Beneficial effect of the present invention is: the teledata monitor and alarm system based on GPRS that (1) the utility model provides, and can realize the monitoring of system on the computing machine of any connection Internet.This system has used GPRS technology, and GPRS technology adds a set of packet switching system on existing GSM network basis, can be connected, provide data service to user with Internet.GPRS charges by flow, and is specially adapted to that data volume is few, promptness requires in high application.It is high that GPRS communication also has confidentiality, and the features such as reliability is high, and antijamming capability is strong, ensure that the Stability and veracity that data are transmitted.(2) RS485 bus is adopted, because it has good antijamming capability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.Be illustrated in figure 1 a kind of structural representation of the present utility model.Based on a teledata monitoring warning system of GPRS, this system comprises sensor 1 (as the Temperature Humidity Sensor used in warmhouse booth, the pressure transducer used in gas container, the special gas sensor that requires strict occasion to adopt to hazardous gas spillage), GPRS transmission control module 2, server 4 and mobile phone terminal 3; Described sensor is connected with GPRS transmission control module; Described GPRS transmission control module 2 is connected with server 4 and mobile phone terminal 3 communication respectively; Described GPRS transmission control module 2 comprises GPRS transmission unit (SIM900/SIM900A), sim card slot, heating unit, temperature collecting cell, power supply unit and micro-control unit (single-chip microcomputer STM32F103, arm processor S3C6410); Described GPRS transmission unit, sim card slot, heating unit are connected with micro-control unit respectively; Described power supply unit is that GPRS transmission control module 2 is powered, and described temperature collecting cell gathers the temperature of SIM card.Described GPRS transmission control module 2 is connected with adopting 485 buses or 4-20ma current signal between sensor 1.Full duplex communication is adopted between described server 4 and GPRS transmission control module 2.Described server 4 adopts PC.Described heating unit is provided with for fixing and the deck on sim card slot.Described heating unit is SIM heating, and when the data of temperature collecting cell collection are less than the temperature of default, micro-control unit controls heating unit carries out batch (-type) heating, makes temperature remain on the scope of set temperature value about 3 degree.
Micro-control unit carries out digitizing to the data that sensor 1 gathers, and after resolving, information is issued server 4, judge that whether the data gathered are abnormal at server 4, then feedback information is sent it back micro-control unit, feedback information is sent on the mobile phone terminal of related personnel by GPRS transmission unit with note form by micro-control unit, mobile phone terminal comprises SMS, mobile phone A PP client.Mobile phone terminal can show the ambient condition that sensor detects in real time, and when causing danger situation, mobile phone A PP can send the alarm operation prompting related personnel such as vibrations, the tinkle of bells.
Be connected by 485 buses or 4-20ma current signal between sensor 1 with GPRS transmission control module 2.TCP communication is adopted between GPRS transmission control module 2 and server 4.
Sensor 1: the collection being responsible for data, the output signal type of sensor generally has current type and voltage type.Current type represents by the electric current exporting 4-20ma the different numerical value collected.Voltage type adopts RS458 bus mode, adopts RS485 bus to have reasonable antijamming capability.If sensor exports as current signal, then in GPRS transmission control module, need current signal to be converted to voltage signal, voltage signal adopts TCP communication modes to be sent to server after digitizing.If sensor exports as voltage signal, be then directly sent to server by after this voltage digital.
GPRS transmission control module 2:GPRS transmission control module 2 is responsible for process, the transmission work of data.GPRS transmission control module needs analog voltage signal to be converted to digital signal through ADC digital-to-analogue converter.Because of the complicacy of network environment, between GPRS module and server, set up sound data transmission pledge system.(need between GPRS module with server by heartbeat mechanism detect between the two whether link passage unimpeded, after link passage disconnects, GPRS module needs initiatively connection server.Need during data communication to adopt acknowledgement mechanism, not receiving effective response during communication then needs to resend to guarantee that data transmission is normal) environmentally signal quality determine the SIM card that adopts.
Server 4: server 4 is data processings, the core of data operation.Server is held as TCP server, has fixed ip address.Employing full duplex communication between server 4 and GPRS transmission control module 2.Pass through full duplex mode, server 4 receives the data that process GPRS transmission control module 2 sends, data processing complete after server 4 by information feed back to GPRS transmission control module 2, determine whether GPRS transmission control module 2 is necessary feedback information to be sent to mobile phone terminal 3 by feedback information, with the form of short message warning related personnel.
Mobile phone terminal 3: feed back to GPRS transmission control module 2 after the mathematical logic process that server 4 pairs of sensors 1 gather, the feedback information of server 4 is sent on mobile phone terminal 3 by GPRS transmission control module 2 again, warns related personnel in time.This is particularly important to the place that cannot realize 24 hours monitored by personnel, and related personnel receives short message in time and is conducive to taking measures in time to avoid loss.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
