Abstract

The invention discloses a device and method for immediately controlling a third-party display screen. The device comprises a master controller, a third-party control card, a third-party display screen control card and the third-party display screen. Text signals or voice recognition signals are input at a master control end, and the master control end transmits data to the third-party control card through a wired or wireless network. The third-party control card is used for receiving and decoding the signals sent by the master control end and transmitting the decoded signals sent by the main control end to the third-party display screen control card, and the third-party display screen control card generates a display signal and transmits the display signal to the third-party display screen for display. The third-party control card comprises a controller, a voltage-stabilizing power supply module connected with the controller, a 485 interface circuit, an RS 232 interface circuit, a storage module, a wireless communication module and a dot matrix display interface circuit. The device is high in universality, can publish electronic display screen information in real time, is easy to learn and can be used in outdoor advertisement display screens and taxi systems.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a device and method for real-time control of a third-party display screen. Background technique [0002] In the existing taxi LED screen control system, the corresponding control software is installed on the computer in the remote control room, and the remote staff edits the content on the software, transmits the signal through the wireless network, and displays it through a set of control in the screen body. The control card of the screen decodes the received signal, and then through the control drive circuit of the display itself, drives the brightness or darkness or gray level of each LED of the LED display to achieve the desired display effect. With such a system design, the content of the display screen on the top of the taxi is completely operated by the personnel in the remote control room. The control room of a taxi company controls multiple taxi LED screens, and the con...
