[embodiment]
Based on the Internet of things system of mobile communications network, comprise hand-held mobile terminal, back splint type RFID device, PC server.
A circuit slot is set on the hand-held mobile terminal, binds, provide power supply to this back splint type RFID device simultaneously with back splint type RFID device; The hand-held mobile terminal design has mobile phone terminal inquiring stock system, this system is that a cover is used to instruct the stock inquiry, based on the WindowsMobile system, be used to operate handheld terminal and dorsal clamp type infrared scanner, the bar code information of scanning is sent to the remote service end by the GPRS/3G mobile communications network, by the processing of remote service end, the detailed inventory information of these commodity is turned back to handheld terminal, the personal management stock of assisting management.
Back splint type RFID device is provided with bluetooth equipment, utilize bluetooth serial ports to be synchronized to described hand-held mobile terminal earlier the data that scan, utilize the GPRS/3G mobile communications network of the described hand-held mobile terminal of procedure triggers to connect then, communicate by letter and be positioned at the online background server of INTERNET by SOCKET again and carry out two-way interactive; Dorsal clamp type RFID bar code scanner consists of the following components: light source, receiving system, photoelectric conversion part, decoding circuit, interface circuit, bluetooth module.Groundwork as principle is: the light that is sent by light source passes through irradiation optical system above bar code symbol, the light of returning that is reflected passes through optical system imaging on optical-electrical converter, make it to produce the signal of telecommunication, signal produces an aanalogvoltage after oversampling circuit amplifies, it with shine bar code symbol on the light of returning that is reflected be directly proportional, pass through filtering, shaping again, form with the simulation letter and write corresponding square-wave signal, be interpreted as digital signal through decoder, then digital signal be sent to hand-held mobile terminal by bluetooth.
The PC server is to be positioned at the online PC that has independent static ip address of INTERNET by one to constitute, and can open a plurality of ports and portable terminal simultaneously and communicate, and calls WEBSERVICE and handles a plurality of query requests.
The course of work is: the software that is loaded in portable terminal by triggering, control RFID bar-code reader is discerned the RFID bar code, the data that scan can be sent on the portable terminal by bluetooth serial ports, click inquire button then, can start connection manager and obtain current available GPRS/3G mobile communications network connection, and select the connection approach (acquiescence select INTERNET connect) an of the best automatically, enable this then and connect, after connection starts successfully, utilize socket communication data to be sent on the PC server that is positioned at the INTERNET net.While PC server can call relevant WEBSERVICE data are handled, and feeds back a Query Result to portable terminal.Idiographic flow as shown in Figure 2.
Software section of the present invention is a mobile phone terminal inquiring stock system, below will be from the main flow process of system's operation, the technical indicator of system, system scheme (major technique feature), the system operation process, this software systems are introduced in the aspects such as major function that system realizes.
1, the workflow diagram of this system is as shown in Figure 3:
This system flow main functional modules is as follows:
(1) RFID bar-code identification:
The orthoscopic light that is sent by barcode scanner accords with to bar code through irradiation optical system, the light of returning that is reflected passes through optical system imaging on optical-electrical converter, make it to produce the signal of telecommunication, signal produces an aanalogvoltage after oversampling circuit amplifies, it with shine bar code symbol on the light of returning that is reflected be directly proportional, pass through filtering, shaping again, form and simulate letter and write corresponding square-wave signal, be interpreted as digital signal through decoder, digital signal is stored in a certain port of bluetooth.
(2) serial communication:
Bluetooth is the Radio Transmission Technology of a kind of low cost, high reliability, and bluetooth serial ports communication is the necessary link that realizes RFID identification equipment and handset binding technology.Its main communication process is that application program uses the CreateFile function to open equipment under based on the platform of windowsmobile, current com-state is set, communicate with DeviceIoControl and driver then, with ReadFile read data WriteFile write data.Use the CloseHandle closing device during end of operation.
The configuration of bluetooth serial ports resource parameters is as follows:
System.IO.Port?s.SerialPort?port＝new?System.IO.Port?s.
SerialPort (" COM6 "); The port title of // use appointment
Port.BaudRate=9600; // the serial baud rate is set
Port.Parity=System.IO.Port s.Parity.None; // the parity check agreement is set
Port.StopBit s=8; // standard that each byte is set stops figure place
Port.DataBit s=System.IO.Port s.StopBit s.One; // the normal data bit length of each byte is set.
(3) operator is judged:
The RFID bar-code identification system based on mobile communications network of this patent design can get access to the SIM card information in the mobile communication terminal, obtain the SubscriberNumber and the SerialNumber of this SIM card with plviGeneralInfo, then according to MCC=460; MNC: move=00/02 UNICOM=01 pair of different operators network supporting user and make judgement; The unsupported network user is shielded to native system.
(4) GPRS/3G radio communication:
GPRS is the abbreviation of GPRS (General Packet Radio System), is a kind of technology between the second generation and the third generation, is commonly referred to 2.5G.GPRS adopts the frequency range identical with GSM, frequency bandwidth, burst structure, wireless-modulated standard, frequency hopping rule and identical tdma frame structure.GPRS introduces two new network nodes on based on the GSM network of circuit switching (CSD) mode original: GPRS serving GPRS support node (SGSN) and gateway support node (GGSN).SGSN and MSC be at same hierarchy level, and the memory cell of following the tracks of single MS realizes safety function and access control, and be connected to base station system by frame relay.GGSN supports the intercommunication with external packet-switched networks, and is communicated with via IP-based GPRS backbone network and SGSN.
That the data transfer mode of the present invention's design adopts is SOCKET, after mobile phone is opened GPRS/3G, the socket program can't directly be set up network and connect, so need to obtain current available connection with connection manager earlier, under the WindowsMobile system platform, the present invention obtains current available connection with the EnumNetIdentifier function earlier, in general can obtain following several connected mode:
WAP
Internet is provided with
The setting of acquiescence unit
Safe WAP network
The WAP network
Obtain the connected mode of appointment then by the EstablishConnection function, the fluency of the network of consideration, what this programme adopted is second kind of connected mode, if the connected mode of safe WAP network is adopted in the higher suggestion of the confidentiality of information.When connecting to set up successfully, GPRS/3G then can transmit and receive data to background server by SOCKET communication.
(5) call webservice:
Promptly receive the RFID bar code information that sends from portable terminal, pass to corresponding database interface as parameter by the PC server that is positioned at the INTERNET network.Database can feed back a Query Result to server simultaneously, after the PC server receives the Query Information of database, by the GPRS/3G passage data sync being arrived portable terminal, offers the user and checks.
2, systematic technical indicator:
(1) remote transmission
