Description
Technical field
The utility model provides a kind of Distributed Control System (DCS) fastener calibrating installation.
Background technology
Distributed Control System (DCS) (DCS) has been widely used in the production run of industries such as power plant, chemical industry, to the production automation of relevant enterprises and institutions and production run automatically control play crucial effects.The Distributed Control System (DCS) fastener is a requisite visual plant in the Distributed Control System (DCS).The principle of work of fastener is that the standard output signals (generally being microelectronics signals such as mA, mV, resistance) of field instrument output is delivered to the fastener input terminal in the dcs rack at a distance through lead; The high-low level signal (being commonly called as 0,1 signal) that becomes to calculate function identification through fastener conversion back is linked in the computer of dcs active station, thereby on computer display screen, demonstrates parameters such as on-the-spot pressure, temperature, flow, liquid level.Seeing that from principle of work fastener has played the vital role of forming a connecting link, is an important ring of enterprise production robotization.The security protection that the whether accurate directly influence of fastener conversion is produced, data statistics (comprising the energy measurement data statistics), cost accounting etc.At present, whether the big bulk measurement fastener of simple machine that each relevant enterprise just provides with the Distributed Control System (DCS) installation enterprises breaks down, and whether the class of accuracy of fastener is met the requirements detect and go deep into calculating.Energy unit energy measurement utensil is equipped with and energy measurement utensil (the containing fastener) class of accuracy of management general rule (GB17167-2006) 4.3.8 money (obligatory term) energy unit should meet the demands.The class of accuracy that calculates fastener will detect or calibrate fastener, will carry out standard and utility appliance to the examination criteria device and make and be strict with and test item and detection method are made specific requirement.
At present, whether enterprise more pays close attention to fastener quantity and satisfies and produce needs, and the metering performance of fastener is not caused enough attention.Also there is not fastener examination criteria device in the prior art, new through looking into, do not carry out this both at home and abroad and approve and initiate a project or study.
Summary of the invention
To above-mentioned prior art, the utility model provides a kind of Distributed Control System (DCS) fastener calibrating installation, and it can be used in judges the fastener class of accuracy, better meets the needs of energy measurement management and energy-saving and emission-reduction, promotes economic development.
The utility model is realized through following technical scheme:
A kind of Distributed Control System (DCS) fastener calibrating installation; Comprise casing, multi-functional standard electronic signal generator, oscillograph, pulse signal output appearance, voltage generation circuit, current generating apparatus, electromagnetic field tester and earth resistance tester; Wherein, multi-functional standard electronic signal generator, oscillograph, pulse signal output appearance, voltage generation circuit, current generating apparatus, electromagnetic field tester and earth resistance tester all are located in the casing.
The output of said multi-functional standard electronic signal generator mainly is winding displacement output (about 20 strands); Per two strands are a group; Be divided into red line (positive pole) and black line (negative pole), mainly contain mA winding displacement output interface, mV winding displacement output interface, Ω winding displacement output interface, Hz signal output interface.
As long as it is just passable that the realization of the function of said oscillograph, pulse signal output appearance, voltage generation circuit, current generating apparatus and earth resistance tester leaves the connection terminal that can realize corresponding function.
Said electromagnetic field tester can not established connection terminal, whether satisfies the fastener operate as normal and requires just passable as long as can demonstrate electromagnetic intensity around the fastener.
During use; Be connected with computing machine; Detection method is: the signal output part line that breaks off fastener and field instrument; With the input end of little electric signal such as (class of accuracy should more than 0.05 grade) electric current (4-20mA) of the calibrating installation outputting standard of the utility model, voltage (mV level), resistance, frequency to fastener; The actual numerical value of watching computer display screen to demonstrate, the contrast of actual displayed numerical value and standard input value calculates the error that fastener produces, thereby judges that fastener whether can operate as normal and whether coincidence loss requirement.
At present; When detecting in the prior art; Common practice is to import standard signal [little electric signal such as electric current (4-20mA), voltage (mV level), resistance, frequency] one by one to each Distributed Control System (DCS) passage to contrast the computing machine video data then; The device of the utility model then once is input to some passages of the same type according to type of signal source [like (4-20mA) etc.] simultaneously, contrasts the data of respective channel then one by one, and whether error in judgement meets the requirements; Can increase work efficiency, can also detect the stability of video data in certain period simultaneously.Whether this device can also other performance index of comprehensive detection fastener meet the requirements.
The utility model can be judged the fastener class of accuracy, better meets the needs of energy measurement management and energy-saving and emission-reduction, promotes economic development.
