OSD video character overlay performance parameters and applications

OSD video character overlay can choose traditional BIG5 encoding font, the default national standard 2312 simplified font, can overlay traditional characters and customize any language font. This is our company's independent research and development, production and sales, quality assurance, low price, the appearance of this product greatly reduces the user's cost of use, OSD video character overlay users do not need to understand the knowledge of video overlay, only need to know the serial communication Do video overlays. OSD video character overlay is a general-purpose device dedicated to video overlay. It can work in internal mode (module generates video signal, can generate color background, color text) and external mode (white text, superimpose external video, can draw black border). In this mode, the communication interface RS232, SPI, TWI, onboard real time clock, date and time can be set independently whether to display, location color size, etc. Item No .: OM9024 Specifications: Set weight: 100 grams.

OSD video character overlay performance parameters:

Input voltage: 7 ～ 9V (with voltage regulator on board), optional 5V
Communication interface: RS23, TWI, SPI, RS485 (optional)
Input level: CMOS / TTL / 485
Video impedance: 75 ohms Working temperature: -40 ℃ ～ + 85 ℃ (industrial grade)

OSD video character overlay product features:

Careful hardware design, stable and reliable display, clear image based on the powerful MB90092 character superposition chip design, can overlay text, pictures, animation
GB2312 font, no character limit, wider application
RS232 (TTL and CMOS level optional), TWI, SPI, RS485 (special instructions required)
Onboard RTC real time clock, practice and date can be independently set to display location color and size. Internal mode and external mode are optional. Video can be generated without inputting video. Users do not need to initialize. Standard video socket and industrial wiring terminal are used immediately after power on Convenient for free secondary computer (VB) secondary development source code, free RS232, SPI, TWI lower computer test code command format is simple, with communication control function expansion function control pin

OSD video character overlay application areas:
Video monitoring, security industry, elevator floor display, road and bridge monitoring, toll station, bank note monitoring, queuing system, large electronic display screen, temperature, humidity, time character overlay, industrial control site
GPS information overlay mobile video ads, etc.

Power Cable

Power cables are used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, internal power supply of enterprises, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.
In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system.
The structure of power cable is relatively simple, which can be divided into conductor, internal and external insulation layer, sheath, armor layer and protective layer. The conductor is mainly made of copper and aluminum, which is used to conduct current. The insulating layer is usually wrapped around the conductor to isolate the conductor and so on. There are various types of power cables. If they are classified according to voltage, they can be divided into low-voltage, medium voltage, high-voltage, ultra-high voltage and ultra-high voltage cables.

Advantages

1. Small land occupation. Generally, it is buried in the soil or laid indoors, in ditches and tunnels. The insulation distance between lines is small, without poles and towers. It occupies less land and basically does not occupy space on the ground.
2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
