Abstract

The present invention discloses a fault prediction method and apparatus, and a fire fighting truck. The method comprises: analyzing all acquired data on a bus, so as to obtain each communication quality indicator used for reflecting communication quality of the bus; and determining whether each communication quality indicator is within a corresponding indicator value range, and if it is determined that at least one communication quality indicator is not within the corresponding indicator value range, determining that the bus has a fault risk, so as to predict occurrence of a bus fault, perform corresponding security processing on a bus system before the fault occurs, and avoid a risk brought by breakdown of the bus system when the fault suddenly occurs to an electrical system, thereby improving security and reliability of the electrical system.

Description

technical field

[0001] The invention relates to the field of electrical systems, in particular to a fault prediction method, device and fire truck. Background technique

[0002] For electrical systems of electrical equipment such as fire trucks, bus communication is often used to transmit signal data. That is, the data transmission in the electrical system can be realized mainly through the bus system, therefore, the reliability of the bus system has a very important impact on the performance of the electrical system.

[0003] Specifically, in order to ensure the reliable and safe operation of the bus system, the master node in the bus system can be used to detect the real-time status of other sub-nodes (such as whether it is online, whether it is normal, etc.), so as to monitor the operation of the entire bus system. If it is determined that there is a fault in a certain sub-node, and the fault of the sub-node reaches the set fault standard, then stop the data sending and ...
