Description

Technical Field

However, this method requires the setting of identification resistors on both the main board and the sub-board, which occupies the resources and wiring space of the main and sub-boards; it also requires additional connection of the digital-to-analog converter, which occupies space and increases costs; it also occupies the board-to-board connection pin (BTB) resources of the main and sub-boards, and the general input and output interface (GPIO) resources of the central processing unit; and if some platforms do not have enough digital-to-analog converters or general input and output ports, additional external switches need to be added, thereby increasing the design cost.

[0033] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0035] At present, the internal circuit structure of terminal products mostly adopts the design of main board plus sub-board, and it is necessary to ensure that sub-boards of different configurations should be connected to their corresponding main boards. However, whether in the product research and development stage or the product production stage, when the product needs to be assembled or disassembled, there will be situations where staff mix up the circuit boards, resulting in adverse consequences such as erroneous test results and product scrapping.

[0036] The embodiment of the present application proposes a terminal device, which distinguishes sub-boards with different configurations by detecting different identification potentials of the sub-board switch unit. Before introducing the terminal device proposed in this solution, the method of distinguishing the sub-board configuration in the prior art is first introduced to make it easier to understand this solution later.

[0037] Currently, identification resistors can be set on the main board and the sub-board, and a digital-to-analog converter can be connected between the mainboard central processor and the sub-board to detect the circuit voltage division to distinguish sub-boards with different configurations.

[0038] For example, Figure 1 The following is a schematic diagram of the structure of a terminal device provided by the prior art. Figure 1 As shown, a terminal device provided by the prior art includes a main board 101 , a sub-board 102 , a central processing unit 103 and an antenna switch 104 .

[0039] The central processing unit 103 is connected to the antenna switch 104; one end of the first identification resistor R1 is connected to the central processing unit 103 and the other end is grounded; one end of the second identification resistor R2 is connected to the power port of the central processing unit 103 and the other end is connected to the first identification resistor R1.

[0040] Among them, the principle of distinguishing the configuration of the sub-board in the prior art is: the sub-board configuration is identified by reading the voltage division of the first identification resistor R1 and the second identification resistor R2 through the analog-to-digital converter in the central processor 103. For example, the first identification resistor R1 and the second identification resistor R2 of the first configuration sub-board use the same resistance resistor, such as 100K; the first identification resistor R1 and the second identification resistor R2 of the second configuration sub-board use the same resistance resistor, such as 200K; therefore, when the main and sub-boards are connected with the correct configuration, the value read by the analog-to-digital converter in the central processor 103 is half of the power port voltage. If the main and sub-boards are not connected with the correct configuration, the value read by the analog-to-digital converter in the central processor 103 is not half of the power port voltage, thereby achieving the distinction between different sub-boards.

[0041] However, the above structure requires setting identification resistors on both the main board and the sub-board, occupying the resources and wiring space of the main and sub-boards; and additional connection digital-to-analog converters are required, which takes up space and increases costs; and the board-to-board connection pin resources of the main and sub-boards are occupied, and the general input and output interface resources of the central processing unit are occupied; and if some platforms have insufficient digital-to-analog converters or general input and output, additional external switches are required, thereby increasing design costs.

[0042] In order to solve the above technical problems, an embodiment of the present application provides a terminal device, and the terminal device provided by the present application will be introduced in detail below.

[0043] For example, Figure 2 A schematic diagram of the structure of a terminal device provided in an embodiment of the present application. Figure 2 As shown, the terminal device provided in the embodiment of the present application includes a first circuit board 201 and a second circuit board 202; wherein, the processing unit 203 is arranged on the first circuit board 201, the switch unit 204 is arranged on the second circuit board 202, and the processing unit 203 is connected to the switch unit 204.

[0044] The principle of identifying differently configured circuit boards within the terminal device provided in the embodiment of the present application is as follows: the switch units 204 of different second circuit boards 202 are configured with different identification potentials, and the processing unit 203 distinguishes the differently configured second circuit boards 202 according to the different identification potentials.

[0045] In the embodiment of the present application, the first circuit board 201 can be used as the main board, and the second circuit board 202 can be used as the sub-board. By detecting the different identification potentials configured in the sub-board switch unit, different sub-boards can be distinguished, so that the main board and the sub-board can be connected according to the correct configuration requirements to avoid the situation where the staff mixes up the circuit boards. In addition, this solution does not require additional digital-to-analog converters and identification resistors, does not need to occupy the resources and wiring space of the main and sub-boards, and saves design costs; the configuration identification method proposed in this solution utilizes the original interface of the terminal device, so it does not need to occupy the main and sub-board board-to-board connection pin resources and the general input and output interface resources of the central processor as in the prior art, and also saves the resources and wiring space of the main and sub-boards.

[0046] In some embodiments, the first terminal device provided by this solution includes not only the first circuit board 201, the second circuit board 202, the processing unit 203 and the switch unit 204, but also the mobile industry processor interface MIPI routing. The processing unit 203 and the switch unit 204 are connected through the mobile industry processor interface MIPI routing, and the processing unit 203 obtains the identification potential based on the mobile industry processor interface MIPI routing. Therefore, this solution uses the original routing of the mobile terminal to achieve the purpose of obtaining the identification potential, saving the resources and routing space of the circuit board; in the specific implementation, other routings can also be used to obtain the identification potential according to actual needs.

[0047] In some embodiments, the first terminal device provided by the present solution includes, in addition to the first circuit board 201, the second circuit board 202, the processing unit 203 and the switch unit 204, different antennas on the second circuit board 202. The antennas of the second circuit board 202 are all connected to the switch unit and switched under the control of the switch unit.

[0048] In some embodiments, the first terminal device provided by this solution includes a mobile communication terminal, and may also include other terminal devices applicable to this solution.

[0049] In some embodiments, the switch unit of the first terminal device provided in the present application includes an identification port. In the second circuit board with different configurations, since the identification port of the switch unit is connected to different potentials, the corresponding identification potentials can be configured for the switch unit according to different configuration requirements, so as to distinguish different circuit boards so that the circuit boards can be connected according to the correct configuration requirements.

[0050] The above describes the principle of identifying circuit boards with different configurations inside the terminal device provided by the present application, and the structure of the terminal device composed of circuit boards with different configurations will be listed below.

[0051] Figure 3 This is a schematic diagram of the structure of another terminal device provided in an embodiment of the present application. Figure 3 As shown, the second terminal device provided in the embodiment of the present application includes a first circuit board 301, a first type second circuit board 302, a processing unit 303, a switch unit 304 and a power management unit 305.

[0052] The connection relationship of the internal units of the second terminal device provided in the embodiment of the present application is: the processing unit 303 is connected to the switch unit 304; the first resistor R1 is connected between the identification port of the switch unit 304 and the power port of the switch unit 304, and the identification port of the switch unit 304 and the power port of the switch unit 304 are both connected to the power management unit 305, wherein the first type second circuit board 302 formed is a circuit board of the first configuration.

[0053] In a specific implementation, the principle of identifying the circuit board of the first configuration through this scheme is: when the first circuit board 301 is connected to the first type second circuit board 302, the first circuit board 301 will detect the identification potential of the identification port of the switch unit 304 of the first type second circuit board 302. Since the identification port of its switch unit 304 is connected to the power port, the detected identification potential is pulled up to a high potential, which indicates that the first type second circuit board 302 is a circuit board of the first configuration, and the first circuit board 301 has been correctly connected to the circuit board of the first configuration.

[0054] In some embodiments, since the principle of the identification configuration is to connect the identification port of the switch unit to different potentials and distinguish circuit boards with different configurations by detecting the potential conditions, in addition to connecting the first resistor R1 between the switch unit identification port and the switch unit power port, other components that can play a similar role can also be connected, or the method of obtaining a high potential may not use the method of connecting the switch unit identification port to the power port, and other circuit connection methods can be set to pull the switch unit identification port to a high potential.

[0055] In some embodiments, the identification port and the power port of the switch unit may not be connected to the power management unit, but may be connected to other units according to actual needs.

[0056] In some embodiments, the first terminal device provided by this solution includes a mobile industry processor interface MIPI routing in addition to the first circuit board 301, the second circuit board 302, the processing unit 303 and the switch unit 304. The processing unit 303 and the switch unit 304 are connected through the mobile industry processor interface MIPI routing, and the processing unit 303 obtains the identification potential based on the mobile industry processor interface MIPI routing. Therefore, this solution uses the original routing of the mobile terminal to achieve the purpose of obtaining the identification potential, saving circuit board resources and routing space; in specific implementation, other routings can also be used to obtain the identification potential according to actual needs.

[0057] In some embodiments, the first terminal device provided by the present solution includes, in addition to the first circuit board 301, the second circuit board 302, the processing unit 303 and the switch unit 304, different antennas on the second circuit board 302. The antennas of the second circuit board 302 are all connected to the switch unit and switched under the control of the switch unit.

[0058] In some embodiments, the first terminal device provided by this solution includes a mobile communication terminal, and may also include other terminal devices applicable to this solution.

[0059] Figure 4 This is a schematic diagram of the structure of another terminal device provided in an embodiment of the present application. Figure 4 As shown, the third terminal device provided in the embodiment of the present application includes a first circuit board 401, a second circuit board of the second type 402, a processing unit 403, a switch unit 404 and a power management unit 405.

[0060] The connection relationship of the internal units of the third type of terminal device provided in the embodiment of the present application is: the processing unit 403 is connected to the switch unit 404; one end of the second resistor R2 is connected to the identification port of the switch unit 404, the other end of the second resistor R2 is grounded, and the power management unit 405 is connected to the second resistor R2, wherein the second type second circuit board 402 formed is a second configuration circuit board.

[0061] In a specific implementation, the principle of identifying the circuit board of the first configuration through this scheme is: when the first circuit board 401 is connected to the second type second circuit board 402, the first circuit board 401 will detect the identification potential of the identification port of the switch unit 404 of the second type second circuit board 402. Since the identification port of its switch unit 404 is grounded, the detected identification potential is pulled down to a low potential, which indicates that the second type second circuit board 402 is a circuit board of the second configuration, and the first circuit board 401 has been correctly connected to the circuit board of the second configuration.

[0062] In some embodiments, since the principle of the identification configuration is to connect the identification port of the switch unit to different potentials and distinguish circuit boards with different configurations by detecting the potential conditions, in addition to connecting the second resistor R2 between the switch unit identification port and the switch unit power port, other components that can play a similar role can also be connected, or the method of obtaining a low potential may not use the method of grounding the switch unit identification port, and other circuit connection methods can be set to pull the switch unit identification port down to a low potential.

[0063] In some embodiments, the identification port and the power port of the switch unit may not be connected to the power management unit, but may be connected to other units according to actual needs.

[0064] In some embodiments, the first terminal device provided by this solution includes a mobile industry processor interface MIPI routing in addition to the first circuit board 401, the second circuit board 402, the processing unit 403 and the switch unit 404. The processing unit 403 and the switch unit 404 are connected through the mobile industry processor interface MIPI routing, and the processing unit 403 obtains the identification potential based on the mobile industry processor interface MIPI routing. Therefore, this solution uses the original routing of the mobile terminal to achieve the purpose of obtaining the identification potential, saving circuit board resources and routing space; in specific implementation, other routings can also be used to obtain the identification potential according to actual needs.

[0065] In some embodiments, the first terminal device provided by the present solution includes, in addition to the first circuit board 401, the second circuit board 402, the processing unit 403 and the switch unit 404, different antennas on the second circuit board 402. The antennas of the second circuit board 402 are all connected to the switch unit and switched under the control of the switch unit.

[0066] In some embodiments, the first terminal device provided by this solution includes a mobile communication terminal, and may also include other terminal devices applicable to this solution.

[0067] The above describes a second terminal device structure including two configurations of the first configuration circuit board, and a third terminal device structure including two configurations of the second configuration circuit board. In some embodiments, the first circuit board and the second circuit board, which are used as the main board and the sub-board, are distinguished from different circuit boards by detecting different identification potentials configured in the circuit board switch unit. The configurations that can be identified are not limited to the above two. The corresponding identification potentials can be set according to the configuration at other identification ports of the sub-board switch unit to distinguish circuit boards with more configurations, so as to connect the circuit boards according to the correct configuration requirements and avoid the situation where the staff mix up the circuit boards. Moreover, this scheme does not require additional digital-to-analog converters and identification resistors, does not need to occupy the resources and wiring space of the main and sub-boards, and saves design costs; the configuration identification method proposed in this scheme utilizes the original interface of the terminal device, so it does not need to occupy the board-to-board connection pin resources of the main and sub-boards and the general input and output interface resources of the central processor as in the prior art, which again saves the resources and wiring space of the main and sub-boards.
