Embodiment

In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.

As shown in the figure, the multi-functional automatic station name announcing system of a kind of bus based on GPS, comprise, single-chip microcomputer, GPS receiver module, GPRS transceiver module, voice broadcast module, described GPS receiver module, GPRS transceiver module are connected to single-chip microcomputer, single-chip microcomputer is also provided with voice broadcast module, display module, input media, and described single-chip microcomputer, voice broadcast module, display module, input media are connected with power module, and power module is connected to GPS receiver module, GPRS transceiver module.

Described single-chip microcomputer mainly realize information processing, control and with the functions such as dispatch terminal communication.Receive the data message of GPS, the position data according to GPS carries out automatic broadcasting control, loses in short-term, then carry out position prediction if there is gps signal.If the velocity information receiving GPS is greater than the upper limit threshold of setting, then drive voice broadcast module to report to the police, remind driver's hypervelocity, be uploaded to scheduling controlling terminal simultaneously by GPRS, terminal display screen directly can show the relevant information of over-speed vehicles.In addition, the information data that GPS receives by main control module is uploaded to scheduling controlling terminal in real time by GPRS, realizes monitoring in real time etc.Meanwhile, also by the order of GPRS receiving scheduling terminal, realize two-way intercommunication scheduling and monitoring.

Described GPS receiver module adopts GPS-9543LP locating module, and its positioning precision is 10m.Bring into operation after powering up, its basic operational process has: self-inspection, initialization, navigation, satellite data collection etc.Satellite situation and date, time, latitude, longitude, speed, highly, the information such as course all adopts ASCII character to export, GPS passes through satellite received signal, and the signal through single-chip microcomputer process is shown by corresponding device, play the effect of Geographic mapping.

Operating voltage due to the input/output end port of single-chip microcomputer STC12C5A60S2 is+3.3V, and the operating voltage of GPS is+5.0V, therefore in order to protect single-chip microcomputer not to be burned protective resistance that we are connected in series 27K between which.Operating voltage in view of GPS is+5.0V, and what therefore module 1,2,3 pin connect is all+5V power supply.Due to this module power on after can automatic reception and send locator data, namely GPS module does not need the steering order that receiving system sends, and does not need initialization yet, does not therefore need the control operation of single-chip microcomputer.

Described voice broadcast module adopts ISD1700 chip to have speech recording and reproducing function, can be controlled ISD1700 by single-chip microcomputer SPI serial ports, the suggestion voice previously recorded, after processing through note amplifier, loudspeaker will be eventually passed and reports out.When system cannot realize automatic broadcasting, manually can report under the effect of key system.The duty of chip is judged by the light on and off of the LED at/LED pipe pin place.

ISD1700 series recording and playback ic is all reasonable a kind of high performance chips of integrated level, performance, also has new record recording prompt function.This recording chip service area is (2.4V-5.5V), and employing rate is (4K-12K), can also subsection record.Because this chip internal has oscillator, so we can connect outer meeting resistance to regulate its concussion frequency in its outside.

Described display module adopts liquid crystal display LCD, has power low, does not have electromagnetic radiation, and interface is simple, and effective area is large, and applied range, not only can show numeral, character, and can show word and figure.Also there is antijamming capability simultaneously strong, the advantages such as volume is little, cheap.

Because graphic LCD module M12864 module has Display of Chinese characters, figure and character, the ability of display of skipping, function ratio is more complete, and reality contains much information, and therefore I selects this module in this design.This module column driver is use two KS0108B effects, uses a KS0107B as line driver.The P0 mouth of single-chip microcomputer connects with data input pin DB0 ~ DB7, CS1 and CS2 end is chip selection signal, and FL-E is liquid crystal display switch control rule mouth, has added resistance in order to prevent burning single-chip microcomputer during hot plug in port.As long as provide power supply just can produce horizontal-drive signal and various synchronizing signal.

Described power module is the direct voltage output of+5V, consists of connection LM2576S chip, two electric capacity, an inductance and voltage stabilizing diodes.It can carry out voltage transitions, the DC voltage on bus is converted to+5.0V by+24.0V, and too generates heat for chip, and the problem burnt out may be caused to be do not need to consider.Step-down switching type voltage stabilizing integrated chip LM2576S is the output current produced by NS is 3A, and it has perfect protection circuit and fixed oscillator and benchmark voltage stabilizer are contained in inside, and it also has the function of Limited Current and Thermal shutdown circuit simultaneously.

More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
