Electrical control system for high-temperature hydrolysis process

Abstract

The invention discloses an electrical control system for the high-temperature hydrolysis process. The electrical control system mainly comprises an ARM module, an FPGA module, a parameter storage module and a terminal execution component, wherein an upper computer sends control parameters to the underlying ARM module through a communication interface; the ARM module stores system operating parameters in the parameter storage module; the ARM module further receives a start command of the upper computer, then an ARM chip module and a FPGA chip module invoke corresponding execution parameters from the storage module so as to enable the terminal execution component to execute corresponding commands. The conventional control system relies on the upper computer too much, and has poor real-time performance and universality, so that great difficulties are brought to application personnel. The electrical control system provided by the invention is based on a large-scale integrated circuit system, and through comprehensive use of two different types of chips, an ARM chip and an FPGA chip, an algorithm is embedded into a hardware system, so that on one hand, the efficiency and the accuracy ofhardware execution are improved, and on the other hand, the universality of the system is improved.

Description

technical field [0001] The invention relates to the field of automatic control of analytical instruments, in particular to an automatic control system for high-temperature hydrolysis. Background technique [0002] As a kind of experimental pre-treatment equipment, the high-temperature hydrolysis device uses the traditional control method to control needle valves, on-off valves, injection pumps, combustion furnaces and other equipment through different control interfaces or control protocols. This control method is cumbersome and real-time And the versatility is poor, which brings great difficulties to the application personnel, and is also not conducive to the combination of high-temperature hydrolysis equipment and subsequent analysis equipment such as ion chromatography. This system is based on a large-scale integrated circuit system. Through the comprehensive use of two different types of chips, ARM and FPGA, the algorithm is embedded into the hardware system, which speed...
