Embodiment 1

[0039] see Figure 1-10, a programmable oil well wellhead controller, which includes a processor, a data memory, a program memory, a data communication interface, an RS485 bus communication interface, a ZIGBEE wireless interface, an analog signal input circuit, a switch signal input and output circuit, and a voice controller and audio power amplifier; the data memory and the program memory are connected to the processor, and the two memories are used for data interaction, program download and program debugging with an external host computer; the data communication interface is connected to the processor Connected, the data communication interface is used for the transmission of operation data; the RS485 bus communication interface is connected with the processor, and the RS485 bus communication interface is used for communication with the frequency converter and the intelligent power meter unit; the ZIGBEE wireless interface is connected with the processing The ZIGBEE wireless...

Embodiment 2

[0054] When programming the programmable oil well head controller in the first embodiment, the system adopts a real-time operating system, built-in protocol stack and file system, etc., and the software is written in C language. The system has a built-in IEC61131-3 running, downloading, and debugging environment. Through the Ethernet port, the controller can be programmed. The programming environment and operating environment support five types of programming defined by IEC61131-3: IL, LD, ST, FBD, and SFC. language. The programming environment converts the five programming languages ​​defined by IEC61131-3, IL, LD, ST, FBD and SFC, into intermediate codes, which are then compiled into machine codes by the compiler and can be directly run on the processor.

Abstract

The invention discloses a programmable oil well mouth controller and a control method thereof. The well mouth controller comprises a processor, a data storage device, a program storage device, a data communication interface, an RS485 bus communication interface, a ZIGBEE wireless interface, an analog quantity signal input circuit, a switching value signal input and output circuit, a voice controller and an audio power amplifier. The data storage device and the program storage device are used for data interaction, program downloading and debugging. The data communication interface is used for data transmission. The RS485 bus communication interface is used for being in communication with a frequency converter and an intelligent electric quantity instrument unit. The ZIGBEE wireless interface is used for being in communication with a well site controller. The analog quantity signal input circuit collects load and walking beam angle data. The switching value signal input circuit is used for detecting whether a cabinet door is closed or not. The switching value signal output circuit is used for controlling a contactor. The voice controller is used for playing prompt voice. The programmable oil well mouth controller is high in reliability and convenient to expand, remote data collection and control can be achieved, and the requirement for personnel safety is met.

Description

technical field [0001] The invention relates to a programmable oil well head controller and a control method thereof, belonging to the field of oil well control in oil fields. Background technique [0002] With the aging of my country's oilfields and the increase in personnel costs, in order to reduce personnel costs and labor intensity, various oilfields are promoting the construction of digital oilfields. In the digital oilfield construction, the digital construction of the oil well is the basis of the entire digital oilfield. [0003] At present, the wellhead controllers in oilfields have many disadvantages, such as poor reliability, single function, inconvenient user expansion, and need to use the manufacturer's upgrade program to realize the functions. [0004] Therefore, a new wellhead controller is needed, which can realize remote data acquisition and control in oil fields, as well as personnel safety, wireless communication, energy saving and other needs. At the sam...
