Wireless distributed control system of special controller for ring die

Abstract

The invention provides a wireless distributed control system of a special controller for a ring die. The system comprises 1-N-numbered master monitoring control devices and a matched wireless distributed monitoring alarm device, wherein each master monitoring control device comprises a pickup, a signal processor, a high-speed analog-digital converter, a DSP (digital signal processing) microcontroller and a numerical control drilling machine controller which are connected with each other in sequence; the DSP microcontroller can carry out fast Fourier transform and speech analysis; the components of the master monitoring control device acquire a sound signal of a drill, then convert the sound signal to a digital signal and then carry out fast Fourier transform on the signal to obtain a real-time spectrum; a speech processing circuit of the DSP microcontroller constantly compares the real-time spectrum with a spectrum which is originally acquired and stored in the microcontroller and appears when the drill works normally; the matched wireless distributed monitoring alarm device is provided with a wireless transceiver module which emits an alarm signal and is provided with a receivingdisplay unit formed by the wireless transceiver module, a central control module and a central display template which receive and process the alarm signal and display an alarm. The system finds drilldulling in time, controls the drill to stop quickly, and can give an alarm to prompt a user of replacing the drill in time.

Description

technical field [0001] The invention relates to the monitoring and control technology of a numerically controlled drilling machine, in particular to the monitoring, controlling and alarming technology of the drill bits of the ring die numerically controlled drilling machine. Background technique [0002] The ring die CNC drilling machine has changed from one drilling machine per person to eight or ten drilling machines per person, and its efficiency has been greatly improved. It seems that no one is required to operate it, and the labor intensity should be reduced a lot. However, with the operation of multiple drilling machines, the drill bits are rapidly worn out. As long as they become worn out, drilling will become difficult, the quality of drilling holes will not be guaranteed, and accidents may even occur; things. In order to avoid this phenomenon, as long as the drill bit becomes dull and makes dull noise, the operator must immediately rush to the drilling machine to ...

However, with the operation of multiple drilling machines, the drill bits are rapidly worn out. As long as they become worn out, drilling will become difficult, the quality of drilling holes will not be guaranteed, and accidents may even occur; things

In order to avoid this phenomenon, as long as the drill bit becomes dull and makes dull noise, the operator must immediately rush to the drilling machine to brake the machine and change the drill bit to ensure the safety of the drilling machine and the workpiece and the quality of the drilled hole; and the drill bit The change occurs randomly, so that the operator is always in a state of high tension when working, and people are prone to fatigue, which is extremely unfavorable to safe production
