High-pressure and high-pressure Safety Monitoring Safety Monitoring System

The invention discloses a high voltage safety monitoring method and a safety monitoring system. The high voltage safety monitoring method comprises steps of receiving monitoring information of all high voltage members which is transmitted through a bus, wherein the monitoring information comprises effective voltage of corresponding voltage members, performing comparison on the basis of effective voltage of all the high voltage members and the voltage of the power battery, performing early warning according to the comparison result, and if needed, transmitting early warning information. The implementation scheme of the invention can perform early warning on the basis of comparison result between the effective voltage of various high voltage members and the voltage of the power battery, which can eliminate the safety hazard of the electric automobiles or other devices with the high voltage systems, avoids the high voltage safety fault accident and greatly improves the safety of the electric automobile or other device with the high voltage systems.
