Abstract

The utility model relates to a bus enquiry system which solves the problem that a passenger can not choose the optimum bus when waiting for a bus on a bus stop. The enquiry system comprises a GPS vehicle-borne terminal (1) installed on the bus and used for receiving a GPS satellite signal and sending the position information of the bus; a bus monitoring center (2) connected with the vehicle-borne terminal (1) through the mobile communication network and used for receiving and forwarding the position information of the bus; and an electronic stop board (3) connected with the bus monitoring center through communication and used for displaying the latest position information of the bus.

Description

A kind of bus inquiry system

Technical field

The utility model relates to a kind of bus inquiry system, more particularly, relates to a kind of bus real time inquiry system based on the GPS technology.

Background technology

At present along with the increasing rapidly of urban population, the bus career development is rapid, and circuit and bus quantity also rapidly increase.In peak period on and off duty, the bus-stop often queues motorcade.On the other hand, the behind of economic rapid growth, the raising of production efficiency has brought the maxim that time is life.Therefore for the city working clan, platform how to select that this demand of arrival destination that a bus can be the fastest becomes more and more urgent.

GPS technology: GPS is a GPS, lasts 24 years by the U.S. and succeeds in developing, and has at aeroamphibious to realize three-dimensional localization and navigation function.It not only has navigation locating function, also have range finding, when surveying, function such as test the speed.Progressively civil nature along with this technology extensively is applied at vehicle electric field, makes it have many additional functions such as security protection, scheduling, detection.Nowadays gps system is progressively at city bus.

The utility model content

The technical problems to be solved in the utility model is that the defective at the above-mentioned motroist of prior art can not select best bus when platform is waited for bus provides a kind of bus inquiry system.

The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of bus inquiry system, it is characterized in that, comprising: be installed on the bus GPS car-mounted terminal that is used to receive gps satellite signal and sends bus positional information; Be connected with the GPS car-mounted terminal by mobile communications network, be used to receive and transmit the bus Surveillance center of bus positional information; Surveillance center communicates to connect with bus, is used to show the electronic stop plate of up-to-date bus positional information.

In bus inquiry system described in the utility model, described GPS car-mounted terminal comprises microprocessor and the vehicle-mounted receiver of the GPS that is connected with microprocessor, site information memory module, site information update module and mobile communication module.

In bus inquiry system described in the utility model, described mobile communication module comprises gsm module, GPRS module or CDMA module, is used for sending SMS message to mobile communications network.

Implement bus inquiry system of the present utility model, have following beneficial effect:

Bus is every during through a website, the GPS car-mounted terminal sends to bus Surveillance center with the information of arriving at a station, bus Surveillance center delivers to electronic stop plate with relevant information then, and the motroist who makes at platform can select best bus, thereby has reduced Waiting time.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the system schematic of the utility model bus inquiry system;

Fig. 2 is the module map of the GPS car-mounted terminal of the utility model bus inquiry system.

Embodiment

In buses such as platform, people often do not know that public transport arrives the information of each website, to such an extent as to wasted a large amount of time at website.The utility model provides a kind of bus real time inquiry system based on the GPS technology, and the convenient motroist who waits for bus at platform selects best bus, thereby has reduced the time of waiting for bus at platform.

As shown in Figure 1, bus inquiry system of the present utility model comprises GPS car-mounted terminal 1, bus Surveillance center 2 and electronic stop plate 3.GPS car-mounted terminal 1 is installed on the bus, be used to receive gps satellite signal and send relevant information, stored this circuit the website latitude and longitude information of process.Bus Surveillance center 2 is connected to GPS car-mounted terminal 1 by mobile communications network, is used for receiving and transmitting various information, and in real time bus is monitored.Electronic stop plate 3 communicates to connect with bus Surveillance center, is used to show up-to-date bus positional information.

GPS car-mounted terminal 1 on the bus has been stored each site information.Bus is every during through a website, and the vehicle-mounted receiver 4 of GPS with the latitude and longitude information that receives and canned data relatively if they are consistent, then initiatively reports bus Surveillance center 2 with the information of arriving at a station by mobile communication module 7.Bus Surveillance center 2 is published to these information each electronic stop plate 3 that this bus will pass through automatically.Electronic stop plate 3 shows from each nearest circuit bus information of this website (being that bus has arrived that station) then.Citizen just can take according to the bus of choice of location the best of this car like this, thereby have farthest made things convenient for the passenger, for the passenger has saved the time.

As shown in Figure 2, there is shown the structure of the utility model GPS car-mounted terminal 1.Except common microprocessor 8 (CPU), FLASH storer, I/O control, micro harddisk, SD interface, USB interface, display screen/touch-screen, wireless anti-theft module, the GPS vehicle mobile terminals 1 that the utility model provides also comprises the vehicle-mounted receiver 4 of GPS, site information memory module 5, site information update module 6 and mobile communication module 7.The vehicle-mounted receiver 4 of GPS is used to receive the gps signal that gps satellite sends, and generates current location information.Site information memory module 5 is used for the storage site latitude and longitude information.Site information update module 6 is used to receive the lastest imformation that public transport Surveillance center 2 sends, and site information is upgraded.CPU 8 sends vehicle and sails status information into according to current location information and charging section information when entering the bus station, send vehicle and sail out of status information when sailing out of website.Mobile communication module 7 can be but be not limited to GSM, GPRS or cdma wireless module, is used for sending the short message that comprises car status information to mobile communications network.

Except that above-mentioned functions, bus inquiry system of the present utility model can also report alert, issue meteorology and public information, scheduling, navigate, provides failed services and medical services.
