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, the detection of whether the extrapolation device is plugged in place is based on the server system. After the normal installation of the server is completed and the power-on is performed, the bandwidth and the rate of the extrapolation device are acquired through a lspci instruction (an instruction for displaying the information of all peripheral component interconnect standards (Peripheral Component Interconnect, PCI) devices) issued by the system, and then judgment is performed based on the comparison between the uplink bandwidth allocated by the CPU and the bandwidth of the extrapolation device itself. However, by adopting the mode for judging, the detection needs to be carried out after the installation of the server is completed, the detection time is long, and the efficiency of checking the plugging condition of the external equipment is low.
In order to solve the above problems, an embodiment of the present invention provides a plugging in position detection device, which is suitable for detecting whether an external plugging device is plugged in position in a use scenario. In the plugging in position detection device provided by the invention, the pressure information received by the elastic sheet in the female connector slot can be detected by the pressure-sensitive sensor connected with the elastic sheet in the female connector slot when the male plug of the external plugging device is plugged into the female connector, and the pressure information is transmitted to the baseboard management controller, so that the baseboard management controller can determine whether the external plugging device is plugged in position. Therefore, when the plugging state of the plugging equipment is detected, the plugging state can be detected after the baseboard management controller is started, so that the detection process of the plugging state is faster and more convenient, and the production and maintenance efficiency is improved.
Fig. 1 is a schematic diagram of a plug-in position detection device according to an exemplary embodiment. As shown in fig. 1, the plug-in position detection device 100 includes the following components: the connector female 10, the pressure sensitive sensor 20, the routing chip 30, and the baseboard management controller 40 route the chip 30.
The connector female 10 is used for plugging the male of the external plug-in equipment.
In an embodiment of the invention, the connector is a component for establishing a communication connection between the external plug-in device and the electronic device in which the plug-in to place detection device is located. When the external plug equipment is needed to be accessed, the male plug of the external plug equipment is inserted into the slot of the female plug of the connector.
In one example, the interface function of the connector header 10 is a custom function. The connector may be a Slimline connector.
The pressure sensor 20 is connected with the elastic sheet in the slot of the connector female head 10 and is used for detecting the pressure information of the elastic sheet.
In the embodiment of the present invention, the slot of the female connector 10 includes at least one elastic sheet, and when the male connector of the external plug device is inserted into the female connector 10, the elastic sheet in the slot is elastically deformed due to pressure. Therefore, to determine the pressure condition of the spring in the slot of the female connector 10, the pressure sensor 20 is connected to the spring in the slot of the female connector 10 to detect the pressure information of the spring connected thereto.
In an example, the number of the pressure-sensitive sensors 20 may be at least 1, the number of the pressure-sensitive sensors 20 has a corresponding relationship with the number of the elastic sheets in the slot of the connector female 10, and the more the number of the pressure-sensitive sensors 20 is, the more targeted the corresponding detected pressure information is, so that the occurrence of the condition of false detection can be effectively avoided or reduced, and the accuracy of the detection result for determining the plugging state is improved.
In another example, the number of the pressure-sensitive sensors is the same as the number of the elastic sheets, and each pressure-sensitive sensor detects pressure information of one elastic sheet. For example: if the connector female 10 is an X8 PCI-E slot and includes 8 elastic pieces, the number of the pressure-sensitive sensors 20 is 8, and each pressure-sensitive sensor 20 is correspondingly connected with one elastic piece to detect the pressure information of the elastic piece connected with the pressure-sensitive sensor, so that the obtained pressure information has more pertinence, and the accuracy of detecting whether the external plugging device is plugged in place by the subsequent baseboard management controller 40 is improved.
The routing chip 30 has a first end connected to the pressure sensor 20 and a second end connected to the baseboard management controller 40 for transmitting pressure information detected by the pressure sensor 20 to the baseboard management controller 40.
In one embodiment, the routing chip 30 may be an integrated circuit bus switch (Inter-Integrated Circuit Switch, I) 2 C Switch) chip, canThe pressure information detected by the pressure sensor 20 can be transmitted to the baseboard management controller 10 based on the integrated circuit bus protocol. Since the baseboard management controller 40 cannot directly use the pressure information detected by the pressure sensor 20, when the pressure sensor 20 detects the obtained pressure information, the pressure information passes through I 2 C protocol, transmitting pressure information to I 2 Data conversion is carried out in the C Switch chip, and pressure information is converted into I 2 The C signal is transmitted to the baseboard management controller 40, and the baseboard management controller 40 obtains I according to the obtained I 2 The C signal detects whether the male plug of the extrapolation device is plugged in place.
The baseboard management controller 40 is used to determine whether the male plug of the external device is plugged into place based on the pressure information.
In the embodiment of the present invention, the baseboard management controller (Baseboard Management Controller, BMC) 40 is a small operating system that can be independent of the server system, and can perform operations such as remote management, monitoring, installation, and restarting on the electronic device in which the machine is located when the machine is in an un-powered state. Therefore, the baseboard management controller 40 can determine whether the pressure received by the elastic sheet is greater than or equal to the pressure threshold value of the inserted in-place according to the received pressure information, and further determine whether the insertion between the male end of the external insertion device and the female end of the connector is in place, so as to achieve the purpose of detection.
Through the embodiment, when the male plug of the external plugging device is inserted into the female connector, the baseboard management controller can detect whether the male plug of the external plugging device is plugged in place according to the pressure information transmitted by the pressure sensor connected with the elastic sheet in the female connector slot, so that the detection process of the plugging state is faster and more convenient, and the production and maintenance efficiency is improved.
Furthermore, because the plugging in position detection device has simple structure and high line reusability, when detecting the plugging state of a plurality of external plugging devices, the detection related codes can be reused, thereby being beneficial to saving the development cost.
In an embodiment, if the number of the pressure sensors 20 is plural, the routing chip 30 transmits the pressure information detected by each pressure sensor 20 to the baseboard management controller 40, so that the baseboard management controller 40 determines whether the pressure received by each spring in the socket is greater than or equal to the pressure threshold value according to the received pressure information, and further determines whether the male plug of the external device is plugged in place. For example: if the pressure born by one elastic sheet is smaller than the pressure threshold value, the male head of the externally inserted equipment is determined to be not inserted in place. If the pressure born by each elastic sheet is greater than or equal to the pressure threshold value, the male plug of the external plug device is determined to be plugged in place.
In another embodiment, when the male plug of the external device is inserted into the slot of the female connector 10 and contacts with the spring in the slot, communication interaction can be performed between the male plug of the external device and the female connector 10 based on the protocol of the high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE), and a path through which the return flow of the PCIE signal flows during the interaction includes a signal Ground (GDN). Therefore, when the pressure sensor 20 detects the pressure information of the spring plate in the slot of the connector female 10, the pressure information of the spring plate can be detected by detecting the strength of the GDN flowing through the spring plate.
In practical applications, ac ground and signal ground cannot be shared. Therefore, if the pressure sensor 20 is in the power-on state for a long time, detecting the pressure information of the spring sheet is easy to interfere with the signal transmission of the ac ground, and thus affects the operation of other modules. Therefore, to avoid this, the invention also provides another plug-in position detection device.
Fig. 2 is a schematic diagram of another plug-in position detection device according to an exemplary embodiment. As shown in fig. 2, plug-in-place detection device 100 also includes a voltage regulator 50.
A first end of voltage regulator 50 is coupled to pressure sensitive sensor 20 for powering pressure sensitive sensor 20. A baseboard management controller 40 is connected to a second terminal of the voltage regulator 50 for controlling whether the voltage regulator 50 supplies power to the pressure sensitive sensor 20.
In an embodiment of the present invention, baseboard management controller 40 may control whether voltage regulator 50 is in a power supply state via an enable signal. For example: if the enable signal sent by baseboard management controller 40 to voltage regulator 50 is "en=0", voltage regulator 50 may be controlled to be in a power supply state, so that voltage regulator 50 may supply power to pressure-sensitive sensor 20, and further, pressure-sensitive sensor 20 may be controlled to perform pressure-sensitive detection. If the enable signal sent by baseboard management controller 40 to voltage regulator 50 is "en=1", voltage regulator 50 may be controlled to be in a non-power-supplied state, such that voltage regulator 50 stops supplying power to pressure-sensitive sensor 20, and further, pressure-sensitive sensor 20 is controlled to stop performing pressure-sensitive detection.
In one embodiment, if the number of pressure sensitive sensors 20 is plural, then baseboard management controller 40 can control whether voltage regulator 50 is supplying power to pressure sensitive sensors 20 based on the amount of information from which pressure information was obtained. For example: if the number of the received pressure information is less than the number of the pressure-sensitive sensors, and then the number of the non-stressed elastic pieces exists in the slots of the connector female head 10, so that the installation of the electronic equipment where the plugging-in position detection device is located is prevented from being influenced, the voltage regulator 50 is controlled to continuously supply power to the pressure-sensitive sensors 20 until the fact that the male head of the plug-in equipment is plugged in position is determined. If the number of the received pressure information is equal to the number of the pressure sensors, the elastic sheets in the slots of the female connector 10 are stressed, and then when the male connector of the externally inserted equipment is plugged in place, the voltage regulator 50 is controlled to be in a non-power supply state, and power supply to the pressure sensors 20 is stopped, so that the accuracy of alternating-current ground signal transmission is ensured.
Fig. 3 is a schematic diagram of still another plug-in position detection device according to an exemplary embodiment. As shown in fig. 3, the plug-in-place detection device further includes a status light 60 connected to the baseboard management controller 40. Fig. 3 is a schematic diagram of another plug-in position detection device according to an exemplary embodiment. The status light 60 is used for prompting the plugging status of the connector female 10 and the male of the external plugging device. The plugged state may include plugged into place or unplugged into place. The status lights 60 are correspondingly displayed in different colors for different plugging states. For example: if the plugging status is plugged in place, the baseboard management controller 40 can control the status light 60 to display green. If the plugged status is not plugged in place, the baseboard management controller 40 can control the status light 60 to display red.
Based on the same inventive concept, the invention also provides electronic equipment, which comprises any one of the plug-in-place detection devices provided by the invention, so that when detecting whether the plug-in equipment is plugged in place, the detection can be directly performed through the started baseboard management controller without waiting for the detection after the electronic equipment is started to enter the system, thereby ensuring that the process of detecting whether the plug-in equipment is plugged in place is simpler and more convenient, being beneficial to improving the detection rate and being beneficial to improving the maintenance efficiency. It should be noted that, the execution body may be a plug-in state detection device of the external plug-in device, and the device may be implemented in a mode of software, hardware or a combination of software and hardware to form part or all of an electronic device, where the electronic 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.
Based on the same inventive concept, the invention also provides a plugging state detection method of the external plugging equipment, which is applied to any one plugging in-place detection device provided by the invention. In the following method embodiments, the execution subject is a server as an example.
The method for detecting the plugging state of the external plugging device is suitable for detecting the use scene of whether the external plugging device in the server is plugged in place. According to the plugging state detection method of the external plugging device, provided by the invention, under the condition that the male head of the external plugging device is plugged with the female head of the connector, the pressure information of the elastic sheet in the female head slot of the connector is detected through the pressure-sensitive sensor, the pressure value of the elastic sheet under pressure is determined, and then the plugging state between the male head of the external plugging device and the female head of the connector is determined according to the comparison result between the pressure value and the pressure threshold value, so that the process of detecting whether the external plugging device is plugged in place is simpler and more convenient, the detection rate is improved, and the maintenance efficiency is improved.
Fig. 4 is a flowchart of a plug state detection method of an external plug device according to an exemplary embodiment. As shown in fig. 4, the method for detecting the plugging state of the plug-in device includes the following steps S401 to S402.
In step S401, in the case where the male plug of the external device is plugged into the female plug of the connector, pressure information detected by the pressure sensor is acquired.
In the embodiment of the invention, the pressure information is used for determining the pressure value of the elastic sheet in the female connector slot. Under the condition that the male head of the external plug-in equipment is plugged with the female head of the connector, the elastic piece in the female head slot of the connector is deformed due to the influence of external force. Because the external plug equipment is plugged into the connector female, communication interaction can be carried out between the internal parts through PCIE signals, in order to determine the pressure information of the elastic sheet in the connector female slot, GDN signals in the PCIE signals can be sent to the pressure-sensitive sensor and then detected by the pressure-sensitive sensor, and therefore the pressure information corresponding to the elastic sheet is obtained.
In an example, if the number of pressure-sensitive sensors connected to the connector female is plural, multi-dimensional detection can be performed when detecting the pressure information of the elastic sheet, so as to help to avoid or reduce occurrence of false detection.
In another example, if the number of the pressure-sensitive sensors is the same as the number of the elastic sheets, and each pressure-sensitive sensor correspondingly detects the pressure information of one elastic sheet, the pressure value received by each elastic sheet in the female connector slot is helped to be clear, and the obtained pressure information is more targeted, so that the detection accuracy is helped to be improved.
In step S402, the plugging state between the male connector and the female connector of the external plugging device is determined by comparing the pressure value with the pressure threshold value.
In the embodiment of the invention, the pressure threshold value can be understood as a minimum pressure value of the pressure applied to the elastic sheet in the female connector slot when the male connector of the external plug device is plugged in place. If the pressure value of the pressure applied to the elastic sheet is smaller than the pressure threshold, the pressure applied to the elastic sheet is characterized in that the pressure applied to the elastic sheet does not meet the requirement of plugging in place, plugging between the external plugging equipment and the connector female head may not be installed in place or the situation of poor contact exists, the plugging state is abnormal, and then the fact that the external plugging equipment is not plugged in place can be determined. If the pressure value of the pressure received by the elastic sheet is larger than or equal to the preset pressure threshold value, the pressure received by the elastic sheet is characterized in that the pressure received by the elastic sheet meets the requirement of plugging in place, the plugging state between the male head of the external plugging device and the female head of the connector is relatively stable, the plugging state is normal, and then the plugging in place of the external plugging device can be determined. In one example, the specific value for the pressure threshold may be determined by experimental measurements.
Therefore, in order to determine the plugging state between the external plugging device and the connector female, the acquired pressure information is compared with a preset pressure threshold value, so that whether the external plugging device is plugged in place is determined according to the comparison result.
In an example, when the number of the pressure-sensitive sensors is multiple, and the different pressure-sensitive sensors correspondingly detect the pressure information of the different shrapnel, the pressure values corresponding to the pressure information are respectively determined, and then whether the extrapolation device is plugged in place is determined according to the comparison result between the pressure values and the pressure threshold. If at least one pressure value is less than the pressure threshold, it is determined that the extrapolation apparatus is not plugged in. If the pressure values are all greater than or equal to the pressure threshold, then the extrapolation device is determined to be plugged in place.
Through the embodiment, under the condition that the male head of the external plugging device is plugged with the female head of the connector, the pressure information of the elastic sheet in the female head slot of the connector is detected through the pressure-sensitive sensor, the pressure value of the pressure received by the elastic sheet is determined, and then the plugging state between the male head of the external plugging device and the female head of the connector is determined according to the comparison result between the pressure value and the pressure threshold value, so that the process of detecting whether the external plugging device is plugged in place is simpler and more convenient, the detection rate is improved, and the maintenance efficiency is improved.
Fig. 5 is a flowchart of another plug-in status detection method of an external plug-in device according to an exemplary embodiment. As shown in fig. 5, the method for detecting the plugging state of the plug-in device includes the following steps.
In step S501, in the case where the male plug of the external device is plugged into the female plug of the connector, pressure information detected by the pressure sensor is acquired.
In step S502, the plugging state between the male connector and the female connector of the external plugging device is determined by comparing the pressure value with the pressure threshold value.
In step S503, the plugging state between the external plugging device and the connector female is prompted by controlling the color change of the status light.
In the embodiment of the invention, in order to facilitate the user to clearly determine the plugging state between the plug-in equipment and the connector female, the color of the status lamp is controlled to prompt, so that the user clearly detects whether the user performs targeted detection. That is, different colors are used to represent different plugging states, for example: color a indicates plugged-in position and color b indicates unplugged-in position.

Fig. 6 is a flowchart of a method for detecting a plug state of a further plug device according to an exemplary embodiment. As shown in fig. 6, the method for detecting the plugging state of the plug-in device includes the following steps.
In step S601, the baseboard management controller is started to detect whether an external device is plugged in place.
In the embodiment of the invention, because the BMC is a small operating system which can be independent of the outside of the server system, the operations of remote management, monitoring, installation, restarting and the like can be executed on the server when the machine is in an un-started state. Therefore, in order to facilitate rapid judgment of whether the external plugging device is plugged in place, the server is connected with alternating current (Alternating Current, AC) under the condition that the male head of the external plugging device is plugged in with the female head of the connector, and the baseboard management controller is started under the condition that the server is not started, so that the baseboard management controller can enter a working state, and then the started baseboard management controller controls the pressure-sensitive sensor to conduct pressure-sensitive detection, and the detection is carried out after the installation of the server is completed, so that the detection of whether the external plugging device is plugged in place is shortened, and the maintenance detection efficiency is improved.
In step S602, pressure information detected by the pressure sensor is acquired.
In step S603, a pressure value of the elastic sheet in the female socket of the connector under pressure is determined according to the pressure information.
In step S604, the plugging state of the extrapolation apparatus is determined from the comparison between the pressure value and the pressure threshold value.
In one embodiment, the pressure threshold is pre-stored in the baseboard management controller.
In step S605, according to the plugging state of the plugging device, the baseboard management controller controls whether the pressure sensor continues to detect the pressure information of the spring piece in the connector female socket.
In an embodiment of the invention, the pressure sensitive sensor is a pressure sensitive test based on the GDN sent by the connector header. However, in practical applications, other modules in the server also need to receive the GDN to perform other functions, and if the pressure-sensitive sensor is in the pressure-sensitive detection state for a long time, the other modules in the server are easy to interfere with receiving the ac signal. Therefore, in order to avoid interference with other modules receiving the alternating current signal, the baseboard management controller controls whether the pressure-sensitive sensor continues to perform pressure-sensitive detection according to the plugging state of the plugging device.
In an example, if the external plug device is plugged in place, the plugging state between the external plug device and the connector female is characterized as normal, so that the pressure-sensitive detection is not required to be continued, and the power supply to the pressure-sensitive sensor is stopped. If the external plugging equipment is not plugged in place, the plugging state between the external plugging equipment and the connector female head is abnormal, and the plugging condition of the external plugging equipment needs to be continuously detected, so that the condition of false detection is avoided, and power is continuously supplied to the pressure-sensitive sensor.
Through the above embodiment, whether the pressure-sensitive sensor is continuously detected according to the detected plugging state can be controlled by the started baseboard management controller, so that the pressure-sensitive detection can be ensured to be performed normally, other modules are prevented from being interfered, the plugging state detection process is more convenient and rapid, and the production and maintenance efficiency is improved.
In an embodiment, when a plurality of external plug-in devices are installed in the server, under the condition that the baseboard management controller is started, plug-in state detection is directly carried out on the plugged-in external plug-in devices, detection is carried out after all the external plug-in devices are installed, and further plug-in state detection time can be effectively shortened, detection efficiency is improved, and therefore quick positioning of external plug-in devices with abnormal plug-in is facilitated, and maintenance efficiency is improved.
In an implementation scenario, taking a Slimline connector as an example, in combination with the plugging-in position detecting device provided in fig. 3, a process of detecting whether a plugging state between the external plugging device and the connector female is plugged in position may be as shown in fig. 7. Fig. 7 is a flowchart of a method for detecting a plug state of a further plug device according to an exemplary embodiment.
In step S701, each spring piece in the female slot of the Slimline connector is connected to a pressure sensor.
In the embodiment of the invention, each elastic piece in the female slot of the Slimline connector is respectively connected with one pressure-sensitive sensor so as to determine the pressure value received by each elastic piece in the female slot of the connector, and further the obtained pressure information is more targeted.
In step S702, through I 2 And the C Switch chip establishes communication connection between the plurality of pressure-sensitive sensors and the baseboard management controller.
In the embodiment of the invention, through I 2 C Switch chip for enabling multiple pressure-sensitive sensors and baseboard management controller to pass through I 2 And C, carrying out communication interaction on the signals.
In step S703, when the male plug of the external device is plugged into the female plug of the connector, the baseboard management controller is started.
In step S704, the baseboard management controller passes through I 2 The C Switch chip acquires pressure information detected by the pressure sensors to determine the pressure value received by each elastic sheet.
In step S705, the pressure values are compared with the pressure threshold value in the baseboard management controller, respectively, to determine the plugging state between the male connector and the female connector of the external plugging device.
In step S706, if the pressure values are all greater than or equal to the pressure threshold, then it is determined that the extrapolation device is plugged in place.
In step S707, the baseboard management controller controls the voltage regulator to be in a non-power supply state, stops power supply to the pressure-sensitive sensor, and controls the color of the status light to remain green.
In step S708, if at least one pressure value is less than the pressure threshold, it is determined that the extrapolation apparatus is not plugged in place.
In step S709, the baseboard management controller controls the voltage regulator to be in a power supply state, continuously supplies power to the pressure sensor, and controls the status light to display red color.
In step S710, the plug state is reported to the server state.
Through the embodiment, the server fault problem caused by the fact that the Slimline is not plugged in place or is in poor plugging can be rapidly judged. The assembly can be confirmed through the source, so that the maintenance efficiency is improved, the efficiency of positioning the external plugging equipment in the abnormal plugging state is improved, and the improvement of the assembly efficiency of the server and the improvement of the assembly workstation is facilitated.
