Abstract
The utility model relates to the field of automobile instruments and electronic instruments and particularly relates to a direction display device for displaying driving directions and routes of a taxi. The direction display device comprises a main control module, an LED display, an LED driving module, an LCD (liquid crystal display) and an input module, wherein the main control module is connected with the LCD, the LED driving module is connected with the main control module and the LED display, and the input module is connected with the main control module. The direction display device is capable of providing taxi operation states such as vacancy, sharing, fullness and the like and displaying the directions of taxi sharing, so that passengers can select riding conveniently, and a good solution is provided for taxi sharing operation.
Description
Technical field
The utility model relates to auto meter, electronic machine field, shows to hire out vehicle traveling direction, route, is specially the direction read out instrument.
Background technology
Along with city's development, the traffic problems in the city have become the great difficult problem that each big city faces.As the part of public transport, existing taxicar only provides the one way service, exists the waste of resource to a certain extent; Improve the degree of utilization of taxicar for actv.; Alleviate incommutation pressure, many areas begin to carry out share-car, and existing taximeter can only provide one way to charge; Can't travel way be shown to the passenger, be not easy to the passenger and select share-car.
Summary of the invention
The utility model provides a kind of direction read out instrument to the problems referred to above, has solved problems such as many people share-car charging, the demonstration of taxicar motoring condition, running route demonstration.
The concrete technical scheme of the utility model is following: the direction read out instrument; Form by main control module, light-emitting diode display, LED driver module, LCD display, load module; Main control module is connected with LCD display; The LED driver module connects main control module and light-emitting diode display, and load module is connected with main control module.
Main control module receives the input data of load module, shows through handling back transmission display data driving LCD display, sends data to the LED driver module simultaneously, is shown by LED driver module driving LED telltale.
Before light-emitting diode display is installed in car bumper wind glass; To the outer demonstration information of car; Wait passenger by bus in the roadside and obtain information such as going of current operation state of taxicar and vehicle and share-car direction through this light-emitting diode display; LCD display and load module are the internal piloting platform, user in the car is shown and input control is provided, to current operation state of taxicar and vehicle go and information such as share-car direction is made amendment.
The utlity model has following function:
1, provides the demonstration of hire a car operation state such as empty wagons, share-car, full etc. and share-car direction, make things convenient for the passenger to select by bus, the good solution of share-car operation is provided, solved in the taxi sharing operation and the information communication problem between the passenger.
2, the control platform of LCD display and load module composition provides the interactive environment of hommization, has made things convenient for the control of user to the taxicar driving information that light-emitting diode display showed.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1---main control module, 2---light-emitting diode display, 3---LED driver module, 4---LCD display, 5---load module.
The specific embodiment
Below in conjunction with specific embodiment and Figure of description the utility model is described further.Specific embodiment described herein is only in order to explaining the utility model, and is not used in qualification the utility model.
Specific embodiment:
The direction read out instrument is made up of main control module, light-emitting diode display, LED driver module, LCD display and load module, and main control module is connected with LCD display, and the LED driver module connects main control module and light-emitting diode display, and load module is connected with main control module.
Main control module uses the mega series monolithic; Can satisfy the various port of native system needs; Receive the input data of load module; Show through handling back transmission display data driving LCD display, send data to the LED driver module simultaneously, show by LED driver module driving LED telltale.
Before light-emitting diode display is installed in car bumper wind glass,, waits passenger by bus in the roadside and obtain information such as going of current operation state of taxicar and vehicle and share-car direction through this light-emitting diode display the outer demonstration information of car.Light-emitting diode display is the some matrix LED of 64*16, and whole lattice energy shows character and the Chinese character of 4 16*16, and whole display module is a minimum unit with the dot matrix of 8*8, shows with realization through LED driver module control ranks signal.Column signal shows employing 74HC595 chip in the LED driver module, because columns is 64, adopts the mode of 74HC595 cascade; Form 64 serial data chain; Each control one row LED because the line number of light-emitting diode display is 16, has adopted 2 74HC138 control row signals.
LCD display and load module are the internal piloting platform, user in the car is shown and input control is provided, to current operation state of taxicar and vehicle go and information such as share-car direction is made amendment.What LCD display adopted is the screen of NOKIA5110 mobile phone; Adopt serial ports to control; Main control module carries out the control of display data through the communication of IO mouth simulative serial port to LCD display, and what load module adopted is the numeric keypad of PS/2, adopts serial ports to be connected with main control module.
The direction read out instrument that the utility model relates to; Provide the demonstration of hire a car operation state such as empty wagons, share-car, full etc. and share-car direction, make things convenient for the passenger to select by bus; The good solution of share-car operation is provided, has solved in the taxi sharing operation and the information communication problem between the passenger; The control platform that LCD display and load module are formed provides the interactive environment of hommization, has made things convenient for the control of user to the taxicar driving information that light-emitting diode display showed.
Claims (2)
