Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1, a kind of wireless display screen control system based on GSM and ZigBee technology, comprise mobile phone transmitting terminal 1, TC35 module 4, microprocessor 5 and Zigbee gateway module 7, described mobile phone transmitting terminal 1 is connected with TC35 module 4 by GSM network 2, described TC35 module 4 is joined with SIM card 3, microprocessor 5, described microprocessor 5 is connected with power module 6, Zigbee gateway module 7, described Zigbee gateway module 7 and multiple Zigbee node module 8 wireless connections, described multiple Zigbee node modules 8 connect corresponding to multiple display screens 9.
As shown in Figure 2, described power module 6 adopts solar panel 10 to charge; Described display screen 9 outsides are coated with transparent anticorrosive film 11; Described anticorrosive film is anodic oxidation titanic oxide material.
As shown in Figure 3, described microprocessor 5 is S3C2440ARM chip, its peripheral SDRAM, NANDFLASH storer of connecting, for depositing the 128B data that will show corresponding with display screen and the information reading from gsm module, microprocessor 5, by reading the data of TC35 module 4 with the carrying of short message form, is shown to it in LED display after treatment.Because the Chinese character in short message is only 1 coding, coding is become Chinese character dot matrix data by microprocessor 5 application systems, must configuration Hanzi font library.Therefore, when design scm application system, control center edits PDU packet data, adopts self-defining data mode.Wherein, represent that the data of Chinese character directly use the internal code of Chinese character, the character library of system configuration is the Chinese character base of GB-2312 coding, i.e. region-position code Chinese character base.The H57V2562GTR that SDRAM adopts, has the storage space of 32MB, and NANDFLASH adopts the K9F2G08ROA of Samsung.
As shown in Figure 4, TC35 can fast and safely realize data, voice transfer, Short Message Service and the fax in system schema reliably.The operating voltage of module is 3.3V～5.5V, can be operated in 900MHz～1800MHz.Module has AT Command Set interface, supports the short message of text and PDU pattern.Realize the transmitted in both directions of power supply connection, instruction, data, voice signal and control signal by the ZIF connector of 40 pins.Antenna connector by ZIF connector and 50 Ω can connect respectively SIM card support and antenna.
As shown in Figure 3 and Figure 5, described Zigbee gateway module 7 and Zigbee node module 8 are selected CC2530 module.CC2530 is a real SOC (system on a chip) (SoC) solution for 2.4-GHz IEEE802.15.4, ZigBee and RF4CE application.It can set up powerful network node with low-down total material cost.Use ZigBee wireless transport module to realize wireless data demonstration information and transmit and upgrade, avoided using the data transmission of the GSM/GPRS communication network based on operator of China Mobile and bring the overhead costs in the time of information updating.
As shown in Figure 6, described display screen 9 is LED, and the area of LED display board is very large, and its front is formed by the cascade of LED displaying block, and the back side is driving circuit.Because the drive current of LED is relatively large, driving circuit should be tried one's best close with LED lattice module.Therefore Drive of row and column device is generally all arranged on the back side of screen body.In the driving circuit of LED display board, having adopted 74HC595 chip, is the cmos device of silicon structure, and compatible low-voltage TTL circuit has displacement, parallel latch and ternary output function that 8 bit strings enter and go out.Shift register and latch use independently clock, and data DATA, at the rising edge input shift register of CLK, goes in the latch entering at the rising edge of SLR.In the time that enable signal OE is low level, the data of latch output to LED.74HC595 chip can solve data and show and data serial transmission collision problem in time, in showing the each column data of 1 row, can prepare down the LED data of 1 row.Taking 1/16 line scanning as example.Each pulse will cause that 1 bit data moves in 74HC595, and after the data of 1 row have all been moved, latch signal control data move into latch from the register of 74HC595.A, B, C, D are line scan signals, and wherein A is lowest order, by the line scanning of 4/16 code translator control LED screen.OE is the shadow signal that disappears, and it can select to control row signal or column signal, whether can be lit and control the brightness of whole screen for LED dot matrix.If OE controls column signal, it connects the OE end of 74HC595 chip, because only have the output of 74HC595 in the time that OE is low level just effective, otherwise output tri-state.If OE controls row signal, it receives the Enable Pin of 4/16 code translator, and when low level, line scanning is inoperative.
When actual use, mobile phone transmitting terminal 1 sends control information and the content-data that will show, by GSM network 2, data message is dealt into TC35 module 4, SIM card 3 real-time storage relevant informations simultaneously, microprocessor 5 is passed to Zigbee gateway module 7 after receiving TC35 module 4 information after treatment, Zigbee gateway module 7 is again by the wireless multiple Zigbee node modules 8 that information data sent to each corner of the unit of being distributed in of respective communication agreement, Zigbee node module 8 is controlled display screen 9 information is shown, display screen 9 adopts solar panel to power to it, and in display screen 9 surface coverage transparent anticorrosive, reduce the destruction of extraneous inclement weather to display screen.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification of above embodiment being done according to the utility model technical spirit, change and equivalent structure change, and all still belong in the protection domain of technical solutions of the utility model.
