Title:
PROTECTION CIRCUIT AND CONTROL SYSTEM OF PROGRAMMABLE LOGIC CHIP
Document Type and Number:
WIPO Patent Application WO/2019/148470
Kind Code:
A1
Abstract:
Disclosed are a control system and a protection circuit thereof, wherein an input terminal of the protection circuit is connected to an output terminal of a central processing chip; an output terminal of the protection circuit is connected to an input terminal of a programmable logic chip; a control terminal of the protection circuit is connected to a feedback terminal of the programmable logic chip; after the programmable logic chip finishes loading a program, the control terminal of the protection circuit receives a second feedback signal from the feedback terminal of the programmable logic chip, the protection circuit generates a second control signal according to the second feedback signal and a first control signal, and the programmable logic chip receives the second control signal and stops receiving the program according to the second control signal. The present application is capable of preventing a programmable logic chip from re-loading a program due to the failure of a central processing chip, thereby preventing the failure of an entire control system and ensuring the safety of the operation.
