Background
A single-ended signal refers to a signal input from a single end only, as opposed to a differential signal. A single-ended input is understood to mean that the signal has a reference terminal and a signal terminal. The reference terminal may be a ground plane, and the signal terminal may be a single I/O pin (e.g., general-purpose input/output (GPIO)), so as to implement signal transmission. That is, a single-ended signal is understood to be a signal expressed in terms of a change in voltage to ground, with "ground" as a reference point.
Because the server system is a complex and varied system formed by combining multiple modules, in the related art, a single-ended signal is often required to implement quick identification and function judgment of each module by the server system, so as to make corresponding configuration changes according to the type of the currently used module, for example: high speed serial computer expansion bus standard (PCIe) settings, temperature monitoring configuration, fan regulation policy changes, etc.
In practical applications, however, only one function is realized by a single-ended signal. If the server system needs to implement multiple functions, multiple single-ended signals are needed, but the design requirement is often not implemented due to the limited number of single-ended signals of the standard interface.

Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the related art, only one function can be realized through a single-ended signal, and no function multiplexing is supported. When the server system requires more single-ended signals to implement type identification or functionality, buses may be used instead, where pin limitations are imposed. However, in the existing hardware design, the pin count of the conventional slot is clearly specified, so that the bus cannot replace the single-ended signal. Furthermore, the use of a bus requires the addition of a master control device, resulting in excessive design costs and relatively complex designs.
In order to solve the above-mentioned problems, in the embodiments of the present invention, a signal transmission system may be implemented in a manner of software, hardware or a combination of software and hardware to form part or all of a computer device, where the computer device may be a terminal, a client, or a server, and the server may be a server, or may be a server cluster formed by multiple servers. In the following method embodiments, the execution subject is a computer device.
The signal transmission system in the embodiment of the invention can be a system which is positioned in the server system and can realize the rapid identification and function judgment of the server management system to each module and make corresponding configuration change through single-ended signals. According to the signal transmission system provided by the invention, the on state of the first switch or the second switch can be controlled by the timing gating switch control unit, so that the functional signals transmitted to the single-ended signal lines are controlled, and the same single-ended signal transmission line can transmit various functional signals to the main module control unit, so that multiplexing of the single-ended signal lines is realized, the design cost is reduced, and the purpose of expanding the functions of the single-ended signal is achieved under the condition of limited pin number.
Fig. 1 is a schematic diagram of a signal transmission system according to an exemplary embodiment. As shown in fig. 1, the signal transmission system includes a single-ended signal line 10, a first switch 20, at least one second switch 30, a timing gating switch control unit 40, and a main module control unit 50.
The single-ended signal line 10 has a single-ended signal input terminal and a single-ended signal output terminal for transmitting a multiplexed signal. The single-ended signal line is a signal line transmitting a single-ended signal, and a single-ended signal can only realize one function. In one example, the functions that can be implemented may include: the module in-place judgment, the module model judgment or the module function judgment is not limited in the present disclosure.
In order to realize multiplexing of single-ended signal lines, a plurality of switches are adopted to respectively control the time when a plurality of different functional signals are input to the single-ended signal lines, so that the purpose of expanding the single-ended signal functions is achieved.
The first switch 20, the first connection end of the first switch 20 is connected with the first functional signal output end, and the second connection end is connected with the single-ended signal input end. Whether the first function signal is input to the single-ended signal line can be controlled by the first switch 20. When the first switch 20 is in the on state, the first functional signal may be transmitted to the single-ended signal input terminal through the first functional signal output terminal, and the single-ended signal line transmits the first functional signal, thereby implementing a function corresponding to the first functional signal. When the first switch 20 is in the off state, the first functional signal cannot be transmitted to the single-ended signal line, and thus the function corresponding to the first functional signal cannot be realized.
And a second switch 30, wherein a first connection end of the second switch is connected with the second functional signal output end, and a second connection end of the second switch is connected with the single-ended signal input end. In the present invention, the second switch 30 may include one or more. In one example, when a plurality of second switches are included, a schematic diagram of the signal transmission system may be as shown in fig. 2. Fig. 2 is a schematic diagram of another signal transmission system according to an exemplary embodiment. And the second different switches correspondingly control whether the second different functional signals are transmitted into the single-ended signal line. The second function signals have a one-to-one correspondence with the second switches, i.e. one second switch controls one second function signal. In the present invention, the different second function signals are different in the functions correspondingly realized, and the functions realized by the second function signals are also different from the functions realized by the first function signals.
The timing gating switch control unit 40 is connected to the control end of the first switch 20 and the control end of the second switch 30, and controls the first switch 20 to be turned on to transmit the first functional signal or controls the second switch 30 to be turned on to transmit the second functional signal in a time-sharing manner. The switch control unit 40 can determine that the switch is required to be in a conducting state in the current signal transmission system, so as to control the corresponding functional signal to be transmitted. Since the single-ended signal line can only transmit one functional signal at a time, the timing gating switch control unit 40 controls whether the first switch and the second switch are turned on or not in a time-sharing conduction mode. That is, one of the first switch or each second switch is controlled to be in an on state and the other switches are controlled to be in an off state by adopting a time-sharing mode, so that the condition that a plurality of functional signals are simultaneously input to a single-ended signal line is avoided, and the stability of signal transmission is improved.
The main module control unit 50 is connected to the single-ended signal output end, and is configured to receive the multiplexed signal with the preset time length input by the single-ended signal input end. The main module control unit 50 is configured to receive the multiplexed signal transmitted by the single-ended signal line, and further perform a corresponding function according to the received multiplexed signal. The multiplexing signal may be a first functional signal or a second functional signal, and whether the received multiplexing signal is the first functional signal or the second functional signal may be determined according to the detection time period. That is, the signal detected by the main module control unit 50 in the first period is the first functional signal, and the signal detected in the second period is the second functional signal.
Through the embodiment, the on state of each switch is controlled by the timing gating switch control unit, so that the first functional signal or the second functional signal is controlled in a time-sharing manner and transmitted to the single-ended signal line, and the main module control unit can realize the corresponding first function or the corresponding second function according to the received first functional signal, thereby realizing the function multiplexing of the single-ended signal and achieving the purpose of expanding the single-ended signal function.
In an embodiment, when a plurality of second function signals are included, the timing gating switch control unit 40 periodically time-division turns on the first switch or each second switch according to the total number of connected first switches and second switches. In order to facilitate that a plurality of functional signals can be transmitted to the single-ended signal input end of the single-ended signal line, and further realize the functions corresponding to the functional signals, the conducting sequence of the switches is determined according to the total number of the first switch and the second switch, and therefore the first switch or the second switch is controlled to conduct periodically according to the conducting sequence. For example: the number of the second switches is 3, and the total number of the first switches and the second switches is 4. Thus, the single-ended signal line can transmit four kinds of functional signals that can realize different functions. For ease of description, 3 different second switches are replaced with switch 2, switch 3 and switch 4. Switch 2 controls the transmission of functional signal a, switch 3 controls the transmission of functional signal b, and switch 4 controls the transmission of functional signal c. The timing gating switch control unit 40 sequences the conducting time of the four switches, and the time-sharing gating control unit controls the first switch, the switch 2, the switch 3 and the switch 4 to be in a conducting state, so as to control the first functional signal, the functional signal a, the functional signal b and the functional signal c to be periodically transmitted to the single-ended signal line according to the corresponding conducting state of the switch.
In another embodiment, the detection period of the main module control unit 50 detecting the first functional signal or the second functional signal corresponds to the on time of the gating switch control unit 40 to turn on the first switch or the second switch. That is, the main module control unit 50 detects that the detection time of each functional signal corresponds to the on time of each switch controlled by the gate switch control unit, and then the main module control unit can determine whether the multiplexed signal is the first functional signal or the second functional signal according to the detection time period of the detected multiplexed signal, thereby realizing the corresponding function.
In an implementation scenario, the process of detecting each function signal by the master module control unit 50 may be as shown in fig. 3. Fig. 3 is a schematic diagram illustrating signal detection according to an exemplary embodiment. In fig. 3, the first switch is used to control the transmission of the first function signal, and the number of the second switches may be plural, including the switch 2, the switch 3, and the switch 4. Wherein the switch 2 controls the transmission of the functional signal a, the switch 3 controls the transmission of the functional signal b, and the switch 4 controls the transmission of the functional signal c. In order to facilitate distinguishing the second time periods corresponding to the second switches, the conduction time corresponding to the switch 2 is determined to be the second conduction period, the conduction time corresponding to the switch 3 is determined to be the third conduction period, and the conduction time corresponding to the switch 4 is determined to be the fourth conduction period. When the main module control unit 50 receives the multiplexed signal according to the single-ended signal line for detection, the multiplexed signal detected in the first period is a first functional signal, the multiplexed signal detected in the second conduction period is a functional signal a, the multiplexed signal detected in the third conduction period is a functional signal b, and the multiplexed signal detected in the fourth conduction period is a functional signal c. In fig. 3, in order to facilitate distinguishing between functional signals according to the illustration, different level states are employed for different functional signals. In practical application, the level state of each functional signal depends on the corresponding requirement of the functional signal when the functional signal is transmitted, and the invention is not limited.
In yet another embodiment, since there is only one single-ended signal input end of the single-ended signal line, the first switch 20, each second switch 30, and the timing gating switch control unit 40 may be integrated into the same sub-module, and the function time-sharing output unit of the sub-module controls the transmission of the first function signal or the second function signal for signal transmission and management. In one example, the main module control unit may include a system unit, a logic unit, and a management unit, and when connected to the single-ended signal output end of the single-ended signal line, the main module control unit may connect with the logic unit, and identify, by using the logic unit, a specific functional signal corresponding to the currently received multiplexed signal. In an implementation scenario, a schematic structure of the integrated signal transmission system may be shown in fig. 4. Fig. 4 is a schematic structural diagram of yet another signal transmission system according to an exemplary embodiment.
Based on the same inventive concept, the invention also provides a signal transmission method which is applied to the main module control unit in any signal transmission system.
Fig. 5 is a flowchart of a signal transmission method according to an exemplary embodiment. As shown in fig. 5, the signal transmission method includes the following steps S501 to S502.
In step S501, a detection period for detecting the multiplexed signal is determined.
In the embodiment of the invention, the multiplexing signal refers to a functional signal obtained by multiplexing a single-ended signal line. The multiplexed signal may include the first functional signal or the second functional signal. The second functional signals that can be transmitted to the single-ended signal line are not limited to one, and may include a plurality of different second functional signals that can realize different functions. In the transmission process, when the single-ended signal line is multiplexed, functional signals for realizing different functions are transmitted in different time periods. Therefore, in order to improve the accuracy of the function signal reception, the specific function signal corresponding to the currently received multiplexing signal is clarified, and then the detection time period for detecting each function signal is determined according to the transmission time of each function signal. For example: the first time period is determined as a detection time period for detecting the first functional signal when the first functional signal is transmitted in the first time period. The second function signal is transmitted in a second time period, and the second time period is determined as a detection time period for detecting the second function signal. In different detection time periods, different functional signals are correspondingly detected, and further the detection time of each functional signal is helped to be clear, so that when the functional signals are received, specific functional signals corresponding to the multiplexing signals currently received can be clear according to the detection time periods, and multiplexing of single-ended signal lines is achieved.
In step S502, a first functional signal or a second functional signal transmitted by a single-ended signal line for a preset time period is received.
In the embodiment of the invention, when the single-ended signal line is adopted for signal transmission, each functional signal is transmitted in an alternating mode, so that the purpose of multiplexing the single-ended signal line is achieved. In order to facilitate the main module control unit to determine the function to be realized by the signal according to the received function signal, when transmitting, each function signal is transmitted according to the preset time length, and then the main module controls the single-ended to receive the first function signal or the second function signal with the preset time length when receiving the function signal. And according to the received multiplexing signal, the signal detected in the first time period is used as a first functional signal, and the signal detected in the second time period is used as a second functional signal.
In one implementation, the predetermined time period may be 500 milliseconds (ms). When the signal transmission is carried out, after each functional signal is transmitted for 500ms, the next switch is switched on to control the next functional signal to be transmitted. In another implementation scenario, in order to facilitate the main module control unit to determine that the functional signal on the single-ended signal line is transmitted, it is necessary to start to detect the functional signal, and ensure that the detected functional signal is a stable signal, when the multiplexed signal is received, the main module control unit may wait for a certain period of time and start to detect the functional signal. The waiting period may be 200ms. In still another implementation scenario, the time level of the preset time length and the waiting time length may be a millisecond level or a second level, and may be set according to the requirement.
Through the above embodiment, the main module control unit can determine when to collect each functional signal according to the predetermined detection time of each functional signal, so that when the received multiplexed signal is received, whether the specific functional signal corresponding to the received multiplexed signal is the first functional signal or the second functional signal can be determined according to different detection time periods, thereby achieving the purpose of single-ended signal function expansion.
In one embodiment, when a plurality of second function signals are included, that is, the number of function signals that the master module control unit can detect is greater than 2. The determination of the detection time period for detecting each functional signal will be described in detail below. Because the single-ended signal lines alternately transmit each functional signal when multiplexing, in order to improve the detection accuracy, the detection periods of detecting the first functional signal and each second functional signal are determined so as to determine the transmission rule of each functional signal when each functional signal is transmitted on the single-ended signal lines. According to the determined detection period, a first time period for detecting the first functional signal and a second time period for detecting each second functional signal are respectively determined so as to perform targeted detection.
In another embodiment, the detection period is the same as the transmission period of each functional signal transmitted by the single-ended signal line, that is, the transmission period of each functional signal transmitted by the single-ended signal line is the same as the detection period of the main module control unit periodically detecting each functional signal. For example: the transmission period is periodically transmitted according to the sequence of the first functional signal, the functional signal a, the functional signal b and the functional signal c, so that when the main module control unit detects each functional signal according to the detection period, the main module control unit also periodically detects according to the sequence of the first functional signal, the functional signal a, the functional signal b and the functional signal c, and further the main module control unit obtains the accuracy of the functional signals, thereby being beneficial to avoiding the occurrence of the condition of realizing other functions by adopting the current functional signals, and realizing multiplexing of single-ended signal lines and simultaneously ensuring accurate transmission of the functional signals.
Fig. 6 is a flow chart of another signal transmission method according to an exemplary embodiment. As shown in fig. 6, the signal transmission method includes the following steps.
In step S601, a detection period for detecting the multiplexed signal is determined.
In step S602, a first functional signal or a second functional signal transmitted by a single-ended signal line for a preset time period is received.
In step S603, signal analysis is performed based on the signal state of the received multiplexed signal.
In the embodiment of the invention, each functional signal is a functional signal with a fixed level state, and the main module control unit can identify according to the level state of the received functional signal. In order to facilitate the realization of the function corresponding to the function signal according to the detected function signal, signal analysis is performed according to the signal state of the received multiplexing signal, so that the function to be executed is rapidly identified according to the analysis result, and the function is correspondingly configured. For example: PCIe settings, temperature monitoring configurations, fan regulation policy changes, etc. are performed. In an implementation scenario, taking the signal transmission system shown in fig. 3 as an example, after receiving the multiplexed signal, the logic unit in the master module control unit analyzes the multiplexed signal, and transmits the analyzed signal state of the multiplexed signal to the system unit and the management unit according to the analysis result, so that the system unit and the management unit automatically implement corresponding configuration change and resource allocation according to the received functional state.
Through the above embodiment, the main module control unit can detect the single-ended signal state according to the determined detection time period, so as to obtain the signal states of all functions, and realize the multiplexing of the single-ended signal functions.
In an implementation scenario, the signal level states of each functional signal during transmission may be as shown in fig. 3, the signal transmission system is as shown in fig. 4, and the signal transmission process is as follows:
in the submodule, 4 kinds of functional signals capable of executing different functions can be controlled to be transmitted to the single-ended signal line, so that the functional multiplexing of the single-ended signals is realized. The transmission of the first functional signal is controlled by the first switch, the transmission of the functional signal a is controlled by the switch 2, the transmission of the functional signal b is controlled by the switch 3, and the transmission of the functional signal c is controlled by the switch 4. The timing gating switch control unit controls the conduction period of the first switch, the switch 2, the switch 3 and the switch 4 to be independently conducted, namely, the first switch is controlled to be in a conduction state firstly, after the conduction time length meets the preset time length, the first switch is disconnected, the switch 2 is controlled to be in a conduction state, and the like, until the conduction time length of the switch 4 meets the preset time length, the switch 4 is disconnected, and the first switch is conducted again. The logic unit in the main module control unit determines the detection periods of the first functional signal, the functional signal a, the functional signal b and the functional signal c according to the conduction period, and determines the arrival detection time period of each functional signal according to the conduction duration of each functional signal. In the signal transmission process, the function time-sharing output unit in the sub-module controls the transmission of each function signal to the single-ended signal line according to the conduction period, the logic unit in the main module control unit detects and analyzes different function signals in different detection time periods according to the detection period corresponding to the conduction period, and the signal state of the function signals obtained by analysis is transmitted to the system unit and the management unit for corresponding configuration and resource allocation, so that the purpose of multiplexing the functions of the single-ended signals is achieved.
According to the embodiment, under the condition of limiting the number of pins, the function expansion requirement of the single-ended signal can be met, and the function multiplexing of the single-ended signal line is realized, so that the newly added configuration in the existing system is not limited by the number of single-ended signals.
Based on the same inventive concept, the invention also provides a signal transmission method applied to the main module control unit in any signal transmission system.
