The software for regional automatic center stations plays an important role in the detection of automatic stations. However, because the software provided by different equipment manufacturers is different, the unified version software is developed, which realizes that equipment from different manufacturers can be connected to the united data collection platform. The communication module is the core in the whole unified edition software. It is the bridge between equipment and general control module that can analyze the data from the equipment correctly and submit them to the master control module packaged in the united format and the order correctly from the master control module and then send to the corresponding equipment. The communication module is based on the concept of layering and modularization. The design uses the macro analytic and multi threading technology comprehensively. It realizes the united access with the equipment from many manufacturers in the communication layer.
