The fuses and relays box test bench has two functions in trucks assembly factory: Description The fuse inspection test bench consists of: The fuse inspection test bench works in two modes: - LabVIEW Real-Time: refrigeration system with two temperatures
This system allows the study of refrigeration systems and the implementation of the thermodynamic calculations applied to refrigeration. Its uniqueness is that it is fully controllable via the Internet directly from a web browser like Internet Explorer or Firefox. It consists of two cold rooms, each with their own evaporator but sharing the same cooling fluid R134a system (compressor, condenser …). The control and configuration of this system can be done in two ways: The Compact Fieldpoint adds the possibility of remote control via the Internet, viewing the evolution curves of temperature, air and refrigerant fluid, pressure and power at various points. This allows calculating the required cooling system features such as enthalpy, entropy, Mollier diagram and performance coefficients. Hardware The software is embedded in a Compact Fieldpoint controller from National Instruments. It includes a RJ45 Ethernet connector that allows to connect to the network in aim of uploading the executable on the controller module to the embedded FTP and publish shared variables on the network. We use Compact Fieldpoint module inputs / outputs, analog and relays for sending commands (start / stop, compressor speed , refrigerant solenoid valves, condenser and evaporator fans, lights and heaters for cold rooms) and collect measurements. We measure the power consumed by the compressor with the power meter included in the regulator. This regulator communicates only by Jbus protocol. So we use the RS-232 Compact Fieldpoint controller and connect to it an RS-232 <-> RS-485 converter. Jbus communication functions are programmed into the controller based on the Modbus protocol that is compatible for our use. An Ethernet 8 relays card is added to increase the number of relays. Software How does it work? The user has the option to choose, by a switch, using the bench in local mode with the classical control panel or using… Read more: LabVIEW Real-Time: refrigeration system with two temperatures - LabVIEW: Weather station with a Pocket PC
