Description of the drawings
Fig. 1 is the system block diagram of the present invention.
Fig. 2 is the operating process schematic diagram of the present invention.
Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As depicted in figs. 1 and 2, a kind of remote monitoring system, including remote control station, data transmission link, mobile platform,
Laser beam emitting device and laser receiver, the data transmission link, laser beam emitting device and laser receiver are set to
On mobile platform；The laser beam emitting device to the objective emission laser of monitoring for being monitored；The laser receiver
It connect the laser for receiving monitored target reflection with data transmission link, while transferring data to data transmission link；
The remote control station is wirelessly connected with data transmission link, for receiving and processing data.
It is worth noting that, the laser beam emitting device passes through three axis autostabiliazer units and mobile platform with laser receiver
It is connected and fixed so that the two devices are not disturbed by mobile platform movement, keep the stabilization of itself, while can pass through three axis
The orientation angle that autostabiliazer unit adjusts its irradiation and receives.
In the present embodiment, silicon photocell is equipped in the laser receiver for receiving laser, silicon photocell according to
The facula area of reflection laser changes situation and carrys out the corresponding corresponding voltage of output.
In the present embodiment, the voltage that amplification filter unit is used to generate silicon photocell is connected on the silicon photocell
