Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, this family-school interaction message audiovisual system, mainly comprise: the head of a family holds phone, is used to import specific communication number and the head of a family's tone information; The student holds phone, is used for the incoming traffic number and listens to the head of a family's tone information, and wherein phone can be landline telephone, mobile phone or Personal Handyphone System; The RVR voice system is used to receive the head of a family's tone information and converts the head of a family's tone information to speech data, carries out two-way transfer of data by Internet network and system server; GPRS or cdma wireless digital transmission module are used for the data that wireless receiving RVR voice system server end sends, and are sent to led controller according to communications protocol; The LED display module is connected with GPRS or cdma wireless data transmission equipment, is used to receive the data that GPRS or cdma wireless digital transmission module are sent, and the control LED display shows or the delete message information.The 11st, 12 pin of the TCL232 chip of display panel module; Carry out the data communication of 232 signals with last the 11st, 13 pin of the CPU (W77E58) on GPRS or the cdma wireless digital transmission module; Receive data that RVR voice system server end sends by 232 control sections that are sent to LED LED display module by GPRS or cdma wireless digital transmission module again, message information is presented on the LED display.
The physical circuit principle is as shown in Figure 3: GPRS receives transmitter module and mainly is made up of 6 parts: power control part branch, GPRS unit, data are preserved part, data communication part, man-machine indicating section, CPU temporarily.
1, power control part branch.Power input mainly adopts the 220V alternating current, through the industry control power supply of S-100-12, the alternating current of 220V is directly changed into the direct current of 12V.For wiring board, at first have electrochemical capacitor in the power input part and carry out filtering, carry out overcurrent protection through fuse then, carry out filtering by two filters again, divide two-way supply circuit separately again.One the tunnel gives single-chip microcomputer 8051 (W77E58) power supply after the LM2940 voltage stabilizing becomes DC5V voltage.Another road power supply expands stream output through metal-oxide-semiconductor 2955 again after 34063 step-downs become 5V, by relay control, supply with GPRS (M22) module by after diode 5408,5822 voltage stabilizings at last again.
2, GPRS unit.The M22 module that the GPRS unit is released for BENQ company based on the GPRS technology platform, M22 is GSM/GPRS Class 10 3 frequency modules, and the P3.0 by the RS_RXD on the module, RS_TXD serial communication port and single-chip microcomputer 8051 (W77E58) carries out various data communication to P3.1.
3, data are preserved part temporarily.When the M22 module was sent out data and given 8051,8051 received data directly were kept in the data storage of 8051 inside.And provide 1KB external data memory in 8051.
4, data communication part.The data communication part mainly is meant a data communication between led display unit and 8051.And communication between the two mainly is the communication modes that relies on RS232.In theory, one-side RS232 communication can be transmitted 15 meters.When 8051 handle the data that M22 sends, can after receiving successfully, led display unit return an affirmation value and confirm by issuing the MAX232CSE chip between the serial ports.
5, man-machine indicating section.Man-machine indicating section can be given the people one and judge intuitively.This point can be judged the network state of M22 and the communication situation of data processing centre unit and led display unit by indicator light.Man-machine indication mainly contains two-way, leads up to R7 on the wiring board, and LED1 judges the network condition of M22. Another road is by the R31 on the wiring board, the communication situation of LED3 video data processing center unit and led display unit.
6, CPU.CPU is important to be made up of 8051 (w77E58).It has mainly been born the work of treatment of various data and has solved various communication abnormal conditions timely.Aspect data processing, whether 8051 can inquiry servers initiatively needs the task of handling, if there is task to need to handle, and request server assigns task to be processed to 8051, handles by 8051.If server does not have task, 8051 can inquire with the regular hour again.And 8051 after the task that processing server is assigned, and can open up the buffer memory of very big space as video data in inside, and in the regular hour task, issue led display unit.When handling various communication abnormal conditions, if wireless network signal is when unreliable, 8051 can make the M22 module carry out soft start.Behind the soft start three times or undesired, the supply power voltage of the M22 module of will initiatively breaking (8051 power supply still remains unchanged).Dial by the M22 module again, check whether dialing is successful.These all work all are to have guaranteed just to allow to carry out transfer of data under the reliable situation of communication, have so just guaranteed reliability of data transmission.
Led display unit mainly is made up of 3 parts: power control part branch, data are preserved part, CPU temporarily.
1, power control part branch.Power input mainly adopts the 220V alternating current, through the industry control power supply, the alternating current of 220V is directly changed into the direct current of 5V, directly supplies with led display unit again and uses.
2, data are preserved part temporarily.When 8051 data were given led display unit, led display unit was directly preserved received data the inside of led display unit.
3, CPU.The central processing unit of led display unit is also formed by 8051, and is the core that shows, part.It mainly is that function is to have born communication part and the data that receive are carried out Presentation Function.After 8051 of LED display part is received data and handled, carry out 138 decodings by 74ALS138, and the data of decoding gained are carried out the sheet choosing to the display part.8051 of the LED display part again by data/address bus then, carries out data-driven by 74ALS245, display message information is come out again.
As shown in Figure 2, be application flow of the present utility model, the head of a family enters the RVR voice platform by phone and leaves a message, and server end is connected the processing of carrying out data with leaving message prompt information with wireless communication connected mode with LED display; The student enters the RVR voice platform by phone again by the information on the LED display of checking and listens to message.School also can be with the relevant information of Web mode by LED display issue campus.
