Abstract

The technique enables an operator to operate with different suppliers’ Remote Terminal Units (RTUs) or control systems with a uniform operator user interface via a mobile device. In this paper, we discuss methods and equipment to enable the local access and collection of well production data without the need to be hard-wired or otherwise physically connected to production equipment or a control system. In particular, we discuss the apparatus on using a universal operator interface to interact with RTUs/ control systems manufactured by different suppliers. The apparatus allows an operator to read measurements and write control commands through a smart tablet or other mobile devices to RTUs or other control systems through a Wi-Fi wireless communication link.

An Apparatus to Develop a Universal Operator Interface for Mobile Devices to Operate Control Systems/ RTUs from Different Suppliers

Abstract

Oil and Gas operation companies usually own an d operate control systems/ RTUs manufactured by different suppliers with di fferent hardware o r software version. These diffe rent RTUs u sually share common applications, e.g. plunger lift. They use th e same m easurements and execute similar control functionalities. However, each control system/ RTU has its own operation interface. This creates a few challenges from operation perspectives

 There is a sharp learning curve for operators to become skilled at one operator interface. The same operator may have to learn diff erent operator interfaces in orde r to execute the same operation functionalities with different suppliers' control systems;

 The same supplier will release new version/design of operator interface together with hardware upgrade imposing burdens on operation companies to l earn and adapt to a n ew operator interface.

We propose an apparatus to develop a universal operator interface for a m obile device to communicate and operate different Remote Terminal Units or other control systems that are manufactured by different suppliers.

The invention enables an operator to read and write data from a tablet to an RTU or other types of control system. The technology system hardware includes an RTU or other types of control system, a local Wi-Fi access point connected to the RTU or other types of control system, and a tablet, laptop or other similar mobile devices that can access the RTU/control system data via the Wi-Fi system. The technology system software will include software on the mobile device allowing communication via standard industrial communication protocols such as Modbus, TCP/IP, OPC, and others. A user-friendly operator interface allows the operator to use a grap hic user in terface to re ad and write data to and from the RTU. Additionally, the RTU and tablet or mobile device may be enabled to allow remote desktop access through the tablet or mobile device.

An operator using the technology system establishes communication between the tablet or mobile device and the Wi-Fi access point. The Wi-Fi acce ss point in the technology system is only connected to the RTU and is not connected to a separate network system. In particular, the list below contains specific hardware and software components.

For hardware, the system contains (as shown in Figure 1)
