First, switch LED electronic display notes:
1, the switching sequence:
When opening the screen: first boot, after opening the screen off screen: first off the screen, after the shutdown (the first off the computer does not turn off the display, will cause the screen body highlights, led burned lamp, the consequences are serious.)
2. The interval between switching screens should be more than 5 minutes.
3. After the computer enters the engineering control software, it can turn on the electricity.
4, to avoid opening the screen in full white screen state, because at this time the system's maximum inrush current.
5. Avoid opening the screen in an out-of-control state because the system's inrush current is maximum.
A computer does not enter the control software and other programs;
B computer is not powered;
C Control section power is not turned on.
6. When the ambient temperature is too high or the heat dissipation conditions are not good, the led lighting should be careful not to open the screen for a long time.
7. When one part of the screen body is very bright, it is necessary to pay attention to closing the screen in time. It is not appropriate to open the screen for a long time in this state.
8, often appear on the display power switch tripping, should promptly check the screen or replace the power switch.
9. Regularly check the firmness of the attachment. If loose, pay attention to adjust in time and re-strengthen or renew the hanger.
10. According to the environment of the large-screen display screen and the control part, avoid insect bites, and if necessary, place anti-rat poison.
Second, the control part of the changes, changes Note 1, the computer, the control part of the power line zero, the fire can not be reversed, should be strictly in accordance with the original location of the plug. If there are peripherals, after the connection is complete, test whether the chassis is powered.
2. When controlling devices such as mobile computers, check the connection lines and the control board for looseness before powering on.
3, can not arbitrarily change the communication line, flat connection line position, length.
4. If abnormalities such as short circuit, trip, burning line, and smoking are found after moving, the power test should not be repeated and the problem should be promptly searched.
Third, the use of software operation Notes 1, software backup: WIN7, WINXP, applications, software installation programs, databases, etc. It is recommended to use "a key to restore" software, easy to operate.
2, mastered the installation method, the original data recovery, backup.
3, master control parameter settings, basic data preset modifications 4, skilled use of procedures, operations and editing.
5, regular inspections, delete unrelated data 6, non-professional staff, do not operate the software system.
The LED Trunking System is divided into two parts, one is the trunking, the other is the functional component. At present, for trunking, we have 3 wires, 5 wires, 7 wires, 8 wires and 11 wires. The functional components include the emergency driver, Motion sensor module and track module.
The discription of all types of trunking.
