminal; when the terminal control instruction is a preset power continuation instruction, the network port connection circuit is controlled to power the display terminal; when the terminal control instruction is a preset communication continuation instruction, the network port connection circuit is controlled to communicate with the display terminal. It may also be a composition between the above different communication and power supply modes, which will not be explained one by one here, and then through the intelligent switching between the above communication and power supply modes, the power supply and communication functionality of the display terminal are improved. Further, refer to Figure 7 , Figure 7 This is a module diagram of the first embodiment of the control method of the display terminal of the present application. The network port connection circuit inputs the signal and electric energy into the network transformer 101 (i.e., the transformer chip T1) based on the external input network port 200. At this time, the signal can communicate with the control system 150, and the electric energy is transmitted to the isolation transformer 203 (i.e., the DC converter BT) through the rectifier bridge 201 (i.e., the rectifier chip 21) and the PoE PD interface chip 202 (i.e., the power supply interface chip U1) to give it to the backlight drive system 140, and is transmitted to the control system 150 for power supply via the control power supply circuit 204 (such as a circuit with reduced voltage), so as to complete the power supply and communication functions through the network port connection circuit. At the same time, it can also directly communicate based on the WIFI module 151, and directly complete the power supply through Type-c153 to realize the power supply and communication backup of the display terminal, and then realize the intelligent switching between power supply and communication based on the above display terminal control method to ensure the normal operation of the display terminal.

[0084] Further, based on the first embodiment, the second embodiment and / or the third embodiment of the present application, a fourth embodiment of the control method of the display terminal of the present application is proposed. In this embodiment, the display terminal also includes a voltage collector and a data transmitter connected to the output end of the network port connection circuit, and the step of obtaining the circuit working state information of the network port connection circuit includes at least one of the following:

[0085] Step S101, obtaining a real-time output voltage value collected by a voltage collector as circuit working state information of a network port connection circuit;

[0086] Step S102, obtaining the communication feedback value collected by the data transmitter each time when communicating as the circuit working state information of the network port connection circuit.

[0087] In this embodiment, the display terminal also includes a voltage collector and a data transmitter connected to the output end of the network port connection circuit. The voltage collector can be a commonly used voltage sensor to collect the voltage at the output end of the network port connection circuit to determine whether the network port connection circuit can normally power the display terminal. The data transmitter can be a commonly used data transmitter, that is, to determine whether there is network data transmission during communication to determine whether the network port connection circuit can normally communicate for the display terminal. The real-time output voltage value collected by the voltage collector is used as the circuit working state information of the network port connection circuit, and can be detected in real time, and when the detection is unsuccessful (voltage abnormality), control the detection communication function while switching to other power supply methods. The data transmitter needs to detect only when there is data transmission, and then obtain the communication feedback value collected by the data transmitter each time as the circuit working state information of the network port connection circuit, and when the detection is unsuccessful (communication abnormality), switch to other communication methods to improve the functionality of power supply and communication of the display terminal.

[0088] Further, based on the first embodiment, the second embodiment and / or the third embodiment of the present application, a fourth embodiment of the control method of the display terminal of the present application is proposed. In this embodiment, the network port connection circuit includes a voltage division control chip, and the control method of the display terminal includes:

[0089] Step a, upon receiving the required voltage information, determining a voltage division control instruction in a preset voltage division control table based on the required voltage information;

[0090] Step b: performing voltage division control on the voltage division control chip based on the voltage division control instruction.

[0091] In this embodiment, in addition to supplying power to the display terminal normally, the network port connection circuit also controls the output voltage, because the network port connection circuit includes a voltage division control chip, that is, a low voltage control chip U2. Then, when the required voltage information is received, the voltage division control instruction can be determined in the preset voltage division control table based on the required voltage information, and finally the voltage division control chip can be controlled based on the voltage division control instruction to input the voltage after the voltage division into the display terminal for power supply. Among them, the required voltage information refers to the voltage value required by the user, the preset voltage division control table defines the relationship between the output voltage and the control instruction, and the voltage division control instruction refers to the instruction to control the voltage division control chip to reach the voltage value required by the user. For example, if the user needs 5V voltage, the voltage division control instruction is determined to be 110 in the preset voltage division control table, that is, after the voltage division control instruction 110 is input to the voltage division control chip, the voltage division control chip can output 5V voltage. It is worth noting that the principle of the voltage division control chip can be to control the resistance of the access circuit based on the voltage division control instruction to achieve the voltage division effect, or it can be other voltage division principles, which are not limited here.
