Data collection transmission system and method for real-time monitoring of industrial process

The invention provides a data collection transmission system and method for real-time monitoring of the industrial process, and belongs to the technical field of data collection and transmission. The system comprises an electronic measuring instrument, a programmable logic controller, a local monitoring end, a cloud server and a mobile terminal. The system supports broadcast, multicast, subscription modes and the like simultaneously, and different business engineers can obtain needed data information via the subscription mode; the instantaneity and reliability of data transmission are improved, the bandwidth is reduced, and the flow needed in the data transmission process is reduced; and the response speed is high, data and information of a fault can be seen directly, the operation state of onsite equipment can be known at any time and place, and thus the system and method can be used by people with different requirements conveniently.
