Fig. 1 is the structure chart of diagram whole system of the present invention.Whole system comprises two parts: hand-set host end and LED display client are designated hereinafter simply as mobile phone terminal and display end.Mobile phone terminal is mainly finished following functions: pattern generation or character, and reading displayed end state is also controlled; The display end major function is display pattern, gathers self (perhaps environment) state and feeds back to mobile phone terminal.
Below introduce in detail scheme and the design at two ends:
LED display end system
The LED display end needs following components to realize according to requirement of system design: control section, wireless transmission, display part, power unit, state acquisition part.
Control MCU
Because the function that need to finish is few, and less demanding for autgmentability, and for stability, low-power consumption is had relatively high expectations, so control section the present invention does not adopt popular arm controller, but adopt 8 ATmega644PA system single-chip microcomputers of AVR company.Its major advantage is as follows:
System's dominant frequency is up to 20MHz, and instruction execution speed can reach 20MIPS;
There is multiple low power pattern to switch;
Integrated 8 path 10bit ADC, integrated two-way UART, TWI, the multiple peripheral hardware such as SPI
The DRQFN encapsulation can fully reduce the space;
These characteristics have all fully satisfied the requirement of whole system.
Wireless transport module
What wireless transport module used is the HC-06 bluetooth module of wavesen company, and its key property comprises
Support bluetooth 2.0 versions
Meet mark HCl port (UART)
Low-cost
This bluetooth module uses UART to be connected with system, supports baud rate up to 115200bps, and it is connected as shown in Figure 2 with control system.
BT_RXD/BT_TXD is bluetooth and system communication serial ports, and BT_nRST is the bluetooth module reseting port, and BT_Status is the indication of bluetooth module state, when it is in the pairing state, is output as the square wave of 50ms; When it is in connection status, be output as lasting high level.
It is before the connection of Bluetooth of mobile phone module is finished, and itself and single-chip microcomputer interactive interface are the AT pattern; And when its with Bluetooth pairing and after being connected, its function just is equivalent to transparent serial ports, can carry out data communication with mobile phone terminal until link disconnection.When bluetooth module was in standby mode, the mobile phone that had matched can be directly sends picture to bluetooth module, and unpaired mobile phone need match first, inputted correct PIN code (namely match password) and can match.The appearance factory PIN code of this bluetooth module is " 1234 ", and its PIN code can be made amendment by sending the AT instruction to bluetooth module.
Display module
Traditional dot matrix display, employing be the rank scanning mode.In the situation that screen is smaller, can adopt the driving chips such as 74HC595 to finish control; But when the ranks number was many, for example 16x32 may need nearly tens to 20 driving control chips.This will produce several problems, and cabling can more complicated cause circuit reliability not high, and chip and cost of manufacture can uprise, and have increased the weight of the burden of singlechip control chip, and are unfavorable for the design of miniaturization and portability.In order to overcome above shortcoming, what the present invention selected is the AS1130LED dot matrix driving chip of Austrian Microtronic A/S (AMS).The Cross-Plexing mode that it adopts on type of drive can reduce the number of control line widely.Its basic principle is exactly on a line forward and oppositely and connect two LED lamps, and when the output forward voltage, the LED lamp of forward is bright, and when the output reverse voltage, reverse LED lamp is bright.The dot matrix of such 11x12 only needs 12 control lines and 1 control chip.And it can move to left in the situation that do not take the mcu time and finish such as flicker, and the function such as move to right.
The present invention uses two AS1130 to form the 11x24 LED dot matrix demonstration of totally 264 points.Itself and MCU johning knot composition are as shown in Figure 3.The drive current of each LEDs can arrange separately, and being divided into from 0-30mA is 256 grades (8bit), this so that.Single-chip microcomputer by the I2C interface with communicate.
Power-supply system
Whole system has 264 LEDs, but the lamp that moment lights simultaneously only has 22, and every LED lamp maximum drive current is 30mA, so its maximum current is about 660mA.Following table has been listed the general power consumption of modules:
System's power consumption is estimated
| Sequence number | Module | Power consumption (VDD=3.3V) |
| 1 | ATmega64 | 20mA |
[0042]?
| 2 | Bluetooth module | 50mA is in the |
| 3 | AS1130 | 340mA×2＝ |
| 4 | EEPROM | 2mA |
| ? | Amount to: | 700mA |
According to above estimation, the present invention only needs the Buck type DC to DC converter about 1A just can meet the demands.That the present invention selects is the AAT1145 of Analogic Tech company, and maximum output current is that outside of 1.5A needs a 22uFMLCC electric capacity.
During the design switch converters, because the current ratio of whole system is larger, this is just so that the electric current that power supply ground (PGND) refluxes is very large.Therefore need to separate power supply ground (PGND) and simulation ground (AGND), then at system power supply input one point earth.
The power supply topological structure of system as shown in Figure 4.BT3V3 is the power supply for the HC-06 module for power supply, because bluetooth module when making amendment Password Operations, needs complete power down, to reach the purpose that empties memory internal.
Other hardware devices
External memory storage
Although ATmega644PA is the integrated inner EEPROM of 2Kbit, in order to improve character library and picture-storage capacity and follow-up code upgrade requirement, the present invention has still added the EEPROM of 64Kbit in the outside.That the present invention selects is the CAT24C64 of ON Semiconductor company, as shown in Figure 5.It uses the I2C interface to be connected with single-chip microcomputer, and maximum clock speed reaches 1MHz, and its chips A0, A2, A3 pin are I2C address choice pin.
Temperature and battery electric quantity collection
In order to detect ambient temperature, the present invention has added thermistor and has used MCU to carry ADC and carry out temperature acquisition; In order to guarantee that cell voltage can work and calculate dump energy, mcu uses bleeder circuit to detect cell voltage simultaneously.
The GPS module
The longitude and latitude that the GPS module directly needs by serial ports output.Baud rate is 9600bps.

Communicate by letter with mobile phone terminal
LED shows control
External status monitoring and control
The system initialization content of ATMega644PA mainly comprises: 1) system clock initialization, select the outer 16MHz clock of sheet; 2) external pin configuration: configuration PD2～PD3 is that UART interface and bluetooth module communicate, and PC0～PC1 is that the I2C interface is communicated by letter with AS1130; The related register initialization such as 3) interruption, timer/counter and FLASH.4) bluetooth module initialization is placed into the wait connection status to bluetooth module.
Fig. 6 shows software flow.System is with the data that initiatively read in the inner specified address area of EEPROM after the initialization, and data are copied in the 4k internal memory, then these data are written among the AS1130, and then AS1130 gives dot array data the LED dot matrix screen and controls dot matrix screen data are shown.
Under common operating state, bluetooth module is in the pairing wait state.When Bluetooth of mobile phone initiatively matched, mobile phone just can successfully match after only having the correct PIN code of input.After the successful matching, mobile phone uses software to send image data to bluetooth, and bluetooth module writes the EEPROM correspondence position with receive data and by the I2C interface.MCU can cross AS1130 to the renewal data communication device that obtains and is shown on the LED dot matrix screen afterwards.
Because system not only needs to finish the function that shows the single width picture, and to finish and for example increase picture, the deletion picture, up/down is turned over picture, mobile picture, the functions such as flickering display, this just need to add the number order bag can realize above function in communication process.
When the data that send when mobile phone terminal are not the picture bag, the single-chip microcomputer receive data, be flag bit " 0x05 " if recognize the start bit of valid data, what this data packet transmission will be thought by system so is control command, namely controls brightness, speed, moving direction that LED shows.The form of control command can independently define.For example " 0x05 0x10 0x08 0x01 ", the meaning of representative is: " 0x05 " is the control flag bit, " 0x10 " control brightness (the brightness controlled range is 0x00-0xFF, and the 0x00 representative is extinguished, and the 0xFF representative is the brightest, and the larger brightness of numerical value is higher); " 0x08 " is used for controlling flash speed (control range 0x00-0x09, it is slower that numeral is flashed more greatly speed); " 0x01 " is direction control bit (0x01 is moving direction to moving to left, and the 0x02 representative moves right, and the 0x00 representative stops).If the start bit of valid data is not " 0x05 ", will give tacit consent to so this secondary data is that LED shows the new picture that will show, system will deposit data in the eeprom address scope of appointment in order.
On this external communication protocol, display end is supported mobile phone terminal inquiry current state, current which width of cloth that is shown as for example, Current Temperatures, current battery electric quantity and current location etc.
Owing to the transmission unsteadiness of bluetooth, whole system is not unidirectional transmission system, needs display end to feed back the contents such as state information in addition.This just needs the present invention to need to add more bag to guarantee stable transmission in transmission course.
