When the installation of the security system is basically completed, many projects will produce multi-line ripples during the debugging process after installing the LCD splicing wall screen. After the unremitting efforts of our engineering staff, we finally found the cause and solution. The following will analyze in detail. Symptoms: The picture has multi-line ripples Cause: Static electricity. Causes of static electricity: From a microscopic perspective, according to the theory of atomic physics, a substance is in an electrical equilibrium state when it is electrically neutral. Due to the gain and loss of electrons generated by the contact of different substance electrons, the substance loses its electrical balance and generates an electrostatic phenomenon. Macroscopically speaking, friction between objects generates heat, stimulates electron transfer, contact and separation between objects generates electron transfer, electromagnetic induction causes an unbalanced distribution of charge on the surface of the object, and a combined effect of friction and electromagnetic induction. The chief culprit of static electricity is the static voltage, which is generated by the contact and separation of different kinds of substances. This effect is known as triboelectric charging, and the voltage generated depends on the characteristics of the materials that rub against each other. Because the actual production process of the DID LCD splicing display is mainly due to direct contact and indirect contact between the human body and related components, static electricity is generated. Therefore, according to the characteristics of this industry, we can do some targeted static electricity prevention measures. solution: The generation of static electricity is a natural law. We cannot completely eliminate it, so we can only put forward some suggestions to prevent static electricity. Installers must observe the following points during the installation process. 1. Grounding Grounding is the direct discharge of static electricity to the ground through the wire connection. This is the most direct and effective anti-static measure. For conductors, grounding is usually used. The main cabinet and the DID LCD splicing screen are connected to the ground one by one. 2. Insulation Insulation is to paste the insulating tape as far as possible between the DID LCD splicing screen and the metal and power connection to prevent static electricity. Third, the line is separated from the line Separating the cable from the cable means that the VGA cable and the power cable are separated. We all know that the VGA cable we use generally has no shielding layer. The VGA cable without the shielding layer and the power cable are easy to produce static interference The above are the most basic points to prevent the generation of static electricity, but there are actually many, for example, our installation and debugging personnel and other personnel who will touch the related equipment must start work in accordance with the relevant matters of "Public Security System Installation" In order to contact the relevant equipment, the static electricity of the human body should be discharged in advance, to prevent the voltage of the human body from affecting the relevant parameters of the machine and bringing unnecessary trouble to the installation and debugging.
