进一步地，所述步骤S22中，在设备信息存储于后台控制中心的数据库的过程中，以设备信息中的控制系统是否属于OPC UA服务器而进行分类存储，当控制系统不属于OPCUA服务器时，则需要对该设备进行预先定义，从而确保不同厂商设备的不同的控制系统均可与该后台数据中心建立互联互通。当设备的控制系统属于OPC UA服务器时，则利用OPCUA协议本身通用的特性，以及通信范围广和通信性能高的特点进行统一的数据传输，当控制系统的类型不属于OPC UA服务器时，则对控制系统进行预先定义，使其能够满足与后台控制中心的互联互通，该对设备信息进行预先定义的过程，满足了不同厂商设备中不同的控制系统均可实现与该后台控制中心进行互联互通的连接方式，解决了现有应用中因不同厂商的设备中携带的控制系统类型不同而不能进行统一协调调度的不便局面。Further, in the described step S22, in the process that the equipment information is stored in the database of the background control center, it is classified and stored according to whether the control system in the equipment information belongs to the OPC UA server, and when the control system does not belong to the OPC UA server, then The equipment needs to be pre-defined to ensure that different control systems of equipment from different manufacturers can establish interconnection with the back-end data center. When the control system of the device belongs to the OPC UA server, the general characteristics of the OPCUA protocol itself, as well as the characteristics of wide communication range and high communication performance, are used for unified data transmission. When the type of the control system does not belong to the OPC UA server, the The control system is pre-defined so that it can meet the interconnection and intercommunication with the background control center. The process of pre-defining the equipment information satisfies the requirement that different control systems in different manufacturers' equipment can realize the interconnection and intercommunication with the background control center. The connection mode solves the inconvenient situation that unified coordination and scheduling cannot be carried out in the existing application due to the different types of control systems carried in the equipment of different manufacturers.

When the type of the control system does not belong to the OPC UA server, the specific pre-defined method for the device is to record the IP address, TCP port, component URL and component type fully qualified name of the device. Data association with the background control center.
进一步地，所述控制程序均用于控制对应的设备执行相关的操作和对设备进行数据的采集；当控制程序的变量名称发生改变时，设备的执行动作发生变化，使生产流程实现的具体功能发生改变，当采集到所述的控制程序的变量名称时，可判断设备的某一执行动作结束。每台设备的控制程序用于控制该设备完成相应的操作任务，通过对控制程序中操作指令即变量名称的修改实现对设备控制程序的修改，进而实现对设备操作任务的调控。Further, the control programs are all used to control the corresponding equipment to perform related operations and to collect data on the equipment; when the variable name of the control program changes, the execution action of the equipment changes, so that the specific functions realized by the production process are changed. If there is a change, when the variable name of the control program is collected, it can be judged that a certain execution action of the device has ended. The control program of each device is used to control the device to complete the corresponding operation task. The modification of the device control program is realized by modifying the operation instruction in the control program, that is, the variable name, thereby realizing the regulation of the equipment operation task.
进一步地，所述变量名称还包括终止变量，终止变量用于控制生产工艺流程的终止，当变量名称满足终止变量的值时，即可实现生产工艺流程的终止。通过终止变量的设置，当达到终止变量的值时，即意味着本生产流程结束。Further, the variable name also includes a termination variable, and the termination variable is used to control the termination of the production process. When the variable name satisfies the value of the termination variable, the termination of the production process can be realized. Through the setting of the termination variable, when the value of the termination variable is reached, it means the end of the production process.
进一步地，所述变量名称还包括生产流程控制变量，用于控制生产流程执行的先后循序，当上一生产流程执行终止时，控制下一生产流程的开始。生产流程程控制变量用于控制生产流程的执行先后顺序，当一个生产流程满足终止变量的值时，即本流程结束时，由生产流程控制变量控制下一生产流程开始。Further, the variable name also includes a production process control variable, which is used to control the sequence of execution of the production process, and control the start of the next production process when the execution of the previous production process is terminated. The production process control variable is used to control the execution sequence of the production process. When a production process satisfies the value of the termination variable, that is, when the current process ends, the production process control variable controls the start of the next production process.
本发明通过建立设备信息与后台控制中心的数据映射，实现后台控制中心对设备信息的管控，即变更设备的控制程序的变量后，即可实现对设备的操作任务的把控，通过对产品的生产工艺流程的建档，并由后台控制中心调度后，后台控制中心即可按照建档文件对关联设备进行调度，实现产品的生产流程的执行，在产品的生产工艺流程的建档过程中，通过对工艺路径、控制程序、加工程序文件等的修改编辑，即可实现对不同产品的生产流程的建立，当后台控制中心对该建档文件获取和解析后，按照建档文件对不同产品进行加工，该过程满足了不同产品的生产和加工。The invention realizes the management and control of the equipment information by the background control center by establishing the data mapping between the equipment information and the background control center, that is, after changing the variables of the control program of the equipment, the control of the operation tasks of the equipment can be realized.
