Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a machine head and tail communication method, which is applied to a machine head and is shown in figure 1, and comprises the following steps:
s11: after power is on, power is supplied to the tail.
Specifically, after the machine head is powered on and initialized, equipment information needs to be acquired from the machine tail, and as the machine tail opening control is integrated in the machine head, the machine tail cannot be started before the machine head, and meanwhile, as the machine tail is not started, the machine tail is in a non-power supply state, the machine head needs to supply power to the machine tail in advance, and the machine head can acquire the related information of the machine tail.
S12: and judging whether the power supply to the tail is successful or not.
Specifically, if the tail exists, the head BMC of the head can communicate with the tail BMC in the tail, so as to determine that the power supply is successful, and if the tail does not exist or the tail BMC is not powered due to a failure, the head BMC may count as a power supply failure because no response of the tail BMC is obtained.
S13: if the starting up command is successful, judging whether the tail meets the starting up condition or not after the starting up command is received.
Specifically, if the machine head successfully supplies power to the machine tail, after the machine head receives the start-up instruction, whether the machine tail meets the start-up condition is judged, and the start-up condition may include whether the machine tail has AC power or whether the machine tail is already started up.
It should be noted that, in the embodiment of the present invention, the head only provides a small amount of power to the tail, and only can support the operation of the tail BMC in the tail, and cannot supply power to the entire tail, so that the tail needs to have a separate AC power as a power supply, and therefore, only when the tail has the AC power, there is enough power to start the tail, and only when the tail is not started, the tail can be started.
Specifically, the power-on command of the handpiece may be triggered by a user pressing a power-on key of the handpiece, or the BMC receives a corresponding digital power-on command signal. Because the corresponding boot key is also present at the tail and the priority is usually higher than that of the BMC software control, a situation that the user starts the tail in advance through the boot key of the tail may occur, and therefore, it is necessary to determine whether the tail is booted.
S14: and if the number of the tail is consistent with the number of the tail, controlling the tail to start.
Specifically, once the machine tail meets the starting condition, the machine tail is controlled to start, the machine head is controlled to control the machine tail to start, the starting time sequence of the machine tail is controlled by the machine head, and the machine tail is started after the machine head, so that the machine head can access each device in the machine tail.
S15: and after the machine tail is started, locally starting the machine.
Specifically, after the machine tail is determined to be started, the local machine head is started, so that the machine head is ensured to be started after the machine tail is started, and the problem that the machine head cannot access equipment in the machine tail due to the fact that the machine tail is started first is avoided.
Therefore, the head of the embodiment of the invention actively supplies power to the tail, so that the state of the tail can be determined, the power-on of the tail is controlled according to the state of the tail, the power-on control right of the tail is transferred to the head, the tail is ensured to be started before the head, the problem that the head cannot access the tail because the tail is started later than the head is solved, and the stability and the reliability are improved.
The embodiment of the invention discloses a specific machine head and machine tail communication method, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Referring to fig. 2, specifically:
s21: after the power is on, the power is supplied to the machine tail through the POE port connected with the machine tail.
Specifically, the aircraft nose can utilize POE (Power Over Ethernet, active Ethernet) port to the tail BMC Power supply of tail, adopts POE net gape to connect aircraft nose and tail can communicate promptly, can supply Power again, need not to set up solitary Power supply port, and the one-tenth has many, has improved the port utilization ratio, has reduced the modification to existing equipment, has improved the suitability.
S22: judging whether power supply to the tail is successful or not;
s23: if the starting command is successful, judging whether the tail has the AC power or not after receiving the starting command.
Specifically, it is determined whether an AC power (Alternating Current) exists at the tail, and if so, it may be further determined whether the tail may be powered on, and if not, the tail may not have enough power to power on.
S24: if yes, judging whether the tail is started or not;
s25: if the tail is not started, controlling the tail to start;
s26: after the machine tail is started, the machine tail is locally started;
s27: and acquiring BMC version information and FRU information of the tail.
Specifically, after the communication connection is established between the machine head BMC of the machine head and the machine tail BMC of the machine tail, the machine head BMC can also acquire BMC version information and FRU information of the machine tail, so that a user can check the BMC version information and the FRU information of the machine tail at the machine head without checking the machine tail, and the machine head BMC is more convenient and faster.
S28: and if the tail power supply fails, no AC power exists or the tail power supply is not started, feeding back an abnormal alarm.
Specifically, if it is determined that power supply fails, no AC power exists or the machine is not started in any of the determination processes of S22, S23, and S24, it is declared that the machine cannot be normally started by the machine head control machine tail, an alarm message may be generated and fed back to the user, so that the user can know the occurrence of a fault as soon as possible to perform corresponding maintenance, and the alarm message may inform the user of the possible reason of the current fault, such as no response in communication or no AC power.
Specifically, in any of the above embodiments, the head communicates with the tail based on the TPC/IP protocol, so as to ensure the security of communication and ensure the communication speed.
