The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Some embodiments of the present invention provide a method for controlling power down of a VPX chassis, referring to fig. 1, including:
110, acquiring a data storage signal sent by a power-off key of the VPX case;
120, storing the current operating system data according to the data storage signal, and generating a first trigger signal;
130, generating a down electric signal according to the first trigger signal;
140, the power module of the VPX chassis is powered down.
In an exemplary embodiment, the method is implemented by a switch board on a VPX chassis, and when a power-down key on the VPX chassis is pressed, a changed level signal, that is, a data saving signal is generated, and the switch board starts a complete safe power-down process by acquiring the data saving signal. The exchange board firstly stores the data of the operating system which is currently running and generates a first trigger signal, wherein the first trigger signal is used for indicating that the storage of the operating system is successful or failed. Then, according to the first trigger signal, the switch board judges whether to send a power-off signal to the power module, the power module of the VPX chassis is powered off when receiving the power-off signal, and the power-off in this application is specifically that the power module of the VPX chassis stops supplying power to the blade type board card.
Some embodiments, generating the following electrical signal in response to the first trigger signal, include: and if the first trigger signal is detected, sending a down electric signal.
For example, when the data of the operating system is successfully stored, the switch board may generate a first trigger signal, and according to the detected first trigger signal, the switch board may send a power-off signal to the power module, and after the power module receives the power-off signal, the power module may perform a power-off operation to stop supplying power to the blade board card. If the operation data is not successfully stored, the switch board will not generate the first trigger signal.
Some embodiments, generating the lower electrical signal in response to the first trigger signal, further comprises: and if the first trigger signal is not detected within the preset time, sending a down electric signal after the preset time.
For example, if a fault occurs while the operating system data is saved, the switch board does not generate the first trigger signal, and at this time, the switch board does not send a power-down signal to the power supply module, and the power supply module does not power down. At this time, the exchange board continuously detects whether the first trigger signal is generated at preset time intervals in a preset time period. For example, the preset time is 10 seconds, if the exchange board gets rid of the fault within 10 seconds, the first trigger signal is generated and detected, at this time, the exchange board sends a power-off signal to the power module, and the power module immediately starts to power off; if the waiting time exceeds 10 seconds, the exchange board still does not detect the first trigger signal, at the moment, the exchange board still sends a power-off signal, the power supply module is controlled to start power-off, the power-off operation is completed, and the situation that power cannot be turned off due to system faults is prevented. The frequency of the first trigger signal detected by the switch board is detected once every 100 milliseconds, namely 100 times within 10 seconds, and the preset time period and the detection time interval can be set arbitrarily according to requirements.
Some embodiments, referring to fig. 2, the present invention provides a VPX chassis power-down control circuit, including: the power-off key 210 is used for sending a data storage signal, the switch board 230 is used for connecting the power-off key 210, storing current operating system data according to the data storage signal, generating a first trigger signal, and generating a power-off signal according to the first trigger signal, the power module 220 is connected to the switch board 230, and is used for receiving the power-off signal, and the power-off signal is used for controlling the power module 220 to be powered off, and the switch board 230 is used for executing the power-off control method of the VPX chassis in the above embodiment.

For example, fig. 2 includes a first service board 241, a second service board 242, and an nth service board 243, where each service board is connected to the switch board 230 through an IPMB bus, and configured to send a second trigger signal to the service board. The power-down key 210 is electrically connected to the switch board 230 and each service board for transmitting a level signal.

In some embodiments, a service panel comprises: the system comprises a service processor and a module management controller, wherein the service processor is used for storing the data of the current operating system and obtaining a second trigger signal, the module management controller is connected with the service processor and the case management controller, and the module management controller is used for sending the second trigger signal.
The operation of the electrical control circuit under the VPX chassis is described in detail below in a specific embodiment. Referring to fig. 3, when the VPX chassis is in a power-on operation state and the power-off key 210 is pressed, one end of the key is set to be grounded, the data storage signal received by the chassis management controller and the module management controller changes to a low level, and the chassis management controller and the module management controller, after receiving the low level signal, send the data storage signal to the chassis processor and the service processor, notify the chassis processor and the service processor to trigger a system to interrupt operation according to the data storage signal, and start to store operating system data. When the operating system data of the chassis processor is successfully stored, the chassis processor sends a successful storage signal, namely a first trigger signal, to the chassis management controller to notify the chassis management controller that the operating system data is successfully stored, when the operating system data of the service processor is successfully stored, the service processor sends a successful storage signal, namely a second trigger signal, to the chassis management controller, the chassis management controller judges whether the system data storage is completely finished according to the received first trigger signal and the received second trigger signal, and if the system data storage is completely finished, the chassis management controller sends a power-off signal to control the power module 220 to be powered off. If any board card in the service board and the switch board does not successfully store the operating system data, the chassis management controller can judge whether the delay time exceeds 10 seconds, if not, the chassis management controller delays for 100 milliseconds and then judges whether all the board cards complete data storage, and when the total delay time exceeds 10 seconds, the chassis management controller sends a power-off signal to the power module 220 to control the power module to power off.

For example, one end of the power switch is connected to a 12V load power supply, and the other end of the power switch respectively supplies power to the switch board 230 and the service board. The power supply controller is used for detecting whether the chassis management controller sends a power-off signal or not, and when the power-off signal is detected, the power supply switch is controlled to be switched off, the 12V load power supply output is cut off, and safe power off is completed.
