Embodiment Construction

[0017] The micromechanical destabilizing acceleration sensor of the present invention is composed of four parts: a biaxial accelerometer, a power conversion circuit, an acquisition processing circuit and a current output circuit. The embodiments will be further described below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the biaxial accelerometer 1 is sensitive to the lateral and longitudinal acceleration information during the running of the train, and sends the measurement results to the acquisition and processing circuit 3 . The acquisition and processing circuit 3 sends it to the current output circuit 4 after processing. The current output circuit 4 converts the data into a current signal and sends it to the train instability monitoring system to monitor the running state of the train in real time. The power conversion circuit 2 provides the required power for the biaxial accelerometer 1, the acquisition processing circuit 3, the current...

Abstract

The invention discloses a micro-mechanical instability acceleration sensor, and belongs to the technical field of rail transit. The micro-mechanical instability acceleration sensor is composed of a biaxial accelerometer, a power conversion circuit, an acquisition processing circuit and a current output circuit. When the system is used in a train instability monitoring system, the accuracy of train transverse and longitudinal acceleration measurement can be effectively improved, and meanwhile the system has the advantages of being high in real-time performance, simple in circuit structure, small in size, flexible to install, high in cost performance, low in power consumption, high in anti-jamming capability and the like.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a micromechanical instability acceleration sensor. Background technique [0002] The acceleration sensor is an important component in the train real-time monitoring system. It is installed in multiple key positions of the high-speed train and is used to sensitive the acceleration information in different directions during the operation of the train. The on-board real-time monitoring system can effectively control the driving status by analyzing the sensor data. [0003] Under certain operating conditions, high-speed trains may experience serpentine instability, which may lead to rail climbing or even derailment accidents in severe cases. Therefore, high-speed trains must use acceleration sensors installed on the bogie to monitor serpentine instability in order to detect problems in advance. Improve the reliability and safety of high-speed train operation. The ac...
