Problems solved by technology

The disadvantages of this operation method are: (1) During the test, the operator needs to visually inspect the power display value according to the SPEC to make a judgment, and at the same time step on the pedal to move out of the station, which not only wastes labor, but also has a long waiting time for production and reduces production efficiency. Low; (2) The existing technology is judged by manual operation, there are misjudgments by personnel operation, and there are hidden dangers of missed judgments

Abstract

The invention relates to a system and a method for automatically testing power of display equipment on a production line. The system of the invention comprises a communication card, a main control computer, a power meter, a frequency converter and a PLC controller, wherein the PLC controller is arranged on the production line. The system and method control the power meter through serial communication of the main control computer to test the power of the display equipment, and control the actions of automatic entry detection, automatic exit, and the like of the display equipment through parallel port communication of the computer by the communication card and the PLC controller. The system and method can save labor force, improve the degree of automation, improve the production efficiency,and are favorable for preventing operating personnel from misjudging and failing to judge, thus preventing products from having quality problems.

Description

technical field [0001] The invention relates to an automatic power test system and method for display equipment on a production line. Background technique [0002] In the production of display equipment such as LCD monitors and LCD TVs, it is necessary to test whether the energy consumption of the display equipment in normal operation and energy-saving mode is qualified according to Energy Star or other standards. It is specifically divided into two parts: one is the power of the whole machine in normal operation The power required for the display to display a full white screen under the specified settings (brightness and contrast are factory settings); the second is the power in energy-saving mode. The power required for the display to automatically enter the energy-saving mode when there is no signal input . The overall power of the normal work and the power of the energy-saving mode are an important parameter to measure whether the display is energy-saving and environmen...
