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%

How far(long) the transmitter cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

EXAMPLE 5W FM Transmitter use in the city and hometown:

I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

Below are the approximate range of different power FM Transmitters. ( The range is diameter )

0.1W ~ 5W FM Transmitter :100M ~1KM

5W ~15W FM Ttransmitter : 1KM ~ 3KM

15W ~ 80W FM Transmitter : 3KM ~10KM

80W ~500W FM Transmitter : 10KM ~30KM

500W ~1000W FM Transmitter : 30KM ~ 50KM

1KW ~ 2KW FM Transmitter : 50KM ~100KM

2KW ~5KW FM Transmitter : 100KM ~150KM

5KW ~10KW FM Transmitter : 150KM ~200KM
