Problems solved by technology

[0002] The current data collectors basically use RS485 or RS232 data bus for remote data transmission. Although these solutions can collect data, they have common shortcomings in application: (1) The data transmission using the bus cannot be shared with the computer network In the existing wiring system, rewiring will increase the construction cost; (2) The data collector collects many parameters on site and the data volume is large, and customers need different types of data, so the data collector cannot transmit data to different data Center, must rely on multiple collectors to cooperate to achieve this function, increasing the cost of customers
