The data transmission module 120 is configured to receive and upload the operation state information according to a communication protocol corresponding to the logistics demand equipment. The instruction generating module 130 is configured to generate a carrying task instruction according to the operation state information. The scheduling module 140 is configured to send the transfer task instruction to the corresponding AGV, so that the AGV completes the transfer operation according to the transfer task instruction.
Particularly, in workshop production field, arranged many assembly lines respectively and carried out production operation, arranged different production facility (promptly commodity circulation demand equipment) on the assembly line of difference to carry the commodity circulation demand equipment to the assembly line through AGV dolly carrier that will be equipped with raw materials for production to guarantee that the assembly line is high-efficient going on. The carriers are usually plate frames, rubber frames, cartons and the like, and the carriers also have square, round and other shapes. With the application of the plant intelligent technology, devices in the whole plant are connected through an industrial Internet or an Internet of things, and each device is assigned with a corresponding IP (Internet Protocol) address. In order to improve the production efficiency, the AGV trolleys can be provided with a plurality of pieces, and are correspondingly configured according to different logistics demand equipment, for example, the working areas of the AGV trolleys are divided according to areas, and the configuration number of the AGV trolleys is determined according to different working areas. In order to facilitate management, the AGV trolleys can be numbered, the numbers of the AGV trolleys correspond to the IP addresses of the logistics demand equipment, and the carrying paths of the corresponding AGV trolleys are planned according to the areas where the logistics demand equipment are located. When the logistics demand equipment of a certain production line is in shortage of production raw materials, the number of the corresponding AGV can be inquired through the IP address of the logistics demand equipment, and the AGV is scheduled to convey the production raw materials for the logistics demand equipment.
Specifically, in the production process of the workshop, each logistics demand equipment conveys the production raw materials to the production line where the logistics demand equipment is located, and the data acquisition module 110 can acquire the demand condition of the production raw materials on each logistics demand equipment in real time. The data transmission module 120 establishes a communication connection with each logistics required device through a communication protocol corresponding to each logistics required device, receives the operating state information of each logistics required device, and uploads the received information to the instruction generation module 130. When the production material of a certain logistics demand equipment is about to be in short supply, the instruction generating module 130 can generate a corresponding carrying task instruction according to the operation state information of the logistics demand equipment. The carrying task instruction comprises a carrier type suitable for the assembly line, the IP address of the logistics demand equipment and the number of the AGV corresponding to the logistics demand equipment.

According to an embodiment of the present invention, as shown in fig. 2, the data transmission module 120 may include: the warehousing control system WCS121 is configured to determine a communication protocol with each logistics demand device according to a communication interface corresponding to each logistics demand device. Wherein the communication protocol comprises at least one of a Modbus communication protocol, a Siemens S7 communication protocol, and a TCP/IP communication protocol.
Specifically, devices on a workshop production line are usually controlled by using a PLC (Programmable Logic Controller), and when the workshop production line is constructed, the PLCs used by the devices on the same production line are different from each other due to cost optimization, and the different PLCs have different communication interfaces corresponding to different communication protocols. Generally, an interface corresponding to the Modbus communication protocol is an RJ11 interface, an interface corresponding to the siemens S7 communication protocol is an RJ45 interface, and an interface corresponding to the TCP/IP communication protocol is a network interface.
The warehousing control system WCS121 may determine a communication protocol with each logistics demand device according to a communication interface corresponding to each logistics demand device, for example, when the communication interface of the logistics demand device is an RJ11 interface, the warehousing control system WCS121 receives the running state information by using a Modbus communication protocol; when the communication interface of the logistics demand equipment is an RJ45 interface, the storage control system WCS121 receives the running state information by using a siemens S7 communication protocol; when the communication interface of the logistics demand equipment is a network interface, the warehousing control system WCS121 receives the running state information by using a TCP/IP communication protocol. After the WCS121 receives the operation state information of each logistics demand equipment, the operation state information of each logistics demand equipment may be uploaded to the instruction generating module 130.
According to an embodiment of the present invention, as shown in fig. 2, the instruction generating module 130 may include: and the manufacturing execution management system MES 131 is used for receiving the operation state information of each logistics demand equipment and generating a corresponding carrying task instruction according to the operation state information. The transport task instruction is generated by the manufacturing execution management system MES 131 according to the collected running state information of the logistics demand equipment, the state of the AGV and the task area.
Specifically, the manufacturing execution management system MES 131 mainly performs task-related configuration and fool-proof and error-proof check, where the task-related configuration mainly includes device IP address information, logistics route running point location configuration, whether to start an AGV, and product process attributes, and the fool-proof and error-proof check mainly includes logistics route work order check and whether the product process attributes match and link up. The manufacturing execution management system MES 131 generates corresponding transporting task instructions by integrating the above parameters and combining the received running state information of each logistics demand equipment, the state of the AGV and the task area. The transfer task instructions are communicated to the scheduling module 140 by way of an interface.
It should be noted that, when the transfer task instruction is generated, the code of the AGV to be transferred needs to be determined, and the AGV to be transferred can be determined according to the area where the logistics demand equipment needs to be transferred is located, the power state and the operating state of each AGV, and the priority of the transfer task.
According to an embodiment of the present invention, as shown in fig. 2, the instruction generating module 130 may further include: and the server module 132 is configured to receive and store the operation state information of each logistics demand equipment.
Specifically, for the diversity of interfaces of each logistics demand device in the production field, the server module 132 uses the WebService technology as a technical route of the data acquisition control system in the production process, each logistics demand device in the production field is used as a WebService component to provide a standard interface, and the server module 132 receives and stores the running state information of each logistics demand device. Moreover, when new production lines, AGV carts and other devices are added in subsequent production workshops, each newly added device may be integrated with the server module 132 through the WebService technology. The server module 132 can reduce the security risk of data interaction between the modules of the production scheduling system, and can also enhance the data transparency of each module.
According to an embodiment of the invention, as shown in fig. 2, the scheduling module 140 may include: the AGV dispatching system 141 is configured to receive the transport task instruction and issue the transport task instruction to the corresponding AGV. The carrying task instruction comprises a task station required to be docked by the task, the number of docking layers required by equipment of each station, the type of a carrying carrier and a task area. For example, the automatic plate loading and unloading machine has two layers, and the number of layers to be butted refers to the upper layer or the lower layer of the automatic plate loading and unloading machine, or both the upper layer and the lower layer, which need to be butted and conveyed, and of course, multiple layers are possible.
Specifically, the AGV trolley comprises the following main structural components: the device comprises a controller, a motion chassis, a lifting device, a butt joint carrying device, sensors corresponding to the parts and a photoelectric communication module. The controller is used as a center of the AGV, and after receiving the transfer task instruction sent by the AGV dispatching system 141, the controller of the AGV controls each component of the AGV according to the transfer task instruction to complete corresponding actions, so as to supplement materials for the logistics demand equipment. For example, the moving chassis of the AGV trolley can be controlled to move to the logistics demand equipment according to a certain path according to the IP address of the logistics demand equipment; for another example, the lifting device of the AGV trolley is controlled according to the number of the butt-joint layers of the logistics demand equipment, and the lifting device of the AGV trolley is controlled according to different equipment corresponding to the logistics demand equipment and the number of the butt-joint layers to complete ascending, descending and butt-joint actions with the equipment; for another example, the control of the butt-joint conveying device of the AGV trolley can be realized according to the type of the carrier, and the size adjustment of the butt-joint conveying device of the AGV trolley can be realized according to the type of the carrier, so that the device is suitable for being compatible in conveying different logistics carriers.
In an embodiment of the present invention, when the controller of the AGV receives the task transporting instruction, a control signal is generated according to the type of the carrier, and the control signal is sent to the docking transporting device, so that the docking transporting device completes the size adjustment according to the control signal, and determines the transporting path of the AGV according to the IP address of the logistics demand equipment and the serial number of the AGV.
Specifically, after the AGV receives the transporting task instruction, the controller of the AGV generates a corresponding control signal according to the type of the carrier, i.e. the size, shape and other information of the carrier, to which the logistics demand equipment is applicable, and sends the control signal to the docking transporting device of the AGV. After the butt joint conveying device of the AGV trolley receives the control signal, the size of a carrier bearing the carrier in the butt joint conveying device is adjusted according to the control signal, so that the carrier of the butt joint conveying device can be matched with the carrier to be conveyed, the butt joint conveying device of the AGV trolley can stably bear the carrier, and the situations that the carrier is unstable and production raw materials drop in the conveying process are prevented.
After the size adjustment of the butt joint carrying device of the AGV trolley is completed, the controller of the AGV trolley controls the butt joint carrying device to carry the carrier. The controller of the AGV dolly can confirm its transport route according to commodity circulation demand equipment IP address and the serial number of self to control the AGV dolly and carry according to the transport route, will be equipped with the carrier of raw materials for production and transport commodity circulation demand equipment, go on smoothly with the guarantee production.
According to one embodiment of the invention, generating a control signal according to a vehicle type comprises: acquiring initial sizes of a plurality of carriers; determining the initial size of a corresponding carrier according to the type of the carrier; and determining a control signal according to the initial size of the carrier and the AGV trolley number.
According to one embodiment of the present invention, determining control signals based on an initial size of a vehicle and an AGV cart number includes: determining the size of a carrier on the butt joint carrying device according to the serial number of the AGV trolley; when the initial size of the carrier is larger than the size of the carrier on the butt joint carrying device, generating a size increase signal; a size reduction signal is generated when the initial size of the carrier is less than the size of the carrier on the docking conveyance device.
Further, a size invariant signal is generated when the initial size of the carrier is the same as the size of the carrier on the docking conveyance device.
Specifically, in the actual production process, each AGV cart can complete the transportation of carriers of multiple sizes, and therefore, the initial sizes of all the carriers used by the corresponding logistics demand equipment are correspondingly stored in the controller of each AGV cart. After the controller of the AGV acquires the carrier type from the received carrying task instruction, the controller can query the initial size of the carrier corresponding to the carrier type according to the carrier type.
In the process of carrying, the butt joint carrying device of the AGV trolley continuously carries the carriers with different sizes, so that the sizes of the carriers on the butt joint carrying device are adjusted according to the carriers. After the initial size of the corresponding carrier is determined, the size of the carrier on the docking and conveying device can be determined according to the serial number of the current AGV trolley, namely the size of the carrier on the docking and conveying device after the AGV trolley finishes the last conveying. When the initial size of the carrier is larger than the size of the carrier on the docking and carrying device, the size of the carrier to be carried at this time is larger than the size of the carrier carried at the last time, and the controller needs to generate a size increasing signal to increase the size of the carrier on the docking and carrying device so as to be suitable for carrying the carrier to be carried at this time; when the initial size of the carrier is smaller than the size of the carrier on the docking and carrying device, the size of the carrier to be carried at this time is smaller than the size of the carrier carried at the last time, and the controller needs to generate a size reduction signal to reduce the size of the carrier on the docking and carrying device; when the initial size of the carrier is the same as the size of the carrier on the docking and carrying device, it is described that the size of the carrier to be carried at this time is the same as the size of the carrier carried at the previous time, the size of the carrier on the docking and carrying device is not changed, and the controller needs to generate a size-unchanged signal.
According to one embodiment of the invention, a docking conveyance device comprises: the device comprises a PLC control module, a width adjusting screw rod, a conveying device and a supporting platform, wherein the PLC control module is used for receiving a control signal and controlling the width adjusting screw rod to move according to the control signal so as to adjust the size of the supporting platform; the conveying device is used for moving the position of the carrier on the butt joint conveying device. The supporting platform is a carrier of the docking and transporting device in the above embodiment.
That is to say, after the controller of the AGV trolley generates a control signal according to the type of the carrier, the control signal is sent to the PLC module in the butt joint conveying device, and the PLC module controls the width adjusting screw rod to move according to the received control signal so as to adjust the size of the supporting platform, so that the size of the supporting platform is suitable for bearing the carrier. After the size of the supporting platform is adjusted, the AGV trolley moves to a carrier position needing to be carried, the carrier is carried, and the carrier is moved to the supporting platform position of the butt joint carrying device through the conveying device.
According to an embodiment of the invention, the docking and carrying device performs size adjustment according to the control signal, and the docking and carrying device comprises: when the PLC module receives a size increase signal, the width adjusting screw rod is controlled to move outside to increase the size of the supporting platform; when the PLC module receives the size reduction signal, the inner side of the width adjusting screw rod is controlled to move, so that the size of the supporting platform is reduced.
That is to say, through the removal of control width accommodate the lead screw, can realize the regulation to the supporting platform size, make the size of supporting platform be suitable for the size that bears the carrier that needs the transport to make butt joint handling device can accomplish the transport work steadily.
