Abstract
This invention relates to a method and a device used in monitoring large area such as cities, which sets several located captive balloons suspending in the sky or airships as the monitor platforms in the sky of region necessary to be monitored, and shooting device are set on the platforms obtaining the ground image signals and transmitting them to a monitor center set at the ground to be displayed, since the camera collection points are set in the sky, each head can monitor several decades of sq.km and the monitor points are not many, it's convenient for monitoring the panorama of the city and finding out accidents such as fire, flood and traffic envent.
Description
Affiliated technical field the present invention relates to be used for the method and the device of large area region such as supervision of the cities.
The main means that background technology resembles the such monitoring large area region in city at present are at the critical junction in city or on the high constructure in city the shooting collection point to be set, and the vision signal of multi pass acquisition are delivered to Surveillance center carry out image and show so that entire city is monitored; Simultaneously, Surveillance center also can send control command signal and transfer to collection point control The Cloud Terrace and take the photograph zoom mutually by transmission circuit, and adjustment is taken the photograph phase angle and focal length to obtain high-quality vision signal.The maximum shortcoming of this monitoring is a video acquisition point insufficient height, even on the high constructure in city the shooting collection point is set, they highly also can only be at tens meters to more than 100 meters, and the image range of every camera lens collection is very limited.Can address this problem though increase the collection point, since the collection point increase, the also corresponding increase of monitoring image, thereby also bring the new difficulty that monitors inconvenience.Therefore, one jiao in the city that can overlook on the critical junction in the just city of existing supervision of the cities monitoring or the high-rise can not be monitored entire city.
It is that the such large area region in city is subjected to the collection point limitation in height and the incomplete problem of monitoring image that exists that summary of the invention the present invention will solve.
The present invention adopts following method to realize: in the regional sky of required monitoring several are set and are suspended in aerial monitoring platform, the camera head that is used for obtaining below ground image signal is installed on each platform, and the below ground image signal that the camera head on each platform is obtained transfers to the Surveillance center that is located at ground and shows so that monitor whole zone.Described air surveillance platform adopts fixed point captive balloon or dirigible.Because the shooting collection point is located in the air, highly high, the image range of collection is big, and every camera lens can be monitored tens square kilometres, and the used monitoring collection point of entire city is few, can monitor the city overall picture, convenient again supervision.
The present invention is used to realize the device of said method, comprise several control points and the Surveillance center that are arranged on required guarded region, each control point is equipped with camera head, Surveillance center is equipped with corresponding image display device, have between each control point and the Surveillance center to be used for the wired or wireless transmission circuit of images signal, it is characterized in that described control point is located at the overhead air surveillance platform in zone that is suspended in required monitoring.
Described air surveillance platform adopts fixed point captive balloon or dirigible.
It also comprises some aerial mobile monitoring platforms that are made of the remote control airship that cruises.When running into accident in the surveillance area, can tracking target and the local monitoring of increase collection point by aerial mobile monitoring platform.
Because the present invention adopts aerial shooting mode that the city is monitored, have that the collection point is few, coverage is big, the comprehensive advantage of clear picture, can in time find accidents such as fire, flood danger, traffic accident, be convenient to manager's commanding and decision-making, also can be used to urban planning, cadastration, air traffic control simultaneously, broadcast live that relaying, cityscape are taken in the air, crop yield prediction and multiple uses such as the prevention and control of plant diseases, pest control, forest fire protection.
Description of drawings Fig. 1 is an operation principle block diagram of the present invention.
Embodiment the present invention includes several, and fixedly air surveillance platform and several move air surveillance platform and ground monitoring center.Can adopt fixed point to stay to be balloon or dirigible (in fill hydrogen or helium) the 200-1000 rice high-altitude of the going up to the air air surveillance platform that fixes, consider, select for use and adopt the less streamlined fixed point kite balloon airship of air resistance coefficient better from stable angle.Its height is controlled by hawser.Reflector, receiver, decoder are housed on the dirigible, The Cloud Terrace is equipped with in its bottom, high-definition camera, camera are housed on the The Cloud Terrace, be connected (also can pass through wireless transmission) by cable between ground monitoring center and the dirigible, the setting of The Cloud Terrace, camera head all describe in detail in the patent documentation of number of patent application 97225624 and number of patent application 97237482 in installation on the The Cloud Terrace and control circuit thereof.As shown in Figure 1, the picture signal of video camera and camera is sent by reflector, after the receiver that video transmission line transfers to the ground monitoring center receives, delivers to that supervisory control comuter is handled and storage and deliver to the large-screen image display and show again.The control command that supervisory control comuter sends is delivered to decoder by 485 protocol instructions transmission lines, delivers to The Cloud Terrace and video camera more respectively, adjusts its shooting angle and zoom respectively.Every dirigible approximately can be monitored 9-25 square kilometre zone.
Mobile air surveillance platform is made of the remote control airship that cruises.Digital radio station transmitter, receiver, decoder and high-energy battery are housed on the remote control airship, the remote control The Cloud Terrace is equipped with in the bottom, height degree of analysing video camera and camera are housed on the The Cloud Terrace, the ground monitoring center is furnished with corresponding digital radio station receiver and digital radio station, its operation principle as shown in Figure 1, the picture signal of video camera and camera is launched by the digital radio station transmitter, after the digital radio station receiver through being located at ground receives, delivers to supervisory control comuter processing and demonstration again.The control command that supervisory control comuter sends is launched by digital radio station, is received after decoder control The Cloud Terrace action and video camera zoom by the digital radio station receiver that is located on the remote control airship.
