The data from the on-site monitoring instruments for pollution source treatment is collected and processed by the data acquisition and transmission instrument, and sent back to the receiving server of the Environmental Protection Bureau's monitoring center through GPRS wireless data terminal or ADSL China Telecom broadband network. The monitoring center software of the Environmental Protection Bureau parses the received data according to the communication protocol and stores it on the central database server to achieve synchronous monitoring, recording, and processing of data by the monitoring center. The monitoring center software of the Environmental Protection Bureau can automatically monitor multiple signals based on the setting of data alarm volume, reducing dependence on personnel and achieving unmanned operation.
