The observation and interaction mechanism 100 includes a plurality of camera devices 110 and a plurality of voice devices 120, which are respectively arranged at corresponding points on the gantry crane 400; the electric control mechanism 200 is respectively connected to each camera device 110 and the plurality of voice devices 120, and is used to automatically control each camera device 110 to shoot; the operating console mechanism 300 is connected to the electric control mechanism 200, and is further used to send the images shot by the plurality of camera devices 110 to the operating console mechanism 300, so that the operating console mechanism 300 displays the images shot by the plurality of camera devices 110 to the remote control personnel. The operating console mechanism 300 is also used to enable the plurality of voice devices 120 to play voice through the electric control mechanism 200.

[0052] In this embodiment, the multiple camera devices 110 and the multiple audio devices 120 in the observation interaction mechanism 100 can be installed at corresponding locations on the door operator 400. For example, the multiple camera devices 110 can be installed on the arm 401 of the door operator 400, in the machine room 405, or in the electrical room 406, and the multiple audio devices 120 can be installed on both sides of the door legs of the door operator 400. By installing multiple cameras 110 and multiple voice devices 120 at various locations on the door operator 400, and connecting each camera 110 and multiple voice devices 120 using an electronic control mechanism 200, the multiple cameras 110 are automatically controlled. Furthermore, the electronic control mechanism 200 is connected to the console mechanism 300, allowing the console mechanism 300 in the remote control room 405 to display images captured by the multiple cameras 110 in real time to the remote operator. When on-site workers enter the door operator 400 to perform operations, the remote operator can communicate with the on-site workers at the door operator 400 via the voice device 120, assisting them in their work. This improves operational efficiency and reduces safety risks. Furthermore, since the remote operator can monitor multiple door operators 400 simultaneously, there is no need to deploy additional auxiliary workers at the work site, effectively reducing labor costs.

Figure 2 A schematic diagram showing the arrangement position structure of the camera equipment of the port gantry crane remote control vision system on the gantry crane in some embodiments of the present invention is shown; Figure 3 It shows a schematic diagram of the layout structure of the camera equipment of the port gantry crane remote control visual system in the engine room in some embodiments of the present invention; Figure 4 Shown Figure 2 Structural diagram of the middle A direction; Figure 5 The diagram shows the structural layout of the camera equipment of the remote control vision system of the port gantry crane in the lower electrical room and high-voltage room in some embodiments of the present invention.

[0055] like Figure 2-Figure 5As shown, the multiple camera devices 110 may include: multiple fixed digital zoom gun cameras 111, a first digital ball camera 112, a wide-angle camera 116, multiple second digital ball cameras 113, multiple first fixed hemispherical cameras 114 and multiple second fixed hemispherical cameras 115. Specifically, three fixed digital zoom gun cameras 111 are respectively arranged on the head of the boom 401 of the gantry crane 400, the upper side of the main hook 402 and the upper side of the auxiliary hook 403, and the three fixed digital zoom gun cameras 111 are used to respectively observe the operation of the hooks; a first digital ball camera 112 is arranged on the top of the herringbone 404 of the gantry crane 400, and the first digital ball camera 112 is used to observe the operation of the boom 401 of the gantry crane 400 when it is raised; a wide-angle camera 116 is arranged on the other side of the top of the herringbone 404 of the gantry crane 400 away from the first digital ball camera 112, and the wide-angle camera 116 is used to observe the operation of the boom 401 of the gantry crane 400 when it is raised; four second digital ball cameras 113 are respectively arranged in front of the turntable of the gantry crane 400 and in the machine room 405, and the four second digital ball cameras 113 are used The operation conditions in the front of the turntable of the gantry crane 400 and in the machine room 405 are observed respectively; the two first fixed hemispheric machines 114 are respectively arranged in the electrical room 406 and the driver's cab (not shown) of the gantry crane 400, and the two first fixed hemispheric machines 114 are used to respectively observe the operation conditions in the driver's cab and the electrical room 406 of the gantry crane 400; the eight second fixed hemispheric machines 115 are respectively arranged in the high-voltage room 407, the lower electrical room 408, the two sides of the gantry end beam, the two sides of the left large vehicle door leg, the two sides of the right large vehicle door leg and the boarding gate of the gantry crane 400. The eight second fixed hemispheric machines 115 are used to respectively observe the operation conditions in the high-voltage room 407, the lower electrical room 408, the two sides of the gantry end beam, the two sides of the left large vehicle door leg, the two sides of the right large vehicle door leg and the boarding gate of the gantry crane 400. Therefore, by setting up multiple camera devices 110 at various points of the door machine 400, the movement of the components of the door machine 400 and the operation of the door machine 400 can be comprehensively monitored, so that the remote control personnel can know the situation at the operation site in a timely and accurate manner.

[0056] In some other embodiments of the present invention, the voice device 120 may include a one-way intercom and a horn speaker. The one-way intercom is set on the large door leg of the door machine 400, and the operating console mechanism 300 can communicate with the on-site workers through the one-way intercom. The horn speakers are set on both sides of the large door leg of the door machine 400, and the operating console mechanism 300 can broadcast notifications to the on-site workers through the one-way intercom.

[0057] Figure 6 Another structural diagram of the port gantry crane remote control vision system in some embodiments of the present invention is shown. Figure 6 As shown, the electronic control mechanism 200 may include: multiple electronic controllers 210, multiple secondary switches 220, a main switch 230, and a main network video recorder 240. Each electronic controller 210 is connected to a corresponding camera device 110 and is configured to automatically control the corresponding camera device 110. Each secondary switch 220 is connected to a corresponding camera device 110 and is configured to receive images captured by the corresponding camera device 110. The main switch 230 is connected to multiple secondary switches 220, and each secondary switch 220 transmits its received images to the main switch 230. The main network video recorder 240 is connected to the main switch 230 at one end and to the console mechanism 300 at the other end. The main switch 230 transmits its received images to the main network video recorder 240 (NVR). The main network video recorder 240 stores the received images and transmits them to the console mechanism 300.

[0058] In this embodiment, the electronic controller 210 can automatically control the corresponding camera 110 to capture images. For example, it can control the camera 110 to rotate at a fixed time or to present different video layouts based on the operating mode of the door operator 400. Automatic control of the camera 110 by the electronic controller 210 is conventional technology and will not be further described here. The secondary switches 220 receive images captured by the corresponding camera 110, and the main switch 230 transmits the images received from each secondary switch 220 to the main network video recorder 240. This effectively expands the network of camera devices 110 while reducing the load on the main switch 230. Furthermore, the main network video recorder 240 supports multiple video encoding formats and can effectively compress video files, saving storage space. Using the main network video recorder 240 to store and transmit images to the console mechanism 300 can effectively reduce storage costs and bandwidth fees.

[0059] The following further describes the port gantry crane remote control visual system according to an embodiment of the present invention in conjunction with a specific embodiment of the placement of the camera device 110 and the voice device 120 on the gantry crane 400. Figure 7 The schematic diagram of the structure of the port gantry crane remote control vision system in some embodiments of the present invention is shown as follows: Figure 7As shown, in some other embodiments of the present invention, the electric controller 210 may include: an arm head electric controller 211, an A-shaped frame electric controller 212, a lower electrical room electric controller 213 and an upper electrical room electric controller 214. Among them, the arm head electric controller 211 is connected to multiple fixed digital zoom gun cameras 111, and the arm head electric controller 211 is used to automatically control the multiple fixed digital zoom gun cameras 111; the A-shaped frame electric controller 212 is connected to the first digital ball camera 112 and the wide-angle camera 116, and the A-shaped frame electric controller 212 is used to automatically control the first digital ball camera 112 and the wide-angle camera 116; the lower electrical room electric controller 213 is connected to multiple second fixed hemispherical cameras 115, and the lower electrical room electric controller 213 is used to automatically control multiple second fixed hemispherical cameras 115; the upper electrical room electric controller 214 is connected to multiple second digital ball cameras 113 and multiple first fixed hemispherical cameras 114, and the upper electrical room electric controller 214 is used to automatically control multiple second digital ball cameras 113 and multiple first fixed hemispherical cameras 114. By using a plurality of electronic controllers 210 to respectively control a plurality of corresponding imaging devices 110 , mutual interference of signals can be avoided, and the stability of the electronic controller 210 in controlling the imaging devices 110 can be improved.

[0060] like Figure 7 As shown, in some other embodiments of the present invention, the secondary switch 220 may include: a first switch 221, a second switch 222, a third switch 223, and a fourth switch 224. The first switch 221 is connected to multiple fixed digital zoom box cameras 111 and is configured to receive images captured by the multiple fixed digital zoom box cameras 111. The second switch 222 is connected to the first digital dome camera 112 and the wide-angle camera 116 and is configured to receive images captured by the first digital dome camera 112 and the wide-angle camera 116. The third switch 223 is connected to multiple second digital dome cameras 113 and multiple first fixed dome cameras 114 and is configured to receive images captured by the multiple second digital dome cameras 113 and the multiple first fixed dome cameras 114. The fourth switch 224 is connected to multiple second fixed dome cameras 115 and is configured to receive images captured by the multiple second fixed dome cameras 115. By setting up multiple secondary switches 220 to receive images captured by their respective corresponding cameras 110, and then having the main switch 230 send the images received from each secondary switch 220 to the main network video recorder 240, the network of the camera devices 110 can be effectively expanded while reducing the load on the main switch 230.

[0061] like Figure 6As shown, the console mechanism 300 includes a remote console 310 and a voice interface 320. The remote console 310 is provided with a display connected to the main network video recorder 240 and used to display images sent by the main network video recorder 240. The voice interface 320 is connected to the main switch 230, which is connected to each voice device 120. The voice interface 320 is used to transmit voice to each voice device 120 through the main switch 230, so that each voice device 120 can play the voice.

[0062] In this embodiment, the display can display images captured by each camera device 110 and received by the main network video recorder 240 in real time, allowing remote control personnel to monitor the operation of the door operator 400 in real time. Furthermore, when on-site operators enter the door operator 400 to perform operations, the remote control personnel can use the voice interface 320 to transmit voice messages to each voice device 120 via the main switch 230. The remote control personnel can then communicate with the on-site operators at the door operator 400 through the voice devices 120, assisting them in their work. This improves operational efficiency and reduces safety risks. Furthermore, since remote control personnel can monitor multiple door operators 400 simultaneously, there is no need to deploy additional auxiliary personnel at the work site, effectively reducing labor costs.

[0063] like Figure 7 As shown, the port gantry crane remote control visual system of the embodiment of the present invention may further include: an access control mechanism 500, which is arranged at the boarding gate of the gantry crane 400, and is used to control on-site workers to enter and exit the gantry crane 400. Figure 8 The schematic diagram of the structure of the access control mechanism in the remote control visual system of the port gantry crane in some embodiments of the present invention is shown. Figure 8 As shown, the access control mechanism 500 may include: an access control 510, a boarding indicator light 520, and an alarm 530. The access control 510 is provided at the boarding gate of the door machine 400 and is used to control on-site workers from entering and exiting the door machine 400. The boarding indicator light 520 is provided on the access control 510 and is used to display a first indication state when an on-site worker has not entered the door machine 400. The boarding indicator light 520 is also used to display a second indication state when an on-site worker requests to open the access control 510. The boarding indicator light 520 is also used to display a third indication state when the access control 510 is opened and a fourth indication state when an on-site worker enters the door machine 400. The alarm 530 is provided on the access control 510 and is used to sound an alarm when the access control 510 is opened.

[0064] In this embodiment, a card reader is installed on the access control system 510. The card reader is used to identify and record the entry and exit information of field workers. Field workers can enter and exit the door machine 400 by swiping their cards at the card reader. The card reader is connected to the control console mechanism 300 via one of the secondary switches 220. The control console mechanism 300 is also used to store the entry and exit information of field workers recorded by the card reader. This prevents unauthorized personnel from entering or exiting the door machine 400, thereby improving security. Furthermore, the boarding indicator 520 can be displayed as a solid green light when a field worker has not entered the door machine 400 and the door machine 400 is in remote operation mode; it can be displayed as a flashing green light when a field worker requests to open the access control system 510; it can be displayed as a flashing red light when the access control system 510 is open; and it can also be displayed as a solid red light when a field worker has entered the door machine 400 and the door machine 400 is in local operation or maintenance mode to alert the field worker. The alarm 530 may be a buzzer alarm that sounds when the door access 510 is opened and stops sounding after the door access 510 is closed to remind the on-site workers, thereby further improving the safety of on-site operations.

[0065] like Figure 6 As shown, the remote control vision system for the port portal crane 400 also includes a backup network video recorder 250, which is connected to the primary network video recorder 240 and is used to back up the images stored in the primary network video recorder 240. Therefore, if a storage device fails, data can be restored from the backup, reducing the risk of data loss.
