Embodiment 1

[0024] In order to solve the problem that the electrical system is paralyzed due to the sudden stop of the bus system, which reduces the safety and reliability of the electrical system, Embodiment 1 of the present invention provides a fault prediction method, such as figure 1 As shown, it is a schematic flow chart of the fault prediction method described in Embodiment 1 of the present invention, specifically, as figure 1 As shown, the method may include the following steps:

[0025] Step 101: collecting all data on the bus, and obtaining various communication quality indicators for reflecting the communication quality of the bus according to the collected data;

[0026] Step 102: For each communication quality index, according to the set index value range corresponding to the communication quality index, determine whether the communication quality index is within the corresponding index value range;

[0027] Step 103: If it is determined that at least one communication qualit...

Embodiment 2

[0056] Based on the same inventive concept as that of Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a fault prediction device, such as image 3 As shown in , it is a schematic structural diagram of the fault prediction device described in Embodiment 2 of the present invention, specifically, as image 3 As shown, the failure prediction device may include:

[0057] The data collection module 31 is used to collect all data on the bus, and obtains various communication quality indicators for reflecting the communication quality of the bus according to the collected data;

[0058] The indicator judging module 32 is configured to, for each communication quality indicator, judge whether the communication quality indicator is within the corresponding indicator value range according to the set indicator value range corresponding to the communication quality indicator;

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 ...
