The organization of gas data collection.<\/strong><\/p>\n

Gas (water) \u00a0metering \u00a0in \u00a0an apartment of the consumer is carried out by means of the meter with a pulse output. The meter is equipped with the radio module with dry contact.<\/p>\n

As \u00a0the \u00a0communication \u00a0environment \u00a0indoors \u00a0using \u00a0\u00a0local \u00a0radio \u00a0network. \u00a0Further, in the area \u00a0from the house to the data collection center as the physical medium for communication using GSM\/GPRS.<\/p>\n

 <\/p>\n

Application<\/strong><\/p>\n

Meters can communicate directly with the concentrator. \u00a0\u00a0However if conditions of audibility appear worse admissible, radio modules carry out functions of repetition.<\/p>\n

 <\/p>\n\"123\"<\/a>\n

 <\/p>\n

Some variants of data transmission in the Center are possible:<\/strong><\/p>\n

* GSM – the \u00a0concentrator \u00a0is \u00a0completed \u00a0with the \u00a0GSM \u00a0modem \u00a0and \u00a0data \u00a0are \u00a0passed \u00a0to \u00a0the \u00a0Center.<\/p>\n

* Data \u00a0\u00a0\u00a0\u00a0transmission \u00a0\u00a0\u00a0\u00a0periodically \u00a0\u00a0\u00a0\u00a0from\u00a0\u00a0\u00a0 \u00a0\u00a0concentrator \u00a0\u00a0\u00a0to \u00a0\u00a0notebook \u00a0\u00a0through \u00a0\u00a0\u00a0USB\u00a0\u00a0 \u00a0interface.<\/p>\n

* Data transmission one times in a month from the radio module to terminal of manual data \u00a0gathering on the radio-channel (Walk-By, Drive-By). \u00a0\u00a0By \u00a0this \u00a0principle \u00a0it \u00a0is \u00a0possible to get data \u00a0from radio modules established at the separate consumers. Direct access to meter unit is not required.<\/p>\n

 <\/p>\n

The advantages<\/strong> of solutions based on radio:<\/strong><\/p>\n

* Automatic meter reading radio increases the speed of data collection from meters<\/p>\n

* The\u00a0 reliability\u00a0 of\u00a0 the\u00a0 data\u00a0 is\u00a0 greatly\u00a0 improved\u00a0 due\u00a0 to\u00a0 the elimination\u00a0 errors\u00a0 in \u00a0data\u00a0 recording \u00a0or transmission.<\/p>\n

* Reading of the radio also opens access to all the counters, even in cases where the consumer is not in place or if the meter is in a remote place.<\/p>\n

 <\/p>\n

Technology<\/strong>\u00a0<\/strong><\/p>\n

* Frequency range 433MHz does not require a license.<\/p>\n

* Thanks\u00a0 to\u00a0 the\u00a0 new\u00a0 technology\u00a0 module “D100-F” also works reliably in harsh environments and in the presence of interference<\/p>\n

* D100-F\u00a0 provides\u00a0 accounting,\u00a0 recording\u00a0 in\u00a0 memory\u00a0 and\u00a0 the\u00a0 transmission\u00a0 of\u00a0 impulses consumption<\/p>\n

* Every day radio transmits consumption data to the concentrator.<\/p>\n

* The radio allows the issuance of additional data:\u00a0 time stamps and events of radio modules and sensors<\/p>\n

 <\/p>\n

Ease of<\/strong> deployment<\/strong><\/p>\n

* No cost for the design.<\/p>\n

* No cost for laying communication cables.<\/p>\n

* The radio modules and pulse the sensors is easily installed on the gas meters.<\/p>\n

* Does not require any work on the setting up and configuring the system – all done automatically.<\/p>\n

\u00a0<\/strong><\/p>\n

Advanced Features<\/strong><\/p>\n

* Daily readings for accurate billing, even in cases where the owner of the apartment was replaced<\/p>\n

* Leak detection by analyzing the hourly charts of consumption, creating additional savings for energy consumers<\/p>\n

* Transfer the alarm if necessary, for regular battery replacement<\/p>\n

* Sending alarm when unauthorized access to the pulse sensor<\/p>\n

* The system may be used to accommodate different kinds of energy by connecting to the electricity meters, water or heat.<\/p>\n
