Description: TV and FM transmitters monitoring control management system
 

TV and FM transmitters monitoring control management system
The system adopts the most advanced and sophisticated technology, the control center can connected with one or more transmitters through the serial communication interface and network communications equipment to monitoring them in real-time in local or remote. It can analyses, controls; records automatically and diagnoses alarm etc.

The system supports Windows XP/NT/2000 operating system, and established on the common platform of industrial monitoring system, with the self-development man-machine interface operating software.

This system is especially suitable for FM radio transmission with multi-point, wide-ranging and the stations with less people or no people. It can save human resources, reduce the inactive time from the transmitter malfunction, prevent incidents of vandalism and raise the level of integrated management.

1. System composition:
There are two parts in this system: Control center server (and its terminal PC in the LAN), transmitter room (remote and local) data acquisition and control equipment.

2. Functions Description:
1. Transmitter immediately switch machine.
2. Transmitter schedule switch machine.
3. Transmitter automatically switch machine (timing).
4. Analysis, control, record automatically and diagnostic alarm etc.
5. Data collection in real-time, display and control the equipment operation in transmission room.
6. Transmission system automatically alarm.
7. Provide efficiency historical data, real-time data, alarm data; Query and print reports.
8. Automatically count each transmitter’s day run-time and cumulative run-time.
9. Permission and security management.
10. Provide a wealth of operating curve (chart) with real-time and historical data.

System features and extensions:
1.    Coaxial switch (Host/standby machine automatic/manual switching).
2.    Public network View the monitor screen from the network.
3.    Room monitoring and program monitoring.
4.    SMS data collection and switch machine control.

System features:
1.    Plug-in architecture, it is easy to make a network.
2.    Great compatibility, it can manage various different type transmitters at the same time.
3.    Redundant design for expansion, strong network function.

3. Management software of Monitoring and Control System
It can monitory, control and applause alert (it uses sound and light to alarm watch people in local area, it uses mobile phone message to notice maintenance people) to the parameters of exciter, amplifier, satellite receiver and antenna system in local and remote, system query, monitoring the scene image of transmission station in real-time, monitoring the signals from the transmitters.

Monitoring and Control System software is divided into: stand-alone version and network version. The stand-alone version can just monitory the transmitter on LAN or in local; the network version can monitory the remote transmitter by linked with the Internet. With the condition in authorization, you can land the network and browse, query transmitters’ operating parameters in each station. The majority of connection is the composite network.

4. Technical Specifications:
1. The number of monitoring equipment:      ≥100 sets
2. Monitoring the key parameters:
The returning frames of image in real-time: 1-30F/S adjustable
The returning delay of sound in real-time:  <3 S
Failure alarm delay time:                   <30 S
Alarm accuracy:                             >99%
