Description
Technical field
It the utility model is related to as instrument DCS rack automation fields, be specially a kind of by setting up thermometric, temperature control member
Part, realize that device is even controlled in the cabinet room environment temperature alarm of the unattended cabinet room temperature monitoring warning function of tradition.
Background technology
Distributed Control System abbreviation DCS, it can also literal translate as " scattered control system " or " distributed computer control system ".
The fundamental design idea that it is disperseed using control, operation and management are concentrated, using the autonomous structure type of multi-layer classification, cooperation.
It is mainly characterized by its centralized management and decentralised control.DCS obtains in all trades and professions such as electric power, metallurgy, petrochemical industry at present
Extremely it is widely applied.
Instrument DCS system cabinet room environment temperature requires that control range is smaller, and environment temperature is too high or too low all will to be
System stable operation causes fatal harm.Because of situations such as design and factory personnel lack, constituent parts occur more unattended
Cabinet room, only by the various refrigeration of indoor location and heating equipment, field condition can not be met.In practical situations both, people is safeguarded
The regular visit of member often makes cabinet room temperature control, so as to cause to block in cabinet room with checking room ambient conditions Shortcomings
Part failure.
Alarmed therefore it provides one kind realizes that unattended DCS racks room temperature monitors in operator station, prevent temperature control device
Failure rear rack room temperature is exceeded, the device to be damaged to system, has been a good problem to study.
The content of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides one kind and realizes unattended DCS racks
Room temperature is monitored in operator station and alarmed, and prevents that temperature control device failure rear rack room temperature is exceeded, the machine to be damaged to system
Cabinet room environmental temperature alarming even controls device.
What the purpose of this utility model was realized in：
A kind of cabinet room environment temperature alarm even control device, including DCS system 3, the temperature detection being connected with DCS system 3
With converting means, system software configuration 8, temperature control device device and active station 5；
Described DCS system 3 is DCS controllers；Temperature detection includes detector unit 1 with converting means, with temperature
The RTD cards 2 that detecting element 1 connects, RTD cards 2 connect DCS controllers；
Described temperature control device device includes temperature control device 7, the DO cards 6 being connected with temperature control device 7；DO cards 6 connect DCS controls
Device processed；
Described DCS controllers connection interchanger 4, the attended operation station 5 of interchanger 4.
Positive beneficial effect：The utility model can utilize different DCS systems, give a kind of cabinet room environment temperature alarm
Even control device, the problem of overcoming unattended cabinet room temperature over-range, produce following technique effect：1st, rack room temperature is taken
Into DCS system, realize and rack room temperature is monitored in real time.2nd, instrument DCS racks room temperature indicating alarm device utilizes DCS systems
System, investment reduce.3rd, instrument DCS racks room temperature instruction alarm is realized in operator station, without increase special messenger.4th, DCS racks
Room temperature indicating alarm device control program, can flexible configurations according to production process.The device refers to instrument DCS rack room temperatures
Control significant.
Brief description of the drawings
Fig. 1 is device block diagram of the present utility model；
It is in figure：Detecting element 1, RTD cards 2, DCS system 3, interchanger 4, active station 5, DO cards 6, temperature control device 7, system
Software configuration 8.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is described further：
As shown in figure 1, a kind of cabinet room environment temperature alarm even control device, including DCS system 3, is connected with DCS system 3
Temperature detection and converting means, system software configuration 8, temperature control device device and active station 5；
Described DCS system 3 is DCS controllers；Temperature detection includes detector unit 1 with converting means, with temperature
The RTD cards 2 that detecting element 1 connects, RTD cards 2 connect DCS controllers；
Described temperature control device device includes temperature control device 7, the DO cards 6 being connected with temperature control device 7；DO cards 6 connect DCS controls
Device processed；
Described DCS controllers connection interchanger 4, the attended operation station 5 of interchanger 4.
Temperature is introduced DCS, realizes that temperature is supervised in real time in operator station by the utility model using DCS system resource is produced
Control；
Described temperature introduces DCS：DCS has thermal resistance passage, is measured using thermal resistance；DCS only has AI passages, uses
Temperature transmitter measures.Monitoring is described temperature in real time：Configurating operation person station displays temperature numerical value, configurating operation person, which stands, to be carried out
Temperature over-range sound and light alarm prompts to adjust with linkage.
Described DCS system is transferred to cabinet room after production scene data are converted by field instrument, is pressed in controller
Program prepared in advance is automatically controlled, or carries out people's machine information exchange in operator station；Described temperature detection and conversion
Device is：Rack room temperature is transformed to DCS acceptable signals by temperature element according to known corresponding relation, is sent into control
System；Described system software configuration is：The temperature detection for accessing DCS system is turned with converting means signal by software programming
It is changed into the numerical value that operator easily monitors to show, carries out alarm if necessary and carry out signal through DCS system output element
Transmission；Described temperature control device device：It is the equipment such as air-conditioning, central air-conditioning that will be linked through DCS system output signal.
Embodiment 1
