Embodiment
Referring to Fig. 1, GSM data transmission system of the present utility model comprises: the gsm wireless communication network; Centre information system; A plurality of front end data acquisition equipment are distributed in the working site, are used to gather non-electric charge quantity signalling, and non electrical quantity is converted to electric quantity signal; A plurality of GSM data transmission sets, the input of each GSM data transmission set is connected with the output of corresponding front end data acquisition equipment respectively, its output is connected with the gsm wireless communication network, be used to receive, analyze, encode and encapsulate the electric quantity signal that front end data acquisition equipment is exported, the signal after will handling at last sends to centre information system by the gsm wireless communication network.
Front end data acquisition equipment comprises measuring transducer and data acquisition system, it is responsible for some non-electrical signals such as rainfall, temperature etc. are changed into analog electrical signal, become digital signal after analog electrical signal is sampled through A/D and enter the GSM data transmission set, the GSM data transmission set is actual to be an embedded computer system, it finishes steps such as analysis to sampled data, coding, encapsulation, at last it is sent to centre information system by the GSM net, centre information system just can be made corresponding processing according to these data.
The GSM data transmission set mainly adopts a singlechip CPU as central processing unit, circuit such as program storage and data storage have been expanded in the outside, and the serial port of having expanded a full duplex is connected with the gsm wireless transmitter module, and the serial port that CPU carries then directly links to each other with front end data acquisition equipment.
Divide according to working method, this equipment has two kinds of working methods: the first, and artificial data is gathered transmission means; The second, the automatic data acquisition transmission means.First kind of working method is applicable to that the scene has the staff, can carry out manual operation, after triggering manual transmission data switch, this equipment makes an immediate response, get measurement data from the front end data collecting device, and through sending to the centre information system of far-end after the necessary processing.This mode is suitable for some more urgent situations such as flood-peak stage is monitored, and the field personnel need report the data of some instantaneous variation to the center; Second kind of working method is not need personnel to arrive the monitoring scene, is applicable to the monitoring to fixed target.In this mode, can be divided into according to the acquisition mode of data again regularly from two kinds of newspaper mode and remote command polling modes.From the newspaper mode is every interval certain hour (this time can be set), send measurement data by the GSM data transmission set from the trend centre information system, this kind mode generally is applicable to normal monitoring, for example: monitor headend equipment as rainfall in a certain basin with this GSM data transmission set throughout the year, monitor the rainfall situation of this area every day, and regularly send measurement data to centre information system; The remote command polling mode is meant that centre information system at any time can assign data transfer instruction to this GSM data transmission set, make this far-end radio transmission apparatus that up-to-date measurement data is beamed back the center, centre information system can carry out poll according to the numbering of far-end, also can specify certain specific remote equipment to send data continuously, as oilfield exploitation, front headquarter (centre information system) can be under certain time poll in every day the well data and the fuel-displaced situation of each drilling team, or in the fuel-displaced serial command remote equipment collection and beam back data when unusual of certain mouthful of oil well.
Divide according to the mode that sends data, this equipment comprises dual mode again: a kind of is the short message mode; Another kind is the data channel mode.The short message mode is meant the related protocol of this equipment according to GSM, and the mode of measurement data with short message sent to centre information system.Characteristics are cheap, simple but real-time is poor, and the manner can be used on normal measurement, do not emphasize the occasion of real-time, and the rainfall monitoring system long-term as the somewhere as long as beam back local measurement data every day, and do not require correct time; The data channel mode is meant that this equipment sends the data channel of measurement data with the GSM net according to gsm protocol, be characterized in real time, fast, accurately, but cost is expensive slightly than the short message mode, mainly be used in urgent the time, arrive as flood peak, centre information system needs the instant water level situation of grasping, and just must use the data channel transmission means.These two kinds of data receiver formulas both can also can be set by the field personnel by the centre information system remote command.
The above various working methods of speaking of are all respectively had place to show one's prowess in actual applications.They all are identical on the know-why of data acquisition and wireless transmission, and its data flow and transmission protocol mode are as shown in Figure 2.
The M-BUS agreement is followed in communication between front end data acquisition equipment and the GSM data transmission set, is to realize by the serial port of a full duplex; In the GSM data transmission set, the computer embedded system comprises relevant short message mode and data channel mode two aspect contents in the gsm protocol with communication between the wireless transmitter module.Be complete two formula communication between centre information system, GSM data transmission set and the front end data acquisition equipment three, carry out the transmission of the order of data.
The concrete workflow of native system following (referring to attached circuit diagram): measuring-signal (data) enters native system by the P1 mouth, and CPU takes out measuring-signal and data are carried out error checking from serial ports, if error in data then abandon data and request repeat; After data are correct, just data are carried out the necessary processing conversion,, after these work are finished, just by the GSM transmitter module information is sent via the P2 mouth to be fit to the GSM communications protocol; When not launching work, CPU always is in the state of the receiving register of inquiry 16550, when the poll of finding to have centre information system is called out,, and the metrical information in the buffer issued centre information system by the path that has connected with regard to the demand working circuit.
The characteristics of GSM data transmission set are: utilized domestic existing wireless data communication network as far as possible, utilize its area coverage widely, make the use of this equipment not be subjected to the influence of territorial scope, whenever the data that collect can be sent to the rear remote server timely, to analyze and to handle.For any front end data acquisition equipment, only need change connection protocol slightly, just can adapt to new demand.
Referring to Fig. 3, GSM data transmission set of the present utility model comprises: a central processing module, the numerical data of receiving front-end data acquisition equipment output, and by short message format to the processing of packing of this numerical data; An asynchronous serial controller module, the short message parallel data that CPU is packed converts serial data to, and will convert parallel data to from the short message packet of gsm wireless communication network and give CPU; A wireless sending module is used for the serial data of asynchronous serial controller output is sent to centre information system through the gsm wireless communication network, and receives the packet that sends through the gsm wireless communication network; A hardware watchdog module, it improves the antijamming capability of system as monitor portion, is subjected to external disturbance and causes program fleet or system reset is restarted when crashing in system, and it also provides the function of hand-reset simultaneously; A decoding circuit carries out address decoding when for CPU system function module being operated; Memory under program and data memory are used for storage system program and data.
