Obviously, the following drawings are only some embodiments of the present disclosure. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0033] To enable those skilled in the art to better understand this solution, the following will clearly describe the technical solution in the embodiments of this solution in conjunction with the accompanying drawings in the embodiments of this solution. Obviously, the described embodiments are part of the embodiments of this solution, rather than all of the embodiments. Based on the embodiments in this solution, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this solution.

[0034] The term "including" and any other variations in the specification, claims, and the above-mentioned accompanying drawings of this solution mean "including but not limited to", and are intended to cover non-exclusive inclusion, not limited to the examples listed in the text. In addition, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order.

[0035] The following will describe the implementation of the present disclosure in detail with reference to specific accompanying drawings:

[0036] Figure 1 It is a schematic structural diagram of a dock remote control system provided for an embodiment of the present disclosure. Refer to Figure 1 This dock remote control system includes: a power supply module, a remote control terminal, a data transmission module, a field execution module, a monitoring module, and a central control module; the field execution module is connected to the monitoring module and the central control module. The field execution module is used to control the gantry crane to perform corresponding operations, and the monitoring module is used to monitor the operation parameters and environmental parameters of the gantry crane; the central control module is communicatively connected to the remote control terminal through the data transmission module, and the remote control terminal is used to remotely control the gantry crane; the remote control terminal is connected to the power supply module; the power supply module includes a voltage regulation module, a backup power supply, a power detection module, and a power switching module; the first end of the voltage regulation module is used to connect to the power grid, the second end of the voltage regulation module is connected to the first end of the power switching module, the second end of the voltage regulation module is connected to the second end of the power detection module and the second end of the power switching module, the third end of the power switching module is connected to the backup power supply, and the fourth end of the power switching module is connected to the remote control terminal.

[0037] In this embodiment, the power supply module provides stable power support for the entire remote control system of the wharf. One end of the voltage regulation module is connected to the power grid, and it regulates the voltage input from the power grid to meet the working voltage requirements of each part of the system. The power supply module includes a voltage regulation module, a backup power supply, a power detection module, and a power switching module. The first end of the voltage regulation module is connected to the power grid and is responsible for regulating the electrical energy obtained from the power grid to ensure that the voltage supplied to the remote control system of the wharf is stable and meets the equipment requirements. The power detection module is used to monitor in real time parameters such as the voltage and current of the main power supply (power grid power supply). Once an abnormality is detected (such as too low voltage or too large current), it will trigger a power switching action. According to the signal of the power detection module, it automatically switches to the backup power supply or resumes the main power supply to ensure the continuity and stability of power supply. When the power grid power supply is interrupted or the voltage is unstable, the backup power supply (such as a super capacitor, a storage battery, etc.) will automatically start to ensure that the remote control system of the wharf can continue to operate and ensure that the control and monitoring of the portal crane are not affected.

[0038] The remote control terminal is the interface for users to interact with the remote control system of the wharf. Users can send control instructions to the portal crane through this terminal to achieve remote operation. At the same time, it can also receive the status feedback and alarm information from the portal crane. The data transmission module is responsible for transmitting data between the remote control terminal and the central control module to ensure the accurate and rapid transmission of control instructions and status information.

[0039] The central control module receives the control instructions from the remote control terminal and forwards them to the on-site execution module. At the same time, it receives the operation parameters and environmental parameters of the portal crane from the monitoring module. According to the control instructions of the central control module, it directly controls the portal crane to perform corresponding operations, such as lifting and rotating. It monitors in real time the operation parameters (such as speed, position, load, etc.) and environmental parameters (such as temperature, humidity, wind force, etc.) of the portal crane and feeds back these parameters to the central control module.

[0040] Exemplarily, assume that at a large port terminal, the power grid of the terminal is supplying power normally. The voltage regulation module stably regulates the input 220V voltage of the power grid to different voltages such as 12V and 5V to meet the working requirements of each module in the terminal remote control system. At this time, the power detection module continuously monitors that the voltage of the power grid supply is 220V and the current is 10A, and everything is normal. The operator at the port in the remote control room observes through the operation interface of the remote control terminal that a cargo ship is about to dock and a batch of goods needs to be lifted. The operator clicks the lift button on the operation interface to send a control instruction. The data transmission module quickly transmits this instruction to the central control module. After receiving the instruction, the central control module immediately forwards it to the on-site execution module. The on-site execution module receives the instruction and controls the portal crane to start the lifting action. At the same time, the monitoring module continuously monitors that the running speed of the portal crane is 2 meters per second, the load is 5 tons, the ambient temperature is 25°C, the humidity is 60%, and the wind force is level 3, and feeds back these parameters to the central control module. The central control module then transmits these parameters to the remote control terminal through the data transmission module. The operator can clearly see the working status of the portal crane and the environmental parameters on the screen of the remote control terminal. However, in the afternoon, suddenly there is a thunderstorm, and the power supply of the power grid is affected, and the voltage drops to 180V instantaneously. The power detection module detects this abnormality and immediately triggers the power switching module to act. The power switching module quickly switches the power supply to the backup power supply. The backup power supply starts and continues to provide stable power for the entire terminal remote control system to ensure that the lifting operation of the portal crane is not interrupted. Until the power supply of the power grid returns to normal and the power detection module detects that the power grid voltage is stable at 220V and the current is normal, the power switching module automatically switches the power supply back to the power grid.

[0041] From the above, it can be concluded that in this embodiment, by integrating the power supply module, the precise monitoring module, the real-time data transmission module, and the intelligent central control module, the comprehensive remote monitoring and precise control of the terminal portal crane are realized. This embodiment not only ensures the stability and continuity of the power supply, effectively resists the interference of power grid fluctuations on the system operation, but also improves the safety and efficiency of the portal crane operation through the real-time monitoring and feedback mechanism. At the same time, the introduction of the remote control terminal greatly enhances the convenience and flexibility of operation, enabling users to master the status of the portal crane at any time, quickly respond to various operation requirements, and improve the automation level and overall operation efficiency of the terminal operation.

[0042] Such as Figure 2As shown, in an embodiment of the present disclosure, the power supply module includes: a voltage stabilizing diode U1, a resistor R3, a triode Q1, a triode Q2, a diode D2, a switching tube Q3, and a storage battery B1; the cathode of the voltage stabilizing diode U1 is connected to the second end of the voltage regulation module, the anode of the voltage stabilizing diode U1 is grounded through the resistor R3, the anode of the voltage stabilizing diode U1 is connected to the base of the triode Q1, the collector of the triode Q1 is connected to the base of the triode Q2, and the emitter of the triode Q1 is grounded; the emitter of the triode Q2 is connected to the cathode of the voltage stabilizing diode U1, the emitter of the triode Q2 is connected to the positive electrode of the storage battery B1, the negative electrode of the storage battery B1 is grounded, and the collector of the triode Q2 is connected to the remote control terminal; the control end of the switching tube Q3 is connected to the emitter of the triode Q2, the first end of the switching tube Q3 is connected to the anode of the diode D2, the cathode of the diode D2 is connected to the collector of the triode Q2, and the second end of the switching tube Q3 is connected to the positive electrode of the storage battery B1.

[0043] In this embodiment, the voltage stabilizing diode U1 and the resistor R3 constitute a power supply detection module, the triode Q1, the triode Q2, the diode D2, and the switching tube Q3 constitute a power supply switching module, and the storage battery B1 constitutes a backup power supply.

[0044] In this embodiment, an NPN type triode can be used as the triode Q1, a PNP type triode can be used as the triode Q2, and a P-channel field effect transistor can be used as the switching tube Q3.

[0045] During normal operation, the voltage regulation module is used to convert the grid voltage into a voltage suitable for the operation of the dock remote control system and output it. The power supply detection module is used to detect the magnitude of the voltage output by the voltage regulation module. When the voltage output by the voltage regulation module is normal, the voltage stabilizing diode U1 is broken down and conducts, a voltage signal is generated on the resistor R3, and this voltage signal is greater than the conduction voltage of the triode Q1. The triode Q1 conducts, the base of the triode Q2 is at a low level, and the triode Q2 also conducts. The switching tube Q2 is cut off. Therefore, the DC voltage output by the voltage regulation module is supplied to the remote control terminal after passing through the triode Q2. At the same time, the DC voltage output by the voltage regulation module can also charge the storage battery B1. Since the switching tube Q3 is cut off, the storage battery B1 does not discharge. When the power grid is powered off, the voltage output by the voltage regulation module is less than the voltage stabilizing value of the voltage stabilizing diode U1. The voltage stabilizing diode U1 is cut off, the base voltage of the triode Q1 is 0, the triode Q1 is cut off, the base of the triode Q2 is at a high level, the triode Q2 is cut off, and the switching tube Q2 conducts. At this time, the power supply circuit of the voltage regulation module is disconnected, and the storage battery B1 supplies power to the remote control terminal.

[0046] In this embodiment, an intelligent management of the power supply for the remote control system of the dock is achieved through a power detection and switching mechanism composed of a voltage stabilizing diode, a triode, and a switching transistor. Under normal power supply conditions, this embodiment can ensure a stable voltage output to the remote control terminal and simultaneously charge the battery for emergencies. Once the power grid is powered off, the module can respond quickly and automatically switch to the battery power supply mode to ensure the continuous operation of the remote control terminal, effectively avoiding system paralysis caused by power interruption, greatly improving the reliability and stability of the remote control system of the dock, and ensuring the safety and efficiency of dock operations.

[0047] As Figure 2 shown, in an embodiment of the present disclosure, the power supply module further includes: a resistor R4 and a diode D1; the first end of the resistor R4 is connected to the cathode of the voltage stabilizing diode U1, the second end of the resistor R4 is connected to the anode of the diode D1, and the cathode of the diode D1 is connected to the positive electrode of the battery B1.

[0048] In this embodiment, the resistor R4 and the diode D1 form a charging circuit, and the voltage output by the voltage regulation module can charge the battery B1 through the resistor R4 and the diode D1. Among them, the diode D1 can prevent the voltage in the battery B1 from flowing back, effectively avoiding circuit damage and equipment failures that may be caused by voltage backflow.

[0049] As Figure 2 shown, in an embodiment of the present disclosure, the power supply module further includes: a light-emitting diode LED2; the anode of the light-emitting diode LED2 is connected to the first end of the switching transistor Q3, and the cathode of the light-emitting diode LED2 is grounded.

[0050] In this embodiment, the function of the LED2 is to serve as an indicator light, and its on / off state intuitively shows the current power supply state of the remote control terminal to the staff.

[0051] When the power supply from the power grid is normal, the switching transistor Q3 is in the cut-off state, and the LED2 is not lit, indicating that the remote control terminal is using the power supply from the power grid. However, once the power grid is powered off or the power supply is abnormal, resulting in the need to switch the power supply from the power grid to the backup power supply (i.e., the battery B1), the switching transistor Q3 will quickly turn on, causing the battery B1 to start discharging to maintain the operation of the remote control terminal. At the same time, since the anode of the LED2 is connected to the first end of the switching transistor Q3 and the cathode is grounded, the LED2 will be lit.

[0052] In this embodiment, this not only facilitates the staff to quickly identify the power supply status of the system, but also improves the maintainability and fault diagnosis efficiency of the terminal remote control system for the dock. When LED2 lights up, the staff can immediately realize that the system is powered by the battery, and thus take corresponding measures, such as checking the grid power supply situation, evaluating the remaining battery power, etc., to ensure the continuous and stable operation of the remote control terminal.

[0053] As Figure 2 shown, in an embodiment of the present disclosure, the power supply module further includes: an operational amplifier U3 and a light-emitting diode LED1; the inverting input terminal of the operational amplifier U3 is connected to the first terminal of the switching transistor Q3, the non-inverting input terminal of the operational amplifier U3 is connected to the Vref reference voltage, the output terminal of the operational amplifier U3 is connected to the anode of the light-emitting diode LED1, and the cathode of the light-emitting diode LED1 is grounded.

[0054] In this embodiment, the operational amplifier U3 and the light-emitting diode LED1 constitute a battery voltage detection circuit, and during the discharge process of the battery B1, the battery voltage detection circuit starts to work.

[0055] The operational amplifier U3 is configured as a comparator. Its inverting input terminal is connected to the first terminal of the switching transistor Q3, and the non-inverting input terminal is connected to the Vref reference voltage. Vref is a preset reference voltage used to compare with the actual voltage of the battery. When the voltage of the battery B1 is greater than Vref, it indicates that the power in the battery is greater than the set value (that is, the system considers the power to be sufficient), and at this time, the operational amplifier U3 outputs a low level. Since the anode of the light-emitting diode LED1 is connected to the output terminal of the operational amplifier U3 and the cathode is grounded, LED1 does not light up at a low level. When the voltage of the battery B1 drops below Vref, it indicates that the power in the battery has dropped below the set value (that is, the system considers the power to be insufficient), and at this time, the operational amplifier U3 outputs a high level, causing LED1 to be lit. This visual signal reminds the staff that the battery power is low.

[0056] In this embodiment, by monitoring the battery voltage in real time, this embodiment can timely detect the situation of insufficient power and avoid the remote control terminal from interrupting services due to sudden power failure. Through the on-off state of LED1, the staff can intuitively understand the battery power situation without using professional test equipment.

[0057] As Figure 1 shown, in an embodiment of the present disclosure, the monitoring module includes a camera and a sensor assembly; the camera is used to collect on-site images, and the sensor assembly is used to collect the operation parameters and environmental parameters of the portal crane; the camera and the sensor assembly are connected to the central control module.

[0058] In this embodiment, the camera in the monitoring module is responsible for collecting real-time image information of the dock site, including the appearance status of the gantry crane, the loading and unloading conditions of the goods, etc. The sensor component focuses on collecting the operating parameters of the gantry crane, such as speed, position, load, etc., as well as environmental parameters, such as temperature, humidity, wind force, etc.

[0059] The camera and the sensor component transmit the collected information to the central control module respectively. After receiving these data, the central control module processes and analyzes them, and transmits the on-site image and parameter information to the remote control terminal for the operator to view and make decisions.

[0060] Exemplarily, assume that in a port dock, the high-definition camera in the monitoring module is installed at key positions of the gantry crane and important observation points of the dock. The camera collects clear on-site images at a speed of 30 frames per second, including the moment when the gantry crane lifts the goods, the placement of the goods at the dock, etc. At the same time, the speed sensor in the sensor component is installed at the transmission part of the gantry crane to monitor the lifting and running speed of the gantry crane in real time; the position sensor accurately measures the horizontal and vertical positions of the gantry crane; the load sensor accurately senses the weight of the lifted goods. In addition, temperature sensors, humidity sensors and wind speed sensors are respectively arranged around the dock to collect temperature, humidity and wind force data of the environment. During a goods loading and unloading operation, the camera clearly captures the process of the gantry crane lifting the goods. The speed sensor in the sensor component detects that the lifting speed of the gantry crane is slightly lower than the normal standard, and the position sensor shows that the position of the gantry crane is slightly deviated. These data are quickly transmitted to the central control module. After analyzing the data, the central control module sends the on-site image and abnormal operating parameters to the remote control terminal. After seeing this information on the remote control terminal, the operator immediately issues an adjustment instruction through the remote control terminal. The central control module conveys the instruction to the on-site execution module, timely correcting the running speed and position of the gantry crane, ensuring the safe and efficient progress of the goods loading and unloading.

[0061] In this embodiment, by integrating a high-definition camera and a comprehensive sensor component, real-time and accurate monitoring of the dock site and the operation of the gantry crane is achieved, improving the safety and efficiency of the goods loading and unloading operation. By instantly feeding back the on-site image and key operating parameters, the operator can quickly discover and correct abnormal situations, ensuring the smoothness and stability of the operation process.

[0062] As Figure 1 shown, in an embodiment of the present disclosure, the remote control terminal includes: a display unit, an input unit and a communication interface; the display unit is used to display the real-time status of the gantry crane and the operation interface; the input unit is used to receive operation instructions; the communication interface is connected to the data transmission module.

[0063] In this embodiment, the display unit is used to visually show the operator the real-time status of the gantry crane, such as the current operating speed, position, load condition, environmental parameters, etc. of the gantry crane, and at the same time present a clear operation interface to facilitate the operator to understand the various functions and operation options of the terminal remote control system.

[0064] The input unit is used to receive the operation instructions issued by the operator. The operator can issue various control instructions through input devices such as keyboards, mice, touch screens, etc., such as starting the gantry crane, stopping the gantry crane, adjusting the operating speed and direction of the gantry crane, etc.

[0065] The communication interface is responsible for establishing a connection with the data transmission module to ensure that the real-time status data shown by the display unit can be accurately transmitted from the central control module and the monitoring module, and at the same time ensure that the operation instructions issued by the operator through the input unit can be quickly and reliably transmitted to the central control module via the data transmission module to achieve precise remote control of the gantry crane.

[0066] Suppose that during the process of the gantry crane lifting goods, the load of the gantry crane shown on the display unit suddenly increases and exceeds the preset safety threshold. The operator immediately issues an instruction to pause the lifting through the input unit, and the communication interface quickly transmits the instruction to the data transmission module. After receiving it, the central control module controls the on-site execution module to pause the lifting action of the gantry crane, avoiding a possible safety accident.

[0067] In this embodiment, by integrating the display unit, the input unit and the communication interface, the visual display of the real-time status of the gantry crane, the convenient input of operation instructions and the efficient communication with the control system are realized, significantly improving the immediacy and safety of remote operation, effectively preventing potential safety risks, and ensuring the smooth progress of the cargo handling operation.

[0068] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
