          LED display maintenance method

          LED display maintenance method Full-color LED displays are also like traditional electronic products. Not only do they need to pay attention to methods during use, but they also need to perform maintenance on the display screen to make the LED display life longer. The increase in the use of LED full-color display screens, on the one hand, is due to the fact that major manufacturers have reduced the amount of work materials used to control production costs, which has led to premature aging of a few parts of some products; The reason on the one hand is due to the user's improper use habits. The latter is more common than the latter. Here are the top ten ways to maintain LED full-color displays.

          1. Keep the humidity of the environment of the full-color LED display. Do not allow anything with moisture properties to enter your full-color LED display. Powering a full-color display that contains humidity can cause corrosion of the full-color display components and cause permanent damage.

          2, to avoid possible problems, we can choose passive protection and active protection, as far as possible on the full-color display screen can damage the items away from the screen, and clean the screen as much as possible to gently wipe, to hurt The possibility is minimized.

          3, LED full-color display and our users the most close relationship, do a good job of cleaning and maintenance is also very necessary. Exposure to the outdoor environment for a long time, such as wind, sun, dust, etc., is easily dirty. For a while, the screen must be dusty. This requires timely cleaning and long-term surface coverage with dust-proof soil.

          4. It is required that the power supply be stable, and that the grounding protection be good. Do not use it under harsh natural conditions, especially strong lightning weather.

          5, the screen body is prohibited from water, iron powder and other conductive metal. The LED display screen should be placed in a low dust environment as much as possible. Large dust will affect the display effect, and too much dust will damage the circuit. If water enters for various reasons, immediately switch off the power and contact maintenance personnel until the display panel inside the screen is dry.

          6, LED display switching sequence:

          A: Turn on the LED display first after turning on the control computer so that it can operate normally. B: Turn off the LED display before turning off the computer.

          7, do not play for a long time in full white, full red, full green, full blue and other bright screen, so as not to cause excessive current, power line heat is too large, LED lamp damage, affecting the display life. Never disassemble or splicing the screen!

          8. It is recommended that the rest time of the LED display is greater than 2 hours per day. In the rainy season, the LED screen should be used at least once a week. Normally, the screen is turned on at least once a month and lighted for more than 2 hours.

          9, led display surface can be wiped with alcohol, or use a brush, vacuum cleaner dust, can not be wiped directly with a damp cloth.

          10, led display need to regularly check whether the normal work, the line has no damage, such as not to be replaced in time, the line has to repair or replace the damage. Led display internal lines, non-professionals are forbidden to touch, in order to avoid electric shock, or cause damage to the line; if there is a problem, ask a professional to overhaul.

          Base site lead-acid battery protector system is the smart resonance pulse technique for 6V/36V cell battery or 6V/36V battery pack in series with 3PCS 2V/12V cells. It is working as a new generation of high-tech products for daily battery maintenance in telecom base site or electrical power system.
          It utilizes the energy from battery self-power or floating power supply, to produce a unique smart electronic pulse, then feed back to the battery through the output line, Resonance with coarse and hard lead sulfated crystals in negative plates of batteries and converted to active substance under the reaction of pulse charging current which dissolve lead sulfated crystals, Keeping the battery working at a high efficiency. Under the disturbance by the smart resonance pulse, the new lead sulfate crystal is prevented from being formed, and the service lifespan of the lead-acid battery is prolonged 1~2 times than before.
          There will be individual differences in State-Of-Capacity (SOC) and internal resistance (IR Value) of batteries after used for a certain number of years. It is called the battery unbalancing. Due to the total floating charge voltage of the rectifier remains unchanged and keeps constant, when the battery pack is in floating charging status, the floating voltage of the cells with larger internal resistance will be higher than that of the normal battery, resulting in the normal battery's floating voltage is lower. Batteries floating charged in this unbalancing way for a long time will cause the higher voltage cells seriously water dehydrated, and the lower voltage cell is in a state of under charged. This way of vicious spiral formed will accelerate the base site batteries premature failure.
          Our protector system set a equalized charging function. If the terminal floating voltage of the battery system is higher than the standard value of protector system designed, the system automatically and smartly switches to the over-voltage balanced working state. When the voltage drops lower than standard value, it automatically changes to smart pulse maintaining state. The decrease of battery internal resistance and the improvement of the battery equalization lead to the battery lifespan prolonged.
