Tank is usually in the large number of control valves and scattered, the general information contained in the control valves and wiring less variety, which at a certain extent so that the design of tank monitoring system complicated. The system uses the company's UK Rotork intelligent electric valve and its master station controller, monitoring system greatly simplifies the complexity of the design, but with its wealth of diagnostic information and fault tolerance, so that system reliability can be improved. 2 Monitoring and Control System hardware implementation 2.1 Rotork intelligent valve control equipment Rotork intelligent valve control equipment is a valve data acquisition, monitoring and control system, which consists of a master station controller and its connected to on-site electric valve components. Master station controller through a two-line current loop can be controlled in the loop on the peg up to 240 control valves at the scene, the current loop can be up to 20 km. Intelligent electric valve at the scene of a higher degree of its in-house rich in data and diagnostic information. But the most important characteristics are a number of smart valve only two lines through the Internet into a loop, and ultimately access to the main station controller, only the start and the end of two lines, all the valves via a two-line communication information into the master controller. Electric valve at the scene also has the line fault shielding, when the emergence of open-loop, short circuit or ground fault, the smart valve failure can be masked side lines, so that the main line station controller still with all the smart valve communications without the impact of failure information will be distributed simultaneously master controller. Normal operating circumstances, the communication loop current signal along a line from the main station controller outflow port A, through the back loop from the port B. At this point, another line is redundant. When there is a line failure, there has been fault line valve shielding, fault lines on both sides of the smart valve could loop through their communications with the master controller; when there are two lines failure, failure of these two between the smart valve have been shielding, two fault outside the smart valve can still through two "arm-like" loop with the master controller. Master station controller are from the main CPU card, loop communications card, power supply, LCD display and 16 button keypad mounted disk, composed of intelligent instruments. It has two fixed internal database, a database unit are at the scene, responsible for receiving and recording from the two-line loop from the address of the smart valve, torque, such as opening the data sent from the PC to read and write command exercise control valve, the database is logically divided into four zones, each zone valve 60 Record data; other database-oriented station controller status and self-diagnosis database for records of communications protocol and the relevant state issued an order to the smart valve. Through the master station controller buttons and LCD display, you can read the smart implementation of the opening of valves, torque, address and other data, control the opening and closing valves, receive alarm signals and communications with the PLC functions. Pakscan IIE Master Station Master Station Rotork are a controller, it prepared for the hot double structure, the main controller in the event of a failure can automatically switch to the hot spare controller. Pakscan IIE Master Sation has an RS-485 communications port and a RS-232 communications port, which can be through the Modbus communication protocol with the PLC. One of RS-232 communications port can be directly connected through the PLC printers, print alarm signal. 2.2 Monitoring and Control System Structure The system control part of the United States the use of GE Fanuc's HBR dual hot-type PLC systems, PLC control through the valve 140 smart (IQ actuator) to open the close-out. Host monitoring station can monitor all the smart valve return valve position, and valve position value and the alarm signal, and the implementation of open valves, stop valves and valve clearance operation. Pakscan IIE master station controller and PLC using Modbus protocol between the communication to port 1 of the RS-485 interface connector. Normal operation, the main PLC and the host controller from the PLC controller and hot prepared separately with the main PLC and the host controller to maintain synchronization. Intelligent valve feed data to the main controller, the main PLC through RS-485 interface from the main controller to read data, and its decree, the main controller and then the implementation of orders, according to an order-driven operation of the smart valve. When the master PLC or host controller fails, the system automatically switches to separately from the PLC or controller hot prepared. Because of the system are used in Modbus communications protocol, a PLC can connect multiple Pakscan IIE master station controller, therefore, if the scene more intelligent valve, the system can be easily extended and easy to connect. 3 Software Design 3.1 Communications Programming PLC optional Modbus RTU Master communications module (master). Pakscan IIE master station controller is a remote terminal unit, as a Modbus slave (slave). PLC's CPU through the Modbus RTU Master communication module control Pakscan IIE master station controller to read and write, known as the Modbus host. Modbus host system uses a single two-line communication, which means you can connect a maximum of 32 Pakscan IIE master station controller. The main communication module programming has 3 parts: initialization communication module; reading and writing Modbus / RTU data; to monitor the communications status. Communication modules are configured to initialize the work of three main control block to initialize the parameters: Slave Control Block (SCB), information control block (MCB) and communication requirements of parameter block (COM_REQ). SCB is a register length of 15 data blocks, functions are defined with their Slave communication model, the number, status and other parameters, each Slave necessary to define a block SCB. MCB is a six register long data blocks, function definitions are required for each Slave Executive Master of the order information, including the command type, RTU reference address offset, PLC reference address offset, host No. parameters, each command required MCB define a block. COM_REQ register 17 are a long data blocks, function definitions are means of communication, ports and control words SCB and MCB monitoring the status of parameters, each port need to define a block COM_REQ. All of these initialization parameters in the PLC on the electric or cold start initialization of the first scan cycle loaded into RTU Master communications module, since RTU Master Communication Module is responsible for PakscanIIE master station controller and communications, while the PLC with the RTU Master communication module to exchange data. Reading and writing Modbus / RTU communication data and monitoring the status of the programming is relatively easy, as long as the definition of reading and writing initialization parameters corresponding PLC address. 3.2 Monitoring software design Host monitoring station can accurately monitor and control the storage and transportation process of all the information and equipment. Through programming, configuration, connectivity, vividly reflect the actual process to show dynamic data, set PID control parameters and process parameters, and can view the historical trend, alarm history, etc. Report. Rotork electric valve configuration of the scene at the oil flow line, through the button to manually start, stop and turn off any valves, and display any time the status of the valves and valve position value. Well-designed man-machine interface to enable simple, intuitive.采油车自动监控系统的设计摘要 针对目前油田采油车自动化程度低和局部操作不方便等缺点,从更好地控制采油车的整个工作过程出发,开发了一种较先进的采油车自动监控系统。该系统可实时显示起下载荷、深度、速度;使用霍尔传感器可测得滑轮转速;利用单片机可计算得到下入深度或上升距离;通过使用应变测量技术测得钢丝绳的张力,可计算出载荷大小。控制箱是该系统的核心部件,它与气控执行部分相连,可实现对刹车、离合器的控制,并能根据各使用方所要求的不同参数,更改程序相关参数,实现对采油车的灵活控制。关键词:采油车,自动监控系统,控制箱,霍尔传感器,应变Design of Automatic Monitoring System for Trailer Mounted Pumping UnitAbstractSince the existing trailer mounted pumping unit is inconvenient to operate, an automatic monitoring system is developed.
