The current heating heat transfer stations mostly artificial control, while a waste of manpower; Other hidden dangers in the event of an accident when the operators found it difficult and cause equipment accident. Meanwhile, the heat transfer stations operate independently, the heating system is difficult to achieve the best overall state and cause thermal imbalance affecting heating effects caused great waste of energy. In particular, the central heating pipes, wiring cover large geographical area, dynamic real-time production data requirements, cabling difficult to achieve real-time continuous monitoring of pipelines and cables intermediate station and the user endpoint data, the central dispatch room to improve the monitoring capability and rely on the past, the traditional approach is difficult to meet demand.
For such across geographical, points scattered detection monitoring system, based on the GPRS wireless network of automatic control system, heat exchanger to achieve the parameters of the station site acquisition, the dispatch room with the heat transfer of data from real-time communications control, is an ideal remote monitoring solutions.
System :
The entire heating network remote monitoring system as illustrated by three components : the scene to control heat transfer stations, GPRS data transmission, dispatch room data centers. Through the control module and the DTU sanctioned GPRS data interactive. PLC data will be regularly sent to the sanctioned GPRS DTU, while receiving real-time PLC DTU made to the data from the corresponding control functions. Sanctioned GPRS DTU received PLC made to the data will be immediately transmitted to the data center.
Based on the GPRS network, the thermal control system effective network solutions to other forms of communication exist various problems. GPRS data through communications with the control center to achieve centralized heating network system running the real-time monitoring, timely and effective operation of the network to access data for the heating pipe network-quality volume reconcile provide scientific basis for boiler room control system can be timely, transparent access to network operating information to facilitate the achievement of boiler running economy. Reliable communications system, good stability and low cost. Friendly interface, simple operation can realize powerful communications functions, computing functions, query, print, to really improve work efficiency.
The dispatch center network, network servers and factory MIS network connections, is responsible for the heating network to the various operating parameters online MIS for MIS on a corresponding software for data analysis, data mining and other functions, greatly enhanced heating network operation economics.
System features :
GPRS always-DTU a boot will automatically attached to the GPRS network, and data center and the establishment of communication links, at any time user data transceiver equipment data with the real-time high.
Operating costs have been low GPRS DTU online, according to send and receive data packets to the number of charge, no flow of data transmission without charges or monthly unlimited use manner.
High-speed transmission GPRS network transmission fastest to reach 160Kbps, the rate depends on the level of mobile operators network configuration, according to China Mobile's network, now available in 20 to 40Kbps data transmission stability.
Group net simple, fast, flexible GPRS wireless DDN system through the Internet anytime, anywhere covers all of China Mobile Virtual Private Network data communications for medium-sized and small users with access, access savings investment.
Communication links by professional operators to maintain due to China Mobile's GPRS data services, maintaining links by China Mobile also responsible for maintaining communication links remove worries for the future.
Lightning due to China Mobile's GPRS data services, without affecting the Internet, under the premise of GPRS DTU very small transmitter power, antenna is very short, but not elevated to overcome the cable transmission and radio transmission easy primer bad lightning equipment shortcomings.
