Embodiment Construction

[0032] A specific embodiment of the present invention can be realized in this way.

[0033] 1. PC104 system realization:

[0034] In order to achieve figure 1 The PC104 module in the system can use the well-known PC104 board produced by Shengbo Company as follows.

[0035] 1. The model of the CPU module is: SysCentreModule / SuperDX CPU module (CPU is 486 or PII)

[0036] The CPU module includes all PC / AT compatible DMA controllers, interrupt controllers and timers. With extended industrial ROM-BIOS, 16M byte DROM and keyboard, speaker interface; in this system, the commonly used PC external keyboard is not used. Because the external PC keyboard is easy to generate weak sparks at the plug interface and keyboard keys, which is not conducive to explosion protection. Instead, a membrane keypad attached to an electrical box filled with positive pressure protective gas is used to improve explosion-proof performance. The keyboard is connected to the keyboard interface of the CPU ...

Abstract

Present invention discloses integrated plant chromatograph observe and control system. It contains Temperature detection and amplifying circuit, signal conditioning circuit, ISA bus compatible PC 104 module, said PC 104 module consisting of CPU, memory, bus circuit, A/D and D/A conversion circuit, network card, display card, keyboard interface, clock, I/O interface circuit and high-speed universal asynchronous transmitter-receiver URAT interface circuit, and analog input/output port. High-speed universal asynchronous transmitter-receiver connects with epistasy computer, temperature detection and amplifying circuit amplifying circuit connected with A/D circuit and analog input port in PC 104, analog output port in PC 104 outputting connector through D/A conversion circuit, according to PC 104 computational result to realize temperature control and spectra hump identification, and converting analytical result into 4-20 mA standard industry simulating signal. Said invention raises systematical operability and maintainability, reducing misoperation resulting from double-computer mode.

Description

technical field [0001] The invention belongs to a measurement analysis control system of an intelligent on-line analysis instrument for measuring the component content of a mixture, in particular to a computer measurement and control system of an industrial gas chromatograph. Background technique [0002] Petroleum, chemical, steel and other industries are the lifeblood of a country. It not only plays a supporting role in the entire national economy, but also plays an important role in improving a country's national defense strength. The industrial chromatograph is a large-scale process analysis instrument widely used in these industries. Industrial chromatographs are used to analyze the composition and content of gas and liquid process samples in the process of industrial production on-line. The analysis results are used for direct quality inspection of the process computer control system. Because industrial chromatographs are mostly used in ...
