In the Lineate direct-reading long-range transmission gas meter reading system, direct-reading gas meter is installed in the house (install method is the same with ordinary mechanical gas meter), the line of data transmission through the junction box connected to the outdoor system bus unit ,the system bus unit connect to the unit down stair. Finally, after collected and counted the data from user’s gas meter is send to data center Specific resolve Strategy 1. Data transmission method, use RS485 industry bus unit or MBUS meter bus unit. 2. The easiest method is use partly bus unit connect all meters of the unit to the collector, use the handset can direct-reading the data of meters. 3. Within certain range (a building), can connect gas meters directly to the concentrator by local bus. 4. If user amount is great, we must connect some amount gas meters directly to the collector by local bus, and then connect the collectors to the concentrator. 5. Gas Company can use the handset collect or reading the data of concentrator, and transmit the data to data centre of Gas Company. 6. The concentrator can transmit the data to gas company data centre automatically through the mobile GPRSnetwork
