The working principle is as follows:
the numerical control machine tool uses a FANUC 31I-B system, and a relevant automatic shutdown program is added into a PMC program carried by the numerical control machine tool to realize an automatic shutdown function.
The PMC program is added with a no-operation identification program, a no-operation prompt alarm program and a no-operation automatic shutdown program, and then an alarm information compiling program is added to further facilitate the identification of technical operators, and the Chinese character content of the alarm information is converted into hexadecimal codes, so that technicians can check the Chinese character content in the system.
The no-operation recognition program can sequentially scan the states of all input points, such as a machining program, a starting input state, a resetting input state and other programs are located at corresponding R0622.5, R0622.6 and R0624.7 addresses in the PMC program, the PMC program further comprises numerical control machining programs such as a tool setting program, a tool changing program and a stopping program and other instruction inputs, the no-operation recognition program scans the states and the instruction input states of the programs sequentially and continuously in a circulating mode, if any working state or input state cannot be monitored within 120 seconds, the numerical control machine tool is judged to be in an idle and non-working state, the programs enter a no-operation prompting alarm program, meanwhile, the system collects the address information of the programs in the non-working state, and stores the information in a new address, such as R6023.7, so as to record and search.
In the no-operation prompt alarm program, the alarm display contents are as follows: "the device will automatically shut down without long-term operation". During the alarming period, the technical operator can relieve the alarming state through the reset alarming program, if the alarming state lasts for more than 120 seconds, the no-operation automatic shutdown program is started, and shutdown operation is carried out on the numerical control machine tool.
Finally, the system sends alarm information: the Chinese character of 'automatic power-off is about to be converted into hexadecimal coding without long-term operation of the equipment', which is convenient for technical operators to check.
And after the automatic shutdown program is completed, the processing capacity of the PMC is utilized, the relevant program is compiled to monitor and identify the unmanned operation information relevant to the numerical control system, namely the working state of each machine program, and then the information is processed and a processing result is given.
Under the condition that the numerical control machine tool is unmanned for a long time or is unattended, the numerical control machine tool can be automatically shut down without manual shutdown, the electric energy can be saved when the machine tool is shut down, the optimization of machine tool equipment management is facilitated, and the management efficiency is improved.
