The present application provides a method, apparatus, storage medium, and computer device for determining the cause of an accident. The method includes: in the event of an accident involving an autonomous vehicle, using hardware device detection data and software module result data corresponding to the accident investigation period as accident data; for each investigation moment in the accident investigation period, determining the hardware fault and software fault existing in the autonomous vehicle at that investigation moment based on the hardware device detection data and software module result data, respectively, to obtain hardware fault information and software fault information corresponding to that investigation moment; determining the critical moment of the accident from each investigation moment based on each investigation moment, the hardware fault information corresponding to each investigation moment, and the software fault information corresponding to each investigation moment; and using the critical moment of the accident to locate the time when the fault causing the accident occurred. The method of the present application can improve the efficiency of analyzing the cause of the accident.

Even in the event of a software malfunction that prevents start-up, the malfunction can be addressed without replacing a control unit of a display device. A work machine (1) is provided with a bird's-eye view image display device (20), which is an example of a display device. This bird's-eye view image display device comprises a monitor (22) for bird's-eye view images and a calculation unit (21) for screen display, and the calculation unit for screen display is provided with a first processing unit (211) for controlling a screen display function and a second processing unit (212) for controlling a predetermined function other than the screen display function. The second processing unit issues a notification of a malfunction to a work machine control unit (10), which is an example of another type of equipment, when the first processing unit has malfunctioned, and causes the first processing unit to transition to a recovery mode when an indication is received from the work machine control unit that indicates a transition to a recovery mode in which software recovery is achievable by an external storage medium (40).

This invention discloses a hardware fault control method and system based on a motor controller. The method includes configuring a hardware fault signal as an interrupt trigger input for the microcontroller; after system power-on initialization, resetting the driver chip and then enabling the hardware latch circuit, which latches the hardware fault signal and outputs a total hardware fault signal; monitoring the hardware fault signal, and when the trigger edge of the hardware fault pin is interrupted, determining whether the current motor state meets preset conditions; if the conditions are met, setting the corresponding software fault flag; acquiring the software fault flag and the total hardware fault signal output by the hardware latch circuit, and combining this with whether the motor is currently under high-voltage power-on, performing fault diagnosis and corresponding protection and recovery operations. This invention solves the technical problems of slow hardware fault diagnosis response speed, easy false alarms during power-on, and limited fault recovery strategies in existing technologies.

The invention discloses a hardware priority arbitration and selection circuit for fire control, which comprises a mode selection unit used for outputting levels representing different working modes according to user operation, and a priority arbitration unit used for physically switching a control path on a hardware level according to a level signal, mode priority setting is realized on hardware; the driving output unit is used for driving an external fire-fighting executing mechanism; and the state feedback unit is used for feeding back the state of the actually gated control path to the control chip in real time so as to realize mode visualization and event recording. Mode priority arbitration is achieved in a pure hardware mode, and misoperation caused by software faults is avoided; the arbitrated signal enters a power driving link, so that delay and interference are reduced, and the action reliability of an execution mechanism is improved; the state feedback unit is independent of user input so as to ensure that the system can accurately obtain the actual operation state, and the overall safety level of the fire control system is improved.

The invention relates to an industrial personal computer repair decision-making method based on an operating environment and a related device. The method comprises the following steps: acquiring working condition data of an industrial personal computer, and if the working condition data does not meet an operation condition matched with a current environment, performing fault analysis on the working condition data to obtain a hardware fault analysis result and a software fault analysis result; if only one of the hardware fault analysis result and the software fault analysis result is judged to be a fault establishment item, a repair suggestion is provided on an independent level according to operation influence characteristics of the fault establishment item in the current environment; if the hardware fault analysis result and the software fault analysis result are judged to be fault establishment items, according to the failure coupling relation between the two types of fault establishment items in the current environment, a repair suggestion is provided on the joint level. By adopting the method, the self-adaptive selection of the repair decision path can be realized, and the repair suggestion is kept consistent with the actual operation state, so that the pertinence and the accuracy of the repair decision are effectively improved.
