Description

A kind of environmental analysis instrument

Technical field

The present invention relates to the environmental analysis instrument, particularly a kind of design that can detect a kind of environmental analysis instrument of or several indexs to be analyzed simultaneously.

Background technology

The workflow of environmental analysis instrument generally can be formed with the redirect principle combinations in sequence by pre-service, feed liquor metering, reaction control, assay determination, data processing, demonstration and these a few class subfunction flow processs of communication.At present, usually to adopt with a microprocessor or microcontroller be the control core system to the environmental analysis instrument that detects a kind of analysis indexes.For example: the arsenic on-line analyzer that Chinese patent application publication No. CN101900703A is announced, its control system core are single processor main board (parts 9:CPU shown in Figure 1).

Along with client's improving constantly to analytical instrument function modoularization, module intellectuality, beautiful interfaceization and grid requirement, employing is that the drawback of core control system just highlights gradually with a microprocessor or microcontroller, and it has mainly showed these points:

The one, the reliability of flow process and beautiful interface and the gridization contradiction on single control system: the control flow of environmental analysis instrument is more complicated all generally, relate to the valve group, the pump group, the control of various actuators such as detecting device and sensor, for guaranteeing the reliable and stable of flow process control, industry all adopts at present with PLC, the embedded microcontroller of technical grades such as single-chip microcomputer is the control system on basis, but, this class control system is having inborn weak tendency aspect interface output and the gridization, realize the colored large-size screen monitors of meeting customer need, the communication interface of interactive interface efficiently attractive in appearance and many standards, its cost of development is very big or infeasible technically.On the other hand, on interface and communication function, have the control system based on universal personal computer, industrial computer processor or embedded microprocessor of advantage, in stable control, but seem unable to do what one wishes numerous actuators and sensor.

They are two years old, under the framework of this uniprocessor control system, if break down in certain part of environmental analysis instrument, then need replacing is diagnosed or safeguarded to The whole control system, simultaneously, in the time need carrying out local improvement or device replacing to instrument, the hardware and software of total system all needs to adjust, and the extendability of system is poor.

They are three years old, because the detection principle of various environmental analysis instruments has nothing in common with each other, its functional module and analysis process be difference to some extent also, so instrument of on this uniprocessor control system framework, developing, its control system separately on the hardware and software mutually between versatility not high, for the new environmental analysis instrument that needs exploitation, the reusability of existing mature technology is poor, and the R﹠D costs of new instrument are higher.

In addition, detect more than one index to be analyzed if desired simultaneously, adopting with single microprocessor or microcontroller is that the system architecture of core control system is in the design of software and hardware with safeguard that difficulty is very big.Therefore, detect the application demand of more than one index to be analyzed simultaneously for need, prior art solutions normally can detect several analytical instrument of each analysis indexes and treat as the slave computer transmitter, adopt field bus technique that each analytical instrument is integrated as independent particle system and form an analytical instrument system.In this system architecture, the analysis process of each analytical instrument is write by the outside, and be in operation by the controller Autonomous Control of this analytical instrument subsystem inside, host computer only is responsible for assigning and is detected instruction and obtain the analysis result value that subsystem returns behind certain hour.At present, this control system is widely used in the integrated design of the environment of many indexs or pollution source on-line monitoring instrument.Adopt this system architecture still to have 2 deficiencies in environmental analysis instrument application field:

The one, still higher to hardware requirement as each analytical instrument subsystem controls system of slave computer, must be the interactive interface of each analytical instrument subsystem design user interface and input and output on software and hardware, this will increase the exploitation and the production cost of each analytical instrument subsystem undoubtedly.

They are two years old, can only provide some limited based on the control system software architecture of simple integrated technology such as beginning to measure, begin upper stratas such as demarcations, the instrument return data instruction interfaces of countercharging, and present monitoring water quality on line requires the user can be by wired or wireless network remote countercharge each device or bottom operation under each analytical instrument subsystem usually, and existing control system can't satisfy the countercharge demand of device level bottom operation.
