Abstract

The invention discloses a data synchronization method and device for an upper and lower computer. The method includes that the upper computer receives a data synchronization request for a placement machine triggered by an authorized person, and the data synchronization request includes target data for controlling the placement machine. ; The upper computer sends the target data to the lower computer through the pre-established application layer protocol according to the data synchronization request; the lower computer receives the target data and overwrites the current data of the lower computer based on the target data. It can be seen that the implementation of the present invention synchronizes the batch data used to control the work of the placement machine from the upper computer to the lower computer of the placement machine through the application layer protocol constructed, so that the synchronization of batch data of the placement machine can be realized, thereby improving communication accuracy , and then improve the control efficiency and accuracy of the placement machine; and by synchronizing the batch data to the lower computer, the network bandwidth can be fully utilized, thereby improving the communication efficiency of the data.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a data synchronization method and device for an upper and lower computer. Background technique [0002] In the production line, the placement machine (also known as "mounter" or "Surface Mount System") is configured after the dispenser or screen printing machine, and the placement machine moves the placement head to the surface A device that accurately places components on PCB pads and is the core equipment of Surface Mount Technology (SMT). [0003] In actual industrial control, placement machines often involve batch data synchronization between the upper and lower computers. In order to achieve batch data synchronization, the current method used: basically rely on targeted programming to realize the sending of data one by one, and in the The peer overwrites the original data value after receiving it. However, practice has found that the method of targeted pr...
