The atomic time scale release system for multiple laboratories is completed by modular design according to the atomic clock data provided by eight domestic punctual laboratories. The system includes the three modules, the processing of atomic clock data, the calculation of atomic time scale and the release of atomic time scale data, using MATLAB for data processing and time scale calculation, and using GUI for data visualization design. The system has clear process of the algorithm, simple function modules and friendly human-machine interface. The operation results of actual data show that the time difference between the integrated atomic time scale of the system and UTC is better than ±10ns, and the content of data release can meet the needs of the scientific research in related fields in China.
