Technical Field

[0001] The present application relates to the field of railway switch machine application and detection technology, and in particular to a switch machine contact device and detection system for real-time status detection. Background Art

[0002] The switch contact device is used in railway turnout switching equipment. It is a specific actuator for railway turnout control, used to switch and lock the point rail and heart rail of the turnout, and to indicate and monitor the position and status of the turnout in the track interlocking area to ensure that the train can switch between different tracks safely and accurately.

[0003] The existing switch machine can indicate the position state and engagement state of the turnout through the state of the contact device; however, the engagement process of the contact device is relatively rapid, and it can be regarded as a result quantity with only two states, open and closed. It is impossible to obtain the data information of the contact device during the specific changes of turnout unlocking, switching, and passing.

[0004] With respect to the above-mentioned related technologies, the inventors believe that under the existing scheme of only obtaining the switch status results of the turnout, it is impossible to obtain process data when a partial fault occurs in the switch machine, and there is a lack of fault analysis dimension. There is also a lack of data monitoring breadth during turnout conversion and driving. Therefore, it is necessary to increase the monitoring dimension of the switch machine. Summary of the invention

[0005] In order to improve the detection accuracy of the switch machine and obtain the overall internal condition of the switch machine in real time, the present invention provides a switch machine contact device and a detection system for real-time status detection.

[0007] By adopting the above technical solution, an additional set of auxiliary static contacts and auxiliary moving contacts are provided in addition to the traditional multiple sets of moving contacts and static contacts, and fixed resistors are connected on both sides of the two. The fixed resistors are large resistors, and almost no current flows when the auxiliary moving contacts and the auxiliary static contacts are engaged. Therefore, when the auxiliary moving contacts and the auxiliary static contacts are used for measurement, the angle sensors provided thereon are not directly affected by the current, and the accuracy is relatively high. Moreover, the angle sensor is used to directly measure the rotation angle of the auxiliary moving contact. This measurement method is not affected by high and low temperatures, dust and oil inside the switch machine, and further reduces measurement interference factors and improves accuracy. Angle sensors are used to directly measure the rotation angle of the auxiliary moving contact, and the relationship between the rotation angle and time is reflected in real time during the turnout reverse positioning process. Specifically, it can be refined to each train passing period and each turnout track change, providing data support for subsequent status analysis and fault diagnosis, and laying the foundation for the future development direction of digital twins. In addition, the above scheme is also provided with a camera. In actual application, the camera should use a smart camera with LED fill light function. The camera uploads the captured image, and the technician cooperates with the detection data of the above angle sensor.

The length sensor cooperates with the angle sensor to measure the extended length of the action rod when the action rod of the contact device is extended to pull the point rail to change the track guide. The structural stability inside the contact device is judged by measuring the correlation between the extended length of the action rod and the rotation angle of the auxiliary moving contact.

[0012] Optionally, the main control processor is internally integrated with a numerical processing unit and a picture analysis unit; The numerical processing unit is connected to the information detection module, receives three sets of numerical information of angle value, vibration value and length value of the information detection module, and sends and generates corresponding instructions according to the numerical information; The picture analysis unit receives the picture recognition result of the information detection module, and generates and sends corresponding instructions according to the recognition result; Accordingly, the information detection module includes a value acquisition unit and a picture acquisition unit; The numerical value acquisition unit is connected to the angle sensor, the vibration sensor, and the length sensor, and sends the numerical results of the angle sensor, the vibration sensor, and the length sensor to the numerical value processing unit; The image acquisition unit is connected to the camera and sends the image information captured by the camera to the image analysis unit.

[0013] By adopting the above technical solution, the parts corresponding to the screen and value collection in the main control processor are grouped according to function, and the corresponding information detection modules are grouped according to the carrier of the collected information, thereby optimizing the information processing logic inside the main control processor; Specifically, the numerical acquisition unit inside the information detection module is used to detect numerical information and is connected to the angle sensor, vibration sensor, and length sensor; the image analysis unit is connected to the above-mentioned camera to receive the image of the camera; and the numerical acquisition unit sends the numerical information to the numerical processing unit inside the main control processor, and the image analysis unit sends the image information to the above-mentioned image analysis unit to realize group processing of comprehensive information.

[0015] By adopting the above technical solution, since there are multiple switching points on a rail, and a switch is usually set up with a switching point corresponding to each rail, it is necessary to set up multiple switch detection systems corresponding to each switch. Therefore, a collection extension and a host computer are set up to regionalize the detection systems of multiple switch machines, so that technicians can read data intuitively; Specifically, the host computer can be regarded as a regional whole machine, which is used to aggregate the information of the main control processors in the region or at all switches on a track; and considering the total amount of data transmission and the transmission bandwidth limitation, the acquisition extension is used for data diversion transmission, which can be regarded as setting an intermediate transmission node between the host computer and the switch machine. The acquisition extension corresponds to a centralized area and is used to aggregate the information of all switch machines in the centralized area; It is recommended to use a switch as the collection extension and a storage server as the host computer.

[0016] Optionally, it also includes a wireless module and a traffic detection module; The wireless module is arranged in the main control processor, the acquisition extension, and the host computer, and is connected to the main control processor, the acquisition extension corresponding to the main control processor, and the host computer corresponding to the acquisition extension; The wireless module is provided with a 4 / 5G communication module, the main control processor is pre-stored with a clock instruction file, operates at a preset cycle, retrieves the train timetable through the network, and the main control processor runs the information detection module according to the train timetable; The passage detection module is arranged on both sides of the track of the main control processor to detect the movement of the vehicle.

[0019] By adopting the above technical solution, the integrity of data transmission can also be ensured by using traditional cable transmission, that is, by using common ADSL transmission. Compared with wireless transmission, ADSL transmission has the advantages of higher transmission stability and less distortion of signal transmission, which can further ensure the integrity and accuracy of the above signal transmission. In practical applications, both wireless transmission and ADSL transmission can be used. Wireless transmission can be used for short-distance transmission without complicated and additional wiring.

The switch assembly includes a meshing gear and a rack, the rack is slidably arranged, and the gear is concentrically fixed to the end of the output shaft of the driving motor 11; an action rod 13 is fixed to one end of the rack, and the action rod 13 is horizontally arranged, and its end away from the rack is fixed to the rail point rail part, and the output shaft of the driving motor 11 is forward and reversed, driving the rack to slide in two directions, and guiding the reversal of the rail point rail. Example

[0030] The second embodiment of the present application discloses a switch machine contact device for real-time status detection, which is applied to a common switch machine in the first embodiment. Figure 1 and Figure 2 A switch machine contact device for real-time status monitoring includes two rows of moving contacts 122 and four rows of static contacts 121 that are evenly and symmetrically arranged on both sides of the rotating shaft of a driving motor 11. The moving contacts 122 and the static contacts 121 are prior art. The static contacts 121 are fixed, one row is kept vertical, and the other row is inclined. The bottom end of the moving contact 122 is hinged, and the static contact 121 is fixed. The hinged part of the moving contact 122 is connected to the output shaft of the driving motor 11 through a starting plate. The output shaft of the driving motor 11 drives the moving contact 122 to quickly rotate and abut against the static contacts 121 on both sides when the rack slides to both ends. The moving contact 122, the static contact 121, and the starting plate are all prior art. The working principle of the moving contact 122 and the static contact 121 is similar to the opening and closing of a household switch. The moving contact 122 is combined with the static contacts 121 on both sides to indicate the connection direction of the point rail at the switch.

[0031] In some other embodiments, the static contact 121 is vertically arranged without being tilted, and the arrangement of the static contact 121 is not limited.

[0032] Reference Figure 1 and Figure 2In this embodiment, an auxiliary moving contact 124 and an auxiliary static contact 123 are arranged on one side of the traditional multi-row moving contacts 122 and static contacts 121. The basic structure of the auxiliary moving contact 124 is the same as that of the moving contact 122, and the basic structure of the auxiliary static contact 123 is the same as that of the static contact 121. The auxiliary moving contact 124 and the auxiliary static contact 123 can be regarded as extended structures of the moving contact 122 and the static contact 121, but the difference is that a megohm-class fixed resistor with a preset resistance is connected at both ends of the auxiliary moving contact 124 and the auxiliary static contact 123, so that the action current of the drive motor 11 can be ignored when the auxiliary moving contact 124 and the auxiliary static contact 123 are engaged, and the current value is regarded as 0.

[0033] In some other embodiments, the auxiliary static contact 123 and the auxiliary moving contact 124 may be made of insulating materials such as ceramics and resins.

[0034] Reference Figure 1 and Figure 2 , a shell 14 is arranged on the outside of the auxiliary moving contact 124 and the auxiliary static contact 123, and the shell 14 plays a protective role; an angle sensor 15 is arranged on the side wall of the shell 14 close to the auxiliary moving contact 124 and the auxiliary static contact 123, and the angle sensor 15 corresponds one-to-one to the auxiliary moving contacts 124 on both sides of the output shaft of the drive motor 11, and the detection end of the angle sensor 15 corresponds one-to-one to the hinge end of the auxiliary moving contact 124, and detects the rotation angle of the auxiliary moving contact 124; the inner bottom wall of the shell 14 is provided with vibration sensors corresponding to the auxiliary moving contact 124 and the auxiliary static contact 123, which are used to detect the mechanical amplitude when the auxiliary moving contact 124 and the auxiliary static contact 123 are engaged and during the engagement process; the inner bottom wall of the shell 14 is provided with a length sensor corresponding to the action rod 13, and the length sensor is used to detect the extension length of the action rod 13; since the length sensor and the vibration sensor are both existing technologies, the technicians can install them according to the existing technology, and this embodiment will not be repeated.

[0035] Reference Figure 3 A camera 16 is disposed on the top wall of the housing 14 of the contact device 12, and LED lights are disposed on both sides of the camera 16 for fill light when the housing 14 is closed, so that the camera 16 can capture a clearer picture of the contact device 12 inside the housing 14; in some other embodiments, a smart camera 16 with an LED fill light function can be directly selected.

[0036] The implementation principle of a switch machine contact device for real-time status detection in the second embodiment of the present application is as follows: first, in this embodiment, a row of auxiliary moving contacts 124 and auxiliary static contacts 123 are added on the basis of the traditional solution, and a large current is switched on and off through a large resistor. When the switch machine 1 is operating, its action circuit can be regarded as 0, and the angle sensor 15 is used to measure its angle with higher reliability.

[0037] Secondly, the angle sensor 15, length sensor and vibration sensor provided in the above scheme respectively measure the rotation angle of the auxiliary moving contact 124 inside the switch machine 1, the extension length of the action rod 13 which rotates synchronously with the auxiliary moving contact 124, and the mechanical amplitude of the coupling device when the coupling device is operating and when the train passes, so as to provide more analysis basis for the technical personnel in the technical analysis.

[0038] The camera 16 operates synchronously with the angle sensor 15 and the vibration sensor, and is used to capture images of the abnormal period when the bonding device is abnormal or fails, so that the technicians can determine the cause of the failure based on the real-time information of the bonding device.
