System for checking the operation status of the electric signboard in operation and its check processing method

摘要

The present invention relates to a system for checking the operation status of an electronic circuit board and an inspection method for the same, and in the related art, a matrix pixel inspection means of the electronic circuit board is inspected while influencing the display form of the electronic circuit board, It is impossible to scientifically perform data management for the failure of the matrix pixels generated in a plurality of display boards. Therefore, the maintenance / repair, handling and management of such display boards .;The display unit 4 is provided in the display control unit 3 of the electric sign board display module 5 and when the display data is transmitted to the display unit 4 under the control of the microprocessor 31 of the display control unit 3, A display state data reception processing unit 1 for temporarily storing the display state data detected in the display unit unit 4 and transmitting the display state data to the microprocessor 31; And a display state data transmission processing section (2) for providing the display state data reception processing section (1) with the detected state data when the abnormal state is detected, and a check processing method thereof .
