[0072] The invention will now be further described with reference to the accompanying drawings.

[0073] With the acceleration of railway speeds and the improvement of transportation technology and carrying capacity in my country, higher requirements have been placed on safety assurance in railway freight transportation. Under normal circumstances, railway rolling stock departments currently use ground monitoring systems installed beside the tracks and manual inspections to dynamically monitor the operating status of vehicles passing through the lines.

[0074] However, it has been found that the existing technology has at least the following problems: the terrain of railway lines is becoming increasingly complex, manual inspection is labor-intensive and inefficient, and the number of monitoring points is increasing, which increases the maintenance and repair costs of monitoring equipment. Therefore, the method of manually operating and installing monitoring equipment on the ground to inspect freight cars can no longer meet the needs of field applications.

[0075] To solve the above-mentioned technical problems, at least one embodiment of the present invention provides a monitoring device, including a traveling unit 2, a power supply unit 4, a sensing unit, and a control unit 211; the traveling unit 2 is movably disposed on the side wall of the train; the sensing unit is disposed on the traveling unit 2, and the sensing unit is used to sense the working state of the train and generate corresponding sensing electrical signals; the control unit 211 is electrically connected to the sensing unit, and the control unit 211 is capable of receiving the sensing electrical signals; the power supply unit 4 is capable of converting the mechanical energy of the train's wheelset axle 5 into electrical energy and supplying power to the traveling unit 2, the sensing unit, and the control unit 211.

[0076] As can be seen from the above, by setting up a sensing unit to monitor the train's operating status, compared to manual operation and ground-mounted monitoring equipment for freight train inspection, the frequency and safety risks of personnel using handheld devices for monitoring are reduced. It also reduces the difficulty of installing and maintaining multiple ground-based monitoring devices, significantly lowering the equipment and personnel costs for collecting information data during railway freight train operation, and ensuring the safety of operating personnel. By placing the sensing unit on the movable traveling section 2, the monitoring range of the sensing unit is expanded, ensuring the accuracy and reliability of the collected information data and improving the detection accuracy rate. The inclusion of a power supply unit 4 ensures full utilization of energy, solving the problem of the lack of power supply equipment on freight trains and guaranteeing the normal operation of the traveling section 2, the sensing unit, and the control unit 211.

[0077] like Figure 1 , Figure 2As shown, a monitoring device includes a traveling unit 2, a power supply unit 4, a sensing unit, and a control unit 211. The traveling unit is movably mounted on the side wall of the train. The sensing unit is mounted on the traveling unit 2 and is used to sense the working state of the train and generate corresponding sensing electrical signals. The control unit 211 is electrically connected to the sensing unit and is able to receive the sensing electrical signals. The power supply unit 4 is able to convert the mechanical energy of the train's wheelset axle 5 into electrical energy and supply power to the traveling unit 2, the sensing unit, and the control unit 211.

[0078] It should be noted that the control unit 211 includes a host computer and a controller installed on the sensing unit. The controller is equipped with a signal processing circuit. The controller can receive sensing electrical signals and transmit them to the host computer. The controller can transmit the signals to the host computer in real time and quickly via long-range radio, GPS, Beidou, or 4G communication.

[0079] It should also be noted that the wheelset is the part of the train vehicle that comes into contact with the rail. It consists of two wheels, left and right, firmly pressed onto the same axle. The function of the wheelset is to ensure the operation and steering of the locomotive and rolling stock on the rail, bear all the static and dynamic loads from the locomotive and rolling stock, transfer them to the rail, and transfer the loads caused by uneven track to the various components of the locomotive and rolling stock.

[0080] It should also be noted that the number of monitoring devices on each carriage 1 is set according to needs, such as... Figure 2 As shown, a monitoring device can be installed on each side wall parallel to the length direction of the train.

[0081] By setting up sensors to monitor the train's operating status, compared to manual operations and ground-mounted monitoring equipment for freight train inspection, the frequency and safety risks of personnel using handheld devices for monitoring are reduced. The difficulty of installing and maintaining multiple ground-based monitoring devices is also reduced, significantly lowering the equipment and personnel costs for collecting information data during railway freight train operation and ensuring the safety of operating personnel. By mounting the sensors on the movable traveling section 2, the monitoring range of the sensors is expanded, ensuring the accuracy and reliability of the collected information data and improving the detection accuracy rate. The inclusion of a power supply section 4 ensures full utilization of energy, solving the problem of the lack of power supply equipment on freight trains and guaranteeing the normal operation of the traveling section 2, the sensors, and the control section 211.

[0082] like Figure 3 , Figure 4 , Figure 8As shown, in some embodiments, the traveling part 2 includes a traveling track 3, a traveling module 207, and a clamping module 209; the traveling track 3 is disposed on the side wall of the train and extends along the length direction of the train; the traveling module 207 is in contact with the traveling track 3 and can move along the traveling track 3; the clamping module 209 can cooperate with the traveling module to clamp the traveling track 3.

[0083] The walking track 3, the walking module 207, and the clamping module 209 provide the structural foundation for the installation and sensing of the sensing unit. The walking module 207 and the clamping module 209 cooperate to install the walking module 207 and the clamping module 209 on the walking track 3. At the same time, the clamping module 209 clamps and releases, which facilitates the assembly and disassembly of the walking module 207 and the clamping module 209, making it simple and convenient.

[0084] It should be noted that, as Figure 1 As shown, the length of the train is parallel to the X direction, the width of the train is parallel to the Y direction, the height of the train is parallel to the Z direction, and the X and Y directions are perpendicular to the Z direction.

[0085] It should also be noted that the train includes multiple carriages 1, which are used to place goods. Each carriage 1 has four side walls connected end to end, two of which are parallel to the length direction of the train and the other two are perpendicular to the length direction of the train. The running track 3 is set on the side walls that are parallel to the length direction of the train.

[0086] It should also be noted that, such as Figure 9 As shown, the travel track 3 is installed on the carriage 1 via the support block 302.

[0087] like Figure 4 , Figure 6 , Figure 7 As shown, in some embodiments, the walking module 207 includes a housing, a plurality of rotating shafts 20707, a plurality of walking wheels, a drive assembly, and a transmission assembly. The plurality of rotating shafts 20707 are rotatably mounted on the housing, and are spaced apart along the length of the train, with portions of the rotating shafts 20707 located outside the housing. The plurality of walking wheels correspond one-to-one with the plurality of rotating shafts 20707, and are mounted on the corresponding rotating shafts 20707. The walking wheels are located above and in contact with the walking track 3. The drive assembly is disposed within the housing and can drive one of the rotating shafts 20707 to rotate. The transmission assembly is disposed within the housing and can transmit the motion of one of the rotating shafts 20707 to the plurality of rotating shafts 20707.

[0088] By setting up a drive component to provide power, the power of the drive component is transmitted to multiple rotating shafts 20707 through a transmission component, so that the multiple rotating shafts 20707 rotate synchronously, thereby causing multiple walking wheels to rotate synchronously, and the walking module 207 moves along the walking track 3.

[0089] It should be noted that, as Figure 3 , Figure 4 As shown, the housing includes an outer shell 202 and a cover 201 connected to the outer shell 202. The outer shell 202 is provided with a through hole for the rotating shaft 20707 to pass through, and the rolling bearing is rotatably installed in the through hole. The outer shell 202 is provided with a cavity, and the drive assembly and transmission assembly are located in the cavity.

[0090] It should also be noted that, such as Figure 6 As shown, the walking module 207 also includes a dust cover 20706 disposed on the housing and a sealing ring 20708 disposed in the through hole. The dust cover 20706 is connected to the housing by means of integral molding, and the walking wheel is located inside the dust cover 20706 to prevent dust and impurities from entering the walking wheel and the cavity. The sealing ring 20708 is located on the end of the through hole away from the housing cover 201 to prevent dust from entering the rolling bearing and the cavity.

[0091] It should also be noted that, such as Figure 6 As shown, a traveling annular groove is provided on the circumference of the traveling wheel, and the cross-section of the traveling annular groove is V-shaped; the traveling track 3 matches the cross-sectional shape of the traveling annular groove to restrict the degree of freedom of the traveling wheel in the width direction of the train, and ensure the reliability of the traveling module 207 and the clamping module 209 installed on the traveling track 3.

[0092] like Figure 6 , Figure 7 As shown, in some embodiments, the drive assembly includes a drive member 20701, a drive wheel 20702, a driven wheel 20704, and a drive timing belt 20703; the drive member 20701 is disposed within a housing; the drive wheel 20702 is disposed on the shaft 20707 of the drive member 20701, and the drive wheel 20702 can rotate under the drive of the drive member 20701; the driven wheel 20704 is disposed on one of the multiple shafts 20707; the drive timing belt 20703 is wound around the drive wheel 20702 and the driven wheel 20704.

[0093] The belt drive, consisting of the driving pulley 20702, the driven pulley 20704, and the driving synchronous belt 20703, not only provides power for the movement of the driving wheels, but also features low noise, low vibration, simple structure, and convenient maintenance.

[0094] It should be noted that the drive component 20701 includes, but is not limited to, a servo geared motor.

[0095] It should also be noted that both the driving pulley 20702 and the driven pulley 20704 are synchronous belt pulleys. The driving pulley 20702 and the driven pulley 20704 are arranged at intervals in the height direction of the train, and the driven pulley 20704 is located above the driving pulley 20702.

[0096] like Figure 6 , Figure 7 As shown, in some embodiments, the transmission assembly includes a plurality of transmission wheels 20705 and a transmission timing belt 20710; the plurality of transmission wheels 20705 correspond one-to-one with a plurality of rotating shafts 20707, the transmission wheels 20705 are disposed on the corresponding rotating shafts 20707, and the transmission wheels 20705 are located inside the housing; the transmission timing belt 20710 is wound around the plurality of transmission wheels 20705.

[0097] The transmission and the synchronous belt 20710 form a belt drive, which transmits the power provided by the drive component to each shaft 20707, causing each shaft 20707 to rotate. The traveling wheel rotates with the shaft 20707, thereby driving the sensing unit to move along the traveling track 3, providing a structural basis for the sensing unit to monitor the working status of the train.

[0098] It should be noted that the transmission assembly is located above the drive pulley 20702, and the transmission pulley 20705 is a synchronous belt pulley.

[0099] like Figure 5 As shown, in some embodiments, the clamping module 209 includes a clamping assembly and a clamping drive 2091; the clamping assembly is movably disposed on the housing and is located below the travel track 3; the clamping drive 2091 is disposed inside the housing and connected to the clamping assembly, and the clamping drive 2091 can drive the clamping assembly to move in the height direction of the train to clamp or release the travel track 3.

[0100] By setting the clamping drive component 2091 to drive the clamping assembly to move in the height direction of the train, the clamping assembly moves closer to or away from the travel track 3, so that the clamping assembly and the travel wheel cooperate in the vertical direction to clamp the travel track 3, thereby realizing the installation of the travel module 207.

[0101] It should be noted that, as Figure 1 As shown, the train's height direction is parallel to the Z direction.

[0102] It should also be noted that the clamping drive component 2091 includes, but is not limited to, a servo linear module. The servo linear module can be a lead screw linear module or a cylinder linear module; this application does not impose any restrictions. The structure of the servo linear module is prior art, and its specific structure will not be described in detail here. The servo linear module can realize the linear motion of the load, making the movement of the load more flexible.

[0103] like Figure 5 As shown, in some embodiments, the clamping assembly includes an adapter 2092, a support 2094, a wheel carrier 2093, a driven shaft 2097, a clamping wheel 2099, a pressure sensor 2095, and an elastic element 2096; the adapter 2092 is movably mounted on the housing and is connected to the clamping drive 2091; the support 2094 is mounted on the adapter 2092; one end of the wheel carrier 2093 is movably mounted on the support 2094, and the wheel carrier 2093 is movable in the height direction of the train; from A driven shaft 2097 is disposed on the end of the wheel frame 2093 away from the support base 2094; a clamping wheel 2099 is disposed on the driven shaft 2097; a pressure sensor 2095 is disposed inside the support base 2094; an elastic element 2096 is sleeved on the wheel frame 2093, and the two ends of the elastic element 2096 abut against the wheel frame 2093 and the pressure sensor 2095 respectively; wherein, the two ends of the driven shaft 2097 pass through the support base 2094, and the support base 2094 is provided with a groove 2098 for the driven shaft 2097 to pass through.

[0104] The clamping drive 2091 drives the adapter 2092 to move in the height direction of the train. The support 2094, wheel frame 2093, driven shaft 2097, and clamping wheel 2099 move with the adapter 2092. The driven shaft 2097 is restricted to moving only in the height direction of the train by the groove 2098, thereby allowing the clamping wheel 2099 to move closer to or away from the travel rail 3, achieving clamping or releasing. The elastic element 2096 provides a buffer when the clamping wheel 2099 contacts the travel rail 3, preventing collisions between the clamping wheel 2099 and the travel rail 3 and causing damage to the clamping wheel 2099 and the travel rail 3. The pressure sensor 2095 detects the clamping force during the clamping process, thereby ensuring the normal clamping state of the clamping wheel 2099.

[0105] It should be noted that the outer shell 202 is provided with multiple through slots arranged at intervals along the length of the train, and the through slots extend along the height of the train; the adapter 2092 is provided with multiple guide blocks, and the multiple guide blocks correspond one-to-one with the multiple through slots. The guide blocks pass through the corresponding through slots and are connected to the clamping drive 2091. The shape of the through slots is adapted to the shape of the guide blocks.

[0106] It should also be noted that the wheel frame 2093 includes a support column and a support frame mounted on the support column. The support base 2094 and the adapter 2092 are provided with support holes for the support column to be inserted. The shape of the support column is adapted to the shape of the support hole. The driven shaft 2097 is mounted on the support frame. The driven shaft 2097 has shoulders at both ends, and the two ends of the driven shaft 2097 pass through the groove 2098. The shoulders abut against the support base 2094.

[0107] It should also be noted that a clamping annular groove is provided on the circumferential surface of the clamping wheel 2099, and the cross-section of the clamping annular groove is V-shaped; the cross-sectional shape of the traveling track 3 matches the cross-sectional shape of the clamping annular groove to restrict the degree of freedom of the traveling wheel in the width direction of the train, and ensure the reliability of the traveling module 207 and the clamping module 209 installed on the traveling track 3.

[0108] It should also be noted that the channel extends along the height direction of the train.

[0109] It should also be noted that the elastic element 2096 includes, but is not limited to, springs.

[0110] It should also be noted that the pressure sensor 2095 is electrically connected to the controller.

[0111] like Figure 3 , Figure 4 , Figure 7 As shown, in some embodiments, the sensing unit includes an attitude sensor, a positioning sensor, a camera module, and an environmental monitor 206; the attitude sensor is disposed on the housing and is used to sense the three-dimensional attitude of the train carriage 1 and generate corresponding attitude sensing electrical signals; the positioning sensor is disposed on the housing and is used to acquire the position information of the train and generate corresponding positioning sensing electrical signals; the camera module includes a lifting drive component disposed on the housing and a camera disposed on the lifting drive component, the camera is used to acquire the temperature information and image information of the train and generate corresponding temperature sensing electrical signals and image sensing electrical signals; the environmental monitor 206 is disposed on the housing and is used to sense the external environment of the train and generate corresponding environmental sensing electrical signals; wherein, the attitude sensor, the positioning sensor, the camera, and the environmental monitor 206 are electrically connected to the control unit 211.

[0112] By setting up a lifting drive component to move the camera in the height direction of the train, combined with the movement of the sensing unit in the length direction of the train, the temperature of the wheelset axle 5, the interior of the carriage 1, both ends of the train, and the bottom of the carriage 1 and the track lights can be detected, thereby realizing the detection task of the entire carriage 1; by using attitude sensors, positioning sensors and environmental detectors, the attitude, position and environmental information of the carriage 1 can be monitored and acquired.

[0113] It should be noted that the attitude sensor, positioning sensor, simulation module, and environmental monitor 206 are electrically connected to the controller.

[0114] It should also be noted that the environmental monitoring instrument 206 is located on the top of the housing. The environmental monitoring instrument 206 includes, but is not limited to, an environmental six-element monitoring instrument. The structure of the environmental six-element monitoring instrument is existing technology and will not be described in detail in this application. The environmental six-element monitoring instrument includes, but is not limited to, monitoring air humidity, air temperature, and wind speed, and generating corresponding environmental sensing electrical signals, thereby realizing the monitoring of the external environment of the train.

[0115] It should also be noted that, such as Figure 3 , Figure 4 , Figure 7 As shown, the camera includes a first camera 203 and a second camera 205, which are located above and below the housing, respectively. The lifting drive includes a first lifting drive 2051 and a second lifting drive 2052. The first camera 203 is mounted on the first lifting drive 2051, which can drive the first camera 203 to move in the height direction of the train. The second camera 205 is mounted on the second lifting drive 2052, which can drive the second camera 205 to move in the height direction of the train.

[0116] The first camera 203 includes, but is not limited to, an infrared camera. The specific structure of the infrared camera is existing technology and will not be described in detail in this application. The infrared camera can monitor 24 hours a day. The working principle of the infrared camera is that the infrared light emits infrared rays to illuminate the object.
