By the direction indicator for the car sharing of the taxi, which is disclosed by the utility model, the operating efficiency and the income of the taxi can be enhanced, more passengers can also be served in time, and the traffic jam of a city and the carbon emission of the running of a vehicle are reduced.
Description
Technical field
The utility model relates to technical field of automotive electronics, in particular, relates to a kind of taxi sharing trafficator.
Background technology
Blocking up of present urban transportation is more and more serious, causes huge difficulty for the public's trip.A kind of important selection that conveniently becomes public's trip of taxi, people are also increasing the demand of taxi.Yet a phenomenon that can not be ignored is: people cause the quantity of taxi to increase to the demand growth of taxi, and the quantity increase of taxi causes traffic to be blocked up more, the blocking up and increase the demand of people conversely of traffic to taxi ...So vicious cycle becomes the one of the main reasons of blocking up and can't bear that causes urban transportation nowadays.
Summary of the invention
Problem to be solved in the utility model provides a kind of taxi sharing trafficator for improving the problems referred to above exactly.
The technical scheme that the utility model adopted is:
A kind of taxi sharing trafficator comprises the large LED array indicator and the controller that are connected in the serial communication mode, it is characterized in that: described large LED array indicator is arranged on the top of taxi, and described controller is arranged in the car; Described large LED array indicator comprises: with the CPU that the car internal controller is connected by serial communication, CPU is connected to decoding scheme, and decoding scheme connects driving circuit again, and driving circuit connects the LED array of display; Described LED array of display comprises M * N highlighted led array and 3 highlighted LED; The formation of described car internal controller comprises: as the CPU of control core, the keyboard that is used to import links to each other with CPU, and CPU is connected with display.
Described large LED array indicator is made of highlighted led array, and M * N highlighted LED is in order to show 2～4 Chinese characters.Wherein M and N are respectively 8 integral multiple.
Described highlighted LED is set to 3.
The beneficial effects of the utility model are: not only can improve the efficiency of operation and the income of taxi, also can make more passenger be served, reduce urban traffic blocking and vehicle operating carbon emission timely.

Embodiment
Below in conjunction with embodiment and accompanying drawing a kind of taxi sharing trafficator of the present utility model is made a detailed description.
As shown in Figure 1, taxi sharing trafficator of the present utility model is made of two parts: be installed on roof large LED array indicator and and be installed in controller in the car, be connected by serial communication between them.This is provided with and the travel direction of taxi can be presented on the described large LED array indicator by the controller that is arranged in the car with the quantity that can increase the passenger.
Show the system architecture diagram of the large LED array indicator that is installed on roof as Fig. 2, as seen from the figure, described large LED array indicator comprises: the CPU that is connected by serial communication with the car internal controller, CPU is connected to decoding scheme, decoding scheme connects driving circuit again, and driving circuit connects the LED array of display.CPU receives the information that needs demonstration by serial communication from the car internal controller, then successively by decoding scheme and driving circuit driving LED array, demonstrates travel direction of hiring a car and the number that can increase the passenger.
When taxi does not have full and obtaining under the situation of passenger permission, the driver can be presented at the travel direction of taxi and the quantity that can increase the passenger again on the large LED array indicator by the controller in the car.The driver imports the travel direction of taxi for convenience, and the controller input digit in car is determined the travel direction of large LED array indicator for displaying taxi and can be increased passenger's quantity again.
Large LED array indicator adopts M * N highlighted LED to form, and wherein M and N are respectively 8 integral multiple, in order to show 2～4 Chinese characters.
3 highlighted LED are used in the demonstration that can increase patronage more separately, can increase passenger's number with bright, the corresponding demonstration of whether going out of 1,2,3 highlighted LED.
Fig. 3 has provided a kind of arrangement form of display.
Fig. 4 shows the system chart that is installed in the car internal controller, and the formation of described controller comprises: as the CPU of control core, the keyboard that is used to import links to each other with CPU, and CPU is connected with display.Described display adopts LCD or LED.The user can set out the travel direction of hiring a car and can increase patronage again by button and display, and the CPU in the car internal controller issues information the large LED array indicator that is installed on roof by serial ports then.
The car internal controller adopts the mode of input digit to determine the travel direction of hiring a car, the travel direction of a taxi of each digitized representation.Can the machine representation field direction as " 1 ", " 2 " represent the railway station direction ...And the roof indicator is closed in " 0 " representative.This mode provides a kind of quick input mode for the driver.
CPU in the led array indicator is 89C52, and the CPU in the car internal controller is 89C55.
In addition, here with the embodiment of the present utility model detailed explanation that has been center deployment, the imbody of described optimal way or some characteristic, should be understood to this instructions only is to describe the utility model by the mode that provides embodiment, in fact on some details of forming, construct and using, can change to some extent, comprise the combination and the assembly of parts, these distortion and application all should belong in the scope of the present utility model.
