Embodiment approach 1

[0030] use figure 2 The structure of Embodiment 1 of this invention is demonstrated using the block diagram of FIG.

[0031] Numerical controller 100 according to Embodiment 1 of the present invention includes a monitoring unit 110 , a determination unit 120 , a monitoring mode selection unit 130 , a monitoring mode storage unit 140 , and a monitoring data storage unit 150 . Typically, the numerical control device 100 is an information processing device including a central processing device, a storage device, and an input / output device, and the functions of the above-mentioned processing units are logically realized by the central processing device executing a program stored in the storage device. . In addition, the numerical controller 100 can be communicatively connected to a machine tool (not shown), and can acquire information for determining an operating state and information on monitoring items from the machine tool or the like.

Abstract

A numerical controller capable of suppressing a load on monitoring processing by monitoring only necessary items according to the operation state of a machine tool or the like includes a monitoring pattern storage unit loaded with a monitoring pattern defined for each operation state of the device to be monitored, a determination unit configured to determine the operation state of the device to bemonitored, a monitoring pattern selection unit configured to acquire the monitoring pattern corresponding to the determined operation state from the monitoring pattern storage unit and create a monitoring list based on the acquired monitoring pattern, and a monitoring unit configured to monitor the device to be monitored based on the monitoring list and acquire the monitoring data.

Description

technical field [0001] The present invention relates to a numerical control device, and particularly relates to a technique for monitoring the state of a machine tool or the like. Background technique [0002] Numerical controllers are known that monitor the operating states of machine tools, robots, and other production equipment (hereinafter referred to as machine tools, etc.) for operation management and analysis. In general, items to be monitored vary depending on conditions such as the operation method and operation time of the machine tool, etc., and therefore involve many aspects. On the other hand, the hardware resources (for example, CPU, storage memory) of the numerical control device are limited. Therefore, it is technically difficult to monitor many items for a long period of time and to store monitoring results. [0003] In this regard, Japanese Patent Application Laid-Open No. 2007-004601 discloses a technique in which data processing and the like can be easi...
