In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise. All directional indicators in the embodiments of the present application (such as upper, lower, left, right, front, rear, top, bottom … …) are only used to explain the relative positional relationship between the components, the movement, etc. in a particular posture (as shown in the drawings), and if the particular posture is changed, the directional indicator is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Furthermore, reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic flow chart illustrating a control method for FTR padlock protection according to an embodiment of the present application. The control method for FTR lock padlock protection specifically comprises the following steps:

step 100: and acquiring an initial inching lifting signal.

The inching lifting signal is a signal generated after an operator inputs preset data through the operating device, and the signal is used for the operator to transmit information whether to operate the crane spreader to lift the container at the moment. It is easy to understand that the initial inching lifting signal is the inching lifting signal when the operator performs inching lifting operation on the container for the first time. The system can be operated to lift only after acquiring a first inching lifting signal transmitted by an operator, and when the system receives the signal, the container is in a landing state capable of being lifted, the lifting safety is highest, otherwise, potential safety hazards easily exist.

Step 200: and controlling the container to perform the initial inching lifting action according to the initial inching lifting signal.

The inching lifting action is the action of the container under the lifting of lifting devices such as a lifting appliance, and the initial inching lifting action is the first inching lifting action of the system after receiving the initial inching lifting signal. After the system receives the initial inching lifting signal, the lifting appliance is in a safe state capable of lifting, and the container is also in a safe landing state capable of being lifted, so that the risk of controlling the container to perform the first inching lifting action is low and the safety is high.

In addition, fig. 2 is a diagram illustrating a finish effect after a container is initially clicked in a control method for providing FTR lock protection according to another embodiment of the present application. As shown in fig. 2, after the container is initially lifted by the inching, the container is in contact with the flatbed or the container is initially separated from the flatbed, the flatbed does not generate an upward supporting force to the container, the container is only subjected to its own weight and an upward pulling force of the spreader, and the rope of the spreader is in a tight state. According to past experience, the distance l1 between the container and the flat car should be within 10mm due to inertia effect, etc., but the distance is not limited in the present application.

Step 300: and acquiring the current weight of the container in the process of initial inching lifting.

The current weight of the container is the instant weight of the container at a certain moment, and the current weight obtained in the step is the instant weight of the container in the process of carrying out initial inching lifting. It should be noted that the instant weight can be obtained through a weight detecting device in the system, and the weight detecting device can obtain the weight lifted by the lifting appliance, including the weight of a single lock head and the total weight of each lock head. Because the weight of the container is usually fixed in the hoisting process, when the FTR lock is padlock-mounted, the phenomenon that the weight of the lock head suddenly rises can occur. Therefore, the current weight of the container is acquired, so that whether the padlock phenomenon occurs in the lifting process or not can be judged, and the padlock phenomenon can be found in time and stopped in time when the system lifts the container, so that safety accidents are avoided.

Step 400: and generating a plurality of control information in stages according to the preset weight of the container, the current weight of the container and the preset lifting distance of the container.

The preset weight of the container is the weight of the container previously input by the operator in the system, and the preset weight is only related to the specification of the container. The preset lifting distance of the container is the inching lifting distance input by an operator in advance according to the container weight of the container, and the lifting appliance inching lifts the container according to the preset distance, so that the phenomenon of padlock of the FTR lock can be greatly avoided, and the lifting safety of the container is guaranteed. The control information is control instruction information generated by the system, and the control information is used for controlling the container to perform inching lifting action in stages until the container is completely unlocked.

The control method for FTR lock padlock protection comprises the steps of obtaining a primary inching lifting signal; controlling the container to perform primary inching lifting action according to the primary inching lifting signal; acquiring the current weight of the container in the process of initial inching lifting; and generating a plurality of control information in stages according to the preset weight of the container, the current weight of the container and the preset lifting distance of the container, wherein the control information is used for controlling the container to perform inching lifting actions in stages until the container is completely unlocked. According to the control method, whether inching is carried out or not is controlled by sending an inching lifting signal by an operator, and the container is controlled to lift in a preset distance by inching, so that step-by-step unlocking is realized, the safe operation of the container unlocking process is ensured, personnel for observing and commanding the lifting beside a flat car can be reduced, the labor cost is saved, and the operation efficiency is improved.

In a possible implementation manner, fig. 3 is a schematic flowchart illustrating a control method for providing FTR padlock protection according to another embodiment of the present application. As shown in fig. 3, the step 400 may further include the following steps:

step 410: and judging whether the current weight of the container is less than or equal to the preset weight of the container or not.

Whether the current weight of the container is smaller than or equal to the preset weight of the container is an important basis for judging whether the container is padlocked, and subsequent lifting action can be carried out only on the premise that no padlock risk exists in the container. Thus, the current weight of the container needs to be compared with the preset weight of the container before the risk of tripping the lifting process padlock can be further reduced.

Step 411: when the current weight of the container is smaller than or equal to the preset weight of the container, generating a plurality of control information in a staged manner according to the preset lifting distance, wherein the plurality of control information are used for controlling the container to perform inching lifting action in a staged manner.

Step 412: and when the current weight of the container is greater than the preset weight of the container, giving out an early warning and stopping lifting.

When the current weight of the container is greater than the preset weight of the container, the padlock is not always generated in the scene, but the padlock risk exists, so that the early warning is required to be sent to an operator, and the lifting is not continued, the purpose of avoiding the padlock to the greatest extent is achieved, and the operation safety is guaranteed.

Specifically, fig. 4 is a schematic flow chart illustrating a method for generating control information according to a lifting distance in a control method for protecting an FTR lock according to another embodiment of the present disclosure. As shown in fig. 4, step 411 may further include the following steps:

step 4111: and acquiring a first lifting duration and a first lifting speed according to the first preset lifting distance.

The preset lifting distance is a lifting distance input by an operator in advance, the first preset lifting distance is a lifting distance when the container is subjected to first inching lifting, the distance is a distance input into the system in advance according to the past lifting experience of the container, and the lifting distance is set on the premise of lowest padlock risk by combining factors such as specification and model of the container, weight and the like. The lifting duration and the lifting speed are both lifting parameters of the lifting appliance in the lifting process, and both the lifting duration and the lifting speed are calculated by the system according to the preset lifting distance, so that the first lifting duration and the first lifting speed are both lifting parameters of the lifting appliance in the first preset lifting distance range. Wherein, the lifting speed can be adjusted by controlling the acceleration of the engine accelerator.

Step 4112: and acquiring a second inching lifting signal.

The second inching lifting signal is the same as the first inching lifting signal and is a lifting signal sent by an operator through the operating device, and after the operator finishes the first inching lifting action of the container and determines that no padlock risk exists according to data such as the current weight of the container, the input of the execution signal of the second inching lifting can be carried out. The process is directly controlled by an operator, is more flexible, and can directly judge whether the padlock is used according to the display of the system on data such as weight and the like without the assistance of ground operators.

It should be noted that the receiving sequence of the first lifting duration, the first lifting speed and the second inching lifting signal is not sequential and is determined according to the specific data transmission condition, but only after the three types of data are completely received by the system, the subsequent steps can be executed to further reduce the risk of padlock.

Step 4113: and generating first control information according to the first lifting duration, the first lifting speed and the second inching lifting signal.

The system determines that no padlock risk exists at present according to the received first lifting duration, the first lifting speed and the second inching lifting signal, and then the lifting appliance and the container can be controlled to carry out second inching lifting action, so that the container is unlocked step by step. The first control information is used for controlling the container to perform the second inching lifting action, and when the second inching lifting action is completed, the container stops continuously lifting.

In a possible implementation scenario, fig. 5 is a diagram illustrating a second inching lift completion effect in a control method for providing FTR padlock protection according to another embodiment of the present application. As shown in fig. 5, the first preset lifting distance l2 may be 30-50 mm, such as 40mm, and the specific first preset lifting distance depends on the container weight of the container and the operation condition of the dock, and the specific value of the first preset lifting distance is not further limited in this application.

Step 4114: and acquiring a second lifting duration and a second lifting speed according to the second preset lifting distance to generate second control information.

And when the container finishes the second inching lifting, continuously executing the third inching lifting. The second preset lifting distance is the same as the first preset lifting distance and is a safe lifting height distance input by an operator in advance, and the distance is set on the premise of lowest padlock risk according to the specification, the model and the weight of the container, the position of the container after the second inching lifting and other factors. Correspondingly, the system can calculate appropriate second lifting time length and second lifting speed according to the second preset lifting distance, and then follow-up steps are carried out, so that the container is further safely unlocked.

Step 4115: and acquiring a third inching lifting signal.

The third inching lifting signal is a lifting signal which is generated after the second inching signal and is sent by an operator through the operation of the operation device, and the third inching lifting signal is used for controlling the container to carry out third inching lifting action. In addition, the system can control the container to carry out the third inching lifting action only after the three data of the third inching lifting signal, the second lifting duration and the second lifting speed are completely acquired. The process ensures that the third inching lifting action of the container is safer to execute, and further reduces the possibility of padlock in the lifting process.

It should also be noted that the receiving sequence of the second lifting duration, the second lifting speed, and the third inching lifting signal is not sequential, and is determined according to the specific data transmission condition, but the system can execute the subsequent steps only after receiving the three data completely, so as to further reduce the risk of padlock.

Step 4116: and generating second control information according to the second lifting duration, the second lifting speed and the third inching lifting signal.

And the system determines that no padlock risk exists at present according to the received second lifting duration, the second lifting speed and the third inching lifting signal, and can control the lifting appliance and the container to perform third inching lifting action so as to gradually unlock the container. Generally, when the container completes the third jog lift, the container may reach the top of the FTR lock, i.e., the container is in a fully unlocked state, at which time the jog lift is complete. The second control information is used for controlling the container to perform the third inching lifting action, and when the third inching lifting action is completed, the container stops continuously lifting.

In a possible implementation scenario, fig. 6 is a diagram illustrating a third inching lift completion effect in a control method for providing FTR padlock protection according to another embodiment of the present application. As shown in fig. 6, the second preset lifting distance l3 may be 70-90 mm, and the specific second preset lifting distance depends on the container weight of the container and the operation condition of the dock, and the specific value of the second preset lifting distance is not further limited in this application.

It should be noted that the three times of inching to complete inching lifting unlocking of the container are only examples, the specific inching times can be determined according to specific implementation scenarios, the staged inching times can be greater than two times or less than two times, and the application does not further limit the specific inching times.

Optionally, as shown in fig. 4, after step 4113, the method may further include the following steps:

step 41130: and acquiring the rotation duration of the container according to the preset reverse rotation angle of the container.

The preset reverse rotation angle is an angle value input by an operator, and the angle value can be determined according to the specific shape of the FTR lock head. The rotation time of the container is calculated according to the preset reverse rotation angle and the rotation speed parameter of the related device. By acquiring the preset reverse rotation angle and the rotation time, the container can be controlled to rotate slightly after leaving the surface of the flat car, so that the container is more convenient to unlock. For example, the preset reverse rotation angle may be 0.34 degrees, which depends on the specific structure and application scenario of the FTR lock, and the application does not further limit the specific value of the preset reverse rotation angle.

Step 41131: and generating a rotation control instruction according to the rotation time length of the container and the preset rotation speed.

Fig. 7 is a schematic diagram illustrating the effect of reverse rotation of a container in a control method for FTR padlock protection according to another embodiment of the present application. As shown in fig. 7, the preset rotation speed is a rotation parameter of the spreader, and the rotation control command is used for controlling the container to rotate reversely. According to the rotation time and the preset rotation speed, the system generates a rotation control instruction, so that the container rotates moderately before the last inching lifting is carried out, the padlock risk is further reduced, the operation safety is guaranteed, and the operation efficiency is improved.

In a possible implementation manner, step 411 may further include step 4110:

step 4110: and acquiring the total weight of the container and the weight of the single lock head, and stopping lifting when the total weight of the container and the weight of the single lock head change suddenly.

The total weight of the container is the sum of downward forces generated by the container to the spreader, and comprises two conditions, wherein the first condition is that the container is normally unlocked, and then the total weight of the container is the container weight of the container; the second situation is when the container is padlocked, and the sum of the downward forces experienced by the spreader at this time will be greater than the container weight of the container. FTR locks are arranged at four corners of the container, the weight of a single lock refers to a downward force generated at each FTR lock, and the two conditions are also included, wherein the first condition is that the container is normally unlocked, and the weight of each lock is close to a preset value or less than the preset value; the second is that the container has a padlock, and at some point the force at the individual lock head increases beyond the preset value. The term "sudden change" means that the weight is greater than a preset weight value at a certain moment, such as the first second to the last second, and the weight is judged to have "sudden change". When the total weight of the container or the weight of a single lock head changes suddenly, the situation that one or more lock heads have padlocks can be judged, and operation risks exist, so that the lifting of the container needs to be stopped, and safety accidents are avoided. And the weight can be obtained in real time in the process of carrying out periodical inching lifting on the container so as to avoid padlocks to the maximum extent.

Specifically, fig. 8 is a schematic flow chart illustrating a control method for FTR padlock protection according to another embodiment of the present application. As shown in fig. 8, step 200 may further include the following steps:

step 210: and acquiring initial lifting duration and initial lifting speed according to the initial inching lifting signal and the preset container weight of the container.

The preset container weight of the container is container weight information which is input in advance according to the specification and signals of the container, and comprises the empty container weight of the container and the heavy container weight of the container when the container is filled with goods. Wherein, the empty case weight of container is usually at 3 ~ 8 tons, and the heavy case weight of container is usually at 25 ~ 45 tons, and specific numerical value is decided according to the different containers of different docks, and this application does not further limit to the predetermined case weight of container. The system generates initial lifting time and initial lifting speed according to a preset container weight input by an operator in advance, which is a precondition for carrying out initial inching lifting action on the container. And the preset container weight, the initial lifting time length, the initial lifting speed and other initial inching lifting parameters are not changed unless the container specification of the wharf changes.

Step 220: and generating initial inching lifting control information according to the initial lifting duration and the initial lifting speed.

After the system acquires initial inching lifting time length, initial lifting speed and other initial parameters according to the preset container weight of the container, initial inching lifting control information is generated and used for controlling the container to perform initial inching lifting action. Initial inching lifting parameters are reset according to the container of the container, so that the initial inching lifting action of the container is more reasonable, the situation that the container is overhigh or too fast in lifting for the first time and a padlock appears is avoided, and the operation safety is further guaranteed.

Next, a controller provided in another embodiment of the present application is described with reference to fig. 9.

Fig. 9 is a schematic structural diagram of an FTR latch protection control system according to another embodiment of the present application.
