Embodiment 1

[0020] Embodiment 1: as figure 1 as shown,

[0021] An EMU bogie instability detection device, the central processing unit is based on the ARM Cortex-A8 core or ARM Cortex-M4 core, with a memory of more than 128MB, rich hardware interface resources, and peripheral equipment for simulation, communication, timing and control.

[0022] In addition to the internal memory that the central processing unit has, it is also provided with a non-volatile 2GBeMMC memory that cooperates with the serial bus port.

[0023] In order to control the needs, the central processing unit leads to the output port of the digital quantity at the same time, and drives the relay to complete the external control. When the central processing unit judges that the bogie is unstable, this port can output an alarm switch signal to control the braking system.

[0024] The serial port is a standard port of the central processing unit for internal and external data communication. Communicate with the accelera...

Embodiment 2

[0027] Embodiment 2: a kind of EMU bogie instability detection device, such as figure 2 As shown, each car of the EMU is equipped with a bogie instability detection device 1; the system includes a bogie instability detection device host 2 and four acceleration sensors 3; the bogie instability detection device host 2 is connected to four Accelerometer.

[0028] The main engine of the bogie instability detection device of each carriage transmits the collected measured position instability information and sensor status to the corresponding network control device of each carriage, and the entire train under test can be monitored in real time on the monitoring screen of the train network Positional instability information and sensor status.

Embodiment 3

[0030] Such as image 3 , Figure 4 As shown, the power supply unit POWER provides power for each unit of the main engine of the bogie instability detection device and the acceleration sensor. The power supply for each unit adopts the design of DC100 to DC24V input and output isolation power supply, and the power supply for the acceleration sensor adopts DC100 to DC12V input and output isolation power supply Design; the power supply supports 70Vdc ~ 137.5Vdc input voltage, with power reverse connection, overvoltage and overcurrent protection.

[0031] The data acquisition unit can collect 4-way acceleration sensor information, and supports acceleration sensors with 4-20mA current interface.

[0032] The system control unit is the central processing unit, which processes the collected data, outputs it to the vehicle network on the one hand, and stores it locally on the other hand.

[0033] The host of the bogie instability detection system includes a power supply unit POWER, ...

Abstract

The invention provides a motor train unit bogie instability detection device and a realization method and belongs to the technical field of motor train unit control. The realization method comprises the following steps: a central processing unit is connected with an acceleration sensor by a 4-20mA current interface to obtain acceleration change information of the acceleration sensor at a detected position; a working state and instability information of the sensor are output through a current ring or an MVB interface after a filtering algorithm and instability judgment are carried out; a switching value instability signal is output by an IO port; and meanwhile, recorded data are stored in a data storage device. According to the motor train unit bogie instability detection device, acceleration information of the detected position can be fed back in real time so that the controllability and the operability are improved, misinformation can be further prevented and the train safety is improved.

Description

technical field [0001] The invention relates to a bogie instability detection device and a realization method of an EMU, and belongs to the technical field of EMU control. Background technique [0002] In the original EMU, the bogie instability detection device is to warn the driver when the bogie has abnormal vibration in the horizontal direction that may cause derailment. When the bogie vibrates abnormally, the warning light on the driver's console will light up. On the display screen of the vehicle information control device on the driver's station, the bogie abnormality and equipment failure are prompted, and the acceleration sensor abnormality and the location of the abnormal sensor are prompted. [0003] The original EMU installation products are all imported, and it is impossible to adjust the instability parameters in a timely manner according to the current environment of my country's EMU operating lines. [0004] With the rapid development of my country's high-sp...
