Remote control of the screen:

If you want to control your screen by internet, we will provide advertising software which enables internet streaming by a wired or wireless network. 

The system is based on a Browser/ Server platform. With a server installed in the internet or Ethernet, user can login the system just by enter the IP address of the server, and then upload and publish the video, images or text on the display. This B/S structure software maximum the flexibility to control the screen. 

Based on module design, the function is powerful and user friendly:

Layout Design Module
Sophisticated graphical scheduling, playing list planning, drag and pull drawing constitute the base module. Template lay-out or industry standard application can either be routed to the intended PowerNet player or per your plan. This is all you need to get started with your own digital billboard project.

Content Management Module
Content elements are easily managed within the graphic, text and video types’ folder. Prior to the media contents published to the audiences, supervisors may validate the campaign by content review, playing list confirmation and then decide to upload the files to the network.

Group Node Administration
This allows the creation of groups of nodes so that different kinds of content, schedules, and media program can be managed on a group level. Leave it to the system to propagate correct content to the correct groups.

System Administrator Module
If you need create your user accounts (unlimited numbers), change the roles of users or remotely tune individual node parameters, such as audio levels, display output parameters, etc. This module gives you those abilities.

Remote Management Module
This is the ability for a system administrator to monitor and manage the Network LED player to remote control. A complete system consists of a program that facilitates the continuous of variables such as microprocessors utilization, content element’s size and the network MAC address. The Program also allows for such remote operations as rebooting, shutdown, troubleshooting, on (off) line status, and video volume control. A single system can be used with more than one server with out the need for on-site staff at any of the player’s locations.

Reporting Logs
This module enables logging of every system event. It permits the creation of an audit trail for all schedule entries that are played, all exceptional situation that relate to the health of the nodes, network or content.

SERVER REQUIREMENT:

In order to find the server in internet, the server should have a static IP address. When the system runs in Ethernet, the server also needs a interior static IP address. Two situations for wireless control:

1st. The control PC connect to internet through a wireless network
In this occasion, the computer can be placed outside the control room, such as in the display frame. Operator can control it via a laptop. Diagram shows as below:

2nd. the control PC connect to a wired network

The operator can control the display by a wireless internet.

Power distribution Unit:

Power distribution Unit for LED Screen: **KW

Power need for control room: *KW.

Power Supply:  AC 380V, three-phase five-wire system

Voltage range: normal±15%

FUNCTION

  1. All hardware devices are complying with CE certification.
  2. The Power Distribution unit is controlled by the programmable logic controller, and power load draw power from grids step by step. In this way, it will reduce the current impact for power grids caused by the LED screen system.
  3. Programmable logic controller communicates with computer, start instruction is issued by the operation computer without manually switching button. At the same time the status information and fault information of the main switch is sent back to the computer network, by which the network can monitor the power switch.
  4. By adding over-current, short circuit, open circuit, overvoltage, under-voltage, temperature and other protective devices, and adding the necessary instruction equipments, the power distribution unit can facilitate the inspection of faults and has anti-static, anti-seismic and other functions.
  5. Protection ground wire to earth resistance is less than 4 ohms, the earth resistance of electronic communication equipment is less than 1 ohm ,it adopts the three-phase five-wire power supply system. Also a signal ground is needed, which is independent of the protective ground; it can be used by the network systems and distributed control systems. Power lightning protection depends on LED screen, line lightning protection design and distribution system solutions.
