This invention provides a fault protection method and apparatus for switching sessions of an on-board ECU, relating to the field of vehicle fault handling technology. The method includes: responding to a switching request from the on-board ECU for a target session, determining the electronic flash memory status of the on-board ECU; when the electronic flash memory status is an unlocked state allowing session switching, and the on-board ECU begins switching the target session, performing a switching verification on the session switching status according to a preset triple-permission verification rule; if the switching verification fails, suspending the switching request, and performing a risk assessment on the electronic flash memory after the on-board ECU switches to the target session, obtaining an electronic flash memory risk index; when the electronic flash memory risk index is greater than a first risk threshold, rolling back the session switching status of the on-board ECU. This invention solves the problem that the on-board ECU session switching is not linked with the EFlash, making the EFlash prone to abnormal flashing errors, and even causing safety hazards to the vehicle.

The utility model discloses an integrated cabinet body of flywheel converter, and the cabinet body is divided into power area and control area through the partition structure, at least one pull-out box is equipped in the control area, the pull-out box is used for installing the control component and is convenient for pull-out maintenance, the partition structure includes partition frame and the baffle covered and installed on the partition frame, realizes the physical isolation of power area and control area, thereby integrates power area and control area in the same cabinet body, realizes functional isolation through the baffle at the same time, greatly reduces the overall floor area, improves single cabinet space utilization, especially suitable for the scene of higher space compactness requirement such as computer lab, energy storage power station. Through the setting of pull-out box, it is convenient to directly pull out the cabinet operation, does not need to dismount fixed bolt or removes the periphery component as a whole, and maintenance time is shortened.

The utility model discloses a mounting structure of a transformer. The mounting structure comprises a transformer bottom plate for mounting the transformer and a transformer plate cover fixed on the transformer bottom plate, the transformer plate cover comprises a top plate and side plates oppositely fixed to the two sides of the top plate respectively. After the transformer is installed on the transformer bottom plate and then integrated to an air conditioner in a machine room, the risk that the transformer is possibly touched by people by mistake when being externally connected is avoided, the situation that lines of the externally-connected transformer are disordered is also avoided, maintenance personnel can rapidly position faults, the maintenance efficiency is improved, and the maintenance cost is reduced. Condensate water generated by operation of an air conditioner in a machine room and water splashing possibly occurring in complex environments such as a steel mill are fully considered, the flash is arranged to provide anti-splashing protection for the transformer, the fault probability of short circuit, burning and the like caused by water inflow is reduced, and the service life of the transformer is prolonged.

This invention relates to the field of fault data processing technology and discloses a method and system for fault diagnosis and early warning of mobile energy storage devices. The method includes: acquiring the operating data of the target energy storage object; analyzing the pre-processed real-time operating data to obtain a multi-dimensional situation field; the target energy storage object is an outdoor energy storage power source; calculating the multi-dimensional situation field to obtain the synaptic traces of abnormal data and identifying antibody modes; analyzing the stability of each antibody mode to obtain the mode confidence. This solution accurately captures the dynamic evolution characteristics of multi-parameter coupling of faults by constructing a dynamic cellular network and a multi-dimensional situation field, and achieves deep causal inference based on synaptic traces, antibody modes, and mode confidence. It locks the root cause of the fault by the root cause contribution and generates a fault early warning command by combining the fault outbreak potential energy. This can help non-professional outdoor personnel quickly locate faults and improve the accuracy of diagnosis and the timeliness of early warning.
