The application of LED display on the traffic makes the car LED display popular in abundance. The car screen appearing in the streets and lanes also makes us add a lot of color to the daily life of the traffic. What kind of characteristics? Here we make a simple analysis of the LED brightness, power supply, protection measures and other technologies of the car display.
First, LED brightness attenuation:
LED attenuation characteristics, LED brightness is attenuated, 10-70% attenuation rate in a year, half-year brightness is reduced by half in poor quality, making it impossible to see the display content.
Second, stable power system support:
The power supply on the car is powered by a battery. When the car starts, brakes, and stops, it will generate a high pulse voltage. If the power system is not good, it will burn the LED display.
Third, high stability and reliability:
Cars are always moving, and they require high stability and reliability of electronic products.
Fourth, good anti-static measures:
The car is prone to static electricity during operation, especially in the fall, the electrostatic high voltage can reach thousands of volts, if there is no good anti-static measures, it is easy to damage the IC and LED lights.
Fifth, the brightness is appropriate:
Appropriate brightness; if the brightness of the LED display is not enough, it will not be visible during the day, and the meaning of installing the display will be lost; if it is too bright, it will affect the driving.
6. Ultra-large range transmission:
Can provide anywhere with a network of telecom operators.
Common wireless car LED display modes are as follows:
1. Directly edit the way of SMS messages to send messages to the wireless SMS screen. This method is suitable for customers who have a small number of screens and can send information anytime, anywhere.
Second, send information to the wireless short message display through the Internet, its characteristics are: editing information is convenient and fast, no need to buy SMS sender. Suitable for customers who have a large number of screens and can easily access the Internet.
Third, use the computer to send information to the wireless short message display through the mobile phone transmitter. Its characteristics are; editing information is convenient and fast without internet access. Suitable for customers who have a large number of screens and cannot access the Internet.
The built-in GPRS module is equivalent to an Internet user and is dynamically assigned an IP address each time it is powered up. In this way, using any computer connected to the Internet, the wireless LED display software can be used to send information to the LED display. Basic requirements:
1. The user's computer terminal requires access to the Internet through wireless or wired means.
Second, the user computer interrupt needs to install wireless LED display to send software.
Third, if users establish their own service network, they need to apply for a fixed IP address and ensure that the service is online in real time.
Fourth, the transmission of information through the GPRS network, low cost, good real-time, suitable for the transmission of large-capacity text information or image information content.
5. The radio paging screen has a built-in paging receiver, which can receive and display information anytime and anywhere within the coverage of the paging station signal. The information can be transmitted in a simple and timely manner by dialing a page or using a wireless information distribution system.
