Description

A kind of portable guide's instrument

Technical field

The utility model relates to a kind of portable guide's instrument.

Background technology

Along with the raising of expanding economy and people's living standard, tourism has become the requisite ingredient of life.But when going on a tour, face again, can't carefully have a taste of historical allusion, the sight spot intension of scenic spot because the visitor of tourist attractions is too much.The explanation at scenic spot substantially all is to be explained by the guide at present, but this is a kind of explanation mode of passive type, self diathesis and time and tourist arrivals's the restriction owing to be subjected to conducting a sightseeing tour, the visitor time has a glance at often in visit, historical allusion, legend and humane inside information that can't the detail knowledge sight spot; Even guide interpreting is very excellent, but because the visitor is numerous, a plurality of guide interpretings interfere with each other, and do not reach the effect of explanation.Therefore, though make people feel to travel, do not reach the purpose of tourism fully to the scenic spot; For the scenic spot, do not reach good the effect of publicity yet.

Summary of the invention

The purpose of this utility model is to provide a kind of portable guide's instrument, according to visitor's tourism route,, carry out the explanation such as historical allusion, landscape at sight spot for the visitor for the visitor provides carry-on tour guide device, reaching better is that the visitor serves, and strengthens the purpose to the understanding at sight spot.

The technical scheme that its technical matters that solves the utility model adopts is: comprise antenna, GPS module, CPU single-chip microcomputer, RS232 serial ports, signal lamp, speech memory.The CPU single-chip microcomputer is connected with speech memory with GPS module, RS232 serial ports, signal lamp respectively, and antenna is connected with the GPS module.

Described CPU single-chip microcomputer adopts 51 series A T89c51SND single-chip microcomputers, is connected with the GPS module by the RS232 serial ports, is connected with speech memory with signal lamp by the I/O mouth.

The module of described GPS modular belt built-in aerial.

Described speech memory adopts K9K1G08UOM type or SD secure digital storage card.

The useful effect that the utlity model has is: the traveller can under the help of GPS location, listen to this sight spot and introduce at any time according to the travelling route of oneself at arbitrary sight spot.Adopt the GPS module to conduct a sightseeing tour, have the precision height, time and people's influence.Therefore, this product has very big using value.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, the utility model comprises: comprise antenna 1, GPS module 2, CPU single-chip microcomputer 3, RS232 communication port 4, signal lamp 5, speech memory 6.CPU single-chip microcomputer 3 is connected with GPS module 2, RS232 communication port 4, signal lamp 5 and speech memory 6 respectively, and antenna 1 is connected with GPS module 2.

As described in Fig. 2 to Fig. 5,3 employings of CPU single-chip microcomputer as 51 series monolithic AT89c51SND etc. are connected with the GPS module by 232 serial ports, are connected with speech memory with signal lamp by the I/O mouth.The module of described GPS module 2 band built-in aerials.Described speech memory 6 adopts as audio record circuits such as K9K1G08UOM type or SD (safe digital card) storage cards.

3 employings of CPU single-chip microcomputer as 51 series monolithic AT89c51SND etc., the RAM of its built-in 512 bytes, the Flash EPROM of 64K byte, 8 I/O mouths, 3 16 bit timing counters, 6 interrupt sources, a full duplex serial ports, 8 vectorial secondary interrupt structures also have the side program memory lock function of encrypted array simultaneously.Timer and relevant P port lines have been used in the design.Timer is mainly used in and forms a second level signal, for measurement provides time conditions.The work that single-chip microcomputer is mainly finished is by serial ports input gps data, after the processing result is issued in the mode of voice and signal lamp, adopts the RS232 mode to communicate by letter with host computer simultaneously.

General GPS module 2 occupies critical positions in this device, because speed and position signalling are gathered by it, here select the module of the reasonable band built-in aerial of performance for use, by reading the position signalling that serial ports provides, reach the purpose of position sampling, the output data form is the NMEA183 sign indicating number.

Speech memory 6 adopts the K9K1G08UOM audio record circuit, and sheet is interior by required whole basic function circuit of high-quality speech recording and reproducing system such as clock oscillator, 128K byte E2PROM (but electrically programmable erasable read only memory), microphony amplifier, automatic gain control circuit, anti-interference filter, differential power amplifiers.The recording-reproducing system of a minimum only is made up of an Electret condenser microphone, loudspeaker, two buttons, power supply and a spot of resistance, electric capacity.During practical application, the person for recording can be provided with corresponding A0～A7 combination voluntarily according to the zero-time of every section voice.This memory span is 32Gbit, satisfies the needs of this device fully.

Software adopts the circulation read mode to carry out, and native system software adopts modular design method.

Total system is made up of system initialization module, gps data sampling module, judgement sight spot sign judge module, speech processing module.After powering on, at first enter system initialization module, after this system software will bring into operation, and reflect system running state in real time.

Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
