Interface integration method of AGV job automatic scheduling system and MES system

An interface integration method of integrating automatic guided vehicle (AGV) job automatic scheduling system and manufacturing execution system (MES) system, comprising an AGV job automatic scheduling system unit, an MES system unit and a data transmission and processing unit;

• wherein the data transmission and processing unit comprises a first interface configured to communicate with the MES system unit, and a second interface configured to communicate with the AGV job automatic scheduling system unit;
• the data transmission and processing unit performs interface integration through a data dictionary;
• the data dictionary comprises a material information definition data set, a transportation job requirement data set, an external inventory information data set, an inventory information data set, a material status interaction data set and an AGV status data set;
• wherein the interface integration method comprises:
• the MES system unit changing the transportation job requirement data set and the external inventory information data set in the data transmission and processing unit through the first interface, to allow the AGV job automatic scheduling system unit in combination with the material information definition data set to generate a transportation job requirement;
• the MES system unit changing the material status interaction data set through the first interface, to allow the AGV job automatic scheduling system unit in combination with the material information definition data set to control inventory material check and overdue material processing;
• the MES system unit obtaining the inventory information data set through the first interface, to guide on-site production equipment to schedule production in combination with the material information definition data set;
• and the MES system unit obtaining the AGV status data set through the first interface, to display running status of the AGV job automatic scheduling system;
• and
• the AGV job automatic scheduling system unit changing the transportation job requirement data set in the data transmission and processing unit through the second interface to feedback job execution status;
• wherein the transportation job requirement generated by the AGV job automatic scheduling system unit comprises a warehousing job, and the warehousing job comprises returning surplus materials from a loading station of the on-site production equipment, returning an empty pallet from the loading station, and warehousing a finished product from an unloading station;
• wherein steps of performing the warehousing job comprise:
• step 1, storing the material information definition data set, the material status interaction data set, the transportation job requirement data set, the external inventory information data set, the inventory information data set and the AGV status data set in the data transmission and processing unit;
• step 2, the MES system unit distributing a job requirement by changing the transportation job requirement data set and the external inventory information data set;
• step 3, the AGV job automatic scheduling system unit accepting a job by receiving the transportation job requirement data set and the external inventory information data set, further generating the transportation job in combination with the inventory information data set, the external inventory information data set and the material information definition data set, and then feeding back a status of the job by updating data items in the transportation job requirement data set;
• step 4, the AGV job automatic scheduling system unit assigning a specific AGV to perform the transportation job, updating the transportation job requirement data set, and then feeding back a job progress in the transportation job requirement data set through an execution status of the AGV;
• step 5, the AGV job automatic scheduling system unit deleting information about pallets carried by the AGV from the external inventory information data set when loading is completed, adding the information about pallets carried by the AGV to the inventory information data set when unloading is completed, and updating a status of the data items in the transportation job requirement data set when the loading is completed or when the unloading is completed, to give feedback on the status of the job;
• and
• step 6, the MES system unit and the AGV job automatic scheduling system unit sending and receiving the transportation job requirement data set and the external inventory information data set regularly or in real time by means of timed polling in combination with data status triggering, the MES system unit regularly sending the material information definition data set to the AGV job automatic scheduling system unit through the data transmission and processing unit, and the AGV job automatic scheduling system unit sending in real time the inventory information data set to the MES system unit through the data transmission and processing unit.
