Principle of work of the present utility model is:
In the SIM card deck of gas meter, flow meter, be inserted with the SIM card of having paid the fees of buying from public network operator; When work, gas meter, flow meter timing with short message mode, is sent to metrical information the computer center of gas company by SMS communication module by Virtual network operator.
the difference of short message mode of the present invention and conventional wireless communication mode is:
Gsm system is global system for mobile communications (GlobalSystem forMobileCommunication), it is the network standard of second generation wireless digital cell mobile communication systems, it has defined the various standards of building this network and service being provided, these standards are administered by ETSI (ETSI), normally used frequency is 900MHz, 1800MHz, 1900MHz.The ability of the communication services such as the speech business of providing, fax, note is provided GSM mobile radio communication, wherein SMS is because wide coverage, input cost are low, high reliability, being suitable for designing some wireless application systems and product, can requirement of real time be the needs of very high small data business;
Gprs system is general packet radio service (General PacketRadioservice), it is a kind of new bearer service growing up on gsm system basis, it has broken through GSM network can only provide the Circuit-switched mode of thinking, by increasing corresponding functional entity and existing base station system being carried out to part transformation and realize packet switch, GSM (note) and GPRS(concentrator wireless remote transmission---conventional radio meter register mode) key distinction of meter reading method shows:
1) utilize GSM network to realize radio meter register fairly simple, it is made up of gas meter, flow meter base table head, data acquisition module, gsm module and Surveillance center, data acquisition device module and Surveillance center connect GSM network by gsm module, with the form of note, data are sent to Surveillance center by GSM network.
2) kilowatt meter reading-out system based on GPRS is made up of gas meter, flow meter base table head, data acquisition unit/concentrator, GPRS module, Internet network and Surveillance center, data acquisition unit or concentrator and GPRS module communicate by serial ports, the data of collection are sent by GPRS network, and then access Internet network, finally be transferred to Surveillance center, realize remote meter reading; Wherein, in the time that communication has just started, first GPRS module initiates to connect Surveillance center, and Surveillance center obtains after necessary information from the packet of receiving, both could set up communication.Surveillance center accesses GPRS network by Internet, need to adopt DDNS, and the technology such as address mapping, could realize seamless link.
In sum, installation, configuration and the technical requirement of GPRS than GSM complexity many, generally need could arrange with reference to relevant handbook, the SMS(ShortageMessageService of both implementation method GSM) point-to-point short message service is the business of GSMPhasel standard definition, it is by the transmission of proprietary control signal channel, short message is stored by short message service center (SMSC), and forward and (start shooting in the time can transmitting, in service area etc.), and transmission adopts dedicated channel, reliability is very high, but transfer rate limits to some extent.Can use Block pattern, Text pattern and PDU pattern to its control, no matter which kind of mode, its length that sends data is restricted, therefore SMS is applicable to the transmission of small data quantity, GPRS adopts packet-switch technology, having broken through GSM adopts Circuit-switched dedicated channel to transmit the mode of data, to data (Packet) transparent transmission of packing, therefore multiple users can utilize same wireless channel to transmit simultaneously, improve the utilization factor of Internet resources, but network very easily blocks up, data are easily lost.GPRS carries ICP/IP protocol, can access Internet at a high speed, can transferring large number of data
The principle of work of the SMS of the scope of application GSM of the two and GPRS self and characteristic have determined their applicable situation and scopes separately, utilize the SMS of GSM to carry out data transmission, and system buildup and technical configuration are comparatively simple, easily realize.But be short message service due to what use, numeral or the letter of every note transmission mostly are 160 most, are applicable to small data quantity transmission and the not high occasion of transmitting-receiving frequency.But its delay time is longer, wanting art higher to real-time and transmitting-receiving frequency, the occasion that data volume is larger, its cost performance is by large heavy discount, no longer applicable, the principle of work of GPRS has ensured that it can support explosion type data transmission intermittently, can support again the transmission of mass data once in a while.Data rate is fast, charges by flow, and networking " always online " mode can ensure that communicating pair carries out exchanges data more fast in real time.Therefore the system based on GPRS is suitable for the complication system that this communication is frequent, data volume large, requirement of real-time is higher.
