Abstract

The utility model provides a controlling device for an LED taxi toplight, comprising an LED taxi toplight, an evaluating device, a fee register, an alarm press button and a GPS/GPRS vehicle-mounted terminal, wherein the input terminal of the LED taxi toplight is correspondingly connected with the fee register and the GPS/GPRS vehicle-mounted terminal respectively, the output terminals of the evaluating device and the alarm press button are connected with the input terminal of the GPS/GPRS vehicle-mounted terminal respectively. The utility model has the advantages that the GPS/GPRS vehicle-mounted terminal receives the signal of a background and controls an LED lattice screen to display corresponding contents, the number of lighted five-pointed stars can be controlled by a GPS host, all signal transmission can be performed by a communication module, the controlling device has compact overall structure and is fixed reliably, by using the device, a passenger can easily identify whether the taxi is in an empty state or in a passenger-carrying state, and the passenger can know the service level of the taxi by the indicator lamp of the toplight.

Description

Taxi LED ceiling light control device

Technical field

The utility model relates to a kind of Multifunctional LED ceiling light control device of urban taxi.Belong to the taxi dome lamp technical field.

Background technology

At present, taxi dome lamp device profile on the market is coarse, function is simple, and there is not taxi empty and load status display function, the ceiling light device font display effect that has the state demonstration on a small quantity is overcautious, not attractive in appearance, at the not high weather of visibility such as rainy day, the passenger is difficult for recognizing the empty and load state of hiring a car.

Summary of the invention

The utility model proposes a kind of taxi Multifunctional LED ceiling light control device, its purpose is intended to overcome the function singleness that prior art is deposited, no taxi empty and load status display function and to defectives such as taxi industry monitoring functions.

Technical solution of the present utility model: it is characterized in that comprising LED taxi toplight, evaluator, fee register, alarm button and GPS/GPRS car-mounted terminal, corresponding joining of output terminal of the first input end of LED taxi toplight and fee register wherein, corresponding the joining of output terminal of second input end of LED taxi toplight and GPS/GPRS car-mounted terminal, the first input end correspondence of the output terminal of alarm button and GPS/GPRS car-mounted terminal is joined, corresponding the joining of second input end of the output terminal of evaluator and GPS/GPRS car-mounted terminal.

Advantage of the present utility model: power module is given the power supply of LED ceiling light, car-mounted terminal receives the signal of GPS/GPRS car-mounted terminal, control LED dot matrix screen shows content corresponding, the bright number of pentagram also can be by the control of GPS/GPRS car-mounted terminal, and all signal transmission are all passed through communication module and realized.Compact overall structure, fixing reliable, can reach good waterproof effect.Use this cover system, can make the passenger be very easy to distinguish taxi is in complete vehicle curb condition or is in the carrying state, and the passenger can only just understand the service star of taxi with the pilot lamp of ceiling light, so that the passenger selects to serve the high taxi of star, better promote taxi to improve the service quality of oneself.

Accompanying drawing 1 is that system realizes block diagram.

Accompanying drawing 2 is structural representations of LED taxi toplight.

Accompanying drawing 3 is 8 * 8 circuit diagrams such as matrix LED.

Accompanying drawing 4 is schematic block circuit diagram.

Among the figure 1 is protecgulum, the 2nd, transparent panel, the 3rd, backlight luminous board, the 4th, bonnet, the 5th, display board, the 6th, base.

Embodiment

As shown in Figure 1, its structure comprises the LED taxi toplight, evaluator, fee register, alarm button and GPS/GPRS car-mounted terminal (evaluator, fee register, alarm button and GPS/GPRS car-mounted terminal all belong to prior art) corresponding joining of output terminal of first input end and the fee register of LED taxi toplight wherein, corresponding the joining of output terminal of second input end of LED taxi toplight and GPS/GPRS car-mounted terminal, the first input end correspondence of the output terminal of alarm button and GPS/GPRS car-mounted terminal is joined, corresponding the joining of second input end of the output terminal of evaluator and GPS/GPRS car-mounted terminal.Behind fee register conversion empty wagons/loaded vehicle state, signal to the LED taxi toplight, ceiling light shows empty wagons/loaded vehicle.If alarm button is triggered, the GPS/GPRS car-mounted terminal signals to the LED taxi toplight, ceiling light display alarm SOS information.Before the passenger gets off at every turn, can estimate this service by evaluator, evaluating data uploads to the backstage by the GPS/GPRS car-mounted terminal, the backstage is determined the service star by certain appraisement system to each taxi, and pass to the GPS/GPRS car-mounted terminal, GPS/GPRS car-mounted terminal control ceiling light shows corresponding pentagram quantity.Use this cover system, can make the passenger be very easy to distinguish taxi is in complete vehicle curb condition or is in the carrying state, and the passenger can only just understand the service star of taxi with the pilot lamp of ceiling light, so that the passenger selects to serve the high taxi of star, better promote taxi to improve the service quality of oneself.

As shown in Figure 2, transparent panel 2 is bonded on the protecgulum 1, and backlight luminous board 3 is fixed on the protecgulum 1, and display board 5 is fixed on the protecgulum 1, and bonnet 4 is fixed into integral body with protecgulum 1, fixes at last on the base 6, and the rubber seal sealing is used in protecgulum and bonnet 4 borders.Compact overall structure, fixing reliable, can reach good waterproof effect.

As shown in Figure 3, power module is given the power supply of LED ceiling light, and car-mounted terminal receives the signal of GPS/GPRS car-mounted terminal, and control LED dot matrix screen shows content corresponding, the bright number of pentagram also can be passed through the GPS host computer control, and all signal transmission are all passed through communication module and realized.

As shown in Figure 4, its structure comprises MCU (controller AT89S52), power module (2576), driver module (HC595), lattice module (LS-2388AS83), communication module (RS232), the flash character library, corresponding joining of I/O end of the first output/input end of MCU and communication module wherein, corresponding the joining of I/O end of the second output/input end of MCU and flash character library, the output terminal of MCU joins with the input end of driver module is corresponding, the power input of MCU joins with the power output end of power module is corresponding, and the output terminal of driver module joins with the lattice module input end is corresponding.

Controller sends to LED dot matrix screen and goes up demonstration for being responsible for that Chinese character or ascii character are converted to a horizontal and vertical parity check code.Power module is the power supply of total system; Each driver is made up of 16 HC595, and per two HC595 join end to end, and HC595 is a serial shift register, and first HC595 shifts to next HC595 with data, and the like, data are moved to the 16th.Each LED lattice module by 16 (OK) *, 32 (row) totally 512 light emitting diodes form; The brightness of each luminotron is 1500MCD (linear module of light intensity).
