Remote monitoring and fault diagnosing system for numerical control slitter and method for realizing same

Abstract

The invention provides a remote monitoring and fault diagnosing system for a numerically controlled slitter and a method for realizing the same. The system comprises a controlled end 1 of a numerical control system of the slitter, a transfer station 2 of a serial port server and a main control end 3 of a remote monitoring and fault diagnosing center server, wherein the controlled end 1 is controlled by an industrial computer PC / 104 and communicated with the transfer station 2 through an RS-485 serial port; and the transfer station 2 is communicated with the remote main control end 3 through the Internet network. The realization method realizes functions of remotely monitoring and diagnosing faults of the numerical control slitter by formulating a remote monitoring control strategy and a communication protocol. The system and the method have the characteristics of lowering maintenance cost of machines, shortening downtime and improving production efficiency.

Description

technical field [0001] The invention relates to a remote monitoring and fault diagnosis technology, in particular to a remote monitoring and fault diagnosis system for a digitally controlled paper cutter and an implementation method thereof. Background technique [0002] With the development of the economy and the advancement of science and technology, a large number of various CNC processing equipment are now appearing in small and medium-sized enterprises. Reduce labor intensity, improve production efficiency, and increase economic benefits. [0003] The usual CNC equipment has a set of diagnostic programs, which can check the status information of the machine. With this set of diagnostic procedures, we can find and eliminate various faults in time, isolate the fault to the module or device level, and minimize the downtime. However, this set of diagnostic procedures is essentially just a fault alarm system, which depends largely on human experience for fault diagnosis an...

Problems solved by technology

[0007] However, the communication of the Modem based on the PTSN public telephone network is greatly affected by channel interference, and data loss, code errors, and frequent disconnection often occur due to channel interference. Once the data is lost or error codes are frequently generated, remote monitoring cannot be realized, and it is even more impossible to make a scientific judgment on the failure of the paper cutter at the remote main control terminal through such erroneous machine operation status information.

Therefore, this method has low communication efficiency and weak stability, and cannot meet the data correctness requirements of the remote monitoring and fault diagnosis system of the CNC paper cutter, and cannot achieve the goals of remote monitoring and fault diagnosis.
