Brief introduction of DCS-D3 centralized distributed quantitative loading Control System
DCS-D3 centralized distributed quantitative loading control system is an intelligent system which is spot quantitative loading controller focused, resolving the phenomenon that the slow of loading and low of accuracy of oil and chemical in loading process, preventing emerging from tank and bad grounding, etc. This system has the features of high accuracy, fast response and high security. It could connect with flowmeter, liquid level switch, temperature instrument, grounding switch, control valve, and control the auto-loadingof truck and train trestle, it is applicable to the enterprise of oil, chemical, refining oil, etc, to realize spot quantitative loading control and centralized management of the control room.
The system realizes loading and quantitatively loading for barrel, compensates temperature automatically, and uses explosion-proof materials to make the system safe and reliable. Spot quantitative loading controller could be installed near the loading trestle work. Spot staffs could operate and keep watching on grant materials. Control room takes concentrative monitoring and management to the whole trestle by industrical computer, composing a genuine distributed controlling system. The system allocates neatly, and could fully satisfy the different clients’ requests.

Function:
The function of data collection and disposal
On-treatment and analysis are applied to the controlling signal of impulse, grounding, anti-overflow, and valve, etc, sending the data upto epigynous machine. And the epigynous machine stores up the data.
The function of safely alarming
During or before loading, if system detects the bad static grounding, it will alarm automatically and shut down the truck in time or refuse to load. If system detects the activity of liquid switch in the process of loading, it will stop loading at once and to alarm.
The function of simulation displayed
In the process of loading, System could simulate scene to display the state of loading , valve and the state of grounding. Making it convenient for the operation staff to learn the state of loading in the work field.
|
The function of competence management
This system has set triple competence: the class of operation staff, the class of administrator and the class of engineer. Operation staff could operate with loading work; administrator could inquire about, back up and recover the data; engieer could set the parameters of system.
The function of inquiry, printing and collection of the data
During operating, the system builds the data dacument of loading and log document of operation The clients who have the competence of administrators could inquire about the data at any moment. Make out the related bill of document according to the needs of clients’.
The recording function of operation log
During the system’s operation , it records the operating content of workers automatically, in order to keep on a file and inquiry by the administrators.

The brief introduction of DCS-D4 Data monitoring system in the storage farm
DCS-D4 Data monitoring system in the storage farm bands the IPC, ADAM and various types of meters in the field work which are high performance and high reliability togethor to implement the share and harmonize of various parts of signal and finish the system of the synthetic measure and control and administration. Be applicable to the management of process and control of various storage and transportation equipment of oil tank.
DCS-D4 Data monitoring system in the storage farm composes by administrative operator station, some processing station and polling apparatus to finish the display of craftwork parameter detected of the collection of tank data and administrative system, display control of device state detected and printing table of information stored refered, etc. Software system of system mainly constitudes configuration exploitation software system and running software system. Configuration exploitation composes KING VIEW and EXCEL. Running? software system compaoses DDEI/O, KING VIEW running working procedure and EXCEL running report program.
Main functions:
The function of signal detection and in formation processing
Real-time detect and dispose to analog quantity of signal in the tank field area.
Judge whether abnormal condition will happen or not.
Send out the audible and visual alarm to the important parameters of out- of –limit condition.
Remind the post operating workers of noting and affirm.
The function of onscreen display
Onscreen display is classified as detecting and measuring instrument onscreen display, PFD, display control of device state detected, trendline record onscreen display, collection of warning messages onscreen display, operating button onscreen and auxiliary display, etc. Onscreen display is audio-visual, strong colour, concise operation, and devices mainly display by animation.
The function of dynamic renovation of data
Dynamic renovation of data is classified as numeric point, state point, and stick figure point, etc.
The function of recording trendline
The system could have a function of trendline recording to analog quantity.
The function of operation protection
To prevent nonauthoritative people from operate the measurement and control, the system has a warning hint to error operating, and sets password protection in an important operation at the same time to ensure the safety of the system.
The function of report forms
According to the request of client, make various kinds of report forms and content.
Report writers are classified as automatic timer and artificial random ---two kinds of printout options.
The function of on-line parameter adjusted
The system could empower to online amend to kinds of detected points such as range, high/low limit, unit, and magration, etc.

RLC-D3 quantitative loading controller
RLC-D3 ration loading controller is the core of DSC-D3 control system, realize loading of liquid material and ration loading barrels and apply to control truck and train loading in the field work..
RLC-D3 uses 16 bit processor, answers for the request of anti broken of field work and realize network connections to detect loading by CAN. |
|
The features of function:
Use 16 bit processor, miniaturization and intelligentization.
Flameproof of type designed, safety and reliable.
Realize pulse flowmeter to input.
Temperature compensated automatically, set parameters in the field work, and realize to load rationally.
Control 4 sets of valves and pump control, and sequence of operation could be programmed.
LCD display the state of valve, liquid level switch, grounding switching and information of fault state.
Have the function of antistatic, control of anti liquid spilling.
Field apparatus, communication and meter isolate by P/F.
Technique data:
It could connect 4 valves at one time, and program control, RLC-D3 providing 24 volt DCA.
Collection flowmeter to send square wave or sinusoidal waveform of pulsing signal.
Use 4-20 milliampere Pt100 platinum to compensate temperature.
Connect with various kinds of liquid level switch including current mode, voltage type and passive.
Connect with various kinds of usual electrostatic grounding devices.
Precision of controlling loading reaches 0.2%.
|
Function introduction:
Ratinal loading
Set the capacity of loading anf send out valve control signal to realize the rational loading.
