Detailed Description
In order to make the technical means, the creation characteristics, the achievement of the purposes and the effects of the present invention easy to understand, the following embodiments specifically describe the technical scheme of the present invention with reference to the accompanying drawings.
< example >
The embodiment of the invention provides a method for replacing and processing abnormal material transportation in an internet of things factory, which comprises the following steps:
step one, a buff area outside a normal production working area is planned in the layout of an Internet of things factory.
And step two, presetting an alternative scheme for each carrying node which can generate abnormal conditions.
Alternatives include the following two: the first scheme is as follows: the new path is different from the original predetermined path, but the destination of the new path is still the original destination, i.e. the original destination is still reached according to the new path. The second scheme is as follows: the destination of the new path is the buff area, i.e. from the transfer node directly to the buff area. And when at least one new path reaching the original destination exists and all nodes in the new path are available, executing the conveying task reaching the original destination according to the first scheme. When all the existing new paths reaching the original destination are in an unavailable state, the conveying task of the changed destination is executed according to the second medium scheme.
And thirdly, when abnormal conditions of the conveying nodes occur in the conveying process, conveying is carried out according to the new path of the alternative scheme.
The embodiment of the invention also provides a path replacement processing system and a computer readable storage medium for the abnormal material transportation of the Internet of things factory, wherein the computer readable storage medium is stored with computer program instructions, and the computer program instructions realize the replacement processing method for the abnormal material transportation of the Internet of things factory when being executed by a processor.
The path replacement processing system for the abnormal material transportation of the factory of the Internet of things comprises a plurality of execution devices and an MCS control system.
The execution devices are classified into different grades according to the purposes, and the same grade of the execution devices are a plurality of. Referring to fig. 2, for example, in the embodiment, the system includes two floors of Floor1 and Floor2, the execution device includes a STK (stocker), an AGV (self-guiding mobile vehicle), and an LFT (lifting device), where STK1 is a stocker located on Floor1, the AGV is a vehicle (carrier robot) that performs self-guiding movement on Floor1, and LFT includes LFT1, LFT2, LFT3, and LFT4, where LFT1, LFT3 are materials entering from Floor1, and are transported to Floor2 for output; LFT2 and LFT4 are Floor2 entrance materials, and are transported to Floor1 for output. In this embodiment, the intelligent internet of things transport execution device adopted in the system is STK, AGV and LFT, but the implementation device is not limited thereto, and may be OHCV (overhead transport device) or the like according to the actual situation. The execution device is in communication connection with the MCS control system, and the execution device executes the conveying task according to the instruction of the MCS control system.
In contrast to the prior art MCS control system, the MCS control system according to the embodiment of the present invention specifically includes: the system comprises an alternative scheme storage module, a node state monitoring module, a path replacement judging module, a destination changing judging module and a new path executing instruction generating module.
The alternative storage module stores preset alternatives. Alternatives include the following two: the first scheme is as follows: the new path is different from the original predetermined path, but the destination of the new path is still the original destination, i.e. the original destination is still reached according to the new path. The second scheme is as follows: the destination of the new path is the buff area, i.e. from the transfer node directly to the buff area.
In the first scheme, when a plurality of new paths exist, the priorities of the paths are specified according to the customization of the manager. For example, a transfer node belonging to the same floor, class, and function as the current transfer node is defined as a priority node, and if there are a plurality of such priority nodes, the closest to the current transfer node may be defined as the most priority node, and the farther the distance is, the lower the priority is. In addition, the path without abnormal conveying nodes continues to convey along the original preset path.
In a second solution, the buff zone of the internet of things factory may be provided with a plurality of buff zones, e.g. one for each floor. When the transfer node is abnormal, the path from the transfer node to the same floor buff zone is taken as a new path. And when more than one floor buff area exists, more than one new path exists, and the priority of the paths is regulated according to the customization of management personnel. For example, a path from the current transport node to the nearest buff zone is defined as an optimal path, and the farther the distance is, the lower the priority is.
The node state monitoring module receives the signals uploaded by all the execution devices in real time, and monitors whether the corresponding execution devices are abnormal or not according to the signals uploaded by the devices. The abnormal condition of the conveying node comprises the condition that the conveying node is not available or is down. The analysis means for monitoring whether each type of execution device is normal is implemented in the prior art, and will not be described herein.
The path replacement judging module is used for judging based on the monitoring result of the node state monitoring module when the material reaches a preset conveying node in the process of executing a preset conveying task: if the preset conveying node is abnormal, judging that the path replacement is needed; if the preset conveying node is normal, judging that no path substitution is needed, and continuously executing the conveying task according to the preset path.
The change destination judging module is used for acquiring a first scheme from the alternative scheme storage module after the path replacement judging module judges that the path replacement is needed, and judging whether the first scheme can be executed based on the monitoring result of the node state monitoring module: if the method is executable, judging that the destination is not required to be changed; if the execution is not possible, it is determined that the destination needs to be changed, and the changed destination is the buff area.
The new path execution instruction generation module generates a corresponding new path execution instruction according to the judging result of the destination change judging module or not: when the destination is judged not to need to be changed, generating an execution instruction according to the first scheme; when it is determined that the destination needs to be changed, an execution instruction according to the second scheme is generated.
After the new path execution instruction is generated, the MCS control system automatically re-issues the new path execution instruction to the corresponding execution equipment, and the execution equipment executes the conveying task according to the new path.
Fig. 2 is a schematic diagram of a specific application scenario of a path-replacement processing system when the material transportation of an internet of things factory is abnormal in an embodiment of the present invention. With reference to figure 2 of the drawings,
primary transport tasks: STK1 of Floor 1- & gtSTK 2 of Floor2
Predetermined conveyance paths (as indicated by single solid arrows in fig. 2): STK1 → AGV1 → LFT1 of Floor1 → LFT1 of Floor2 → STK2.
When the AGV1 reaches the LFT1 of Floor1, an abnormal condition (such as equipment occupation or failure unavailability, equipment congestion, etc.) of the LFT1 occurs, at this time, the MCS control system automatically re-issues a new path execution instruction of the first scheme to the execution devices AGV1 and LFT3. The new path is shown by a dotted arrow in fig. 2, the LFT3 in the same direction on the same Floor replaces LFT1, after the material is conveyed to LFT3 of Floor2, the original conveying path is continued to continue conveying until the conveying task is completed.
If the LFT3 is not available, the MCS control system automatically re-issues a new path execution instruction of the second scheme to the execution device AGV1, and conveys the material to the BUFF area, and the task ends.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, but various modifications and variations of the present invention will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
