Realization of Multi-functional Heat Pump Control System based on network

The hardware structure and software realization methods of a multi-functional heat pump control system based on network is introduced. The corresponding heat pump controller, water pump controller and customer control board are designed in combination with the heat pump control, logic, the practical equipment structures and installation environment. RS- 485 bus or CAN bus is adopted to realize communication. Various kinds of anti-interference measures is introduced into the system. They make the system have better adaptability to the changes of the environment. The high-efficiency control of the complicated functions is realized with the polling multi-task scheduler and the algorithm control of the software timer. Therefore, the resource of the micro controllers is saved. The performance and functions of the system were proved by the long-term testing of the basic functions, non-loaded and loaded testing.
