If you don't know how to use it correctly, it will lead to a decrease in the life of the display screen. How to use the LED display screen exactly? The following YONGS LED display editor will share the following points for you, hoping to help you.
1. Precautions for switching LED electronic display screen:
(1) Switch sequence:
When the screen is turned on: first power on, then turn on the screen.
When the screen is turned off: turn off the screen first, then shut down
(Turn off the computer first without turning off the display screen, which will cause the screen to show bright spots, waste the lamp, and endanger it.)
(2) When the screen is switched on and off, the interruption time should be greater than 5 minutes.
(3) After the computer enters the engineering control software, the screen can be turned on and powered on.
(4) Prevent the screen from being turned on in a completely white screen state, because at this time the system has the largest impact current.
(5) Prevent the screen from opening in a runaway state, because at this time the system has the largest strike current.
A computer does not enter the control software and other procedures;
B computer is not powered;
C control unit power is not turned on.
(6) When the ambient temperature is too high or the heat dissipation conditions are not good, care should be taken not to open the screen for a long time.
(7) When one line of the electronic display screen is very bright, you should pay attention to closing the screen in real time, and it is not suitable to open the screen for a long time in this state.
(8) The power switch of the display screen is often tripped, and the screen body should be checked or the power switch should be changed in real time.
(9) Check the stable environment of the connection place on a regular basis. If there is any looseness, pay attention to real-time adjustment, and re-strengthen or update the hanger.
(10) According to the large screen display screen and the environment where the control department is located, to prevent insect bites, anti-rat drugs should be arranged when necessary.
2. Changes in the control department and matters needing attention for changes
(1) The zero and fire of the power cords of the computer and the control department cannot be reversely connected, and should be connected in strict accordance with the original position. If there are peripherals, after connecting, you should test whether the case is live.
(2) When moving control equipment such as computers, check whether the connecting wires and control boards are loose before powering on.
(3) Do not tamper with the position and length of communication lines and flat connecting lines at will.
(4) If there is any abnormality such as short circuit, tripping, burning wire, and smoke after moving, the power test should not be repeated, and the problem should be found in real time.
3. Precautions for the use of software monopoly
(1) Software backup: WIN2003, WINXP, application program, software installation program, database, etc.
Initiate the use of the "one-key restore" software to dominate the convenience.
(2) Familiar with installation methods, original data restoration and backup.
(3) Master the setting of control parameters and the modification of basic data presets
(4) Skilled use of procedures, domination and editing.
(5) Check viruses regularly and delete irrelevant data
(6) Non-professional personnel, please do not dominate the software system.
4. Common obstacles and solutions
(1) The display screen does not display:
A: Check the power supply environment of the screen body, and use a test pen or a multimeter to check whether there is electricity at the electrical terminal of the switch. There may be a problem with the switch, or a short circuit.
B: For the display screen synchronized with the computer, first check whether the computer has entered the sleep state; if it enters the sleep state, first enter the "control panel", click "power management", and select the "system expectations" and "closed monitor" options "Never" option, so that the computer will not sleep, and the display screen can work normally; if it does not enter the sleep mode, you can open the case to check whether the control card and the communication cable are connected smoothly, and check whether the communication cable is disconnected. Basically solve the above problems.
(2) Incomplete documents or incorrect location errors:
A: First, check whether the parameters of "display position" and "screen size" in the software are consistent with those given by the installation engineer. If you don't remember, you can count the length and width of the pixels on the screen. After the "body size" is determined, you can go to the screen to see how much the performance area is different, and then return to the computer to adjust until the position matches.
B: If the performance is not comprehensive, check whether the size of the file is consistent with the "screen size" of the screen.
C: Open the case to check whether there is a conductor on the control card.
(3) The communication screen fails to communicate:
A: Check whether the parameters in the software are consistent with those given by the placement engineer.
B: Check whether the serial port is firmly connected, and whether the communication line is disconnected.
(4) The screen is shaking and there are horizontal bars:
Check whether the common ground wire connected to the computer is loose, or whether the communication cable is loose. If the dominant person cannot determine the cause of the problem decisively, or does not know much about the computer, do not take the case apart.
