The concrete course of work is as follows:
A kind of frequency-modulated broadcast transmitter of intelligent monitoring is by forming with the lower part:
1, RS232 interface: be connected with UPS, frequency modulated transmitter, in real time fetch equipment operational factor and equipment realized the part controlled function.
2, AD interface: be connected the analog quantity parameter that real-time sampling equipment provides with power amplifier.
3, digital quantity interface: be connected with equipment such as frequency modulated transmitter, power amplifiers, in real time the digital quantity parameter that provides of fetch equipment and equipment realized the part controlled function.
4, audio unit: audio signal is sampled and compressed.
5,3G transmission unit: adopt 3G wireless transfer channel and local machine room to connect swap data.
6, power subsystem: adopting uninterrupted power supply is system's power supply, guarantees the normal operation of supervisory control system.
The equipment of supervisory control system far-end behind electrification reset connects by the main frame that the 3G radio-cell dials up on the telephone with local machine room earlier, fails then supervisory control system can be notified person skilled system start-up failure by way of short messages if connect; After successfully connecting, system sends to current equipment operation situation and various parameter on the main frame.
The parameter of equipment such as the timing sampling of system's meeting subsequently UPS, satellite receiver, exciter, power amplifier, the ruuning situation of judgment device, and the equipment operation parameter is sent to main frame according to the time of host setting, and file in order to main frame, do further statistical work.If the operational factor of supervisory control system discovering device has exceeded preset threshold, send alarm command and pass through the SMS notification person skilled to main frame at once.
The state that supervisory control system should be moved according to the switching on and shutting down timetable judgment device of setting, realize facility switching machine state automatic switchover.
Supervisory control system receives the order that main frame sends at any time, can set the output volume of satellite receiver, sets the power output of exciter, the power output of setting power amplifier.And the parameter of each equipment carried out real-time sampling, and the monitoring threshold of each equipment is set, split the unused time table and make amendment, monitor the ruuning situation of uninterrupted power supply in real time.
