In a fifth embodiment of the IPMC remote control debugging method based on VPX system according to the present invention, based on the third embodiment, step S110 includes the following steps:
step S510: and judging whether the first dispersion is larger than the first preset value or not.
Specifically, the upper computer judges whether the first dispersion is greater than the first preset value.
If yes, go to step S520: and generating remote configuration information through the CHMC module according to the debugging instruction, wherein the remote configuration information comprises a program replacing instruction.
Specifically, if the first dispersion is greater than the first preset value, it indicates that the temperature of the service chip is abnormal, and the temperature of the service chip is abnormal, which is usually caused by a high-load operation of the service chip or a bug occurring in a program running on the service chip, so that a cured program in the service chip needs to be replaced to avoid the abnormality of the service chip.
Step S140, including the steps of:
step S530: and acquiring a standby program through the upper computer based on the program replacing instruction.
Specifically, the standby program is a program for replacing the curing program in the service chip, and the functions of the standby program are consistent with those of the curing program.
Step S540: sending, by the CHMC module, the standby program to the IPMC module.
Step S550: and burning the standby program into the service chip through the IPMC module and the JTAG port so as to cover the curing program in the service chip.
The embodiment has the effect that when the first dispersion is greater than the first preset value, it indicates that the temperature of the service chip is abnormal, and the abnormal temperature of the service chip is usually caused by a leak in the solidified program in the service chip, so that the standby program is burned into the service chip and replaces the previous solidified program, so as to solve the problem that the temperature of the service chip is abnormal.
In a sixth embodiment of the IPMC remote control debugging method based on VPX system according to the present invention, based on the fifth embodiment, step S510 further includes the following steps:

Step S140, including the steps of:
step S620: and controlling the VPX board card to restart through the IPMC module and the JTAG port based on the restart instruction.
Specifically, if the first dispersion is not greater than the first preset value and the VPX board is abnormal in operation, it indicates that the second dispersion is greater than the second preset value, or the third dispersion is greater than the third preset value, that is, the operating voltage or the operating current of the service chip is abnormal, which is usually caused by a defect in the hardware design of the VPX board and is irrelevant to software, so that the problem can be solved by directly restarting the VPX board.
In a seventh embodiment of the IPMC remote control debugging method based on VPX system according to the present invention, based on the fifth embodiment, step S510 further includes the following steps:
if yes, go to step S710: and acquiring each moment when the actual temperature curve is greater than the preset temperature curve, and marking as an abnormal moment.
Specifically, if yes, the upper computer acquires each moment when the actual temperature curve is greater than the preset temperature curve, and marks the moment as an abnormal moment.
Step S720: and acquiring the running code segment of the solidified program at the abnormal moment.
Specifically, the upper computer acquires an operation code segment of the solidified program at the abnormal moment, wherein the operation code segment is an operation code segment corresponding to the abnormal moment of the temperature of the service chip, and the reason why the temperature of the service chip is abnormal can be intuitively reflected.
Step S730: and displaying the running code segment of the solidified program through the upper computer.
The purpose of this embodiment is to visually display the running code segment corresponding to the time when the temperature of the service chip is abnormal, so that the worker can find the code segment causing the temperature abnormality of the service chip in the curing program, and repair the code segment to avoid the occurrence of such abnormal operation again.
In an eighth embodiment of the IPMC remote control debugging method based on VPX system according to the present invention, based on the second embodiment, step S240 further includes the following steps:
if yes, go to step S810: and acquiring the model code of the VPX board card with abnormal work, and marking the model code as an abnormal number.
Specifically, the upper computer acquires the model code of the VPX board card with abnormal work and marks the model code as an abnormal number; each VPX board card is correspondingly provided with a model number, and the model numbers of the VPX board cards with the same hardware design (such as the circuit design of the VPX board cards) are consistent.
Step S820: and acquiring all the VPX board cards with the same abnormal type number, and marking the VPX board cards as a first board card set.
Specifically, the upper computer acquires all the VPX board cards with the same abnormal type number, and marks the VPX board cards as a first board card set. The first board card set is a set of VPX board cards with the same hardware design.
Step S830: and acquiring the VPX board cards with different curing programs in the service chip in the first board card set, and marking the VPX board cards as a second board card set.
Specifically, the upper computer acquires the VPX board card with different curing programs in the service chip from the first board card set, and marks the VPX board card with the different curing programs as a second board card set. That is, the second board card set is a set of VPX board cards in which the curing programs of the service chips are different from each other in the first board card set, that is, a set of VPX board cards in different practical applications in a set of VPX board cards with the same hardware design.
Step S840: and calculating the occupation ratio value of the VPX board card with abnormal work in the second board card set.
Specifically, the upper computer calculates the duty ratio of the VPX board in the second board set, where the working abnormality occurs, and it is noted that the working abnormality here refers to a corresponding working abnormality when the second dispersion is greater than the second preset value, or the third dispersion is greater than the third preset value (the working abnormality in this case is usually caused by a hardware design defect of the VPX board).
Step S850: and judging whether the ratio is larger than a preset ratio or not.
Specifically, the upper computer determines whether the ratio is greater than a preset ratio (preferably 40%).
If yes, go to step S860: and generating and displaying first feedback information, wherein the first feedback information is used for expressing that the VPX board card has hardware design defects.
Specifically, if the second board card is centralized, the percentage of the VPX board cards with abnormal operation exceeds 40%, which indicates that the VPX board cards with the same hardware design have a higher probability of abnormal operation, thereby determining that the hardware design of the VPX board cards is indeed defective.
