The structure, function, and implementation process of the safety monitoring system and the high-speed EMU provided by this embodiment will be described with examples below in conjunction with the accompanying drawings.

Please refer to Figures 1 to 5, Figure 2 shows only part of the vehicle monitoring system. The high-speed EMU provided in this embodiment includes: multiple vehicles connected in sequence and a safety monitoring system, and the monitoring system is installed on the vehicle. The vehicle has a vehicle body and a bogie arranged at the bottom end of the vehicle body.

For example, the composite sensor 11 includes: a temperature sensor, a vibration and shock sensitive device, a shear base, a conductive circuit board, and a conditioner. One end of the temperature sensor along its axial direction is provided with a coaxial and annular shear seat; the radial inner side of the shear seat is provided with a conductive circuit board coaxial with the temperature sensor, and the temperature sensor is electrically connected to the conductive circuit board; One end of the circuit board is provided with a coaxial vibration and shock sensitive device, the vibration and shock sensitive device is made of Athens material, and the outer circumferential surface of the vibration and shock sensitive device is in contact with the inner circumferential surface of the shear seat. The composite sensor 11 may also include a housing for protecting the temperature sensor and vibration and shock sensitive devices therein, and the conditioner may be arranged in the housing.

Among them, the conductive circuit board is used to output the temperature signal of the temperature sensor. When the monitored part vibrates, the vibration will be transmitted to the vibration and shock sensitive device. The vibration and shock sensitive device generates a high-resistance charge signal through the shearing action of the shear seat. The charge signal is input to the conditioner through differential input, and the conditioner is used to transfer it. Converted into a low-impedance voltage signal, that is, a vibration signal for output.

The detection component 1 may further include a pre-processor 12; the composite sensor 11 is electrically connected to the pre-processor 12, and the pre-processor 12 is used to process and send the detection signal of the composite sensor 11 To the monitoring host 2. Among them, the detection signal of the composite sensor 11 includes a temperature signal and a vibration signal; the preprocessor 12 is used to integrate the detection signal of the composite sensor 11 and send it to the monitoring host 2.

The bogie can be provided with multiple composite sensors 11, and multiple composite sensors 11 of the same bogie can be electrically connected to the same preprocessor 12, so as to facilitate both the cost of the safety monitoring system and the efficiency of data processing. Of course, an independent preprocessor 12 can also be provided for each composite sensor 11; or, multiple composite sensors 11 of the same vehicle can be electrically connected to the same preprocessor 12.

The bogie has a frame and an axle box, a gear box, and a traction motor mounted to the frame, and the axle box, the gear box, and the traction motor are respectively provided with at least one composite sensor 11. Exemplarily, the traction motor has a driving end and a non-driving end, and the driving end and the non-driving end are respectively provided with at least one composite sensor 11. Wherein, the composite sensor 11 can be arranged on the rotating part, or arranged at a position that cooperates with the rotating part; for example, the composite sensor 11 can be arranged at a bearing.

The gear box includes a large gear and a small gear, and at least one composite sensor 11 is respectively provided at the large gear and the small gear. For example, multiple composite sensors 11 are provided at the large gear and the small gear respectively; part of the composite sensor 11 can be provided on the corresponding gear, and the other half of the composite sensor 11 can be provided on the matching bearing. Of course, a composite sensor 11 is provided at the big gear and the small gear respectively, and the composite sensor 11 can be arranged on a bearing matched with the gear.

This embodiment is just an example here, and it can be specifically set according to actual needs.

After the preprocessor 12 sends the detection signal of the composite sensor 11 to the monitoring host 2, the monitoring host 2 is used to compare the detection signal with the corresponding standard value, and determine the corresponding composite sensor if the temperature or vibration exceeds the standard value 11 is in an abnormal state. The comparison process is the diagnosis of the corresponding components.

When it is determined that the location of the corresponding composite sensor 11 is in an abnormal state, the monitoring host 2 generates corresponding diagnostic information to indicate that the temperature or vibration of the corresponding location is in an abnormal state and sends it to the train-level network 3, which is sent to the train management by the train-level network 3 And control system TCMS4. The train management and control system TCMS4 can be used to control high-speed EMUs to decelerate or stop based on the diagnostic information; and/or the train management and control system TCMS4 can be used to control the man-machine interface HMI in the man-machine cab based on the diagnostic information to display. This enables the train driver in the driver's cab to learn about the abnormal situation in time.

In the specific implementation process, the train management and control system TCMS4 can be used to perform hierarchical warnings based on the diagnostic information. For example, early warning and grading alarms can be carried out according to the severity. In the early warning, TCMS4 can be used to control the human-machine interface HMI in the driver's cab to display according to the diagnostic information, so that the train driver in the driver's cab can learn about the abnormal situation in the early stage in time, so that the train driver can take corresponding measures according to the actual situation. Such as controlling the deceleration of high-speed EMUs.

When the severity is low, TCMS4 can be used to control the human-machine interface HMI in the driver's cab to display according to the diagnostic information, so that the train driver in the driver's cab can learn about abnormal conditions with a low severity in time, and control and control high-speed EMUs Slow down to facilitate relief. When the severity is high, TCMS4 can be used to control the man-machine interface HMI in the driver's cab to display according to the diagnostic information, so that the train driver in the driver's cab can timely understand the abnormal situation with high severity and control the high-speed EMU Stop to help ensure the safety of passengers and trains.

Of course, the implementation process of the train management and control system TCMS4 that can be used for warning based on the diagnostic information is not limited to this, and this embodiment is just an example here, and the details may be determined according to actual conditions.

In this example, by installing temperature/vibration composite sensors 11 at the bearings of the axle box, gear box, and traction motor, the temperature and vibration and shock signals of each component can be monitored, so as to evaluate the status of rotating components in real time, which is conducive to the reliability of train operation.

In one of the possible implementation manners, the detection component 1 includes: an instability detection sensor 13, an anti-derailment vibration sensor 14 and a vehicle body stability detection sensor 15; an instability detection sensor 13, an anti-derailment vibration sensor 14 and a vehicle body The body stability detection sensor 15 is electrically connected to the monitoring host 2 to send a detection signal to the monitoring host 2.

The instability detection sensor 13 and the anti-derailment vibration sensor 14 are installed on the bogie. The instability detection sensor 13 is used to detect the stability of the bogie. The anti-derailment vibration sensor 14 is used to detect whether the train is derailed. The vehicle body stability detection sensor 15 is provided on the vehicle body for detecting the stability of the vehicle body. Among them, the structure and implementation process of the instability detection sensor 13, the anti-derailment vibration sensor 14, and the vehicle body stability detection sensor 15 can adopt conventional settings in the field, and this embodiment is not specifically limited here.

Exemplarily, the instability detection sensor 13 includes an acceleration sensor, and the lateral acceleration of the frame monitored by the acceleration sensor in real time reflects the lateral stability of the bogie. When the train is derailed, a certain derailment load is formed between the bogie and the track. The vertical load in the derailment load will cause the upper end of the vertical damping spring to move upwards, so that the spring member produces a moving deformation, so that it can pass the detection The deformation amount of the spring is used to monitor whether the derailment is derailed; accordingly, the anti-derailment vibration sensor 14 may include a deformation sensor for detecting the deformation of the spring.

The vehicle body stability detection sensor 15 may include an acceleration sensor, and the acceleration of the vehicle body is detected in real time by the acceleration sensor to reflect the stability of the vehicle body. There may be multiple vehicle body stability detection sensors 15 and they are arranged at the bottom of the vehicle body. As shown in FIG. 5, a plurality of vehicle body stability detection sensors 15 may be symmetrically arranged _{with respect to the longitudinal center line Y c of the} vehicle body and the lateral center line X _c. A plurality of vehicle body stability detection sensors 15 are respectively arranged in the area of the vehicle body corresponding to the bogie, and the plurality of vehicle body stability detection sensors 15 are respectively located on the opposite side of the _{two bogie center lines X z at the bottom of the vehicle body.}

When the monitoring host 2 receives the detection signals of the instability detection sensor 13, the anti-derailment vibration sensor 14, and the vehicle body stability detection sensor 15, the corresponding detection value is compared with the corresponding standard value. If the detection value exceeds the standard Value, it is determined that the corresponding component of the high-speed EMU is abnormal. For example, when the detection value of the instability detection sensor 13 exceeds the standard value, it is determined that the lateral stability of the bogie is poor; when the detection value of the anti-derailment vibration sensor 14 exceeds the standard value, it is determined that the train is derailed; when determining the stability of the car body When the detection value of the detection sensor 15 exceeds the standard value, it is determined that the stability of the vehicle body is poor.

When it is determined that the location of the instability detection sensor 13, the anti-derailment vibration sensor 14, or the vehicle body stability detection sensor 15 is in an abnormal state, the monitoring host 2 generates the corresponding diagnostic information to indicate that the temperature or vibration of the corresponding location is in an abnormal state. To the train-level network 3, the train-level network 3 sends to the train management and control system TCMS4. The train management and control system TCMS4 can be used to control high-speed EMUs to decelerate or stop based on the diagnostic information; and/or the train management and control system TCMS4 can be used to control the man-machine interface HMI in the man-machine cab based on the diagnostic information to display. This enables the train driver in the driver's cab to learn about the abnormal situation in time.

In the specific implementation process, the train management and control system TCMS4 can be used to perform hierarchical warnings based on the diagnostic information. For example, early warning and grading alarms can be carried out according to the severity. The specific implementation process may be similar to the foregoing implementation process of the diagnostic information generated based on the detection signal of the composite sensor 11, and will not be repeated here in this embodiment.

In this example, the safety monitoring system has the function of real-time monitoring and control of key components such as frame instability, car body stability, derailment prevention, and rotating parts, which can further facilitate the reliability of train operation.

Among them, time, speed, operating mileage, working conditions of key train systems and driver control, etc.; key train systems include EMU traction system, braking system, etc.

The monitoring host 2 can establish a vehicle operating state identification model based on the timing and phase relationship of the vibration acceleration signal in the detection signal of the detection component 1, and based on the public information obtained from TCMS4, real-time monitoring of the reliability of the EMU operation.

The monitoring host 2 can detect and diagnose the temperature and vibration of bearings, gearboxes, traction motors, train derailment, structural instability, car body stability and other components and safety factors in real time based on the above-mentioned public information and the detection information of detection component 1. Diagnose the emergency information, evolution information and large-capacity information of EMUs, and monitor the abnormal conditions during train operation in real time. When the detected value exceeds the normal control index, that is, the standard value, the alarm can be issued and the EMU can be controlled through TCMS4 The group adopts fault-oriented safety measures such as speed reduction or parking to ensure the safe operation of the EMU.

In addition, the safety monitoring system also has a real-time database for recording the detection signals of the detection component 1 and the diagnosis results of the monitoring host 2, to facilitate the horizontal comparison of EMU monitoring data and the vertical comparison of historical data, and further facilitate the comprehensive diagnosis of the EMU.
