- Abstract:
-
In view of the specific conditions of serious electromagnetic interference, harsh environment, complex installation conditions, large data communication and strict requirements for the timeliness of data processing, according to the basic principle of cyclic redundancy check code (CRC), a table drive algorithm is designed to realize cyclic redundancy verification. The algorithm is implemented in the central processor with Delph 4.0 macro assembly and in the front end machine with MCS-51 microcontroller assembly language, and the two are portable to each other. Due to the software implementation of CRC’s table-driven algorithm, the system does not need to design additional hardware circuits, which reduces the cost, reduces the equipment installation size, verifies very quickly, and improves the communication speed and message transmission accuracy of the remote monitoring network.
