Research Of Multiple Function Test And Control System Based On Digital Laboratory

Nowadays, the great roles of the laboratory played in science research work have made universities afford a lot to laboratory construction. With the development of computer technology, the digital laboratory is a new study object in fields of laboratory construction. Under the current situation of capability and management of experimental equipments in laboratory, this paper brings forth the project to build a digital laboratory system, and discusses the realization methods in detail. Following is the main woke about the paper:1. By analyzing the conception and models of digital laboratory, the total layout design about building a digital laboratory is given; with the field bus techniques, the Layered Bus Topology is put forward to meeting the need of network laboratory.2. The hardware of the digital laboratory system design. MFMC (Multiple Functions Main Controller), the key of network laboratory, has been designed in this part, which inspects and controls experimental equipments.3. The software of the digital laboratory system design. The design of embedded software of MFMC and the communicating protocols about all communications in digital laboratory system are included in this part. With reference to XMODOM protocol, the method of communication of the Layered Bus Topology is also proposed in this part.4. The software for computer inspecting and controlling facilities is designed, and the sliding bearing test-bed is given as software demo. Combining with the MFMC, the software has been practiced and improved,5. Test of the whole system. After constructing the system, a test is taken to secure the reliability of the whole system.
