ABSTRACT Low temperature double circulation generator is the latest product which can successfully change low grade heat energy into electricity. There will be a great significance for energy saving and environment protection. It will also promote the research of Chinas new generator, but there is a risk of quality. In order to ensure the quality of the low temperature double circulation generator, some tests of the performance parameters before delivery is necessary. So the development of platform for the low temperature double circulation generator is meaningful. This paper sets up a platform for the low temperature double circulation generator. The platform is mainly composed of cold and heat source system, monitoring system and detection system. The cold and heat source system provides the runtime environment for the generator.The monitoring system is mainly used for collecting data, such as temperature, flow rate and heat volume. The detection system is mainly used for testing the power consumption parameters. This topic utilizes computer, sensor and testing technology to build a set of high accuracy, high automation platform .We also design the software for the platform. The monitoring system equipped with AI board, DI, DO card and PCI-485 board with the PC as the core. The temperature data acquisition card, heat meter, multi-function power meter constitute the distributed data acquisition and control system based on RS485. The software design selects Visual Basic 6.0. Through the serial communication MSComm, we could realize real-time acquisition and storage. We choose ACCESS as a database for data storage. The software has the characteristics of friendly interface and it is easy to use. After completing the system debug, the platform could realize stable running. There is a good control of temperature, flow rate. Through the analysis for the operation parameters, we could not only determine whether the generator is qualified, but also find the disadvantages
