Circuit board with interlocking function

Abstract

The invention discloses a circuit board with an interlocking function. The circuit board comprises a PCB main board and an encryption board integrated on the PCB main body. A signal input module, a signal output module and a switch module are arranged on the PCB main body. A panel communication transmission module, a CPLD control chip, an MAC storage chip, a CNC signal transmission module, a voltage amplifying module and a circuit assisting protection module are arranged on the encryption board. The panel communication transmission module is connected with an external operation panel. The CNC signal transmission module is connected with a CNC controller. The external operation panel judges whether an operation panel is matched with the encryption board through the panel communication transmission module after calculation through the CPLD control chip. The external CNC controller is output through a signal output module through the voltage amplifying module after calculation of the CPLD control chip through the CNC signal transmission module. According to the invention, the interlocking function between the operation panel and a machine tool signal circuit board is achieved; proper usage of the device is normalized; rights and interests of producers are ensured; and safety of the device is further improved.

Description

technical field [0001] The invention relates to the field of numerical control systems, in particular to a circuit board with an interlocking function. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system. From the application point of view, CNC machine tool is to express various operations and steps required in the processing process through digital codes, and to send digital information through the control medium. Into the computer, the computer processes and calculates the input information, and sends out various instructions to control the machine tool. At present, the parts produced in single or small batches account for more than 80% of the total mechanical processing, and they occupy a very wide market. [0003] In the CNC machine tool, the calculation and execution of various instructions of the CNC device are completed by operating the CNC operation panel. At present, the CNC operation panel has realized ...

AI Technical Summary

Problems solved by technology

[0003] In the CNC machine tool, the calculation and execution of various instructions of the CNC device are completed by operating the CNC operation panel. At present, the CNC operation panel has realized the lock code function. code to prevent it from being maliciously used or damaged, and the corresponding CNC machine tool control box has not yet realized the lock code. Normal work, on the one hand, this situation is not conducive to the manufacturer's integrated management of the entire CNC system structure, on the other hand, it is also not conducive to the user's operation in accordance with the regulations, which is likely to cause potential safety hazards, so provide an interlocking and mutual authentication The circuit board is of very far-reaching significance
