Running-water Company and gas company rely on manpower to carry out copy reading to water consumption and gas consumption for a long time, efficient is extremely low, and the main manpower that relies on of meter reading data statistics, the report generation cycle is long, analysis of statistical results is slow, obtain result and can not reflect in time that system's consumption demand distributes, the network optimization of supply system is not had reference value; Moreover data to copy the fetch cycle longer, the table that can't obtain all users of synchronization counts, and makes the ambiguity with inexactness and time period of obtaining of table meter table data, causes the spatial and temporal distributions of consumption, the credible result degree is not high.
Summary of the invention
For the problems referred to above, the utility model provides a kind of Automatic meter reading system that utilizes the wireless network transmissions data.
The Automatic meter reading system that the utility model provides comprises and shows meter, concentrator and main website that described table is counted photoelectric direct-reading intelligent meter meter, and the table meter is connected with concentrator by the M-BUS bus; Be provided with wireless module and GPRS module in concentrator, be connected with main website by wireless network.
Described table meter is direct reading remote watermeters or direct-reading remote transmitting gas meter.
The table meter adopts the photo-electronic directly reading technology directly to read window value, and without cumulative errors, its electronic section is not worked at ordinary times, and only in meter reading moment work, system failure rate reduces greatly, and life of product is longer, works more reliable.The direct-reading remote transmitting gas meter need not initialization, and the kilowatt meter reading-out system maintenance workload is little, has valve control function, guarantees the safety of charging.The table meter adopts the M-BUS bus to be connected with concentrator, does not distinguish both positive and negative polarity, completes simultaneously data communication and table meter power supply function is provided.Concentrator can carry out the wireless remote communication with main website by modes such as GPRS public networks and be connected, and also can connect by the RS-485 bus, can receive main website command execution corresponding operating, and upload data to main website.Concentrator can be according to main website order Real-time Collection and timing acquiring data, and the timing acquiring cycle can arrange from 2 minutes by 1440 minutes.
Table meter and concentrator also can be by RS-485 wired or RF wireless mode be connected, during wireless connections, concentrator can realize that wireless meter counts collection or wireless mode maintenance by wireless module, wireless communication distance is greater than 500m, the communication success ratio is greater than 99%; Can pass through trunking scheme expanding system communication distance according to field condition.
The main website of system is based on Microsoft Windows operating system and Office Design of Software Platform, has the operation interface of hommization, is to integrate the overall treatment software of checking meter, showing to count management and toll administration.Main website also can be by the data dump of handheld unit with each data concentrator by carrying out various operations to the concentrator transmitting order to lower levels.
Main website of system background manage software provides abundant Data View and interface flexibly, can conveniently network with marketing system or the other system of power department, realizes data information sharing.
The utility model adopts photoelectric direct-reading table meter, directly the copy reading table counts, and is uploaded to concentrator by the M-BUS bus mode, and concentrator utilizes wireless network that table is counted and is transferred to the main website of system, can receive simultaneously the setting parameter of main website, realize the automation remote monitoring of kilowatt meter reading-out system.
