Description

Technical Field

[0001] The present invention relates to the technical field of door crane operation monitoring, and in particular to a door crane video automatic tracking monitoring system and an operation method thereof. Background Art

[0002] Gantry cranes are heavy machinery commonly used in ports, warehouses, and large-scale logistics settings. To meet the demands of modern industrial production, operational requirements for gantry cranes are increasing, requiring operators to make timely adjustments based on the crane's operating status. Currently, gantry cranes are typically equipped with multiple surveillance cameras to provide visuals from different angles, enabling operators to monitor the crane's operation in real time and promptly operate the crane's operating module (i.e., its PLC control system) to ensure safe operation. Due to the complex operation process and rapidly changing environment, operators must manually switch between monitoring screens to obtain useful information. In practice, this manual switching process is prone to omissions and untimely switching, making it difficult to meet monitoring requirements. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a door crane video automatic tracking monitoring system, which solves the problem in the prior art that manual switching of monitoring images is prone to omissions and the switching is not timely.

[0005] The video acquisition module includes multiple cameras to capture video streams from different angles;

[0006] The sensor module monitors the door machine's working status in real time and transmits the monitoring information to the control module;

[0007] The control module determines the video stream to be displayed according to the working status;

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] By monitoring the working status of the door crane through sensors, the control module determines the video stream that needs to be displayed and issues instructions to the video switching module to switch, which is then displayed on the display module. The operator can quickly and accurately obtain key information, thereby greatly reducing the possibility of misoperation and accidents. There is no need for the operator to perform manual switching, which solves the problem of manual switching of monitoring screens in the existing technology that is prone to omissions and untimely switching; at the same time, it also improves the safety and efficiency of door crane operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 FIG. 4 is a schematic diagram of a video switching circuit according to an embodiment of the present invention. DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0032] In an exemplary embodiment, this embodiment provides a door machine video automatic tracking and monitoring system, including a control module, and a video acquisition module and a sensor module respectively connected to the control module in communication, the control module is also connected to the video switching module in communication, and the video switching module is connected to the display module in communication, wherein the control module is also connected to the operation module of the door machine itself (that is, the PLC control system of the door machine itself); the video acquisition module includes multiple cameras for real-time acquisition of multiple perspective video streams under the working state of the door machine; the sensor module is used to monitor the various working states of the door machine in real time, such as the movement state of the door machine, the position of the door body, load information, door opening and closing actions, etc.; the control module is responsible for analyzing and processing the status information provided by the sensor module, and based on the current working state of the door machine, controlling the video switching module to select and output the corresponding video stream; the video switching module automatically switches and displays the video streams acquired by multiple cameras according to the instructions of the control module; the display module includes a monitoring screen, which is responsible for displaying the selected video screen on the monitoring screen.

[0033] In a further exemplary embodiment, the video capture module uses multiple cameras to capture footage from various angles, including the operator's perspective, the operator's operating status, and the surrounding environment. The cameras can be installed at various locations on the operator, with their locations planned in advance based on the operator's movements. The sensor module senses the operator's information, allowing the system to identify the operator's different operating stages and provide a basis for switching between them. The sensor module can also sense the operator's different operating states to determine the operator's current operating stage, providing a basis for determining video switching. For example, when the operator is in a hoisting state, the control module can automatically switch to the operator's perspective, while when the operator is unloaded or in standby mode, the control module switches to the operator's perspective.

[0034] like Figure 1 As shown, in a further exemplary embodiment, the video switching module includes a multiplexer and an operational amplifier, wherein:

[0042] More specifically, using eight cameras as an example, the MAX440, an 8-channel high-speed video multiplexing chip, and peripheral circuitry are used. Eight video signals are input via IN0 to IN7. When the chip select signal EN is high, a specific video input is selected based on the video selection status codes of A0, A1, and A2. If multiple video signals are being switched, multiple MAX440s can be combined, controlled by controlling the chip select signal and the video channel selection status bits. The circuit's function is to select one of the multiple video input signals through the multiplexer, process the signal through an operational amplifier, and output the signal.
