Abstract
The invention provides a turbidity detecting instrument including: a controller including an input module, a main control module connected with the input module, a display and key module connected with the main control module, a storage module connected with the display and key module, an output module connected with the storage module, a control module connected with the output module, and a power supply module for providing continuously stable current and voltage for each module in the controller; and a sensor connected with the input module through a cable.
Description
Technical field
The present invention relates to a kind of turbidity measuring instrument.
Background technology
At present, along with the rising of people's living standard, China's municipal effluent disposal of pollutants produces the harm that can not estimate to rivers,lakes and seas, and improvement is polluted very urgent.The objectionable impurities of polluted-water comprises organism, inorganics, has naturally in artificial, and form has gas, liquid, suspension, emulsification, dissolving, colloid, and kind is many and complicated.Domesticly carry out at present water quality detection and must carry out in different laboratories multinomial numerous and diverse test, differentiate and detect respectively, expense is high, the time is long, so the import of advanced technology improves detection and processing horizontal is very necessary.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of turbidity measuring instrument, overcomes various problems in the turbidity detection technique, as accuracy of measurement is not high, stability is unreliable, unit is few, the response time is long, measurement range is little, the way of output is single; It is little that this product has the product maintenance amount, the output of Chinese numeral, function-stable, the characteristics that precision is high.
To this, the invention provides a kind of turbidity measuring instrument, comprising:
Controller comprises: load module, be connected main control module with described load module, the demonstration that is connected with described main control module and key-press module, the storage module that is connected with key-press module with described demonstration, the output module that is connected with described memory module, the control module that is connected with described output module, power module that continual and steady current/voltage is provided for described modules; And sensor, be connected with described load module by cable.
Adopt technique scheme, after switching on power, power module provides continual and steady current/voltage for the quality detector; When sensor being placed in corresponding occasion, load module therefrom reads relevant data through sensor; Then load module passes to analysis and the further senior calculating of carrying out data in the CPU main control module to the data that comprise in signal source again; By showing with key-press module, current value is represented to the user with display screen finally, the menu editing function is provided simultaneously, the user can use button to revise voluntarily some parameters and configuration according to oneself requirement.Display screen can provide numeral and Chinese character output to facilitate the user to read; Final data is stored by the storage module record.Simultaneously, output module uses HART, and the agreements such as PROFIBUS or electric current output are transferred to outside PC or programmable logic controller (PLC) with current data and parameter and carry out focusing on of data.
Compared with prior art, the invention has the advantages that the on-line continuous measurement that realizes turbidity, left unguarded, realize real automatic water quality monitoring system.Sensor carries and cleans the scraping blade function, but all fouling products on timing automatic wiping sensor probe surface make the product maintenance amount very little.The way of output of controller comprises: 4 to 20mA industrial standard electric currents, 0 to 20mA industrial standard electric current, MODBUS digital communication agreement, PROFIBUS digital communication agreement, or HART digital communication agreement.The accessible measurement range of instrument is 0 to 10000NTU, minimum resolution is the sensor of 0.001NTU.Instrument is by 110 to 220VAC ac power supplies, and optional 24VDC powers, and service area is wide.Instrument can show numeral, Chinese character, English,, by the thin film switch of 8 buttons, can easily to all parameters in instrument, arrange.The turbidity detector is widely used in: in the water in waterworks, municipal wastewater factory, chemical plant, stream field, lake, river, turbidity detects.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, more excellent embodiment of the present invention is described in further detail:
As shown in Figure 1, controller 1 comprises: load module 11, be connected main control module 12 with described load module 11, the demonstration that is connected with described main control module 12 and key-press module 13, the storage module 14 that is connected with key-press module 13 with described demonstration, the output module 15 that is connected with described memory module 14, the control module 16 that is connected with described output module 15, power module 17 that continual and steady current/voltage is provided for described modules; And sensor 2, be connected with described load module 11 by cable.
After switching on power, described power module 17 provides continual and steady current/voltage for the quality detector; When described sensor 2 is placed in corresponding occasion, described load module 11 reads through described sensor 2 data that detect; Then described load module 11 passes to analysis and the further senior calculating of carrying out data in described main control module 12 to the data that comprise in signal source again; By showing with key-press module 13, current value is represented to the user with display screen finally, the menu editing function is provided simultaneously, the user can use button to revise voluntarily some parameters and configuration according to oneself requirement.Display screen can provide numeral and Chinese character output to facilitate the user to read; Final data is stored by described storage module 14 records.Simultaneously, described output module 15 uses HART, and PROFIBUS or electric current output protocol are transferred to outside PC or programmable logic controller (PLC) with current data and parameter and carry out focusing on of data.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
