The core of the production flow chart comprises three parts of production start, procedure production and production end. Process production may be configured with multiple processes, each of which requires a separate process flow diagram, as shown in fig. five, with the core of the process flow diagram including four parts of a production inlet, a production start, a production step, and a production end. The production entry node needs to bind the RFID reader-writer, and the practical meaning is that when the RFID reader-writer bound by the procedure reads the RFID tag in the production process, the procedure starts to produce, and the product bound by the RFID tag can be produced based on the procedure flow chart of the procedure until the procedure is completed, and the procedure is finished, so that the product enters the next link.
The module is intended to realize production automation, but is also compatible with a semi-automatic mode, and the RFID read-write mode triggers the starting of the procedure, and can also be replaced by the manual selection of a terminal to start (pause and stop).
Each node of the production flow chart and the process flow chart can be configured with rules, and the rules consist of production conditions, production actions and production data.
The production rule is an abstract concept, and the practical significance lies in determining the sequence and relation among data to be collected, such as the rule of cooling the product when the temperature of the product reaches 25 ℃, the production condition when the temperature of the product reaches 25 ℃, the production action when the temperature of the product reaches 25 ℃, and the time and the times of cooling can be recorded by the background to form production data.
Each production step of the process can be bound to a data acquisition device, and data collection includes both automatic and manual collection. The realization of automatic collection needs to bind the acquisition equipment in the production step, and meanwhile, a module for operating the acquisition equipment is added in the software layer, for example, the production step needs to input the weight data of the electronic scale, the software layer needs to be added with an electronic scale control module, and the data of the electronic scale is automatically input into the system through a serial port, a network port and other forms. The manual collection is realized by a worker scanning the RFID tag through an RFID handheld reader-writer, identifying the product and manually inputting data into the system.

If the step 3 and the step 1 of the procedure are configured, the step 1 reads the tag through the RFID read-write module, the field is RFID=E123, the step 2 is entered, the step 2 waits and records through the weight read module, the weight field is weight=2, when the weight parameter is read, the weight write interface is triggered and invoked, the parameter weight=2 and the RFID=E123 are transmitted, and the procedure is completed. The process steps may also be configured as semi-automatic configuration processes, i.e., partially using an automated configuration process, while waiting for a manual operation completion signal after a certain step, and then performing other steps.
(2) Hardware end dynamic deployment module
The module mainly realizes the initialization of the process flow, loads the configured flow information, and needs to be carried out before actual production.
