Technical Field

[0001] The utility model relates to the technical field of switch machines, in particular to a machine vision monitoring device for switch machines. Background Art

[0002] Switch machines are basic equipment in railway signal systems, used to control switch switching, locking and supervision, and change the vehicle's travel path in the main line direction or lateral direction. With the continuous expansion of urban rail transit construction, the speed and volume continue to increase, and the failure rate of switch machines is on the rise, which can easily lead to non-indication, non-action, or incomplete action of switches, seriously affecting the operational efficiency of rail transit.

[0003] Since the switch machine is installed beside the track and is in a sealed state when working, it is affected by the timeliness of traffic operation. When a switch machine fails, it is very important to understand the status and location information of the internal components of the switch machine as soon as possible to speed up the problem analysis and processing. At present, the switch machine is not equipped with a monitoring device, and cannot provide intuitive information when the equipment fails, which delays the time of fault processing and directly affects the operation efficiency of rail transit. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides a machine vision monitoring device for a switch machine, which is arranged on a chassis cover of the switch machine, and a plurality of observation holes are arranged on the chassis cover. The machine vision monitoring device for the switch machine includes a vision acquisition module and a shell, and the shell cover is arranged on the chassis cover of the switch machine. The vision acquisition module is located in the shell, and the vision acquisition module includes a plurality of vision sensors, and the vision sensors collect internal image information of the switch machine through the observation holes.

[0008] Optionally, the upper cover is threadedly connected to the chassis cover.

[0009] Optionally, the surrounding shell walls are welded and fixed to the chassis cover.

[0010] Optionally, the shell is provided with a through hole for the cables to pass through.

[0011] Optionally, a waterproof joint is provided at the through hole.

[0012] Optionally, a plurality of line clips for fixing the cables are further provided on the side walls of the chassis cover.

[0013] Optionally, the visual acquisition module further includes a main control board, and the main control board is electrically connected to the visual sensor to receive internal image information acquired by the visual sensor.

[0014] Optionally, a plurality of limiting pins are provided on the chassis cover, and a plurality of limiting holes are correspondingly provided on the visual acquisition module, and the limiting pins extend into the corresponding limiting holes and are locked by nuts.

[0015] The switch machine vision monitoring device provided by the utility model has at least one of the following beneficial effects:

[0016] 1) By arranging a visual acquisition module on the chassis cover of the switch machine to collect internal image information of the switch machine, the working condition of the switch machine can be monitored in real time. When the switch machine fails, it can be discovered and handled in time, thereby ensuring the normal use of the switch machine;

[0017] 2) By providing a sealing ring between the surrounding shell wall and the upper cover for sealing, moisture and dust can be effectively prevented from entering the interior of the visual monitoring device, protecting the internal visual acquisition module from damage. In addition, by providing a sealing ring, the risk of the upper cover loosening or falling off due to vibration or impact can be reduced, which helps the stability and reliability of the visual acquisition module during operation;

[0018] 3) By providing a waterproof joint at the through hole for the cable to pass through, on the one hand, it is used to fix the cable to prevent the cable from loosening during operation, and on the other hand, it plays a sealing role to prevent external moisture and dust from entering the interior of the visual monitoring device through the gap between the cable and the through hole;

[0019] 4) By adding a cable clip on the side wall of the chassis cover, the cables can be effectively kept neat and orderly, avoiding confusion and entanglement of the cables, and improving the overall aesthetics of the device. In addition, through the design of the cable clip, the cables can be effectively fixed and protected, reducing the risk of mechanical damage caused by high-frequency opening and closing of the chassis cover, and extending the service life of the cables;

[0020] 5) The nailing technology can effectively fix the entire visual acquisition module firmly on the chassis cover.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Please refer to Figure 1 and Figure 2The present embodiment provides a machine vision monitoring device for a switch machine, which is arranged on a chassis cover 100 of the switch machine. A plurality of observation holes 101 are arranged on the chassis cover 100. The machine vision monitoring device for the switch machine includes a vision acquisition module 200 and a shell 300. The shell 300 is covered on the chassis cover 100 of the switch machine. The vision acquisition module 200 is located in the shell 300. The vision acquisition module 200 includes a plurality of vision sensors 201. The vision sensors 201 acquire internal image information of the switch machine through the observation holes 101.

[0032] By setting a visual acquisition module 200 on the chassis cover 100 of the switch machine to collect internal image information of the switch machine, the working condition of the switch machine can be monitored in real time. When a fault occurs in the switch machine, it can be discovered and handled in time, thereby ensuring the normal use of the switch machine.

[0033] In this embodiment, the shell 300 includes surrounding shell walls 301 and an upper cover 302 . The bottom of the shell 300 is an open structure. The surrounding shell walls 301 are fixed on the chassis cover 100 , and the upper cover 302 is detachably covered on the surrounding shell walls 301 .

[0034] Optionally, the surrounding shell walls 301 are a square structure formed by four sheet metal parts. The surrounding shell walls 301 are directly welded and fixed on the chassis cover 100. The welding accuracy is high, so that the surrounding shell walls 301 can be more accurately installed on the chassis cover 100, and the appearance after welding is smooth and flat, and the appearance is highly aesthetic.

[0035] Preferably, please refer to Figure 3 A sealing groove is provided at the top of the surrounding shell wall 301, and a sealing ring 400 is arranged in the sealing groove, and the sealing ring is clamped between the upper cover 302 and the surrounding shell wall 301. In other words, the surrounding shell wall 301 and the upper cover 302 are sealed by the sealing ring 400, which can effectively prevent moisture and dust from entering the interior of the visual monitoring device and protect the electronic components and visual sensors 201 on the internal visual acquisition module 200 from damage. In addition, by providing the sealing ring 400, the risk of the upper cover 302 loosening or falling off due to vibration or impact can be reduced, which helps the stability and reliability of the visual acquisition module 200 during operation.

[0036] Optionally, the upper cover 302 is threadedly connected to the chassis cover 100. For example, studs are welded on the chassis cover 100, and connection holes are correspondingly arranged around the upper cover 302. After the studs pass through the corresponding connection holes and are locked by threads, the upper cover 302 can be detachably installed, which is convenient for maintenance or replacement of the visual acquisition module 200.

[0037] Preferably, the housing 300 is provided with a through hole for the cable 500 to pass through. Since the internal image information collected by the visual acquisition module 200 needs to be transmitted to the external host computer, the cable 500 needs to be provided for connection. Therefore, a through hole for the cable 500 to pass through needs to be reserved on the housing 300. In this embodiment, since the upper cover 302 needs to be opened frequently, the through hole can be designed on the surrounding shell wall 301.

[0038] Further preferably, a waterproof connector 600 is provided at the through hole. The waterproof connector 600 is used to fix the cable 500 on the one hand to prevent the cable 500 from loosening during operation, and on the other hand to seal to prevent external moisture and dust from entering the interior of the visual monitoring device through the gap between the cable 500 and the through hole, thereby protecting the electronic components of the internal visual acquisition module 200 and the visual sensor 201 from damage.

[0039] Further preferably, a plurality of line clips 700 for fixing the cables 500 are also provided on the side wall of the chassis cover 100. Since the chassis cover 100 of the switch machine needs to be opened frequently, the signal cables 500 of the visual acquisition module 200 cannot be affected, so the line clips 700 can be added to the side wall of the chassis cover 100, which can effectively keep the cables 500 neat and orderly, avoid confusion and entanglement of the cables 500, and improve the overall aesthetics of the equipment. In addition, through the design of the routing card 700, the cables 500 can be effectively fixed and protected, reducing the risk of mechanical damage caused by high-frequency opening and closing of the chassis cover 100, and extending the service life of the cables 500.

[0040] In this embodiment, there are multiple visual sensors 201, which can be used to monitor the internal blocking switch, turning shaft, automatic switch and other closing components of the switch machine in real time to ensure the normal operation of these components and the stability of the railway signal system. Figure 4 As shown, for the isolating switch 800, the visual sensor 201 can monitor whether it is in the correct position, whether it is in an abnormal state or damaged; for the crank shaft 801, the visual sensor 201 can monitor the movement parameters of the crank shaft 801, so as to determine whether it has faults such as jamming, wear or breakage; for the automatic opener and closer 802, the visual sensor 201 can monitor the contact depth of the moving and static contacts of the upper bolt of the automatic opener and closer 802, and determine whether the fixing screws are loose or the static contact piece is broken.

[0041] In this embodiment, the lens of the visual sensor 201 can be set in the observation hole 101 at the corresponding position to facilitate image collection.

[0042] The visual acquisition module 200 also includes a main control board 202, which is electrically connected to the visual sensor 201 to receive the internal image information collected by the visual sensor 201. In this embodiment, the visual sensor 201 can be a high-definition camera with high resolution and wide-angle field of view, which can capture every detail inside the switch machine. The main control board 202 has a certain analytical ability and can accurately identify and locate various components and abnormal conditions inside the switch machine. Such a design is convenient for subsequent maintenance. When encountering equipment failure, only the faulty component needs to be replaced, and the entire device does not need to be replaced. It should be understood that the main control board 202 and the visual sensor 201 are both well-known devices in the art, and the utility model does not make any improvements to this. Those skilled in the art should know how to specifically implement the communication between the main control board 202 and the visual sensor 201. In addition, a communication module can also be integrated on the main control board 202 to facilitate the transmission of data to the host computer, and the utility model does not limit this.

[0043] In this embodiment, the model of the main control board 202 is, for example, DSP TMS320C6678+FPGAXC3S50.

[0044] In this embodiment, a plurality of limit pins 900 are provided on the chassis cover 100, and a plurality of limit holes are correspondingly provided on the visual acquisition module 200. The limit pins 900 extend into the corresponding limit holes and are locked by nuts. In this embodiment, the main control board 202 and the visual sensor 201 can be designed in an integrated manner, and then fixed on the chassis cover 100 as a whole. The limit pins 900 can be fixed on the chassis cover 100 by nailing technology. After tightening the nuts, spot welding is performed around the limit pins 900, thereby effectively fixing the entire visual acquisition module 200 firmly on the chassis cover 100. This nailing connection method can withstand greater tension and pressure, so that the visual acquisition module 200 remains stable and safe when subjected to vibration loads. Since the nailing connection has high strength and stability, the thickness of the sheet metal can also be reduced to a certain extent, further reducing the material cost.

[0045] In summary, the embodiment of the utility model provides a machine vision monitoring device for a switch machine, which collects internal image information of the switch machine by setting a visual acquisition module 200 on the chassis cover 100 of the switch machine. It can monitor the working condition of the switch machine in real time. When a fault occurs in the switch machine, it can be discovered and handled in time, thereby ensuring the normal use of the switch machine.

[0046] In addition, it should be recognized that although the present invention has been disclosed as a preferred embodiment, the above embodiment is not intended to limit the present invention. For any technician familiar with the art, without departing from the scope of the technical solution of the present invention, the above disclosed technical content can be used to make many possible changes and modifications to the technical solution of the present invention, or modified into equivalent embodiments of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
