Problems solved by technology

[0002] Most of the LED lights used in the display modules of today's premium displays are ordinary lights with high power consumption and low brightness, and the driver chip is driven by constant voltage, which consumes a lot of power and the brightness of the display screen needs to be adjusted manually, which cannot be flexibly adjusted according to the brightness of the surrounding environment. Automatically adjust the changes, which may cause light pollution caused by untimely adjustment or waste of resources caused by excessive brightness
The technology of the controller is relatively backward, the control principle used is relatively complicated, the complicated components affect the stability, it is not easy to update the software and the cost is also high
Most of the alarm lights and lane lights are controlled by relays, which are easy to interfere with the control chip, and the stability and service life of the relay are lower than that of the semiconductor chip.

Embodiment 1

[0011] Main control chip 6, LED scanning control single-chip microcomputer 8, light detection chip 10, sound and light alarm driver chip 12, sound and light alarm interface 13, voice broadcast module 14, font memory chip 11, LED scanning driver chip 4, LED scanning driver The interface 5 and the communication level conversion chip 7 are all welded on the main control board to form a controller 17; the main control chip 6 is connected to the LED scanning control single-chip microcomputer 8; The module 15 is connected with the communication level conversion chip 7; the LED scanning control single-chip microcomputer 8 is connected with the photodetection chip 11, the font storage chip 12, and the LED scanning driver chip 4; the LED scanning driver interface 5 is connected with the display screen 1 through a signal line; The device 10 and the optical detection interface are placed on the box body 2 through a wired connection; the alarm device 16 is connected with the sound and ligh...

Embodiment 2

[0013] The fee display controller is connected to the control center computer of the toll station through RS232 or RS485 wired communication, so as to realize the network connection between the toll display and the weight scale, railing machine, and automatic toll collection microwave system.

[0014] When there is a vehicle announcement, the central computer sends the vehicle charging information received from other equipment to the main control chip 6 of the fee display controller through RS232 / 485, and the main control chip 6 immediately sends the display information to the LED scanning control single-chip microcomputer 8, The LED scanning control single-chip microcomputer 8 takes out the corresponding display content from the font storage chip 12 and transmits it to the display screen 1 for real-time display through the LED scanning driver chip 4 and the signal line. Module 15 takes the corresponding single-segment combination from the voice bank and converts it into an ana...

Abstract

The invention provides an energy-saving type fee displayer which comprises a display screen, a box body, a support, a controller, a main control chip, a communicating level switch chip and a work stock storage chip. The energy-saving type fee displayer is characterized by further comprising an LED scanning driving chip, an LED scanning driving interface, the LED scanning control single chip microcomputer, a photoreceptor, a light detecting chip, a sound-light alarm driving chip, a sound-light alarm interface, an alarm and a voice broadcasting module. The photoreceptor and the alarm are arranged on the outer side of the box body, and the controller is positioned in the box body. The photoreceptor can automatically sense external light situations. The voltage of a photosensitive circuit can change along different light intensities. The voltage change can reflect change of the environmental luminescence. The main control chip can detect the voltage change to adjust the PWM duty ratio of the output enable control end of an LED driving chip to change the luminescence of the display screen. Thus, light pollution due to the fact that the luminescence is not adjusted timely or resource waste caused by overhigh luminescence is avoided.

Description

technical field [0001] The invention relates to a display, in particular to a charge display. Background technique [0002] Most of the LED lights used in the display modules of today's premium displays are ordinary lights with high power consumption and low brightness, and the driver chip is driven by constant voltage, which consumes a lot of power and the brightness of the display screen needs to be adjusted manually, which cannot be flexibly adjusted according to the brightness of the surrounding environment. The automatic adjustment may cause light pollution caused by untimely adjustment or waste of resources caused by excessive brightness. The technology of the controller is relatively backward, the control principle used is more complicated, the components are complicated and affect the stability, and it is not easy to update the software and the cost is also high. Most of the control warning lights and lane lights are controlled by relays, which are easy to cause int...
