Abstract
The utility model discloses a point-to-point wireless bridge application device, which comprises an outdoor directional antenna, an outdoor chassis, a main control center and a video encoder, wherein the outdoor directional antenna, the outdoor chassis, the main control center and the video encoder are connected; the main control center comprises a control computer, wireless bridges, a power amplifier and a switch, and the control computer, the wireless bridges, the power amplifier and the switch are connected. The point-to-point wireless bridge application device is provided with a pair of the wireless bridges, the bridges are only needed to be set into the same channel, if the channel of one bridge is changed, and the other bridge is changed into the corresponding channel automatically. The point-to-point wireless bridge application device is internally provided with an enhanced dual polarization adaptive technology between two points which are far away from each other in order to acquire a better transmission effect, thereby achieving a good concurrent processing capacity, and having the advantages of good performance, low capital investment in software and hardware equipment and easy maintenance.
Description
Technical field
The utility model relates to a kind of point-to-point wireless bridge application apparatus.
Background technology
Existing wireless telecommunications are set up comparatively complicated, except development server side will be arranged, also special-purpose client will be arranged.Under large-scale network, resource sharing is disorderly, management is more difficult, fail safe is lower.Due to outdoor cabinet not being set, be placed on outdoor accessory and can not get protection, run into bad weather, easily be damaged, bring heavy losses to network user.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of concurrent processing ability than good, performance good, investment soft hardware equipment fund is few, safeguard and be easy to point-to-point wireless bridge application apparatus.
For addressing the above problem, the utility model adopts following technical scheme: a kind of point-to-point wireless bridge application apparatus, comprise outdoor directional antenna, outdoor cabinet, Master Control Center and video encoder, described outdoor directional antenna, outdoor cabinet, Master Control Center are connected with video encoder; Described Master Control Center comprises controls computer, wireless bridge, power amplifier and switch, and described control computer, wireless bridge, power amplifier are connected with switch.
As preferably, described wireless bridge is provided with a pair of.
As preferably, described power amplifier adopts DZN-2400-2000 2.4g 11b/g 2w Bidirectional intelligent power amplifier.
The beneficial effects of the utility model are: because described wireless bridge is provided with a pair ofly, only need be arranged to identical channel to bridge, change a side channel, another is convenient can change to corresponding channel automatically.At the point-to-point transmission of apart from each other, in order to obtain better laser propagation effect, built-in enhancement mode dual polarization adaptive technique, just can reach the concurrent processing ability preferably, and performance is good, investment soft hardware equipment fund is few, safeguard easy advantage.
The accompanying drawing explanation
The theory diagram that Fig. 1 is point-to-point wireless bridge application apparatus of the present utility model;
The theory diagram that Fig. 2 is Master Control Center in point-to-point wireless bridge application apparatus of the present utility model.
Embodiment
Consult shown in Fig. 1 and Fig. 2, a kind of point-to-point wireless bridge application apparatus, comprise outdoor directional antenna, outdoor cabinet, Master Control Center and video encoder, and described outdoor directional antenna, outdoor cabinet, Master Control Center are connected with video encoder; Described Master Control Center comprises controls computer, wireless bridge, power amplifier and switch, and described control computer, wireless bridge, power amplifier are connected with switch.
Described wireless bridge is provided with a pair of.Described power amplifier adopts DZN-2400-2000 2.4g 11b/g 2w Bidirectional intelligent power amplifier.Described outdoor directional antenna adopts D-Link ANT24-1800 type.
Wireless network interconnection for outdoor remote website, need to be used in conjunction with the outdoor directional antenna of high-gain, and directional antenna can be realized point to point connect.Need in some cases to improve covering more at a distance with the power amplifier of 500mW.Due in the outdoor connection of carrying out point-to-point or point-to-multipoint, for the decay that reduces feeder line to improve the transmission performance of network, can use outdoor cabinet by wireless bridge, outdoorly for dot element and power amplifier device, be placed on wherein.High-speed link between wireless bridge makes the user to obtain than E1/TI circuit transmission speed faster with small cost, and value on demand is expensive and be difficult to the optical fiber cable of installing.Wireless bridge can be connected to the website of various discrete in a local area network (LAN), even they for example, are kept apart by various obstacles (highway, railway or cable and optical cable can't overcome water body, massif).Configuration and management options coordinate gain directional antenna that the transmission range that reaches 30 kilometers can be provided; 802.11b provides the data rate of 11Mbps at present, and 802.11a can provide the message transmission rate of 54Mbps in the future; The website that each is separated is repeatedly kicked into an independent local area network (LAN).
The beneficial effects of the utility model are: because described wireless bridge is provided with a pair ofly, only need be arranged to identical channel to bridge, change a side channel, another is convenient can change to corresponding channel automatically.At the point-to-point transmission of apart from each other, in order to obtain better laser propagation effect, built-in enhancement mode dual polarization adaptive technique, just can reach the concurrent processing ability preferably, and performance is good, investment soft hardware equipment fund is few, safeguard easy advantage.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
