Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details.

The serial port connection method provided by the embodiment of the application can be applied to electronic devices such as a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, and the embodiment of the application does not limit the specific types of the electronic devices at all.
In order to explain the technical solution proposed in the present application, the following description will be given by way of specific examples.
Fig. 1 shows a schematic flow chart of a serial port connection method provided in the present application, which may be applied to any one of the electronic devices described above by way of example and not limitation.
External serial ports may generally include a Front panel serial port (Front UART), a back panel serial port (reader/RTM UART), and an SOL remote serial port. Whether each external serial port has data input or not can be detected, the input signal of each external serial port can be acquired, so that the external serial port with data input can be determined according to the input signal subsequently, and the effective connection between the serial port of the server and the external serial port is realized. The input signal refers to a serial port signal timing sequence, namely a level signal corresponding to a serial port.
In order to debug and perform subsequent maintenance on a system of a server, a serial port of the server needs to be connected to an external serial port. The number of the serial ports of the server is limited, so that the serial ports of the server are generally connected to an external serial port with data input in a detection mode, so that the system of the server can be conveniently debugged and maintained by receiving data from the external serial port. The external serial port with data input, namely the target external serial port, is determined, whether a target input signal exists in the input signal can be detected, the target input signal is used for indicating that the target external serial port has data transmission, and the external serial port corresponding to the target data signal is the target external serial port.
In some embodiments, based on the timing characteristics of the input signal of the serial port, the target input signal may be determined by:
and A1, judging whether the input signal has jump or not.
And A2, if the input signal with the jump exists, determining the input signal with the jump as the target input signal.
The input signal of the external serial port is a Transistor-Transistor Logic (TTL) level of positive Logic, which is abbreviated as TTL level. For a positive logic TTL level, its start bit is a bit with a value of 0, i.e., the start bit is a low level for one bit time; the stop bit is a bit with a value of 1, i.e. the stop bit is high for one bit time. For an external serial port with an idle line or a finished data transmission, a signal of the TTL level is always at a high level, namely, a value is 1. However, it should be noted that there are two cases of signal transition, one is high level transition to low level, and the other is low level transition to high level, and for a line with data transmission, the signal transition is always in an alternate transition of high level and low level. To determine whether the target input signal exists, it can be determined whether there is an input signal that transitions from high to low or an input signal that transitions alternately from high to low at all times. If such input signals are present, such input signals may be determined as target input signals.
And 103, if the target input signal exists, connecting the server serial port with a target external serial port.
After the target input signal is determined, the target external serial port can be further determined according to the target input signal. And after the target external serial port is determined, connecting the server serial port with the target external serial port so as to facilitate data transmission. Through the process, the efficiency and the timeliness of the connection between the server serial port and the external serial port can be improved.
In some embodiments, if there are a plurality of target input signals, in order to ensure stable transmission of important data, the step 103 specifically includes:
b1, detecting whether the number of the target input signals is larger than that of the server serial ports.
And B2, if the number of the target input signals is larger than that of the server serial ports, sequentially connecting the server serial ports with the target external serial ports according to the preset priority of the target external serial ports.
If a plurality of target input signals exist, a plurality of target external serial ports are to be connected. At this time, it is necessary to first determine whether the currently available server serial port can meet the connection requirement of the current target external serial port. If the currently available server serial port cannot meet the connection requirement of the current target external serial port, the preset priority of each target external serial port can be determined first, and then the available server serial port and each target external serial port are sequentially connected according to the priority of each target external serial port.
For ease of understanding, the following are illustrated: if 4 target input signals are determined simultaneously, 4 target external serial ports have data waiting to be transmitted. At this time, only 2 available server serial ports cannot meet the connection requirements of the target external serial ports at the same time, and the preset priority of the 4 target external serial ports needs to be determined. The method comprises the steps of presetting external serial ports with high priority, generally transmitting important data, preferentially connecting the external serial ports, then arranging the 4 target external serial ports according to the sequence of the preset priority from high to low, and sequentially connecting the server serial ports with the target external serial ports according to the arrangement sequence, namely, utilizing 2 server serial ports to be connected with the former two target external serial ports, and when the former two target external serial ports have no data transmission, respectively connecting the 2 server serial ports with the latter two target external serial ports, thereby ensuring the reliability of the important data transmission. Optionally, in order to ensure the integrity of data transmission, after 2 server serial ports are used to connect with the target external serial ports arranged in the first two positions, the remaining two target external serial ports may be discarded without connection.
In some embodiments, in order to avoid occupation of the server serial port by an idle external serial port, after connecting the server serial port with the target external serial port, the serial port connection method may include:
and C1, if the target input signal is changed into a non-target input signal in a preset time period, detecting whether a new target input signal exists.
C2, if there is new target input signal, switching the server serial port to connect to the new target external serial port.
For the target external serial port connected with the server serial port, whether data transmission is finished or not can be detected, namely whether the target external serial port is in an idle state without data transmission or not can be detected. Specifically, whether a target input signal is converted into a non-target input signal within a preset time period, for example, within 10 seconds, that is, whether a TTL level signal of a target external serial port is always 1 is detected. If the value is always 1, the target external serial port has no data transmission at present and is in an idle state. At the moment, if a new target input signal exists, the server serial port is switched and connected to a new target external serial port, wherein the new target external serial port is the external serial port corresponding to the new target input signal. By the method, the effective utilization rate of the server serial port and the timeliness of the connection of the new target external serial port can be improved. It should be understood that the switching connection here belongs to a specific application scenario of connection, that is, when a target external serial port connected to a server serial port is in an idle state, the server serial port may be switched to a new target external serial port, so as to improve flexibility of server serial port connection.
It can be understood that all the serial port connection methods described above belong to an intelligent connection scheme.
In some embodiments, a forced switch of the veneer management system may be received in addition to the intelligent connection. After the server serial port is connected with the target external serial port, the serial port connection method may include:
d1, if receiving the switching instruction of the single board management system, determining the serial port of the server to be switched and the external serial port to be connected according to the switching instruction.
And D2, connecting the serial port of the server to be switched to the external serial port to be connected.
If a forced switching instruction of the single board management system is received, the server serial port to be switched and the external serial port to be connected can be determined according to the switching specification, and then the server serial port and the external serial port to be connected are connected, so that the switching of the server serial port is realized.
In some embodiments, in order to improve the stability of important data transmission, the step D1 specifically includes:
d11, detecting whether an unconnected server serial port exists.
D12, if there is no unconnected server serial port, determining the server serial port to be switched according to the preset priority of each target external serial port.
D13, determining the external serial port to be connected according to the switching instruction.
After receiving a switching instruction of the board management system, the switching instruction has been specified for the external serial port to be connected. For a server serial port to be switched, firstly detecting whether an unconnected server serial port exists; if the serial ports of the current server are in a connection state, determining the external serial ports in connection, namely the preset priority of each target external serial port; and finally, selecting the target external serial port with the lowest preset priority as the serial port of the server to be switched. Therefore, after the external serial port to be connected and the server serial port to be switched are determined, the server serial port to be switched and the external serial port to be connected can be connected in a forced switching mode.
It should be understood that in the scenario where there is an unconnected server serial port, there may be two cases:
one is the case where the number of unconnected server serial ports is less than the number of external serial ports to be connected. For example, there are 1 serial port of the unconnected server and 3 external serial ports to be connected. 1 unconnected server can be connected with 1 external serial port; then determining 2 target external serial ports with the lowest preset priority from the target external serial ports, and taking the server serial ports connected with the 2 target external serial ports as server serial ports to be switched; and finally, connecting the 2 serial ports of the server to be switched with the 2 external serial ports to be connected.
The other is the case that the number of the unconnected server serial ports is equal to or larger than the number of the external serial ports to be connected. When the number of the unconnected server serial ports is equal to that of the external serial ports to be connected, the unconnected server serial ports can be sequentially connected with the external serial ports to be connected. And when the number of the unconnected server serial ports is larger than that of the external serial ports to be connected, the server serial ports with the number equal to that of the external serial ports to be connected can be randomly selected from the unconnected server serial ports and are sequentially connected with the external serial ports to be connected.
In some embodiments, in order to facilitate management of the server serial port, after connecting the server serial port with the target external serial port, the serial port connection method may include:
and recording the connection event of the server serial port through the single board management system.
Due to the fact that the number of the serial ports of the server and/or the number of the external serial ports are possibly large, errors occur in the data transmission process, and debugging of the server is affected. Therefore, every connection of the server serial port can be recorded, so that when a user subsequently manages the server serial port, the server serial port can be tracked and traced in real time, and the manageability of the server serial port is improved.
According to the method and the device, the input signal of the external serial port is obtained, the target input signal is determined from the input signal, the target external serial port corresponding to the target input signal is determined based on the target input signal, and finally the server serial port is connected with the target external serial port. The method can be used for timely connecting the external serial port with data transmission, so that the efficiency and the timeliness of the connection between the server serial port and the external serial port are improved.
Furthermore, when a plurality of target external serial ports are to be connected and the number of available server serial ports cannot meet the connection requirement, the target external serial ports can be connected according to the preset priority of the target external serial ports so as to improve the reliability of important data transmission.
Further, if a switching instruction of the board management system is received, the switching instruction of the board management system is preferentially satisfied. In the switching process, if the number of the external serial ports to be connected is larger than that of the available server serial ports, the server serial ports to be switched can be determined according to the preset priority level of the connected target external serial ports, and therefore the reliability of important data transmission is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
For convenience of understanding, the serial port connection method proposed in the embodiments of the present application is described below in a practical application scenario.
Fig. 2 shows a serial port switching method in a specific application scenario. The server serial port comprises a single board management system serial port and a system serial port, and the two serial ports can pass through a Field-Programmable Gate Array (FPGA) or a Complex Programmable Logic Device (CPLD). The CPLD/FPGA is internally provided with a data selector (MUX) which is used for taking any one path as a current data transmission line according to the requirement in the process of multi-path data transmission. After the single board management system serial port and the system serial port pass through the data selector, the serial port and the system serial port can be multiplexed to an external serial port. Such as the front panel serial port, the back panel serial port, and the SOL remote serial port shown in the figure. The data selector may be provided in two, such as a first data selector and a second data selector in the illustration. The first data selector can default to output a system serial port, and can also be set through the single board management system and configured as a troubleshooting serial port of the single board management system.
The second data selector may be configured in an intelligent switching mode. In the mode, the CPLD/FPGA detects input signals by acquiring the input signals of a front panel serial port, a rear panel serial port and an SOL remote serial port, and determines whether a target input signal exists. If the TTL level signal of the front panel serial port is detected to jump from high level to low level, the front panel serial port is indicated to have data transmission, and the second data selector can connect the currently available server serial port to the front panel serial port. After connection, if no jump of the TTL level signal of the front panel serial port is detected within a preset time period, the fact that the front panel serial port has no data transmission is indicated, and the second data selector can switch the server serial port connected with the front panel serial port to other external serial ports with data transmission. However, if other external serial ports with data transmission are not detected temporarily, the switching can be temporarily not performed until other external serial ports with data transmission are detected, and then the server serial port is switched to the other external serial ports with data transmission.
