Market demand
The development of the real-time automatic monitoring system for the water environment of sewage outlets has just started in my country. Some developed countries in Europe and the United States have become mature in this regard. For example, some industrialized countries such as the United States have installed relevant monitoring instruments in almost every sewage outlet. Automatic monitoring of the operation status of sewage and sewage flow, PH value, DO, conductance, candle degree, temperature, etc., and the discharge of pollutants at the sewage outlet can be known at any time in the monitoring center. In Korea, 50% of the enterprises have achieved real-time automatic monitoring of the following four indicators: the operation of sewage treatment equipment, flow, PH value and dissolved oxygen. At present, most of the water environment monitoring in my country is mainly based on chemistry. That is, artificial regular (or irregular) on-site sampling, testing, and water quality analysis. This kind of workload is large and random, and it cannot accurately reflect the change process of the entire water quality and quality, so it cannot be a reliable basis for water environment assessment and environmental governance.
solution
This system adopts the combination of short-range ZigBee wireless communication and GPRS long-distance communication technology. The field collector is directly connected to Helicomm’s IP-Link2200 series products through the RS232 or RS485 interface, and the data is transmitted to the near-end monitoring center (factory) through the ZigBee wireless network composed of IPLink2200; and the ZigBee network in each area is connected to an MA8 (GPRS terminal), transmit the data to the remote monitoring center (environmental protection bureau) through the GPRS network, so that the factory and the environmental protection bureau can reasonably grasp the pollution index of the sewage discharged by the factory in a timely manner and prohibit the discharge of excessive sewage in a timely manner. in order to avoid greater losses. ZigBee technology, low power consumption, low cost, and no communication costs, make the near-end wireless mesh network more convenient to use; in addition, the MA8-9ib connected to the far end has a message buffering mechanism, so that the remote center can get the factory emissions in real time at any time. Sewage data, making sewage monitoring more convenient and comfortable.
