Drawings
FIG. 1 is a flowchart illustrating steps of an AGV management control method according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
Referring to fig. 1, an AGV management control method according to the present invention specifically includes the following steps:
s1, the AGV is on-line to operate;
a plurality of landmark cards are distributed on the running route of the AGV, the landmark cards divide the AGV into a plurality of areas, the positions of the landmark cards are defined as stations, the lines among the landmark cards are defined as paths, and the stations and the paths correspond to stations in actual work.
S2, the AGV reads the landmark information;
the AGV running on the line reads the landmark card information.
S3, the AGV generates current position information;
and the AGV reads the landmark card information and then generates current position information by combining the state of the AGV.
It can be understood that, when the AGV is in a waiting state, the corresponding position information indicates that the AGV is at a certain station; when the AGV is in a running state, the corresponding position information indicates that the AGV runs on a certain path.
S4, the AGV management and control system periodically collects AGV information;
the AGV control system periodically collects all online AGV state information and position information through wireless communication, judges which station the AGV is at, and judges the AGV working state of each station.
It should be noted that, for the PLC-based management and control system, the period is a scanning period of the PLC program; for the PC-based management and control system, the period is a main program loop execution period.
S5, the AGV management and control system generates station and path information;
and the AGV management and control system generates station information and path information according to the collected detailed information.
Specifically, if the number of the material car and the number of the vehicle body bound with the AGVs are determined, the AGVs are associated with the information, and the management and control system processes the AGVs and generates AGVs and material information of each station and each path.
S6, the AGV control system effectively generates control information;
the management and control system combines the process requirements of all stations and the AGV working state, judges the AGV management and control state of the stations and generates management and control information.
And S7, the AGV executes actions according to the position information and the management and control information, when the AGB stops running or stops running, the running state of the AGV is updated, a new position value is generated, and the step S2 is repeatedly executed.
Specifically, for example, when the AGV runs in a certain section of pause-controlled path and receives pause information of the path, the AGV stops running, the waiting pause signal is cancelled, when the AGV runs to a certain station, it can be determined whether the station has a waiting signal, if the waiting signal exists, the AGV stops at the station and waits until the waiting signal is cancelled, if no waiting signal exists, the AGV enters the next section of path through the station, when the AGV pauses or stops running, the running state of the AGV can be updated, a new position value can be generated, and the new position value and the new state value can be collected by the control system in the next period.
The AGV receives path information broadcasted by the management and control system, and judges whether the AGV pauses, waits and selects which turnout at the turnout junction by combining the position and the state of the AGV.
It is understood that, for example: after the line edge ANDON pull switch triggers ANDON to stop, performing pause control on a corresponding station, and if an AGV exists in the station, pausing the AGV; when the downstream station is full, the waiting management and control are carried out on the station end, and when the AGV runs to the station, the waiting management and control are carried out until the downstream station is not full any more; when the material information needs to pop up the line body operation to the material, the turnout is selected to be popped up.
In this embodiment, the following three kinds of control instructions sent to the AGV by the control system are provided: (1) whether the path is paused; (2) whether the station waits; (3) where the selected switch number is allowed, these governing instructions are broadcast to all AGVs in the system.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
