Design of high-speed data acquisition and management system for negative ion source

Negative ion source usually needs to collect the systems' operation information that can be useful for optimizing its design. In this case, the data is fast updating and uploaded through the Ethernet but the data storage operation is time-consuming. Regarding this process, it can also easily lead to data loss when multi-subsystems are uploading data concurrently. Aware of this issue and aiming to solve it, a three-level structure is proposed - each of them with an independent module for every subsystem. The first level is the hardware level that can sample and upload data to the second level through UDP. Further on, the acquired information is transferred from the second base using ZMQ. After the test, ZMQ application could solve the problem of the mismatch between the uploading speed and the storage speed, effectively reducing data loss.
