Abstract
The utility model relates to a wireless video system of a container crane, which is characterized by comprising a video signal coder, a first switchboard, a wireless emitter, a wireless receptor, a second switchboard, a video signal decoder and a video system, wherein the video signal coder is connected with an external video signal output point and used for converting external simulating video signals into digital video signals; the first switchboard is connected with the video signal coder and the wireless emitter; the wireless receptor is matched with the wireless emitter for use; the second switchboard is connected with the wireless receptor; the video signal decoder is connected with the second switchboard, arranged in a cab of a dolly, and used for converting the digital video signals into the simulating video signals; and the video signal decoder is connected with the video system in the cab of the dolly. Compared with the prior art, when a dolly system of the crane and an external connecting cable adopt a sliding contact wire for power supply, the video conversation function between the cab of the dolly and the outside can be realized in a wireless manner.
Description
Technical field
The utility model relates to the video system of container handling crane, particularly relates to a kind of wireless video system of container handling crane.
Background technology
At present; Move the change of power supply mode along with the container handling crane dolly; Originally traditional drag order or drag chain mode progressively move the power supply conversion to trolley, and dragging originally makes various cables such as having comprised power cable, control cable, telephone cable, vision cable in the cable, supplies with electrical source of power on the travelling car, control signal, telephone signal, vision signal etc. respectively; When drag make power supply mode change the slide wire power supply mode into after; Electrical source of power is wherein supplied power by trolley, and other various signals comprise that control signal, telephone signal, vision signal all need insert dolly through other modes, to guarantee the dolly normal operation of container handling crane.Container handling crane video system originally adopts analog video signal, transmits through coaxial cable or optical fiber mode, is mainly used in heavy mechanical equipment or industrial and mining enterprises field; When dolly adopted trolley, the driver's cab on the dolly must adopt other modes to accomplish with outside function of carrying out video communication.
The utility model content
The utility model technical matters to be solved is the wireless video system that a kind of container handling crane is provided to above-mentioned prior art; When the cart system of hoisting crane and exterior connecting cable change into when adopting slide wire power supply, can realize chauffeur chamber and external video communication function through wireless mode.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the wireless video system of this container handling crane is characterized in that: comprise
With the videocorder that the outer video signal output point links to each other, be used for converting exterior analog video signal to digital video signal;
First exchange that links to each other with videocorder;
The wireless launcher that links to each other with first exchange;
The wireless receiver that matches and use with said wireless launcher;
Second exchange that links to each other with wireless receiver;
The video signal decoder that is arranged on the chauffeur chamber that links to each other with second exchange is used for converting digital video signal to analog video signal; This video signal decoder links to each other with the indoor video system of chauffeur.
As improvement, carry out the transmission and the reception of signal between said wireless launcher and the wireless receiver through leaky wave cable and antenna, wherein wireless launcher links to each other with the leaky wave cable, and wireless receiver links to each other with antenna.
Said videocorder sends to said first exchange through ethernet with digital video signal; Second exchange sends to video signal decoder through the ethernet form with digital video signal.
Compared with prior art, the advantage of the utility model is:
1, under the situation of the video system mode of operation that does not change other substation, after the power supply of trolley system is adopted in the dolly power supply, adopt the utility model scheme can guarantee reliably that driver's cab video system and external video output point carry out video communication;
2, after vision signal becomes digital signal through the videocorder module converts; Export the back through the mode of ethernet and insert first exchange; The signal of communication of the PLC in electric like this room and dolly PLC also can insert this first exchange; Make plc communication signal and vision signal be integrated into same wireless launcher and carry out the signal transmission, can effectively practice thrift transmission cost;
Metal mask and interference problem when 3, analog video signal converts the wireless transmitting system that adopts the leaky wave cable behind the digital video signal to and avoided point-to-point transmission over radio; Because container handling crane is an all-metal construction; If when adopting the wireless video mode to carry out point to point wireless communication, the phenomenon of signal interruption or interference unavoidably can appear when dolly is in operation.
Description of drawings
Fig. 1 is the wireless video system structural representation of container handling crane among the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to the wireless video system of container handling crane shown in Figure 1, it comprises
With the videocorder that the outer video signal output point links to each other, be used for converting exterior analog video signal to digital video signal;
First exchange that links to each other with videocorder;
The wireless launcher that links to each other with first exchange;
The leaky wave cable that links to each other with wireless launcher;
The wireless receiver that matches with said wireless launcher and to use, this wireless receiver links to each other with the antenna that can receive the signal that the leaky wave cable sends;
Second exchange that links to each other with wireless receiver;
The video signal decoder that is arranged on the chauffeur chamber that links to each other with second exchange is used for converting digital video signal to analog video signal; This video signal decoder links to each other with the indoor video system of chauffeur.
Above-mentioned videocorder sends to said first exchange through ethernet with digital video signal; Second exchange sends to video signal decoder through the ethernet form with digital video signal.
