Description

Technical Field

[0001] The present invention relates to a transportation lane-changing technology, and more specifically, it relates to a transportation lane-changing control method. Background Art

[0002] Transportation carriers are tools often used when transporting goods.

[0003] How to improve transportation efficiency and reduce transportation costs has become an important issue in promoting modern development. At present, most goods transportation is carried out manually, which causes no problems when transporting light goods. However, when the goods are heavy, it requires too much manpower and is quite laborious. Therefore, to solve the transportation problem, the prior art has manufactured transportation carriers, and the lane-changing control problem is inevitably involved in transportation carriers. This application aims to solve the lane-changing control method of transportation carriers. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a transportation lane-changing control method.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A transportation lane-changing control method includes the following two major steps:

[0006] The first step: In-station method:

[0007] S1. Start;

[0008] S2. Trigger the main track pair-shooting signal;

[0009] S3. Calculate the pusher corresponding to the current inlet;

[0010] S4. Determine whether there is a vehicle on the corresponding pusher. If not, go to S2;

[0011] S5. Whether the in-station reader reads the hanger within N milliseconds. If not, go to S13;

[0012] S6. Compare whether the hanger on the current pusher is the same as the hanger read by the reader;

[0013] S7. If not, update the pusher to the hanger read by the current reader;

[0014] S8. Whether to enter this station. If not, go to S11;

[0015] S9. Whether it is physically full / logically full of the station. If so, go to S11;

[0016] S10. Open the inlet cylinder;

[0017] S11. Correct the vehicle information in the pusher corresponding to the current inlet;

[0018] S12. End;

[0019] S13. It is interpreted that the hanger is empty, and transfer to S8;

[0020] There are the following situations for the inbound method:

[0021] 1. At the beginning of inbound, the controller controls the main track. When the main track pair - shooting signal is triggered, calculate the pusher corresponding to the current inlet after triggering. Then judge whether there is a vehicle on the corresponding pusher. If there is no vehicle, return to the place where the main track pair - shooting signal is triggered. If there is a vehicle, judge whether the inbound reader reads a hanger within N milliseconds. If a hanger is read, compare whether the hanger on the current pusher is the same as the hanger read by the reader. When they are inconsistent, update the pusher with the hanger read by the current reader. Then judge whether to enter this station. When it is not possible to enter this station, correct the vehicle information in the pusher corresponding to the current inlet and then end. When it is necessary to enter this station, then judge whether it is physically full / logically full. When the result is positive, correct the vehicle information in the pusher corresponding to the current inlet and then end. When the result is negative, open the inlet cylinder, and then correct the vehicle information in the pusher corresponding to the current inlet and then end;

[0022] 2. At the beginning of inbound, the controller controls the main track. When the main track pair - shooting signal is triggered, calculate the pusher corresponding to the current inlet after triggering. Then judge whether there is a vehicle on the corresponding pusher. If there is no vehicle, return to the place where the main track pair - shooting signal is triggered. If there is a vehicle, judge whether the inbound reader reads a hanger within N milliseconds. When the hanger read is empty, judge whether to enter this station. When it is not possible to enter this station, correct the vehicle information in the pusher corresponding to the current inlet and then end. When it is necessary to enter this station, then judge whether it is physically full / logically full. When the result is positive, correct the vehicle information in the pusher corresponding to the current inlet and then end. When the result is negative, open the inlet cylinder, and then correct the vehicle information in the pusher corresponding to the current inlet and then end.

[0023] Step 2: Outbound method:

[0024] The outbound method includes the out method and the out queue method;

[0025] Out method:

[0026] S1. Start of out;

[0027] S2. The outbound reader reads the vehicle;

[0028] S3. Judge whether there is a repeated hanger and the previous release time is less than 500. If so, transfer to S6;

[0029] S4. Judge whether it can go out. If not, transfer to S6;

[0030] S5. Add it to the outbound queue;

[0031] S6. End;

[0032] In the outbound method, the outbound process has the following situations:

[0033] The outbound process starts. The outbound reader starts to interpret the vehicle, and then it determines whether to repeat the hanger and whether the previous release time is less than 500. If so, it directly ends. If not, it determines whether the vehicle can go out. If it cannot go out, it directly ends. If it can go out, it joins the outbound queue and then ends.

[0034] Outbound queue method:

[0035] S1. The outbound queue process starts;

[0036] S2. The main track opposed signal is triggered;

[0037] S3. Calculate the pusher corresponding to the current exit;

[0038] S4. Determine whether there is a vehicle on the corresponding pusher. If so, go to S8;

[0039] S5. Open the release cylinder and record the release time;

[0040] S6. Correct the vehicle information in the pusher corresponding to the current exit;

[0041] S7. End;

[0042] S8. Wait for the next main track opposed signal and go to S2;

[0043] In the outbound method, the outbound queue method has the following:

[0044] The outbound queue process starts. The controller controls the main track, and the main track opposed signal is triggered. Then it calculates the pusher corresponding to the current exit, and then determines whether there is a vehicle on the corresponding pusher. When there is a vehicle, it waits for the next main track opposed signal and then returns to the main track opposed signal trigger point. When there is no vehicle, it opens the release cylinder and records the release time. After recording, it corrects the vehicle information in the pusher corresponding to the current exit and then ends.

[0045] The present invention is further configured that: in the first step, when S13 interprets that the hanger is empty, it means that the inbound reader is not installed or the inbound reader is damaged.

[0046] The beneficial effects of the present invention are:

[0047] Compared with the prior art, the transportation lane-changing control method of the present invention can accept the control of the controller. The user can directly control the transportation carrier tool through the controller to change lanes, realize the inbound and outbound of the loading mechanism on the transportation carrier tool, thereby realizing automatic control, with convenient operation, high transportation efficiency, and also saving transportation costs. Brief Description of the Drawings

[0049] Figure 2 This is a flowchart of the departure method in the transportation lane-changing control method of the present invention. Detailed Description of the Invention

[0050] Refer to Figure 1-2 for further description of the embodiments of the transportation lane-changing control method of the present invention.

[0051] For ease of explanation, relative spatial terms such as "upper", "lower", "left", and "right" are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientations shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "lower" than another element or feature will be positioned "above" the other element or feature. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the relative spatial descriptions used herein can be interpreted accordingly.

[0052] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0054] First step: Approach method:

[0055] S1. Start approaching;

[0056] S2. Trigger the main track pair signal;

[0057] S3. Calculate the pusher corresponding to the current entrance;

[0058] S4. Determine whether there is a vehicle on the corresponding pusher. If not, go to S2;

[0059] S5. Whether the entrance reader reads the hanger within N milliseconds. If not, go to S13;

[0060] S6. Compare whether the hanger on the current pusher is the same as the hanger read by the reader;

[0061] S7. If not, update the pusher to the hanger read by the current reader;

[0062] S8. Whether to enter this station. If not, go to S11;

[0063] S9. Whether it is physically full / logically full station. If so, go to S11;

[0066] S12. End;

[0067] S13. It is interpreted that the hanger is empty, and go to S8;

[0068] There are the following situations for the entry method:

[0069] 1. At the beginning of entry, the controller controls the main rail. When the main rail opposed signal is triggered, calculate the push rod corresponding to the current inlet after the trigger, and then judge whether there is a vehicle on the corresponding push rod. If there is no vehicle, return to the place where the main rail opposed signal is triggered. If there is a vehicle, judge whether the entry reader reads the hanger within N milliseconds. After reading, compare whether the hanger on the current push rod is the same as the hanger read by the reader. When they are inconsistent, update the push rod to the hanger read by the current reader. Then judge whether to enter this station. If it is possible not to enter this station, correct the vehicle information in the push rod corresponding to the current inlet and then end. When it is necessary to enter this station, then judge whether it is physically full / logically full station. When the result is positive, correct the vehicle information in the push rod corresponding to the current inlet and then end. When the result is negative, open the inlet cylinder, and then correct the vehicle information in the push rod corresponding to the current inlet and then end;

[0070] 2. At the beginning of entry, the controller controls the main rail. When the main rail opposed signal is triggered, calculate the push rod corresponding to the current inlet after the trigger, and then judge whether there is a vehicle on the corresponding push rod. If there is no vehicle, return to the place where the main rail opposed signal is triggered. If there is a vehicle, judge whether the entry reader reads the hanger within N milliseconds. When it is interpreted that the hanger is empty, judge whether to enter this station. If it is possible not to enter this station, correct the vehicle information in the push rod corresponding to the current inlet and then end. When it is necessary to enter this station, then judge whether it is physically full / logically full station. When the result is positive, correct the vehicle information in the push rod corresponding to the current inlet and then end. When the result is negative, open the inlet cylinder, and then correct the vehicle information in the push rod corresponding to the current inlet and then end;

[0071] Among them, N milliseconds is a value preset by the operator on the controller according to the actual situation;

[0072] The second step: The exit method:

[0073] The exit method includes the exit method and the exit queue method;

[0074] Exit method:

[0075] S1. Start the exit;

[0076] S2. The exit reader interprets the vehicle;

[0077] S3. Determine whether the hanger is repeated and the previous release time is less than 500. If so, go to S6;

[0078] S4. Determine whether it can exit the station. If not, go to S6;

[0079] S5. Add it to the exit queue;

[0080] S6. End;

[0081] The exit method in the exit method has the following situations:

[0082] Start the exit, the exit reader starts to interpret the vehicle, then determine whether the hanger is repeated and the previous release time is less than 500. When it is, it directly ends. When it is not, it determines whether it can exit the station. When it cannot exit the station, it directly ends. When it can exit the station, it is added to the exit queue and then ends;

[0083] Exit queue method:

[0084] S1. Start the exit queue;

[0085] S2. The main track opposed signal is triggered;

[0086] S3. Calculate the pusher corresponding to the current exit;

[0087] S4. Determine whether there is a vehicle on the corresponding pusher. If so, go to S8;

[0088] S5. Open the release cylinder and record the release time;

[0089] S6. Correct the vehicle information in the pusher corresponding to the current exit;

[0090] S7. End;

[0091] S8. Wait for the next main track opposed signal and go to S2;

[0092] The exit queue method in the exit method has the following:

[0093] Start the exit queue, the controller controls the main track, the main track opposed signal is triggered, then calculate the pusher corresponding to the current exit, and then determine whether there is a vehicle on the corresponding pusher. When there is a vehicle, wait for the next main track opposed signal and then return to the main track opposed signal trigger point. When there is no vehicle, open the release cylinder and record the release time. After recording, correct the vehicle information in the pusher corresponding to the current exit and then end;

[0094] In the first step, when it is interpreted in S13 that the hanger is empty, it means that the in-station interpreter is not installed or the in-station interpreter is damaged.

[0095] Compared with the prior art, the transportation lane-changing control method of the present invention can accept the control of the controller. The user can directly control the operation of the transportation carrier tool through the controller to change lanes, so as to realize the in-station and out-station of the loading mechanism on the transportation carrier tool, thereby realizing automatic control, with convenient operation, high transportation efficiency, and also saving transportation costs.
