Problems solved by technology
In the existing technology, the overall vehicle weight of the maglev train will change during operation. However, the current technology cannot accurately monitor the change of the overall vehicle weight during the operation of the maglev train in real time. The lack of this vehicle weight change parameter makes it impossible to Precisely monitor the full state of the maglev train, and it is impossible to accurately predict the fault

The invention discloses a monitoring method and system for the train weight of a maglev train. The method comprises the following steps: acquiring the levitation current of the maglev train in real time, inputting the levitation current into a preset train weight model for calculation, acquiring the real-time train weight of the maglev train, comparing the real-time train weight with a preset train weight threshold value, and if the real-time train weight exceeds the preset train weight threshold value, starting an alarm. According to the monitoring method and system for the train weight of themaglev train,the real-time acquired levitation current of the maglev train is input into the preset train weight model for real-time calculation, so that the real-time train weight of the maglev train is obtained, an alarm is started when the real-time train weight exceeds the preset train weight threshold value, and reliable support is provided for accurately monitoring the full state of the maglev train and accurately pre-judging faults.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and system for monitoring the vehicle weight of a maglev train. Background technique [0002] With the rapid development of major cities in our country, traffic congestion has become the primary solid disease in cities. The maglev train is a new type of transportation that uses a non-contact electromagnetic levitation, guidance and drive system. Among them, the speed of high-speed maglev trains can reach more than 500 kilometers per hour, and the speed of medium and low-speed maglev trains is between 100-160 kilometers per hour. [0003] The operating principle of the current maglev train is mainly: based on the levitation force provided by the electromagnetic force, the gravity generated by the levitation force supporting the overall weight of the maglev train makes the maglev train run smoothly on the track without contact. It can be seen that whether the levitation...
