Embodiment
Below in conjunction with accompanying drawing device part of the present invention is described in detail.
Key problem in technology of the present invention is to adopt microwave circuit to transmit the signal of digitized image, voice, control signal, form simultaneously on harbour, cabin.
Referring to Fig. 1, this system consists of: the harbour part: digital camera 1 is divided into two-way behind remote control switch 13, video distribution amplifier 10, one tunnel input monitor 3 is for site operation personnel's supervisory work situation, and another road input Compress softwares multiplexer 5 is sent by microwave transceiver 2.7 is PC, and 8 is digital telephone.
Control center's part: comprise and accept the microwave transceiver 2 that harbour transmits signal that compressed decompress(ion) multiplexer 5 input central controllers 6 are sent into control operation device 9 and monitor 3,15 then for dividing monitor.
Another key of the present invention is by comprising digital cabin surveillance equipment, can obtain the discharging dynamic image and the data of cabin, picture intelligence is the digitized picture that is synthesized into secondary imaging by the altitude signal that radar range finder comes flyback retrace to obtain at stockpile, through and the actual video coupling that obtains of camera revise, obtain the volume of windrow and extrapolate the weight of stockpile.
Described cabin digital detecting system is by being installed in harbour discharging radar range finder mechanically along directions X point by point scanning back and forth, progressively advance in the Y direction, the track synoptic diagram of the wave beam that obtains on charge level as shown in Figure 2, the synthetic three-dimensional image of altitude information of Z (Ri) direction that this position coordinates and radar range finder are obtained, referring to Fig. 5, Ri is the height that radar is accepted, Δ Si is the pixel of antenna scanning, Ri Δ Si is the stereo-picture on the display, Xn, Ym are sweep span, and the size of m, n is determined according to resolution requirement.Fig. 5 rotates the three-dimensional imaging figure that the inversed W-shape charge level obtains for will be above-mentioned obtaining imaging.
