Machine tool data acquisition apparatus and method thereof

Abstract

The invention discloses a machine tool data acquisition apparatus used for processing a plurality of far-end acquisition commands sent by a plurality of supervising devices. The machine tool data acquisition apparatus comprises that: a supervising device link module which receives the far-end acquisition commands sent by the supervising devices; a command making module which makes a plurality of near-end acquisition commands according to the far-end acquisition commands, wherein, the near-end acquisition commands have a sequence, and each near-end acquisition command is corresponding to a plurality of parameter acquisition requests in each parameter combination; a machine tool link module which sends a plurality of the parameter acquisition requests corresponding to each near-end acquisition command to a tool machine according to the sequence of the near-end acquisition commands and obtains a corresponding parameter value.

Description

technical field [0001] The present invention relates to the monitoring technology of a machine tool / machine tool, and more to a device and method for coordinating data acquisition of a machine tool / machine tool by multiple monitoring devices. Background technique [0002] Figure 1A It is a schematic diagram of a general machine tool / machine tool and its monitoring device, wherein the machine tool / machine tool 110 can be connected to a plurality of monitoring devices 121-123. Each of the monitoring devices 121 - 123 can send a remote parameter acquisition request to the machine tool / machine tool 110 in order to perform its monitoring purpose. Figure 1B It is a schematic diagram of a remote capture command sent by a monitoring device. Wherein, the remote parameter retrieval request is mainly a multiple periodic cycle retrieval request for multiple parameters, such as the parameter retrieval requests A, B and C in the figure. Wherein, the retrieval request at the remote end...

AI Technical Summary

Problems solved by technology

[0003] However, under the conventional technology, when the monitoring devices 121-123 send remote parameter acquisition requests to the machine tool / machine tool 110 at the same time, it is often impossible to expect the machine tool / machine tool 121-123 to reply to each parameter acquisition request. order

In addition, since the machine tool / machine tool 110 can only respond to one parameter acquisition request at a time, some parameter acquisition requests are accidentally ignored, or all parameters in a cycle cannot be completely obtained.

This situation will cause the monitoring devices 121-123 to be unable to stably obtain correct values ​​of all parameters of the machine tool / machine tool 110 in a complete cycle, and then make wrong judgments
