Supervisory Control System

This research designs a web-based supervisory control system based on Raspberry Pi. The system consists of one Raspberry Pi single-board computer and multiple data acquisition modules. The sensing and driving of the system are completed by reading/writing those data modules through RS485 interface by Modbus RTU protocol. Embedded database is used to store input/output data. Embedded web server provides interface for remote monitoring and control. The system was applied to environment control for computer room. It monitors air-conditioning systems, room temperature and humidity, fire alarm systems, uninterruptible power supply (UPS) systems, electricity supply systems and door access control systems. If something happens, it can drive buzzer, alarm, voice dialing, or air conditioning. The focus of this paper is using software to integrate hardware available in the market to form a low cost reliable supervisory control system.

Supervisory Control System

This research designs environment supervisory control system of computer room which consists of multiple Android environment controllers and one supervisory control server. An Android environment controller is a controller based on Android device. The controller contains an Android device, a Wi-Fi wireless access point, a switch hut (or NAT) and three data acquisition modules. The Android device enters TCP/IP LAN through the Wi-Fi access point. The data acquisition modules with TCP/IP interface are plugged into the LAN, and read/written by the Android device with Modbus TCP/IP protocol. Control logics are designed for computer room environment control. The controller monitors air conditioning systems, room temperature and humidity, fire alarm systems, uninterruptible power supply (UPS) systems, electricity supply systems, leak detections, and door access control systems. If something happens, it can drive buzzer, alarm, voice dialing, or air conditioning, send SMS, voice mail, record audio, or video. A supervisory control server is used to help remote controls of all Android environment controllers. All Android controllers send their operation data to the server. Authorized user can login to the server to monitor and control certain Android controller with a browser or Android device.

This paper designs a web-based Android supervisory control system. Android controller is used as a local controller to fit into a supervisory control framework. The framework includes a central server, a SMS device attached to the server, multiple local controllers, a remote control program and a ladder logic computer-aided design program. The Android controller contains an Android mobile phone, a Wi-Fi wireless access point, a switch hut (or NAT) and multiple data acquisition modules. The Android mobile phone enters TCP/IP LAN through the Wi-Fi access point. The data acquisition modules with TCP/IP interface are plugged into the LAN, and read/written by the Android mobile phone with Modbus TCP. The Android controller communicates with supervisory server with a specific m2m protocol which is based on http protocol. Once an Android controller is connected to the supervisory control framework, it can be monitored and controlled remotely with any browser. A web-based home security system is constructed to demonstrate the usage of the web-based Android supervisory control system. The control laws for the home security system are partially implemented with ladder logics designed with a computer-aided program in the framework. With a supervisory server serving multiple Android controllers, Cloud home security service is formed.

This paper designs a web-based Arduino supervisory control system. Arduino controller is utilized as a local controller to fit into a supervisory control framework. The framework includes a central server, a SMS device attached to the server, multiple local controllers, a remote control program and a ladder logic computer-aided design program. The Arduino controller contains an Arduino USB board and an Ethernet shield. The USB board provides basic input/output and processing power, while the Ethernet shield provides TCP/IP connection capability. The Arduino controller communicates with supervisory server with a specific m2m protocol which is based on http protocol. In this paper, the http protocol and m2m protocol is fulfilled based on TCP connection in an Arduino controller. Once an Arduino controller is plugged into the supervisory control system, it can be monitored and controlled remotely with any browser. The web-based Arduino supervisory control system is used to provide remote supervisory control service of water pumping systems of multistorey buildings scattered in big Taipei area by a small company.

Operation And Management

In this paper, the substation computer supervisory control system structure, content, features and characteristics were described. In recent years, substation monitoring technology has been developed rapidly, and has been widely used. However, due to the promotion of our country is in its infancy, technology is not mature, the new operation and management model is being explored, and thus in the operation also exposed some problems.
